DETAILED DESCRIPTION

[0107] With dynamic weighing technology an accurate weighing of a vehicle can be performed while driving over conventional weighing bridges without stopping, using dynamic precision weighing methods. There are several advantages with the new dynamic weighing technology, e.g. increased capacity of the scale, time saving for the truck driver, less fuel consumption, less pollution, less noise, less wear and so on.

[0108] To fully make use of these advantages, conventional solutions for identification and registration of the vehicle has to be discarded. The conventional weighing terminals used for identification and registration of the vehicle requires the vehicle to stop to interact with the weighing terminal. Thereby, preventing a free flow of trucks moving over the weighbridge. Thus, it has been realised by the inventors that a solution is needed where the time and place for the identification and registration of the vehicle can be separated from the time and place for weighing of the vehicle.

[0109] The present invention provides a solution which captures readings from the weighing scale while the vehicle is driving over the weighbridge and can for instance use identification techniques to automatically identify the vehicle while driving, and furthermore uses a communication device for pre- or post-registration of supplementary weighing information. In this way, the identification and registration of the vehicle can be adapted to the natural flow of cargo from the place of loading to the place of unloading using these two natural stops to registrate supplementary weighing information. Of course, any other stop or time can be used to registrate supplementary weighing information as long as the supplementary weighing information about the transported cargo is at hand.

[0110] FIG. 1 shows schematically a weighing system 500 for dynamic weighing according to an embodiment of the invention. The weighing system 500 comprises a server 100, a communication device 200, and a weighing scale 400. In the weighing system 500, information associated with a vehicle 300 and its weight is exchanged between the server 100, the communication device 200, and the weighing scale 400. The information may be transmitted/signaled/transferred between communication nodes in the weighing system 500 using any communication method known in the art, such as wireless and/or wired communication over a wireless and/or wired communication systems, respectively. The weighing system 500 shown in FIG. 1 only comprises one server 100, one communication device 200, and one weighing scale 400. However, the invention is not limited thereto. In further embodiments, the weighing system 500 may instead comprise more than one server 100, communication device 200, weighing scale 400.

[0111] The communication device 200 is associated with the vehicle 300, meaning that there is a connection between the communication device 200 and the vehicle 300. The communication device 200 may e.g. be registered in the server 100 as associated with/connected to the vehicle 300. As shown in FIG. 1, the communication device 200 may be a standalone device with communication capabilities, such as a mobile phone, a laptop or any other suitable standalone communication device. However, the communication device 200 may also be a part of the vehicle, e.g. a communication unit integrated in the vehicle 300 with mentioned communication capabilities.

[0112] The weighing scale 400 comprise a weighing bridge Y and a weighing circuit C and is arranged for performing dynamic weighing of vehicles driving over the weighing bridge Y. At a dynamic weighing event, i.e. when a vehicle drives over the weighing bridge Y without making a stop, the weighing scale 400 determines weight information for the vehicle 300. Weight information may be any weight information gathered by the weighing scale 400 in the weighing procedure such as a determined weight of the vehicle but also other information associated with the weight information and/or the weighing event itself, such as e.g. direction of the vehicle, speed of the vehicle warnings, etc.

[0113] According to embodiments of the invention a dynamic weighing event for a vehicle 300 is performed at the weighing bridge Y of the weighing scale 400. At the dynamic weighing event, the weighing scale 400 obtains weight information WI for the vehicle 300. The obtained weight information WI is transmitted to the server 100, as shown in FIG. 1. Prior to, or after the dynamic weighing event at the weighing bridge Y of the weighing scale 400, the communication device 200 obtains supplementary weight information SWI associated with the dynamic weighing event for the vehicle 300. The communication device 200 transmits the obtained supplementary weight information SWI to the server 100, as shown with an arrow in FIG. 1.

[0114] Thus, the server 100 is configured to receive weight information WI for the vehicle 300 from the weighing scale 400, as well as supplementary weight information SWI associated with the dynamic weighing event from the communication device 200. As described above, the weight information WI for the vehicle 300 has been obtained by the weighing scale 400 at the dynamic weighing event, while the supplementary weight information SWI has been obtained by the communication device 200 prior to or after the dynamic weighing event. Based on the received weight information WI from the weighing scale 400 and the received supplementary weight information SWI from the communication device 200, the server 100 generates a weighing ticket WT for the vehicle 300. The weighing ticket WT may include the received weight information WI and the received supplementary weight information SWI and may further include additional information associated with the dynamic weighing event. The weighing ticket WT may be transmitted to the communication device 200, as shown with an arrow in FIG. 1. Hence, the communication device 200 is in such an embodiment configured to receive a weighing ticket WT for the vehicle 300 from the server 100. The weighing ticket WT may in embodiments be received in response to the transmission of the supplementary weight information SWI to the server 100. In other words, upon receiving supplementary weight information SWI associated with a dynamic weighing event for the vehicle 300 from the communication device 200, the server 100 may transmit the weighing ticket WT to the communication device 200. When the communication device 200 receives a weighing ticket WT, the communication device 200 may present the weighing ticket WT to a user/driver of the communication device 200 and/or forward the weighing ticket WT to another communication device, such as e.g. printer or a communication device or server in a logistic or business system.

[0115] FIG. 2 shows an embodiment of the server 100. In this embodiment, the server 100 comprises a processor 102, a memory 104, and a transceiver 106. The server 100 is coupled to the memory 104 and the transceiver 106 with coupling means 108 known in the art. The server 100 may further be configured for wireless and/or wired communications in wireless and/or wired communication systems, respectively. The wireless communication capability is provided with an antenna 110 coupled to the transceiver 106, while the wired communication capability is provided with a wired communication interface 112 coupled to the transceiver 106.

[0116] FIG. 3 shows an embodiment of the communication device 200. In this embodiment, the communication device 200 comprises a processor 202, a memory 204, and a transceiver 206. The communication device 200 is coupled to the memory 204 and the transceiver 206 with coupling means 208 known in the art. The communication device 200 may further be configured for wireless and/or wired communications in wireless and/or wired communication systems, respectively. The wireless communication capability is provided with an antenna 210 coupled to the transceiver 206, while the wired communication capability is provided with a wired communication interface 212 coupled to the transceiver 206.

[0117] FIG. 4 shows an embodiment of the weighing scale 400. In this embodiment, the weighing scale 400 comprises a processor 402, a memory 404, and a transceiver 406. The weighing scale 400 is coupled to the memory 404 and the transceiver 406 with coupling means 408 known in the art. The weighing scale 400 may further be configured for wireless and/or wired communications in wireless and/or wired communication systems, respectively. The wireless communication capability is provided with an antenna 410 coupled to the transceiver 406, while the wired communication capability is provided with a wired communication interface 412 coupled to the transceiver 406.

[0118] The server 100, communication device 200 and weighing scale 400 may conform to established communication standards, such as LTE, LTE Advanced, New Radio 5G, WiFi, etc. but are not limited thereto.

[0119] The weighing scale 400 may also comprise further components, units, elements, and devices not shown in FIG. 4. Non-limiting examples of such components, units, elements, and devices are a weighing bridge Y and a weighing circuit C (shown in FIG. 1). Mentioned weighing circuit C may comprise at least a first set of load sensors and a second set of load sensors coupled to a weight indicator. The first set of load sensors is arranged at the first side of the weighing bridge Y and the second set of load sensors is arranged at the second side of the weighing bridge Y. In an embodiment, the vehicle 300 passes over the weighing bridge Y from the first side to the second side, causing weight signals to be generated by the first set of load sensors and the second set of load sensors. These weight signals are transferred to the weight indicator and to a processing device, such as e.g. the processor 402, coupled to the weighing circuit C. The processing device may be a standalone device. However, the processing device may in some embodiments be part of the weight indicator or another device of the weighing scale 400.

[0120] As described with reference to FIG. 1, the communication device 200 is associated with a vehicle 300 and further configured to obtain supplementary weight information associated with a dynamic weighing event for the vehicle 300. The supplementary weight information may e.g. be associated to company name, commodity, order number, transporting company, vehicle identity, delivering customer, receiving customer, transportation company, description of goods; and generally useful information related to the weighing, such as what material is transported, loading and unloading site, seller of material, buyer of material, classification number (governmental requirements), etc. The communication device 200 may obtain the supplementary weight information based on an input from a user/driver 900 of the communication device 200 or an administrator handling transport orders or transactions. The user/driver 900 may e.g. enter the supplementary weight information using an input device of the communication device 100, such as a keyboard or microphone or camera of the communication device 200. However, also other input devices or means can be used for inputting the supplementary weight information. The user 900 of the communication device 200 can e.g. be the driver of the vehicle 300 or a person working with loading or unloading of the vehicle 300.

[0121] The supplementary weight information is obtained prior to or after the dynamic weighing event at the weighing bridge Y of the weighing scale 400. Thus, the place and time where the supplementary weight information is obtained is separated from the place and time where the dynamic weighing is performed. In other words, if the dynamic weighing event is performed during a time period, the supplementary weight information may be obtained at a time instance prior to or after the time period. Furthermore, the weighing bridge Y may have a first spatial location and the communication device 200 may obtain the supplementary weight information at a second spatial location different from the first spatial location. The second spatial location is remote from the first spatial location, e.g. not at the plant of the weighing scale. For example, the second spatial location may correspond to a loading site located in one part of a town or country, while the first spatial location may correspond to a location of a weighing scale 400 located in a different part of the town or country or even in a different country.

[0122] By separating the place and time where the supplementary weight information is obtained from the place and time where the dynamic weighing is performed, the user 900 of the communication device 200 does not have to stop the vehicle 300 during the dynamic weighing event to enter the supplementary weight information. Instead the supplementary weight information can be entered prior to the dynamic weighing event, e.g. at a loading site or other suitable site where a stop is anyway required. Alternatively, the supplementary weight information can be entered after the dynamic weighing event, e.g. at an unloading site or other suitable site where a stop is anyway required.

[0123] As described above, the server 100 receives supplementary weight information from the communication device 200 and weight information from the weighing scale 400. The server 100 matches the received supplementary weight information with the received weight information, to be able to generate a weighing ticket and transmit the weighing ticket to the correct communication device 100. To match the received supplementary weight information with the received weight information may mean to verify that the communication device 200 transmitting the supplementary weight information matches the weight information from the weighing scale 400, i.e. that the communication device 200 is verified to be the communication device 200 associated with the vehicle 300 for which weight information has been received from the weight scale 400, or vice versa. The verification may e.g. be performed by comparing information associated with the communication device 200 and/or the vehicle 300 with information associated with the weight information for the vehicle 300, as will now be described with reference to FIG. 5.

[0124] FIG. 5 shows matching of a communication device 200 to weight information using information received from the communication device 200 according to an embodiment of the invention. In the embodiment shown in FIG. 5, the communication device 200 obtains and transmits supplementary weight information to a server 100 prior to a dynamic weighing event for the vehicle 300. Hence, in step I the communication device 200 obtains supplementary weight information associated with a dynamic weighing event for the vehicle 300 at a weighing bridge Y of a weighing scale 400. The communication device 100 further transmits the obtained supplementary weight information to the server 100 in a first communication message Ml, as shown in step II.

[0125] When the dynamic weighing event for the vehicle 300 at the weighing scale 400 takes place, both the communication device 200 and the weighing scale 400 obtains information associated with the dynamic weighing event and transmits the obtained information to the server 200. The information is obtained at the dynamic weighing event for the vehicle 300 which may herein be understood to mean during the dynamic weighing event, e.g. from a time instance at which the vehicle 300 approaches the weighing bridge Y to a time instance at which the vehicle 300 has driven over and left the weighing bridge Y. In FIG. 5, the communication device 200 and the weighing scale 400 perform obtaining of information associated with the dynamic weighing event in steps III and V, respectively. As both step III and V are performed at the dynamic weighing event, they are performed at approximately the same time or at least close to each other in time. The transmission of the obtained information to the server 100, is performed in step IV by the communication device 200 and in step VI by the weighing scale 400. In FIG. 5, step IV and VI are shown to be performed at the same time. However, depending on implementation and processing in the communication device 200 and the weighing scale 400, step IV and VI may in embodiments instead be performed at different times.

[0126] The information obtained by the communication device 200 in step III may be at least one of a position information, a speed, a direction, and a timestamp for the vehicle 300 at the dynamic weighing event. The communication device 200 may obtain the position for the vehicle 300 at the dynamic weighing event using any positioning techniques such as GPS, mobile location services, etc. Furthermore, the communication device 200 may obtain the speed and direction for the vehicle 300 at the dynamic weighing event using any technique known in the art, e.g. using gyro-meters, accelerometers, positioning systems, or suitable sensors. To obtain the timestamp for the vehicle 300 at the dynamic weighing event the communication device 200 may e.g. use an internal clock.

[0127] When the communication device 200 has obtained the at least one position information, speed, direction, and timestamp in step III, the communication device 200 transmits the at least one obtained position information, speed, direction, and timestamp for the vehicle 300 at the dynamic weighing event to the server 100 in a second communication message M2, as shown in step IV. In an embodiment the second communication message M2 also comprises at least one identity of the vehicle 300 and an identity of the weighing scale 400 obtained by the communication device 100.

[0128] The information obtained by the weighing scale 400 in step V may be weight information, as well as at least one of a speed, a direction and a timestamp for the vehicle 300 at the dynamic weighing event. The weighing scale 400 may obtain the speed and the direction for the vehicle 300 at the dynamic weighing event using any technique known in the art, e.g. using gyro-meters, accelerometers, positioning systems or suitable sensors. Furthermore, when the vehicle 300 drives over the weighbridge Y of the weighing scale 400, the weighing scale 400 can obtain the speed from the weight information sampled during the passage. Also, the driving direction over the weighbridge Y may be given by the same procedure and the orientation of the weighbridge relative to compass direction, such as a compass direction, may further be registered in a database. To obtain the timestamp for the vehicle 300 at the dynamic weighing event the weighing scale 400 may e.g. use an internal clock.

[0129] When the weighing scale 400 has obtained the weight information and the at least one speed, direction, and timestamp in step V, the weighing scale 400 transmits the obtained weight information and the at least one speed, direction and timestamp for the vehicle 300 at the dynamic weighing event to the server 100 in a third communication message M3, as shown in step VI. In embodiments, the third communication message M3 may further comprise a position information for the weighing scale 400. The position information for the weighing scale 400 may in this case e.g. be pre-configured in the weighing scale 400.

[0130] The server 100 receives the at least one position, speed, direction and timestamp for the vehicle 300 at the dynamic weighing event from the communication device 200 in the second communication message M2. Furthermore, the server 100 receives the at least one speed, direction and timestamp for the vehicle 300 at the dynamic weighing event from the weighing scale 400 in the third communication message M3. Based on the received information, the server 100 may in step VII match the communication device 200 with the weighing information for the vehicle 300 received from the weighing scale 400. Step VII may comprise the server 100 comparing information received from the communication device 200 with information obtained internally in the server 100 or received from the weighing scale 400. For example, the server 100 may compare the position information received from the communication device 200 with a position information for the weighing scale 400. As previously described, the position information for the weighing scale 400 may be comprised in the third communication message M3, i.e. received from the weighing scale 400. However, the server 100 may instead obtain the position information for the weighing scale 400 from an internal or external database or from another server in the weighing system 500 or connected to the weighing system 500. Alternatively, the position information for the weighing scale 400 may be pre-configured in the server 100. If the position information received from the communication device 200 corresponds to the position information for the weighing scale 400 obtained internally or received from the weighing scale 400, the communication device 200 is considered to match the weighing information for the vehicle 300 received from the weighing scale 400. That the position information correspond to each other can herein be understood to mean that they are equal or do not differ more than a spatial threshold value, i.e. the positions are spatially/geographically close to each other.

[0131] Step VII may further comprise the server 100 comparing information related to the speed, direction and/or timestamp received from the communication device 200 with information related to the speed, direction and/or timestamp received from the weighing scale 400. If the speeds, directions, and/or timestamps corresponds to each other the communication device 200 is considered to match the weighing information for the vehicle 300 received from the weighing scale 400. That the speeds, directions, and/or timestamps correspond to each other could herein be understood to mean that they are equal or do not differ more than a threshold value related to the speed, direction and/or timestamp.

[0132] In embodiments of the invention, the server 100 is configured to determine the identity of the vehicle 300 based on at least one of the position information, the speed, the direction and the timestamp at the dynamic weighing event, and further configured to generate the weighing ticket further based on the determined identity of the vehicle 300. Thereby, the server does not need to receive the identity of the vehicle 300 from the communication device and/or the weighing scale 400 which means reduced communication payload; or the server 100 can use the determined identity of the vehicle to compare with an received identity of the vehicle for improving identification accuracy and hence also matching accuracy.

[0133] When a match between the communication device 200 and the weighing information for the vehicle 300 received from the weighing scale 400 has been determined in step VIII, the server 100 generates a weighing ticket for the vehicle 300 in step VIII. The server 100 generates the weighing ticket for the vehicle 300 based on the supplementary weight information received in the first communication message M1 and the weight information received in the third communication message M3. As the weighing ticket may be generated in step VIII based on a match in step VII, the server 100 may generate the weighing ticket further based on at least one of the position, the speed, the direction and the timestamp received from the communication device 200. Furthermore, the server 100 may generate the weighing ticket further based on at least one of the speed, the direction and the timestamp received from the weighing scale 400. The generated weighing ticket can further be transmitted to the communication device 200 in a fourth communication message M4, as shown in step IX.

[0134] FIG. 5 shows an embodiment in which the communication device 200 obtains and transmits supplementary weight information associated with a dynamic weighing event to the server 100 prior to the dynamic weighing event. However, the communication device 200 may in embodiments instead obtain and transmit supplementary weight information associated with the dynamic weighing event to the server 100 after the dynamic weighing event. In this case, the communication device 200 would perform step I and step II after steps III to VI has been performed. According to embodiments of the invention a communication device 200 may be matched to weight information for the vehicle 300 based on information from the weighing scale 400 instead of or complementary to the information from the communication device 200.

[0135] FIG. 6 shows such an embodiment, in which the server 100 matches the communication device 200 with the weighing information for the vehicle 300 based on information from the weighing scale 400. In the embodiment shown in FIG. 6, the communication device 200 obtains and transmits supplementary weight information to a server 100 prior to a dynamic weighing event for the vehicle 300. Hence, in step I the communication device 200 obtains supplementary weight information associated with a dynamic weighing event for the vehicle 300 at a weighing bridge Y of a weighing scale 400. The communication device 200 further transmits the obtained supplementary weight information to the server 100 in a first communication message Ml, as shown in step II.

[0136] The information from the weighing scale 400 used to match the communication device 200 with the weighing information for the vehicle 300 may be an identity of the vehicle 300 and an identity of the weighing scale 400. In FIG. 6, the weighing scale 400 obtains the identity of the vehicle 300 and the identity of the weighing scale 400 in step III. The weighing scale 400 may obtain the identity of the vehicle 300 at the dynamic weighing event e.g. by reading a RFID tag or scanning a bar code associated with the vehicle 300. In addition, the identity of the vehicle 300 may e.g. be obtained by using license plate recognition techniques. The identity of the weighing scale 400 may e.g. be pre-configured in the weighing scale 400. Step III may further comprise the weighing scale 400 obtaining weight information for the vehicle 300 at the dynamic weighing event, as described with reference to FIG. 5.

[0137] The weighing scale 400 transmit the information obtained in step III to the server 100. In the embodiment shown in FIG. 6, the weighing scale 400 transmits the identity of the vehicle 300 and the identity of the weighing scale 400, as well as weight information for the vehicle 300, to the server 100 in a fifth communication message M5, as shown in step IV. However, the weight information for the vehicle 300 may in embodiments instead be transmitted in a separate communication message, such as e.g. the third communication message shown in FIG. 5.

[0138] The server 100 receives the identity of the vehicle 300 and the identity of the weighing scale 400 from the weighing scale 400. The server 100 may use the received identity of the vehicle 300 and identity of the weighing scale 400 to match the communication device 200 with the weighing information for the vehicle 300 in step V. For example, the server 100 may compare the identity of the vehicle 300 received from the weighing scale 400 with an identity of the vehicle 300 derived from information received from the communication device 200 in the first communication message M1. If the two identities are the same the communication device 200 is considered to matches the weighing information for the vehicle 300. In this case, the server 100 generates a weighing ticket in step VI, where the weighing ticket is further based on the received identity of the vehicle 300 and the received identity of the weighing scale 400. The generated weighing ticket can further be transmitted to the communication device 200 in a fourth communication message M4, as shown in step VII. In case the second communication message M2 from the communication device 100 also comprises at least one identity of the vehicle 300 and an identity of the weighing scale 400, such identities can be used to determine if the communication device 200 matches the weighing information for the vehicle 300.

[0139] Any method according to embodiments of the invention may be implemented in a computer program, having code means, which when run by processing means causes the processing means to execute the steps of the method. The computer program is included in a computer readable medium of a computer program product. The computer readable medium may comprise essentially any memory, such as a ROM (Read-Only Memory), a PROM (Programmable Read-Only Memory), an EPROM (Erasable PROM), a Flash memory, an EEPROM (Electrically Erasable PROM), or a hard disk drive.
