DESCRIPTION OF THE PREFERRED EMBODIMENTS

(3) Regarding technical contents, features and effects disclosed above and other technical contents, features and effects of the present invention will be clearly presented and manifested in the following detailed description of the exemplary preferred embodiments with reference to the accompanying drawings which form a part hereof.

(4) FIG. 1 is a remote management system 100 with a master-slave architecture for performing a method for remote management of the using of chemicals according to the present invention. The remote management system 100 includes a master smart scale 120, at least one slave smart scale 140, a remote communication device 160, and radio frequency tags 180, 181 respectively attached to multiple chemicals 200, 300. The master smart scale 120 provides a master-slave mode for communicating with the slave smart scale 140 in the master-slave mode. The master smart scale 120 includes a weighing unit 122, a radio frequency reader 124, a micro server 126 and a statistical module 128. The weighing unit 122 is used for weighing the chemical 200 to generate a weight data, such as an initial weight W1 before the first use or a remaining weight WR1 after each use. The radio frequency reader 124 is used to read the radio frequency tag 180 attached on a container of the chemical 200 to generate an identification information ID1.

(5) The micro server 126 including a database 127 may be referred to as a mini-computer, which is capable of communicating with the remote communication device 160 via the Internet 130. In the embodiment, the micro server 126 receives multiple items of information including the weight data from the weighing unit 122, the identification information ID1 generated by the radio frequency reader 124, a statistical data SR generated by the statistical module 128, and the information and the weight data that are transmitted from outside the master smart scale 120 by the remote communication device 160 or the slave smart scale 140. Furthermore, the micro server 126 transmits the statistical data SR to the remote communication device 160.

(6) The slave smart scale 140 includes a weighing unit 142, a radio frequency reader 144, and a microcontroller 146. The weighing unit 142 is used for weighing another chemical 300 to obtain a remaining weight WR2. The radio frequency reader 144 reads the radio frequency tag 181 of the chemical 300 to correspondingly generate an identification information ID2. If the master smart scale 120 performs an initialization procedure for the chemical 300 to make the identification information ID2 of the chemical 300 stored in the database 127, then the microcontroller 146 of the slave smart scale 140 can communicate with the micro server 126 via the Internet after the master smart scale 120 enables the master-slave mode, so as to transmit the remaining weight WR2 and the identification information ID2 from the slave smart scale 140 to the database 127 for storing them into. While the master-slave mode is turned off, the master smart scale 120 and the slave smart scale 140 each operate independently, and store the weight data and the identification information obtained by themselves in their own memory. As switching to the master-slave mode, the slave smart scale 140 is allowed transmitting the identification information ID2 to the master smart scale 120 to confirm whether both of the basic information and the initial weight of the chemical 300 exist in the database 127 or not.

(7) The remote communication device 160 has a display unit to display an input page for users to input the data into the database 127, and to display the statistical data SR generated from the statistical module 128 when the users make inquiries about.

(8) The master smart scale 120 can receive the basic information of chemicals 200 and 300 entered by the remote communication device 160, and the identification information ID1, ID2 and the use record UR that are generated from the master smart scale itself 120 and the slave smart scale 140. Wherein the basic information, such as the chemical name N, the date of purchase P and the manufacturer M, are usually printed or attached on the containers like bottles or gallipot of the chemicals 200 and 300. On the other hand, the statistical module 128 performs a statistical operation to generate the statistical data SR based on the basic information, the identification information ID1, ID2 and the use record UR, and transmits the statistical data SR from the master smart scale 120 to the remote communication device 160. In this way, the supplier or manager can instantly know the remaining weights WR1, WR2 of the chemicals 200, 300 in the laboratory through the remote communication device 160 such as a mobile device or a computer, so as to solve the problem of the conventional technology.

(9) FIG. 2 is a method for remote management of the using of chemicals according to an embodiment of the present invention, which uses the remote management system 100 as shown in FIG. 1 to manage multiple chemicals 200, 300, 400 in a laboratory. The container of each of the chemicals 200, 300, 400 has a radio frequency tag attached on. The micro server 126 of the embodiment is a Raspberry Pi 126A. The database 127 is disposed on the Raspberry Pi 126A. The remote communication device 160 is a smart phone 160A. In the master-slave mode, the names of the slave smart scales 140, 140A are set into the master smart scale 120, so that the master smart scale 120 can recognize the slave smart scale 140 and allow receiving the information from the slave smart scales 140, 140A.

(10) Before each of the chemicals 200, 300, 400 is used for the first time, the master smart scale 120 is used to perform an initialization procedure for each of them. The initialization procedure includes steps as follows. The master smart scale 120 reads the radio frequency tags of the chemicals 200, 300 and 400 to respectively generate the identification information ID1, ID2, ID3 for the first time, weighs the chemicals 200, 300 and 400 to respectively obtain the initial weights W1, W2, W3 of them, and writes the initial weights W1, W2, W3 into the database 127 in itself. As the master smart scale 120 generates the identification information ID1, ID2, ID3 of the chemicals 200, 300 and 400 for the first time, the micro server 126 informs the remote communication device 160 to open an input page. For example, the micro server 126 generates a blank input page marked with the identification information ID1, ID2 or ID3 to transmit to the remote communication device 160 for the opening of the blank input page. Users can use the blank input page to enter the basic information of the chemicals 200, 300 and 400, such as the chemical names N1, N2 and N3 of the chemicals 200, 300 and 400, the date of purchase P1, P2, P3, and the manufacturer M1, M2, M3 into the database 127. And, the master smart scale 120 uses the identification information ID1, ID2 and ID3 to mark the basic information and the initial weights W1, W2, W3 that are stored in the database 127.

(11) After the user completes the initialization procedure for each of the chemicals 200, 300, and 400 with the master smart scale 120, he can select one from the master smart scale 120 and the slave smart scales 140, 140A in the master-slave mode to read the radio frequency tags of the chemicals 200, 300, 400 for respectively generating the identification information ID1, ID2, ID3, and to weigh the chemicals 200, 300, 400 at the same time to obtain the remaining weights WR1, WR2, WR3. At this time, the master smart scale 120 confirms whether both of the basic information of the chemical 200 and the initial weight W1 exist in the database 127 according to the identification information ID1 generated by itself. If so, the remaining weight WR1 is stored in the database 127. The slave smart scales 140, 140A transmit the identification information ID2, ID3 to the master smart scale 120, and confirm whether the basic information of the chemicals 300, 400 and the initial weight W2, W3 exist in the database 127. As the slave smart scales 140, 140A confirm that the basic information of the chemicals 300, 400 and the initial weight W2, W3 exist in the database 127, the slave smart scales 140, 140A transmit directly the remaining weight WR2, WR3 to the database 127 for storing into. Through the above process, the master smart scale 120 can collect multiple items of information about the chemicals 200, 300, 400 to generate their use records UR.

(12) In the embodiment, all steps of the initialization procedure must be executed by the master smart scale 120. The slave smart scale 140 cannot execute the initialization procedure. The function of the slave smart scales 140, 140A is only to read the radio frequency tags on the containers of the chemicals 300 and 400, weigh the chemicals 300, 400 to obtain the remaining weights WR2, WR3, and send the remaining weight WR2, WR3 to the database 127 of the master smart scale 120.

(13) It is worth noting that as the master-slave mode is turned off, each of the master smart scale 120 and the slave smart scales 140, 140A operates independently and stores the information obtained by itself such as the initial weights W2, W3, the remaining weights WR2, WR3 and the identification information ID2, ID3 into its own memory. After switching to the master-slave mode, the slave smart scales 140 and 140A need to confirm whether the initial information, such as the identification information ID2, ID3, the initial weights W2, W3 and the basic information of chemicals 300 or 400, exists in the database 127 or not, and then decide whether to store the remaining weight WR2, WR3 in the database 127 according to the previous confirmation. In other words, the master smart scale 120 must first complete the initialization procedure for each of the chemicals 300, 400, and then the slave smart scales 140, 140A can be allowed storing the remaining weight WR2, WR3 into the database 127.

(14) When users want to make an inquiry about the using of the chemicals 200, 300 and 400, he can use the smart phone 160A to open a specific page, such as a webpage or an application programming interface, to enable the statistical module 128 for performing a statistical operation according to the initial weights W1, W2, W3 and the use records UR in the database 127, so as to generate a statistical data SR of a single or multiple chemicals 200, 300, 400. Through the Raspberry Pi 126A, the statistical data SR and the basic information of the chemicals 200, 300, 400 are transmitted to the specific page.

(15) In one embodiment, the aforementioned use record UR includes the user name, the weighing time and the remaining weight WR1, WR2, WR3 of the chemicals 200, 300, 400. The basic information includes the chemical names N1, N2, N3 of the chemicals 200, 300, and 400, the date of purchase P1, P2, P3 and the manufacturer M1, M2, M3. The statistical module 128 inside the master smart scale 120 can calculate the number or frequency of use of the chemicals 200, 300, 400 according to the weighing time of the chemicals 200, 300, 400. The same one chemical 200, 300 or 400 may be packed in plural different containers respectively attached with plural radio frequency tags, and the radio frequency tags respectively correspond to plural different items of identification information. Take a single chemical 200 as an example, the statistical module 128 counts the number of the containers of the chemical 200 in the laboratory by searching for and counting the different items of identification information respectively corresponding to different containers according to the chemical name N1 of the chemical 200. In addition, the statistical module 128 can also calculate a used amount of the chemical 200 within a specific period for each of different users according to the chemical name N1, the user names, plural items of weighing time, the initial weight W1 and plural remaining weights.

(16) According to the method of the present invention, the user of the chemicals only needs to put the chemicals on the scale to record the weight after each use before put it back into the cabinet, the administrator can know the using states of the chemicals in the laboratory through the remote mobile device or computer. In this way, the user can accurately record the date of use, the number of times of weighing chemicals, the weighing frequency and the weight scaled each time, and then combined with the basic information and MSDS safety information of the chemicals. It can also greatly improve the experiment process, accuracy and safety.

(17) In addition, the suppliers of the chemicals can understand the use habits of users in real-time, so they can provide a renewal delivery and a consumer experience in a timely manner. At the same time, they can also make their own inventory management and logistics more economical and more efficient. For some special, environmental safety concerns or expensive drugs, they can get the daily use information, which is of great help to the overall management benefit.

(18) The conventional technology cannot perform a remote management of chemicals and does not have a master-slave mode. It is difficult to cope with the situation that different chemicals may be scattered in different laboratories. Compared with the conventional technology, the method of the present invention allows different people to query in real time or track at the same time the using states of multiple chemicals from different places, and can cope with the situations such as the manager may not be in the laboratory or different chemicals may be scattered in different laboratories. With the method of the present invention, the user only needs to weigh the chemical after each use, and can efficiently carry out the remote management of a variety of chemicals. There is no need to take out one by one container to know if there are any remaining chemical in it. In addition, the conventional technology generally activates the warning for a single chemical when the chemical is taken out and weighed. However, if the warning function is added based on the method of the present invention, warning messages for multiple chemicals can be sent at the same time. Since the network server of the present invention is built in the master smart scale, and there is no physical connection between the master smart scale, the slave smart scale and the remote communication device, if the system needs to be reset in case of laboratory relocation, it can be more convenient and faster.
