DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0266] The invention is explained in more detail below with reference to figures, without wishing to restrict the invention to the features and combinations of features that are shown in the figures.

[0267] FIG. 1 schematically shows an embodiment of the monitoring module according to the invention. The monitoring module (10) comprises a first connecting element (11) and a second connecting element (12) for integrating the monitoring module into a line of the sprayer between a container for spray composition and at least one nozzle. The monitoring module (10) further comprises a flow chamber (13) between the first connecting element and the second connecting element. The arrows A and B indicate the direction of flow of a spray composition which flows from the container of the sprayer through the flow chamber (13) in the direction of the at least one nozzle. Arrow A denotes the direction of flow of the spray composition which comes from the direction of the container and enters the flow chamber (13); arrow B denotes the direction of flow of the spray composition which leaves the flow chamber (13) again in the direction of the at least one nozzle. In the nozzle there is an impeller (18) which is set in rotation by the spray composition which flows through the flow chamber (13). A permanent magnet (19) is attached to the impeller (18). The permanent magnet (19) moves past a Hall sensor (14) when the impeller (18) rotates. The Hall sensor (14) is used as a pulse counter. The pulses are forwarded to a controller (15). The impeller (18), the permanent magnet (19) and the Hall sensor (14) together form a flow sensor. The controller (15) determines the speed of the impeller from the pulses per unit time and the flow rate of the spray composition from the speed of the impeller. The flow rate of the spray composition can be transmitted to a (separate) computer system by way of a transmitter (16). An energy supply (17) is used to supply the flow meter (14, 18, 19), the controller (15) and the transmitter (16) with electrical energy. All components of the monitoring module (10) are attached to a housing (20) or accommodated in the housing (20).

[0268] FIGS. 2a to 2c schematically show how a monitoring module according to the invention can be integrated into a line of a sprayer. FIG. 2a shows the sprayer. The sprayer comprises a first container (22) containing a first liquid and a second container (23) containing a second liquid. The second liquid can be an active substance concentrate, for example, and the active substance can be a pesticide. The first liquid can be a diluent for the active substance concentrate, for example can be water.

[0269] The first liquid is conveyed out of the first container (22) in the direction of at least one nozzle (27) via a first conveying means (24), such as, for example, an electrically driven pump. The second liquid is conveyed out of the second container (23) in the direction of at least one nozzle (27) via a second conveying means (25), such as, for example, an electrically driven pump. The liquids mix on their way through the line (28). A mixture of the first and second liquids exits the at least one nozzle (27). A shutoff valve (26) can be used to stop the flow.

[0270] FIG. 2a schematically shows that the line (28) between the containers (22, 23) and the at least one nozzle (27) is cut at one point (indicated by the scissors). FIG. 2b shows that the line (28) between the containers (22, 23) and the at least one nozzle (27) has been cut. The fluid connection between the containers (22, 23) and the at least one nozzle (27) is broken. The monitoring module (10) according to the invention is integrated at the location of the break. For this purpose, the monitoring module (10) has a first connecting element (11) and a second connecting element (12). The first connecting element (11) is connected to that part of the line (28) which leads upstream in the direction of the containers (22, 23). The second connecting element (12) is connected to that part of the line (28) which leads downstream in the direction of the at least one nozzle (27). FIG. 2c shows the monitoring module (10) integrated in the line (28). The fluid connection between the containers (22, 23) and the at least one nozzle (27) is restored by the monitoring module (10). Liquid which flows out of the containers (22, 23) in the direction of the at least one nozzle (27) flows through a flow chamber (13) of the monitoring module.

[0271] FIG. 3 schematically shows an embodiment of a system according to the invention. The system (40) comprises a monitoring module (10) and a computer system (30). The monitoring module (10) can be, for example, the monitoring module shown in FIG. 1. The monitoring module is configured to transmit data about the quantity of a spray composition which flows through a flow chamber of the monitoring module per unit time to the computer system (30). The computer system (30) comprises a receiver (31), a controller (32) and an output unit (33). The controller (32) is configured to cause the receiver (31) to receive the data transmitted by the monitoring module (10). The controller (32) is further configured to cause the output unit (33) to display the data to a user.

[0272] FIG. 4 schematically shows a further embodiment of the system according to the invention. The system (40) comprises a monitoring module (10) and a computer system (30). The monitoring module (10) is configured to measure quantities of spray composition which flow through a flow chamber (not explicitly shown) of the monitoring module (10) per unit time and to transmit data about these quantities to the computer system (30) by way of a transmitter (not explicitly shown) of the monitoring module. The computer system (30) comprises a receiver (31), a controller (32), a quantity determiner (36), a route tracker (35) with a GPS sensor (34) and an output unit (33). The quantity determiner (36) and the route tracker (35) can be part of the controller (32). The controller (30) is configured to cause the receiver (31) to receive the data about the quantities of spray composition which flow through the flow chamber per unit time from the monitoring module (10). The controller (32) is further configured to cause the route tracker (35) to track the route along which the computer system (30) (or the GPS sensor (34) as part of the computer system (40)) is moved. The controller (32) is further configured to cause the quantity determiner (36) to use the data transmitted by the monitoring module (10) to determine quantities of spray composition which are applied per unit time using the sprayer along the route. The controller (32) is further configured to cause the output unit (33) to display information about the route and about the quantities of spray composition which are or have been applied along the route to a user.

[0273] FIGS. 5 to 8 show screenshots of a mobile computer system for assisting a spraying process and for checking, tracking and documenting the spraying process.

[0274] FIG. 5 shows the successful completion of a calibration method which is assisted by a computer program on the mobile computer system. The values determined can be presented to the user as shown. The data are stored in the system and are used to check compliance with the spray parameters later on.

[0275] FIG. 6 shows displays of the computer program during a spraying process. The average quantity of spray composition which flows through the flow chamber per unit time is shown at the top as a function of time. The dashed line indicates the guideline value, determined during calibration, which the user should adhere to in order to achieve an optimum spraying result. The speed at which the user moves through the target area is shown in the middle as a function of time. The dashed line indicates the guideline speed at which the user should move in order to achieve an optimum spraying result. The application rate per unit area is shown at the bottom as a function of time. The dashed line indicates the guideline value which should be attained in order to achieve an optimum spraying result.

[0276] FIG. 7 displays a summary of variables after a spraying process. It shows how long the spraying process lasted (Duration), what distance the user covered (Distance), what area he sprayed (Area), how high the arithmetically averaged flow rate was (Flow), what volume of spray composition has been sprayed (Volume), how high the arithmetically averaged speed of the user was (Speed) and what the accuracy of the position is (GPS accuracy). In addition, the data of a calibration carried out previously and parameters input at the beginning of the spraying process (for example area description, culture) are displayed.
