Definitions
- the present invention is concerned with the application of crop protection agents, fertilizers and / or pesticides with the aid of a (preferably portable) spray device or a small device (such as a bicycle sprayer).
- An object of the present invention is a monitoring module with which existing spraying devices can be equipped in order to control, track and / or document the spraying process. Further subjects are a method, a system and a computer program product for monitoring spraying processes.
- Sprayers are extensively described in the prior art. In agriculture, sprayers are used to apply pesticides or fertilizers (see e.g. WO2018 / 108696A1, DE102013109785A1, EP0143588A2, EP0256744A1). Sprayers are also used in forestry (e.g. US20050121462A1) or pest control (see e.g. W02018011009A1, W02018011010A1, W02018011011A1,
- a hand-held spray device can be equipped with several nozzles via a small bar.
- the spray is conveyed from the container through spray lines to the nozzle holder and through the at least one nozzle onto one or more target objects while the user walks through the target area.
- the application rate depends on the walking speed, the spray width and the amount of spray required per unit of time. Since the application parameters mentioned usually vary during an application process (humans are not machines), the application rate is uneven across the target area. This can result in too little or too much spray being applied. Too low an application rate can result in ineffectiveness of the spray. Too much can cause unnecessary costs or even damage.
- the spray usually consists of a carrier liquid (water) and one or more active ingredients (eg a herbicide, fungicide, pesticide) and / or nutrients.
- active ingredients eg a herbicide, fungicide, pesticide
- the spray must first be prepared by diluting (e.g.) a concentrate with a carrier liquid (water).
- the right degree of dilution must be found in order to apply a defined amount of active ingredient / nutrients per unit area to reach.
- the degree of dilution to be set depends on the spray width and the walking speed of the person carrying out the spraying process.
- the correct degree of dilution therefore depends on which nozzle (s) is / are used, at what height the nozzle (s) is / are guided over the target area, how much spray comes out of the nozzle (s) per unit of time and how fast it is the person moves through the target area.
- WO2018 / 108696A1 discloses a portable sprayer comprising a flow meter, a distance sensor and a signal transmitter.
- the sprayer is configured to interact with a mobile computer (e.g. a smartphone).
- a mobile computer e.g. a smartphone
- the walking speed of the user of the portable sprayer can be determined.
- the application rate released per unit of time can be determined.
- the spray width is determined in an upstream calibration process.
- WO2018 / 108696A1 thus discloses solutions to the problems described above. However, in order to benefit from the solutions, a user must purchase a new, appropriately equipped sprayer. It would be advantageous to be able to use the solutions described in WO2018 / 108696A1 with an already existing spray device.

- steps are listed in a sequence, this does not necessarily mean that the steps also have to be carried out in the specified sequence. Rather, the invention is to be understood in such a way that the steps listed in an order can be carried out in any order or also in parallel with one another, unless a step is based on another step, which is evident from the description of the steps in each case becomes clear.
- the sequences listed represent preferred embodiments of the invention.
- the monitoring module is used to track and / or monitor (control) and / or document a spraying process by means of a spray device, the spraying process being carried out by a human user.
- a spraying process describes the application of one or more sprays to one or more target objects in a target area.

- the monitoring module according to the invention can be understood as a retrofit kit for existing (preferably portable) spraying devices with which the existing spraying devices can be equipped with extended functionalities in order to control, track and / or document spraying processes.
- Synonyms for the term "monitoring module" are, for example, monitoring unit, monitoring device,
- Spray application control module and / or the like.
- spray device includes spray devices that can be carried by a human user on their back and / or in the hand; however, the term is not limited to such spray devices. Spray devices that can be moved, for example, with mechanical aids (for example bicycle sprayers) should also be included in the term “spray device (s)”.

- portable spray devices are disclosed in: WO2018 / 108696A1, DE102013109785A1, EP0143588A2, EP0256744A1, US20050121462A1, W02018011009A1, W02018011010A1, W02018011011A1, W02018011011A1, US020180110200249A1, US02018011020024A1, US02018011020024A1,
- the monitoring module according to the invention is designed for easy integration into a large number of spray devices.
- Spray devices usually include a container in which the spray to be applied is located. Furthermore, they comprise at least one nozzle via which the spray means leaves the spray device during a spraying process. Usually, the at least one nozzle transforms the spray that passes through it into drops with a specific one Droplet size distribution, which depends, among other things, on the pressure in front of the nozzle, the flow rate of the spray and the type of nozzle.
- the monitoring module according to the invention is introduced into a line of a spray device between the container of the spray device and the at least one nozzle of the spray device.
- the container and the at least one nozzle are in fluid communication via the line between the container and the at least one nozzle.
- the monitoring module is integrated into this fluid connection, the fluid connection between the container and the at least one nozzle (after integration) being maintained.
- the monitoring module has two connection elements, a first connection element and a second connection element.
- the first connection element is used to connect the monitoring module to that part of the line which is directed upstream. This is the part of the line that leads to the container. Spray that flows from the container in the direction of the at least one nozzle flows through this part of the line and from there reaches the monitoring module.
- the second connection element is used to connect the monitoring module to that part of the line which is directed downstream. This is to be understood as meaning the part of the line that leads to the at least one nozzle. Spray medium flowing from the container in the direction of the at least one nozzle first flows through the monitoring module and then through this part of the line to the at least one nozzle.
- the connecting elements can be designed, for example, as hose nozzles.
- the line between the container and the at least one nozzle of a spray device is often designed as a flexible hose. It is conceivable to cut through the hose at one point and pull the two hose ends (hose openings) created over the two hose nozzles of the monitoring module, with one hose nozzle taking over the function of the first connecting element and being connected to the hose end via which you can (upstream ) reaches the container, and the other hose nozzle takes over the function of the second connecting element, via which one arrives (downstream) to the at least one nozzle.
- Hose clamps can be used to additionally fix the hose ends to the nozzles.
- connecting elements are disclosed in the prior art (see e.g. DE102017000008, DE19818085, DE102017004353, SE7611659, DE4139742, DE2523338, DE3218965, DE4211498, GB8511911, DE3617199, DE9319397).
- the monitoring module comprises a flow chamber. It is located between the two connecting elements. As a result of the monitoring module introduced into a line of a sprayer, the spray medium flowing from the container of the sprayer in the direction of the at least one nozzle of the sprayer is forced to flow through the flow chamber.
- a flow meter is located in the flow chamber. This flow meter records the amount of spray medium flowing through the flow chamber per unit of time. Amount is understood to mean the volume or the mass, depending on the measurement method used.

- an impeller sensor is used for flow measurement.
- the measuring principle is based on the fact that an impeller assumes a speed proportional to the flow speed of a fluid by which the impeller is driven.
- a permanent magnet which moves with the impeller, can be attached to the impeller to measure the speed.
- a Hall sensor which the permanent magnet moves past, can be used as a pulse counter. The number of pulses measured per unit of time is proportional to the speed of the impeller and thus to the flow rate of the fluid.
- the monitoring module also includes a control unit, a transmission unit and a power supply unit.

- the term “to follow a route” means that the route tracking unit is configured to determine the position by means of a GPS sensor at defined time intervals and / or at defined times and / or when defined events occur (the position of the GPS sensor being determined is) and to store the position in a data memory (preferably together with the time at which the position has been determined).
- GPS sensor Global Positioning System
- a satellite navigation system is based on satellites that continuously broadcast their current position and the exact time using coded radio signals.
- a receiver (referred to as the GPS sensor in this description) can calculate its own position and speed from the signal propagation times.
- Well-known satellite navigation systems are, for example, NAVSTAR GPS, GLONASS, Galileo or Beidou.
- GPS sensor should not be understood as limiting with regard to the GPS satellite navigation system; it should also include receivers of other satellite navigation systems.
- the position of the GPS sensor can be determined with the route tracking unit. If the GPS sensor is carried along with the monitoring module and / or with the sprayer and / or with the mobile computer system, then the position of the monitoring module and / or the sprayer and / or the mobile computer system can be determined.
- a user moves the sprayer together with the monitoring module (and possibly the mobile computer system) through a target area in which the user sprays an area or one or more target objects with a spray agent.
- the route taken by the user covered can be tracked and recorded (stored in a data memory) with the route tracking unit. Furthermore, the speeds at which the user moves through the target area can be recorded, tracked and recorded.
- the "target area” is the spatial area in which one or more target objects are / are to be sprayed with one or more spray means.
- the "target object” / the “target objects” can be one or more plants, one or more areas of a field (e.g. the arable land), walls, paths, roads, rails or other objects.
