Hardware
The main idea is to achieve the automation of pesticide sprayer and the complete liberation of replenishment. In order to accomplish the above ideas, we plan to equip an automated pesticide spraying vehicle and a replenishment station. Considering the ruggedness of the farmland, we plan to use off-road tires and increase the tire radius. In addition, we consider the motor capacity, as well as the up and downhill issues, we plan to use plastic housing. The first step of automation is to realize the automation of movement. We plan to realize automatic movement through automatic tracking or magnetic induction.
The first step of automation is to realize mobile automation. We plan to realize automatic movement through automatic line hunting.
After that, we want to automate the overall spraying and replenishment. We equip the sprayer with a water tank and a nozzle. We are going to use atomizing nozzle and calculate the spraying area, rate, and time length through modeling to ensure that the pesticide spraying is as uniform as possible. However, pesticide spraying must be consumed. In order to achieve full automation, we set up replenishment stations to connect water pipes and wires. On the water tank of the pesticide spraying truck, we expect to make an automatically openable "skylight" through the mechanical transmission structure. After arriving at the replenishment station, the skylight can be opened, and pesticides can enter the water tank through the water pipe and "skylight" to complete the replenishment. In order to realize this idea, we are going to set up a pressure plate under the water tank and connect the signal transmitter, and connect the receiver at the "sunroof" and the water pipe. The strength of the signal will decrease as the pressure decreases, so that the car will pass by. There is sufficient medicine at every supply station.
The last problem is motor supply. We are going to connect the plug of the replenishment station to the charging port on the car through the hydraulic transmission device. The matching of the charging plug relies on the cooperation of the color sensor and the inverted cone groove. The color sensor is used to narrow the range, and the inverted cone groove can increase the greater fault tolerance rate.
