And the water flow power generation unit is arranged between the water inlet of the adjusting valve and the farmland water outlet pile, and the water flow power generation unit is connected with the charging interface of the main control board. When water flows through the water flow power generation unit, kinetic energy is converted into electric energy, and the main control board is provided with electric energy. The problem that the use of large batteries leads to high cost or the use of solar panels for power generation has many restrictions. The water flow power generation is used to charge the charging battery on the main control board, and the power demand of the irrigation device when irrigating crops is ensured.

The water outlet end is connected with the water inlet of the regulating valve 30. The water flow power generation module 102 is embedded in the structure of the water flow guide pipe 101, and there is an included angle between the installation position of the water flow power generation module 102 and the water flow direction, which is used to convert the kinetic energy of the water flow flowing through the water flow power generation unit into electric energy.

[0057] Optionally, Figure 4 Another structural example of the water flow power generation unit is provided in the utility model. As shown in Figure 4 The water flow power generation unit also includes a filter screen 103.

[0059] In the water flow power generation process, the water flow power generation unit converts kinetic energy into electric energy and transmits the electric energy to the charging interface on the main control board, and finally transmits the electric energy to the charging battery through the battery charging circuit and the battery protection circuit. In addition, when passing through the battery charging circuit, the electric energy can directly flow through the power supply circuit and supply power to the main control MCU, each detection circuit and other modules. The main control MCU is connected with each module and each detection circuit. Each module is connected with an antenna.

[0060] The battery protection circuit is designed, such as charging, over-discharge, over-current, short-circuit protection, to protect the safe use of the battery. The battery charging circuit is designed, when the water flow flows, the water flow power generation unit can charge the battery in the control unit. At the same time, the temperature detection circuit is designed to detect the current battery temperature, and when the temperature is too low or too high, the battery is not allowed to discharge large current (such as controlling the actuator to rotate). In addition, the power detection circuit is set to detect the battery power in real time, and the user can be informed of the current battery power in time, so that the user can replace the battery in time. The mobile communication module includes 2G / 3G / 4G / 5G mobile communication mode, BT Bluetooth / WiFi mode. The 2 / 3 / 4 / 5G mobile communication mode communicates with the server, and the BT Bluetooth / WiFi mode is used to directly connect with the mobile phone Bluetooth. In order to deal with the situation that the water outlet post in the sparsely populated area has poor or unstable network signal, and the network signal is affected by crops, the control unit uses two 2 / 3 / 4 / 5G mobile communication networks and two SIM cards of different operators to realize the function of double network and double communication, and the two operators are always connected with the cloud server at the same time. The control unit automatically selects the operator network with the best signal strength to upload data to the cloud server, and the cloud server automatically selects the operator network with better signal strength to communicate and interact with the mobile communication network module of the master station device, to ensure that the communication and interaction between the cloud server and the master station device can be realized as long as there is any operator network in the area, and the adaptability of the master station device to the network environment is improved. When the control unit is installed in a mobile network environment, the mobile phone APP can realize remote control of the control unit through the mobile communication module and the server. When the control unit is installed in an environment without mobile network, the mobile phone APP can directly connect the control unit through the BT Bluetooth / WiFi module and operate and control the control unit, which is a supplement to the network environment and improves the environmental adaptability of the irrigation device.

[0061] A patch-type high-precision air pressure sensor is arranged in the water pressure detection circuit, an air pressure detection port is led out on the control unit shell, and the water pressure ports of the water outlets of the regulating valve are connected through the water pressure guide pipe. The water pressure of the water outlet of the regulating valve is detected by detecting the air pressure.

[0062] The current detection circuit is designed, and when the circuit current is too large, protection is performed, and the main control board controls the actuator to stop rotating, to prevent the regulating valve from blocking and causing large current damage to the actuator.

[0063] The high-precision positioning module is arranged, the current position of the irrigation device can be accurately positioned and transmitted to the server and the mobile phone APP, the user can conveniently check the detailed position of the current control unit, and the control unit can be conveniently tracked and found back after being stolen. For example, when the control unit is in a mobile network environment, the control unit uploads the detailed position of the current control unit to the server and the user APP after being started, and is updated in time in the later period; when the control unit is in a mobile network environment, the control unit transmits the detailed position of the current control unit to the user APP through Bluetooth / WiFi after being started, and the detailed position of the control unit is transmitted to the server as soon as possible after the user's mobile phone is connected to the network; when the server finds that the position of the control unit changes more than a range (such as a land area), the original APP account is warned, the change of the position of the device is warned, and the risk of being stolen exists.

[0064] The antennas in the control unit, namely the mobile communication network antenna, the Bluetooth antenna and the high-precision positioning module antenna, are all arranged in a built-in mode; the irrigation device does not need to be externally connected with any external antenna, the equipment has high integration, and is easy to install.

[0065] The main control MCU in the control unit mainly adopts a low-power chip, and the power supply chip adopts a high-efficiency power supply chip. The main control MCU is in active sleep when not working, and can be awakened at any time.

[0066] All the circuits and modules in the control unit work only when being powered on, and are in a power-off state when not being used.
