A field precision water-saving irrigation controller

Abstract

The invention discloses a field precise water-saving irrigation controller. The field precise water-saving irrigation controller is characterized in that a low-power-consumption ZigBee chip and a low-power-consumption ARM master control circuit are used, a low-voltage charging drive electromagnetic valve is used, a battery pack formed by four common No.5 alkaline dry batteries is used to supply power, four 12V voltage pulse electromagnetic valve switches can be driven, and the controller can work for at least two irrigation seasons. The field precise water-saving irrigation controller has the advantages that the controller is matched with four irrigation electromagnetic valves, the working states and accumulation flow of each irrigation control valve can be monitored accurately, a low-power-consumption field automatic irrigation system can be built conveniently and fast, and the whole controller is low in cost, low in project implementation cost, low in operation and maintenance cost and capable of facilitating the popularization and application of an automatic precise irrigation system.

Description

technical field [0001] The invention relates to a field precision water-saving irrigation controller, which belongs to the technical field of farmland water conservancy irrigation. Background technique [0002] The irrigation controller is generally used as a part of the automatic irrigation system, and is mainly used in the automatic irrigation system to receive the control instructions of the upper computer system to realize the opening and closing control of the electromagnetic valve under its jurisdiction. Since automated irrigation systems are mainly used in the agricultural field, most irrigation automation systems are in the application demonstration stage and enjoy preferential policies such as government agricultural subsidies. And maintainability design is relatively lacking. Once large-scale promotion and application are required, the system functions will not vary much, and cost will inevitably become the primary consideration for users. [0003] The current ir...

[0007] 2) High power consumption, need to be equipped with solar panels and batteries

[0008] Since the current devices are mostly powered by solar panels and batteries, there is no mention of the use of ordinary alkaline dry batteries for power supply, which is closely related to the power consumption of the device. It can be inferred that the design of the current device has not been designed for low power consumption or There are deficiencies, and it is impossible to use low-voltage alkaline dry battery packs to drive solenoid valves that require high current and high voltage.

The power consumption of the device is high, and additional solar panels and batteries are required. On the one hand, the overall cost of the system is increased, and on the other hand, the maintenance cost of the system such as anti-theft also increases accordingly

[0009] 3) The function is missing, and there is no solenoid valve status monitoring function;

[0010] Existing irrigation controllers do not have feedback on the working status of the controlled solenoid valves, and users cannot accurately know the working status of each irrigation control valve, and cannot find problems and troubleshoot them in time, which may lead to further deterioration of device failures and cannot be guaranteed Operational Performance of Irrigation Systems

[0011] 4) lack of function, no accurate flow measurement function

The current valve controller is still lacking in its own accurate flow measurement
