Problems solved by technology

These all increase the size of the device, increase the cost of the body and installation, reduce portability and mobility, and make it difficult to adapt to the field working environment
[0007] In recent years, many wireless transmission module ZigBee node control transmission methods have been used for sensor network technology transmission. This form can carry out long-distance signal transmission, but the system is complex, the price is much higher than this technical solution, and the wireless transmission network operation fee or The construction of a wireless transmission base station will have a certain cost of use after completion

Embodiment Construction

[0041] In the present invention, the remote control keyboard 1 inputs the command and transmits the command from the remote control 2 to the main controller 5 through the infrared transmitter 4, and then the main controller 5 sends an execution command to the solenoid valve 8 according to the control mode required by the command to control the solenoid valve 8. In the self-feedback mode, soil moisture and rainfall detection feedback signals are sent to the main controller 5 through the soil humidity and rainfall sensor 7, and the opening and closing control of the solenoid valve 8 is performed according to the instruction setting.

[0042] Microprocessor adopts low power consumption chip, its built-in FLASH program memory and RAM data memory, by simplifying the hardware, improving the output driving mode, using the remote control to replace the keyboard and other measures, the power consumption of the device is effectively reduced. Only 4 1.5V batteries are needed to maintain o...

Abstract

The invention discloses an automatic control system for micro-irrigation. The system is used for agricultural micro-irrigation work including drip irrigation and microspray irrigation, and comprises a main controller and a remote controller. The main controller comprises an infrared receiver. The remote controller comprises an infrared transmitter. The remote controller wirelessly transmits data to the main controller in an infrared mode. The remote controller comprises a keyboard and a display screen. A soil humidity sensor, a rainfall sensor and an electromagnetic valve are connected with the main controller. Soil humidity and rainfall detection is conducted through the soil humidity sensor and the rainfall sensor, and switch-on and switch-off control instructions are sent to the electromagnetic valve. A clock is arranged in the remote controller. The main controller and the remote controller are low-voltage micro-static power consumption chips; a solar rechargeable cell can be adopted as a power supply. Running mode parameters of the main controller are wirelessly transmitted to the main controller in an infrared mode after being edited on the remote controller and stored.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation equipment, in particular to an automatic control system for micro-irrigation. Background technique [0002] Micro-irrigation (including drip irrigation and micro-spray irrigation) in agricultural production can control the temperature and humidity in the range of micro-irrigation operations and provide good growth conditions for crops, so it is widely used by countries all over the world. Drip irrigation can save a lot of water, electricity, and labor, and its superiority is increasingly valued by people. The micro-irrigation system generally consists of the tail: dripper, micro-sprinkler, anti-drip valve; the head: pump set, filter, fertilizer applicator, electrical control cabinet; the middle connection: dry, branch pipes, valves and other components. In the past, these components All switch controls are manually operated. Due to the long time of micro-irrigation operation, fre...
