monitoring Center:
Hardware: Servers, computers, printers, large display screens, switches, etc.
Software: water-saving irrigation system platform, database software, operating system software.
Communication network:
GPRS/4G/LoRa
Valve control system:
The valve monitoring system consists of valve control, solenoid valve and field controller.
The valve control system is to realize the interception and distribution functions of the farmland irrigation subregional operation pipe network. The system adopts a full wireless roaming network, and there is no need to lay lines on site. Remote data transmission is achieved through partition management and cascaded communication. Each solenoid valve has a special name. The solenoid valve opens according to the schedule established by the rotation. The monitoring center issues instructions to the designated solenoid valve or irrigation group to open the solenoid valve for watering, or close the solenoid valve to stop watering. According to the soil moisture content, the valve controller can be linked to realize automatic irrigation. The soil moisture value is set in the system. When the soil moisture is lower than the set value, the solenoid valve is opened for irrigation, and when the value is reached, the solenoid valve is closed to stop irrigation. The valve controller is connected with the solenoid valve through the cable, the valve controller communicates with the field controller through wireless (Lora), and the field controller sends the valve switch instruction to the valve controller through the Lora communication method.
Soil Moisture Monitoring System:
The soil moisture monitoring system consists of valve controller, soil temperature and humidity sensor and field controller.
The soil moisture monitoring system mainly collects and processes soil moisture. It can be managed through an all-digital network platform, and the data collected by the front-end digital can be sent back to the control center and each monitoring center through the wireless communication terminal through the GPRS/4G network to realize the distributed monitoring, centralized control and management of the following functions.
The soil temperature and humidity sensor is connected to the valve controller through a 485 cable. The valve controller communicates with the field controller through Lora, and the collected data is uploaded to the monitoring center by the field controller through the 4G network.
Pump control system:
The water pump control system consists of electric well controller, PLC and water meter.
The water pump control system monitors parameters such as the power consumption of the deep well submersible pump, the operating status of the pump set, and the pipeline flow, and transmits it back to the control center and each monitoring center through the GPRS/4G network to realize distributed monitoring, centralized control, management and other functions
