1. Introduction to the system
Aiming at the wide distribution of agricultural fields, multiple monitoring points, wiring and power supply difficulties, the system uses the Internet of Things technology, adopts high-precision soil temperature and humidity sensors and intelligent weather stations, and remotely collects soil moisture and meteorological information online to achieve moisture (drought conditions). ) Automatic forecasting, intelligent decision-making of irrigation water consumption, remote/automatic control of irrigation equipment and other functions.
The system divides different types of areas according to soil types, irrigation water sources, irrigation methods, crops, etc. in different areas, selects representative plots in different types of areas, and automatically collects information such as soil water content, groundwater level, and rainfall. , Monitoring point of transmission function. Through the combination of irrigation forecast software and real-time information monitoring system, the best irrigation time for crops, the amount of irrigation water and the water-saving measures to be taken as the main content of the irrigation forecast results are obtained, and the results are regularly released to the masses, and farmers are scientifically guided in real-time and actual irrigation to achieve water saving Purpose.
2. System composition
The system includes: intelligent perception platform, wireless transmission platform, operation and maintenance management platform and application platform.
(1) The intelligent sensing platform includes: soil moisture and soil temperature sensors, and intelligent weather stations (temperature, humidity, rainfall, radiation, wind speed and wind direction).
(2) Transmission network includes: network transmission standard, PAN network, LAN network, WAN network.
(3) The operation and maintenance management platform includes: moisture (drought) forecast, remote irrigation/automatic control, and farmland water conservancy management.
(4) On the application platform, users can receive farmland moisture information and weather information through mobile phones, PDAs, computers and other information terminals, and can remotely control irrigation equipment. For government management departments, the platform can be used to improve the comprehensive management level of agricultural conditions, agrometeorology, and farmland water conservancy.
3. Features and innovation
1) One node can support two-way solenoid valve control and status, and two-way moisture information collection at the same time; the node is easy to install, and the network scale ranges from a few to hundreds, and it is easy and quick to add or move nodes;
2) Integrated water pressure switch status feedback to improve the reliability of the irrigation system;
3) It supports a wide range of solenoid valve product lines, not only supporting solenoid valves from irrigation companies such as Netafim, Rain Bird and Hunter, but also supporting products from famous foreign valve manufacturers Bermad, Dorot and TECHNIDRO;
4) The wireless uses the world’s free public frequency band (2.4GHz), saving traditional wireless operating costs;
5) The system regularly collects network node voltage, working temperature and communication link status to realize network self-diagnosis function;
6) Support the collection of soil moisture, crop condition information and farmland microclimate information. The powerful UniLog management software can estimate the most suitable farmland irrigation time and amount based on the collected meteorological information, and make intelligent management decisions;
7) Support supplementary irrigation and rotation irrigation modes to meet the irrigation needs of different users;
8) The management software integrates GPRS/GSM technology, supports smart alarm based on SMS, and supports remote management based on Internet.
