The terminal nodes are mainly configured with various sensors, which are mainly used to collect various data information to obtain the natural growth of crops. Environmental parameters; the routing node is mainly responsible for transferring and routing data, and transmits the data collected by each sensor to the coordinator node; the coordinator node mainly serves as the controller, is responsible for starting the network, configuring the network address, and transmitting the data to the monitoring center. In the terminal node, the data collection 1 module is used to collect data, and the processor 1 module is responsible for the data communication algorithm, and controls the wireless transceiver 1 module to transmit the data to the wireless transceiver 2 module in Zigbee wireless communication. In the routing node, the processor 2 module performs the communication algorithm and processing algorithm on the data, and controls the wireless transceiver 2 module to transmit it to the wireless transceiver 3 module in Zigbee wireless communication. At the same time, the routing node can also collect data through the data acquisition 2 module. Similarly, the wireless transceiver 2 module transmits to the wireless transceiver 3 module, and the processing 3 module is responsible for the communication algorithm and processing algorithm for these data, and controls the serial communication module to The GPRS network transmits to the monitoring center. The monitoring center makes decisions based on the collected information and controls the switching of irrigation equipment and the amount of irrigation.

[0020] Among them, temperature sensor, humidity sensor, light intensity sensor and rainfall sensor are used to collect temperature, humidity, light intensity and rainfall information respectively. The solar panel is used to provide energy for each node, and is also used to charge the battery so that the battery is used as a backup power source; the charging chip is used to charge the battery by the solar panel. Specifically, when the sunlight is good, the solar panel is used to supply power to each node, and at the same time, the solar panel also charges the battery through the charging chip; when the lighting condition is poor, the battery is used to power each node.

The processor is the core part of each node, responsible for data processing, energy management, software communication protocol and other module work management. In the present invention, S3C2440A is selected as the main control chip of the processor, which has the advantages of low power consumption, strong data processing capability and low cost.

[0023] Preferably, the temperature sensor and the humidity sensor are TYX-CTWS1 soil temperature and humidity sensors. TYX-CTWS1 integrates soil moisture and soil temperature sensors, which can simplify the instrument and facilitate the measurement of soil information. At the same time, it also has the advantages of good stability, low power consumption and long service life.

[0024] Preferably, the light intensity sensor is BH1750. BH1750 has a built-in analog-to-digital converter, which can output digital signals without connecting external components, which greatly reduces power consumption and cost.
