[Abstract]:Our country is a big agricultural country, but the agricultural development of our country is not ideal, the soil information and the surrounding environment in the field seriously affect the growth of crops, so it is urgent to monitor and change the "four emotions" information in the field. It is imperative for agriculture to enter informatization. This paper takes the field environment of Ye Shengzheng Xinyuan rice industry and Zhongning Qitai Lycium barbarum base as the research object, and dynamically monitors the "four emotions" information in the field through the wireless sensor node. And the information collected by the terminal node is transmitted to the Internet through the coordinator, so that the "four emotions" information in the field can be transformed into information that can be viewed directly. The user can directly send commands through the Internet to control the wireless node to perform related actions. In order to achieve the purpose of agricultural informatization by detecting and changing the environmental information of wireless nodes to the field environment. The following work has been accomplished in this paper: hardware is the basis for the stable operation of wireless node system. The hardware design of this paper is mainly composed of node bottom board and function module. The node bottom board includes power supply circuit which can supply power to the whole node, 485 circuit and USB to TTL circuit which can communicate with the host computer, indicating the power supply situation of the power supply. The signal lamp and buzzer circuit of communication state and fault condition, the power switch circuit of controlling the power supply of function module, the programming interface circuit of writing program to the core module single chip microcomputer, the interface circuit connected with function module; The function module includes the core module for constructing ZigBee network, the module for controlling the switch quantity and the switch quantity and relay module for relays, and the analog and digital input module for various types of sensors. The voltage amplification module that amplifies the sensor outputs the tiny voltage, controls the solenoid valve movement to complete the automatic irrigation motor drive module, the software is the wireless node system realization intellectualized foundation, this paper completes the software design for the coordinator, Software design of router and terminal node. Coordinator software mainly completes ZigBee network construction, communicates with routing node, terminal node and host computer, and router software mainly completes ad hoc network of nodes. The terminal node software design mainly completes the ad hoc network with the router node, receives the data from the sensor and sends the data to the coordinator. Receiving the command from the coordinator to control the action of the related function node. After debugging, the system realizes the stable operation of the wireless node system, and the environmental information collected is basically the same as the actual environmental information. It can send commands to control the action of the solenoid valve and other switch devices, and can realize the intelligent monitoring of the "four emotions" information in the field.
