The network consists of convergent nodes, routing nodes, multi-path environment parameter acquisition nodes and device control nodes. Wireless transmission mode is adopted between the nodes to realize the sending and receiving, processing, storing and controlling of greenhouse environment multi-path parameter information, which solves the high cost of artificial wiring and the difficulty of maintenance of greenhouse environment measurement and control system. A series of problems such as poor extensibility and so on. Research and development of a greenhouse environmental parameters multi-way measurement and control device. The device chooses CC2591 chip, multi-channel environmental parameter acquisition device and control equipment as the main modules, and designs the related peripheral interface circuit of CC2530 chip, and completes the hardware development of various network nodes in the multi-channel measurement and control system. The production cost is reduced, the development cycle is shortened, and the multi-channel acquisition of greenhouse environmental parameters and the control of greenhouse equipment are realized. The application software of various network nodes in multi-channel measurement and control system is designed. Based on the analysis and research of Z-Stack protocol stack, combined with the system requirement and hardware design, the system network communication protocol is customized, and the low power dormancy mechanism of node core chip CC2530 and the finite state machine flow control mode are used. The related application programs of all kinds of nodes, greenhouse control center and upper computer software are developed to ensure the stability of the system and the reliability of data transmission. The test results show that the system has the functions of automatic networking, data receiving and sending, storage and management, multi-channel environmental parameter acquisition and multi-channel equipment control, etc. At the same time, the reliability of the system network data transmission is high. It meets the demand of wireless and intelligent management of field environmental parameters in greenhouse agricultural production process, and has important practical significance to improve the level of greenhouse agricultural management.
