Abstract
The development of wireless communication promotes the application of wireless sensor network technology in the intelligent agricultural.As one of the key technologies of the IOT, wireless sensor network technology is a good solution in environments where there are more data collection wired communication cabling of complex problems.This design is based on the ZigBee technology of intelligent greenhouse environmental parameters collection is designed for wireless sensor networks.As a new type of wireless communications technology, ZigBee technology is a low power, low data rate wireless communication technologies.
Based on the research of the ZigBee wireless communication technology and wireless sensor network technology, we proposed a design scheme of monitoring system for greenhouse environment parameters based on ZigBee wireless communication technology.Using the CC2530 wireless microcontroller based on 8051 core as hardware core unit design data acquisition hardware circuit node and coordinator node,and use ZigBee wireless communication technology to build a wireless sensor network. With integrated development environment IAR Embedded Workbench, we finish modifying and transplanting ZigBee protocol stack ,coordinator node and terminal node test sample program.We use the CVT-WSN software integrated teaching experiment platform of CVT-IOT-V networking Integrated Laboratory Systems as PC-side Host Computer monitored environmental parameters, and then use CVT-IOT-V networking Integrated Laboratory Systems to simulate some functions test.
Test results showed that the sensor nodes collect data normally , the network sensor node, routing nodes and the coordinator can be composed of normal data transmission, the coordinator node and the PC can communicate with the host computer,the host function display measuring environmental parameters to meet system design requirements.
