Abstract:

Environmental monitoring sites have the characteristics of wide distribution and multi-points, it has an important role in timely grasping the environmental situation and effectively controlling the spread of environmental pollution by establishing a real-time monitoring and controlling system based on Wireless Sensor Network, and realizing online monitoring of environmental factors within certain regions. The collection and transmission of the parameters of indoor environment in a large range are realized through building a wireless sensor network based on ZigBee communication protocol using CC2530 chip, the collected data are analyzed and processed by the main controller PLC. Monitoring data received are transmitted to the host computer for real-time display through the master coordinator and PLC, remote control of indoor equipment is realized by the monitoring platform, combined with infrared transceiver. WinCC configuration software is used as the host computer, and SIEMENS smart panel is configured to provide an excellent human-computer interaction experience. The experimental results show that, the acquisition and transmission of indoor environment parameters as well as remote monitoring function in a wide area can be achieved by this system. It has the features of convenient installation and strong extensibility, which is suitable for all intelligent buildings which has a need for unified management.
