ZigBee技术在重大危险源实时监测预警系统中的应用

Application of ZigBee technology in pre-Alarm system for major hazard installations

ZigBee作为一种低速率、低成本、低功耗、组网简易灵活的短程无线网络协议,特别适合目前的重大危险源监测预警领域。通过它,可以在确保数据传输可靠性和实时性的前提下,大大提高重大危险源监测预警系统前端的可扩展性,从而降低系统建设和设备维护的成本。本文有针对性的提出了采用ZigBee无线通信技术构建重大危险源监测预警系统无线传感器网络,详细分析了ZigBee网络的构建为重大危险源监测预警系统起到的作用,并在实践中验证了该方案的有效。

As a short distance radio network, ZigBee is especially suitable for major hazard installations pre-alarm system depending on its low bit rate, low cost, low power and flexible networking. At the condition of transforming data＇s reliability and real-time, ZigBee network increases the flexibility of the pre-alarm system＇s front end mostly. Consequently, the cost of the pre-alarm system and its maintaining become very low. In this article, the design of wireless sensor system by using ZigBee for Pre-Alarm System of major hazard installations was brought forward pertinently. Meanwhile, the functionality of the ZigBee in the Pre-Alarm System was analyzed in detail. The scheme＇s validity was also verified in practice.
