大型装备状态监测无线传感器网络的研究

摘要

In order to solve the reliability of long communication of wireless sensor networks in industrial environment, the optimization design is conducted for its radio receiving circuit. With the multi-channel method based on dynamic distribution, a practical WSN protocol is proposed and implemented. The paper discusses the desigen method of various sensor interface used on the state monitoring of large-scale equipments. The practical results show that,the developed WSN can effectively increase WSN's real-time quality and anti-interference's ability,and satisfy the demand of field testing or working equipment monitoring.%为解决复杂工业环境下无线传感器网络的长距离可靠通信问题,对射频接收电路进行了优化设计.采用动静态分配的多信道方法提出并实现了一种实用的通信协议,还研究了装备状态监测用传感接口的设计方法.通过实际测试,表明所研制的传感器网络实时性和抗干扰性明显提高,能满足大型装备的现场监测要求.
