In order to realize the real-time monitor of tanker vehicles, hazardous goods and environmental conditions, a multi-parameter monitoring system for tanker based on wireless sensor networks is built. A kind of multi-interface wireless sensor nodes is designed, which consists of ultra-low power ATmegal281 microcontroller and AT86RF230 RF module. With the foundation of the deployment for nodes on the tanker, a static clustering routing algorithm is proposed, and the software for nodes is designed by using TinyOS and NesC. Experiment results show that the system can meet the requirement of information collection and monitoring, which results in a wide range, laid convenient, high reliability and low power consumption%为了实现对油罐车罐体、危险品和环境等状态的实时监测,采用无线传感网络技术,构建了油罐车多参数监测系统.本系统以超低功耗的ATmega1281微控制器和AT86RF230射频模块为核心,设计了一种多接口无线传感节点；结合节点在油罐车上的部署方式,提出一种基于静态分簇的路由算法；采用TinyOS操作系统和NesC语言完成节点的软件设计.实验结果表明,该系统能够满足油罐车多种状态的实时采集与监测需求,具有监测范围广、布设方便、可靠性高和功耗低等特点.
