【摘要】 针对地震监控水井,介绍了分布式主从网络化传感器系统的设计。系统底层设计成总线式传感器网络,进行数据的采集与预处理。顶层采用以太网,由中心站处理机通过公用电话网与底层进行通信。考虑到电话网络通信不太可靠的现状,设计了适用于对大量数据进行可靠传输的通信协议,并用Petri网模型对其进行了描述,通过相关分析对其进行了验证。此协议在实际中得到了实现和现场应用,运行效果良好。更多还原

【Abstract】 ;Introduced the design of the distributed sensor network system for monitoring the water well of earthquake forecast.In order to acquire and preprocess sensor data,a sensor network was designed as the bottom layer of the system.At the top layer of the system,an ethernet network was used,in which a central station communicates with the bottom layer through the PSTN.Considering the uncertainty of the PSTN channel,an IRTP communication protocol was specified to transfer a mass of data.A Petri net model was described for the protocol and validated by relevant analysis.The protocol has been successfully put into practical use.更多还原
