电子巡更系统在狱警管理中的应用

Application of QRA on Prison Guard Management

针对目前出现的狱警管理系统实时性差、数据孤立、数据分析困难等问题,提出了一种基于RS485、CAN和ZigBee三层网络构架的狱警管理巡更系统并设计了信息采集器和数据终端;为保证数据的可靠传输,设计了相应的通信协议。对所设计的系统进行了测试,测试结果表明,系统具有运行稳定、布线简单、网络维护成本低、数据丢包率低、满足监狱安全要求、潜在风险小的特点,达到了设计要求。

In view of the following problems：the backward technology in prison guard management,the poor technology,data iso- lation and data analysis difficult,this paper proposes a three-layer network construction based on RS485,CAN and ZigBee and designed the corresponding hardware of prison guard management.And then,to ensure the reliability of communication, the serial communication protocol is designed.In the end,the designed system is tested,the results show that the system had many advantages,such as high reliability,simple wiring,low cost,Network maintenance cost low,data frame loss rate low, satisfying prison safety requirements,potential risk low,and satisfies the design requirements basically.
