摘要
针对城市井盖经常被损坏或者盗窃,危害到城市群众的安全,提出利用压电供能的井盖安全监控系统设计。本系统将嵌入式压电装置安装在井盖上,利用汽车和行人碾压井盖产生电能,解决了传统系统电池更换困难的问题。通过采用分布式的低功耗Zig Bee技术,每个井盖作为ZigBee的分布节点,多个节点组成网状拓扑结构,最终将报警信息发送给嵌入式网关。设计嵌入式网关进行数据存储和管理,实时上报各个井盖的安全状况,及时将紧急给监控中心和维修人员,同时ZigBee节点自身产生声光报警,提前解除安全隐患。
Aiming at problem that manhole cover theft and damage,it has caused lots of economic lossesand casualties,propose a design for manhole cover monitoring based on piezoelectric generator.The thepiezoelectric generator can be installed on the manhole cover,to create the power by rolling the manholecover and solve the battery replacement problem.By using low power ZigBee technology,every manholecover has became the distribute node in ZigBee,lots of nodes consists the mesh topology and finally sendthe alarm message to the embedded gateway.At the same time design embedded gateway to store andmanage data,report the real safety situation to the monitor center and maintenance personnel,the ZigBeenode generate the sound and light alarm,and remove hidden dangers in advance.
