Design on Remote Monitoring System for Mobile Hazardous Chemicals Based on MEMS Technology

摘要:

目前危化品运输监测体系不够完善,同时事故的预防和处理对人力依赖过度,监测效果不尽如人意；为了最大程度上减轻危化品泄露事故危害,设计了一种基于无线通讯和卫星通讯系统的移动危化品远程监测系统；利用车体不同位置安放的各种MEMS传感器及时地获取运输信息(如气体泄漏情况、速度、加速度、温度、湿度及倾角等),采用ZigBee技术传输至移动端中央处理器,并通过GSM向监控端进行反馈,从而对监测到的异常情况做出迅速反应；经过实际测试,测试结果满足精度要求,有效的解决了移动危化品的在线监测和定位。

Abstract:

Currently, since the monitoring system of hazardous chemicals transportation is imperfect while the prevention and treatment of accident excessively depends heavily on manpower, monitoring effect is not satisfied. To reduce the leak harm at best, a remote monitoring system for mobile hazardous chemicals based on wireless communications and mobile satellite communications systems is designed. Various MEMS sensors of data acquisition module are placed around the vehicle to obtain transport information timely(such as gas leakage, speed, acceleration, temperature, humidity, tilt angle, etc.) , while ZigBee is used to transmit the information to the central processor of mobile end, and GSM to feedback to the monitoring side, thereby rapid response can be taken when abnormality is tested. Experimental results show that the test results meet the precision requirements. The online monitor and position of mobile hazardous chemical is solved effectively.
