摘要
危险气体的有效监测对生产安全和公共安全是十分重要的。针对传统的无线气体监测系统通常只设置固定节点导致节点类型单一化,发现险情滞后和险情排除速度慢等缺点,设计了一种具备巡逻和区域定位功能的无线气体监测系统。系统由两部分组成:下位机主要使用ZIGBEE并结合TGS813传感器,上位机包括客户端监控软件及数据库服务。系统特别设计了可灵活移动的巡逻员手持节点以解决传统气体监测系统灵活性的不足。具备低成本、低功耗、响应及时、灵活性高等特点。
Effective monitoring of dangerous gas is very important for production safety and public security.Traditional wireless gas monitoring has the shortcomings of single node type,low sensitivity and slow response. Aiming at these shortcomings,a wireless gas monitoring system with patrol function is proposed in this paper. The system consists of two parts： lower machine is mainly used ZIGBEE with TGS813 sensors;host computer includes client monitoring software and database services. A hand-held mobile patrol node is specially designed to solve the disadvantages of the traditional gas monitoring system. The system possesses the characteristics of low-cost,low-power dissipation,fast response and high flexibility,etc.
