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 hazardous gases is important for production safety and public safety. Aiming at the disadvantages of traditional wireless gas monitoring system, such as fixed nodes only result in the simplification of node type, lag of danger and slow elimination of danger, a wireless gas monitoring system with patrolling and locating function is designed. The system is composed of two parts: the lower computer mainly uses ZIGBEE and TGS813 sensor, the upper computer includes the client monitoring software and database service. The system specially designed a flexible mobile patrol hand-held node to solve the traditional gas monitoring system lack of flexibility. With low-cost, low power consumption, responsive, high flexibility and so on.
