摘要
针对煤矿生产中需要对甲烷气体浓度进行监测的需求,设计一种基于新型氧化锌传感器的矿井气体无线监测系统,介绍氧化锌传感器的特性以及系统的硬件构成。系统主要由传感器、调理电路、数据采集电路、电源模块、显示模块及Zig Bee无线通信模块组成。最后通过试验测试该系统对甲烷气体的监测性能,试验结果表明:该系统可以实现对甲烷气体浓度的有效监测。
A new methane gas monitoring system based on a novel Zn O gas sensor has been designed to meet the need of methane gas monitoring in coal mine. The properties of the sensor and the hardware constitution of the system are introduced in details in this paper. The system is mainly composed of a sensor,control circuit,data acquisition circuit,a power supply module,a display module and a Zig Bee wireless communication module. The monitoring performance of the system was tested in the environment of methane gas. The test results show that this system can monitor the concentration of methane gas efficiently.
