摘要
矿用气体传感器因煤矿安全被大量使用,国家规定必须定期进行调校,目前的传感器调校系统可同时对5-8台传感器进行调校,针对大中型煤矿生产过程中需要调校的矿用气体传感器数量大、调校耗时长的现状,提出了一种基于单片机与现场可编程门阵列（FPGA）的64路气体传感器调校系统,介绍了系统的整体设计并详细阐述了该系统的气路控制模块和传感器输出信号采集模块,使用Verilog语言在QuartusⅡ工具中实现FPGA的逻辑设计、仿真和综合。结果证明：该系统能有效地完成对64路气体传感器同时调校的目的,很大程度节省了人力消耗,提高了调校效率,节约了调校时间。
Gas sensor is widely used for coal mine safety, and according to national regulation, it must be adjusted regularly, current gas sensor calibrator system can detect 5- 8 sets of sensor at the same time, aiming at status of large amount of coal mine gas sensor and long time needed to be adjusted in large and medium-sized coal mine production process, a kind of adjusting system for 64 channels gas sensor based on MCU and FPGA is studied,overall design of the system is described and air path control module and module of output signal acquisition of sensor are expounded in detail. Verilog language is used in Quartus Ⅱ tool to implement logic design, simulation and synthesis of FPGA. The results show that the system can efficiently completes calibration of 64 channels gas sensor at the same time, greatly save manpower improves working efficiency and saves working time.
