新型煤矿盘形闸检测仪的研制

摘要

针对现有煤矿盘形闸检测仪数据存储量小且无通信功能的问题,提出了一种基于μPSD3354微处理器和模数转换芯片ADS7957的新型盘形闸检测仪设计方案.该检测仪能够自动检测并实时显示盘形闸的工作状态参数,当盘形闸的间隙超出规定值时能够进行声光报警并显示超限闸；可存储约1 a的检测数据,并能将存储的历史数据发送至上位机.测试结果表明,该检测仪性能稳定可靠.%In order to solve problems of few stored data and lack of communication function of existing detectors of disk brake in coal mine, the paper proposed a design scheme of novel detector of disk brake based on μPSD3354 microprocessor and ADS7957 A/D chip. The detector can automatically detect and real-timely display parameters of working status of disk brakes. When brake clearance exceeds the specified value, the detector will give sound and light alarm and show the exceeding brake. Besides, the detector can store data detected in a year, and transmit the historic data to upper computer. The testing result showed that the detector runs stably and reliably.
