【技术实现步骤摘要】
本技术属于煤矿井下电机车安全运行监测系统，具体涉及一种煤矿井下电机车监控装置。
技术介绍
煤矿井下电机车运输系统是煤矿生产中的一个重要环节，电机车运输系统的管理对于煤矿安全生产至关重要。目前，国内一些厂家推出了多种煤矿安全生产的微机监测系统，大多采用红外信号接收技术或开关信号有线传输技术，由于抗干扰能力较差，导致系统的可靠性降低，容易出现误操作，严重影响其在管理系统中的作用。另外，这些系统在使用功能上也有一定的局限性，比如，对矿井电机车运行状态的监测仅限于了解某一区段是否有电机车，却无法了解到具体车辆当前运行的确切位置，无法对电机车进行适时监控，这就使生产调度人员无法对运输车辆进行合理调度，降低了运输效率。国外的一些类似设备虽然采用了先进技术，但由于我国煤矿生产的现实状况不能与之相配套，煤矿企业较少采用国外进口设备。另外进口设备价格昂贵，影响煤矿生产综合成本，难以推广。目前煤矿生产中仍沿用传统的管理办法，这样就存在一些较难避免的事故隐患。
