摘要: 针对现有许多重要的煤矿设备由于非专业人员操作失误存在严重的安全隐患问题,设计了一种煤矿井下IC卡识别开关机装置,介绍了该装置的硬件组成和软件设计。该装置采用非接触IC卡实现身份认证,通过非接触IC卡的读卡判断是否为专业操作人员,根据不同IC卡的权限,发送不同的指令给所控制的防爆开关,执行相应的动作。考虑到煤矿井下应用,还设计应用了防爆外壳与本安电源电路等,保障了该装置的安全运行。Abstract: In view of the problem of serious security risk because a lot of important coal mine equipments were operated by non-professionals, the paper designed an underground IC card identifying on-off device, and introduced hardware constitution and software design of the device. The device adopts non-contact IC card to achieve authentication, uses non-contact IC card reader to judge whether operators are professional, and sends different commands to control explosion-proof switch to perform appropriate action according to different permissions of the different IC card. Taking the application of coal mine into account, explosion-proof enclosure and intrinsical safety power supply circuit were designed in order to ensure safe operation of the device.
