摘　　要：研制了一款远动模拟传输通道远程环回装置,采用STM32单片机作为主控制器,利用GSM网络,通过继电器组实现厂站端远动模拟传输通道的远程环回。该装置采用动态密码的方式进行身份认证,并配备了独立的监视控制器,用于监视整个装置的运行状态,防止出现通道环回后因GSM网络信号差而无法解环的现象。在巴彦淖尔多个变电站进行测试,装置运行稳定、安全可靠。该装置的投用解决了通道环回需要厂站端有人配合的难题,有助于远动故障的快速判定,节约了维护成本。The development of telemechanical simulation transmission channel remote loop device uses STM32 microcontroller as the main controller. By using GSM network and relay group to realize the remote loop of telemechanical simulation transmission channel in station. The device adopts dynamic password for identity authentication and the dynamic password is transmitted by symmetric encryption. The device is equipped with an independent monitoring controller, which is used to monitor the running state of the entire device, and to prevent the phenomenon that channel loop can not be resolved due to the GSM network bad signal. The device is stable and safe to be tested in several substations of Bayannur. The equipment is used to solve the problem that the loop of the channel needs the manpower′ s cooperation in the station, which is helpful for the rapid determination of remote fault and the saving of maintenance cost.
