摘　　要：为避免电力机车异常行为带来的行车风险,提出基于LTE-R无线网络的电力机车运行状态远程检测与自动控制方法。首先采集模块获取电力机车运行状态信号,将其使用信号调理电路转换为优质数字信号后,运用LTE-R无线网络传输到地面监控模块,该模块负责提取所接收数字信号的特征,并依据特征采用长短时记忆神经网络远程检测电力机车运行状态,同时在发生异常行为时通过自动控制发出报警。实验结果表明:不同通信距离下,LTE-R无线网络各通信信道的信号强度均稳定在-6 dBm以上,在准确检测电力机车运行状态的同时,还能完成有效报警。In order to avoid the running risk caused by the abnormal behavior of electric locomotive,a remote detection and automatic control method of electric locomotive running state based on lte-r wireless network is proposed.First,the acquisition module obtains the operation status signal of electric locomotive,converts it into high-quality digital signal using the signal conditioning circuit,and then transmits it to the ground monitoring module using lte-r wireless network.The module is responsible for extracting the characteristics of the received digital signal,and uses the long-term and short-term memory neural network to remotely detect the operation status of electric locomotive according to the characteristics,and sends an alarm through automatic control in case of abnormal behavior.The experimental results show that the signal strength of each communication channel of lte-r wireless network is stable above-6dbm under different communication distances;It can not only detect the running state of electric locomotive accurately,but also complete effective alarm.
