摘　　要：无线调车机车信号和监控系统(STP)是有效防止调车作业事故的重要行车安全辅助设备。日常检修实践中,为了降低车载设备无法正常收码及乱码故障,采用衰减器阵列组件测量车载STP设备的接收灵敏度,可以满足测试需求,能够及时检测数传电台的接收机工作状态。The radio signalling and train protection system for shunting locomotive,or STP,is of signicant for train operation safety which can effectively prevent accidents in shunting operation.In routine maintenance,in order to reduce the failure of normal receiving code or receiving false code of on-board equipment,attenuator array is used to measure the receiving sensitivity of on-board STP equipment,which can satisfy the test requirements and detect the working state of the receiver of the digital transmission set in time.
