摘要
接触网悬挂状态检测监测装置(4C)对接触网零部件进行检测,需要接收触发信号。定位触发设备运用激光测距传感器测量得到定位器相对车顶的高度信息,经过编码器脉冲分频、定位器高度自识别、定位器判断、脉宽调制4个环节,实现对接触网悬挂状态检测监测装置相机、光源的精准触发。基于定位触发设备的接触网悬挂状态检测监测装置在某试验基地和运营线路进行现场测试,结果表明:触发信号精准,检测装置可清晰地拍摄出支持装置、吊柱座、接触悬挂等设备照片,照片重复性良好。
Contact line overhead condition inspection and monitoring device（4 C）need to receive triggering signal to inspect the components of contact lines. Using laser ranging sensor to measure the height between locator and car roof, orientation triggering device can accurately trigger the contact line overhead condition inspection camera and light source through encoder pulse frequency, self-recognition of locator, judgement by locator and pulse width modulation. Based on its test data, the device can clearly photograph support device, davit seat, contact suspension with precise signal, and the photos have good repeatability.
