列车运行监控记录装置测试设备检定装置的测量不确定度评定

摘要

列车运行监控记录装置准确、稳定、可靠地使用直接关系到列车运行安全,列车运行监控记录装置测试设备的量值准确与否直接关系到列车运行监控记录装置的检修质量。通过对列车运行监控记录装置测试设备检定装置的模拟机车速度、模拟柴油机转速、模拟列车管压力、模拟双针速度表速度、速度传感器测试台速度等主要指标的测量不确定度评定,确定各指标的测量方法能够保证量值传递的准确、可靠。%The accurate,stable,reliable use of the Train Running Monitoring and Recording Equipment is directly related to the safe operation of trains. Whether the value of the test equipment for the Train Running Monitoring and Recording Equipment is accurate is directly related to the quality of calibration and repair of the Train Running Monitoring and Recording Device. By evaluating the measurement uncertainty degrees of the verification device for the test equipment of the Train Running Monitoring and Recording apparatus in the aspects of simulation of locomotive speed, simulation of diesel engine rotation speed,simulation of train pipe pressure,simulation speed value on the double-needle speed meter,speed value of the speed sensor on test stand,etc. the measurement methods for different indicators ensure the accurate and reliable traceability.
