列车测速仪标准装置传感器检查器

The Check Unit of the Standard Device of the Train Speed Indicator

列车测速仪标准装置传感器检查器是用于对列车测速仪传感器的检测。传感器是列车测速仪的取样部分，而作为取样的传感器，其误差大小直接影响到列车测速仪测速的准确程度。本文介绍了传感器检查器的设计思路及检测方法。

The check unit of the standard device of the train speed indicator is used to check the sensor of the train speed indicator. The sensor is the sample part of the train speed indicator. Being used for getting samples, the error of the sensor affects the accuracy of the result from the train speed indicator directly. This thesis discusses the designing thought and checking method of the check unit of the sensor.
