Summary: | The utility model relates to a high-intelligent speedometer for a railway train, which is mainly used for automatically monitoring the passing speed of the railway train and belongs to a microcomputer-control speed measuring device. The utility model is mainly characterized in that two sensors arranged on the outer side of a steel rail receive signals, and the signals are input to a host circuit composed of an SCM, are converted into the train speed through automatic data processing and is also displayed, stored and printed. The speedometer is in the sleep state when waiting the train, the speed measuring result of the train is automatically stored, and the ultraspeed result is automatically alarmed and printed. The utility model solves the problem that a general speedometer has the disadvantages of small speedometer speed measuring range, large power consumption, unsharp display, inconvenient loading and unloading, etc., has no function of storing the speed measuring result and has no automatic fault detection function. |
