Diagnostic device for locomotive abnormal signal

The invention relates to a diagnostic device, in particular to a diagnostic device for a locomotive abnormal signal.

Locomotives are the most common means of transportation in China. The locomotive knights that are visible from time to time can be corroborated. Relatively because of the large number of locomotives in China, the locomotive failure rate is relatively higher than that of ordinary vehicles. The visible locomotive line can be corroborated.

Because there are many locomotive components and the wide range of technical fields involved, in general, the Cavaliers will overhaul the faulty locomotives by the locomotives when the cause of the fault is unknown. The locomotive technicians use their own repair experience to infer the cause of the fault and carry out maintenance. However, each technician's experience and care are different. Therefore, the judgment of the cause of the malfunction is also different, resulting in different maintenance results. It is more likely that the rider will spend a considerable amount of maintenance costs after the locomotive. The main cause of the failure has not been improved.

Referring to FIG. 1 , in order to improve the above situation, a fault lamp 11 is additionally added to the locomotive dashboard 1 , and different flashing states of the fault light 11 correspond to different fault modes, so that the knight and the technician can observe the fault light 11 . The flashing condition can infer the fault mode to facilitate the maintenance work. However, the blinking condition of the fault light 11 is quite difficult to observe, and each person's concentration and memory ability are different. The interpretation of the flashing condition of the fault light 11 is easy to occur, and different people have different interpretation results. The situation is therefore inconvenient in practical applications.

In order to improve the above shortcomings, another industry has proposed to use the computer to read the electronic control unit (ECU) information of the locomotive to correctly judge the fault shape, so as to improve the accuracy of the interpretation of the fault shape, but the electronic control unit can be read. The information computer is not for everyone, not even for every locomotive, so it is very inconvenient in application.

How to enable the knight or technician to easily and correctly interpret the fault pattern has become a goal of positive improvement for the relevant industry.

Accordingly, it is an object of the present invention to provide a diagnostic apparatus that facilitates and corrects locomotive abnormality signals.
