As mentioned in the background art, the detection of the automatic excessive phase signal processor in the prior art requires professionals to carry professional equipment to detect the automatic excessive phase signal processors on the train one by one. The reason for this problem is that there is currently a lack of a detection device capable of automatically detecting the automatic over-phase signal processor.

Based on the above reasons, the present invention provides an automatic over-phase signal processor detection method and system, which simulates various signals received by the automatic over-phase signal processor during the running process of the train.

Step S120, if the standard feedback signal of at least one test signal of the same performance to be detected is different from the actual feedback signal corresponding to the test signal, it is determined that the performance to be detected of the automatic over-phase signal processor is not up to standard.

In this embodiment, by sending a variety of test signals corresponding to the performance to be detected to the automatic over-phase signal processor, the actual feedback signal output by the automatic over-phase signal processor after receiving each test signal is obtained. The performance to be detected includes the automatic over-phase of the automatic over-phase signal processor, the identification of signal defects and the elimination of interference signals. Then the received actual feedback signal is compared with the standard feedback signal corresponding to each test signal of the transmitted performance to be tested. If the actual feedback signal is the same as the standard feedback signal, it is determined that the automatic over-phase signal processor needs to be The detection performance is up to standard. If the standard feedback signal corresponding to at least one test signal in the performance to be detected is different from the actual feedback signal, it is determined that the performance to be detected of the automatic over-phase signal processor does not meet the standard. Through the above device, it is possible to simulate various signals received by the automatic over-phase signal processor during the actual operation of the train.

Exemplarily, when the running speed of the locomotive is greater than the speed threshold, the advance ground positioning signal, the forced ground positioning signal and the closing ground positioning signal are pulse signals between 4.3V-5.1V and 4-8ms.

Exemplarily, when the running speed of the locomotive is less than or equal to the speed threshold, the advance notice ground positioning signal, the forced ground positioning signal and the closing ground positioning signal are pulse signals of 2.1V-2.6V and between 9-14ms.

In this embodiment, by simulating the advance ground positioning signal, the forced ground positioning signal and the closing ground positioning signal sequentially sent to the automatic over-phase signal processor by the locomotive in the fast running state, it is detected that the automatic over-phase signal processor is in a fast running state of the locomotive. Whether the performance in the running state is up to standard.

Exemplarily, if the amplitudes of the advance ground positioning signal, the forced ground positioning signal and the closing ground positioning signal are 2.1V-2.6V during low-speed operation, and 4.3V-5.1V during high-speed operation. Then, the amplitude of at least one of the advance ground positioning signal, the forced ground positioning signal and the closing ground positioning signal is 2.1V during low-speed operation and 4.3V during high-speed operation.

In this embodiment, whether the sensitivity of the automatic over-phase signal processor is up to standard is tested by sending a test signal whose amplitude is the lower limit value of the over-phase signal processor to the automatic over-phase signal processor. No reacts to the lowest amplitude test signal.

In one embodiment, the standard feedback signal of the advance ground positioning signal is an over-phase advance disconnection signal, the standard feedback signal of the forced ground positioning signal is an over-phase forced disconnection signal, the standard feedback signal of the closing ground positioning signal is a recovery signal, and the interference The standard feedback signal for the signal is no signal.

Exemplarily, the standard feedback signal is a signal with a pulse width between 900ms-1100ms.

Exemplarily, the detection device starts timing when the test signal is sent, and if there is no feedback signal within a preset time, it means that the standard feedback signal is no signal.

In this embodiment, by setting corresponding standard feedback signals for the advance notice ground positioning signal, the forced ground positioning signal, the closing ground positioning signal and the interference signal, it is possible to set the standard for determining whether the automatic over-phase signal processor meets the standard, so that the The detection device can judge whether the automatic over-phase signal processor meets the standard according to the standard feedback signal.

In practice, the automatic out-of-phase signal processor recognizes the signal sent by the sensor set on the rail to determine whether the locomotive has reached the out-of-phase point. Therefore, when adjusting the locomotive direction of the locomotive, it is necessary to send a signal to the automatic over-phase signal processor, so that the automatic over-phase signal processor obtains the forward direction of the locomotive, and then adjusts the determination of the sequence of received signals. For example, as shown in Figure 4, when the locomotive moves from left to right, it sends a pre-announced ground positioning signal to the automatic over-phase signal processor at point G1, sends a forced ground positioning signal to the automatic over-phase signal processor at point G2, and at G3 Send the closing ground positioning signal to the automatic over-phase signal processor.
