The signal acquisition device 20 is connected to a sensor 11 provided on the train traction motor 10, and is configured to collect equipment operation data fed back by the sensor 11;

In order to measure the equipment operation data of the train traction motor in all aspects, various sensors such as acceleration sensors, voltage sensors, current sensors, speed sensors, and temperature sensors can be set. According to the actual model of the train traction motor, it can be flexible. A number of different types of sensors are selected to collect equipment operating data for train traction motors. In order to receive data collected by various types of sensors, it can be implemented by multiple sub-signal acquisition boards or setting up multiple signal acquisition channels on a large signal acquisition board.

Further, the raw device operation data collected by the sensor may have a problem of inconspicuous features. Therefore, it may also be pre-processed including signal processing, anti-aliasing processing, amplification, reduction, etc. The pre-processed equipment operating data can better reflect the characteristics and failure points, while reducing the proportion of unnecessary partial signals. Furthermore, since a group of high-speed rail trains requires a large number of train traction motors, and each type of traction motor will have different types of sensors installed, in order to synchronize the equipment operation data and For fast processing, FPGA heterogeneous acceleration function can also be introduced, that is, the hardware acceleration function brought about by the special structure of FPGA can be used to synchronize the bus clock and message synchronization, so as to realize the collection and processing of the collected device operation data in multiple channels at the same time.

For an implementation including, but not limited to, the signal acquisition device shown in FIG. 2:

The signal conditioning circuit 21 is connected to the sensor 11 and is configured to perform preprocessing and anti-aliasing filtering on the received device operation data to obtain processed data;

The input terminal of the analog-to-digital converter 22 is connected to the output terminal of the signal conditioning circuit 21, and the output terminal is connected to the input terminal of the FPGA information acquisition board 23, and is used to convert the processed data which is an analog quantity into a digital quantity;

FPGA data acquisition acceleration board 23, the output end is connected to the input end of the train PHM diagnostic device 30, and is used for multi-channel synchronous data acquisition and processing using the heterogeneous acceleration function of FPGA;

The device operation data recording module 24 is connected to the FPGA data acquisition acceleration board 23 and is used to record and store the device operation data as a digital quantity.

Among them, the PHM standard data stores equipment operation data and characteristic data of various types of occurrences during the full life cycle of the train traction motor 10. These data can be based on aging tests or placed in life testing machines to simulate real working conditions as much as possible. Obtained from the situation, the data is complete, including the omen before each fault, the actual occurrence, mild, moderate, severe, and completely scrapped, and the PHM standard is finally summarized based on the characteristics of the operating data of each stage. Data, therefore, with the support of a certain algorithm, the current operating status of the traction motor 10 can be determined based on the similarity of the characteristics by comparing with the actual operating data of the equipment collected, including whether a fault has occurred and whether it may cause some Symptom characteristics of the fault, the occurrence of the fault, the traction motor can continue to use for a long time or continue to drive without causing a safety fault and other diagnostic results.

From the user's perspective, the formed disk group is like a hard disk, and users can partition, format, etc. . In short, the operation of the disk array is exactly the same as a single hard disk. The difference is that the storage speed of the disk array is much higher than that of a single hard disk, and it can provide automatic data backup. The function of data backup is that once user data is damaged, the backup information can be used to restore the damaged data, thereby ensuring the security of user data.

On this basis, a data transmission interface that is connected to the output of the train PHM diagnostic device 30 through one end and connected to the train information display system through the train bus at the other end will be obtained after diagnosis based on equipment operating data and standard PHM data. The diagnosis result of the train traction motor is sent to the train information display system, so that the train management personnel can monitor the running status and diagnosis result of the traction motor from the train information display system in time.

Further, a diagnosis result judging device connected to the train PHM diagnosis device 30 may be provided, which may determine the current failure level of the train traction motor 10 according to the received diagnosis result of the train traction motor, and when the current failure level exceeds a preset level , Generate fault early warning signals, can assist train managers to monitor high-risk faults.

Based on the 3U standard chassis and function board configuration, it can flexibly implement one-to-one, one-to-two, one-to-three, or one-to-four fault diagnosis and early warning functions of on-board PHM equipment and train traction motors. Conducive to the realization of anti-vibration, heat dissipation and other functions. .
