Abstract
Description
Technical Field
[0001] This application relates to the field of data acquisition, and in particular to a vibration data acquisition and verification device. Background Technology
[0002] Currently, most vibration data acquisition devices on the market have their sensors located in the same position on the train axle box, using only one sensor to collect vibration data. However, this configuration has certain drawbacks. During high-speed train operation, vibration signals may be affected by external factors such as track unevenness or other interference, leading to errors or false alarms in the collected signals. For example, when a train travels through an uneven track area, it may generate vibration signals similar to those of an axle box malfunction. With traditional single-sensor systems, such errors are difficult to effectively identify and eliminate, potentially causing unnecessary emergency braking due to false alarms, thus affecting train safety and operational efficiency.
[0003] To improve the accuracy and reliability of vibration signal acquisition, dual-channel acquisition technology has emerged. This involves installing multiple sensors near the axle box to collect data and then cross-verifying it to avoid false alarms caused by interference or errors from a single sensor. Although some high-end devices are attempting to implement multi-sensor redundancy configurations, most devices still fail to effectively solve the problem of false alarms, especially in complex environments (such as uneven tracks). Therefore, there is an urgent need for a new vibration data acquisition and verification device that can accurately determine the authenticity of axle box vibration signals by using multi-sensor, multi-signal redundant acquisition, and radio frequency signal transmission technology for real-time data comparison, thereby avoiding false alarms and unnecessary emergency braking.

[0023] Vibration signal acquisition board 1 is used to acquire acceleration signals from vibration sensors installed on the train axle box, convert the acquired analog signals into digital signals, and send them to the radio frequency signal transmission board in real time via Ethernet TCP protocol; Vibration signal acquisition board 2 is used to acquire acceleration signals from another vibration sensor installed on the train axle box, convert the acquired analog signals into digital signals, and send them to the radio frequency signal transmission board in real time via Ethernet TCP protocol; the installation positions of vibration signal acquisition board 1 and vibration signal acquisition board 2 are no more than 3 cm apart, and each acquisition point is redundantly acquired by sensors from vibration signal acquisition board 1 and vibration signal acquisition board 2 to ensure data accuracy and redundancy backup.
[0024] Vibration signal acquisition board 1 and vibration signal acquisition board 2 are installed at each axle box of the train. Both boards are connected to vibration sensors. The acquired vibration signals are converted into digital signals and then transmitted in real time to the radio frequency signal transmission board via Ethernet TCP protocol. The installation positions of the two acquisition boards are no more than 3 centimeters apart, ensuring the accuracy of redundantly acquired data.
[0025] The device uses dual-channel acquisition technology to ensure redundant backup of vibration signals. Even if one sensor fails or is interfered with, the other sensor can still provide accurate data, improving the reliability and accuracy of the data and avoiding false alarms caused by a single sensor failure.
[0026] Example 2
[0027] Vibration signal acquisition board 1 and vibration signal acquisition board 2 are respectively connected to the corresponding vibration sensors, and the acceleration sensors of vibration signal acquisition board 1 and vibration signal acquisition board 2 are independently installed on the two axle boxes of the train. The acquired signals are converted and transmitted through their respective digital signal processing modules.
[0028] Vibration signal acquisition board 1 and vibration signal acquisition board 2 are installed on the front and rear axle boxes of the train and are connected to vibration sensors respectively. The acquired acceleration signals are converted and processed by the digital signal processing module, and then transmitted to the back-end data processing system via the Ethernet TCP protocol.
[0029] Since the two acquisition boards are installed on different axle boxes of the train, independent acquisition and redundant verification of vibration signals from various parts of the train can be achieved, ensuring the comprehensiveness and accuracy of data acquisition, thereby improving the overall vibration monitoring capability of the train.

It also sends the data to the radio frequency signal verification board through antenna 1 and antenna 2 for further signal transmission and verification.
[0032] The radio frequency (RF) signal transmission board connects vibration signal acquisition board 1 and vibration signal acquisition board 2. The acquired vibration data is transmitted to antennas 1 and 2 via this transmission board, and further transmitted to the RF signal verification board via RF signals.

It enables timely and accurate diagnosis of fault locations, prevents false alarms, and allows for targeted repairs or interventions.

[0040] The RF signal verification board receives data from the RF signal transmission board in real time and verifies the integrity and accuracy of the received data. If the signal is lost or interfered with, it will issue a warning in time and retransmit the data.
[0041] This verification mechanism ensures high stability and accuracy during data transmission, effectively preventing data errors caused by signal loss or interference, and improving system reliability.
[0042] Example 6
[0043] The radio frequency signal verification board compares the vibration signals of the front and rear carriages of the train in real time to determine whether the abnormal vibration signal is caused by uneven track, and feeds the result back to the data processing system for further fault confirmation and alarm.
[0044] The radio frequency signal verification board compares the vibration signals of the front and rear carriages of the train in real time. When the train passes over uneven tracks, the verification board will automatically identify and eliminate false alarms caused by track unevenness, and feed back the eliminated data to the data processing system.
[0045] This embodiment effectively distinguishes between vibrations caused by track unevenness and vibrations caused by axle box malfunctions, reducing false alarms and ensuring high system accuracy.
