TECHNICAL FIELD
[0001] The utility model relates to a turnout monitoring technical field, specifically, a turnout track temperature vibration monitoring device. BACKGROUND
[0002] As the core equipment of the urban rail transit signal system, the turnout occupies the first place in the failure rate in the signal system failure. The state of the turnout is directly linked with the train safety and operation efficiency. Once the turnout fails, the train operation may be hindered, and even a serious safety accident may be caused. Therefore, it is of great significance for the urban rail transit system to ensure the healthy and stable operation of the turnout equipment.
[0003] In the field of turnout monitoring, there are two difficult technical problems. Firstly, the key working condition parameters of the turnout, such as climbing and close adhesion, are easily affected by the track temperature. However, the existing turnout monitoring system mostly uses the air temperature monitoring in the switch machine to replace the track temperature monitoring. Since the air temperature in the switch machine is disturbed by many factors such as the motor operating temperature and the closed condition of the machine body, it cannot accurately reflect the real change of the track temperature, which makes it difficult to timely understand the abnormal change trend of the turnout working condition by means of data. Secondly, the vibration generated when the turnout passes through the train is the most direct reflection of the turnout bed condition. However, the existing monitoring system only collects acceleration parameters and cannot directly provide the vibration frequency and amplitude data which are the focus of the maintenance personnel, resulting in that the turnout vibration monitoring is very one-sided.
[0004] In order to effectively solve the above technical problems, the track temperature vibration monitoring device is born. The device has the ability to monitor the track temperature, vibration frequency and amplitude data of the turnout in real time and online all day round. With the accurate track temperature data, the abnormal turnout working condition can be timely predicted and analyzed. Through comprehensive monitoring of the vibration frequency and amplitude, once the vibration anomaly is caused by the poor turnout bed, the maintenance personnel can be quickly prompted, and then the trend maintenance is achieved, the turnout failure rate is effectively reduced, and the maintenance labor cost is greatly reduced.
[0005] In the prior art, the track temperature vibration monitoring device usually includes temperature sensors, acceleration sensors and data processing modules. These temperature sensors, acceleration sensors and data processing modules are integrated in the same place. However, since the acceleration sensors and data processing modules generate heat during work, the heat will have a negative impact on the accuracy of the temperature sensors, resulting in errors in the track temperature data obtained by the temperature sensors, and then affecting the monitoring accuracy of the whole track temperature vibration monitoring device.
