[0090] The axle temperature remote monitoring system of the self-wheel running special equipment of the embodiment can transmit the wheelset axle temperature, gear box temperature, and environmental temperature data collected by the axle temperature monitoring unit to the ground integrated management platform in real time through a wireless network (mobile network 4G, 5G), and the user terminal display can display the above information of each vehicle in real time. The terminal user can search and remotely download temperature record data according to the track car number, time, etc., and the download interface can be as shown in Figure 7 When the self-wheel running special equipment is online, the temperature data and other information can be transmitted back to the server and the user terminal of the test center in real time. For historical temperature data that has not been transmitted, it can be transmitted back according to the user's selection, or it can be transmitted back periodically and automatically.

[0091] The ground integrated management platform of the self-wheel running special equipment of the embodiment can analyze the temperature data transmitted back by the data transmission unit (GMS). For example, based on environmental temperature, running speed, line condition (judging uphill and downhill according to slope information), whether braking, etc., it can be judged whether the real-time axle temperature at the same time is within the normal value range. Based on environmental temperature, running speed, working time, etc., it can be judged whether the real-time gear box temperature at the same time is within the normal value range. When the axle temperature and / or the gear box temperature is in the abnormal value range, the vehicle management department is prompted to repair the vehicle in time.

[0092] For example, if the current environment temperature of the rail car is 30 degrees, and the axle end or gear box temperature has exceeded a certain value when the motor car is not running, it is considered that the temperature of the axle or gear box of the rail car is abnormal, and a warning is proposed; and if the axle end or gear box temperature is higher than the environment temperature by a certain range for a long time running in the uphill or downhill state, it can be considered as a normal situation.

[0093] Through the ground management platform, the running state and temperature data of the vehicle are comprehensively analyzed in combination with the vehicle running working condition information (speed, mileage, line), the working temperature of the bearing, gear box and the like of the vehicle is comprehensively analyzed and judged, the abnormal state is found early, maintenance is performed early, hidden troubles are eliminated, and the driving safety of the self-wheel running equipment is ensured.

[0094] The scheme is based on temperature sensor technology, remote data transmission technology, microprocessor technology, server technology and big data technology, and combines with the GYK rail car running control equipment of the self-wheel running special equipment, realizes remote transmission and real-time monitoring of the temperature data in the running and construction process of the self-wheel running special equipment, is beneficial to timely analyzing the temperature data of the self-wheel running special equipment and eliminating the safety hidden troubles of the vehicle, and ensures the driving safety of the self-wheel running special equipment.
