Embodiment Construction
[0043] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0044] like figure 1 As shown, the roller body test platform for the commutator of the subway, which includes
[0045] Thermocouple 23, microwave collecting equipment 25, microwave receiving equipment 27 and surface processor 29;
[0046] The thermocouple 23 is used to be arranged on the roller body 42 of the commutator of the subway to detect the temperature value of the roller body 42 of the commutator; the microwave collection device 25 is connected to the thermocouple 23 for collecting the thermocouple 23 Incoming temperature data and perform microwave transfer. The microwave receiving device 27 is arranged beside the railroad track, and is used for receiving the temperature value data when the microwave collecting device 25 passes by; the surface processor 29 is connected with the microwave receiving device 27 for receiving the temperature value ...

A roller body test platform for a subway commutator comprises a thermocouple, a microwave collection device, a microwave receiving device and a ground surface processor. The thermocouple is arranged on a roller body of the subway commutator and used for detecting the temperature value of the roller body of the commutator. The microwave collection device is connected with the thermocouple and is used for collecting temperature value data transmitted by the thermocouple and executing microwave transmission; the microwave receiving device is arranged beside the rail and is used for receiving temperature value data when the microwave collecting device passes by; the earth surface processor is connected with microwave receiving device and used for receiving temperature value data and transmitting the temperature value data to the microcomputer. In combination with other structures, the defects that based on technologies of the prior art, a monitoring element is often interfered by an external area in a roller temperature monitoring mode of the subway commutator,, a monitoring place is affected by subway shaking, limiting is not facilitated, and the monitoring accuracy is low are effectively overcome.
Description
technical field [0001] The invention belongs to the technical field of subways, and also belongs to the technical field of roller bodies of commutators, and in particular relates to a roller body testing platform for commutators of subways. Background technique [0002] With the advancement of induction monitoring methods, it is widely used in all walks of life; here, during the operation of the rail subway, the subway car and the rail continue to collide and vibrate, which will make every part of the subway car and the commutator The roller body shows signs of heating up. When the roller body of the commutator is damaged or damaged, the abnormal temperature rise increases, and the roller body of the commutator will often be deformed or unable to rotate, which is not conducive to the correct driving of the subway car; Even the roller attachments that can form the commutator of the subway car are broken, causing serious losses. [0003] At present, the roll temperature monit...
