Abstract

The invention discloses a railway truck fault diagnosis system on the basis of power sharing. The railway truck fault diagnosis system comprises N sensors, M main units and connecting circuits. The sensors and / or the main units have power generation functions; the N and the M are positive integers; power sharing ends of the N sensors and power sharing ends of the various main units are communicated with one another via the connecting circuits; the sensors with the power generation functions and / or the main units with the power generation functions are provided with anti-backward assemblies, and the anti-backward assemblies are arranged between output ends of power generation assemblies of the sensors with the power generation functions and / or the main units with the power generation functions and the power sharing ends of the sensors with the power generation functions and / or the main units with the power generation functions; local energy dissipation circuits are connected with the power sharing ends of the sensors and the main units. The railway truck fault diagnosis system has the advantages that the various sensors and the main units can keep in relatively stable voltage statesto work by the aid of power sharing between the various internal sensors, between the sensors and the main units and between the main units, and accordingly the power generation stability and the reliability of devices can be improved.

Description

Technical field

[0001] The invention relates to the technical field of detection of transportation equipment, in particular to a railway freight car fault diagnosis system based on power sharing. Background technique

[0002] With the rapid development of China's railway freight transport in the direction of heavy load and speed, higher requirements have been placed on the transportation safety of railway freight cars. In order to ensure the transportation safety of railway freight cars, fault diagnosis devices need to be used to monitor and diagnose freight cars online. The fault diagnosis device is installed on the truck and consists of sensors, host and connecting cables. However, because the railway freight car is not charged except for the head of the railway freight car, the fault diagnosis device installed in the vehicle cannot work by connecting to the power supply of the vehicle. Therefore, the fault diagnosis device is needed to solve the self-powered problem.
