Abstract

The invention discloses a railway freight car fault diagnosis system based on power supply sharing, which includes: N sensors, M hosts and connecting circuits; wherein, several sensors and / or several hosts have power generation functions; N and M are positive Integer; the power sharing end of each sensor and the power sharing end of each host are connected to each other through the connecting circuit; the sensors with power generation function and / or the host include anti-reverse components, and the anti-reverse components are set on the sensors with power generation function and / or between the output end of the power generation component of the host and the power sharing end; both the sensor and the power sharing end of the host are connected to their own energy-consuming circuits. The present invention enables each sensor and the host to maintain a relatively stable voltage state for work through power sharing among the internal sensors, between the sensor and the host, and between the hosts, thereby improving power generation stability and device reliability.

Description

technical field

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

[0002] With the rapid development of China's railway freight in the direction of heavy load and speed, higher requirements have been put forward for the transportation safety of railway freight cars. In order to ensure the transportation safety of railway wagons, it is necessary to use a fault diagnosis device to monitor and diagnose the wagons online. The fault diagnosis device is installed on the truck vehicle and consists of sensors, host and connecting cables. However, since the carriages of railway freight cars are not electrified except for the headstock, the fault diagnosis devices installed in the carriages cannot work by connecting to the power supply of the carriages. Therefore, fault diagnosis devices are needed to solve the problem of self-power suppl...
