A mode self-adaptive method for rail car fluorescence temperature measurement system and its rail car fluorescence temperature measurement system

Abstract

A mode self-adaptive method for a rail car fluorescent temperature measurement system, which includes two hosts, which are distributed at the front and rear of the train, and is characterized in that: a response communication is adopted between the host and the transfer box, and there is only one The host is in the main control module, and the other host is in the auxiliary mode. The host in the main control mode needs to send a query command to query the data of all the transfer boxes. The host in the auxiliary mode only monitors the data on the bus. The invention realizes the complete self-adaptation of the working modes of the two hosts of the system. When the manual configuration is wrong, the system can identify and correct it, which fundamentally solves the problem of manual misoperation, improves the fault tolerance of the system, and improves the availability and reliability of the system. It also eliminates the need for an external encoder, reducing system complexity and cost.

Description

Technical field [0001] The present invention relates to a rail vehicle fluorescence temperature measuring system. Background technique [0002] The rail car is the main transportation equipment for railway construction, equipment repair, rescue and inspection. With the continuous improvement of railway train operations and further increase in operational density, it is functional, reliability and security for its driving safety equipment. The requirements of sexual aspects are getting higher. The rail axle axle temperature data is an important indicator of driving safety and axle maintenance, and plays a pivotal role in the safe operation of rail cars. Wen Monitoring Alarm Device can prevent major accidents in locomotives, and when the locomotive walks, it can promptly remind drivers to take corresponding measures in time. [0003] The existing axial temperature monitoring system uses a display-host-junction box three-level structure, consisting of a display, host, and temperatur...

AI Technical Summary

Problems solved by technology

The disadvantage of the existing technical solution is that the working modes of the two hosts in the system need to be manually configured. When there is a fault, the system cannot work normally. Moreover, the two hosts are installed at the I-end and II-end of the train, which are far away from each other, so it is not possible to check them manually.
