Superposition system and method of high-speed railway track temperature, beam temperature state temperature and video

Abstract

The invention discloses a system and method for superimposing rail temperature and beam temperature state temperature and video of a high-speed railway, which is suitable for use in high-speed railways. Firstly, the rail temperature and beam temperature are measured by wireless temperature sensor, and the temperature information is stored in the character storage module wirelessly to complete the serial communication between the character storage module and the video character superimposition module; the monitoring camera is used, and the synchronization signal is separated by the synchronization signal separation circuit. It is a line synchronization signal and a field synchronization signal, and at the same time, the video signal is amplified by the amplifying buffer circuit and transmitted to the video character superimposing module. Superimpose, and transmit the video and character superimposition to the display module for superimposition display. It is based on the superposition of digital signals, the superposition effect is flexible, and it has strong programmability and expansibility, which can realize more precise superposition control according to product requirements.

Description

technical field [0001] The invention relates to a superimposition system and method of state temperature and video, and is especially suitable for a superimposition system and method of state temperature and video of high-speed railway track temperature and beam temperature used on high-speed railway. Background technique [0002] China's high-speed rail is an important part of my country's transportation industry, and high-speed rail has played a very important role in promoting the development of China's industrialization and urbanization, and represents my country's advanced technology level. [0003] High-speed railway requires the line to have the characteristics of high smoothness, high precision, less maintenance and small residual deformation, and temperature effect is one of the main factors affecting the high smoothness and stability of high-speed railway box girder-track system. The temperature of the infrastructure is an important factor determining the stability...

Problems solved by technology

[0004] In the patent CN201657208U, a new type of video anti-counterfeiting circuit board, the video signal has not been amplified and buffered, the video signal will be disturbed by the external environment, and there is a large impedance that causes the video signal to be unstable, and it is difficult to form a stable superimposed video character signal. On the one hand, the superimposed video character signal has two transmission directions, which greatly affects the efficiency and security of transmission; in the patent CN110445995A, a UAV video superimposition system mainly adopts a software superimposition system, and the characters of the video character superposition module Generally, the library can only recognize ASCII codes. This patent does not convert the character information to be converted into ASCII code values. On the other hand, it uses software superposition. Mistakes will make it difficult to find mistakes, and the repair process will affect the safety of the train, which is far less secure and adaptable than the combination of hardware systems and programs
