High-speed-train dynamic-stress-test real-time data monitoring system based on GPRS data transmission

Abstract

A high-speed-train dynamic-stress-test real-time data monitoring system based on GPRS data transmission comprises a data acquisition device, a vehicle-mounted computer, terminal equipment and a GPRS data transmission unit. The data acquisition device is used for collecting train dynamic stress test experiment data. An internal portion of the vehicle-mounted computer is provided with data pre-processing and analysis software used for preprocessing collected data signals so as to acquire a parameter and data to be transmitted. The terminal equipment is provided with monitoring and early warning software used for data recording and abnormal early warning, and generating an instruction. The GPRS data transmission unit is used for transmitting the parameter and the data to be transmitted to the terminal equipment, and simultaneously transmitting the instruction of the terminal equipment to the vehicle-mounted computer, wherein the parameter and the data to be transmitted are processed and acquired in the vehicle-mounted computer.

Description

[0001] [technical field] [0002] The application of the present invention relates to a train data transmission system, in particular to a train structural strength and fatigue analysis equipment and a train operating condition monitoring and digital signal processing system. [0003] [Background technique] [0004] The economic development of all countries in the world is inseparable from the development of the transportation industry. Because it is less affected by climate and natural conditions and has a large transportation capacity and single-vehicle load, railway transportation has certain advantages in the regularity and low cost of transportation; The restrictions on weight and volume are unmatched by road and air transportation, so railway transportation plays an important role in my country's economic and social development. After six large-scale speed increases in railway transport from 1997 to 2007, the quality of passenger transport services has been greatly improv...

Problems solved by technology

[0008] (1) The automatic collection device itself can store a large amount of data. Due to road traffic or train scheduling, testers may not be able to download the collected data for several days or even weeks. During this period, the failure of the sensor will not be able to get feedback in time , which will directly affect the quality of the test

If the signal quality of the test does not meet the requirements, it will have a huge impact on later research; if the test is re-tested, the cost of time and money will increase dramatically

[0009] (2) The current dynamic stress data test does not have the function of real-time monitoring, which leads to changes in the service performance of some key parts of the train due to changes in lines, operating conditions, and loss, which aggravates its fatigue damage
