High-speed railway temperature information collection and early warning method and system

Abstract

The invention provides a temperature information collection and early warning system for a high speed railway. The system comprises a temperature information collecting device, a current signal / value signal conversion device, a device for dynamically generating a reference threshold of temperature disaster risks, a determining device started by an early warning program, a locating device, a train controlling device for controlling the speed of a train, a storage device and a control device. A control module serves as a core of the whole system, controls operation of the devices on one hand, and is used for being connected with external devices including an external computer device and the like to achieve communication and control. In the system, the dynamic generating mode is adopted in the reference threshold for evaluating the temperature disaster risks, the historical disaster situations are combined, and the historical situations are continuously updated after new early warning is given, so that the risk pre-evaluation of a certain region is considered more completely and scientifically with contrast to historical data. The invention further provides a temperature information collection and early warning method for the high speed railway.

Description

technical field [0001] The invention relates to the technical field of high-speed railway environmental disaster early warning, in particular to a high-speed railway temperature information collection and early warning method and system. Background technique [0002] The rapid development of high-speed railway has become the main force of passenger transport. At present, most of the high-speed railway tracks in our country use seamless steel rails. The seamless steel rails produce various stresses under the influence of external temperature, that is, thermal expansion and contraction. High external temperature may lead to the phenomenon of track swelling. If the outside temperature is low, it is easy to break the rail, so it is particularly important to monitor the temperature of the high-speed railway track. [0003] At present, countries such as Japan, Germany and France, which have developed high-speed railways earlier, have established disaster prevention systems accord...

Problems solved by technology

[0004] The traditional safety assurance method is the manual detection method. This method uses engineers and technicians to inspect the condition of the train tracks on the railway. This manual detection method has low efficiency and poor accuracy.

Later, manual and electronic equipment detection methods appeared, which improved work efficiency, but still required a lot of manpower and material resources, and were not suitable for 24-hour uninterrupted monitoring
