The invention discloses a real-time track parameter detection system and method. The system carries a Linux operating system in a main processor of dual processors to replace a conventional bare computer for development, and compared with a conventional static detection device, the system provided by the invention is more convenient for the cooperative development of a plurality of persons. Meanwhile, the data throughput and reliability of the system are improved by utilizing a multi-serial-port channel and a multi-thread mode, so that the operation efficiency of the system is improved; in order to solve the problem of poor real-time acquisition performance of the Linux operating system, high-frequency track parameters are acquired through a slave processor in the dual processors, so thatthe real-time performance of the system is ensured; in addition, the system is of a dual-processor architecture, so that rich external interfaces can be provided, and the expansion capability of the system is enhanced; and therefore, the technical problems that an existing track parameter detection system cannot give consideration to high operation efficiency, easy expansion and low cost at the same time are solved.
Description
technical field [0001] The present application relates to the technical field of detection, in particular to a system and method for real-time detection of orbital parameters. Background technique [0002] Track is the basis of railway transportation, and the safety of train operation mainly depends on the smoothness of the railway. Therefore, in order to maintain the safety, comfort and stability of the railway transportation process, it is necessary to maintain the basic smoothness of the track. The detection of track parameters is the main basis for obtaining track status, track changes and analyzing track ill-conditions. [0003] At present, there are two ways to detect orbital parameters: static detection and dynamic detection. The static inspection device is a light rail inspection instrument. The rail inspection instrument system samples the single-chip microcomputer architecture for bare-metal development. Although the cost is low, it has defects such as low operati...
