Seamless circuit parameter real time monitoring method based on 'intelligent electron eye'

Abstract

The present invention discloses a seamless line parameter real-time monitoring method based on í‹intelligent electronic eyeíŒ for monitoring railway seamless line parameters. Said method includes the following steps: (1), utilizing camera technique to collect field seamless line image; (2), adopting DSP technique to make image identification treatment to real-time produce seamless line parameter; (3), adopting GSM wireless network transmission technique to transfer the above-mentioned parameter to monitoring centre; and (4), combining field seamless line real-time measured parameter with seamless line management system, and comparing theoretical allowable value with actual measured value so as to implement real-time monitoring control of seamless line parameter and alarm.

Description

Technical field: [0001] The invention relates to a real-time monitoring method, in particular to a method for real-time on-line monitoring and alarming of railway seamless line parameters. The invention belongs to the technical field of railway line detection. Background technique: [0002] With the construction of passenger dedicated lines and the continuous improvement of train speeds, real-time monitoring of seamless line parameters has far-reaching practical significance for protecting traffic safety and preventing accidents. At present, the detection of the parameters of the seamless railway line is done manually, and an observation point is set every two to three hundred meters along the railway line. The detection content includes longitudinal displacement, lateral displacement, displacement between rails, etc. Due to the problems of missed detection, false detection, non-inspection, non-real-time and management problems in manual detection, it is easy to cause pote...

Problems solved by technology

These methods have disadvantages such as insufficient measurement accuracy, inconvenient installation, inability to adapt to vibration and polluted environment, affecting line maintenance operations, high price, and large investment.

[0004] Some people proposed to use video monitoring method, but there are still many problems in using video monitoring to detect the parameters of railway seamless lines: (1) a large number of cables need to be laid, the system cost is large, and the operating cost is high; (2) the video monitoring system is still monitored manually Recognition of on-site images is labor-intensive, and it is difficult to detect and identify small displacements manually; (3) the system is also difficult to automatically alarm, because it is difficult to detect when the line exceeds the limit, etc.

Therefore, it is difficult for the video surveillance system to achieve the purpose of monitoring seamless railway lines in practice.
