System and method for detecting turnout and switch point closure of turnout

Abstract

The invention discloses a system and method for detecting a turnout and switch point closure of the turnout. The method includes the steps that distance information between a first point rail and a first basic rail is acquired through a first range finder; then, the distance information on the first range finder is read by an information processing device and converted into a switch point closurevalue of the turnout, and the switch point closure value of the turnout is transmitted to a monitoring center, so that an operator accurately obtains the switch point closure state between the first point rail and the first basic rail and can accurately and safely carry out shunting guidance operation, and the running safety of a locomotive on the turnout is greatly improved. Since the first rangefinder is directly arranged on the first point rail or the first basic rail, the first range finder can directly obtain the distance between the first point rail and the first basic rail without inverse calculation operation, so that the operation error caused by input of the obtained switch point closure value is avoided, and the accuracy of the switch point closure value of the turnout is greatly improved.

Description

technical field [0001] The invention relates to the technical field of railway detection, in particular to a switch and a switch close-fit detection system and method. Background technique [0002] Turnout close contact means that the gap between the tip rail and the basic rail is within a certain range and does not affect the driving safety. This state is defined as the switch close contact state. In railway stations without electrification transformation, the turnouts are non-interlocking turnouts. In the actual operation process, the operators need to manually confirm the closeness of the turnouts, and use the feeler gauge to detect the closeness value of the turnouts. This method not only increases the labor intensity , and the test results are completely dependent on personal experience and eyesight, and the rate of misjudgment or missed judgment is high, resulting in the failure to effectively guarantee the safety of locomotive driving. [0003] To this end, someone s...

Problems solved by technology

However, this method is easy to introduce back-calculation errors, resulting in deviations in the obtained close-fitting values, and cannot accurately and safely implement shunting guidance operations, which poses a major safety hazard to the locomotive driving process

At the same time, in the outdoor environment, the detector is easily affected by the outside world, such as dust, leaves, plastic bags and other sundries, which seriously affect the detection results of the switch closeness value
