Description
Technical Field
The invention belongs to the technical field of debugging and overhauling of train safety inspection equipment, and particularly relates to a method and a system for automatically identifying the far end and the near end of a wheel simulator.
Background
At present, railway rail edge fault image detection equipment (TFDS, TVDS, TEDS) mainly comprises rail edge equipment and detection station equipment, wherein the rail edge equipment comprises: two distal wheel sensors, two proximal wheel sensors, an image capture device, and the like. The mounting positions of the rail side equipment are a far-end wheel sensor, a near-end wheel sensor and image acquisition equipment in sequence, wherein the distance from the far end to the image acquisition equipment is about 80 meters, and the distance from the near end to the image acquisition equipment is about 5 meters.
The normal working process of the equipment is as follows: the train wheel is ready to receive when passing through the far-end wheel sensor No. 1 and the far-end wheel sensor No. 2 in sequence, and image acquisition is started when the wheel passes through the near-end wheel sensor No. 3 and the near-end wheel sensor No. 4.
After the equipment is installed and debugged and operators are overhauled and troubled on line, no train passes through the wheel sensor within the time of skylight in field operation, and the software of the equipment can be only used for simulating the train to pass through to trigger the image acquisition equipment to acquire images. Software simulation cannot detect whether the wheel sensor can work normally. Therefore, the auxiliary of a wheel simulator is needed, and the wheel simulator device is placed above the wheel sensor and used for simulating the train wheel to pass through the wheel sensor, so that the image acquisition device is triggered to acquire an image.
The wheel simulator is divided into a far-end wheel simulator and a near-end wheel simulator, wherein the far-end wheel simulator is placed on the No. 1 and No. 2 wheel sensors at the far end, and the near-end wheel simulator is placed on the No. 3 and No. 4 wheel sensors at the near end. And the remote controller is adopted to control the two wheel simulators to work. The rolling wheel fixed in front of the image acquisition equipment can be matched, and the image acquisition equipment can acquire the image of the rolling wheel to check the quality of the image.
However, the problem is to determine which is the far-end wheel simulator and which is the near-end wheel simulator, and in order to distinguish which of the two wheel simulators is placed at the near-end and which is placed at the far-end, the following method can be adopted:
1) The two wheel simulators are distinguished in appearance or structure, two appearances and grinding tools need to be designed for distinguishing in appearance or structure, the cost is too high, and the probability of placing errors can occur during field use.
2) The two wheel simulators are manually arranged on site, and because the time of the field working skylight is short and the distance between the far end and the near end is long, the manual arrangement is not humanized, so that extra workload can be increased, and the probability of arrangement errors can be increased. Meanwhile, the wheel simulator, the roller or the remote controller is prevented from being left on the site, so that the train is influenced by the same trip and even the train is prevented from being off-line.
Disclosure of Invention
The invention aims to solve the problems that in the process of simulating the train passing by using software to trigger the image acquisition equipment to acquire images, the working state of a wheel sensor cannot be detected when the train passes by, so that the assistance of a wheel simulator is required, the workload is large when the wheel simulator is manually distinguished at present, and the cost is high when the wheel simulator is distinguished.

When the wheel simulator is not operated to work, when the distance from the near-end wheel simulator or the far-end wheel simulator to the roller is detected to be larger than 120 meters or the distance from the roller to the remote controller is detected to be larger than 120 meters, the remote controller, the roller and the two wheel simulators can send out anti-drop alarm.
The above-described calculation examples of the present invention are merely to describe the calculation model and the calculation flow of the present invention in detail, and are not intended to limit the embodiments of the present invention. It will be apparent to those skilled in the art that other variations and modifications of the present invention can be made based on the above description, and it is not intended to be exhaustive or to limit the invention to the precise form disclosed, and all such modifications and variations are possible and contemplated as falling within the scope of the invention.
