Description

A method and system for automatic identification of far and near ends of a wheel simulator

technical field

The invention belongs to the technical field of debugging and maintenance of train security inspection equipment, and in particular relates to an automatic identification method and system for far and near ends of a wheel simulator.

Background technique

At present, the railway trackside fault image detection equipment (TFDS, TVDS, TEDS) mainly includes trackside equipment and detection station equipment. The trackside equipment includes: two remote wheel sensors, two proximal wheel sensors, image acquisition equipment, etc. The installation positions of the trackside equipment are the far-end wheel sensor, the near-end wheel sensor and the image acquisition equipment in sequence. 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 equipment is ready to pick up the train when the wheels of the train pass the remote wheel sensors No. 1 and No. 2 in turn, and the image acquisition starts when the wheels pass through the near-end wheel sensors No. 3 and No. 4.

After the equipment is installed and debugged and the operators go online for maintenance and troubleshooting, since there is no train passing by the wheel sensor within the on-site operation skylight time, the software of the equipment can only be used to simulate the passing of the train to trigger the image acquisition equipment to collect images. Whether the wheel sensor can work normally can not be detected by software simulation. Therefore, the assistance of the wheel simulator is also needed. The wheel simulator device is placed above the wheel sensor to simulate the train wheel passing the wheel sensor, thereby triggering the image acquisition device to collect images.

The wheel simulator is divided into a remote wheel simulator and a near-end wheel simulator. The remote wheel simulator is placed on the far-end No. 1 and No. 2 wheel sensors, and the near-end wheel simulator is placed on the near-end No. 3 and No. 4 above the number wheel sensor. Use the remote control to control the two wheel simulators to work. It can be equipped with a rotating roller fixed in front of the image acquisition device, and the image acquisition device can collect the image of the roller to check the quality of the image.

But the problem is that it needs to determine which is the far-end wheel simulator and which is the near-end wheel simulator. 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 methods can be used:

1) To distinguish the two wheel simulators in terms of appearance or structure, two types of appearance and abrasive tools need to be designed to make a difference in appearance or structure. The cost is too high, and there will be a chance of misplacement during on-site use.

2) On-site manual setting of the two wheel simulators. Due to the tight schedule of the on-site work and the long distance between the far end and the near end, the manual setting is not very user-friendly, which will not only increase the extra workload, but also cause the probability of setting errors . At the same time, prevent the wheel simulator, roller or remote control from being left on the scene, affecting the train travel and even causing the train to go off-line.

Contents of the invention

Example 1:

In this embodiment, the installation diagram of the image acquisition device is shown in Figure 1. The No. 1 and No. 2 wheel sensors are installed at the far end, and the No. 3 and No. 4 wheel sensors are installed at the near end. No. wheel sensor, No. 3 and No. 4 wheel sensors, stimulate the sensor to work.

When there is no need to check the shooting angle of the image acquisition device on site, the scroll wheel does not work, and the remote control selects the non-roller mode. If the scroll wheel needs to work when the scene needs to check the shooting angle of the image acquisition device, the remote control selects the scroll wheel mode.

1) When the remote controller works in the non-roller mode, the schematic diagram of the non-roller mode is shown in Figure 2. The operator needs to keep the remote controller within a radius of 30 meters from the image acquisition device. The longitude, latitude and other information of the positioning devices of the end wheel simulator and the remote wheel simulator, and then calculate the distance from the near-end wheel simulator to the remote control and the distance from the far-end wheel simulator to the remote control, according to the near-end wheel simulation The distance from the controller to the remote controller is smaller than the distance from the far-end wheel simulator to the remote controller to determine the far-end and near-end. The wheel simulator can only be operated after the far and near ends are identified.

If the remote control is in the middle position between the near-end wheel sensor and the far-end wheel sensor (actually, it is the middle position between the near-end wheel simulator and the far-end wheel simulator), it will not be able to distinguish the far end from the near end. If the remote control is close to the far end, it will The far-end will be recognized as the near-end, so the operator should be kept within a radius of 30 meters centered on the image acquisition device, so that the distance from the near-end wheel simulator to the remote control will definitely be smaller than the distance from the far-end wheel simulator to the remote control device distance.

When the wheel simulator is not operating, when it is detected that the distance between the near-end wheel simulator or the far-end wheel simulator and the remote control is greater than 120 meters, the remote control and the two wheel simulators will send out anti-lost alarms, and the three devices The missing alarm is issued so that no matter which device is lost, people in the vicinity of the three devices can know that there is a missing device.

The distance from the remote wheel simulator to the image acquisition device is 80 meters, plus the radius from the image acquisition device to the remote control is 30 meters, a total of 110 meters is the working range of the device, and 120 meters means that people are considered to have gone beyond the working range by 10 meters. But the wheel simulator was left on the scene.

2) When the remote controller is working in the wheel mode, the schematic diagram of the wheel mode is shown in Figure 3. First, obtain the information such as longitude and latitude of the positioning devices of the wheel, the proximal wheel simulator and the remote wheel simulator, and then calculate The distance from the near-end wheel simulator to the roller and the distance from the far-end wheel simulator to the roller can be automatically judged according to the distance from the proximal wheel simulator to the roller is smaller than the distance from the far-end wheel simulator to the roller. and remote. The wheel simulator can only be operated after the far and near ends are identified.

The positions of the roller, the near-end wheel simulator and the far-end wheel simulator are fixed, so after the positioning device is installed on the roller, it can be judged who is the near-end and who is the far-end through the three fixed positions, so that the remote control The position will be more flexible, and the remote control can be moved between the near end and the far end near the far end.

When the wheel simulator is not operating, when it is detected that the distance between the near-end wheel simulator or the far-end wheel simulator and the roller is greater than 120 meters or the distance between the roller and the remote controller is greater than 120 meters, the remote controller, the roller and the two wheels simulate The device will send out anti-lost alarm.

The above calculation example of the present invention is only to describe the calculation model and calculation process of the present invention in detail, but not to limit the implementation of the present invention. For those of ordinary skill in the art, on the basis of the above description, other changes or changes in different forms can also be made, and all implementation modes cannot be exhaustively listed here. Obvious changes or modifications are still within the protection scope of the present invention.
