specifically, one wheel set comprises one wheel shaft, and two ends of the wheel shaft are respectively provided with a wheel disc.
S20, when the wheel disc and the wheel shaft of the rail transit vehicle are detected by the second wheel pair infrared distance measurement sensor, the wheel shaft infrared distance measurement sensor detects the central line and/or the edge line of the wheel shaft, the first image information acquisition module of the image information acquisition module 13 acquires the central line and/or the edge line of the wheel shaft, and when the distance between the image central line of the first image information acquisition module and the central line of the wheel shaft is within a first set error range, the inspection walking robot 10 reaches an inspection station at the moment and controls the inspection walking robot 10 to stop moving;
s30, judging whether the deviation between the image collected by the first image information collection module of the image information collection module 13 and the template image is within a second set error range, wherein the second set error range is within the first set error range;
if yes, directly controlling the inspection mechanical arm 12 to reach an inspection point according to the planned motion track; if not, adding a first correction quantity to the lifting module, or adding a second correction quantity to the planned motion track of the inspection mechanical arm 12, and controlling the inspection mechanical arm 12 to reach an inspection point, so that the deviation between the inspection point image acquired by the second image information acquisition module and the target image is within a third set error range.
That is, in step S30, when the deviation between the inspection point image acquired by the second image information acquisition module and the target image is within the third set error range, the inspection mechanical arm 12 reaches the inspection point, and the acquired information is valid information.
Since the inspection walking robot 10 itself has inertia when controlling the inspection walking robot 10 to stop moving in step S20, there is a possibility that there is a deviation from the inspection station, which may cause an error between the inspection robot arm 12 and the inspection point, and therefore, it is necessary to determine whether the inspection robot arm 12 reaches the inspection point.
Meanwhile, even if the inspection walking robot 10 is accurately stopped at the inspection station, there is a possibility that an error exists between the inspection robot 12 and the inspection point due to a posture problem of the inspection robot 12 itself. Therefore, the error needs to be further eliminated by step S30.
When the deviation between the image acquired by the second image information acquisition module of the image information acquisition module 13 and the template image is not within the second set error range, it indicates that an error exists between the inspection robot 12 and the inspection point. If the error is caused by the fact that the patrol walking robot 10 itself has inertia when the patrol walking robot 10 is controlled to stop moving, and thus a deviation is generated between the patrol walking robot 10 and the patrol station, the movement of the lifting module or the movement of the patrol robot arm 12 is controlled, so that the deviation of the patrol walking robot 10 can be compensated to the movement of the lifting module or the patrol robot arm 12, and finally the patrol robot arm 12 reaches a patrol point. And because the patrol inspection walking robot 10 has a large weight, the deviation of the patrol inspection walking robot 10 is compensated to the movement of the lifting module or the patrol inspection mechanical arm 12, and the adjustment is more accurate. If the error is caused by the posture problem of the inspection mechanical arm 12, the error can be eliminated by controlling the movement of the lifting module or the movement of the inspection mechanical arm 12, and the accuracy of the information acquisition of the second image information acquisition module is ensured.
Specifically, the inspection data analysis and management platform 20 stores template images of each inspection station and target images of each inspection point.
In the method for detecting the bottom of the rail transit vehicle provided by the embodiment, the inspection walking robot 10 travels along an inspection path, the initial position of the task is positioned in a vertical distance measurement mode by using an infrared laser distance measurement sensor, and the specific position of the carriage and the key position of the inspection task are positioned through the wheel axle visual characteristic and the mileage calculation information at the bottom. Therefore, the device is well suitable for the working characteristics of rail transit vehicle maintenance, effectively reduces the cost and is convenient to implement.
Further, in order to avoid the situation that the obstacle enters the working distance range in the operation, laser radars are installed on the front portion and the tail portion of the chassis of the inspection walking robot 10, a safety region is defined according to the braking distance, and sound and light alarm information is sent out and the robot is decelerated and stopped according to the obstacle distance information entering the working distance range. Meanwhile, the force sensor based on the inspection mechanical arm 12 detects the obstacles in the working space range in real time, so that the safety of the detected equipment is ensured.
The patrol inspection walking robot 10 accurately stops when walking to a bogie wheel shaft, the patrol inspection mechanical arm 12 performs track recurrence, and sequentially collects images of each key position of the bogie according to a preset pose, so that the image information collection module 13 can accurately collect image information, and an accurate information source is provided for image analysis defect detection work.
