The detection principle is shown in fig. 2, and the details are as follows:

in order to obtain complete contour data of the train tire, the point laser displacement sensor and the binocular stereo camera are respectively installed and fixed on a sliding table installed in the linear module, the central axes of two lenses of the binocular stereo camera are perpendicular to the tire, and the point laser displacement sensor and the tire form a certain angle and keep a constant distance L. When the train tire 7 passes through the speed measuring assembly, the train tire continues to roll forwards, when the distance between the point laser displacement sensor and a certain point of the train tire just reaches a preset distance L, the central processing unit controls the binocular stereo camera to start working, the distance L not only meets the requirement that the binocular stereo camera can shoot complete tire contour information through a reserved detection hole on the straddle type monorail track beam, but also considers the measuring range of the point laser displacement sensor.

In order to keep the distance L unchanged, the central processing unit controls the rotating speed of the servo motor through the controller, and further, the transmission speed (shown as the moving speed V2 of the sliding table in figure 1) of the linear module is consistent with the running speed (shown as V1 in figure 1) of the train in the whole image acquisition process; in addition, the binocular stereo camera is controlled by a program to start to acquire the complete contour data of the train tire entering the detection section. When the sliding table passes through the photoelectric switch at the tail end of the linear module, the binocular stereo camera stops data acquisition, the sliding distance of the sliding table in the image acquisition process is just equal to the circumference of a train tire rolling circle, the central processing unit controls the servo motor to rotate forward and backward through a program, and the linear module returns to the initial detection original position, so that the measurement system acquires the complete contour data of the straddle type monorail train tire.

The central processing unit is responsible for power supply of the system and acquisition, processing, storage and display of data. The central processing unit respectively supplies power to the trigger assembly, the speed measuring assembly (namely the real-time speed measuring assembly), the synchronous following assembly (comprising a servo motor and the like) and the image acquisition assembly, on one hand, the trigger signal of the trigger assembly is received, on the other hand, the interval pulse signal of the speed measuring assembly and the distance information of the point laser displacement sensor are also received, the data are processed and analyzed through the processor, the servo motor is controlled through the controller, the binocular stereo camera and the point laser displacement sensor realize the synchronous acquisition of the complete data of the profile of the straddle type monorail train tire, finally, the profile data acquired by the binocular stereo camera are obtained, the abrasion information of the train tire is obtained through the data processing of the central processing unit, and the abrasion information is stored and displayed.

The speed measurement assembly realizes closed-loop control on pre-adjustment of the speed of the electric sliding table through the PID control module, so that image data acquired by a subsequent synchronous following system is more accurate and more effective. The binocular stereo camera is in information communication with the central processing unit through the network interface, the processor integrates the groove measurement result with a third-party system through the network interface or the serial port, and the result data can be displayed on the interface through the HDMI. The PID control module and HDMI can refer to the prior art.

In the present embodiment, the detailed description of the related schemes can be referred to in the prior art.

By applying the scheme of the embodiment, the effects are as follows: set up the laser displacement sensor of point on the straight line module slider through under the track roof beam preformed hole of putting into storage the traveles at the monorail train of striding, and detect and walk the distance information between the wheel by this laser displacement sensor of point, guarantee through controller control servo motor that straight line module slip table speed keeps unanimous with the train speed of traveling, thereby realize installing the two mesh stereo camera on straight line module slip table and to the synchronous complete collection of train tire profile data, through data analysis and processing, the wearing and tearing information of measurable out tire, compare in the non-contact measurement of prior art, have the advantage in two big aspects: (1) the complex and tedious detection process is not needed, the system is simple in structure, high in timeliness, high in stability and high in detection precision; (2) the positions of the photoelectric switches and the binocular camera which are installed on the linear module can be changed to measure the tires of the straddle monorail train with different vehicle types and different vehicle speeds, and the system is more comprehensive in function.

By adopting the scheme of the invention, the rotating speed of the servo motor is controlled through the distance information between the point laser displacement sensor and a certain position on the straddle type monorail train tire, and the binocular stereo camera is arranged on the linear module.

The scheme of the invention can improve the detection precision, effectiveness and real-time performance of the abrasion state of the rubber tire running on the straddle type monorail train, and can alarm and inform maintenance units and maintenance personnel in time through real-time detection and monitoring, thereby effectively reducing the potential safety hazard of train operation.
