[0016] The following further explains the present utility model in conjunction with the drawings and specific embodiments.

[0017] An embodiment of the present utility model discloses a data acquisition device for motorcycle tests (abbreviated as "data acquisition device"), which respectively transmits data with motorcycle test vehicles and test servers, and includes an integrated column and a control cabinet.

[0018] As shown in Figure 1 , the integrated column mainly includes a column body 1, a wireless access point 2, an antenna clamp 3, a camera 4, a camera bracket 5, a positioning antenna 6, an antenna bracket 7, a differential reference station 8, and a reference station clamp 9.

[0019] The column body 1 is a cylindrical structure, and the bottom is buried in the ground in the form of a foundation.

[0020] The wireless access point 2 (AP) is fixed on the top of the column body 1 through the antenna clamp 3 and transmits data with the motorcycle test vehicle through a wireless network. It can be understood that a wireless access point for cooperative use is also provided on the motorcycle test vehicle.

[0021] The antenna bracket 7 is fixedly installed on the upper part of the column body 1, and can be specifically fixed on the column body 1 by means of hoop, screw or welding, etc., and is mainly used for installing and positioning the antenna 6.

[0022] The positioning antenna 6 is fixed on the antenna bracket 7 by screws and performs positioning by receiving satellite signals.

[0023] The camera bracket 5 is fixed at the end of the antenna bracket 7 and is mainly used for installing the spherical camera 4.

[0024] The camera 4 is fixed on the camera bracket 5 and is used to obtain video data during the motorcycle driving test. Preferably, the camera 4 is a spherical camera to achieve 360-degree rotation shooting. The rotation and lens functions of the spherical camera enable it to capture images from more angles.

[0025] The differential reference station 8 is fixed on the column body 1 by the reference station hoop 9, and can be specifically fixed at the middle or upper-middle position. The differential reference station 8 is used in conjunction with the positioning antenna 6 to calculate the correction amount of differential positioning.

[0026] As Figure 2 shown, a switch 10, an optical fiber transceiver 11 and a power supply 12 are fixedly installed in the control cabinet.

[0027] The switch 10 is respectively connected to the wireless access point 2, the camera 4, the differential reference station 8 and the optical fiber transceiver 11 through network cables. It sends the video data collected by the camera 4 to the examination server through the optical fiber transceiver 11; the switch 10 receives the correction amount of differential positioning sent by the differential reference station 8 and sends the correction amount of differential positioning to the motorcycle examination vehicle through the wireless access point 2; the power supply 12 is used to supply power to each component in the device.

[0028] The intelligent motorcycle examination site adopts a leading high-precision differential positioning system and intelligent sensing technology. In actual application, integrated columns and control cabinets are installed in the examination site, and on-vehicle examination terminals and on-vehicle positioning devices are installed on the motorcycle examination vehicles. The video monitoring data collected by the integrated columns and the examination result data analyzed and calculated by the on-vehicle examination terminals can be transmitted to the background examination server through the control cabinets. Specifically, the camera 4 collects the video data of the examination site in real time and sends the collected video data to the switch 10 connected to it through a network cable. The switch 10 then sends the video data to the examination server through the optical fiber transceiver 11. The differential reference station 8 and the positioning antenna 6 are used in cooperation to calculate the correction amount for differential positioning and send the correction amount to the motorcycle examination vehicle through the switch 10 and the wireless access point. The on-vehicle examination terminal on the motorcycle examination vehicle corrects the received positioning data according to the correction amount of differential positioning to obtain the accurate position information of the motorcycle examination vehicle for the on-vehicle examination terminal to analyze and evaluate the examination results. In addition, the wireless access point can also be used to receive the examination result data sent by the on-vehicle examination terminal and send the examination result data to the examination server through the switch 10 and the optical fiber transceiver 11.
