Detailed Description
As shown in the figure, the automobile speed detecting station based on the vision system comprises a base station 101, and a controller 107 is installed on the base station 101, or the controller 107 can be installed at other positions according to the space of a detecting workshop. The controller 107 is respectively and electrically connected with an actual speed measuring component, a meter display speed measuring component, a front wheel limiting component, a roller limiting component, a lifting machine and a display.
Specifically, the actual speed measuring component includes a front speed measuring roller 114 and a rear speed measuring roller 102 which are installed on the base platform 101, and anti-slip lines are arranged on the roller surfaces of the front speed measuring roller 114 and the rear speed measuring roller 102, so that the rear wheel 104 of the vehicle can drive the front speed measuring roller 114 and the rear speed measuring roller 102 to rotate together. The front speed measuring roller 114 and the rear speed measuring roller 102 are electrically connected with a speed measuring encoder and a shaping filter. The linear velocity of the front tacho drum 114 and the rear tacho drum 102 is measured by the tacho encoder, so that the actual linear velocity of the rear wheel 104 can be measured. The shaping filter can effectively filter the frequency point of the specific frequency in the power line or the frequency outside the frequency point to obtain a power signal of the specific frequency, the signal transmitted to the controller 107 by the speed measuring encoder is processed by the filter, noise can be filtered or interference of other signals can be avoided, and the controller 107 can conveniently process speed related signals. The controller 107 generates an actual speed change curve from the measured actual speed of the rear wheel 104, and the actual speed change curve is displayed on the display screen. The lifter 103 is installed between the front tachometer drum 114 and the rear tachometer drum 102. When the vehicle is to be detected, the vehicle is driven onto the base 101, the rear wheel 104 is driven onto the lifter 103 between the front speed-measuring drum 114 and the rear speed-measuring drum 102, and the controller 107 controls the lifter 103 to fall, so that the rear wheel 104 is brought into contact with the front speed-measuring drum 114 and the rear speed-measuring drum 102. The meter display speed measurement component comprises a visual recognition system and a voice indication module. During detection, the meter display testing assembly is placed in the carriage, and the vision recognition system is aligned with the speedometer. The driver steps on the accelerator to increase the speed to 40 km/h, the visual recognition system measures the value of the automobile speedometer, the resin is transmitted to the controller 107, and the controller 107 generates the speed variation curve of the speedometer and displays the speed variation curve on the display. According to the curve comparison of the display vehicle speed and the actual vehicle speed, the performance of the speedometer can be detected, and the actual vehicle speed is ensured to be less than or equal to the display vehicle speed. The voice indication module can indicate when the driver steps on the accelerator, keeps the vehicle speed at 40 kilometers per hour for three to five seconds and the like.
In order to prevent the vehicle from rushing out of the detection table during vehicle detection, a front wheel limiting assembly is further mounted on the base 101. Specifically, the front wheel limiting assembly comprises a linear sliding table 106 mounted in a mounting groove formed in the upper end surface of the base table 101, a sliding block 110 is mounted on the linear sliding table 106, and the upper end surface of the sliding block 110 is flush with the upper end surface of the base table 101. A first air cylinder 109 is fixedly mounted on the sliding block 110 through bolt connection, and the first air cylinder 109 is connected with a clamping block 108 through a piston rod. The motor connected with the linear sliding table 106 can be controlled by the controller 107, and the sliding block 110 moves to a designated position, so that vehicles with different wheelbases can be limited. After the sliding block 110 moves to a designated position, the first cylinder 109 can drive the piston rod to drive the fixture block 108 to move to one side of the front wheel 105, and the fixture block 105 abuts against the front wheel 105, so that the vehicle cannot move forwards. In order to facilitate the withdrawal of the latch 108, a pulley is installed at a lower end of the latch 108. The sliding direction of the pulley is the same as the moving direction of the driving clamping block 108 of the cylinder I109.
After the vehicle detection is finished, the controller 107 controls the lifter to lift the rear wheels 104 away from the front speed measuring roller 114 and the rear speed measuring roller 102, and in order to avoid the influence of the front speed measuring roller 114 capable of rolling on the vehicle exiting, a roller limiting component is installed on one side of the front speed measuring roller 114. Specifically, the roller limiting assembly comprises a second cylinder 111 mounted in the base 101 on the end face side of the front speed measuring roller 114, the second cylinder 111 is connected with a first stop block 112 through a piston rod, and a second stop block 113 is fixedly mounted at one end of the roller body of the front speed measuring roller 114 through welding. When the front speed measuring roller 114 needs to be prevented from rotating, the controller 107 controls the second cylinder 111 to drive the piston rod to drive the first stopper 112 to move to one end of the front speed measuring roller 114, and the first stopper 112 can block the second stopper 113, so that the front speed measuring roller 114 cannot rotate, and the vehicle can conveniently run out.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
