Abstract

The embodiment of the invention discloses a motor vehicle running speed acceleration measuring system based on photoelectric detection. A receiving device receives laser emitted by an emitting deviceto form a light path. Then, through on-off signals of the light paths, passing vehicles are captured, on-off of the light signals of the light paths is converted into electric signals, and then an electric control system of the receiving device can record the connection time and disconnection time of all the light paths; and the speed and acceleration of the vehicle are calculated according to thedistance between a left speed laser and a right speed laser, the length of the vehicle, the connection time and the disconnection time. According to the embodiment of the invention, a fixed point ona wheel does not need to be detected, the on-off of the optical path is detected, and the on-off signal of the optical path and the connection time and the disconnection time of each optical path areactually measured and are objective and accurate, so that the accuracy of measured data can be ensured, and the accuracy of speed measurement is improved; and meanwhile, the acceleration can be measured.

Description

technical field [0001] The invention relates to the technical field of speed measurement, in particular to a photoelectric detection-based motor vehicle speed acceleration measurement system. Background technique [0002] At present, for road traffic safety, it is necessary to measure the speed and acceleration of motor vehicles, that is, to measure the speed and acceleration of driving motor vehicles at designated road monitoring points. [0003] The existing measurement method uses laser technology for speed measurement, which is to emit laser signals to designated points on the wheels at different times, and calculate the displacement and movement time of the vehicle according to the laser signals fed back by the wheels, and then calculate the displacement and movement time according to the displacement of the vehicle. and motion time to calculate the wheel speed. However, in this method, the consistency of the fixed points on the wheels cannot be guaranteed, and it is d...
