Problems solved by technology

It can be seen that the existing interval speed measuring devices have a large number of components, so the product integration is low, the product volume is large, the cost is high, and the installation and maintenance are also relatively cumbersome
Since the back-end server is a CPU running software algorithm mode, it requires high CPU performance, high server cost, and low image resolution and frame rate

Abstract

The embodiment of the invention provides speed measuring equipment and a speed measuring system, and relates to the technical field of electronic control. Front-end acquisition equipment acquires first image information of a first monitored area, and recognizes first license plate information in the first image information; the speed measuring equipment receives the first license plate informationand the first image information, acquires the receiving time of the first license plate information, acquires second image information of a second monitored area, recognizes second license plate information in the second image information, and acquires the acquisition time of the second license plate information; if the second license plate information is the same as the first license plate information, according to the time difference between the receiving time and the acquisition time and the distance between the front-end acquisition equipment and the speed measuring equipment, the vehiclespeed of a vehicle corresponding to the second license plate information is calculated; if the vehicle speed exceeds a set vehicle speed, the image information and the license plate information of the overspeed vehicle and the vehicle speed are sent to a monitoring terminal. Through the speed measuring equipment and the speed measuring system, license plate information recognition, vehicle speedcalculation and vehicle overspeed judgment are achieved, and a product is high in integration degree, small in volume and low in cost.

Description

technical field [0001] The invention relates to the technical field of electronic control, in particular to a speed measuring device and a speed measuring system. Background technique [0002] The existing interval speed measurement device is equipped with one or a group of cameras at the start point and the end point of the speed measurement. Through the camera, the road image is captured and compressed in real time, and then transmitted to the back-end server. The back-end server runs a specific algorithm. The license plate information of the speed measurement start point and the speed measurement end point is identified, and then the average speed of the vehicle is calculated according to the detected time of the speed measurement start point and the speed measurement end point and the total length of the speed measurement interval. If overspeeding, the identified license plate information and overspeeding situation will be sent to the management terminal for display. ...
