Speed measurement snapshot device

Abstract

The invention provides a speed measurement snapshot device, which is used for acquiring an image of a moving object in a target area, and comprises a host shell, a support, a speed measurement module, at least one image acquisition module and control units, wherein the host shell is arranged at the top of the support, and the support is in a vertically-arranged rod shape; the speed measurement module is arranged on the host shell and is used for monitoring a moving signal of a moving object; the at least one image acquisition module is arranged in the host shell and is used for shooting a video signal of the moving object and acquiring image information of the moving object, and the image acquisition module is arranged in the host shell through an angle adjusting mechanism; the control units are arranged in the host shell, and the control units are in one-to-one correspondence with the image acquisition modules; and the output end of the speed measurement module is connected with a trigger port of the image acquisition module, and the image acquisition module is started according to the moving signal and / or the video signal output by the speed measurement module to acquire image information and transmits the image information to the corresponding control unit.

Description

technical field [0001] The invention relates to the field of image acquisition equipment, in particular to a speed measuring and capturing device. Background technique [0002] In the traditional technology, the speed measurement and capture system is mostly an independent capture unit, speed measurement unit, supplementary light unit and storage unit process, and the system is complicated to set up; most of the existing test and capture all-in-one machines can only realize the integration of speed measurement and capture modules, and the integration degree is low. Most of them need to be erected on the gantry, which is difficult to install and debug on site, and the maintenance cost is high. It is impossible to erect and use for no gantry places. [0003] For existing speed measuring equipment, the cabinet is usually made of metal materials such as steel plates and aluminum plates. If the antenna module is placed inside the cabinet, the signal will be shielded. Most commun...

Problems solved by technology

[0002] In the traditional technology, the speed measurement and capture system is mostly an independent capture unit, speed measurement unit, supplementary light unit and storage unit process, and the system is complicated to set up; most of the existing test and capture all-in-one machines can only realize the integration of speed measurement and capture modules, and the integration degree is low. Most of them need to be erected on the gantry, which is difficult to install and debug on site, and the maintenance cost is high

For places without gantry frames, it is impossible to erect and use

[0003] For existing speed measuring equipment, the cabinet is usually made of metal materials such as steel plates and aluminum plates. If the antenna module is placed inside the cabinet, the signal will be shielded. Most communication antennas are placed directly on the top or side of the case, but the appearance is ugly and the antenna is easy to lose. , or cause damage; patent CN109257892A, a traffic signal equipped with an antenna module mentioned a solution, a square window is opened on the top of the cabinet, but the surrounding antenna signal performance is greatly affected

And usually the size of the antenna is large, the radome needs to be completely covered, and the size needs to be large. If it is completely processed by injection molding process, due to the large size, the mold cost is very high
