An interception device for judging whether to punch a card based on vehicle speed recognition

Abstract

The invention discloses an intercepting device for judging whether to punch a card based on vehicle speed identification, which includes a road surface, the lower side of the road surface is fixedly connected with the lower side road surface, and the side surface of the road surface is fixedly connected with a bead, and the bead is deformable material, the underside of the press bar is provided with a press space, and the press bar can be squeezed and deformed by passing vehicles to increase the pressure in the press space. The right side of the press space is fixedly connected to the ground of the reaction path, and the reaction There is a first-level vehicle speed judging oil circuit on the road surface. The speed of the vehicle passing through the bead is different, so that the degree of deformation of the bead is different, and the degree of deformation is different, so the hydraulic oil pressure is also different. Conversion to identify whether the speed of the vehicle passing through the bead conforms to the characteristics of the punching vehicle, so that the on-duty personnel is not required to participate in the judgment, which improves the reliability of the device. This device designs a two-stage interception device to make the interception more efficient and successful. rate is higher.

Description

technical field [0001] The invention relates to the related field of data identification, in particular to an intercepting device for judging whether to punch a card based on vehicle speed identification. Background technique [0002] Security considerations at the gates of important places often set up checkpoints at the gates. The anti-punching measures at most bayonets are sandbags, which often have no effective effect on purposeful and targeted punching vehicles. The card punching measures mostly depend on the judgment of the on-duty personnel, and whether the card punching measures can play a role largely depends on the on-duty personnel, which greatly reduces the reliability. Contents of the invention [0003] The object of the present invention is to provide an intercepting device for judging whether to punch a card based on vehicle speed identification, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve th...
