System and method for detecting entrance guard barrier gate based on laser radar

Abstract

The invention discloses a system for detecting an entrance guard barrier gate based on a laser radar. The system comprises a TOF laser barrier gate triggering radar, a TOF laser barrier gate anti-smashing radar, an image acquisition module, a control module, a gate machine driving module, a voice and display module, a server and a power module. The system has the beneficial effects that the triggering rate of the TOF laser barrier gate triggering radar is high, the vehicle recognition rate is high, and zero error can be achieved; the system is small in size, infrared rays are transmitted actively, the interference resistance is high, the acquisition precision is also high, the cost is low, the construction is simple, the pavement is not damaged, and the construction difficulty and the maintenance cost are greatly reduced; and the TOF laser barrier gate anti-smashing radar can effectively avoid events of smashing vehicles and hitting persons.

Description

technical field [0001] The invention relates to an access control automation control technology, in particular to a laser radar-based access control barrier detection system and method. Background technique [0002] Access control gates are mainly used in residential areas, units, schools, shopping malls, companies and parks where there are parking lots. It is generally combined with a property management system or a parking lot management system to identify vehicles and people, thereby helping property management or Parking lot management system improves efficiency. [0003] The existing access control barrier detection system mainly detects the existence of vehicles and the identification of vehicle models through geomagnetic sensors, which are usually buried under the ground at the entrance and exit of the gate, and are divided into trigger geomagnetic sensing coils and anti-smashing geomagnetic sensing coils . [0004] However, detection by geomagnetic sensors has the ...

Problems solved by technology

[0007] For the access control barrier system of millimeter-wave radar, although it can also partially solve the problems existing in detection by geomagnetic sensors, there are the following problems at the same time: (1) The miniaturization of millimeter-wave radar is very difficult, and the power consumption is relatively high; (2) ) millimeter-wave radar is expensive; (3) millimeter-wave radar beams are easy to diverge, it is difficult to converge to a smaller radiation area, and the detection accuracy is not high; (4) some cars will produce strong electromagnetic radiation, millimeter-wave radar anti-electromagnetic interference effect Poor; (5) millimeter wave radar cannot image
