A multi-sensor based vehicle access management control system and control method thereof

Abstract

The invention discloses a multi-sensing-based vehicle access management control system and a control method thereof, comprising: a geomagnetic induction module, an infrared sensing module, a signal processing module, a digital-to-analog conversion module, a wireless transmission module, and a driving module. The magnetic induction module judges whether there is a vehicle entering by sensing the transceiving magnetic field transformation; the infrared sensing module performs vehicle position prediction under the operation of the geomagnetic induction module to improve the passing rate of the vehicle; the signal processing module detects the signal of the induction sensor. The neutral modulation completes the stable transmission of the detection signal; the digital-to-analog conversion converts the continuous analog signal obtained by detection into a discrete digital signal to complete the signal conversion; the wireless transmission module performs signal adjustment under the digital-to-analog conversion The transmission and reception of wireless signals; the drive module drives the transmission of the power supply under the signal reception of the wireless transmission module. By strengthening the response and sleep of the acquisition system, the passing rate of the vehicle is improved and the loss of electric energy is reduced.

Description

technical field [0001] The invention relates to a vehicle access control technology, in particular to a multi-sensing-based vehicle access management control system and a control method thereof. Background technique [0002] With the rapid development of our country's economy and the continuous improvement of people's living standards, automobiles have become an increasingly important means of transportation. They are not only widely used in various enterprises and institutions, but also increase in household cars. Therefore, modern parking garages The need for management equipment has also put forward higher operational requirements. [0003] At present, the vehicle entry and exit management system of the parking lot mostly adopts the traditional manual lifting and lowering methods and the semi-intelligent control method to detect and register the incoming and outgoing vehicles. However, during the peak period of vehicle entry and exit, there will be congestion and cause ve...

[0003] At present, the vehicle entry and exit management system of the parking lot mostly adopts the traditional manual lifting and lowering methods and the semi-intelligent control method to detect and register the incoming and outgoing vehicles. However, during the peak period of vehicle entry and exit, there will be congestion and cause vehicles to stay. , delay travel time, and in the face of a large number of vehicles stranded, it is impossible to ensure the information of vehicles and personnel in the parking area when using fast access; while the traditional vehicle access control system uses images to collect license plate information, and then registers the collected information with the computer In order to allow the entry and exit of the vehicle, the vehicle's stop position must be within the detection range of the image acquisition system to accurately obtain the vehicle information when collecting the image of the license plate information of the entering and exiting vehicle, which will cause the driver to be unable to intuitively judge. Whether the parking position of the vehicle is within the image acquisition range, and then the distance between the vehicle and the image acquisition system needs to be adjusted to obtain vehicle information accurately, and this method will affect the driving of the rear vehicles and cause congestion
