Vehicle access management control system based on multiple sensors and control method thereof

Abstract

The invention discloses a vehicle access management control system based on multiple sensors and a control method thereof. The vehicle access management control system comprises a geomagnetic induction module, an infrared sensing module, a signal processing module, a digital-to-analog converter, a wireless transmission module and a driving module, and the geomagnetic induction module judges whether a vehicle enters or not by sensing the conversion of a transceiving magnetic field. The infrared sensing module prejudges the position of the vehicle under the operation of the geomagnetic inductionmodule, so that the passing rate of the vehicle is improved. The signal processing module performs neutralization modulation on signals detected by the inductive sensor to complete stable transmission of detection signals. The digital-to-analog conversion is used for converting detected continuous analog signals into discrete digital signals to finish signal conversion. The wireless transmissionmodule is used for transmitting and receiving wireless signals under the signal adjustment of digital-to-analog conversion. The driving module drives the transmission of the power supply under the signal receiving of the wireless transmission module, improves the passing rate of vehicles by enhancing the response and dormancy of the acquisition system, and reduces the loss of electric energy.

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.

[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
