Access control system and access control method

Abstract

The invention relates to the field of hazardous chemical substance vehicles, and discloses an entrance guard control system and method. The entrance guard control system comprises: an electronic lockmodule installed on the oil tanker and used for controlling an oil valve of the oil tanker to be opened or closed; an entrance guard control module that comprises a vehicle number identification unitused for identifying the license plate number of the oil vehicle; a car stopper; and an entrance guard control unit that is used for sending the recognized license plate number and controlling the carstopper to act so as to allow or forbid an oil car to pass, and the electronic lead sealing module is used for receiving the recognized license plate number and detecting the state of an electronic lock module of the oil car corresponding to the license plate number, wherein the entrance guard control unit is used for controlling the motion of the car stopper, and comprises the following steps: receiving the state of the electronic lock module, and controlling the motion of the car stopper under the condition that the electronic lock module is in a sealing state so as to allow an oil car to pass. According to the invention, full-automatic inspection of the state of the electronic lock module can be realized during warehouse-in and warehouse-out of the oil tanker, so that the manual intervention link is reduced, and the execution efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of hazardous chemical vehicles, in particular to an access control system and an access control method. Background technique [0002] As the market demand for refined oil continues to expand, the requirements for the safety and reliability of refined oil depots are also getting higher and higher. In order to adapt to the standardization and modernization of oil storage and transportation management, the access control system, as part of the automation of oil depot management, can greatly reduce the workload of oil depot management, prevent tank cars from queuing up in the depot, and improve the safety of the oil depot. More importantly, the access control system has a network communication function, which is convenient for the intelligent information management of the oil depot. [0003] In order to realize the visual management of internal distribution vehicles, some existing oil depots have installed intelligent el...
