Abstract
The utility model discloses an intelligent vehicle access control system based on an ultrahigh frequency RFID (radio frequency identification) reader-writer. The intelligent vehicle access control system comprises a vehicle recognition card and roadside devices, wherein the roadside devices comprise an antenna, a high-frequency RFID reader-writer, a computer database and a railing; the intelligent vehicle access control system and the RFID system can be integrated into a double-frequency detecting system. A vehicle access control system adopting a frequency band of 13.56 MHz and an RFID technology adopting a frequency band ranging from 840 MHz to 940 MHz are integrated into the same antenna. According to the intelligent vehicle access control system, the frequency of 840 MHz to 940 MHz can be represented in a forcing function, so that the vehicle access control system and the RFID technology are easy to integrate.
Description
Technical field:
The utility model relates to a kind of intelligent vehicle gate control system, particularly a kind of intelligent vehicle gate control system based on ultrahigh frequency radio frequency identification (RFID) reader.
Background technology:
RFID technology is one and utilizes radiofrequency signal to carry out contactless two-way communication, automatically identifies destination object and obtains the wireless communication technology of relevant information data.Along with scientific and technical progress, RFID has related to the various aspects of people's daily life, is widely used in the fields such as industrial automation, business automation.
And intelligent vehicle gate control system is to utilize supermatic electromechanical equipment and computer technology to carry out safe and effective management to parking lot, community etc.Reduce to greatest extent the loss that personal expenditures and human error cause, greatly improved security and service efficiency.
But what vehicle access control system adopted is the frequency range of 13.56MHz, and the frequency range of the ultrahigh frequency reader-writer that we use is at 840MHz～940MHz.For vehicle, if use this two kinds of frequency ranges simultaneously, also need to purchase two electronic tag card, the utility model provides a kind of method based on the compatible 13.56MHz frequency range of ultrahigh frequency radio frequency identification (RFID) reader frequency range well to solve this problem.
Utility model content:
Technical problem to be solved in the utility model is: build rfid interrogator, make it can receive the microwave signal of 840-940MHz frequency range, the microwave signal of vehicle access control system 13.56MHz frequency range can be received again, when vehicle process gate inhibition, microwave signal can be automatically identified.
For this reason, the utility model provides a kind of intelligent vehicle gate control system of combination ultrahigh frequency reader-writer, comprising: vehicle recognition card and roadside equipment.
Vehicle recognition card is placed in the windshield position, side of vehicle, and when vehicle enters the workspace of read write line, the wagon detector in read write line detects vehicle by information, by sky alignment car card, sends " inquiry message "; Car card receives that inquiry message therefrom obtains Power supply simultaneously, the information of vehicles that is about to store in car card is modulated on the signal receiving, and returns to read-write controller, and read-write controller is received after the answer signal of car card by antenna, through netting twine, pass to supervisory computer database, compare judgement, by query processing result and instruction, by netting twine, return to read-write controller, if be loaded with the legal vehicle of car card, system will be sent automatic clearance instruction, open railing, automatic releasing driving; As be without car truck, system is sent automatic interception instruction, and railing is closed, by operator on duty, is processed.
Native system efficiently prosthetic carry out vehicles while passing management.
Accompanying drawing explanation:
Fig. 1 be native system structure as figure;
Fig. 2 be native system flow process as figure.
Embodiment:
As shown in Figure 1, native system comprises vehicle recognition card and roadside equipment; Described roadside equipment comprises antenna, high frequency rfid interrogator, Computer Database and railing; When vehicle enters the workspace of read write line, the wagon detector in read write line detects vehicle by information, by sky alignment car card, sends " inquiry message "; Car card receives that inquiry message therefrom obtains Power supply simultaneously, the information of vehicles that is about to store in car card is modulated on the signal receiving, and returns to read-write controller, and read-write controller is received after the answer signal of car card by antenna, through netting twine, pass to supervisory computer database, compare judgement, by query processing result and instruction, by netting twine, return to read-write controller, if be loaded with the legal vehicle of car card, system will be sent automatic clearance instruction, open railing, automatic releasing driving; As be without car truck, system is sent automatic interception instruction, and railing is closed, by operator on duty, is processed.
Claims (1)
1. the intelligent vehicle gate control system based on ultrahigh frequency radio frequency identification (RFID) reader, comprising: vehicle recognition card and roadside equipment; Described roadside equipment comprises antenna, high frequency rfid interrogator, Computer Database and railing; When vehicle enters the workspace of read write line, the wagon detector in read write line detects vehicle by information, by sky alignment car card, sends " inquiry message "; Car card receives that inquiry message therefrom obtains Power supply simultaneously, the information of vehicles that is about to store in car card is modulated on the signal receiving, and returns to read-write controller, and read-write controller is received after the answer signal of car card by antenna, through netting twine, pass to supervisory computer database, compare judgement, by query processing result and instruction, by netting twine, return to read-write controller, if be loaded with the legal vehicle of car card, system will be sent automatic clearance instruction, open railing, automatic releasing driving; As be without car truck, system is sent automatic interception instruction, and railing is closed, by operator on duty, is processed; The microwave signal of described antenna reception 13.56MHz and 840-940MHz scope, read-write controller is the information comparison receiving, and sends to reply instruction and determine whether to allow to pass through.
