Description

A kind of RFID wireless entrance guard device

Technical field

This utility model particularly relates to a kind of RFID wireless entrance guard device。

Background technology

At present, gate control system is widely used in security system。Be provided with in the porch of building gate control system can the entrance of controllers, especially when safe important place is guarded without operator on duty, it is possible to effectively prevent lawless people from entering。And existing gate control system is due to the limitation of design, safety has much room for improvement。Meanwhile, existing gate control system does not record the essential information of gate inhibition, such as gate inhibition geographical position, cell information etc., therefore, those skilled in the art need a kind of RFID gate control system of offer badly, can not only improve the safety of gate control system, can record the essential information of gate inhibition simultaneously。

Utility model content

The purpose of this utility model is in that for above-mentioned the deficiencies in the prior art, it is provided that a kind of RFID wireless entrance guard device。

The technical solution of the utility model is achieved in that

A kind of RFID wireless entrance guard device, including radio-frequency card and access control unit, radio-frequency card connects access control unit, radio-frequency card includes the first communication interface, rf read-write device and antenna, first communication interface connects rf read-write device, rf read-write device connects antenna, access control unit includes card reader interface, real-time clock, I/O interface, stand-by power supply, main control unit, second communication interface, computer server, remote alarm interface and monitoring interface, card reader interface, real-time clock, I/O interface, stand-by power supply, second communication interface, remote alarm interface and monitoring interface connect main control unit respectively, second communication interface connects computer server。

Main control unit adopts P87LPC767 singlechip chip。

First communication interface and second communication interface all adopt SP485R interface chip。

Rf read-write device adopts MFRC500 read write line chip。

This utility model beneficial effect:

This utility model is reasonable in design, easy to use, and implementation cost is low, safety is good, it is possible to can gather door body information by RFID tag, simple and convenient, also by storage device can ratio more complete and consult access personal information comprehensively, thus reaching to improve the effect of the safety of gate control system。

Detailed description of the invention

Consult shown in Fig. 1, a kind of RFID wireless entrance guard device of the present utility model, including radio-frequency card 1 and access control unit 2, radio-frequency card 1 connects access control unit 2, radio-frequency card 1 includes the first communication interface 3, rf read-write device 4 and antenna 5, first communication interface 3 connects rf read-write device 4, rf read-write device 4 connects antenna 5, access control unit 2 includes card reader interface 6, real-time clock 7, I/O interface 8, stand-by power supply 9, main control unit 10, second communication interface 11, computer server 12, remote alarm interface 13 and monitoring interface 14, card reader interface 6, real-time clock 7, I/O interface 8, stand-by power supply 9, second communication interface 11, remote alarm interface 13 and monitoring interface 14 connect main control unit 10 respectively, second communication interface 11 connects computer server 12。

Main control unit adopts P87LPC767 singlechip chip。

Rf read-write device adopts MFRC500 read write line chip。

Access control unit receives the data message from radio-frequency card by card reader interface, then pass through the microcontroller data message to receiving to be analyzed, to judge that whether corresponding RFID information is legal and is delivered to computer server, obtain management host switch door order by RS485 interface。Access control unit has gate inhibition and sets up defences, withdraws a garrison and shield alarm function, can support various electric control door lock, supports black, two kinds of working methods of white list。

Radio-frequency card launches RFID information by read write line, and carries out wireless two-way communication between access controller, to facilitate system to be operated automatically。

MFRC500 operating frequency is 13.56MHz, supports the communication protocol of all layers of ISO14443A, and the antenna that operating distance is closer can be driven by the internal transmitter of this chip, without outside active circuit。This chip is applicable to in-plant operation, and sphere of action, up to 0-100mm, has interrupt handling capacity flexibly, has unique product ID, it is possible to automatically detect the type of paralleling microprocessor interface, and meanwhile, user can start configuration feature by programming。

Communication interface on computer server converts this communication data to Transistor-Transistor Logic level through SP232 chip, then again through the conversion of SP485R chip, this Transistor-Transistor Logic level is changed into the level needed for RS485 to carry out the transmission of data, completes the communication between computer and gate control system。

Embodiment provided above is better embodiment of the present utility model, only it is used for this utility model is conveniently described, not this utility model is done any pro forma restriction, any art has usually intellectual, if in the scope without departing from the carried technical characteristic of this utility model, utilize the Equivalent embodiments that the done local of this utility model disclosed technology content is changed or modified, and without departing from technical characteristic content of the present utility model, all still fall within the scope of this utility model technical characteristic。
