A personnel access identification system comprises active electronic tags worn by personnel, 2.4G planar directive antennas, reader-writer modules and application modules, wherein the 2.4G planar directive antennas, the reader-writer modules and the application modules are in 2.4G wireless connection; the personnel access identification system is developed on the basis of the active electronic tags, uses 2.4G free communication frequency band, applies subdivision control over wireless signal reception intensity, has the characteristics of high identification accuracy, high signal update speed and the like which can meet the requirement for real-time performance, can increase the capability of discriminating the personnel access situation to a large extent, and can offer historical data query.
Description
Technical field
The present invention relates to a kind of electronic access control system based on RFID technology, belong to Internet of Things applied technical field.
Background technology
Personnel pass in and out the personnel that recognition system is mainly used in special area and pass in and out automatic management, and can carry out comprehensive assessment to the personnel's whereabouts in region, avoid because personnel cause security incident extremely, and provide historical data to ex-post analysis.It is integrated application microelectric technique that personnel pass in and out recognition system, information sensing technology, and the sci-tech product of ICT (information and communication technology), is that real-time follow-up personnel distribute, the powerful guarantee of supervisor's behavior.Traditional personnel pass in and out management and need manually go to swipe the card with personnel, beat fingerprint energy, and turnover is inconvenient, are judged and are carried out in addition by low frequency wake-up mode, inconvenience is installed, and degree of accuracy are low.
Summary of the invention
Problem for existing, the invention provides a kind of electronic access control system based on RFID technology, can carry out situation to the personnel in regulation region and carry out accurately, monitors in real time.
The technical solution used in the present invention is:
An electronic access control system based on RFID technology, its structural feature is:
Comprise the active electronic label that personnel wear, with by the dull and stereotyped directional antenna of the wireless 2.4G that is connected of 2.4G, reader/writer module and application module;
Active electronic label, for identified person identity ID, is regularly outwards launched the ID message of determining power; The region of the dull and stereotyped directional antenna of 2.4G for stipulating range of receiving, and by the active electronic label wireless signal receiving, be delivered in reader/writer module; Reader/writer module is used for receiving wireless signal, and by Ethernet, information is delivered to application module; State and statistics that application module is used for storing data and in the mode of figure and data list, shows current personnel's turnover.
Preferably, described reader/writer module comprises: the Receiver Module that sensitivity can software be adjusted, Men Nei or outdoors read write line;
Sensitivity can software adjustment Receiver Module for controlling the sensitivity of radio frequency reception, controlled the size of signal range of receiving, can software adjustment; Door in or outdoors read write line be that the ID message that has added positional information is sent to application module and further processes for distinguishing the residing location status of current active electronic label.
Preferably, described antenna is the dull and stereotyped directional antenna of 2.4G, and radiofrequency signal is received and possesses obvious directivity.
Preferably, described application module comprises application software and database; Application software is for the treatment of the relation between electronic tag ID and personnel and show that current personnel pass in and out state; Data source is used for storing turnover data, enquiry of historical data; Application software is connected to database and Men Nei or outdoors between read write line.
The beneficial effect of technical solution of the present invention is:
Described personnel pass in and out recognition system and develop based on active electronic label, use the free communications band of 2.4G, utilization is controlled the segmentation of reception of wireless signals power, the feature of have that identification accuracy is high, signal update soon can requirement of real time, lifting personnel pass in and out the discriminating power of situation largely, and the inquiry of historical data can be provided.
Accompanying drawing explanation
Fig. 1 is the structural representation of the electronic access control system based on based on RFID technology of the present invention.
Embodiment
According to drawings and embodiments the present invention is described in further detail below.
As shown in Figure 1, the described electronic access control system based on based on RFID technology, comprises the active electronic label that personnel wear, with by the dull and stereotyped directional antenna of the wireless 2.4G that is connected of 2.4G, reader/writer module and application module;
Active electronic label, for identified person identity ID, is regularly outwards launched the ID message of determining power; The region of the dull and stereotyped directional antenna of 2.4G for stipulating range of receiving, and by the active electronic label wireless signal receiving, be delivered in reader/writer module; Reader/writer module is used for receiving wireless signal, and by Ethernet, information is delivered to application module; State and statistics that application module is used for storing data and in the mode of figure and data list, shows current personnel's turnover.
Described reader/writer module comprises: the Receiver Module that sensitivity can software be adjusted, Men Nei or outdoors read write line;
Sensitivity can software adjustment Receiver Module for controlling the sensitivity of radio frequency reception, controlled the size of signal range of receiving, can software adjustment; Door in or outdoors read write line be that the ID message that has added positional information is sent to application module and further processes for distinguishing the residing location status of current active electronic label.
Described antenna is the dull and stereotyped directional antenna of 2.4G, and radiofrequency signal is received and possesses obvious directivity.
Described application module comprises application software and database; Application software is for the treatment of the relation between electronic tag ID and personnel and show that current personnel pass in and out state; Data source is used for storing turnover data, enquiry of historical data; Application software is connected to database and Men Nei or outdoors between read write line.
When system is installed, Men Nei and being installed separately according to on-site actual situations outdoors, avoids intersection region as much as possible, further adjusts the dull and stereotyped direction of directional antenna of 2.4G and the sensitivity of received RF module, reaches the optimum condition that personnel pass in and out judgement.Interior or outdoors time through moving into one's husband's household upon marriage when carrying personnel's electronic tag, the ID message that active electronic label regularly sends is arrived by the dull and stereotyped alignment antenna reception of 2.4G, application module is by the still different I D of read write line outdoors of Men Nei, can but separate the residing position of current personnel, and then in user interface, make figure demonstration and positional information is deposited in database, be convenient to carry out the inquiry of historical record.
Above-noted persons pass in and out recognition system and develop based on active electronic label, use the free communications band of 2.4G, utilization is controlled the segmentation of reception of wireless signals power, the feature with energy requirement of real time such as identification accuracy are high, signal update is fast, lifting personnel pass in and out the discriminating power of situation largely, and the inquiry of historical data can be provided.
