Abstract

The utility model relates to a super long-distance microwave RFID goods management system comprising a monitoring host computer, a monitoring program, a database, a TTS, at least two RFID antenna-containing reading heads supporting the 2.45GHz microwave frequency band, an RF label and a voice reporting device. Each reading head is respectively connected with the monitoring host computer by RS232 or RS485 and the RF label is embedded into the interior or the surface of the monitored goods. Each reading head carries out the real-time communication with the RF label in the microwave mode and transmits the collected RF label data to the monitoring host computer; and the monitoring program judges the data and then the monitoring host computer carries out voice reporting according to the judgment result. The goods management system can accurately monitor the state of goods and personnel managed by RFID in the range of 2 to 80m and also can carry out voice reporting on the dynamic state of distant people and goods moving at high speed; the system is especially suitable for the taking and returning of non-man watched goods, the goods checking, the electronic toll collection management system, the electronic license plates, the vehicle speed measurement and the airport logistics conveying belt, and the like.

Description

Overlength distance microwave RFID Articla management system

1, technical field: the utility model relates to a kind of overlength distance microwave RFID Articla management system.

2, background technology: RFID (Radio Frequency Identification radio frequency identification) technology reaches its maturity in the application of China, and application is very extensive, and market potential and economic potential are extremely huge.RFID uses and mainly is confined to decipherment distance and recognition accuracy two aspects at present.Aspect decipherment distance, the discernible coverage of super high frequency technique RFID generally reaches 0-10m, optimum distance is between 1-7m, effectively read distance in the 7m, surpass 6-7m with regard to occur skip easily, misread, the radio shielding problem, so be difficult to guarantee the accuracy that reads and the reliability of use in a lot of applications.The disclosed technical scheme of ZL200620119023.5 patent only can satisfy≤the closely application of 3cm, and need every monitored equipment all will place a monitor terminal, increased use cost greatly.And the related electronic labelling system of ZL200620014622.0 patent also can only solve the article automatic recognition problem in the 7m scope.So in farther distance such as more than the 10m, the ultrahigh frequency RFID application just occurs blank, lacks ripe especially product and application system.

3, summary of the invention: the purpose of this utility model is to propose a kind of personnel, article that can effective monitoring is managed in 2-80m scope, simultaneously its motion state is reported the overlength distance microwave RFID Articla management system of sound.

The purpose of this utility model is achieved in that overlength distance microwave RFID Articla management system is a kind of rfid system based on the microwave communication mode, comprises that RFID supervisory system, at least two can support the RFID of 2.45GHZ microwave working frequency range to contain antenna read head, radio-frequency (RF) tag and newspaper mixer.It is monitoring host computer, watchdog routine, database and the TTS of text-to-speech system that the RFID supervisory system comprises main frame.Each read head is connected by RS232 or RS485 mode with monitoring host computer respectively, and it is interior or surperficial that radio-frequency (RF) tag embeds monitored article.

Each read head carries out real-time Communication for Power by microwave mode and radio-frequency (RF) tag, the radio-frequency (RF) tag data that collect are delivered to monitoring host computer, judge by watchdog routine, monitoring host computer is reported sound according to judged result by the newspaper mixer then, thereby can judge identification to the personnel in 2-80m scope, the motion state of article, monitor.

Owing to adopt technique scheme, this Articla management system can not only effectively be monitored 2-10m scope RFID institute's article managed and personnel, and can accurately monitor the situation of institute's article managed, personnel in 2-80m scope, remote, the people of high-speed motion, thing dynamic situation are reported sound, be specially adapted to receiving, give back, item verification of unmanned article, the non-stopping toll administration system, electronic license plate, motor vehicle tests the speed, and use in places such as airport logistics travelling belt.

4, description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:

Fig. 1 is the structural representation of overlength distance microwave RFID Articla management system,

Fig. 2 is an overlength distance microwave RFID Articla management system newspaper sound mode synoptic diagram,

Fig. 3 is an overlength distance microwave RFID Articla management system signal flow graph.

5, embodiment: the utility model is further specified below in conjunction with drawings and Examples.

As shown in Figure 1, describe with the example that is applied as that adopts two read heads.The utility model comprises that 2 are supported the RFID of microwave frequency band to contain antenna read head A and B, radio-frequency (RF) tag, newspaper mixer, monitoring host computer and watchdog routine.Two RFID read head A, B are fixed on want in the article managed zone, interval 〉=4m between A, the B is connected to two RFID read head A, B on the com port of monitoring host computer by RS232 or RS485 mode then.Radio-frequency (RF) tag is embedded or puts into article or the surface that will monitor.

As shown in Figure 2, the newspaper sound is to transfer to newspaper mixer newspaper sound after being finished dealing with by the TTS of text-to-speech system on the monitoring host computer again, therefore can report the sound literal according to practical application needs editor, use to adapt under the different environment, can avoid mistake during article are received, given back under the unattended operation environment by the newspaper sound.

As shown in Figure 3, RFID read head A, B gather the state of radio-frequency (RF) tag in real time by microwave mode, and send the state of each label to monitoring host computer by RS232 or RS485 mode.Radio-frequency (RF) tag watchdog routine, database, TTS speech engine and newspaper interval preface are installed on the monitoring host computer.Watchdog routine is responsible for judging whether to report sound according to the motion state of label between A, B read head, and with data recording in database.Report sound if desired, then enable TTS speech engine processed voice, report sound by the newspaper mixer then by newspaper interval preface.

Illustrate: empty alert army bears the special mission of defendance flight air security, and every airplane flight needs all that empty alert to go up machine on duty, and needs to receive the instrument bag that a cover includes important security apparatus on ground before the machine of going up, and gives back instrument bag immediately behind the following machine.Receive and give back and to have taken great amount of manpower time and office resource, and to have occurred careless omission and mistake easily by manually carrying out strict registration statistics.When apparatus storehouse passage surpasses 10 meters width, adopt other modes Articla management system since discernible coverage do not reach and can't satisfy the demands.

Adopt the technical solution of the utility model, two microwave RFDI read head A, B are fixed in the apparatus storehouse, be connected with monitoring host computer; And radio-frequency (RF) tag placed in the instrument bag, it can not be taken out.Open watchdog routine, monitoring and the management that can receive, give back all instrument bag.RFID data order by collecting between two microwave read head A and the B, can judge instrument bag into and out of direction, if the A district senses label signal earlier, B senses behind the zone, is considered as out; Otherwise then be considered as into.By the TTS of text-to-speech system newspaper sound, just can after receiving equipment, report sound as " the Zhangjiang great waves are received the equipment outbound " immediately, the equipment of giving back is then reported sound " the Zhangjiang great waves welcome back ".The equipment person of receiving to oneself whether correctly receiving apparatus has accomplished to know what's what, and directorial area can realize unmanned.
