Embodiment
In order further to understand feature of the present utility model, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to the usefulness of explanation, be not to be used for protection domain of the present utility model is limited.
As shown in Figure 1, for having the synoptic diagram of RFID radio frequency identification system now.Must follow the tracks of at one or more goods or other and to paste on object or insert one or more electronic tag 101, the workman holds RFID card-reading terminal 102 and reads data on the electronic tag 101 by less radio-frequency, subsequently with data transmission to supervisory computer 103, to carry out management work such as follow-up statistics, analysis.Therefore company manager can understand in time by supervisory computer 103 and produces dynamically, the undesirable product of tracking quality easily, thus help type of production enterprise promotes prouctiveness effectively, effectively reduces handling cost.But be wired connection between RFID card-reading terminal 102 and the supervisory computer 103, need manually wiring in advance, if the layout of office space need change, then need rewiring, labor intensive is many and work is complicated.In addition, data have only from the one-way transmission of RFID card-reading terminal 102 to supervisory computer 103, and RFID card-reading terminal 102 does not have storage and function of statistic analysis, and the workman can't understand data such as the workload, product details of oneself at any time.
Be illustrated in figure 2 as the radio frequency identification device embodiment that the utlity model has bidirectional data transfers and statistics.Be connected by wireless server 204 between RFID card-reading terminal 202 and the supervisory computer 203.RFID card-reading terminal 202 sends by wireless mode the data that read to wireless server 204.Wireless server 204 is collected from the data of one or some RFID card-reading terminal 202, then with these data forwarding to supervisory computer 203 to carry out follow-up statistical study.Being connected by interface conversion equipment 205 of wireless server 204 and supervisory computer 203 connects.
In a non-restrictive example, as shown in Figure 2, the serial ports of supervisory computer 203 increases RS232/RS485 converter 205, and wireless server 204 and supervisory computer 203 are realized communication by the RS485 bus then.The data of storage can transfer to RFID card-reading terminal 202 by wireless server 204 in the supervisory computer 203, carry out functions such as statistical study thereon.In this embodiment, the distance between wireless server 204 and the interface conversion equipment 205 can be for smaller or equal to 500 meters; Distance between interface conversion equipment 205 and the supervisory computer can be for smaller or equal to 1 meter.
In another indefiniteness embodiment, interface convertor 205 can adopt RS232/ Ethernet mode to connect, under this embodiment situation, distance between wireless server 204 and the interface conversion equipment 205 is smaller or equal to 1 meter, and the distance between interface convertor 205 and the supervisory computer 203 is smaller or equal to 100 meters.
Fig. 3 is an one exemplary embodiment of wireless server 204.Wireless server 204 comprises wireless transmit/receive units 306, communication interface 307 and relay indicating light 308, power supply 309, wireless transmit/receive units 306 is used for receiving the data that RFID card-reading terminal 202 is sent, and transfer to supervisory computer 203 by communication interface 307, to carry out follow-up statistical study.The data of storage also can transfer to wireless server 204 via communication module 307 in the supervisory computer 203, transfer to RFID card-reading terminal 202 through wireless transmit/receive units 306 then, to carry out follow-up statistical study.So, bidirectional data transfers and statistics have been realized.
Fig. 4 is an one exemplary embodiment of the utility model RFID card-reading terminal 202.RFID card-reading terminal 202 has wireless transmit/receive units 406, Card Reader slot 407, LED light 408, LCDs 409, power supply 410, central processing unit 411 and button 412.Central processing unit 411 is finished to the processing of various data messages with to the control and the operation of other each module.In a non-limiting example, RFID card-reading terminal 202 comprises two Card Reader slots 407, and one of them slot is used for connecting attendance card (being employee's work card), another slot is used for connecting the card of reckoning by the piece, so, supervisory computer 203 both can have been finished and reckon by the piece, and can realize work attendance again.Have logic control in the central processing unit 411, make RFID card-reading terminal 202 only the employee swipes the card login with the job number card after, just allow to read RFID electronic tag 201, carry out the work statistics of reckoning by the piece; This logic also makes behind system cut-off, promptly logs off automatically.Owing to have central processing unit 411, the RFID card-reading terminal can be preserved data, so RFID card-reading terminal 202 has interim storage attendance record and the function of the record of reckoning by the piece, and these records will be uploaded after radio communication is connected automatically setting up with supervisory computer 203.Therefore, even supervisory computer 203 not start as yet, the workman still can operate as normal and normal statistics workload.The data storage that RFID card-reading terminal 202 is read can be transferred to wireless server 204 by wireless transmit/receive units 406 simultaneously in central processing unit 411.Data in the supervisory computer 203 send to RFID card-reading terminal 202 via wireless server 204, and are kept in the central processing unit 411, to carry out follow-up statistical study.But workman's operation push-button 412 is checked various information, for example workload, product quality information etc. at any time.In an indefiniteness embodiment, button 412 has six buttons, wherein two all the other four functions are undetermined in order to turn over downturning key on the LCDs 409, in order to the usefulness of system extension function.The various duties of LED light 408 indications visually realize very eye-catching prompting can for the employee; In a non-limiting example, pilot lamp 408 have redness, green, yellow three, green is used to refer to attendance card and reads success, redness is used for the expression card of reckoning by the piece and reads success, yellow is that function is undetermined, so that the usefulness of system extension function.LCDs 409 shows various information with written form, and for example The result of statistics makes the employee obtain relevant information at a glance.
Fig. 5 is an one exemplary embodiment of the utility model LCDs 409, and as can be seen from Figure, in an indefiniteness was given an example, LCDs 409 can provide 2 row, and 8 Chinese characters of every row show.When inserting employee's attendance card in the Card Reader slot 407, LCDs 409 shows this employee's job number and name, and this information is issued supervisory computer 203 by wireless transmit/receive units 406.Behind the affirmation signal of receiving supervisory computer 203 feedbacks, the green light in the LED light 408 is lighted, can be started working with the indication employee.In another slot of Card Reader slot 407, insert the card of reckoning by the piece this moment, red colored lamp in the LED light 408 is bright, the code that while RFID card-reading terminal 202 is read in the card of reckoning by the piece is issued supervisory computer 203, supervisory computer 203 finds information such as corresponding money number, operation number and number of packages according to this code, and issue RFID card-reading terminal 202, be presented on the LCDs 409, extinguish red LED pilot lamp 408 subsequently.As it is unsuccessful to communicate by letter, and then red LED lamp Chang Liang with the prompting user, does not show above-mentioned information on the LCDs 409 at this moment.
Should be understood that above-mentioned detailed description to embodiment, can be improved or conversion those of ordinary skills according to the above description only in order to understand the utility model.So long as reach all improvement of this purpose and the protection domain that conversion all should belong to the utility model claims.
