Description of drawings
The description of drawings of the utility model is following.
Fig. 1 is the structural representation of the utility model and card reader;
Fig. 2 is the circuit diagram of tag card locating module;
Fig. 3 is tag card power module circuitry figure.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Based on the tag card of TOA range finding, the TOA accurate positioning mark card of said tag card for carrying out precision ranging based on the TOA distance-finding method includes tag card processor, tag card locating module and tag card power module,
The tag card processor is used for the tag card processing data information, and other module work of control tag card realizes the switching between park mode and the normal mode;
The tag card locating module sends response message, receives the locator data bag, calculates the time delay between sending, receiving, and time delay information is sent to card reader;
The tag card power module is for tag card provides working power.
Tag card is divided into accurate positioning mark card of TOA and RFID tag card; The said tag card of the utility model is the accurate positioning mark card of TOA; Can receive, send TOA formatted data bag; Calculate the distance and bearing between tag card to the card reader, also can receive, send simultaneously RFID formatted data bag, realize the RFID location jointly with the RFID card reader.Based on above setting, the utility model can compatible TOA range finding and RFID location.
Type with card reader and tag card is divided, and the utility model can be divided into 4 kinds of situation:
First kind, TOA accurately locatees card reader and the accurate positioning mark card of TOA, and tag card sends TOA form handshaking information and gives card reader, and card reader can be discerned, and confirms as accurate station-keeping mode.
Second kind, TOA accurately locatees card reader and RFID tag card, and tag card sends RFID form handshaking information and gives card reader, and card reader can be discerned, and confirms as the RFID station-keeping mode.
The third, the accurate positioning mark card of RFID card reader and TOA, tag card send TOA form handshaking information earlier and give card reader, and card reader can not be discerned, and tag card switches to RFID form handshaking information, and card reader can be discerned, and confirms as the RFID station-keeping mode.
The 4th kind, RFID card reader and RFID tag card, tag card send RFID form handshaking information and give card reader, and card reader can be discerned, and confirms as the RFID station-keeping mode.
Tag card is the accurate positioning mark card of TOA; Then alternately send TOA form handshaking information and RFID form handshaking information each 10 times; Respond then definite station-keeping mode if obtain card reader; Then continue alternately to send TOA form handshaking information and RFID form handshaking information if can't obtain the card reader response, the accurate positioning mark card of TOA initial default is for sending 10 TOA form handshaking information.The form of a handshaking information of per 10 switchings of the accurate positioning mark card of TOA; Guarantee that card reader can discern; The RFID tag card only sends the handshaking information of RFID form, in case tag card gets into the measurement range of card reader, card reader is replied tag card; The proof tag card is accomplished the measurement of region mode in measured zone.
The concrete grammar that the utility model positions is:
1) tag card sends handshaking information to card reader, and card reader is judged based on the accurate location of TOA or based on the RFID location, if the RFID location then changes step 2 over to), if accurately the location then changes step 3) over to;
2) card reader is sent RFID station-keeping mode confirmation to tag card; Tag card sends locating information to card reader after receiving confirmation; If card reader receives locating information, represent that then this tag card is between the card reader measurement zone in, if card reader is not received locating information; In representing that then this tag card is not between the card reader measurement zone, accomplish the RFID location;
3) card reader is sent accurate station-keeping mode confirmation to tag card;
4) tag card is received the accurate station-keeping mode confirmation of card reader; Send locator data bag for the first time to card reader; After card reader is received the locator data bag first time; Send response message for the first time immediately, and card reader is noted and is received that the locator data bag is designated as T to the time period of sending the response message first time for the first time
2, tag card is received the response message first time that card reader is sent, the locator data bag is designated as T to receiving the time period of response message for the first time from sending for the first time to note tag card
1
5) card reader is sent locator data bag for the second time to tag card, and receives the response message second time that tag card is beamed back, and the time period of response message is designated as T to the record card reader to receiving for the second time from sending for the second time the locator data bag
3, tag card receives for the second time and sends response message for the second time to card reader behind the locator data bag, the tag card record is designated as T from the time period that receives transmission
4, card reader is received the second time of tag card after the response message, tag card will record T
1And T
4The packet of information sends to card reader;
6) tag card is according to T
1, T
2, T
3And T
4Temporal information, substitution formula calculate between card reader and the tag card apart from d:
Wherein C is the light velocity;
7) calculate the range information of same tag card according to many card reader, main card reader calculates the azimuth information of tag card.
The utility model first step is carried out the mode of operation selection, has confirmed accurately to locate or the RFID location after the mode of operation again, and the RFID positioning system is based on the RFID radio frequency principle; Tag card is in the card reader measurement range; Card reader can be received locating information, shows that then tag card is positioned at surveyed area, can't further accurately locate again; The RFID technology generally is used for the work work attendance, confirms that whether the employee is in the perform region.And the TOA distance-finding method can calculate the accurate distance between tag card and the card reader according to the time, if there is the range information of the card reader while explicit identification card more than two or two just can orient the positional information of tag card, accomplishes accurate position fixing process.And the TOA distance-finding method has technological difficulties to be time synchronized, if error appears in time synchronized, the missionary society of phase as a result that then measures is very big.As shown in Figure 1, the utility model has adopted the time period calculation mode for stationary problem settling time, through tag card and the card reader mistiming computed range of sending and receiving packet separately, has avoided the problem of time synchronized, and result of calculation is accurate.
Said tag card also includes the tag card display module, is used for the explicit identification card information.
Said tag card also includes the tag card hummer, when tag card is received evacuation order, pipes.
Said tag card also includes the tag card pilot lamp, is used for the duty of explicit identification card.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of present technique scheme, it all should be encompassed in the middle of the claim scope of the utility model.
