Card reader is divided into the accurate locating card reader of TOA and RFID card reader, the accurate locating card reader of TOA described in the utility model, can receive, send TOA formatted data bag, with the common accurately location of realizing of the accurate positioning mark card of TOA, simultaneously also can receive, send RFID formatted data bag, jointly realize the RFID location with the RFID tag card.Tag card is divided into the accurate positioning mark card of TOA and RFID tag card, tag card described in the utility model is the accurate positioning mark card of TOA, can receive, send TOA formatted data bag, calculate tag card to the distance and bearing between the card reader, also can connect simultaneously sending and receiving RFID formatted data bag, jointly realize the RFID location 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 situations:
The first, the accurate positioning mark card of the accurate locating card reader of TOA and TOA, tag card send TOA form handshaking information to card reader, and card reader can be identified, and confirms as accurate station-keeping mode.
The second, the accurate locating card reader of TOA and RFID tag card, tag card send RFID form handshaking information to card reader, and card reader can be identified, and confirms as the RFID station-keeping mode.
The third, the accurate positioning mark card of RFID card reader and TOA, tag card send first TOA form handshaking information to card reader, and card reader can not be identified, and tag card switches to RFID form handshaking information, and card reader can be identified, 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 to card reader, and card reader can be identified, 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 identify, the RFID tag card only sends the handshaking information of RFID form, in case tag card enters the measurement range of card reader, card reader is replied tag card, the proof tag card is finished 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 sends RFID station-keeping mode confirmation to tag card, tag card receives that the backward card reader of confirmation sends locating information, if card reader is received locating information, represent that then this tag card is in the card reader surveying range, if card reader is not received locating information, then represent this tag card not in the card reader surveying range, finish the RFID location;
3) card reader sends accurate station-keeping mode confirmation to tag card;
4) tag card is received the accurate station-keeping mode confirmation of card reader, send for the first time locator data bag to card reader, after card reader is received the locator data bag first time, send immediately for the first time response message, and card reader is recorded and is received that the locator data bag is designated as T to sending for the first time time period of response message 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 for the first time time period of response message from sending for the first time to record tag card
1
5) card reader is sent for the second time locator data bag 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 that for the second time the backward card reader of locator data bag is sent for the second time response message, 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 Generation of information is 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 mode of operation and is selected, confirmed accurately to locate again or the RFID location after the mode of operation, 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 location 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 accurate distance between tag card and the card reader according to the time, if having two or more card reader simultaneously the range information of explicit identification card just can orient the positional information of tag card, finish accurate position fixing process.And the TOA distance-finding method has technological difficulties to be time synchronized, if error appears in time synchronized, the as a result phase missionary society that then measures is very large.As shown in Figure 1, the utility model is for stationary problem settling time, adopted the mode that the time period calculates, by tag card and card reader separately the mistiming of sending and receiving packet calculate distance, avoided the problem of time synchronized, result of calculation is accurate.
