Certainly, in other embodiments of the invention, RF spot and the address of collision detection communication can also be determined according to other modes, such as directly agreement is used for RF spot and the address of collision detection communication, or generates the RF spot and address that communicate for collision detection according to other algorithms of both sides' agreement.
It should be noted that, in the present invention, the RF spot for collision detection communication which kind of mode that don't work is determined and address, all must be different from main radio-frequency unit and between radio-frequency unit for the RF spot of proper communication and address.For guaranteeing this point, the radio frequency band of collision detection communication can be given for, make the radio frequency band for collision detection communication different from the radio frequency band for proper communication.
Step a15, main radio-frequency unit receives collision detection result by radio-frequency channel;
Step a16, main radio-frequency unit carries out anti-collision process according to the collision detection result received in step a12.
Wherein, main radio-frequency unit has magnetic emitter, has magnetic receiving trap from radio-frequency unit.Such as, main radio-frequency unit can be magnetic channel radio frequency card reader, can be magnetic channel radio frequency SIM card from radio-frequency unit.The structure of radio-frequency card reader and radio-frequency SIM card can be as shown in Figure 2.
Fig. 2 is the structural drawing of radio-frequency card reader and radio-frequency SIM card.As shown in Figure 2, radio-frequency card reader 100 comprises microcontroller 103, radio-frequency (RF) receiving and transmission module 101, radio-frequency antenna 102, and magnetic signal generating means 104.Microcontroller 103 processes the information that radio-frequency (RF) receiving and transmission module 101 is received and dispatched, and produces magnetic channel data information.Radio-frequency (RF) receiving and transmission module 101 is connected with microcontroller 103 and radio-frequency antenna 102, for transmitting and receiving radiofrequency signal.Radio-frequency antenna 102 is for detecting and radiate radio frequency signals.Magnetic signal generating means 104 is connected with microcontroller 103, sends the magnetic channel data information that microcontroller 103 produces.

Step b13, the radio-frequency SIM card 302, the radio-frequency SIM card 303 that are in radio-frequency card reader 301 conflict area (namely near field communication range) all receive collision detection information;
Step b14, the collision detection information received and local information compare by radio-frequency SIM card 302, discovery comparative result is consistent, then radio-frequency SIM card 302 is left intact, continuous business, and radio-frequency SIM card 303 is through comparing, find the collision detection information that receives and the local information of self inconsistent, then radio-frequency SIM card 303 judges to control oneself to result in conflict, and radio-frequency SIM card 303 will continue the conflict response message sending 20ms on the RF spot and address of conflict;
In the present embodiment, when receiving the radio-frequency SIM card of collision detection information through comparing, when judging that the local information of self is consistent with the local information in collision detection information, adopt the mode be left intact, the collision detection of this situation is not as a result, main radio-frequency unit (such as radio-frequency card reader) receives conflict response message on radio-frequency channel.In other embodiments of the invention, when radio-frequency SIM card is through comparing, when judging that the local information of self is consistent with the local information in collision detection information, radio-frequency SIM card also can send notice or message by radio-frequency channel to main radio-frequency unit (such as radio-frequency card reader), informs that this radio-frequency SIM card of main radio-frequency unit does not conflict.That is, when collision detection result is not for conflicting, radio-frequency SIM card both can by not sent the mode of any response message, also can be loaded with the not notice of conflicting information or the mode of message by sending, this collision detection result of conflicting informs main radio-frequency unit (such as radio-frequency card reader).
Step b15, when radio-frequency card reader 301 receives conflict response message, then judges to there occurs conflict in conflict area, disconnects the radio-frequency SIM card 302 of present communications.
Otherwise, if radio-frequency card reader 301 Stochastic accessing is radio-frequency SIM card 303, the collision detection process that radio-frequency SIM card 303 also will be done as above.
