Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of radio-frequency recognition system as shown in Figures 1 to 6, including receiver 1 and remote controler 7.
Receiver 1 includes:
First control unit 2 is carried out with remote controler 7 to code, and real-time reception remote controler 7 requests code；First control is single
The command information control random number generation module 3 that member 2 is received according to signal receiving module 5 generates random number and sends out random number
Remote controler 7 is given, is received with 7 successful matching of remote controler after the correct random number of the feedback of remote controler 7, successful matching is followed by by distant
Control device 7 distribute area code, area code be assigned after by code protective module 4 is no longer received remote controler 7 to code request.
Random number generation module 3 generates random number and is sent to remote controler 7 by signal transmitting module 6；
To code protective module 4, receive area's code of the distribution of remote controler 7, and within a specified time no longer receives matching for remote controler 7
To request；It can be 30 minutes to the specified time of code protective module 4 as a kind of specific embodiment.
Signal receiving module 5, for receiving 7 command information of remote controler；
Signal transmitting module 6, for the random number generated in random number generation module to be sent to remote controler 7；
Remote controler 7 includes:
Second control unit 8 is carried out with receiver 1 to code, and the second 8 pairs of control unit receives what responder module 10 received
The receiver 1 of first response is carried out to code；
Instruction module 9 is sent, pairing request is issued to all receivers 1 and the random number received is sent back into receiver 1；
Responder module 10 is received, the random number that receiver 1 issues is received, receive first receiver 1 is issued
Random number is as pairing object；
Input/output module 11 is electrically connected with the second control unit 8, is that the receiver 1 of successful matching distributes area's code, area's code
It can be operated by the key of remote controler 8.
Energy supply control module 12 controls the supply and charging of 7 power supply of remote controler.
Indicating lamp module 13, for showing the working condition of the second control unit 8.
Working principle: by input/output module 11, press remote controler 7 to code key, remote controler 7 sends periphery lamps and lanterns
Pairing request, pairing request can divide 16 grades, closer to the receiver 1 of remote controler, more readily receive.When receiver 1 receives
After pairing request, receiver 1 generates 16 different random numbers, and is delayed after T1 milliseconds and does response, remote controler 7 to pairing request
After receiving first random number response, the response after automatic shield, by pressing number 1~8, with connecing for specified first response
Receive the ID of device 1.It is interior at 30 minutes not receive new pairing request after receiver 1 receives successfully, and normally grasping
The pairing request of other remote controlers 7, locking receiver 1 and remote controler 7 are not received under work.
Each remote controler 7 can distribute 8 area's codes, can be individually operated to the receiver 1 of each area's code, can also be with one
Play operation.The process of area's code assignment to receiver 1 is known as to code.Such as it is following to code process:
A remote controler has 8th area code to be divided into A1, A2......A7, A8；
B remote controler has 8th area code to be divided into B1, B2......B7, B8；
The current area's code of No. 1 receiver is B1, and No. 2 receivers are B2 when proparea code, then can integrally be controlled using B remote controler
1, No. 2 receiver is made, also can be controlled separately 1, No. 2 receiver.If necessary to use No. 1 receiver of A remote control control, then need
No. 1 receiver is carried out to code.By to code can taking human as No. 1 receiver is changed to the area A3 code or other areas code.It has changed
Cheng Hou, B remote controler will no longer control No. 1 receiver, and only A remote controler just can control.
The workflow of receiver 1 the following steps are included:
Step 1: 1 real-time reception signal of receiver, and signal instruction is decomposed, corresponding operation is carried out by instruction.
Step 2: being stranded in order to realize faster to code, and caused by solving because of 1 receiving intensity difference of receiver to code
Difficulty is added to code protective module 4, no longer responds other pairs of code instructions in 30 minutes to the successful receiver of code 1, that is, improve
Guarantee that code efficiency, each receiver 1 can be completed to code again.
Step 3: in order to distinguish different receivers 1, each receiver 1 has a random number, different receivers
1 has different random numbers.
Step 4: the random number answer signal of receive first receiver 1 is sent back to receiver 1 by remote controler 7, really
The receiver 1 matched before settled with remote controler 7.
Step 5: when the random number that receiver 1 receives is consistent with included random number, indicate current bin 1 with it is distant
Control 7 successful matching of device.
Step 6: the receiver 1 of successful matching waits remote controler 7 to assign area's code to it.
Step 7: completing to code, receiver 1 is protected no longer to receive other remote controlers 7 in 30 minutes code protective module 4
To code request.Every time to the receiver 1 after code success do not participate in next time to code, guarantee is quick to code in this way, and
Omission is not had.
The workflow of remote controler 7 the following steps are included:
Step 1: sending pairing request instruction, notify all receivers 1 for receiving this instruction that will carry out operating code.
Step 2: if representing current all receivers 1 without any response and being interfered to code completion or signal,
It may be selected to repeat the first step and terminate to code.
Step 3: send pairing request instruction every time, 1 complete response of receiver under normal condition, select first with
The receiver 1 of machine number response is used as matched target.
Step 4: choosing whether to need to update area's code of current receiver 1 as needed.
Step 5: passing through the button operation of remote controler 7, new district code is sent to matched receiver 1.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
