Abstract
In the invention, a programmable decode circuit is newly added into the indoor decode circuit of current-used remote-control door lock; a programmable encode remote control registering unit matching the said programmable decode circuit is installed at outdoor; using said outdoor remote control registering unit to control the state of the indoor programmable decode circuit.
Description
Technical field
Content of the present invention belongs to the Remote control electronic lock technical field, relates to a kind of remote control gate lock receiver, particularly a kind of remote control composite receiver of encrypting remote control remote-control registration key.
Background technology
Has only a work decoding circuit in the work receiver of known all kinds of remote control gate locks at present, because control circuit is arranged in the door, its remote-control registration key is to carry out the registration of remote-control key by the registration switch on the work receiver in the actuating doors, then can't directly contact the registration that registration switch carries out remote-control key outdoors, therefore tamper-proof the and theftproof performance of this door lock is very high.But a common problem of its existence is: in case remote-control key is all lost or damaged, then the just unrenewable remote control mode of user is opened door lock, this moment just must be by alternate manner as mode emergent unlockings such as employing mechanical keys, but, will make the theftproof performance of remote control lock be lowered to the level of mechanical lock like this because this type of mode of employing will be stayed the mechanical key hole on door.
Summary of the invention
The objective of the invention is to the problem that prior art exists is solved, so provide a kind of structural behaviour rationally, convenient and reliable operation, the emergent unlocking that can use a teleswitch can not reduce the remote control composite receiver of the encrypted remote control remote-control registration key of the antitheft and preventing destructing performance of remote control lock simultaneously again.
The technical solution that adopts is for achieving the above object: set up a codified decoding circuit on the decoding circuit of working in the door of known remote control gate lock, and designing a codified remote control Register that can be complementary with this codified decoding circuit outdoors, utilize the codified decoding circuit of this remote control Register in remote control gate outdoors, change the login state of former work decoding circuit in the remote control gate lock by this circuit, thereby reach the purpose of encrypting remote control registration key outdoors.
Practical structures of encrypting the remote control composite receiver of remote control remote-control registration key of the present invention is: former the establishing at remote control gate lock set up a codified decoding circuit that is made of codified decoding chip and on-off circuit on the work decoding circuit, wherein the signal input part of codified decoding chip connects with the signal output part that receives head, the signal output part of codified decoding chip is connected to the control end of on-off circuit, and the two ends of on-off circuit are connected to the registration signal end of work decoding chip and the electronegative potential of codified decoding circuit respectively.
The invention has the beneficial effects as follows: when the remote-control key of the remote control gate lock of antitheft door, proof box (cabinet), automobile door etc. is all lost or is damaged, can need not to unblank re-registering remote-control key in the mode of encrypting outdoors by the codified decoding circuit newly established with emergency modes such as mechanical keys, there is not lockhole on the door body, antitheft good, safe in utilization with preventing destructing performance, convenient.

Embodiment
Referring to Fig. 1, the remote control composite receiver of encrypting remote control remote-control registration key of the present invention comprises that door lock is former to be established work decoding circuit I and newly establish codified decoding circuit II two parts circuit.Wherein as the work decoding circuit I of known part by receive 4 and work decoding chip 1 constitute (the work decoding chip 1 in the present embodiment adopts PIC16F630), it receives the signal input part that a signal output part of 4 passes to work decoding chip 1, and the registration signal end (LZARN end) of work decoding chip 1 is connected to the circuit electronegative potential through registration switch 5.The codified decoding circuit II that sets up on work decoding chip 1 is made of codified decoding chip 2 and the triode 6 as on-off circuit, wherein codified decoding chip 2 adopts PT2272, shared one of this chip and work decoding chip 1 receive 4, in parallel and the D point of both signal input parts, the signal output part of codified decoding chip 2 is connected to the base stage of triode 6, and the collector and emitter of triode 6 is connected to the registration signal end of work decoding chip 1 and the electronegative potential of work decoding circuit I respectively.In concrete the enforcement, above-mentioned work decoding circuit I and codified decoding circuit II can be realized that also promptly a chip has codified decoding and work decoding two parts function by a mcu programming.Contain codified chip 3 (adopting PT2262) and emission key 7 at the codified remote control Register circuit shown in the accompanying drawing 2, A0～A11 is 12 coding pin of codified decoding chip 2 and codified chip 3 among the figure.
The course of work of the present invention is such: in the work decoding circuit I of Fig. 1, the mode of known remote-control registration key is that the J point is pulled to electronegative potential when making it closure by direct control registration switch 5, and work decoding chip 1 enters login state; In the codified decoding circuit II that increases, the collector H of triode 6 is connected with the J point, the base stage of triode 6 is controlled by the output of codified decoding chip 2, shared one of work decoding chip 1 and codified decoding chip 2 receive 4, both signal input parts are parallel to the D point, and the coding A0～A11 of codified decoding chip 2 can preestablish; On the coding pin A0～A11 of codified chip 3, set the coding identical in Fig. 2 circuit with codified decoding chip 2, when emission key 7 closures, codified remote control Register circuit sends coded signal, receive 4 received signal among Fig. 1 and be input to codified decoding chip 2 and decode, the decoding back is outputed to the base stage of triode 6 by codified decoding chip 2, triode 6 conductings also are pulled to electronegative potential with the H point, thereby make work decoding circuit I enter login state.
