Abstract

The utility model provides a mutual recognition apparatus for a key and a door lock or a door. The apparatus comprises a distance inductor installed on the key and another distance inductor installed on the door lock or door. The distance inductor on the key comprises a first wireless radio frequency transmitting-receiving module (2) and a control module; the first wireless radio frequency transmitting-receiving module (2) is connected with a first power supply (1) and a first indicator lamp (3); and the control module is connected with the first wireless radio frequency transmitting-receiving module (2). The distance inductor on the door lock or door comprises a second wireless radio frequency transmitting-receiving module (4) and a control module; the second wireless radio frequency transmitting-receiving module (4) is connected with a second power supply (6) and a first indicator lamp (5); and the control module is connected with the second wireless radio frequency transmitting-receiving module (4). In the utility model, paired distance inductors are respectively installed on the key and the door lock, so when the two enter into a predetermined range, they transmit signals and then give out light simultaneously; thereby two purposes are achieved: firstly, the user can find the key in his bag conveniently and quickly in dark; second, he can see the concrete position of the lockhole clearly and open the door.

Description

A kind of key and door lock or door be the device of identification mutually

Technical field

The utility model relates to a kind of key and door lock or the door device of identification mutually.

Background technology

In daily life, particularly working people went home in the evening of dark, and the more Ms of object in the bag especially looks in the bag key and the correct position of finding keyhole very inconvenient in the dark.

Summary of the invention

The utility model provides a kind of key and door lock or the door device of identification mutually.For reaching above-mentioned purpose, the utility model adopts following technological means:

Described distance sensing device comprises the distance-sensor that is contained on the key and is contained on the door lock or the distance-sensor on the door, described distance-sensor on the key comprises first radio frequency transceiving module 2 and the control module, described first radio frequency transceiving module 2 links to each other with first power supply 1 and first indicator lamp 3, described control module links to each other with first radio frequency transceiving module 2, described be contained on the door lock or door on distance-sensor comprise second radio frequency transceiving module 4 and the control module, described second radio frequency transceiving module 4 links to each other with the second source 6 and second indicator lamp 5, and described control module links to each other with second radio frequency transceiving module 4.

By above technological means, the utility model can be by installing the distance-sensor of pairing on key and door lock, in the distance that enters setting when both time, it is simultaneously luminous then to send signal mutually, reaches at first to find key and the clear and definite particular location that finds lockhole to open these two purposes of door under the environment of dark easily and fast from bag.

The specific embodiment

The utility model provides a kind of key and door lock or the door device of identification mutually, this device comprises the distance-sensor that is contained on the key and is contained on the door lock or the distance-sensor on the door, described distance-sensor on the key comprises first radio frequency transceiving module (key wireless transceiver) 2 and control module, described first radio frequency transceiving module 2 links to each other with first power supply 1 and first indicator lamp (LED lamp sheet) 3, described control module links to each other with first radio frequency transceiving module 2, described be contained on the door lock or door on distance-sensor comprise second radio frequency transceiving module (door lock wireless transceiver) 4 and control module, described second radio frequency transceiving module 4 links to each other with the second source 6 and second indicator lamp 5, and described control module links to each other with second radio frequency transceiving module 4.

Described be contained in distance-sensor on the key and be contained on the door lock or door on distance-sensor be provided with and its encryption and decryption device one to one, described encryption and decryption device comprised be located at the distance-sensor that is contained on the key and be contained in door lock or set identical unique cipher mode and discern bar code in the distance-sensor on the door.

Described be contained on the door lock or door on distance-sensor behind power supply opening, second radio frequency transceiving module 4 just sends the identification bar code after oneself the encryption at set intervals, such as transmission range is 5 ~ 6 meters, when on the key distance-sensor enters this range of transmission, first radio frequency transceiving module 2 is received the identification bar code after the encryption that this second radio frequency transceiving module 4 sends, decipher earlier, because identical cipher mode, can successful decryption, obtain the identification bar code before encrypting, and the identification bar code that will discern bar code and its internal record is compared, when both are consistent, then the control module in the distance-sensor is on the key lighted indicator lamp 3, and issue behind the identification bar code encryption that will control oneself be contained on the door lock or door on distance-sensor carry out the check and correction of same step, after its check and correction is correct, be contained on the door lock or the control module in the distance-sensor on the door is lighted second indicator lamp 5.

With reference to accompanying drawing.Comprise also in the accompanying drawing that key 7 and this distance-sensor of lockhole 8(are installed on the lockhole), described first indicator lamp 3 and second indicator lamp 5 are the LED lamp.

The utility model is used to radio frequency identification (RFID) technology to have the distance-sensor of recognition function.Described two wireless radio frequency modules all comprise antenna and Transmit-Receive Unit separately.Use distance-sensor one to one to limit the key of pairing and the mutual triggering relation between the door/door lock, have only the distance-sensor that mutual correspondence has been installed that light could take place and react.When soon getting home, have the prompting of indicator lamp on the door, such as a slight aperture, send the warm halation that welcomes home, also make things convenient for simultaneously under the environment of dark and from bag, find key and the clear and definite particular location that finds lockhole easily and fast.

The operating frequency of radio frequency transceiving module can be set in advance, and scope is from 200MHZ-500MHZ.

The above embodiment only is used to illustrate technological thought of the present utility model and characteristics, its purpose is being used those of skill in the art can understand content of the present utility model and is being implemented according to this, therefore can not only limit claim of the present utility model with present embodiment, be variation or the modification that all spirit that the utility model disclosed is done, still drop in the claim of the present utility model.
