Abstract
The utility model belongs to the technical field of control devices, and particularly relates to a mobile phone remotely-controlled unlocking device with realizability in remotely-controlled unlocking, convenience in use, good anti-theft effect and simple structure. The mobile phone remotely-controlled unlocking device comprises a telephone I, a telephone II, a control box and an electric control lock, and has the structural key points that a power supply circuit, an audio-frequency decoding chip, a driving chip and a relay are arranged in the control box; and the telephone II, the audio-frequency decoding chip, the driving chip, the relay and the electric control lock are connected in sequence.
Description
Technical field
The utility model belongs to the control device technical field, relates in particular to a kind of mobile phone remote unlocking apparatus.
Background technology
Existing door lock generally needs the people to pass through key unlocking, if house-owner people stays out, and have owner's friend or relative to visit this moment, then can not enter the house, and owners such as need return to unblank, and are not very convenient therefore.In addition, existing door lock operated by rotary motion has keyhole, has stayed the possibility of unblanking to stealer.
Summary of the invention
The utility model is exactly at the problems referred to above, and a kind of remote unlocking of realizing is provided, easy to use, good anti-theft effect and mobile phone remote unlocking apparatus simple in structure.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises phone I, phone II, control box and electric control lock, is provided with power supply circuits, audio decoder chip in its structural feature control box, drives chip and relay; Described phone II, audio decoder chip, driving chip, relay, electric control lock link to each other successively.
As a kind of preferred version, the model of audio decoder chip described in the utility model is MT8870D.
As another kind of preferred version, the model of driving chip described in the utility model is ULN2003.
The utility model beneficial effect
1, can realize remote unlocking, easy to use
The utility model comprises phone I, phone II, control box and electric control lock, is provided with power supply circuits, audio decoder chip in the control box, drives chip and relay; Phone II, audio decoder chip, driving chip, relay, electric control lock link to each other successively; Phone II receives the signal of squeezing into of phone I, and signal is inputed to the audio decoder chip, and the audio decoder chip sends control signal after with signal decoding, and control signal makes the actuating of relay through driving after chip amplifies, thus the state of control electric control lock.So the utility model can be realized remote unlocking, and is easy to use.
2, good anti-theft effect
The utility model adopts electric control lock, does not have keyhole, stealer is had no way of doing it, so the utility model good anti-theft effect.
3, simple in structure
The utility model comprises phone I, phone II, control box and electric control lock; Member is few, connects simply, so the utility model is simple in structure.
Description of drawings
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with the drawings and the specific embodiments, the utility model is further elaborated.Should be appreciated that the specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model circuit theory diagrams.
The specific embodiment
As shown in the figure, the utility model comprises phone I 4, phone II 3, control box 2 and electric control lock 1, is provided with power supply circuits, audio decoder chip in the control box 2, drives chip N and relay K; Described phone II 3, audio decoder chip, driving chip N, relay K, electric control lock 1 link to each other successively.
The model of described audio decoder chip is MT8870D.
The model of described driving chip N is ULN2003.
As Fig. 2, civil power through by being the electric control lock power supply, is audio decoder chip, driving chip N and relay K power supply behind the process voltage stabilizing sheet T behind transformer P, the rectifier bridge S successively again.The signal that phone II 3 sends is added to the input that drives chip N after the decoding of audio decoder chip, drive chip N and play the effect that strengthens signal, the output of driving chip N comes control relay K action by the variation of high-low level, and then the switch of control electric control lock 1.
Below in conjunction with a description of drawings course of action of the present utility model
At first phone II 3 is set to the auto-pickup pattern, and the earphone jack of phone II 3 is linked to each other with the audio decoder chip; Make a phone call for phone II 3 with phone I 4, after entering auto-pickup, if press 1 key of phone I 4, electric control lock 1 and power connection, electric control lock 1 is opened, if want electric control lock 1 to close, can be by 2 keys of phone I 4.
Above content is to further describing that the utility model is done in conjunction with concrete preferred implementation; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the definite protection domain of claims that the utility model is submitted to.
