Abstract

The utility model provides a knocking type coded lock device which is high in anti-jamming capability, is hard to damage and break, and can be used under the severe environment. The knocking type coded lock device consists of a door lock control circuit, a power supply device, an electric control lock and a vibrating sensor for detecting a knocking signal, wherein the power supply device, the electric control lock and the vibrating sensor are communicated with the door lock control circuit. The knocking type coded lock device is simple in structure, and convenient and reliable, thereby being suitable for various occasions where the entrance guard is needed.

Description

The percussive coded lock device

Technical field

The utility model relates to a kind of electronic door lock device.

Background technology

Existing have multiple action type with electric control lock as the gate inhibition of lockset, as: fingerprint capturer, button code keypad, remote controller, IC-card Card Reader etc.But, if fingerprint capturer finger totally just can not unblank, and easy stained with spread disease; The button code keypad become easily infected by greasy dirt and expose often by button, safety is lower; There is the shortcoming that leaves behind and need to change battery easily in remote controller; IC-card equally also exists and leaves behind easily and shortcoming such as card is perishable.So need improve to existing gate inhibition's mode of operation.

Summary of the invention

The utility model provide a kind of antijamming capability by force, not fragile, be difficult for cracking the coded lock device that can under adverse circumstances, use.

Take following technical scheme:

The percussive coded lock device, by door lock control circuit, supply unit, electric control lock and the vibrating sensor that is used to detect knocking constitute; Described supply unit, electric control lock and vibrating sensor all are communicated with the door lock control circuit.

Operating principle of the present utility model is as follows:

Vibrating sensor is installed on the door-plate, and when people knock door-plate with certain rhythm, the vibrations of door-plate will be converted into corresponding tempo signal by vibrating sensor, also is keying sequence and be transferred to the door lock control circuit.The door lock control circuit compares this keying sequence and preset password sequence, if both conform to, assert that then password effectively opens electric control lock, otherwise will reset in the default time, waits for the input of next keying sequence.

The utility model is simple in structure, convenient and reliable, can be fit to various needs and use gate inhibition's occasion to use.

Description of reference numerals: 1-door lock control circuit; The 2-supply unit; The 3-electric control lock; The 4-vibrating sensor.

The specific embodiment

Below in conjunction with drawings and Examples the utility model content is described further.

As shown in Figure 1, the percussive coded lock device of present embodiment, by door lock control circuit 1, supply unit 2, electric control lock 3 and the vibrating sensor 4 that is used to detect knocking constitute.In the present embodiment, supply unit 2 is the 12V battery.With common mounting means electric control lock 3 is fixed on the door-plate, and vibrating sensor 4 also is arranged on the door-plate.With supply unit 2 and door lock control circuit 1 be arranged on doorframe near, supply unit 2, electric control lock 3 and vibrating sensor 4 all are communicated with door lock control circuit 1.

The door lock control circuit 1 of present embodiment adopts the ATMEGA16L integrated package as main controlling element, and the circuit theory of door lock control circuit 1 as shown in Figure 2.For example need input password " 654321 ", knock door-plate with following method and get final product: knock continuously 6 times → pause → connection knock 5 times → pause → connection knock 4 times → pause → connection knock 3 times → pause → connection knock 2 times → pause → knock 1 time.The time interval of knocking continuously need be less than 0.4 second, and the time of pausing need surpass 2 seconds door lock control circuits and will be considered as and need re-enter between 0.4 second to 2 seconds.Knock 10 times continuously and represent digital " 0 ".

The utility model need not to carry any beginning recognition device, only need remember that password gets final product, and be difficult for being cracked.

Claims

1. percussive coded lock device is characterized in that: by door lock control circuit, supply unit, electric control lock and the vibrating sensor that is used to detect knocking constitute; Described supply unit, electric control lock and vibrating sensor all are communicated with the door lock control circuit.
