Abstract
The utility model relates to the field of intelligent electronic locks, in particular to a remotely controlled electronic coded lock circuit. The electronic coded lock circuit comprises a modulator circuit, a transmitting circuit and a receiving circuit, wherein the receiving circuit comprises a diode, an operational amplifier, a wave shaping circuit, a band-pass filter, a shaping circuit, a center frequency setting module, a triode, a resistor and an output module. The electronic coded lock circuit has the benefits that 1, the electronic coded lock circuit can achieve remote unlocking and increase a corresponding unlocking distance greatly; the receiving circuit in a lock body can receive a 3-5m signal; the maximum distance can reach about 10m for a customization requirement of a special client; and 2, the problem of too short service life of an infrared electronic lock caused by the use of an infrared integrated receiving module is solved; the infrared receiving sensitivity is not reduced; and the whole current power consumption is not improved.
Description
Technical field
The utility model relates to intelligent electronic lock field, relates in particular to a kind of remotely-controlled electronic cipher lock circuit.
Background technology
Current infrared electronic lock, the infrared receiving unit in lock body, all adopts infrared integrated module to receive.Consider that infrared electronic lock is by powered battery, CPU needs timing infrared integrated receiver module is waken up and dormancy, causes the life-span of infrared integrated module lower, thereby affects the application life of whole electronic lock; Time one is grown in addition, and infrared receiving sensitivity also corresponding decline is a lot.
Infrared receiving unit in lock body is light sensation receiving unit, generally all adopts photosensitive tube; Transmission medium, generally adopts fiber optic conduction.Use this technology unlocking, significantly shortcoming be need point blank will launch key and Receiver aligning, could correctly unblank.In user's use procedure, brought larger inconvenience.
Utility model content
The utility model is to overcome above-mentioned weak point, object is to provide a kind of remotely-controlled electronic cipher lock circuit, this circuit has solved the existing too short problem of infrared electronic lock life-span because using infrared integrated receiver module to cause, and can realize at a distance and unblanking simultaneously.
The utility model is to achieve the above object by the following technical programs: a kind of remotely-controlled electronic cipher lock circuit, comprise modulation circuit, radiating circuit and receiving circuit, described receiving circuit comprises: diode, operational amplifier, whole wave circuit, bandpass filter, shaping circuit, centre frequency arrange module, triode, resistance, output module; Described modulation circuit is delivered to radiating circuit transmitting by data, and receiving circuit receives the data of radiating circuit transmitting; Described diode one end ground connection, the other end is connected with operational amplifier, operational amplifier is connected with whole wave circuit, whole wave circuit is connected with bandpass filter, bandpass filter arranges module with centre frequency, shaping circuit is connected, shaping circuit is connected with triode, triode also with resistance,, output module is connected.
As preferably, described modulation circuit adopts the square wave of 38KHZ to modulate.
As preferably, described radiating circuit adopts low-power consumption 430 special chips.
As preferably, described diode is infrared receiving diode.
The beneficial effects of the utility model are: 1, the utility model can be realized at a distance and unblanking, greatly increase the respective distance of unblanking, receiving circuit in lock body can receive the signal of 3-5 rice, and for particular client customized demand, maximum distance can arrive 10 meters of left and right; 2, solve because use infrared integrated receiver module to cause too short problem of infrared electronic lock life-span, do not reduce again infrared receiving sensitivity simultaneously, overall current power consumption does not increase yet.
Accompanying drawing explanation
Fig. 1: structural representation of the present utility model;
Fig. 2: the electrical block diagram of receiving circuit.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further, but protection domain of the present utility model is not limited in this:
Embodiment 1: as shown in Figure 1, a kind of remotely-controlled electronic cipher lock circuit, comprises modulation circuit, radiating circuit and receiving circuit, and described modulation circuit is delivered to radiating circuit transmitting by data, and receiving circuit receives the data of radiating circuit transmitting.
The mode of modulation, carries out AND-operation the carrier wave of data and certain frequency, can improve like this emission effciency and reduce power supply power consumption.Here adopt the square wave of 38KHZ to modulate.
There are at present a variety of chips can realize infrared emission, can be according to selecting to send different types of coding.Because emission system is generally used powered battery, this just requires the power consumption of chip very low, and chip is all designed in resting state, when having button to press, just to work mostly.The utility model adopts low-power consumption 430 ASIC-baseds, takes self-defined exclusive agreement to carry out secure transmission infrared light.Compare current light-operated lock encryption performance and have significantly lifting.
Receive information mode, adopt exclusive special-purpose receiving circuit to realize, and do not adopt infrared integrated receiver module on the market, thereby can oneself control the distance of opening the door of the light-operated lock of design, and can not increase current power dissipation.Described receiving circuit comprises: infrared receiving diode, operational amplifier, whole wave circuit, bandpass filter, shaping circuit, centre frequency arrange module, triode, resistance, output module; Described infrared receiving diode one end ground connection, the other end is connected with operational amplifier, operational amplifier is connected with whole wave circuit, whole wave circuit is connected with bandpass filter, bandpass filter arranges module with centre frequency, shaping circuit is connected, shaping circuit is connected with triode, triode also with resistance,, output module is connected.
Described in above, be specific embodiment of the utility model and the know-why used; if the change of doing according to conception of the present utility model; when its function producing does not exceed spiritual that manual and accompanying drawing contain yet, must belong to protection domain of the present utility model.
