Description

Interface drive for electric controlling door lock

The utility model belongs to the signal controlling technical field, relates to a kind of remote interface drive set of opening a plurality of electric control door locks of concentrating.

Present existing electric control door lock is general to adopt traditional signal control circuit, is multi-thread on-off circuit, i.e. circuit controls of a door lock, and N door lock just needs N+1 root lead to connect control.The shortcoming of this mode is that line is many, and the lead consumption is big.Even adopt general bus structures, also need three leads, one connects power supply, a ground connection, another is as signal transmssion line, and need distinguish the purposes of three lines, so also be not easy to construction.Simultaneously aspect signal drive circuit, generally adopt directly energising, with contact switch or promote electromagnetic coil with large power triode and unblank, not only consuming electric power but also burn coil easily, the fault rate height, application life weak point.

The purpose of this utility model is to provide a kind of electric control door lock interface drive set, and it can overcome above-mentioned the deficiencies in the prior art, with two not the bus of polarity finish and drive control and open a plurality of electric control door locks, its driving circuit structure is simple, and is safe and reliable.

The purpose of this utility model is achieved in that the code signal from main controller is connected to by diode D by two buses ₁, D ₂, D ₃, D ₄The polarity transformation circuits of forming, polarity transformation circuits lower extreme point A ground connection, upper extreme point B connects two circuits, and the one road is through resistance R n ₁Current limliting is to diode D ₅Positive pole, by diode D ₅Negative pole be connected to the positive pole of capacitor C n, the minus earth of capacitor C n is as dc supply; Another road is through resistance R n ₂Be connected to triode T ₃Base stage, triode T ₃Colelctor electrode connect the positive pole of capacitor C n, emitter stage is by resistance R n ₃Ground connection, this signal passes through by triode T ₃Behind the emitter follower of forming, by emitter stage through Rn ₄Be connected to the signal input part IN of decoder Un; Resistance R n ₅, Rn ₆With capacitor C n ₁, Cn ₂Be the clock oscillation element of decoder Un, the address input end A of decoder Un ₀～A ₈By manual coding, ground connection or connect the positive pole of capacitor C n; The control output end V of decoder Un _TThrough resistance R n ₇Connect the trigger end of controllable silicon G, the minus earth of controllable silicon G, anode connects the end of electric control lock coil L, and the other end of electric control lock coil L is received the positive pole of capacitor C n, constitutes an interface drive set by two total a plurality of electric control door locks of line traffic control thus.

Advantage of the present utility model is: adopted two not the bus of polarity transmit signal, by triode T ₃With diode D ₅Combination discrete pulse signal and power supply, make that this device circuit is simple, the consumption lead is few, construction is easily, and is easy to maintenance; Because the effect of storage capacitor Cn and controllable silicon G makes electric control door lock coil L can not switch on for a long time, protected coil to be difficult for scaling loss, thereby made whole device safe and reliable again, prolong application life.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Fig. 1 has showed from main controller and has sent code signal to interface drive set, thereby opened the structured flowchart of electric control door lock.

Encoder U with reference to Fig. 2 main controller adopts the MC145026 type, is connected to the A of encoder U from the address signal of main controller keypad lock storage output ₀～A ₈, resistance R _TC, R and capacitor C _TCBe the clock oscillator element, the transmission control end of encoder U is subjected to the control of keyboard switch, its data output end D ₀Through resistance R ₁With triode T ₁Base stage link to each other triode T ₁Grounded emitter, colelctor electrode passes through resistance R ₂Connect positive source, resistance R ₃A termination triode T ₁Colelctor electrode, another termination triode T ₂Base stage, triode T ₂Emitter stage through light emitting diode D _TGround connection, the current collection collection is by load resistance R ₄Connect positive source, resistance R ₅A termination triode T ₂Colelctor electrode, the other end is through diode D _FOutwards export pulse code signal.

Decoder Un with reference to Fig. 3 the utility model interface drive set can adopt the MC145028 type, is passed to by diode D by two buses from the code signal of Fig. 2 ₁, D ₂, D ₃, D ₄The polarity transformation circuits of forming, reversal lower extreme point A ground connection, upper extreme point B tells two circuits, and one the tunnel through current-limiting resistance Rn ₁To diode D ₅With storage capacitor Cn, as dc supply; Another road is through resistance R n ₂Be connected to triode T ₃Base stage, its colelctor electrode connects the positive pole of capacitor C n, emitter stage is through resistance R n ₃Ground connection, this road signal passes through by triode T ₃Behind the emitter follower of forming, by emitter stage through Rn ₄Be connected to the signal input part IN of decoder Un; The address input end A of decoder Un ₀～A ₈By manual coding ground connection, resistance R n ₅, Rn ₆With capacitor C n ₁, Cn ₂Be the clock oscillation element, the control output end V of decoder Un _TThrough resistance R n ₇But connect the trigger end of silicon G, the silicon controlled minus earth, the positive pole of its anode and capacitor C n is connected on the two ends of electric control lock coil L respectively, constitutes an interface drive set by two total a plurality of electric control locks of line traffic control.

Its course of work is such: by the instruction coded address signal that keyboard is keyed in, be transferred to the address end A of the encoder U of main controller after latches ₀～A ₈, can the volume scope be: 2 ⁹=512, as the instruction T that allows coding _E=0 send after, the output D of encoder U ₀Send coded pulse signal, through triode T ₁, T ₂Amplify with the dc source stack and be sent on the bus light emitting diode D _TIndicate working condition; Polarity transformation circuits in the interface drive set guarantees that B rectifies A end negative ground and receives this signal, by resistance R n ₁With diode D ₅Rectification, current limliting, capacitor C n filtering energy storage provides a direct current voltage; The signal of input is through triode T ₃Isolate and amplify the input IN that sends into decoder Un.After the corresponding to decoder Un of geocoding that sends with main controller receives this signal, the output V of this decoder _TExport a high level, trigger controllable silicon G conducting, capacitor C n provides the driving energy to electric control lock coil L immediately, and promptly door lock is opened, and after capacitor C n had been put electricity, it kept electric current because of resistance R n ₁Restriction, deficiency is kept controllable silicon G conducting and is turn-offed, when encoder allows end T _EAfter allowing blackout, capacitor C n is recharged again, waits for instruction next time.Thus, can open a plurality of electric control door locks by the keyboard Long-distance Control of main controller.
