Above-mentioned voice alarm circuit is made up of two normal opened contacts of phonetic alarm and intermediate relay ZJ 1; One of them is connected on two normal opened contact switches of intermediate relay ZJ 1 between power supply and the phonetic alarm, the break-make of control phonetic alarm power supply, another normal opened contact switch is connected between the voice system and power supply of phonetic alarm, controls switching on and off of voice system.
Normal opened contact one end of time relay sj 1 joins in the power positive end of above-mentioned electric control lockset and the control loop, the extreme power cathode that directly connects of the power-of electric control lockset.
The beneficial effects of the utility model are: owing to increased safety control between general electric control lockset and power supply, for not meeting all unlocking action of connecting the electric control door lock power supply, all can not open electric control lockset, improve the security performance of electric control door lock greatly.This apparatus structure is simple, easy to operate, safe and reliable, and cost is low effective, is applicable to the occasion of various use electric control door locks.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is described further.
Fig. 1 is the utility model functional-block diagram;
Fig. 2 is the utility model circuit theory diagrams;
Fig. 3 is a warning circuit schematic diagram of the present utility model.
The specific embodiment
Referring to above-mentioned accompanying drawing.ZJ1, ZJ2 are auxiliary reclay.Be about 10 seconds the actuation time of time relay sj 1 (electric control lockset possesses the charged time of opening, and can adjust arbitrarily).Be about 10.5 seconds the actuation time of time relay sj 2.It is 10.5 seconds-10 seconds=0.5 second that electric control lockset possesses the charged duration of opening, and this time can be adjusted arbitrarily as required.Be about 20 seconds the actuation time of time relay sj 3, and promptly circuit reset time is 20 seconds, and this time also can be adjusted arbitrarily.SK1 is the start button switch, and MK1, MK2 are linked switches.MK1 connects electric control lockset, as the trigger switch of electric control lockset power supply; MK2 connects intermediate relay ZJ 2, as the action triggers switch of ZJ2.Make the outage of this device during the MK2 action, electric control door lock is disconnected and can not opens owing to power supply.
When opening the door, press start button SK1, make intermediate relay ZJ 1 action and self-sustaining, three normal opened contact closures of ZJ1, starting switch is by short circuit, positive source gives intermediate relay ZJ 1 power supply by the ZJ1 circuit-closing contacts, and the power supply and the voice switch of phonetic alarm are connected simultaneously, send the voice suggestion sound.Under intermediate relay ZJ 1 energising back action and self-sustaining situation, time relay sj 1, SJ2, SJ3 are also simultaneously charged.SJ1 often opens the time-delay contact closure after 10 seconds, presses linked switch MK1, MK2 this moment, and the current supply circuit of connecting electric control door lock because of MK1 makes electric control lockset possess the condition of opening.Because MK2 moves closure simultaneously, intermediate relay ZJ 2 actions, its ZJ2 normally closed contact disconnects, and control loop loses the power supply power supply and is in involution state soon.Because of the delay of the time relay, so control loop lags behind electric control lock and open about 0.1 second～0.3 second of time reset time.
Press start button SK1, after the time relay action, if send out switch MK1, MK2 not according to second line of a couplet movable contact, after about 10.5 seconds, time relay sj 2 normally closed contacts disconnect, cause time relay sj 1 dead electricity, its time relay SJ1 often opens time closing contact and is in off-state, and the electric control lock loop does not possess the charged condition of unblanking.After time relay sj 3 actions, the circuit involution.Random time outside 10 seconds～10.5 seconds all can not be opened electric control door lock.
Electric control door lock must move in the time difference of predefined unblank time started and the duration of unblanking section by the door lock owner, promptly opens in the time difference of time relay SJ1 and time relay sj 2 actions.Set by artificially adjusting in advance the actuation time of time relay sj 1 and SJ2, and can change.The unscheduled duration can not unblank.
Alarm signal is self-control recording or music module, thus must the door lock owner could grasp the electric control lock uncaging time, but electric control lock actuation time can only be 0.5 second or shorter, other staff can't open electric control lock by the principle of originally unblanking, to reach security purpose.
This routine used electric control lock lockset is originally as the commercially available prod.
