Description

Electronic cipher control type burglar alarm

The utility model relates to a kind of electronic cipher control type burglar alarm.

Prior art is of a great variety, and function is different.General technical specifications requirement according to standard GB 12663-90 anti-theft and alarm device, usually possess the instantaneous warning of invasion, emergency alarm, tamper warning and delayed alarm, the latter is that adjustable the entering of 0-40S postpones and 100S fixedly goes out time delay, and " ripe steathily " phenomenon is taken place.In addition, prior art often has to be failed to report or wrong report affected by environment etc., cause unnecessary loss and terrified, and anti-damage ability is relatively poor, or is removed easily, destroys, or when external power is cut off or have a power failure, can not carry out work usually, poor reliability.

The purpose of this utility model is to overcome above shortcoming, provide a kind of eliminate time-delay and fail to report, wrong report and the very few high-reliability electronic cipher control formula burglar alarm of power consumption.

The utility model is to implement like this: will have the electronic cipher controller that can encode and be arranged on outdoors, and link to each other with the sensor that is laid in the appropriate location, electronic control circuit and antiwithdrawal device respectively, and implement alarm by photoelectric alarm circuit; In addition, on power consumption, power with external power supply at ordinary times, and to establishing the charging of two groups of direct supplys in installing, in case outage then keep long operate as normal by it automatically, and trigger bistable relay with the pulse current of the electronic cipher controller that is provided with and change duty.

Provide specific embodiment of the utility model below in conjunction with accompanying drawing.

Fig. 4. the electronic cipher controller coupling arrangement.

Fig. 5. the structural representation of portion outdoors of electronic cipher controller.

Fig. 6. the relative scheme of installation of electronic cipher controller door internal and external parts.Wherein: 1. sensor, 2. electronic control circuit (main frame), 3. external power; 4. sound light alarming circuit, 5. external end device, 6. electronic cipher controller; 7. line, 8. casing, 9. alarm lamp; 10. reset button, 11. pilot lamp, 12. external power receptacles; 13. controllable silicon, 14. relays, 15. electronic switches; 16. regulator block, 17. error code electronic switches, 18. betal cans (lid); 19. keyboard; 20. the doorbell button, 21. locksets, 22. working station indicators; 23. detaching-proof protection device; 24. hummer, 25. pyroelectric sensors, 26..

The utility model is arranged on the electronic cipher controller 6 on the door by the sensor 1 that is installed in door (window) frame side, is made up of electronic control circuit 2, sound light alarming circuit 4 and external terminal 5 and external power 3 that casing 8 contains, as depicted in figs. 1 and 2.

As Fig. 6 and 5, wherein being oppositely arranged on the inside and outside suitably electronic cipher controller 6 of height of door is by code keypad 19, betal can (lid) 18, lockset 21, and bell button 20, working station indicator 22 constitute the M of part outdoors of electronic cipher controllers 6, and the inner N of corresponding door then is by self check and distress call button K ₁, coding K switch, password direct supply V ₂, diode D ₇Constitute with the detaching-proof protection device 23 (being connected outdoors) of F that is connected across electronic cipher controller 6 and E end; M and N electronic cipher controller dimerous can carry out 1-16 position coded combination; input password when going out; make on the keyboard 19 relay indicating light 22 bright; warning device is on the alert; must import proper password when opening the door, three inputs of accumulative total error code (warning, the non-state of alert) is promptly sent sound and light alarm.The betal can 18 wherein and the main effect of lockset 21 are to prevent other people random keypad.If accident has little time by the distress call button, this line 7 can be broken the purpose that reaches distress call.Electronic cipher controller 6 (G, F end) and integrated package Ic ₂The electronic switch 15, the semiconductor diode D that constitute ₅, D ₄And bistable relay 14 is formed burglar alarm duty (warning, non-warning) change-over circuit, as Fig. 3, in the conversion and control in working order, the change of duty is had the bistable relay J of auto-lock function by the positive sign indicating number trigger action of electronic cipher controller 6, and do not need to keep work with big electric current, prolonged standby power supply V in the machine greatly ₁Working time, when external power 3 is cut off, still can keep long work, make it more reliable, safety.When the common port of relay J and a connect, enter the state of alert, the working station indicator 22 on the electronic cipher controller 6 is bright, and when common port during with the b connection, red light goes out, and withdraws from the state of alert.Because this electronic cipher controller 6 is arranged on outdoors, has eliminated the operation delay of general alarm device, thereby has improved the generation of anti-damage ability and " ripe steathily " phenomenon, and is more safe and reliable.

Sensor 1 links to each other with F, G end through electronic cipher controller 6, and as Fig. 4,3, the output line 7 of electronic cipher controller 6 links to each other with electronic control circuit 2, and sensor is a magnetic switch or tongue tube; The detaching-proof protection device 23 of above-mentioned electronic cipher controller 6, the simplest is a lead in the betal can 18 that is laid in, and also can be a pressure-active element, alarms when sled is got and destroy electronic cipher controller.Said external end device 5 is more powerful loudspeakers, and this loudspeaker is connected with the output terminal of sound light alarming circuit 4.

Above-mentioned electronic control circuit (main frame) 2 mainly be by with integrated package Ic ₁The sound light alarming circuit HA that error code electronic switch 17 input ends join, through reset button 10, silicon-controlled device 13, with resistance R ₂, capacitor C ₁The instantaneous warning circuit of invasion with sensor 1 formation; And by error code electronic switch 17 (integrated package Ic ₁) with the diode D that links to each other with its output terminal ₆Error code warning circuit during the continuous several input error cipher instruction that constitutes is formed.The latter makes electronic cipher controller recur fluctuating signal when continuous three input error cipher instructions, triggers and reports to the police, and automatically resets behind the 40S.The A to G of above-mentioned electronic control circuit 2 () the corresponding respectively electrical connection of end.Wherein E, F end and detaching-proof protection device 23, G, F end is connected with sensor 1, A ' BCDK ' G corresponding with electronic cipher controller positive pole, error code output, working station indicator 22, just yard export and the coding and the negative pole of scrambler join.

As another embodiment, three contact H, G, a place in the electronic control circuit [2] of said apparatus can also connect or add other multiple sensors, as pyroelectric sensor 25 devices such as infrared sensing such as grade.

External power 3 of the present utility model also can be through regulator block 16, resistance R via socket 12 power supplies that are arranged on the housing 8 ₁, diode D ₁To password power supply V ₂Charging is by resistance R ₈, green LED forms the external power supply indication, and through R ₇Current limliting is to direct supply V ₁Charging, diode D ₁After oppositely ending, by resistance R ₆Red LED forms the direct supply indication.When under-voltage by transistor BG ₁, BG ₂, diode D ₃And resistance R ₃, R ₄, R ₅Under-voltage display circuit with pronunciation device 24 formations.When external power has a power failure, direct supply V ₁To the complete machine power supply, keep operate as normal.

In sum, characteristics of the present utility model are to have eliminated time-delay, have avoided " steathily ripe " phenomenon Generation, have tamper, destruction-proof function and distress call warning, three error code alarms, from The several functions such as checking functions demonstration, and little power consumption, though have a power failure or cut off the electricity supply after still can keep In the long duration, work. Therefore reasonable in design, cheap, reliability is high, is family The anti-theft appliance that front yard and enterprises and institutions are desirable.
