The utility model comprises an electrical source, an actuating circuit, a time delay effect circuit, an alarm control circuit, an alarm circuit, etc. The utility model has the multi-function that the exact alarm is realized; after the alarm is actuated within one minute, the alarm is not given no matter which mode a man adopts to open the door; the alarm can not be given if a key is used to open door; the guest message-leaving and a bell functions are realized; the in-site alarm and the remote alarm are realized, and other functions are realized.
Description
Burglar alarm belongs to the electronic anti-theft alarm technique.
In the existing burglar alarm, active fire alarm and passive type warning two big classes are arranged usually, an emitter and a receiving trap are often arranged in the active fire alarm device, transmit after the invaded person reflection, be received device and receive and pushing executing mechanism after the signal Processing is sent alerting signal.This class warning device is owing to there is emitter, so one-piece construction more complicated, cost is than higher, in the passive type warning device, two types of warnings are also arranged usually, and a class is a sound, light is reported to the police, and it is after being accepted by sensor by invador's signal, conversion through electronic circuit, become sound, light signal is notified the guarder, and as CN2042983U, a class is shooting invador's a video, stay its crime criminal evidence, be convenient to scout and solve a case, or by the TV pickup technology, Direct observation and record be invador's crime video down as CN2042981U and CN8520985U, all belong to this class as world patent WO82/02099 instructions and antitheft closed-circuit television system etc., in these devices, in a word, circuit, the structure more complicated, cost is higher, be difficult for promoting the use, the functional reliability that has is not ideal enough, produces false alarm sometimes, or use reasons such as convenient not enough, make the enforcement aspect that certain difficulty be arranged.
The purpose of this utility model provides a kind of circuit, simple in structure, and diverse in function is safe and reliable, and anti-theft capability is strong, and is easy to use, and cost is low, implements to promote easy burglar alarm.
For achieving the above object, the utility model is taked following measure:
1. use AC and DC hybrid power supply, with people's contact portion, use 6 volts power supplies of direct current, in the 220 volts of power supplies of part use interchange of reporting to the police, also in parallel one group of 6 volts of dry cell in addition, as emergency standby power,
2. the design time-delay circuit that comes into force makes the operator can not report to the police in back 1 minute throwing to report to the police, so that the actions such as opening the door, go out, lock a door that allows him finish of abundant time is arranged,
3. use relay node control technology,, be designed to start-up circuit, alarm control circuit, warning circuit etc. in conjunction with elements such as button, microswitch, limit switch, news Chinese percussion instruments.
4. microswitch is installed in the automatic door lock, has designed key and opened the door and do not report to the police, otherwise the program of reporting to the police,
Now in conjunction with the accompanying drawings embodiment is given to describe in detail,
What Fig. 1 provided is the circuit diagram of embodiment, and its square frame 1 is that power unit adopts alternating current-direct current hybrid power supply mode, and control circuit adopts 6 volts of direct current supplys so that the fuselage microminiaturization, and guarantee not have the danger of electric shock, warning circuit can be realized distant place warning function with 220 volts of Alternating Current Power Supplies
