Description

Micro-multi-purpose cipher remote control formula burglar alarm

The utility model relates to a kind of burglar alarm.

Along with economic development, levels of substance improves constantly at present, and antitheft problem is more outstanding, antitheft still employing of people installed antitheft door, window more, the dress anti-theft net, car adds theftproof lock to be solved, but effect is not ideal, stolen phenomenon still happens occasionally, the passive infrared alarm that important departments such as finance use because of costing an arm and a leg, must connect AC power, wiring is installed complicated, so be difficult to extensively enter family.

The purpose of this utility model is exactly in order to address the above problem, and it is small and exquisite to have designed a kind of external form, and alarm sound is loud, need not external power supply, and simple installation, cheap, the micro-multi-purpose cipher remote control formula burglar alarm of good anti-theft effect.

The utility model technical solution:

A kind of micro-multi-purpose cipher remote control formula burglar alarm, it includes vibration trigger circuit, alarm control circuit, oscillator-amplification circuit and the warning circuit that boosts, and the vibration trigger circuit are by vibrative sensor AB, resistance R ₄, transistor V ₂Form, alarm control circuit is by transistor V ₁, resistance R ₃, capacitor C ₂, transistor V ₂Form, oscillator-amplification circuit is by [C (model can be KD9561), resistance R ₆, transistor V ₃Form, the warning circuit that boosts is made up of transformer T, super loud hummer HTD, it is characterized in that it also has one by resistance R ₁, inductance I ₄With diode VD ₁The burn out check circuit of forming reaches by dial P, ＂ E ＂ type metal slide plate Q, inductance L ₁, L ₂, L ₃The password wire remote control devices of forming, coaxial activity is connected with loop line plate inductance L below the dial P of 0-9 position ₁, L ₂, L ₃, and L ₂, L ₁, L ₃From inside to outside be followed successively by thimble structure and arrange, integral body is connected with ＂ E ＂ type metal slide plate Q below dial P, three contacts of this slide plate Q respectively with corresponding inductance L ₁, L ₂, L ₃Sliding contact, inductance L ₁With inductance L in the burn out check circuit ₄Series connection diode VD ₁Positive pole, VD ₁Positive pole pass through resistance R simultaneously ₁Meet power supply E, VD ₁Negative pole control circuit taking alarm in transistor V ₁Base stage input, inductance L ₃Meet transistor V with vibrative sensor AB in the vibration trigger circuit after connecting ₂Base stage, inductance L ₂Ground connection.

Size as the utility model alarm volume such as the matchbox, adopt small battery powered, it can treasure at automobile, motorcycle, in the backplate of power assist vehicle or under the cushion of bicycle, or be mounted on door and window, behind the proof box, stir the telepilot password and make it to enter the state of alert, after this antitheft thing is moved slightly, vibration, alarm promptly sends and continues 1 minute loud chimes of doom, also can be external fine enamelled wire form the anti-theft net and the orchard of window, the fish pond, pouity dwelling place, garden, the warehouse, the guard wire of material, as long as robber's invasion is bumped the disconnection line and can be sent warning at once, the utility model also can be carried, as meet robbery on the way, violence etc., as long as the pulling backguy is promptly reported to the police, loud chimes of doom makes the person of hatching a sinister plot become terrified at the news surely, the back is installed in the family also can provides earthquake alarm night, and the telepilot line also has the warning function of anti-trimming.The utility model is simple in structure, and volume is small, and is cheap, and not power consumption during warning is easy to install, and theftproof performance is good, and the anti-destructive height is with a wide range of applications.

Fig. 1 is a structural drawing of the present utility model.

Fig. 2 is an electrical schematic diagram of the present utility model.

As Fig. 1, the utility model upside has two core sockets, is used for plug-in sense L ₄, L ₄Can be shorting stub, be used for anti-snatch, anti-riot backguy and report to the police, draw back promptly and report to the police, also can change elongated enameled wire into, be used to form anti-invasion net, constitute wire break alarm.Avris of the present utility model is that a multiple cord connects the cipher remote control device.

As Fig. 2, the ＂ E ＂ type metal slide plate Q in the cipher remote control device is connected with dial P, and 0-9 item sign indicating number is arranged on the dial P, revolves three-sixth turn and can obtain 10 passwords.When ＂ E ＂ type slide plate Q forwards 0 bit code to, inductance L ₂With L ₃Open circuit, the vibration trigger circuit are closed.When forwarding the 1-8 bit code to, L ₂With L ₃Connect, the vibration trigger circuit are in the state of alert, L when forwarding 9 bit codes to ₂With L ₁Open circuit, burn out check circuit begin to report to the police, and the 9th bit code is the trap sign indicating number, with anti-error group.The burn out check circuit is when broken string, and resistance R 1 is with voltage process diode VD ₁Be added to transistor V ₁Base stage, make transistor V ₁, V ₂Conducting.IC sends alerting signal, and warning circuit is by V ₁, V ₂, C ₂, R ₃Form monostalbe trigger control, when AB is triggered connection, V ₂Conducting, IC work, alerting signal is through V ₃Amplify, transformer T boosts and promotes super loud hummer HTD afterwards, and its duration of reporting to the police is by C ₂, R ₃Size decision.
