Abstract

The utility model belongs to a break alarm anti-theft door which is composed of a main control module, a defense area condition signal driver 2, a network signal converter 3, a detection signal driver 4, an acoustic-optic alarm circuit 6, a communication dialing drive circuit 7 and a door body 8. The utility model is characterized in that the door body 8 is provided with a defense area conducting wire return circuit 5 which is composed of a return circuit, and the return circuit is composed of a conducting wire network. If the door body 8 is destroyed by prying, drilling, breaking, etc., a defense area conducting wire return circuit S of the door body 8 is disconnected and a host machine is driven to give an alarm. The utility model has the advantages of low wrong alarming rate, high reliability and low cost.

Description

Breaking alarming formula security door

The utility model relates to a kind of security door, particularly a kind of security door of breaking alarming formula.

Because the public security problem is increasingly serious, people pay attention to more for antitheft, seem important more for the antitheft of gate, and at present a large amount of security doors that use all are to adopt the thickness of reinforcing door, and it is antitheft perhaps to adopt reinforcing bar to make iron gate, another kind of mode is exactly to adopt more firm door lock, this dual mode all is the antitheft of passive type, if just the robber adopts the mode of sled, brill to be easy to door is opened, there is the shortcoming that theftproof performance is poor, can not report to the police in the security door that uses now.

The purpose of this utility model is to provide a kind of breaking alarming formula security door of the superior performance that just can at once report to the police when the robber wants that destroying door enters the house.

The purpose of this utility model can realize by following measure:

The utility model is made of main control module, defence area status signal driver, networking signal converter, detection signal drives device, communication dialing drive circuit, sound light alarming circuit, door body, and it is characterized in that: the door body is provided with defence area wire loop circuit.

The mesh that defence area wire loop circuit is made up of the lead that is arranged on a body and the doorframe constitutes.

The utlity model has that reliability height, rate of false alarm are low, pick-proof, anti-drilling, advantage that price is low.

Referring to accompanying drawing, Fig. 1 is a functional-block diagram of the present utility model, and Fig. 2 is a signal flow graph of the present utility model, and Fig. 3 is a schematic circuit of the present utility model, and Fig. 4 is an arrangement of conductors structural representation of the present utility model.

The utility model will be further described below in conjunction with accompanying drawing:

Referring to Fig. 1,1 is that main control module, 2 is that defence area status signal driver, 3 is that networking signal converter, 4 is that detection signal drives device, 5 is that defence area wire loop circuit, 6 is that sound light alarming circuit, 7 is the drive circuit that dials of communicating by letter.

Referring to Fig. 2, the output that the detection signal that the signal output part of main control module 1 sends is transported to detection signal drives device 4 inputs, process detection signal drives device 4 is transported to defence area wire loop circuit 5, the signal of defence area wire loop circuit 5 outputs is transported to defence area status signal driver 2, the output signal of defence area status signal driver 2 is input to the input of main control module 1, and the alarm signal of main control module 1 outputs to the sound light alarming circuit 6 and the dialing drive circuit 7 of communicating by letter respectively.

Referring to Fig. 3, main control module 1 is made of microcomputer chip CPU, and detection signal drives device 4 can be made of latch 74LS373, defence area status signal driver 2 can be made of input buffer 74LS244, and networking signal frequency conversion device 3 is by D4, D5, C3, R3, R4, N2 constitutes.

Referring to Fig. 4,8 is the door body, and S is the lead that is distributed on the body 8.

The utility model is made of main control module 1, defence area status signal driver 2, networking signal converter 3, detection signal drives device 4, sound light alarming circuit 6, communication dialing drive circuit 7, door body 8, it is characterized in that: be provided with defence area wire loop circuit 5 at door body 8.

The mesh that defence area wire loop circuit 5 is made up of the lead that is distributed in a body 8 constitutes.

Referring to Fig. 3, the utility model is after system's energising, export the data input pin of a high level detection signal from the data-out port of main control module 1 to detection signal drives device 4 (latch 74LS373), cushion through latch 74LS373, high level signal is transported to the base stage of triode N1 from the data output end of latch 74LS373, make triode N1 conducting, high level signal is through the emitter stage of triode N1, behind the networking lead S by defence area wire loop circuit 5, through networking signal frequency conversion device 3, high level signal becomes networking, defence area status signal, again signal is transported to the data input pin of networking, defence area status signal driver 2 (input buffer 74LS244), after amplifying, the defence area status signal is transported to the data input pin of main control module 1 from the data output end of 74LS244, and main control module 1 is made corresponding processing according to the level height state of defence area status signal.

Main control module 1 constantly sends detection signal, level state to S loop, networking, defence area scans detection, when the networking lead S of the defence area wire loop 5 on being arranged at a body 8 is disconnected, the sensed current signal that main control module 1 sends is by behind the triode N1, can not form the loop through networking lead S, being equivalent to loop S is disconnected, there is not current signal to be input to networking signal converter 3, make signal converter 3 output high level in networking to main control module 1, after main control module 1 is received high level signal, send signal and be input to sound light alarming circuit 6, send the sound and light alarm signal; Perhaps issue a signal to communication dialing drive circuit 7, forward public telephone network to, be connected to by public telephone network on the phone or beeper of setting, also can be connected to 110 alarm stations.

The utility model is when practical application, with main control module 1, defence area status signal driver 2, networking signal converter 3, detection signal drives device 4, sound light alarming circuit 6, communication dialing drive circuit 7 usefulness box bodys are assembled together as the main frame of burglar alarm, with lead the security door wire loop circuit 5 on main frame and the door body 8 is coupled together, the networking lead S of security door wire loop circuit 5 is by certain density and rule, mode with the networking is distributed in a body, on doorframe and the lock body, when outside destroy door body or doorframe and lock body, as sled, bore, roll etc., then must destroy the lead S that is distributed on the body 8, the loop is disconnected, thereby cause the warning of main frame, if the normal key of door that adopts opens the door, then main frame can not reported to the police.

Be provided with automatic fault 1 li of main control module and detect, N1 is breakdown when triode, can detect automatically by the fault self-checking function of main control module 1, and points out by suggestion device.
