Abstract

The utility model provides a robbery protection alarm of an intelligent security door, which comprises a regulated direct-current power source, an infrared induced emission circuit and a signal receiving, processing and transmission circuit. The infrared induced emission circuit is formed in the way that an integrated circuit IC1 outputting square wave pulsed voltage is connected to both ends of an infrared ray photorectifier V1. The signal receiving, processing and transmission circuit is formed in that way that a phototriode V2 is connected with an operational amplifier integrated circuit IC2, and then is connected with an audio decoding integrated circuit IC3. The integrated circuit IC3 outputs low level to drive the next circuit to work. The integrated circuit IC2 conducts power magnification on the signal transmitted by the phototriode V2; triggering signal is accessed to the amplifier integrated circuit IC1 through connected capacitors. The integrated circuit IC1 is connected to the single chip memory voice recording and reproducing integrated circuit IC3 through the integrated circuit IC2 for modulation of signal. An outgoing feeder of the integrated circuit IC3 is connected to a telephone or other host computers. The utility model has novel structure, is usable, and is a novel robbery protection alarm for an intelligent security door.

Description

The burglar alarm of intelligent anti-theft door

Technical field

The utility model relates to a kind of antitheft door, especially a kind of burglar alarm of intelligent anti-theft door.

Prior art

In known technology, existing antitheft door mainly is a load voice guard on antitheft door, when door during by improper prying open, connects and sends alerting signal.But when the people when door is far away, can't hear alerting signal, thereby also just lose the meaning of burglar alarm, more do not reach the purpose of burglar alarm.

Summary of the invention

In order to overcome the deficiency of existing antitheft door technology, the utility model provides a kind of novel structure, new-type antitheft door easy to use, it is in case when running into antitheft door and being prized, and can automatically signal be sent to external call, mobile phone, beeper or alerting signal and accept OPS etc. and carry out long-distance alarm.

The technical scheme in the invention for solving the technical problem is: adopt constant voltage dc source to connect infrared induction radiating circuit and signal reception processing transmission circuit respectively, the infrared induction radiating circuit connects signal and receives the processing transmission circuit, signal receives the processing transmission circuit and is connected and fixed phone or other main frame again, and the infrared acquisition type phone of being formed sends the novel intelligent antitheft door burglar alarm of signal.Constant voltage dc source is connected the constant voltage dc source of being made up of filter capacitor and three terminal regulator by direct supply DC; The infrared induction radiating circuit is connected in infrared photodiode V1 two ends by the integrated circuit (IC) 1 of exporting square wave pulse voltage to be formed, and V1 launches modulated infrared light by photodiode; It is to connect audio coding integrated circuit (IC) 3 again behind the phototriode V2 concatenation operation amplification circuit IC2 to be formed by corresponding reception photodiode V1 infrared light that signal receive to be handled transmission circuit, impel next circuit working by integrated circuit (IC) 3 output low levels, integrated circuit (IC) 2 will be carried out power amplification by the signal that phototriode V2 carries, and publish in instalments the ripple transformation under promoting, trigger pip inserts amplification circuit IC1 through company capacitor C 2-3, connect monolithic memory speech recording and reproducing integrated circuit (IC) 3 through the integrated circuit (IC) 2 of modulation signal again by integrated circuit (IC) 1, the output line of integrated circuit (IC) 3 is linked on telephone set or other main frame.During use, the infrared induction emission circuit system is installed in the inboard doorbell position of antitheft door or other appropriate location, signal receives output line junction chamber internal fixation telephone set or other main frame of handling the transmission circuit system.Force open the door when illegally entering the room as the people, after being detected by infrared eye, automatically activate emission coefficient and send signal to receiving system, automatically pass through the telephone set or other main frame that are connected again through processing and amplifying, outwards dial fast to the mobile phone of setting, phone, pager and alerting signal reception and control machine etc., send alerting signal.Storage integrated circuit (IC) 3 can be stored 10 groups of above telephone numbers, and is the dialing silent, especially can dial at preceding group and transfer next sets of numbers automatically when obstructed, realizes outside remote alarms.

Because technique scheme is adopted in the utility model design, through testing on probation showing, it has novel structure, design innovation can carry out outside remote alarms, and can report to the police to indoor and outdoors simultaneously, report to the police rapidly, dependable performance, advantage such as easy to use can be widely used in family, bank, shop, warehouse etc. and carry out anti-thefting monitoring.

Description of drawings
