Description

The telephone automatic alarm device

The utility model relates to a kind of warning device, the especially a kind of hand-free function of phone and telephone automatic alarm device that redialing function sends alerting signal of utilizing.

Though it is varied that existing warning device has, mostly be onsite alarming greatly, this type of alarm is not only grabbed incessantly robber, can point out the robber on the contrary, allows it flee the scene rapidly.Though someone develops telephone alarm, promptly utilize phone outwards to give the alarm, but the startup of this type of alarm needs the people for carrying out, as owner not at the scene the time, can't start warning device work, and when house-owner people not the time stolen situation happen occasionally, therefore, existing warning device can not satisfy the current society in the communications facility develop rapidly.

The purpose of this utility model is to overcome the deficiency of prior art, the telephone automatic alarm device that provides a kind of mobile phone of carrying by phone in the room and owner or beeper to send alerting signal to the owner who goes out.

The utility model is realized by following technical proposal: it comprises magnetic switch, and the warning starter that is electrically connected with magnetic switch is characterized in that it also comprises the converter that is electrically connected with the Hands-free key and the redial key of warning starter and phone thereof.Described converter becomes piece IC2 to constitute by switch ic chip 1 with timely basis set, wherein there are three groups of switches switch ic chip 1 inside, and respectively by 9,10,11 foot control systems, first group of switch is by 9 foot control systems, 4,5 pin link to each other with phone Hands-free key two ends, as hands-free signaling switch; Second group of switch is by 10 foot control systems, and 15,2 pin link to each other with phone redial key two ends, as redialing signaling switch; The 3rd group of switch be by 11 foot control systems, 13,12 pin respectively with the time base integrated package IC2 5,1 pin link to each other, as the power switch of IC2,16 pin connect power supply, 6,7,8 pin ground connection.Reset terminal 4 pin of time base integrated package IC2 link to each other with power end 8 pin, power supply is provided by 12 pin of IC1,1 pin connects power cathode, trigger end 2 pin link to each other with state value end 6 pin, control end 5 pin connect capacitor C 6 and link to each other with 7 pin, by to the discharging and recharging the time of capacitor C 6, the switching time of control output end 3 pin, thereby the duty of control IC1.

The utility model compared with prior art has following advantage and good effect: because the warning starter is connected on the Hands-free key and redial key thereof of phone, and alerting signal is mail on the mobile phone or beeper that house-owner people carries by time-delay control, therefore, can be under the situation that the robber does not discover as yet outwards or to house-owner people send alerting signal, thereby effectively prevent stolen and can in time catch the robber of invasion.The utlity model has simple in structure, stable performance, reliable, characteristics such as long service life, real is novel generation burglar alarm, can be widely used in production and the life.

Fig. 1 is the circuit structure diagram of the utility model.

The embodiment that provides below in conjunction with accompanying drawing is described further the utility model, is not limited to this but hold within the utility model.

Dotted portion is within the utility model and holds among the figure, and remainder is to hold within the prior art.

After the energising, when magnetic switch K2 was closed, the warning starter was in the monitoring state, and the S end points is a noble potential, can not start IC1 and IC2 work.Have only when after K2 disconnects, making the S end points and can start their work for electronegative potential.

IC1 adopts the TC4053 integrated package, and there are three groups of switches its inside, and respectively by 9,10,11 foot control systems, first group of switch is by 9 foot control systems, and 4,5 pin link to each other with phone Hands-free key two ends, as hands-free signaling switch; Second group of switch is by 10 foot control systems, and 15,2 pin link to each other with phone redial key two ends, as redialing signaling switch; The 3rd group of switch be by 11 foot control systems, 13,12 pin respectively with the time base integrated package IC2 5,1 pin link to each other, as the power switch of IC2,16 pin connect power supply, 6,7,8 pin ground connection.

IC2 adopts the NE555 integrated package, constitute oscillatory circuit, be used to control the duty of IC1, its reset terminal 4 pin link to each other with power end 8 pin, and power supply is provided by 12 pin of IC1,1 pin connects power cathode, trigger end 2 pin link to each other with state value end 6 pin, and control end 5 pin connect capacitor C 6 and link to each other with 7 pin, by discharging and recharging the time capacitor C 6, the switching time of control output end 3 pin, thereby the duty of control IC1.

The course of work of the present utility model is: when input signal was noble potential, input pin 4,15,13 was connected with 3,1,14 pin respectively, and promptly control signal is unsettled, and input is isolated with output, and output is high-impedance state.When input signal is electronegative potential, be that magnetic switch K2 disconnects (this switch is installed on inlets such as door or window), input pin 4,15,13 respectively with 5,2,12 pin are connected, input signal enters from 11 pin, deliver to 8 of IC2 through 12 pin, 4 pin, start IC2 work, rigidly connect when logical at power supply, because 6 liang of terminal potentials of capacitor C can not suddenly change, therefore state's value end 6 pin are identical with 5 pin current potentials, be noble potential, IC2 is reset, and output terminal 3 pin are electronegative potential, this signal is delivered to 9 pin of IC1, make 4 of IC1,5 pin are connected, and start the work of phone Hands-free key, and power supply passes through resistance R 6 to capacitor C 5 chargings simultaneously, make the 10 pin time-delay of IC1 connect 15 pin that IC1 is controlled in the back, 2 pin are connected, thereby start the work of phone redial key, so that the phone number that will key in or paging station put through automatically, and to master alarm.IC2 internal discharge pipe conducting on the other hand, 7 pin become electronegative potential, 5 pin charge to capacitor C 6 by diode D5 and resistance R 8,2,6 pin current potentials reduce, IC2 is set, and this moment, output terminal 3 pin were noble potential, and this signal is delivered to IC19,10 pin, 4,5 pin and 15,2 pin are disconnected, phone Hands-free key and redial key are disconnected.After IC2 is set, internal discharge ends, 7 pin are unsettled, power supply passes through R7, D 4 to capacitor C 6 reverse charges (i.e. discharge), after 2,6 pin current potentials raise, IC2 is reset again, and output terminal 3 pin become electronegative potential again, and this signal is delivered to IC1 and phone Hands-free key and redial key connected once more send alarm call repeatedly.D1 is used to prevent that the noble potential of IC2 pin 3 from sealing in the S end points; D2 is used to guarantee that power supply passes through resistance R 6 and charges to C5; D3 is used to prevent that the noble potential of S end points from sealing in 3 pin of IC2; D4 guarantees that power supply charges to C6 by R8; D5 guarantees that power supply discharges to C6 by R7.
