Description

Automatic warning mobile phone

The utility model relates to the burglar alarm technical field.

The telephone automatic alarm system of one of existing burglar alarm mode is to adopt telephone to send warning message.Though this type of alarm has been realized to the alert letter of remote transmission.But it is because need telephone wire to connect, thus can be ineffective because of artificially being cut off telephone wire, make its reliability not high.And the place of telephone wire can't be set for some, and as: automobile, field etc., just can't realize telephone automatic alarm.

The utility model provides a kind of practical more more reliable than telephone automatic alarm system, and purposes is warning device more widely.

The utility model is to install an alarm control circuit of control mobile phone transmission warning message automatically on existing mobile phone machine basis additional, and alarm control circuit has a triggering signal input to be connected with various inductors.When alarm control circuit is subjected to the signal triggering of self-inductor, control circuit enters operating state, the control mobile phone automatically in a period of time continuously to guarder's mobile phone or automatic paging beeper or there is the landline telephone of caller identification to get phone, the guarder is known warning message by the telephone number of caller identification.Its alarm procedure as shown in Figure 1, wherein 1 is inductor; 2 is automatic warning mobile phone; 3 is telephone network; 4 for guarder's mobile phone or automatic paging machine or the caller identification landline telephone is arranged.

The advantage of the compared with prior art existing telephone automatic alarm system of the utility model simultaneously owing to do not need telephone wire to connect, makes it in contrast to prior art and has higher reliability, disguise and advantages such as convenience, purposes are wide are set.

Realize mode of the present utility model below in conjunction with description of drawings.

Fig. 2 is the alarm control circuit schematic diagram.C wherein ₁, R ₁, R ₂, D ₁Be the inductor signal input circuit; T ₁, T ₂, R _C1, R _B1, R _B2, R ₆, R ₇, R _C2, be bistable circuit; C ₂, D ₂, R ₃, R ₄Be the automatic zero set circuit; R ₈, D ₃, C ₃Be the alarm control circuit control impuls input circuit that quits work; D ₄, T ₃Be non-contact switch circuit; T ₄, T ₅, R _C4, R _B4, R _B5, R _C5, R ₁₀, C ₅Be monostable circuit; I is a frequency divider; Fraction frequency device input end F input is 1 second a clock pulse from cycle of mobile phone, and output H exports the cycle 2 ²The pulse of second, the output G output cycle is 2 ⁹The pulse of second; R _B6, T ₆, R _E6Be the start coupling circuit; T ₇, R _B7, R ₁₁For calling coupling circuit; K ₁Be mains switch; K ₂Be functional select switch; + E is the alarm control circuit working power;-E is a bias supply.

Be that sensitive switch is an example below with the inductor, and the course of work of the automatic warning mobile phone of contrast accompanying drawing 2 explanations: K is the normally opened contact of sensitive switch among Fig. 2, the positive source of alarm control circuit and signal input part A go between respectively on two of the normally opened contact end pin, and the warning mobile phone is in off-mode.When the thing of setting up defences is moved, touch sensitive switch, the normally opened contact closure, the A point obtains high potential among Fig. 2, through C ₁, D ₁Produce a positive pulse, T at the B point ₁Conducting, the bistable circuit upset, the saltus step of C point is a high potential, through D ₄At T ₃Base stage also saltus step is a high potential, T ₃Conducting, monostable circuit and frequency divider obtain power supply and devote oneself to work.Because the saltus step of C point is a high potential, through C ₄, D ₅On the D point, produce a positive pulse, the monostable circuit upset, entry time is about 3 seconds temporary stable state, on the E point, produce wide about 3 a seconds positive pulse, through the start coupling circuit, be transported to the on/off circuit of automatic warning mobile phone, make automatic warning mobile phone start.Constantly the generation cycle is 2 to frequency divider at H point output ²Pulse per second (PPS), by calling coupling circuit, constantly transmit and call signal and give the central processing unit of mobile phone (wherein first effective impulse is for accessing the telephone number pulse, remaining effective impulse is for calling pulse), make the warning mobile phone constantly get mobile phone from phone to guarder or automatic paging beeper.The G output output cycle of frequency divider is 2 ⁹The broad pulse of second (about 8.5 minutes) is in frequency divider operation to 2 ⁹Second, clock pulse was gone out now negative saltus step, triggered the bistable circuit upset, and the saltus step of C point is " 0 " current potential, T ₃End, frequency divider loses power supply and quits work, and the warning mobile phone stops to call (stopping to send warning message).

The utility model can adopt two kinds of types of service: a kind of is dual-purpose type, and the mobile phone of promptly reporting to the police automatically can be used as the use of reporting to the police, and also can be used as to make a phone call usually to use.Report to the police when using, the mobile phone of reporting to the police automatically must be awaited orders under off-mode, and alarm signal sends slow.Another kind of form is a tailored version, only uses as reporting to the police.Be characterized in and can await orders under open state that alarm signal sends very fast, a lot of functions of former mobile phone can be deleted, and favourable reduced volume cooperates but also can carry out network, as: the adapted special number makes the guarder be easy to identification; Phone to get, cannot be squeezed into only, when enabling to save network, also improves reliability.
