(5) embodiment

This specific embodiment comprises signal projector, signal receiver and a Personal Handyphone System, and signal receiver links to each other with the well-informed key of answering.

Signal projector comprises transmitter module and supply module, and supply module comprises the power supply V of 12V ₁, triode VT ₂, capacitor C ₁, resistance R ₁, R ₂And switch S ₁, S ₂, capacitor C ₁, resistance R ₁, switch S ₁Series circuit and power supply V ₁Parallel connection, triode VT ₁, switch S ₂, transmitter module series circuit and power supply V ₁Parallel connection, triode VT ₁Base stage connect resistance R ₂, resistance R ₂With capacitor C ₁An end link to each other triode VT ₁Emitter and capacitor C ₁The other end link to each other.

Signal receiver comprises receiver module, control module, single switch relay K ₁Power supply V with 9V ₂, receiver module passes through relay K ₁Connect power supply V ₂, control module comprises the biswitch relay K ₂, triode VT ₂, capacitor C ₂And resistance R ₃, R ₄, relay K ₂One contact is connected in relay K ₁On, triode VT ₂Collector is connected relay K ₂On, triode VT ₂Base stage is resistance in series R successively ₄, R ₃, resistance R ₃Be connected in relay K ₂On, triode VT ₂Grounded emitter, capacitor C ₂One end is connected resistance R ₃And R ₄Line on, the other end and triode VT ₂Emitter link to each other relay K ₂There are two contacts to be connected answering on the key of Personal Handyphone System.

Principle of work: at S ₁Closed S ₂In the time of separately, electric current passes through R ₁Give C ₁Charging is because of R ₁C ₁For a short time, be full of very soon, transmitter module is not worked, at S ₁Separate S ₂When closed, C ₁Pass through R ₂VT ₁Discharge, at this moment VT ₁Conducting work makes transmitter module have 12V voltage to start working, and launches control signal, 5 working times in second only, receiver module after receiving 5 second working signals, K ₁Closure, K ₂Coil is through VT ₂R ₃R ₄C ₂Charging work, K ₂Switch closure, at this moment C ₂Discharge, VT ₂Quit work K ₂Switch separates, at this moment again through VT ₂R ₃R ₄C ₂Charging makes VT ₂Work, K ₂Closure is charged and discharge work like this.Transmitter module work 5 seconds, K ₂Control Personal Handyphone System four closures and are separately finished and are pulled out logical master cellular phone and reach warning, and power supply can use 15 days.

Personal Handyphone System can replace using with mobile phone or landline telephone in this specific embodiment.
