A calling on-off detection circuit is composed of resistors R7, R8, R9 and R10, diodes D1, D2 and D3, and transistor N2. The utility model has the advantage of simple circuit structure. By using the utility model, the calling subscriber number can be displayed at the same time when a telephone rings.
Description
The utility model relates to a kind of caller ID display.
Improvement along with development of electronic technology and condition of work, the owning amount of telephone set increases day by day, call convenient, thereby the utilance of telephone set is improved, can bring all tired brains to the telephone subscriber simultaneously, also following as harassing call, threatening phone call, present most telephone sets are unavoidable.Also have some telephones for special use to be provided with calling party phone number display unit, but the circuit more complicated costs an arm and a leg, and all must number be issued the callee, have only telephone office to provide extraordinary this function of service to realize by stored-program control exchange.
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned technology, a kind of a kind of caller ID display simple in structure, suitable to be provided.
The utility model is taked following technical scheme to achieve these goals.
A kind of caller ID display, comprise that outside line, ring detection, power circuit, power-on and power-off control circuit, simulation off-hook, dislodging machine testing, telephone set, telephone switch, signal are synthetic, ring-back, voice, double-tone transceiver, CPU, liquid crystal display, button, memory frequently, it is characterized in that:
A. signal is synthetic is made up of following elements
Signal input S1 serial connection capacitor C 1, resistance R 1, signal input S2 serial connection capacitor C 2, resistance R 2, signal input S3 serial connection capacitor C 3, resistance R 3, the other end of resistance R 1, R2, R3 also connects back and the base stage of triode N1 and the end of resistance R 4, R5 and connecing, another termination power Ucc of resistance R 4, the emitter of triode N1 and connecting resistance R6 and capacitor C 4, the other end of resistance R 5, R6 and capacitor C 4 also connects back ground connection, and triode N1 collector electrode meets output S4;
B. the machine testing of seting out is made up of following elements
Input signal S6 series resistor R10, the negative electrode of the D1 of the other end of resistance R 10 and input signal S7 and diode also connects, the anode of diode D1 meets power supply+E, the end of the anode of input signal S8 and diode D2 and resistance R 8, R9 also connects, the anode series of the negative electrode of diode D2 and diode D3, the emitter of the other end of the negative electrode of diode D3 and resistance R 9 and triode N2 also connects back ground connection, the other end of resistance R 8 is connected with the base stage of triode N2, the collector electrode of triode N2 and resistance R 7 and output S5 also connect, another termination power Vcc of resistance R 7.
Owing to taked technique scheme, the utility model can show caller's telephone number simultaneously at ringing telephone stations, and the user is received calls selectively, avoided unnecessary phone to disturb, simultaneously can preserve telephone number,, prevent that phone from missing when unattended for inquiry.The utlity model has the characteristics that line construction is simple, be suitable for.
Fig. 1 is the synthetic circuit diagram of signal
Fig. 2 is picking/hanging machine detection circuit figure
Fig. 3 is a theory diagram of the present utility model
Below in conjunction with embodiment shown in the drawings the utility model is further specified.
A kind of caller ID display, comprise that outside line 1, ring detect 2, power circuit 3, power-on and power-off control circuit 4, simulation off-hook 5, dislodging machine testing 6, telephone set 7, telephone switch 8, signal are synthetic 9, ring-back 10, voice 11, double-tone transceiver 12, CPU13, liquid crystal display 14, button 15, memory 16 frequently, it is characterized in that:
A. signal is synthetic is made up of following elements
Signal input S1 serial connection capacitor C 1, resistance R 1, signal input S2 serial connection capacitor C 2, resistance R 2, signal input S2 serial connection capacitor C 3, resistance R 3, the other end of resistance R 1, R2, R3 also connects the end of back and the base stage of triode N1 and resistance R 4R5 and connects, another termination power Ucc of resistance R 4, the emitter of triode N1 and connecting resistance R6 and capacitor C 4, the other end of resistance R 5, R6 and capacitor C 4 also connects back ground connection, and triode N1 collector electrode meets output S4;
B. the machine testing of seting out is made up of following elements
