As shown in FIG. 3, the incoming call sensing circuit 10 is connected in series with the line of the wired telephone 3 using a pulse transformer 100. When an incoming call signal is generated, an alternating voltage is formed at both ends of the pulse transformer 100, and the pulse transformer 100 is disposed there. The output terminal generates an induced AC voltage and current, and passes through a center-tap commutator 101 to become a pulsed DC power, and then enters a capacitor 102 to buffer the voltage to be close to a flat DC current, and has a constant voltage drop across the Zener diode 103. And driving the transistor 104 to turn on the transistor 104. After the transistor 104 is turned on, the voltage at the output terminal of the collector terminal is immediately changed from the original high potential to the low potential, and the high-low potential transition of the output terminal voltage is transmitted to transmit a wireless control. The signal is sent to the wireless transmitting circuit 11. Wherein, when the wired telephone 3 does not have an incoming call, the voltage on the line of the wired telephone 3 is a DC voltage. At this time, the output signal of the pulse transformer 100 is as shown in the following (Table 1), indicating the output of the pulse transformer 100. There is no AC voltage signal output, so the pulse The circuit at the back end of the transformer 100 has no action.

When there is an incoming call, since the incoming call signal is alternating current, the output signal of the pulse transformer 100 is as shown in the following (Table 2), and an alternating voltage is formed at both ends of the pulse transformer 100.

When there is an incoming call, the output signal of the pulse transformer 100 is rectified into a pulsed DC signal by the center tap commutator 101, as shown in the following (Table 3):

Further, as shown in the following (Table 4), the terminal voltage signal of the Zener diode 103 is buffered by the pulse DC matching capacitor 102, and the Zener diode 103 is regulated, and the signal is connected to the transistor. The 104-base extreme acts as a control for the conduction and non-conduction of the transistor 104.

As shown in the following (Table 5), the signal of the extreme voltage of the transistor 104 is shown by the signal waveform in the table. When the ringing signal comes in from the pulse transformer terminal, the signal of the collector terminal of the transistor is immediately From high potential to low potential, this signal is sent to the wireless hair circuit 11 as a remote remote control signal.

As shown in FIG. 4, the detailed circuit of the wireless transmitting circuit 11 is composed of an HT-12E encoder 110 and an RF315MHZ transmitting module 111. The collector output terminal signal of the foregoing transistor is transmitted by the RF315MHZ in the figure. The "IN" end of the left side of the module 111 enters.
