The monitor controller 4 and the like receive the radio waves. Furthermore, control signals from the monitor controller 4 are used to control equipment 5 that operates in response to remote control. The monitor controller 4 and the plurality of devices 5 are connected through control lines 6, respectively. Furthermore, the connection form between the monitor controller 4 and the device 5 may be any bus connection, star connection, or the like. In addition, as an example of a wired remote control method, J
There are EM-A standard, Matsushita Electric Works 2-wire remote controls, etc.

Radio waves emitted from the cordless telephone handset 1 are received by the cordless telephone handset 2 and also by the monitor controller 4. FIG. 2 shows a block diagram of the monitor controller 4. A receiving section 12 receives and demodulates radio waves from a cordless telephone subunit l via an antenna 11. By the way, there are examples in which the frequency and modulation method of radio waves emitted from cordless telephones are determined by regulations.

For example, Japan's low-power cordless telephones, the US's FCC
That is the standard. Therefore, the receiving frequency and modulation method (FM) of these cordless telephones are known. However, in reality, a multi-channel system is used with multiple transmission frequencies, so in order to capture the radio waves actually used among the known frequencies, the reception frequency control unit 1
3 is used. This receiving frequency control section 13 constantly sweeps and monitors the frequency that the cordless telephone subunit 1 can transmit, and when the cordless telephone subunit 1 is transmitting, it stops at that transmission frequency and brings the receiving section 12 into the receiving state. It is something to do. That is, as shown in FIG. 3, the frequencies that can be transmitted by the cordless telephone subunit 1 are sequentially monitored (a) in the figure, and when a transmitted wave is received, the sweep is stopped at that frequency to enter the receiving state.

The PB and other signal determination 14 inputs the demodulated signal from the receiving section 12 and determines the push-button tone signal from the cordless telephone subunit 1. In the case of a push-button tone signal, the signal is sent to the signal processing section 16. send. Regarding the control signal to the device 5 that operates in response to remote control,
Information is input from the operation unit 15 so that the push-button code, which is a combination of a specific control signal and a push-button tone signal from the cordless telephone handset 1, corresponds to the push-button code. Then, the associated control contents are stored in the memory 17. Note that the push button code is normally set to an area number that is not connected even when a call is made, that is, it is set to an unused area number.
A control interface 18 is provided between the control line 6 and the control line 6 .

Next, the entire control device will be explained. First, the cordless telephone slave unit 1 is operated so that the cordless telephone slave unit 1 is connected to the telephone line 3.

The push button tone signal, which is composed of a combination of a plurality of frequencies, is determined by the PB and other signal determination 14 and is transmitted to the signal processing section 16'\. When the signal processing section 16 receives the squeeze push button code, it outputs the corresponding control signal described above from the control interface 18, and the device 5 operates according to the control signal sent through the control line 6.

As described above, with this device, it is possible to easily control the device 5 using the button on the cordless telephone subunit 1.

Next, another embodiment of the reception frequency control section 13 will be described. The modulation method of the cordless telephone is FM, but the transmission frequency is not known other than those specified by regulations. Therefore, in this embodiment, the frequency of the cordless telephone to be used is searched and registered. The operation is performed by the reception frequency control section 13, and from then on, reception is performed at this frequency. That is, as shown in FIG. 4, registration is performed when the cordless telephone subunit 1 is transmitting waves, and the monitor controller 4 sweeps the receiving frequency over a wide range and searches for the frequency where the transmitting waves are present. and register. Here, the number of frequencies that the cordless telephone subunit 1 transmits is one, and that frequency is f.
