っていた。BACKGROUND OF THE INVENTION Wireless communication devices are often operated by battery power, and therefore reducing power consumption is an important issue to extend battery life. Especially the receiving part,
Since we do not know when communication will arrive, we cannot supply power only when needed. Therefore, as shown in FIG. 3, when waiting for reception, a predetermined time interval Tl,
Power was supplied intermittently at T2, and when a signal was detected, power was supplied continuously until the end of reception, thereby saving power.

The power supply control section is turned on by a part of the sensor.
The /OFF signal is used to change the power supply rate of the power supply that is intermittently supplied to the receiver during reception standby by changing the power supply time and the power supply stop time. This makes it possible to reduce the power consumption of the receiving section during reception standby as necessary.

An antenna 3.3' is connected to the receiving section 1 and the transmitting section 2, respectively. The transmission signal from the communication control section 4 is sent to the transmission section 2.
The signal is modulated by the antenna 3 and sent as a transmission radio wave to another station.

るためである。A received radio wave inputted from the antenna 3' is demodulated by the receiving section 1 and inputted to the communication control section 4 as a received signal. The power control unit 5 controls power supply to the receiving unit 1 and the transmitting unit 2. Power is supplied to the transmitter 2 only while outputting a transmit signal according to instructions from the communication controller 4. Power is supplied to the receiving unit 1 intermittently in the order of power supply and power supply stop during reception standby, and once a signal is received, power is continuously supplied until the signal ends. The sensor part 6 is a fat transistor or a Cd
A detection means for detecting a human body such as a sensor for detecting brightness such as s or an ultrasonic sensor, a setting means for setting a threshold value, and a sensor input value and a threshold value are compared and ON/Off is performed.
It consists of comparison and determination means that outputs the F signal to the power supply control section 5. The power supply control unit 5 is ON10F from the sensor unit.
The F signal changes the power supply time and power supply stop time to times with different power supply rates. FIG. 2 is a time chart showing switching of power supply time. When power is being supplied intermittently during power supply stop time T1 and power supply time T2, the signal from sensor unit 6 is ON.
When the power supply is switched from OFF to OFF, the power supply stop time T3 changes to the power supply time T2. At this time, information that the power supply stop time and power supply time have changed is transmitted to other stations. This is because a signal received from another station is always divided into a synchronization signal part and a data part, and a synchronization signal longer than the power supply stop time is added before the data part.

It can be performed. Therefore, the power supply control unit automatically changes the power supply rate in each case, and power saving during reception standby can be achieved.
