Problems solved by technology

[0005] However, in the above-mentioned existing wireless communication system, there is such a problem: during the operation of the transceiver circuit, any circuits that do not need to be operated such as the transceiver control device 130 are not considered, so the power consumption is not effectively reduced.
[0007] In the above-mentioned existing wireless communication system, there is a problem that in a wireless communication system composed of a plurality of circuit modules, each of the plurality of circuit modules cannot achieve low power consumption.
In addition, for the meter look-up system and the observation system, it is not necessary to run the circuit block including the radio signal sending and receiving function during the meter look-up process or when the meter is being observed.

Embodiment 1

[0021] FIG. 1 is a block diagram of a wireless communication device including an intermittent operation control circuit of the present invention.

[0022] The wireless communication device is composed of a wireless sensor network system unit 310 , an intermittent operation control circuit 360 , a power supply control circuit 370 , a battery 380 , and an antenna 390 . The wireless sensor network system unit 310 is composed of a sensor circuit unit 320 , an analog-to-digital converter (ADC) 330 , a transceiver circuit 340 , and an MPU 350 . The sensor circuit part 320 has several sensor circuits 321-32n, and these sensor circuits include various environmental observation functions for observing natural environments such as air temperature, room temperature, humidity, and sunlight. The function of the output after the electrical signal.

[0023] The ADC 330 converts the analog electrical signals output by the sensor circuits 321 to 32n including various environmental observation...

Embodiment 2

[0032] Fig. 3 is a block diagram of an intermittent operation control circuit of a second embodiment of the present invention. The intermittent operation control circuit 360 is composed of the time measuring device 210 , the time signal output devices 220 to 22n, and the crystal oscillator 240 . The time measuring device 210 can pre-arbitrarily set a time interval or elapsed time in units of any one of year, month, day, week, hour, minute, and second according to the function of the real-time clock. The time signal output devices 220 to 22n output inverted signals after a time interval or elapsed time arbitrarily set in advance by the time measuring device 210 .

Embodiment 3

[0034] 4 and 5 are block diagrams of the intermittent operation control circuit of the third embodiment of the present invention. Different from the intermittent operation control circuit shown in FIG. 2 and FIG. 3 , it includes a serial data input and output device 250 .

[0035] Since the serial data input / output device 250 is included, the time interval or elapsed time of the time measuring device 210 can be arbitrarily set from the outside by transmitting data to the serial data input / output device 250 . In addition, the serial data input / output device 250 has a function of notifying the time interval or elapsed time measured by the time measuring device 210 to the outside.

[0036] The time signal output devices 220 to 22n output inverted signals at a time interval or elapsed time arbitrarily set by the time measuring device 210 .

[0037] As described above, since the function of controlling independent arbitrary time intervals or elapsed times of a plurality of time si...

Abstract

The invention provides a wireless communication device which uses a battery as a power source and saves electricity by reducing standby power. The wireless communication device comprises a time measuring device (210) and a plurality of time-signal output devices (220-22n), and leads the necessarily minimal circuit blocks to run or leads a plurality of circuit blocks to intermittently run with power supply from necessarily minimal power sources in a necessarily minimal time in any independent time interval or any independent elapsed time.

Description

technical field [0001] The present invention relates to a wireless communication system using a battery as a power source, by having an intermittent operation control function to manage the operation time of a plurality of circuit modules, thereby realizing low power consumption and prolonging battery life, wherein the intermittent operation control function has : A means for changing the level of a signal within any independent time interval output by a plurality of time signal output devices or within any independent elapsed time. Background technique [0002] In particular, in a wireless communication system using a battery as a power source such as a portable wireless communication system, communication becomes impossible after the life of the battery expires. Therefore, in order to operate the wireless communication system for a long time all the time even when the battery is within the service life, it becomes necessary to realize the technology of realizing power cons...
