Abstract

PURPOSE:To receive the information of an opposite equipment at any proper time without remarkable increase in power consumption of a battery by making calling periodically at a proper time interval depending on the situation. CONSTITUTION:An interval timer 6 counts down an initial value being a count set to a count register 7 and supplied a signal to a CPU 1 when the set count expires. Upon the receipt of this signal, the CPU 1 makes a radio dialing to an opposite equipment regardless of the presence of the information to be received in the equipment. When the opposite equipment has information to be sent, the radio communication is connected and when the opposite equipment does not have information to be sent, the CPU 1 immediately terminate the communication. Moreover, when no radio communication is implemented, the power supply to a radio oscillation circuit 3 and a radio reception circuit 5 requiring much power is interrupted. Thus, the information of the opposite equipment is received at a proper time while suppressing remarkable power consumption of a battery.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a portable wireless device that transmits and receives information wirelessly.

[Summary of the invention]

A portable wireless device is provided with an interval timer and a count amplifier time 1 to hold an initial count value of the interval timer, and a wireless call is made when the interval timer is used as a count amplifier.

Note that the value of the count register can be rewritten, and can also be rewritten by wireless communication.

[Conventional technology]

Conventionally, this type of portable transmitting/receiving wireless device always keeps the external device in a receiving state when transmitting, and receives information from the other device, and furthermore, it emits only when it has information that it wants to oscillate. The method is to make a call and use the timing to receive information from the other party's device.

[Problem to be solved by the invention]

In this way, conventional devices of this type have problems such as needing to be constantly in a receiving state, consuming large amounts of battery power, and having problems with portability.Furthermore, they have the problem of having information that they want to oscillate on their own. There was a problem in that information from the other device could not be received except when

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a portable wireless device that can receive information from a partner device in a timely manner while suppressing battery consumption.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention includes a count value holding means for setting a wireless call interval;
The apparatus is configured to include pulse generating means for generating a timing signal for wireless calling based on the count value held in the holding means.

(Function) According to the portable wireless device of the present invention configured as described above, a call can be made every time the interval timer counts up according to the count value set in the count register, and a call can be made periodically with the other device. wireless communication is possible,
It is possible to receive information from the other party's device in a timely manner while suppressing significant battery consumption.

Furthermore, by changing the setting of the count value of the count register at any time through wireless communication or the like, it is possible to appropriately control the interval of wireless calling according to the usage situation.

〔Example〕

Hereinafter, a portable radio device according to the present invention will be explained based on the drawings.

FIG. 1 is a block diagram showing an embodiment of a portable wireless device according to the present invention. In the figure, 1 is C as a control section.
PU, 2 is a modem that modulates the transmission data created by the CPUI or demodulates the reception data, 3 is a radio oscillation circuit that multiplies the transmission data modulated by the modem 2 into a high frequency and amplifies the power, 4 is an antenna, 5 is a radio receiving circuit that detects and amplifies radio waves received by antenna 4; 6 is an interval timer that outputs a timing signal for making a radio call; 7 is a count register that sets the count value of the interval timer; 8 is an external device; 9 is a keyboard for inputting data.

Next, its operation will be explained.

When transmitting information, transmission data generated by the CPU 1 is modulated by the modem 2, multiplied at high frequency by the radio oscillation circuit 3, power amplified, and then transmitted from the antenna 4 as radio waves.

Further, when receiving information, radio waves received by the antenna 4 are detected and amplified by the radio reception circuit 5, demodulated by the modem 2, and then taken in by the CPU 1 as received data.

Here, the interval timer 6 is the count register 7.
The count value set in is counted down as an initial value, and a signal is issued to the CPU when the count value is counted up. When the CPUI detects this signal, it makes a wireless call to the other party's device, regardless of whether there is information to be transmitted to itself.

At this time, if the other device has information to be transmitted, wireless communication is continued; if the other device does not have information, communication is immediately terminated.

Further, when wireless communication is not being performed, power is not supplied to the wireless oscillation circuit 3 and the wireless receiving circuit 5, which consume large amounts of power, thereby preventing battery consumption.

Also, the count value set in the count register 7 is
It can be rewritten by input data from the interface 8 or keyboard 9 under the control of the CPUI, and can be rewritten by a program stored in the CPUI. Furthermore, it is also possible to rewrite based on the data received from the other party's device, and it is possible to set the optimum call interval according to the usage situation.

〔Effect of the invention〕

As explained above, the present invention makes it possible to receive information from the other party's device in a timely manner without significantly increasing battery power consumption by making regular calls at appropriate time intervals according to the situation. There is an effect.
