DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic dial telephone for automatically transmitting a message previously input to a memory.

[0002]

2. Description of the Related Art As a conventional automatic dial telephone, there has been proposed a telephone which transmits a previously recorded message to the other party at a designated time as disclosed in Japanese Utility Model Laid-Open No. 3-120155. Also, JP-A-3-23555
As described in Japanese Patent Laid-Open No. 8 (Kokai) No. 8, a telephone which retransmits a message at a predetermined time interval when a message is transmitted to a destination has also been proposed.

[0003]

However, in the case of the technique described in Japanese Utility Model Laid-Open Publication No. 3-120155, there is a problem that a message cannot be transmitted to a destination when there is not enough power supply capacity to transmit at a designated time. . Also,
In the case of the technology described in Japanese Patent Application Laid-Open No. 3-235558, which automatically sends a message every predetermined time, even if this technology is applied to a mobile phone whose radio wave state changes, it is not possible to send a message reliably.

SUMMARY OF THE INVENTION An object of the present invention has been made in view of such a problem. In an automatic dial telephone for automatically transmitting a message previously input to a memory, the battery power supply voltage of the telephone is measured and the power supply voltage is reduced. The present invention provides a telephone which estimates a transmission impossible time due to a message and transmits a message set to be transmitted after the time to a destination before a transmission impossible time is reached, thereby preventing omission of message transmission. .

[0005]

In order to achieve the above object, the present invention provides a method for automatically dialing a specified destination at a specified time and receiving a call by the dial transmission. In an automatic dial telephone for transmitting a message stored in advance, a timer means, a storage means for recording a destination telephone number and a transmission message, a power supply, a voltage detection means for detecting a power supply voltage, a radio wave state detection means, Setting means for setting the transmission time of a message, a function key for setting a mode for automatically transmitting the stored message at the transmission time, and capable of transmitting a message determined based on a power supply voltage detected by the voltage detection means The remaining time is compared with the transmission time required for transmitting the stored message, and the time compared is compared with the current time. The message transmission disable time is set as the last timing of the message transmission time when the elapsed time has elapsed, while the number of retransmissions and the retransmission time when the message transmission fails when the set transmission time is before the message transmission disable time. An automatic dial telephone comprising control means for determining an interval based on the radio wave state detected by the radio wave state detecting means is constituted.

[0006]

Since the present invention is configured as described above, the operations for transmitting a message include the number of retransmissions and the retransmission time interval in the radio wave state, and the message transmission disable time as the last timing of the message transmission in the power supply voltage. Decide and send the message to the other party more reliably.

[0007]

Next, embodiments of the present invention will be described with reference to the drawings. 1 to 3 are diagrams showing an embodiment of the present invention. FIG. 1 is a block diagram of a telephone according to the present invention, FIG. 2 is a flowchart of automatic message transmission, and FIG. 3 is a flowchart of message retransmission.

In the block diagram of FIG. 1, 1 is time measuring means for measuring time, 2 is storage means for recording the telephone number of the other party and a transmission message, 3 is a power supply, and 4 is a voltage detector for detecting the power supply voltage of the power supply 3. Means 5 is a function key, 6 is a remaining transmission time calculated from the power supply voltage of the power supply 3 detected by the voltage detection means 4, and is compared with the message transmission time stored in the storage means 2 for message transmission time. A control unit for performing processing such as calculating the timing of
Reference numeral 8 denotes a radio wave state detecting means.

The automatic message sending operation will be described with reference to FIG.

First, in order to automatically send a message,
The user enters the message transmission mode by operating the function key 5 or the like.
Next, in step 1, the telephone number of the destination to which the message is to be transmitted is input by the function key 5. At this time, a telephone number registered in advance for speed dialing may be used. After inputting the telephone number of the destination to be transmitted, the content of the message to be transmitted is input by voice to the storage means 2 such as a tape recorder. The content of the stored message may be a character symbol input in advance. After inputting the telephone number and the message, in step 2, the time at which the message is to be transmitted is set. After setting the above, the mode returns to the normal mode.

Thereafter, the voltage detector 4 periodically (step 4 checks the time interval set in step 3 for the timer) and proceeds to step 5 to detect the power supply voltage of the power supply 3 and the radio wave condition in step 6 to detect this. Based on the result, the controller 6 calculates the remaining time that can be transmitted at the voltage of the power supply 3 in step 7.

The total time of the message previously set by the control unit 6 is compared with the time calculated by the power supply voltage, and the time when transmission is impossible at the power supply 3 is calculated by subtracting the total time of the message from the remaining time (= (Time difference) is added to the current time to calculate. In step 8, the time value by the timekeeping means 1 is compared with the transmission disabled time. If the time is calculated, the telephone number of the other party is dialed and the message set in the message storage means 2 is transmitted in ascending order of the set time. Start.

On the other hand, until the transmission impossible time, it is checked in step 9 whether the transmission time is the previously input transmission time, and if it is the transmission time, the message is transmitted. At the time of transmission, the radio wave condition may be poor. Therefore, the control unit 6 checks the number of retransmissions and the retransmission time interval of the message determined in step 7 based on the radio wave condition previously measured by the radio wave condition detecting means 8, and a response from the other party is returned. If not, the message is transmitted up to the determined number of times.

In this retransmission method, when the radio wave condition is good, there is a high possibility of connection to the destination, so that it is not necessary to perform retransmission frequently, so that the number of retransmissions is reduced and the retransmission time interval is extended. The setting is made on the telephone 7 as described above, and when the radio wave condition is poor, the possibility of connection to the other party is low, so that the setting is automatically made to increase the number of retransmissions and shorten the retransmission time interval. If the message transmission fails, the retransmission time judgment is added to the message transmission time judgment in FIG.

FIG. 3 compares the elapsed time from the previous transmission failure with the previously set retransmission time interval in the retransmission time determination,
If the values match, a message retransmission flow chart for performing message retransmission is shown.

The control unit 6 measures the time by the timing means 1 (step 1).
0) If the retransmission time interval has elapsed since the previous failure (step 10), the previously failed message is retransmitted again in step 12, and if successful, the fact is recorded (step 14). . If it fails, the failure time and the number of failures are recorded in step 15 and the retransmission counter is decreased by 1 (step 17). At this time, if the number of retransmissions has been completed, a message transmission failure is recorded (step 18),
End resending of message. If the number of retransmissions has not been completed, retransmission is performed again in the manner described above. Since the transmission result of the message is stored in this way, it is possible to confirm whether the message has been successfully transmitted to the destination.

As described above, according to the present invention, as an operation of transmitting a message at a set time, the radio wave state and the power supply voltage are measured at a predetermined time interval, and the number of retransmissions and the retransmission time interval are measured in the radio wave state. Further, the present invention provides a telephone which determines a message transmission disable time by a power supply voltage and more reliably transmits a message to a destination. Since transmission is performed while investigating the radio wave condition, when the radio wave condition is poor, the retransmission interval is set earlier and the message is easily transmitted to the other party. Since the number of retransmissions and the retransmission time interval are set according to the radio wave condition, the message transmission can be transmitted to the other party more reliably. Even if the user himself is not near the telephone, the message can be automatically sent to the other party, so that the trouble of delaying the schedule can be eliminated.

[0018]

As described above, according to the present invention, omission of message transmission due to a decrease in power supply voltage is eliminated.
Moreover, if the message transmission fails at the transmission time set by the user, the message is retransmitted at the retransmission count and time interval according to the radio wave condition, so that the reliability is high.
