Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable data transmission device driven by a battery and having a file data transmission function.

[0002]

2. Description of the Related Art In general, a device in which a battery-powered mobile phone and a file data storage device are integrated will be described with reference to FIG.

A voice signal a input from the voice input circuit 91
Is input to the transmission signal processing circuit 92. The audio signal b output from the signal processing circuit 92 is input to the telephone line connection circuit 93. The telephone line connection circuit 93 exchanges voice signals with the other party through the telephone line Tel. The voice signal c of the communication partner received by the telephone line connection circuit 93 is input to the reception signal processing circuit 94. The output audio signal d of the reception signal processing circuit 94 is input to the audio output circuit 95.

The data file read circuit 96 reads the recorded file data from the memory 97,
Input to the data transmission processing circuit 98. The output signal e of the data transmission processing circuit 98 is input to the telephone line connection circuit 93.

The power supply circuit 99 supplies power from the battery 100 to each circuit. Battery level detection circuit 1
01 detects the remaining amount of the battery 100 and supplies the result to the comparison circuit 102. The comparison circuit 102 compares the reference voltage Vref and controls the power supply circuit 99 and the warning sound generation circuit 103 based on the comparison result. The warning signal f generated by the warning sound generation circuit 103 is input to the voice output circuit 95. The audio output circuit 95 drives the speaker SP.

The operation of the circuit thus configured will be described. With respect to the voice signal a of the user input from the voice input circuit 91, the transmission signal processing circuit 92 performs the processing necessary for transmitting it through the telephone line Tel. The processed output voice signal b is transmitted from the telephone line connection circuit 93 to the other party via the telephone line Tel.

On the contrary, the voice signal c received by the telephone line connection circuit 93 via the telephone line Tel and processed by the other party for transmission is transmitted to the received signal processing circuit 94, and the voice signal c is transmitted. Is processed so that it can be output as. The voice signal d of the other party can hear the other party's message by the voice output circuit 95 driving the speaker SP.

When transmitting a data file, the file to be read is designated from the data file reading circuit 96 to the memory 97, and the file data is read. The read file data is input to the data transmission processing circuit 98 and subjected to processing necessary for transmission via the telephone line Tel. The processed data signal e is transmitted to the other party through the telephone line connection circuit 93 and the telephone line Tel.

The remaining amount of the battery is detected by comparing the detection result X detected by the remaining battery amount detecting circuit 101 with the comparison circuit 1
02 and compares it with the reference voltage Vref. When reference remaining amount 1 <X <reference remaining amount 2, warning sound generating circuit 1
A warning signal f is output from 03 to the audio output circuit 95, and the speaker SP informs the user that the battery will be exhausted. When X <reference remaining amount 1 <reference remaining amount 2, the telephone line connection circuit 93 disconnects the line connection,
The power supply from the power supply circuit 99 to each circuit is stopped.

As described above, since the user is informed in advance of the decrease in the remaining battery level, in a normal conversation, there is no problem if the conversation is ended as soon as possible.

However, when data is being transmitted, the battery can be held until the end of the data transmission. However, if the battery runs out during the transmission, the connection with the telephone line is automatically cut off, and the transmitted data contents are lost. In the worst case, the transmitted data may be completely wasted. In this case, there is a problem that the line usage fee and time required for data transmission are wasted.

[0012]

In the above system, there is a possibility that the battery may run out during file data transmission and the file may not be transmitted to the end, resulting in waste of time and communication cost required for transmission. There was a problem that became.

The present invention is a portable data transmission which does not waste communication cost because data transmission is performed when the remaining battery level is low and the battery runs out during transmission. Provide a device.

[0014]

In order to solve the above-mentioned problems, in the portable data transmission apparatus of the present invention, the file capacity to be transmitted and the remaining battery level of the equipment necessary for transmitting the file are confirmed in advance. If the remaining battery level is not sufficient to transmit the file to be transmitted, the user is warned.

Thus, when the file data is to be transmitted, it is checked whether the battery has the battery until the transmission file data is completely transmitted. If the battery has the battery, the file transmission is performed. Since a message is output, there is no need to worry about running out of battery during transmission.

Further, the file capacity to be transmitted and the battery remaining amount of the device required to transmit the file are confirmed in advance. If the battery remaining amount is not sufficient to transmit the file to be transmitted, the user is informed. It is characterized by being provided with a selection function capable of issuing a warning and selecting whether or not to transmit.

As a result, when the file data is to be transmitted, it is checked whether or not the battery has the battery until the transmission file data is completely transmitted, and if the battery has the file, the file transmission is performed. It can be displayed and let the user decide whether to perform the transmission.

When sending a plurality of files,
Each time one file to be transmitted is transmitted, the capacity of the file to be transmitted and the remaining battery level of the equipment required to transmit the file are confirmed in advance, and the file required to be transmitted next is required. When there is no remaining battery power, a message is sent out, and a stop function for stopping the transmission of the file to be transmitted is provided.

By this means, when a plurality of file data are to be transmitted, each time a file is transmitted, it is checked whether or not the battery has the transmission file data until it is completely transmitted. If not, the battery replacement message is output and the start of the next file transmission is stopped, so there is no concern of running out of battery during data file transmission.

When transmitting a plurality of files,
Every time one file to be transmitted is transmitted, the capacity of the file to be transmitted and the remaining battery level of the device required to transmit the file are confirmed in advance, and the file required to be transmitted next is required. When the battery level is low, a message is output, the transmission of the file to be transmitted is stopped, and the information of the file name of the already transmitted file and the untransmitted file name is left. It is characterized by By this means, if you try to transmit multiple file data and the battery runs out before transmitting all the selected files, file transmission is stopped and the untransmitted file name is recorded as information. There is no concern that the battery will run out during transmission, and the name of the untransmitted data file can be found later, so you can retransmit after replacing the battery.

Furthermore, when selecting a file to be transmitted from a plurality of files, the total capacity of the file to be transmitted and the battery remaining amount of the equipment required to transmit the file are confirmed, and the confirmed battery remaining amount is confirmed. Therefore, when the file to be transmitted exceeds the transmittable capacity, a warning is issued or a warning is issued and the file cannot be selected.

By this means, when a file is selected to transmit a plurality of file data, it is checked whether or not the battery has the battery until all the selected files have been transmitted. If the battery does not have the battery, finally, By deselecting the selected file name, the user can select only the files that can be transmitted with the current battery level. As a result, the selected file can be surely transmitted without running out of battery on the way.

Furthermore, if the remaining battery level of the device required for the file to be transmitted is confirmed in advance and it is determined that there is not enough battery level to transmit to the end during the transmission of the file to be transmitted, the file division processing is performed. Then, the transmission of one of the divided files is terminated, the information indicating the division is left, and the untransmitted file of the divided file is transmitted after the battery is replaced or the battery is charged. It is characterized by

By this means, while transmitting file data, it is checked whether or not the battery data can be transmitted to the end and whether or not there is a battery remaining amount. Since the file data is divided and the data transmission is completed halfway and the division information is saved, it is possible to avoid wasting the file data transmitted up to that point due to the battery exhaustion.

First, the microcomputer 11 asks the user to select a data file to be transmitted. In order to check the capacity of the selected file, the microcomputer 11 outputs the control signal a to the data file storage unit 12. The data file storage unit 12 outputs the capacity data of the selected file to be transmitted to the microcomputer 11 as file data c. The microcomputer 11 calculates the time required to complete the file transmission from the file capacity data and the file transmission speed in the data transmission processing unit 13. The battery remaining amount detector 14 detects the battery remaining amount of the battery 15 and outputs the detection information f to the microcomputer 11. The microcomputer 11 determines whether the battery 15 has the file transmission required time calculated by the remaining amount of the battery remaining amount detector 14.

An instruction to read the file data is output to the data file storage unit 12. The file data c read from the data file storage unit 12 is output to the data transmission processing unit 13 as transmission data.

On the contrary, when it is determined that the file transmission is not completed, the microcomputer 11 causes the message output unit 16 to
A message signal g having the content such as "Because the remaining battery power is low, please replace and charge the battery before transmission" is output.

In this embodiment, when the file data is to be transmitted, it is checked whether or not the battery has the capacity until the transmission of the transmission file data is completed, and if the battery has the file, the file transmission is performed. If you do not have it, a message to replace the battery is output, so you do not have to worry about running out of battery during transmission.

Next, a second embodiment of the present invention will be described with reference to the flow charts of FIGS. 1 and 3. The process up to the determination of "whether the battery during transmission is held" in the flowchart of this embodiment is the same as the determination in the flowchart of FIG. In addition, in the judgment by the microcomputer, the probability of the remaining battery capacity from the required transmission time and the remaining battery capacity to the end of the transmission is calculated. For example, 50% when it is difficult to have it and 5% when it is unlikely to have it.

When it is determined that the battery is surely held until the end of the file transmission, the transmission of the file data is started as in the first embodiment.

When it is determined that the file transmission is not completed, the microcomputer 11 indicates to the message output unit 16 that "the battery level is low, so the battery may run out during the transmission. The battery may run out during the transmission. Is a **%. A message signal g with the content such as "Are you sure you want to start transmission?" Is output, and it is up to the user to decide whether or not to carry out the transmission. When the user selects to start the transmission, the microcomputer 11 instructs the data transmission processing unit 13 to start the transmission by the control signal e, and outputs the file data reading instruction to the data file storage unit 12. The file data c read from the data file storage unit 12 is output to the data transmission processing unit 13 as transmission data d. On the contrary, when the transmission is not selected, the process ends.

As described above, in this embodiment, when the file data is to be transmitted, whether or not the battery has the battery is checked until the transmission file data is completely transmitted, and when the battery has the file, the file transmission is performed.
If not, the probability can be displayed and the user can decide whether to perform the transmission.

A third embodiment of the present invention will be described with reference to the flowcharts of FIGS. 1 and 4.

First, the microcomputer 11 selects all data files to be transmitted from the user. The microcomputer 11 outputs the control signal a to the data file storage unit 12 in order to check the capacity of the file which starts transmission first. The data file storage unit 12 outputs the capacity data of the selected file to be transmitted to the microcomputer unit 11 as file data c. The microcomputer 11 calculates the time required to transmit and finish the file based on the file capacity data and the file transmission speed in the data transmission processing unit 13. The battery remaining amount detection unit 14 includes a battery 15
Of the battery remaining amount of
Is output. The microcomputer 11 determines whether the battery 15 has the file transmission required time calculated by the remaining amount of the battery remaining amount information f.

When it is determined that the battery 15 has the battery until the end of file transmission, the microcomputer 11 determines the data transmission processing unit 1
An instruction to start transmission is given to the control signal e at 3, and an instruction to read file data is output to the data file storage unit 12. The file data c read from the data file storage unit 12 is output to the data transmission processing unit 13 as transmission data d.

After the first data file transmission is completed, similarly, the capacity of the file to be transmitted next is checked, the remaining capacity of the battery 15 is checked, and if it is determined that the battery 15 has the file transmission, the file transmission is started. The above cycle is repeated until all the selected files are transmitted.

On the way, when it is determined that the battery does not have until the end of the file transmission, the microcomputer 11 indicates to the message output unit 16 that "the remaining battery level is low, the selected file is ***, +++, ○○○. The message signal g with a message such as "Please replace the battery and charge before transmitting" is output.

As described above, when a plurality of file data are to be transmitted, it is checked every time each file is transmitted whether or not the battery has the transmission file data, and if the battery has the file transmission, the file transmission is performed. If not, the battery replacement message is output and the start of the next file transmission is stopped, so there is no concern of running out of battery during data file transmission.

A fourth embodiment of the present invention will be described with reference to the flowcharts of FIGS. 1 and 5. The flowchart of FIG. 5 of this embodiment is the same as the processing of “display the file name not transmitted” of the flowchart of FIG. 4, and the subsequent processing will be described here.

The microcomputer 11 outputs the file name not transmitted to the message output unit 16. Next, the file name not transmitted is output so as to be recorded in the data file storage unit 12 as the control signal b. After replacing the battery, the remaining data files are transmitted based on the control signal recorded in the data file storage unit 12.

In this embodiment, when there is a possibility that the battery runs out before transmitting all the selected files when transmitting a plurality of file data, the file transmission is stopped and the untransmitted file name is used as information. Since the data is recorded, there is no concern that the battery will run out during data transmission, and the name of the untransmitted data file can be identified later, so it can be transmitted again after the battery is replaced.

Next, a fifth embodiment of the present invention will be described with reference to the flow charts of FIGS. 1 and 6.

First, the battery remaining amount detecting portion 14 detects the battery remaining amount of the battery 15 and outputs the remaining amount information f to the microcomputer 11. The microcomputer 11 calculates the maximum file capacity that can be transmitted from the remaining amount information f of the battery 15 and the file transmission speed in the data transmission processing unit 13. A user selects a data file to be transmitted from the microcomputer 11 and adds the selected file name to the transmission file list.

Next, the microcomputer 11 outputs the control signal a to the data file storage section 12 in order to check the capacity of the total file of the created transmission file list. In the data file storage unit 12, the microcomputer 1 uses the full capacity data of the selected file to be transmitted as the file data c.
Output to 1. The microcomputer 11 compares the calculated maximum file capacity that can be transmitted with the file data c that represents the total capacity data of the file to be transmitted, and if the maximum file capacity that can be transmitted is larger, the battery during transmission has the The user selects the next data file to be transmitted, and the above contents are repeated until the file selection is completed.

When the total capacity of the file to be transmitted is larger, it is determined that the battery is not held until all the selected file data is transmitted, and the microcomputer 11 displays the message "The battery is low. , The selected file cannot be transmitted. "Is output, and the message signal g is output. Then, the last selected file name is deleted from the transmission file list.

After the file selection is completed, the microcomputer 11 instructs the data transmission processing unit 13 to start the transmission by the control signal e, and sequentially outputs the file data reading instruction to the data file storage unit 12 according to the transmission file list. To do. The file data c read from the data file storage unit 12 is output to the data transmission processing unit 13 as transmission data d.

As described above, when a file is selected for transmitting a plurality of file data, it is checked whether or not the battery has the battery until all the selected files have been transmitted. By deselecting the selected file name, the user can select only the files that can be transmitted with the current battery level. As a result, the selected file can be surely transmitted without running out of battery on the way.

Next, a sixth embodiment of the present invention will be described with reference to the flow charts of FIGS. 1 and 7.

The data file to be transmitted from the user is selected by the microcomputer 11. The microcomputer 11 issues a transmission start instruction to the data transmission processing unit 13 using the control signal e, and outputs a file data read instruction to the data file storage unit 12. The file data c read from the data file storage unit 12 is output to the data transmission processing unit 13 as transmission data d.

The battery remaining amount detecting portion 14 detects the battery remaining amount of the battery 15 and outputs it to the microcomputer 11 as remaining amount information f. The microcomputer 11 calculates the maximum file capacity that can be transmitted from the battery remaining amount information f and the file transmission speed in the data transmission processing unit 13.

The microcomputer 11 checks the untransmitted capacity of the file being transmitted, and compares the calculated maximum file capacity with the untransmitted capacity. As a result of the comparison, when the maximum file capacity is larger, it is determined that the battery has the battery during the file transmission, and the transmission is continued.

On the contrary, when the untransmitted file capacity is larger, it is judged that the file data being transmitted cannot be transmitted to the end, and the untransmitted data portion is divided into files, and the file transmission is terminated at the divided portions. To do so. Next, the microcomputer 11 records this division information in the non-volatile memory 121 of the data file storage unit 12.

As described above, during transmission of file data, it is checked whether or not there is a battery remaining capacity to determine whether or not the file data can be transmitted to the end. Since the file data is divided and the data transmission is completed halfway and the division information is saved, the file data transmitted until then can be prevented from being wasted due to the battery exhaustion.

Further, a seventh embodiment of the present invention will be described with reference to the flow charts of FIGS. 1 and 8.

Immediately after the power is turned on, the microcomputer 11 searches the data file storage unit 12 to see if the division information is recorded. As a result, when the division information is recorded, the message output means 21 is asked to ask the user whether to transmit the remaining divided file data.
1 outputs a message signal g having a content such as "There is a divided file. Would you like to transmit?". When the user selects transmission, the microcomputer 11 reads the division information from the data file storage unit 12, specifies a file to be transmitted according to the information, and transmits the divided data. After the data transmission is completed, the information necessary for returning the divided data file to the original one is transmitted to the other side, and finally the division information recorded in the data file storage unit 12 is deleted.

In this embodiment, the remaining divided data can be automatically transmitted, and the division information recorded in the data file storage unit 12 can be deleted.

As described above, according to the present invention, when the file is transmitted, the remaining battery level is checked in advance, so that the battery runs out during the transmission of the file data, and the data and the transmission that have been transmitted up to that time are transmitted. There is no need to waste time and line usage charges.

[0062]

As described above, according to the present invention,
When performing file transmission, the remaining battery power is checked, and transmission is performed if it is determined that there is enough battery to transmit the data file capacity, preventing data transmission failure due to battery exhaustion during data transmission. it can.
