Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to uploading data collected by a data terminal device such as a handy terminal driven by a battery to a host device such as a personal computer, and downloading master data to the data terminal device from the host device. TECHNICAL FIELD The present invention relates to an information processing system that executes data transfer in the case of performing the transfer, a control method thereof, a data terminal device, and an information processing device.

[0002]

2. Description of the Related Art Conventionally, the remaining battery level of a data terminal device such as a handy terminal is always detected during operation.
When a predetermined level is reached, a warning is issued to an operator or only an application program is notified. Further, when transferring collected data to a personal computer serving as a host device, the SOCON does not consider the remaining battery level of the handy terminal at all.

[0003]

However, in a conventional system comprising a handy terminal and a personal computer, when data is transferred between the handy terminal and the personal computer, if the battery runs out during the data transfer, the data transfer is interrupted. Could be interrupted. In this case, the personal computer side is treated exactly the same as an error such as a line disconnection. In addition, the original information of the battery shortage is only displayed on the handy terminal side, and the display of the handy terminal is small, so it is difficult to grasp the cause.

The process flow described below is executed when the data transfer process is started by an operator or an application program.

First, in step S4-1, current battery remaining amount information is obtained from the handy terminal 2 through the communication port 9. In step S4-2, it is determined whether the data transfer is in the upload direction for receiving data from the handy terminal 2 or in the download direction for transmitting data to the handy terminal 2. This direction is specified by an operator or an application program when starting data transfer.

When the upload direction is set (step S
YES at 4-1), and proceeds to step S4-3. In step S4-3, the amount of data to be transferred is obtained from the handy terminal 2 side. On the other hand, in the case of the download direction (NO in step S4-2), the process corresponding to step S4-3 is unnecessary because the personal computer 1 knows the data amount. In step S4-4, an estimated time required for data transfer is calculated from the data amount. In step S4-5, the expected operation time calculated from the information on the remaining amount obtained in step S4-1 is compared with the expected transfer time calculated in step S4-4 to determine whether the remaining battery level is sufficient. I do.

If it is determined that the remaining battery power is sufficient (YES in step S4-5), the flow advances to step S4-6.

Then, the handy terminal 2 side data transfer is started.
Various protocols are known for the data transfer method,
In the first embodiment of the present invention, the protocol is not known.

In step S4-5, when it is determined that the remaining battery power is insufficient (NO in step S4-5), the process proceeds to step S4-7. In step S4-7, the portable terminal 2 is notified that data transfer is not possible. In step S4-9, an error message indicating that the remaining battery level is insufficient is displayed on the CRT 2 to call the operator's attention and the process ends.

As described above, when the data transfer cannot be completed due to a shortage of the remaining battery when the data transfer process is started, a message to that effect is sent to the CRT 6 of the personal computer 1.
Will be displayed on the screen. FIG. 5 is a flowchart showing a processing flow on the handy terminal side of the data transfer processing according to the first embodiment of the present invention.

The processing flow described below is executed when the data transfer processing is started by an operator or an application program, similarly to the personal computer 1.

And informs the personal computer 1 of the remaining amount information via the communication port 17. In step S5-2, it is determined whether the data is to be transmitted in the upload direction for transmitting data to the personal computer or to be received and downloaded from the personal computer. This direction is specified by an operator or an application program when starting data transfer.
If it is the upload direction (YE in step S5-2)
S), and proceed to step S5-3. On the other hand, if it is the download direction (NO in step S5-2), step S5
Jump to 5-4.

In step S5-3, the amount of data to be transferred is notified to the personal computer 1 via the communication port 17. In step S5-4, the personal computer 1 receives the result of determining whether communication is possible. The result is
This corresponds to step S4-6 or step S4-7 in the flowchart of FIG. In step S5-5, it is determined whether data transfer is possible based on the received result. If data transfer is possible (YES in step S5-5), the flow advances to step S5-6. Step S5-6
Then, data transfer is started. As described on the personal computer 1, the data transfer is not involved in the first embodiment of the present invention.

On the other hand, if data transfer is not possible (NO in step S5-5), the flow advances to step S5-7. In step S5-7, an error message indicating that the remaining battery power is insufficient is displayed. In the first embodiment of the present invention,
The calculation and judgment of the estimated time required for data transfer are performed on the PC side. This is because the personal computer generally uses a CPU having a higher processing capability. Of course, the gist of the present invention can be realized even if the result is sent to the handy terminal 2 and the result is notified to the personal computer.

As described above, according to the first embodiment, an error message when the remaining power of the handy terminal is insufficient is displayed on both the handy terminal 2 and the personal computer 1 so that the operator can easily read the error message. You can check. <Second Embodiment> In the first embodiment described above, the data transfer processing in the system including one personal computer and one handy terminal has been described.
