Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a method for quickly transmitting transmission data stored in a communication device having a function of storing transmission data, such as a facsimile. The present invention relates to a data transmission method for a communication device.

(Prior Art) A conventional data transmission method of a communication device equipped with a memory (hard disk drive) for storing the above-mentioned transmission data stores transmission data read by a scanner, etc., in a predetermined record number of the hard disk drive. do. The transmission data stored in the hard disk drive and waiting for transmission is transmitted via the public line to the communication device indicated by the dial number to which the transmission data is to be transmitted. Even if multiple pieces of transmission data for the same destination are stored in the hard disk drive, the data transmission method of conventional communication devices is such that the transmission data stored in the first record number of the hard disk drive is transmitted to the communication device pointed to by the dial number. Because it is transmitted via a line, it was not easy to improve transmission efficiency.

(Problem [1] to be solved by the invention) Therefore, in the data transmission method of the conventional communication device, even if multiple pieces of transmission data with the same destination are stored in the hard disk drive, they are stored in the first record number of the hard disk drive. Since the data to be sent is sequentially transmitted using separate calls, it is difficult to quickly transmit data that is waiting to be sent. Furthermore, since the amount of traffic on the public line increases, there is a risk that the transmission efficiency of transmission data will be reduced, leading to a decrease in the reliability of the device.

The present invention has been made in view of the above, and its purpose is to quickly transmit transmission data and reduce line traffic by transmitting transmission data stored in memory and destined for the same destination at once. It is an object of the present invention to provide a data transmission method for a communication device that reduces the amount of transmitted data, improves the transmission efficiency of the transmission data, and improves the reliability of the device.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a data transmission method for a communication device including a memory for storing a plurality of pieces of transmission data, including the following: a search means for searching for transmission data having the same destination among a plurality of transmission data; and a control means for transmitting the transmission data having the same transmission destination searched by the search means. This is the summary.

(Operation) In the data transmission method of the communication device with the above configuration, among the plurality of transmission data stored in the memory that stores the plurality of transmission data, transmission data having the same destination is searched for. do. Since the same transmission data for the searched destination is transmitted in one call, the transmission data can be transmitted quickly.

(Example) Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a block diagram showing control of an embodiment of a data transmission method of a communication device according to the present invention.

Applied to the above communication device, for example, a facsimile, the data transmission method of the communication device includes a data transmission method, a CPU that controls the entire device, a program that executes the operations of the CPU, and a transmission subroutine that transmits transmission data, which will be described later. It also includes a local memory 3 for storing information. Furthermore, the data transmission method of the transmitting device includes an external device interface 5, which is an interface for transmitting and receiving commands or data between the present device and an external device, such as a host device or a scanner. Further, the data transmission method includes an external device interface 5, a local bus 7 for executing data transmission between a CPU, etc., and a bird disk controller 9, which will be described later, controlled by the CPU.

The hard disk controller (hereinafter referred to as controller) 9 controls storage and retrieval of transmission data in a hard disk drive 11, which will be described later, based on instructions from the CPU.

Here, the hard disk drive (hereinafter referred to as hard disk) 11 will be explained using FIG. 2. The hard disk 11 stores transmission data transmitted via the external device interface 5 and read by an external device, such as a scanner, in the order of record number (i). The transmission data includes a dial number destination (D(i)) to which the transmission data is to be transmitted, and a flag (F(i)) indicating the presence or absence of data waiting to be transmitted. When F(i)-1, it indicates that the data is waiting to be sent. The above transmission data is
Among the data from record number “0” to record number “7”, the record number rOJ and record number “6”
"'s destination is r2722J, and the record number "
1" and the destination of record number "3" is r2727J.

The transmission subroutine started by the above CPUI call searches for transmission data of the same destination record number "0" and record number "6" and sends it to the destination r2722J.
Dial in to the dial number. As a result of dial-in, when it is possible to talk to the destination "2727", the sending subroutine sends the record number "0" of the destination r2722J.
Same destination as [AAAAAAJ of r2722. The transmission data of rzzzJ with the record number "6" of J is transmitted.

Similarly, rB B B BJ with record number "1" and rDDDJ with record number "3" of destination r2727J
Send. On the other hand, when the result of dial-in is that communication with the destination is not possible, the CPUI executes error processing (abnormal termination processing) to display a message indicating that communication is not possible on a CRT (not shown) to notify an error.

Note that the record number "4" and the record number are in a state where no data to be sent is stored due to the flag "0".

Returning to FIG. 1, the communication procedure control unit 13 controls communication procedures with a public line 17, which will be described later, and the modem 15 transmits or detects communication signals via the public line 17. The public line 17 transmits transmission data read by the facsimile, which is the communication device of this embodiment, to another communication device indicated by the destination.

Next, the operation of this embodiment will be explained using the flowchart of FIG.

First, after powering on the device, the system starts up and the CPU
calls a transmission subroutine stored at a predetermined address in the local memory 3.

The CPUI sets a record number to be transmitted among the transmission data stored in the hard disk 11, for example "0", and starts the transmission subroutine (steps 1-00 to 12o).

The above transmission subroutine is F (i)-1, and searches the hard disk 11 for transmission data having the same destination as the destination "2722" of the set record number rOJ. The search results in record number "0" and record number "6".
” and the destination r2722J are the same, the sending subroutine dials in to the dial number r2722J (
Steps 130-140).

As a result of dial-in, if a call is possible, the transmission subroutine transmits the transmission data rAAAAAAJ of the record number "0" of the destination r2722J and the transmission data rzzzJ of the code number "6" of the destination r2722J to the destination indicated by the destination via the public line 17. Send to communication device. On the other hand, if the call is not possible as a result of dial-in, the sending subroutine performs abnormal termination processing, for example, displays a message such as "Unable to communicate" on the CRT (not shown), then returns to the called program. address (steps 150-180).

Furthermore, when transmitting data for destination r2727J, record number "1" is set, a transmission subroutine is called, and transmission data having the same record number "3" as the destination "2727" is searched. The subroutine sends r2727J, which is the destination of the searched sending data, as follows:
Record number "1" when dialing in and communication possible
rB B B BJ and rD of record number "3"
DD” to destination r2727J.

By the above operation, the record number to be transmitted is set and the transmission data stored in the hard disk 11 is transmitted.

Thereby, the transmission data can be transmitted more quickly than in the conventional method of transmitting the transmission data stored in the first record number.

Of course, this embodiment can be applied to a storage/exchange machine in addition to a facsimile.

[Effects of the Invention] As explained above, according to the present invention, by transmitting the transmission data stored in the memory to the same destination at once, the transmission data can be quickly transmitted, and the amount of traffic on the line can be reduced. , and improve the transmission efficiency of transmitted data.
It is possible to improve the reliability of the device.
