Abstract

PURPOSE:To facilitate the discrimination for the end of reception of data, by providing a display function for the time needed for communication of the transmitter side to the receiver side. CONSTITUTION:The data transmitted from the remote station through a circuit NET is received at a communication control part 7 on the basis of a prescribed receiving procedure. The received data is decoded by a data processing part 8 for reproduction of the data and then sent to a data recording part 9 to be recorded there. At the same time, the information on the time needed for communication which is transmitted from the remote station and received at the part 7 is stored at a communication time storing part 10. Based on the contents of storage, the desired communication time of the remote station is displayed at a communication time display part 11.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data communication system in which the injured device side has a function of displaying communication time on the transmitter side.

Conventionally, data transmission and receiver N, such as facsimile,
In a data communication system with B't' data transmission *V, if the wAK local station attempting to perform data transmission is in the process of receiving data transmission.

In the case of a system in which receiving and receiving data cannot be performed at the same time, the operator has to be on standby even though it is not known when the other party's data transmission will be finished, resulting in wasted time. There is a problem with putting it away.

The present invention has been made to solve these problems, and by adding a receiver to the receiver to calculate the time required for communication at the other station, the operator can easily calculate the length of the receipt from the own station.
The present invention provides a data communication system that allows users to easily determine when the data is released.

Hereinafter, one MjA example of the present invention will be described with reference to the knitting drawings.

In the data communication system according to the present invention, as shown in FIG. Processing for transmission such as encoding by the sound data processing unit 3
The processed data was subjected to a single transmission procedure using the overconfidence control i14.
a data transmission system that transmits data to the other station via the
A communication time calculation unit 5 reads the amount of data stored in the data storage unit 2, the data transmission speed in the communication control unit 4, t, calculates the required communication time 9, and gives the result to the communication control unit 4, and calculates the amount of time. The required communication time [to be displayed communication time display s6].

Also, on the receiver side, as shown in Figure 2,
The communication controller 7 receives data transmitted from the partner station through the NET Y, and the received data is processed by the data processor 1ls8 for data reproduction such as decoding. The data receiving system sends the information to the data recording unit 9 for distribution, and the communication control unit 7 receives the #i friend communication time information sent from the other station and sends it to the data recording unit 9 for distribution. 10 and the other station's communication Ifr! according to its memory contents. 'The overconfidence time display section 11 displays the time.

The operation of the inventive data exchange system configured as described above will be explained below.

First, in the transmitter 11, the data control unit 1 reads 4! In addition, when storing data in the data storage unit 2, the data is processed equivalent to the data processing unit 3 and stored, and the total number of bits of the stored data is divided into the number of stitches and the amount of transmitted data is output. Alternatively, the data is stored as is without any data processing, and the total number of bits of the stored data is converted to p9 to determine the amount of data to be transmitted.

Next, in the communication time calculation unit 5, the amount of transmitted data accumulated in the data storage 92 and the data transmission speed and concealment in the communication system H@4 are determined as ii! The 1m required time is calculated (common value required time = data: 1/transmission &), and the calculation result is given as communication*@IH14vc. At the same time, the calculated over-gI required time is auxiliary displayed on the over-reliable time display section 6. In the 0-pass value -44, the over-reliable required time information is given by the over-reliable time calculation section 51P prior to data transmission. to the other station. After that, the data sound data processing s3 is started from the data storage i12! &, and then data is transmitted to the other station through the communication control i1 section 4. In addition, when writing the data from the data storage section 21P to the data processing Y equivalent to the data lI & field section 3, it is necessary to perform -dou processing on the - data. be. In addition, data processing
If a configuration is adopted in which data is stored in the data storage section 20 and data compressed by encoding is stored in the data storage section 2, data processing when writing and reading data as described above can be performed separately. This eliminates the need for data storage and improves data storage efficiency. During data transmission, 1g1lIi!
If it becomes necessary to retransmit the same data due to an error or the like, the communication time calculation unit 5 sends i! If the time required for communication is short, the communication will be performed again, and the time required for communication will be notified to the other station prior to data retransmission.

On the receiver side, the overconfidence control unit 7 detects the communication time information sent from the other station prior to data transmission, and stores the detected communication time information in the communication time storage unit IO. The overreliance time display unit 11 is caused to display the overreliance time of the controller to be transmitted from now on in accordance with the information stored in the memory. Thereafter, the data transmitted from the partner station is received by the overconfidence control unit 7, and the received data is also processed by the data processing unit 8 and sent to the data storage unit 9 to be recorded. become. In addition, communication/9rl! When displaying the time, a down counter is used in the overconfidence time storage unit IO to reduce the stored content in accordance with the clock pulse given every time one minute passes (for example, one minute), and the content of the 70p counter is Accordingly, it is also possible to sequentially display the remaining communication time on the communication time display su.

Mayu, in the overconfidence time display section 11, the overconfidence time memory 11
The time may be displayed by 181'l from the current time in accordance with the required communication time stored in 10.

Moreover, FIG. 113 and FIG. 14 show other embodiments of the present invention. In this case, data amount detection@ 12"!k" is provided on the receiver side as shown in the detected data amount information 411 to calculate the communication time to calculate the average required time according to the data amount information detected by the overconfidence control unit 7 and the data damage speed. A section 13 t- is provided, and the calculated required communication time is stored in a storage section 10 K * and then displayed on a display # 11 K i.

In addition, instead of displaying the required time for 4M on the receiver side, the receiver side converts the standardized data amount, such as the standard number of sheets, according to the data amount information sent from the other station. The standardized data amount V may be displayed.

As described above, the data communication system according to the present invention includes a data storage function t% and a means for determining the amount of data to be sent at the time of data storage in the transmission 111111, the uneven data amount, and the data that runs into the data communication system. This system is constructed by providing a means for displaying the communication time t based on the transmission speed, and a means for displaying the communication time required on the receiver side. It has the great advantage of being able to easily determine when the reception of data transmitted from a station is complete.
