Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to data terminal devices or data processing devices that can be connected to each other from a side that sends data (hereinafter referred to as the center side) to a side that receives data (hereinafter referred to as the center side).
This relates to a data transmission method for easily and accurately transmitting data to the terminal (terminal side).

When transmitting data between data terminals or data processing devices, in order to accurately transmit data from the center side to the terminal side, control for transmission such as checking the transmission destination and checking whether the transmission/reception status of the other party is good or not is necessary. It is necessary to do it. This control is generally called transmission control and requires complex control operations.

In addition, in actual data transmission, the center side must control the structure of the message to be transmitted, the transmission order, etc. in advance, and the burden of control operations for data transmission is greater on the center side than on the terminal side. There is a tendency to Furthermore, on the terminal side, it is almost impossible to know what kind of message structure will be transmitted and for how long, and after actually receiving and storing the data, it is necessary to check the message type (control message or information message). It also required an action to check the purpose of the message. Therefore, how to process received messages on the terminal side depends on the terminal receiving all the data.
Since the decision is made after checking, there is a drawback that the processing takes time. In this way, the terminal side performs data memory check processing, data identification processing, etc., resulting in drawbacks such as complexity in device configuration and control operations, and the need for a large amount of processing time.

This invention shows at least the processing order of the original message before transmitting the message, and if necessary, the original message configuration, data length, etc.
The purpose is to reduce the burden on equipment configuration and control operations on both the center side and the terminal side, and to shorten the processing time of received data on the terminal side, by sending a notice message (in the form of a template message) informing the purpose of the message etc. The objective is to provide a data transmission method that allows for The data transmission system of the present invention will be explained below.

In the method of this invention, when a message is sent from the center side to the terminal side (or vice versa), a preview message is transmitted before the actual message is sent. FIG. 1 shows an example of the structure of a message according to an embodiment of the present invention, and the message consists of header data 1 and data content 2 indicated by the header data 1. FIG. 2 is a configuration diagram of header data 1. That is, header data 1 indicates the type and length of the following data 2, and header marks 3,
It consists of a destination number (for example, a terminal number) 4, a message type (representing the type of message) 5, a block type (representing the composition state of the message) 6, a message data length 7, and an empty area 8 as required. Message type 5 indicating the type of message is a notice message;
It is used to distinguish types of messages such as (chicken-shaped telegrams), text messages, and voice messages. For example, codes 0, 1, and 2 are assigned to advance notice messages, text messages, and voice messages, respectively. Block type 6 is used to indicate when the message is divided into several blocks and transmitted, such as beginning, middle, last, beginning and last (in the case of one block and one message). For example, codes 0, 1, 2, and 3 are assigned to the first block, middle block, last block, and first and last block, respectively.

The structure of the notice message (chicken-shaped telegram), which is a feature of this invention, is, for example, as shown as 9 in FIG. It is 3. Further, C or V in the data 2 indicates a break in the structure of the original notice message, and defines the processing order and type of the message. That is, C represents character information, V represents voice information, and at the same time also represents the processing order. In other words, the original messages following data 2 of the nested message 9 in FIG. 3 are data 1 and 3 of the text message 10 and data 2 and 4 of the voice message 11. It is shown that the data are processed in the order of 4 and the length of each data.

In the present invention, the chick-shaped telegram 9 is sent from the center side to the terminal side before transmitting the message 10 or 11. That is, for example, as shown in FIG. 4, in the center 12, a message creation unit 13 creates a template message 9, and sends it to the terminal 15 via a transmission line 14 such as a channel line, public telephone line, or dedicated data line. At the center 12, after transmitting the basic message 9, the original message is created in the message creation section 13 and transmitted to the terminal 15. If the received message is a text message 10, the terminal 15 outputs it to the printing device 18 through the text message converter 16,
In the case of voice message 11, voice telegram conversion unit 17
It is output to the audio output device 19 through.

The content of the message 9 received by the terminal 15 enables advance preparation for processing the original message that will be sent later, such as preparation for display, preparation for printing, preparation for voice conversion, etc. This facilitates control operations such as printing, displaying, voice conversion, etc. for messages received after the chick-shaped telegram 9. Also, compared to transmission methods that require checking the message again after receiving it, the center side has already informed the terminal side of the message processing order, so there is little need to consider the message sending order. gone,
Since messages can be sent out of order, for example, text message data 1 and 3 can be sent consecutively, as in the example shown in Figure 3, in other words, data of the same type can be sent all at once, regardless of the processing order. This has the effect of simplifying the configuration and operation control of the device.

Conventionally, header data was sent for each piece of data and sent as one message, and it was not possible to send multiple pieces of data in one message. However, in this embodiment, each data 1 to 4 is
Since the length of data 1 and 3 is sent, even if multiple pieces of data 1 and 3 are sent in the same message, they can be separated. As shown in Figure 2, header data 1
By providing an unused portion 8 within the memory, this unused portion 8 can be used for expanding processing in the future. However, this unused portion 8 may be omitted and the length of the header data 1 may be set to 6 bytes.

As explained above, the data transmission method of the present invention can be used not only for general data transmission, but also for data transmission where voice messages (converted into speech on the terminal side) and text messages are mixed. , the effect can be expected.
