Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention has a configuration in which #l terminals are distributed via a communication network, and an appropriate one is selected from commands input almost simultaneously from each terminal. This relates to an input control method that selects and executes one command.

[Prior Art and Problems to be Solved by the Invention] Conventionally, a method has been adopted in which communication control between terminals distributed in a network is performed using a communication authority that manages the terminals. The control method for input from multiple terminals is method C, in which commands are executed in order from the terminal input first.
time priority management) and a method in which priorities are defined in advance between terminals and commands from terminals with higher priority are executed first (
Device priority management).

The former method has advantages such as easy control and orderly processing order, but has the problem that urgent commands are forced to wait until the execution of the previously input command is completed. The latter method is one way to solve this problem, but it has the problem that urgent commands from terminals with low priority still have to wait. One possible solution to this problem is to use commands with added urgency, but this would increase the number of input items such as numerical values and characters corresponding to the urgency, and each command would tend to use a high urgency level. There were problems such as the setting being a mere facade.

The present invention aims to solve the above points,
The purpose of this invention is to smoothly perform processing for extracting the same data from the multimedia data storage units of n number of terminals and outputting it simultaneously.

[Means to solve the problem]

In the present invention, commands are divided into multiple ranks based on 9M steepness, and communications are controlled using terminal priority management for commands belonging to lower ranks, and time priority management for commands belonging to higher ranks9. In the present invention, the "output stop (cancel)" command is the only command with a high emergency level, and all other commands such as "output next address data" and "output previous address data" are ranked with a low emergency level. In addition, the mask and slave priority relationship are defined in @Shuma, and the “output stop” command is defined.
The main feature is that the command gives priority to the command from the terminal input first regardless of the priority relationship, and the other commands are controlled to give priority to the command from the masked terminal.

〔Example〕

FIG. 1 shows a processing flow of an embodiment of the present invention. First, it is determined whether or not a highly urgent command is included among the commands input from a plurality of terminals.

If it is included, only one of the instructions with the highest degree of urgency is selected and executed. If not included, the command issued from the terminal with the highest predetermined terminal-specific priority is selected and executed.

Each terminal autonomously issues commands at fixed time intervals T according to predetermined rules. If there is no input from the terminal, the data retrieved by this command is output in chronological order. This is the so-called idling state, which is the 0th order, and if there is an input from either the mask terminal or the slave terminal, and the other is in the idling state, the command of the input terminal is executed. When inputs from the mask terminal and the slave terminal are simultaneous, the control method described above is used to determine which terminal's input is given priority depending on the type of command.

This method differs from conventional techniques in that each terminal issues a command spontaneously and that terminal priority management and time priority management are selectively used depending on the urgency of the command.

is the mask terminal, 2 is the line, and 3 is the TSDN network (
communication network), 4 is the line.

5 is a slave terminal.

The mask terminal 1 and the slave terminal 5 are connected via a communication network 3 via a line 2.4.

Data input from the mask terminal 1 or the slave terminal 5 and stored in each terminal can be retrieved.

FIG. 3 is a block diagram showing one embodiment of the mask terminal 1, where 11 is an input section and 12 is an input conversion section.

13 is an output section, 14 is a multimedia data storage section, 1
5 is an interlock control section.

The input unit 11 is a part for inputting data search, and is inputted using a keyboard or the like. Although a keyboard is cited as an example of the input means, other devices such as a touch panel, a voice recognition device, a single character recognition device, etc. may also be used. The input conversion unit 12 is a part that converts the input from the input unit 11 into a command for data retrieval. In contrast, it is converted into an instruction to search for "data at the previous address."

The output unit 13 is a part that outputs data taken out from the multimedia data storage unit 14, and is outputted by a display, a speaker, etc.

The multimedia data storage unit 14 is a part that multiplies search data.

For example, there are still images, moving images, audio, music, nine documents, etc.

The interlock control section 15 is a main component of the present invention, and its operation will be explained in detail below.

(1) Mask terminal 1. In a state where there is no input, both slave terminals 5 spontaneously issue commands according to a predetermined rule at fixed time intervals T, and output data retrieved from the multimedia data storage section I4 to the output section 13.

Mask terminal 1. Communication control for obtaining the same output from both slave terminals 5 is shown in FIG. In FIG. 4, when a timeout of 1 hour T occurs, the mask terminal 1 transmits the command 'X (automatic search for data at the next address)', and the slave terminal 5 sends the command 'X' (automatic search for data at the next address) after receiving 'X'. Search) ゛ and sends ACK to masked terminal l while executing command ゛F'. After receiving ACK, masked terminal l
Execute instruction 'X'. Since 'X' of the mask terminal 1 and F' of the slave terminal 5 are executed at the same time, the outputs of both are linked.

(2) When there is an input from the mask terminal 1 and no input from the slave terminal 5, the slave terminal 5
While the data is being retrieved spontaneously, a command from the mask terminal operator interrupts and causes the command from mask terminal 1 to be executed. Mask terminal 1. Communication control for obtaining the same output from both slave terminals 5 is shown in FIG. In FIG. 5, the command 'F° transmitted from the mask terminal 1 is received by the slave terminal 5.

After sending ACK to mask terminal 1, both terminals issue command ゛F
Since ° is executed, the outputs of both are linked.

(3) When there is no input to the mask terminal 1 and there is input from the slave terminal 5, the same processing as in (2) above is performed and the command from the slave terminal 5 is executed, so the outputs of both are linked.

(4) Mask terminal 1. In a state where both slave terminals 5 have input and the commands are different, if the command is other than "P (stop output)", the command from mask terminal 1 is selected as the execution command and executed. . FIG. 6 shows communication control for obtaining the same output from mask terminal 1 and slave terminal 5. In FIG. 6, in response to command 'F' from mask terminal 1, command 'B (
Search for previous address data) is entered.

The mask terminal device rejects the received command °B", and the slave terminal 5 replaces the command °B ° with the received command °F ° and then sends ACK to the mask terminal l. Both the mask terminal 1 and the slave terminal 5 accept the command. F° is executed at the same time.

(5) Master terminal 1. If there is input to both slave terminals 5 and the command of mask terminal l is °P (stop output) °, and the command of slave terminal 5 is other than °P゛, mask terminal l
The instruction 'P' from is selected as the execution instruction and executed. FIG. 7 shows communication control for obtaining the same output from both the mask terminal 1 and the slave terminal 5. In FIG. 7, when the command °F° from the slave terminal 5 is input in response to the command °P' from the mask terminal l, the mask terminal 1 rejects the received command "F', and the slave terminal receives the command °F". After replacing F゛ with the received command °P°, mask ACK from terminal 1.
Send to. Mask terminal 1. Both the slave terminal 5 and the command °P' are executed.

(6) Mask terminal 1. If there is an input to both slave terminals 5 and the command of masked terminal 1 is other than °P', and the command of 2 slave terminals 5 is P°, the same process as in (5) above is performed and the command from slave terminal 5 is executed. do.

In this way, the outputs of the mask terminal 1 and the slave terminal 5 can be controlled in conjunction.

In this embodiment, the command to be managed with time priority is
Although only ° is used, it is also possible to use other instructions or to use a plurality of instructions.

Furthermore, in this embodiment, it is assumed that two terminals are connected to the communication network, but N (N22) terminals are connected, and there are inputs from M (M≦N) terminals, and 1M terminals are connected.
If all the instructions obtained by converting inputs belong to a rank of low urgency.

Execute the command of the terminal with the highest priority specific to a predetermined terminal on N terminals and select K (K≧1) among the 2M commands.
If the instructions belong to a rank of high urgency, it is possible to expand the process to execute the instruction inputted first among the instructions on N terminals.

〔Effect of the invention〕

As explained above, according to the present invention, commands issued by a terminal are divided into commands for time-priority management and commands for terminal-priority management, and highly urgent commands are divided into time-priority management commands and low-urgency commands. Since this is set as a command for terminal priority management, there is an advantage that the process of simultaneously outputting the same data from the multimedia data storage section of each terminal can be carried out smoothly in normal times and quickly in an emergency.

In addition, each terminal is controlled to extract and output data according to predetermined rules at fixed time intervals, so different data is automatically output one after another without the need for any operation by the terminal operator, saving labor. It has the advantage of being configurable.
