Abstract

PURPOSE:To form a program which can cope with a larger scale system and does not disturb its service by providing a memory selector for judging which of two refresh memories, to write data in, and selecting the two memories according to their usage. CONSTITUTION:Data from a computer is first sent to an input/output controller 5, sent as output data to a display data controller 6, which judges whether the data is to be displayed on a console or not, i.e., whether the data is to be stored in a refresh memory of the console or not. The data judged to be displayed is loaded in any of first and second refresh memories 9, 10 by a memory selector 8 in a display controller 7. The loaded data are always formed in a structure in which the data is interposed between an EF-LOAD command and an EF-TERM command. The data interposed between EF codes is refreshed by a refresh controller 11 to become a tracing symbol, line, circle, ellipse on a CRT monitor by a symbol generator 12.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tactical display device and device for controlling a man-machine interface in a combat command system of a guard ship.

[Conventional technology]

FIG. 2 shows a conventional tactical display device (display console).

The console operator operates a console panel on which various buttons, switches, etc. are arranged, and the result of the operation is input as a th function code to the computer α through the panel control device aη and the input/output control device α. The computer (14) decodes the operator's command using this function code and sends the response to the display console as output data.The output data from the computer I is first sent to the input/output control device A, where the display data is output as output data. The controller (11) judges whether the data should be displayed on this console and sends only the data that should be displayed to the display control unit.The data sent to the display control unit is stored in the refresh memory auc. It is stored and periodically refreshed by a refresh controller (2).

The refreshed data is generated by the symbol generator @line, circle. It is converted into tactical figures such as ellipses and track symbols, and displayed on the CRT monitor T2 trench.

Figure 3 shows all memories that refresh computer output data.
) is an IP' (external function) codeword format for loading.

The EF code is set to EF-LO according to the instructions of bits ts and iy.
The AD command and the EF-TERM command l'K can be distinguished, and the EF-LOAD command can be further divided into two types: a top-down method in which data is written from the top of the refresh memory, and a bottom-up method in which data is written from the bottom. EF-LOAD command and EF-T
ERM command)'K id Only the sampled portion is refreshed by the refresh controller (2) and displayed as a symbol on the CRT. Note that the refresh memory e29 cannot specify a specific memory at 1 node, and has an interface that always writes from the top or bottom of the memory.
If this is sent out as output data, all previously displayed graphics will be erased from the CRT monitor Q4. That is.

The specifications for program processing within a 1-tatami computer require data to be sent in the form of adding new data to previous data.

Conventionally, in the Japanese and U.S. combat command systems, all display data is written in a top-down manner to the refresh memory @, which is only one in each display console, and system-common data is written to the console designated as shown in Figure 4. without adding the address word. As for console unique data, a method has been adopted in which an at1/sword is added to each data for displaying one graphic, and the data is displayed only on that console.

[Problem to be solved by the invention]

However, in a conventional system using a conventional device, all system common data and console unique data were loaded into one refresh memory by sandwiching them between EF-LOAD and EF-TERM commands. The amount of computer data sent at one time was enormous, and the time occupied by I10 due to data transfer reached the system's limit, resulting in the following problems.

System parameters (number of target tracks being tracked, number of tactical figures, etc.) t- cannot be increased beyond the current level, so no further system construction (new connection with external equipment, etc.) can be performed.

Therefore, the present invention aims to make the following possible.

The maximum amount of tactical information that can be displayed on the console will be doubled, while keeping the total amount of data sent the same as the current amount.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a tactical display device. The display control unit is equipped with a memory selector that determines whether data is to be written to one of the two refresh memories. Means for writing to memory, the refresh controller defines the undefined bit of the EF code as refresh select, and refreshes the memory specified by the value in the upper part.

It has means for allocating two selectable refresh memories according to the purpose of data.

[Effect]

In the present invention, since the two refresh memories are used differently depending on the purpose, it is possible to create a program that is compatible with a larger scale system and does not hinder operation.

〔Example〕

FIG. 1 is a functional diagram of the hardware in the tactical display device of the present invention.

The console operator operates the console panel (331), and the result of the operation is read into the computer fl via the panel control device (4) and input/output control device (5) as a 32-bit funxilon code. The computer (11) analyzes this function code and recognizes what action the operator has taken.

The computer's response to an operator action is a trail symbol, a line. circle. This is a CRT monitor display of tactical information consisting of ellipses and the like. The computer (1) sends data to the display console to display information, but the data sent from the computer (2) is first sent to the input/output control device (5), and from there it is sent as output data to the display data control device (5). 6)
Sent to. Whether the data should be displayed in this console. That is, it is determined whether the data is to be stored in the refresh memory of this console. The data determined to be display data is processed by the memory selector (8) in the display control unit (7) as a first paste fresh memo (January 9).

It is loaded into one of the second glue fresh memories fiG. Loaded data must be EF-LOA
D command and EV-TERM command [must be a structure trap sandwiched between them.

The data sandwiched between the EF codes is refreshed by the refresh controller aD, and the data sandwiched between the EF codes is refreshed by the refresh controller aD.
z is displayed on the CRT monitor in the form of a track symbol, line, circle, or ellipse.

FIG. 3 is a word format of an EF code for loading data into fresh memory.

The fiEF code is EF' due to the value of bits 18 and 17.
-Is it a LOAD command? EF-TERM command or. The EF-LOAD command determines whether data is loaded from the top of the fresh memory (top-down) or from the bottom (bottom-up). Bits 15 and 27 are memory load select bits that specify which of the first and second refresh memories data is to be loaded into. t4 is a refresh select bit that specifies the memory to be refreshed. FIG. 5 shows how data sandwiched between EF codes is loaded into the refresh memory in both a top-down and bottom-up manner.

FIG. 6 is a diagram showing a display method according to the present invention. This figure shows the data sending process among the program processes within the computer.

In step (2), it is determined whether the data is common to all consoles or unique to the console. IF if it is common data
The first refresh memory is selected in step (a) by bit manipulation of the code, and all console output is specified in step (ii). If it is console unique data, select the second refresh memory in step (to). In step (to), turn off all console output specifications and set the hardware-configured console address to the console. Then it is connected to the console! Data transmission in step (1) is performed by applying an output trigger to the Oki channel.

〔Effect of the invention〕

According to the method and device of the present invention, the amount of display of 0 tactics can be doubled, completely satisfying operational requirements.

This has the effect of making it possible to construct a large-scale combat command system.
