Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention has an input means consisting of a screen display unit such as a CRT, and a pointing device such as a keyboard, mouse, touch panel, etc., and monitors and operates devices and equipment connected to the outside. The present invention relates to an image display device that can also display images.

0002

2. Description of the Related Art Generally, an image display device is used to monitor the operating status of various devices and devices, or to operate them while looking at the screen. In that case, the screen of the image display device will show
It is necessary to construct a screen for displaying operations corresponding to the external device to be controlled. To do this, conventionally, as a program to display an operation screen, the screen to be displayed is described using graphic drawing commands, and then compiled through a compile process.
I was creating drawing information for motion figures.

On the other hand, regarding the data for displaying motion figures, a data information table is created by inputting a data name indicating the location of the data from a tabular definition screen, etc. that corresponds to the motion figure drawing command. was. Alternatively, a data information table is created by writing data names using other writing methods and compiling them. The drawing information and data information table separately created by these processes are loaded into the main body of the image display device. The image display device collects data based on the data information table, and further displays the action by drawing on the screen based on the collected data and drawing information of the action figure. In this way, in the conventional image display device, the data collection process and the display process of the operation display section are completely independent. Furthermore, with conventional image display devices, when attempting to display a screen using special processing on the operation display section, it is not possible to create a regular table such as a data information table. The application was responsible for starting special processing and creating data and displaying the operating parts at the timing of displaying the corresponding display screen.

[0004] Furthermore, when the image display device has a keyboard and an input field for inputting data, or a pointing device such as a touch panel or a mouse, when attempting to perform setting operations such as setting data or issuing operation commands for equipment/equipment, etc. , displays an input field for data settings when the screen is displayed, and performs data input settings. Alternatively, it is also possible to register a pointing area, select that area, and issue an operation command. In that case, it was possible to register the input field display and pointing area in the display unit's description language. Furthermore, regarding setting operations from the image display device side,
The various conditions and safety of the devices and equipment to be operated.
Various operating methods can be used in consideration of operability. For example, even if the pointing area has not yet been set when the screen is displayed, the pointing area will be registered by pressing a specific key on the keyboard.
Furthermore, by selecting that area, an input field is displayed, and data can be entered and set.

[0005] Conventionally, screens for monitoring and operating external devices were constructed by combining multiple behaviors, so it was not possible to write these processes as they were and input them to the image display device. It was possible. Therefore, application processing dedicated to setting operations is usually prepared so that input fields and pointing areas can be controlled arbitrarily. In addition, the user had to individually prepare a table for data setting destinations and operation command transmission destinations by the application.

[0006]

However, the above-described conventional method of constructing a screen for displaying operations has the following problems.

(1) The language used to describe the drawing of motion graphics on the motion display section displayed on the screen and the method for defining the location of data for displaying the motion graphics become independent. Moreover, on the image display device side, the data collection process and the process of drawing motion figures based on the collected data are independent. For this reason, it is difficult to match the collected data with the action figure, and it is difficult to freely display the screen.

(2) In order to display an image as an operation display section, in addition to simply displaying collected data, special processing such as processing the data and converting it into a different form before displaying it, such as trend graph display, is required. When performing these processes, the activation of these processes is dependent on application processing, so it becomes a black box from the user's perspective.

(3) Since there are various methods of setting operations related to the operation display section, a description language alone is insufficient to express these processes, and most of them must depend on application processing, making it difficult for the user to use. was annoying.

(4) Similarly, the user has to prepare individual tables depending on the application regarding the setting destination of data used in the operation display section and the destination of operation commands, which is cumbersome. The present invention has been made to solve the above-mentioned problems, and its purpose is to eliminate the need for troublesome application processing to display the operation display section for monitoring and operating external devices, and to improve usability. An object of the present invention is to provide an excellent image display device.

[0011]

[Means for Solving the Problems] In order to achieve the above object, the first invention is to compile and process an input application program and load it as operating section information, and to obtain data from the location of data indicated by the operating section information. An image display device that collects display data, converts it into a display code, and displays it on a screen, having a means for creating an application program by simultaneously writing a figure drawing command and a data name indicating the location of the motion display data. It is characterized by

[0012] In the second invention, the input application program is compiled and loaded as operating part information, and display data is collected from the location of the data indicated by the operating part information, processed, and then converted into display code. On the image display device that converts the data and displays it on the screen, write the application program by simultaneously writing the figure drawing command, the data name indicating the location of the motion display data, and the timing to start processing the collected motion display data. It is characterized by having a means for creating.

The third invention has an input means such as a keyboard or a pointing device, compiles the input application program and loads it as operation section information, and displays display data from the location of the data indicated by the operation section information. By collecting data, converting it into a display code, and displaying it on the screen, data can be exchanged with the connected external device, and the received data can be displayed on the operation screen to monitor the external device and input from the input means. In an image display device that operates an external device by transmitting transmitted data while displaying it on an operation screen, the image display device has means for creating an application program by simultaneously writing processing for accepting registration of a pointing area and processing for displaying an input field. It is characterized by:

The fourth invention has an input means such as a keyboard or a pointing device, compiles the input application program and loads it as operation section information, and displays display data from the location of the data indicated by the operation section information. By collecting data, converting it into a display code, and displaying it on the screen, data can be exchanged with the connected external device, and the received data can be displayed on the operation screen to monitor the external device and input from the input means. In an image display device that operates an external device by transmitting transmitted data while displaying it on the operation screen, there is a process for accepting registration of a pointing area, a process for displaying an input field, and a process for transmitting the transmitted data to a specified setting destination. The present invention is characterized in that it includes a means for simultaneously writing processes to create an application program.

[0015]

[Operation] In the first invention, the graphic drawing command and the data name indicating the location of the action display data are simultaneously written in the application program, so that the data is unified in one language within the main body of the device. Collection and graphic drawing processing are performed in a single process.

In the second invention, the graphic drawing command, the data name indicating the location of the motion display data, and the timing to start processing the collected motion display data are simultaneously written in the application program. In the main body of the apparatus, data collection and graphic drawing processing are performed in a single process using a single language, and processing of the collected motion display data is started at a designated timing.

[0017] In the third invention, by simultaneously writing the process of accepting registration of the pointing area and the process of displaying the input field, each process is performed in a unified language within the main body of the device. This makes it easier to utilize the standard processing provided on the device itself.

[0018] In the fourth invention, the process of accepting registration of a pointing area, the process of displaying an input field, and the process of transmitting transmission data to a specified setting destination are simultaneously described, so that , each process is performed in a unified language, and the set transmission data is transmitted to the destination using standard processing prepared on the main body of the device.

[0019]

Embodiments Hereinafter, embodiments of the present invention will be explained with reference to the drawings. FIG. 1 is an explanatory diagram showing the process of an embodiment in which the first invention is applied to an image display device using a CRT. As shown in the figure, as an application program, first, the action display data to be displayed is made into graphic drawing commands for each screen number, character attributes such as character color, character font, character magnification, background color, etc. are described, and then the data is displayed. Create a source file by describing coordinates, data type, data name, display digits, decimal point position, etc. as character display. Next, the created source file is compiled and converted into a graphic drawing information file and a data collection information file, which are operating unit information. Display color, character font, character magnification, background color, display coordinates, data type, display digit, decimal point position, etc. are written in the graphic drawing information file. In the data collection information file, the name of collected data, the size of collected data, and the number of collected data are written.

Next, these files are loaded onto the CRT display device 1. Everything up to this loading is processed offline. Specifically, after a source file is created and compiled using a personal computer or the like separate from the CRT display device 1, it is loaded into the CRT display device 1 via an RS232C standard communication cable or the like. When the CRT display device 1 is instructed to display an image of the loaded file using the screen number,
Data collection processing is started according to the data collection information file with that number. In the example, it is written in the specified data collection information file that data each having a length of 1 word is to be collected with the collection data names "TEMP1" and "HUMD1". data is collected from the external air conditioner 3. The air conditioners 3 each have a temperature (TEM) detected by the thermometer 4.
P1) and the humidity (HUMD1) detected by the hygrometer 5 are stored in an internal file, and then stored as "collected data" in response to a call from the CRT display device 1.
send to

Next, the CRT display device 1 edits the collected data according to the graphic drawing information file so that it can be actually displayed on the screen, converts it into a display code, and sends it to the CR.
Display on T2. In the embodiment, the collected data is displayed in two decimal digits at designated coordinate positions on the CRT 2, and a word or phrase specifying the content of the data is displayed as a background. In the process of displaying these images, the display contents for each screen number are specified in the source file in advance and then loaded into the CRT display device 1, so that the operator can simply input the screen number. Various screens can be displayed.

[0022] Furthermore, since the data collection process in the CRT display device 1 is carried out using data names, data addresses, which were necessary in conventional processes, are no longer required, and the burden of input operations on the user is reduced accordingly. . Furthermore, when the data collected and displayed on the CRT 2 changes, the data displayed on the screen is also immediately changed because the collection process and the editing process are sequentially executed.

FIG. 2 is an explanatory diagram showing the processing process of the second embodiment of the invention. This embodiment performs almost the same processing as the embodiment of the first invention, but especially in this embodiment, a trend graph can be displayed from the collected data. If you want to display a trend graph, write the trend graph display command, which is a processing command, in the source file, the name of the data to be displayed in the graph, and the format for displaying the graph, as shown in Figure 2. . Next, this source file is compiled and converted into a graphic drawing information file and a data collection information file. Display commands and formats for trend graphs are written in the graphic drawing information file.
The data name to be displayed in a graph is written in the data collection information file. Next, these files are loaded onto the CRT display device 1.

When the screen number of a file instructing trend graph display is input, the CRT display device 1 starts trend processing according to the timing described in the data collection information file of that number. In trend processing, trend data is collected from a trend file 24 that has already been uniquely compiled as data for trends based on the data name written in the data collection information file, and edited into a designated format. Next, the editing result is converted into a display code and displayed on the CRT 2. Note that the displayed trend graph may be a graph displaying data collected in advance all at once, or a graph displaying sequentially collected data plotted one point at a time. In the former case, the display content of the graph does not change because the number of data display points for the graph to be displayed is determined in advance. On the other hand, in the latter case, the graph is displayed while increasing the number of display points as time passes, so if the display limit is exceeded, it is necessary to redraw the graph midway. The timing of this redrawing can also be arbitrarily set by writing it in advance.

FIG. 3 is an explanatory diagram showing the process of redrawing the trend graph displayed on the CRT 2. In the figure, the number of display points gradually increases, and when the graph reaches the right end of the horizontal axis, the number of display points reaches its limit and is redrawn. As a result of redrawing, the horizontal axis scale is 3.
The display graph is changed to 3x in the horizontal axis direction.
It is displayed reduced to one-fold. This makes it possible to continue displaying the collected data from now on.

As described above, in the embodiment of the second invention, when a screen number is designated by an input operation, unique trend processing is immediately started within the CRT display device 1 without performing processing such as collection or editing. This eliminates the need for complicated and troublesome input operations to display graphs as in the past. In addition to trend processing, which is not shown in the examples, processing processing that is started independently without processing such as collection or editing is also possible.
Similarly, after creating a source file by inputting commands related to figure drawing and processing using a descriptive language,
It is possible to load it into the RT display device 1.

Next, the third and fourth inventions will be explained. FIG. 4 is an explanatory diagram showing the processing steps of an embodiment in which the third and fourth inventions are applied to an image display device using a CRT. As shown in the figure, for each screen you are trying to display,
As an application program, a description language source file is created by writing setting/operation information and the location of the data setting destination. Next, the created description language source file is compiled and converted into a setting operation information file and a setting destination information file, which are operation unit information. The settings operation information file contains information such as management number, initial mode, display coordinates, etc. using various drawing commands to construct the screen.
Function codes etc. are written. In the setting destination information file, the destination when data is set by an input operation is written with a specific name as destination data. Next, these files are loaded onto the CRT display device 1. Processing up to this loading is done offline.

A CRT 2 for displaying a screen is connected to the CRT display device 1, and a CRT 2 is connected as an input means.
A keyboard 8 is connected to a touch panel 6 and a mouse 7, which are pointing devices installed on the screen of the RT2. Further, an air conditioner 3 is connected to the CRT display device 1 as an object to be monitored and operated.
1) and the humidity detected by the hygrometer 5 (HUMD1) are sent to the CRT display device 1, and an operating signal for the air conditioner 3 is sent from the CRT display device 1 side. The CRT display device 1 also stores graphic drawing information 9, data collection information 12, and a display code converter 13 that are input separately, and also includes a display code converter 13 that converts these stored information into display codes. , and an input device management section 14 that manages various connected input devices.

In this embodiment, the following description language is used for inputting to the CRT display device 1. ■Input field (number, initial mode, position, number of digits, display symbol, location of setting destination) ■Touch (number, initial mode, area, function code) ■Mouse (number, initial mode, area, function code) ■Selection input Field (number, initial mode, position, display symbol) { Input field (number, initial mode, position, number of digits, display symbol, setting location) or touch (number, initial mode, area, function code) or mouse (number , initial mode, area, function code) } ■Selection touch (number, initial mode, area, function code) { Input field (number, initial mode, position, number of digits, display symbol, setting location) or touch (number, Initial mode, area, function code) or mouse (number, initial mode, area, function code) } ■Selection mouse (number, initial mode, area, function code) { Input field (number, initial mode, position, number of digits, display symbol, setting location) or touch (number, initial mode, area, function code) or mouse (number, initial mode, area, function code) }

It should be noted that the screens displayed in the languages ``■'' to ``■'' have one screen with one behavior, whereas the screens displayed in the languages ``■'' to ``■'' have two behaviors. In other words,■
According to the language ~■, when an input operation is performed on the first displayed screen, the behavior is to wait for any input operation selected within {}. Furthermore, the "number" written in the above description language is a management number that is consecutively assigned to each written language. Similarly, the "initial mode" is either "enabled" or "disabled", and is established for operational safety, and enables input operations performed on the screen immediately after the screen is displayed in that language. You can set whether to enable or disable it. "Position" is the coordinate of the location where the input field is set. “Number of digits” indicates the number of characters that can be input as an input field. “Display symbol” refers to an under cursor etc. displayed in an input field. “Setting destination location” indicates the setting destination of input data by a specific name. “Area” specifies the range on the screen that accepts input. “Function code” is
This is the specific code name that occurs when an input operation is performed.

FIG. 5 shows an example in which a description language source file is compiled, and as a result of the compilation process, the description language source file is divided into a setting/operation information file and a setting destination information file. In the setting/operation information file, the number is written on the first line, and the description contents of the source file are written in order, such as the number of behaviors and the initial mode on the next line. The input data storage area at the lowest level is used to temporarily store data such as numbers input while the contents of this file are displayed on the screen. The setting destination information file describes the setting destination of the input data specified by the input field along with the number corresponding to the setting/operation information file.

Next, the processing operation of the embodiment shown in FIG. 4 will be specifically explained. First, input the following contents as a description language source file. <Description language source file> Select touch (10, initial invalid, x1, y1, x2, y2
, 1234H) { input field (12, initial invalid, x3, y3, 2, “
”, TEMP1) }

The settings/operation information file and setting destination information file shown in FIG. 6 are obtained by compiling this file. At this point, the input data storage area at the lowest level of the setting/operation information file is all "0" because no data has been input yet. These files are then loaded into the CRT display device 1 and become setting/operation information 10 and setting destination information 11.

Next, after loading as shown in FIG. 7, the temperature detected by the thermometer 4 (TEMP1) and the humidity detected by the hygrometer 5 (HUM
D1) is configured on the screen in a form specified by the graphic drawing information 9, is converted into a display code by the display code converter 13, and is displayed on the CRT 2. In the figure, the number “30”
and "55" are displayed as collected data 17a, 17b. In this state, touch the number (10) in the loaded setting/operation information 10 and touch the number (10).
Since the initial modes of the input fields 2) are both invalid, screen operations on the touch panel 6 on the CRT 2 are in an invalid state.

FIG. 8 shows the next state in which the "setting" key on the keyboard 8 is pressed. When the "setting" key is pressed, a "setting" function code is sent to the input device management section 14. In setting/operation information 10,
When the input device management unit 14 notifies the input of the function code, only the initial mode of the touch number (10) is changed to effective. Next, the input device management section 14
Based on the described position data, the range surrounded by the two points (x1, y1) and (x2, y2) on the touch panel 6 can be registered as the touch area 18, which is a pointing area. Note that this touch area 18 is not actually displayed.

FIG. 9 further shows the next operation. When the set touch area 18 is touched with a fingertip, a function code of "touch 10" is sent to the input device management unit 1.
Sent to 4. In the setting/operation information 10, when the input device management unit 14 notifies the input of a function code, the initial mode of the input field numbered (12) is changed to valid. Next, the display code for the input field numbered (12) is sent from the display code converter 13 to the CRT 2 according to the description content, and is placed at the specified position (x3,
y3). The displayed input field 19 consists of two digits, each underlined.
Initially, a cursor 20 is displayed at the first digit.

FIG. 10 shows the operation for inputting the following setting values. When the numeric keys "2" and "3" on the keyboard 8 are pressed in sequence, codes "2" and "3" are sent to the setting/operation information 10. These input codes are once stored and then converted into display codes by the display code converter 13.
The data are then sent to the CRT 2 and displayed in the input field 19 in the order in which they were input.

FIG. 11 shows the operation of transmitting the next set value. When the "send" key on the keyboard 8 is pressed, a "send" function code is sent to the input device management section 14. Next, the setting values “2” and “3” stored in the setting/operation information 10 are set by referring to the setting destination information 11,
It is sent to the thermometer 4 via the already loaded setting destination "TEMP1", that is, the air conditioner 3. From then on, the air conditioner is operated to maintain the set temperature of 23 degrees. After the setting value is sent to the specified setting destination, the number (12
) is changed to invalid, returning to the state of FIG. Thereafter, if other input fields are set, other setting operations can be continued. In this embodiment, the setting operation for up to two behaviors has been described, but the setting operation can be similarly performed for three or more behaviors by specifying them using the description language.

As is clear from the above operations, in this embodiment, the application program previously performs processing for registering the touch area 18 which is the pointing area, processing for displaying the input field 19, and processing for inputting data. By loading the transmission data to the destination "TEMP1" into the CRT display device 1 as setting/operation information 10 and setting destination information 11, each operation screen is constructed, and settings are made based on this screen. Value input operations can now be easily performed through extremely simple input operations. Although the CRT screen 2 is used as the screen display device in the embodiment, the present invention can be similarly applied to other screen display devices using liquid crystals or plasma displays.

[0040]

[Effect of the invention] As described above, according to the first invention,
By simultaneously writing the drawing command and the data name indicating the location of the operation display data in the application program, the user no longer needs to prepare separate tables for data setting destinations and operation command destinations, and input operations This also simplifies the screen display program, making it possible to standardize the program.

According to the second invention, a graphic drawing command, a data name indicating the location of the motion display data, and a timing for starting processing of the collected motion display data are simultaneously written in the application program. This makes it possible to create complex programs such as trend display with simple descriptions. Further, as in the first invention, the input operation is simplified, the screen display program is simplified, and the program can be standardized.

According to the third invention, by simultaneously writing the process of accepting pointing area registration and the process of displaying an input field, various types of processing can be performed using standard processes prepared on the main body of the device. It is possible to construct screens with excellent operability that correspond to settings and operation styles.

According to the fourth invention, the process of accepting registration of a pointing area, the process of displaying an input field, and the process of transmitting transmission data to a specified setting destination are simultaneously described, so that the user can Configuration data can be sent to a specified destination without preparing an application table.

Further, according to the first to fourth inventions, compared to conventional devices in which each process is input individually, the user side does not have to prepare an application that is complicated and troublesome to operate.
Actual screen operations can now be performed with simple input operations, and an image display device that is highly user-friendly can be obtained.
