Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a light control device that displays a light control state on a CRT screen.

[Background technology] Conventionally, in this type of dimming device, the location of the load (for example, on the stage), dimming control mode (dimming control state, direct lighting state, lighting disabled state), lighting level, etc. It is designed to be displayed on a CRT screen installed at

Part B within the broken line in FIG. 1 shows the conventional configuration, and when an operation input such as a fader operation is sent from the dimming operation section 1 to the dimming control section 2, the dimming control section 2 performs the operation. A dimming instruction signal according to the input is sent to the dimming signal output section 3. The dimming signal output section 3 outputs a dimming level signal and a circuit designation signal according to the instruction signal, and the dimmer 4 designated by the circuit designation signal receives the dimming level signal and applies the actual load. Control power. At this time, the display control unit 5
receives the above-mentioned dimming level signal and circuit designation signal, and sends a signal for displaying the dimming state to the display unit 6.

As a display control method, a method is used in which display format data stored in the main storage section 7 in advance is used to convert dimming data into a display signal.
Display format data includes information such as what type of characters or figures to display dimming data on the display, what colors to use in the case of color display, and where on the display screen to display it. Normally, a ROM (read only memory) is used for the main storage section 7, and display format data is written using a dedicated writing machine (ROM writer) that is separate from the light control device.

However, in actual stage lighting production,
The number and arrangement of loads often change each time the device is used, and there are also many requests to change the names and display colors of loads depending on the preferences of directors and operators. When a user makes such a request, the manufacturer needs to convey the request to the designer, have them change the display format data, and then convey that data to a specialized engineer to have the contents of the ROM rewritten. In fact, it was extremely difficult to respond to each individual request.

[Object of the Invention] The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a light control device that allows the user to easily change the above-mentioned display format data. There is something to do.

[Disclosure of the Invention] The light control device of the present invention includes a display section capable of displaying an image that displays figures and characters corresponding to light control data at a display position corresponding to the location of a load, and a display signal to the display section. a rewritable storage section that holds display format data including at least a graphic format corresponding to the load and a display address of the display position, and an input for setting the display format data. a format data reading section that selects a graphic format preset according to the load in accordance with instructions from the input section; and a display that indicates the display position of the format data in accordance with instructions from the input section. This device is characterized by having a display address setting section that assigns an address, and a display data writing section that writes display format data including format data and display addresses into the storage section. This allows the user to freely set or change display format data that had previously been changed upon request.

FIG. 1 shows an embodiment of the device of the present invention, and a portion B surrounded by a broken line has almost the same configuration as the conventional one, but the main memory 7 has a ROM instead of a ROM.
It uses RAM. In the figure, a display format data setting input section A for setting display format data includes a display address/color input section 8 for specifying a display position and display color, and a character input section for inputting a load name, etc. 9, and a circuit designation section 10, which will be described later.
It is made up of. The sub storage section 11 is composed of a ROM, and has format data written therein for converting the display address signal or display color signal inputted from the display address/color input section 8 into display format data. The format data is read into the display address/color setting section 13 through the format data reading section 12. The circuit designation section 10 described above is for designating the circuit (load) for which the display format is to be set and instructing the reading of format data. The data is written to the main storage section 7 via the display data writing section 14. Further, in the character data editing section 15, the character code input from the character input section 9 is converted into a display character code, and written into the main storage section 7 via the character data writing section 16. Furthermore, the display format creation control unit 17 controls the operations of the format data reading unit 12, display address/color setting unit 13, display data writing unit 14, character data editing unit 15, and character data writing unit 16, and also This is for instructing the display control section 5 to display a prompt for creating display format data, and the display format creation instruction control section 18 receives a predetermined signal from the dimming operation section 1 to create a display format. This is for sending a start signal for creating a display format to the control unit 17. Further, the communication control section 19 is for transmitting and retaining the contents of the main memory section 7 to an external storage section 20 consisting of a floppy disk or the like. Furthermore, the main memory section 7
It is also possible to omit the external storage section 20 by configuring it with a CMOS type RAM and using a battery to retain memory when the power is turned off.

In the embodiment shown in FIG. 2, the display format data setting input section A shown in FIG. 1 is also used as a full keyboard of the dimming operation section 1.

FIG. 3 shows the operating state of the device of the present invention. (a) is the procedure for setting the display address and display color; when the circuit designation signal is input in (a), the format data is read in (b), and the display waits for the display address and color input in (c). When the display address/color signal is input, the display address and display color are set in D and E, and display pattern data is written to the designated circuit in F. (b) shows a character input procedure, in which characters are input and edited in G and G, and when an end code is input, character data is written into the main memory section 7 in R. In this way, setting of the display format data is completed by setting the display pattern according to (a) and setting character data according to (b).

[Effects of the Invention] As described above, the present invention allows a user to freely set display format data in a dimming device that is equipped with a storage unit that holds display format data for converting dimming data into a display signal. Because the means have been established,
In addition to being able to quickly respond to changes in the number of loads and rearrangement of loads, the dimming director and operator can set the load display position, display color, load name, etc. on the display screen according to their own preferences. It has the advantage of being able to That is, format data is given to a display unit capable of displaying an image so that the load can be displayed using not only characters but also figures, and the location of the load can be displayed in correspondence with the position on the image. Because the address is given, it is possible to clearly identify which load is set to which dimming state on the display screen, improving operability. Since the display can be freely changed according to the situation, it has the effect of being particularly effective in stage lighting and the like.
