Abstract

PURPOSE:To attain easily a large size display part by arraying pilot lamps such as light emitting diodes in multiple stages and multiple strings and combining the lighting and no-lighting of these lamps. CONSTITUTION:A display pattern showing the operating state of a control system is read at a reading part 1 and supplied to a control part 2 containing a microporcessor to be stored. A display command for operating state which is given from a sensor provided to the control system is indicated to the part 2 from an incidation input part 3. Thus the read operating state is displayed at a display part 4 consisting of pilot lamps such as light emitting diodes, etc. These lamps are arrayed n multiple stages and multiple strings. Then a prescribed display pattern is displayed with combinations of lighting of these pilot lamps.

Description

[Detailed Description of the Invention] The present invention is a display device that displays the operating status of a control system, and more specifically, a control unit equipped with a microprocessor stores and controls a display pattern, and displays a light emitting diode, lamp, etc. A display device VC of a control system that displays a predetermined display pattern from VC by combining the above-mentioned indicator lights according to the situation VC, such as the occurrence of an abnormality in operation, in a display unit consisting of a multi-stage, multi-row 1C salmon array of lights. related.

B. Prior Art Conventionally, a factory FC control system equipped with VC is equipped with the following equipment M7 for constantly monitoring the operating status of VC and displaying the details when an abnormality occurs. The operation panel and 1i14 control panel VC in the above control system include those with integrated structure and those with independent VC for each, but the VC on the panel is based on the operating status of the above-mentioned oil control system. For example, a display part is provided to display the contents of the operation, the occurrence of an abnormality, etc. This type of display part has carvings on the surface of the operation and control panel for each of the various display contents of the above-mentioned operating status, and also has lamps, etc. An indicator light was placed below the bacteria on the panel, and if an abnormality occurred, for example, an indicator light with the corresponding display content would light up, allowing the operator to visually confirm the display content. When the above-mentioned display is displayed on the display section, the operator performs an operation such as pressing a predetermined button to take appropriate action in response to the occurrence of the abnormality.

However, in the display using the above-mentioned operation and control panel, the display contents are fixed as they were at the time of manufacturing the display, so it is difficult to change or add display contents. Engraving is also very time-consuming, and the internal wiring is also complicated, making the structure of the device itself large-scale. Furthermore, as mentioned above, it is necessary to provide a display section with various display contents on the surface of the operation and control panel, and the size of characters etc. of each display contents is also restricted.
It was extremely difficult for an operator to visually check the displayed content from a location far from the location where the cup was installed. Furthermore, when an operational abnormality occurs in a normal control system, a combination of several types of display contents is often displayed, and the processing method for the display contents is not displayed. It is time-consuming and requires a skilled person to accurately handle the display, and the number of operators is often limited.

OBJECTS OF THE INVENTION The purpose of the present invention is to monitor the operating status of a control system, enable workers to quickly and accurately respond to the operating status, and to easily check the displayed contents even from a distance. It is possible to provide between display bags.

1. Effects of the Invention According to the present invention, 1 indicator lights such as light emitting diodes or lamps are arranged in multiple stages and in multiple rows and C alignments.4. Since the display is displayed by combining the lights on and off, it is possible to easily increase the size of one display section, and even a worker located far from the display section can easily visually check the displayed contents. . In addition, since the control unit uses a microprocessor, it is possible to display the operating status of the control system in a targeted manner without being tied to the displayed content.
, When an abnormality occurs, it is possible to display a countermeasure method, and even an inexperienced worker can quickly and easily deal with the problem. Furthermore, even if a large number of display contents are required, by storing the display pattern from the reading section, the overall structure of the device can be made much more compact compared to conventional devices. Even if the contents are different, the display contents can be easily changed and determined.
