摘要： PURPOSE:To improve the monitoring function by displaying various messages and measured quantities on a dot LED display unit in the free space of the graphic panel. CONSTITUTION:If a fault occurs on a field board 14, the program of an IC memory card 18 operates to send display commands to a dot LED display unit controller 12 through a serial transmission cable 19, illumination colors of the dot LED chip 6 of the graphic part of the dot LED display unit 2 change, and a message is displayed in a message display area 7. As an example of the message in the case of an electric power system fault, etc., fault contents and a processing method are displayed. This is an example of the water level display of a water tank. For a digital display of electric energy, a measurement command is sent from a console panel 3 and then the electric energy is displayed as shown in a figure. This invention is constituted as mentioned above, so the messages and measured quantities can be displayed on the dot LED display unit, so the monitoring function is improved.

摘要： PURPOSE:To standardize a display part and to eliminate the need to design it according to the facilities at an installation place at each time by combining a dot LED display device and a symbol plate in one body. CONSTITUTION:A transparent plastic plate is stuck on the surface of the dot LED display device and the symbol plate where symbols of patterns and marks are printed is superposed on the transparent plastic plate to obtain the integrat ed display device. In this case, the dot LED display device 2 is usable for graphic display and the symbol plate 5 and display software are only generated according to the facilities at the installation place to complete the design. Conse quently, the display part is standardized and the need to design all parts for the installation place facilities at each time is eliminated.

摘要： PURPOSE:To extremely save the energy without deteriorating the service to the users by assigning the parking sections in accordance with increase of parking cars and at the same time controlling both ventilation and illumination equipments interlocking with each other. CONSTITUTION:A parking room of a self-drive type parking lot is divided into sections Z1 - Z3 with the ventilation and illumination equipments prepared to each section. In a parking space the parking car sensors V1 - V3 are prepared for each car. A central supervisory panel SV is set in a central supervisory room. Thus a self-drive type parking lot is formed. The parking sections are assigned in accordance with increase of parking cars and at the same time both ventilation and illumination equipments are controlled interlocking with each other. In this control system, the ventilation and illumination equipments are kept inactive while the parking demand is kept reduced. Thus the electric power is not wasted. Furthermore the panel SV detects the number of parking cars and controls automatically the assignment of the parking sections. As a result, the load of an operator is never increased.
