Thereby, the capacity of the auxiliary power source part 10 can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a display control device for a system including a device that operates only with commercial power and a device that operates with a power source other than commercial power.

BACKGROUND TECHNOLOGY In general, devices that operate on commercial power are connected to terminals in two systems, and in the event of a power outage, all operations are stopped, or
Countermeasures were taken, such as having a backup power source so that it would only operate for a predetermined period of time. In particular, in the case of a control panel that centrally controls a plurality of terminal devices, all displays are turned off in the event of a power outage, or only the fact that there is a power outage is displayed.

Alternatively, the configuration was such that normal operation was performed and normal display was performed during a predetermined backup period.

Problems to be Solved by the Invention However, in display control using such a conventional centralized control panel, a large amount of work is required to ensure that the terminal equipment, which normally operates on commercial power, operates in a specified manner even in the event of a power outage. It was equipped with a power supply that was blown out and displayed normally for a certain period of time.

In other words, the capacity of the auxiliary power supply had to be increased in order to guarantee the entire system or a portion thereof. especially,
For those with a clock display malfunction, there is a system that guarantees the operation of the clock only by displaying the display tube or LE.
A large amount of power was required to control the display of D, etc.

Kihatsu IE14 solves these conventional problems, and allows the central control unit to operate the remote control unit and display only for terminal devices that operate on power sources other than commercial power sources, and allows the auxiliary power source to be used. The present invention provides a centralized control device whose capacity is as small as possible.

Means for solving the problem of inconvenience A system comprising a central control device of the present invention, a device 1 that operates on a power source other than a commercial power source, and a device 2 that operates on a commercial power source. a central control unit having a remote control unit, a display 1.2 that indicates the operating status of each device, and a display control unit that controls the display; and a main power source that supplies power from a commercial power source to the central control unit. an auxiliary power supply section that supplies power for a predetermined time during a commercial power outage; a power supply switching section that switches between the main power supply section and the auxiliary power supply section; a power outage detection section that detects a power outage of the commercial power supply; and a display control section that stops the operation of the display device 2 when there is a power failure detection signal from the section.

Function: The central control device of the present invention detects a power outage of the commercial power source using the power outage detection unit, and turns on all indicators 2 indicating the operating status of the terminal device 2 that operates only with the commercial power source based on the signal. The display control section works to do this. That is, in the event of a power outage, the central control unit is backed up by an auxiliary power source and performs remote control and operation display of the terminal device 1 that operates on a power source other than the commercial power source. Therefore, during a power outage, all remote controls and displays on the terminal device side that do not operate are turned off, so the backup power capacity for the central control unit can be reduced.

Embodiment Below, a block diagram of a central control device according to an embodiment of the present invention is shown in FIG. 1. Terminal device 1 that operates on a power source other than commercial power supply 2. Terminal device 2 that operates only on commercial power supply
．． 3 is a remote control unit of the terminal device of 1.2 above, 4 and 5 are indicators 1 and 2.6 indicating the operating status of 1.2 are display control units for controlling 4 and 5, and 7 is the above-mentioned display control unit. 3.4.5
．． 11 is a centralized control section consisting of 6, 8 is a commercial power supply, 9 is a main power supply section that supplies power from the commercial power supply to the centralized control section, 1
0 is an auxiliary power supply unit. Reference numeral 11 denotes a power supply switching section for switching between the main power supply section 9 and the auxiliary power supply section 10, which has the function of connecting the auxiliary power supply side to the central control section and operating it effectively during a power outage.

12, a power outage detection section of the commercial power supply transmits the fact that there is a power outage to the display control section in the central control section, and the display control section stops the operation of the display 2.

FIG. 2 shows an embodiment of a specific system of the central control device of the present invention. , those having the same numbers as in FIG. 1 are components having the same functions. Reference numeral 13 denotes a gas cutoff device that generally corresponds to the terminal device 1, and its operation is guaranteed by a dry battery 14. Reference numeral 15 denotes a hot water heater which generally corresponds to the terminal device 2, and is supplied with power via the commercial power supply plug 16. has been done. 17 is a plug for supplying commercial power to the centralized control unit 7. The indicator 4 indicates the operating state of the terminal device 13 in the wood embodiment, and indicates whether gas is in use or gas is cut off. Gas cutoff device 13
Since it is operated by a dry cell battery 14, it is necessary to guarantee operation and its display for a predetermined period of time even during a power outage. The display 5 shows the operating state of the terminal device 15, and has a clock display function, a hot water supply side combustion state display function, and a heating side combustion state display function in the example. At the time of power outage, all the display devices 5 are turned off, and the power consumption of the central control unit is reduced.

FIG. 3 shows a schematic control flow within the centralized control section. 18
performs remote control (■) and controls the terminal device 1.

Reference numeral 19 denotes a portion that controls the display 1, which operates regardless of the presence or absence of a power outage. Reference numeral 20 denotes a determination unit for determining whether or not there is a power outage. If it is not a power outage, the process proceeds to 21.22 and performs remote control (2) for controlling the terminal device 2 and il control for the display 2. When the engine is stopped, the process branches to 23.24, and the remote control III executes a process to stop the terminal device 2, and the display 2 off section executes an operation to completely turn off the display 5.

Effects of the Invention As described above, the central control device of the present invention detects a power outage of the commercial power supply using a power outage detection section, and operates the second terminal device using only the commercial power supply based on the power outage signal from the detection section. This is a central control unit that has in the same part the first display of a first terminal device that operates using a power source other than a commercial power supply. The auxiliary power supply capacity can be made smaller. That is, it is possible to provide the centralized control section with the minimum required functions with the minimum bank amplifier power supply capacity.
