Abstract

PURPOSE:To reduce the capacity of a backup power unit by separating a power source into two systems to back up the minimum required part by the backup power unit. CONSTITUTION:The terminal controller 1 is separated to a non-backup part 2 for a unit system for which no backup is required i.e., whose inoperable state due to power failure, etc., can be permitted temporarily, and a backup part 3 for the system of a main control part, etc., for which the backup is required. In such a case, the power source 4 is divided into a part from which a power is supplied to the non-backup part 2 and a part from which it is supplied to the backup part 3, and power cables 5, 6 are drawn from them, respectively, and the power cable 5 on one side is directly connected to a commercial AC receptacle, and the power cable 6 on the other side to the commercial AC receptacle via the backup power unit 7. The non-backup part 2 is operated with the power source from the cable 5, and the backup part 3 with the one from the cable 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal controller, and more particularly to a terminal controller that operates from a commercial AC power source.

[0002]

2. Description of the Related Art A conventional terminal controller operated by an AC power source has only one power supply cable,
The power for the entire device was supplied by a single power supply.

[0003]

In this conventional terminal controller, if the backup power supply is not connected, the system will be completely down due to a power failure or the like. Further, connecting the backup power supply to the power supply cable requires a backup power supply having a large capacity capable of backing up the entire load of the terminal controller, which is a problem.

[0004]

SUMMARY OF THE INVENTION A terminal controller of the present invention comprises a non-backup section that does not require power backup, a backup section that requires power backup, and a backup power supply device that supplies power to the non-backup section. A first power source not provided and a second power source having a backup power supply device for supplying power to the backup unit
Power supply.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.

The inside of the terminal controller 1 does not need to be backed up, that is, the non-backup section 2 of the system of the unit which may be temporarily inoperable due to a power failure or the like, and the system of the main control section or the like which needs the backup. It is divided into the backup unit 3.

The power supply 4 is divided into a part for supplying electric power to the non-backup part 2 and a part for supplying electric power to the backup part 3, and one power supply cable 5 and 6 is output from each of them. 5 is directly connected to a commercial AC outlet, and the other power cable 6 is connected to a commercial AC outlet via a backup power supply 7.

The non-backup section 2 is operated by the power source supplied from the cable 5, and the backup section 3 is operated by the cable 6.
It operates by the power supplied from the power source.

[0010]

As described above, according to the present invention, the capacity of the backup power supply device can be reduced by dividing the power supply into two systems so that the minimum necessary part of the terminal controller is backed up by the backup power supply device. There is an effect that you can.

Claims (1)

[Claims] 1. A non-backup unit that does not require power source backup, a backup unit that requires power source backup, a first power source that does not include a backup power supply device that supplies power to the non-backup unit, and the backup unit. And a second power supply having a backup power supply for supplying power to the terminal controller.
