Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention supplies commercial power from a secondary battery when the commercial power is cut off.
The present invention relates to an uninterruptible power supply device that can be connected to an externally connected device via a communication port connected to a computer.

[0002]

2. Description of the Related Art Computers require certain operations when they are turned off. If the power is cut off without this operation, the state before the power is cut off cannot be restored, and various harmful effects occur. Unfortunately, the commercial power source that supplies power to the computer is
There may be a temporary power outage. An uninterruptible power supply is used to solve this problem. Uninterruptible power supply,
It incorporates a DC / AC converter that outputs alternating current equivalent to a commercial power source using a secondary battery as a power source, and a circuit that detects that the commercial power source is cut off. This uninterruptible power supply,
When it is connected to a computer power outlet and commercial power is cut off, it outputs the same alternating current as commercial power.

[0003]

Therefore, the power outlet of the computer can be connected to the uninterruptible power supply to prevent the harmful effects caused by the interruption of the commercial power supply. By the way, the computer has a hard disk and a CD-RO.
It is often used by connecting an externally connected device such as M or CD-R. These externally connected devices are connected to the computer via a communication port such as a USB port. This communication port has a signal line and a DC power supply line. Therefore, the computer can be used while supplying power to the externally connected device. However, the total power that can be supplied from a computer to externally connected devices is limited. For this reason, if a large number of externally connected devices are connected to the computer or externally connected devices with high power consumption are connected, normal operation cannot be achieved.

This problem can be solved by using an externally connected device having a built-in power supply circuit. This type of externally connected device does not need to supply power from a communication port such as a USB port because it has a built-in power supply circuit. Therefore, USB
The number of units connected to communication ports such as ports and power consumption are not limited. This type of externally connected device has a drawback that the manufacturing cost is high because it has a built-in power supply circuit. Further, this type of externally connected device is likely to cause a problem when it is used by connecting to a laptop computer.
This is because the laptop computer does not use the uninterruptible power supply because it has a built-in secondary battery. A laptop computer does not need to use an uninterruptible power supply because the power is not cut off by supplying power from a secondary battery even when commercial power is cut off.
However, an external connection device such as a hard disk having a built-in power supply circuit is also connected to the laptop computer. In particular, since a laptop computer does not have sufficient power supply capacity, it is preferable to connect an external connection device having a power supply circuit. However, when an externally connected device having a built-in power supply circuit is connected to a laptop computer and used, if the commercial power supply is cut off, the externally connected device may not operate.

The present invention was developed for the purpose of solving such drawbacks. An important object of the present invention is to provide an uninterruptible power supply device that can connect a large number of inexpensive externally connected devices that do not have a built-in power supply circuit and can operate both externally connected devices and a computer normally when commercial power is cut off. To provide. Another object of the present invention is to provide a structure that responds to a virus included in information from the outside when information is externally supplied to a connected device via an uninterruptible power supply. is there.

The control circuit 4 for converting the output of 1 into the AC of the commercial power supply voltage and outputting it to the power supply output terminal 8, the communication port 5 for the computer, the terminal adapter circuit 6 connected to the telephone line, and the commercial power supply are cut off. Even via a storage circuit 7 for storing external information, a mail search circuit 10 for automatically accessing a mail server to load a mail, a fingerprint identification device 11 for identifying a user's fingerprint, and a communication port 5. DC power supply output terminal 9 for supplying DC power to the connected electric device 17, wireless LAN circuit 12, and remote control circuit 13
A hacking prevention circuit 14 and a stabilizing circuit 15.

The secondary battery 1 is a rechargeable battery such as a nickel-hydrogen battery, a nickel-cadmium battery or a lithium ion secondary battery. The output voltage of the secondary battery 1 is adjusted by the number of serially connected batteries. The total output voltage of the plurality of secondary batteries 1 connected in series is set to 12 to 15V. However, it can be set lower or higher than this voltage. In particular, the device shown in the figure, which stabilizes the output voltage by the stabilizing circuit 15 and outputs it to the power supply line 16,
The output voltage of the secondary battery 1 can be increased and controlled to a constant voltage output. Secondary battery 1 having a voltage lower than the voltage of the power supply line 16
Is converted into an optimum voltage by a DC / DC converter and output.

The capacity of the secondary battery 1 is set so that the computer or the like connected to the communication port 5 can be normally terminated when the commercial power supply is cut off. Most computers can finish normally in about a minute. Therefore, the capacity of the secondary battery 1 is set to a capacity capable of driving the computer for 2 minutes or more, preferably 3 to 10 minutes.

The charging circuit 2 converts a commercial power source into a DC voltage that can charge the secondary battery 1. The charging circuit 2 also includes a circuit that prevents overcharge of the secondary battery 1. In order to realize this, the charging circuit 2 stops the charging when detecting the full charge of the secondary battery 1, or holds the secondary battery 1 at a predetermined voltage to perform floating charge, or alternatively When it is charged, trickle charge is applied to prevent deterioration of the battery. The charging circuit 2 also outputs electric power to the power supply line 16 when the commercial power supply is not shut off.

The DC / AC converter 3 converts the direct current of the secondary battery 1 into an alternating current. The output voltage and frequency of the DC / AC converter 3 are set to the commercial power supply voltage of each country. Japanese commercial power supply voltage is 100V, frequency is 50 or 60H
Therefore, the output voltage is AC100V and the frequency is 50.

When the commercial power source is cut off, the connection switch 18A is turned off and the connection switch 18B is turned on, contrary to the position shown in the figure, and the output of the secondary battery 1 is converted to the commercial power source AC by the DC / AC converter 3. It is converted and output to the power output terminal 8. Since the control circuit 4 shown in this figure does not need to operate the DC / AC converter 3 when the commercial power supply is not cut off, wasteful power consumption in this state can be reduced. However, although not shown, the uninterruptible power supply device of the present invention converts the direct current, which is the output of the charging circuit, into the alternating current of the commercial power source by the DC / AC converter and outputs it to the power source output terminal when the commercial power source is not cut off. You can also This uninterruptible power supply device is the same in that when the commercial power supply is cut off, the direct current of the secondary battery is converted to the alternating current of the commercial power supply by the DC / AC converter and output to the power output terminal.
