JPH02142329A - Domestic power interruption backup system - Google Patents

Abstract

PURPOSE:To facilitate backup by leading DC power produced through automatic starting of the engine of an automobile parked in a garage into the house through a cable and a connector upon interruption of household power, and subjecting the DC power to DC/AC conversion through an inverter. CONSTITUTION:A household power interruption monitor 9, a DC/AC inverter 11 and an automobile controller 10 are arranged in a house. Connector 5 of an automobile 1 is connected through a cable 6 with the automobile controller 10. Upon detection of household power interruption through the monitor 9, engine 3 of the automobile 1 put in a garage is started automatically through the automatic controller 10 and DC output of a generator 4 is fed through the connector 5, the cable 6 and the automobile controller 10 to the DC/AC inverter 11 where it is converted into AC power and distributed to household machinery 12. By such arrangement, a backup device can be provided at a low cost.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a home power outage backup system that realizes power supply during power outages in ordinary homes.

[Conventional technology]

Conventionally, this type of household power backup system during a power outage can be realized using a general-purpose generator, but even today there are very few homes equipped with a private power generator or storage battery. However, in recent years ISDN
With the advent of practical use, in-home communication methods are becoming more sophisticated, and it is difficult to achieve sufficient functionality by simply receiving power from the central telephone office as before, and for this reason, it is difficult to achieve sufficient functionality during power outages. Securing emergency power has become an important issue. On the other hand, considering Japan's housing situation, costs, etc., there is an urgent need to secure an economical backup power supply system that does not take up much space.

[Problem to be solved by the invention]

According to the above-described conventional system, it is necessary to prepare a dedicated generator to have a backup power source in case of a power outage, or to prepare a backup battery in advance. That is, such a method has drawbacks such as the need for an expensive generator and the need to prepare a special location for installing the generator or battery. Furthermore, in many cases, small-sized conventional generators cannot be started automatically, and must be started manually or must be equipped with such a function. Moreover, the daily maintenance of these generators or batteries has the disadvantage that it is a very troublesome task for ordinary households.

SUMMARY OF THE INVENTION An object of the present invention is to provide a household power outage backup system that eliminates such drawbacks and backs up a power supply for power outages at a relatively low cost.

[Means to solve the problem]

The home power outage backup system of the present invention includes a power outage monitoring device that detects a power outage in the house, and a power outage monitoring device that controls the startup of an engine installed in an external vehicle in response to activation from the monitoring device. an inverter circuit that is connected to the control device and the power outage monitoring device and converts power supplied from the vehicle from direct current to alternating current; and an inverter circuit that receives an activation signal from the vehicle control device and performs activation. an engine starting device that automatically starts the engine when a signal is received; and means for supplying electric power generated by the engine and a generator mounted on the vehicle to the outside of the vehicle via a cable and a connector. and is configured to provide power backup in the event of a power outage.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a power outage backup system for explaining one embodiment of the present invention.

As shown in FIG. 1, this embodiment is composed of an in-house device and a vehicle-mounted device, and the vehicle 1 includes a starter device 2 for an on-board engine 3, an on-vehicle generator 4 driven by the engine 3, It is equipped with a power supply connector 5 for supplying the power generated by the generator 4 into the house, and is connected to the house by a power cable from a pole-mounted transformer 8 on a utility pole 7.
In-home power outage monitoring device 9 that monitors power outages and this monitoring bag W9
The vehicle control device 10 is connected to a monitoring device 9 and a vehicle control device 10 that performs control to start the engine starting device 2 of the vehicle 1 based on power outage instruction information from the vehicle 1. It is equipped with a DC/AC conversion circuit 11 that receives power and converts it into AC power, and connects the car 1 with a power cable 6 and supplies the generated power to equipment in the house that requires emergency power during a power outage. It is also possible to back up the home equipment 12.

In such a power outage backup system, the power outage monitoring device 9 monitors power and, when detecting a power outage, notifies the vehicle control device 10 of this. When the vehicle control device 10 receives this notification, it sends an engine start command to the vehicle 1. On the automobile 1 side, an engine starting device 2 receives this starting command and starts the engine 3. The engine 3 is a generator 4 installed to supply electric power to the car.
The generator 4 converts the driving force of the engine 3 into electric power. The power generated thereby is supplied to the emergency power line in the house via the connector 5 and the cable 6. Incidentally, the starting bag W2 is designed to simultaneously control the output according to the engine load.

〔Effect of the invention〕

As explained above, the home power outage backup system of the present invention uses an on-board generator installed in a car as emergency power for home use, so it can be used anywhere without installing large-scale equipment in the home. This has the advantage that a reliable backup power source can be secured at a relatively low cost.
