Description

Power Supply Maintenance Apparatus Having Electric Accident Prevention Structure

The present invention relates to a power supply maintenance device, and more particularly, to a power supply maintenance device including a configuration that can fundamentally block the occurrence of an electrical accident due to the interruption of electricity supply by being applied to equipment and units requiring constant power supply. will be.

Conventional uninterruptible power supply is installed in equipment that requires real-time power supply, and when a power outage occurs due to power supply failure due to natural disasters such as earthquakes and typhoons as well as damage to power supply facilities, it immediately supplies the same power as commercial power to the server. The quality of related services is being improved by enabling continuous service provision by preventing computer data loss.

In particular, R&D and product provision are being made to have high capacity and high output for the management of important core facilities such as lighting in aviation and ports.

In other words, the uninterruptible power supply is being developed to provide a high-capacity, high-efficiency, high-output inverter for long-time power failures of modern equipment, and a battery capable of storing large amounts of electricity. there is a big change.

Such a high-capacity, high-output uninterruptible power supply is suitable for relatively large facilities, and is not suitable for general life, small businesses, hospitals, facilities for the disabled and the elderly. It is necessary to develop a power supply device with power.

In particular, in case of power outage, it is necessary to use a small capacity for convenient use for hospitals, the elderly living alone or the disabled, or to require a safe electricity supply in a situation identification system, electric power outlet, communication area, and places with a lot of flammable substances, or There are various disadvantages such as the need to use an expensive power supply because the internal structure cannot be changed.

For example, if a power outage occurs in a storage warehouse without regular residents or in a shopping mall during the early morning hours, the quality of live fish or products occurs, which causes great damage in many cases. If it becomes a problem in the company, it is necessary to prepare for the damage because the responsibility is entirely transferred to the business owner and the building owner.

In addition, in the case of a small hospital or clinic-level hospital, if a power outage occurs during the operation, even the life of the patient may be at risk. Also, the need for an uninterruptible power supply is large, but there is a problem in that it is difficult to provide easily due to the high cost problem.

In the uninterruptible power supply using a lithium polymer battery of Korea Patent No. 10-1207142 (registration on November 26, 2012, see FIG. 1), a lithium polymer battery is used as a battery of an uninterruptible power supply (UPS) instead of a lead battery. Thus, miniaturization and weight reduction are possible, but there are problems with the risk of explosion and high cost of lithium polymer batteries.

The portable hybrid power supply device and method of Korean Patent No. 10-1163563 (registered on July 2, 2012) uses a hydrogen fuel cell to charge a secondary battery to supply power, and has the advantage of being eco-friendly and noiseless. Since it has a small capacity output, it is suitable for small devices such as mobile electronic devices and is not suitable for large capacity output.

The power supply device of Korean Patent Laid-Open Patent No. 10-2010-0002622 (published on Jan. 7, 2010) and a portable electronic device having the same apply a cartridge-type battery. It is suitable for small-capacity portable electronic devices that supply power regardless of power outage.

The 3-phase high-power UPS of Korean Patent Laid-Open No. 10-2009-0119978 (published on November 23, 2009) is used in factories that generate loads of 100KW or more, large-capacity pulp, and emergency lighting equipment such as airports. Not suitable for the general public, difficult to manage, and not easy to carry

Accordingly, there is a need for a technique capable of solving the above-mentioned problems according to the prior art.

In addition to a warning alarm to the external monitoring unit 171 and the internal monitoring unit 167, a separate pop-up alarm is provided so that the administrator can recognize that the corresponding route alarm has been confirmed, and the external monitoring unit 171 is provided to the administrator. Alternatively, it is preferable to display a warning alarm through a terminal or the like that is in direct possession rather than the internal monitoring unit 167, and the main control unit 170 is also connected to an externally connected fire station, etc. It is desirable to inform the level of occurrence so that a response can be made.

In addition, it is preferable that the main control unit 170 of the electric fire step-by-step monitoring system according to an embodiment of the present invention stops real-time monitoring of the fire monitoring module 100 at preset intervals and performs a self-diagnosis mode. .

In other words, as described above, since the malfunction of the main controller 170 causes great damage, in order to prevent this in advance, it is recommended to perform the 'self-diagnosis mode' at regular intervals according to the settings of the administrator (user, operator, etc.). desirable.

For this purpose, through a separate self-diagnosis sub-module provided in the fire monitoring unit 160, it is possible to diagnose whether each sensor of the fire monitoring unit 160 is normal, and accordingly, it is possible to determine whether or not to transmit/receive a normal sensing value. can be checked

The self-diagnosis sub-module preferably includes a heat generator, a high frequency generator, an arc generator, a light emitting device, and the like.

When performing the self-diagnosis mode, the main control unit 170 controls the operation of the self-diagnosis sub-module to create a virtual electric fire occurrence situation and diagnoses whether each sensor of the fire monitoring unit 160 is normal, It is preferable that the main control unit 170 accurately analyzes this to determine whether a control signal capable of performing an appropriate response is generated by making a diagnosis suitable for each situation.

Of course, it is desirable to stop real-time monitoring while performing the self-diagnosis mode.

As such, the electric fire step-by-step monitoring system according to an embodiment of the present invention can comprehensively diagnose the sensed values transmitted from a plurality of sensors, and can relatively accurately determine the current state of the housing body, and Each step can be set differently, so there is an advantage in minimizing the damage caused by the interruption of the electricity supply.
