Centralized power supply comprehensive intelligent control system for supplying power for indoor lighting system

Abstract

The invention relates to a centralized power supply comprehensive intelligent control system for supplying power for an indoor lighting system, which comprises a voltage sensor, a backup alternating current power supply, a shift switch, an alternating current / direct current switching circuit, a backup alternating current / direct current switching circuit, a direct current / alternating current inverter circuit, a storage battery, the indoor lighting system, a monitoring module, a control module and a control terminal. According to the centralized power supply comprehensive intelligent control system for supplying power for the indoor lighting system, the storage battery is in a real-time online operation and serves as a supplement of normal power supply, thereby when outage occurs in mains power grid, the storage battery instantly serves as a main force to supply power. When the backup alternating current power supply comes into operation, the storage battery further serves as the supplement of emergency power supply so that a function of automatically and seamlessly switching to the backup alternating current power supply when the outage occurs in power grid can be guaranteed to be achieved.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a centralized power supply integrated intelligent control system for supplying power to an indoor lighting system. Background technique [0002] Generally, indoor lighting systems directly use the mains power grid as the power supply to provide the power demand required by all loads. When the power supply is abnormal (such as power failure, low or high voltage, and abnormal frequency, etc.) , it may happen that the load does not work or the load is damaged. [0003] The principle of the existing uninterruptible power supply (UPS) is: when the mains power grid supplies power normally, the uninterruptible power supply is in the state of charging, and if the mains power grid is abnormal, the uninterruptible power supply is transferred from the charging state to the discharging state to provide The power required by the load. [0004] The existing uninterruptible power supply gen...

AI Technical Summary

Problems solved by technology

[0004]The existing uninterruptible power supply generally supplies the emergency power needs of some important equipment, and does not have the function of professionally supplying lighting power. At that time, the surroundings will be plunged into darkness, and all light sources will disappear due to a power outage, so additional emergency lighting equipment must be equipped

[0005]The emergency lighting equipment can only provide moderate lighting for a short time, so that people can finish their work in a short period of time or guide asylum seekers to escape smoothly when encountering an emergency

This has caused great inconvenience to people's normal production and life.

Especially in places like hospitals, shopping malls, stations, etc., it will bring great losses and troubles
