Intelligent electrical controller

Abstract

The invention discloses an intelligent electrical controller comprising an input interface, a communication interface, a microprocessor, a drive unit, a power failure detecting unit, an energy storageunit, an output unit and a low-voltage power supply. The microprocessor outputs a control signal to a controlled silicon drive unit and temporarily stores control data, and the controlled silicon drive unit controls the output of a controlled silicon output unit; the power failure detecting unit is connected with a mains supply and sends a signal for storing the control data to the microprocessorwhen the mains supply fails; and the energy storage unit provides electric energy needed by the microprocessor for storing the temporarily stored control data when the mains supply fails. The microprocessor in the intelligent electrical controller can store the dimming state data of a dimming controller before power failure in an internal electrically erasable memory, and restore the dimming controller to the state before power failure by automatically reading out the data when being electrified next time, thus bringing convenience for users.

Description

[technical field] [0001] The invention relates to the field of intelligent lighting and low-voltage electrical control, in particular to an intelligent electrical controller. [Background technique] [0002] Traditional intelligent electrical controllers, including lighting controllers, curtain controllers, dimming controllers and scene controllers, etc., all of them have a defect that when encountering sudden interference, or after a power outage and then on, or a momentary power failure Electricity, or some parts of its own control circuit failure, the intelligent low-voltage electrical controller cannot work normally. This intelligent low-voltage electrical controller uses a conventional non-magnetic latching relay circuit or a thyristor drive circuit in the drive circuit. Once the power is lost or it is subject to external interference or some components in the circuit fail, the controller will not work normally or The working state changes, which brings uneasiness and i...

Problems solved by technology

When the load is working, the relay needs to consume power. For a huge lighting system, because the lighting controller needs many relays, in order to maintain the lighting system, the relay of the lighting controller will consume a lot of power.
