Intelligent electrical controller

Abstract

The invention discloses an intelligent electrical controller comprising an input interface, a communication interface, a microprocessor, a drive unit, an output unit and a low-voltage power supply. The input interface is used for being externally connected with an input unit, and transmitting a control signal to the microprocessor; the communication interface is connected with the microprocessor to realize the communication between the microprocessor and the outside; the drive unit is controlled by the microprocessor to send the control signal to the output unit; the low-voltage power supply supplies power for a low-voltage element of the intelligent electrical controller, the output unit comprises a magnetic latching relay, and the drive unit comprises a relay drive unit; and the microprocessor outputs the control signal to the relay drive unit which sends a pulse control signal to the magnetic latching relay so as to control the opening and closing of a magnetic latching relay contact. The magnetic latching relay can still maintain the original state after power failure, can not change the state even if power failure occurs or general interference from the outside appears, and can normally work in the original state once power is restored, 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 thyristor drive circuit in the drive circuit, so 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. Changes in work or working status will bring uneasiness ...

AI Technical Summary

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.
