Abstract
The utility model relates to a lighting controller, and particularly relates to an intelligent lighting controller comprising a DC power supply circuit, an MCU unit circuit, a CAN bus circuit, a current detection D/A conversion circuit, a standby battery circuit, a drive circuit, a buzzer circuit, an LED state indication circuit and a magnetic latching relay operation circuit. A CAN communication protocol bus is adopted by the intelligent lighting controller so that multiple control units can be controlled in a centralized way. Compared with common 485 communication, reliability, flexibly and real-time performance are enhanced. Connection of a relay can be controlled by a magnetic latching relay only by using one pulse so that large amount of power consumption is saved, and thus the intelligent lighting controller is safe and reliable and suitable for wide popularization and application.
