Description

technical field [0001] The intelligent lighting control system of the invention belongs to the technical field of intelligent lighting control equipment. Background technique [0002] In the current lighting control device, when the heavy equipment under the same transformer or the same line is short-circuited or the power is switched, the power supply is very likely to generate and output surge voltage or surge current. This instantaneous pulse energy will impact the control circuit. Reduce the working life of electrical equipment, and burn electronic equipment in severe cases; on the other hand, in traditional lighting control circuits, transistors are used to directly drive the relay coil on the lamp circuit, and the reverse pulse voltage will be generated when the coil on the lamp circuit discharges Shock the transistor, reduce the service life of the transistor, or even break it down, making the circuit control invalid. At the same time, the signal input and output term...

Problems solved by technology

[0002] In the currently used lighting control device, when the heavy equipment under the same transformer or the same line is short-circuited or the power is switched, the power supply is very easy to generate and output surge voltage or surge current. This instantaneous pulse energy will impact the control circuit. Reduce the working life of electrical equipment, and burn the electronic equipment in serious cases; on the other hand, the traditional lighting control circuit uses transistors to directly drive the relay coil on the lamp circuit, and the reverse pulse voltage will be generated when the coil on the lamp circuit discharges Shock the transistor, reduce the service life of the transistor, or even break it down, making the circuit control invalid. At the same time, the signal input and output terminals of the single-chip microcomputer will also be impacted by the pulse voltage due to the damage of the transistor, which will damage the single-chip microcomputer chip, which may cause the single-chip microcomputer to reset and crash. , flying or control errors and other issues
