Title:
MULTI-LAMP SYNCHRONOUS CONTROL METHOD, SINGLE CHIP MICROCOMPUTER AND MULTI-LAMP CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/104172
Kind Code:
A1
Abstract:
The present invention relates to a multi-lamp synchronous control method for synchronously controlling a plurality of lamps. The method comprises: a single chip microcomputer detecting whether a lamp is powered down; if the single chip microcomputer detects that the lamp is powered down, starting a timer inside the single chip microcomputer to perform timing; the single chip microcomputer determining whether the timer reaches a preset time when the lamp is powered on again; if the lamp is powered on before the timer reaches the preset time, the lamp entering the next working mode; and if the lamp is powered on after the timer reaches the preset time, the lamp entering the working mode of when same was last powered down. In the present invention, the time to start a timer to accurately control a lamp to switch working states after a CP pin of a single chip microcomputer detects that a mains supply signal is disconnected is prolonged by means of software sub-control, so that when a panel switch controls a plurality of lamps, all the lamps can enter the same working mode at the same time, thereby ensuring the working consistency of the lamps.
