Title:
INTELLIGENT LAMP CONTROL SYSTEM AND DETECTION CIRCUIT FOR TEMPORARY POWER-OFF SWITCH THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/206263
Kind Code:
A1
Abstract:
A detection circuit for a temporary power-off switch and an intelligent lamp control system. The detection circuit for a temporary power-off switch comprises: a rectifier and filter circuit, the input end of the rectifier and filter circuit being connected to an alternating current power supply by means of a temporary power-off switch, and the output end of the rectifier and filter circuit being connected to both the input end of a detection circuit and the input end of a DC-DC converter, and the rectifier and filter circuit being used for rectifying and filtering input alternating current to output a direct current bus voltage; the detection circuit, the output end of the detection circuit being connected to the first AD input end of a control circuit, and the detection circuit being used for sampling the direct current bus voltage to detect the on/off action of the temporary power-off switch so as to generate and output a temporary power-off detection signal to the control circuit; the DC-DC converter, the output end of the DC-DC converter being connected to the power supply end of the control circuit, and the DC-DC converter being used for supplying power to the control circuit; and the control circuit used for determining the on/off state of the temporary power-off switch according to the temporary power-off detection signal. According to the present application, the on/off state of the temporary power-off switch can be effectively determined, so as to control the working state of an electrical device.
