Abstract

The invention relates to a delay and instant start-stop control circuit of a power supply, which comprises an instant power-off circuit (1), a power-on excitation circuit (2), a power supply control circuit (3) and a delay power-off circuit (4), and is characterized in that the instant power-off circuit (1) is connected with one end of the delay power-off circuit (4) through the power supply control circuit (3); the instant power-off circuit (1) is connected with the other end of the time-delay power-off circuit (4) through the power-on excitation circuit (2). Compared with the prior art, themethod has the advantages that all parameters are convenient to adjust, and the triggering condition is simple.

Description

technical field [0001] The invention relates to the field of circuit control, in particular to a power supply delay and instant start-stop control circuit. Background technique [0002] When the equipment is in use, there will be two situations in which it is in the drone room and there are frequent people walking around. When in the unmanned room, the equipment needs to be able to be powered off by remote control. When there are many people, it is necessary to prevent the equipment from being powered off by misoperation. Therefore, the equipment needs to have two designs of immediate power-off and delayed power-off. [0003] At the same time, after the device is powered off, it must also have the function of restarting the device through the power button on the device. Most of the current existing circuits do not have the functions of both instant power-off and delayed power-off. And restarting the device requires restarting the main power supply. Contents of the inve...
