Dry burning prevention method, device and system, electronic equipment and storage medium

The invention is suitable for the technical field of electronic circuits, and provides an anti-dry-burning method, device and system, electronic equipment and a storage medium. The method comprises the following steps: acquiring a voltage signal applied to a heating load by a constant power module; calculating the duration of the voltage signal in a control period; wherein the starting moment of the control period is the moment when the rising edge of the voltage signal is obtained; according to the duration time and first preset time, whether the heating load is subjected to dry burning or not is determined; and when dry burning of the heating load is determined, a stop signal is sent to the constant power module, so that the constant power module stops heating the heating load. According to the invention, whether the heating load is dry-burnt can be judged by measuring the duration of the voltage signal applied to the heating load by the constant power module, which is easier than measuring other analog qua
