Embodiment Construction

[0036] The specific implementation manners of the present application will be further described in detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0037] First of all, some nouns involved in this application are introduced:

[0038] A negative temperature coefficient (Negative Temperature Coefficient, NTC) temperature sensor generally refers to semiconductor materials or components with a large negative temperature coefficient. It works on the principle that the resistance value drops rapidly as the temperature rises.

[0039] External interrupt is an internal mechanism for the microcontroller to process external events in real time. When some external event occurs, the interrupt system of the single-chip microcomputer will force the CPU to suspend the program being executed and turn to process the interrupt event; after the interrupt...

Abstract

The invention relates to an equipment control method and device and a storage medium, and belongs to the technical field of electronics. The method comprises the steps of: receiving starting signals of a target device; obtaining compensation duration, wherein the compensation duration is used for offsetting the delay of a voltage zero crossing point detected by a voltage zero crossing point detection assembly; and when a zero crossing point signal is received, controlling a specified device in the target equipment to be turned on or turned off after the compensation duration, wherein the zerocrossing point signal is a signal sent by the voltage zero crossing point detection assembly when detecting a voltage zero crossing point. The problems that the heating device is easy to damage and the service life of target equipment is shortened when the heating device is controlled to be started at a position far away from a voltage zero-crossing point can be solved; because the actual voltagezero-crossing point can be determined, the specified device is controlled to be turned on or off at the actual voltage zero-crossing point, so that no impact current is generated to damage the specified device; and meanwhile, the precision of controlling the specified device can be improved, and the interference of opening and closing of the specified device on other equipment is reduced.

Description

technical field [0001] The present application relates to a device control method, device and storage medium, and belongs to the field of electronic technology. Background technique [0002] Electronic devices such as household appliances are usually powered by mains voltage. The mains voltage is usually alternating current. Taking the AC as a sine wave as an example, if the sine wave is used to control the heating element (such as the heating wire) in the hair dryer to work, then the heating element is controlled to turn on at a position far from the zero point of the sine wave, which will have an impact on the heating element Current, once the surge current is too large, the heating device will be damaged. Contents of the invention [0003] The present application provides a device control method, device and storage medium, which can solve the problem of easily damaging the heating device and reducing the service life of the target device when the specified device is c...
