Equipment control method, control system and equipment

The invention provides a device control method, a control system and a device. A wearable device detects illumination intensity information in an environment through at least one ambient light sensor; the wearable device sends illumination intensity information to the target device, and the illumination intensity information is used for determining a state parameter in the operation process of the target device or is used for determining a state parameter in the operation process of at least one intelligent device controlled by the target device. Based on the device control method, the state parameter of the target device is determined according to the illumination intensity information detected by the wearable device, and the illumination intensity information detected by the wearable device can reflect the real illumination intensity of the environment where the user is located to the maximum extent, so that the user can control the target device based on the illumination intensity of the environment where
