The invention discloses a method and device for reducing power consumption of an object detection system and a medium, and relates to the technical field of sensors. The scheme is applied to an object detection sensor connected with a functional module. According to the scheme, the correlation between the pulse signal number and the pulse time width and the error detection probability and the current consumption of the object detection sensor is considered; based on a first current consumption value in a starting state of an object detection sensor and a second current consumption value in an operation process of a function module, a pulse signal number and a pulse time width of an irradiation light driving signal are reasonably set. The irradiation light driving signal can uniformly meet the requirements of accurately detecting the object and reducing the power consumption of the object detection system, so that the waste of electric energy of the whole object detection system caused by false detection of th
