Time of flight (TOF) technology is understood in a broad sense as a technology that further understands certain properties of ions or media by measuring the Time it takes for an object, particle, or wave to fly a certain distance in a fixed medium (both medium/distance/Time are known or measurable).

when human body information exists in the space, the light source emitter and the photoelectric depth detector measure the distance of the space and construct local space information;
the time-to-digital converter is used for carrying out iterative operation in the detection, identification and judgment processes of the time flight module and outputting an operation structure to the memory;
and the controller analyzes the data in the memory and outputs a control instruction to control the air conditioner to execute a function corresponding to the instruction.
9. An air conditioner employing the control method of the operation of the air conditioner as set forth in any one of claims 1 to 7 or the air conditioner control system as set forth in claim 8.
10. The air conditioner according to claim 9, wherein:
the control flow of the air conditioner in different functions comprises the following steps:
the time flight module firstly judges whether human body information exists in the space;
when the space has human body information, local space information is constructed by taking the spatial position coordinate value of the head of the human body as a central point, and a functional area is divided;
the time flight module further judges whether the human body has the action of triggering the behavior in the functional area;
when detecting that the limbs of the human body move in a functional area or the staying time of the limbs of the human body reaches a preset time period, judging that the human body has a triggering behavior;
the time flight module detects the area with human body triggering behavior to determine the area position information and obtains the corresponding function information through the position information so as to control the air conditioner to execute the corresponding function.
