The embodiment system firstly sets a counter (integer) of a person with an initial value of 0; since there is a case where a plurality of persons pass through the authentication in sequence, an optimum time interval t for passing through the authentication is setHuman being. When an entrance guard controller installed in an office monitors that a person passes through the office under authentication, the count is added with 1; and when the person is detected to pass out of the office, the count is reduced by 1. The system will wait for the optimum time interval tHuman beingIf people continue to enter and exit the office within the optimal time interval, the people counter accumulates the number of people; if no person enters or exits the office in the waiting optimal time interval, the number of the person flowing is the final accumulated value, and the energy generated by the flowing person in unit time is calculated to be count multiplied by QHuman beingThen, reset count to 0, and return the calculated energy to the air conditioning control module, where QHuman beingThe energy emitted to the human body in the unit time is the energy.

Specifically, the power of each type of office equipment may be stored in advance in the system of the embodiment; the system of the embodiment can monitor the starting and stopping states of office equipment through the network by the external equipment starting and stopping module, and when the starting and stopping of the equipment are monitored, the power of the equipment is obtained. Since the working time and the working time are the centralized time for intensively turning on and off the office equipment, in order to reduce the overhigh frequency of the control air conditioner, the system of the embodiment sets the equipment power number power with the initial value of 0 and sets the optimal start-stop time interval tIs provided with. The equipment start-stop module monitors that equipment is started, obtains the power of the type of equipment, power accumulates the power of the equipment, when the equipment is stopped, the power of the type of equipment is obtained, the power accumulates and reduces the power of the equipment, the optimal time interval is waited, and the time interval exceeds tIs provided withAnd starting and stopping the equipment, wherein the accumulated value of the power is the energy generated by the final equipment.
