PROBLEM TO BE SOLVED: To solve the problem that for the conventional midnight power equipment wire-connection, a time switch, a midnight watthour meter and the like are needed, which drives up costs. SOLUTION: The midnight power equipment comprises transceivers 21, 22, a data storage unit 24, and a power consumption arithmetic unit. Thus, an electric energy of every day is calculated by the arithmetic unit, integrated and stored in the storage unit 24. The energy of a certain period (one month or the like) stored in the storage unit is transmitted to a host computer 50 of a power company via a transmitter 22 when a transmitting command of the energy is delivered from the computer 50 of the company. Further, the using time zone of the equipment is controlled by receiving a command of allowing/inhibiting the operation of the equipment to be transmitted from the computer 50 of the company. |
