In Fig. 5, a data logger 2 is provided between the transformer means 43, 43 'and the load means 45, 45'. Specifically, a breaker (ACB) is installed on the line for supplying power from the transformer means (43) to the load means (45), one end of the breaker (ACB) for protecting the no-load power factor through a protective switch (MCCB) In addition to the condenser COND, the data logger 2 is connected through the transformer PT, and the other end of the current transformer CT for sensing the current supplied to the load means 45 is installed. The data logger 2 is connected to the current transformer CT.

Although FIG. 5 shows that two transformer means 43, 43 'and two load means 45, 45' are provided in parallel, more than that may be provided in parallel.

In addition, the data logger 2 is connected to the central control unit 1 and the load means 45 by a communication network, so that the data logger control unit 14 of the central control unit 1 is a program storage unit of the data logger unit 3. By controlling the execution of the program stored in 21, the power parameter control unit 24 controls and adjusts the parameters of the supply power.

The room control unit 3 is provided with a mode selecting means 47 so as to manually or automatically select a state control such as on / off or intensity control of light / heating electric / electronic devices. Although FIG. 5 shows that the supply power is applied to the room control unit 3 through the distribution panel 46, the load means 45 is configured as one room, and the temperature, illuminance, and human body sensor 31 are included in the room. By providing means for measuring the atmosphere in the room, such as a), the load means 45 can be simply configured as the room control unit 3.

Figure 6 is a flow chart for controlling the lighting fixture on / off in one embodiment of the present invention, first the human body sensor 31 detects the human body in the room (step S1).

In this step S1, the human body sensor 31 detects the human body existing in the room as an ultrasonic or infrared sensor, and the CPU 12 of the central controller 1 processes the detected information to determine whether a person is present in the room. It is determined (step S2).

If there is a person in the room at step S2, the process proceeds to step S3 and the illumination sensor 31 installed in the room checks the current illuminance in the room and provides the real time to the central control unit 1 in real time. If the illuminance in the room is equal to or less than the prescribed value compared to the illuminance previously set in the recording means of the recording means (step S4), the process proceeds to step S5 to turn on the luminaire so that the luminaire is turned on.

If there is no person in the room in step S2 or if the illuminance in the room is higher than the prescribed value in step S4, the process goes to step S6 to turn off the lighting fixture.

In addition, when the room control unit 3 alone is on / off control irrespective of the central control unit 1, the mode selection means installed in either or both of the central control unit 1 and the room control unit 3 When the on / off control of the luminaire of the room control unit 3 is selected by selection, and the detection signal of the human body sensor 31 is transmitted to the room control unit 3 in this state, the MPU of the room control unit 3 is selected.

Then, the temperature sensor 31 installed in the room checks the current temperature in the room in real time (step S12) and transmits it to the central control unit 1, and the measured temperature in this room and the recording means of the central control unit 1 are previously recorded. The set temperature is compared by the CPU to determine whether the temperature in the room is within the set range (step S13). If it is determined that the measured temperature is not within the set range, the process proceeds to step S14 and the central controller 1 transmits a control signal to the room controller 3. Accordingly, the air conditioning control means in the room controller 32 is operated so that the air conditioner performs the cooling or heating function so that the temperature in the room is adjusted within the set range.

Subsequently, the human body detecting sensor 31 detects the human body and checks the preset time set in the recording means of the central controller 1 (step S15) to determine whether or not a person exists in the room within the set time (S16). step). As a result of the determination, when there is a person in the room within the set time, steps S12 to S16 are executed sequentially.

Done.

In the above-mentioned temperature control of the room, the air conditioner which can be executed together with the cooling function and the heating function has been described as an example. However, in the case of an air conditioner or a heater that does not have both the cooling function and the heating function, the temperature in the room is controlled by controlling the air conditioner and the heater separately. Of course it can be adjusted.

Unlike this, the operation signal of the heater is transmitted to the communication port 33 of the room controller 32 by the central controller 1 through the communication port 11 at the set time recorded and recorded in the recording means of the central controller 1. In accordance with the transmission, the corresponding heater of the room controller 32 may be operated to be in an optimal state in which the atmosphere in the room is set in advance.

Although electric and electronic devices using power supplied from a power generation facility have been described so far, the present invention is not limited thereto, and various modifications can be made without departing from the spirit of the invention. For example, the present invention can be easily employed for the operation control of devices operated by other sources such as batteries, as well as devices supplied with operating power to electrical and electronic devices through power lines.

The present invention, which operates as described above, does not use an infrared remote controller, and automatically controls various electric and electronic devices such as an on / off state of an electric light or a heating device by using various sensors and wired / wireless communication networks, and is unnecessary when not needed. It is very economical and saves energy on a national level by not wasting power without having to automatically operate electric and electronic devices.

In addition, by automatically controlling various electrical and electronic equipment, users of electrical and electronic equipment can maximize the convenience of use, and automatically turn off the electrical and electronic equipment when there is no user in the room.
