The current / voltage sensor 13 senses the current and voltage being used and converts it to a value suitable for input to the A / D converter 14, and the current and voltage modified to the appropriate value in the current / voltage sensor 13. The value is input to the A / D converter 14, and the A / D converter 14 converts it into a digital signal to measure the amount of power in real time. The A / D converter 14 uses a high-speed A / D converter because the amount of power must be measured in real time. For example, the A / D converter 14 processes data by performing A / D conversion at high speed every 1.38 ms.

The clock generation circuit 15 generates a system reference clock and applies it to the CPU 11 to set the system reference clock of the CPU 11.

That is, the CPU 21 processes data transmitted from the post 3 to the power management computer 2 in association with an FDMC ID, an amount of power for one hour and a total accumulated power, and an air conditioner control status flag. In addition, the post 3 processes the data received from the power management computer 2 in relation to the date and time of one hour, the FDMC ID and power amount initial value, the air conditioner control command, and the LCD display message.

Further, the CPU 21 processes data transmitted from the post 3 to the FDMC 6 in relation to the FDMC ID and power amount initial value, the date and time of one hour interval, the air conditioner control command, and the LCD display message. Further, the post 3 receives data received from the FDMC 6 in relation to the FDMC ID, the instantaneous power amount sampling value, the accumulated power amount, the air conditioner control state (including 1 bit of the air conditioner control switch flag), and the message response. Will be processed.

The RAM 22 stores data transmitted from the RF module 4. That is, the RAM 22 stores data related to a date and time, a total accumulated power amount for each FDMC ID, and an air conditioner control state.

The power supply and reset circuit 23 converts an AC voltage applied to the post 3 into a DC 5V and applies it to each component constituting the post 3 and resets it to an initial state. to be.

On the other hand, the post 3 is directly connected to the LAN via the 10Base-T LAN module 24, and is connected to the power management computer 2 via this LAN. If the LAN is not installed, the modem can be connected to the Internet by using a PPP (Point to Point Protocol) connection.

In addition, the RS-232C serial communication circuit 25 is for amplifying a signal from the RF module 4 for communication.

On the other hand, the RF module 4 is for wireless communication with the RF module 5 of the FDMC 6 side, the configuration and function is the same as the RF module 5 of the FDMC 6 side described above.

The power management computer 2 receives the remote air conditioner control signal and the text message transmitted from the Internet provider 1 for the electricity supplier and transmits the text message to the FDMC 6 of each home via the post 3.

In addition, various graphic displays and reports required for power operation are output using power amount data stored in the hard disk for each time zone. As a result, the network within the apartment complex is organized and management tasks are automated.

The main functions of the power management computer 2 in this regard are as follows.

First of all, the power consumption of the customers collected by the posts 3 is collected at regular intervals to construct a database, and various reports necessary for power operation are displayed using the power amount data stored in the database and a report is output.

In addition, it performs the role of a data server that transmits the power consumption of the customers to the server of the electricity supplier at regular intervals or when there is a demand from the electricity supplier.

In addition, by receiving the received remote air conditioner control signal and text message via the post (3) to the FDMC (6) of each home, and serves to synchronize the current time of each post (3) post (3) Serves as a server for.

It also initializes the strategic amount of a particular consumer.

On the other hand, the power management computer 2 constitutes a database by itself, and has the following functions.

That is, it stores the strategic amount of each customer every hour, and stores the electricity amount of each customer per month into daytime / evening / midnight / total and the power amount of each apartment in the daily and monthly apartments and the whole apartment in daytime / evening / nighttime / Store in total.

In addition, the event file includes a time when the post 3 is scanned and a scan result (time when the data has been uploaded or whether an error has occurred), a time when the data is requested from the electricity supplier server, and a time when all the data is transmitted, and a password change or system setting. Changes are saved.

On the other hand, the power management computer 2 is largely implemented in the following four processes.

1) SCAN

It is a process of scanning each post 3 at regular intervals, and reading and storing them in D / B.

2) user interface (UI)

The UI process provides four functions for power management.

Setup: Set password and select server for electricity provider.

3) MON

It is a process of monitoring the status of each post 3 through PING at regular intervals.

4) UPLOAD

The process of sending data to the provider server at the request of the provider server, or at regular intervals.

The data stored in the power management computer 2 performing the above function is directly transmitted to the Internet provider 1 for the electricity supplier through the Internet communication network, and the electricity supplier utilizing this data is associated with load distribution and electricity supply. The policy can be operated efficiently.

As described above, according to the present invention, it is possible to automate the entire process from meter reading to billing and collection and control of demand power by installing FDMC and using automatic weighing information communication using the Internet.

In particular, by adding up the electricity charges by counting the amount of power used at peak loads by time period, it is possible to induce voluntary distribution of loads, and if necessary, to control home or commercial air conditioners according to a separate agreement between electric users and suppliers. do.

Therefore, it is possible to reduce waste of national resources by remarkably reserve power by arbitrarily adjusting peak power and saving power consumption, maximizing energy efficiency and inducing load distribution.
