Accordingly, the Ministry of Commerce, Industry and Energy has been promoting the <Waiting Power 1W Program> since 2005. If the achievement rate of 1W standby power of various electronic products reaches 80%, it expects to save enormous cost of 730 billion won annually. have.

Various power-saving technologies have been proposed to keep pace with such social trends. Examples of such technologies include, for example, attaching sensors to lighting equipment to automatically turn off lights when it is determined that no person exists in the space. For example, there is a method of centrally controlling the supply / blocking of power for each floor or office. And, it is true that these techniques can cause a certain power saving effect compared to the prior art.

1A is a schematic diagram of a network type power management system according to an exemplary embodiment of the present invention, and FIG. 1B is a schematic diagram of a network type power management system according to another exemplary embodiment of the present invention.

First, referring to FIG. 1A, it can be seen that the network type power management system according to an embodiment of the present invention includes a plurality of terminal capacitors 110, a power measuring unit 120, a controller 130, and the like. have.

The terminal capacitor 110 is connected to the electrical appliances to perform a function of supplying power to each electrical appliance. At this time, each terminal capacitor 110 may be assigned a unique identification ID (id), so that the control unit 130 is a terminal capacitor when a certain condition is met or a control signal is input by the administrator, etc. 110, it is possible to manage the supply / interruption of power.

That is, in the case of a large building having several floors and several offices for each floor, it is assumed that more than 10 terminal capacitors for power supply are provided only in one office, and the controller 130 controls the respective terminal capacitors. By being able to directly manage the supply / blocking of power to 110, as a result, it is possible to obtain the same effect as performing the direct power management for the individual electrical products.

In other words, when it is determined that the amount of power consumed by one terminal capacitor 110-1 is less than or equal to the standby power of the normal electrical appliance, the standby power of the electrical appliance is cut off by cutting off the power applied to the terminal capacitor 110-1. It can save the unnecessary energy consumed. In addition, when it is determined that there is a risk that the amount of power consumed from the other terminal capacitor (110-2) exceeds the rated capacity, etc., it is possible to prevent the overload, etc. by cutting off the power applied to the terminal capacitor (110-2). There is also an advantage. In this case, the supply / blocking of the direct power to each terminal capacitor 110 may be made by a switching device, etc., which is separately provided. However, the controller 130 may be provided at the front end or the rear end of the power measuring unit 120. It may be desirable to have a switching means that operates in response to a control signal transmitted from the apparatus. Therefore, although not separately mentioned, the signal line interconnecting the terminal capacitor 110, the power measuring unit 120, and the controller 130 may be a bus data line capable of supporting a TCP / IP scheme or the like. It would be nice to be done. However, it is obvious that the present invention is not necessarily limited thereto.

Here, each terminal capacitor 110 is a unit capacitor (for example, 110-) into which a plug of an electrical product can be inserted in consideration of various factors such as controllable power supply line and installation of the power measuring unit 120. 1-a, 110-1-b, etc.), or may be in the form of a combination of two to three unit capacitors (eg, 110-1 or 110-2).

Next, the power measuring unit 120 performs a function of measuring the amount of power consumed by each terminal capacitor 110 in real time and transmitting it to the control unit 130. In this case, data transmission between the power measurement unit 120 and the controller 130 may be performed by various communication methods of wired and wireless, and may be configured by a mixed use of wired and wireless.

1A illustrates a network type power management system according to an exemplary embodiment of the present invention configured by a wired communication network, FIG. 1B illustrates a network type power management system according to another exemplary embodiment of the present invention configured by a wireless communication network.

That is, the network type power management system according to another embodiment of the present invention as shown in FIG. 1B is configured such that power management of the terminal capacitor 110 by the controller 130 may be performed by various wireless communication methods. The case is shown. In other words, a separate wireless communication module 150 directly connected to the control unit 130 transmits a control signal for each terminal capacitor 110 by a wireless communication method. As such a wireless communication method applied to the embodiment of the present invention, there may be various methods such as Zigbee, zigbee, Bluetooth and RF or infrared communication. Preferably, the Zigbee method may be most suitable.

To this end, each terminal capacitor 110 is preferably provided with a wireless data transmission and reception antenna 125 corresponding to the corresponding communication method, the power supply / blocking switching of the power supply to the terminal capacitor 110 is the power measuring unit 120 Assuming that the antenna 125 is located on the power measurement unit 120 in the drawing (FIG. However, it is obvious that the present invention is not limited thereto.

There may be a plurality of wireless communication modules 150 connected to the controller 130. That is, the wireless communication module 150 is provided in unit areas such as floors or offices, and receives power consumption data for the terminal capacitor 110 existing in the corresponding area and controls each terminal capacitor 110. It is preferably configured to transmit a signal.

Therefore, it is preferable that the wireless data signal transmitted from the wireless communication module 150 includes an identification signal for each terminal condenser 110, and data processing between corresponding unit areas of the adjacent wireless communication module 150 is conventional. It may be possible to use a hand-off method or the like.

Such a network type power management system according to another embodiment of the present invention has the advantage that the complicated wiring and the like are unnecessary, resulting in the improvement of aesthetics of the interior, etc., short circuit, and short circuit prevention.

In consideration of various conditions such as a building or an office and installation costs, the network type power management system according to the present invention may have various configurations using a wired, wireless or wired / wireless hybrid scheme.

Here, the power measurement unit 120 provided in the network type power management system according to an embodiment of the present invention shown in Figures 1a and 1b can be modified in various forms, for example representatively FIG. It may have a configuration such as

FIG. 2 is a diagram illustrating an example of a configuration of a power measuring unit applied to a network type power management system according to an exemplary embodiment of the present invention shown in FIGS. 1A and 1B.

Referring to FIG. 2, the power measurement unit 120 included in the network type power management system according to an embodiment of the present invention includes a power meter 122, an amplifier 124, and an analog / digital converter (A / D converter, 126) and a controller (micro-controller unit, 128) and the like can be seen. However, the present invention is not necessarily limited thereto.

The controller 130 monitors power consumption data for each of the terminal capacitors 110 transmitted from the plurality of power measuring units 120 and manages power supply / blocking to the terminal capacitors 110.

That is, as a result of monitoring the data transmitted from the power measuring unit 120, when the amount of power consumed from any terminal capacitor is less than the standby power of the electrical appliance, it is possible to generate a cutoff control signal of the power supplied to the corresponding terminal capacitor, which terminal When the amount of power consumed from the capacitor is close to the rated capacity of the corresponding terminal capacitor, the supply / blocking management of the power supply to the terminal capacitor 110 is also generated by generating a control signal for shutting off the power to the terminal capacitor. Will be able to perform. In this case, it has been described above that the actual power supply / blocking switching to the terminal capacitor 110 may be performed by a switching element separately provided or a switching means provided in the front / rear end of the power measuring unit 120. .

In addition, when the power measurement unit 120 is applied to a wireless data communication network type power management system as shown in FIG. 1B, the power measurement unit 120 transmits power measurement data of the terminal capacitor 110 to the control unit 130 and the corresponding terminal from the control unit 130. A facility for wireless data communication such as an antenna 125 for receiving a control signal for the condenser 110 may be provided.

In this case, the data transmission between the power measuring unit 120 and the control unit 130 may be performed through a separate wireless communication module 150 provided in each unit zone.

Here, it is natural that a user or a manager or the like can command the power supply to the terminal capacitor 110 which is automatically supplied / blocked by the controller 130. However, even in this case, if there is a risk of a safety accident such as exceeding the rated capacity, it may be desirable to set the manual command not to be allowed.

The network type power management system according to the embodiment of the present invention may further include a database 140 for storing / managing data such as power usage for each terminal capacitor 110.

That is, since the database 140 is additionally provided, the network type power management system according to the embodiment of the present invention can store power usage data for each terminal capacitor 110 and make statistics of them. Not only can it plan / prepare the expansion of the entire electricity supply capacity, but it is also easy to grasp the leakage current, and thus, there is an advantage that it is possible to timely perform the maintenance and repair work accordingly.

Further, the power usage pattern analysis according to seasons, days of the week, and time for each terminal capacitor 110 can be performed, such that the supply / blocking schedule of power for each terminal capacitor 110 can be enabled. There is also.

For example, by analyzing the power consumption pattern of the terminal capacitor to which the heating or cooling device is connected, the power is not applied to the capacitor in seasons other than winter or summer, or for lighting equipment capacitors that are turned on at a certain time of each season. Since the power can be cut off at a time other than the corresponding time, unnecessary power consumption that is consumed in maintaining the standby mode of the electrical appliance can be prevented.

In particular, when the network type power management system according to the present invention is applied to a building including an office having a large number of personal computers having a power consumption of 15 W or more in the standby mode, the power is transferred to the terminal capacitor connected to the computer. The energy consumption in the standby mode is expected to be able to achieve a significant cost savings.

In addition, according to the analysis of the pattern of time of work by season and day of the week, power supply required for lighting of lighting equipment or operation of air conditioners can be performed by scheduling the terminal outlet 110 instead of the entire floor or the entire office.
