Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric equipment management apparatus, an electric equipment, and a power supply control adapter for managing power supply (supply) to a plurality of electric equipment.

[0002]

2. Description of the Related Art At present, a wide variety of types of electric equipment are widely used in ordinary households. There is a need for a home bus system that collectively manages these. In a company, the superiority of the function is confirmed by laying a dedicated line such as a LAN (Local Area Network). Even in home electric appliances, digital VH
Devices that can be controlled using a dedicated line compatible with the IEEE 1394 bus, such as an S-VTR, are becoming widespread.

[0003] However, in a general house (home) at present, cost management is still insufficient for centralized management using a dedicated line, and transition to centralized management of a dedicated line is in progress.

Therefore, as described in Japanese Patent Application Laid-Open No. 09-084146, an inexpensive home automation system for a specific application using a commercial power line which does not require new facility construction as a network is introduced. . The control target here is the power management of each electric device connected to the power line. A dedicated terminal is integrally installed in an outlet connecting each electric device, and data is exchanged with a dedicated controller by a control signal superimposed on a commercial power line. As the control contents,
When the power consumption approaches the maximum power consumption stipulated by the contract with the power company, that is, the state immediately before the breaker is turned off, the warning lamp blinks or a warning sound is issued to notify the user. In addition, when newly turning on the power of an electric device, if the allowable maximum power is exceeded, the power may not be turned on, or the electric device with a lower priority may be set according to the priority set for each electric device. The power is turned off or the power supply to the electric device that can reduce the power consumption is suppressed, and the power is controlled to be equal to or less than the allowable maximum power consumption. Such power supply control prevents the power consumption from exceeding the allowable maximum power consumption and prevents the breaker from falling.

[0005] Further, the controller checks daily power consumption, calculates an electricity bill, enables monthly power management, and constitutes a system for calling attention to power saving.

It is described that these controls are performed using a power line as a network, but it is also possible to use a dedicated line separated from the power line.

[0007]

According to the power management system described above, power supply to a plurality of electric devices can be managed so as not to exceed the maximum power consumption defined by a contract between each house and a power company. . However, a power line wired to a house is first supplied to a main breaker through an integrating wattmeter, and then branched to a plurality of sub-breakers, for example, in a room unit, and connected to each electric device downstream thereof. The configuration is generally as follows.

The maximum allowable power consumption of the main breaker is, for example, 30 A, and the maximum allowable power consumption of each sub-breaker at the branch destination is, for example, 15 A. Generally, the sum of the maximum allowable power consumption of the sub-breakers does not match.

Therefore, when the power supply is managed based on the maximum allowable power consumption of the main breaker, the electric equipment connected via the first sub-breaker branched from the main breaker allows the electric power of the first sub-breaker to be controlled. If a situation occurs where the allowable maximum power consumption is exceeded, the first sub-breaker is cut off, and the power supply to the electric equipment subordinate to the first sub-breaker is stopped. A similar thing is
This is true for all other sub-breakers that branch off from the main breaker.

One object of the present invention is to manage the power consumption of each electric device so that each breaker does not operate with respect to a plurality of electric devices connected downstream of a plurality of sub-breakers branched from a main breaker. An object of the present invention is to provide an electric device power supply management control device that can perform the above-described operations.

Another object of the present invention is to reduce the power consumption of the electric equipment power supply management and control device.

Still another object of the present invention is to enable an administrator to monitor or give an operation instruction to the system from outside or from a remote location.

Still another object of the present invention is to provide a system at a low cost.

Still another object of the present invention is to provide an electric device suitable for controlling power supply by the electric device power supply management control device.

Still another object of the present invention is to provide a power supply control adapter suitable for controlling power supply by the electric device power supply management control device.

[0016]

According to the present invention, there is provided an electric equipment power supply management control device for calculating the electric power consumption for each of a plurality of electric equipment connected downstream of a plurality of sub-breakers branched from a main breaker. Then, by controlling the power supply to each electric device so as to be within the allowable power range of each breaker, the power supply such that each breaker does not operate is realized.

Further, management control information is reported to the system management means via the telephone line, and power supply control to the electric equipment is executed based on an instruction from the system management means.

Further, the control contents can be set by remote control means.

Further, the management control information is displayed on an electric device having a display function.

Further, the electric device of the present invention transmits the device identification information, the power consumption information and the power on / off information to the power supply management control device so as to be adapted to such power supply management control. In accordance with the control signal, the control to cut off the power supply circuit or limit the power consumption is performed.

Further, a function of displaying the management control information under the control of the power supply management control device is provided.

In addition, the power supply control adapter of the present invention controls the power supply of an electric device having no function as described above by the power supply management control device. And power on / off information is transmitted to the power supply management device, and power supply to the connected electric equipment is cut off in accordance with a control signal from the power supply management device.

An embodiment of an electric device suitable for such power supply management control will be described with reference to FIG. FIG.
Is a block diagram illustrating only related units for power supply management control, and other units are not illustrated.

The electric equipment (for example, VTR 11) 20
No. 0 draws the power cord 202 from the housing 201, and connects the plug 203 provided at the tip thereof to the outlet 131a provided on the sub power line 111 to receive power.

The power supply cord (power supply line) 202 branches into a power supply relay 205 and a control power supply circuit 206 after passing through a power consumption measuring means 204 inside the housing.

The power supply relay 205 is connected to the electric device 200.
It is a normally open relay that interrupts the power supply to the original functional means. The control power supply circuit 206 is a power supply circuit for a power supply management control system of the electric device 200.

A control microcomputer 207 as an arithmetic processing means
Receives power supplied from the control power supply circuit 206, acquires the power consumption measured by the power consumption measuring means 204 based on the program stored in the memory 208 and various control data, and receives the power via the communication circuit 209. Connected to the control line 144a connected to the control line terminal 210 to communicate with the sub power supply management device 141, and in accordance with the on / off instruction from the power button 211a of the operation panel 211 and the instruction from the sub power supply management device 141, A control process for switching the power supply relay 205 on and off is performed. Control microcomputer 207
When the electric device 200 has a monitor screen like the TV 12 or a personal computer system (not shown), the control processing for displaying the control state information transmitted from the sub power supply management device 141 on the monitor screen is also performed. To do. When the electric device 200 has a configuration capable of controlling power consumption in a plurality of stages, the control microcomputer 207 controls the original function means of the device so as to be in an operation mode in which power consumption is reduced. Be able to do it. Further, when the control microcomputer 207 cannot communicate with the auxiliary power supply management device, the control microcomputer 207 determines that the electric device 200 is not used in the electric device power supply management control system and does not execute the power supply management control.

The memory 208 includes, as control data for the electric device 200, a device name (device identification information required for a product code), rated power consumption, power on / off information, power consumption, and the like.
Information such as power consumption (integrated amount within a predetermined period) is stored.

The control microcomputer 207 and the memory 208
May be installed exclusively in this power supply management control system, but it is economical if the electrical equipment uses a control microcomputer and a memory provided for controlling the original function means of the electrical equipment.

In the electric power supply management control system configured as described above, the auxiliary power supply management devices 141 and 142
In order to execute power supply management control according to each electric device, each electric device 1 connected to each of the sub power lines 111 and 112
A process for recognizing 1 to 19 is performed. This connection device recognition,
Each electric device 11 via the control lines 144a to 144j
19 through communication with the control microcomputer 207 to obtain and store the product code and rated power consumption of the device. This process is performed between an electric device and a new device each time the device is newly connected.

Here, an example of the power supply management control according to the electric equipment will be described.

Since the refrigerator 16 requires power supply for 24 hours, the power supply restriction is not controlled unless an abnormality occurs in the refrigerator main body. This is achieved by limiting the power supply to the device. For devices such as the electric kettle 19 and an electric carpet (not shown) that cause less trouble due to power supply restriction, when the state exceeds the allowable maximum power consumption, the heat retention state is immediately released (the power supply relay is turned off). Then, a control method of restarting when the power of another electric device is turned off and a state where the power consumption is within the allowable maximum power consumption is adopted is adopted.

For an electric device 200 such as the VTR 11 that operates by timer reservation, the reservation information (reservation time, recorded program, etc.) of the electric device 200 is transferred to the sub power supply management device 141 and managed. And the electrical equipment 2
00, the control microcomputer 207 of the electric device 200 is controlled so as to put the electric device 200 in a sleep state by opening the power relay 205, and the reserved time stored in the sub-power supply management device 141 is approached (for example, 5 minutes ago) By the way, the control microcomputer 2 of the electric device 200
07, a power-on control signal is supplied to start the electric device 200, and a start-up state confirmation signal is transmitted to the electric device 2
At the time when the current time and the reservation information are received from the control microcomputer 207 of 00, the sub power supply management device 141 transmits the electric device 200 to the electric device 200 at any time to activate the electric device 200. Then, the sub-power supply management device 141 sends an operation end signal from the control microcomputer 207 of the electric device 200 to M
When S1 is received, the power relay 2 of the electric device 200
A control signal for disconnecting the electric device 05 is transmitted to the control microcomputer 207 of the electric device 200 to put the electric device 200 in a paper feeding state. Such power supply management control is effective for reducing the standby power of the electric device operating at the reserved time.

Here, the main power supply management device 140 executes the management control with the allowable maximum power consumption as 30 A of the main breaker 120, and the sub power supply management device 141 performs the management control with the allowable maximum power consumption as 15 A of the sub breaker 121. And the case where the sub power supply management device 142 executes the management control with the allowable maximum power consumption as 20 A of the sub breaker 122 will be described.

The electric equipment (VTR 11 to air conditioner 15) managed and controlled by the sub power supply management device 141 consumes 1 power.
Assuming that the electric equipment (the refrigerator 16 to the electric kettle 19) managed and controlled by the sub-power supply management device 142 is in the operation state of the power consumption 15A, the sub-power supply management devices 141 and 142 In addition, the above-described power supply management control for each electric device is performed on the sub-breakers 121 and 122 managed by the respective devices so as not to exceed the allowable maximum power consumption, and the power supply management control state (the power-on state and the operating state). Electrical equipment and its power consumption)
To the main power supply management device 140. The main power supply management device 140 has a total power consumption of 28 A by the electric devices connected to the sub power lines 111 and 112, and is equal to or less than the allowable maximum power consumption (30 A) set in the main power supply management device 140. Therefore, each sub-power supply management device 141,
The power supply management control in 142 is not limited. However, the fact that the power consumption has reached a predetermined value of the allowable maximum power consumption, for example, 90% or more, is notified to the user as an alarm, and when the TV 12 is in the operating state, the power consumption reaches 90% or more on the monitor screen. The management control state information for displaying the fact that the operation has been performed is transmitted to the TV 12.

If the total power consumption exceeds the allowable maximum power consumption 30 A by newly turning on the power button 211 a of the electric device and operating the electric device from this state, the main power supply management device 140 The sub-power supply management device 1 is configured to shut off the power of an electric device that permits the restriction, for example, the electric kettle 19 or an electric carpet (not shown) so that the total power consumption falls within an allowable range.
The control for restricting the power supply management control in 41 and 142 is performed, and information indicating the management control state is displayed on the TV 12. When the power consumption exceeds the permissible maximum power consumption 15A, 20A, the sub-power supply management devices 141, 142
The power supply is controlled so as to keep the power consumption within an allowable range by shutting off the power supply of an electric device, for example, the electric kettle 19 or an electric carpet (not shown), which permits the power supply restriction, and the information indicating the management control state is transmitted to the TV 12. Is transmitted to the TV 12 so as to be displayed on the TV 12. If the newly powered-on electrical device is an electrical device that permits power supply restriction, the power supply to the already-powered power-suppliable device is cut off to enable a new power-on device, or In this case, the power supply to the new electric device is not permitted, and the fact is displayed.

By such power supply management control, it is possible to avoid the inconvenience that the breakers 120 to 122 operate and the power supply line is cut off when the breaker 120 to 122 exceeds the allowable maximum power consumption.

Considering the room layout of a general house, it is divided into living, dining, and kitchen, and the use of electric equipment used there naturally becomes similar. Accordingly, the main power supply management device 140 and the sub power supply management devices 141, 141
By adapting the system including 142, for example, the main power supply management device 140 sends control lines 143a,
Sub-power supply management device 14 directly controlled via 143b
1 and 142, and the above-described power supply management control is performed for each room by the sub-power supply management devices 141 and 142, so that the usability of the electric device is improved.

Main power supply management device 140 and sub power supply management device 1
41, 142 cooperate to form breakers 120-122.
Power management control based on the maximum allowable power consumption of the electrical equipment, and if a leak occurs in the electrical equipment or a trouble that makes it impossible to control the electrical By transmitting an abnormal signal from the sub-power supply management devices 141 and 142 that manage the power supply to the devices to the main power supply management device 140, the main power supply management device 140
Displays the content of the abnormality on the monitor screen and issues an alarm, and further controls the power supply to the failed electrical device to be interrupted without affecting other sub-power supply management devices. Can be controlled.

The main power supply management device 140, the sub power supply management devices 141 and 142, and the electric devices 11 to 19 cooperate to cooperate with each other in the power consumption (integrated power) of the electric devices 11 to 19 within a predetermined period. Is measured, tabulated and managed.

Since the main power supply management device 140 and the sub power supply management devices 140 and 142 need to be constantly operating to manage each electric device, as shown in FIG. It is effective from the viewpoint of power saving if it is built in an electric device that needs to be energized for a long time.

The main power supply management device 140 is connected to the sub power supply management devices 141 and 142 in parallel or in series, and the sub power supply management devices 141 and 142 are connected to the respective electric devices in parallel. For example, the management devices 141 and 142 may be built in a hub of an arbitrary device.

Such power supply management control is performed by the sub power line 11
If there is a conventional device having a configuration incapable of adapting to the power supply management control in the electric device connected to the power supply control unit 1, 112, the intended purpose of the power supply management control cannot be achieved.
However, it is uneconomical to dispose of conventional electrical equipment that cannot be accommodated. Therefore, it is desirable to provide auxiliary means for easily adapting to such conventional electric equipment.
