Thus, power adjustment can be performed more efficiently.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)

  FIG. 1 is a system configuration diagram of the power adjustment system of the present embodiment. In the present embodiment, a power adjustment system of one office will be described.

  The business office 1 is provided with three elevators 1 to 3 and five air conditioners A to E (hereinafter simply referred to as air conditioners), and power is supplied from the power supply unit 2. The office 1 is further supplied with electric power to the lamps and OA devices in the rooms on each floor.

  Moreover, the elevator 1 installed in the office 1 is an elevator for luggage. For example, the initial power is 30 KW and the rated power is 15 KW. The level of importance of the elevator 1 is set to “3”, and the IP address is WWW.abcdef.jp. Of the importance levels, the level “1” is the most important, and the level of importance decreases in the order of “2”, “3”,.

  Moreover, elevators 2 and 3 are elevators for employees, the initial power is 20 KW, and the rated power is 10 KW. The level of importance of the elevators 2 and 3 is “1”, and the IP addresses are WWW.ghijk.jp and WWW.lmnop.jp.

  On the other hand, the initial power of the air conditioner A is 2 KW, the rated power is 1 KW, the level of importance is “2”, and the IP address is WWW.qrstu.jp. Similarly, the initial power and rated power, the level of importance, and the IP address are set for the air conditioners B, C,. Furthermore, power consumption, an IP address, and the like for an unillustrated lamp and OA device are set.

  The elevators 1 to 3, the air conditioners A to E, the lights, and the OA devices are connected to the management server 5 via the Internet (network line). FIG. 2 is a diagram showing this network configuration. The elevators 1 to 3, the air conditioners A to E, the electric lights, and the OA devices are set with IP addresses as described above, and information is exchanged via the network.

  The elevators 1 to 3, the air conditioners A to E, and the like are devices having a remote power on / off function and have a LAN board. The LAN board is connected to a network line (communication line) and receives a power-on command from the management server. Each LAN board is supplied with power and normally functions as a communication interface, but also performs on / off control of power to the apparatus main body. Therefore, when the above devices are connected to the network line, only the LAN board is always supplied with power.

  FIG. 3 is a diagram illustrating the configuration of the management server 5. In the figure, a management server 5 is constituted by a CPU 6, a ROM 7, a RAM 8, and the like, performs processing according to a program stored in the ROM 7, and accesses recording devices 9a and 9b connected to the management server 5 as necessary.

  In addition, necessary information is displayed on the display 10, and information is exchanged via a communication line. The system control of this example is executed in accordance with a program stored in the ROM 7, but as shown in the figure, a recording medium 12 such as a CD-ROM, a flexible disk, or MO is attached to a media driver 11 disposed in the computer. The program may be mounted and read from the recording medium 12 for use.

  FIG. 4 is a diagram for explaining the configuration of a database constructed in the external recording device 9a. In the figure, a device name, an initial power when starting the device, and a rated power are registered in the database, and level information indicating the importance of the device is registered. An IP address is also registered in the device name.

  For example, the elevator 1 installed in the office 1 is a luggage elevator, and as described above, the initial power is 30 KW and the rated power is 15 KW. The elevator 1 is for luggage, the importance level is set to “3”, and the IP address is WWW.abcdef.jp. Accordingly, corresponding information is registered in the database constructed in the recording device 9a.

  Elevator 2 is for employees. As mentioned above, the initial power is 20 KW, the rated power is 10 KW, the importance level is set to “1”, and the IP address is WWW.ghijk.jp Yes, the corresponding information is registered in the database. Hereinafter, the elevator 3, the air conditioners A to E, the electric lights, and the like are also registered in the database shown in FIG.

  In the above configuration, the processing operation of this example will be described below.

  5 and 6 are flowcharts for explaining the processing operation of this example. First, in FIG. 5, the total amount of power used in the current office 1 is calculated. This process is performed based on information transmitted to the management server 5 from the elevators 1 to 3, air conditioners A to E, electric lights, etc. via the network, and consumed by the elevators 1-3, air conditioners A to E, electric lights, etc. It is the sum total of the electric power. The CPU 6 of the management server 5 performs this calculation (step (hereinafter referred to as S) 1).

  Next, it is determined whether the power supply of a new device is turned on (S2). This determination is made based on information supplied from each device, and the management server 5 determines which device is powered on based on information transmitted via the network.

  Here, when the power-on of a new device is detected (S2 is YES), it is confirmed which device is turned on next (S3), and the initial power of the device turned on is read from the storage device 9a. (S4). For example, when the power supply of the air conditioner B of the database shown in FIG.

  Next, the management server 5 (CPU 6) adds the initial power to the total amount of power used in the current office 1 (S5). For example, if the total amount of power currently used is 48 kW, the initial power 1.5 kW is added to obtain information on the power consumption of the addition result (49.5 kW).

  Next, it is determined whether the added value exceeds the peak value (S6). Here, if the peak value is, for example, 50 KW, the added value does not exceed the peak value in this case (S6 is NO), and therefore the power-on of the device (for example, the air conditioner B) is instructed (S7). In this case, the management server 5 sends an instruction to the air conditioner B via the network, and the power supply of the air conditioner B is remotely processed.

Input by reason.
On the other hand, when the added value exceeds the peak value (S6 is YES), drive stop processing of any device is performed. In this case, the database is first searched, and the least important device is selected (S8 shown in FIG. 6). For example, in the example shown in FIG. 4 described above, the elevator A having the importance level “3” is selected.

  Next, the rated power of the selected device is read and subtracted from the total amount of power currently used (S9). For example, when the total amount of power currently used is 60 kW, the rated power 15 kW of the elevator A is subtracted. Then, it is determined whether the subtraction result is equal to or lower than the peak value (S10). If the subtraction result is equal to or lower than the peak value (S10 is YES), the driving of the device (elevator A) is stopped (S11). However, in this case, in the drive stop process of the apparatus, for example, if the elevator A is currently moving, the drive of the elevator A is stopped after the operation is completed. Thereafter, the power of the device to be newly driven (for example, the above-described air conditioner B) is turned on (S12).

  On the other hand, if the subtraction result is still greater than or equal to the peak value (S10 is NO), it is determined whether or not the processing has been performed on all the devices in the office 1, and the processing returns to the above-described processing (S8) and the next importance level. Processing is performed for devices with a low level. In the example shown in FIG. 4, the next searched device is the air conditioner A with the importance level “2”, and the processing (S8 to S12) is executed in the same manner as described above. If the subtraction result is equal to or less than the peak value (S10 is YES), the driving of the device (air conditioner A) is stopped (S11), and the power of the device (air conditioner B) to be newly driven is turned on (S12). ).

If the subtraction result does not fall below the peak value even after the above processing (S10 is YES), the same processing is repeated for all devices to display an error.
As described above, according to the processing of this embodiment, when a new device in the office 1 is used, the management server 5 (CPU 6) always determines the peak value, so that power supply exceeds the peak value. Can be used with good power efficiency.

In the description of the above embodiment, the business office 1 has been described. However, the present invention is not limited to the business office, and can be similarly applied to, for example, a home power adjustment system. You can also Furthermore, it can be applied to power adjustment of the entire building or power adjustment in a specific area.

(Second Embodiment)

Next, a second embodiment of the present invention will be described.
This example is an invention that performs power adjustment based on the power consumption characteristics stored in the storage device 6b. This will be specifically described below.

  FIG. 7 is a diagram showing the configuration of the database used in this example. In this example, a database shown in FIG. 7A is constructed in the recording device 9a, which has basically the same configuration as that of FIG. 4 described above, except that a link code is stored. This link code is address information linked to the power consumption characteristic database constructed in FIG.

  That is, the link code is a code indicating the address of the power consumption characteristic of each device stored in the storage device 6b, and indicates the storage area of the power consumption characteristic of the corresponding device. For example, the link code 001 indicates an area where the power consumption characteristics of the elevator 1 are stored, and the link code 002 indicates an area where the power consumption characteristics of the elevator 2 are stored.

Hereinafter, the link code 003 indicates the area where the power consumption characteristics of the elevator 3 are stored, and the link code 004 indicates the area where the power consumption characteristics of the air conditioner A are stored, as shown in FIG.
For example, the power consumption characteristics of the elevator 1 are as shown in FIG. 8, and since the elevator 1 is used for luggage, it is used, for example, early in the morning (6 am to 7 am), and the frequency of use thereafter is The power consumption characteristics become a corresponding curve. This power consumption characteristic is created by examining the operation history of the elevator 1 for a certain period. Specifically, the operation state for a certain period is measured under the control of the controller 1a provided in the elevator 1, and the power consumption characteristics of the elevator are acquired according to the day of the week and the time. The power consumption characteristic is registered in a storage unit (not shown) in the elevator 1 and is also registered in the database of the management server 5.

  Further, the power consumption characteristics of the elevator 2 are as shown in FIG. 9, and since the elevator 2 is for employees, for example, morning and evening time zones (8am to 9am, 5pm to 7pm) ), The average usage is performed in other time zones, and the power consumption characteristic is also a curve shown in FIG. This power consumption characteristic is also created by examining the operation history of the elevator 2 for a certain period. Further, the power consumption characteristic of the elevator 3 is a curve similar to the characteristic of the elevator 2 because the elevator 3 is for employees.

  Furthermore, the power consumption characteristic of the air conditioner A is as shown in FIG. 10, and it becomes a substantially constant power consumption curve in the time zone (8 am to 7 pm) when the office is used. Although not shown, the other air conditioners B to E have the same characteristics.

  This power consumption characteristic is created by investigating the driving history of the air conditioner A or the like for a certain period, specifically, measuring the operation state for a certain period under the control of the controller Aa provided in the air conditioner A or the like, The power consumption characteristics are acquired by taking into account not only time but also temperature, humidity, season, and other information.

  By configuring as described above, it is possible to perform power adjustment in consideration of the power consumption characteristics of each device, and it is possible to perform more efficient and precise power adjustment according to the control of the management server 5 (CPU 6). . For example, it is possible to predict the operation of each device over one day (24 hours), and power consumption exceeding the peak value can be avoided in advance.

In the description of the above embodiment, the establishment 1 has been described. However, the present invention is not limited to the establishment, and can be similarly applied to, for example, a home power adjustment system. It can also be applied. Furthermore, it can be applied to power adjustment of the entire building or power adjustment in a specific area.
(Embodiment 3)

Next, a third embodiment of the present invention will be described.
Unlike the first and second embodiments described above, this example is an example when applied to a power adjustment system in a home.

  FIG. 11 shows an example of a network in this case. The management server 15 is connected to devices such as a refrigerator, a microwave oven, a television, and a vacuum cleaner in the home via a network. In the management server 15, a database having the configuration shown in FIG. 12 is constructed. That is, as shown in the figure, initial power, rated power, and importance level of the refrigerator, microwave oven, television, vacuum cleaner, etc. are registered, and further, ID information of the device is stored. In this case, the management server 15 is connected via a network such as a LAN.

  For example, in the case of a refrigerator, the initial power is 0.5 kW, the rated power is 0.2 kW, and the level of importance is “3”. In the case of a microwave oven, the initial power is 1 KW, the rated power is 0.8 KW, and the importance level is “1”. Hereinafter, data such as initial power in a television, a vacuum cleaner, and the like are as shown in FIG.

  In this example, ID information is set for each apparatus, and the set ID information is also stored in the database shown in FIG. The management server 15 exchanges information with each device according to the ID information.

  The management server 15 performs power adjustment so as not to exceed the peak power in the home, as in the above-described embodiment. In the description of the above embodiment, when a new device is turned on, the power supply of the device with a low level of importance is cut off. However, drive control suitable for the device characteristics is performed without turning off the power supply. It is good also as a structure. For example, when the device that stops driving is an air conditioner, it is possible to perform control such that only driving of the compressor is stopped and driving is resumed at the timing when the peak value decreases.

  Moreover, it is good also as a structure which changes the temperature itself of an air-conditioner to low temperature, and performs control which changes the drive interval of a compressor. For example, FIG. 13 shows an example of this case, and the above-mentioned storage device 9a is further provided with a set temperature and reduced power table for each device. A table having such a configuration is prepared for each apparatus.

  FIG. 14 is a flowchart for explaining the processing in this case. When the peak value is finished as a result of the subtraction process by the management server 15, it is first determined whether or not it is necessary to stop the driving of the refrigerator (step (hereinafter referred to as ST) 1). This determination is made by referring to the table shown in FIG. 12 described above. For example, when the remaining power can be reduced by about 0.3 KW (YES in ST1), the temperature setting is then changed (ST2). For example, in the case of 0.3 KW, the set temperature is increased by 3 ° C. If power adjustment cannot be performed only by temperature control (ST1 is NO), the drive of the apparatus is stopped as described above.

In addition, although the said control is an example of a refrigerator, the same control is possible also with respect to the air conditioner used in a home. Further, it is possible to perform power adjustment by performing control such as adjusting the brightness of a light (not shown) or the like.
In the above description, the peak value of power is considered to be a short time, but it is also applicable to a case where the power continues for 30 minutes, for example. Further, the present invention is not limited to 30 minutes, and can be applied to cases of 10 minutes, 20 minutes, or 40 minutes.
(Fourth embodiment)

Next, a fourth embodiment of the present invention will be described.
FIG. 15 shows the system configuration of the power adjustment system of this example. As shown in the figure, in this example, a management server and each device are connected via the Internet. The management server 20 includes an air conditioner 21, a television 22, etc., as well as a power company 23, a weather information provider 24, a terbi station 25, etc. Connected to various content.

  The recording device 20a of the management server 20 stores an IP address in addition to the initial power, the rated power, and the importance level as described above. In addition, devices such as air conditioners acquire information on drive date, drive time, and power consumption as history information, and this information is stored in the recording unit of each device and sent to the management server 20. And stored in the recording device 20a. Further, when the management server 20 records the information in the recording device 20a, the management server 20 acquires the temperature and humidity information of the area where the device is installed and the weather information from the weather information providing company 24, and the driving date, driving It is linked to time information and recorded.

The power consumption of each device can also be obtained from the power company 23 in units of buildings and regions.
As described above, after the necessary meta information is accumulated in the management server 20, the power adjustment described above is performed, and the power that does not exceed the peak value for each region, each building, each office, or each home. Adjustments can be made. In particular, in the case of this example, it is possible to adjust the temperature of the air conditioner all at once, for example, according to a command from the electric power company 23.

  That is, the management server 20 can control the start, operation, stop, and power-off processing of each device connected to the management server 20 via the network, and is present in a certain area connected to the management server 20, for example. The temperature of the air conditioner can be lowered by 1 ° C. Therefore, power consumption can be controlled by a request from the power company 23, and accurate power adjustment can be performed by a request from the power company 23 based on the operation information. For example, when power consumption in a certain region is predicted to exceed the peak value, appropriate temperature drop information that does not exceed the peak value is obtained from the power company 23, and efficient power adjustment is possible.

  On the other hand, the following control is also possible. That is, it is possible to determine the state of the power consuming device in a certain home, cut off the power supply of unnecessary devices, and eliminate wasteful power. For example, if the temperature of an area where a home is obtained from the weather information provider 24 is 39 ° C, but the air conditioner is not used, but the TV or the light is on, Judging and shutting off the TV and electric power. By controlling in this way, waste of power can be eliminated.

  In the above example, the judgment is made based on the local temperature and the use of the air conditioner. However, for example, when the preset TV channel has not been changed for a long time, the TV power is turned off by going out or forgetting to turn off the TV. It is also possible to turn off the power of the television by determining that the is still on.

  Also, the change information of the television channel can be acquired by the management server 20, and this information can be stored in the recording device 9a. Therefore, for example, the terbi station 25 is an effective means of knowing the audience rating by checking the management server 20 with the channel change history information stored in the recording device 9a.

  Further, by connecting a monitoring device such as a monitoring camera or a monitor as a power consuming device to the management server 20 via a network, the room can be monitored and used for crime prevention or the like.

  Furthermore, by setting the access to the management server 20 from a mobile phone or PDA (personal digital assistant), the user can know the status of each device in the home via the management server 20, and can be opened outdoors as necessary. Therefore, it is possible to perform drive control and temperature control of an air conditioner refrigerator and the like.

In the description of the above embodiment, drive control and power adjustment of each device are performed via the management server 20, but a certain device, for example, an air conditioner may be used as a server. This is especially effective in homes, small facilities, and small offices.
In addition, although each device is intended for an air conditioner, an elevator, or the like, for example, a game machine or the like may be a target device of the present system.

  As described above, according to the present invention, it is possible to adjust the power consumed on a business unit basis, a company unit basis, or a home unit basis, and to provide an efficient power regulation system that reduces power charges. Can do.
