Description

  The present invention relates to a computer control system, a control device, a control method, and a program. In particular, the present invention relates to a computer control system that controls the operating state of a computer, a control device, a control method for controlling the control device, and a program for the control device.

  In buildings and factories that receive electricity due to high voltage and extra high voltage, an electric power meter for trading with a built-in 30-minute maximum electricity meter is installed, and the power company measures the amount of electricity used. The 30-minute maximum demand electricity meter measures the amount of electricity used for 30 minutes and calculates the average power consumption. The 30-minute maximum watt-hour meter is configured to store and display the maximum value for one month.

  The current electricity rate system is calculated based on the basic rate determined by contracted power and the energy rate determined by the amount of power used. The contract fee is determined on the basis of demand, which is the average power used for demand restriction. Specifically, the maximum value of each demand becomes the maximum demand, and this value affects contract power. For this reason, even if the power consumption is the same, the electricity bill will increase greatly if the contract power increases. Therefore, it is an effective means to reduce contract power for reducing energy costs. Moreover, suppressing demand by demand monitoring also reduces the amount of power used, leading to energy saving. For this purpose, a power monitoring system having a demand monitoring function capable of continuously monitoring demand becomes effective.

  For example, in the case of a contractor who receives less than 500 kW of contract power received by high voltage, the largest value is used for calculation of basic power among the maximum demand power of the month and the past 11 months. Specifically, when a large demand value is generated even once, the demand value is applied for one year.

  On the other hand, in the case of a contractor with a contract power of 500 kW or higher received by a high voltage, the contract power is determined by consultation. Specifically, when the maximum demand power exceeds the contract power, an extra penalty will be paid. At that time, a new contract power change is discussed based on the maximum demand power.

  Therefore, in recent years, in order to prevent the power used in buildings or factories that receive electricity from high voltage or extra high voltage from exceeding contract power, lighting or air A system has been proposed in which the power consumption is stopped or the power consumption is reduced.

  Further, as a technique capable of preventing wasteful power loss, a network power control system that can suppress power loss without requiring a power control device is known (see, for example, Patent Document 1). . In this network power supply control system, when one of the computers in the network to which a plurality of computers and I / O (Input / Output) devices are connected is turned off, the other computers and I / Os are connected. Check the operating state of the O device. In this network power supply control system, a message to turn off the I / O device is output to the display screen only when all other computers are off and the I / O device is on. . In this network power supply control system, when a message for prompting the I / O device to be turned off is output, the computer is put on standby until the I / O device is turned off.

JP-A-10-254589

  In the network power supply control system described in Patent Document 1, when the computer recognizes that the power of the I / O device is turned off, the computer itself is also terminated, thereby preventing unnecessary power loss. However, simply introducing such a network power supply control system does not function as a measure to prevent the power used in the facility from exceeding the contracted power.

  Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the scope of claims, and are combinations of features described in the embodiments. Not all are essential to the solution of the invention.

  FIG. 1 shows an example of a use environment of a personal computer control system 100 according to an embodiment. The personal computer control system 100 is a system that controls the operating state of a personal computer. The personal computer may be an example of the “computer” in the present invention.

  The personal computer control system 100 includes a server 110 and a plurality of personal computers 130a, b, c,... (Hereinafter collectively referred to as personal computers 130). Each personal computer 130 is installed in one building. The server 110 is a device that controls the operating state of each personal computer 130. Server 110 is communicatively connected to each personal computer 130 via communication line 150. The server 110 is electrically connected to a power meter 160 installed in the building. The wattmeter 160 is a device that measures power used in a building. The communication line 150 includes a computer network such as the Internet, a core network of a communication carrier, and various local networks. The server 110 may be an example of a “control device” in the present invention. The building may be an example of a “facility” in the present invention.

  In the personal computer control system 100 having such a configuration, the personal computer 130 transmits usage status data indicating the usage status of the user's own device to the server 110. When the server 110 receives the usage state data transmitted from the personal computer 130, the server 110 specifies the time that has elapsed since the personal computer 130 is no longer used, based on the usage state of the personal computer 130 indicated by the usage state data. In addition, the server 110 monitors the power used in the building measured by the power meter 160. Then, if there is no risk that the power used will exceed the contracted power in the building, the server 110 will change the operating state of the personal computer 130 to the operation with low power consumption if the elapsed time after the personal computer 130 is not used exceeds 10 minutes. Control data for controlling to shift to the state is transmitted to the personal computer 130. Alternatively, when there is a possibility that the power used exceeds the contracted power in the building, the server 110 transmits the control data to the personal computer 130 when the elapsed time after the personal computer 130 is not used exceeds 5 minutes. . When the personal computer 130 receives the control data transmitted from the server 110, the personal computer 130 controls the operation state of its own device to shift to a state of less power consumption based on the control data. In addition, 10 minutes may be an example of the “first threshold value” in the present invention. Further, 5 minutes may be an example of the “second threshold value” in the present invention.

  As described above, in the personal computer control system 100, the power used in the building can be prevented from exceeding the contract power by controlling the operating state of the personal computer 130. At that time, in the personal computer control system 100, since the use state of the personal computer 130 by the user is referred to, there is no possibility that the use of the personal computer 130 by the user will be hindered.

  Preferably, the server 110 causes the operating state of the personal computer 130 to shift to a state of low power consumption by stopping the supply of power to the display electrically connected to the personal computer 130 as the control data. Send control data to control. The display may be an example of the “peripheral device” in the present invention.

  Thus, in the personal computer control system 100, when the personal computer 130 is not used by the user for a predetermined time or longer, the power consumption of the personal computer 130 can be suppressed by turning off the power of the display of the personal computer 130. it can.

  More preferably, before the server 110 transmits control data to the personal computer 130, the notification data indicating a notification message to notify the user that the operating state of the personal computer 130 shifts to a state of low power consumption. Is transmitted to the personal computer 130. When the personal computer 130 receives the notification data transmitted from the server 110, the personal computer 130 displays a notification message indicating to the user that the operation state of the own device shifts to a state where the power consumption is low, which is indicated by the notification data. Output.

  As described above, in the personal computer control system 100, the user is notified in advance that the operating state of the personal computer 130 shifts to a state where the power consumption is low. As a result, for example, a user who is in trouble when the operating state of the personal computer 130 shifts to a state where the power consumption is low can avoid the shift of the operating state by using the personal computer 130 temporarily.

  More preferably, after the server 110 transmits the control data, if there is no risk that the power used will exceed the contracted power in the building, if the time elapsed since the personal computer 130 is no longer used exceeds 15 minutes, Re-control data for controlling again to shift the operating state of the personal computer 130 to a state where the power consumption is further reduced is transmitted to the personal computer 130. Alternatively, when the server 110 transmits the control data and there is a possibility that the power used may exceed the contracted power in the building, if the time elapsed after the personal computer 130 is not used exceeds 7 minutes 30 seconds, Are sent to the personal computer 130. When the personal computer 130 receives the recontrol data transmitted from the server 110, the personal computer 130 controls the operation state of its own device to shift to a state where the power consumption is further reduced based on the recontrol data.

  As described above, in the personal computer control system 100, even after the operating state of the personal computer 130 is shifted to a state where the power consumption is low, if the personal computer 130 is not used by the user, the operating state of the personal computer 130 is changed. Since the state is shifted to a state where the power consumption is further reduced, the power consumption can be more effectively reduced.

  More preferably, as the re-control data, the server 110 temporarily stops the operation of the personal computer 130 and makes it stand by in a power saving state, so that the operating state of the personal computer 130 is shifted to a state with less power consumption. Re-control data for control is transmitted.

  In this manner, in the personal computer control system 100, the power consumption of the personal computer 130 can be further suppressed by temporarily stopping the operation of the personal computer 130 and waiting in the power saving state.

  More preferably, before sending the re-control data to the personal computer 130, the server 110 sends an inquiry message inquiring whether or not the operating state of the personal computer 130 may be shifted to a state of less power consumption. The inquiry data shown is transmitted to the personal computer 130. When the personal computer 130 receives the inquiry data transmitted from the server 110, the personal computer 130 inquires whether or not the operating state of the own device indicated by the inquiry data may be shifted to a state where the power consumption is lower. Output inquiry message. When the personal computer 130 receives an input indicating whether or not it is allowed to shift the operating state of its own device to a state with less power consumption in response to the output inquiry message, the response content is displayed. The response data shown is transmitted to the server 110. Alternatively, even when the personal computer 130 cannot accept an input to respond to the output inquiry message, the personal computer 130 transmits response data indicating that fact to the server 110. When the server 110 receives the response data transmitted from the personal computer 130, the response content indicated by the response data shifts the operating state of the personal computer 130 to a state with less power consumption when transmitting the re-control data. If it is indicated that it is acceptable, or if it is indicated that the input of the response content has not been accepted, the re-control data is transmitted to the personal computer 130.

  As described above, in the personal computer control system 100, when the operating state of the personal computer 130 is shifted to a state where the power consumption is lower, it is confirmed in advance with respect to the user whether or not it is allowed to shift. Accordingly, for example, a user who is troubled when the operating state of the personal computer 130 shifts to a state where the power consumption is further reduced can refuse such control.

  More preferably, the server 110 calculates the usage time of the personal computer 130 from when the personal computer 130 is activated by the user until the personal computer 130 is stopped by the user. In addition, the server 110 controls the control time so that the operating state of the personal computer 130 is shifted to a state of low power consumption after the personal computer 130 is activated by the user and before the personal computer 130 is stopped by the user. Is calculated. Then, after calculating the usage time of the personal computer 130, when the personal computer 130 is activated by the user, the server 110 stores data indicating the computer usage time of the personal computer 130 and the control time of the personal computer 130. It transmits to the personal computer 130. Then, the personal computer 130 receives data indicating the usage time and the control time from the server 110. Then, the personal computer 130 outputs information indicating the usage time indicated by the received data and the control time.

  As described above, in the personal computer control system 100, when the personal computer 130 is activated by the user, the usage time when the personal computer 130 was last used by the user and the operating state shifts to a state where the power consumption is low within the usage time. The controlled time is displayed on the display. Thereby, in the personal computer control system 100, when the user of the personal computer 130 takes a seat away at a meeting or going out, it can be expected that the personal computer 130 and the display are frequently turned off.

  In the present embodiment, the configuration in which the personal computer control system 100 includes one server 110 has been described for the purpose of preventing the description from becoming complicated. However, the personal computer control system 100 includes a plurality of servers 110. You may prepare.

  FIG. 2 shows an exemplary block configuration of the server 110. The server 110 includes a power usage monitoring unit 111, a usage state data receiving unit 112, a non-use time specifying unit 113, a notification data transmitting unit 114, an inquiry data transmitting unit 115, a response data receiving unit 116, a control data transmitting unit 117, a usage It has a time calculation unit 118, a control time calculation unit 119, and a time data transmission unit 120. The function and operation of each component will be described below.

  The power usage monitoring unit 111 monitors power usage in the building. Specifically, the power usage monitoring unit 111 receives power usage data indicating power usage in a building from the power meter 160. Then, when the used power in the building indicated by the used power data is likely to exceed the contract power, the used power monitoring unit 111 sends data indicating that fact to the non-use time specifying unit 113 and the control data transmitting unit 117. send. Further, when there is no possibility that the power used in the building indicated by the power usage data exceeds the contract power, the power usage monitoring unit 111 sends data indicating that fact to the non-use time specifying unit 113.

  The usage status data receiving unit 112 receives usage status data transmitted from the personal computer 130. Specifically, when the usage status data receiving unit 112 receives the usage status data transmitted from the personal computer 130, the usage status data receiving unit 112 converts the usage status data into the non-use time specifying unit 113, the usage time calculation unit 118, and the control time calculation unit 119. And to the time data transmission unit 120.

  The non-use time specifying unit 113 specifies the time that has passed since the personal computer 130 is no longer used, based on the use state of the personal computer 130 indicated by the use state data received by the use state data receiving unit 112. Specifically, when the unused time specifying unit 113 receives the usage state data from the usage state data receiving unit 112, the personal computer 130 is used based on the usage state of the personal computer 130 indicated by the usage state data. Identify the time that has passed since it disappeared. In addition, the non-use time specifying unit 113 monitors the use power by monitoring the data indicating that the power used in the building may exceed the contract power or the data indicating that the power used in the building may not exceed the contract power. Received from the unit 111. The non-use time specifying unit 113 stops using the personal computer 130 when the data received last from the used power monitoring unit 111 indicates that the used power in the building does not exceed the contracted power. When 9 minutes and 30 seconds have elapsed, data indicating that fact is sent to the notification data transmission unit 114. Further, the non-use time specifying unit 113 stops using the personal computer 130 when the data received last from the used power monitoring unit 111 indicates that the used power in the building does not exceed the contracted power. When 10 minutes have elapsed, data indicating that fact is sent to the control data transmission unit 117. Further, the non-use time specifying unit 113 stops using the personal computer 130 when the data received last from the used power monitoring unit 111 indicates that the used power in the building does not exceed the contracted power. When 14 minutes and 30 seconds have elapsed, data indicating that is sent to the inquiry data transmission unit 115. Further, the non-use time specifying unit 113 stops using the personal computer 130 when the data received last from the used power monitoring unit 111 indicates that the used power in the building does not exceed the contracted power. When 15 minutes have passed, data indicating that fact is sent to the control data transmission unit 117. The non-use time specifying unit 113 stops using the personal computer 130 when the data received last from the used power monitoring unit 111 indicates that the used power in the building may exceed the contracted power. When 4 minutes and 30 seconds have elapsed, data indicating that is sent to the notification data transmission unit 114.

  When the response data transmission unit 137 of the personal computer 130 receives the response data from the response input reception unit 136, the response data transmission unit 137 transmits the response data to the server 110.

  When the response data receiving unit 116 of the server 110 receives the response data transmitted from the personal computer 130 (S116), the response data receiving unit 116 transmits the response data to the control data transmitting unit 117.

  The control data transmission unit 117 receives from the response data reception unit 116 response data indicating the response content indicating whether or not the operating state of the personal computer 130 may be shifted to a state with less power consumption. Then, when the control data transmission unit 117 indicates that the response content indicated by the response data received from the response data reception unit 116 may shift the operating state of the personal computer 130 to a state with less power consumption. (S117: Yes) Or, if it indicates that the input of the response content could not be accepted, in the processing of the subsequent step S121, the operating state of the personal computer 130 is shifted to a state where the power consumption is further reduced The re-control data for performing re-control so as to be performed is transmitted to the personal computer 130.

  On the other hand, when the control data transmitting unit 117 indicates that the response content indicated by the response data received from the response data receiving unit 116 does not shift the operating state of the personal computer 130 to a state where the power consumption is lower. (S117: No), the re-control data is not transmitted to the personal computer 130.

  When the data received last from the power usage monitoring unit 111 indicates that the power usage in the building is unlikely to exceed the contracted power (S118: No), the non-use time specifying unit 113 When 15 minutes have passed since it was not used (S119: Yes), data indicating that fact is sent to the control data transmission unit 117.

  When the control data transmission unit 117 receives data indicating that 15 minutes have passed since the personal computer 130 is no longer used from the non-use time specifying unit 113, the control data transmission unit 117 shifts the operating state of the personal computer 130 to a state where the power consumption is further reduced. The re-control data for performing re-control so as to be transmitted is transmitted to the personal computer 130 (S121). For example, the control data transmission unit 117 temporarily stops the operation of the personal computer 130 as the re-control data and puts the personal computer 130 into the sleep state by making it stand by in the power saving state, and changes the operating state of the personal computer 130 to the power consumption. The re-control data for controlling to shift to a state with less state is transmitted.

  When the control data receiving unit 138 of the personal computer 130 receives the recontrol data transmitted from the server 110, the control data receiving unit 138 sends the recontrol data to the operating state control unit 139. When receiving the recontrol data from the control data receiving unit 138, the operating state control unit 139 performs control so as to shift the operating state of the own apparatus to a state where the power consumption is further reduced based on the recontrol data. In this way, the personal computer 130, for example, temporarily stops its operation and shifts to a sleep state in which it waits in a power saving state.

  On the other hand, if the data received last from the used power monitoring unit 111 indicates that the used power in the building may exceed the contracted power (S118: Yes), the non-use time specifying unit 113 is a personal computer. When 7 minutes and 30 seconds elapse after 130 is no longer used (S120: Yes), data indicating that is sent to the control data transmission unit 117.

  When the control data transmission unit 117 receives from the non-use time specifying unit 113 data indicating that 7 minutes and 30 seconds have elapsed since the personal computer 130 is no longer used, the control data transmission unit 117 transmits the re-control data to the personal computer 130 as described above. Send to.

  Thereafter, the personal computer 130 performs the same processing as described above. In this way, the personal computer 130, for example, temporarily stops its operation and shifts to a sleep state in which it waits in a power saving state.

  FIG. 9 shows an example of time information 400 displayed on the display of the personal computer 130. The time information 400 includes information 410 on the usage time from when the personal computer 130 was last activated by the user until it was stopped, and the operating status of the personal computer 130 to a state where the power consumption is low by the server 110 within the usage time. The control time information 420 controlled to be transferred is displayed.

  FIG. 10 shows an example of the operation flow of the server 110. In the description of this operation flow, both FIGS. 1 to 9 are referred to.

  When the usage state data receiving unit 112 of the server 110 receives the usage state data transmitted from the personal computer 130 in step S102 of the operation flow shown in FIG. 6 described above, the usage state data is transmitted to the usage time calculation unit 118 and the control. The data is also sent to the time calculation unit 119 and the time data transmission unit 120.

  The usage time calculation unit 118 receives the usage state data from the usage state data reception unit 112. Then, the usage time calculation unit 118 is based on the usage state information of the personal computer 130 indicated by the usage state data until the personal computer 130 is stopped by the user after the personal computer 130 is activated by the user. The usage time of the personal computer 130 is calculated (S201). More specifically, when the usage status data indicates that the personal computer 130 has been activated by the user, the usage time calculation unit 118 stores the activation time. When the usage state data indicates that the personal computer 130 has been stopped by the user, the usage time calculation unit 118 stores the stop time. Then, the usage time calculation unit 118 calculates the usage time of the personal computer 130 from the stored start time to stop time. Then, the usage time calculation unit 118 sends data indicating the calculated usage time to the time data transmission unit 120.

  On the other hand, the control data transmission unit 117 shifts the operating state of the personal computer 130 to a state with less power consumption in step S111 of the operation flow shown in FIG. 6 or in step S121 of the operation flow shown in FIG. When the control data for controlling is transmitted to the personal computer 130, the data indicating the control time is transmitted to the control time calculation unit 119.

  The control time calculation unit 119 receives usage state data from the usage state data reception unit 112. In addition, the control time calculation unit 119 receives data indicating the control time from the control data transmission unit 117. The control time calculation unit 119 then starts the personal computer 130 by the user based on the usage state information of the personal computer 130 indicated by the usage state data and the control time, and then stops the personal computer 130 by the user. In the meantime, a control time for controlling the operating state of the personal computer 130 to shift to a state of less power consumption is calculated (S202). More specifically, the control time calculation unit 119 starts the control time calculation process when the use state data indicates that the personal computer 130 has been activated by the user. When the control time calculation unit 119 receives data indicating the control time from the control data transmission unit 117, the control time calculation unit 119 stores the control time. When the usage state data indicates that the personal computer 130 has been operated to return to the normal usage state, the control time calculation unit 119 stores the return time. Then, the control time calculation unit 119 calculates and stores the control time from the control time to the return time. The control time calculation unit 119 repeats the control time calculation process until usage state data indicating that the personal computer 130 has been stopped by the user is received from the usage state data reception unit 112. When the control time calculation unit 119 receives use state data indicating that the personal computer 130 has been stopped by the user from the use state data receiving unit 112, the control time calculation unit 119 calculates the control time obtained by accumulating the control times stored so far. The indicated data is sent to the time data transmission unit 120.

  The time data transmission unit 120 receives the usage state data from the usage state data reception unit 112. In addition, the time data transmission unit 120 receives data indicating the usage time from the usage time calculation unit 118. Further, the time data transmission unit 120 receives data indicating the control time from the control time calculation unit 119. When the usage state of the personal computer 130 indicated by the data received from the usage state data receiving unit 112 indicates that the personal computer 130 has been activated by the user, the time data transmission unit 120 reads from the usage time calculation unit 118. Data indicating the usage time indicated by the received data and the control time indicated by the data received from the control time calculation unit 119 is transmitted to the personal computer 130 (S203).

  In this way, when the time data receiving unit 140 of the personal computer 130 receives the data indicating the usage time and the control time from the server 110, the time data receiving unit 140 sends the data to the time information output unit 141. When the time information output unit 141 of the personal computer 130 receives the data indicating the usage time and the control time from the time data receiving unit 140, the information indicating the usage time and the control time indicated by the data is displayed on the display. Output.

  In this way, time information as shown in FIG. 9 is displayed on the display of the personal computer 130.

  As described above, in the personal computer control system 100, by controlling the operating state of the personal computer 130, it is possible to prevent the power used in the building from exceeding the contract power. At that time, in the personal computer control system 100, since the use state of the personal computer 130 by the user is referred to, there is no possibility that the use of the personal computer 130 by the user will be hindered.

  Further, in the personal computer control system 100, when the personal computer 130 is not used by a user for a predetermined time or longer, the power consumption of the personal computer 130 can be suppressed by turning off the display of the personal computer 130.

  Further, in the personal computer control system 100, the user is notified in advance that the operating state of the personal computer 130 shifts to a state where the power consumption is low. As a result, for example, a user who is in trouble when the operating state of the personal computer 130 shifts to a state where the power consumption is low can avoid the shift of the operating state by using the personal computer 130 temporarily.

  Further, in the personal computer control system 100, even after the operating state of the personal computer 130 is shifted to a state where the power consumption is low, if the time when the personal computer 130 is not used by the user continues, Therefore, the power consumption can be reduced more effectively.

  Further, in the personal computer control system 100, the power consumption of the personal computer 130 can be further suppressed by temporarily stopping the operation of the personal computer 130 and waiting in the power saving state.

  Further, in the personal computer control system 100, when the operating state of the personal computer 130 is shifted to a state where the power consumption is lower, it is confirmed in advance with respect to the user whether or not it is allowed to shift. Accordingly, for example, a user who is troubled when the operating state of the personal computer 130 shifts to a state where the power consumption is further reduced can refuse such control.

  In the personal computer control system 100, when the personal computer 130 is activated by the user, the personal computer 130 has been used by the user last time, and the operating state is shifted to a state in which less power is used within the usage time. The control time is displayed on the display. Thereby, in the personal computer control system 100, when the user of the personal computer 130 takes a seat away at a meeting or going out, it can be expected that the personal computer 130 and the display are frequently turned off.
