  On the other hand, some inventions mainly aiming at grasping the state of use of electrical equipment by users, particularly elderly people living alone, rather than controlling each electrical equipment have been disclosed. For example, Patent Literature 3 discloses a “life monitoring system”, which includes a circuit for obtaining operation information and operation information in an electric pot used at home, and an electric pot dedicated to monitoring. By preparing this dedicated electric pot in the monitoring subject's home, the monitoring subject's life is monitored. The obtained operation information or operation information is centrally managed as information from a large number of monitoring subjects, and can be viewed by a monitoring person using a WWW (World Wide Web) server on the Internet.

Further, Patent Document 4 discloses a “living information detection system that is installed in the home of a care recipient and outputs a life information signal as information relating to the opening and closing of a door and other people's living activities as a“ care recipient safety confirmation system ”. An invention has been disclosed that can easily and reliably confirm the safety of a care recipient such as an elderly person living alone or a non-healthy person.

Further, in step S1-4, first, whether or not the power-on detection sensor 4 is disconnected from the power cord 8 is detected based on the presence or absence of a signal from the sensor attachment / detachment detection unit 20 of the power-on detection sensor 4. Here, if a desorption signal is detected, the process proceeds to step S1-7 and an alarm is transmitted. If it is determined that there is no abnormality, the process proceeds to step S1-5, and is compared with the set time width that should not be used, based on the electric device usage information for each group number or ID of the electric device. In this way, it is checked whether there is an abnormality in the use outside of the hours. Here, if it is used outside the set time, it will progress to step S1-7 and will transmit an alarm. If it is determined that there is no abnormality, the process proceeds to step S1-6, and this time, whether or not there is an abnormality that the electric device to be used is not used by comparing with the set time width to be used. Check. If it is not used within the set time, the process proceeds to step S1-7 to transmit an alarm.
If there is no abnormality or after sending an alarm in step S1-7, the process proceeds to step S1-8, and steps S1-3 to S1-7 are executed for all groups and IDs. move on. In the predetermined time schedule, if it is the transmission time, the process proceeds to step S1-10 to transmit the electric appliance energization information (energization signal).

  In FIG. 6B, when the transmission / reception unit 28 of the receiving unit receives an energization signal transmitted from the sensor control device, a reception interrupt occurs. This is because the transmission / reception unit 28 is always in a receivable state. When a reception interruption occurs, reception signal analysis is performed as step S2-1, and when an energization signal is confirmed, it is stored in the data storage unit 31 shown in FIG. . When data accumulation is complete, the interrupt ends.

Next, the management organization of the energization state management system according to the present embodiment will be described with reference to FIGS.

The processing unit 54 reads the power consumption value per unit time for each monitored device existing in the monitored facility 1 from the facility information database 59 and uses the energization signal transmitted from the receiving unit for each monitored device. Power consumption can be calculated. The power consumption calculated for each monitoring target device is transmitted to the monitoring facility 18 via the transmission unit 56 and the line connection unit 14.
The input and setting of the power consumption value per unit time for each monitoring target device will be described later with reference to FIG.

  The authentication unit 43 accepts a monitoring request from a monitor by a web page on the Internet or a dialing operation of a telephone, reads the electrical device usage information stored in the device usage database 58 for each monitored device, and can be browsed by the processing unit 54 And is displayed or output as an electric equipment usage report on browsing means such as the external monitoring terminal 16 or the facsimile 17 in the monitoring facility 18. Further, the browsing means may be an electric product such as a personal computer, a home video game machine, or a word processor that can browse Web pages on the Internet. Moreover, as a portable browsing means that a supervisor carries and browses, a mobile phone that can browse web pages on the Internet, a portable personal computer, a portable information terminal, and the like may be used. Further, it may be a facsimile or a telephone that receives telephone guidance by voice synthesis. Although the management organization 13 is provided in the present embodiment, a workstation or the like can be connected to the reception unit 6 of each facility, and this can be used as the management organization 13.

FIG. 8A is a flowchart of a main flow of information processing in the monitoring control device of the energization state management system according to the present embodiment, and FIG. 8B represents an interrupt flow when an energization signal is received. It is a flowchart.
When the control unit of the management organization 13 has not received the electrical equipment usage information or the alarm information from the receiving unit of the monitoring target facility, as shown in FIG. After confirming the number, for each ID number, it is checked whether or not it is a transmission time in step S3-2. If it is the transmission time, a use report transmission request is issued in step S3-3. Do. At that time, according to the transmission method and transmission date and time of the electrical device usage report registered in advance in all the monitoring target devices stored in the facility information database 59, the processing unit 54 performs monitoring while making a processing / transmission request for the electrical device usage report. Wait for reception of electrical equipment usage information signal from the target facility.

Next, when the electrical equipment usage information signal is received, as shown in FIG. 8B, in step S4-1, the electrical equipment usage information signal is analyzed by the signal analysis unit 51, and the unique ID number and signal are displayed as an alarm signal. Then, it is classified as one of the electric device use signal, the date / time request signal, and the registration signal, and is transferred to the control unit 52. The control unit 52 performs the following processing depending on the type of signal.
If the received signal is determined to be an alarm signal in step S4-2, in step S4-3, the processing unit is used in accordance with the alarm signal transmission method registered in advance in the facility information database 59 using the unique ID number as a database search key. A processing / transmission request is made to 54. In that case, it may be processed and transmitted as a text message instead of a warning voice signal or a graphic signal expressing the warning with a symbol or the like.
In this embodiment, regarding the energization information, there are two reception signals, an alarm signal and an electrical equipment usage information signal, but the alarm signal for use outside use hours or unused within use hours is provided by the management organization 13. It may be generated. In this case, the energization signal is received from the receiving unit, and the energization time is compared with the time width to be used or not to be used stored in the facility information database 59, so that the overtime use is not performed. Alternatively, an alarm signal is generated when it is determined by the control unit 52 that it is unused within the usage time.

If the received signal is determined to be an electric equipment usage information signal in step S4-4, in step S4-5, the unique ID number is used as a database search key, and the equipment usage database 58 is classified for each monitoring target equipment. Store and manage device usage information. If the monitoring target device is not registered, the electrical device usage information is not stored or managed.
If the received signal is determined to be a date / time request signal in step S4-6, date / time information is read from a clock unit (not shown) connected to the signal analysis unit 51 in step S4-7 to receive the monitored facility at the transmission source. Send date and time information to the unit. By doing in this way, the precision of the date information recorded on the receiving unit of the monitoring object facility can be improved.

  If the received signal is determined to be registered information in step S4-8, the device information of the monitored device is registered in the facility information database 59 using the unique ID number as a database search key in step S4-9. A data area is secured in the database 58. Even when the device information is changed, a registration request signal is transmitted from the receiving unit of the monitoring target device. In this case, a data area that has already been completed is not secured.

The control unit 52 counts the number of times each received signal is received for each device to be monitored, charges the service contents at the time of registration (pay-as-you-go system, fixed system), and charges together with the monthly basic usage fee.
When the processing unit 54 receives the processing / transmission request from the control unit 52, the processing unit 54 reads the information format corresponding to the transmission destination of the electrical device usage report or alarm information from the processing / transmission rule database 55, and the monitoring read from the device usage database 58. Create an electrical device usage report to send the electrical device usage information of the target device to the supervisor. After processing, the transmission unit 56 selects a communication network such as the Internet 10 or the telephone line 15 that matches the external terminal of the supervisor, and performs transmission. When the external terminal is a telephone, the synthesized sound is reproduced by the transmission unit 56.

  The above is the means for the monitor to passively browse the electrical device usage report of the monitored device. In the embodiment of the present invention, the monitor can actively browse the electrical device usage report of the monitored device. The electrical device utilization report is created as a list in which a plurality of home appliances are arranged along the time axis so that the usage status of the plurality of electrical devices can be understood at a glance.

The transmission request for the electrical device usage report from the supervisor can be made on the Web page, or from the telephone or facsimile. A transmission request from the supervisor is sent to the authentication unit 53 via the line connection unit 14. Since transmission requests from telephones and facsimiles use push-line DTMF (Dual Tone Multi Frequency) signals, the DTMF signal analysis unit 61 connected to the authentication unit 53 analyzes the unique ID number and authentication number. When the unique ID number and the authentication number are input, the control unit 52 compares the authentication number with the authentication number of the monitoring target device recorded in advance in the facility information database 59. Process and send reports. If the authentication numbers do not match, a message to that effect is displayed on the external terminal and the transmission request acceptance process is terminated.
At this time, the control unit 52 counts the number of transmissions of the electrical device usage report, and charges for each monitored device or each facility in accordance with the service content at the time of registration (payment rate system, fixed system). Make a charge with.

The authentication of the user is usually performed by the unique ID number of the receiving unit and the authentication number set in advance. However, the use of one monitor viewing the electrical device usage information of a number of monitored devices (for example, the head office) If a manager who operates multiple other branch offices monitors the operating status of electrical equipment at each branch office, etc., a special access number and authentication number different from the ID number unique to the supervisor are issued. In addition, it is possible to browse a large number of devices to be monitored and information on the usage of electrical equipment in facilities.
In addition, by selecting an arbitrary past period or electrical equipment, it is possible to display a graph of arbitrary electrical equipment usage information, or to enable a supervisor to easily estimate the operating status of monitored equipment using statistical analysis techniques. To improve convenience.

  Next, the operation of the data management server installed in the management organization will be described using FIG. FIG. 9 is a flowchart of information processing in the data management server of the energization state management system according to the present embodiment. The data management server is provided in the transmission unit 56 and is connected to the Internet network. E-mail and data information can be transmitted to a data management server on the Internet.

  In FIG. 9, in step S5-1, it is determined whether or not the transmission unit 56 of the management organization 13 has received a signal. If received, the signal received in step S5-2 is analyzed. At that time, the device to be monitored can be identified by decoding the unique ID number transmitted from the receiving unit included in the signal. Whether or not this signal is an alarm signal is determined in step S5-3, and if so, signal processing of alarm information is performed in step S5-4. As a result, an alarm is issued from the transmitter 56 to the supervisor. When sending an alarm to a destination registered in advance, or when creating an electrical device usage report for 24 hours in addition to the alarm and sending it attached, etc. It can be selected.

On the other hand, if it is determined in step S5-3 that it is not an alarm signal, it is determined in step S5-5 whether the request signal is a report transmission request signal. If so, an electric equipment usage report is transmitted to the supervisor in step S5-6. If it is a report transmission request signal, the device to be monitored or the receiving unit is identified from the unique ID number included in the signal, and the electric device usage report based on the electric device usage information stored in the electric device usage database is generated. Send to a destination registered in advance.
When it is determined that the signal is not one of the signals and after transmitting the respective information, the signal returns to a state of waiting for the signal again.

  The operation of the FAX & TEL server installed in the management organization will be described with reference to FIG. FIG. 10 is a flowchart of information processing in the FAX & TEL server of the energization state management system according to the present embodiment. The FAX & TEL server is provided in the transmission unit 56 and is connected to a telephone line network. Telephone guidance by facsimile or voice synthesis can be performed. It is also possible to receive a browsing request from a supervisor and transmit an electric equipment usage report.

  In FIG. 10, when a signal is received in step S6-1, the received signal is analyzed in step S6-2. If it is determined in step S6-3 that the transmission request is related to alarm information, alarm information transmission processing is performed in step S6-4. In that case, similarly to the mail server, it is possible to identify the monitoring target device or the receiving unit by decoding the ID number unique to the receiving unit or the monitoring target device included in the signal. Further, the content of the alarm information transmission process is the same as step S5-4 described with reference to FIG. However, it is not a form of e-mail but transmission by telephone or fax.

  On the other hand, if it is determined in step S6-3 that the request is not a transmission request relating to alarm information, the process proceeds to step S6-5, where it is determined whether the request is a report transmission request. In the case of YES, the process for transmitting the electrical equipment usage report is performed in step S6-6. The processing here is the same as that of the mail server except that it is performed by means of telephone or facsimile. If NO, it is determined in step S6-7 whether the request is a browsing request. If it is a browsing request, the browsing process of an electric equipment utilization report will be implemented at step S6-8. When it is determined that the signal is not one of the signals and after transmitting the respective information, the signal returns to a state of waiting for the signal again.

  Here, with reference to FIG. 11 to FIG. 13, description will be added regarding the browsing process in response to the browsing request for the electrical device usage report by the supervisor. The supervisor calls the electrical equipment utilization report guidance dial of the management organization and wants to browse the ID number unique to the receiving unit of the monitored facility or the monitored equipment, the pre-registered authentication number, according to the guidance by voice synthesis. When the date and time of the electric equipment usage report and the browsing method (facsimile or voice synthesis) are dialed in, the FAX & TEL server creates an electric equipment usage report by facsimile or voice synthesis based on the input information and sends it to the supervisor. Is.

FIG. 11 is a flowchart of a browsing process in response to a browsing request for an electric equipment usage report. FIG. 12A is a conceptual diagram of a screen prepared on a dedicated terminal for making a browsing request, and FIG. It is a conceptual diagram of the screen of the electric equipment utilization report shown by the supervisor.
In FIG. 11, in step S7-1, a login screen 62 as shown in FIG. 12A is displayed. In step S7-2, an authentication number previously assigned to the monitor or registered by the monitor is input to the authentication number input window 65a. In addition, a unique ID number registered for the receiving unit or the monitoring target device is input to the serial number input window 64a, and the authentication confirmation button 66 is pressed to prompt authentication determination (step S7-3). Here, when the authentication number is different, or when the ID number and the authentication number are inconsistent, and further operations are not permitted, the permission process is performed in step S7-4, and the authentication number is determined. You must start again from the input.

  If the authentication ends normally, a menu screen is displayed in step S7-5. Accordingly, it is determined whether or not it is a browsing request (step S7-6), and in the case of a browsing request, a report browsing process is performed (step S7-7), and a screen 70 as shown in FIG. Is displayed. On the other hand, when the setting is changed (step S7-8), the setting changing process is performed (step S7-9). When the report browsing or setting change processing is completed, or when it is neither a browsing request nor a setting change request, it is determined whether or not to log out (step S7-10), and logout processing is performed (step S7-11). ) Or return to the menu screen and try again.

Here, a description is added to the screen 62 on the dedicated terminal prepared for login shown in FIG. On the screen 62, the system title 63 is displayed in the center, and in the left column, an instruction manual display button 67 and a help display button 68 are provided. And help are displayed and function as support when using the system.
12B includes a serial number display field 64b and an authentication number display field 65b. However, although the unique ID number is displayed as it is and can always be confirmed, an asterisk mark or the like is displayed on the authentication number so that the information is not inadvertently known to others.

  The end button 78 is clicked at the time of logout described above with reference to FIG. By clicking the execution button 84, for example, data can be installed on the hard disk of the personal computer operated by the supervisor. In this case, data is transmitted from the processing unit 54 shown in FIG. Furthermore, the contents registered by the supervisor with the management organization can be confirmed by clicking the confirmation button 80, and the registration contents can be changed by clicking the change button 81. It is also possible to modify.

A date display column 72 and a facility name display column 71a are provided at the upper part of the right column, so that the monitoring target facility being viewed by the monitor can be confirmed and the time information on the contents being confirmed can be obtained. Can do. Further, there is a group name / equipment name display column 71b. In the figure, there is a display of XX section, and an electrical apparatus display column 77 is provided for displaying a list of electrical devices that include this section as one group. It has been. On the right side of the electric device display column 77, an electric device usage status display column 73 is provided for how each electric device is used, and the usage time zone display bars 75a to 75e, 75g, 75h The usage status can be grasped. The respective uses are grouped on the same time axis by the time display column 74, and are devised so that it is possible to grasp at a glance which electrical device is used at which time. A situation explanation display field 76 is provided at the lower part so that the findings are communicated.
By displaying a specific text message as shown in this column in place of the display such as the above-mentioned usage time zone display bar 75f, when the supervisor is inexperienced or inexperienced However, it is possible to easily understand the situation.

In the present embodiment, as shown in FIG. 12, the energization information of each electric device is displayed in a graph from a point back several hours (6 to 12 hours) from the latest (current time), and the electric device usage information can be easily browsed. It is processed as follows.
Also, the usage time zone display bar 75f is displayed as an alarm because a desorption signal is issued from the sensor desorption detection unit because the power-on detection sensor of the television has been removed. By displaying a graphic different from the normal usage time zone display bar in this way, an abnormality with respect to any sensor can be clarified at an early stage, thereby facilitating the check by the supervisor. Furthermore, although it is not displayed in this drawing, the set time width may be visualized and displayed in the electric equipment usage status display field 73. In addition, it is possible to monitor more accurately and easily by distinguishing the use time zone display bar with different colors or patterns when the energization is in the time width that should be used and the time width that should not be used. . It is also effective to blink the usage time zone display bar when the use is considered abnormal or when it is not used, and when the power-on detection sensor is disconnected from the power cord.

  By listing the electric devices included in the predetermined group in this way, the usage status of the plurality of electric devices can be confirmed at a glance, and the use of these electric devices can be well understood. That is, in FIG. 12B, for example, in the morning, there is an operator who uses the PC 2 by turning on the fluorescent lamp 1, the TV is switched on during the lunch break, and the PC 1 is also used during the lunch break. In the afternoon, two fluorescent lamps 1 and 2 were used and two personal computers PC1 and PC2 were used, and the air conditioner was switched off during the lunch break to save power. The copier was in full operation even during the lunch break.

  Furthermore, information such as the telephone number of the monitored facility can be added to the electrical equipment usage report and displayed. In addition, by selecting an arbitrary past period or electrical device, it is possible to display a graph of arbitrary electrical device usage information, or a supervisor can easily estimate the operation pattern of a monitored device or facility using a statistical analysis method. Like that. Such an operation can be performed by accessing the device usage database 58 via the line connection unit 14 shown in FIG. 7, reading out necessary information, processing the information by the processing unit 54, and transmitting it from the transmission unit 56. Become. The monitor can operate from the outside of the management organization 13 via the Internet 10 or the telephone line 15.

  For browsing requests on the Web, the browsing amount and browsing time of electrical equipment usage reports, the number of times electrical equipment usage information is downloaded, etc. are managed by the monitoring and control device, and the service content at the time of registration (pay-as-you-go, fixed) In addition to this, a charge is made for each monitored facility or each monitored device, and charged together with the monthly basic usage fee.

Next, an electrical equipment usage report transmitted through various media will be described with reference to FIG. FIG. 13 is a conceptual diagram of an electrical equipment usage report transmitted from the energization state management system according to the present embodiment. 13, parts that are the same as the parts shown in FIG. 12 are given the same reference numerals, and descriptions thereof will be omitted.
The contents of this electric equipment utilization report are almost the same as the browsing screen shown in FIG. 12, but there is no serial number display field or authentication number display field. Such an electric device usage report is transmitted by facsimile or transmitted to an external monitoring terminal such as a computer. The home appliance use report shown in FIG. 13 relates to passive browsing by the supervisor described with reference to FIG.

  In addition, such an electric equipment usage report is obtained by downloading electric equipment usage information of a monitored facility from a download page on the Web operated by a management organization, and personal computers and home video game machines when not connected to the Internet. It is also possible to enable browsing using dedicated software that operates on In order to enable such downloading, for example, it is necessary to install an FTP (File Transfer Protocol) server in the management organization.

As described above, in the energization state management system according to the embodiment of the present invention, the equipment necessary for the monitored facility analyzes the power-on detection sensor and the sensor control device for detecting the energization information of the electrical equipment and the usage status of the electrical equipment. And only the receiving unit storing information such as the transmission destination. Therefore, it is not necessary to provide a dedicated electrical device as a monitoring device or to modify the electrical device, and it is possible to greatly reduce the economical introduction cost and psychological burden on the user.
In addition, management of energization information in a monitoring facility uses an ID or group number for a plurality of power-on detection sensors and sensor control devices, and is also unique to a receiving unit installed for each monitoring target facility. Therefore, it is easy to cope with the increase in the monitoring target facilities and the monitoring target devices included in the monitoring target facilities and perform high-precision management.

Further, in the processing unit of the monitoring control device installed in the management organization, the information accumulated in the device usage database for the power-on detection sensors and sensor control devices of a plurality of electrical devices is displayed in a list along the time axis. Since they are integrated, the usage status of each electrical device can be grasped at a glance including their usage correlation, so that the operating status of the monitored device can be accurately grasped.
Moreover, the monitor not only waits for the electrical equipment usage report transmitted from the management organization, but also actively accesses the management organization from various external information terminals, so that the monitoring in the monitored facility can be traced back to the present or the past. Information on the usage status of target devices can be obtained. In that case, security is ensured by requiring an authentication number and the like.

Next, setting of the power consumption value per unit time for each monitoring target device will be described with reference to FIG. FIG. 14A is a screen for inputting power consumption per unit time for each monitoring target device, and FIG. 14B shows detection of usage at a time that should not be used for each monitoring target device. It is a screen for input of detection outside use time and unused detection within the time to be used, that is, input without detection within use time.
In FIG. 14A, an input / setting screen 83 is provided with a setting status display field 89, which displays work contents. In addition, a name display column 71a and a group name / device name display column 71b are also provided, and it is possible to confirm which monitoring target device belongs to which group of which monitoring target facility.
On the left side of the screen 83, there is a display as shown in FIG.

Each device to be monitored is displayed in the electric device display column 77, and the power consumption per unit time is input to the power consumption setting column 87 for each. Two triangles shown on the left side of the power consumption setting column 87 mean scroll buttons. Regarding these two triangular buttons, all the other triangular buttons described in the drawings of the present application also mean scroll buttons. By clicking this button, the power consumption value per unit time can be raised or lowered in this figure, and the time and effort of inputting as a digital value can be saved. In other fields, not only scrolling numbers but also devices, facilities, groups, etc. may be changed by scrolling. Of course, numbers and letters can be entered without scrolling.
In the situation explanation display column 76, advice regarding the setting of power consumption is displayed as a text message.

On the screen 88 shown in FIG. 14 (b), the times for detection outside use time and non-detection within use time are input to the non-use-time detection setting column 90 and the non-use-time detection setting column 91, respectively. Once input is made in these fields, devices for actual detection are further entered in the check fields 92 and 93 for confirmation.
In the setting status display field 89, time management setting is displayed. Other parts that are the same as those in FIG. 14A are denoted by the same reference numerals, and description of the configuration is omitted.
14A and 14B, the monitoring control device 12 of the management organization 13 is activated from the external monitoring terminal 16 and connected to the facility information database 59 through the control unit 52. Although not shown in FIG. 7, it may be displayed in the same manner by connecting an input device to the monitoring control device 12.
Further, as described above, the input unit 33 of the receiving unit 6 is used without inputting the facility information database 59 of the monitoring control device 12 while displaying the screens shown in FIGS. 14 (a) and 14 (b). Alternatively, settings relating to power consumption per unit time, detection outside use time, and detection not using within use time may be performed. When the setting is performed by the monitoring control device 12, the setting data can be transferred from the facility information database 59 to the unique number storage unit 35. This is because it is necessary to acquire time width data for determining whether the energization signal received by the transmission / reception unit 28 is detected outside use time or not detected within use time. In addition, the power consumption can also be confirmed in the receiving unit 6, which is convenient.

Finally, a list regarding power consumption will be described with reference to FIG. FIG. 15 is a conceptual diagram showing power consumption as a list on a screen for each group of facilities to be monitored. In FIG. 15, a screen 94 displays a group name display field 96 in addition to a date display field 72 and a name display field 71 a indicating the name of the facility with a configuration similar to that in FIG. In this figure, the power consumption on August 21, 2003 is shown in the electric equipment power consumption display column 95 in units of kWh for each group in the monitoring target facility. Of course, it is also possible to display a power consumption list for each monitoring target device and each monitoring target facility, in addition to each group.
In the column on the left side of the screen 94, in addition to the serial number display field 64b and the authentication number display field 65b, an end button 78, a confirmation button 80, a change button 81, and information for downloading the information shown in this figure are downloaded. An execution button 99 and a confirmation button 100 for confirming management of the energized state are provided.
In this way, it is possible to grasp at a glance which facility, group, or device power consumption is high or low by representing it in a list.

As described above, according to the energization state management system according to the present embodiment, a small power-on detection sensor is installed in the power cord of the monitoring target device to detect the energization state and simultaneously calculate the power consumption. It is excellent in minimal invasiveness and can be easily installed at low cost in an existing system, so that the power consumption and energization state of electrical equipment in the facility can be easily grasped, and power saving and energy saving can be promoted.
In addition, since the power-on detection sensor is also equipped with a sensor for detecting desorption, when it is intentionally removed or unintentionally removed, it is detected by the desorption signal, so that an abnormality can be recognized early. . In addition, the presence of such a sensor can be expected to prevent intentional removal.

  Any organization or organization that uses electrical equipment, such as companies and public institutions, can contribute to energy and energy savings while grasping and managing the power distribution status. In particular, by preventing unnecessary or unauthorized use of electrical equipment, it is possible to promote power saving and energy saving and to prevent moral deterioration in the organization.
