Description

  The present invention relates to a user terminal management system and method for managing the operating state of user terminals.

In recent years, office automation has become office automation (OA), and the power consumption of OA equipment including user terminals in the office accounts for 16% of the total power consumption in Japan (estimated by the Agency for Natural Resources and Energy).
For this reason, as a measure for suppressing global warming, power saving of user terminals such as personal computers in offices for power saving is desired.
In response to this power saving, it is important to reduce power consumption by user terminals as well as power saving in office lighting and air conditioning.

  The most commonly used method for reducing power consumption of the user terminal is to use a power consumption reduction function added to an OS (Operating System) installed in the user terminal. By setting the OS power consumption reduction function in advance, the power of the display device is turned off in accordance with the set condition, or the main body of the user terminal is shifted to the sleep mode. For example, as the setting of the OS power consumption, the non-operation time of the user terminal is counted, and each of the display device off, the transition to the sleep mode, and the shutdown is stepwise according to the length of the non-operation time. Are performed sequentially.

However, when the operating state of the user terminal is changed in stages according to the length of time of no operation, the user terminal is turned off for a certain period of time even if the user terminal is not operated or the user is absent. This is a waste of power consumption.
Therefore, there is a technique for providing an infrared sensor for detecting the presence or absence of a user in the user terminal and turning off the display device of the user terminal to reduce power consumption when it is detected that the user is not present near the user terminal. (For example, refer to Patent Document 1).

JP-A-10-326126

However, in Patent Document 1 described above, if the dead time of the infrared sensor is shortened in order to reduce waste of power consumption, the user uses the user terminal when the user does not move in front of the user terminal. Even if business is performed, it is determined that the user terminal is not present near the user terminal, and the display screen of the user terminal is frequently turned off. For this reason, when the business is interrupted, the business efficiency is lowered and the user feels stressed.
On the other hand, if the dead time of the infrared sensor is increased in order to reduce the stress on the user due to the display screen being frequently turned off, the power consumption is not controlled even when the user is not using the user terminal. The power reduction is insufficient.
In other words, simply checking the absence of a user with an infrared sensor has a trade-off relationship between user convenience and power consumption reduction, and only provides insufficient information for controlling the power-off of the user terminal. I can't.

On the other hand, in the case of a technology that turns off the power according to the non-operation state of the user terminal, when the user is browsing the document or e-mail displayed on the display screen for business, the user terminal is simply operated. As a state, the power of the user terminal is turned off.
In this case as well, as in Patent Document 1, the user's business efficiency is reduced, and the user is stressed.
Furthermore, when the OS is shut down or when the user goes to work and activates the user terminal, the user himself / herself needs to activate the user terminal, which takes time to start work on the user terminal. Efficiency will be reduced.

  The present invention has been made in view of such circumstances, and comprehensively determines no operation, location information, telephone use, etc., and detects a state in which the user terminal is not used in real time to save energy. A user terminal that is a system to be realized and that does not shift the user terminal to a mode that reduces power consumption even when the user terminal is not operated when it is estimated that the user is using the user terminal It is an object to provide a management system and method.

  The present invention has been made to solve the above-described problems, and a user terminal management system according to the present invention is a user terminal management system that manages an operating state of a user terminal, and the user terminal in the vicinity of the user terminal is The presence / absence of the user to be operated is detected, and the user position detection unit that outputs the user position information indicating the presence / absence of the user and whether or not the telephone corresponding to the user terminal is in a call are detected. A telephone state detection unit that outputs user call information indicating a user terminal operation detection that detects an operation state of the user terminal by the user and outputs user operation information indicating whether or not the user terminal is operated And the user position information, the user call information, and the user operation information, the operating state of the user terminal is changed to a mode for reducing power consumption. Characterized in that it comprises a mode control unit to shift to.

  In the user terminal management system of the present invention, when the mode control unit indicates that the user call information indicates that the user is in a call regardless of whether or not the user position information is the user, the user operation information is Even if it is determined that the user terminal is not operated, the operating state of the user terminal is not shifted to a mode for reducing power consumption.

  The user terminal management system of the present invention further includes a timer for counting time, and the mode control unit includes the user in the vicinity of the user terminal, the user terminal is not operated, and the telephone is talking. It is characterized by causing the timer to count a time during which the user terminal is not in the middle, and switching the operation mode of the user terminal to a power consumption reduction mode corresponding to the count value of the timer.

  In the user terminal management system of the present invention, the first set time, the second set time, and the third set time are previously written and stored in the mode control unit, and the mode control unit sets the count value to the first value. When the operating time of the user terminal is shifted from the normal mode to the display device off mode in which the power of the display device of the user terminal is turned off when one set time is exceeded, and the count value exceeds the second set time The operating state of the user terminal is shifted from the display device off mode to the sleep mode, and when the count value exceeds the third set time, the operating state of the user terminal is shifted from the sleep mode to the shutdown mode. And

  The user terminal management system of the present invention further includes an entry advance detection unit that detects that the user has entered a preset area and outputs user detection information indicating entry of the user into the area, A mode control unit activates the user terminal state when the user detection information is supplied.

  The user terminal management method of the present invention is a user terminal management method for managing the operating state of a user terminal, wherein the user position detection unit detects the presence or absence of a user operating the user terminal in the vicinity of the user terminal, User location detection process for outputting user location information indicating the presence / absence of a user, and a phone call state detection unit detects whether a call corresponding to a user terminal is in a call and indicates whether the call is in progress A user who outputs a user operation information indicating whether or not the user terminal is operated by detecting the operation state of the user terminal by the user and a user terminal operation detecting unit outputting information The operation state of the user terminal is determined based on the user position information, the user call information, and the user operation information. Characterized in that it comprises a mode control process unit to shift to a mode of reduced power consumption.

  According to the present invention, even when the user does not operate the user terminal, if the user is talking on the phone, the user terminal is set to a power consumption reduction mode (for example, the display device is turned off to turn off the power of the display device). Mode, sleep mode, and shutdown mode), when the user terminal is inactive and the phone is not in a call, the user terminal is shifted to the power consumption reduction mode, so that the user's business efficiency is not lowered. It becomes possible to reduce the power consumption of the user terminal.

It is a block diagram which shows the structural example of the user terminal management system by one Embodiment of this invention. It is a figure which shows the structural example of the position table previously written and memorize | stored in the position database. It is a figure which shows the structural example of the user table previously written and memorize | stored in the user database. It is a flowchart which shows the operation example of the management of the user terminal of the user terminal management system 1 by this embodiment.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a network of user terminals using a user terminal management system according to an embodiment of the present invention.
In FIG. 1, a user terminal management system 1 includes a position detection device 2, a terminal mode control device 3, a position database 4, and a user database 5. The user terminal 6 is installed corresponding to the user. Each of the transmitters 7 is arranged in the vicinity of each of the user terminals 6 operated by the user U (for example, provided on the ceiling at a position immediately above each of the user terminals 6), and identifies the transmitter. Information including information is continuously transmitted as a radio signal at a constant cycle by a weak electric wave reaching only the nearby user terminal 6. That is, in order to specify the position of each user terminal 6, each of the transmitters 7 is arranged in the vicinity of the corresponding user terminal 6. Each of the user terminal management system 1 and the user terminal 6 is connected by an information communication network I such as the Internet.

  Next, FIG. 2 is a diagram illustrating a configuration example of a position table that is written and stored in advance in the position database 4. This position table is a position table indicating correspondence between transmitter identification information of the transmitter 7 and terminal identification information of the user terminal 6 in the vicinity of the transmitter 7. That is, in the position table, the user terminal 6 operated by the user and the transmitter 7 that specifies the position of the user terminal 6 are associated with each other. Further, dummy transmitter identification information is provided in the position table, and terminal identification information that does not actually exist is stored in correspondence with the dummy transmitter identification information.

  Next, FIG. 3 is a diagram showing a configuration example of a user table written and stored in the user database 5 in advance. The user table includes terminal owner identification information for identifying the user U, telephone identification information for identifying a telephone (hereinafter referred to as a telephone terminal) used by the user U corresponding to the terminal owner identification information, and a user U's use. It is a table which shows a response | compatibility with the terminal identification information of the user terminal 6. FIG. The user table is provided with an entry flag for each terminal owner identification information. This entry flag is a flag indicating whether or not the user U has entered a specific area. For example, when the user U enters the room where the user terminal 6 operated by the user U or the building where the user terminal 6 operated by the user U is placed, “1” is written, When advancing from the area, “0” is written.

  Further, in the user table, a mode flag is provided for each terminal owner identification information, similarly to the entry flag. For example, this mode flag indicates the normal mode when “0” is written, indicates the display device off mode when “1” is written, and sleeps when “2” is written. Indicates the mode and indicates shutdown when “3” is written. This mode flag corresponds to the mode of the user terminal 6, and data indicating the mode, that is, a number, is rewritten by the mode control unit 32.

  Here, the normal mode indicates an operating state in which the user terminal 6 is activated and the user U can operate the keyboard and mouse based on the display image displayed on the display device of the user terminal 6. The display device off mode indicates an operating state in which the power of the display device of the user terminal 6 is turned off and the power consumed by the display device is reduced to save power. The sleep mode is an operating state in which only the devices necessary for restarting are operated in the devices constituting the user terminal 6 and the power of the display device is turned off, and further the power saving of the user terminal 6 is performed. Show. The shutdown indicates a state in which all devices in the user terminal 6 are turned off and only restart is required to shift to the normal mode.

Returning to FIG. 1, the position detection device 2 detects a position where the user U exists, and includes a user position detection unit 21 and an approach advance confirmation unit 22.
The user U carries the transceiver 8 in order to detect the position where the user U exists. For example, the transceiver 8 may be an IC card, an RF tag, or an indoor GPS terminal. In this embodiment, an example using indoor GPS is shown. The transmitter / receiver 8 is an indoor GPS terminal, receives radio waves from the transmitter 7 at a constant cycle (for example, one minute cycle), and transmits transmitter identification information of the transmitter 7 and terminal owner identification information for identifying itself. The user position information is transmitted to the position detection device 2. Here, when the transmitter / receiver 8 periodically receives a radio signal, the transmitter 7 is not arranged around the transmitter 8, and any transmitter 7 In the case where the wireless signal cannot be received, the dummy transmitter identification information that has been written and stored in the internal storage unit in advance is used as the user position information. This is the same information as the dummy transmitter identification information in the table.

  This terminal owner identification information is identification information for identifying the user U who carries this transceiver 8 as already described. Further, the terminal owner identification information is written and stored in advance in a storage unit provided inside the transceiver 8. Each time the transmitter / receiver 8 receives a radio signal from the transmitter 7, the transceiver 8 reads terminal owner identification information from the internal storage unit. Further, the transmitter / receiver 8 transmits the terminal owner identification information read from the internal storage unit to the position detection device 2 together with the transmitter identification information included in the radio signal.

The user position detection unit 21 extracts terminal owner identification information from user position information transmitted from the transceiver 8. The user position detection unit 21 reads a terminal identification number corresponding to the extracted terminal owner identification information from the user table of the user database 5.
Further, the user position detection unit 21 extracts transmitter identification information from the user position information, and reads terminal identification information corresponding to the extracted transmitter identification information from the position table of the position database 4.

  The user position detection unit 21 determines whether or not the user terminal 6 is operated by the user based on whether or not the terminal identification information read from each of the user table and the position table matches with the same user position information. I do. That is, the user position detection unit 21 determines (detects) that the user exists in the vicinity of the user terminal 6 when the terminal identification information read from each of the user table and the position table matches. On the other hand, when the terminal identification information read from each of the user table and the position table does not match, the user position detection unit 21 determines (detects) that the user does not exist in the vicinity of the user terminal 6.

  The approach advance confirmation unit 22 receives the entry advance signal from the transceiver 8, and extracts the terminal owner identification information included in the entry advance signal. Here, the transceiver 8 is a position where a person in and out of a specific area, for example, the entrance / exit of the room where the user terminal 6 operated by the user U is arranged, or the building where the user terminal 6 operated by the user U is arranged. When an approach radio signal is received from an approach transmitter (not shown) that detects the approach or advance of the user U who places the transceiver 8 provided at the doorway, the position detection device 2 is stored in the internal storage unit. An approach advance signal to which the stored terminal owner identification information is added is transmitted.

  The approach advance confirmation unit 22 searches the user table of the user database 5 for terminal identification information corresponding to the terminal owner identification information, and confirms the state of the entry flag. Here, if the entry flag is “1” when the entry advance signal is supplied, the entry advance confirmation unit 22 has already entered the specific area and the entry advance signal has been newly supplied. Assuming that the user U advances from a specific area, an advance signal is output to the terminal mode control device 3. Moreover, the approach advance confirmation part 22 changes the approach flag in the user table of the user database 5 from “1” to “0” when outputting the advance signal.

  Further, when the approach radio signal is supplied, if the approach flag is “0”, the approach advance confirmation unit 22 does not exist in the specific area and a new approach advance signal is supplied. Is entering a specific area, an entry signal is output to the terminal mode control device 23. Moreover, the approach advance confirmation part 22 changes the approach flag in the user table of the user database 5 from “0” to “1” when outputting this approach signal.

  The terminal mode control device 3 is configured to change the operation state of each user terminal 6 under the management of the user terminal management system 1 to the normal mode, the display device off mode for turning off the power of the display device of the user terminal 6, the sleep mode, and the shutdown. Control to set one of the modes is performed. The terminal mode control device 3 includes a user terminal operation detection unit 31, a mode control unit 32, a telephone state detection unit 33, and a timer 34. The timer 34 is provided for each user U, that is, for each terminal owner identification information.

  The user terminal operation detection unit 31 inputs an elapsed time since the user last operated the user terminal 6 from each of the user terminals 6. Here, the user terminal 6 counts the elapsed time since the user no longer operates the keyboard or mouse of the user terminal 6, for example, and adds the no-operation count value as the count result to its own terminal identification information. And output to the user terminal operation detection unit 31. Further, when the no-operation count value supplied from the user terminal 6 exceeds a preset determination value, the user terminal operation detection unit 31 is a user corresponding to the terminal identification information added to the no-operation count value. It is determined that the terminal 6 is not operated. The user terminal operation detection unit 31 adds the terminal identification information of the user terminal 6 to the user operation information indicating whether or not the user terminal 6 is operated, and outputs it to the mode control unit 32. Based on this user operation information, the mode control unit 32 determines whether or not each of the user terminals 6 is operated.

  The telephone state detection unit 33 manages an IP (Internet Protocol) telephone terminal to determine whether or not a telephone terminal that is normally used by the user and is located near the user terminal 6 operated by the user is in use. The telephone identification information of the telephone terminal is transmitted to and inquired from a DHCP (Dynamic Host Configuration Protocol) server (not shown) or the like, and the usage state of the telephone terminal is acquired as user call information. Here, the telephone identification information is, for example, the telephone number of the telephone terminal, the MAC address of the telephone terminal, or the like. Further, the telephone state detection unit 33 determines whether or not the telephone terminal is in use based on the user call information indicating the telephone usage status supplied as a result of the inquiry from the DHCP server. Here, the telephone state detection unit 33 searches for the terminal identification information corresponding to the telephone identification information in the user table of the user database 5 using the telephone identification information included in the user call information, and uses the terminal identification information as the terminal identification information. The corresponding user terminal 6 is specified.

  The mode control unit 32 determines that the user U is not in the vicinity of the user terminal 6, the user terminal 6 is not operated, and the user who operates the user terminal 6 is not in a call (during a call). At the detected timing, the timer 34 is reset and the timer 34 starts counting time. In addition, the mode control unit 32 stores the first set time, the second set time, and the third set time in advance in the internal storage unit. Here, the relationship between the time lengths of the first setting time, the second setting time, and the third setting time is such that the first setting time <the second setting time <the third setting time.

  The first set time is that the user terminal 6 has been operated by this time after the timer 34 starts counting, or that the user operating the user terminal 6 is in a call. When any of the above is not detected by the determination result, the time range in which the power of the display device of the user terminal 6 is turned off, that is, the transition from the normal mode to the display device off mode is shown. When the count value of the timer 34 exceeds the first set time, the mode control unit 32 changes the operating state of the corresponding user terminal 6 from the normal mode to the display device off mode, and in the user table of the user database 5, The mode flag corresponding to the terminal identification information of the user terminal 6 in the display device off mode is rewritten from “0” to “1”.

  In addition, the second set time indicates that the user terminal 6 has been operated by this time after the timer 34 starts counting, or that the user operating the user terminal 6 is in a call. When either one is not detected by the determination result, the time range in which the user terminal 6 is shifted from the display device off mode to the sleep mode is shown. When the count value of the timer 34 exceeds the second set time, the mode control unit 32 changes the operating state of the corresponding user terminal 6 from the display device off mode to the sleep mode, and in the user table of the user database 5, The mode flag corresponding to the terminal identification information of the user terminal 6 in the sleep mode is rewritten from “1” to “2”.

  Further, the third set time indicates that the operation of the user terminal 6 is performed by this time after the timer 34 starts counting, or that the user operating the user terminal 6 is in a call. When either is not detected by the determination result, the time range in which the user terminal 6 is shifted from the sleep mode to the shutdown is shown. When the count value of the timer 34 exceeds the third set time, the mode control unit 32 changes the operating state of the corresponding user terminal 6 from the sleep mode to the shutdown and sets the shutdown in the user table of the user database 5. The mode flag corresponding to the terminal identification information of the user terminal 6 is rewritten from “2” to “3”.

  Further, the mode control unit 32 confirms that the operation of the user terminal 6 is performed after the count value of the timer 34 exceeds the first setting time or the second setting time and before the third setting time, or When it is detected that the user operating the user terminal 6 is talking on the telephone terminal, the operating state of the user terminal 6 is shifted from the display device off mode or the sleep mode to the normal mode. Here, the mode control unit 32 subtracts the count value of the timer 34 from the first set time, and obtains the difference between the first set time and the count value of the timer 34 periodically (for example, every second). The difference is displayed on the display device of the user terminal 6. Thereby, the user U confirms the remaining time until the operating state of the user terminal 6 used by the user U shifts from the normal mode to the display device off mode as a countdown on the display device of the user terminal U. Can do.

Next, the operation of the user terminal management system 1 according to the present embodiment will be described using FIG. 1 and FIG. FIG. 4 is a flowchart showing an operation example of management of the user terminal 6 of the user terminal management system 1 according to the present embodiment. 4 is performed for each user terminal 6, that is, for each user U. As an initial state, in the user table of the user database 5, the entry flag corresponding to each terminal identification information of the user terminal 6 under the management of the user terminal management system 1 is “0”, and the mode flag is “3”. It has become.
Step S1:
The entry / exit confirmation unit 22 detects whether an entry / exit signal has been supplied from the transceiver 8 carried by the user U.
Here, when the approach advance signal is supplied from the transceiver 8, the approach advance confirmation unit 22 advances the process to step S2. On the other hand, when the approach advance signal is not supplied from the transceiver 8, the process of step S1 is repeated. .

Step S2:
When the entry advance signal is supplied from the transceiver 8 carried by the user U, the entry advance confirmation unit 22 extracts the terminal owner identification information of the user U from the entry advance signal.
And the approach advance confirmation part 22 detects the state of the approach flag corresponding to the extracted terminal owner identification information in the user table of the user database 5.
At this time, since the entry flag is “0”, the entry advance confirmation unit 22 has entered the specific area (for example, a room or a building in which the user terminal 6 used by the user U is located). And an entry signal including terminal owner identification information is output to the mode control unit 32. Further, the entry advance confirmation unit 22 rewrites the entry flag corresponding to the terminal owner identification information from “0” to “1” in the user table of the user database 5.

Next, the mode control unit 32 extracts terminal identification information corresponding to the terminal owner identification information from the user table of the user database 5.
And the mode control part 32 starts the user terminal 6 corresponding to this extracted terminal identification information from shutdown, makes it operate | move as a normal mode, and advances a process to step S3. The activation here is performed by a power source operation of the user terminal 6 performed via a LAN (Local Area Network), for example, a function such as Wake on LAN (registered trademark). Further, the mode control unit 32 rewrites the mode flag corresponding to the terminal owner identification information of the entered user U from “3” to “0” in the user table of the user database 5.

Step S3:
Next, when it is confirmed that the user U has entered the specific area, the mode control unit 32 resets the timer 34 corresponding to the terminal owner identification information of the user U, and sets the count value of the timer 34 to “ 0 ", the count is started, and the process proceeds to step S4.

Step S4:
Next, the user position detection unit 21 detects whether or not the user U who has entered is near the user terminal 6 operated by the user, based on the user position information transmitted from the transmitter 7.
Here, the user position detection unit 21 reads the transmitter identification information and the terminal owner identification information from the user position information from the transmitter 7.

Step S5:
Next, the user position detection unit 21 reads terminal identification information corresponding to the read transmitter identification information from the position table of the position database 4.
Then, the user position detection unit 21 reads terminal owner identification information corresponding to the read terminal identification information from the user table of the user database 5.
Next, the user position detection unit 21 determines whether or not the terminal owner identification information read from the user table of the user database 5 matches the terminal owner identification information extracted from the user position information.

At this time, when the terminal owner identification information read from the user table of the user database 5 matches the terminal owner identification information extracted from the user position information, the user position detection unit 21 determines that the user U who has entered the specific area It is determined that the user terminal 6 operated by the user is in the vicinity of the user terminal 6, that is, is present, and the process proceeds to step S6.
On the other hand, when the terminal owner identification information read from the user table of the user database 5 does not match the terminal owner identification information extracted from the user position information, the user position detection unit 21 determines that the user U who has entered the specific area It is determined that the user terminal 6 is not in the vicinity of the user terminal 6, that is, is not present, starts the timer 34 counting process corresponding to the terminal owner identification information of the user U who has entered this specific area, and the process is stepped. Proceed to S9. Thereby, even if it is determined that the user position detection by the user position detection unit 21 is an error and it is determined that the user U is not in the vicinity of the user terminal 6, the user is in a call using the telephone terminal corresponding to the user terminal 6. For example, whether or not the user U is in the vicinity of the user terminal 6 can be detected.

Step S6:
Next, the user terminal operation detection unit 31 compares the no-operation count value transmitted from the user terminal 6 with the determination value stored in advance in the internal storage unit, and the user terminal 6 is It is confirmed whether or not it is operated by U.

Step S7:
Next, when the no-operation count value transmitted from the user terminal 6 exceeds the determination value, the user terminal operation detection unit 31 determines that the user terminal 6 is not operated, and the mode control unit 31 , User operation information indicating that the user terminal 6 has not been operated by the user U (terminal identification information is added) is output. Based on this user operation information, the mode control unit 31 proceeds to step S7 assuming that the user terminal 6 is not operated by the user U.
On the other hand, when the no-operation count value transmitted from the user terminal 6 is equal to or smaller than the determination value, the user terminal operation detection unit 31 determines that the user terminal 6 is operated, and the user terminal 6 is operated by the user U. Is output to the mode control unit 31. With this user operation information, the mode control unit 31 advances the process to step S3, assuming that the user terminal 6 is operated by the user U.

Step S8:
Next, the telephone state detection unit 33 reads the telephone identification information corresponding to the terminal owner identification information of the entered user U from the user table of the user database 5.
Then, the telephone state detection unit 33 adds the read telephone identification information and makes an inquiry about the usage status of the telephone terminal to the DHCP server.
Thereby, the telephone state detection unit 33 obtains the user call information indicating the usage status of the telephone terminal of the user U corresponding to the telephone identification information added to the transmitted inquiry from the DHCP server as a response to the inquiry.

Step S9:
Next, the telephone state detection unit 33 uses the telephone terminal when the usage status of the telephone terminal (the telephone terminal of the user U) of the telephone identification information inquired indicated in the user call information obtained as a response to the inquiry from the DHCP server. If yes (during a call), the process proceeds to step S3.
On the other hand, if the telephone terminal of the queried telephone identification information indicated in the user call information obtained as a response to the inquiry from the DHCP server is not busy, the telephone state detection unit 33 advances the process to step S10.

Step S10:
Next, the mode control unit 32 reads the count value of the timer 34 corresponding to the entered user U, and determines whether or not this count value has exceeded the first set time stored in advance in the internal storage unit. Do.
And the mode control part 32 advances a process to step S4, when the count value of the timer 34 does not exceed 1st setting time.
On the other hand, if the count value of the timer 34 exceeds the first set time, the mode control unit 32 advances the process to step S11.

Step S11:
Next, the mode control unit 32 determines whether or not the user terminal 6 corresponding to the entered user U is in the display device off mode in which the display device of the user terminal 6 itself is turned off.
Here, the mode control unit 32 reads the mode flag data corresponding to the terminal identification information of the user terminal 6 from the user table of the user database 5.
At this time, if the read mode flag is not “1”, that is, “0”, and the user terminal 6 corresponding to the entered user U is not in the display device off mode, the mode control unit 32 performs the process. Proceed to S12.
On the other hand, if the read mode flag is “1”, that is, if the user terminal 6 corresponding to the user U who has entered the read mode is in the display device off mode, the mode control unit 32 advances the process to step S13. .

Step S12:
Next, the mode control unit 32 outputs a control signal indicating that the power of the display device is turned off to the corresponding user terminal 6, and the terminal identification of the user terminal 6 in the user table in the user database 5. The mode flag corresponding to the information is rewritten from “0” to “1”.
Further, when a control signal for turning off the power is supplied, the user terminal 6 turns off the power of its own display device, and shifts the operating state from the normal mode to the display device off mode.

Step S13:
Next, the mode control unit 32 reads the count value of the timer 34 corresponding to the entered user U, and determines whether or not the count value exceeds a second set time stored in advance in the internal storage unit. Do.
And the mode control part 32 advances a process to step S4, when the count value of the timer 34 is not over 2nd setting time.
On the other hand, if the count value of the timer 34 exceeds the second set time, the mode control unit 32 advances the process to step S14.

Step S14:
Next, the mode control unit 32 determines whether or not the user terminal 6 corresponding to the entered user U is in the sleep mode.
Here, the mode control unit 32 reads the mode flag data corresponding to the terminal identification information of the user terminal 6 from the user table of the user database 5.
At this time, when the read mode flag is not “2”, that is, when the mode flag is “1” and the user terminal 6 corresponding to the entered user U is not in the sleep mode, the process goes to step S15. Proceed.
On the other hand, when the read mode flag is “2”, that is, when the user terminal 6 corresponding to the user U who has entered the read mode is in the sleep mode, the mode control unit 32 advances the process to step S16.

Step S15:
Next, the mode control unit 32 outputs a control signal indicating that the sleep mode is set to the corresponding user terminal 6 and a mode corresponding to the terminal identification information of the user terminal 6 in the user table of the user database 5. The flag is rewritten from “1” to “2”.
Further, when a control signal for turning off the power is supplied, the user terminal 6 shifts the operating state from the display device off mode to the sleep mode.

Step S16:
Next, the mode control unit 32 reads the count value of the timer 34 corresponding to the entered user U, and determines whether or not the count value exceeds the third set time stored in advance in the internal storage unit. Do.
And the mode control part 32 advances a process to step S4, when the count value of the timer 34 does not exceed 3rd setting time.
On the other hand, if the count value of the timer 34 exceeds the third set time, the mode control unit 32 advances the process to step S17.

Step S17:
Next, the mode control unit 32 outputs a control signal indicating that the corresponding user terminal 6 is to be shut down, and a mode flag corresponding to the terminal identification information of the user terminal 6 in the user table in the user database 5. Is rewritten from “2” to “3”.
Further, when a control signal for turning off the power is supplied, the user terminal 6 shifts itself from the operating state of the sleep mode to the shutdown mode.

Step S18:
Next, the mode control unit 32 makes an inquiry to the user terminal 6 that is shut down, and determines whether or not the user U has been controlled to start.
In response to the inquiry to the user terminal 6 described above, the mode control unit 32 determines whether or not the user terminal 6 has been restarted based on the information indicating whether or not the user terminal 6 has been started. .
At this time, when the user terminal 6 is restarted and enters the normal mode, the mode control unit 32 sets the mode flag corresponding to the terminal identification information of the user terminal 6 from “3” in the user table of the user database 5. Rewrite to “0”. After rewriting the mode flag, the mode control unit 32 advances the process to step S3.
On the other hand, if the user terminal 6 is in the shutdown mode without being restarted, the mode control unit 32 advances the process to step S19.

Step S19:
Next, the entry / exit confirmation unit 22 detects whether an entry / exit signal is supplied from the transceiver 8 carried by the user U.
Here, when the approach advance signal is supplied from the transceiver 8, the approach advance confirmation unit 22 advances the process to step S20. On the other hand, when the entry advance advance signal is not supplied from the transceiver 8, the process advances to step S18. .

Step S20:
Next, when an approach advance signal is supplied from the transceiver 8 carried by the user U, the approach advance confirmation unit 22 extracts the terminal owner identification information of the user U from the entry advance signal.
And the approach advance confirmation part 22 detects the state of the approach flag corresponding to the extracted terminal owner identification information in the user table of the user database 5.
At this time, since the entry flag is “1”, the approach advance confirmation unit 22 determines that the user U has advanced from the specific area because the user U already exists in the specific area. And the approach advance confirmation part 22 rewrites the approach flag corresponding to this terminal owner identification information from "1" to "0" in the user table of the user database 5, and advances the process to step S1.

That is, when the user U is working at a desk where the user terminal 6 and the telephone terminal are installed, when the user U is talking using the telephone terminal, the display screen of the user terminal 6 is There may be a case where a call is being made while displaying materials and e-mails used for business and checking these. Therefore, when the user U is talking, it can be considered that the user terminal 6 is being used even if the user terminal 6 is not operated.
Therefore, according to this embodiment described above, the user position information indicates a state that does not exist in the vicinity of the user terminal 6 operated by the user, the user operation information indicates a state that the user is not operating, and the user call information It is determined that the user U is not really using the user terminal 6 only when the user shows a state where the user is not talking. For this reason, according to the present embodiment, it is possible to immediately detect the case where the user does not really use the user terminal 6, and to immediately switch the user terminal 6 to energy-saving in order to shift to the display device off mode. You can enter mode.
