Embodiment 1. FIG.
A first embodiment of the present invention will be described below with reference to the drawings.

  FIG. 1 is an explanatory diagram illustrating an example of a configuration of a power saving determination control system according to the first embodiment.

  The power saving control system shown in FIG. 1 includes a person position information acquisition unit 111, an OA device power saving state determination unit 112, an OA device operator registration database (DB) 121, a power saving transition area registration DB 122, and a person position. An information registration DB 123 and cameras 301 to 303 are provided. The person position information acquisition unit 111 is connected to the cameras 301 to 303 and the person position information registration DB 123. The OA device power saving state determination unit 112 is connected to the OA device operator registration DB 121, the power saving transition area registration DB 122, and the person position information registration DB 123. The cameras 301 to 303 are connected to the person position information acquisition unit 111 via a communication network 200 such as the Internet. Although three cameras 301 to 303 are illustrated in FIG. 1, any number of cameras may be provided.

  In the power saving control system shown in FIG. 1, the OA device 501 used by the operator 601 is connected to the OA device power saving state determination unit 112 via the communication network 200. In FIG. 1, one OA device 501 is illustrated, but any number of OA devices may be connected to the OA device power saving state determination unit 112.

  The OA device operator registration DB 121 is a database for registering OA devices and their operators.

  The power saving transition area registration DB 122 is a database for registering information on a power saving transition area (hereinafter referred to as power saving transition information). The power saving transition area is an area determined by position coordinates (X coordinate and Y coordinate). In the power saving transition area registration DB 122, the position coordinate range indicating the area of the power saving transition area, the power saving state corresponding to the power saving transition area, and the residence time until the transition (hereinafter referred to as transition judgment residence time) are registered. Is done.

  For example, when the position coordinates of the area before the copier are x1 ≦ X ≦ x2 and y1 ≦ Y ≦ y2, the power saving transition area “before copying machine” is registered in the power saving transition area registration DB 122 as shown in FIG. 2 (Example 1), “x1 ≦ X ≦ x2, y1 ≦ Y ≦ y2” is set in the position coordinate range. Further, when the operator is in front of the copier, it is expected that the absence time is short, so “display OFF” that requires a short time to return to the operating state is set to the power saving state. In addition, the transition determination residence time is set for how long after the operator enters the power saving transition area, the OA device is shifted to the power saving state.

  In the example shown in FIG. 2, the transition determination residence time is set in units of seconds, but may be in arbitrary units such as minutes. Further, x1 to x6 and y1 to y6 that specify the range of the power saving transition area, and the power saving state and the transition determination residence time corresponding to the power saving transition area can be arbitrarily set by the user of the power saving control system. is there. FIG. 2 illustrates three power saving transition areas “in front of the copy machine”, “conference room”, and “going out”, but how many pieces of power saving transition information are registered in the power saving transition area registration DB 122. It may be. The position coordinate range corresponding to “outing” is, for example, a range near the entrance / exit.

  The person position information registration DB 123 is a database for registering the position coordinates of the operator. Further, the position coordinates of the operator's seat are stored.

  The person position information acquisition unit 111 acquires the images of the cameras 301 to 303, acquires the position coordinates of the operator of the OA device from the acquired image, and registers the position coordinates of the operator in the person position information registration DB 123. In addition, the person position information acquisition unit 111 identifies the operator from the coordinates at which the operator is seated. For example, when a person seated in a video taken by the cameras 301 to 303 is seated, if the seated coordinates match the coordinates of the seat of the operator 601 stored in the person position information registration DB 123, the person is designated as the operator 601. Judge that there is.

  The OA device power saving state determination unit 112 periodically acquires the position coordinates of the operator from the person position information registration DB 123, and the acquired position coordinates and the power saving transition area registered in the power saving transition area registration DB 122. Based on the position coordinate range, it is determined whether the operator has entered the power saving transition area. When a plurality of power saving transition areas are registered in the power saving transition area registration DB 122, the OA device power saving state determination unit 112 determines whether an operator has entered any of the registered transition areas. . Further, the OA device power saving state determination unit 112 sends a command for shifting to the power saving state corresponding to the power saving transition area to the OA device.

  The OA device power saving state determination unit 112 and the person position information acquisition unit 111 can be realized by a microcomputer or the like that operates according to a program.

  The cameras 301 to 303 are installed in each power saving transition area and photograph the power saving transition area.

  Next, the operation of this embodiment will be described with reference to FIG. 1, FIG. 2, and FIG. Here, a case where the operator 601 of the OA device 501 shown in FIG. 1 moves from his / her seat to the power saving transition area A shown in FIG. 2 is taken as an example.

  FIG. 3 is a flowchart showing the operation of the power saving control system according to the first embodiment of the present invention.

  The administrator of the power saving control system registers the OA device 501 and its operator 601 in advance in the OA device operator registration DB 121 (step S301). Further, the position coordinates of the seat of the operator 601 are registered in the person position information registration DB 123.

  In addition, the user of the power saving control system registers in advance the power saving transition area A in which the power saving state is set to the power saving state a and the transition determination residence time is set to n seconds in the power saving transition area registration DB 122 (step S302). ).

  When the operator 601 is seated in his / her seat, the person position information acquisition unit 111 acquires the position coordinates where the operator 601 is seated from the images taken by the cameras 301 to 303, and the person seated from the acquired coordinates is the operator. 601 is determined (step S303).

  Next, the person position information acquisition unit 111 starts a process of acquiring the position coordinates of the operator 601 from the video generated by the cameras 301 to 303 photographing the space and registering the position coordinates in the person position information registration DB 123 (step S304). ).

  The OA device power saving state determination unit 112 periodically refers to the person position information registration DB 123 to check whether or not the position coordinate range of the operator 601 is included in the position coordinate range of the power saving transition area A (step). S305).

  When the position coordinate range of the operator 601 is included in the position coordinate range of the power saving transition area A (Yes in step S305), the OA device power saving state determination unit 112 indicates that the operator 601 is in the power saving transition area A. Judge that entered. Then, the OA device power saving state determination unit 112 checks whether or not the elapsed time since the operator 601 entered the power saving transition area A has reached the transition determination residence time n seconds (step S306).

  When the position coordinate range of the operator 601 is not included in the position coordinate range of the power saving transition area A (No in step S305), the OA device power saving state determination unit 112 resets the elapsed time and performs the process of step S305. Return to.

  When the elapsed time has reached n seconds in step S306 (Yes in step S306), the OA device power saving state determination unit 112 refers to the OA device operator DB 121 and determines the OA device used by the operator 601. Identify. The OA device power saving state determination unit 112 sends a command for shifting to the power saving state a via the network to the OA device 501 used by the operator 601 (step S307). When receiving the command from the OA device power saving state determination unit 112, the OA device 501 shifts to the power saving state a.

  If the elapsed time has not reached n seconds in step S306 (No in step S306), the process returns to step S305, and the OA device power saving state determination unit 112 repeats the processes in and after step S305.

  As described above, the OA device can be shifted to the power saving state in accordance with the area where the operator is located. Further, since the power saving state of the power saving transition area can be set, the OA device can be shifted to the optimum power saving state. For example, a power-saving state with quick return is set for areas where leaving seats are expected to be short, and a power-saving state with low power consumption is set for areas where leaving seats are expected to be long. By doing so, it is possible to achieve both improvement of the convenience for the operator and power saving of the OA device.

  In addition, since the position information of the operator is acquired using the camera, even when the layout of the area where the cameras 301 to 303 are installed changes, the power saving transition area registered in the power saving state area registration DB 122 is changed. It is only necessary to reset the position coordinates, the power saving state, and the transition determination residence time.

  Note that the power saving transition information may include an execution command corresponding to the power saving transition area. According to such a configuration, if a security patch application command or data backup command is set as an execution command corresponding to the power saving transition area, security patch application or data backup can be performed in the operator's location area or remote location. It can be executed according to the seating time. For example, in an office or the like, while an operator has a meeting in a conference room, a security patch can be applied to an OA device used by the operator or data can be backed up.

  In addition, in order to track the operator 601 without interruption from when the operator 601 is seated to when the operator 601 moves to the power saving transition area, the cameras 301 to 303 continuously acquire the position information of the operator. It is desirable to prepare and install as many units as possible.

  The OA device operator registration DB 121, the power saving transition area registration DB 122, and the person position information registration DB 123 are connected to the person position information acquisition unit 111 or the OA device power saving state determination unit 112 via a communication network such as the Internet. It may be.
