JPH11249765A - Terminal power source control method based on entering/ leaving management - Google Patents

Abstract

PROBLEM TO BE SOLVED: To control the power source of a terminal to be used while being linked with the entering/leaving management of a terminal user. SOLUTION: A storage means is provided for storing the entering/leaving management of a terminal user and the correspondence between the terminal user and the terminal. Besides, a terminal power source managing table 13 is prepared for managing the power supply condition (utilization condition) of the terminal in use. Thus, at the time of entering a room, the power source of the terminal related to the user is turned on and at the time of leaving the room, the power source of the related terminal is turned off. When utilizing one terminal by plural persons, it is judged while referring to the terminal power source managing table 13 whether it is necessary to newly turn on the power source of the terminal or the power source can be already turned off.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal power control method based on terminal user entry / exit management, and more particularly to a storage means for storing a correspondence between a terminal user and a terminal.
The present invention relates to a terminal power control method based on entry / exit management suitable for efficiently controlling the power supply of a user terminal through entry / exit management using a personal IC card or the like.

[0002]

2. Description of the Related Art In order to control the power of a terminal, in addition to power on / off by directly operating a switch of the terminal by a user, a power supply control device for performing power on / off by a remote power control command, time, and the like. There is a power supply control device that turns on and off the power supply by scheduling using a power supply.

[0003] However, in this power supply control device, it is possible to control all the terminals to be controlled or to control the terminals according to time, but the user cannot control the terminals.

[0004] Entrance / exit management is performed by using an entrance / exit management sensor, such as carrying an IC card storing information for identifying an employee such as an employee number or a card (ID card or IC card) dedicated to entrance / exit management. There is a device that reads information for identifying an entering / leaving person and manages the entering / leaving status.

The purpose of this entry / exit management is to manage whether the user has the right to enter a room or a building, whether or not the user is in a room or a building, or whether or not he or she has left a room or a building. Control the room, but it only controls the entire room and building facilities,
At present, the control target is not changed even in the same room by the user. In some cases where buildings are managed, facilities in the buildings are controlled on a room-by-room basis, but still only control is performed on a large unit of room.

[0006]

If the above-mentioned prior art is used, it is possible to directly control the power of the terminal or to remotely control the power by scheduling.

[0007] However, the method of directly controlling the power supply of the terminal has a problem that it takes a long time to start up the terminal and cannot be used immediately, and there is a problem that the user goes home without forgetting to turn off the power supply of the terminal. In remote power control, the terminal can be used immediately when the user comes close to the terminal by remotely controlling the power of the terminal.However, when multiple users share the terminal, another terminal is already used. Issue a power-on command even though the user has turned on the power, or issue a power-off command even if another user is still using the terminal and give it to another user There is a problem of causing trouble.
In power control by scheduling, power is turned on or off for all terminals scheduled at a certain time, power is turned on to terminals that are not necessary for the user, and power to terminals is turned off during use. There's a problem.

[0008] An object of the present invention is to provide a method for controlling the power supply of only a terminal necessary for a terminal user by associating the terminal user with the terminal by utilizing entry / exit management using an individual IC card or the like. Is to provide.

[0009]

In order to achieve the above object,
In the present invention, a storage unit for storing the correspondence between the terminal user and the terminal is provided for the entry / exit management. The power supply control means when the user enters the room searches the storage device storing the correspondence between the terminal user and the terminal when the entrance / exit management sensor confirms the user's entry, and corresponds to the user who entered the room. It issues a control command to turn on the terminal and turns on the terminal. When the user leaves the room, when the entry / exit management sensor confirms that the user has left the room, the storage device that stores the correspondence between the terminal user and the terminal is searched and the terminal corresponding to the user who left the room is searched. Issue a power-off control command to power off the terminal.

[0010] Thus, the user can use the terminal or turn off the power of the terminal when the user comes near the terminal only by entering and leaving the room.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.

First, the configuration and operation of the overall system on which the present invention is premised will be outlined with reference to FIG.

In FIG. 1, reference numeral 11 denotes an entrance / exit management sensor, which is attached to an entrance (16). The entry / exit management sensor is an ID card or IC owned by an individual
Manage the entry and exit of individuals with cards and the like. This ID card or IC card stores an identification number for identifying an individual. In the case of entering and leaving a room as an example, first, in the case of entering a room, for example, "A" (17) enters the room, and when an IC card or an ID card (18) is passed through the entrance / exit management sensor (11), a card is entered. From the entry number, the entry / exit status of "Mr. A" of the entry / exit management device (12) is changed to "Making", the information of "Mr. A" is read from the association table (13), and the value of the "Min. 2 'is sent to the power control device (14). The power control device (14) reads the terminal power management table (15) from the received information,
A terminal name and user information are recorded, and a signal is sent to turn on the power of the terminal 2. The terminal 2 (28) turns on the power from the received signal. Next, when leaving, 'B
To explain with Mr. (20), since Mr. B (20) leaves, the IC card or I
When the D card (21) is passed, the entry / exit status of "Mr. B" of the entry / exit management device (12) is changed to "leaving" from the card number, and the information of "Mr. B" is obtained from the correspondence table (13). Is read, and the value “terminal 1” of the correspondence table is sent to the power supply control device (14). The power control device (14) reads the terminal power management table (15) from the received information, deletes the terminal name and the user information, and outputs a signal for turning off the power of the terminal 1 (in this case, it depends on the terminal. A termination signal and a power-off signal of the OS managing the terminal are sent.)
To the terminal 1. The terminal 1 (27) turns off the power from the received signal. When the OS termination signal is received, it goes without saying that the power is turned off after the OS termination.

FIG. 2 shows the data structure of the association table. 121 stores the name of a user who uses the terminal, and 122 stores the name of a terminal that performs power control. As an example, in 123, the user 'A' uses the terminal name 'terminal 2' and controls the power of 'terminal 2' when 'A' enters or leaves. At 124, the user 'C' uses the terminal name 'terminal 1, terminal 2, terminal 3' and controls the power of 'terminal 1, terminal 2, terminal 3' when 'C' enters or leaves. This table is created in advance.

FIG. 3 shows the data structure of the terminal power management table. 131 stores the name of the terminal that is being used (power is on), and 132 stores a list of users who use the terminal. As an example, in 133, the terminal name is used, and in "terminal 1", a user list "Mr. B" and "Mr. E" enter and use the room. In 134, the terminal name 'terminal 2' is entered and used by the user list 'A'. This table does not need to be created in advance, and is changed each time the power is turned on / off. Further, for example, since the terminal 4 is not currently in the table, when a user who uses the terminal 4 appears, the terminal 4 adds information of the terminal 4 and sends a power-on signal. In the case of the terminal 2, even if a new user who uses the terminal 2 appears, the information of the terminal 2 is already present.
The power ON signal is not sent. When 'A' using the terminal 2 leaves, all the users are deleted, so that all the information of the terminal 2 is deleted and a signal of the power supply “OFF” is sent. Thus, it is determined whether to turn on the terminal based on the information in this table.

FIG. 4 shows a processing flow when a user enters a room. If the user enters the room, steps 400 and 41
It is executed in the middle. In step 420, the entry / exit management device is referred to from the identification number of the card used for entering the room, and in step 430, the user name registered in advance is
The association table is read, and the terminal name to be used is acquired. Next, step 440 is executed. In step 450, the terminal power management table of the power supply control device is referred to by using the terminal name as a key. If the terminal name is registered, step 451 is executed. If the terminal name is not registered, steps 452 and 453 are executed. I do. Step 451 is a process in a case where the terminal is already turned on. In this case, a user name is added to the table to indicate that the number of users has increased. Steps 452 and 453 are processing when the power of the terminal has not been turned on yet. In this case, the terminal name and the user name to be newly used are added. Further, a power-on signal is sent to the terminal having the same name as the terminal to turn on the terminal. Upon receiving this signal, the terminal turns on the power.

FIG. 5 shows a processing flow when the user leaves the room. If the user leaves, steps 500, 51
Executed as 0. In step 520, the entry / exit management device is referred from the identification number of the card used for exit, and in step 530, the user name registered in advance is
The association table is read, and the terminal name to be used (in this case, used) is acquired. Next, step 540 is executed. In step 550, the terminal power management table of the power supply control device is referred to by using the terminal name as a key. If the terminal name is registered, step 551 is performed. If the terminal name is not registered, steps 552 and 553 are performed. Execute. Step 551 is a process when the user of the terminal is gone. In this case, the terminal name and the user name in the table are deleted to indicate that the user is gone. Further, in order to turn off the power of the terminal, a power-off signal is sent to the terminal having the same name as the terminal. Alternatively, the OS termination signal and the power-off signal are sent together. On the terminal side,
When this signal is received, the power is turned off. Alternatively, the OS is terminated, and then the power is turned off. Step 552, 5
53 is a process when there is still a user. In this case, the user name is deleted.

[0018]

According to the present invention, after the terminal user goes to the side of the terminal and turns on the power of the terminal, the terminal can be used without waiting for the terminal to be activated.
