Description

  The present invention relates to a guard system that can suitably ensure various security in a workspace.

  In a general office, it is customary to allocate a work space for each worker and arrange furniture such as desks, cabinets, and wagons used by the workers. A lock is provided on a fixture used in such an office. Workers can appropriately lock desk drawers, cabinets, wagons, etc., and deter unauthorized removal of documents and other items stored in them.

Many of the forms of locks mounted on office furniture are mechanical ones that insert a key to drive a cylinder and a dead bolt, but as disclosed in the following patent document, unlocking or unlocking can be performed by inputting a password. There are also existing fixtures equipped with electric locks that can be locked.
JP 05-195659 A

  Of course, the mechanical lock can be unlocked only by the person who has the key. Therefore, when there is a need for another worker to use an item stored in a fixture used by the worker when the worker is absent, this is a problem because the worker cannot take it out. Similarly, even an electric lock that is unlocked through the input of a personal identification number can be unlocked only by a person who knows the personal identification number.

  If you want to share the same goods with multiple workers, in other words, if you want multiple workers to be able to unlock one fixture, you can duplicate or distribute the key to these workers in advance I need to know my number. In addition, normally, since there is a one-to-one correspondence between the lock and the key or secret code for unlocking this lock, the number of keys distributed, that is, the number of keys distributed in proportion to the number of fixtures is informed. The number of passwords to be increased also increases. This is not preferable because it leads to an increase in security risk such as key theft and leakage of a password.

  The present invention made in view of the above is intended to realize a work space supervision system that achieves both convenience and security strength.

  In order to solve the above-described problem, in the present invention, as shown in FIG. 1, at least one fixture, article, information processing apparatus, or electronic data that should be restricted from access by a person other than the authorized user is guarded. At least one security means that is attached to each of the fixture, the article, or the information processing device and that exhibits a security function for restricting access to the fixture, the article, the information processing device, or the electronic data. 101, a user having a legitimate authority, a user identification information transmitting unit 102 for transmitting user identification information for identifying the user, and a user for receiving user identification information transmitted from the user identification information transmitting unit 102 Identification information receiving means 103 and user identification information relating to the user, the user identification information When the communication means 103 cannot be received, the control means 104 that activates the security function by the security means 101 and the user identification information related to the user are received when the user identification information receiving means 103 is receiving them. A guard system 1 was constructed comprising a control release means 105 for releasing a security function for the fixture, the article, the information processing apparatus, or the electronic data that is allowed to be accessed in accordance with user identification information. In addition, the restriction of access referred to here is to prevent the use or taking out of fixtures, articles, information processing devices or electronic data to be guarded, and / or to prevent access to these fixtures, etc. say.

  In the supervision system 1 according to the present invention, when a user having a legitimate authority appears in the workspace, and user identification information relating to this user is transmitted and received between the user identification information transmitting means 102 and the user identification information receiving means 103. In addition, the security function for the furniture, articles, information processing apparatus, or electronic data arranged in the workspace is released. Then, when a user having a legitimate authority leaves the workspace and cannot transmit / receive the user identification information related to the user, the security function for the fixtures and the like arranged in the workspace is activated again. In the present supervision system 1, even if there are a plurality of fixtures, articles and information processing devices to be supervised, only one user identification information transmission means 102 may be used as a key for releasing the security function for these. Therefore, by distributing the user identification information transmitting means 102 to each user one by one, each user can cancel the security function for furniture, articles, information processing apparatus or electronic data as necessary. Become. In addition, the range for releasing the security function can be changed in accordance with the user identification information transmitted by the user identification information transmitting means 102. For example, in the case of trying to operate a plurality of fixtures, articles, or information processing devices arranged in a workspace assigned to a certain user, the user who is assigned the workspace (operates in the workspace) For example, the security function can be canceled for all of them, while the security function can be canceled only for some of them by other users. With such a configuration, it is possible to avoid an increase in security risk associated with distributing a plurality of keys to a plurality of users and to provide high convenience.

  It is also a feature of the present invention that the object of custody is not limited to a fixture with a lock mounted. In the guard system according to the present invention, it is possible to directly guard articles or information processing devices that are desired to be protected, and it is possible to save the trouble of putting them in a key fixture. In addition, the guard object can be freely changed according to the user's wishes.

  At least a part of the security means shifts to a state in which a security function is exerted or is maintained in a state in which a security mechanism is exhibited when power supply to the control means is reduced or cut off. It is desirable. If it is such, even if the said control means is destroyed or a power failure occurs, a required security function is maintained.

  As shown in FIG. 2, information on whether the user is present or away and / or information on the status or state of use of at least one of the furniture, the article, the information processing device, or electronic data If the presence information discriminating means 107 for generating presence information including the information is further provided, the presence / absence of the user, the use status of the fixture, article, information processing apparatus, or electronic data by the user is recorded. Can do.

  More specifically, the presence information determination unit 107 determines the presence information according to whether or not the user identification information receiving unit 103 has received user identification information related to the user.

  The presence information determination unit 107 determines the presence information according to whether the presence of the user is detected through a human sensor.

  Further, as shown in FIG. 3, the guard system 1 detects the use state or state of the furniture, the article, the information processing apparatus, or electronic data, and the state detection unit 109 detects the state and the state. Situation information transmitting means 110 for transmitting the situation information regarding the use status or state of the furniture, the article or the information processing apparatus or electronic data, and the situation information receiving means 112 for receiving the situation information transmitted from the situation information transmitting means In the presence information determination means 107, the presence information can be determined based on the situation information received by the situation information reception means.

  The presence information discriminating means 107 is provided when an access is made to the fixture, the article, the information processing apparatus, or electronic data that is not permitted to be accessed because the security function by the security means is activated. Then, presence information including fraudulent operation log information relating to the fact that the article, the information processing apparatus, or the electronic data has been accessed is generated. If this is the case, unauthorized access to furniture, articles, information processing devices, or electronic data can be recorded.

  In addition, the presence information discriminating means 107, when the user identification information receiving means cannot receive the user identification information related to the owner user and the user identification information receiving means receives the user identification information related to the guest user, When access is made to the fixture, the article, the information processing apparatus, or the electronic data that is unlocked by the security means and allowed to be accessed by the guest user, the fixture, the article, or the information processing apparatus Alternatively, presence information including guest operation log information related to the fact that the electronic data has been accessed is generated. If it is such, it will be possible to notify the user and other third parties of the fact that unauthorized access has been made to furniture, articles, information processing devices or electronic data. Supplementing the owner user and the guest user, the guest user usually has a narrow target range of fixtures, articles, information processing apparatuses, or electronic data that are allowed to be accessed. That is, the range in which the security function can be canceled is narrow. For example, when a predetermined work space in an office is assigned to a user and fixtures are arranged there, the user who performs the work in this workspace is the owner user, and one of the fixtures and the like arranged in the workspace is used. It can be considered that a person other than the owner user who should accept the operation on the department (an owner user's colleague, subordinate, secretary, etc.) is the guest user.

  As long as it further includes presence information storage means 109 for storing presence information generated by the presence information determination means 107, which user is present in the current workspace, which fixture, article, or Information such as whether an information processing device or electronic data is used can be notified to other users, and presence information can be utilized afterwards. Information output is a concept that encompasses transmission via a telecommunication line, writing to a required recording device, printout, display on a display screen, and the like.

  In order to further improve the convenience of the guard system 1 according to the present invention, it is desirable that the user identification information transmitting means 102 and the user identification information receiving means 103 communicate with each other wirelessly.

  When a given workspace in an office is assigned to an owner user, the owner user is mainly present and working in that workspace, but the workspace will be assigned elsewhere. Guest users also sometimes pass near the owner user's workspace. When the user identification information transmitting unit 102 and the user identification information receiving unit 103 communicate with each other wirelessly, even if the guest user just happens to pass through the vicinity of the owner user's workspace, User identification information may be transmitted and received. If the owner user is absent at this time, there is a possibility that the security functions for some fixtures and the like are unnecessarily canceled corresponding to the user identification information related to the guest user. In order to avoid such an inconvenience, the user identification information related to the owner user is defined as the distance at which the user identification information related to the guest user can be passed between the user identification information transmitting means 102 and the user identification information receiving means 103. It is preferable to set the distance shorter than the distance that can be delivered. It should be noted that the distance that can be transferred is not limited to a distance that can be transmitted and received without error in an electromagnetic sense. For example, a rough separation distance between the user identification information transmission unit 102 and the user identification information reception unit 103 is calculated by referring to the radio wave reception intensity in the user identification information reception unit 103, and the user identification is performed according to the amount of the separation distance. It is conceivable to determine whether information is considered received or not received.

  Request signal transmitting means 114 for transmitting a request signal for causing the user identification information transmitting means 102 to transmit user identification information; and a request signal receiving means 115 for receiving a request signal transmitted from the request signal transmitting means 114. In addition, when the request signal transmitting unit 114 transmits the request signal, the request signal receiving unit 115 receives the request signal, and the user identification information transmitting unit 102 receives the request signal. If the identification information is transmitted, the user identification information transmitting means 102 transmits the user identification information only in the area where the request signal transmitting means 114 exists. That is, since the user identification information transmitting unit 102 is released from the necessity of constantly transmitting the user identification information, the amount of power consumed by the transmission of the user identification information can be suppressed.

  In addition, as shown in FIG. 4, an approach detection unit 113 that detects that some person has approached the furniture, the article, or the information processing device, and an approach detection unit 113 detects the approach of some person. A request signal transmitting means 114 for transmitting a request signal for causing the user identification information transmitting means 102 to transmit user identification information, and a request signal receiving means for receiving a request signal transmitted from the request signal transmitting means 114. 115, and when the request signal transmitting unit 114 transmits the request signal, the request signal receiving unit 115 receives the request signal, and the user identification information transmitting unit based on the reception of the request signal. If 102 transmits user identification information, the request signal transmitting means 114 transmits a request signal only when the presence of some person is detected. And thus to. Therefore, the frequency of transmitting the request signal can be reduced, and the amount of radio waves propagating in the workspace can be reduced.

  An article identification information transmitting means 116 for transmitting article identification information for identifying the article attached to the article to be supervised, and an article identification information reception for receiving the article identification information transmitted from the article identification information transmitting means 116 Means 117, article identification information storage means 120 storing article identification information related to the article, and article identification information receiving means 117 receiving article identification information not stored in article identification information storage means 120. In this case, the apparatus further includes bring-in log information output means 121 for generating and outputting bring-in log information regarding the fact that the article identified by the article identification information is brought in, and investigates the presence or absence of the brought-in article. If you get it, you can easily detect items that a user borrowed from another user and brought into their workspace. Leads to to return the goods, it is possible to avoid the loss of the article.

  In addition, as shown in FIG. 5, an article identification information transmitting means 116 for transmitting article identification information for identifying an article attached to an article to be guarded, and an article transmitted from the article identification information transmitting means 116 An article identification information receiving means 117 for receiving identification information, a call signal sending means 118 for sending a call signal for causing the article identification information sending means 116 to send article identification information, and a call signal sending means 118. Call signal receiving means 119 for receiving a call signal, article identification information storage means 120 storing article identification information related to the article, and article identification information not stored in the article identification information storage means 120 Bring-in log relating to the fact that the item identified by the item identification information is brought in when the item identification information receiving means 117 receives A log information output means 121 for generating and outputting a report, and the call signal transmission means 118 can investigate the presence or absence of an article brought in by transmitting a call signal; It is possible to detect an article brought into the workspace by sending a calling signal at a required timing.

  According to the present invention, it is possible to realize a workspace supervision system that achieves both convenience and security strength.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 7, the guard system 1 of the present embodiment guards the furniture 2, the article, the information processing device 7, or the electronic data arranged in the work space allocated for each user, and is illegal when the owner user is absent. Is prevented from being accessed.

  In the workspace, furniture 2 such as a desk, a cabinet, and a wagon is arranged. The owner user who occupies the assigned work space performs work while using these fixtures 2. Then, the owner user can store his / her belongings in a storage space included in a desk drawer, cabinet, or wagon. An electric lock 2a that receives an electric signal and drives a dead bolt is mounted on the drawer, cabinet, or wagon of the desk, and can be locked when the owner user is absent. The electric lock 2a is preferably a so-called energization unlocked electric lock 2a that is unlocked by inputting an electric signal and locked by cutting off the electric signal. The electric lock 2 a prevents the above-described fixture 2 from being opened and closed illegally, and serves as security means 101 for the fixture 2.

  It is also conceivable to incorporate the locking device 3, which has developed an electric lock, into the fixture 2. For example, as shown in FIG. 8, the locking device 3 includes an electric lock 3 a that locks the fixture 2, a sensor 3 b that senses an operation on the fixture 2, and a light emission that operates when the sensor 3 b senses an operation by some person. The device 3d and the audio output device 3e, the reception circuit 3f that wirelessly receives the control release signal or control signal that is provided from the outside, the memory 3g that stores the identification information for identifying the locking device 3 and the like, and the memory 3g A transmitting circuit 3h for wirelessly transmitting the identification information, a control circuit (which may be a processor for decoding and executing a program) 3c for controlling these, and a battery for supplying power (however, the type is not limited) ) 3i. However, it does not prevent the power supply from the external power supply outlet instead of the battery 3i. The sensor 3b is a vibration sensor that detects vibration caused by an unauthorized operation on the furniture 2, an inclination sensor that detects inclination, or the like.

  When the locking device 3 receives a control release signal indicating that it should be unlocked via the receiving circuit 3f, the locking device 3 inputs an electric signal to the electric lock 3a and unlocks it. On the other hand, when a control signal indicating that locking is to be received is received, the electric signal is cut off and the electric lock 3a is locked. However, the electric lock 3a may be locked on condition that the control release signal cannot be received. Further, when an operation on the furniture 2 is sensed via the sensor 3b while the electric lock 3a is locked, a predetermined notification operation is executed. In the notification operation, the light emitting device 3d emits light or the sound output device 3e outputs sound to intimidate (or notify surrounding people) who operated the furniture 2, and / or the transmission circuit 3h. The fact that the fixture 2 has been operated is reported to the outside by transmitting identification information for identifying the locking device 3 via. However, in the state where the electric lock 3a is unlocked, even if an operation on the furniture 2 is detected, the alarming operation is not executed. This locking device 3 serves as security means 101 for the fixture 2.

  Incidentally, an open / close detection sensor (not shown) for detecting that the fixture 2 has been opened may be mounted on the locking device 3. By mounting the open / close detection sensor, it is possible to prevent troubles that occur in the locking operation by the electric lock 3a. That is, the control circuit 3c can determine whether or not to lock the electric lock 3a after investigating whether the fixture 2 is open or closed. In addition, when the fixture 2 is opened, information indicating that can be transmitted to the outside via the transmission circuit 3h.

  It is also preferable to expose the battery box to the outside of the fixture 2 in case the battery 3i is exhausted. By exposing the battery box to the outside, the battery 3i can be replaced or a spare battery can be mounted. Since the electric lock 3a that forms the basis of the security function is an unlocked type when energized, the locked state of the furniture 2 is maintained even if the battery 3i is stolen. In addition, if the electric lock 3a can be unlocked by using a physical key, the fixture 2 can be opened using the physical key even when the battery 3i is depleted.

  Rather than mechanically locking the fixture 2, it is possible to suppress unauthorized operations on the fixture 2 by using the following storage device guard device 4. The storage tool supervising device 4 is placed in a storage tool whose opening / closing operation should be restricted. Incidentally, the storage tool mentioned here is not limited to the furniture 2 such as a desk, cabinet, wagon, and includes a bag possessed by the owner user. For example, as shown in FIG. 9, the storage device guard device 4 includes a sensor 4 a that detects an operation on a storage device to be guarded, a light emitting device 4 c that operates when the sensor 4 a detects an operation by some person, and a sound. An output device 4d, a receiving circuit 4e for wirelessly receiving a control release signal provided from the outside, a memory 4f for storing information to be compared with the control release signal, identification information for identifying the storage device guard device 4, and the like, a memory It includes a transmission circuit 4g that wirelessly transmits identification information stored in 4f, a control circuit 4b that controls these, and a battery 4h that supplies power. The sensor 4a is an optical sensor that detects a light wave incident from outside the storage tool. That is, an operation on the storage device is detected by detecting a light wave incident on the storage device when the storage device is opened by some hands. However, instead of the optical sensor, a vibration sensor that detects vibration, an inclination sensor that detects inclination, or the like may be employed.

  The storage device guarding device 4 executes a predetermined reporting operation when an operation on the storage device is sensed via the sensor 4a. In the reporting operation, the light emitting device 4c emits light or the sound output device 4d outputs sound, threatens the person who operates the storage tool, and / or identifies the guard device through the transmission circuit 4g. The fact that the fixture 2 is operated is notified to the outside by transmitting the identification information. However, when a control release signal indicating that the security function is to be released is received, the above-described notification operation is not executed. The storage device guard device 4 serves as a security means 101 for the furniture 2 and other storage devices.

  In addition, if an apparatus having a function equivalent to that of the storage device guard apparatus 4 is attached to an article, the article can be guarded (that is, an unauthorized operation on the article can be suppressed).

  Moreover, you may mount the wire lock apparatus 5 in either of the fixtures 2 arrange | positioned in a work space. The wire lock device 5 is a device similar to the electric lock 2a including a main body that supports a dead bolt so that the dead bolt can be moved forward and backward, and a drive circuit that drives the dead bolt (including a solenoid). The bolt is formed in a closed ring structure, and when unlocked, the main body and the dead bolt are separated from each other to open the ring structure. The wire lock device 5 is also preferably one that is unlocked by energization. Articles attached with straps, rings and the like can be moored to the wire lock device 5 (annular structure formed by). The wire lock device 5 prevents an article moored via a strap or a ring from being illegally taken away, and serves as a security means 101 for the article.

  Apart from this, an article identification tag 6 is attached to a relatively small article such as a document used by the owner user. The outer shape of the article identification tag 6 is not limited. The tag may have a shape (eg, card, folder, file, etc.) larger than a tag generally associated with the word “tag”, or a shape smaller than the tag (eg, clip, ring, staple, tip, etc.). It may be what makes. For example, as shown in FIG. 10, the article identification tag 6 is stored in a memory 6 b for storing article identification information for identifying the article identification tag 6 (or an article to which the article identification tag 6 is attached) and the like, and the memory 6 b. A transmitter circuit 6c for wirelessly transmitting the article identification information being received, a receiver circuit 6d for wirelessly receiving a paging signal brought from the outside, a control circuit 6a for controlling these, and a battery 6e for supplying power, At least the article identification information sending means 116 that sends the article identification information. Basically, the article identification tag 6 continues to send article identification information intermittently. However, the article identification information is also returned when a call signal is received from the outside. That is, the article identification tag 6 also functions as the call signal receiving unit 119. As will be described later, the article identification tag 6 is a constituent element of the security means 101 that implements a security function for restricting access to the article to which the article identification tag 6 is attached.

  Incidentally, an optical sensor (not shown) for detecting light may be mounted on the article identification tag 6 and the article identification information may be transmitted only when the light is detected. By mounting the optical sensor, when an article attached to the article identification tag 6 is stored in the fixture 2 or the like (after transmitting a signal to the effect of suppressing the alarm operation to the control device 5) ) Transmission of article identification information can be stopped. Furthermore, when the user identification information transmitted from the following user identification tag 8 is received via the receiving circuit 6d, the transmission of the article identification information may be stopped. With such a configuration, it is possible to suppress consumption of the battery 6e.

  As shown in FIG. 11, for example, the information processing apparatus 7 used by a user who performs work includes a processor 7a, a main memory 7b, an auxiliary storage device 7c, a display 7d, a display control device 7e, an operation operation input device 7f, a communication It has hardware resources such as an interface 7g and can execute various information processing for handling electronic data, such as an existing personal computer or PDA (Personal Digital Assistants). The display control device 7e generates a video chip 7e1 (or graphics chip), image data, etc. having a function of generating image data to be displayed based on the drawing instruction received from the processor 7a and sending it to the display 7d. A known device such as a video memory 7e2 (Video RAM) that plays a role of storing temporarily is used. The operation input device 7f is a pointing device such as a keyboard, a mouse, or a track pad that receives an operation input by a user's hand. The communication interface 7g is an interface for performing data communication such as a NIC (Network Interface Card), a wireless LAN (Local Area Network) transceiver, and a USB (Universal Serial Bus). Usually, an operating system program, a device driver program, various application programs, and the like are installed in the auxiliary storage device 7c in advance, and are read from the auxiliary storage device 7c into the main memory 7b and decoded by the processor 7a. . Then, according to the program, the above hardware resources are operated. This information processing apparatus 7 has a screen saver function (hidden information displayed on the screen of the display 7d and reserves acceptance of operations) and a user authentication function (login prompt is displayed on the display 7d) by an installed program. Display on the screen, and accept input of account information to determine whether or not the user can log in). Account information is information such as a user ID and / or password used for user authentication, and the range of accessible electronic data and available application programs may differ for each account information. These user authentication module programs or screen saver module programs prevent unauthorized operation of the information processing apparatus 7 or electronic data, and serve as security means 101 for the information processing apparatus 7 or electronic data. However, the functions other than the screen saver module (locking the operation input device 7f, encryption of electronic data, etc.) are not prevented from protecting the information processing apparatus 7 and the electronic data. The information processing apparatus 7 is connected to an information processing apparatus 7 disposed in another user's workspace, a server computer (not shown), or the like via an electric communication line such as a LAN or a WAN (Wide Area Network). Yes.

  Each user has a user identification tag 8. The user identification tag 8 is a key for releasing the security function for the furniture 2, the article, the information processing apparatus 7, or the electronic data. Incidentally, the outer shape is not limited. The tag may have a shape larger than a tag generally associated with the word “tag”, or may have a shape smaller than a tag. For example, as shown in FIG. 12, the user identification tag 8 includes a memory 8b for storing user identification information for identifying a user, a transmission circuit 8c for wirelessly transmitting the user identification information stored in the memory 8b, and an external It comprises a receiving circuit 8d for wirelessly receiving a request signal resulting from it, a control circuit 8a for controlling these, and a battery 8e for supplying power, and functions as user identification information transmitting means 102 for transmitting at least user identification information. In addition, in order to suppress consumption of the battery 8e, the user identification tag 8 in this embodiment shall return user identification information, when a request signal is received. That is, the user identification tag 8 also functions as the request signal receiving unit 115. However, the user identification information may simply be continuously transmitted regardless of the presence or absence of the request signal.

  A control device 9 is interposed between the furniture 2, the article or the information processing device 7 arranged in the workspace and the user identification tag 8 possessed by the user. For example, as shown in FIG. 13, the control device 9 includes a memory 9b for storing various information, a light emitting device 9c and a sound output device 9d for notifying the user of the situation, and an operation input for receiving an operation input by the user. Device 9e, electric signal interface 9f for inputting electric signals to electric lock 2a and wire lock device 5, transmission circuit 9g for wireless transmission of signals, reception circuit 9h for wireless reception of signals, data communication A communication interface 9i for performing the control, a control circuit 9a for controlling these, a power supply circuit 9j for supplying electric power obtained from the outside to the control device 9 itself, other electric devices (not shown), the other electric devices, etc. And one or a plurality of power supply outlets 9l for connecting the power cords. The operation input device 9e is, for example, an operation button that is pressed with the user's finger. The electrical signal interface 9f and the communication interface 9i may be wireless or wired. Furthermore, the control device 9 is also connected to a human sensor 9k that senses that there are several people in the vicinity of the furniture 2, the article, or the information processing device 7 arranged in the workspace. The aspect of the human sensor 9k is not particularly limited. The human sensor 9k may be a passive infrared sensor or a distance measuring sensor.

  The control device 9 is connected to the electric lock 2a and the wire lock device 5 mounted on the fixture 2 via an electric signal interface 9f, and is connected to the information processing device 7 via a communication interface 9i. In addition, the locking device 3, the storage device guard device 4, the article identification tag 6, and the user identification tag 8 communicate wirelessly using the functions of the transmission circuit 9g and the reception circuit 9h. In addition, it is possible to supply power to other electrical devices connected via the power supply outlet 9l, and to control power supply / cutoff to the electrical devices and the like.

  In the memory 9 b of the control device 9, authority information that prescribes the furniture 2, the article, the information processing device 7, or electronic data that is allowed to be accessed for each user is stored in advance. The authority information includes, for example, information for identifying the fixture 2 accessible by the user (including identification information for identifying the locking device 3 and identification information for identifying the storage device guard device 4), article identification information for identifying the article, Account information and the like for logging in to the information processing apparatus 7 are described. In addition, information about whether each power outlet is set to a power supply state or a cutoff state when the user is present may be described. The authority information for each user is stored in the memory 9b in association with user identification information for identifying the user. Usually, the owner user is allowed to access all the fixtures 2 etc. arranged in the workspace occupied by the owner user, and the authority information related to the owner user describes information for identifying all the fixtures 2 etc. . On the other hand, the guest user is only allowed to access a part of the fixtures 2 etc. arranged in the same workspace, and the authority information related to the guest user includes only information for identifying some fixtures 2 etc. Is described.

  Here, the relationship between each security means 101 and the control device 9 will be supplemented. First, when the security function by the electric lock 2a and the wire lock device 5 mounted on the fixture 2 is activated (locked state), the control device 9 is input to the target electric lock 2a or the wire lock device 5. Block electrical signals. As a result, the electric lock 2a and the wire lock device 5 are locked. On the contrary, when the security function by the electric lock 2a and the wire lock device 5 is released (unlocked state), the input of electric signals from the control device 9 to the electric lock 2a and the wire lock device 5 is resumed. . It can be said that the electric signal input to the electric lock 2a and the wire lock device 5 is one of control release signals for releasing the security function.

  When the security function by the locking device 3 is activated (when the electric lock 3a is locked and a notification operation is performed when an operation on the fixture 2 is sensed), the control device 9 is the target locking device. A control signal indicating that it should be locked is sent wirelessly. Usually, the control signal includes identification information for identifying the control device 9 as a transmission source and identification information for identifying the locking device 3 as a destination. On the other hand, in the memory of the locking device 3, identification information for identifying the control device 9 serving as a transmission source and identification information for identifying itself are stored in advance. The locking device 3 that wirelessly received the control signal via the receiving circuit 3f compares the identification information included in the control signal with the identification information stored in the memory 3g, and if the two match, the control signal is Judge that it was sent to you. Upon receiving the control signal, the locking device 3 locks the fixture 2 by cutting off the electric signal input to the electric lock 3a. However, instead of locking the fixture 2 by transmitting a control signal from the control device 9 to the locking device 3, the fixture is stopped by stopping transmission of the control release signal from the control device 9 to the locking device 3. It is also possible to perform the locking of 2. In this state, when an operation on the furniture 2 is sensed, the locking device 3 activates the light emitting device 3d and the sound output device 3e to perform light emission and sound output notification. At the same time, identification information for identifying itself stored in the memory 3g is transmitted by radio. The control device 9 receives the identification information for identifying the locking device 3, thereby obtaining the fact that the operation on the fixture 2 in which the locking device 3 is incorporated has been performed. Incidentally, if the fixture 2 remains open before locking, the electric lock 3a cannot lock the fixture 2. Even when locking fails, the locking device 3 wirelessly transmits information indicating that fact (usually including identification information for identifying the locking device 3). Receiving this, the control device 9 knows that the locking of the fixture 2 in which the locking device 3 is incorporated has failed. On the other hand, when the security function by the locking device 3 is released (when the electric lock 3a is unlocked and no alarm operation is performed even if an operation on the fixture 2 is detected), the control device 9 A control release signal indicating that the unlocking should be performed is sent to the locking device 3. The control release signal also includes identification information for identifying the control device 9 and identification information for identifying the locking device 3. The locking device 3 that wirelessly received the control release signal via the receiving circuit 3f compares the identification information included in the control release signal with the identification information stored in the memory 3g, and if the two match, control is performed. It is determined that the release signal is sent to itself. Receiving the control release signal, the locking device 3 inputs the electric signal to the electric lock 3a to unlock the fixture 2. In this state, even if an operation on the furniture 2 is sensed, no light emission or sound output is issued. It should be noted that the locking device 3 in the present embodiment controls the operation of the fixture 2 with the sensor 3a regardless of whether the security function is activated or released, in other words, whether the security function is locked or unlocked. When this is detected, identification information for identifying the locking device 3 is transmitted by radio. Then, the control device 9 also receives the identification information transmitted from the locking device 3 regardless of whether the security function is activated or deactivated, and learns the fact that the operation on the furniture 2 has been performed. The control device 9 regards an operation performed in a state where the security function for the locking device 3 is activated as an unauthorized operation, and performs an operation performed in a state where the security function is released as a regular operation. Consider it.

  When the security function by the storage device guarding device 4 is activated (a state in which a reporting operation is performed when an operation on the furniture 2 is detected), the control device 9 is directed toward the target storage device guarding device 4. Activation of the security function is realized by not sending a control release signal for canceling the security function. There is no opportunity to transmit a control signal to activate the security function to the storage device guard apparatus 4. On the other hand, when the security function by the storage device guard device 4 is released (when the operation for the furniture 2 is sensed, the alarm operation is not performed), the target device is directed to the storage device guard device 4. Control release signal to release the security function. The control device 9 transmits a control release signal to the locking device 3 by push-type communication, but transmits a control release signal to the storage device guard device 4 by pull-type communication. That is, the storage device guard device 4 wirelessly transmits identification information for identifying the locking device 3 when an operation on the furniture 2 is sensed via the sensor 4a. The control device 9 knows the fact that the operation has been performed on the furniture 2 by receiving the identification information provided from the storage device guard device 4, but at the same time returns a control release signal to the storage device guard device 4. Determine whether or not. That is, the control device 9 regards an operation performed while the security function by the storage device guard device 4 is activated as an unauthorized operation, and properly performs an operation performed while the security function is released. Is considered to be an operation. If the security function is activated, the control release signal is not returned, and if the security function is released, the control release signal is returned. Usually, the control release signal includes identification information for identifying the control device 9 as a transmission source and identification information for identifying the storage device guard device 4 as a destination. Also in the memory 4f of the storage device guarding device 4, identification information for identifying the control device 9 serving as a transmission source and identification information for identifying itself are stored in advance. The locking device 3 that wirelessly received the control release signal compares the identification information included in the control signal with the identification information stored in the memory 4f, and if the two match, the control release signal is directed to itself. Judge that it was sent. The storage device guard device 4 does not emit light and outputs sound when it receives a control release signal addressed to itself, but performs light emission and sound output when it cannot receive it.

  The security function for the article with the article identification tag 6 is different from that of the electric lock 2a, the locking device 3, the storage device guard device 4, and the like. This is because the article identification tag 6 itself cannot perform locking, reporting, or the like. The security function for the article is implemented by the cooperation of the article identification tag 6 and the control device 9. More specifically, the article identification tag 6 intermittently transmits article identification information for identifying an article wirelessly, and the control device 9 wirelessly receives the article identification information via the receiving circuit 9h. In the memory 9b of the control device 9, article identification information relating to an article to be guarded is stored in advance. At this time, the control device 9 functions as the article identification information storage means 120. The control device 9 periodically checks whether or not the same item identification information as the item identification information stored in the memory 9b can be received. If any item identification information cannot be received while the security function for the item is activated, the item identified by the item identification information that cannot be received is considered to have been illegally taken out, and Execute the information operation. In the reporting operation, the light emitting device 9c and the sound output device 9d mounted on the control device 9 are operated to emit light and output sound, and notify the owner user, guest user, etc. of the fact that the article was illegally taken out. . On the contrary, in the state in which the security function for the article is released, even if any of the article identification information stored in the memory 9b cannot be received, it is considered that the article has not been illegally taken out, and the alerting operation is performed. Do not do.

  When the security function in the information processing device 7 is activated (the screen of the display 7d is hidden and the login prompt is displayed to prompt the user to input account information), the control device 9 is directed to the information processing device 7. A control signal for starting the screen saver module and the user authentication module is transmitted. The information processing apparatus 7 that has received the control signal conceals the screen of the display 7d according to the program and reserves the acceptance of the operation. Conversely, when a control release signal indicating that the security function should be released is sent from the control device 9 to the information processing device 7, the security function in the information processing device 7 is released (the login prompt is erased and the screen of the display 7d is displayed). It is possible to cancel the concealment and resume the operation reception). Incidentally, the control release signal may include account information necessary for releasing the security function. The information processing apparatus 7 that has received the control release signal releases the security function described above and resumes accepting the operation according to the program. As a result, the information processing apparatus 7 can be used again.

  The control device 9 plays a role as the security means 101 for an electrical device or the like having a power cord connected to the power supply outlet 9l. In other words, the control device 9 can perform security control on the electrical device or the like by turning on / off the power supply to the electrical device or the like. When the security function for the electrical device or the like is activated (the electrical device or the like is disabled), the control device 9 controls the power supply circuit 9j to cut off the power supply via the power supply outlet 9l. On the other hand, when the security function for the electric device or the like is released (the electric device or the like can be used), the power supply circuit 9j is controlled to restart the power supply via the power supply outlet 9l.

  Generally speaking, the control device 9 functions as a control unit 104 that activates the security function by the security unit 101 and a control release unit 105 that releases the security function.

  Hereinafter, the procedure of the overall operation of the guard system 1 will be described. When there is no user having a legitimate authority in the workspace, the guard system 1 is in the security mode. In the security mode, the control device 9 activates all the security functions for the furniture 2, the article and the information processing device 7, or the electronic data.

  When several people appear in the workspace, it is determined whether or not this person is a user having a legitimate authority. For this purpose, the control device 9 tries to receive user identification information transmitted from the user identification tag 8 possessed by this person. The control device 9 simply waits for the reception of the user identification information, or when the person sensor 9k senses that some person has approached the furniture 2, the article or the information processing device 7, the user identification information A request signal for presentation is transmitted by radio. At this time, the control device 9 functions as the approach detection means 113 and the request signal transmission means 114. However, the control device 9 may transmit a request signal when an operation input by the user is received via the operation input device 9e. The user identification tag 8 that has received the request signal transmitted by the control device 9 returns user identification information. That is, the user identification tag 8 transmits the user identification information only in the workspace where the request signal can be received, in other words, in the workspace where the control device 9 is arranged, and transmits the user identification information outside the workspace. There is nothing. This leads to suppression of consumption of the battery 8e in the user identification tag 8. In addition, the control device 9 applies the user identification tag 8 only when the human sensor 9k senses the presence of the user, in other words, only when the user is sufficiently close to the furniture 2, the article, or the information processing device 7. A request signal for Therefore, the frequency of transmitting the request signal can be reduced, and the amount of radio waves propagating in the workspace can be reduced. The control device 9 receives user identification information returned from the user identification tag 8. At this time, the control device 9 functions as the user identification information receiving means 103.

  Thereafter, the control device 9 checks whether or not the user identification information corresponding to the received user identification information is stored in the memory, and determines whether or not this person is a user having a legitimate authority. . If the user identification information corresponding to the received user identification information is stored in the memory 9b, it is determined that a user having a valid authority has appeared in the workspace. And it transfers to the mode corresponding to the user identification information which concerns on the user. That is, referring to the authority information stored in the memory 9b in association with the user identification information, the security function for the furniture 2, the article, the information processing apparatus 7, or the electronic data that is allowed to be accessed by the user is canceled. . For example, if the user identification information related to the owner user is received, the mode shifts to the owner mode for canceling the security function for all the fixtures 2 etc. arranged in the workspace, and the user identification information related to the guest user is received. If it does, it will transfer to the guest mode which cancels | releases the security function about some fixtures 2 grade | etc., Prescribed | regulated by authority information. Incidentally, when both the user identification information related to the owner user and the user identification information related to the guest user are received, the user identification information related to the owner user is prioritized and the mode is shifted to the owner mode.

  Note that when the user identification information is transferred between the user identification tag 8 and the control device 9, a distance that allows the user identification information related to the owner user to be effectively transferred is set relatively long, and the user identification information related to the guest user is It is desirable to set a distance that can be effectively delivered relatively short. That is, the guest user cannot pass the user identification information between the user identification tag 8 owned by the guest user and the control device 9 unless he / she is closer to the control device 9 than the owner user, and the guest mode is changed. I can't call it.

  If the user identification information corresponding to the received user identification information is not stored in the memory 9b, or if the user identification information cannot be received, the person who appears in the workspace is not a user with a legitimate authority. The security mode is maintained.

  When a user having a legitimate authority exists in the workspace, the guard system 1 is in the owner mode or the guest mode. In the owner mode or the guest mode, at least a part of the security function for the furniture 2, the article, the information processing apparatus 7, or the electronic data is canceled. If a user with a legitimate authority leaves the workspace, it immediately shifts to the security mode and activates the released security mode. That is, when the user identification information relating to the legitimate user cannot be received, the control device 9 activates all the security functions for the furniture 2, the article and the information processing device 7, or the electronic data, and shifts to the security mode. More specifically, the user identification information transmitted from the user identification tag 8 cannot be received when the presence of the user in the vicinity of the furniture 2, the article or the information processing device 7 can no longer be sensed via the human sensor 9 k. Sometimes, it shifts to a security mode that activates all security functions. Note that when the control device 9 senses a moving object via the human sensor 9k, the control device 9 transmits a request signal and tries to receive the user identification information again. In this manner, if the sensing by the human sensor 9k is used as a kick to cause transmission / reception of user identification information, battery consumption in the user identification tag 8 can be reduced.

The security mode is activated in a situation where the owner user who occupies the work space and is working is away. It does not matter whether the owner user's absence is short-term or long-term (for example, returning home, business trip, holiday, etc.). However, if the owner user does not appear in the workspace for a long period of time, it is preferable to shift to a mode that saves power as much as possible. The guard system 1 of the present embodiment can shift to a sleep mode that focuses on power saving in addition to the security mode, the owner mode, and the guest mode. A user who wants to activate the sleep mode performs an operation input indicating that the mode should be shifted to the sleep mode via the operation input device 9e mounted on the control device 9. The control device 9 that has received this operation input shifts to the sleep mode. The control device 9 at this time functions as the sleep operation accepting means 106 shown in FIG. Enumerating the features of sleep mode,
Regardless of whether or not the presence of some person is detected via the human sensor 9k, the control device 9 does not transmit a request signal. Accordingly, user identification information is not transmitted from the user identification tag 8 that has entered the workspace to the control device 9.
-With respect to the electric lock 2a and the wire lock device 5, the input of an electric signal as a control release signal is kept blocked. As already described, since the electric lock 2a and the wire lock device 5 are unlocked when energized, these locks are maintained without power supply.
A control signal is transmitted to the locking device 3 indicating that it should be locked when shifting to the sleep mode. However, as already described, it is possible to adopt a mode in which locking by the locking device 3 is triggered by stopping transmission of the control release signal. Since the electric lock 3a in the locking device 3 is also unlocked when energized, the locking is maintained without power supply.
-The control release signal to the effect that the security function should be released is not sent to the storage device guard device 4. The storage device guard device 4 is maintained in a state where the security function is activated.
A signal for sleep or shutdown of the system is transmitted to the information processing device 7 when the mode is shifted to the sleep mode. The information processing apparatus 7 that has received this signal performs sleep or shutdown according to the program.

  As described above, the control device 9 in the sleep mode can reduce or cut off the power supply to the electric signal interface, the transmission circuit, the reception circuit, and the like, and can realize power saving.

  Incidentally, if an operation input device (not shown) is mounted on the user identification tag 8, the user performs an operation input for instructing transition to the sleep mode using the operation input device on the user identification tag 8. It is also conceivable that the user identification tag 8 that has received the operation input wirelessly transmits a signal indicating that it should shift to the sleep mode to the control device 9. Further, in addition to the case where the user has received an explicit instruction to shift to the sleep mode, the predetermined time has passed on the condition that the presence of the user can no longer be detected via the motion sensor 9k. It is good also as what transfers to sleep mode on condition.

  On the contrary, when returning from the sleep mode to a mode other than the sleep mode, an operation input indicating that the user should exit from the sleep mode is performed via the operation input device 9e mounted on the control device 9. The control device 9 that has received this operation input shifts from the sleep mode to the security mode. At this time, the control device 9 transmits a signal for starting the system to the information processing device 7. The information processing apparatus 7 that has received this signal activates the operating system according to the program. When the mode is changed from the sleep mode to the security mode, the communication between the user identification tag 8 possessed by the user and the control device 9 is restored, so the mode is changed to the owner mode or guest mode corresponding to the user identification information related to the user. Will be performed.

  In the transition from the sleep mode to another mode, the user uses the operation input device on the user identification tag 8 to input an instruction indicating that the user should get out of the sleep mode, and receives the operation input. Can be transmitted wirelessly to the control device 9 indicating that the device should exit from the sleep mode. Further, the mode may be shifted from the sleep mode to another mode on condition that the presence of the user can be sensed through the human sensor 9k.

  In the supervision system 1 of the present embodiment, information on whether a user is present or away from the workspace, the fixture 2, the article, the information processing device 7 or the electronic data used in the workspace Presence information such as information about the status is generated. When a transition is made from one mode to another, a log relating to the transition of the mode is generated. In particular, the transition between owner mode and non-owner mode is directly linked to whether the owner user is present or absent from the workspace, so the logs related to mode transitions are shared with other users. It will be very useful. When the mode is changed from one mode to another mode, the control device 9 generates a log relating to the mode change. This log includes, for example, information on the date and time when the mode transition occurred, information about which mode transitioned to (in particular, the user identification of the user who caused the mode transition when transitioning to the owner mode or guest mode) Information), and information related to the security function that is canceled by shifting to the mode. Incidentally, information on the security function to be released can be obtained by referring to the authority information stored in the memory 9b. Logs relating to the subsequent modes generated are temporarily held in the memory 9b of the control device 9. The log regarding the mode transition is a part of the presence information. At this time, the control device 9 functions as presence information determination means 107 for generating presence information and presence information storage means 109 for storing presence information.

  A log regarding the mode transition generated by the control device 9 is output each time the control device 9 generates the log. In the present embodiment, the control device 9 outputs the presence information in such a manner that the presence information is transmitted to the information processing device 7 connected via the communication interface. At this time, the control device 9 functions as presence information output means 108. The information processing device 7 that has received the presence information provided from the control device 9 further transmits this presence information to a server computer (not shown) according to the program. The information processing apparatus 7 arranged in the workspace of another user can acquire presence information from this server computer. Then, the other user uses the information processing device 7 to acquire and view presence information, so that which user is currently present in this workspace, is present in this workspace. It is possible to know whether it is possible for a user who uses the information processing device 7 to exchange information (such as e-mail and video conference) with the other user while staying in his / her workspace. However, it does not prevent the presence information from being output in a manner such as hard copy output using a printer (not shown) or writing to a required recording medium.

  In addition, when an opening / closing operation is performed on the fixture 2 in which the locking device 3 is incorporated or the fixture 2 in which the storage device guard device 4 is accommodated, an article with the article identification tag 6 is taken out, or information When the processing device 7 or electronic data is used, an access log relating to the fact that the furniture 2, the article, the information processing device 7 or the electronic data is accessed is generated. As described above, when the fixture 2 is operated, the locking device 3 or the storage device guard device 4 wirelessly transmits identification information for identifying itself, and the control device 9 receives the identification information to operate the fixture 2. It is possible to know the facts made. For the article attached to the article identification tag 6, when the control device 9 can no longer receive the article identification information transmitted from the article identification tag 6, the fact that the article has been taken out of the workspace is known. It is possible to obtain. As for the information processing apparatus 7, for example, when the operation input device accepts some operation input, information indicating that is transmitted from the information processing apparatus 7 to the control apparatus 9, or the information processing apparatus 7 It is possible to know the fact that the information processing apparatus 7 has been accessed by sensing the presence of a person who wants to access the information processing device 9k via the human sensor 9k. Regarding the electronic data, the information processing device 7 records a log of reading and writing to the data file in accordance with the operating system program, and the control device 9 obtains this log so that the fact of use of the electronic data can be known. is there. At this time, the locking device 4, the storage device guard device 4, and the information processing device 7 function as the situation information sensing unit 110 and the situation information transmission unit 111. In addition, the control device 9 functions as status information receiving means 112.

  The control device 9 that has obtained the fact that the access to the furniture 2 and the like has been performed generates an access log. This log includes, for example, information identifying the accessed furniture 2, article or information processing device 7 or electronic data, information regarding the date and time when access was performed, user identification information identifying the user who performed access, and the like It is. The generated access log is temporarily stored in the memory 9b of the control device 9. The access log is also part of the presence information. Also at this time, the control device 9 functions as the presence information determination unit 107 and the presence information storage unit 109.

  Incidentally, the meaning of the access log differs depending on how many people have accessed the furniture 2 or the like. As already described, the control device 9 knows how many users exist in the workspace by receiving the user identification information transmitted from the user identification tag 8. An access made in the owner mode, that is, in a situation where the owner user exists can be regarded as an access by the owner user (or accepted by the owner user), and the access log generated at this time is the owner user. This is the owner operation log information. Access made in guest mode, i.e., where there is no owner user but there is a guest user, can be considered as access by (or accepted by the guest user) The generated access log becomes guest operation log information by the guest user. Therefore, an access made under the security mode or sleep mode can be regarded as an unauthorized access made when the owner user or guest user is absent, and the access log generated at this time is an unauthorized operation log. Information.

  The access log generated by the control device 9, in other words, owner operation log information, guest operation log information, or unauthorized operation log information is output step by step. In the present embodiment, the control device 9 outputs these access logs in such a manner that the owner operation log information, guest operation log information, or unauthorized operation log information is transmitted to the information processing device 7 connected via the communication interface. I do. Also at this time, the control device 9 functions as the presence information output means 108. The information processing device 7 that has received the access log provided by the control device 9 accumulates it in a required storage area of the main memory or auxiliary storage device, and provides it to the owner user. When the generated access log is an unauthorized operation log, the control device 9 or the information processing device 7 transmits this to the owner user, a security officer, a security officer, etc. in the form of e-mail, for example. It is desirable to report the fact of unauthorized access. Information regarding the address that is the destination of transmission of the unauthorized operation log information is stored in advance in the memory 9b of the control device 9 or the auxiliary storage device of the information processing device 7. The information processing apparatus 7 further transmits owner operation log information, guest operation log information, or unauthorized operation log information to a server computer (not shown) according to the program. The information processing apparatus 7 arranged in the workspace of another user can acquire presence information from this server computer. Then, the other user acquires and browses the access log using the information processing apparatus 7 to know the fact of the legitimate / unauthorized access in this workspace while staying in his / her workspace. be able to. However, it does not prevent the guest operation log information or the illegal operation log information from being output in a manner such as hard copy output using a printer (not shown) and writing to a required recording medium.

  By the way, an article of another user may be brought into the workspace of a certain user and left as it is. This occurs when a user borrows an article and leans it up as it is or when it is accidentally placed in a user's workspace as a forgotten or lost item. In such a case, the present supervision system 1 can easily detect the presence of an article of another user. As the article and the article identification tag 6 attached thereto are transported from one workspace to another by the user's hand, the control device 9 in the source workspace first receives the article identification information. Thereafter, the control device 9 in the destination workspace receives the same article identification information. The control device 9 that has received the article identification information compares the received article identification information with the article identification information related to the article to be protected, which is stored in advance in the memory 9b. The article identification information stored in the memory 9b can be said to identify an article that should exist in the workspace assigned to the owner user, that is, an article that should be under the control of the owner user. Paradoxically speaking, the article identification information not stored in the memory 9b identifies an article that should exist in the workspace of another user, that is, an article that should be under the control of another user. Therefore, if the article identification information not stored in the memory 9b has been received, the owner user, guest user, or the like is informed that an article that is the property of another user exists in this workspace. In order to notify, a predetermined notification operation is executed. In the reporting operation, for example, the light emitting device 9c and the sound output device 9d mounted on the control device 9 are operated to perform light emission and sound output. At the same time, the control device 9 generates a carry-in log relating to the fact that other user's goods are brought in. This log includes, for example, information related to the date and time when another user's article is detected, article identification information for identifying the article, and the like. The generated log is temporarily stored in the memory 9b of the control device 9.

  Thereafter, the control device 9 outputs the brought-in log information to the information processing device 7 connected via the communication interface. At this time, the control device 9 functions as a bring-in log information output unit 121. The information processing apparatus 7 that has received the brought-in log information from the control device 9 further transmits this brought-in log information to a server computer (not shown) according to the program. The information processing apparatus 7 arranged in the work space of another user can acquire bring-in log information from this server computer.

  As an aside, the electric lock 2 a, the locking device 3 a, the storage device guard device 4, the wire lock device 5 or the information processing device 7 and the user identification tag 8 can exchange with each other without using the control device 9. That is, the user identification information transmitted from the user identification tag 8 is regarded as a control release signal for releasing the security function by the electric lock 2a, the locking device 3a, the storage device guard device 4, the wire lock device 5, or the information processing device 7. Thus, it is possible to construct a system in which the security function is released when a user having a legitimate authority is present near the storage device and the security function is activated when the user leaves the storage device. In this case, user identification information relating to a user having a legitimate authority is stored in advance in the memory of the electric lock 2a, the locking device 3a, the storage device guard device 4, the wire lock device 5, or the information processing device 7. When the electric lock 2a, the locking device 3a, the storage device guard device 4, the wire lock device 5 or the information processing device 7 wirelessly receives the user identification information, the user identification information and the user stored in the memory are stored. Compare with identification information. If they match as a result of the comparison, the electric lock 2a, the locking device 3a, the storage device guard device 4, the wire lock device 5, or the information processing device 7 releases the security function. For example, the storage device guard device 4 does not perform a predetermined reporting operation even if an operation on the storage device is detected. On the contrary, if the user identification information corresponding to the user identification information stored in the memory cannot be received, the electric lock 2a, the locking device 3a, the storage device guard device 4, the wire lock device 5 or the information processing device 7 Activate the security function. For example, the storage device guard device 4 executes a predetermined alarm operation when an operation on the storage device is detected. The storage device guard device 4 at this time functions as the user identification information receiving unit 103, the control unit 104, and the control release unit 105.

  As described above, the electric lock 2a, the locking device 3a, the storage device guard device 4, the wire lock device 5 or the information processing device 7 may communicate with the control device 9 or may communicate with the user identification tag 8. . In particular, the storage device guard device 4 is detachable with respect to the furniture 2 and other storage devices, and its installation location can be easily changed, so that it is operated in a situation where the control device 9 is absent. There is a high possibility. From here, taking the storage device guard device 4 as an example, the procedure for establishing communication with the control device 9 or the user identification tag 8 will be specifically described. When the storage device supervision apparatus 4 senses an operation on the storage device via the sensor 4a, the storage device guard device 4 wirelessly transmits information indicating the fact (hereinafter referred to as sensing information). This sensing information includes identification information for identifying the storage device guard device 4. After transmitting the sensing information, the storage device guard device 4 waits for a control release signal that will be provided by the control device 9. The storage device guard device 4 at this time functions as a control release signal receiving means. As already described, the control device 9 receives the sensing information including the identification information for identifying the storage device guard device 4, and determines whether the operation on the storage device is an unauthorized operation or a regular operation. If it is determined that the operation on the storage device is a normal operation, a control release signal for releasing the security is returned from the control device 9 toward the storage device guard device 4. When the control release signal is successfully received, the storage device guard device 4 releases the security function, that is, does not perform the alarming operation. However, if communication between the storage device guard device 4 and the control device 9 is impossible, a control release signal is not provided to the storage device guard device 4. Therefore, the storage device guard device 4 waits for a control release signal for a predetermined timeout period, and switches to standby for reception of user identification information if the control release signal cannot be received before the timeout period elapses (in particular, user identification). If the tag 3 transmits user identification information when a predetermined request signal is wirelessly received, it attempts to receive the user identification information by wirelessly transmitting the request signal). That is, the storage device guard device 4 wirelessly receives the user identification information transmitted from the user identification tag 8, and determines whether or not the storage device can be operated based on this. In the storage device guarding device 4, user identification information relating to a user who has the authority to operate the storage device is registered in advance as authority information. Specifically, user identification information relating to a user having a legitimate authority is stored in the memory 4f of the storage device guard apparatus 4.

  The container guarding device 4 that has not received the control release signal provided by the control device 9 receives the user identification information provided by the user identification tag 8 via the receiving circuit 4f. Then, the received user identification information is compared with the user identification information stored in the memory 4f to determine whether or not a user having a legitimate authority exists in the vicinity of the storage device guard apparatus 4. . When the user identification information corresponding to the user identification information stored in the memory 4f is received, it means that there is a user having a legitimate authority in the vicinity. In that case, the storage device guard device 4 cancels the security function and does not perform the alarm operation. The storage device guard device 4 at this time functions as a control release unit. On the contrary, when the user identification information corresponding to the user identification information stored in the memory 4f cannot be received, it means that there is no user having a legitimate authority in the vicinity. In that case, the storage device guard device 4 maintains the security function, and performs a reporting operation as a result of sensing an operation on the article. Here, the storage device guard device 4 has been described as an example, but the electric lock 2a, the lock device 3a, the wire lock, and the like except that the hardware resources or software resources for configuring the security means 101 are different. The same applies to the apparatus 5 or the information processing apparatus 7.

  According to this embodiment, at least one fixture 2, article or information processing device 7 or electronic data that should be restricted from being accessed by a person other than a user having a legitimate authority, At least one security means 101 which is attached to each of the article or the information processing apparatus 7 and exhibits a security function for restricting access to the furniture 2, the article or the information processing apparatus 7 or electronic data, and a legitimate authority A user identification information transmitting unit 102 for transmitting user identification information for identifying the user, and a user identification information receiving unit 103 for receiving user identification information transmitted from the user identification information transmitting unit 102. The user identification information receiving unit 103 cannot receive the user identification information related to the user. In this case, when the user identification information receiving means 103 receives the control means 104 that activates the security function by the security means 101 and the user identification information related to the user, it corresponds to the received user identification information. Since the guard system 1 comprising the fixture 2, the article, the information processing device 7, or the control release means 105 for releasing the security function for the electronic data that is allowed to be accessed is constructed, it has a legitimate authority. When a user appears in the workspace and user identification information relating to this user is transmitted and received between the user identification information transmitting means 102 and the user identification information receiving means 103, the fixture 2, articles or information arranged in the workspace Security function for processing device 7 or electronic data is released That. Then, when a user having a legitimate authority leaves the workspace and the transmission / reception of user identification information relating to the user becomes impossible, the security function for the fixture 2 and the like arranged in the workspace is activated again. In the present supervision system 1, even if there are a plurality of fixtures 2, articles, and information processing devices 7 to be guarded, a user who is a key for releasing the security functions for these fixtures 2, articles, information processing devices 7, etc. The number of identification information transmission means 102 may be one. Therefore, by distributing the user identification information transmitting means 102 to each user one by one, each user can cancel the security function for the furniture 2, the article, the information processing apparatus 7, or the electronic data as necessary. It becomes possible. In addition, the range for releasing the security function can be changed in accordance with the user identification information transmitted by the user identification information transmitting means 102. Therefore, an increase in security risk associated with distributing a plurality of keys to a plurality of users can be avoided and high convenience can be provided.

  A part or all of the security means 101 receives a predetermined control release signal and stops its security function. The control release means 105 releases control to part or all of the security means 101. A sleep operation receiving means 106 for releasing the security function by transmitting a signal and receiving an operation input indicating that power supply to the user identification information receiving means 103 or the control releasing means 105 is reduced or cut off. And when the operation input is received by the sleep operation receiving means 106, the power supply to the user identification information receiving means 103 or the control releasing means 105 is reduced or cut off, and the user identification information related to the user is Regardless of whether or not it can be received, the control release means 105 sends a control release signal. Because it is cast, power saving, the utility of preventing such a fire due to leakage can be obtained.

  Depending on whether or not the user identification information receiving means 103 has received user identification information relating to the user, information regarding whether the user is present or away and / or the fixture 2 or the article Alternatively, since the information processing apparatus 7 or the electronic data further includes presence information determination means 107 that generates presence information including information on the usage status and state of at least one of the electronic data, It is possible to record the usage status of the furniture 2, the article, the information processing device 7, or the electronic data by the user.

Since the presence information output means 108 for outputting the presence information generated by the presence information determination means 107 is further provided, whether there is a user in the current workspace, the fixture 2, the article, or the information processing apparatus 7. It is possible to notify other users whether or not the information has been illegally operated.
Since the user identification information transmitting unit 102 and the user identification information receiving unit 103 communicate with each other wirelessly, the convenience of the guard system 1 is further improved.

  The distance at which the user identification information relating to the guest user can be transferred between the user identification information transmitting means 102 and the user identification information receiving means 103 is set shorter than the distance at which the user identification information relating to the owner user can be transferred. Therefore, it is possible to avoid the inconvenience that the security function for some fixtures 2 and the like is unnecessarily released simply by the guest user accidentally passing the vicinity of the owner user's workspace. It becomes.

  Request signal transmitting means 114 for transmitting a request signal for causing the user identification information transmitting means 102 to transmit user identification information; and a request signal receiving means 115 for receiving a request signal transmitted from the request signal transmitting means 114. In addition, when the request signal transmitting unit 114 transmits the request signal, the request signal receiving unit 115 receives the request signal, and the user identification information transmitting unit 102 receives the request signal. Since the identification information is transmitted, the user identification information transmitting unit 102 transmits the user identification information only in the area where the request signal transmitting unit 114 exists. That is, the user identification information transmitting means 102 is released from the necessity of constantly transmitting user identification information, and the amount of power consumed by transmitting user identification information can be suppressed.

  In addition, when the approach detection means 113 detects that some person has approached the furniture, the article or the information processing apparatus, and when some approach is detected via the approach detection means 113, the user identification information A request signal transmitter 114 for transmitting a request signal for causing the transmitter 102 to transmit user identification information; and a request signal receiver 115 for receiving a request signal transmitted from the request signal transmitter 114; When the request signal transmitting unit 114 transmits the request signal, the request signal receiving unit 115 receives the request signal. Based on the reception of the request signal, the user identification information transmitting unit 102 transmits the user identification information. Therefore, the request signal transmission means 114 transmits the request signal only when the presence of some person is detected.Therefore, the frequency of transmitting the request signal can be reduced, and the amount of radio waves propagating in the workspace can be reduced.

  An article identification information transmitting means 116 for transmitting article identification information for identifying the article attached to the article to be supervised, and an article identification information reception for receiving the article identification information transmitted from the article identification information transmitting means 116 Means 117, article identification information storage means 120 storing article identification information related to the article, and article identification information receiving means 117 receiving article identification information not stored in article identification information storage means 120.
