  Hereinafter, the present invention will be described in detail on the basis of the embodiments. However, these embodiments are described in order to help understanding of the present invention, and are intended to limit the present invention to the described embodiments. It is obvious that there is nothing.

  In the present embodiment, the indoor position information management system and the indoor position information management method according to the present invention will be described taking a machine room in which a plurality of users enter and leave a room and a plurality of server racks as an example. To do. Further, in the present embodiment, the transmission device and the reception device are an ultrasonic transmission device and an ultrasonic reception device, and the radio waves transmitted and received between these devices are ultrasonic waves.

  The indoor position information management system according to the present embodiment includes an ultrasonic transmission device attached to an indoor position measurement target, and at least three ultrasonic waves installed in the room and capable of receiving ultrasonic waves transmitted from the ultrasonic transmission device. An ultrasonic receiving device and a processing device for obtaining position information of the ultrasonic transmitting device based on ultrasonic information received by the ultrasonic receiving device.

In the indoor position information management system, the ultrasonic transmission device is attached to each user who is a position measurement target. The ultrasonic transmission device has, for example, a name plate or card shape, and may be hung from the user's neck or pinned to clothes.
Note that the ultrasonic wave means a sound wave having a frequency of 20 kHz or higher that cannot be heard by the human ear.

  The ultrasonic receiver is an apparatus for receiving ultrasonic waves transmitted from the ultrasonic transmitter, and is installed on the ceiling of the machine room, the upper part of the wall surface, or the like. At least three ultrasonic receivers are required for measuring the position of the ultrasonic transmitter, and are installed at a predetermined distance from each other.

The processing device obtains position information of the ultrasonic transmission device based on ultrasonic information received by the ultrasonic reception device, and controls the ultrasonic reception device and the ultrasonic transmission device. An ultrasonic signal emitted from the ultrasonic transmitter is received by a plurality of ultrasonic receivers to measure a three-dimensional position.
The processing device may include a distance measurement subsystem, a wireless ultrasonic transmission device control device, a data collection processing unit, a data processing device, and the like, which will be described later.

  In the indoor location information management system, when the processing device measures the position of the user, the processing device specifies and controls the ultrasonic transmission device by the ID of the identification information, controls the reflection timing of the ultrasonic signal, and is emitted. The timing at which an ultrasonic signal is received by a plurality of ultrasonic receivers is measured. A three-dimensional position measurement process is performed using these signals, and the three-dimensional position data is stored as time-series data together with time information of the time at which the position information is acquired, in a position information storage unit of a processing device described later. In this case, a three-dimensional position can be specified by performing data processing using signals received by at least three ultrasonic receiving devices.

A known ultrasonic three-dimensional position measurement system (ultrasonic three-dimensional tag system) is preferably applied to the indoor position information management system. A preferable ultrasonic three-dimensional positioning system is disclosed in, for example, the above-mentioned Patent Document 1.
The ultrasonic three-dimensional position measurement system is a tertiary that includes an ultrasonic receiver installed in a space for measurement and an ultrasonic transmitter (ultrasonic three-dimensional tag) attached to a person who is a measurement target of position measurement. It is an original position measurement system, and an ultrasonic transmission device that is specified and controlled by an ID of identification information needs to be attached to a position measurement target.

  An ultrasonic three-dimensional positioning system is installed on an ultrasonic transmitter (ultrasonic three-dimensional tag) that is attached to a position measurement target and transmits an ultrasonic signal at a predetermined timing, and receives an ultrasonic signal. A distance measurement sub that measures the distance from the phase difference of the received ultrasonic signal and controls the ultrasonic transmission device to perform ultrasonic radar measurement when the ultrasonic transmission device is connected A system, a wireless ultrasonic transmitter control device that controls the timing of transmitting an ultrasonic signal from an ultrasonic transmitter wirelessly, a data collection processing unit that collects three-dimensional position data obtained from a distance measurement subsystem, and A data processing apparatus (for example, a personal computer) that performs system control and data processing is configured.

The ultrasonic pulses transmitted from the ultrasonic transmission device are received by a plurality of ultrasonic reception devices. The ultrasonic receiving device includes an ultrasonic receiving unit and an amplifying device. The ultrasonic receiving device receives and amplifies an ultrasonic pulse, and supplies a reception signal to the distance measurement subsystem.
In the distance measurement subsystem, the time until the ultrasonic pulse emitted from the ultrasonic transmission device reaches the ultrasonic reception device is measured, and the distance therebetween is measured. By receiving ultrasonic pulses emitted from the same ultrasonic transmitter by different ultrasonic receivers, the three-dimensional position of the ultrasonic transmitter can be obtained. Each ultrasonic transmission device is controlled by being distinguished by the ID of the identification information. Data processing for obtaining a three-dimensional position is processed by a data processing device.

In the distance measurement subsystem, in the connected ultrasonic receiving device, each ultrasonic transmitting device is distinguished in order to receive the ultrasonic pulse from each ultrasonic transmitting device. The transmission timing of the ultrasonic pulse is individually controlled. That is, in the distance measurement performed by the distance measurement subsystem, the time from when the ultrasonic transmission device starts measuring the time according to the timing of transmitting the ultrasonic pulse until each ultrasonic reception device receives the ultrasonic pulse. The distance between the ultrasonic transmission device and the ultrasonic reception device is measured from the velocity of the ultrasonic wave traveling in the air. Further, when an ultrasonic transmission device is connected, the ultrasonic transmission device is controlled to perform ultrasonic radar measurement.
Therefore, a wireless ultrasonic transmission device control device is provided, and the wireless ultrasonic transmission device control device modulates the synchronization signal and the identification code ID with a high-frequency signal for each of the plurality of ultrasonic transmission devices. The transmission timing of the ultrasonic pulse of each ultrasonic transmission device is individually controlled. The wireless ultrasonic transmission device control device wirelessly transmits the identification code ID to the ultrasonic transmission device and transmits a synchronization signal to the entire system.

  The data collection processing unit collects distance information data measured by the distance measurement subsystem and transmits the collected data to the data processing device. The data processing device calculates a three-dimensional position based on distance information between the plurality of ultrasonic transmission devices and the plurality of ultrasonic reception devices.

  In the indoor position information management system, ultrasonic waves having a frequency of about 40 kHz are used, the measurement accuracy of the three-dimensional position is about 20 to 80 mm, and the measurement distance is about 50 cm to 70 m.

  In the above-described indoor position information management system, if a person's position is detected, three-dimensional information such as standing, sitting, or squatting is acquired in addition to information indicating where the plane has moved from where. Can do.

  The indoor position information management system is configured to determine whether the position measurement target is based on position information of the ultrasonic transmission device and permission area information that sets at least three types of areas that are uniquely set for each position measurement target. A warning is issued when the area is not permitted in the permitted area information, and the at least three types of areas include an intrusion prohibited area, a passable area, and a stayable area.

  In the position information management system according to the present embodiment, the position information of the user (position measurement target) is managed in real time based on the position information of the ultrasonic transmission device and the permitted area information for setting at least three types of areas. Thus, it is possible to divide the room into a stayable area and an impossible area without providing a physical restriction such as a cage in the room. In addition, it is possible to set an intrusion allowance area for each user (position measurement target) in a machine room where a plurality of users enter and leave the room.

  Therefore, by using the position information management system for management of a machine room such as a data center, it becomes possible to appropriately set an area according to the security desired by the user. In addition, it is possible to flexibly cope with a change in indoor layout and replacement of users by updating or changing the permitted area information for each user.

In the indoor position information management system, the permitted area information is set uniquely for each position measurement target, and it is preferable that at least three types of areas include an intrusion prohibited area, a passable area, and a stayable area. .
And when the position measurement object exists in the intrusion prohibited area, an immediate warning is notified, and when the position measurement object exists in the passable area, a warning is notified after a lapse of a predetermined time, and the position measurement object is Do not warn you when you are in a stayable area.

  Permitted area information is information set for each user, and includes at least an intrusion prohibited area, a passable area, and a stayable area.

  The intrusion prohibited area is the highest security area among the above three areas, and a warning is notified when it is determined that the user has entered the area. The warning is based on the alarm, the lighting of the patrol light, or the voice that notifies the user that the current area is an intrusion prohibited area for the user, and the voice output device installed in the room or the ultrasonic transmission device This is performed for a user who has entered the intrusion prohibited area by the sound output from the sound output unit. The time from when the user enters the area until the warning is notified is preferably 0 to 2 seconds in order to ensure high security.

  The passable area is an area that can pass within a certain period of time but is not allowed to stay for a certain period of time. For this reason, a warning is notified if the user stays in the passable area even after a predetermined time has elapsed. The warning notifies that the current area is a passable area for the user after a certain period of time. The time from when the user enters the area until the warning is notified is preferably 5 to 10 seconds.

For example, it is preferable that an area through which many users pass such as the vicinity of the entrance of the machine room and a passage along the inner wall is set as the passable area. In this way, the layout of the machine room can be determined flexibly without impairing the convenience for the user, and the user with the server rack installed on the aisle side can also be compared with other users. Equivalent security can be provided.
In addition, for example, even if the layout in which the stayable area of the user A cannot be reached without passing through the stayable area of the other user B, the stayable area of the user B is the passable area of the user A By doing so, security can be provided to the user B as well.

  By setting such a passable area, it is possible to ensure security for each user at any position in the machine room. In addition, it is possible to flexibly cope with room layout changes and user replacement.

  The stayable area is an area where the user can stay without any restrictions. The stayable area is set around the server rack of the user.

  Next, the permission area will be described with specific examples. FIG. 2A shows an example of the user “Company A” who uses the server racks RA11 to RA18. Although not shown, in this example, the entrance of the machine room is provided in the area a. Therefore, the stayable area of Company A is h1, h2 and i on both sides of the server racks RA11 to RA18, the passable areas are a, b, c, m, n and o, and the other areas are prohibited entry areas. It is. The information on the permitted area for each user is managed by the following data table.

  FIG. 2B is an example of a user “Company B” who uses the server racks RA21 to RA28. As shown in the above data table, information on permitted areas different from Company A is given.

  FIG. 2C shows an example of a user “Company C” who uses the server racks RA01, 02, 33, and 34. As shown in the data table, in addition to the passage along the inner wall of the machine room, g2, j1, j3, k1, and k3 that are other user's stayable areas are also set as passable areas.

  Moreover, the permission area information for each user may include a data table in which each area as shown in Table 2 is associated with its stayable time.

In addition, the data table of Table 2 may include an upper limit of the number of intrusions within a predetermined time in a restricted area such as an intrusion prohibited area or a passable area. By detecting repeated intrusions into the intrusion prohibited area and the passable area, it is possible to issue a warning by determining that a user who passes through or enters the restricted area many times within a predetermined time is a suspicious person.
The number of repeated intrusions in the restricted area is preferably stored as a data table as shown in Table 3.

  In addition, the permission area information for every user including the said data table may be memorize | stored in the permission area information storage part of an ultrasonic transmitter. Alternatively, the permissible area information for each user and the management information such as the data table are stored in a storage device provided in the processing device or a storage device such as a data server provided outside the processing device. Also good.

The processing apparatus includes a position information calculation unit that calculates position information of a position measurement target based on ultrasonic information received by the ultrasonic reception device, and a position information storage unit that stores position information. It may be.
Then, the position information calculation unit calculates the movement history information of the position measurement object based on the position information and the time information of the time when the position information was acquired, and stores the movement history information in the position information storage unit. Also good.

  As described above, the movement history information of the position measurement target can be managed by calculating the movement history information of the position measurement target based on the position information and the time information and storing it in the position information storage unit.

In the machine room, a self-propelled camera may be provided on the ceiling or the like. By using the history information and the image information of the self-propelled camera together, it is possible to specify in more detail illegal behavior in the machine room. Alternatively, by linking the movement history information and the operation of the self-propelled camera, it is possible to record image information only for users who perform suspicious behavior.
Further, since the tracking operation by the self-propelled camera also acts as a threatening action against a suspicious user, it is possible to prevent unauthorized actions.

Each self-propelled camera can specify the area to be monitored based on the permitted area information. In particular, it is possible to automatically take a picture and record information about the area where the warning is notified.
The self-propelled camera can take an image of any measurement object based on the position information of the measurement object by the position information calculation unit, and record the action record. In this case, for example, as shown in Table 4, the camera movement distance from the initial position, the horizontal angle of the camera direction with respect to the traveling direction, or the vertical angle is designated for each camera in the shooting area (area).

  By recording the indoor position information management system according to this embodiment and a plurality of self-propelled cameras installed in the room, a record of the situation in the machine room or a record of the behavior of the user notified of the warning It is preferably used for equipment such as a server room where a certain degree of freedom is required while emphasizing security.

  Next, an example of machine room management using the location information management system according to the present embodiment will be described with reference to the usage flow of FIG.

First, the user confirms the identity of the user at the reception of the data center or machine room by palm vein authentication or the like (s100). In the entrance / exit management system, the entrance location information including information such as the user's rack number is confirmed (s102), and the information is passed to the location information management system (s104). The room entry location information includes rack information as shown in Table 5.
The information may be written on an ID card lent to the user (s106).

  The location information management system writes the permitted area information corresponding to the room entry location information in the SS tag (three-dimensional ultrasonic tag) lent to the user (s108).

  The user enters the server room (machine room) by palm vein authentication or ID card authentication (s110). When the user enters the server room, the location information management system starts monitoring the user's behavior (s112).

  Although the user is automatically monitored based on the above-mentioned permitted area information (s114), the indoor situation may be confirmed from the monitoring room by a self-propelled camera installed in the server room room. .

In the server room room, when an unauthorized action of the user is confirmed (s116), for example, when the user enters the prohibited area for user entry, a warning is notified to the user.
At this time, the monitoring room is also notified, and information on the violator who has performed the illegal behavior is displayed on a terminal in the monitoring room (s118, s120). Simultaneously with the notification to the monitoring room, the action is confirmed and recorded by the self-propelled camera installed in the server room (s122).

  In addition to entering an intrusion prohibited area or staying in a passable area, fraudulent behavior includes cases where the SS tag is intentionally hidden to make it unreceivable, or when the user removes the SS tag. .

When it is confirmed that the user has left the room due to the authentication of the ID card (s124), if the position information management system does not confirm that the user has left the room, monitoring of illegal behavior is continued (s126). If the location information management system confirms that the user has left the room, the user's dynamic monitoring is terminated (s128).
Thereafter, the user returns the ID card and the SS tag (s130, s132).

  The ID card and the SS tag may be separate as in this example, or may be a single one having both functions.

  In addition, for example, a portable display device (electronic paper, liquid crystal display device, etc.) is lent to the user, and the permitted area information and the position information of the server rack used by the user are displayed on the display device. You may do it. In this way, the user can grasp the current position of the user and information on the permitted area, and can prevent the user from entering the restricted area by mistake.

  In the above embodiment, the indoor position information management system using ultrasonic waves has been described. However, as described above, the radio waves used in the indoor position information management system and the indoor position information management method of the present invention are ultrasonic waves. However, the transmission apparatus and the reception apparatus are adapted to the radio waves used.

  For example, as a technology that can measure three-dimensional position information, the “Mojix STAR System (reading ultra far-distance Gen2 tag + high-precision position information)” of Moix (USA), which uses a phased array antenna as a receiving device, is adopted. May be.

In the above “Mix STAR System”, a phased array antenna is employed as an antenna so that reception signals can be amplified and noise can be removed at a high level. Furthermore, STAR, which is a signal receiving antenna, and eNodes, which is a power supply antenna, are separated so that noise due to power supply does not interfere with signal reception.
In addition, since “Mojix STAR System” can acquire the three-dimensional position information of the tag (RFID tag) with an accuracy of a radius of 30 centimeters, it can be preferably used in the indoor position information management system according to the present invention.

As described above, according to the present invention, it is possible to manage the position information of the position measurement object in the room, and the area where the room can stay and the area where the room can not be stayed without physical restrictions. There are provided an indoor position information management system and an indoor position information management method that can be divided into two, and an intrusion allowance area can be set for each position measurement target.
