[Problems to be solved by the invention]
However, in the first prior art, the determination of whether or not the behavior is suspicious ultimately depends on the visual observation of human beings. Therefore, when a large number of cameras are installed in a wide space or a large number of monitoring targets exist, it is not sufficient. Cannot monitor.
[0011]
Further, in the second related art, it is difficult to track a suspicious person present in a crowded place by an image.
[0012]
In the third conventional technique, a position measurement system using GPS, PHS, or the like is not suitable for measurement in a narrow closed space such as a building because the position detection accuracy is not so good.
[0013]
Further, in the fourth and fifth prior arts, that is, in the security system as a gate, it is impossible to monitor the behavior of a visitor after passing through the gate. Further, there is no known monitor that performs monitoring based on personal information. Further, in the fourth prior art and the fifth prior art, when it is necessary to partition an area where access is restricted by a wall or the like, or if a flexible access possible area is set for each person, a large number of locks are required. There is a problem that it is impractical in terms of cost and load on the user, and a heavy load on the user such as taking out a card or inputting a personal identification number. Further, in the entry restriction by the lock of the door, it is impossible to check the position or the like of the entrant after that when the vehicle is intruded while the door is unlocked or once entered. In addition, even if only authorized persons have access, it is necessary to stop in front of the door and wait for the lock to be released.
[0014]
Further, in the above-mentioned sixth prior art, it is not possible to perform fraud simply by cutting off an alarm of a mobile wireless device, and it is not possible to control the authority of a person who has performed fraud on the server side. It was not possible to change the authority flexibly according to. Further, in the sixth prior art, when the mobile radio device is destroyed or discarded, there is a disadvantage that it is difficult to limit the subsequent operation.
[0015]
In addition, any of the above-described conventional techniques cannot predict a person who is likely to commit wrongdoing and use it for control of a surveillance camera, or can instruct a person who has entered an inaccessible area by mistake a direction to proceed. Did not.
[0016]
Although a system that measures the movement of a person in a room by using a wireless tag is known, a technology that applies this to security is not known.
[0017]
The present invention has been made in view of the above-described problems, and provides a monitoring system, a monitoring method, and a monitoring program that can reduce a burden on a visitor and improve the reliability of the entrance restriction. The purpose is to:

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of a monitoring system, a monitoring method, and a monitoring program according to the present invention will be described in detail with reference to the drawings. The present invention is not limited by the present embodiment.
[0028]
(Embodiment 1)
First, a monitoring system and a monitoring method according to the first embodiment will be described. The first embodiment can be applied to, for example, a monitoring system that monitors the position of a person (entry) entering an area having an area where entry is restricted, such as a business office.
[0029]
As shown in FIG. 1, for example, this monitoring system includes a wireless tag 10A carried by a visitor, a transceiver 20A and a person detection sensor 30A installed in each predetermined area in the area, a transceiver 20A and a person An information collecting unit 40A that collects information detected by the detection sensor 30A, a wall 50A provided around a predetermined area, a door 60A provided at an entrance and exit of the area, and a monitoring camera installed in the predetermined area 70A, and a monitoring server 100A that controls the state of the door 60A and the like according to the reception information of the transceiver 20A and the detection output of the human detection sensor 30A.
[0030]
The wireless tag 10A includes, for example, a so-called RF-ID (Radio Frequency Identification) or the like configured as illustrated in FIG. 2 and different identification information (TID) for each wireless tag 10A. _i ) And the TID stored in the identification information holding unit 11A. _i , A transmission / reception switching unit 13A comprising a directional coupler and the like for switching transmission / reception signals, an antenna 14A, and reception for receiving signals from the transceiver 20A. A light emitting unit 16A, a speaker 17A, and a vibrating unit 18A that are driven according to control information and the like in a received signal. The light emitting unit 16A includes light emitting elements such as LEDs of a plurality of colors (red, yellow, blue, or green), for example. The speaker 17A is for generating a warning sound or the like. The vibrating unit 18A vibrates the wireless tag 10A by, for example, rotating an eccentric rotating body, similarly to a so-called vibrator function used for a mobile phone terminal or the like.
[0031]
The wireless tag 10A may be configured as a single unit, but for example, the identification information holding unit 11A, the transmitting unit 12A, the transmission / reception switching unit 13A, the antenna 14A, the receiving unit 15A, etc. are integrated as a so-called PC card or the like. And the light emitting unit 16A, the speaker 17A, the vibrating unit 18A, and the like are configured as a display unit, a speaker, a vibrating unit, and the like of a portable information terminal such as a PDA (personal digital assistant) connected to a PC card or the like. Is also good.
[0032]
The transmission unit 12A is configured to transmit the TID stored in the identification information storage unit 11A. _i , And transmits the transmission signal via the transmission / reception switching unit 13A and the antenna 14A.
[0033]
This wireless tag 10A is TID _i Is determined according to the moving speed of the resident and the arrangement interval of the transceivers 20A. For example, when moving in a normal building by walking, it is about once every few seconds. Alternatively, when the user walks in the event venue, the arrangement interval of the transceiver 20A is narrowed and the TID is reduced. _i Therefore, the accuracy of detecting the position of the entrant can be improved by shortening the interval at which the signal is transmitted according to. The transmission interval is determined by the transmitting unit 12A by the TID. _i Can be adjusted by controlling the signal transmission interval according to Thus, TID _i By adjusting the signal transmission interval according to the above, it is possible to contribute to a reduction in the power consumption of the wireless tag 10A as compared with a case where the signal is transmitted more frequently than necessary.
[0034]
Further, on the surface of the wireless tag 10A, a different identification display is provided for each wireless tag, for example, by optically readable OCR characters, bar codes, or the like. In the monitoring server 100A, for example, the identification display and the TID _i And an input device for inputting entry restriction information and the like corresponding to the identification information. In addition, the identification display is TID _i Identifier and TID _i May not be provided.
[0035]
The transceiver 20A receives the transmission signal transmitted from the wireless tag 10A as described above, and identifies the identification information TID in the received signal. _i Is extracted and transmitted to the information collecting unit 40A. The transceiver 20A is installed at a predetermined interval in a predetermined area such as a building including an area where access is restricted, as shown in FIG. 3, for example. Although not shown, a human detection sensor 30A is provided for each area where the transceiver 20A is installed.
[0036]
The reception sensitivity of each transceiver 20A is adjusted to such an extent that the wireless tag 10A in the area corresponding to each transceiver 20A can be detected. However, since the individual areas cannot be completely separated, the receivable range of the transceiver 20A partially overlaps, for example, as shown in FIG. Therefore, a plurality of transceivers 20A may receive signals from the same wireless tag 10A. In such a case, it is assumed that the wireless tag 10A is located in an area corresponding to any one of the transceivers 20A. However, as will be described later, in the processing up to the determination of the state, the wireless tag 10A can be treated as being present in a plurality of areas.
[0037]
The monitoring server 100A described later has the same function as the transceiver 20A, and the TID of the wireless tag 10A by itself is used. _i May be read.
[0038]
The human detection sensor 30A is provided for each predetermined area in the area as described above, and detects, for example, infrared rays, sound, weight, or radio waves emitted from a device such as a mobile phone carried by an entrant in the area. To detect whether there is a person in the area. Alternatively, the presence or absence of a person may be detected based on an image from a video camera or the like.
[0039]
Also, instead of using the output of the human detection sensor 30A, the detection of the entrant holding the wireless tag 10A can be performed by using the detection output indicating whether or not the transceiver 20A has received the radio wave from the wireless tag 10A. Is possible, but by providing the human detection sensor 30A separately from the transceiver 20A, it is possible to detect a person who does not carry the wireless tag 10A. Therefore, the human detection sensor 30A is provided separately from the transceiver 20A. It is desirable.
[0040]
The information collecting unit 40A collects the identification information from each transceiver 20A and the detection output of each person detection sensor 30A, and transmits the collected information to the monitoring server 100A at predetermined time intervals. The information transmitted by the information collecting unit 40A to the monitoring server 100A includes, for example, identification information (RID) indicating an area where each transceiver 20 is installed, as shown in FIG. _j ) And the identification information TID of all the wireless tags 10A from which the transceiver 20A installed in the area has received the signal. _i And a table indicating the correspondence between information (sensor output, for example, 0: none, 1: present) indicating the detection output of the human detection sensor 30A installed in the area. In the table shown in FIG. 5, the identification information TID of the same wireless tag 10A is used. _i Is multiple RIDs _j Is shown, the identification information TID of the same wireless tag 10A is shown. _i Is any RID _j Information collection unit 40A is configured to use any of the RIDs _j May be selected.
[0041]
The wall 50A is provided around a predetermined area. From the viewpoint of reducing the processing load by reducing the situation where a plurality of transceivers 20A receive signals from the same wireless tag 10A by separating individual areas, the wall 50A can cut off radio waves from the wireless tag 10A. It is desirable to configure with the material and thickness. However, since it may be difficult in practice, it is not always necessary to provide the wall 50A for every area as in the areas other than the areas r6 to r8 and r16 to r18 in FIG.
[0042]
It is desirable that the door 60A be configured to be able to block radio waves from the wireless tag 10A, similarly to the wall 50A. However, even when the radio waves cannot be completely blocked, the position of the wireless tag 10A can be changed by the processing described below. Since the determination can be made, the radio wave does not have to be completely cut off.
[0043]
The installation position of the transceiver 20A may be determined according to the radio wave blocking characteristics of the wall 50A and the door 60A. For example, when the radio wave blocking characteristic of the door 60A is poor, if the transceiver 20A is installed on the wall surface above the door 60A, the transceiver 20A becomes difficult to receive the radio wave of the wireless tag 10A from outside the door 60A, and the wall 50A It becomes easy to receive only the radio wave from the wireless tag 10A in the area surrounded by the door 60A.
[0044]
Further, the door 60A, which may prevent an intruder from entering, is provided with a receiving unit 61A that receives a control signal from the monitoring server 100A, and a lock mechanism 62A that locks opening and closing according to the control signal.
[0045]
The monitoring server 100A communicates with an auxiliary storage device such as a processor (MPU), a memory, a hard disk drive (HDD), an input device such as a keyboard, an output device such as a display device or a printer, and the information collecting unit 40A. It can be composed of an information processing device such as a personal computer or a workstation having a communication interface or the like.
[0046]
The monitoring server 100A includes, for example, a receiving unit 101A that receives information from the information collecting unit 40A when the MPU executes a predetermined control program, and a position that holds the position of each wireless tag 10A that is received by the receiving unit 101A. A holding unit 102A, a history holding unit 103A for holding a history of the position of each wireless tag 10A for a predetermined time, a sensor output holding unit 104A for holding the detection output of each person detection sensor 30A received by 101A, Entry restriction information input unit 112A composed of an input device such as a keyboard and a pointing device for inputting information (entry restriction information) indicating the entry restriction information for each attribute of the attribute, and an entry restriction information holding unit for holding the entered entry restriction information 111A, an identification display reading unit 110A that reads the identification display of the wireless tag 10A, and the position and wear of each wireless tag 10A. A determination unit 120A that determines whether or not a process such as locking of the door 60A is required according to the sensor output, the entry restriction information, and the like, and an output unit 130A that controls the operation and the like of the lock mechanism 62A according to the determination result. Function as Note that a similar configuration can be configured by hardware.
[0047]
The output unit 130A includes a door control unit 131A that controls the lock mechanism 62A, a security instruction unit 132A that displays instructions for security personnel, an instruction transmission unit 133A that transmits instructions to the wireless tag 10A, and an operation of the monitoring camera 70A. And a camera control unit 134A for controlling.
[0048]
・ Entry restriction information setting processing according to the attribute of the visitor
In the monitoring system configured as described above, first, the entry restriction information according to the attribute of the visitor is set. The entry restriction information is set for each attribute of the visitor by using, for example, an attribute table shown in FIG.
[0049]
This attribute table is initialized to 0 (unset state), for example, when the system is started up. After the initialization, it is determined whether or not to permit entry into each area for each attribute (customer, facility staff, facility senior staff, security manager, part-time job staff, visitor, etc.) via the entry restriction information input unit 112A. Enter the information shown. For this input, the value of the attribute table shown in FIG. 6 may be directly input. For example, as shown in FIG. 7, an image 201A indicating the area within the area is displayed, and the operator enters the entry restriction information input section 112A. When the pointer 202A is moved by the operation of the pointing device and a button provided for each area is instructed, for example, as shown in FIG. 8, selectable states (for example, "entry permitted", "entry prohibited") Is displayed, and the value corresponding to the state instructed by the operator (for example, “1” for “entry permitted”, “2” for “entry prohibited”, etc.) is described above. Is the entry restriction information of the area in the attribute table. Such entry restriction information is input for each attribute, and an attribute table as shown in FIG. 6 is configured corresponding to the identification information of each attribute. For attributes other than the visitor, only the area of “no entry” may be input, and the other areas may be automatically set to “permission”.
[0050]
If the visitor is a visitor, determine a general restricted area in advance, enter the destination (destination) such as a meeting room, product delivery location, etc. for each individual visitor, and go to the possible destination. The shortest route that does not pass through the no-go zone may be determined from among the routes described above, and the zone on the shortest route may be set as the no-go zone. As the shortest route, the operator may input the shortest route, or may input only the destination and automatically obtain the shortest route. When the input route passes through the restricted area, the input of the route may be requested again.
[0051]
Here, the path length is the sum of the weights assigned to the paths, and when this weight is a distance, the path length is a distance along the path. Further, in addition to the distance, the amount of risk when traveling along the route may be used as the weight. In the present embodiment, the path with the shortest path length determined in this way is called the shortest path.
[0052]
In addition to the shortest route, a predetermined route that can be taken, for example, a route that is 1.3 times or less the route length of the shortest route and does not pass through the no-go zone is also added to the no-go zone. You may make it.
[0053]
When the entry restriction information is set as described above, the state of each area for each attribute is classified into entry prohibition “2”, entry permission “1”, and unset “0”.
[0054]
・ TID of wireless tag 10A carried by the visitor _i Registration process for attribute
When a visitor enters the area, the association between the wireless tag 10A carried by the visitor and the attribute is set. Specifically, the identification display of the wireless tag 10A to be carried by the visitor is read by the identification display reading unit 112A, and the identification information TID corresponding to the read identification display is read. _i To get. Further, the attribute, name, and the like of the entrant are input via the entry restriction information input unit 110A. The input attribute, name, etc. are, for example, as shown in FIG. 9, the identification information TID of the wireless tag 10A. _i And is stored in the entry restriction information holding unit 111A as a person table.
[0055]
When registered in the entry restriction information (attribute table) and the person table, the registered entrant can enter the area.
[0056]
・ Visitor position monitoring
The signal from the wireless tag 10A carried by the entrant who has entered the area is received by the nearby transceiver 20A, and the position of the received transceiver 20A is regarded as the entrant's position. The information collecting unit 40A includes identification information TID of the wireless tag 10A from which all the transceivers 20A in the area have received the signal. _i Is transmitted to the receiving unit 101A of the monitoring server 100A at predetermined time intervals, for example, as data as shown in FIG. 5 described above.
[0057]
Upon receiving such data, the receiving unit 101A receives, for example, the RID _j And TID _i Is supplied to the position holding unit 102A, and the RID _j Is supplied to the sensor output holding unit 104A. When new data is supplied, the position holding unit 102A supplies the data that has been held up to the history holding unit 103A, and the history holding unit 103A discards the data that has been held so far and discards the data that has been held so far. Holds the data supplied from. Thereby, the history holding unit 103A holds the data within a predetermined time in the past, that is, the history of the past position of each wireless tag 10A.
[0058]
The determination unit 120A checks the sensor output of the individual detection sensor 30A held in the sensor output holding unit 104A at predetermined time intervals, and determines the RID whose sensor output is “1”. _j Is selected (step SA1 in FIG. 10). RID whose sensor output is "1" _j If not, after waiting for a predetermined time (step SA5), the processing from step SA1 is executed again.
[0059]
In this embodiment, in step SA1, the sensor output is checked, and the RID corresponding to the sensor is checked. _j However, the present invention is not limited to this. _j May be monitored.
[0060]
RID _j Is selected, the determination unit 120A determines the selected RID _j All TIDs corresponding to _i It is determined whether the entry restriction information corresponding to “2” is “2” indicating “entry prohibited” (step SA2).
[0061]
If the entry restriction information is “2”, the TID _i Is executed, the warning process is executed (step SA3). Here, even though the sensor output is “1”, the RID of the area is _j TID for _i The warning process is executed even when the is not registered. This is because it is considered that a person who does not carry the wireless tag 10A is in the area.
[0062]
If the entry restriction information is not "2", no warning is required, so all the selected RIDs _j It is determined whether or not the process has been completed (step SA4). _j The process from step S2 is executed, and if completed, after waiting for a predetermined time (step SA5), the process from step SA1 is executed again.
[0063]
The warning process in step SA3 includes, for example, locking of the door 60A by the lock mechanism 62A, transmission of an instruction to the wireless tag 10A, output of a security instruction to a security guard, control of the monitoring camera 70A, and the like.
[0064]
The locking of the door 60A by the lock mechanism 62A is performed, for example, on the receiving unit 61A corresponding to the door 60A near the current position of the entrant to be warned and capable of entering the area where the entrant is prohibited from entering. Then, the door control unit 131A transmits a control instruction, and the receiving unit 61A that has received the control instruction locks the door 60A by the corresponding lock mechanism 62A.
[0065]
The transmission of the instruction to the wireless tag 10A is performed by transmitting an instruction to generate a warning sound, vibration, or the like from the instruction transmitting unit 133A to the wireless tag 10A carried by the resident as a warning target.
[0066]
The output of the security instruction to the security guard is performed by the security instruction unit 132A by the TID of the wireless tag 10A carried by the entrant to be warned. _i (Or the corresponding name, etc.) and RID indicating the current location of the entrant _j (For example, the corresponding area name) is displayed.
[0067]
Further, the control of the monitoring camera 70A is performed by, for example, starting the imaging of the monitoring camera 70A or monitoring the monitoring of the monitoring camera 70A when the current position of the visitor to be warned is near the installation of the monitoring camera 70A This is executed by processing such as displaying the image output of the camera 70A.
[0068]
The above warning process may be executed in combination with a plurality of processes, or any one may be selected according to the situation. For example, when entering a restricted area, a security instruction is given by the security instruction unit 132A and a warning sound is generated for the wireless tag 10A. For example, when the vehicle stays in an unset area for more than 3 minutes, a security instruction is issued by the security instruction unit 132A and an alarm sound is generated for the wireless tag 10A. This is because there is no problem when passing through an unset area, but a warning may be required when staying at the same position.
[0069]
Also, in step SA3 described above, even though the sensor output is “1”, the RID of the area is _j TID for _i Is not registered, that is, in a warning process performed when a person who does not carry the wireless tag 10A is detected, it is considered that the detected person does not carry the wireless tag 10A. Instruct security.
[0070]
In this surveillance system, unlike the normal entrance control using a gate or the like, if there is any one person who is prohibited from entering the area, a warning process such as locking the door 60A is executed. Can be prevented from entering an area where entry is prohibited together with a permitted visitor.
[0071]
By the way, for example, in the conventional device shown in Patent Document 4 and the like, when a mobile radio device enters an area where entry is prohibited, a transmission signal of a fixed radio station installed in the entry-exempt area is provided. The mobile radio detects that it is in the restricted area according to the identification information inside, and a warning is issued by the mobile radio, so that the mobile radio may be left in the restricted area, for example. No warning is issued in case of destruction.
[0072]
On the other hand, in the present monitoring system, the position of the resident is always grasped by the transmission signal from the wireless tag 10A, and whether or not the area is a restricted area is determined on the monitoring server 100A side. In addition, since the human detection sensor 30A is provided separately, a warning process is always performed when the wireless tag 10A is left or destroyed, so that the reliability of the on-site monitoring can be improved.
[0073]
According to the present system, the position history (flow line) of the wireless tag is analyzed, and by detecting that the flow line is stagnant at a predetermined position or the flow line is unnaturally interrupted, the wireless tag is detected. If a tag is left or destroyed, it can be detected. Further, by monitoring the flow line in this way, the place where the wireless tag has been left or destroyed is specified, and the detection sensor or the monitoring camera installed at the specified place or in the vicinity of the specified place. The situation may be confirmed by moving the waiting detection sensor or monitoring camera to the location.
[0074]
Further, in this monitoring system, since the attributes of individual visitors are managed on the monitoring server 100A side, it is easy to change the attributes of the visitors according to the situation (for example, the number of warnings of the visitors). is there.
[0075]
Further, in this monitoring system, warning processing other than the locking of the door 60A can be selected, so that entry can be restricted without enclosing the off-limits area with the wall 50A, the door 60A, or the like. For example, when a warning sound, vibration, or the like is generated in the wireless tag 10A when approaching a restricted area, or when security is instructed by the security instruction unit 132A, the wall 50A, the door 60A, and the like may be omitted. Restrictions on access can be made.
[0076]
In the above description, the necessity of the warning is determined using the current position of the wireless tag 10A. However, the history of the warning may be managed for each wireless tag 10A. This makes it easy to identify a visitor who has many warnings (ie, a suspicious visitor). In this case, the positions of all the wireless tags 10A are displayed in the image in the area as shown in FIG. 7 described above, and the wireless tags 10A that have performed the warning process a predetermined number of times (for example, three times) are displayed. By displaying the information in a display mode different from that of the wireless tag 10A of the entrant (for example, changing the color or blinking), the presence and position of the suspicious entrant can be easily recognized. Further, for example, the position of the wireless tag 10A that has performed the warning process a predetermined number of times or more may be controlled so that the monitoring camera 70A preferentially captures an image.
[0077]
Further, a warning process according to the history of the position of the wireless tag 10A may be executed. For example, when a visitor who is prohibited from entering a predetermined area is approaching the area, a warning process such as locking the door 60A is performed first. It may be too late to execute the warning process after entering the area where entry is prohibited. However, by executing the warning process first according to the history of the position of the wireless tag 10A, it is possible to ensure the warning. The processing can be executed.
[0078]
In the above description, the states indicating the entry restriction of each area are three types of entry permitted, entry prohibited, and unset, but more states may be set.
[0079]
The receivable area of each transceiver 20A partially overlaps as shown in FIG. 4 described above. However, when a plurality of transceivers 20 receive a signal from the same wireless tag 10A, It may be determined in advance whether or not the area belongs to the area.
[0080]
In this case, in order to prevent inconsistency in the setting of the state indicating the entry restriction, the strength of each area is ordered. For example, if the strength is set in the order of entry prohibited> access permitted> unset, the positions of the wireless tags 10A belonging to a plurality of areas at the same time are determined as follows.
[0081]
1. Wireless tag 10A belonging to an area where entry is prohibited, entry is allowed, and is not set ⇒ area where entry is prohibited
2. Wireless tag 10A belonging to restricted area and restricted area ⇒ restricted area
3. Wireless tag 10A belonging to an off-line and unset area ⇒ off-limits
4. Wireless tag 10A belonging to an area where access is permitted and not set
In addition, for example, setting such as “prohibition of entry> permission of entry, permission of entry> not set, not set> prohibition of entry is prohibited because it causes inconsistency.
[0082]
In this way, by setting the priority when the position of the wireless tag 10A belongs to a plurality of areas, even if the receivable areas of the transceiver 20A overlap, the wireless tags 10A belong to any area. Can be treated as
[0083]
Further, in the monitoring system according to the first embodiment, route guidance (navigation) can be further provided to the entrant.
[0084]
In this case, as shown in FIG. 11, for example, the wireless tag 10A integrally includes the identification information holding unit 11A, the transmission unit 12A, the transmission / reception switching unit 13A, the antenna 14A, the reception unit 15A, and the like as a PC card, and emits light. The unit 16A, the speaker 17A, the vibrating unit 18A, and the like are configured as a display unit (light emitting unit 16A), a speaker, a vibrating unit, and the like of a portable information terminal such as a PDA (Personal Digital Assistant) connected to a PC card or the like.
[0085]
In addition, the monitoring server 100A is provided with a path instruction unit 140A that transmits path information to the wireless tag 10A. The route instructing unit 140A generates a map in the area and information indicating the position of the wireless tag 10A held in the position holding unit 102A, and transmits the information to the wireless tag 10A via the information collecting unit 40A.
[0086]
This information is supplied to the receiving unit 15A via the transmission / reception switching unit 13A. The receiving unit 15A controls the display by the light emitting unit 16 according to the received information. As a result, as shown in FIG. 11 described above, an image indicating the map 161A of the area, the route 162A, the off-limits area 163A, the current position 164A, the direction 165A, and the like are displayed on the display unit 160A.
[0087]
In order to display the direction, the wireless tag 10A is provided with a means for detecting the direction, for example, a gyroscope, a geomagnetic azimuth sensor, etc., and the image data of the direction 165A indicating the direction according to the detection output of this direction detection function. It is necessary to provide a function to generate
[0088]
Further, the display of the direction 165A or the like is blue when the vehicle is heading for the destination (outbound route) or the exit (return route), yellow when the vehicle is heading other than this, and red when the vehicle is heading for a restricted area. The person can easily recognize the route. In addition, the route guidance in such a form can be displayed by using the light emitting unit 16A including an LED or the like, instead of the PDA.
[0089]
As described above, in this monitoring system, the resident can easily recognize the route.
[0090]
In the above-described first embodiment, an example in which the present invention is applied to a monitoring system that monitors the position of a visitor has been described. However, the technical idea of the present invention is not limited to this. The present invention can also be applied to entrance control or the like according to the position of a visitor in an area where there is no partition between the sections.
[0091]
(Embodiment 2)
Next, a monitoring system and a monitoring method according to the second embodiment will be described. In this description, it is assumed that a person to be monitored such as a visit in a venue such as an event is monitored.
[0092]
As shown in FIG. 12, for example, this monitoring system includes a wireless tag 10B carried by each visitor and identification information (TID) of a wireless tag carried by each visitor. _i ) And the visitor information management unit 20B that associates and manages the visitor's personal information and the like, the wireless tag position measurement unit 30B that measures the position of each wireless tag 10B, and monitoring that controls the operation of the management camera 40B. A camera control unit 50B and a venue monitoring device 100B that automatically determines the attributes of the visitors according to the visitor's personal information, the position of the wireless tag 10B, etc., and displays the position of the behavior suspicious person and the like, the display of the flow line image, and the like. It has.
[0093]
The wireless tag 10B is made of, for example, a so-called RF-ID, and as shown in FIG. 13, different identification information (TID) differs for each wireless tag 10B. _i ), And the TID held in the identification information holding unit 11B. _i And a transmission antenna 13B for generating a transmission signal of a predetermined frequency corresponding to the transmission frequency. The transmitting unit 12B is configured to transmit the TID held in the identification information holding unit 11B. _i Is generated and transmitted via the transmission antenna 13B.
[0094]
This wireless tag 10B is TID _i Is determined according to the moving speed of the visitor and the arrangement interval of each receiver 31B of the wireless tag position measuring unit 30B. For example, when moving by walking in a normal building, it takes several seconds. About once per day. Alternatively, when moving within the venue by walking, the arrangement interval of the receivers 31B is narrowed and the TID is reduced. _i Therefore, the accuracy of detecting the position of the visitor can be improved by shortening the interval for transmitting the signal corresponding to. The transmission interval is determined by the transmission unit 12B by the TID. _i Can be adjusted by controlling the signal transmission interval according to Thus, TID _i By adjusting the signal transmission interval according to the TID, the TID _i , It is possible to contribute to a reduction in power consumption of the wireless tag 10 </ b> B as compared with a case where a signal corresponding to the wireless tag 10 </ b> B is transmitted.
[0095]
Further, on the surface of the wireless tag 10B, a different identification display is provided for each wireless tag, for example, by optically readable OCR characters, bar codes, or the like. For example, the identification information and the TID _i Holding means (not shown) for holding a table showing the correspondence between the two, a reading unit 22B capable of reading an identification display, an input unit 21B for inputting personal information of a visitor, and the like. Of the wireless tag 10B carried by the person _i There is provided a visitor data storage unit (visitor DB) 23B which is held in association with. In addition, the identification display is TID _i Identifier and TID _i May not be provided. In addition, the visitor's personal information may be collectively managed by the venue monitoring device 100B.
[0096]
The wireless tag position measuring unit 30B includes, for example, a receiver 31B that receives a radio wave from the wireless tag 10B and identification information (TID) of the wireless tag 10B received by each receiver 31B. _i ) And the collected TID _i And a transmitting unit 33B for transmitting the event to the venue monitoring device 100B.
[0097]
For example, as shown in FIG. 14, the receivers 31B are installed in predetermined areas (r0, r1, r2,...) In the venue, and receive the transmission signal transmitted from the wireless tag 10B as described above. And the identification information TID in the received signal. _i Is extracted and transmitted to the data collection unit 32B.
[0098]
The reception sensitivity of each receiver 31B is adjusted to such an extent that the wireless tag 10B in the area where each receiver 31B is installed can be detected. However, since it may be difficult to completely match the receiving sensitivity of the receiver 31B with the individual areas, for example, as shown in FIG. 15, the receivable range of the receiver 31B partially overlaps. Sometimes. Therefore, depending on the position of the wireless tag 10B, the plurality of receivers 31B may receive signals from the same wireless tag 10B. In such a case, the wireless tag 10B can be regarded as being in an area corresponding to any of the receivers 31B, but can be treated as being present in a plurality of areas.
[0099]
The data collection unit 32B receives the TID from each receiver 31B. _i To collect. Each of the areas r0, r1, r2,... Where the receiver 31B is installed has unique identification information (RID). _j ) Is assigned. If each receiver 31B can be identified by a communication path, for example, each receiver 31B and data collection unit 32B are connected by different wiring (communication path), the RID of each receiver 31B _j Is the TID _i Can be identified by the acquired communication path. Alternatively, as a communication path between each receiver 31B and the data collection unit 32B, for example, when a communication path that cannot physically identify the individual receiver 31B, such as a common wiring or wireless, is used, 31B is the TID of the wireless tag 10B _i With your own RID _j Is transmitted, and the data collection unit 32B transmits the RID in the data packet. _j Thus, the receiver 31B of the transmission source can be identified.
[0100]
The data collection unit 32B calculates the RID of each receiver 31B. _j And the TID obtained from the receiver 31B _i Is supplied to the transmission unit 33B in association with The transmitting unit 33B determines which TIDs at predetermined time intervals according to the information from the data collecting unit 32B. _i Is generated (position measurement output) indicating in which region the wireless tag 10B having is detected is supplied to, for example, a venue monitoring device 100B connected via a network. Which receiver 31B is installed in which area is separately managed by the venue monitoring device 100B.
[0101]
The monitoring camera 40B is installed corresponding to, for example, the areas r0, r1, r2,... Where the above-described receiver 31B is installed. The individual monitoring cameras 40B and the venue monitoring device 100B are connected, for example, via a network, and can supply the imaging outputs of the individual monitoring cameras 40B to the venue monitoring device 100B via the network. The surveillance camera 40B does not need to be installed for every area r0, r1, r2,..., But information indicating which area r0, r1, r2,. For example, it is managed by the venue monitoring device 100B.
[0102]
The monitoring camera control unit 50B is connected to, for example, a network with the venue monitoring device 100B, and controls operations such as zooming and moving the imaging direction of each monitoring camera 40B according to an instruction from the venue monitoring device 100B.
[0103]
The venue monitoring device 100B is, for example, a processor (MPU), a memory, an auxiliary storage device such as a hard disk drive (HDD), an input device such as a keyboard, a personal computer equipped with an output device such as a display device and a printer, and information processing such as a workstation. It can be composed of devices. The venue monitoring apparatus 100B includes a venue monitoring data management unit 110B that manages the history of the position of each wireless tag 10B when the MPU executes a predetermined control program, and an attribute of a monitoring target based on history information and the like. Function, and a venue monitor control unit 130B that displays a behavior suspicious individual or the like according to the determination result.
[0104]
In the HDD, a flow line DB 140B in which a history of the position of each wireless tag 10B is recorded, an image DB 150B in which images from the individual monitoring cameras 40B are recorded, general flow lines of humans, A traffic line pattern DB 160B in which an example of a suspicious person's action pattern is recorded is stored.
[0105]
The venue monitoring data management unit 110B identifies the identification information TID of each wireless tag 10B according to the information indicating the position of each wireless tag 10B supplied from the transmission unit 33B. _i Each time, for example, as shown in FIG. 16, the history of the position of each wireless tag 10B is stored in the TID. _i RID of the area where is detected _j Are stored in chronological order in association with the entry time and the departure time.
[0106]
The attribute determination unit 120B compares the number of people detected from the video imaged by the monitoring camera 40B with the number of people detected from the signal of the wireless tag 10B received by the receiver 31B at predetermined time intervals, for example, and The presence / absence of a person who does not carry is detected, and if there is a person who does not carry it, the venue monitor control unit 130B is notified (non-person carrying detection processing).
[0107]
Further, the attribute determination unit 120B determines whether the history of the position of each wireless tag 10B matches the suspicious behavior pattern stored in the suspicious behavior pattern DB 160B at predetermined time intervals, for example. TID of wireless tag 10B that matches the pattern _i Is notified to the venue monitor controller 130B (behavior suspicious individual detection processing).
[0108]
The venue monitor control unit 130B includes a monitor 131B having a display screen, a display control unit 132B that generates image data for displaying an image or the like indicating a behavior suspicious person on the monitor 131B, and image data and the like from the image DB 150B. And an image acquisition unit 133B to acquire.
[0109]
The display control unit 132B is provided for the purpose of, for example, facilitating the confirmation of the determination of the behavior suspicious individual. For example, the TID of the wireless tag 10B notified from the attribute determination unit 120B is provided. _i In accordance with the control, the image data indicating the position of the behavior suspicious person is generated, the display of the video from the monitoring camera 40B is controlled, and the like. Specifically, the display control unit 132B includes, for example, image data indicating a layout diagram indicating the size, shape, and the like of the venue as shown in FIG. 17, and the TID notified from the attribute determination unit 120B. _i Image data and the like indicating the position in the layout diagram of the wireless tag 10B corresponding to the image data, and the image acquisition unit 133B combines the image with the image and the like from the surveillance camera 40B acquired from the image DB 150B and displays the image on the display screen of the monitor 131B. Generate image data to be processed.
[0110]
The video acquisition unit 133B uses the TID notified from the attribute determination unit 120B. _i Is acquired from the image DB 150B. In the image DB 150B, the above-mentioned venue monitoring data management unit 110B stores image data of video from the monitoring camera 40B. Although there is no particular limitation on the method of recording the image data, it is desirable to record the image data in a compressed and encoded form on a disk-shaped recording medium such as a magnetic disk or an optical disk having excellent random access properties. Furthermore, if a recording method for encoding each object such as so-called MPEG-4 is used as an encoding method at the time of recording, compression encoding is performed for each object such as a background image, a person, etc. and recorded. In addition, it is possible to reduce the load of processing for extracting the person in the recorded video, detecting the movement of the person, and the like by the attribute determination unit 120B. Further, if such compression encoding is performed on the individual surveillance camera 40B side, the processing load of the venue monitoring device 100B can be reduced.
[0111]
・ Advance information registration process
In the monitoring system configured as described above, before the system starts operating, the venue monitoring data management unit 110B stores, for example, a venue layout diagram showing the physical size, shape, name, and whether or not the venue is a restricted area, The position of the receiver 31B and the respective reception ranges (corresponding to the regions r0, r1, r2,... In FIG. 14, for example), the position where the monitoring camera 40B is arranged, and the respective imaging ranges (for example, FIG. For example, information such as the area r0 for the surveillance camera 40B [C1] and r14, r13, r12, r11, and r10 for the surveillance camera 40B [C2] is set. These pieces of information are set in the venue monitoring data management unit 110B when the system is installed, and are referred to as necessary.
[0112]
・ Operation information setting processing
When the system operates, the venue monitoring data management unit 110B stores personal information for each visitor, personal information such as the visitor's name, address, nationality, criminal record, weight, and identification information TID of the wireless tag 10B. _i A table indicating the correspondence between the wireless tag 10B and the personal ID of the visitor carrying the wireless tag 10B, a history of the position of the wireless tag 10B (FIG. 16 described above), an image of each monitoring camera 40B, and the like are set. These pieces of information are also set in the venue monitoring data management unit 110B, and are referred to as needed.
[0113]
・ Non-carrier detection processing
In the non-carrier detection process described above, for example, the process shown in FIG. 18 is executed at predetermined time intervals, and the receivers 31B installed in each area are provided with TIDs. _i , The number of wireless tags 10B in the area detected from the area and the number of input tags (ie, the number of persons appearing in the video) detected from the video captured by the surveillance camera 40B are detected (steps SB1 and SB2), and these are compared. Then, the presence or absence of a person who does not carry the wireless tag 10B is determined (step SB3). When there is a person who does not carry the wireless tag 10B, a display indicating the fact is given to the venue monitor control unit 130B (step SB4). In response, the display control unit 132B displays a warning display 131a on the display screen of the monitor 131B, for example, as shown in FIG. Furthermore, an area 131c for displaying the number of persons 131b detected from the video of the monitoring camera 40B on the display screen of the monitor 131B, and identification information (TID) detected from the signal of the wireless tag 10B received by the receiver 31B. _i ) 131e, an area 131g for displaying the number of people 131f and the like may be provided.
[0114]
Further, when there is a person who does not carry the wireless tag 10B, the attribute determining unit 120B specifies the person who does not carry the wireless tag 10B with reference to the above-described history of the position of the wireless tag 10B. Is also good. Specifically, for example, as shown in FIG. 20, the characteristics of the person in the video are specified by height, clothes, color, etc., the image of each specified person is detected from the video, and the position is recorded in time series. I do. The position of the person recorded in this way is compared with the history of the position of the wireless tag 10B, and, for example, as shown in FIG. 21, those having a high degree of coincidence are associated with the person carrying the wireless tag 10B. Among the people identified from the image, those who do not have the corresponding wireless tag 10B (in this case, the person corresponding to ID “1” in FIG. 20) remain, and are identified as those who do not carry the wireless tag 10B. You.
[0115]
When a person who does not carry the wireless tag 10B is specified in this way, the attribute determination unit 120B displays information for specifying the person (for example, individual identification information [ID] or the like specified from an image) on the display control unit 132B. Notify In response, the display control unit 132B displays a display 131h indicating a person who does not carry the wireless tag 10B, for example, in the image shown in FIG. 19 described above.
[0116]
・ Suspicious behavior detection processing
In the above-described behavior suspicious individual detection process, the attribute determination unit 120B first determines whether to search for a flow line in the flow line DB 140B according to application conditions such as an area, a time zone, and the number of visitors. I do.
[0117]
When performing a search, the attribute determination unit 120B executes the process shown in FIG. 22 at predetermined time intervals, for example, and holds the position history (flow line) of each wireless tag 10 in the flow line pattern DB 160B described above. It is determined whether or not the flow line pattern is included (step SB11). If the flow line pattern is included, the TID of the wireless tag 10B of the flow line pattern is determined. _i And RID indicating the position of the wireless tag 10B _j And the like (step SB12), and the acquired TID _i , RID _j Is notified to the venue monitor control unit 130B. The venue monitor control unit 130B sends the notified TID _i , RID _j In response to the above, an instruction is given to the venue monitor control unit 130B to indicate that a person who has performed an unusual action such as a suspicious person has been found (step SB13).
[0118]
Examples of the flow line pattern held in the flow line pattern DB 160B include a pattern represented by a combination of a pattern and a condition (application condition) for applying the pattern, as described below.
[0119]
(Example 1)
Applicable condition: Entering prohibited area
Pattern: RID of restricted area set as described above in flow line DB _j TID where is registered _i Exists.
[0120]
This is the most basic pattern, and is a pattern for checking whether any person has entered the restricted area.
[0121]
(Example 2)
Applicable conditions: East venue: Morning: Number of visitors> 100 or more
Pattern: The same RID is stored in the flow line DB for a predetermined time (for example, 30 minutes). _j TID where is registered _i Exists.
[0122]
This is for checking visitors staying in the same area for a long time, and the above-mentioned application condition is, for example, when the target venue of the system is divided into the east venue and the west venue, This indicates that if the number of visitors is 100 or more in the morning only in the eastern venue, check if there is a flow line that has been staying in the same area for more than 30 minutes.
[0123]
(Example 3)
Applicable condition:
Pattern: TID that has reciprocated two or more times in a flow line DB in a predetermined time (for example, within one hour) a predetermined number of times (for example, three times) _i Exists.
[0124]
This is a pattern for checking whether or not there is a visitor making a prowl movement, and indicates that the check is always performed because the application condition is not specified. Further, if the application condition is limited to the case where the area is around the restricted area, the detection sensitivity is reduced, but the possibility of erroneous detection is reduced, and only suspicious visitors can be detected.
[0125]
(Example 4)
Applicable conditions: West venue
Pattern: TID moving in a predetermined number of areas (for example, 4 areas) within a predetermined time (for example, 10 seconds) in the flow line DB _i Exists.
[0126]
This is a pattern for detecting a fast-moving motion. In this case, an example is shown in which detection is performed only at the west venue.
[0127]
(Example 5)
Applicable condition:
Pattern: a plurality of TIDs at exactly the same position in the flow line DB for a predetermined time (for example, one hour) _i Exists.
[0128]
This is for detecting the wireless tag 10B that has been performing the same movement for a predetermined time or more. Since there is a possibility that one person holds two tags, or there is a possibility of a group with parents and children, a more detailed state can be detected by referring to personal information as described later.
[0129]
(Example 6)
Applicable condition:
Pattern: TID whose position is not registered in the flow line DB _i Exists.
[0130]
This is a pattern for detecting whether there is a wireless tag 10B that has deviated from the monitoring target area or a broken or intentionally destroyed wireless tag 10B. When this pattern is detected, the control information of the monitoring camera 40B (such as which video of the monitoring camera 40B is to be selected) cannot be given, so that the TID of the unknown wireless tag 10B is determined. _i Is simply displayed on the monitor 131B, or the TID _i RID when is detected _j Is displayed as being in the area corresponding to.
[0131]
The suspicious behavior patterns as described above generally differ depending on the venue to be monitored.
[0132]
Further, instead of simply determining the behavior suspicious individual based on the flow line, a determination condition corresponding to personal information may be defined as a flow line pattern. For example, referring to the personal information stored in the visitor DB 23B, judgment conditions for a dangerous person (for example, a person with a criminal record) and a person who is not a dangerous person are separately set, and the dangerous person is located around the restricted area. A warning may be instructed when they are gathered in the area.
[0133]
Also, even in the case of the same pattern as in Example 5, it may be necessary to make a determination by referring to personal information. Therefore, a separate determination condition is set, and when a specific flow line pattern is detected, The state is determined according to the determination condition with reference to the personal information.
[0134]
Further, in addition to the above-mentioned application conditions, personal information may be defined in association with a pattern, and for example, a security guard may be excluded from behavior suspicious persons.
[0135]
In this case, personal information can be defined. In this case, for example, the TID of the wireless tag 10B registered in the above-mentioned visitor DB 23B _i And data indicating the correspondence between the personal information and the pattern.
[0136]
In addition, when the above-described specific flow line pattern is searched in real time from the flow line DB 140B, a considerable amount of calculation may be required. Especially when comparing a plurality of flow lines, the number of combinations becomes enormous. In such a case, the venue monitoring apparatus 100B may be configured with a plurality of information processing apparatuses, and for example, the venue may be divided and processing may be performed in parallel.
[0137]
・ Display control processing
The venue monitor control unit 130B executes, for example, processing as shown in FIG. 23. In normal times (when the behavior suspicious individual is not detected), the monitor 131B displays a layout diagram showing the venue, TID of each wireless tag 10B indicating the position of the wireless tag 10B _i Is displayed. On the monitor 131B or a separately provided monitor for displaying images, for example, as shown in FIG. 24, images of all the monitoring cameras 40B are displayed. Alternatively, images from the monitoring cameras 40 </ b> B may be sequentially selected and switched and displayed.
[0138]
The venue monitor control unit 130B monitors the notification from the attribute determining unit 120B (step SB21), and when there is an instruction from the attribute determining unit 120B in step SB13 in FIG. 22 described above, the notified behavior suspicious person is notified. The display mode of the display indicating the position is changed (step SB22).
[0139]
Thereby, the display of the behavior suspicious person displayed on the monitor 131B (for example, the “TID _z ") Are displayed in a display mode different from that of a person who is not suspicious of behavior, for example, in a different display color, size, blinking state, or the like. Alternatively, a warning sound may be generated. With these displays, the operator of the venue monitoring device 100B can easily grasp the presence or absence, the position, and the like of the suspicious behavior, and can give instructions to, for example, a guard who is separately arranged.
[0140]
In step S22 described above, the display mode is changed, and (1) the flow line of the wireless tag 10B determined to be the suspicious behavior person is acquired from the flow line DB 140B and displayed. (2) Search the surveillance camera 40B showing the position of the wireless tag 10B determined as the behavior suspicious individual, and output the searched video of the surveillance camera 40B to the monitor. {Circle around (3)} The processing of controlling the movement of the imaging range, zooming and the like via the monitoring camera control unit 50B may be executed so as to image the position of the wireless tag 10B determined to be suspicious.
[0141]
Further, when the position of the wireless tag 10B determined to be a suspicious behavior is moving, the monitoring camera 40B may be controlled in synchronization with the movement, tracked, and output to the monitor. In this case, the venue monitor control unit 130B refers to the flow line DB 150B and refers to the TID of the wireless tag 10B. _i Current RID corresponding to _j , And the obtained RID _j The control is instructed to the monitoring camera control unit 50B in response to the command.
[0142]
Also, in the above (2), when a plurality of surveillance cameras 40B are searched, images of all or some surveillance cameras 40B may be displayed.
[0143]
In addition, the past flow line of the wireless tag 10B determined to be the behavior suspicious person is obtained from the flow line DB 140B, and the image from the monitoring camera 40B that is capturing the position corresponding to the obtained flow line is obtained from the image DB 150B. Alternatively, the acquired video may be displayed. This makes it easy to visually determine whether or not the user is a behavior suspicious person based on the past video.
[0144]
(Embodiment 3)
Next, a monitoring system and a monitoring method according to the third embodiment will be described. The monitoring system and the monitoring method according to the third embodiment describe a mode in which the above-described first and second embodiments are combined and operated as one system.
[0145]
FIG. 25 is a block diagram illustrating a schematic configuration of a monitoring system according to the third embodiment. As shown in FIG. 25, this monitoring system includes a wireless tag 10, a tag reader 20 (corresponding to the transceiver 20A or the receiver 31B described above) installed in each predetermined area, a relay processing device 40, and a central processing unit. The monitoring device 100 includes a monitoring device 100, a door lock mechanism 62, and a monitoring camera 70.
[0146]
The wireless tag 10 has a configuration of a so-called RF-ID tag, and is carried by a visitor. As shown in FIG. 26, the wireless tag 10 includes an identification information holding unit 11 that holds tag identification information unique to each wireless tag 10, a transmission unit 12 that generates a transmission signal indicating the tag identification information, and an antenna 14 And a receiving unit 15 for receiving a signal transmitted from the tag reader 20, a transmission / reception switching unit 13 including a directional coupler for switching a transmission / reception signal, and a warning operation unit 9 that operates according to the received signal. And a power supply 19.
[0147]
The warning operation unit 9 includes a light emitting unit 16, a speaker 17, and a vibration unit 18. The light emitting unit 16 is a light emitting element such as an LED that can emit red, yellow, blue, green, and the like. The speaker 17 outputs a sound such as a warning. The vibration unit 18 is an eccentric rotator mounted to realize a vibration function in a mobile phone terminal, for example, and is a unit that vibrates the wireless tag 10.
[0148]
The wireless tag 10 transmits the transmission signal generated by the transmission unit 12 via the transmission / reception switching unit 13 and the antenna 14 at a predetermined timing. This timing will be described later.
[0149]
In addition, a tag identification display unique to each wireless tag is provided on the surface of the wireless tag 10 by optically readable OCR characters, bar codes, or the like.
[0150]
The tag reader 20 is arranged in each predetermined monitoring area, receives a transmission signal transmitted from the wireless tag 10, extracts tag identification information from the received signal, and transmits the tag identification information to the relay processing device 40. In addition, the tag reader 20 receives various instruction signals transmitted from the relay processing device 40 to the wireless tag 10, and transmits the received instruction signal with tag identification information as a destination added thereto. The tag reader 20 is assigned reader identification information unique to each tag reader 20.
[0151]
The lock mechanism 62 is provided for each door whose access is to be restricted, and locks and unlocks the door according to a door control signal transmitted from the central monitoring device 100. Each lock mechanism 62 has door identification information DID. ₁ , DID ₂ , DID ₃ ... are assigned.
[0152]
The monitoring camera 70 is provided for each monitoring area in which the tag reader 20 is disposed, and is a means for photographing the inside of each monitoring area. In addition, the monitoring camera 70 can perform an imaging operation such as zooming and moving in an imaging direction according to a camera control signal transmitted from the central monitoring device 100, and transmits a captured image to the central monitoring device 100. Each monitoring camera 70 has camera identification information CID. ₁ , CID ₂ , CID ₃ ... are assigned.
[0153]
FIG. 27 is a diagram illustrating an example of the arrangement of the tag reader 20, the lock mechanism 62, and the monitoring camera 70. In FIG. 27, each monitoring area has a location code ZID. ₁ , ZID ₂ , ZID ₃ Are assigned, and the tag reader 20 and the monitoring camera 70 are arranged for each of the monitoring areas. Also, in FIG. 27, each tag reader 20 has the reader identification information RID. ₁ , RID ₂ , RID ₃ ... are assigned.
[0154]
Here, the receiving sensitivity of the tag reader 20 is adjusted to such an extent that the wireless tag 10 in the monitoring area corresponding to each tag reader 20 can be detected. In other words, each monitoring area is determined as a range in which one tag reader 20 can detect the wireless tag 10. However, since the detection range of the tag reader 20 is determined by a circular shape centered on the tag reader 20, the detection ranges of the tag reader 20 partially overlap to enable the detection of the wireless tag 10 over the adjacent monitoring area. It is necessary to arrange each of the tag readers 20 so that the monitoring area is determined based on the arrangement position.
[0155]
FIG. 28 is an explanatory diagram for explaining the relationship between the arrangement position of the tag reader 20 and the detection range. As shown in FIG. 28, it is preferable to adjust the reception sensitivity and the arrangement position of each tag reader 20 so that the detection range 21 of each tag reader 20 partially overlaps so that there is no area where the wireless tag 10 cannot be detected. In this case, a plurality of tag readers 20 may detect the same wireless tag 10, but the relay processing device 40 described below assigns a priority to each tag reader 20 so that any one of the tag readers 20 may be detected. It is also possible to enable only the detection of. Further, the transmission timing of the transmission signal in the wireless tag 10 can be appropriately set according to the arrangement interval of the tag readers 20. The transmission timing of the transmission signal in the wireless tag 10 can be set to about once every few seconds, for example, when the user moves by walking in a normal building, regardless of the arrangement interval of the tag reader 20. When the arrangement interval is narrow, the accuracy of detecting the position of the entrant can be improved by setting the transmission signal transmission timing to a shorter time interval. By adjusting the transmission timing of the transmission signal in the wireless tag 10 as described above, the power consumption of the wireless tag 10 can be reduced as compared with a case where the signal is transmitted more frequently than necessary.
[0156]
In FIG. 27, the wall 50 is provided around a predetermined monitoring area. This wall 50 clearly separates the individual monitoring areas, and further reduces the situation where a plurality of tag readers 20 detect the same wireless tag 10 at the same time. That is, due to the presence of the wall 50, the processing load on the tag reader 20 can be reduced. From this viewpoint, it is desirable that the wall 50 be made of a material and a thickness that can block radio waves transmitted by the wireless tag 10. In addition, as shown in FIG. 3, it is not always necessary to provide the wall 50 for every monitoring area.
[0157]
In FIG. 27, it is desirable that the door 60 has a material and a structure capable of blocking radio waves transmitted by the wireless tag 10, similarly to the wall 50. If the tag reader 20 is installed on the wall, the radio wave transmitted by the wireless tag 10 can be substantially blocked.
[0158]
In FIG. 25, the relay processing device 40 receives tag identification information from a plurality of tag readers 20 belonging to a predetermined area, adds the tag identification information of the source tag reader 20 to the received tag identification information, and adds Transmit to the monitoring device 100. This reader identification information is specified by each wiring cable when the relay processing device 40 and each tag reader 20 are connected one by one. When the relay processing device 40 and each tag reader 20 are connected by a shared wiring cable or communicate wirelessly, the tag reader 20 transmits its own reader identification information to the relay processing device 40 together with the tag identification information. In this case, the relay processing device 40 can acquire a set of the reader identification information and the tag identification information without performing the above-described processing of adding the reader identification information.
[0159]
In addition, the relay processing device 40 receives various instruction signals transmitted from the central monitoring device 100 to the tag reader 20 and the wireless tag 10, and transmits the received instruction signals to the tag reader 20, which is the destination.
[0160]
In FIG. 25, the central monitoring device 100 includes a data management unit 101, a data input unit 110, a tag identification display reading unit 112, an abnormality determination processing unit 120, a display unit 130, a door control unit 131, a security instruction, It comprises a unit 132, a warning instruction unit 133, a camera control unit 134, a route instruction unit 140, a monitoring information storage unit 105, a flow line pattern storage unit 160, and an image storage unit 150.
[0161]
The data management unit 101 receives the signal transmitted from the relay processing device 40, extracts tag identification information and reader identification information from the received signal, and stores the information in the monitoring information storage unit 105 together with the reception time.
[0162]
The data input unit 110 is a unit for the operator to input various data to be described later and an instruction to the central monitoring device 100 to be registered in the monitoring information storage unit 105, and is an input device such as a keyboard and a pointing device. . The tag identification display reading unit 112 is a unit that reads the tag identification display attached to the wireless tag 10.
[0163]
The abnormality determination processing unit 120 performs an entry prohibition process to be described later based on data stored in the monitoring information storage unit 105, the flow line pattern storage unit 160, and the image storage unit 150 at predetermined time intervals or in response to an instruction from the operator. Then, the tag suspicious individual detection process, the suspicious individual detection process, and the route instruction process are executed.
[0164]
The display unit 130 is a unit that displays a specific image stored in the image storage unit 150 according to an instruction of the abnormality determination processing unit 120, or notifies detection of a fraudulent visitor, a tag non-carrier and a suspicious person, For example, it is configured by a CRT (Cathode Ray Tube) display device or a liquid crystal display device.
[0165]
The door control unit 131 instructs the lock mechanism 62 specified by the above-described door identification information to perform locking or unlocking control in accordance with the instruction of the abnormality determination processing unit 120. The security instruction unit 132 gives a security instruction to a mobile terminal or the like carried by a security guard. The warning instruction unit 133 transmits a signal indicating a warning operation instruction to one of the wireless tags 10 to the relay processing device 40 according to the instruction of the abnormality determination processing unit 120.
[0166]
The camera control unit 134 controls the operation of the surveillance camera 70 specified by the above-described camera identification information in accordance with an instruction of the abnormality determination processing unit 120 or an instruction of the operator, and stores an image captured by the surveillance camera 70 in an image. It is stored in the unit 150. The route instruction unit 140 transmits a signal indicating a route guidance instruction to one of the wireless tags 10 to the relay processing device 40 according to the instruction of the abnormality determination processing unit 120.
[0167]
The monitoring information storage unit 105 stores a tag identification information table, a reader table, a person table, an attribute table, a tag-person correspondence table, a camera table, and a door table created by inputting data by the data input unit 110. are doing.
[0168]
As shown in FIG. 29, the tag identification information table is a table that associates the tag identification information given to the wireless tag 10 with the tag identification information held by the identification information storage unit 11 of the wireless tag 10. When the tag identification display of the wireless tag 10 is read by the tag identification display reading unit 112, the tag identification information table is referred to to specify the tag identification information associated with the tag identification display.
[0169]
As shown in FIG. 30, the reader table is a table in which a location code, a name, and a zone of a place where the tag reader 20 specified by the reader identification information is arranged are associated with each of the above-described reader identification information. is there.
[0170]
As shown in FIG. 31, the person table stores personal information such as the name, age, destination, and attribute information of the person identified by the person identification information for identifying the person carrying the wireless tag 10. Is a table associated with.
[0171]
As shown in FIG. 32, the attribute table is a table in which attribute information included in the person table is associated with each location code included in the reader table. Specifically, whether a single location code is allowed to enter the monitored area specified by the location code depends on the visitor, facility staff, facility senior staff, security manager, part-time job staff, visitor, etc. It is set for each of a plurality of attributes distinguished by. For example, in FIG. 32, attribute 2 is a place code ZID. ₁ And ZID ₂ Is allowed to enter the monitoring area specified by ₃ Access to the surveillance area specified in is prohibited.
[0172]
In addition, it is preferable that the attribute table is provided with a temporary visitor attribute in which the wireless tag 10 is frequently distributed and collected. For example, in this temporary visitor attribute, the set values corresponding to all the place codes are set in advance in the restricted area, and the destination (destination) of the visitor entered when creating the people table , The setting value corresponding to the location code may be automatically changed to the access permitted area. Specifically, the central monitoring device 100 is provided with an attribute setting unit (not shown), and the attribute setting unit avoids, from the route from the entrance to the above-mentioned destination, a monitoring area where entrance of customers is originally prohibited. An optimum route is determined, and an attribute table is created so that the monitoring area on the route is set as an access permitted area.
[0173]
As shown in FIG. 33, the tag-person table is a table in which the above-described tag identification information is associated with the person attribute information included in the person table. In particular, the tag-person correspondence table is useful for acquiring personal information of a person carrying the wireless tag 10 specified by the tag identification information from the tag identification information by referring to the above-described person table. .
[0174]
As shown in FIG. 34, the camera table is a table in which the above-described camera identification information is associated with a location code included in the reader table.
[0175]
As shown in FIG. 35, the door table is a table in which the above-mentioned door identification information is associated with a place code included in the reader table.
[0176]
As described above, the tag identification information table, the reader table, the person table, the attribute table, the tag-person correspondence table, the camera table, and the door table have a normalized relationship with each other, and constitute a relational database. Thereby, for example, even when the tag reader 20 arranged in a specific monitoring area breaks down and needs to be replaced with the tag reader 20 specified by the new reader identification information, the attribute table, the camera table, and the door table are not changed. Since it is associated with a place code that is highly likely to be unchanged, it is only necessary to change the tag identification information of the failed tag reader 20 in the reader table. That is, the registration change work can be minimized, and the labor of the administrator can be reduced.
[0177]
The monitoring information storage unit 105 stores a flow line table managed by the data management unit 101. As shown in FIG. 26, the flow line table indicates, for each tag identification information, the time when the user entered the monitoring area specified by the location code (the entry time t). ₀ ) And the time of leaving (departure time t ₁ ) Is a table in which stay times calculated between the times are associated with each other.
[0178]
In FIG. 25, the image storage unit 150 stores the video data of the monitoring camera 70 obtained via the camera control unit 134 and the image data indicating the shape of the venue and the layout of the tag reader 20 and the like as shown in FIG. And are stored. It is desirable that the storage format of the video data and the image data be compressed and encoded. In particular, it is preferable that the video data be stored by a method of encoding for each object such as so-called MPEG-4. This makes it easy to extract a background image or an object such as a person from the video data, and reduces the load on the abnormality determination processing unit 120 for extracting a person in the image, detecting a person's movement, and the like. Further, such compression encoding may be performed by each monitoring camera 70.
[0179]
In FIG. 25, the flow line pattern storage unit 160 stores a flow line pattern expressing a suspicious behavior by a numerical value or a character string according to a predetermined rule. This flow line pattern is referred to in a suspicious person detection process described later.
[0180]
Note that the central monitoring device 100 is, for example, a personal computer or a workstation including a processor (MPU), an auxiliary storage device such as a memory, a hard disk drive (HDD), an input device such as a keyboard, a display device, and an output device such as a printer. It can be configured as an information processing device.
[0181]
Further, the central monitoring device 100 may have the same function as the tag reader 20, and may read the tag identification information of the wireless tag 10 by itself. Hereinafter, the entry prohibition process, the tag non-carrier person detection process, the suspicious person detection process, and the route instruction process will be described in order.
[0182]
・ Restricted entry processing
First, the off-limits processing will be described. FIG. 37 is a flowchart showing the entry prohibition processing. Here, it is assumed that the tag reader 20 is connected to the relay processing device 40 via a shared wiring cable.
[0183]
As described above, the wireless tag 10 carried by the entrant periodically transmits the tag identification information of the wireless tag 10. Therefore, when the visitor enters the monitoring area, the tag reader 20 belonging to the monitoring area acquires the tag identification information of the wireless tag 10 (step S11). In other words, the tag reader 20 detects that the wireless tag 10 exists in the monitoring area where the tag reader 20 is located. Upon acquiring the tag identification information, the tag reader 20 transmits the reader identification information assigned to itself to the relay processing device 40 together with the acquired tag identification information (step S21). Upon receiving the set of the tag identification information and the reader identification information, the relay processing device 40 transmits the set to the data management unit 101 of the central monitoring device 100 (step S31).
[0184]
When receiving the set of the tag identification information and the reader identification information, the data management unit 101 of the central monitoring device 100 executes a flow line table registration process (step S41). Specifically, the data management unit 101 first refers to the monitoring information storage unit 105 to check whether or not the flow line table of the received tag identification information has already been created. , A flow line table of the tag identification information is newly created. Then, the data management unit 101 specifies the location code based on the received reader identification information and the reader table described above, and registers the specified location code in the location code column of the flow line table (registration 1). If no value is registered in the entry time column in the line specified by the location code, the time at which the information was received is registered in the entry time column (registration 2). On the other hand, if a value is registered in the entry time column in the line specified by the location code, the time at which the information was received is registered in the exit time column (registration 3). The data management unit 101 repeats the above registration 3 until the location code changes. When the location code changes, the above-described registration 1 is performed for a new location code, the stay time is calculated from the entry time and the exit time of the immediately preceding row, and the calculation result is stored in the same row. Register in the time column. Thus, the flow line table is updated each time the data management unit 101 receives the tag identification information and the reader identification information from the relay processing device 40. Note that this registration example assumes that the tag reader 20 is given a priority for detecting the wireless tag 10.
[0185]
The movement history of each wireless tag 10 can be obtained by the flow line table registration processing. In particular, as shown in FIG. 12, since the primary key of the flow line table of each tag identification information is the location code, even if the reader identification number is changed due to the failure of the tag reader 20, the past movement is not performed. The history can be used continuously.
[0186]
The abnormality determination processing unit 120 of the central monitoring apparatus 100 executes the entry prohibition processing when the content of the flow line table is changed as described above or periodically. Specifically, the abnormality determination processing unit 120 specifies the person identification information from the tag identification information by referring to the above-described tag-person correspondence table, and refers to the above-described person table, thereby determining the person identification information from the person identification information. The attribute is specified, and the entry permission information set for the specified attribute is referred to from the attribute table described above (step S42). Further, the abnormality determination processing unit 120 obtains a setting value corresponding to the location code specified in the setting 1 from the entry permission information. When this set value indicates “no entry”, the abnormality determination processing unit 120 is permitted to enter the monitoring area specified by the location code by the person carrying the wireless tag 10 indicating the tag identification information. It is determined that it has not been performed (step S43).
[0187]
When determining that the entry is not permitted, the abnormality determination processing unit 120 identifies the tag identification information and the reader identification information from the flow line table being referred to and the above-described reader table, and identifies the identified tag identification information and the reader identification. A warning instruction signal including a set of information and a warning operation instruction is transmitted to the warning instruction unit 133.
[0188]
Upon receiving the warning instruction signal, the warning instruction unit 133 transmits the warning instruction signal to the relay processing device 40 (Step S44). Upon receiving the warning instruction signal, the relay processing device 40 extracts the reader identification information included in the warning instruction signal, and transmits the tag identification information and the warning operation instruction to the tag reader 20 specified by the extracted reader identification information. A warning instruction signal including the warning instruction signal is transmitted (step S32).
[0189]
Upon receiving the warning instruction signal, the tag reader 20 extracts the tag identification information included in the warning instruction signal, and transmits the warning instruction signal including the warning operation instruction to the wireless tag 10 specified by the extracted tag identification information. The call is transmitted (step S22).
[0190]
Upon receiving the warning instruction signal, the wireless tag 10 performs a light emitting operation by the light emitting unit 16, a sound output by the speaker 17 or a vibration operation by the vibration unit 18 according to the warning operation instruction indicated by the warning instruction signal (step S12).
[0191]
Thus, a visitor carrying the wireless tag 10 can know that he / she has entered the restricted area. In the warning operation of step S12, if the sound output from the speaker 17 is increased stepwise, even if the entrant intentionally enters the restricted area, the entrant may take suspicious behavior. Can be notified to the surroundings.
[0192]
In addition, the abnormality determination processing unit 120 transmits a warning instruction signal to the relay processing device 40, and refers to the above-described reader table and door table, so that an intruder enters the monitoring area or a nearby area. It is confirmed whether or not the lock mechanism 62 exists in the monitoring area (Step S45). If the lock mechanism 62 exists in the monitoring area, the abnormality determination processing unit 120 checks whether or not the lock mechanism 62 is located in the off-limits area by further referring to the attribute table. If it is located in the restricted area, the abnormality determination processing unit 120 transmits a door control signal including the door identification information for specifying the lock mechanism 62 and a lock instruction to the door control unit 131 (step S46). Upon receiving the lock instruction, the lock mechanism locks the corresponding door. Thus, it is possible to prevent a entrant from entering the exclusion area surrounded by the wall 50. Note that the abnormality determination processing unit 120 refers to the flow line table, and determines, via the door control unit 131, the lock mechanism 62 that has issued the lock instruction when it determines that the entrant has left the restricted area. To send an unlock instruction. This unlocks the locked door and returns it to its original state.
[0193]
Further, the abnormality determination processing unit 120 transmits the warning instruction signal to the relay processing device 40 and specifies the camera identification information by referring to the above-described reader table and camera table (step S47). Then, a camera control signal including the specified camera identification information and the camera control instruction is transmitted to the camera control unit 134 (step S48).
[0194]
Here, the camera control instruction is a shooting start instruction or a zoom operation by the monitoring camera 70 specified by the camera identification information. At this time, the abnormality determination processing unit 120 may cause the display unit 130 to display the video being captured by the monitoring camera 70 in real time. Further, the abnormality determination processing unit 120 refers to the past wireless tag history information recorded in the flow line table and the past surveillance camera video stored in the image storage unit 150, so that the display unit 130 is suspicious. A video of the past behavior of the person may be displayed. Furthermore, by referring to the flow line table and the camera table, the abnormality determination processing unit 120 switches the camera that captures the monitoring area in which the corresponding wireless tag is detected to the main camera, and tracks the suspicious person to capture the suspicious person. You can also.
[0195]
In addition, the abnormality determination processing unit 120 causes the display unit 130 to display that an intruder who has entered the restricted area is detected (step S49). At this time, by referring to each of the above-described tables, information for specifying the monitored area, personal information for specifying a visitor, tag identification information, and the like may be displayed on the display unit 130.
[0196]
Further, the abnormality determination processing unit 120 can also transmit a security instruction signal including the information specifying the monitored area, the personal information, the tag identification information, and the like to the security instruction unit 132. For example, the abnormality determination processing unit 120 transmits the security instruction signal to the security instruction unit 132 only when the visitor stays in the restricted area for a predetermined time.
[0197]
The above warning process may be executed in combination with a plurality of processes, or one of them may be selected according to the situation.
[0198]
In this monitoring system, since the attributes of the individual entrants are managed by the central monitoring device 100, it is easy to change the attributes of the entrants according to the situation (for example, the number of warnings of the entrants). .
[0199]
In addition, in this monitoring system, a warning process other than the locking of the door 60 can be selected, so that entry can be restricted without enclosing the off-limits area with the wall 50, the door 60, or the like. For example, when a warning sound, vibration, or the like is generated in the wireless tag 10 when approaching a restricted area, or when security is instructed by the security instruction unit 132, the wall 50, the door 60, and the like may not be provided. Restrictions on access can be made.
[0200]
In the above description, the necessity of the warning is determined using the current position of the wireless tag 10, but the history of the warning for each wireless tag 10 may be registered in the flow line table. This makes it easy to identify a visitor who has many warnings (ie, a suspicious visitor).
[0201]
Particularly in this case, the abnormality determination processing unit 120 displays the image of the monitoring area as shown in FIG. 3 by referring to the image storage unit 150 on the display unit 130, and refers to each of the tables. Thus, the positions of all wireless tags 10 are displayed in the image. Then, the wireless tag 10 that has performed the warning process a predetermined number of times (for example, three times) is displayed in a special display mode (for example, changing the color or blinking). As a result, the existence and position of the suspicious entrant can be easily recognized. Further, when there is a wireless tag 10 for which the warning process has been performed a predetermined number of times or more, the abnormality determination processing unit 120 issues a camera control instruction to preferentially shoot a monitoring area where the wireless tag 10 exists, to the camera control unit 134. May be sent.
[0202]
Further, the abnormality determination processing unit 120 may execute the above-described warning process based on the behavior pattern registered in the flow line table.
[0203]
The entry permission information set in the attribute table described above indicates either entry permission or entry prohibition, but may include other setting values such as “not set”.
[0204]
Further, as shown in FIG. 28, in the area where the tag detection range of each tag reader 20 partially overlaps, which of the tag readers 20 is valid for detection is determined by the abnormality determination processing unit 120 in the attribute table described above. May be determined on the basis of the entry permission information set in. For example, it is determined that tag detection by the tag reader 20 in the monitoring area set to “no entry” is valid. That is, which of the tag readers 20 is effective for detection changes according to the attribute of the entrant.
[0205]
・ Tag non-carrier detection processing
Next, the tag non-carrying person detection processing will be described. FIG. 38 is a flowchart showing the tag non-carrier detection process. The tag non-carrier detection process is executed by the central monitoring device 100.
[0206]
First, the operator uses the data input unit 110 to specify a monitoring area in which a tag non-carrier is to be detected, or the abnormality determination processing unit 120 sequentially specifies monitoring areas sequentially by referring to the reader table described above. The monitoring area to be subjected to the tag non-carrier detection process is specified (step S101).
[0207]
Then, the abnormality determination processing unit 120 refers to the above-mentioned flow line table, includes a location code indicating the specified monitoring area, and has a line where the entry time is registered but the exit time is not registered. A flow line table is extracted, and tag identification information corresponding to the extracted flow line table is specified. In addition, the number of the specified tag identification information, that is, the number (TN) of the wireless tags 10 existing in the monitoring area targeted for the tag non-carrier detection processing is calculated (step S102).
[0208]
Further, the abnormality determination processing unit 120 specifies the camera identification information corresponding to the location code indicating the monitoring area by referring to the camera table. Then, the latest video data specified by the camera identification information is acquired by referring to the image storage unit 150 (step S103). Then, the abnormality determination processing unit 120 detects the number (CN) of persons projected in the acquired video data (Step S104).
[0209]
Subsequently, the abnormality determination processing unit 120 determines whether or not the number (TN) of the wireless tags 10 in the monitored area matches the number (CN) of the persons in the video in the monitored area (step S105). . If they do not match, specifically, if CN> TN, the abnormality determination processing unit 120 determines that at least one of the persons shown in the video is a tag non-carrying person, and displays this to the display unit. 130 is displayed (step S106). On the other hand, if they match, the abnormality determination processing unit 120 causes the display unit 130 to display no processing or the number of CNs and TNs.
[0210]
In addition, in step S104 described above, when there is a person who does not carry the wireless tag 10 in step S104, the abnormality determination processing unit 120 refers to the flow line table or the like to carry the portable You may identify those who do not. More specifically, as shown in FIG. 39, a human image in the video 91 is detected and characterized by feature amounts such as height, color, clothes, etc., and a unique identification number is assigned to the characterized human image and a predetermined identification number is assigned. In the table 93 of FIG. Further, the abnormality determination processing unit 120 specifies a person who is recognized by the same combination of feature amounts between different videos by the above-mentioned identification number, and, as shown in FIG. A person recognition table is created by associating the indicated location code with the recognition time. Then, the abnormality determination processing unit 120 extracts the movement history of the wireless tag 10 represented by the same time sequence as the person recognition table by referring to the above-mentioned flow line table. This movement history is, specifically, a tag movement history table in which each tag identification information is associated with a location code at each time. Then, the abnormality determination processing unit 120 compares the movement history table with the person recognition table, excludes the record of the identification number having the same transition of the place code from the person recognition table, and uses the remaining recognition number as a reference. The specified person image is specified as the tag non-carrier.
[0211]
When the person who does not carry the wireless tag 10 is identified in this way, as shown in FIG. 41, the abnormality determination processing unit 120, together with the image 130c, the image area 130h corresponding to the tag non-carrier in the image Is displayed on the display unit 130 in an emphasized manner.
Further, as shown in FIG. 17, the abnormality determination processing unit 120 determines the number of wireless tags 10 (TN) calculated in step S102 and the number of people in the video data (CN) detected in step S104. The display unit 130 may display the tag identification information of the detected wireless tag 10, a message indicating that the tag non-carrier is present, and the like.
[0212]
・ Suspicious person detection processing
Next, the suspicious individual detection process will be described. FIG. 42 is a flowchart showing the suspicious individual detection process. The suspicious individual detection process is executed by the central monitoring device 100.
[0213]
First, the operator uses the data input unit 110 to input a place where a suspicious individual is to be detected (step S201). For example, the input of the detection location may be realized by designating a plurality of monitoring areas, for example. Subsequently, the operator uses the data input unit 110 to input a time range in which a suspicious individual is to be detected (step S202). Further, the operator uses the data input unit 110 to input a condition for detecting a suspicious individual (step S203). This condition is, for example, that 100 or more wireless tags have been detected at the detection location input in step S201, or that a visitor having specific personal information has been specified.
[0214]
Then, the abnormality determination processing unit 120 determines whether or not the above-described detection condition is satisfied by referring to the above-described flow line table (step S204). , Data that satisfies steps S201 to S203 is specified, and a flow line comparison character string is generated using the specified data (step S205). The following is a description of the flow line comparison character string.
[0215]
FIG. 43 is a diagram illustrating an example of a flow line comparison character string. The flow line comparison character string is composed of a character string representing a place code and a stay time for each piece of tag identification information corresponding to the specified data. For example, one character indicates that the wireless tag 10 specified by the tag identification information has stayed at the place code assigned to the character for one minute. In FIG. 43, for easy understanding, the location code ZID ₁ , ZID ₂ , ZID ₃ Are represented by A, B, and C. Therefore, FIG. ₁ Stay for 30 minutes in the monitoring area specified by, then place code ZID ₂ Stay for 10 minutes in the monitoring area specified by, then place code ZID ₃ Stayed in the monitoring area specified in the above for 5 minutes and finally place code ZID ₁ Represents a flow line comparison character string of the wireless tag 10 that has stayed in the monitoring area specified for 1 minute.
[0216]
The abnormality determination processing unit 120 compares the flow line comparison character string with each flow line pattern stored in the flow line pattern storage unit 160 (Step S206). The following is an example of a flow line pattern.
[0219]
"Example 1 of traffic line pattern": The same wireless tag 10 exists in the same monitoring area for a predetermined time or more.
This is a pattern for detecting a resident who has stayed at one location for an unnecessarily long time, or for detecting an abandoned wireless tag 10.
"Example 2 of flow line pattern": There is a wireless tag 10 that has traveled back and forth a predetermined number of times between two monitoring areas within a predetermined time.
This is a pattern for detecting a roaming entrant.
"Example 3 of flow line pattern": There are wireless tags 10 moving between a predetermined number or more of monitoring areas within a predetermined time.
This is a pattern for detecting an occupant moving faster than necessary between monitored areas.
[0218]
In order to express the contents as in the above example, the flow line pattern may include a location code and a code “*” representing an arbitrary character or character string. For example, when the predetermined time is 1 hour in “flow line pattern example 1”, the flow line pattern (PAT1) is
PAT1 = AAA ... A (A is continuous for 60 pieces)
Is represented by Here, A is the location code of the monitoring area.
[0219]
When the predetermined time is 30 minutes and the predetermined number of times is 3 in the “flow line pattern example 2”, the flow line pattern (PAT2) is
PAT2 = A * B * A * B * A * B and LEN (PAT2) = 30
Is represented by Here, A and B are location codes of the monitoring area. * Represents zero or more arbitrary character strings. In the above PAT2, the condition of 30 minutes imposes a restriction that the length of the PAT2 is 30. Therefore, the number of character strings LEN (PAT2) = 30.
[0220]
The abnormality determination processing unit 120 verifies whether or not such a flow line pattern is included in a plurality of target flow line comparison character strings. For example, a flow line comparison character string is
FFFFAACCCCBDAEBFFAEEEEBCCCAEEEEEEE
In this case, this flow line comparison character string does not include the above-described PAT1, but includes the above-described PAT2. Therefore, it is determined that the entrant of the behavior pattern indicated by the flow line comparison character string makes at least three round trips on A and B within 30 minutes.
In addition, in addition to the above-described examples 1 to 3, the flow line pattern storage unit 160 stores a pattern for detecting whether or not there is a wireless tag 10 that is out of the monitored area or a wireless tag 10 that has failed or is intentionally destroyed. It may be stored as a flow line pattern.
[0221]
In step S206, when the abnormality determination processing unit 120 detects that the flow line comparison character string includes a flow line pattern, in other words, a part of the flow line comparison character string matches the flow line pattern. In this case (step S207: YES), a movement history of the wireless tag 10 corresponding to the flow line comparison character string, that is, a flow line is generated by referring to the flow line table, and the generated flow line is displayed on the display unit 130. (Step S208). Further, the abnormality determination processing unit 120 specifies the tag identification information of the wireless tag 10, the monitoring area where the wireless tag 10 is currently located, the personal information, and the like by referring to each of the tables (step S209), and checks the information for suspicion. The result is displayed on the display unit 130 as a result of the person detection (step S210).
[0222]
In addition, the abnormality determination processing unit 120 may verify not only the flow line comparison character string and the flow line pattern but also the correlation between the two flow line comparison character strings. Specifically, when the similarity of a character string is calculated using a similarity comparison method used in genomic analysis or the like between two flow line comparison character strings and the similarity is equal to or greater than a predetermined degree. Then, it is possible to determine that the entrant carrying the wireless tag 10 corresponding to the flow line comparison character string is a suspicious individual.
[0223]
Further, instead of simply determining a suspicious person only by a flow line, a determination condition according to personal information may be defined as a flow line pattern. For example, the abnormality determination processing unit 120 may include, in the determination condition of the suspicious individual, whether or not the individual is a cautionary person (for example, a person with a criminal record) or a security guard by referring to the personal information in the above-mentioned person table. it can.
[0224]
・ Route instruction processing
Next, the route instruction processing will be described. The route instruction processing is executed by the route instruction unit 140 of the central monitoring device 100. In order to receive the route instruction by the route instruction unit 140, the wireless tag 10 transmits the wireless transmission and reception including the identification information holding unit 11, the transmission unit 12, the transmission / reception switching unit 13, and the reception unit 15, as shown in FIG. The warning operation unit 9 shown in FIG. 20 is integrally formed as a PC card 170 having a unit 171 and an antenna 14, and a display of a portable information terminal 180 such as a PDA (personal digital assistant) connected to the PC card or the like. Section, a speaker, a vibrating section, and the like.
[0225]
The route instructing unit 140 extracts the image data of the monitoring area from the image storage unit 150, and extracts the position information and the off-limits area information of the portable information terminal 180 functioning as the wireless tag 10 from the monitoring information storage unit 105. The image data and the position information are transmitted to the portable information terminal 180 via the relay processing device 40.
[0226]
The portable information terminal 180 receives the image data and the position information via the antenna 14 and the wireless transmission / reception unit 171. As a result, the portable information terminal 180 displays an image indicating the map 161 of the monitoring area, the route 162, the off-limits area 163, the current position 164, the direction 165, and the like on the display unit 169 as shown in FIG.
[0227]
In order to display the direction, the portable information terminal 180 is provided with a means for detecting a direction such as a gyroscope or a geomagnetic azimuth sensor, and the direction of the direction 165 indicating the direction according to the detection output of the direction detection function is provided. It is necessary to provide a function of generating image data.
[0228]
Further, the portable information terminal 180 displays the display of the direction 165 in blue when heading to the destination (outbound) or exit (return), yellow when heading to another destination, and red when heading to a restricted area. Is displayed, the visitor can easily recognize the route. In addition, the route guidance in such a form can be displayed by using a light emitting unit including an LED or the like, instead of the PDA.
[0229]
(Embodiment 4)
Next, a monitoring system and a monitoring method according to the fourth embodiment will be described. The monitoring system and the monitoring method according to the fourth embodiment are modifications of the above-described third embodiment.

In FIG. 45, the same reference numerals are given to parts common to FIG. 45 differs from FIG. 25 in that a relay processing device 240 is provided instead of the relay processing device 40, and a plurality of human detection sensors 30 are connected to the relay processing device 240. The human detection sensor 30 is provided for each monitoring area similarly to the tag reader 20, and detects the detection by detecting, for example, infrared rays, sound, weight, or radio waves emitted from a device such as a mobile phone carried by an entrant in the monitoring area. It detects whether there is a person in the monitored area. This embodiment is characterized in that a tag non-carrier is detected using the detection output of the human detection sensor 30.
[0231]
The relay processing device 240 functions in the same manner as the relay processing device 40 shown in FIG. 1, collects the detection output of the human detection sensor 30, and, at a predetermined time interval, transmits the collected information to the central monitoring device 100. This is transmitted to the determination processing unit 120. The information transmitted by the relay processing device 240 to the central monitoring device 100 includes, for example, as shown in FIG. 46, the reader identification information of the tag reader 20 and the tag identifications of all the wireless tags 10 detected by the tag reader 20 installed in the monitoring area. 9 is a table showing a correspondence between information and information (sensor output, for example, 0: none, 1: present) indicating the detection output of the human detection sensor 30 installed in the monitoring area.
[0232]
FIG. 47 is a flowchart showing the tag non-carrier detection process according to this embodiment. Upon receiving the set of the reader identification information, the tag identification information, and the sensor output shown in FIG. 46 from the relay processing device 240 (step S301), the abnormality determination processing unit 120 checks whether the sensor output is 1 or not. (Step S302). When the sensor output is 1, that is, when there is an occupant in the monitored area, the abnormality determination processing unit 120 calculates the number of the tag identification information to determine the number of the radio waves detected in the monitored area. The number (TN) of the tags 10 is calculated (step S303). When the number of the wireless tags 10 is 0 (step S304: YES), the abnormality determination processing unit 120 determines that there is a person who does not carry the wireless tag in the monitored area, and that fact is displayed on the display unit. 130 is displayed (step S305). On the other hand, when the sensor output is not 1 in step S302 and when the number of wireless tags 10 is not 0 in step S304 (step S304: NO), the abnormality determination processing unit 120 executes steps S42 to S49 in FIG. Accordingly, the relay processing device 240, the tag reader 20, and the wireless tag 10 execute steps S32, S22, and S12, respectively. That is, the entry prohibition process as described above is thereby executed.
[0233]
As described above, in the monitoring system and the monitoring method according to the third and fourth embodiments, the abnormality determination processing unit 120 determines whether or not the entry permission information of the visitor held in the attribute table of the monitoring information storage unit 105 includes: It is possible to restrict the entry of the entrant according to the current position and the history of the entrant held in the flow line table.
[0234]
In addition, the monitoring system and the monitoring method according to the third and fourth embodiments can be used even when a visitor takes a suspicious action such as leaving or destroying the wireless tag 10 and not carrying the wireless tag. , It can be found or the place where the action was taken can be specified, and the access restriction can be further ensured.
[0235]
Further, in the monitoring system and the monitoring method according to the third and fourth embodiments, the abnormality determination processing unit 120 uses the history of the position of each wireless tag 10 held in the flow line table of the monitoring information storage unit 105 to determine the subject. By analyzing the flow line, the attribute of the person to be monitored is determined, and a suspicious person can be found according to the determination result.
[0236]
In the monitoring system and the monitoring method according to the third and fourth embodiments, the path instruction unit 140 converts the data stored in the monitoring information storage unit 105 and the image storage unit 150 into a portable information terminal that functions as the wireless tag 10. Since the data is transmitted to the portable information terminal 180, the portable information terminal 180 can realize the navigation function using the data.
[0237]
The operation procedure of the monitoring system according to the first to fourth embodiments described above, that is, the monitoring method can be executed by a computer program. More specifically, the entry restriction information setting process, the attribute correspondence registration process, and the position monitoring process described in the first embodiment, the advance information registration process, the operating information setting process, and the non-carrier detection described in the second embodiment Processing, behavior suspicious person detection processing, and display control processing, entry exclusion processing, tag suspicious person detection processing, suspicious person detection processing, and route instruction processing described in Embodiment 3, and tag ineligibility processing described in Embodiment 4 The person detection processing and the like can be executed as a computer program on the monitoring system according to each embodiment.
