Description

  The present invention relates to an approach notification technique using an RFID (Radio Frequency Identification) tag.

  Conventionally, in order to detect an intruder using an RFID tag, an RFID tag is carried by a target person who has the possibility of entering, and it is detected that the target person has entered the reception area of the RFID receiver. Some recognize the approach. For example, in the video system using the wireless tag position information of Non-Patent Document 1, an RFID tag is assigned to a photographing target to be identified, and a camera video in which the target is photographed is selected according to the reception status in the RFID receiver. The video is browsed via the network. In this video system, it is possible to recognize an approach by installing a camera and an RFID receiver in a region where the approach is to be detected.

  Furthermore, the intruder detection device provided in a facility such as a condominium in Patent Document 1 allows a resident's tag to be carried by a condominium resident, and a tag is issued by an operation from the inside by the resident when the visitor is notified of the visit through an intercom. The machine issues a tag and lets the customer carry the tag. When the host computer confirms a resident and a visitor near the automatic door by the recognition device and the RFID receiver, the host computer opens the automatic door. Further, the host computer recognizes whether a person moving inside the apartment is a resident or a visitor by using a recognition device and an RFID receiver installed in a passage inside the apartment. In this case, if the recognition device can confirm the presence of the person but the RFID receiver cannot read the data from the tag ID, the person is regarded as an intruder, and the alarm is sent to a resident or guard. Inform staff.

  Moreover, the parking lot management system using the RFID tag of Patent Document 2 reads the individual identification information from the RFID tag attached to the approaching vehicle when the vehicle enters the parking lot, and the read individual identification information and The validity of the vehicle is determined based on user management information in a user database prepared in advance. When it is determined that the approaching vehicle is not a valid vehicle, unauthorized parking countermeasure processing is executed for the approaching vehicle.

  The photographing system using the RFID tag of Patent Document 3 is an automatic photographing device used in a party venue or the like. The photographing device carries an RFID tag on the photographing side and is photographed by a photographing device having an RFID receiver. The image capturing preference and tag ID on the side are registered, and the field angle of the image capturing device and the target detection area by the RFID receiver are matched. When the object to be photographed enters the field of view, the RFID receiver detects it. Then, the pre-registration information of the photographing apparatus is searched using the tag ID as a key, the presence / absence of photographing desire is determined, and photographing is executed when there is photographing desire.

  In addition, the security system using the RFID tag of Patent Document 4 realizes the entrance restriction control to the monitoring area only by the RFID tag and the RFID receiver, thereby eliminating the network connecting the RFID receiver and reducing the cost. It is intended to do. Specifically, the RFID tag is a response determination for determining whether to respond to an inquiry command together with expiration date information indicating an expiration date for releasing the entry restriction of the entry restriction means held by the RFID receiver. Information is stored in the storage device of the RFID tag itself. When the RFID tag is set to respond in the response determination information stored in the storage device, the RFID tag transmits expiration date information when an inquiry command is received. In addition, when the response determination information stored in the storage device is set to respond, when a no response command for setting the response determination information to no response is received, the response determination information is changed to a setting not to respond to the inquiry by the inquiry command. . When the RFID receiver acquires the expiration date information from the RFID tag, the RFID receiver itself generates date information, and determines whether the date of the date information has passed the expiration date of the acquired expiration date information. If it is determined that the date has not expired, the admission restriction by the admission restricting means is canceled, and if it is determined that the date has expired, the RFID tag response determination information is set to no response. Sends no response command to set.

  As described above, the conventional approach detection method mainly detects the entry of an object into a monitoring area or an area to be protected, but the object itself is an object to be protected, and the object is, for example, dangerous. A mechanism for detecting and notifying that an area has been entered is also required. In such an approach detection method, it is necessary to shorten the time from the occurrence of an event of entry to notification. Also, it is necessary to operate according to various conditions such as the attributes of the entering objects and the date and time zone of the entry.

  In the method of Non-Patent Document 1 described above, the monitoring area where the entry is to be detected is made the same as the RFID tag receiving area, and the ID of the RFID tag is received by the receiver so that the user carrying the RFID tag enters the monitoring area. Recognize that In this method, it is not considered to set various conditions such as the attribute and type of the entering object itself, the entry date and time for the entry detection operation and the operation after the detection. There is a problem that the flexibility of setting the conditions is low.

  In the methods of Patent Documents 1 and 2, the entry is detected by means other than the reception of the RFID tag, and the host computer identifies whether the entry is valid. It is possible to set conditions such as the attribute and type of the entering object itself, the entry date and time, etc. However, considering the application to detecting and notifying that an object itself is a target to be protected and that the object has entered a dangerous area, in this method, the object to be protected enters the dangerous area. Therefore, there is a problem that a time lag until the determination is made in the host computer occurs, and the notification is delayed.

  In addition, in the method of Patent Document 3, when the detection of the entry and the operation determination are performed by the RFID receiver, it is necessary to cause the RFID receiver to maintain a condition that matches each target to be protected at the time of the entry determination process. . However, as the number of target RFID tags and the number of RFID receivers increase, it is practically difficult to store the conditions regarding all RFID tags in the RFID receiver. Furthermore, when the condition data is additionally updated, processing is required for all RFID receivers, resulting in enormous costs. In addition, when the host computer holds conditions that match each target to be protected and inquires about the “operation content” and “operation content execution condition” from the RFID receiver at the time of the entry determination process, the inquiry communication is performed at the RFID receiver. There is a problem that processing load and time are required, and processing load and processing time associated with “RFID receiver operation execution condition” and “RFID receiver operation content search” are also required in the host computer.

  Further, in the method of Patent Document 4, since the RFID receiver performs the detection of the entry and the operation determination based on the information stored in the RFID tag, the time between the entry determination and the subsequent operation is long. It can be processed without delay. However, a system that realizes this method is specialized in operation control for admission restriction, and there is a problem that it is difficult to set various conditions according to individual tags.

  Therefore, the present invention has been made to solve such a problem, and the object thereof is to provide high flexibility in setting conditions for the entry detection operation and the post-detection operation, reducing the processing load, and processing. An object of the present invention is to provide an approach detection system and method capable of reducing time.

  In the present invention, an RFID receiver is first installed around an area (monitoring area) where it is desired to detect the entry of a dangerous area or the like. The mobile object to be detected includes the contents (operation contents) that the RFID receiver wants to operate when the mobile object enters the area and the conditions (operations) for determining that the mobile object has entered the area where the entry is to be detected. A RFID tag storing contents execution conditions) and data (determination data) necessary to determine the conditions is carried or attached. When the mobile object approaches and enters the monitoring area, the RFID tag receives radio waves emitted from the RFID receiver. Then, the RFID receiver receives the operation content, the operation content execution condition, and the determination data from the RFID tag, determines the operation content execution condition using the determination data, and operates when the determination result is true. Execute the contents.

  Further, the monitoring area is classified into an area where entry is not permitted (entrance not allowed area) where it is dangerous for the moving body to enter the area, and an area where access is permitted (entrance allowed area) which is not dangerous. In this case, the RFID tag stores an ID (normal action area ID) of an area in which the moving body normally operates as determination data for determining the operation content execution condition. The RFID receiver compares the area ID of the monitoring area where the RFID receiver is installed with the normal action area ID received from the RFID tag, and determines whether the mobile object has entered the unpermitted area. It is determined as an operation content execution condition whether the vehicle has entered.

  As described above, according to the present invention, when the mobile object enters the monitoring area, the RFID receiver flexibly responds to various conditions such as the attribute of the mobile object and the date and time zone of the entry. The operation content, the operation content execution condition, and its determination data can be set so as to execute the operation according to each. Moreover, since the RFID receiver determines the operation content execution condition when the mobile body to be protected enters the monitoring area, the time lag from the entry time to the condition determination and countermeasure can be reduced. Further, the RFID receiver does not need to query the host computer for the operation content, the operation content execution condition, and the determination data, and the host computer determines the operation content execution condition and searches for the operation content execution condition and the operation content. Since there is no need, the processing load can be reduced and the processing time can be reduced as compared with the case where only the ID is stored in the RFID tag.

  On the other hand, since the RFID receiver determines the operation content execution condition when the mobile object to be protected enters the monitoring area, if the mobile object is a human, information related to personal privacy may flow through the network. There is also a merit that the risk of leakage of personal information can be suppressed.

  Further, the RFID tag stores the operation content, the operation content execution condition, and the judgment data, and the RFID receiver does not need to store such information, so that the storage capacity can be reduced in the RFID receiver. There are benefits. For this reason, there is a high possibility that the RFID receiver used for other purposes can be shared, and there is an advantage that the installation cost of the RFID receiver can be reduced.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The purpose of this embodiment is to protect children on school roads. FIG. 1 is a diagram showing a configuration of an approach notification system according to an embodiment of the present invention. The entry notification system includes an RFID tag 1 carried by a child 2, an RFID receiver 3 that transmits and receives information to and from the RFID tag 1, an omnidirectional camera 4 that captures an image of a monitoring area, an RFID receiver 3, and A network 5 that connects the omnidirectional camera 4, the notification destination device 7, and the service server 6, a service server 6 that manages a series of information related to entry detection, and a notification destination device 7 that is notified of information related to entry detection. Yes. The system receives an RFID signal when the child 2 at the time of attending school enters an area (monitoring area) where the RFID receiver 3 monitors the entry of the child 2 and enters, for example, a dangerous area (inaccessible area). The machine 3 reads the information stored in the RFID tag 1 to detect the entry, and the omnidirectional camera 4 takes a picture of the situation of the child 2 entering the dangerous area. An e-mail for notifying that the user has entered the dangerous area is transmitted to the service server 6 and the notification destination device 7 held by the guardian or the school.

  FIG. 2 is an image diagram showing a reception area of the RFID receiver 3 shown in FIG. In FIG. 2, an area surrounded by a dotted line is a reception area of the RFID receiver 3. One or more RFID receivers 3 and an omnidirectional camera 4 are installed in the monitoring area (entrance detection target area) which is the reception area, and one area ID is set for each RFID receiver 3. Specifically, in the entrance detection target area of the “building material storage area”, the RFID receivers 3-1 to 3-1 and omnidirectional cameras 4-1 to 3 having “jik789” set as the area ID, ”Is included in the RFID receivers 3-4 to 7 and the omnidirectional cameras 4-4 to 7 having“ SZ14137 ”as the area ID, The RFID receivers 3-8 to 11 and the omnidirectional cameras 4-8 to 11 in which “SZ14139” is set as the area ID, and “SZ14138” is set as the area ID in the entry detection target area of “in front of the fire station”. RFID receivers 3-12 to 14 and omnidirectional cameras 4-12 to 14 are installed, respectively.

  FIGS. 3A and 3B are flowcharts illustrating the notification service processing when the approach notification system illustrated in FIG. 1 is applied to the approach detection target region illustrated in FIG. First, the service server 6 sets an entry detection target area where the RFID receiver 3 is actually installed by a user operation using a terminal device (not shown), and an area ID for managing the entry detection target area. A management table is created and registered in the memory (step S3101). Table 1 is an area ID management table. This area ID management table includes “area ID” and “area name”, and the “area ID” and “area name” shown in FIG. 2 are registered in the memory.

  In addition, the service server 6 can be operated by a user operation such as “tag ID”, “user name”, “tag holder name (= child's name)”, “notification destination (= relationship with the user from the tag owner's perspective)”. "Notification destination e-mail address" "Tag holder normal action area" "RFID receiver operation content at the time of entry detection" and "RFID receiver operation execution condition" are registered in the memory (steps S3102, 3103). Here, the “tag holder normal action area” is an area selected by the user as an area in which the child normally acts from the areas managed by the area ID management table.

  Based on these pieces of information, the service server 6 creates a user / notification destination management table and a tag holder management table and registers them in the memory. Table 2 is a user / notification destination management table. This user / notification destination management table includes “tag ID”, “notification destination”, “notification destination e-mail address”, and “user name”, and these pieces of information are registered in the memory. Table 3 is a tag holder management table. This tag holder management table is composed of “tag ID” and “owner name”, and these pieces of information are registered in the memory. The management tables shown in Tables 1 to 3 convert the “tag ID” to the “owner name” and write “notification destination” to “notification destination email address” when writing predetermined information to the RFID tag 1. It is used for conversion into (step S3104).

  When the service server 6 inputs an instruction to write to the RFID tag 1 by the user's operation, the service server 6 performs a predetermined data conversion process (step S3104), and the “notification destination” “tag owner normal action area” is sent to the RFID tag 1. ID (normal action area ID) ”“ RFID receiver operation content at the time of entry detection ”and“ RFID receiver operation execution condition ”are written, and the RFID tag 1 is lent to the tag holder (step S3105). Here, in FIG. 3A and FIG. 3B, the “reception area ID” in the RFID receiver operation condition (operation content execution condition) is set in advance to the RFID receiver 3 that receives information from the RFID tag 1. Information that is set and stored. The “RFID receiver operation execution condition” also includes data (determination data) necessary for determining the operation execution condition. The determination data is, for example, an operation time of the RFID receiver 3 and a normal action area ID described later.

  On the other hand, when the child 2 who is the tag holder enters the monitoring area of the RFID receiver 3, the RFID tag 1 receives the radio wave from the RFID receiver 3 that is constantly transmitting the radio wave (step S3201). The RFID tag transmits “notification destination”, “normal action area ID”, “RFID receiver operation content at the time of entry detection”, “RFID receiver operation execution condition” together with “tag ID” to the RFID receiver 3 (step S3202). . The RFID receiver 3 determines the “RFID receiver operation execution condition” received from the RFID tag 1 (steps S3203 and 3204). If the determination result is true, the “RFID receiver operation at the time of entry detection” is performed. carry out. That is, the RFID receiver 3 transmits a camera shooting instruction to the omnidirectional camera 4 and causes the omnidirectional camera 4 to photograph the child 2 who is a tag holder. Then, the RFID receiver 3 transmits “tag ID”, “reception area ID”, “notification destination”, and “shooting date / time” together with the “shooting data” to the service server 6 via the network 5 (step S3205). When the determination result of “RFID receiver operation execution condition” is false, neither shooting nor transmission is performed.

  The service server 6 uses the “tag ID”, which is the transmission destination information received from the RFID receiver 3, in the “notification destination (use from the perspective of the tag holder) in the user / notification destination management table (Table 2) registered in the memory. On the basis of the “relationship with the user” ”(step S3206). Also, referring to the tag holder management table (Table 3), conversion from “tag ID” to “tag holder name (owner name)” is performed, and referring to the area ID management table (Table 1), “ Conversion from “reception area ID (area ID)” to “area name” is performed (step S3207). Then, the service server 6 uses the mail server function to send the “shooting data”, “tag holder name (owner name)”, “shooting place (area name)”, “address” to the “notification destination e-mail address” of the notification destination 7. "Shooting date and time" is transmitted (steps S3208 and 3209).

  Next, the operation of the RFID receiver 3 will be described. FIG. 4 is a block diagram showing functions of the RFID receiver 3 in the approach notification system shown in FIG. The RFID receiver 3 includes a message receiving unit 8, a message interpreting unit 9, a determining unit 10, a photographing unit 12, a storage unit 13, and a message transmitting unit 14, and also includes a clock unit 11. The message receiving unit 8 receives messages such as “tag ID”, “normal behavior area ID”, “RFID receiver operation execution condition”, “RFID receiver operation content at the time of entry detection”, “notification destination” from the RFID tag 1, The message is passed to the message interpretation unit 9.

  The message interpreting unit 9 converts the message received from the message receiving unit 8 into “tag ID”, “normal action area ID”, “RFID receiver operation execution condition”, “RFID receiver operation content at entry detection”, “notification destination”, etc. And is passed to the determination unit 10. The determination unit 10 acquires necessary information such as “reception area ID” from the storage unit 13, acquires time information from the clock unit 11, and receives the information and the “normal action region ID” received from the message interpretation unit 9. Based on the information such as “RFID receiver operation execution condition”. When the determination result is true (for example, when the “reception area ID” and the “normal action area ID” are different, that is, when the area indicated by the “reception area ID” is an entry non-permitted area, and RFID reception If the time is when the machine 3 is operable), the “tag ID” and “reception area ID” are passed to the imaging unit 12. If the determination result is false, neither shooting nor transmission described later is performed.

  Upon receiving the “tag ID” and “reception area ID” from the determination unit 10, the imaging unit 12 performs imaging and displays “imaging data”, “tag ID”, “reception area ID”, “imaging date”, and “notification destination” message. The data is passed to the transmission unit 14. The message transmission unit 14 transmits the “tag ID”, “reception area ID”, “imaging date / time”, “imaging data”, and “notification destination” received from the imaging unit 12 to the service server 6. In this case, the message transmission unit 14 acquires the address of the service server 6 from the storage unit 13. The storage unit 13 stores information related to basic operations (transmission / reception, imaging, etc.) of the RFID receiver 3 such as “reception area ID” and “address of the service server 6”.

  FIG. 5 is a flowchart showing processing of the RFID receiver 3 shown in FIG. Hereinafter, the process of the RFID receiver 3 will be described by taking as an example a case where the normal action area extends over a plurality of areas. First, the RFID receiver 3 disassembles the message received from the RFID tag 1 into “tag ID”, “normal action area ID”, “RFID receiver operation execution condition”, “RFID receiver operation content”, “notification destination ( In step S5001, the “RFID receiver operation execution condition” is interpreted (step S5002).

  Further, the RFID receiver 3 acquires the current time from the receiver built-in clock unit 11 (step S5003), and determines whether or not the time is within the range of the operation execution time in the “RFID receiver operation execution condition”. Judgment is made (step S5004), and if it is out of range, the judgment process is terminated without performing the process described later (step S5005). If the acquired time is within the range of the operation execution time zone, the “reception area ID” is acquired from the storage unit 13 for use in the determination of the “RFID receiver operation execution condition” (step S5006).

  Then, the RFID receiver 3 determines that “reception area ID ≠ normal action area ID” in the “RFID receiver operation execution condition” (step S5007). If the determination result is false, that is, if “reception area ID = normal action area ID”, the determination process is terminated without performing the process described later (step S5008). If the determination result is true, it is checked whether there is another “normal action region ID” to be compared (step S5009). In this way, the determination of “RFID receiver operation execution condition” is repeated until there is no “normal action region ID” to be compared.

  Then, when there is no “normal action area ID” to be compared, that is, when all the conditions are true, the RFID receiver 3 causes the omnidirectional camera 4 to perform imaging (step S5010). Data, “shooting date / time”, “tag ID”, “reception area ID”, and “notification destination” are transmitted to the service server 6 (step S5011).

  Table 4 is an example of the pre-stored information in the tag / RFID receiver reception table. This pre-tag pre-stored information / RFID receiver reception table is composed of items of “tag ID”, “transmission destination”, “normal action area ID”, “RFID receiver operation execution condition”, and “RFID receiver operation content” and their contents. Has been. As shown in Table 4, in step 3105 in FIG. 3A, the service server 6 sets and writes a plurality of “RFID receiver operation execution conditions” and “RFID receiver operation contents” for the RFID tag 1. It may be. In this case, in step 3204 in FIG. 3-2 and steps 5002 and 5010 in FIG. 5, the RFID receiver 3 determines the operation execution condition in this order and executes the corresponding operation content. A plurality of IDs may be set and written in the “normal action area ID”.

  Table 5 is an example of the pre-stored information in the camera-equipped RFID receiver when the RFID receiver 3 and the omnidirectional camera 4 shown in FIGS. 1 and 2 are integrated. This pre-stored information in the RFID receiver with camera is composed of items of “area ID”, “transfer request destination host”, and “data type” and their contents. As the “transfer request destination host”, the host name or IP address of the service server 6 described above is stored in the memory. In addition to still images, moving images, sounds, and the like are stored as “data type” depending on the device mounted on the RFID receiver 3.

  The RFID receiver 3 is constituted by a computer having a volatile storage medium such as a CPU and a RAM, a non-volatile storage medium such as a ROM, and an interface for communicating with an external device. Also good. The service server 6 includes a CPU, a volatile storage medium such as a RAM, a non-volatile storage medium such as a ROM, an input device such as a keyboard and a pointing device, a monitor device that displays images and data, and an external device. You may make it comprise with the computer provided with the interface for communicating. In this case, the message reception unit 8, the message interpretation unit 9, the determination unit 10, the clock unit 11, the imaging unit 12 and the message transmission unit 14 included in the RFID receiver 3, and each process included in the service server 6 are executed. Each function of the means is realized by causing the CPU to execute a program describing these functions. These programs can also be stored and distributed in a storage medium such as a magnetic disk (floppy disk, hard disk, etc.), optical disk (CD-ROM, DVD, etc.), semiconductor memory, or the like.

  Further, in step 3202 shown in FIG. 3-2, when the tag 2 child 2 enters the monitoring area of the RFID receiver 3, the RFID tag 1 receives “notification destination”, “normal action area ID”, “entrance detection”. RFID receiver operation content ”and“ RFID receiver operation execution condition ”are transmitted to the RFID receiver 3 together with the“ tag ID ”. In this case, the “RFID receiver operation execution condition” includes time information set by the service server 6. On the other hand, the RFID tag 1 is provided with observation information collecting means, and the observation information collecting means collects time, temperature, humidity indicating the state of the RFID tag 1 itself and the surrounding state of the RFID tag 1. The RFID tag 1 may transmit “RFID receiver operation execution condition” including the observation information to the RFID receiver 3 by collecting observation information such as brightness, vibration, and tilt.

  Further, in steps 5003 and 5004 shown in FIG. 5, the determination unit 10 of the RFID receiver 3 obtains the time from the clock unit 11 built in the RFID receiver 3, and uses the time to perform “RFID receiver operation”. "Execution condition" was judged. On the other hand, the RFID receiver 3 includes not only the clock unit 11 but also other observation information collection means, and the observation information collection means shows temperature, humidity, brightness, vibration indicating the RFID receiver 3 itself and the surrounding state. Observation information such as inclination may be collected, and the determination unit 10 may determine “RFID receiver operation execution condition” using the observation information.

  In step 3105 shown in FIG. 3A, the service server 6 sends “notification destination”, “tag holder normal action area ID (normal action area ID)”, “RFID at the time of entry detection” to the RFID tag 1. “Receiver operation content” and “RFID receiver operation execution condition” are written, and the RFID tag 1 stores these pieces of information. In this case, the “RFID receiver operation content at the time of entry detection” includes capturing a still image or video of the child 2 and notifying the image, and the “RFID receiver operation execution condition” includes the still image and video. It is also possible to include data for determining conditions for determining the shooting of any one of the above, data for determining conditions for shooting a still image, and data for determining conditions for shooting a moving image.
