Description

The present invention relates to a movement trajectory grasp support system that collects information for identifying a movement trajectory of a target person (student, kindergarten, sick person, elderly person, etc.) in a server.

Currently, local governments, residents, volunteers, companies, etc. are conducting various activities as a crime countermeasure in order to create a safe and safe town for children. For example, in some areas, guardmen cooperate and hire guardians, and residents and volunteers conduct crime prevention patrols and regular patrols, and provide guidance at street corners. However, while these activities are extremely beneficial, they are far from sufficient to create a safe and secure town for children.

There are the following known technologies that can partially solve this problem, that is, a transmitter that is carried by a student and transmits a unique ID, a reader that recognizes this ID, and this reader. And a server that acquires the student's attendance information based on the recognition information of the student, and automatically delivers the attendance information to the student's parent's terminal via the Internet line based on the information transmitted from this server And an Internet server designed to do this (see Patent Document 1). However, this known technique is not convenient for grasping the movement trajectory of students outside the school and the movement trajectory of persons other than the students.

In addition, the whereabouts of patients with dementia and elderly people with weak judgment may be temporarily lost, and the safety of these persons may be threatened, and many people may be required to search for them.

Embodiments of a subject movement trajectory grasp support system according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a block diagram showing a configuration example of an object person movement trajectory grasp support system according to the present invention, and FIG. 2 is an explanatory diagram showing an operation state of the support system. In the figure, 1 is a radio transmitter, 2 is a base station, 3 is a mobile station, 4 is a relay station, 5 is an Internet line forming a communication network, and 6 is a location information management server.

The wireless transmitter 1 is carried by each of the target persons 7 whose movement trajectories are grasped, and each of them transmits a unique identification information ID, for example, an RFID (Radio Frequency Identification) or an IC tag. It may be a non-contact type recognition device called.

At this time, the RFID includes an IC chip incorporating a communication control circuit and a memory, and an antenna, and can read and write information, write once, write once, or read only. Any of the possible read-only types can be used, and it is preferable that the size of the lead-only type fits into the pocket, and the shape can be any shape such as a card shape or a circle. Further, the RFID may be a passive type to which power is supplied from a reader (which may be a reader / writer) which is a host device of the RFID, or an active type having a power supply. In this embodiment, the cost can be reduced. Therefore, the passive type shall be used.

At least the unique identification information ID is written in this RFID memory, and when it reaches within a distance (for example, about several meters to several tens of meters) within which communication with the base station 2 or the mobile station 3 is possible The identification information ID is transmitted. Alternatively, instead of RFID, a device conforming to the 802.11 standard called a wireless LAN may be used, and a device-specific MAC address may be used as the identification information ID, or a separate identification information ID may be provided.

The base station 2 has a large number of public fixed facilities (such as schools) 8a widely distributed in cities, towns, villages, or school districts, which are the range of action of the target person 7 whose movement trajectory is grasped, and a number of points around the route. It is installed in fixed facilities of many general companies and households. Each base station 2 is provided with a base station radio transmission / reception system 2A.

The base station wireless transmission / reception system 2A includes a reader 12 including a reception antenna 9, a reception circuit unit 10, and a data transmission circuit unit 11, a confirmation computer PC1, and a router 13 connected to the reader 12 and the confirmation computer PC1. The router 13 is connected to the Internet line 5 by wire. At this time, the Internet line 5, the reader 12, and the confirmation computer PC1 may be connected by a wireless LAN. The receiving antenna 9 is preferably installed in a place where radio waves transmitted from the wireless transmitter 1 can be easily received.

An operation example of the base station wireless transmission / reception system 2A will be described. FIG. 3 is a flowchart showing an operation example of the base station radio transmission / reception system 2A. When the power switch of the system 2A is turned ON in step s01, the operation state is entered as shown in step s02, and it is monitored whether or not the wireless transmitter 1 has reached the communicable distance range. As shown in step s03, the person 7 who is grasping the movement locus and carries the radio transmitter 1 approaches the base station radio transmission / reception system 2A, and the radio transmitter 1 and the base station radio transmission / reception system When communication with 2A is possible, the reader 12 emits an electromagnetic wave from the receiving antenna 9 to cause the wireless transmitter 1 to generate a power source and transmit its unique identification information ID, and then as shown in step s04. The reader 12 receives the unique identification information ID transmitted from the wireless transmitter 1, reads it once, and inputs it to the data transmission circuit unit 11. Next, as shown in step s05, the data transmission circuit unit 11 reads the position information of the base station 2 stored in the storage unit in advance, and inputs the position information, the time information at the time of reading, and the reader 12 The movement trajectory basic information including the identified identification information ID is created and output. Next, as shown in step s06, the router 13 sends this movement trajectory basic information to the Internet line 5. Therefore, when the wireless transmitter 1 is continuously present within the range where communication with the base station wireless transmission / reception system 2A is possible, the movement trajectory basic information is created only once in the continuation period, and the Internet line 5 is sent out.

During operation of the base station radio transmission / reception system 2A, it is always determined whether or not the radio transmitter 1 is located within a communicable distance range. The operation is suspended until the wireless transmitter 1 moves away from the communicable distance range. If “No”, the process returns to step s01 and the proximity of the wireless transmitter 1 is monitored. . Alternatively, when the operation suspension state of the base station radio transmission / reception system 2A is continued, the operation suspension state can be canceled at regular intervals to execute the operations from step s01 to step s06, or Instead of this, when the wireless station 1 is moved out of the communicable distance range when the operation suspension state of the base station wireless transmission / reception system 2A is continued, the operations from step s04 to step s06 are performed. It is also possible to return to step s01 after the end of this operation.

Further, the confirmation computer PC1 operates to exchange information with the location information management server 6 via the router 13 at any time. At this time, the router 13 transmits and receives information between the confirmation computer PC1 and the location information management server in parallel with the transmission of the movement trajectory basic information from the data transmission circuit unit 11 to the Internet line 5. It becomes possible.

The mobile station 3 is mounted on a large number of mobile bodies 14a such as vehicles related to the action range of the target person 7 whose movement trajectory is grasped. At this time, the mobile body 14a is an arbitrary vehicle such as a privately owned car by a volunteer, a public vehicle such as a public car, a garbage truck, a delivery vehicle, a taxi, a car sharing vehicle, etc. There is no problem. Each of the mobile stations 3 formed in this manner is equipped with a mobile station radio transmission / reception system 3A.

The mobile station radio transmission / reception system 3A includes a transmitter / receiver circuit unit 15 including a reader and a transmission unit, a position measurement unit 16 that measures the position of the mobile unit 14a, and a mobile unit that is a measurement result of the position measurement unit 16 And a storage unit 17 for storing movement trajectory basic information including position information 14a (identified by latitude and longitude), information received by the receiving unit of the transmission / reception circuit unit 15, and time information at the time of reception. Yes. At this time, as the position measuring means 16, there is one that uses GPS (Global Positioning System) or one that acquires position information by using radio waves emitted from a PHS (Personal Handyphone System) base station. The movement trajectory basic information in the mobile station radio transmission / reception system 3A is created by the calculation unit of the position measuring means 16 and stored in the storage unit 17. The storage unit 17 preferably has a capacity capable of accumulating and storing movement trajectory basic information stored during a period of several hours to several days.

An operation example when the mobile station wireless transmission / reception system 3A receives the unique identification information ID transmitted by the wireless transmission device 1 will be described. FIG. 4 is a flowchart showing the operation of the mobile station radio transmission / reception system 3A at this time. When the power switch is turned on in step s11, the operation state is entered as shown in step s12, and the wireless transmitter 1 is monitored to determine whether it has reached a communicable distance range. In step s13, The person 7 who is grasping the movement locus and who carries the wireless transmitter 1 approaches the mobile station wireless transmission / reception system 3A, and the wireless transmitter 1 and the mobile station wireless transmission / reception system 3A are within the communicable range. When the signal reaches, the reader of the transmission / reception circuit unit 15 emits an electromagnetic wave from the transmission / reception antenna 15a to supply power to the wireless transmitter 1 to transmit its unique identification information ID. The receiver receives the unique identification information ID transmitted from the wireless transmitter 1 and inputs it to the reading position measuring means 16 only once. In connection with the reading, the position measuring unit 16 measures the position of the moving body 14a at this time to calculate the position information of the moving body 14a, and thereafter, the identification information ID received by the transmission / reception circuit unit 15; The movement trajectory basic information including the time information at the time of reception by the transmission / reception circuit unit 15 and the position information of the moving body 14a at the time of reception is created and input to the storage unit 17, and then stored as shown in step s16. The unit 17 stores and saves the movement trajectory basic information. Thereafter, the system 3A operates until the power switch of the system 3A is turned off. Other points are the same as those of the base station radio transmission / reception system 2A.

Next, an operation example when the mobile station wireless transmission / reception system 3A transmits the movement trajectory basic information stored in the storage unit 17 to the relay station 4 will be described. When the mobile station radio transmission / reception system 3A approaches the relay station 4 and can communicate with the relay station 4 under the state where the power switch of the mobile station radio transmission / reception system 3A is ON, the transmission of the transmission / reception circuit unit 15 The unit transmits the movement trajectory basic information stored and stored in the storage unit 17 to the relay station 4. There may be a plurality of relay stations 4 that can communicate with the mobile station 3, but in this case, communication is performed with one relay station 4 specified by a program inputted in advance. The movement trajectory basic information is preferably transmitted while the mobile station 3 is stopped, but is not limited to this, and can be executed while the mobile station 3 is moving. May be separated from the relay station 4 and become unable to communicate with the relay station 4. In this case, a part of the movement trajectory basic information stored in the storage unit 17 is in a state where the transmission is completed and deleted from the storage unit 17, while the movement trajectory basic information excluding this part is directly stored in the storage unit. 17 is left in. Thereafter, when the mobile station 3 moves and approaches another relay station 4 or the same relay station 4 again and can communicate with any one of these relay stations 4, the transmission unit of the transmission / reception circuit unit 15 stores the storage unit. The new movement trajectory basic information stored in and stored in the storage unit 17 after the communication with the previous relay station 4 and the remaining movement trajectory basic information 17 is transmitted to the other relay station 4 or the same relay station 4. . When such communication is performed once or a plurality of times, all the movement trajectory basic information accumulated and stored in the storage unit 17 is transmitted to the relay station 4 and is all deleted from the storage unit 17, and stored in the storage unit 17. Capacity is fully recovered. Such transmission processing of the movement trajectory basic information from the mobile station 3 to the relay station 4 is useful because the capacity of the storage unit 17 is relatively small.

The relay station 4 has a large number of public fixed facilities, a large number of public road surrounding points 18a and a large number of general enterprises widely distributed in the city, town, village, or school district that is the range of action of the target person 7 whose movement trajectory is grasped. 18b and home 18c are provided in a fixed facility. The relay station wireless transmission / reception system 4A is installed in each of the many relay stations 4 provided in this way. This relay station wireless transmission / reception system 4A is installed in a general company 18b, a home 18c, etc. with a broadband line, a personal computer, It is recommended to install between or under the router.

The relay station wireless transmission / reception system 4A includes a reception unit 22 including a reception antenna 19, a reception circuit unit 20, and a data transmission circuit unit 21, a terminal-related unit 24 including a PC control circuit unit 23 and a personal computer PC2, and a filter circuit. The filter circuit unit 25 is connected to the Internet line 5 by wire. At this time, the filter circuit unit 25 and the Internet line 5 or the PC control circuit unit 23 and the personal computer PC2 may be connected by a wireless LAN. The receiving antenna 19 is preferably installed in a place where it is easy to receive radio waves transmitted from the mobile station 3. For example, when a fixed facility such as a general company or a home is a relay station, the receiving antenna 19 should be installed outdoors. Good.

An operation example of the relay station wireless transmission / reception system 4A will be described. When the power switch of the relay station wireless transmission / reception system 4A is turned ON, the relay station wireless transmission system 4 enters an operating state and monitors whether or not the mobile station 3 has reached a communicable distance range. When they are close to the station 4 and can communicate with each other, the receiving circuit unit 10 receives the movement trajectory basic information transmitted from the mobile station 3 and transmits it to the data transmitting circuit unit 21, and then the data transmitting circuit. The movement path basic information whose destination is the location information management server 5 connected to the Internet line 5 is sent to the Internet line 4 via the filter circuit part 25. In this case, the filter circuit unit 25 contributes to preventing the movement trajectory basic information from being transmitted to the terminal related unit 24 side.

The personal computer PC operates to exchange information with the position information management server 6 via the filter circuit unit 25 and the PC control circuit unit 23. At this time, the filter circuit unit 25 contributes to preventing information exchanged between the personal computer PC and the position information management server 6 from being transmitted to the receiving unit 22 side. Further, the PC control circuit unit 23 performs control so that information is accurately exchanged with the Internet line 4. Even when the personal computer PC2 and the data transmission circuit unit 21 exchange information with other devices simultaneously via the Internet line 5, the filter circuit unit 25 hinders their respective operations. There shall be no.

The location information management server 6 includes a data receiving unit 26, a storage unit 27, a calculation unit 28, a data distribution unit 29, an output unit 30, an ID determination unit 31, a display unit 32, and an input unit 33. And is connected to the Internet line 4 by a wired or wireless LAN.

At this time, the data receiving unit 26 is for receiving the movement path basic information transmitted from the base station 2 or the relay station 4 and having the location information management server 6 as the transmission destination. This is for accumulating and storing the received movement trajectory basic information, and the calculation unit 28 classifies the movement trajectory basic information received by the data receiving unit 26 for each identification information ID included therein or arranges them in time series. The data distribution unit 29 contributes to the execution of processing such as storing in the storage unit 27 after processing, and the data distribution unit 29 sends the necessary movement trajectory basic information in response to the data distribution request to the terminal computers PC1 and PC2 that request distribution. The output unit 30 prints the movement trajectory basic information held by the location information management server 6 on the paper surface, and the ID discrimination unit 31 This contributes to determining whether or not the person receiving the service from the information management server 6 is a person who has received registration in advance, and the display unit 32 moves on the liquid crystal screen from the storage unit 27. Information related to the trajectory basic information is displayed, and the input unit 33 is used to input input information, deletion information, correction information, and the like from a keyboard or the like.

Next, a usage example of the above-described subject movement trajectory grasp support system according to the present invention will be described. a: When grasping the movement trajectory of a specific elementary school student when going to and from school The transmitter is carried to all the elementary school students who are the target person 7. The base stations 2 and the relay stations 4 are provided so as to have a uniform distribution within the entire school district of the elementary school or within the entire municipality. At this time, it is preferable to provide a distribution of several tens to several hundreds of meters around the school road of the student 7. In addition, at least one base station 2 is provided in the elementary school, and the receiving antenna 9 is installed near the school gate. The mobile station 3 is also installed in as many vehicles 14a as possible owned by those who live in the school district or municipality related to the elementary school.

Equipment necessary for the base station 2, the mobile station 3, and the relay station 4 and the radio transmitter 1 are preferably managed by the local government or elementary school concerned and lent to those who need it. At this time, a correspondence table between the unique identification information ID of the wireless transmitter 1 and the student 7 who has been lent to the wireless transmitter 1 and their guardians is created. This correspondence table is managed by determining the person in charge at an elementary school, for example, and the correspondence information between each student 7 and the unique identification information ID of the radio transmitter 1 carried by the student 7 is related to that student 7 May know the student 7 and their guardians, but students and guardians can know the correspondence information related to them by inquiring to the elementary school when necessary. There is nothing you have to do.

Under such circumstances, when each student 7 goes to school, the distance within a range (several meters to several tens of meters) that can be communicated with the wireless transmitter 1 carried by each student 7 as the student moves. The existing base station 2 and mobile station 3 change one after another, and receive their unique identification information ID transmitted from the wireless transmitter 1. Each of the received base station 2 and mobile station 3 creates movement trajectory basic information related to the reception, and thereafter, the base station 2 immediately obtains the movement trajectory basic information, and the mobile station 3 When the relay station 4 is within the communicable distance range, the relay station 4 is immediately used. On the other hand, when the relay station 4 is not within the communicable distance range, the relay station 4 is temporarily stored and stored in the storage unit 17. Is transmitted to the location information management server 6 via the Internet line 5 through the relay station.

At this time, the reception of the base station 2 and the mobile station 3 can be performed almost continuously during the period in which the radio transmitter 1 is in a range where communication with the base station 2 and the mobile station 3 is possible. Such an operation by continuous reception is wasteful. In order to deal with this, as already described in detail in the description of the base station 2, the base station 2 and the mobile station 3 receive only at the first time point and / or the last time point of the continuous communicable period with the radio transmitter 1. Correspondingly, the movement trajectory basic information is generated, or the movement trajectory basic information corresponding to the reception is received at regular intervals (for example, several minutes) during the continuous communication possible period. To create.

Individual movement trajectory basic information transmitted from the base station 2 or the mobile station 3 is accumulated and stored in the storage unit 27 of the position information management server 6. At this time, the individual movement trajectory basic information is classified for each unique identification information ID of each radio transmitter 1 and stored and stored in a time-series state in order to speed up subsequent information processing. It is preferable when making it.

The movement trajectory basic information of each student 7 that is stored and stored in the position information management server 6 in this way is returned when the student 7 is not present when the student 7 should be in the elementary school or should return home. It is necessary to grasp the movement trajectory of the student when a situation such as not occurring occurs.

When it becomes necessary to grasp the movement trajectory of a specific student 7, the guardian or the teacher in charge operates the terminal device such as the confirmation computer PC1 or the personal computer PC2 of the base station 2 or the relay station 4 to locate it. By connecting to the information management server 6 and transmitting an information request, the location information management server 6 causes the terminal device to transmit the movement trajectory basic information from the unknown location of the student 7 to the present, The data is output to the display unit or printer of the terminal. The movement trajectory basic information output in this way contributes to specifying the movement trajectory of the student 7 in detail and quickly.

b: When grasping the movement trajectory of a particular kindergarten or nursery school It is sufficient to replace the elementary school in the case of the above a: with a kindergarten or a nursery school. If the target kindergarten or nursery school child lives in the same municipality as the student 7 in the case of a: above, a new environment will be formed if the environment in the case of a: above has already been formed. However, it is sufficient to carry the radio transmitter 1 in accordance with the student 7 in the case of a: to each kindergarten or nursery school child in the environment of a :.

c: When grasping the movement trajectory of a patient such as dementia in a specific hospital, a care recipient of a specific care facility, and an elderly person whose judgment power of a specific family has declined. It is sufficient to replace it with a specific hospital, a specific care facility, or a specific home. If the subject is a specific hospital patient, a care recipient at a specific care facility, or a specific household elderly person living in the same municipality as the student in case a: If the environment has already been formed, a new environment will not be created even if a: the patient of a specific hospital, the care recipient of a specific care facility, or the elderly with reduced judgment of a specific family It is sufficient to carry the radio transmitter 1 according to the student 7 in the case of a: above.

In each of the above cases a :, b :, or c :, it is possible to reduce the number of base stations 2, mobile stations 3, and relay stations 4 or omit the mobile stations 3 and relay stations 4 depending on the scale. Absent.

Next, a modification of the above embodiment will be described. (1) As with the base station radio transmission / reception system 2A, the relay station radio transmission / reception system 4A receives the unique identification information ID transmitted from the radio transmitter 1 directly, thereby almost simultaneously with the reception. It is also possible to create information and send it to the location information management server 6.

(2) Map information is stored in advance in the storage unit 27 of the position information management server 6 or the map information is automatically taken in when the position information management server 6 needs it from the outside through the Internet line 5 or the like. Using the map information and the movement trajectory basic information, a process for drawing the movement trajectory of the person carrying the wireless transmitter 1 on the map is performed, and the result of the process (the map on which the movement trajectory is to be drawn) is displayed. It can also be made to output from the output part 30.

(3) When the mobile station 3 is stopped and the movement trajectory basic information can always be transmitted to the relay station 4, the mobile station 3 may be used as a wide area antenna of the relay station 4.

(4) By providing the base station 2 and the relay station 4 in the station premises and the mobile station 3 in the railway or subway vehicle, the mobile station 3 is transmitted from the radio transmitter 1 around the railway or subway. By receiving the unique identification information ID, the movement trajectory basic information can be created and transmitted to the position information management server 6 almost simultaneously with the reception.

(5) In addition to the identification information ID unique to the wireless transmitter 1, the name, address, mail address, etc. of the person carrying the wireless transmitter 1 are stored, and this information is stored together with the unique identification information on the base The base station 2 and the mobile station 3 receive the personal information and create the basic trajectory of the trajectory by receiving the personal information. The base information of the trajectory and the personal information corresponding to the basic information of the trajectory are generated. Transmitted to the location information management server 6, when the server 6 receives the movement trajectory basic information transmitted from the base station 2 at a certain time interval (for example, several hours) or at a specific location (near the school gate), It is also possible to create an e-mail containing the latest received movement trajectory basic information and automatically distribute it to the e-mail address of the personal information received earlier. In this case, it is necessary to consider concealing radio wave information and encrypting information contents so that personal information is not known to others on a public line such as the Internet line.

(6) The reference times of the base station 2, the mobile station 3, and the relay station 4 may be configured to automatically match those of the location information management server 6. Thus, accurate movement trajectory basic information can be obtained.
