Description

  The present invention relates to a moving object monitoring apparatus, a moving object monitoring method, a moving object monitoring system, and a computer program.

  In recent years, with the widespread use of mobile communication terminals such as mobile phones and increased awareness of social crime prevention, the location of specific mobile terminals is always identified and monitored, and in advance as required. Services such as notification of this location information to registered report destinations are provided by many vendors, and it is spreading to ordinary households.

  As this type of technology, Patent Document 1 (Japanese Patent Application Laid-Open No. 2001-186558) receives base station identification information and its reception level from at least one base station with which a mobile communication terminal communicates, and registers in advance from these. A method for determining whether or not the vehicle has deviated from the area and notifying the position information confirmation device when it is determined that the vehicle has deviated is described.

Further, in Patent Document 2 (Japanese Patent Laid-Open No. 2002-99971), an allowable area where the location of the mobile terminal is allowed is registered in advance in the database, and the acquired current position information of the mobile terminal is within the registered allowable area. It is described whether or not the mobile terminal is confirmed and notified when it is out of the allowable range, and when there is no response to this, a method for notifying the third party is described. In addition, there is also described a method of additionally registering the current position information as an allowable area when there is a response to the confirmation message.

  However, the above technique has room for improvement in the following points. The monitoring area (allowable area) where the mobile communication terminal is allowed to be registered must be registered in advance. In these monitoring methods, there is no problem if the movement range of the monitored person is within the pre-registered monitoring area, but if the monitored person is active outside the monitoring area, an unnecessary report may occur. is there. For example, when a guardian (monitoring person) has a child (monitored person) carrying the mobile communication terminal used in the above technology, when the guardian and the child are acting together, the child Even if you go outside, your child is under the supervision of a parent and does not need to be reported. However, in such a case, if all the movement routes are not registered in the monitoring area in advance in the technique of Patent Document 1, the position information confirmation device is notified as needed. In the same case, in the technique of Patent Document 2, confirmation is made every time the person to be monitored moves out of the allowable area, and a response must be made.

  ADVANTAGE OF THE INVENTION According to this invention, the mobile body monitoring apparatus, the mobile body monitoring method, the mobile body monitoring system, and computer program which avoid a report when a some mobile communication terminal is located in the same local area are provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same reference numerals are given to the same components, and the description will be omitted as appropriate.

  FIG. 1 is a schematic view of a moving object monitoring system according to an embodiment of the present invention. The mobile monitoring system 1 of this embodiment includes mobile communication terminals 10A and 10B, a fixed terminal 20, a mobile monitoring device 30, radio base stations 40A and 40B, GPS satellites 50A, 50B and 50C, and GPS positioning. It consists of a device 60 and a network 70. 1 is a monitoring area registered in advance in the mobile communication terminal 10A, and communication areas 90A and 90B are communication areas of the radio base stations 40A and 40B, respectively. There are some overlapping boundaries.

  The mobile body monitoring system 1 acquires a plurality of pieces of position information representing the current positions of the plurality of mobile communication terminals 10A and 10B and the plurality of mobile communication terminals 10A and 10B, and monitors the plurality of mobile communication terminals 10A and 10B. It is determined whether or not the first position information indicating the current position of the target first mobile communication terminal 10A is included in the monitoring area information indicating the monitoring area 80 registered in advance, and the first position information and the plurality of mobile communication terminals 10A. 10B, whether the first mobile communication terminal 10A and the second mobile communication terminal 10B are located in the same local area by collating with the second position information indicating the current position of the second mobile communication terminal 10B. When the first location information is not included in the monitoring area information and the first mobile communication terminal 10A and the second mobile communication terminal 10B are not located in the same local area , A moving object monitoring device 30 for sending an alarm to at least one of the second mobile communication terminal 10B and preset another terminal (fixed terminal 20), can comprise a. Here, the other terminal (fixed terminal 20) set in advance is a personal computer or the like installed in the home of the subscriber of the mobile monitoring system 1.

  In the present embodiment, the position information is at least one of the area code defined in the radio base stations 40A and 40B with which the mobile communication terminals 10A and 10B communicate and the GPS information obtained by positioning the mobile communication terminal 10 with the GPS system. May be included.

  Here, the details of the area code determined by the radio base station 40 will be described. For the purpose of providing location information services to mobile communication terminals, communication carriers and the like divide their communication service areas into a plurality of areas and assign area codes to the respective areas. Each area is provided with at least one radio base station 40, and the radio base station 40 can transmit the area code of the area to which it belongs to the mobile communication terminal 10 in communication. That is, in FIG. 1, since the mobile communication terminal 10B is located in the communication area 90B of the radio base station 40B, the mobile communication terminal 10B can receive the area code defined for the radio base station 40B. The mobile communication terminal 10A belongs to both the communication area 90A of the radio base station 40A and the communication area 90B of the radio base station 40B. Therefore, when communicating with the radio base station 40A, the area code defined for the radio base station 40A can be received. When communicating with the radio base station 40B, the area code defined for the radio base station 40B is received. it can.

  Next, details of GPS information obtained by positioning the mobile communication terminal 10 by GPS will be described. The GPS (Global Positioning System) can determine the latitude, longitude, altitude, etc. of a terminal that receives a GPS signal with an error of several meters to several tens of meters using a signal transmitted from a GPS satellite 50. it can. Therefore, in order to position the mobile communication terminal 10 using GPS, it is essential that the mobile communication terminal 10 be configured to receive GPS signals. The configuration of the mobile communication terminal 10 will be described later.

  The first mobile communication terminal 10 </ b> A receives a plurality of GPS signals from each of the plurality of GPS satellites 50 </ b> A, 50 </ b> B, and 50 </ b> C and sends the received GPS signals to the GPS positioning device 60. The GPS positioning device 60 determines the position of the first mobile communication terminal 10A from the time when the plurality of GPS satellites 50A, 50B, 50C transmit each GPS signal and the time when the first mobile communication terminal 10A receives each GPS signal. Can be calculated. In this embodiment, since GPS signals are received from the three GPS satellites 50A, 50B, and 50C, the GPS positioning device 60 can calculate longitude and latitude. Although not shown, if GPS signals are received from four or more GPS satellites, the GPS positioning device 60 can calculate altitude in addition to latitude and longitude. The result measured by the GPS positioning device 60 is sent to the first mobile communication terminal 10A and the mobile monitoring device 30 as the first GPS information. The positioning is similarly performed for the second mobile communication terminal 10B, and the measurement result is transmitted to the second mobile communication terminal 10B and the mobile monitoring device 30 as second GPS information.

  There are advantages and disadvantages between using an area code and a GPS positioning result as position information used in the mobile monitoring system 1 of the present embodiment. First, as a disadvantage of using an area code for position information, since the range represented by the area code is relatively wide, even the mobile communication terminals 10 that receive the same area code are located at the same position. It's hard to say. Further, the shape of the monitoring area registered in advance and the range represented by the area code do not match. As described above, since the range represented by the area code depends on the communication area 90 of the radio base station 40, its shape changes from time to time depending on the communication environment, and cannot exactly match the shape of the monitoring area. Furthermore, when the mobile communication terminal 10 exists at the boundary of the communication area 90 as shown in FIG. 1, the received area code may change even if the mobile communication terminal 10 continues to be located at the same point. As an advantage in the case of using an area code for position information, power consumption can be suppressed because the load of communication processing of the mobile communication terminal 10 is relatively low. In urban areas, there are many places where communication is possible even in buildings or underground, so the probability of communication interruption is relatively low. Next, as a disadvantage of using the GPS positioning result for the position information, the load of communication processing of the mobile communication terminal 10 is relatively high, so that the power consumption increases and it is not suitable for long-time monitoring. In addition, in areas where there are obstacles such as underground, tunnels, forests, and dense buildings, the signal from the GPS satellite 50 does not reach and positioning of the mobile communication terminal 10 becomes impossible. Next, as an advantage of using GPS positioning results for position information, it is relatively accurate, so it is easy to determine where the same position is located, and the shape of the registered monitoring area is almost the same Can be the monitoring area. As described above, since each method has advantages and disadvantages, in the present embodiment, both are used in combination.

  FIG. 2 is a configuration diagram of the mobile communication terminal 10 according to the present embodiment. A GPS receiving unit 11 that receives a GPS signal arriving from a GPS satellite 50, a base station receiving unit 12 that receives a signal arriving from a radio base station 40, and an operation input unit 13 that inputs a user operation using a numeric keypad, a touch panel, or the like. And a communication unit 14 that transmits a signal to the radio base station 40 and the like, and a control unit 15 that controls the operation of the mobile communication terminal 10. When the mobile object monitoring system 1 combines area codes and GPS positioning results and handles them as position information, the mobile communication terminal 10 needs to include both a GPS receiver 11 and a base station receiver 12.

  FIG. 3 is a configuration diagram of the moving object monitoring apparatus 30 according to the present embodiment. The mobile monitoring device 30 stores a location information acquisition unit 31 that acquires a plurality of location information that represents the current location of each of the plurality of mobile communication terminals 10A and 10B, and a storage that stores monitoring area information that represents a monitoring area 80 registered in advance. Unit 32 and a current position determination unit 33 that determines whether or not the monitoring area information includes the first position information indicating the current position of the first mobile communication terminal 10A to be monitored among the plurality of mobile communication terminals 10A and 10B. The first position information and the second position information indicating the current position of the second mobile communication terminal 10B among the plurality of mobile communication terminals 10A and 10B are collated, thereby the first mobile communication terminal 10A and the second mobile communication terminal The same position determination unit 34 that determines whether or not 10B is located in the same local area, and the first mobile communication terminal 10 when the first position information is not included in the monitoring area information When the second mobile communication terminal 10B and the second mobile communication terminal 10B are not located in the same local area, a notification unit that sends an alarm to at least one of the second mobile communication terminal 10B and another preset terminal (fixed terminal 20) 35.

  All or part of the configuration of the mobile monitoring apparatus 30 according to the present embodiment may be realized by hardware, or may be realized by a computer program (or program code) that causes a processor to execute processing. . The processor reads and executes the computer program from a recording medium such as a nonvolatile memory.

  When the functions of the position information acquisition unit 31, the current position determination unit 33, the position determination unit 34, and the notification unit 35 are realized by a computer program, the computer program sets the current positions of the plurality of mobile communication terminals 10A and 10B, respectively. A monitoring area 80 in which position information acquisition processing for acquiring a plurality of position information to be represented and first position information indicating the current position of the first mobile communication terminal 10A to be monitored among the plurality of mobile communication terminals 10A and 10B are registered in advance. Current position determination processing for determining whether or not it is included in the monitoring area information representing the first position information and second position information representing the current position of the second mobile communication terminal 10B among the plurality of mobile communication terminals 10A and 10B; A peer that determines whether or not the first mobile communication terminal 10A and the second mobile communication terminal 10B are located in the same local region by collating When the determination process and the first location information are not included in the monitoring area information, and when the first mobile communication terminal 10A and the second mobile communication terminal 10B are not located in the same local area, the second mobile communication terminal 10B In addition, it is possible to execute notification processing for sending an alarm to at least one of other preset terminals (fixed terminal 20).

  The location information acquisition unit 31 periodically acquires location information representing the current location of some or all of the plurality of mobile communication terminals 10A, 10B via the network 70. Although it is desirable that the timings for acquiring the position information from the plurality of mobile communication terminals 10 be the same, the error may be allowed to some extent. The network 70 may include a communication network such as the Internet and a LAN, and devices such as a server device and a base station control device.

  In the present embodiment, the moving body monitoring device 30 includes a database unit 36 that stores the position information acquired by the position information acquisition unit 31, and the current position determination unit 33 and the same position determination unit 34 are respectively located from the database unit 36. Information may be acquired. As a result, the position information of each of the plurality of mobile communication terminals 10A and 10B can be recorded, and the current position determination unit 33 and the same position determination unit 34 can acquire the position information from the database unit 36 when necessary. it can.

  The storage unit 32 stores monitoring area information representing the monitoring area 80 registered in advance. The monitoring area information can be registered from the mobile communication terminal 10, the fixed terminal 20, or the like. For example, registration by specifying a monitoring area by address (XX city △△ town □□ chome, etc.), or registering a location identified by searching for a location on the mobile communication terminal 10 (latitude ●● °, longitude ▲ Display the map on the touch screen type display screen within the radius of □ ° or within the radius of □ m, or the wireless base station 40 communicated during the search, etc., and the points directly plotted on the map There are registration methods such as registering as an area. Such monitoring area information is sent to and stored in the storage unit 32 via the radio base station 40 and the network 70.

  The current position determination unit 33 can determine whether the position information acquired from the database unit 36 is included in the monitoring area information acquired from the storage unit 32.

  The position determination unit 34 can check whether or not the plurality of mobile communication terminals 10A and 10B are located in the same local region by collating a plurality of pieces of position information acquired from the database unit 36. Details of the determination method of the position determination unit 34 will be described below.

  A determination method of the position determination unit 34 when GPS information is acquired as position information will be described. The position determination unit 34 includes first GPS information obtained by positioning the first mobile communication terminal as first position information from the database unit 36, and second GPS obtained by positioning the second mobile communication terminal as second position information. If the first mobile communication terminal and the second mobile communication terminal are not located in the same local area when the information is acquired and collated and the difference between the first GPS information and the first GPS information is outside the predetermined range Can be determined. In addition, the position determination unit 34 is obtained by positioning the first mobile communication terminal as the first position information from the database unit 36 and the second mobile communication terminal as the second position information. When the second GPS information is acquired and collated, and the difference between the first GPS information and the first GPS information is within a predetermined range, the first mobile communication terminal and the second mobile communication terminal are located in the same local region. Can be determined. The GPS information may include altitude as well as latitude and longitude. Further, the predetermined range is limited by the accuracy of the GPS information, and it is necessary to allow at least several meters.

  A determination method of the position determination unit 34 when an area code is acquired as position information will be described. First, when the first mobile communication terminal 10A and the second mobile communication terminal 10B are communicating with the same radio base station 40B, since the received area codes are the same, the first position information and the second position information Is the same. Therefore, the same position determination unit 34 collates the first position information and the second position information, and determines that the first mobile communication terminal 10A and the second mobile communication terminal 10B are located in the same local region. Can do. Next, the same location determination unit 34 receives the first area code determined from the database unit 36 as the first location information for the radio base station 40A with which the first mobile communication terminal 10A is communicating, and the second location information as the second location information. When the first area code and the second area code are different when the second area code determined for the radio base station 40B with which the mobile communication terminal 10B is communicating is acquired and collated (the radio base station 40A and the radio base station 40B) 1A and 2B, it can be determined that the first mobile communication terminal 10A and the second mobile communication terminal 10B are not located in the same local area. Furthermore, the same position determination unit 34 uses the first area code defined in the radio base station 40A with which the first mobile communication terminal 10A is communicating as the first position information from the database unit 36, and the second movement as the second position information. The second area code determined for the radio base station 40B with which the communication terminal 10B is communicating is acquired and collated, and when the first area code and the second area code are the same (the radio base station 40A and the radio base station 40B When the belonging areas are the same), it can be determined that the first mobile communication terminal 10A and the second mobile communication terminal 10B are located in the same local area.

  In the present embodiment, since a method of handling GPS information as position information and a method of handling area codes as position information are used, the position determination unit 34 can determine by combining both conditions.

  When the same position determination unit 34 determines that the first mobile communication terminal 10A and the second mobile communication terminal 10B are located in the same local area, the first position information and the second position information are associated with each other. The position information may be stored in the database unit 36. Thereby, the same position information indicating that the first mobile communication terminal 10A and the second mobile communication terminal 10B are located in the same local area can be recorded.

  When the first position information is not included in the monitoring area information and the first position information does not match the second position information as a result of the determination by the current position determination section 33 and the same position determination section 34 An alarm can be sent to a plurality of mobile communication terminals 10A, 10B and other terminals (fixed terminal 20).

  Further, as a result of the determination by the current position determination unit 33 and the same position determination unit 34, when the first position information is not included in the monitoring area information, the first mobile communication terminal 10A and the second mobile communication terminal 10B are the same local When located in the area, the reporting unit 35 acquires the same location information from the database unit 36 and uses the same location information as at least one of the second mobile communication terminal 10B and the other terminal (fixed terminal 20). May be sent to As a result, the person carrying the second mobile communication terminal 10B or the user of the fixed terminal 20 is notified that the monitored person has moved out of the monitoring area together with the monitoring person (or a person corresponding to the monitoring person). Is done.

  In the present embodiment, a speed calculating unit 37 that calculates the moving speed of the mobile communication terminals 10A and 10B based on GPS information may be provided, and the same position determining unit 34 may determine based on the moving speed. In this case, the speed calculation unit 37 stores the movement speed in association with the position information in the database unit 36, and the position determination unit 34 receives the first movement speed and the second movement rate associated with the first position information from the database unit 36. When the second movement speed associated with the position information is acquired and the difference between the first movement speed and the second movement speed is outside the predetermined range, the first mobile communication terminal 10A and the second mobile communication terminal 10B are the same. It may be determined that it is not located in the local region. Thereby, since the moving speed of the mobile communication terminal 10 can be included in the determination condition of the same position determining unit 34, both of the moving speeds of the first mobile communication terminal 10A and the second mobile communication terminal 10B are clearly different. Even if they are positioned temporarily in the same local area, the determination result of the same position determination unit 34 can be NO.

The date and time when the location information is acquired in association with this, the mobile communication terminal ID of the target, the longitude, latitude and altitude of the location where the mobile communication terminal is located, the radio base station with which the mobile communication terminal is communicating Stores information such as area codes. Although not shown here, if the mobile communication terminal 10 is a mobile phone, the contractor name, phone number, mail address, etc. of the mobile phone may be included.

  FIG. 4B is a data table when the determination result of the same position determination unit 34 is stored in the database unit 36. The same position determination ID is assigned by assigning sequence numbers in the order in which the same position determination unit 34 determines the same position. A plurality of position information IDs associated with the same position are stored. The reporting unit 35 can read out a plurality of position information IDs using the same position determination ID as a key, and can read various position information from the data table of FIG. 4A using the read position information ID as a key.

  FIG. 4C is a data table when the moving speed of the mobile communication terminal calculated by the speed calculating unit 37 is stored in the database unit 36 in association with the position information. The reporting unit 35 can read the moving speed from the data table of FIG. 4C using the position information ID as a key.

  When the first position information is not included in the monitoring area information and when the first position information and the second position information match, the reporting unit 35 determines that the first position information and the second mobile communication terminal 10B Information associated with the identification information may be sent to at least one of the plurality of mobile communication terminals 10A and 10B and another terminal (fixed terminal 20).

  FIG. 5 is a flowchart showing the processing procedure of the moving object monitoring method of this embodiment. The processing procedure of the movement monitoring method of the present embodiment includes a position information acquisition step (step S102) for acquiring a plurality of position information respectively representing the current positions of the plurality of mobile communication terminals 10A and 10B, a plurality of mobile communication terminals 10A, Current position determination step for determining whether or not the first position information indicating the current position of the first mobile communication terminal 10A to be monitored in 10B is included in the monitoring area information indicating the monitoring area 80 registered in advance (step S104). The first position information and the second position information indicating the current position of the second mobile communication terminal 10B among the plurality of mobile communication terminals 10A and 10B are collated, thereby the first mobile communication terminal 10A and the second mobile communication terminal The same position determination step (step S105) for determining whether or not 10B is located in the same local area, and the first position information is the monitoring area information When the first mobile communication terminal 10A and the second mobile communication terminal 10B are not located in the same local area (NO in step S105), the second mobile communication terminal 10B And a reporting step (step S106) of sending an alarm to at least one of other preset terminals (fixed terminal 20).

  Further, when the first position information is not included in the monitoring area information (NO in step S104), and when the first mobile communication terminal 10A and the second mobile communication terminal 10B are located in the same local area (step S105). YES), the same position information in which the first position information and the second information are associated with each other is acquired, and the same position information is acquired from at least one of the plurality of mobile communication terminals 10A and 10B and other terminals (fixed terminal 20). There may be provided the same position information sending step (step S107).

  Furthermore, a speed calculating step (step S103) for calculating the moving speed of the mobile communication terminal 10 based on the GPS information may be provided, and the position determining step (step S105) may be determined based on the moving speed.

  If it is determined in the processing procedure of step S101 in FIG. 5 that the processing is to be ended (YES in step S101), the above processing procedure can be ended. On the other hand, when it is determined not to end (NO in step S101), the processing procedure after step S102 can be executed. The time when it is determined to end includes when the mobile monitoring device 30 is turned off, when communication between each component of the mobile monitoring system 1 is cut off for a predetermined time or more.
