Description

  The present invention relates to a countermeasure for theft of a mobile object such as a vehicle by searching for a position of a terminal to be searched in a mobile communication system.

Conventionally, since a vehicle can be self-propelled, there is a problem that it is carried to a remote place by a thief. Therefore, in recent years, there is an anti-theft device that finds a stolen vehicle by monitoring the position of the stolen vehicle by using a vehicle position detection technology and a communication system that are widely used in navigation devices (for example, patents). Reference 1).
Japanese Patent Laying-Open No. 2003-54369 ([0041] to [0043], FIG. 5).

  However, in the anti-theft device as described above, since only the position of the stolen vehicle can be grasped, the criminal who is caught is only the current criminal, and if the criminal escapes, it cannot often be arrested . In addition, it is difficult to identify a criminal by a criminal or a criminal who has repeatedly committed crimes and is familiar with the crime.

  By the way, in recent years, mobile phones have been remarkably widespread, and often have one mobile phone for each person. In addition, the mobile phone terminal automatically performs location registration in order to communicate with the base station, so that the location can be specified.

  The present invention has been made in view of the problem that it is difficult to identify a theft crime as described above. By monitoring the position of the vehicle and the mobile phone terminal that moves in the same manner as the vehicle, the suspected theft can be identified. It aims to be.

Then, based on the acquired position information of the vehicle, the terminal detecting means detects a mobile terminal existing around the vehicle, and specifies that the detected mobile terminal information is acquired by the terminal information acquiring means. To do.

  A burglar is always in the vicinity of the vehicle at the time of theft, and for example, there is a high possibility that he / she has a portable terminal such as a cellular phone. Therefore, it is possible to identify a portable terminal that is believed to be possessed by a theft crime by detecting a portable terminal that is present around the vehicle when the vehicle is stolen. And it becomes possible to identify the suspected theft by acquiring the information of the specified portable terminal.

  According to the second aspect of the present invention, the position information acquisition unit acquires the position information of the vehicle in advance, detects the mobile terminal existing around the vehicle based on the position information acquired by the terminal detection unit, and the terminal The detection result by the detection means is stored by the storage means. When the theft detection means detects the theft, the extraction means stores the portable terminal turned off around the vehicle before the theft detection and / or the portable terminal turned on around the vehicle after the vehicle stops The terminal information acquisition means acquires the information of the portable terminal extracted from the information and / or the information of the portable terminal stored in the storage means extracted by the specifying means.

  Therefore, even when a theft offender commits a crime by turning off the power of the mobile terminal, it is possible to identify a more likely suspect by extracting the mobile terminal that is turned off or on It becomes. Further, if the detection result is stored for several days or weeks by the storage means, it becomes easy to identify the theft offender who measures the crime preview or the timing of the crime.

  Further, according to the invention described in claim 3, in the invention described in claim 1 or 2, information on the portable terminal detected in the past around the stolen vehicle by the past recording means is stored, and the weighting means Thus, the mobile terminals detected by the terminal detection means and stored in the past recording means are weighted as particularly important mobile terminals. The terminal information acquisition means preferentially acquires weighted mobile terminal information. According to this, it becomes easy to specify a portable terminal owned by a suspect who repeatedly commits a crime, and it becomes easy to identify a suspect who repeatedly commits a crime based on the mobile terminal information.

  In the invention according to claim 4, in the invention according to any one of claims 1 to 3, the position information of the vehicle is acquired by the position information acquisition means at a predetermined time interval and / or a predetermined displacement interval of the position information. The terminal detection means detects mobile terminals existing around the vehicle based on the acquired position information every time the position information is acquired. And the information of the portable terminal which moves similarly to the movement of a vehicle is acquired by a terminal information acquisition means, It is characterized by the above-mentioned.

  A portable terminal that moves in the same manner as the movement of the vehicle is likely to be a portable terminal possessed by a thief who is moving the vehicle. Therefore, it is easy to identify the suspect by detecting the mobile terminal around the vehicle accompanying the movement of the vehicle and acquiring the information of the mobile terminal.

  According to the invention described in claim 5, the information of the mobile terminal according to any one of claims 1 to 4 includes at least the unique information of the terminal, the date of purchase, the place of purchase, the owner's One of the name and the address of the owner is included. Therefore, when a plurality of portable terminals are detected and it is difficult to identify the suspect, it is possible to narrow down the suspect based on the information. For example, it is possible to search for the possibility of a crime by collating the position of the stolen vehicle with the purchased place or the address of the owner.

  According to the invention described in claim 6, the position information acquisition unit acquires the position information of the vehicle, detects the mobile terminal existing around the vehicle based on the position information acquired by the terminal detection unit, and the terminal information The information of the portable terminal detected by the acquisition means is acquired. Therefore, by detecting a portable terminal that exists in the vicinity of the stolen vehicle, it becomes possible to obtain information on the suspected theft (mobile terminal information owned by the suspect) and to identify the suspect.

  In the seventh aspect of the invention, each time the position information acquisition means acquires the position information of the vehicle, the mobile terminal existing around the vehicle is detected, and based on the detection result, the extraction means detects the movement of the vehicle. Similarly, mobile terminals that move are extracted. And the information of the portable terminal extracted by the extraction means is acquired by the terminal information acquisition means. Thereby, it becomes possible to detect the portable terminal possessed by the suspect based on a plurality of pieces of information, and the identification of the suspect becomes easy.

(First embodiment)
Hereinafter, an embodiment in which the present invention is applied to a terminal detection system including a theft detection apparatus and a mobile phone center will be described with reference to FIGS.

  FIG. 1 is a diagram showing an outline of a terminal detection system in the present embodiment. The theft detection device 1 is a device attached to a vehicle, and is a device that performs vehicle theft detection, own vehicle position detection, and transmission of detection information (configuration will be described later). The mobile phone center 2 is a facility that receives location information from the theft detection device 1, collects location registration information from the base station, and extracts mobile phones that move with the vehicle. The police 3 is an institution that identifies the suspect from the mobile phone information extracted by the mobile phone center 2.

  Next, the whole structure of the theft detection apparatus 1 in this embodiment is demonstrated using FIG. The theft detection device 1 includes a communication means 11, a control circuit 12, and a memory 13. Information communication with the navigation device 14 and signal input from sensors that detect theft such as the key sensor 15, the far infrared sensor 16, and the tilt sensor 17 are provided. Receive. The navigation device 14 is assumed to include current position detection means 20 including a known GPS receiver, gyroscope, vehicle speed sensor, and the like.

  The communication means 11 is composed of a small antenna such as a loop antenna or a microstrip antenna and a communication I / F, and transmits transmission data (the stolen car information and position information in this embodiment mobile phone) input from the control circuit 12. The signal is converted into a signal and transmitted, or the received signal from the outside is subjected to signal processing and output to the control circuit 12. The control circuit 12 includes computer means such as a microcomputer, and includes a well-known CPU, ROM, RAM, I / O, and a bus line for connecting these configurations. . The ROM stores an execution program, a part of the communication program, and the like, and the RAM temporarily stores data necessary for executing the program. And the control circuit 12 is provided with the function to perform various control processing at the time of the detection of theft mentioned later and transmission of the own vehicle position by executing various programs.

  The memory 13 is composed of a writable non-volatile storage medium such as an HDD or a flash ROM, and the vehicle position information obtained from the navigation device 14, the vehicle number, input data from various sensors at the time of theft, etc. must not be deleted. Used as a storage medium for storing data.

  The key sensor 15 is a sensor that outputs a signal when the key is not used by detecting whether or not the lock is released by checking the security code given to the key. In addition, the key sensor 15 may detect not only whether the lock is released with the key but also detect whether the engine is started with the key and output a signal.

  Further, the far-infrared sensor 16 and the inclination sensor 17 are configured in the same manner as the conventional one, and are sensors that detect the intrusion of a person into the vehicle compartment or the movement by a tow truck and output a signal to the control circuit 12. In addition to the key sensor 15, far-infrared sensor 16, and tilt sensor 17, a vehicle theft may be detected using a vehicle speed sensor, a yaw rate, a G sensor, or the like provided in the navigation device 14. Further, a vehicle interior camera may be provided so that the situation in the vehicle interior at the time of theft can be grasped.

  In the above configuration, in the terminal detection system, first, when the theft detection device 1 attached to the vehicle detects the theft of the vehicle, the mobile phone center 2 and the police 3 are notified of the occurrence of the theft, and the vehicle location information is displayed. Send regularly. Next, the mobile phone center 2 that has received the report detects mobile phone terminals existing around the vehicle based on the received vehicle position information, and extracts mobile terminals that move in the same manner as the movement of the vehicle. Then, the mobile phone center 2 reports the extracted mobile terminal information to the police 3.

  Hereinafter, processing performed in the theft detection device 1 and the mobile phone center 2 will be described with reference to FIGS. FIG. 3 is a flowchart showing processing by the control circuit 12 of the theft detection device 1 attached to the vehicle, and a program for executing this flowchart is stored in the ROM of the control circuit 12. The process performed by the theft detection device 1 is a process that starts after the vehicle is parked or after the door is locked, and a process of detecting theft from steps (hereinafter abbreviated as S) 300 to S304 shown in FIG. And processes of transmitting information from S305 to S308 can be roughly divided into two processes.

  In FIG. 3, it is determined whether or not a theft call from the user has been received in S300. The theft call is a signal transmitted to the communication means 11 of the theft detection device 1 when the user confirms the theft of the vehicle, and is transmitted from a mobile phone or the like owned by the user. If it is determined that the theft call from the user has been received (S300: YES), it is determined that the vehicle has been stolen, and the process proceeds to S305. On the other hand, when it is determined that the theft call from the user has not been received (S300: No), it is determined whether or not a person has entered (S301).

  Whether or not a person has entered is determined by detecting an input from the far-infrared sensor 16 or the tilt sensor 17. An input signal from the far infrared sensor 16 can detect that something has blocked the far infrared ray in the vehicle interior and determine that someone has entered the vehicle interior. Further, by detecting the inclination of the vehicle that occurs when a person enters the vehicle from the inclination sensor 17, it is possible to determine that someone has entered the vehicle interior.

  If it is determined in S301 that a person has entered (S301: YES), the process proceeds to S304. If it is determined in S301 that no person has entered (S301: NO), it is determined in S302 whether or not the vehicle has moved. Here, it is determined whether or not the vehicle has moved by using a vehicle speed sensor (not shown) constituting the current position detecting means 20 provided in the navigation device 14.

  When it is determined that the vehicle has moved (S302: YES), the process proceeds to S304, and when it is determined that the vehicle has not moved (S302: NO), the process proceeds to S303. In the determination in S302, the movement of the vehicle may be determined using a yaw rate, a G sensor, or the like instead of the vehicle speed sensor. In S303, it is determined whether the vehicle inclination angle is equal to or greater than a predetermined value. In this determination, in consideration of the case where the vehicle is moved by a tow person, an affirmative determination is made when the vehicle is tilted by a predetermined value (for example, 10 degrees) or more.

  If it is determined that the vehicle inclination angle is less than the predetermined value (S303: NO), it is determined that no vehicle theft has been detected, and the process proceeds to S300. On the other hand, when it is determined that the vehicle inclination angle is equal to or greater than the predetermined value (S303: YES), the process proceeds to S304.

  When it is determined that a person has entered the vehicle (S301: YES), when it is determined that the vehicle has moved (S302: YES), or when the inclination angle of the vehicle is greater than or equal to a predetermined value (S303: YES), in S304, it is determined whether or not the door is opened using the key. Here, the determination is performed using an input signal from the key sensor 15. Based on the input signal from the key sensor 15, it is possible to determine whether or not the door of the vehicle has been opened illegally without using the key.

  If it is determined in S304 that the door has been opened using the key (S304: YES), it can be determined that the user has boarded the vehicle using the key, and there is no abnormality in which the vehicle is stolen. Judge and shift to S300. On the other hand, when it is determined that the door has been opened without using the key (S304: NO), it is determined that the vehicle has been stolen, and the process of transmitting information is started. Note that the determination processing from S301 to S304 described above is processing for automatically detecting the theft in the theft detection device 1. The determination of theft may be performed by combining input signals from the sensors used for the above determination, or a sensor other than the above sensors (for example, a sensor that detects breakage of the window glass) may be used.

  When there is a theft call from the user (S300: YES), or when it is determined that the door is opened without using the key (S304: NO), the theft is detected and the vehicle information transmission process is performed (S305). ). In the vehicle information transmission process performed in S305, the vehicle information is transmitted to the mobile phone center 2 via the communication unit 11. As shown in FIG. 4, the transmitted information includes vehicle position information (theft car position) detected from the current position detection means 20 of the navigation device 14, and vehicle specific information (vehicle number: vehicle) stored in the memory 13. ID) and input data from various sensors (theft information, vehicle interior information). In addition, when the vehicle interior camera is provided, you may make it also transmit the image image | photographed with the vehicle interior camera.

  After transmitting vehicle information in S305, it is determined in S306 whether or not the vehicle has moved a certain distance (for example, 50 m) from the previous transmission of vehicle information. This determination is made based on the displacement of the host vehicle position acquired from the current position detection means 20 or the movement distance detected from an input signal such as a vehicle speed sensor. When it is determined that the vehicle has moved a certain distance from the previous transmission of vehicle information (S306: YES), the process proceeds to S305, and the vehicle information is transmitted again. On the other hand, when it is determined that the vehicle has not moved a certain distance (S306: NO), the process proceeds to S307, and it is determined whether or not a certain time (for example, 30 seconds) has elapsed since the previous transmission of the vehicle information.

  When it is determined that a certain time has elapsed since the previous transmission of the vehicle information (S307: YES), the process proceeds to S305 and the vehicle information is transmitted again. On the other hand, when it is determined that the vehicle has not passed for a certain period of time (S307: NO), the process proceeds to S308, and it is determined whether there is an input for ending the process of transmitting information. When it determines with the input which complete | finishes the process of information transmission not being performed (S308: NO), it transfers to S306 and determines the transmission timing of vehicle information repeatedly. On the other hand, when it is determined that an input for ending the information transmission process has been performed (S308: YES), the process in the theft detection device 1 ends.

  Note that the input for ending the information transmission process is performed by the user, and is performed by starting the engine using a key or inputting communication via a mobile phone. Further, the vehicle information to the mobile phone center 2 may be transmitted at any one timing every time the vehicle moves a certain distance or every certain time. That is, only one of S306 and S307 may be determined.

  Next, processing performed in the mobile phone center 2 will be described with reference to FIGS. FIG. 5 is a flowchart showing processing performed in the mobile phone center 2. In FIG. 5, it is first determined in S500 whether vehicle information from the theft detection device 1 has been received. This determination is repeated until vehicle information is received. When it is determined that vehicle information has been received (S500: YES), the process proceeds to S501. In S501, a vehicle ID (vehicle number) is extracted from the received vehicle information, and it is determined which stolen vehicle information is based on the vehicle ID.

  Thereafter, the processing from S502 to S508 is performed on the stolen vehicle determined in S501. In S502, the position of the stolen vehicle is specified based on the received vehicle information, and a mobile phone existing in the vicinity (for example, within a radius of 200 m) is detected. A method of detecting a mobile phone existing around the stolen vehicle is performed based on location registration information that is performed so that the base station of the mobile phone can communicate with the mobile phone.

  In order to communicate with the base station, the mobile phone needs to register with which base station to communicate. Therefore, it is possible to detect the mobile phone existing at the position from the position information. In the case of cell communication, the position of the mobile phone can be detected for each radio wave output range (communication cell) of the base station.

In S503, it is determined whether or not the vehicle information of the stolen vehicle specified by the vehicle ID is received for the first time. In addition, it is determined based on the presence or absence of the search file linked | related with vehicle ID whether it is the first time. If it is determined that the vehicle information is received for the first time (S503: YES), a search file associated with the vehicle ID is created, and all mobile phone numbers detected in S502 around the location of the stolen vehicle are listed. It outputs to a search file (S505), and transfers to S506. For example, as shown in Figure 6a, when detecting the mobile phone 1 to 11 around the position A ₀ in the stolen vehicle is present, the number of mobile phone the mobile phone 1 to 11 is to be all recorded in the search file .

  On the other hand, if it is determined that the vehicle information is not received for the first time (S503: NO, FIG. 6b), the communication cell in which the position indicated by the vehicle position information is present and the communication cell in which the position indicated by the previously received position information is present. Are the same (S504). When it is determined that the communication cell where the position indicated by the position information of the vehicle is the same cell as the previous time (S504: NO), the process proceeds to S507.

If it is determined that the communication cell where the stolen vehicle is located is not the same communication cell as the previous one (S504: YES), the mobile phone number detected in S502 among the mobile phone numbers stored in the search file. Only the same number is left, and the numbers of the other mobile phones are deleted (S506). For example, the mobile phones 1 to 11 have been recorded in the search file as a detection result for the vehicle position A ₀ as shown in FIG. 6a last time, and the mobile phone 1 for the vehicle position A ₁ as shown in FIG. When -4, 6, 10-14 are detected, the numbers of the mobile phones 1, 2, 3, 4, 6, 10, 11 are left in the search file.

  After the search result is recorded in the search file in S506, it is determined in S507 whether or not the specified stolen vehicle has been processed a predetermined number of times (for example, 5 times). If the number is less than the predetermined number (S507: NO), the process ends as it is, and if the number is the predetermined number or more (S507: YES), the movement locus information and the search file of the stolen vehicle are transmitted to the police 3 (S508).

  In this way, the mobile phone center 2 can repeatedly receive the position of the stolen vehicle and detect the mobile phone existing around the stolen vehicle, thereby extracting the number of the mobile phone that moves with the stolen vehicle. . Further, the stolen vehicle can be found and the suspect can be identified based on the search result in the mobile phone center 2. When the mobile phone center 2 determines the vehicle ID (S501), it searches the registered vehicle information from the Ministry of Transport etc. to find the owner of the stolen vehicle and its contact information, and informs the owner of the theft. You may make it contact.

  As described above, when the theft detection device 1 attached to the vehicle detects a theft by the terminal detection system in the present embodiment, the vehicle information is transmitted to the mobile phone center 2, and the mobile phone center 2 based on the received vehicle information. Allows extraction of mobile phones that move with the vehicle. That is, the owner can be identified from the number of the mobile phone that moves with the stolen vehicle, and the suspect of theft can be identified by monitoring the location of the vehicle and the mobile phone terminal that moves in the same manner as the vehicle. .

  In the present embodiment, the position of the vehicle is detected and transmitted from the navigation device 14 attached to the vehicle. However, information on a mobile phone (for example, a car phone) attached to the vehicle and other wireless devices is used. Thus, the position information of the vehicle may be automatically determined on the mobile phone center 2 side. That is, information such as a mobile phone attached to the vehicle in advance is registered in the mobile phone center 2, and the mobile phone center 2 receives the vehicle information transmitted from the theft detection device 1 after the theft detection. The position information of the vehicle can be detected from the position registration information of the mobile phone attached to the vehicle in the same manner as other mobile phones. In that case, the theft detection device 1 only needs to transmit the theft car information.

  Also, in order not to accidentally report the user's mobile phone to the police 3 as a theft, the user's mobile phone number is registered in advance in the mobile phone center 2 or a confirmation call is made before the notification. You may do it.

  Further, the mobile phone information (for example, purchase date / time and location, owner's name and address, mobile phone theft information, etc.) is searched from a database of a telephone company etc. from the extracted mobile phone number. May be transmitted to the police 3 together with the movement trajectory information of the stolen vehicle and the search file in S508. As a result, it is possible to further facilitate the identification of the theft by comparing the theft position of the vehicle with the address of the owner.

  Furthermore, mobile phone numbers detected around the past stolen vehicle may be stored in a database and collated with the extracted mobile phone numbers. This makes it possible to identify suspects of specialized theft crimes and theft groups who repeatedly commit crimes.

  In the present embodiment, when the theft is detected, the transmission of the position information is started. However, the mobile phone center 2 may always grasp the position information of the vehicle. In that case, it is possible to monitor a mobile phone detected around the vehicle before theft. In addition, based on the mobile phone information detected around the vehicle before the theft, the mobile phone that was turned on was detected around the stop position of the vehicle, or the power was cut off within a certain range around the vehicle before the theft You may make it index a mobile telephone. As a result, even when the burglar steals by turning off the power of the cellular phone, the cellular phone possessed by the burglar can be specified.

  Moreover, when a burglar removes the communication device, a mechanism for detecting that the engine computer has been removed through the LAN and stopping the engine can be included.

  And although this embodiment showed what was targeted at theft of vehicles, position information can be acquired not only in vehicles but also in other mobile objects (bicycles, motorcycles, etc.) and can be applied in the same manner. .
