JP6799028B2 - Suspicious person estimation system - Google Patents

Description

The present invention relates to a system for estimating a suspicious person who performs suspicious behavior such as a criminal or a stalker when a crime occurs by receiving and analyzing radio waves emitted from a mobile phone.

Crime such as stalking, molester, vandalism, arson, burglary, laundry thief, shoplifting, car puncture, etc. is endless, and many surveillance cameras are installed in the city to prevent crime and search for criminals. In addition, surveillance cameras have been installed in stores such as convenience stores to enhance surveillance capabilities. On the other hand, the spread of mobile phones has become one by one, and most people own mobile phones when they go out, so the whereabouts of criminals and suspicious persons can be determined from the base station information that the mobile phone operator can grasp. It is also possible to search.

Patent Document 1 uses positioning information such as GPS provided by a mobile phone to determine whether there is a suspicious person in a crime-prone area and issues an alarm. Patent Document 2 describes a narrow communication range called a form cell base station. A technique is disclosed in which a base station is provided in a residence and a person who invades the residence is determined to be a suspicious person while determining whether the mobile phone is registered in the fomtocell base station.

Since many surveillance cameras are installed and it can be visually confirmed that they are installed, criminals tend to act while paying attention to the location of the surveillance cameras, such as not being photographed by the surveillance cameras, and are suspicious in Patent Documents 1 and 2. The purpose is to search for behavioral observations of people.

JP 2010-160621 JP 2012-39364

However, the techniques of Patent Documents 1 and 2 are not perfect for the purpose of preventing crimes such as stalking, molestation, car vandalism, burglary, etc. and identifying the criminal, and further search means are required. It is socially important to improve the estimation accuracy of criminals while integrating multiple information such as surveillance camera information, mobile phone information, and sighting information.

The present invention has been made in view of the above points, and identifies and estimates a person who was in a narrow area with a radius of about 10 meters at the time of a crime, and identifies a suspicious person or a criminal based on the specified person list. The purpose is.

In order to achieve the above object, the present invention receives a mobile radio wave generated from within a radius of about 10 meters, demodulates the ID signal of the mobile phone from the received radio wave, and displays a list of restored ID codes together with date and time information. Place the radio wave monitor device to be stored at points where suspicious persons are rampant and crimes are likely to occur, such as houses, restaurants, hotels, parking lots, streets, streets, and station ticket gates, and the ID list detected by the radio wave monitor device is displayed. Send to the management server. The management server manages the list of suspicious persons from the received ID list, sends the suspicious person ID list to the radio wave monitor device, and when the radio wave monitor device finds an ID that matches the suspicious person ID list, , It is characterized by contacting the management server.

The radio wave monitoring device is small and lightweight, can make it invisible that it is installed, and is easy to install at many points. It can also be estimated that suspicious persons such as burglars, laundry thieves, and stalkers are in the vicinity of the home by installing it at the front door of a private home. It is also effective in estimating the criminals of molestation crimes and car vandalism, and the whereabouts of those who have been identified by the police as criminals or who are wanted can be estimated.

It is a figure which shows the whole structure of the suspicious person estimation system by this invention. It is a block diagram which shows the internal structure of the radio wave monitoring device of the suspicious person estimation system by this invention. It is a block diagram which shows the internal structure of the monitor control device which is connected to the radio wave monitor device of the suspicious person estimation system by this invention, and exchanges information with a radio wave monitor device. It is a figure which shows the communication signal which is communicated between a management server and a radio wave monitor device in this invention.

The present invention is based on the premise that the ID code unique to the mobile phone is restored from the radio waves emitted by the mobile phone, that the person is carrying the mobile phone when going out, and the power of the mobile phone is turned on. Is a condition. The ID code unique to the mobile phone includes an ID code as a mobile phone (hereinafter, mobile ID), a Bluetooth radio ID code (hereinafter, BTID) included in the mobile phone, and a WiFi radio ID code (hereinafter, WiFi ID). ). If the owner of the mobile phone does not set Bluetooth or WiFi to use its function, the ID code will not be generated as radio waves from the mobile phone.

In general, many people set the use of the WiFi function to ON, but not many people set the Bluetooth installation to ON, and a typical usage example is a person who uses wireless earphones. There will be.

When the BTID and WiFiID settings are turned on, the ID code is periodically generated to find the connection destination (pairing partner for BT, router for WiFi). The mobile ID is a cellular wireless system, and is generated from the mobile phone in order to periodically check where the base station area is currently located. The periodic cycle described above is on the order of 30 seconds or 1 minute. The mobile ID includes a terminal ID unique to the terminal and a temporary ID (hereinafter, TEMP ID) code generated by the base station. The TEMP ID code is used in place of the terminal ID to prevent the mobile phone from being eavesdropped by a third party, and the base station manages the terminal ID and TEMP ID in association with each mobile phone. ing. The mobile phone transmits the TEMP ID code notified from the base station in place of the terminal ID. When the base station requests that the terminal ID be transmitted, the terminal ID is transmitted from the mobile phone.

In the present invention, demodulation of the above-mentioned three ID codes is attempted, and Table 1 summarizes the features of the three radio systems in terms of radio wave reach, radio wave frequency, and transmission power.

As a commercial embodiment of the present invention, there is a business of a security company, the security company operates a management server, the radio wave monitoring device referred to in the present invention is installed in a customer of the security company, and the security company is a security company. When an accident or crime occurs while operating the management server, the criminal or suspicious person is identified based on the information obtained from the management server and the information linked with the police, mobile phone companies, and mobile phone makers. Will be done.

FIG. 1 is an overall configuration diagram of a suspicious person estimation system according to the present invention, which includes a radio wave monitor device 1, a monitor control device 3, a management server 4, a public wireless communication network 5 such as LTE and PHS, and a mobile phone a owned by a person. , B, ... n. The monitor control device 3 will be described later, but a mobile phone can be used as a substitute. Radio monitor devices 1 are installed in parking lots, in the city, at train station ticket gates, points where molesters and crimes are likely to occur, private residences (entrances, mailboxes, etc.), movie theaters, theaters, hotels, Internet cafes, and manga cafes. Any place where people exist and pass can be considered. The radio wave monitor device 1 has neither an operation unit nor an LCD display unit, and its size is as small as about half that of a mobile phone, excluding the battery unit, and can be installed anywhere inconspicuously.

FIG. 2 is a block diagram showing the internal configuration of the radio wave monitoring device 1, and is a receiving amplifier 11, a filter 12, a demodulation circuit 13, an ID memory 14, a communication control circuit 15, an LTE communication circuit 16, and a bluetooth wireless communication circuit (hereinafter, BT wireless circuit) 17, overall control circuit 18, battery 19, battery level detection circuit 20, clock 21, timer 22, suspicious person memory 23, comparison judgment circuit 24, monitor ID 25.

The LTE communication circuit 16 is a circuit for communicating with the public wireless communication network 5, and does not necessarily have to be LTE, and will be a 5G communication circuit in the future, but will be described here as LTE.

The power supply of the radio wave monitoring device 1 is described here as battery-powered in order to increase the degree of freedom of installation, but it is better to use a commercial power supply in a place where a commercial power supply can be used. In this case, the battery 19 and the battery level detection circuit 20 of FIG. 2 are unnecessary, and instead, although not shown, a power terminal connector for supplying power from a commercial power source to the radio wave monitoring device 1 via an AC adapter is provided. Provided.

For example, four AA batteries are used, but the size of the radio wave monitoring device 1 is smaller than four batteries, and together with the batteries, it is as if it were an accessory of the batteries in the battery case of the batteries. It can be installed in any shape. Although not shown, a method such as turning on the LED for 10 seconds immediately after mounting may be adopted to indicate that the radio wave monitoring device 1 is correctly mounted in the battery case and the energization is started.

The receiving amplifier 11 amplifies the radio waves emitted from the mobile phone, and together with the filter 12, the sensitivity of the receiving amplifier 11 and the characteristics of the filter 12 are selected by the instruction of the overall control circuit 18. The demodulation circuit 13 restores the mobile ID, BTID, and WiFi ID codes described above. The operations of the receiving amplifier 11, the filter 12, and the demodulation circuit 13 are cyclically switched and selected according to the three mobile IDs, BTIDs, and WiFi IDs.

There are three types of wireless communication methods for receiving and demodulating in the present invention as shown in Table 1, but the radio wave output of each is different. Since the present invention monitors the radio waves of a person's mobile phone close to a distance of about 10 m, the sensitivity of the receiving amplifier 11 when receiving the BT radio wave, the mobile phone radio wave, and the WiFi radio wave is about 10 meters, respectively. Must be set to. Further, since the frequency of the mobile phone is 0.8 to 2.1 GHz and the frequency of BT and WiFi is 2.4 to 5.6 GHz, it is desirable to change the pass bandwidth of the filter 12 between the mobile phone, BT, and WiFi. Further, the demodulation circuit 13 needs to be a demodulation method corresponding to three types of modulation methods of mobile phone, BT, and WiFi. Therefore, the overall control circuit 18 cyclically instructs the receiving amplifier 11, the filter 12, and the demodulation circuit 13 whether the ID code to be restored is a mobile phone, BT, or WiFi, and makes the restoration ability comparable. You need to keep it.

The cyclic switching timing is determined by the output of the timer 22 (in Table 3 described later, this timer value is used as the ID cyclic timer value), and is a number such as an interval of 10 seconds. In this case, the IDs of the mobile phone, BT, and WiFi are detected every 30 seconds, but the timing at which the ID code is generated from the mobile phone is controlled by the mobile phone itself or the base station, and the timer 22 It is not synchronized with the output timing of. Therefore, the ID code is not always detected at the switching timing every 30 seconds. Therefore, the management server 4 can change the setting of the ID circulation timer value depending on the restoration status of the ID code.

The received / decrypted ID code and the received date / time are stored in the ID memory 14, and the information stored in the ID memory 14 is delivered to the management server at a predetermined time interval set in the timer 22. Table 2 shows the pattern of the ID information stored in the ID memory 14 in a tabular format.

In Table 2, the date and time are managed up to the unit of year, month, day, hour, minute, and second, and the date and time when the ID code can be received is numerically entered as YMNHMS in the "date and time" column. The restored ID code is entered in the "ID" column. The ID in Table 2 is typically entered with a number such as 123, but the actual number is 28: 6A: BA: 46. It is a number like: B8: 8A. No means that it could not be detected.

In Table 2, there are three levels of "suspicious level", A, B, and C, but the default is C, and C is automatically written when the detected ID is written to the ID memory 14. Suspicious person level C is family, relatives, and friends. Generally, people who visit homes include relatives and friends, as well as postal delivery, courier delivery, newspaper delivery, etc., but when it can be estimated from the date and time information, the suspicious person level of those people is B. I will leave it as. At that date and time, if the doorphone does not ring and no one is coming, but the ID is detected, the suspicious person level is set to A.

This suspicious person level is set by the monitor control device 3 described later, but in a house, the suspicious person level will be set while remembering the person who visited at that time together with the date and time information. Initially, the default C is automatically written, but you can change the setting to B or A by the method described later. Whether or not to change this setting is at the discretion of the resident of the house, but when he / she feels that "a suspicious person seems to be there", it is desirable to change the setting with the suspicious person level as A. will do.

The management server 4 is installed in a house in a certain residential area in order to call attention to each household when the suspicious person level is judged to be A by a plurality of households in a certain residential area for the same ID. The ID code is transmitted to all of the radio wave monitoring devices 1 as a list of suspicious person level A. This suspicious person list is stored in the memory of the suspicious person memory 23 in the radio wave monitoring device 1, and thereafter, the radio wave monitoring device 1 compares the detected ID list stored in the ID memory 14 with the comparison determination circuit 24. However, when a match is found, it is immediately notified to the management server 4 and also to the BT radio circuit 17, so that an alarm is issued from the speaker (not shown) connected by the BT radio. To. At home, the alarm method will be an announcement such as "Please check outside." In addition, the radio wave monitoring device 1 installed in the parking lot estimates the ID that seems to be the criminal from the ID list detected when the vehicle vandalism actually occurs, and uses that ID as the ID of the neighborhood where the vehicle vandalism occurred. It is transmitted as a suspicious person list to all the radio wave monitoring devices 1 installed in the parking lot. Although the warning in this case matches the above-mentioned list of suspicious persons in the present invention, it cannot be determined to be the criminal without the cooperation of the police, so it is a warning message. For example, even if it is determined that the person is the criminal of the car vandalism, the message "Please be careful about the car vandalism" will be effective in deterring the crime.

Not limited to on-board vandalism, when the police can identify the criminal's ID after a crime has occurred, the management server 4 sets the ID to level X and sends it to the radio wave monitoring device 1. The radio wave monitoring device 1 registers the information in the suspicious person memory 23, and when it detects an ID code that matches the suspicious person list, it immediately notifies the management server of the information.

The information of the ID memory 14 shown in Table 2 is transmitted to the management server 4 at regular time intervals such as half a day or one day in a house and 30 minutes in a parking lot. This time interval is set in the timer 22 as a memory up timer value. The memory up timer value is managed, set, and transmitted together with the above-mentioned patrol ID timer value while monitoring the status on the management server 4 based on the crime occurrence status, the appearance information of the suspicious person, and the like.

The signal that the radio wave monitoring device 1 communicates with the management server 4 is created by the communication control circuit 15 and reaches the management server 4 via the public wireless communication network 5 by the LTE communication circuit 16. Accurate date and time information is sent from the management server 4 each time communication with the management server 4, and the clock 21 is updated to an accurate time each time. The date and time indicated by the clock 21 built in the radio wave monitor device 1 differs for each radio wave monitor device 1 depending on the accuracy of the built-in clock element, and the detected ID and date and time information are transmitted to the management server 4 based on the clock information. Even if this is done, the management server 4 cannot correctly and centrally manage the date and time information of the information of a large number of radio wave monitoring devices 1. Therefore, it is necessary to centrally manage the date and time owned by the management server 4, and for this purpose, the clock of the radio wave monitoring device 1 is set to match the clock of the management server 4.

The battery remaining amount detection circuit 20 constantly detects the remaining battery level, and sends the battery remaining amount value to the management server 4 each time the communication with the management server is performed. The management server 4 manages the remaining battery level of all the installed radio wave monitoring devices 1, and contacts the owner of the radio wave monitoring device 1 whose remaining battery level is low by e-mail, telephone, or the like. Communicate this by means and encourage battery replacement. When the radio wave monitoring device 1 is driven by a commercial power source instead of the battery, the remaining battery value is always transmitted at 100%, or a code indicating the use of the commercial power source is set and the code is transmitted.

A unique ID code (hereinafter referred to as a monitor ID) is assigned to the radio wave monitor device 1, which is issued by the management server 4 at the time of installation and written from the monitor control device 3 to the monitor ID 25 via the BT wireless circuit 17. The monitor ID 25 has a code configuration having a region in which the ID code has a meaning. As the code area, the first two digits are the installation points of private houses, parking lots, hotels, restaurants, station ticket gates, streets, streets (streets are streets such as residential areas and parks, streets are people The point classification indicates whether it is a gathering entertainment area, the next 7 digits are the address classification (the classification such as the zip code), then the installation date, the serial number, and so on.

This is because the management server 4 manages a large number of radio wave monitoring devices 1 and facilitates the search at that time. For example, when a house is damaged by a burglary, there is a high possibility that similar damage will occur in the vicinity of the house, and the management server 4 uses the ID code detected on the date and time of the damage in the vicinity of the house. Contact your home as Suspicious Person List A. At this time, the monitor ID searched based on the above-mentioned point division and address division of the monitor ID is contacted. In general, the ID of an electronic device such as a monitor ID is often written at the time of shipment at the manufacturing factory of the electronic device, but it is better to write the meaningful monitor ID when installing the monitor ID as in the present invention. When information is transmitted to a large number of radio wave monitor devices 1 selected from the management server 4, it can be said that it is more suitable from the viewpoint of big data processing.

Table 3 shows a list of signals communicated between the management server 4 and the radio wave monitoring device 1. In Table 3, transmission and reception are terms from the standpoint of the radio wave monitoring device 1.

FIG. 3 shows a block diagram of the monitor control device 3 connected to the radio wave monitor device 1 by Bluetooth radio, and shows a BT radio circuit 17, an LTE communication circuit 16, a communication signal circuit 31, a GPS sensor 32, and an ID editing memory 33. , Operation / input circuit 34, display circuit 35, installation software 36, and editing software 37. Since the mobile phone has all of these configurations, the monitor control device 3 is a mobile phone in practical use.

The functions of the monitor control device 3 are to assign a unique ID code to the radio wave monitor device 1 acquired from the management server 4 as an installation registration matter when the radio wave monitor device 1 is installed, GPS information at the installation point, and address classification. -Report the location classification to the management server 4. While looking at the ID code information group of the ID memory 14 in the radio wave monitor device 1, enter the suspicious person level in Table 2, register it in the suspicious person list, and then when it is found that it is not a suspicious person or the level of the suspicious person. When you want to change the level, change the level. Since the operation for realizing these functions is the same as the operation of a well-known mobile phone, the flow chart and the operation buttons are not shown in the following operation explanations.

Next, the operation at the time of installation will be described.

First, the owner of the radio wave monitoring device 1 has an address classification (postal code or an address classification set by the management server 4 and made selectable) and a location classification (individual residence, parking lot, hotel, restaurant, etc.). Enter the station ticket gate, streets, streets, etc.), administrator name, contact information (mobile phone number and zip code), and password from the operation / input circuit 34. After that, when the installation button (not shown) is pressed, the LTE communication circuit 16 transmits the address classification, the point name, the contact information and the output signal of the GPS sensor 32 to the management server 4, and the monitor ID is transmitted from the management server 4. Receive the code. The received monitor ID code is transmitted to the radio wave monitoring device 1 via the BT radio circuit 17 and written in the monitor ID circuit 25. As a result, the management server 4 registers the address classification, the point classification, the administrator name, the contact information, the GPS value, and the monitor ID of all the installed radio wave monitor devices 1.

Next, the information editing operation of the ID memory 14 will be described.

Press the ID information edit button (not shown), enter the password and the date and time you want to operate the information (either date or time zone), and then press the start button. The monitor ID and password will be entered in the LTE communication circuit. It reaches the management server 4 from 16. The management server 4 sends an ID list of the designated date and time to the monitor control device 3 based on the monitor ID information, and the display circuit 35 of the monitor control device 3 displays the list as shown in Table 2. While looking at the display circuit 35, the operator inputs A and B as the suspicious person level for the ID to be edited. When the editing is completed, the editing end button (not shown) is pressed, and the edited information is sent from the LTE communication circuit 16 to the management server 4, and the management server 4 rewrites the information.

As described above, the monitor control device 3 contains two built-in operation software (installation software and editing software), and the management server 4 possesses these software as application software. Then, the owner of the radio wave monitoring device 1 downloads it from the management server 4 like a mobile phone and uses it.

Table 4 shows a list of communication signals of the monitor control device 3. In Table 4, the BT wireless circuit and the LTE communication circuit are communication partners, IN is an input signal to the monitor control device 3, and OUT is an output signal.

The "address classification, etc." shown in Table 4 is the address classification and location classification (individual housing, parking lot, hotel, restaurant, station ticket gate, street, city, etc.) of the installation point, the manager's name, and contact. Destination information (mobile phone number and email address), password. From monitor control device 3 in Table 4. The signal sent to the radio wave monitor device 1 via the BT wireless circuit 17 is a monitor ID signal, which is a signal unrelated to the management server 4, and is based on the signal format of FIG. 4, the monitor ID, the remaining battery value, and the date and time. Information can be omitted.

FIG. 4 shows a signal format between the management server 4 and the radio wave monitoring device 1, and the management server 4 and the monitor control device 3. Monitor ID information and battery level value are included in all transmission signals, date and time information is included in all reception signals, and monitor ID information is included with the meaning of confirming which radio wave monitor device 1 is transmitting. The signal type indicates which communication signal is shown in Tables 3 and 4. The "monitor ID setting" signal in Table 4 does not include the monitor ID, the battery level, and the date and time information in the format shown in FIG.

The management server 4 manages the remaining battery value in addition to the monitor ID, GPS value, information such as address classification / contact information, and ID list information of all the installed radio wave monitoring devices 1, and the remaining battery value. Contact the owner of the radio wave monitoring device 1 when the remaining value falls below a certain value such as 10% or less. As a means of contact, it would be better to automatically contact by e-mail address when the remaining amount is low. When the battery is replaced, the remaining battery value is received at a value close to 100%, but if the battery is not replaced even one week after the contact, a telephone call is made.

Table 5 shows a list of the information described so far for the radio wave monitoring device 1 managed by the management server 4. In Table 5, the monitor IDs are illustrated as 1, 2, 3, ... N, but in reality, as described above, the ID information is meaningful from the point classification, the address classification, and the like.

Next, we will show what to do when a crime occurs.

When a burglary enters a private home, the burglary should stay in the house for at least 5 minutes, and the courier who visits the house spends at most 1 minute to press the door chime and wait for a reaction. The same ID should be detected several times in 5 minutes, and the mobile ID should be detected, and it is fully estimated that the owner of this ID is the criminal. By submitting this information to the police, the police will determine the owner's information with the cooperation of the mobile operator. If the mobile ID is not detected and the BTID or WiFi ID is detected, with the cooperation of the manufacturer, identify the manufacturer and the manufacturer's serial number that writes the ID on the mobile phone, and the manufacturer will use the serial number. , Since it is known which mobile phone company the product was delivered to, with the cooperation of the mobile phone company, identify the owner of the mobile phone. If the owner can be identified, this ID is registered as X level with suspicious person level A or higher on the management server 4, and the X level ID is transmitted to all installed radio wave monitoring devices 1 and suspicious. It is registered in the person memory 23. As described above, the radio wave monitoring device 1 that has received the X-level ID immediately transmits the reception to the management server 4, and the management server 4 takes action to arrest the criminal by contacting the police. The radio wave monitoring device 1 that has detected the ID of the suspicious person level X transmits it to the management server 4, but at the same time, it is also possible to transmit it to the server managed and operated by the police with the consent of the police.

The same is true for those who have been victims of molestation or assault injuries. By identifying the radio wave monitoring device 1 installed on the street or the like near the place where the molester / assault injury was damaged, the ID of the criminal who committed the molester / assault injury can be sufficiently estimated.

Further, by installing the radio wave monitoring device 1 on the train car, it is possible to detect that a molester or a pickpocket addict is on board. In this case, the police officer who arrests the criminal for the current offense immediately notifies the mobile phone owned by the police officer from the management server 4 when the suspicious person level X is detected by the radio wave monitoring device 1 (mobile phone). It is necessary to install emergency response application software that receives the contact and informs the owner), and when a police officer owns a radio wave monitor device 1 and detects a suspicious person X, it immediately responds to the police officer's mobile phone. There may be a way for the mobile phone to receive the notification and display it (again, the mobile phone needs the built-in emergency response application software mentioned above).

The same applies to arson. In the case of arson, the radio wave monitoring device 1 may also be burnt, but the ID detected at the time of arson may have already been transmitted to the management server 4, and there are multiple arsonists in close proximity. Since there is a tendency to set fire to the houses in Japan, it is possible to provide useful information for identifying the criminal.

By these methods, the person who is determined to be the criminal or the person who is wanted is set to the suspicious person level X, and all the installed radio wave monitoring devices 1 automatically try to find the ID. However, the priority of contacting the ID of the suspicious person X to the radio wave monitor device 1 is the hotel, the ticket gate of the station, the city, the street (especially the street with less traffic), the restaurant, the house (the house is also a meaning "street". ").

When a crime does not occur and the police cannot cooperate, the suspicious person cannot be identified, but the suspicious person can be estimated by the method described so far, and when the suspicious person is detected. It is possible to prevent crimes, such as paying attention to one's own actions.

The radio wave monitoring device of the present invention is small and lightweight, easy to install, and it is easy to make it invisible. It is also personally owned and easy to carry in your pocket or purse. By installing it in private houses, parking lots, hotels, restaurants, in the city or on the street, it will be a powerful tool for police to identify the criminal when a crime occurs, and it will also be effective in crime prevention, and many Is expected to be used (demand), and its industrial applicability is great.
