Description

  The present invention relates to a system for generating position information of a moving object such as a person or an object using probe information, and in particular, by using a portable terminal capable of position estimation by communication with a base station as a probe terminal. The present invention relates to a probe information generation device that generates congestion information (for example, traffic congestion information in the traffic field).

  Taking a car as an example of a moving body, not only map information but also road congestion information of a planned route is required to calculate the shortest route from the current location to the destination using the car navigation system. is there. In order to generate road traffic information, it is necessary to monitor the movement of a car traveling on the road. To calculate traffic congestion information by monitoring the movement of a vehicle, a method using a road information communication system (VICS) and a probe equipped with a GPS (Global Positioning System) receiver There is a method of calculating by probe information aggregated from a car.

  In order to calculate traffic congestion information using VICS, roadside sensors are installed on roads nationwide, and the speed and movement / stop status of automobiles obtained by the roadside sensors are collected as data in the VICS center, and the data is accumulated. Need to generate traffic information. However, in order to obtain traffic jam information by VICS, it is necessary to install a large number of roadside sensors on national roads (national roads, highways, prefectural roads, etc.), which requires a huge investment, and therefore requires capital investment. was there. In addition, in order to generate traffic jam information with a probe car equipped with a GPS receiver, it is necessary to secure the number of probe cars actually traveling on the road and to transmit communication information from the probe car to the center. There are various problems in generating traffic jam information throughout the country, which has been a problem in the spread.

Therefore, conventionally, a traffic situation estimation method and a traffic situation estimation / provision system using probe information that uses a probe car to realize traffic jam situation prediction / estimation in an area where the probe car is not currently running have been proposed ( For example, see Patent Document 1). In addition, for people, conventionally, location information is required to calculate the degree of congestion of people, but mobile phone base station information is used as a representative method for positioning the owner of a mobile phone. Base station positioning method and mobile phone positioning method equipped with a GPS function. In addition, as a method of not using a cellular phone, a method using an RFID (Radio Frequency Identification) tag (IC (Integrated Circuit) chip, Bluetooth (registered trademark), UWB (Ultra Wide Band), etc.), a wireless LAN (Local Area Network), etc. ) It is based on positioning.
JP 2002-251698 (paragraphs 0013 to 0017, FIG. 4)

  However, according to the technique disclosed in Patent Document 1, in order to acquire probe information using a probe car, a GPS receiver is installed in a target automobile, and the GPS receiver can obtain the probe information. It is necessary to transmit the position information to the probe center using communication means such as a mobile phone, and to accumulate the collected position information at the probe center to generate traffic information. For this reason, the communication cost required to transmit the position information from the probe car to the probe center cannot be ignored. In particular, the probe information utilizing the data at the time of a mobile phone call has a problem that the communication cost becomes enormous.

  Also, when generating traffic information, when using a mobile phone during a call, voice calls while moving are prohibited by law, so the probe data collected is for vehicles equipped with hands-free equipment. There is a problem that the number of samples of probe data is limited. Furthermore, conventionally, information created from mobile phone control information (signals) and area information has been aggregated as probe data at the probe center and processed into position information of people and mobile objects. When provision is required, since it is required to process all the probe data in real time without considering the importance, there is a problem that the processing speed of the computer becomes slow.

  In addition, in the case of targeting people, conventionally, in order to calculate the degree of congestion of people, a base station positioning method for obtaining position information by utilizing base station information of a mobile phone, and positioning by a GPS mobile phone The method is a typical method. Here, in the former method, base station information is used, so there is a problem that the accuracy does not reach the required accuracy, and in the latter method, the communication cost required for transmitting location information from the terminal to the center becomes a problem. It was. On the other hand, in the method using the RFID tag and the method using the wireless LAN positioning, it is necessary to give the tag and various communication devices to a target person who wants to collect, but there is a problem that they are difficult to spread.

  Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide means for generating probe information relating to a nationwide mobile body with a small capital investment.

  The present invention that solves the above problems is a probe information generation device that is capable of communicating with a mobile terminal that moves with a mobile body via a base station and a network, and that generates probe information about the mobile body through communication with the mobile terminal. The mail information is delivered to a predetermined mobile terminal, the delivery confirmation information transmitted by the predetermined mobile terminal is received for the delivered mail, and stored by the mail information transmitting / receiving unit and the mail information transmitting / receiving unit. And a probe information generation unit that generates probe information related to the moving object from position information and time information of the mobile terminal included in the delivery confirmation information. The present invention includes other probe information generation devices, probe information generation methods, and probe information generation programs.

  According to the present invention, probe information relating to a nationwide mobile unit can be generated with a small capital investment.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. In the embodiment of the present invention, in order to identify the position where the owner of the mobile terminal is located and to grasp the movement status and the crowded / spreading status, the mail sent by normal packet communication is delivered to the mobile terminal. In addition, the mail delivery confirmation information (ACK information) is returned from the portable terminal to the mail server.

<< First Embodiment >>
<System configuration and overview>
FIG. 1 is a diagram showing a configuration of a probe information generation system according to the first embodiment of the present invention. The probe information generation system 100 includes a plurality of mobile terminals 1, a plurality of base stations 2, a mail server (mail information transmission / reception unit) 3, and a position information generation device (probe information generation unit) 4. The mobile terminal 1 and the base station 2 can communicate with each other when the mobile terminal 1 is located within the communication range of the base station 2. Communication between the base station 2 and the mail server 3 and between the mail server 3 and the position information generating device 4 is possible via a wireless or wired network. Here, the probe information is information on the position and movement of a moving body such as a person or an object (for example, traffic information). The position information generating device 4 is based on one or more pieces of information (probe data) received from the mobile terminal 1. Is generated. The probe data is information that is appropriately acquired according to the position of a moving body such as a person or an object, and is individual information received from the mobile terminal 1.

  When the mobile terminal 1 receives a mail delivery from the base station 2, the mobile terminal 1 replies to the base station 2 with delivery confirmation information for notifying the fact. This operation is automatically performed regardless of the operation of the user who owns the mobile terminal 1, that is, without the user being aware of it. The delivery confirmation information includes the approximate current position (for example, latitude and longitude) of the mobile terminal 1 and the current time. In order to measure the current position, a base station positioning method based on radio field strength between the base station and the terminal using base station information of the mobile terminal, and a positioning method using a mobile terminal equipped with a GPS function can be considered. The mobile terminal 1 is realized by, for example, a mobile phone or a PDA (Personal Digital Assistant: mobile information terminal).

  Upon receiving an instruction from the mail server 3, the base station 2 transmits an email to a predetermined mobile terminal 1 within its communication range, receives the delivery confirmation information returned from the mobile terminal 1, and receives the delivery confirmation. Information is transmitted to the mail server 3. The base station 2 is realized by, for example, a mobile phone base station.

  Information relating to the mobile terminal 1 (hereinafter referred to as mobile terminal information) is registered in the mail server 3 in advance. The registered mobile terminal information includes a solid identification number (identification number), user attribute information, and the like. The solid recognition number is a number unique to the mobile terminal 1. When the mail server 3 transmits mail to the mobile terminal 1 via the base station 2, this solid recognition number is used instead of a so-called mail address. The user attribute information is information indicating the attribute of the user who owns the mobile terminal 1, and is, for example, a job type, a hobby, a preference, or the like. When the position information generating device 4 generates probe information from mail delivery confirmation information, this attribute information is used to narrow down mail delivery destinations when desired probe information is to be generated.

  Next, the mail server 3 instructs the base station 2 to transmit a mail to a predetermined mobile terminal 1 within the communication range, and accumulates delivery confirmation information received from the mobile terminal 1 by the base station 2. Then, the accumulated delivery confirmation information is transmitted to the position information generating device 4 as necessary. The mail server 3 is realized by, for example, a server computer.

  The position information generation device 4 generates probe information based on the delivery confirmation information received from the mail server 3. The probe information is, for example, traffic information related to traffic jams. The position information generation device 4 is realized by a computer such as a PC (Personal Computer) or a server, for example.

  FIG. 2 is a diagram illustrating a configuration example of the mail server. The mail server 3 includes a processing unit 31 and a storage unit 32. The processing unit 31 is realized by a CPU (Central Processing Unit) executing a program stored in a predetermined memory in order to exhibit the function of the mail server 3. The storage unit 32 stores information handled by the mail server 3 and is realized by a non-volatile storage device such as a hard disk device. The storage unit 32 stores, for example, mobile terminal information 321 and delivery confirmation information 322. As already described, the mobile terminal information 321 includes a solid recognition number related to the mobile terminal 1 and user attribute information. Further, the delivery confirmation information 322 includes current position information and time information of the mobile terminal 1.

  FIG. 3 is a diagram illustrating a configuration example of the position information generation device. The position information generation device 4 includes a processing unit 41 and a storage unit 42. The processing unit 41 is realized by the CPU executing a program stored in a predetermined memory in order to exhibit the function of the position information generating device 4. The storage unit 42 stores information handled by the position information generation device 4 and is realized by a nonvolatile storage device such as a hard disk device. The storage unit 42 includes, for example, a map information database (map information storage unit) 421 that stores map information and a road information database (road information storage unit) 422 that stores road information.

  Here, the processing unit 41 includes, for example, a moving speed calculation unit 411 and a position information generation unit 412. The movement speed calculation unit 411 acquires the movement distance and movement time of the mobile terminal 1 from the position information and time information included in the delivery confirmation information 322 stored in the mail server 3, and the mobile terminal 1 from the movement distance and movement time. The moving speed of is calculated. The position information generation unit 412 is based on the movement speed calculated by the movement speed calculation unit 411 or the difference between the movement speed and the legal speed information of the road corresponding to the position information stored in the road information database 422 in advance. Traffic information related to the position information is generated, and the traffic information is superimposed on the map information stored in the map information database 421 and output. The traffic information mentioned here is information that compares information on the traffic jam of the vehicle and the actual moving speed with the legal speed. By acquiring these information, whether or not the vehicle is being passed smoothly. It is possible to determine the difference in the flow of the vehicle according to the time zone.

<Mail server processing>
FIG. 4 is a flowchart showing a process of changing the delivery destination and delivery frequency of mail depending on the job type in the mail server. This process is intended to make the type of probe information different as an attribute of the user who owns the portable terminal 1, for example, by changing the delivery frequency depending on the job type. For example, with respect to the portable terminal 1 possessed by a user having a high job frequency such as a mail collector / delivery company, it is classified and collected mainly on the delivery confirmation information of the mail received from the portable terminal 1. Thus, it is possible to generate information useful for a moving body, such as a car or a motorcycle, which is a moving means for a user of that job type (for example, traffic information related to a living road).

  As shown in FIG. 4, the mail server 3 first extracts the mobile terminal 1 in the area of interest for which probe data is to be collected (step S401). Specifically, the mail server 3 stores a solid identification number unique to the mobile terminal 1 in advance, and grasps in which communication range of the base station 3 the mobile terminal 1 with the solid recognition number exists. ing. This is possible when the mail server 3 recognizes a handover or the like for switching the base station 3 to which the mobile terminal 1 communicates as the mobile server 1 moves through the base station 3. Therefore, the base station 3 targeted for the communication range overlapping the area of interest is identified, and the mobile terminal 1 existing within the communication range of the base station 3 is extracted. In this case, the extraction accuracy of the mobile terminal 1 existing in the area of interest may be improved by extracting the mobile terminal 1 existing in the common part of the communication range of the two or more base stations 3.

  Next, as for the attribute information of the user of the mobile terminal 1, contract data exchanged with a communication carrier (for example, a mobile phone carrier) at the time of subscription is stored in the mobile terminal information 321 of the storage unit 32 in advance. Therefore, referring to the attribute information, the mobile terminal 1 having the attribute information corresponding to the desired probe information is selected (step S402). For example, if traffic information on a living road is necessary, the portable terminal 1 possessed by a user whose occupation is a home delivery company or a postal delivery person is selected. If the traffic information on the main road is necessary, for example, the portable terminal 1 possessed by the user whose occupation is a bus or tramway driver is selected.

  Subsequently, the mail server 3 sets the mail delivery frequency N (times / t) in the storage unit 32 (step S403). In this case, when it is necessary to review the delivery frequency N due to the movement / stop state of the mobile terminal 1 (Yes in Step S404), the review is performed again (Step S403). When it is not necessary to review the delivery frequency N (No in step S404), the mail is delivered to the focused mobile terminal 1 (step S405). In this case, the mail server 3 instructs the base station 2 in the communication range in which the mobile terminal 1 exists to transmit the mail to the individual identification number of the mobile terminal 1. Then, the mail delivery confirmation information is received from the portable terminal 1 and stored in the storage unit 32 (step S406).

  Here, it is determined whether or not the number of stored data received from the portable terminal 1 is sufficient (step S407). This determination is performed by comparing the threshold value set according to the purpose of use of the delivery confirmation information, that is, the type of probe information to be generated from the delivery confirmation information. For example, when traffic information is generated as probe information, if the traffic of the vehicle is smooth, the data score may be small, so a small threshold is set. In addition, if the vehicle is congested, a large threshold is set because a large number of data points are required to investigate the situation in detail. When the number of data points is not sufficient (insufficient) (No in step S407), the process is performed again from the review of the delivery frequency N in step S403. When the data score is sufficient (Yes in step S407), the series of processes is terminated.

  In other words, the mail server 3 refers to the mail transmission / reception record (delivery confirmation information), and if the number of mails (the number of data necessary for generating probe information) is insufficient, the focused mobile terminal 1 In addition, mail delivery is repeated until the required number of data is reached.

  As a portable terminal 1 possessed by a crew member who takes a mail on the express bus, a probe representing the movement state (speed, travel time, degree of congestion, etc.) on the expressway if the mail delivery confirmation information is mainly collected. Data can be collected. Further, by collecting mainly the mail delivery confirmation information of the mobile terminal 1 possessed by the housewife among the occupations, it is possible to collect the probe data that can be processed into the movement history information of the housewife. If the occupation is a student, it is possible to collect probe data that can be processed into student movement history and information on the density at that time.

  Further, by collecting mainly the mail delivery confirmation information of the portable terminal 1 possessed by the train crew or the passenger, the train operation information can be collected. This means that people other than railway operators can generate real-time operation information, and the actual operation status at the time of the accident is collected regardless of the information from the operator holding the railway operation information. Is possible. According to this method, the operation status of the bus and the subway can be checked by collecting mainly the delivery confirmation information of the mail of the mobile terminal 1 possessed by another means of transportation, for example, the driver of the bus or the subway or the passenger. It is possible to grasp without obtaining information of each business operator. In particular, when passengers make connections or transfers, it is possible to consolidate operation information across multiple operators into one database, so special servers such as servers and probe data collection terminals that collect probe data for each operator. Operation information can be created from aggregated probe data without introducing dedicated infrastructure.

  The probe data collected as described above is processed into the movement history distribution of the moving body and the distribution characteristic information (probe information) for each time zone / area, so that the operation management of the moving body, traffic information, each time zone / area Can be used for marketing data, city planning, taxi dispatch, local advertising planning, and understanding the operation status of various means of transportation.

<< Second Embodiment >>
In the second embodiment of the present invention, the mobile terminal 1 in the area where probe data is desired to be collected is determined, and the mail delivery interval to the mobile terminal 1 is intentionally changed for delivery. When it is determined that the mobile terminal 1 is moving, the mail delivery interval is shortened (that is, the delivery frequency is increased), and when it is determined that the mobile terminal 1 is not moving, the mail delivery interval is decreased. The probe data is collected efficiently by elongating (ie, lowering the delivery frequency) and delivering mail. The configuration of the probe information generation system 100 is the same as that shown in FIGS.

  FIG. 5 is a flowchart showing a process of changing the mail delivery interval in the mail server. As shown in FIG. 5, the processing from step S501 to step S505 is the same as the processing from step S401, step S402, and step S405 described in FIG. 4, but the delivery interval is changed by the processing from step S507 to step S509. Mail can be delivered. That is, after receiving and accumulating mail delivery confirmation information from the portable terminal 1 (step S506), it is determined whether or not the accumulated data score is sufficient (step S507). About the determination method, it is the same as that of description of step S407 of FIG. If the number of data is sufficient (Yes in step S507), the series of processes is terminated. If the number of data points is not sufficient (No in step S507), the mail delivery time interval Δtn is set and reviewed (step S508). Then, by the reviewed time interval Δtn, the mail is delivered, the data is received and accumulated, and this is repeated (step S509). Thereafter, it is determined again whether or not the number of accumulated data is sufficient (step S507).

  In the present embodiment, in the process of step S508, a mail is delivered to a mobile terminal 1 of interest at a certain time, the next mail is delivered at a certain time interval, and the delivery confirmation information of both mails is used. If there is no difference in the obtained position, it is determined that the probe terminal is not useful for traffic information, and it is not delivered at the timing when the next mail is delivered, or the time interval Δt is set large and a predetermined time is left. It is intended to be delivered from. With this method, it is possible to collect movement information with high accuracy and efficiency by narrowing down the collection of probe data to an area of interest and adjusting the time interval according to the movement / stop status.

  Also, depending on the intended use of the acquired probe data (delivery confirmation information), for example, when it is desired to collect probe data over a wide range because of coarse accuracy, the mail delivery frequency is changed depending on the density of the portable terminal 1 (see FIG. By changing the mail delivery frequency in step S405 in step 4), probe data can be collected efficiently. Specifically, when the mobile terminals 1 are dense, the mail delivery frequency is lowered, and when the mobile terminals 1 are scattered, the mail delivery frequency is increased.

  According to this, when there are few portable terminals 1 compared with a wide area range, it is possible that the accuracy of the probe data which can be collected becomes rough, but even if it is so, the probe information regarding a wide area Can be generated efficiently. In addition, although different probe information may be produced | generated according to attribute information from the positional information on the portable terminal 1 in the same place, in other words, from the positional information on the portable terminal 1 in a different place, the same Probe information corresponding to the attribute information may be generated. Therefore, in order to clarify that the probe information is generated according to the predetermined attribute information, an identifier indicating that is attached to each probe information.

<< Third Embodiment >>
In the third embodiment of the present invention, the mail delivery frequency is changed by information from other sensors (for example, VICS information and roadside sensor).

  FIG. 6 is a diagram showing a configuration of a probe information generation system that selects a mail delivery destination in combination with external sensor information. As shown in FIG. 6, the probe information generation system 100 a includes a plurality of portable terminals 1, a plurality of base stations 2, a mail server 3, and a position information generation device 4, similar to the probe information generation system 100 of FIG. 1. Composed. However, in the present embodiment, in addition to the probe data from the mobile terminal 1, information is desired from information (for example, VICS traffic information, monitoring camera information, etc.) by other sensors installed on the road and other probe information. The congestion information of the area is collected and utilized to change the mail delivery frequency to the mobile terminal 1 possessed by the user in the area of interest. That is, by increasing the frequency of mail delivery for generating probe information and reducing the frequency of mail delivery to users in other areas, the mobile terminal 1 in the area to be focused on can efficiently transmit probe data. It is intended to collect.

  According to the embodiment of the present invention described above, it is possible to specify the position information of a moving object such as a person or an object by utilizing the mail delivery confirmation information mainly used in normal packet communication. In addition, when it is determined that the number of portable terminals in the area to be focused on is small and the number of probe data samples is insufficient to generate probe information, mail is actively sent to the portable terminal 1 in the area to be focused on. Since probe data is acquired by transmitting, the communication load for collecting the probe data can be suppressed, investment such as remodeling of the equipment is small, and position information of the mobile body on a nationwide scale can be generated.

  Further, according to the embodiment of the present invention, since the mail delivery confirmation function is utilized, the location information of the portable terminal 1 can be collected even in a standby state regardless of a call / non-call. It is possible to generate various probe information by suppressing communication costs and reducing communication costs.

  Although the embodiment of the present invention has been described above, the programs executed by the mail server 3 shown in FIG. 2 and the position information generating device 4 shown in FIG. 3 are recorded on a computer-readable recording medium. It is assumed that the mail server 3 and the position information generation device 4 according to the embodiment of the present invention are realized by causing a computer system to read and execute a program recorded on a recording medium. These programs may be provided to the computer system via a network such as the Internet. Further, a semiconductor chip in which a program is written may be provided.

<< Other embodiments >>
An example of the preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment, and can be appropriately changed without departing from the spirit of the present invention. For example, the following embodiments can be considered.
(1) In the above embodiment, the mail server 3 and the position information generation device 4 are described as separate computers. However, the functions of the mail server 3 and the position information generation device 4 are combined into one computer (probe information generation). Apparatus) may be realized collectively.
(2) In the above-described embodiment, the mail server 3 actively collects the location information included in the delivery confirmation information by actively delivering the mail to the predetermined mobile terminal 1. It is also possible to use the mail delivery confirmation information. In other words, the delivery confirmation function that is provided in the general mail (mail that is sent and received without intending to generate probe information) function that is normally sent and received by the user who has the mobile terminal 1 such as a mobile phone is utilized. By doing so, it is possible to generate probe information.
(3) In the above embodiment, as shown in the flowchart of FIG. 4, the mobile terminal 1 in the area of interest is extracted, selected according to attribute information, and mail is delivered to the selected mobile terminal 1. However, a delivery destination list may be created and mail may be delivered based on the delivery destination list. That is, the mail server 3 first extracts all the mobile terminals 1 within the communication range of the base station 3 within a predetermined range including the area of interest, and creates a delivery destination list that lists those mobile terminals 1. Next, mails are delivered to the portable terminals 1 listed in the delivery destination list one by one in order, and the delivery confirmation information is received and accumulated. When the mail is delivered to all the mobile terminals 1 in the delivery destination list, it is confirmed whether or not the received delivery confirmation information is sufficient. This is because delivery confirmation information may not be received even if mail is delivered based on a sufficient delivery destination list. If the delivery confirmation information is not sufficient, the e-mail is delivered again to the portable terminal 1 for which the delivery confirmation information could not be received, or a new portable terminal 1 is added to the delivery destination list, and the e-mail is sent to the added portable terminal 1. Perform processing such as delivery.
