Description

  The present invention relates to a probe information center and a transmission apparatus that transmits data to the probe information center.

Conventionally, traveling state information (hereinafter referred to as probe information) of a mounting destination vehicle is transmitted to a probe information center from a plurality of probe devices respectively mounted on a plurality of vehicles, and the probe information is transmitted to the probe information center. A technique of a probe information collection system is known that is processed into distribution data, and the created distribution data is distributed from a probe information center to a communication device (see, for example, Patent Document 1). As a method for putting this technology into practical use, it is considered that a probe device is mounted on a vehicle used in an existing dispatch system such as a taxi or a bus.
JP 2006-238776 A

  However, since the business forms of the vehicle on the probe information transmission side are various, variations occur between the contents of the probe data transmitted from each vehicle. Therefore, the information required by the probe information center is often not efficiently provided to the probe center.

  The present invention has been made in view of the above points, and an object of the probe information collection system is to enable a probe information center to efficiently acquire necessary information.

  In order to achieve the above object, the first feature of the present invention is that it receives information on the driving situation of a mounting destination vehicle detected by a plurality of probe devices mounted on different vehicles, and receives the information on the received driving situation. This is for a probe information center that distributes processing information obtained as a result of processing to a plurality of communication devices. The probe information center identifies the quality of the driving situation information transmitted in a state associated with the provider identification information indicating the provider of the information among the received driving situation information, and includes the provider identification information. The corresponding provider is processed to provide higher consideration as the identified quality is higher.

  In this way, the higher the quality of the traveling state information transmitted to the probe information center in the first quality index, the higher the consideration for the provider. As a result, an incentive to provide the information provider with information highly evaluated by the first quality index of the probe information center works, and as a result, the probe information center can efficiently acquire necessary information. Become.

  Here, the information on the traveling state refers to information on one or both of the external environment (for example, gradient) during traveling and the vehicle behavior (for example, power consumption, vehicle speed) during traveling. In addition, the vehicle travel status information may be transmitted from the probe device to the probe information center via wireless communication or the like, or a person records the vehicle travel status information from the probe device. When the storage medium is unloaded and the storage medium is connected to another communication apparatus, the communication medium may be transmitted from the communication apparatus to the probe information center via wireless communication or the like. That is, the probe information center only needs to finally receive information on the traveling state of the vehicle detected by the probe device, and any reception path may be used.

  The “predetermined” here means “predetermined”. The term “in advance” means that the predetermined quality index is not actually used. Therefore, the predetermined time may be at the time of manufacturing the probe information center, or may be just before the quality index is used. Further, “consideration” does not mean only monetary consideration but may be high added value of data to be distributed.

  In addition, as “a process for providing higher value to the provider corresponding to the provider identification information as the specified quality is higher”, specifically, the process is delivered to the communication device corresponding to the provider identification information. The processing information is determined such that the higher the specified quality is, the higher the quality is based on a predetermined second quality index of the processing information, and the processing information thus determined is a communication device corresponding to the provider identification information. It may be a process of delivering to. In this way, the provider of the travel status information can receive higher quality processed data as the quality of the provided information is higher in light of the first quality index. .

  In addition, the probe information center, as the first quality index, increases as the total data amount or the data reception frequency increases with respect to all travel status information having the same provider identification information received within the past reference time range. An indicator of quality may be used.

  In this way, when a certain provider has a large number of vehicles equipped with probe devices, if the same provider identification information is associated with the information on the driving situation detected by the probe devices, In the probe information center, the amount and frequency of travel situation information received from the provider is increased compared to other providers. Therefore, so-called large providers are favored.

  In addition, according to a second feature of the present invention, the transmission device acquires information on a traveling state of a mounting destination vehicle detected by a plurality of probe devices mounted on different vehicles, and the acquired information on the traveling state is acquired. The same provider identification information is associated with each other, and the information on the traveling status as a result of the association is transmitted to the probe information center that employs the first quality index as described above.

  In this way, the association of the provider identification information of the large provider having a plurality of vehicles on which the device is mounted with the vehicle status information is not individually performed by the probe device, It is performed in a lump in the transmission device. Therefore, it is not necessary for each probe apparatus to have provider identification information.

  Hereinafter, an embodiment of the present invention will be described. FIG. 1 schematically shows an example of a probe information collection system according to this embodiment. In the probe information collection system, the probe devices 2, 7, 9 mounted on the vehicles 1, 6, 8 respectively detect the probe information of the mounted vehicles and finally probe the detected probe information. The information center 5 receives it.

  Here, the probe information of the vehicle refers to information on the traveling state of the vehicle. The information on the traveling state refers to information on either or both of the external environment during traveling and the vehicle behavior during traveling. Examples of the vehicle travel status information include location information of the vehicle, travel speed information, road surface gradient information, and information on the time at which these probe information is acquired. Each probe device 2, 7, and 9 detects such information using various sensors (for example, a GPS receiver, a vehicle speed sensor, an inclination sensor, etc.) mounted in the vehicle. Further, when the map matching process widely used in the car navigation system or the like can be performed, the probe devices 2, 7, and 9 may detect the position of the map matching result as the location of the own vehicle. The probe information includes information indicating whether map matching is used for detecting the location.

  Probe information detected by the probe device 2 mounted on the vehicle 1, which is an individual vehicle, is transmitted to the probe information center 5 via the wireless communication path from the probe device 2 to the mobile phone network 3 and the communication network 4. The The communication network 4 may be a wide area network such as the Internet or a dedicated line only for providing probe information.

  Further, probe information detected by the probe devices 7 and 9 mounted on the supplier vehicles 6 and 8 owned by the same supplier is transferred from the probe devices 7 and 9 to the supplier information center 10. The trader information center 10 transmits the received probe information to the probe information center 5 via the communication network 4. The provision of probe information from the probe devices 7 and 9 to the vendor information center 10 may be realized by wireless communication as shown in FIG. 1 or probe information is recorded from the probe devices 7 and 9. The storage medium may be realized by a person carrying the storage medium to the vendor information center 10 and connecting the storage medium to the vendor information center 10.

  Here, a transmission form of probe information transmitted from the probe devices 2, 7, and 9 by radio will be described. The probe devices 2, 7, and 9 transmit probe information detected in the time interval as a set of probe data frames every predetermined time interval (for example, a time interval of 1 minute in length). Then, one piece of information about the detection time and the position of the host vehicle at the time of detection is added to the probe data frame. The probe device 2 mounted on the personal vehicle 1 adds the provider identification information of the owner of the personal vehicle 1 to the probe data frame. This provider identification information is registered in the probe device 2 in advance. Therefore, data transmitted wirelessly from the probe devices 2, 7, and 9 basically has real-time properties.

  However, since the probe data frame cannot be transmitted while the vehicle is traveling in a position where wireless communication is not possible, such as underground or in a tunnel, the probe data frame during that period is transmitted after the wireless communication is recovered. . The probe data frame in such a case may not have real-time characteristics.

  The probe information in the storage medium carried from the probe devices 7 and 9 mounted on the supplier vehicles 6 and 8 to the supplier information center 10 will be described. The probe information in the storage medium is a collection of information detected multiple times within a period longer than the data to be wirelessly transmitted, such as one day, half a day, several days, etc. Information of the detection time and detection position is added.

  The probe information center 5 processes the probe data by performing statistical processing or the like on the probe information from the vehicles 2, 5, 7 received in this way, and provides information on the processing result as the probe device. 2. Distribute to the supplier information center 10 and other communication devices. At the time of distribution, based on the quality of the probe information provided in the past from the distribution destination, what kind of quality processing information is to be transmitted to the distribution destination is determined.

  FIG. 2 schematically shows the configuration of the supplier information center 10. The supplier information center 10 includes a wireless unit 11, a network I / F unit 12, an external data reading unit 13, a real-time data storage unit 14, a past data storage unit 15, and a control unit 16.

  The wireless unit 11 is a device that receives probe information by wirelessly communicating with the dealer vehicles 6 and 8. The network I / F unit 12 is an interface for connecting to the communication network 4 and realizing data exchange with the probe information center 5. The external data reading unit 13 is a device that reads the probe information from a storage medium in which the probe information detected by the probe device is recorded. The real-time data storage unit 14 is a device having a storage medium for storing real-time information as probe information received by the radio unit 11 as real-time data. The past data storage unit 15 is an apparatus having a storage medium for storing, as past data, information having no real time property among probe information received by the wireless unit 11 and probe information read by the external data reading unit 13. is there.

  The control unit 16 is a device that controls the operations of these units 11 to 15. Specifically, the control unit 16 determines whether or not each of the probe data frames received by the wireless unit 11 has real-time characteristics. If there is real-time characteristics, the control unit 16 sends the probe data frames to the real-time data storage unit 14. If there is no real-time property, the probe data frame is stored in the past data storage unit 15. When it is determined that there is real-time property, the detection time information of the probe information included in the probe data frame indicates a past less than a reference time width (for example, 5 minutes, 10 minutes) from the present time. It is. Further, when it is determined that there is no real-time property, when the probe information detection time information included in the probe data frame indicates a past of a reference time width (for example, 5 minutes, 10 minutes) or more from the present time It is.

  Also, the control unit 16 moves the probe data frame recorded in the real-time data storage unit 14 whose real-time property is lost due to the passage of time to the past data storage unit 15 as past data. Let

  The control unit 16 transmits the probe data frame in the real-time data storage unit 14 to the probe information center 5 as soon as it is recorded in the real-time data storage unit 14 (for example, within 10 seconds). . In addition, the control unit 16 collects past data acquired from the previous timing to the current timing at a predetermined timing (for example, timing of one hour interval) for past data in the past data storage unit 15. It transmits to the probe information center 5 as a probe data frame.

  Further, when transmitting the probe data frame, the control unit 16 adds the same provider identification information to each probe data frame regardless of which vehicle's probe device has detected the probe data frame. Then, the data is transmitted to the probe information center 5 using the network I / F unit 12. The provider identification information added here is provider identification information that is assigned in advance to the contractor having the contractor information center 10 at the time of contract.

  Note that the probe devices 2 and 7, the supplier information center 10, and other communication devices may transmit a distribution request to the probe information center 5 based on a user operation.

  FIG. 3 schematically shows the configuration of the probe information center 5. The probe information center 5 includes a network I / F unit 52, an individual data storage unit 53, a real-time data storage unit 54, a past data storage unit 55, a real-time traffic jam information processing unit 56, a statistical traffic jam information processing unit 57, and distribution traffic jam information distribution. Unit 58, real-time data transmission unit 59, statistical data transmission unit 60, and control unit 61.

  The network I / F unit 52 is an interface for connecting to the communication network 4 and realizing data exchange with the supplier information center 10. The individual data storage unit 53 is a device having a storage medium for temporarily recording probe information received via the network I / F unit 52. The real-time data storage unit 54 is a device having a storage medium for storing real-time data among the data stored in the individual data storage unit 53 as real-time data. The past data storage unit 55 is a device having a storage medium for storing non-real time data among past data stored in the individual data storage unit 53 as past data.

  The real-time traffic jam information processing unit 56 is a device that generates traffic jam information with prompt information by processing the real-time data in the real-time data storage unit 54. The statistical traffic jam information processing unit 57 is a device that generates statistical traffic jam information indicating past traffic jam statistics by processing past data in the past data storage unit 55.

  The distribution traffic information distribution unit 58 outputs information that needs to be distributed among the information generated by the real-time traffic information processing unit 56 to the real-time data transmission unit 59, and is also generated by the statistical traffic information processing unit 57. Among the received information, information that needs to be distributed is output to the statistical data transmission unit 60. Whether or not it is necessary to distribute is determined for a limited distribution target (for example, limited to a specific area) from the probe device 2, 7, 9 or another communication device via the network I / F unit 52. Is determined based on the limited content.

  The real-time data transmission unit 59 distributes the real-time data received from the distribution congestion information distribution unit 58 to the transmission source of the distribution request using the network I / F unit 52. The statistical data transmission unit 60 distributes the past data received from the distribution congestion information distribution unit 58 to the transmission source of the distribution request using the network I / F unit 52. The real-time data transmission unit 59 and the statistical data transmission unit 60 determine which communication device the data received from the distribution congestion information distribution unit 58 is transmitted to, as will be described later, the transmission destination registered by the control unit 61 Determine according to the data.

  The control unit 61 controls each unit 52 to 60 of the probe information center 5. Specifically, the control unit 61 repeatedly executes the probe information reception process 100 shown in FIG. 4 and the information provision process 200 shown in FIG. 5 as necessary.

  Specifically, the control unit 61 does not execute the probe information reception process 100 and starts executing the probe information reception process 100 based on the fact that the network I / F unit 52 has received the probe data frame. To do. Then, in one execution of the probe information reception process 100, the current time is compared with the detection time in the received probe data frame, so that the delay of the current time with respect to the detection time is within an allowable range (for example, 5 minutes, 10 (Step 110), and if it is less than the allowable width, a real-time flag (hereinafter referred to as R flag) in the probe data frame is set to ON (step 115).

  FIG. 6 schematically shows the data format of the probe data frame 70. As shown in this figure, a probe data frame 70 transmitted from the probe device 2, the supplier information center 10 and the like and received by the probe information center 5 includes a provider identification information section 71, a probe information section 72, an R flag section 73, An M flag unit 74, a T flag unit 75, and a D flag unit 76 are provided. The provider identification information part 71 is a part in which provider identification information is recorded. The probe information part 72 is a part in which detected information (detection time, vehicle speed, gradient, etc.) is recorded. The R flag unit 73, the M flag unit 74, the T flag unit 75, and the D flag unit 76 are respectively an R flag, a map matching flag (hereinafter referred to as M flag), a collection frequency flag (hereinafter referred to as T flag), and a data amount. This is a part for recording a flag (hereinafter referred to as D flag). At the time when the probe data frame 70 is transmitted from the probe device 2 and the supplier information center 10, the values of the R flag unit 73, the M flag unit 74, the T flag unit 75, and the D flag unit 76 are off. .

  Subsequently, the control unit 61 determines whether or not the location information of the probe data frame 70 has been subjected to map matching based on information in the probe information unit 72 (step 120), and performs map matching. If so, the M flag is set on (step 125).

  Subsequently, the probe data frame 70 is recorded in the individual data storage unit 53 (step 130). Thereafter, until the reference time (for example, 10 minutes) elapses after the start of this probe information reception process 100 (step 140), the reception of another probe data frame is awaited (step 135). Then, the same processing as the previously received probe data frame is performed on the received probe data frame (steps 110 to 130).

  After the reference time elapses, the control unit 61 groups the probe data frames recorded in the individual data storage unit 53 after the start of the current probe information reception processing 100 based on the provider identification information (step 145). For each group, it is determined whether or not the number of probe data frames exceeds a reference number (eg, 1, 2, 5) (step 150). (Step 155). Further, for each group, it is determined whether or not the total data amount of all the probe data frames exceeds the reference amount (step 160), and if it exceeds, the D flag is set on (step 165).

  As described above, since the collection frequency and the amount of received data are measured and determined collectively for each provider identification information, a provider in which many probe devices are associated with one provider identification information, that is, a large provision The measurement result is likely to be larger and the T flag and the D flag are more likely to be turned on than the individual provider who assigns one probe device to one provider identification information. .

  When the control unit 61 executes the processing 100 as described above, the probe information center 5 determines whether or not the time of the received probe data frame has real-time characteristics (see step 110), and map matching. Is determined (see step 120), and the determination result is added as a flag to the probe data frame (see steps 115 and 125). Then, the probe data frames acquired within the reference time range (see steps 135 and 140) are divided by provider identification information, and whether or not the collection frequency of probe data frames is higher than the reference for each provider identification information (steps) 150) and whether or not the total received data amount of the probe data frame is larger than the reference (see step 160), and the determination result is added as a flag to the probe data frame having the provider identification information. (See steps 155 and 165). As a result, the individual data storage unit 53 is in a state where a plurality of probe data frames having different flag values for each provider identification information are stored as shown in FIG.

  Further, the control unit 61 starts executing the information providing process 200 immediately after the execution of the probe information receiving process 100. First, the probe data frame (hereinafter referred to as the probe data frame) stored in the individual data storage unit 53 by the immediately preceding probe information receiving process 100 is started. Each new probe data frame) is determined based on the value of the R flag whether or not it has real-time characteristics (step 205), and if it is real-time data, it is added to the real-time data storage unit 54 After accumulation (step 220), the real-time traffic information processing unit 56 is controlled to process all the data in the real-time data storage unit 54 to generate traffic information (step 225). If the probe data frame is not real-time data, it is additionally accumulated in the past data accumulation unit 55 (step 210), and then the statistical traffic jam information processing unit 57 is controlled to process the data in the past data accumulation unit 55. Then, traffic jam information is generated (step 215). The traffic jam information refers to information indicating how long a traffic jam exists.

  Further, the control unit 61 refers to the new probe data frame in the individual data storage unit 53 (step 230), and at least one of the R flag and the D flag is turned on for each new probe data frame. It is determined whether or not (step 235). Then, the provider identification information in the probe data frame for which the determination is affirmative is registered in the real-time data transmission unit 59 as the provider that provided the high-quality data (step 240), and the determination is negative. The provider identification information in the probe data frame is registered in the real-time data transmission unit 59 as a provider who has provided low quality data (step 245).

  At this time, the distribution traffic information distribution unit 58 passes the data generated by the real-time traffic information processing unit 56 to the real-time data transmission unit 59, and the data generated by the statistical traffic information processing unit 57 to the statistical data transmission unit 60. hand over. The real-time data transmission unit 59 and the statistical data transmission unit 60 that have received the data from the distribution traffic information distribution unit 58 receive a communication device (phone number in the case of a mobile phone) corresponding to the provider identification information registered therein. The received data is transmitted to a network address in the case of a device such as a supplier information center.

  Therefore, the provider who has transmitted the probe information determined to have high quality according to the quality index of step 235 determined in the probe information center 5 (corresponding to an example of the first quality index) The provider who can receive the traffic information and has transmitted the probe information determined to have low quality according to the quality index receives the low-quality traffic information without real-time characteristics. Note that a high / low index (corresponding to an example of a second quality index) of the quality of data to be distributed is also determined in advance by the probe information center 5.

  When the control unit 61 repeatedly executes the information providing process 200 as described above, the probe information center 5 determines whether each of the probe data frames recorded in the individual data storage unit 53 is real-time data or past data. The storage destinations are divided according to whether or not (see step 205), and the sorted data are processed as real-time traffic jam information and statistical traffic jam information, respectively (see steps 215 and 225). Whether high-quality (specifically, real-time) processing data is transmitted to each provider identification information according to the correspondence between the provider identification information and the flag in the probe data frame. Then, it is determined whether low-quality (specifically, past data that is not real time in the past) is to be transmitted (see step 235), and distribution according to the determination is performed (see steps 240 and 245).

  Also, the control unit 16 moves the probe data frame recorded in the real-time data storage unit 54 whose real-time property is lost due to the passage of time to the past data storage unit 55 as past data. Let Whether or not the real-time property is lost is determined based on a comparison between the data in the probe information section in the probe data frame and the current time.

  As described above, the probe information center 5 identifies the quality of the probe information transmitted in a state associated with the provider identification information indicating the provider of the information among the received probe information, and the identified quality is high. The processing information to be distributed to the communication device corresponding to the provider identification information is determined so that the quality of distribution increases.

  In this way, the higher the quality of the probe information transmitted to the probe information center 5 in the predetermined quality index, the better the quality of delivery of the probe information to the provider. As a result, an incentive to provide the information provider with information highly evaluated by the quality index determined by the probe information center 5 works, and as a result, the probe information center 5 can efficiently acquire necessary information. It becomes like this.

  In addition, the probe information center 5 has a large total data amount as to a quality index applied to the received probe information, with respect to all travel situation information having the same provider identification information received within the past reference time range. An indicator that the quality is higher is used.

  In this way, when a certain provider has a large number of vehicles equipped with probe devices, the probe information detected by the probe devices can be associated with the same provider identification information. In the information center 5, the amount and frequency of travel status information received from the provider is increased compared to other providers. Therefore, so-called large providers are favored.

  Further, the supplier information center 10 acquires the probe information of the mounting destination vehicles 6 and 8 detected by the plurality of probe devices 7 and 9 mounted on different vehicles, and the same probe information is obtained for each of the acquired probe information. The provider identification information is associated with each other, and the associated probe information is transmitted to the probe information center 5.

  In this way, the association of the provider identification information of the large provider having a plurality of vehicles on which the probe device is mounted with the probe information is not performed individually in the probe device, but a contractor. It is performed at the information center 10 collectively. Therefore, it is not necessary for each probe apparatus to have provider identification information.

  In the above embodiment, the vendor information center 10 corresponds to an example of a transmission device, and the probe device 2 and the vendor information center 10 correspond to an example of a communication device. Further, the control unit 61 functions as an example of the reception quality specifying unit by executing the process 100, and functions as an example of the distribution quality determining unit by executing the process 200. Moreover, each of the real-time data transmission part 59 and the statistical data transmission part 60 transmits to an example of a delivery means. The network I / F unit 12 corresponds to an example of a transmission unit, and the control unit 16 corresponds to an example of an association unit.

  Moreover, each part 11-16, 52-61 of the above-mentioned probe information center 5 and contractor information center 10 may be implement | achieved as the hardware which has the circuit for exclusive use which implement | achieves those functions, and those functions It may be realized as a computer that executes a program for realizing the above.

(Other embodiments)
As mentioned above, although embodiment of this invention was described, the scope of the present invention is not limited only to the said embodiment, The various form which can implement | achieve the function of each invention specific matter of this invention is included. It is.

  For example, in the above embodiment, high-quality distribution is transmission of real-time traffic jam information and low-quality distribution is transmission of statistical traffic jam information. However, this need not be the case. For example, high-quality distribution may be simple graphics showing real-time traffic jam information + detailed character data of real-time traffic jam information (for example, the total distance of traffic jams), and low-quality delivery may be delivery of only the simple graphics. That is, the second quality index may be anything.

  In the above embodiment, as a first quality indicator for determining the quality of probe information from a certain provider, whether or not the probe data frame from the provider has real-time characteristics, and Whether the amount of data from the provider is large is adopted. However, in addition to these, whether or not the probe data frame from the provider performs map matching (that is, whether or not the M flag is on) and whether the probe information collection frequency of the provider is high. (That is, whether or not the T flag is on) may be adopted as the first quality index.

  Further, the data items, data amount, and collection frequency of probe information required for each type of distribution service are different. Therefore, an index that increases the quality of probe data frames that can be provided to more types of distribution services may be adopted as the first quality index.

  In the above embodiment, the information distributed by the probe information center 5 is only the traffic jam information, but the probe information center 5 delivers multiple types of information (for example, traffic jam information and accident information). It may be like this. In this case, a different first quality index is set for each type of information to be distributed, each first quality index is applied to the received probe information, quality determination is performed, and the results of the quality determination are combined. It may be used to determine the quality of the distribution data.

  In the above embodiment, the processed information is distributed to the provider of the probe data frame received immediately before. However, it is not always necessary that the reception of the probe data frame from the provider and the distribution of the processed data to the provider have a one-to-one relationship. For example, when the probe information center 5 has received a probe data frame from a provider who has provided a probe data frame in the past, and has received a request for distribution of processed data from the provider, Regardless of whether or not, the processing data may be distributed.

  In this case, at the time when the probe information is provided from the provider, the probe information center 5 registers the provider identification information in the real-time data transmitter 59 and the statistical data transmitter 60, and later the provider For the first time when a distribution request is issued, the distribution of the quality corresponding to the registered content may be performed. In addition, since the probe information center 5 has correspondence information between the provider identification information and the provider's communication device, even if the provider identification information is not included in the distribution request from the provider's communication device, The probe information center 5 can specify the provider identification information corresponding to the communication device based on the correspondence information.

  In the above embodiment, the probe information center 5 changes the added value of the distribution data so that the higher the quality of the probe information, the higher the price is provided to the provider. However, with regard to distribution, in addition to this method, the higher the quality of the provided probe information, the higher the monetary consideration is paid to the provider who does not receive data distribution only by transmitting probe information. May be. For example, in response to data distribution from the probe information center 5, a data usage fee is received from the receiving side (for example, using technology such as electronic money), and the received usage fee is sent to the probe information provider, The distribution may be made according to the quality of the provided probe information.
