[0032] The following and attached Figure 1 The embodiments of the present disclosure will now be described.

[0033] The data processing device 1 of this embodiment is a smart phone held by the driver of the vehicle. Figure 1 As shown, the system includes a control unit 2 , a QR code reader 3 , a Wi-Fi communication unit 4 , a BLE communication unit 5 , a data acquisition unit 6 , a data storage unit 7 , an external communication unit 8 , and a bus 9 .

[0034] The control unit 2 is an electronic control device centered around a microcomputer comprising a CPU 11, ROM 12, and RAM 13. The various functions of the microcomputer are implemented by the CPU 11 executing a program stored on a non-migrating physical recording medium. In this example, the ROM 12 corresponds to the non-migrating physical recording medium storing the program. Furthermore, the execution of the program executes the method corresponding to the program. Alternatively, some or all of the functions performed by the CPU 11 may be implemented in hardware using one or more integrated circuits, etc. The number of microcomputers comprising the control unit 2 may be one or more.

[0035] The QR code reader 3 includes a camera (not shown) and uses the camera to capture a QR code image to read the QR code. The QR code reader 3 decodes the QR code read by the camera and outputs the decoded data as QR code data. In this embodiment, the QR code reader 3 reads a QR code attached to a battery mounted on a vehicle.

[0036] The QR code data includes one or more raw data IDs for identifying battery data related to the battery (eg, battery manufacturer and specifications), and one or more raw data values ​​indicating values ​​of the battery data corresponding to the one or more raw data IDs.

[0037] The Wi-Fi communication unit 4 performs short-range wireless communication in accordance with the Wi-Fi standard. The Wi-Fi communication unit 4 outputs received data as Wi-Fi data. In this embodiment, the Wi-Fi communication unit 4 performs data communication with a charging device that charges a battery in a vehicle.

[0038] The Wi-Fi data includes one or more raw data IDs for identifying charging device data (eg, charging power) related to the charging device, and one or more raw data values ​​indicating values ​​of the charging device data corresponding to the one or more raw data IDs.

[0039] The BLE communication unit 5 performs short-range wireless communication in accordance with Bluetooth Low Energy (BLE), an extended specification of Bluetooth. The BLE communication unit 5 outputs received data as BLE data. In this embodiment, the BLE communication unit 5 communicates data with multiple ECUs installed in the vehicle. ECU stands for Electronic Control Unit.

[0040] The BLE data includes one or more raw data IDs for identifying vehicle data related to the vehicle (eg, vehicle speed, engine speed), and one or more raw data values ​​indicating values ​​of the vehicle data corresponding to the one or more raw data IDs.

[0041] The data acquisition unit 6 is an electronic control device centered around a microcomputer comprising a CPU 21, ROM 22, and RAM 23. The various functions of the microcomputer are implemented by the CPU 21 executing a program stored on a non-migrating physical recording medium. In this example, the ROM 22 corresponds to the non-migrating physical recording medium storing the program. Furthermore, the execution of the program executes the corresponding method. Alternatively, some or all of the functions performed by the CPU 21 may be implemented in hardware using one or more integrated circuits, etc. The number of microcomputers comprising the data acquisition unit 6 may be one or more.

[0042] The data storage unit 7 is a storage device for storing various data.

[0043] The external communication unit 8 communicates data with the management center 100 via the wide area wireless communication network NW. The management center 100 acquires vehicle data related to a plurality of vehicles corresponding to the plurality of data processing devices 1 from each of the plurality of data processing devices 1 and manages the plurality of vehicles.

[0044] The bus 9 connects the control unit 2 , the QR code reader 3 , the Wi-Fi communication unit 4 , the BLE communication unit 5 , the data acquisition unit 6 , the data storage unit 7 , and the external communication unit 8 so that data can be input and output to and from each other.

[0045] Next, the procedure of the format commonality process executed by the data acquisition unit 6 will be described. The format commonality process is a process that is repeatedly executed during the operation of the data processing device 1.

[0046] If format commonization is performed, Figure 2 As shown, the CPU 21 of the data acquisition unit 6 first determines in S10 whether QR code data is output from the QR code reader 3. Here, if QR code data is not output from the QR code reader 3, the CPU 21 moves to S30.

[0047] On the other hand, when QR code data is output from the QR code reader 3 , the CPU 21 acquires the QR code data output from the QR code reader 3 in S20 , converts the QR code data into a common format described below, generates common formatted data, and then moves to S30 .

[0048] When the process proceeds to S30, the CPU 21 determines whether Wi-Fi data is output from the Wi-Fi communication unit 4. If the Wi-Fi data is not output from the Wi-Fi communication unit 4, the CPU 21 proceeds to S50.

[0049] On the other hand, when Wi-Fi data is output from the Wi-Fi communication unit 4 , the CPU 21 acquires the Wi-Fi data from the Wi-Fi communication unit 4 in S40 , converts the Wi-Fi data into the above-mentioned common format to generate common formatted data, and then moves to S50 .

[0050] When the process proceeds to S50, the CPU 21 determines whether BLE data is output from the BLE communication unit 5. If BLE data is not output from the BLE communication unit 5, the CPU 21 ends the format commonality process.

[0051] On the other hand, when BLE data is output from the BLE communication unit 5 , the CPU 21 acquires the BLE data from the BLE communication unit 5 in S60 , converts the BLE data into the above-mentioned common format to generate common formatted data, and ends the format commonization process.

[0052] like Figure 3 As shown, the common formatted data consists of a communication type field and one or more data fields.

[0053] The communication type field stores communication type information indicating the communication type. The data size of the communication type information is 8 bits. The communication type information is set to 0 or 1 depending on the communication type. When the communication type information is set to 0, the data in the data field is dynamic data. When the communication type information is set to 1, the data in the data field is static data. Dynamic data is data whose value changes within a short period of time, while static data is data whose value does not change within a short period of time. In this embodiment, Wi-Fi data and BLE data are dynamic data, and QR code data is static data.

[0054] Each data field stores a data ID and a data value. The data size of a data ID is 16 bits. The data size of a data value is variable. If the data value is a numeric value, it is represented in binary format. If the data value is a character, it is represented in UTF-8 format.

[0055] In S20 described above, CPU 21 extracts the corresponding raw data value from the QR code data for each of one or more raw data IDs contained in the acquired QR code data, thereby generating one or more data fields. CPU 21 also generates a communication type field with the communication type information set to 1. CPU 21 then concatenates the communication type field with one or more data fields to generate common formatted data.

[0056] In S40 described above, CPU 21 extracts the corresponding raw data value from the Wi-Fi data for each of one or more raw data IDs contained in the acquired Wi-Fi data, thereby generating one or more data fields. CPU 21 also generates a communication type field with the communication type information set to 0. CPU 21 then concatenates the communication type field with one or more data fields to generate common formatted data.

[0057] In S60 described above, CPU 21 extracts the corresponding raw data value from the BLE data for each of one or more raw data IDs contained in the acquired BLE data, thereby generating one or more data fields. CPU 21 also generates a communication type field with the communication type information set to 0. CPU 21 then concatenates the communication type field with one or more data fields to generate common formatted data.

[0058] Next, a description will be given of the procedure of the data extraction process executed by the control unit 2. The data extraction process is a process that is repeatedly executed during the operation of the data processing device 1.

[0059] If data extraction is performed, Figure 4 As shown, the CPU 11 of the control unit 2 first determines in S110 whether the data acquisition unit 6 has generated new common format data. Here, if the data acquisition unit 6 has not generated new common format data, the CPU 11 ends the data extraction process.

[0060] On the other hand, when the data acquisition unit 6 generates new common formatted data, the CPU 11 acquires the new common formatted data in S120 and identifies the communication type by extracting the communication type information from the acquired common formatted data.

[0061] In S130, based on the identification result in S120, the CPU 11 determines whether the data included in the acquired common formatted data is dynamic data. Specifically, if the communication type information in the common formatted data is set to 0, the CPU 11 determines that the data included in the common formatted data is dynamic data. On the other hand, if the communication type information in the common formatted data is set to 1, the CPU 11 determines that the data included in the common formatted data is static data.

[0062] Here, if the data included in the common formatted data is dynamic data, the CPU 11 in S140 sequentially extracts one data field without identification of the original data ID and original data value from the common formatted data acquired in S120 starting from the front end of the common formatted data.

[0063] In S150 , the CPU 11 identifies the original data ID of the data field extracted in S140 .

[0064] In S160 , the CPU 11 identifies the original data value of the data field extracted in S140 .

[0065] In S170, the CPU 11 updates the original data value identified in S160. Specifically, Figure 5 As shown, the CPU 11 establishes a correspondence between the raw data ID identified in S150 and the raw data value identified in S160, and stores them in the RAM 13. Furthermore, if the raw data ID identified in S150 is not stored in the RAM 13, the CPU 11 stores the raw data ID identified in S150 and the raw data value identified in S160 in the RAM 13. On the other hand, if the raw data ID identified in S150 is already stored in the RAM 13, the CPU 11 overwrites the raw data value identified in S160 in the storage area storing the raw data value corresponding to the raw data ID identified in S150.

[0066] like Figure 4 As shown, in S180, the CPU 11 determines whether there is a next data field after the data field extracted in S140. Here, if there is a next data field after the data field extracted in S140, the CPU 11 moves to S140. On the other hand, if there is no next data field after the data field extracted in S140, the CPU 11 ends the data extraction process.

[0067] Furthermore, in S130 , when the data included in the common format data is not dynamic data, the CPU 11 extracts one data field in S190 in the same manner as in S140 .

[0068] In S200 , the CPU 11 recognizes the original data ID of the data field extracted in S190 , similarly to S150 .

[0069] In S210 , the CPU 11 recognizes the original data value of the data field extracted in S190 in the same manner as in S160 .

[0070] In S220 , the CPU 11 updates the raw data value recognized in S210 in the same manner as in S170 .

[0071] At S230, the CPU 11 determines whether there is a next data field following the data field extracted at S190. If there is a next data field following the data field extracted at S190, the CPU 11 proceeds to S190. On the other hand, if there is no next data field following the data field extracted at S190, the CPU 11 executes a data normalization instruction at S240 and terminates the data extraction process.

[0072] Next, a description will be given of the procedure of the data normalization process executed by the control unit 2. The data normalization process is a process that is repeatedly executed during the operation of the data processing device 1.

[0073] If data normalization is performed, Figure 6 As shown, the CPU 11 of the control unit 2 first determines whether the preset data normalization conditions are met in S310. In this embodiment, the data normalization conditions include a first periodic normalization condition, a second periodic normalization condition, a third periodic normalization condition, a first event normalization condition, and a second event normalization condition.

[0074] The first periodic normalization condition is a first period (e.g., one second) that has passed since the first periodic normalization condition was last met. The second periodic normalization condition is a second period (e.g., one minute) that has passed since the second periodic normalization condition was last met. The third periodic normalization condition is a third period (e.g., one hour) that has passed since the third periodic normalization condition was last met.

[0075] The first event normalization condition is that the control unit 2 executes a data normalization instruction. The second event normalization condition is that the raw data value corresponding to the raw data ID that matches the preset second event target data ID changes.

[0076] Here, if the data normalization condition is not satisfied, the CPU 11 terminates the data normalization process. On the other hand, if the data normalization condition is satisfied, the CPU 11 obtains one or more raw data IDs that are pre-set for the satisfied data normalization condition and one or more raw data values ​​corresponding to the one or more raw data IDs in S320.

[0077] At S330, the CPU 11 performs data normalization using the one or more raw data IDs and one or more raw data values ​​acquired at S320 to generate standardized data. Standardized data consists of a standard ID and a standard data value. Specifically, the CPU 11 refers to a normalization table stored in the ROM 12 and converts the one or more raw data IDs and one or more raw data values ​​into one or more standard IDs and one or more standard data values.

[0078] The standardized table has multiple normalized information and multiple semantic information.

[0079] Normalization information is information for normalizing raw data values ​​so that the same physical quantity becomes the same value regardless of the type of vehicle or vehicle manufacturer.

[0080] The normalization information includes ID conversion information for converting an original data ID into a standard ID, and data value conversion information for converting an original data value into a standard data value.

[0081] ID conversion information is used to convert data IDs so that data of the same type retains the same value regardless of vehicle type or manufacturer. For example, the original data ID for "vehicle speed" varies depending on the vehicle type and manufacturer. In contrast, the original data ID for "vehicle speed" is converted to a single standard ID based on the ID conversion information, regardless of vehicle type or manufacturer.

[0082] Data value conversion information includes, for example, "Significant digits," "Resolution," "Offset," and "Unit." "Significant digits" indicates the number of significant digits in the standard data value. "Resolution" indicates the numerical value per bit. "Offset" indicates the amount of offset in the data value. "Unit" indicates the unit of the data.

[0083] In addition, the data value conversion information includes, for example, a table of correspondences between original data values ​​and standard data values. For example, the table establishes correspondences between the original data values ​​"0", "1", "2", and "3" and the gear positions "P", "R", "N", and "D", respectively.

[0084] Semantic information is information (such as a calculation expression or a conversion table) used to convert normalized raw data values ​​into meaningful vehicle data. Semantic information may also use raw data values ​​before normalization.

[0085] The semantic information includes a "standard ID" corresponding to the standard data value calculated through conversion, and a conversion formula or table for converting the raw data value into the standard data value. For example, the conversion formula converts the raw data value representing the "steering zero point" to the standard data value representing the "steering angle" by subtracting the raw data value representing the "steering movement angle."

[0086] In S340, the CPU 11 updates the standardized data generated in S330. Specifically, Figure 7As shown, the CPU 11 establishes a correspondence between the standard ID and the standard data value for the standardized data generated in S330 and stores the correspondence in the data storage unit 7. Furthermore, if the standard ID of the standardized data generated in S330 is not stored in the data storage unit 7, the CPU 11 stores the standard ID and the standard data value of the standardized data generated in S330 in the data storage unit 7. On the other hand, if the standard ID of the standardized data generated in S330 is stored in the data storage unit 7, the CPU 11 overwrites the standard data value of the standardized data generated in S330 in the storage area where the standard data value corresponding to the standard ID of the standardized data generated in S330 is stored.

[0087] like Figure 6 As shown, in S350, CPU 11 determines whether the first event normalization condition or the second event normalization condition is satisfied. If neither the first event normalization condition nor the second event normalization condition is satisfied, CPU 11 terminates the data normalization process. On the other hand, if either the first event normalization condition or the second event normalization condition is satisfied, CPU 11 executes a data transmission instruction in S360, terminating the data normalization process.

[0088] Next, a description will be given of the procedure of the data transmission process executed by the control unit 2. The data transmission process is a process that is repeatedly executed during the operation of the data processing device 1.

[0089] If data transmission is executed, Figure 8 As shown, the CPU 11 of the control unit 2 first determines whether a preset data transmission condition is satisfied in S410. In this embodiment, the data transmission condition includes a first periodic transmission condition, a second periodic transmission condition, a third periodic transmission condition, and an event transmission condition.

[0090] The first periodic transmission condition is when a first period (e.g., one second) has passed since the first periodic transmission condition was last met. The second periodic transmission condition is when a second period (e.g., one minute) has passed since the second periodic transmission condition was last met. The third periodic transmission condition is when a third period (e.g., one hour) has passed since the third periodic transmission condition was last met. The event transmission condition is when the control unit 2 executes a data transmission instruction.

[0091] Here, if the data transmission condition is not satisfied, the CPU 11 ends the data transmission process. On the other hand, if the data transmission condition is satisfied, the CPU 11 acquires one or more normalized data preset for the satisfied data normalization condition from the data storage unit 7 in S420.

[0092] In S430 , the CPU 11 causes the external communication unit 8 to execute a process of transmitting the one or more standardized data acquired in S420 to the management center 100 , and ends the data transmission process.

[0093] The data processing device 1 configured in this manner includes a BLE communication unit 5 , a Wi-Fi communication unit 4 , a QR code reader 3 , a data acquisition unit 6 , a control unit 2 , a data storage unit 7 , and an external communication unit 8 .

[0094] The BLE communication unit 5 acquires vehicle data related to the vehicle from the vehicle by performing short-range wireless communication in accordance with BLE.

[0095] The Wi-Fi communication unit 4 acquires charging device data related to the charging device from the charging device by performing short-range wireless communication in accordance with the Wi-Fi standard.

[0096] The QR code reader 3 reads a QR code attached to a battery mounted on a vehicle, thereby acquiring battery data related to the battery from the battery.

[0097] The data acquisition unit 6 and the control unit 2 generate normalized data including a standard ID for identifying the vehicle data and a standard data value for normalizing the vehicle data value, for the vehicle data acquired by the BLE communication unit 5 .

[0098] The data acquisition unit 6 and the control unit 2 generate normalized data including a standard ID for identifying the charging device data and a standard data value for normalizing the charging device data value, based on the charging device data acquired by the Wi-Fi communication unit 4 .

[0099] The data acquisition unit 6 and the control unit 2 generate normalized data including a standard ID for identifying the battery data and a standard data value for normalizing the battery data value, based on the battery data acquired by the QR code reader 3 .

[0100] The data accumulation unit 7 stores normalized data and normalized data.

[0101] When a preset data transmission condition is satisfied, the control unit 2 and the external communication unit 8 transmit the standardized data stored in the data storage unit 7 to the management center 100 .

[0102] Such a data processing device 1 converts a piece of data into a format consisting of a data ID and a data value, and normalizes multiple data obtained through different acquisition methods to generate multiple standardized data, so that data can be provided in a common data format that does not depend on the acquisition method, making it easy to use the data.

[0103] Furthermore, in data processing device 1, data acquisition unit 6, which generates common formatted data, is separate from the other components of data processing device 1 (i.e., control unit 2, QR code reader 3, Wi-Fi communication unit 4, BLE communication unit 5, data storage unit 7, and external communication unit 8). Therefore, when adding a new acquisition method to data processing device 1, all that is required is to add a new data communication unit (e.g., QR code reader 3, Wi-Fi communication unit 4, BLE communication unit 5) and modify the configuration of data acquisition unit 6, making it easier to expand data processing device 1.

[0104] Furthermore, the data acquisition unit 6 determines whether the vehicle data acquired by the BLE communication unit 5, the charging device data acquired by the Wi-Fi communication unit 4, and the battery data acquired by the QR code reader 3 are dynamic or static data, and sets communication type information indicating whether the data is dynamic or static in the standardized data. Specifically, the data acquisition unit 6 sets the communication type information in the standardized data by appending the communication type information to the common formatted data.

[0105] The control unit 2 and the external communication unit 8 transmit standardized data when the data transmission conditions set according to the communication type information are met. In this embodiment, for dynamic data, one of the first periodic transmission condition, the second periodic transmission condition, and the third periodic transmission condition is set as the data transmission condition, and for static data, an event transmission condition is set.

[0106] Such a data processing device 1 can transmit dynamic data, whose data values ​​change within a short period of time, to the management center 100 at an appropriate timing corresponding to the frequency of the data value changes. This allows the management center 100 to manage changes in dynamic data. Furthermore, the data processing device 1 can also transmit static data, whose data values ​​do not change within a short period of time, to the management center 100 at an appropriate timing corresponding to the frequency of the data value changes. This allows the data processing device 1 to prevent wasteful transmission of static data to the management center 100, even though the static data's value has not changed.

[0107] Furthermore, when the communication type information indicates static data, the data transmission condition (i.e., event transmission condition) is set to transmit the standardized data corresponding to the static data immediately after it is generated. This allows the data processing device 1 to provide the standardized data corresponding to the static data to the management center 100 at the earliest possible timing.

[0108] Furthermore, when the communication type information indicates dynamic data, the data transmission conditions (i.e., the first periodic transmission condition, the second periodic transmission condition, and the third periodic transmission condition) are set so that standardized data corresponding to the dynamic data is transmitted every time a predetermined transmission period (i.e., the first period, the second period, and the third period) passes. This allows the data processing device 1 to provide standardized data to the management center 100 at any timing, regardless of the data acquisition frequency of each data acquisition method used by the QR code reader 3, the Wi-Fi communication unit 4, and the BLE communication unit 5.

[0109] The vehicle data acquired by the BLE communication unit 5 is appended with a raw data ID for identifying the vehicle data. The charging device data acquired by the Wi-Fi communication unit 4 is appended with a raw data ID for identifying the charging device data. The battery data acquired by the QR code reader 3 is appended with a raw data ID for identifying the battery data.

[0110] The data acquisition unit 6 then converts the vehicle data acquired by the BLE communication unit 5 into shared formatted data containing a raw data ID and raw data values ​​representing the vehicle data. The data acquisition unit 6 also converts the charging device data acquired by the Wi-Fi communication unit 4 into shared formatted data containing a raw data ID and raw data values ​​representing the charging device data. The data acquisition unit 6 also converts the battery data acquired by the QR code reader 3 into shared formatted data containing a raw data ID and raw data values ​​representing the battery data.

[0111] The control unit 2 generates normalized data by normalizing the raw data values ​​included in the common formatted data.

[0112] Such a data processing device 1 can generate standardized data at an arbitrary timing that is not dependent on the data acquisition frequency of each data acquisition method of the QR code reader 3 , the Wi-Fi communication unit 4 , and the BLE communication unit 5 .

[0113] Furthermore, the data acquisition unit 6 determines whether the vehicle data acquired by the BLE communication unit 5 is dynamic data or static data, and adds communication type information indicating whether the data is dynamic data or static data to the common formatted data.

[0120] Furthermore, the standard data ID included in the normalized data of the charging device data and the battery data corresponds to the second data ID, and the standard data value included in the normalized data of the charging device data and the battery data corresponds to the second normalized data.
