[0001] The present invention relates to the technical field of vehicle data management, and in particular to a vehicle data collection and sorting system for vehicle data analysis. Background Art

[0002] At present, with the improvement of vehicle intelligence and information level, the amount of data generated by vehicles is constantly increasing, including but not limited to sensor data collected by several types of sensors arranged on the vehicle and network communication data recorded by the vehicle central control. These data are of great significance to vehicle manufacturers, maintenance service providers and car owners.

[0003] However, how to efficiently collect, organize and quickly analyze this data, and then quickly locate abnormal vehicles to ultimately clearly define vehicles in normal and abnormal states, is still a considerable challenge in the current field of vehicle data analysis. Summary of the invention

[0004] In order to solve the above problems, an object of the present invention is to provide a vehicle data collection and organization system for vehicle data analysis.

[0005] The object of the present invention can be achieved by the following technical solutions: A vehicle data collection and collation system for vehicle data analysis, comprising a dispatch center, wherein the dispatch center is communicatively connected with a data collection module, a transmission control module, a data analysis module and a visualization collation module;

[0006] The data collection module is used to collect the location information, sensor data and network communication data corresponding to a number of vehicles, and use them as the data to be analyzed for each vehicle, and send all the data to be analyzed for the vehicles to the dispatch center;

[0007] The dispatch center analyzes the occupancy status of a plurality of data analysis devices, and associates corresponding transmission authorization codes and control protocols for vehicle data to be analyzed of different vehicles;

[0008] The transmission control module is used to transmit the vehicle data to be analyzed corresponding to different transmission authorization codes and control protocols to the data analysis device where the occupancy state is available, and establish a time-series feature control chain for the transmission process, and locate the abnormal transmission node by the time-series feature control chain;

[0009] The data analysis module is used to synchronously perform data analysis on vehicle data to be analyzed in a plurality of data analysis devices;

[0010] The visualization module is used to organize the analysis results after data analysis and to visualize the analysis results.

[0011] Furthermore, the data collection module collects the location information, sensor data and network communication data corresponding to the plurality of vehicles and uses the data to be analyzed as the data of the respective vehicles, including:

[0012] Several vehicles are numbered and recorded as i, i = 1, 2, 3, ..., n, n is a natural number greater than 0, each vehicle sends an information building request to the data collection module, and the information building request corresponding to the vehicle numbered i is recorded as Request[i];

[0013] When the data collection module obtains an information building application Request[i] sent by a vehicle, several collection terminals set by the data collection module obtain the location information, sensor data and network communication data of the vehicle corresponding to Request[i], and record the location information, sensor data and network communication data corresponding to the vehicle numbered i as Location-Info[i], Sensor-data[i] and Network-data[i] respectively. The location information, sensor data and network communication data corresponding to each vehicle are used as the corresponding vehicle data to be analyzed, and the vehicle data to be analyzed corresponding to the vehicle numbered i is recorded as τ[i], and τ[i] = {Location-Info[i], Sensor-data[i], Network-data[i]};

[0014] Among them, the sensor data includes vehicle speed sensor data, steering sensor data, tire pressure sensor data, body stability sensor data and engine speed sensor data, and the network communication data includes vehicle navigation data and driving behavior data.

[0015] Furthermore, the process of sending all the vehicle data to be analyzed to the dispatch center includes:

[0016] Construct a wireless transmission link between each collection terminal and the dispatch center. The wireless transmission link is preset with corresponding link standard parameters. The link standard parameters include standard transmission bandwidth, standard transmission packet loss rate and standard transmission delay rate, which are denoted as DK 标准 , DB 标准 and YC 标准 ;

[0017] The vehicle data to be analyzed corresponding to all vehicles are sent to the dispatch center through several wireless transmission links, and the actual transmission bandwidth, actual transmission packet loss rate and actual transmission delay rate corresponding to each wireless transmission link when transmitting the vehicle data to be analyzed are obtained, which are recorded as DK respectively. 实际 , DB 实际 and YC 实际, set the fluctuation allowable values ​​corresponding to the standard transmission bandwidth, standard transmission packet loss rate and standard transmission delay rate, which are denoted as ZY1, ZY2 and ZY3 respectively;

[0018] When | DK 标准 -DK 实际 When |≤ZY1, it means that the actual transmission bandwidth of the wireless transmission link is qualified, otherwise, the actual transmission bandwidth of the wireless transmission link is abnormal;

[0019] When | DB 标准 -DB 实际 |≤ZY2, it means that the actual transmission packet loss rate of the wireless transmission link is qualified, otherwise, the actual transmission packet loss rate of the wireless transmission link is abnormal;

[0020] When | YC 标准 -YC 实际 |≤ZY3, it means that the actual transmission delay rate of the wireless transmission link is qualified, otherwise, the actual transmission delay rate of the wireless transmission link is abnormal;

[0021] A wireless transmission link whose actual transmission bandwidth, actual transmission packet loss rate and actual transmission delay rate are all qualified is marked as a normal link, and a wireless transmission link whose actual transmission bandwidth, actual transmission packet loss rate and actual transmission delay rate are abnormal is marked as an abnormal link, and the wireless transmission link is reconstructed for the collection end corresponding to the abnormal link until the reconstructed wireless transmission link is a normal link.

[0022] Furthermore, the process of the dispatch center analyzing the occupancy status of a plurality of data analysis devices and associating corresponding transmission authorization codes and control protocols for vehicle data to be analyzed of different vehicles includes:

[0023] Several data analysis devices are set up, and the dispatch center obtains the device occupancy rate corresponding to each data analysis device. The device occupancy rate indicates the proportion of the data volume currently being processed by the data analysis device to the total data volume that the data analysis device can process;

[0024] The device occupancy rate is denoted as η, and the value range of η is [0, 1]. When the value of η is [0, 0.6], the occupancy state of the data analysis device is set to the available state. When the value of η is (0.6, 1], the occupancy state of the data analysis device is set to the disabled state.

[0025] Corresponding transmission authorization codes and control protocols are associated with the vehicle data to be analyzed of different vehicles, wherein the transmission authorization code corresponding to the vehicle numbered i is recorded as Sign[i], and the types of control protocols include transport layer protocol, network layer protocol, application layer protocol, session layer protocol and data link layer protocol. When the transport layer protocol, network layer protocol, application layer protocol, session layer protocol and data link layer protocol of each vehicle corresponding to the vehicle data to be analyzed are in their respective correct protocol formats and protocol contents, the respective control protocol configurations are completed; otherwise, continue to configure the protocol parts that do not conform to the correct protocol format and protocol content until the control protocol configuration is completed.

[0026] Furthermore, the transmission control module transmits the vehicle data to be analyzed corresponding to different transmission authorization codes and control protocols to the data analysis device whose occupancy state is available, and establishes a time-series feature control chain for the transmission process, including:

[0027] Set the data transmission period of the transmission control module, denoted as T 传输 , T 传输 =[t 始 , t 终 ], where t 始 is the starting time of the data transmission period, t 终 is the end time of the data transmission period, at t 始 At the corresponding start time point, the transmission control module transmits the vehicle data to be analyzed after each association has completed the respective transmission authorization code to the data analysis device whose occupancy state is in the available state according to the respective corresponding control protocols;

[0028] Get the transmission duration corresponding to the data transmission period and record it as T`, then T`=|t 终 -t 始 |, set the unit duration used to analyze all timing characteristics during the transmission process, and record it as t 单位 , according to T` and t 单位 Divide into X monitoring time points, X = T` / t 单位 , when X is a decimal, round X upwards;

[0029] The timing features corresponding to the vehicle data transmission process to be analyzed at each monitoring time point are obtained, and the initial model chain is constructed through deep learning. The model chain consists of several chain nodes, each of which is initially an empty node. A chain node is assigned to the timing features corresponding to each monitoring time point, and the chain node imports the corresponding timing features. All chain nodes with imported timing features are connected in order from front to back on the model chain according to the chronological order of the monitoring time points, and then the initial model chain is converted into the final time-timing feature control chain.

[0030] Furthermore, the process of locating abnormal transmission nodes by the time-series feature control chain includes:

[0031] The time series feature corresponding to each monitoring time point is the transmission feature information of the vehicle data to be analyzed at different time points during the entire transmission process. The transmission feature information includes data noise, data flow change trend and data jitter frequency. The normal value range corresponding to the data noise and the frequency threshold corresponding to the data jitter frequency are set. The data flow change trend includes abnormal increase in flow trend, normal maintenance of flow trend and abnormal decrease in flow trend.

[0032] Judge each chain node included in the time-series feature control chain in turn, and locate the chain node where any of the conditions that the data noise is not within the normal value range, the data flow change trend is not within the normal flow trend, or the data jitter frequency is greater than the frequency threshold is met as an abnormal transmission node, and locate all chain nodes where the data noise is within the normal value range, the data flow change trend is within the normal flow trend, and the data jitter frequency is less than or equal to the frequency threshold as normal transmission nodes;

[0033] A number threshold corresponding to the number of abnormal transmission nodes is set. When the number of abnormal transmission nodes is greater than or equal to the number threshold, the corresponding vehicle data to be analyzed is retransmitted. When the number of abnormal transmission nodes is less than the number threshold, no operation is performed.

[0034] Furthermore, the process of the data analysis module synchronously performing data analysis on the vehicle data to be analyzed in a plurality of data analysis devices includes:

[0035] A position range set corresponding to the position information in the vehicle data to be analyzed, a sensor standard set corresponding to the sensor data, and a communication standard set corresponding to the network communication data are set, wherein the position range set includes position information under several standard position ranges, the sensor standard set records the normal value ranges corresponding to the vehicle speed sensor data, steering sensor data, tire pressure sensor data, vehicle body stability sensor data, and engine speed sensor data under the normal state of the vehicle, and the communication standard set records the normal value ranges corresponding to the vehicle navigation data and driving behavior data under the normal state of the vehicle;

[0036] When any of the following conditions holds true: the location information in the vehicle data to be analyzed does not conform to the location range set, the sensor data does not conform to the sensing standard set, and the network communication data does not conform to the communication standard set, the analysis result of the data analysis on the vehicle data to be analyzed is: "The vehicle corresponding to the current vehicle data to be analyzed is abnormal". Otherwise, the analysis result of the data analysis on the vehicle data to be analyzed is: "The vehicle corresponding to the current vehicle data to be analyzed is normal".

[0037] Furthermore, the visualization collating module collates the analysis results of the data to be analyzed for a number of vehicles, and the process of visually displaying the analysis results includes:

[0038] The visualization sorting module is provided with a safe vehicle visualization display partition and an abnormal vehicle visualization display partition. The vehicle information of all vehicles whose analysis results are "the vehicle corresponding to the current vehicle data to be analyzed is normal" is sorted and visualized in the safe vehicle visualization display partition, and the vehicle information of all vehicles whose analysis results are "the vehicle corresponding to the current vehicle data to be analyzed is abnormal" is sorted and visualized in the abnormal vehicle visualization display partition.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] The data collection module collects the location information, sensor data and network communication data corresponding to several vehicles as their respective vehicle data to be analyzed and sends them to the dispatch center. The dispatch center analyzes the occupancy status of several data analysis devices, and associates corresponding transmission authorization codes and control protocols for different vehicle data to be analyzed. The transmission control module transmits the vehicle data to be analyzed corresponding to different transmission authorization codes and control protocols to the data analysis device with an occupancy status of available for data analysis. After the data analysis is completed, the normal and abnormal vehicle data to be analyzed are located, and then the corresponding normal vehicles and abnormal vehicles are distinguished, and the vehicle information corresponding to the normal vehicles and the abnormal vehicles are displayed separately in the visualization sorting module. On the one hand, several data analysis devices in an available state perform data analysis synchronously, which improves the efficiency of data analysis and achieves rapid positioning of abnormal vehicles; on the other hand, it realizes rapid sorting and clear display of the vehicle information of abnormal vehicles and normal vehicles. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Figure 1 It is a schematic diagram of the present invention. DETAILED DESCRIPTION

[0043] The data collection module is used to collect the location information, sensor data and network communication data corresponding to a number of vehicles, and use them as the data to be analyzed for each vehicle, and send all the data to be analyzed for the vehicles to the dispatch center;

[0044] The dispatch center analyzes the occupancy status of a plurality of data analysis devices, and associates corresponding transmission authorization codes and control protocols for vehicle data to be analyzed of different vehicles;

[0045] The transmission control module is used to transmit the vehicle data to be analyzed corresponding to different transmission authorization codes and control protocols to the data analysis device where the occupancy state is available, and establish a time-series feature control chain for the transmission process, and locate the abnormal transmission node by the time-series feature control chain;

[0046] The data analysis module is used to synchronously perform data analysis on vehicle data to be analyzed in a plurality of data analysis devices;

[0047] The visualization module is used to organize the analysis results after data analysis and to visualize the analysis results.

[0048] It should be further explained that, in the specific implementation process, the data collection module collects the location information, sensor data and network communication data corresponding to a number of vehicles and uses them as the data to be analyzed for each vehicle, including:

[0049] Number several vehicles and record the number as i, then i = 1, 2, 3, ..., n, where n is a natural number greater than 0. Each vehicle sends an information building request to the data collection module, and the information building request corresponding to the vehicle numbered i is recorded as Request[i];

[0050] The data collection module is provided with several collection terminals, and the operation states corresponding to each collection terminal include state A, state B and state C, wherein state A indicates that the collection terminal is in normal operation, state B indicates that the collection terminal is in abnormal operation, and state C indicates that the collection terminal is idle;

[0051] The initial operating state of all collection terminals is C state. When the data collection module obtains an information building application Request[i] sent by a vehicle, a collection terminal in C state is converted to A state. After receiving the information building application Request[i], the collection terminal in A state further obtains the location information, sensor data and network communication data of the vehicle corresponding to Request[i].

[0052] The location information, sensor data, and network communication data corresponding to the vehicle numbered i are respectively recorded as Location-Info[i], Sensor-data[i], and Network-data[i], where the location information is obtained by a GPS device arranged on the vehicle, several types of sensors are arranged on the vehicle to obtain the sensor data of the vehicle, and the corresponding central control device on the vehicle obtains the network communication data corresponding to the vehicle itself;

[0053] The location information, sensor data, and network communication data corresponding to each vehicle are used as the corresponding vehicle data to be analyzed, and the vehicle data to be analyzed is stored at the receiving collection end, wherein the vehicle data to be analyzed corresponding to the vehicle numbered i is recorded as τ[i], then τ[i] = {Location-Info[i], Sensor-data[i], Network-data[i]};

[0054] More specifically, the sensor data includes vehicle speed sensor data, steering sensor data, tire pressure sensor data, vehicle stability sensor data, and engine speed sensor data, and the network communication data includes vehicle navigation data and driving behavior data;

[0055] When the collecting end is in the B state, any other collecting end in the C state will be converted to the A state, and the collecting end converted to the A state will receive all the vehicle data to be analyzed corresponding to the collecting end in the B state; that is, the collecting end in the B state will send all the vehicle data to be analyzed collected by itself to the new collecting end converted to the A state for storage.

[0056] It should be further explained that, in the specific implementation process, the process of sending all the vehicle data to be analyzed to the dispatch center includes:

[0057] When the vehicle data to be analyzed of all vehicles are stored by the corresponding collecting terminals, a wireless transmission link is constructed between each collecting terminal and the dispatching center, wherein the wireless transmission link is preset with corresponding link standard parameters, and the link standard parameters include standard transmission bandwidth, standard transmission packet loss rate and standard transmission delay rate;

[0058] The vehicle data to be analyzed corresponding to all vehicles are sent to the dispatch center through several wireless transmission links, and the actual transmission bandwidth, actual transmission packet loss rate and actual transmission delay rate corresponding to each wireless transmission link when transmitting the vehicle data to be analyzed are obtained;

[0059] The standard transmission bandwidth, standard transmission packet loss rate and standard transmission delay rate are respectively denoted as DK 标准 , DB 标准 and YC 标准 , the actual transmission bandwidth, actual transmission packet loss rate and actual transmission delay rate are respectively denoted as DK 实际 , DB 实际 and YC 实际 ;

[0060] Set the fluctuation tolerance values ​​corresponding to the standard transmission bandwidth, the standard transmission packet loss rate and the standard transmission delay rate respectively. The fluctuation tolerance value indicates the numerical tolerance value between the actual transmission bandwidth, the actual transmission packet loss rate and the actual transmission delay rate and the corresponding standard transmission bandwidth, the standard transmission packet loss rate and the standard transmission delay rate when the wireless transmission link is transmitting the data to be analyzed by the vehicle;

[0061] The fluctuation allowable values ​​corresponding to the standard transmission bandwidth, the standard transmission packet loss rate and the standard transmission delay rate are respectively denoted as ZY1, ZY2 and ZY3;

[0062] When | DK 标准 -DK 实际 When |≤ZY1, it means that the actual transmission bandwidth of the wireless transmission link is qualified, otherwise, the actual transmission bandwidth of the wireless transmission link is abnormal;

[0063] When | DB 标准 -DB 实际 |≤ZY2, it means that the actual transmission packet loss rate of the wireless transmission link is qualified, otherwise, the actual transmission packet loss rate of the wireless transmission link is abnormal;

[0064] When | YC 标准 -YC 实际 |≤ZY3, it means that the actual transmission delay rate of the wireless transmission link is qualified, otherwise, the actual transmission delay rate of the wireless transmission link is abnormal;

[0065] The wireless transmission links whose actual transmission bandwidth, actual transmission packet loss rate and actual transmission delay rate are all qualified are marked as normal links;

[0066] Any wireless transmission link that is abnormal in actual transmission bandwidth, actual transmission packet loss rate, and actual transmission delay rate is marked as an abnormal link, and the wireless transmission link is reconstructed for the collection end corresponding to the abnormal link until the reconstructed wireless transmission link is a normal link.

[0067] It should be further explained that, in the specific implementation process, the dispatch center analyzes the occupancy status of several data analysis devices, and associates the corresponding transmission authorization code and control protocol for the vehicle data to be analyzed of different vehicles, including:

[0068] Set up a number of data analysis devices, each of which has a unique device number. The device number serves as the identity certificate of each data analysis device. The device number is recorded in the form of No-Number, where Number is an eight-digit number consisting of 0-9, and Number cannot use 0 as the highest digit;

[0069] The dispatch center obtains the device occupancy rate corresponding to each data analysis device, where the device occupancy rate indicates the proportion of the data volume currently being processed by the data analysis device to the total data volume that the data analysis device can process;

[0070] The equipment occupancy rate is recorded as η, and the value range of η is [0, 1];

[0071] When the device occupancy rate η of the data analysis device takes a value of [0, 0.6], the occupancy state of the corresponding data analysis device is set to an available state, where the available state indicates that the current data analysis device can still perform subsequent processing of the vehicle data to be analyzed;

[0072] When the device occupancy rate η of the data analysis device is (0.6, 1], the occupancy state of the corresponding data analysis device is set to a disabled state, and the disabled state indicates that the current data analysis device cannot perform subsequent processing of the vehicle data to be analyzed;

[0073] Associating the vehicle data to be analyzed corresponding to each vehicle with different numbers with their respective transmission authorization codes and control protocols, wherein the transmission authorization code corresponding to the vehicle with number i is recorded as Sign[i], and the transmission authorization code Sign[i] is a subsequent verification credential after the vehicle data to be analyzed corresponding to the vehicle with number i is transmitted to the data analysis device, and judging whether the transmission authorization code is changed to determine whether the corresponding vehicle data to be analyzed is tampered with;

[0074] The types of control protocols include transport layer protocols, network layer protocols, application layer protocols, session layer protocols and data link layer protocols. When the transport layer protocols, network layer protocols, application layer protocols, session layer protocols and data link layer protocols corresponding to the vehicle data to be analyzed are in their respective correct protocol formats and protocol contents, the respective control protocol configurations are completed; otherwise, continue to configure the protocol parts that do not conform to the correct protocol formats and protocol contents until the control protocol configuration is completed.

[0075] It should be noted that the transport layer protocol is used for end-to-end data transmission to ensure data reliability and integrity. It generally includes TCP, UDP and SCTP. The characteristics of TCP are to ensure that data arrives in order, detect and correct errors in transmission, and UDP is simple, low-latency and suitable for real-time applications, but does not guarantee the integrity and order of data transmission. The characteristics of SCTP are to support multiple data streams and data packet reordering. The corresponding transport layer protocol should be selected according to the specific situation. The network layer protocol is used for data forwarding and routing between different networks, generally including IP and ICMP. IP includes IPv4 and IPv6, providing logical address and data packet forwarding functions. ICMP is used for network fault detection and reporting. The corresponding network layer protocol should be selected according to the specific situation. The application layer protocol provides data exchange services for applications. The session layer protocol is used for session establishment, maintenance and termination. The data link layer protocol is used for data link layer transmission and error detection.

[0076] It should be further explained that, in the specific implementation process, the transmission control module transmits the vehicle data to be analyzed corresponding to different transmission authorization codes and control protocols to the data analysis device whose occupancy state is available, and establishes a time-series feature control chain for the transmission process, including:

[0077] Set the data transmission period of the transmission control module, and record the data transmission period as T 传输 , then T 传输 =[t 始 , t 终 ], where t 始 is the starting time of the data transmission period, t 终 The end time point of the data transmission period;

[0078] In t 始 At the corresponding start time point, the transmission control module transmits the vehicle data to be analyzed after each association has completed the respective transmission authorization code to the data analysis device whose occupancy state is in the available state according to the respective corresponding control protocols;

[0079] Get the transmission duration corresponding to the data transmission period and record it as T`, then T`=|t 终 -t 始 |, set the unit duration used to analyze all timing characteristics during the transmission process, and record the unit duration as t 单位 , according to T` and t 单位 Divide into X monitoring time points, where X = T` / t 单位 ;

[0080] When X is a decimal, round X upwards;

[0081] Obtain the time series characteristics corresponding to the data transmission process of the vehicle to be analyzed at each monitoring time point, number several monitoring time points, and record the number as j, then j = 1, 2, 3, ..., X, X is an integer greater than 0;

[0082] An initial model chain is constructed through deep learning. The model chain consists of several chain nodes. Each chain node is initially an empty node, which means that no data is stored. A chain node is assigned to the timing feature corresponding to each monitoring time point, and the chain node imports the corresponding timing feature. All chain nodes with imported timing features are connected in order from front to back on the model chain according to the chronological order of the monitoring time points, thereby converting the initial model chain into the final time-timing feature control chain.

[0083] It should be further explained that, in the specific implementation process, the process of locating abnormal transmission nodes by the time-series feature control chain includes:

[0084] The time series characteristics corresponding to each monitoring time point are the transmission characteristic information of the vehicle data to be analyzed at different time points during the entire transmission process, and the transmission characteristic information includes data noise, data flow change trend and data jitter frequency;

[0085] Setting a normal value range corresponding to data noise and a frequency threshold corresponding to data jitter frequency, wherein the data flow change trend includes abnormal increase in flow trend, normal maintenance of flow trend and abnormal decrease in flow trend;

[0086] It should be noted that the abnormal increase in traffic trend and the abnormal decrease in traffic trend indicate that the traffic required to maintain the transmission of the vehicle data to be analyzed at the corresponding time point exceeds the preset traffic threshold. Both are situations where the data traffic change trend is abnormal.

[0087] The data noise, data flow change trend and data jitter frequency corresponding to each chain node included in the time-series feature control chain are judged in turn, and the chain node whose data noise is not within the normal value range, or the data flow change trend is not within the normal flow trend, or the data jitter frequency is greater than the frequency threshold, is located as an abnormal transmission node;

[0088] All the chain nodes whose data noise is within the normal value range, whose data flow change trend is within the normal flow trend and whose data jitter frequency is less than or equal to the frequency threshold are positioned as normal transmission nodes;

[0089] A number threshold corresponding to the number of abnormal transmission nodes is set. When the number of abnormal transmission nodes is greater than or equal to the number threshold, the corresponding vehicle data to be analyzed is retransmitted. When the number of abnormal transmission nodes is less than the number threshold, no operation is performed.

[0090] It should be noted that data noise refers to random or irregular fluctuations or interferences in the data. These fluctuations do not represent real changes or trends in the data, but are caused by various random factors, such as sensor measurement errors, interference in communication channels, and changes in environmental conditions. The data flow change trend is used to reflect the flow changes of the data to be analyzed by the vehicle transmitted at each monitoring time point. Data jitter frequency refers to the frequency of jitter (i.e., instability and fluctuations in data transmission or processing) in time series data or signals. This frequency is usually used to describe the repetitive pattern or periodicity of data jitter.

[0091] It should be further explained that, in a specific implementation process, the process in which the data analysis module simultaneously performs data analysis on vehicle data to be analyzed in a plurality of data analysis devices includes:

[0092] The synchronous analysis number of the data analysis module is set, and the synchronous analysis number is recorded as Y, where Y is an integer greater than 0. The data analysis module synchronously performs data analysis on the vehicle data to be analyzed in Y data analysis devices according to the synchronous analysis number Y;

[0093] The content of the data analysis is: setting a location range set corresponding to the location information in the vehicle data to be analyzed, a sensing standard set corresponding to the sensor data, and a communication standard set corresponding to the network communication data;

[0094] The position range set includes position information under several standard position ranges, the sensor standard set records the normal value ranges corresponding to the vehicle speed sensor data, steering sensor data, tire pressure sensor data, vehicle stability sensor data and engine speed sensor data under the normal state of the vehicle; the communication standard set records the normal value ranges corresponding to the vehicle navigation data and driving behavior data under the normal state of the vehicle;

[0095] When any one of the following conditions holds true: the location information in the vehicle data to be analyzed does not conform to the location range set, the sensor data does not conform to the sensing standard set, and the network communication data does not conform to the communication standard set, the analysis result of the data analysis on the vehicle data to be analyzed is: "The vehicle corresponding to the current vehicle data to be analyzed is in an abnormal state"; when the location information conforms to the location range set, the sensor data conforms to the sensing standard set, and the network communication data conforms to the communication standard set, the analysis result of the data analysis on the vehicle data to be analyzed is: "The vehicle corresponding to the current vehicle data to be analyzed is in normal state".

[0096] It should be further explained that, in the specific implementation process, the visualization sorting module sorts out the analysis results of several vehicle data to be analyzed and visualizes the analysis results, and the process includes:

[0097] The visualization sorting module obtains the analysis results of a plurality of vehicle data to be analyzed and performs data analysis, wherein the analysis results include "the vehicle corresponding to the current vehicle data to be analyzed is abnormal" and "the vehicle corresponding to the current vehicle data to be analyzed is normal";

[0098] The visualization sorting module is provided with a safe vehicle visualization display partition and an abnormal vehicle visualization display partition, and the vehicle information of all vehicles whose analysis results are "the vehicle corresponding to the data to be analyzed of the current vehicle is normal" is sorted and visualized in the safe vehicle visualization display partition, and the vehicle information of all vehicles whose analysis results are "the vehicle corresponding to the data to be analyzed of the current vehicle is abnormal" is sorted and visualized in the abnormal vehicle visualization display partition;

[0099] The vehicle information includes basic vehicle information, vehicle status information and vehicle parameter information;

[0100] The basic vehicle information includes vehicle brand, vehicle model and vehicle VIN code;

[0101] The vehicle status information includes a vehicle normal status where the analysis result is "the vehicle corresponding to the current vehicle data to be analyzed is normal" and a vehicle abnormal status where "the vehicle corresponding to the current vehicle data to be analyzed is abnormal";

[0102] The vehicle parameter information includes engine type, engine displacement, maximum power, vehicle body type and driving mode.

[0103] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
