Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, a vehicle internet terminal TBOX includes: a communication module: the data channel is used for carrying out real-time transmission of data between the vehicle-mounted internet terminal TBOX and the remote server; a positioning module: positioning the vehicle to obtain positioning real-time data; CAN data communication module: the method comprises the steps of forwarding an instruction from a remote server to an electronic control system (ECU) of the vehicle, collecting ECU data of the electronic control system of the vehicle, and feeding the ECU data back to a vehicle-mounted internet Terminal (TBOX); the first acquisition unit is used for acquiring local RTC time of the vehicle-mounted networking terminal TBOX in real time and matching the local RTC time with a first timestamp for ECU data of the electronic control system; the second acquisition unit is used for acquiring the server time of the remote server in real time and matching the positioning real-time data with a second timestamp through the server time; a storage module: and the electronic control system ECU is used for storing the data matched with the time stamp and the positioning real-time data.
The invention provides a vehicle-mounted internet terminal TBOX, which CAN invade the interior of an electronic control system ECU of a vehicle to obtain the realization state data of each electronic control system of the vehicle and realize effective storage so as to facilitate the tracking and positioning of subsequent historical data or abnormal conditions, wherein the ECU is arranged at the positions of an engine, a transmission, an ABS, braking force and driving force distribution control and the like, the data acquisition is not real-time and is realized according to the instruction of a remote server, in the specific implementation process, in the initialization process of the vehicle-mounted internet terminal TBOX, the types, IDs and required data types of all ECUs connected with the vehicle-mounted internet terminal TBOX through a CAN data communication module need to be obtained, the contents of the parts are also used as instruction contents, and the link information of the remote server also needs to be obtained, and the link information comprises the IP address and the website of the remote server, in the method, corresponding instructions are processed through ID matching in the instructions, and corresponding data in any ECU can be acquired through the remote server, so that the versatility of the vehicle-mounted internet terminal TBOX is increased.
In the invention, data are transmitted between the vehicle-mounted networking terminal TBOX and the remote server, so that in order to improve the time accuracy of the stored data, improve the sensitivity of equipment and reduce the influence of network signal problems as much as possible, the accuracy of the data timestamp is ensured by the local RTC time and the server time respectively, so that the tracking and positioning of historical data or abnormal conditions are more accurate.
As a preferable example of the above embodiment, as shown in fig. 2, the time calibration module includes: a data extraction unit: in the implementation, it is emphasized that the simultaneity of data entry must be ensured to make the following steps meaningful; a calculation unit: comparing the first time stamp and the second time stamp which are acquired simultaneously, and calculating a difference value of the first time stamp and the second time stamp as a first time difference value, wherein the first time difference value represents the deviation of the local RTC time and the server time; an acquisition unit: acquiring network time of a mobile communication network or acquiring GPS time of a GPS under set conditions, wherein the set conditions are described in the following; a correction unit: as shown in fig. 3, when the first time difference is smaller than a first set threshold, it indicates that the deviation between the local RTC time and the server time is small, the first set threshold may take a value of 1-3 s, in this case, the first timestamp and the second timestamp are respectively reserved, and when the historical data is traced, the data in the time range may be considered to be corresponding.
When the first time difference value is greater than or equal to a first set threshold value and smaller than a second set threshold value, the intermediate time of the first time stamp and the second time stamp is taken as a correction time stamp, and the first time stamp and the second time stamp are respectively replaced, wherein the difference value between the first set threshold value and the second set threshold value is preferably 4-8 s, in this case, the deviation between the local RTC time and the server time is slightly larger, but the two values have mutual reference significance, and the reference significance is shown in that the two values can show that the deviation of the other side relative to a standard value of the time is still within a certain range, so that the time stamp can be considered as the correction standard value of the time, and the standard value can be considered to have certain error, but the error is controllable.
When the first time difference is larger than or equal to a second set threshold, whether the standard value is still within a controllable error range needs to be determined through external reference, at this time, the middle time between the first time stamp and the second time stamp is also taken as a correction time stamp, the network time or the GPS time is acquired through the acquisition unit, the correction time stamp is compared with the network time or the GPS time to obtain a second time difference, when the second time difference is smaller than a third set threshold, the standard value of the time still has reference, the first time stamp and the second time stamp are respectively replaced through the correction time, when the second time difference is larger than the third set threshold, the deviation of the set standard value of the time relative to the external reference is larger, the standard value cannot be used directly, at this time, one of the first time stamp and the second time stamp, which is closer to the network time or the GPS time, is taken to replace the other one of the first time stamp and the second time stamp, therefore, the data stored at the same time artificially have the same time stamp, the correspondence in the subsequent historical data application process can be ensured, and the uniform time stamp is close to the external reference, namely network time or GPS time, and has relative accuracy.
As a preference of the above embodiment, the storage module includes: a Flash storage unit: storing ECU data of an electronic control system; a ferroelectric memory cell: and storing the positioning real-time data. Data needing to be stored in real time are stored in high-speed ferroelectrics, but the data of the electronic control system ECU which is not stored in real time are stored in Flash which is relatively low in speed, the storage structure is optimized, the storage efficiency is improved, important data are subjected to double backup, and the safety of the data is improved.
In the implementation process, the maximum connection times for connecting the mobile communication network or the GPS is set, and when the connection is still unsuccessful after exceeding the maximum connection times, the vehicle-mounted internet access terminal TBOX is initialized, so that the program of the equipment returns to the original state to solve the problem of incapability of connection.
The server time and the body RTC time both have the situation of larger error, when the server time and the body RTC time deviate towards the same side, the second time difference value is possibly larger than the first time difference value, and the network time or the GPS time is relatively accurate, therefore, when the situation occurs, the matching of the corresponding timestamp is carried out by replacing the local RTC time and the time with larger deviation with the network time in the server time by the network time or the GPS time, namely, the situation that the timestamp is matched for the ECU data or the positioning real-time data of the electronic control system through the network time or the GPS time is allowed to occur, thereby overcoming the problem of integral time deviation of the data caused by the same side deviation; of course, this condition is temporary and will resume after the second time difference has decreased.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
