[0041] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] The method for storing automobile meter mileage data according to a preferred embodiment of the present invention is as follows: Figure 1 As shown, the method for storing automobile instrument mileage data includes the following steps:

[0043] Step S10: acquiring storage format information of a memory and mileage data of a target vehicle, constructing a plurality of data format information according to the storage format information, and dividing a plurality of storage spaces in the memory.

[0044] The data format information includes: frame header information, mileage data information, checksum information, frame validity status information and frame tail information. Different data formats can be used to determine the validity of mileage data to prevent mileage data errors; and multiple storage spaces can also ensure that when mileage data is abnormal, the current mileage data can be restored from different storage spaces to improve data stability and accuracy.

[0045] Specifically, storage format information of a memory and mileage data of a target vehicle are obtained, wherein the storage format information is set by a user and then input into the memory; according to the storage format information, the frame header marking information, the mileage data information, the check information, the frame valid status information and the frame tail marking information are constructed; according to the storage format information, a plurality of storage spaces with a preset number of bytes are divided in the memory, wherein the storage space includes a first storage space and a second storage space with the same number of bytes.

[0046] Among them, the mileage data is stored in the FLASH (flash memory) inside the MCU (Microcontroller Unit). The FLASH has an encryption protection function. After the encryption processing of external read-write data lock protection, the MCU can store and read the internal FLASH data normally, while the external device cannot read and write the internal FLASH data. In this way, the external device cannot crack the mileage data by reading the FLASH data, or modify the mileage data by rewriting the FLASH data. This process ensures the security of the mileage data.

[0047] Step S20: construct a variety of data according to the mileage data and the data format information, and store the mileage data and all the data in all the storage spaces respectively.

[0048] Specifically, based on the mileage data and the frame header identification information, the frame header identification data of the mileage data is constructed; based on the mileage data and the verification information, the verification data of the mileage data is constructed; based on the mileage data and the frame validity status information, the frame validity status data of the mileage data is constructed; based on the mileage data and the frame end identification information, the frame end identification data of the mileage data is constructed; the mileage data, the frame header identification data, the verification data, the frame validity status data and the frame end identification data are copied to obtain corresponding backup data; the mileage data, the frame header identification data, the verification data, the frame validity status data and the frame end identification data are saved in the first storage space, and the backup data is stored in the second storage space.

[0049] The backup data includes: backup frame header marking data, backup mileage data, backup check data, backup frame valid status data and backup frame tail marking data. The corresponding backup data is consistent with the content of these data and is saved in the second storage space. It can be used to restore the mileage data when the mileage data is abnormal, thereby improving the integrity and reliability of the data.

[0050] Furthermore, the frame header marking data indicates the beginning of a storage unit data, the mileage data is the data that actually needs to be stored, the verification data is the comparison data generated by the mileage data through the verification algorithm, the frame valid status data indicates whether it is the current mileage data or the historical mileage data, and the frame tail marking data indicates the end of a storage unit data. This data format can judge the validity of the mileage data, prevent errors in the mileage data, and improve the accuracy of the mileage data.

[0051] Step S30: When the mileage data is updated, all the data are updated in real time, and the updated current mileage data is stored in all the storage spaces respectively.

[0052] Specifically, the updated current mileage data is obtained, and according to the current mileage data and the data format information, the current frame header marking data, the current verification data, the current frame valid status data and the current frame tail marking data are constructed; the current mileage data, the current frame header marking data, the current verification data, the current frame valid status data and the current frame tail marking data are copied to obtain the current standby frame header marking data, the current standby mileage data, the current standby verification data, the current standby frame valid status data and the current standby frame tail marking data; the current frame header marking data, the current mileage data, the current verification data, the current frame valid status data and the current frame tail marking data are saved in the first storage space; the current standby frame header marking data, the current standby mileage data, the current standby verification data, the current standby frame valid status data and the current standby frame tail marking data are stored in the second storage space.

[0053] Among them, when the mileage data is updated in real time, the mileage data and its backup data are saved once. For example, in units of 0.1 kilometers, the mileage data and backup data are saved every time the mileage data increases by 0.1 kilometers to prevent the current mileage data from being lost when there are abnormal external conditions (such as power supply interruption), and the valid state bit of the mileage data frame of the previous frame is changed to an invalid state, and it is marked as historical mileage data, independent of the current mileage data and backup mileage data.

[0054] Furthermore, the time of copying the spare mileage data stored in the second storage space is obtained, and the spare frame header marking data, the spare check data, the spare frame valid status data and the spare frame tail marking data corresponding to the spare mileage data are sorted according to the time to obtain sorting information; when an abnormality occurs in the mileage data stored in the first storage space, the spare data in the second storage space is obtained, and the spare frame header marking data, spare mileage data, spare check data, spare frame valid status data and spare frame tail marking data corresponding to the abnormal mileage data are overwritten into the first storage space.

[0055] Among them, when the instrument is powered on, the MCU searches the mileage data frame saved in the internal FLASH area, finds the last valid frame of the mileage data frame, compares it with the data in the backup area, and when the mileage data is consistent, it is normal data, and obtains the current frame address and mileage data. If the data in the mileage data storage area is abnormal (for example, caused by a power supply interruption), and no valid frame is found, the mileage data in the backup area (including spare frame header marking data, spare mileage data, spare check data, spare frame valid status data, and spare frame tail marking data) is used, and the mileage data in the mileage data storage area is corrected. If the data in the backup area is also abnormal (for example, caused by a power supply interruption), the historical mileage data can be used to restore the current mileage data through a chronological sorting method, which further improves the security and reliability of the mileage data and avoids data loss.

[0056] The present invention selects a memory with an encryption protection function and stores the mileage data in a preset format, thereby ensuring the correctness and reliability of the mileage data, and when the mileage data is abnormal, the current mileage data can be restored from the stored data, thereby improving the reliability and security of the automobile instrument mileage data.

[0060] The data updating module 53 is used to update all the data in real time when the mileage data is updated, and store the updated current mileage data in all the storage spaces respectively.
