2. The method for processing automobile historical signal data according to claim 1, characterized in that: The obtaining of the backend return data and the classification and analysis of the backend return data include: Calling the data processing module to process the braking force data, driving force data, voltage value and temperature value; Convert the timestamps of the reporting time and the receiving time into a standard string time format, and obtain the braking force and the driving force data based on whether the background return data contains the gears attribute; if the background return data contains the gears attribute, obtain the braking force and the driving force data as Data.gears; Determine whether the voltage value and the temperature value exist in the background return data; based on whether the voltage value and the temperature value exist in the background return data, separate them into arrays with commas, retain three decimal places respectively, and splice the units V and ℃.

3. The method for processing automobile historical signal data according to claim 1, characterized in that: The distinguishing abnormal and invalid data based on the data basic information and processing the abnormal and invalid data includes: Calling a formatted data method to process the data according to the attributes of the basic data information; Among them, first determine whether the attribute of the basic information of the data has a between attribute, then determine whether the data is within the valid interval, and finally concatenate the prefix and unit of the data; Determine whether the attribute of the data basic information has a convert attribute, and call the custom convert method to perform custom calculations; Determine whether the attribute of the basic data information has a symbol attribute, and splice the units of the data; Determine whether the attributes of the basic data information have the compose attribute. First, split the data into an array and traverse it. Then, use each item as a key to obtain the value corresponding to the map attribute. Finally, use the symbols defined by compose to splice it into a string. Determine whether the attribute of the data basic information has a map attribute, and obtain the value corresponding to the map array; If the above judgments are all negative, the initial value is returned.
