First, a hardware environment to which the method of the embodiment of the present invention is applied will be schematically described.
As shown in fig. 1, fig. 1 is a hardware connection scheme of a microprocessor operation log storage method of a vehicle-mounted terminal.
And the microprocessor of the vehicle-mounted terminal is connected with the main processor through a USB interface (or a serial port, an SPI interface and a CAN interface). And the running log of the vehicle-mounted terminal is sent to the main processor through the USB interface, and the main processor is responsible for storing and maintaining the running log. The main processor can also send instructions to the microprocessor through the USB interface to control log output, including the output type and output frequency of the log.
The embodiment of the invention discloses a method for storing an operation log of a microprocessor of a vehicle-mounted terminal, which is shown in figure 2 and comprises the following steps of 200-204:
200. the log file storage area of the main processor is checked.
In the embodiment, the log file of the microprocessor is stored in the log file storage area of the main processor, so that the storage area of the main processor of the vehicle-mounted terminal is effectively utilized.
In the main processor log file storage area, the log files are stored in a fixed format. For example, in text format: *. log files are stored for easy searching. In addition, the name format of the log file may include a date field to facilitate recognition of the generation date of the log file in the subsequent steps, for example, mcu _20200904.log, which represents that the log file is generated for 9, 9 and 4 days in 2020.
Taking the current date as 2020, 9, month and 20 as an example, first, whether a log file corresponding to the date field of 200920 exists in the storage area is searched. And if not, executing the step of subsequently creating the log file.

The preset number may be set according to actual requirements, for example, 1000.
It should be noted that in this embodiment, the number of the stored log files is determined after determining that there is no log file on the current day, instead of determining the number of the stored log files after creating a new log file, so as to avoid that the new log file exceeds the rated space of the storage area, which further causes storage failure.
202. And creating a log file of the current day.
Taking the current day as 2020, 9, 20 as an example, the newly created log file is mcu _20200920. log.
203. And deleting at least one log file stored in the previous time, and then creating a log file of the current day.

Correspondingly, the log data of the microprocessor in the two time periods are stored in the log file of the current day.
In another usage scenario, the car is continuously driven from 6 pm on the first day to 4 am on the second day, and although the in-vehicle terminal is continuously operating for a period of time, the period of time spans two days. Correspondingly, two log files are generated in the vehicle-mounted terminal, and microprocessor log data from 6 pm to 12 pm on the first day and microprocessor log data from 12 pm to 4 pm on the second day are respectively stored.
The method for storing the microprocessor running log of the vehicle-mounted terminal provided by the embodiment of the invention checks the log file storage area of the main processor, deletes at least one log file with the earlier storage time when judging that the stored log files reach the preset number under the condition of determining that the daily log files do not exist, and then newly establishes the daily log file so as to effectively utilize the storage space of the main processor to store the microprocessor running log and ensure that the daily microprocessor log data is stored in the newly established log file.

In this embodiment, in the log file storage area of the main processor, the log files are all stored in a fixed format. For example, in text format: *. log files are stored for easy searching. And the name format of the log file may include a date field to facilitate the recognition of the generation date of the log file in the subsequent steps, for example, mcu _20200904.log, which represents that the log file is generated for 9/4/2020.
In the embodiment, the date field is added in the name of the log file, so that the identification and management are facilitated. By looking up the date field of the log file in the storage area, it can be determined whether the log file of the current day exists in the storage area.
303. And judging whether the number of the stored log files reaches a preset number, if not, executing a step 304, and if so, executing a step 305.
In this embodiment, the preset number may be set according to actual requirements, or may be determined according to the actual size of the storage area, for example, set to 800, 1000, and the like.
304. And creating a log file of the current day.
Taking the current day as 2020, 9, 20 as an example, the newly created log file is mcu _20200920. log.
