Technical Field

Background
The software program in the controller is often provided with parameters capable of adjusting program functions to adapt to different controlled devices, so as to ensure that the controlled devices operate safely and stably. Because the parameters are required to be effectively stored in the RAM for a long time and are influenced by the characteristics of power-down volatile data of the RAM, the parameters are usually stored in the nonvolatile memory when the power is down, and the parameters in the nonvolatile memory are reset or restored to the RAM when the power is up.
The traditional parameter resetting method is mainly characterized in that parameters in the RAM are stored in an EEPROM in batches, check codes are generated by checking the parameters in the same batch, and the batch of parameters and the corresponding check codes are stored in the EEPROM, so that parameter initialization is carried out according to the comparison result of the check codes generated by secondary check parameters and the check codes in the EEPROM after the parameters are powered on, namely, parameter resetting is carried out when the check codes are inconsistent, and parameter recovery is carried out when the check codes are consistent. When the program is upgraded and new parameters are added, the new parameters are stored in the EEPROM corresponding to the new addresses, if the parameters are initialized, the addresses corresponding to the same batch of parameters where the new parameters are located are all reset, so that the parameters which are already set in the previous version are reset, if the addresses are initialized in the original version of the program, the new addresses are initialized, so that the new parameters cannot be normally reset to effective values, and the problem of initializing the new parameters for upgrading the program is difficult to solve.

Detailed Description
The technical solutions in the present invention will be described clearly and completely with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that, the step numbers in the text are only for convenience of explanation of the specific embodiments, and do not serve to limit the execution sequence of the steps.
As shown in fig. 1, the first embodiment provides a parameter reset control method, which includes steps S1 to S4:
and S1, reading the version number of the software program from the nonvolatile memory, and judging whether the nonvolatile memory stores the version number of the current software program.
S2, when the version number of the current software program is saved in the nonvolatile memory, calculating a version span between the version number of the current software program and the version number of the software program.
And S3, if the version span is larger than 0, resetting the parameters of the newly added parameters of the adjacent software programs between the current software program and the software programs, and storing all the parameters of the current software program in the nonvolatile memory.
And S4, if the version span is less than or equal to 0, storing all parameters of the current software program in a nonvolatile memory.
Non-volatile memory includes, but is not limited to, EEPROM, among others. An eeprom (electrically Erasable Programmable read only memory) refers to a charged Erasable Programmable read only memory, and is a memory chip with no data loss after power failure. The EEPROM can be erased and reprogrammed on a computer or a special device.
Illustratively, in step S1, when the current software program is powered on, the version number of the software program is read from the non-volatile memory, and it is determined whether the non-volatile memory stores the version number of the current software program by using the power-down memory of the non-volatile memory.
In step S2, when it is determined that the version number of the current software program is saved in the nonvolatile memory, the version number of the current software program is subtracted from the version number of the current software program to obtain a version span, so as to determine whether the current software program has been upgraded according to the version span.
In step S3, when the version span is greater than 0, it is determined that the current software program is upgraded, and only parameter reset is performed on newly added parameters of the adjacent software programs between the current software program and the software program, the current values of the newly added parameters are retained, the current values of the newly added parameters are modified to initial values, and after the parameter reset is completed, all the parameters of the current software program are stored in the nonvolatile memory.
In step S4, when the version span is less than or equal to 0, it is determined that the current software program is not upgraded, and it is only necessary to store all the parameters of the current software program in the nonvolatile memory without resetting the parameters of the current software program, and keep the current values of all the parameters.
In the embodiment, whether the nonvolatile memory stores the version number of the current software program is judged by using the power-down memory of the nonvolatile memory when the nonvolatile memory is powered on, so that when the nonvolatile memory stores the version number of the current software program, whether the current software program is upgraded is judged according to the version number of the current software program and the software span of the version number of the software program read from the nonvolatile memory, if the version span is greater than 0, the current software program is considered to be upgraded, only parameter reset needs to be carried out on newly-increased parameters of the adjacent software programs between the current software program and the software program, if the version span is less than or equal to 0, the current software program is not upgraded, the parameter reset does not need to be carried out on the parameters of the current software program, so that the set parameters can be reserved and the newly-increased parameters can be reset simultaneously under the condition of upgrading the software program, the error probability of the parameters is effectively reduced, and the safe and stable operation of the controlled equipment is ensured.

In the embodiment, all the parameters of the current software program are reset when the version number of the current software program is judged not to be saved in the nonvolatile memory, so that the parameters can be saved as initial values under the condition that the parameters of the software program are not saved, the error probability of the parameters is effectively reduced, and the safe and stable operation of the controlled equipment is ensured.
