Software version control method

The invention relates to a software automatic control method, in particular to the field of software version control, and discloses a software version control method. The software version control method includes the following steps: A, building a software mapping table with software numbers, module type numbers, module type version numbers and station information, and enabling the software mapping table to be stored in a database, B, enabling a system to read a serial number of a module and find the module type number and the module type version number corresponding to the module from the database according to the serial number, and C, enabling automatic control software to obtain the local station information, and determining the version number of software to be used from the software mapping table in the database according to the module type number, the module type version number and the station information. According to the software automatic control method, the software determining efficiency and accuracy is greatly improved, and the technical problem that the version of testing software is wrongly selected is solved.
