The invention provides a database automatic generation method and device based on an electronic map and IO driving and acquisition information. The method comprises the steps of: traversing an acquisition information sub-table in an IO driving and acquisition information table, and storing each data of the acquisition information sub-table into a first mapped data table; traversing a driving information sub-table in the IO driving and acquisition information table, and storing each data in the driving information sub-table into the first mapped data table; traversing each sub-table in the electronic map, which is related to a code bit, and storing each data in each sub-table into a second mapped data table; and traversing the first mapped data table, carrying out equipment name matching on the data in the first mapped data table and the second mapped data table, merging key values in the first mapped data table into key values in the second mapped data table, which have matched equipment names, and storing the data in the second mapped data table into a database. According to the database automatic generation method and device provided by the embodiment of the invention, an effect of automatically integrating the data into one database file is achieved.
