The invention provides a remote data acquisition method and device based on the Internet. The method comprises the following steps: a slave station sub-module generating a data slave station; the slave station sign-in sub-module being used for connecting the slave station sub-module to the transfer service module in the Internet; furthermore, after the real-time data service sub-module receives areal-time data query request from a master station service module in the Internet from the transfer service module through the slave station sub-module, corresponding real-time remote variable data can be queried according to a preset variable table, and sending the corresponding real-time remote variable data to the master station service module through the transfer service module. Visibly, eachfield terminal device is converted into the cloud data service slave station, for distributed data storage, so that when a master station service module at any position in the Internet has a data query requirement, remote data
