The invention discloses an explosive type data caching and processing system for a SCADA system and a method of the explosive type data caching and processing system for the SCADA system. The system comprises a data receiving module, a file caching module, a data pre-reading module, an queue caching module, a data optimization module and a tread pool module, wherein the data receiving module receives a data storage request message sent by an application program and enables the data storage request message to be placed into a disk caching file or a caching queue of the file caching module according to a caching queue state, the data pre-reading module inserts a data storage request stored in the file caching module into the caching queue, the data optimization module reads the data storage request, optimizes the data storage request and then calls an idle thread in a thread pool to execute the data storage operation. The system and method can well solve the safety problem of data and the SCADA system when the massive data storage requests are submitted.
