According to the invention, a GPS-based distributed terminal parameter data processing method and system are designed for the characteristics of wide distribution and a large number of IOT (Internet of Things) and IOV (Internet of Vehicles) terminals. A control center conducts distributed centralized management of terminals distributed in multiple areas through the DTPSP. A DTPSP uplink packet containing GPS information is sent when the terminals are connected to the control center. The control center analyzes the DTPSP uplink packet, and according to a GTDA algorithm, obtains and stores a terminal topology table, terminal numbers and other terminal parameters into a database. Then, the terminal numbers, the other terminal parameters and the terminal topology table are packed into a DTPSP downlink packet and sent to the terminals. After receiving the DTPSP downlink packet, the terminals conduct data analysis and then obtain the terminal numbers and other configuration parameter data for automatic update of local configuration parameters. The multi-area and multi-terminal intelligent automatic configuration management is realized without manual participation.
