The invention relates to a UDP-based TDMA protocol control method and platform. The method comprises the following steps: S1, implementation of an Ethernet network drive design method; S2, implementation of a port data adapter design method; S3, implementation of a design method for control data caching; S4, implementation of a business data caching design method; and S5, modulation data adapter design method. In addition, the platform includes an integrated business processing module (1), an ATO core board module (2), and a frequency conversion board module (3), wherein the three modules are combined into one. According to the method, the method can be extended; a standard communication protocol interface can be met; and the transportability is high. On the basis of combination of the method and platform, the TDMA protocol function realization way is simplified; the modularization structural design is employed; and the hardware platform can be established based on the simple structure.
