The invention provides a wireless transmission simulation method and a simulation platform based on an Ethernet technique. The wireless transmission simulation method and the simulation platform based on the Ethernet technique comprise a signal sending processing method and a signal receiving processing method. The simulation platform comprises seven parts namely, a front panel (1), a circuit module (2), a port module (3), a power module (4), a back cover plate (5), a shell body (6) and an upper cover plate (7), wherein the power module (4), the circuit module (2) and the port module (3) are arranged in the shell body (6) in sequence from front to back and are combined into a whole together with the front panel (1), the back cover plate (5) and the upper cover plate (7). When the wireless transmission simulation method and the simulation platform based on the Ethernet technique work, the simulation platform is arranged in a system as is shown in picture 1 and is divided into three circuits: a first circuit is a terminal computer and an Ethernet interface 1; a second circuit is an Ethernet interface 2 and an analogue communication network; a third circuit is a supervisory computer and an Ethernet interface3, and parameter management and allocation of the simulation platform are carried out under the uniform control of the circuit module (2). The wireless transmission simulation method and the simulation platform based on the Ethernet technique have the advantages of being quick in access, simple and convenient to operate, reliable in work, high in cost performance and the like.
