英文摘要	The invention relates to a multi-message convergence transmission method for field level industrial wireless network, comprising the following steps: the field level industrial wireless network formed by combining star configuration and reticular structure is constructed; a convergence object is constructed in the field level industrial wireless network, and the convergence period of the convergence object is allocated; a de-convergence object is constructed in gateway equipment; application data is collected by field equipment in the field level industrial wireless network according to requirements, and the message containing the application data is sent out; the convergence object in route equipment collects and caches the message containing the application data in the convergence period and carries out convergence treatment, so as to form the converged message. The route equipment transmits the converged message to the de-convergence object of the gateway equipment, and the de-convergence object caries out de-convergence treatment to the converged message, and the de-converged messages are transmitted to the corresponding user application program respectively; under the condition of transmitting the application data with the same amount, the nameplate communication overhead is reduced, and the wireless message quantity needed to be used is greatly reduced.
