The invention relates to a high-precision Beidou positioning based universal automatic driving control device for agricultural machinery. The device comprises a GPS/BD (global positioning system/Beidou) positioning module, an intelligent controller and an agricultural machinery management platform server, and is characterized in that the GPS/BD positioning module is used for acquiring position information of vehicles, the intelligent controller is used for collecting and controlling operating parameters of an agricultural machinery system, the position information and the operating parameters of the agricultural machinery are uploaded to the agricultural machinery management platform server via a GPRS (general packet radio service) network, the sever makes decision on operating data of the agricultural machinery, and the intelligent controller realizes automatic driving control on the agricultural machinery according to the operating data. The automatic driving control device for the agricultural machinery effectively realizes control on automatic operation of the agricultural machinery through the acquired vehicle positions and operating parameters, the agricultural machinery can be automatically controlled to operate according to an set route, human input is reduced, and the automatic driving control device has significant advantages and is convenient to apply and popularize.
