The project is designed for astronomy project from Academy of Sciences. The station antenna class monitor system is a large part of the monitoring system of the whole. The station antenna control system fulfills the monitoring task related to antenna and all of the astronomy equipments. The realization of network communication by Indy(Internet Direct) technique is discussed. A bottom core frame module is developed, which is irrelevant to the control project; on this basis, each logic module is designed. The design method of the logic part of the station antenna monitor system is presented in detail, as well as the implementation strategies of automation process. The proposed system has been put in use for almost one year with a good performance.
