WFST telescope is a large-aperture sky survey telescope jointly built by the University of Science and Technology of China and Purple Mountain Observatory. It is currently the most powerful optical time-domain sky survey telescope in the northern hemisphere. Its scientific goals are diverse, and the urgency and observation window period of different scientific tasks are different. During the observation period, the control of equipment requires accuracy, real-time, efficiency and safety. Therefore, we design and implement the OCS (Observatory Control System) of WFST which performs multi-layer abstraction on each hardware device and puts more attention on the operation of the observation process and the scheduling of observation tasks. In order to ensure the safety of equipment during the observation process, the OCS introduces a weather alarm system and fault diagnosis system. At the same time, we design an observation strategy system in the OCS to adjust the observation plan based on task priority, equipment information and meteorological information to maximize the efficiency of sky survey.
