Design and Testing for Fast 50 Meters Model Main Reflector Communication Network

FAST 50 meters model is the scale model of FAST, the reflector surface deformation is taken actively, called the main reflector. In the processing of the FAST reflector spherical surface become paraboloid, contrast to existing communication networks, we propose to achieve control data by ethernet communication transmission. Before the experiment at Miyun, we design and test the communication networks with ethernet. 131 control nodes of Miyun model reflector are partitioned. The corresponding topological structure is designed and the packets loss in deferent time periods is tested. The results show that the communication network is consistent with the communication ability for FAST main reflector surface control network.
