The network control system for atmospheric detection equipments consisted of the master control computer, the control machines to the atmospheric detection equipments and the network switch. This system applied Windows Socket to achieve the communication and selected the asynchronous communication mechanism to avoid the occurrence of the block. The message package format was designed in detail aimed at the specific requirements of this system and XML was employed to unify the various formats of the data measured in each control machine. Finally this system achieved the centralized control of the atmospheric detection equipments and the centralized access to a variety of atmospheric parameters.
