In order to break through the control mode of remote control system of X-ray single crystal diffraction, in which upper computer positive controls lower computer, the enterprise-class RabbitMQ message queue server is used to act as control communication server to build a messaging platform for X-ray single crystal diffraction remote control system. And we have achieved the remote operation and control among various distributed subsystems. The paper mainly introduces the design of the communication system for remote control system and the primary testing shows this communication architecture can realize stable and precise messaging.
