Abstract: Aimed to the current remote monitoring system doesn’t effectively support the production and management modes in distributed network architecture，a distributed remote monitoring system based on middleware is proposed.This system doesn’t depend on specific hardware and software platform and the mechanical equipments can dynamically entry or exit the system.Firstly，the framework and safety design of remote monitoring system are introduced.Specially，the four mechanisms and realization technologies of lookup server which is the key for realizing distributed architecture are proposed.Moreover，the communication scheme of this system is discussed.This system can improve the maintenance efficiency and lay a foundation for application and population of remote monitoring system.
