The Architecture Design Of Radio Monitoring Station And Research On Related Key Technologies

The rapid development of radio technology has brought severe challenges to radio supervision.In response to increasingly complex radio management issues,our country has formulated a series of relevant standards for radio monitoring and management,and carried out the construction of integrated radio management platform.The radio monitoring station is the terminal equipment in this platform as well as the carrier for implementing the radio monitoring service.Based on development experience and related materials,this paper has done some research on radio monitoring stations,including the following contents:(1)Analyze the radio monitoring service and its corresponding requirements.Based on the 6 types of monitoring station models proposed in related documents,the concepts of radio monitoring station function set and hardware set are given.On the basis of these concepts,the logical structure and layered architecture model of the monitoring station are proposed.(2)Provide a network transmission solution based on the logical structure of the monitoring station,corresponding to the transmission layer and the communication layer.By adding industrial personal computer as an intermediary,the heterogeneity of the hardware unit and the main control platform is solved.On this basis,this paper analyzed the problems of pack and unpack in data transmission,low data interaction efficiency,and undetectable disconnection in some cases,then gave the solutions of these problems.Based on the network framework used in the main control platform,data transmission with the control system of the radio monitoring station is analyzed and realized.(3)Analyze the core layer in the layered architecture—business layer.Provides a solution to the low resource utilization during the business processing of monitoring stations,that is,the implementation of ‘parallel calculation based on operation dispatch'.To describe this scheme,the concept of ‘component atomic operation' is first proposed to encapsulate and abstract the physical layer and the transport layer below the process layer.On the basis of component atomic operations,data processing operations are further proposed,and a business execution process based on those operations and operation dispatch is given.Based on the business execution process,the design of the business pool is given,and finally the calculation parallel mechanism based on operation dispatch is realized.On the basis of this mechanism,business execution efficiency analysis and scheduling strategy design and analysis are carried out,and finally the effectiveness and universality of this scheme are proved through experiments.
