Multi-network Access Platform Monitoring Terminal Design And Realization

The multi-network access platform not only supports the signal of GSM/TDMA/ TD-LTE and other networks coverage, but also provides RRU mode access to the desktop. The hardware structure is different from traditional repeater, so the repeater monitoring system can not meet the monitoring demands. Therefore a new system should be developed.The new embedded application software architecture is put forward based on ARM9 + Linux according to the design specification and advantages of many ordinary monitoring systems. The system's superiority of multi-task processing, real time, high speed and strong addressing ability is utilized fully, so the reliability and flexibility are improved.The system has been debugged with hardware and achieved all target and requirement. This system has passed the acceptance of user.The works of this thesis include 5parts in conclusion.1. After studying the repeater monitoring system's development status of domestic and oversea, the ARM + Linux embedded control system is designed according with the actual situation. This part of work includes designing the monitoring architecture and transplanting Linux to ARM9.2. After studying the framework of embedded system design, some common problems are found, such as low maintainability and poor scalability. So the design method is put forward combining layer processing of modules. This theory has been applied to process of analysis, design and implementation of the monitoring system. The maintainability and scalability of this system is well after testing.3. A new alarm processing mechanism strategies is put forward and realized according to the system's specification and practical application needs. The system has no false alarm and leakage alarm after one month of test running. The effectiveness of alarm system is verified preliminarily.4. The process of analysis and design is followed by the thought of software engineering.5. The complete multi-network access platform terminal monitoring system is built through 37 data structure.
