Large-Scale Network Evaluation System FC-807

The main idea of a large-scale network evaluation system is to build a system that combines software and hardware in a laboratory environment, and simulate working scenarios in a real environment through hardware connections, such as the attenuation of ground objects on wireless signals, and the electromagnetic environment. Wave interference to wireless signals, etc.; through the software operation to set the size and proportion of these attenuation and interference, so as to simulate the working status of the wireless collection system in different complex environments, and find and analyze the deficiencies in the system, so as to improve the system and The performance improvement of the node and the improvement of the interconnection agreement provide a scientific basis.

• 1. The simulation and evaluation software can automatically compose protocol standard messages, analyze messages, automatically realize the integrated rapid test and analysis process, store test data in real time, and support traceability. The export of the test report is automatically completed, and the format can be EXCEL or WORD document, etc. The report design adopts the unified data format stipulated by the State Grid Provincial and Municipal Electricity Company.
• Adopt open source and free design language and its development platform to avoid copyright and other issues.
• 2. In terms of data management, Hibernate modules should be used, and at least lightweight small and medium-sized MySQL databases should be used. It supports complete data backup and recovery, fault tolerance and other mechanisms to meet the functional requirements of large-capacity data storage, retrieval, and mining. Database design should fully consider the expansion of information. The use of relational databases should try to meet the requirements of the third paradigm of database design. Those that cannot be achieved should have sufficient reasons and be stored together with the data dictionary in the form of documents.
• 3. The verification system should have an alarm function, and it should be able to give an alarm in time for abnormal conditions in the operation link, especially those that affect the safety of personnel and equipment.
• The alarm information is subject to hierarchical control, which should include at least information such as the type of fault and the location of the fault point, and the alarm level and type shall be distinguished by different colors.
• The alarm interface should be able to pop up automatically immediately.
• 4. Use a consistent style of operation interface, reasonable layout, simple and clear window content, and easy-to-understand, consistent and consistent information language.
• The display screen should be organized in a hierarchical structure or a tree structure according to the process. The operator should not click more than five times to call any screen, and important functions can be called out by one key.
• Realize the visual display of animation simulation screen, configuration screen, fault information, etc., real-time display of the status of all devices of the current unit, so that operators can grasp the operating status of the equipment in real time.
