Abstract: During the operation of the special wireless system TETRA (Terrestrial Trunked Radio) equipment in Metro Communication, periodic health checks of the system are required to ensure the stability of equipment performance and working state, or the faulty hardware should be replaced in timely manner if a device is faulty. In the above two operations, the status query, data configuration, status modification and other operations of the related equipment need to be carried out on TETRA network management. At present, TETRA network management operation skill training mostly adopts silent writing and drawing, which has the problems of single training mode and poor learning effect. Based on the actual maintenance and training needs of dedicated wireless, the technical personnel puts forward new ideas in the use of training tools, develops TETRA equipment training simulator based on python, which realizes the reality of training operation perception and greatly improves the training effect, and gradually realizes the goal of integrating innovation into metro skills training.

摘要： 地铁通信专业中专用无线系统陆上集群无线电（Terrestrial Trunked Radio，TETRA）设备在运行过程中，为保障设备性能和工作状态稳定，需要定期进行系统健康检查，或当某个设备出现故障时，需及时更换相关故障硬件。上述两种操作时，均需要在TETRA网管上对相关设备进行状态查询、数据配置、状态修改等操作。目前TETRA网管操作技能培训多采用默写默画，存在培训方式单一、学习效果差等问题。基于专用无线实际维保和培训需求，技术人员在培训工具使用方面提出新设想，基于Python开发TETRA设备培训模拟器，实现培训操作感知真实化，大幅提升培训效果，逐步实现把创新融入地铁技能培训的目标。
