摘　　要：为提高通信双方数据传输效率,确保传输安全,提出基于线程池技术的空间数据同步传输方法仿真。根据空间数据传输系统结构确定系统工作流程;采用线性池技术将其分为主线程、管理线程、工作线程与查询线程四个逻辑单元,分配每个单元承担的任务;计算线程池数量同步任务列表,明确主线程工作进度构建同步传输处理逻辑时序图;引入空间数据加密同步算法选择最佳传输路径;分别生成接收双发的密钥机制和结合认证码,实现空间数据同步安全传输。仿真结果表明,所提方法可减少传输时间,减少接收延时,保障空间数据安全。In order to improve the efficiency of data transmission and ensure the safety of transmission, a simulation method of synchronous transmission of spatial data based on thread pool technology is proposed. Firstly, according to on the structure of spatial data transmission system, the workflow of the system was determined;Using linear pool technology, divide the workflow was divided into four logical units: main thread, management thread, work thread and query thread, and each unit was allocated the tasks. Then, the synchronization task list of the number of thread pools was calculated to determine the work progress of the main thread, and the sequence diagram of synchronization transmission processing logic was constructed. The synchronization algorithm of spatial data encryption was used to select the best transmission path. At last, the key mechanism and the combination authentication code were generated, achieving the synchronous and secure transmission of spatial data. The simulation results show that the method can reduce the transmission time and the receiving delay, and ensure the security of spatial data.
