摘　　要：为了实现地理空间数据的共享与整合,充分反映地理空间分布特征信息,提出面向空间信息光网络的宽带无线微波接入控制。首先通过空间信息光网络原理及模型,把自然连通系数作为网络抗毁性衡量准则,并建立抗毁性优化模型以保证网络数据安全;其次引入微波接入互操理念,提出基于IAVB的节能调度方法,改善虚拟突发的结束条件,防止未正确终止虚拟突发产生的能量损耗;最后采用协议测试法构建宽带无线微波接入控制方法,达到空间地理位置信息及时共享与高效率信息传输目标。仿真结果表明,所提方法能够完成各种复杂环境下的地理数据交互,为空间数据的良好交互提供有效帮助。Broadband wireless microwave access control for spatial information optical network is presented in this paper, in order to share and integrate geospatial data and better reflect geospatial distribution characteristic information. Firstly, according to the principle and model of spatial information optical network, based on the measurement criterion of network survivability(natural connectivity coefficient as the criterion), the survivability optimization model was established for the security of network data. Secondly, the concept of microwave access interoperability was introduced to propose an energy-saving scheduling method based on IAVB, improving the end conditions of virtual burst and prevent the energy loss caused by incorrect termination of virtual burst. Then, the protocol test method was applied to found a broadband wireless microwave access control method. At last, the goal of timely sharing of spatial geographic information and efficient information transmission was completed. The simulation results show that this method can complete geographic data interaction in various complex environments and is beneficial to spatial data interaction.
