Since the model is a large scale and NP-hard combinational optimization problem in the real navigation environment, a hybrid simulated annealing algorithm is employed to search the suboptimal solution composed of a lockage timetable and a ship scheduling, The search starts by trimming the existing lockage timetable based on heuristic rules; the result is then used to compute the ship scheduling by the depth-first-search algorithm. The obtained solution is finally updated by the Metropolis rule.

本文首先提出了该问题的混合整数非线性规划模型，在实际通航调度环境中，该模型属于强NP-hard复杂度的大规模组合优化问题，因此设计了一种混合模拟退火算法来搜索次优化调度方案，该算法将解分解为闸次时间表和船舶调度计划两部分，在搜索过程中用启发式规则对闸次时间表进行调整，然后用深度优先搜索算法根据闸次时间表求解船舶调度计划，最后根据Metropolis规则对当前解进行更新。

The SINS of FOG is designed and implemented based on DSP. The system is with a dual CPU structure. DSP is used to process data while MCU controls data acquisition and the communication between DSP and MCU is achieved by dual-port RAM. All of these constitute a small strap-down navigation system. Meanwhile introduced a kind of algorithm of SINS, SPI communication and the second boot Loder of TMS320C6713 in briefly. After testing, the system speed and accuracy satisfy design requirements and the system has been applied to actual system.

介绍了一种基于DSP的光纤陀螺捷联惯导系统的设计与实现方法；系统采用DSP+MCU的体系结构，DSP主要完成导航计算，利用单片机实现对数据采集模块的控制，并通过双口RAM实现单片机和DSP的数据通信，构成了一套小型捷联惯导系统，同时给出了一种捷联惯导算法编排，简要介绍了SPI通信和TMS320C6713的二次bootloder方式；经测试，系统速度和精度都满足了设计要求，已应用于实际系统。

Currently there are two kinds of radio navigation resources in our country. One is the Changhe Ⅱ loran, which mainly overlays inshore regions of our country and serves for ships. The advantages of this system include the strong transmitting power, the wide overlaying region, and simple receiving technique.

我国目前现有的无线电导航资源有两种：一个是"长河二号"无线电远程导航系统，主要覆盖我国近海区域，主要为舰船提供导航，该系统发射功率大，覆盖广，接收技术简单，其缺点是导航精度低，在两个台链的结合部会出现盲区。
