轰炸光电瞄准主控计算机系统软件设计

Software Design of Master Control Computer on Bombing Targeting System

我军现役主战轰炸机均未配备光电瞄准系统,其轰瞄设备为纯光学目视老设备,夜间及复杂气象条件下无法观测目标,不能完成精确轰炸,需要配备光电瞄准系统;主控计算机系统设计为目前轰炸光电瞄准系统实现过程中待研究的关键技术;为解决轰炸光电瞄准主控计算机系统的软件设计问题,采用分层设计思想,设计了应用程序层、操作系统层和板级支持包(BSP)组成的主控计算机软件结构;采用自顶向下的设计思想,设计了基于ARM-VxWorks实现方案的性能稳定、较为成熟的主控计算机系统软件;结果表明用这种方案实现轰炸光电瞄准系统主控计算机,缩短了开发时间、减小了风险,可以提高开发效率,能够满足军用计算机实现方案的要求。

Bombers in our army have not been equipped with the Electro--Optic Targeting System （EOTS）, which cannot observe targets at night and as a result cannot conduct precise bombing with the all optic targeting systems as their bombing targeting systems, so the EOTS is needed. The master control computer design was one of the critical technologies in the realization of electro--optic bombing targeting systems. For the software design of master control computer on bombing electro optic targeting system, using hierarchical design, a master computer software structure consisting of application layer, operating system, and the board support package （BSP） was designed. With the idea of top--down design, the scheme of the master computer system software design based on ARM -- VxWorks is found to be stable performance and relatively mature. Results show that this scheme can be used to implement on master control computer of bombing electro-optic targeting system, shorten the development time and reduce the risk, and the efficiency of development can also be improved. The requirements of military computer implementation scheme will be able to meet.
