轰炸光电瞄准主控计算机系统硬件设计

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硬件设计问题,本文针对最小系统模块、电源模块和通信模块三大部分,采用CPLD实现1553B的RT模式,通过将1553B通信模块集成到主控计算机板块上,实现了轰炸光电瞄准主控计算机系统硬件设计。结果表明,采用状态机设计思想提高了CPLD程序开发效率,减小了成本,缩短了开发时间、减小了风险,同时合并了系统结构、缩小了控制箱体积。

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 hardware design of master control computer on bombing electro-optic targeting system, with minimum system module, power supply module and communication module parts, RT model of 1553 B is realized by using CPLD. By 1553 B communications module integrated into the master control computer plate, the hardware design of bombing electro-optic targeting master computer control system was done. The results show that the design of state machine can improve the CPLD application development efficiency, reduce the cost, shorten the development time and reduce the risk, and consolidate the system structure, reduce the volume control box.
