Design of Armored Vehicle Three Defense System Controller

装甲车作为战时使用量最大的装备之一,其核、生、化防护问题自然受到特别重视。基于ARM7内核的嵌入式三防系统控制器硬件主要包括微处理器LPC2294、开关输入接口芯片MC33993、开关输出芯片MC33996、D/A转换芯片TLV5636、A/D转换芯片AD7476、CAN收发器MAX3050、I2C接口EEPROM芯片24LC512等。电路板采用4层结构设计,软件采用嵌入式实时操作系统μC/OS-II。实时操作系统将应用分解成多任务,简化了系统软件的设计,使控制系统的实时性得到了保证,提高了系统的稳定性与可靠性。

Armored vehicles will be used in huge quantity in wartime, so pretection of them from nuclear pollution and biological and chemical weapon receives special attention. This paper designed an armored vehicle three defense system controller based on ARM7, which included microprocessor LPC2294, interface chip MC33993 ＆ MC33996, D/A converter chip TLV5636, A/D converter chip AD7476, CAN transceiver MAX3050, and so on. The software was designed by using embedded real-time operating systemμC/OS-Ⅱ, which made the operation simplified, and improved the stability and reliability of the system.
