(1)结构上,采用平板式显示器与触摸屏,除适合卡板竖插的19机箱结构,还普遍推出前后插的机箱结构;适用于中小系统的一体化结构(整个系统都在一个机箱内)。
(2)应用上,和通用PC机一样,应用领域越来越广泛,除传统的过程控制、制造自动化外,还向楼宇自动化、公路收费等控制、管理方面扩展应用。
(3)嵌入式PC和嵌入式计算机,嵌入到设备内部,提供用户接口,管理数据输入、输出和指导设备工作的计算机。目前,中国在嵌入式设计中使用最多的还是80386和80486,这种CPU性能价格比高,有InTel、IBM、Cyixs、AMDT TI等著名CPU制造商支持。丰富的软件(包括操作系统、开发工具和应用软件)支持。嵌入式PC能在恶劣环境下(如高温、潮湿和震动等)长期可靠工作。嵌入式PC平均无故障时间(MBTF)为1000~150000h,而台式机仅为10000~15000h。硬件、软件和工业PC差不多。
