【摘要】 系统的硬件主要由CPU卡(ST-8811H)、键盘显示卡(ST-8301)、16路12位A/D卡(ST-7404)组成。由于利用系统时钟中断源并采用STD-PC BIOS功能调用实现定时采样,从而省去定时器/计数器卡,使系统硬件开销最小。更多还原

【Abstract】 The hardwares of system mainly consist of CPU Card (ST-8811H), Keyboard Display Card (ST-8301) and 16-route 12-bit A/D Card (ST-7404). As system clock interrupt source is used and STD-PC BIOS function transfer is used to proceed timing sampling, timer/counter card is omitted and system hardware is most economical.更多还原
