摘要
研制了一种新的医院监护系统 ,即利用单片机串行通讯功能 ,通过主站对各从站的轮流查询 ,实现医院实时监护 .针对单片机易受外界干扰而使程序“跑飞”的现象 ,主站利用 MAX70 6提高系统抗干扰能力 ,而从站则利用软件即可判断出程序是否死机 .运行结果表明 ,系统稳定可靠 .
A new kind of hospital monitor system is put forward. The real time monitor of hospital is realized through the main station inquiring about substations in turn by using serial communication function of the single chip microcomputer. In view of the phenomenon of the single chip microcomputer suffering the external jamming easily, the main station uses MAX706 to improve the antijamming ability of the system, and the substations uses the software to judge the program whether to enter the circle to ruin . The result shows that the system is stable and reliable.
