Microcontroller applications are more and more widely, from the beginning of job control, and now aerospace, fire safety, work data collection, petroleum exploration, rail transportation, and building automation, and even now many home appliances are single-chip microcomputers. With the rapid development of computer technology, microcontroller has been gradually developed and become a key technical discipline. With social progress and development of the continuous improvement of medical standards, modern hospital care needs to be informed and to deal with simple and timely patients sudden illness. Design based on single-chip microcomputer of hospital beds in the same time call control system can monitor many beds, to avoid some disadvantages :the inconvenience of artificial call and poor result, these are essential to modern hospital equipment. With the call control system of hospital beds, hospital care has become more convenient and comprehensive, no longer in short supply or failure to timely detection of sudden illness and trouble. A method to devise a multi-bed system is based on the Microcontroller AT8
