"基于单片机的病床呼叫控制系统设计及应用研究"

医疗监护. Traditional manual calling methods can no longer meet the needs of real-time monitoring of patients. In this context, the sickbed calling device is becoming increasingly popular. This paper focuses on the issues of hospital care and designs a sickbed calling control system to improve the quality and efficiency of nursing in hospitals and wards, and promote good doctor-patient relationships. This design is based on the STC89C52 single-chip microcomputer control system. It collects calling data through a keypad circuit, processes the data through the single-chip microcomputer control system, and then sends the processed data to the LCD1602 for display of the called bed number. It also includes functions such as sound alarms, light alarms, and multi-bed alarms processing. The sickbed calling control system device designed in this paper is simple, reliable, low-cost, has good real-time performance, and is easy to maintain and install. It is of great significance for improving doctor-patient relationships and enhancing the quality of nursing in hospitals. Key words: STC89C52; sickbed; calling control; counter; LCD.
