摘　　要：尿湿监测对残疾人、瘫痪者等患有行动不便症的病人以及医院护理工作具有重要的意义。介绍了一种基于单片机并行接口方式的病床尿湿监测系统,该系统以STC89C58RD+单片机为核心,从信号采集、存储到时钟记录、液晶显示、打印输出全部采用并行接口器件;采用循环扫描,优先报警,不处理报警的设计思路,配以蜂鸣器、指示灯等声、光器件,能够实时有效监测多达96个病床的尿湿情况,并通知护理人员进行处理。该系统对报警信号响应快速、灵敏,满足实际应用要求。Urine leakage monitoring is of great significance for hospital care and the patients suffering from reduced mobility, such as the disable, theparalyzed. A sick bed urine leakage monitoring system based on MCU peripheral interface mode is presented. The system adopts STC89C58RD+ as amicroprocessor, and can detect more than 96 urine leakages rapidly and effectively by peripheral interfaces for signal sampling, storage, time record,liquid crystal display and printing output. Taking circulative scan, different priority alarm and no-treatment alarm as a design thought, the system canrespond each leakage and inform nurses of treating alarms immediately by sound and photoelectric indicators. The system shows its great advantages inmonitoring alarm signals and satisfies the need of practical applications.
