PLC在病床呼叫系统中的应用 摘 要 信息时代的医院管理已经从传统的人管理模式，向智能化、电子化、网络化的高科技管理模式的方向迅猛发展。“PLC病床紧急呼叫系统”可以实现对医院病房的智能化管理，可实现呼叫、求救报警、信息储存、显示等等功能。患者在住院期间可能会在任意时间请求医生或护士进行诊断或护理。临床求助呼叫是传送临床信息的重要手段病床呼叫系统是患者向值班医生或护士发出紧急呼叫的工具要将患者的请求快速传送给值班医生或护士并在护士站的监控中心留下准确完整的记录提高医院和病室护理丰富病床呼叫系统的控制方式在满足病房与护士站实时通信同时能够方便地了解各病区的情况实现医院对全院的病房科学化管理。采用可编程控制器替代单片机作为核心控制件设计实现新型智能病床呼叫系统。实验结果表明用可编程控制器构成的病床呼叫智能系统结构更简单更易于推广。PLC，病床呼叫系统，病房管理，梯形图，I/O分配 DESIGN ON INTELLIGENT SICKBED CALLING SYSTEM BASED ON PLC ABSTRACT Information age of hospital management from traditional management mode, the person to intelligence, electronic technology, network management mode of rapid development direction. Emergency call PLC beds can make the hospital wards of intelligent management, can achieve the call, for information storage, alarm, display, etc. Patients hospitalized in May, at any time, ask your doctor or nurse diagnosis or nursing. Clinical help call is an important means of transmitting clinical information, call system is to hospital patients on an emergency call doctor or nurse, the tool will send request of patients with rapid doctor or nurse, and on the monitoring center in nurse station accurately record and left hospital and function is to improve nursing. For rich sickbed call system control mode, and nurses in ward, standing real-time communication can easily understand the situation, realized the hospital ward of the hospital wards scientific management. By using the programmable controller chip alternative controls, as the core design new intelligent hospital call system. The experimental results show that the PLC intelligent system composed of sickbed call more simple structure, more easily. The system USES the distributed control system, in each room, from a machine called signal acquisition, this ward alarm, display and control functions, Doctors and nurses in office setting machine.
