摘　　要：针对传统病房呼叫系统存在的布线复杂、易出故障、维修不便等问题,本文采用AT89S51单片机作为主控芯片,PT2262/2272作为无线收发模块的核心芯片,并配以相应的锁存电路、单片机报警显示电路和复位电路,设计了无线病房呼叫系统。实测结果表明,该系统可靠稳定的传输距离达100m以上,具有一定的抗干扰性,能够满足用户实际使用要求。系统性能稳定,操作简单,可以有效地代替传统的有线呼叫系统。In order to solve some existing problems in the traditional ward calling system, such as wiring complexity, ease for failure and maintenance inconvenience, in the article, a new ward wireless calling system is designed with AT89S51 SCM as the master chip, PT2262/2272 as the core chip of wireless transceiver module, and with appropriate latch circuit, alarm display circuit and reset circuit were used to design the ward wireless calling system. The actual test showed that the stable and reliable transmission distance was more than 100 meters, with a certain degree of anti-interference, and it is able to meet the actual requirements. The system has stable performance and simple operation, so it can replace the traditional wired calling system effectively.
