摘要
为进一步完善现有的医院病房有线呼叫系统,改变病房与护士站的信息传递方式,创造更加整洁、便捷、高效的医疗环境,设计了以单片机为核心控制器的医院病房无线呼叫系统。设计主要包括资料收集及调研、软件设计、硬件搭建,联系现有环境的进行功能分析、测试等,确定了具体的功能需求,及需求功能之间优先级的表现形式。单片机作为主控制芯片,YL-100T为无线传输模块,结合矩阵键盘、独立按键、LCD液晶显示、无线通信、信号处理5个部分完成了本次设计。现场测试表明,在空旷区域,系统可以实现500 m无失真传输及处理;在楼宇内,系统可以实现1-5层无失真传输及处理,传输频率为433.078 2 MHz,波特率为4 800 Baud。系统具有可靠性高、成本低、可实现性好及可扩展等技术特点。
To replace the existing hospital ward cable system call , change the information transfer mode between rooms and nurses station, create a more clean, convenient and efficient medical environment, we designed a hospital ward wireless call system which microcontroller is the core controller. This design includes data collection ,research, software design, hardware structures, function analysis that contact the existing environment, testing, determine the function of the specific needs, and the demand of function between priority form.In this design , Microcontroller is the main control chip , YL-100T for wireless transmission module, in the process of communication, combined with the keyboard matrix, independent keys, LCD display, wireless communication and signal processing five parts to complete the design. Results： field test showed that in the wide area , the system can achieve 500m distortionless transmission and processing in the closed area （buildings）, the system can achieve 1-5 floats distortionless transmission, transmission frequency is 433.0782Mhz, baud rate for 4800Baud. Conclusion： the call system has high reliability, low cost, easy implementation and expansion, so it can be used in place of the existing medical ward calling system.
