【摘要】 针对医院手术室多参数的监控,介绍一种利用串口扩展芯片GM8125开发该监护设备数据通信系统的方法。采用AT89S8252作为该系统主控MCU,利用GM8125进行多串口扩展,使得IT电源监控数据、空调控制参数、医用气体压力参数、上位机控制参数等多种数据方便地实现集成。经实际测试,该种控制方法简单,最大限度地减少控制线,不需要占用太多主机的系统资源。在完成可靠的数据通信的同时,也充分满足系统的实时性要求。更多还原

【Abstract】 In order to monitor the multi-parameter in hospital operating room,the application of GM8125 in data communication system for the information board is introduced.AT89S8252 is adopted for the main MCU.Due to realizing COM extension by using GM8125,the multi-data is expediently integrated including the data of monitor for IT power supply,the controlling parameter for air condition,the pressure parameter of gas used in hospital,the controlling parameter for upper computer.The practical results show that the method has the characteristics of the ability of controlling easy.The ability of reducing the data line and the ability of de- pressing system resources of the main set.When reliable data communication is accomplished,the suited time requirement of the sys- tem will be fully satisfied.更多还原
