RESUMO
Objective To design an intelligent fire alarm system for the hospital ward.Methods The system was developed based on controller area network,and had its functions realized with intelligent detector,supplementary modules and intelligent controller,which had the functions of fire alarm,control and monitoring and consisted of the modules for SCM control,temperature acquisition,infrared detection,smoke detection,audible and visual alarm as well as display.Results The system facilitated the hospital in fire monitoring,audible and visual alarm so as to reduce the fire risks.Conclusion The system gains high reliability and practicability,and thus is worthy promoting practically.
RESUMO
This paper describes the structure, operating principles, design method of both software and hardware of a centralized controlling system of infusion pumps based on CAN bus. The system can monitor the status information and control the infusion parameters of many infusion pumps simultaneously. It provides a more complicated cliaical infusion treatment means, greatly eases the work burden on doctors and nurses, and promotes the effects of treatment and nursing.
RESUMO
This paper introduces the design of automatic biochemistry analyzer based on CAN field bus. The hardware and software of a single network node and several problems are narrated. Some related flow charts and source codes are also given. The involvement of CAN bus in the design of automatic biochemistry analyzer enhances the efficiency and the degree of automatization.
RESUMO
Objective Nowadays,with the development of medical vehicle,there are many parameters for inspection in its interior.It has disadvantages,such as complex routing and low system reliability,to use DCS.CAN bus technology can decrease routing and enhance system reliability.Methods OPC technology was used.A temperature supervisor control program and a database application were designed by VB,and the temperature was control by the fuzzy control methods.Results The temperature supervisor control system was established with CAN bus to explore the application of CAN bus in the medical vehicle.Conclusion It can enhance the system's reliability to use CAN bus technology in the medical vehicle.
