Design Of The Main Control System Of Multifunction Health Integrated Machine Based On ARM

A health integrated machine control system for telemedicine based on STM32 chip is designed and implemented.The system consists of a main control module,a display module,a network module,an electrocardiogram blood pressure module,a pulse oximetry module,and a urine analyzer module.Each information collection module can collect blood pressure,heart rate,pulse,blood oxygen,and urine of the human body.Liquid information,and can send this information to the STM32 chip through the serial port,STM32 will sort the information on the touch screen and send the data to the cloud via Ethernet.The cloud can be a higher-level medical institution in the central city.The medical institutions with advanced medical resources can analyze the health status of the users according to the data collected by the health machine system and give reasonable advice.The extensive application of the health one machine system can greatly ease the pressure of inadequate staffing at the primary medical institutions at the township level,while achieving the purpose of sharing the advantages of medical resources,improving the utilization of resources and facilitating the medical needs of remote users.This paper introduces the research background and significance of the topic according to the functional requirements of the system.By contrasting and selecting the STM32f429 chip as the master chip,the STM32f429 can be programmed up to 180 MHz.Rich interface resources,can expand peripherals with multiple functions,and communicate with multiple acquisition modules.Compared with the previous generation devices,the STM32f429 adds SDRAM driver units and LCD driver units,simplifies the system,and has the advantage of low power consumption under the premise of ensuring performance.The system uses a 7-inch LCD capacitive touch screen with a resolution of 800*480 for intuitive display of human-machine interaction and measurement data.The touch screen provides users with more human-friendly human-computer interaction and is convenient for users with different needs.The system has been ported to the FreeRTOS real-time operating system to meet the system's multi-task execution requirements while improving the efficiency of system resource allocation.In the FreeRTOS real-time operating system ported emWin graphical interface,emWin graphical interface controls to make the entire system interface more beautiful,while the interaction is more humane,in the case of basic medical needs can be met,so that the entire control system is more concise to Meet the needs of different groups.The system expanded the DP83848 network module and ported the lightweight protocol Lw IP to enable the health machine to perform network communication and synchronize the collected data to the cloud through Ethernet.Through the USART,Ethernet interface to achieve the communication between the various modules and the control system,the communication protocol written by software.
