Abstract: This paper designs and implements a new multi-parameter monitor based on the OMAP3 platform of Texas Instruments, which is used to detect six basic life parameters of human ECG, heart rate, blood oxygen, blood pressure, respiratory rate and body temperature. The system adopts ARM+DSP dual-core chip OMAP3530 as the core processor, and Google Android 2.1 as the operating system, which expands the parameters acquisition front end, touch screen, SD card storage circuit and network access circuit module, and realizes 6 basic life parameters for human body. Measurement, display, storage and network transfer functions. In modern medicine, the use of multi-parameter monitors for real-time monitoring of critically ill patients can timely understand the comprehensive factors such as cardiopulmonary function, blood pressure and oxygenation capacity, and plays a very important role in the treatment of patients. Multi-parameter monitors have found wide application in ward care and first aid systems. The multi-parameter monitor based on the traditional PC platform has high cost, large volume, complicated operation and limited use range. The portable multi-parameter monitor with the single chip as the core has low computing power, single function and simple interface, and can only perform simple signal display and storage. This article takes Texas Instruments' (TI) ARM+DSP dual-core processor OMAP3530 as the core, and expands the parameters acquisition front-end, touch screen, SD card storage circuit and network access circuit and other modules, designed and implemented a real-time detection, display and storage. New multi-parameter monitors with functions such as network transmission. Based on the excellent performance of dual-core chips, the system can use high-efficiency and complex algorithms to quickly and accurately detect, denoise and optimize various life parameters. Google Android's rich application support provides a good monitoring interface for the monitor. Network features and application extensibility. The doctor can use the monitor to grasp the patient's information in real time or remotely, and the user can also measure it at home. This will be an important development direction for the new generation of “ digital medical community/hospitalâ€. system structure Processing core The OMAP3530 processor is fabricated on a 65nm low-power process and integrates a 600MHz Cortex-A8 flex core and a 430MHz TMS320C64x+ DSP core. ARM+DSP's dual-core architecture optimizes operating system efficiency and code execution. The ARM side is responsible for system control and the DSP side is responsible for heavy real-time signal processing tasks, thus successfully solving the optimal combination of performance and power consumption. The OMAP3530 with dual core construction is ideal for the design of new multi-parameter monitors. Low power consumption can better realize the portability of the monitor, meet the special needs of field rescue; ARM support for multiple operating systems can ensure the stability of the system and a good monitoring interface; DSP's powerful computing power can ensure each Fast, accurate and complex analysis of life parameters. Hardware architecture The system block diagram is shown in Figure 1. The monitor is designed using a classic C/S (Client/Server, client/server) architecture, which can be used offline or transmitted to a remote PC service via Ethernet or Wi-Fi network. end. The vital signs of the human body are obtained by sensors such as lead electrodes, blood oxygen probes, and sleeves. After denoising, amplifying, and A/D conversion at the front end of the parameter acquisition, they are sent to the OMAP3530 through the serial port for detection, display, and storage. And network transfer and other processing.
