微型多参数人体体征监护仪

The Design of Human Miniature and Multi Parameter Monitor

为满足重离子治癌系统中对人体体征参数的要求设计了多参数监护仪。在设计中充分考虑了系统的微型化、实时性和低功耗[1]。该系统以TI公司高性能低功耗定点处理器TMS320C5515为核心搭建了模拟信号调理电路、模数转换电路、数字信号存储处理电路、LCD显示电路,解决了心电、呼吸、血氧、无创血压、脉搏等人体征信号的检测[2]。设计中围绕DSP全面考虑了电路的整体性能和结构(包括电源管理),最终保证系统的实时性、超微型和低功耗。

In order to meet the need of heavy particle therapy system on human physical signs parameters the multi parameter monitor was designed. During the design process, full account of the system miniaturization, real time and low power consumption. This system with TI company of high performance and low power con- sumption TMS320C5515 fixed -point processor as the core structures of the analog signal conditioning circuit, analog- digital conversion circuit, and the digital signal storing and processing circuit, LCD display circuit, solve the detection of ECG, respiration, SPO2, noninvasive blood pressure, pulse. In the design around DSP comprehensive consideration is given to the overall performance and structure （ including power management ）, ultimately ensure the real - time performance, miniature and low power consumption of the system.
