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, we give full consideration to the system miniaturization, real time and low power consumption. This system with TMS320C5515 fixed-point processor as the core, concludes analog signal receiving amplifier circuit, analog-digital conversion circuit, the digital signal storing, processing circuit, LCD display circuit and power management circuit. We achieve the detection of ECG, respiration, SPO2, noninvasive blood pressure and pulse. In the design comprehensive consideration is given to the overall performance and structure (including power management).We ensure the real-time performance, miniature and low power consumption of the system ultimately. The hardware system card is showed below in
