摘　　要：提出并设计开发一套心肌细胞搏动压检测单元。基于压电薄膜传感器,设计心肌细胞搏动信号前端采集单元,并加入合理的数字滤波算法对采集到的信号进行滤波。经过CAN总线传输,将处理后的数据送到后端触摸屏显示;后端控制单元接受触摸屏输入信号,通过CAN总线将控制信号送到前端,从而实现培养液供给的智能控制。完成系统整体方案设计,前后端单元的硬件电路设计以及相应控制算法的软件开发,经初步试验,实现心肌细胞搏动参数实时检测和显示。该设计为心肌细胞搏动参数实时观察以及无菌、无污染的智能化小规模培养提供一种有效途径。Propose and develop a simple pulse pressure detection unit of cardiomyocytes. Design the front acquisi-tion unit of cardiomyocytes thump signal based on the piezoelectric film sensor,which adds a suitable digital filteralgorithm for filtering the collected signals. Through the CAN bus,the data after treatment will be sent to back-endtouch screen to display;The back-end control unit can accept input signal of touch screen and send the correspond-ing control signal to front-end via the CAN bus,which is used to achieve intelligent control of supply for culture me-dium. Finish the overall system design,hardware circuit design of front and back-end unit,software development ofrelevant control algorithm. Then the design accomplished real-time pulse parameter detection and display of cardio-myocytes through preliminary test. This design provides an effective method of real-time observation of cardiomyo-cytes pulse parameter and sterile,non-pollution,small-scale intelligent cultivation.
