摘要
介绍一种医用自动肺活量测试仪的设计方案,描述自动肺活量测试仪各部分电路的设计,给出系统AD转换的子程序。该系统以MSP430F449为控制芯片,采用MPXV7002压力传感器,简化电路设计;同时该设计方案体积小,耗电少,操作方便。
In this paper, a design program for medical automatic vital capacity instrument is introduced. Every parts of circuit design about the vital capacity tester are described. The A/D program design is described. The system consists of the microchip MSP430449 and the press sensor MPXV7002. It has the characteristics of small size, low power and convenient operation.
