中文摘要:
      尿检仪是非常重要的医学诊断设备,然而传统的尿检仪从原理设计上具有很大的局限性。针对常规尿检仪具有体积大、成本高等缺点,研究了基于电容式传感器的尿检原理,设计了一种便携式无线尿检仪。系统以电容式生物传感器TouchSensor为检测元件并通过ACAM公司的Pcap01检测其各单元电容变化,采用意法半导体公司的32位低功耗微控制器STM32L152,通过Dialog公司的低功耗蓝牙芯片DA14580进行无线通信。为了获得精准的电容值,提出了一种基于拉依达准则的数据处理算法。实验结果表明该尿检仪具有精度高、灵活性强等特点。
英文摘要:
      Urine test instrument is an important medical diagnostic equipment, however the traditional instrument urine has been designed with great limitations. In order to aviod the disadvantage of large volume and high cost, this paper designed a portable wireless urine test instrument based on the principle of the capacitive sensor. This system take capacitive sensor TouchSenser as the detecting element and using Pcap01 ACAM to detect the capacitance change of every unit. The controller of this system was STM32L152, an 32 bit microcontroller of STMicroelectronics, with low power consumption. Low power Bluetooth chip Da14580 of Dialog Semiconductor was used to wireless communicate. In order to obtain accurate capacitance value, proposes a data processing algorithm based on Pauta criterion. The experimental results show that the urine test instrument has the characteristics like high precision, flexibility and so on.
