碩士 === 國立虎尾科技大學 === 光電工程系光電與材料科技碩士班 === 107 === In this paper, acetylcholinesterase detection method was used, Raspberry Pi 3B+, Logitech C310, QT Creator and 3D design and printing technology were used. In this study, Acetylcholinesterase was used for color recognition and image capture of the RGB primary color changes of chemical reactions during pesticide detection, and RGB data and integral area were accessed to calculate the PPM corresponding to the integral area by the formula of Fitting function of Origin Pro8. The formula was put into the program. When we put the matrix into the glass bottle, the start button on the interface will trigger the solenoid valve to open. The detection liquid containing the pesticide will flow into the glass bottle through the solenoid valve. The camera picks up the image and identifies it. After 20 seconds of testing, the program will be inserted. The formula of PPM calculates and shows the PPM corresponding to the integral area after calculating. We can also use mobile phones to obtain the data after raspberry pie detection (R, G, B, PPM, Time), and when we press the start button of the human interface, the data will be accessed in an array way and the file name will be time, so that the file will be saved. It will not overlap the data and will be convenient for us to study in the future. This paper also uses TCP client and server mode to transmit data offline without network. Raspberry pie becomes a server mobile phone as a client. Raspberry Pi 3B+ should be set as AP mode as Wifi Sharer before data transmission. Both mobile phone and raspberry pie need to add QTCPsocket and QTcpServer. The listen function in the raspberry pie begins to accept the connection of the mobile phone (Client) and starts to send the data into the slot. The slot transmits the data for the mobile phone to read. QString date 2 = QString:: Number is used to transfer the integer or floating-point number into a string for transmission. This function is convenient to add in this study. And clearly from the mobile phone to see the detection data.
