摘要

基于比色原理结合多通道并行检测设计的高效检测技术,开发一种完全自动化的仪器。仪器可通过对样品浊度的测定了解微生物生长情况,整合控温震荡培养功能于一体,为实现多种微生物(包括细菌、真菌、酵母、噬菌体、变形虫、细胞和藻类等)的在线监测培养,加速微生物快速反应,缩短培养时间,可测试96孔板中微生物生长情况,随时在线监测。其核心是通过一套检测系统同时实现 8 个样本通道的独立检测,再通过模数转化芯片(ADC)将模拟信号转化为数字信号给到单片机,同时,单片机控制电机、加热片、风扇等负载,具备溶液摇匀功能和控温技术,在保证检测精度的前提下大幅提升检测效率。

Abstract

An efficient detection technology based on the colorimetric principle and combined with multi-channel parallel detection. Its core lies in using a detection system to independently detect 8 sample channels simultaneously. Then, through the analog-to-digital conversion chip (ADC), the analog signals are converted into digital signals and sent to the microcontroller. At the same time, the microcontroller controls loads such as motors, heating elements, and fans, featuring solution mixing function and temperature control technology. It ensures detection accuracy while significantly improving detection efficiency. It is widely applied in scenarios requiring batch sample analysis (such as clinical diagnosis, environmental monitoring, food safety, etc.).
