摘要
针对细菌总数快速检测的需求,利用ATP荧光检测技术,设计了一款细菌总数ATP荧光快速检测仪。通过设计一个恒温的检测暗室,有效降低了环境温度与环境光的干扰。采用光电倍增管作为光电转换器件,采用CPLD器件实现了光子计数脉冲信号的采集,从而实现了微弱荧光的检测。采用蓝牙无线通讯技术实现了数据传输。ATP标准溶液检测实验结果表明,仪器的检测值与ATP浓度呈良好线性关系,相关系数达到0.9964。
Aiming at the requirement of rapid detection of total bacteria, an ATP Fluorescence Rapid Detector for total bacteria was designed by using ATP fluorescence detection technique. Through the design of a constant temperature detection chamber, effectively reducing the ambient temperature and ambient light interference. Using photomultiplier tube（PMT） as photoelectric conversion device, CPLD device is used to realize the photon counting pulse signal acquisition, thus realizing the detection of weak fluorescence. Using Bluetooth wireless communication technology to achieve the data transmission. The results of ATP standard solution test show that the detection value of the instrument and the ATP concentration showed a good linear relationship, the correlation coefficient of 0.9964.
