Description
技术领域technical field
本发明涉及食品安全检测技术领域，特别是涉及基于图像识别原理的食品安全检测装置和方法。The invention relates to the technical field of food safety detection, in particular to a food safety detection device and method based on the principle of image recognition.
背景技术Background technique
随着电子及计算机技术的不断发展和金标试纸的提升，利于现场检测的金标分析仪的研制逐渐变成一种趋势，如何实现快速精确的定量检测成为国内外的热点。随着试纸制备技术的不断发展，一条试剂条不再只能检测一种有害因子，而是能够同时检测两种以上的有害因子。能够同时检测两种有害因子以上的试剂条叫做高通量试剂条，试剂条上包含一条C带和多条T带。但是，在相同的条件下，现在的金标读卡仪并不能够对高通量试剂条进行检测。随着图像技术的不断发展和试剂条制备技术的进步，利用图像处理的方法能够检测高通量试剂条的条件已经成熟。With the continuous development of electronic and computer technology and the improvement of gold standard test paper, the development of gold standard analyzers that are beneficial to on-site detection has gradually become a trend. How to achieve fast and accurate quantitative detection has become a hot spot at home and abroad. With the continuous development of test paper preparation technology, a reagent strip can no longer only detect one harmful factor, but can detect more than two harmful factors at the same time. Reagent strips that can detect more than two harmful factors at the same time are called high-throughput reagent strips, and the reagent strips contain a C band and multiple T bands. However, under the same conditions, the current gold label reader cannot detect high-throughput reagent strips. With the continuous development of image technology and the advancement of reagent strip preparation technology, the conditions for using image processing methods to detect high-throughput reagent strips have matured.
目前生物芯片技术大多采用荧光信号，由于荧光需要激发光，杂散光的存在限制了荧光法的灵敏度。由于需要光源机构的存在，往往这类仪器机构复杂，比较沉重。At present, most biochip technologies use fluorescence signals. Since fluorescence requires excitation light, the existence of stray light limits the sensitivity of fluorescence methods. Due to the need for the existence of the light source mechanism, the mechanism of this type of instrument is often complicated and heavy.
化学分析具有荧光的特异性，背景光很低、不需要激发光源、反应物所在处即可进行检测，使荧光方法中遇到的光散射的干扰得到减小，是一种十分优秀的定量分析方法。同时，CCD成像扫描检测方法减去了激发光装置，能够减少机构的复杂性和减少体积。Chemical analysis has the specificity of fluorescence, the background light is very low, and it can be detected without excitation light source and reactant location, which reduces the interference of light scattering encountered in fluorescence methods, and is an excellent quantitative analysis method. At the same time, the CCD imaging scanning detection method subtracts the excitation light device, which can reduce the complexity and volume of the mechanism.
因此希望有一种基于图像识别原理的食品安全检测装置和方法可以克服或至少减轻现有技术中的问题。Therefore, it is desired to have a food safety detection device and method based on the principle of image recognition that can overcome or at least alleviate the problems in the prior art.

The stepping motor 26 rotates the connecting rod 18, so that the connecting rod drives the CCD image sensor 24 to rotate back and forth on the reagent strip light-shielding pipeline 23 and the biochip light-shielding pipeline 13, and precisely stops on the first through hole and the second through hole respectively, and the CCD The image sensor 24 detects the images of the reagent strips and biochips respectively, collects the images, transmits the data to the ARM office through USB, wireless transmission, RS232 or Ethernet port for corresponding data processing, and finally analyzes and stores them, and uploads them to the database.
试剂条载物台和生物芯片载物台在不同的遮光管道下，两个遮光管道上分别都有圆形通孔，而CCD图像传感器通过通孔采集图像。试剂条遮光管道23和生物芯片遮光管道13的内部结构不同，试剂条的遮光管道23只有一个环形LED白色灯源安装在管道，而生物芯片遮光管道13内设置有专业凸透镜33在管道内部装有物镜31和滤镜30。The reagent strip stage and the biochip stage are under different light-shielding pipes, and the two light-shielding pipes have circular through holes respectively, and the CCD image sensor collects images through the through holes. The internal structure of the reagent strip light-shielding pipeline 23 and the biochip light-shielding pipeline 13 is different. The light-shielding pipeline 23 of the reagent strip has only one ring-shaped LED white light source installed in the pipeline, while the biochip light-shielding pipeline 13 is provided with a professional convex lens 33 inside the pipeline. Objective lens 31 and filter 30.
试剂条载物台和生物芯片载物台因为试剂条和生物芯片结构不同，因此两者的结构也不相同。试剂条都是有塑料壳身，壳身都是固定形态，不易变形，因此对于试剂条，只需要把试剂条插入到检测口里就行，而且只需要把检测区域插入其中，就能保证试剂条的位置，利于CCD图像传感器采集图像，同时方便拿取；而生物芯片不同，生物芯片没有壳身，因此需要把整个壳身送入检测口，因此需要设计专门的传动平台，把生物芯片载物台带入遮光管道下。The reagent strip stage and the biochip stage have different structures because of the different structures of the reagent strip and the biochip. The reagent strips have a plastic shell, which is fixed in shape and not easy to deform. Therefore, for the reagent strip, it is only necessary to insert the reagent strip into the detection port, and only need to insert the detection area into it to ensure that the reagent strip The position is good for the CCD image sensor to collect images, and it is easy to take at the same time; and the biochip is different, the biochip has no shell body, so it needs to send the whole shell body into the detection port, so it is necessary to design a special transmission platform to load the biochip The table is brought under the shading pipe.
