Abstract
A high-precision gold-labeled strip reader comprises a power supply (1), an ARM (advanced RISC machines) controller (2), a liquid crystal touch color screen (3), a tested gold-labeled strip module (4), an achromatic color short-focus imaging lens (5), a linear-array or area array CCD (charge coupled device) acquisition system (6) and an LED light source module (7). The reader adopts the circular LED light source module, light source pairs with different wavelengths can be arranged as required to realize uniform lighting, and the reader has the advantages of small size and long service life; meanwhile, multi-sample measurement without a motion element is realized, the difference between gold-labeled strips is eliminated, and the measurement precision is improved. The measurement efficiency and the measurement precision are improved simultaneously, and the whole instrument is simple in structure and convenient to operate.
Description
Technical field
The invention belongs to scientific analysis Instrument technology field, specifically just relate to a kind of high precision gold test strip reader, the volume reducing gold test strip reader can be conducive to, improve the measuring accuracy of gold test strip reader.
Background technology
Along with the quickening of modernization, environmental pollution is on the rise, and food-safety problem, medical and health conditions are more and more subject to concern and the attention of people.The focal issue that the standardized management of food security and health care makes safety and quality testing become scientific research institution and each large enterprises jointly to pay close attention to, how can detect various pollutant in environment at the scene accurately and rapidly, ensure food safety and diagnose sufferer, for minimizing and eliminate various harm hidden danger, in time seek medical advice and effectively prevent accident play a part very important.Nm of gold mark detection paper method easy to carry, detect fast, simple operation and other advantages, make the method be subject to paying close attention to more and more widely, current detection paper method has been widely used in the every field such as food security, water quality quality, health care detection.But Most current analyses detection paper can only lean on visual judgement, when detecting, owing to being that human eye directly observes measurement result, the resolution characteristic of different people to color is not quite similar, and causes testing result to vary with each individual.When sample concentration reaches the detectability of test paper, the factors such as test paper is in the critical conditions of color development area, the difference of extraneous light intensity and test paper sensitivity, human eye can be caused to determine, and testing result belongs to negative or positive.Detection paper method can not read concrete measured value, can only qualitative detection, cannot meet precise requirements.And the gold mark reader that market is commonly used is owing to reading single deck tape-recorder, measuring accuracy is lower, measures efficiency lower.
Summary of the invention
The object of the invention is for above-mentioned existing gold test strip reader measuring accuracy low, single deck tape-recorder can only be read, measure the technological deficiency of inefficiency, a kind of high precision gold test strip reader is provided, this reader adopts annular multiple light courcess can carry out measurement to many cards and reads, and improves reading efficiency and reading accuracy.
