摘要
在液漏检测领域, 许多应用场合对成本敏感, 而且又对空间分辨率有相对高的要求。但目前市场上很难选配到具备厘米级空间定位能力, 而且价格低廉的液漏传感器, 造成在这一特定需求空间内的应用真空。与当前流行的单一光源定位思路不同, 文章介绍了一种多源定位的方法, 可以实现低成本, 短距离(10m)内较高的空间分辨率(5cm)。详细介绍了传感器检测与定位原理、加工方法, 以及相关工艺参数的影响。
Abstract
In the field of liquid leakage detection, many applications are sensitive to cost and require relatively high spatial resolution. But at present, it is difficult to choose the liquid leakage sensor with the ability of centimeter-level spatial positioning and low price in the market, resulting in the application of vacuum in this specific requirement. Different from the current popular single light source positioning idea, a multi-source locating method is introduced, which can achieve a high spatial resolution (5cm) within a short distance (10m) by low cost.The principle of sensor detection and location, the processing method and the influence of related process parameters are introduced in details.
