技术领域technical field
本发明涉及应力传感器技术领域，特别涉及一种基于可逆压敏变色胶的压线球检测方法，是一种对压敏变色材料及变色持续时间控制进行直观判断压线球的检测方法。The invention relates to the technical field of stress sensors, in particular to a method for detecting a crimping ball based on a reversible pressure-sensitive color-changing glue, which is a detection method for intuitively judging the crimping ball by controlling the pressure-sensitive color-changing material and the discoloration duration.
背景技术Background technique
一般体育运动，尤其是球类运动的专业化程度不断提高，对各类比赛中裁判判罚准确性的要求更为迫切。裁判判罚中要使人为错误影响结果的风险最小化。实际上，在每小时一百英里的水平速度下撞击边线的时间大约是一千分之一秒，这比人眼眨眼所需的时间快一百倍。运动员或观察员必须在眨眼之间确定球是否在界内，其实是不现实的。现阶段，在世界顶级球类比赛中，使用了“鹰眼系统”以辅助裁判的判罚，球的速度现在已经很及时地被测量并显示给观众，并且电子传感器被用来帮助裁判员/巡边员确定网球是否在规定的区域内。大大降低了裁判的误判。但是，“鹰眼系统”的处理过程需要一段较长的时间，导致比赛的中断。要保证比赛的流畅性、观赏性，如果处理时间过长，就会影响比赛节奏，也不利于观看。因此目前的比赛中限制了“鹰眼系统”的使用，不能每个争议球都用该系统。另外“鹰眼系统”也存在准确性的问题。鹰眼作为计算机辅助系统，并不能保证百分之百的正确率，一般误差控制在三毫米以内，需要注意的是，该系统是光学成像，对于不同颜色和大小的球的检测可能出现差错；最后，则是其成本较高，不易推广普及。In general sports, especially ball sports, the degree of specialization is constantly improving, and the requirements for the accuracy of referees' judgments and penalties in various competitions are more urgent. Referee decisions should minimize the risk of human error affecting the outcome. In fact, hitting the sideline at a horizontal speed of 100 miles per hour takes about a thousandth of a second, which is a hundred times faster than the time it takes a human eye to blink. It is unrealistic for an athlete or observer to determine if the ball is in bounds in the blink of an eye. At this stage, in the world's top ball games, the "Eagle Eye System" is used to assist the referee in making decisions, the speed of the ball is now measured and displayed to the audience in a timely manner, and electronic sensors are used to help referees/tourists The sidemen determine if the tennis ball is within the defined area. It greatly reduces the misjudgment of the referee. However, the processing of the "Hawkeye System" takes a long time, resulting in the interruption of the game. To ensure the smoothness and enjoyment of the game, if the processing time is too long, it will affect the rhythm of the game and is not conducive to watching. Therefore, the use of the "Hawkeye System" is limited in the current game, and this system cannot be used for every disputed ball. In addition, the "Eagle Eye System" also has accuracy problems. As a computer-aided system, Hawkeye cannot guarantee a 100% correct rate. Generally, the error is controlled within three millimeters. It should be noted that the system is optical imaging, and there may be errors in the detection of balls of different colors and sizes; finally, the It is expensive and difficult to popularize.
压边球的检测涉及感应技术，摈弃复杂的压电、液晶等压敏变色技术，利用简单的材料自身受外界刺激而变色的这种性质，可以实现以上的压敏变色要求。所采用压敏变色材料(mechanochromatic/piezochromism material)是光学性质(如吸收、反射、荧光和磷光等)在力作用下能够发生改变的一类功能材料。由于表面颜色变化肉眼可见，该材料可以用作压力传感装置。其变色原理在于材料在外力作用条件下，分子间弱作用力发生改变导致物质颜色变化。具体地，如将染料聚合物球嵌入具有良好弹性形变能力的硅胶中，受拉后，晶格距离增大，光的反射波长偏移至较短波长，可使表面变色。通过调整聚合物材料密度及缠绕方式，可控制冲击后变形回复时间，进而调整压敏变色持续时间。变形完全回复后，表面颜色恢复。截止目前，将该材料应用于球场边线检测未有报道。The detection of the edge holder involves the induction technology, abandoning the complex pressure-sensitive color-changing technology such as piezoelectric and liquid crystal, and using the simple material itself to be discolored by external stimuli, the above pressure-sensitive color changing requirements can be achieved. The mechanochromatic/piezochromism material used is a kind of functional material whose optical properties (such as absorption, reflection, fluorescence and phosphorescence) can be changed under the action of force. Since the surface color change is visible to the naked eye, the material can be used as a pressure sensing device. The principle of discoloration is that under the condition of external force, the weak force between molecules changes, which leads to the color change of the material. Specifically, if the dye polymer spheres are embedded in silica gel with good elastic deformation ability, after being stretched, the lattice distance increases, and the reflected wavelength of light is shifted to a shorter wavelength, which can change the color of the surface. By adjusting the density of the polymer material and the winding method, the deformation recovery time after impact can be controlled, and then the duration of pressure-sensitive discoloration can be adjusted. After the deformation is fully recovered, the surface color is restored. Up to now, there has been no report on the application of this material to the field sideline detection.
