【摘要】：针对社会上儿童、老人走丢这一严重的现象,许多相应的防走丢产品被生产出来,如手环、手表。这些产品在一定程度上帮助人们实时了解老人、小孩的安全情况。使得人们可以及时处理老人小孩的危险情形。在移动互联网技术的推动下,GPS的应用服务系统和手机等移动终端的普遍使用,更为防走丢系统的设计与开发提供了新的方向。本文首先分析设计防走丢产品的重要性,然后对防走丢系统进行深入的研究。本文主要从系统的功能和性能方面分析系统的局限性并提出相应的优化措施。目前防走丢系统的局限性主要体现在定位的距离有限、定位的精度需要进一步的提高。这对这两方面的问题,本文从三个方面来优化防走丢系统。优化方法如下:1)改善系统的功能,对系统已经有的指引功能进行优化。防走丢系统在监护人查找被监护人的行径时,系统会提供一条路径给监护人来指引监护人找到被监护人。对系统的这个功能改进之后系统不仅会提供路径给监护人还会将同一路径提供给被监护人,并且可以语音指示被监护人应该怎样沿着路径前进。这样双方可以在路途中的某个地方相遇。2)优化最优路径规划算法。对系统内关于最优路径的算法改进,使系统能够提供更精确的路径来帮助监护人寻找被监护人。3)改善系统内地图的定位精度。通过提高地图采集地理位置信息的精度来提高地图的定位精度。定位精度提高系统提供给监护人的路径就会越精确。对系统的优化提出的方法最终的目的只有一个,那就是提高监护人寻找失踪人员的效率,让失踪人员能尽早的脱离困境或危险。
[Abstract]:In response to the serious phenomenon of social children, the elderly lose their lives, many of the corresponding products, such as bracelets and watches, have been produced to help people get to know the elderly in real time. The safety of children enables people to deal with the dangerous situations of old people and children in time. With the help of mobile Internet technology, GPS application service system and mobile terminals such as mobile phones are widely used. It also provides a new direction for the design and development of the anti-loss system. This paper first analyzes the importance of the design of the anti-loss products. Then the paper makes a deep research on the anti-loss system. In this paper, the limitations of the system are analyzed from the aspects of system function and performance and the corresponding optimization measures are put forward. At present, the limitation of the anti-loss system is mainly reflected in the limited distance of positioning. The accuracy of positioning needs to be further improved. For these two problems, this paper optimizes the anti-loss system from three aspects. The optimization method is as follows: 1) to improve the function of the system. Optimize the guidance function already available in the system. When a guardian looks up the behavior of a guardian, The system will provide a path to the guardian to guide the guardian to the guardian. The system will not only provide the path to the guardian but also the same path to the guardian after this function of the system has been improved. And can voice indicate how the guardian should go along the path, so that both sides can meet somewhere on the way. 2) optimize the optimal path planning algorithm. Improve the algorithm about the optimal path in the system. So that the system can provide a more accurate path to help the guardian find the guardian. 3) improve the positioning accuracy of the map within the system. By improving the accuracy of the map collection of geographical location information, improve the location accuracy of the map. The more accurate the path the system provides to the guardian, the more accurate the proposed approach to system optimization is, That is to improve the efficiency of guardians looking for missing persons, so that missing persons can get out of trouble or danger as soon as possible.
