技术背景technical background
近年来，随着人们闲暇时间和收入的增多，参观博物馆、科技馆等场所不仅成为时尚，而且成为人们学习、猎奇、寻根、休闲等方面精神生活的需要。而参观者的收效如何，很大程度上依赖于参观时讲解人员的讲解质量的高低。随着时代的发展和社会的进步，博物馆、纪念馆、科技馆等各种展馆的讲解事业进入了一个新的发展阶段，观众的精神文化需求在不断提高，渐渐不再需要简单的说教式讲解。纵观国内大多数博物馆、纪念馆、科技馆的讲解员，由于年龄、学识的差异或者客观环境和工作背景的特殊性，往往还在进行着简单重复性、机械性的劳动，只注重外表、外形，而内在知识沉淀积累不够，不能满足参观者对讲解内容精度和深度了解的需求。展览馆内，如何让参观者能在安静情况下参观并听到讲解员柔和而甜美的讲解，而不是以为自己走进了菜市场。诸如此类，在博物馆、科技馆以及行业的展会等等需要一个人对很多人讲解而环境不是很安静的情况下，如何达到清晰的讲解和听取效果？因此，特别需要提出一种方便地随机讲解展品的自动解说设备，省去了解说员的长期培训和解说员的辛劳解说工作，并且能够更方便地使参观者得到高水平的解说，提高展览和宣传教育的效果。In recent years, with the increase of people's leisure time and income, visiting museums, science and technology museums and other places has become not only a fashion, but also a need for people's spiritual life in terms of learning, novelty hunting, root seeking, and leisure. The effectiveness of the visitors depends largely on the quality of the explanations given by the explainers during the visit. With the development of the times and the progress of society, the explanations of various exhibition halls such as museums, memorial halls, and science and technology museums have entered a new stage of development. The spiritual and cultural needs of the audience are constantly improving, and simple didactic explanations are gradually no longer needed. . Looking at most domestic museums, memorial halls, and science and technology museums, due to differences in age, knowledge, or the particularity of the objective environment and work background, they are often still performing simple, repetitive, and mechanical labor, focusing only on appearance and appearance. , and the accumulation of internal knowledge is not enough to meet the needs of visitors for the accuracy and in-depth understanding of the explanation content. In the exhibition hall, how to allow visitors to visit in a quiet environment and hear the soft and sweet explanation of the guide, instead of thinking that they have entered the vegetable market. And so on, in museums, science and technology museums, and industry exhibitions, etc., where one person needs to explain to many people and the environment is not very quiet, how to achieve clear explanation and listening effect? Therefore, it is particularly necessary to propose an automatic explanation device that can easily explain the exhibits at random, save the long-term training of the explainer and the hard work of the explainer, and enable visitors to get high-level explanations more conveniently, improving the exhibition and exhibition. The effect of publicity and education.
