Preface

Today’s world has entered the information age, information has become an important strategic resource, information science has become one of the most active disciplines, information technology has changed people’s life and work style, information industry has become the leading industry of national economy. It is the basis of information transmission. Communication technology has become the fastest growing and fastest-growing industry in the information industry. At present, the rapid development of personal communication system and ultra-high speed communication network has promoted the further development of information science, and has become a powerful driving force for the international community and global economy in the 21st century. The modern communication technology of digital communication, satellite communication and sensor network has developed from wired communication to wireless communication, from communication between fixed equipment to mobile communication, from wireless communication to wireless Internet, to sensor network technology. The future communication will provide people with all-round and seamless mobile access, and ultimately realize any communication at any place and at any time, so that the communication technology can adapt to the needs of the development of society, showing a lasting momentum.
    And mechanical and electrical innovation is also progressing with the development of society. Innovation is the development of inheritance. Only when we have a deep understanding of the known objects, affirm and retain the reasonable contents, we can find the contents that can not meet the needs of the reality; if we have a certain understanding of the actual needs and have not seen the objects that can meet the needs, then innovation will have a starting point. The result corresponding to the starting point is not unique, but varies from person to person. There may be differences in principle and structure. This feature provides a wide space for innovative design. Mechanical and electrical innovation tries to combine demand problem, scientific theory, reference object and method application to show the application of mechanical and electrical innovation design.

前 言

当今世界已经进入了信息时代，信息成为一种重要的战略资源，信息科学成为最为活跃的学科领域之一，信息技术改变着人们的生活和工作方式，信息产业已经成为国民经济的主导产业，作为信息传输基础的通信技术则成为信息产业中发展最为迅速，进步最快的行业。目前，个人通信系统和超高速通信网络迅猛发展，推动了信息科学的进一步发展， 并成为 21 世纪国际社会和全球经济的强大动力。 数字通信、卫星通信以及传感器网络的现代通信技术从有线通信到无线通信，从固定设备间的通信到移动通信，从无线通信到无线因特网，到传感器网络技术不断发展。未来的通信将为人们提供全方位以及无缝的移动性接入， 最终实现任何人在任何地方、任何时间进行任何方式的通信， 使得通信技术适应社会的发展需要呈.现经久不衰的势头。
      而机电创新也不断随着社会发展而进步，创新是对继承的发展，只有对已知的对象有深刻的认识，在对合理的内容予以肯定、保留的同时发现不能满足现实需求的内容；对现实的需求有一定的了解且尚未见到能满足此需求的对象，创新才有了起点。起点对应的结果不是唯一的，而是因人而异，既可能有原理上的差异，也可能有构造上的差异，这种特性为创新设计提供了宽阔的空间。机电创新力图将需求问题、科学理论、参照对象与方法运用相结合、展示机电创新设计的应用。
