摘  要：随着现代社会的发展，无线Wi-Fi技术、无线物联网的高速发展，以各种各样智能设备的广泛运用，人们的生活也更趋于方便，简捷智能，大多数智能设备都和无线网络技术息息相关。ESP8266是一个完整且自成体系的Wi-Fi网络芯片,作为一种最新的技术正快速得发展，虽然目前并没有能运用到大型工程的目标，但在我们日常生活中却到处透露着这种新型芯片的神奇。稍微有点涉猎的人都可以用ESP8266芯片为核心设计一个小型局域网，让智能设备在范围内实现互相通信，人们现代所追求的智能家居也是可以这样实现的。ESP8266芯片的高度集成、低功耗、廉价等特性方便了研究，特别是最近几年已然成为最受欢迎的一款芯片了，国内对该芯片的Wi-Fi无线网络技术研究不是很全面，但理论已经完善，我们需要开发更多的实际运用，这项技术在物联网、智能家居，甚至一些公共场所的应用领域具有大的实用性。

本篇文章文以ESP8266芯片为核心的无线模块为基础，对它的AT和SDK指令进行开发，然后用一个或多个模块进行合理设计。由于ESP8266模块具有AP+STA共存的模式，可以利用这一特性建立小型的无线局域网，让外围的移动终端等智能设备通过相关的协议连接，实现通信。 而想要连上外部的互联网，那么据需要将无线网络中的一个相关的节点通过相关的协议连接，则模块的无线网范围内的网络节点或智能设备都可以访问外部的互联网。我本次主要研究模块间的互相通信及通信系统。

Design of Computer Communication System based on ESP8266

Abstract：With the development of modern society, the rapid development of wireless wi - fi technology and wireless internet of things, with the wide use of a variety of intelligent devices, our life is more convenient, simple and intelligent, most of the intelligent devices are closely related to wireless network technology. Esp 8266 is a complete and self-contained wi - fi network chip. as a kind of latest technology, it is developing rapidly. although it can't be applied to large-scale projects at present, the magic of this new chip is revealed everywhere in our daily life. We can use esp 8266 chip as the core design of a small local area network, so that intelligent devices within the scope of communication with each other, our modern pursuit of smart home can also be achieved. Esp 8266 chip has the characteristics of high integration, low power consumption, low cost and so on. especially in recent years, it has become one of the most popular chips. the research on wi - fi wireless network technology of esp 8266 chip in China is not very comprehensive, but the theory has been improved. we need to develop more practical applications. this technology has great practicability in the application fields of the internet of things, smart home and even some public places.

In this paper, based on the esp 8266 chip as the core of the wireless module, its at and SDK instructions are developed, and then with one or more modules reasonable installation design, because the esp 8266 module has AP + sta coexistence mode, we can use this feature to establish a small wireless local area network, so that the peripheral mobile terminals and other intelligent devices through the relevant protocol connection, to achieve communication. And to connect to the external internet, then according to the need to connect a related node in the wireless network through the relevant protocol, the module within the scope of the wireless network network nodes or intelligent devices can access the external internet. We mainly study the communication between modules and communication system.
