1: Technical background With the rapid spread of network technology around the world, people's lifestyles are undergoing profound changes, consumers' needs are more personalized, humanized, and modernized, so that users can propose their own products. New requirements: Is it possible to remotely control your own products through the widespread Internet? Therefore, new ideas such as network industrial control, network home appliances and other products have emerged. The design idea of ​​network air conditioners has been born on the basis of this concept.
2: Design ideas and characteristics Network air conditioners, as the name implies, can realize remote monitoring of air conditioners through the Internet. In other words, users of network air conditioners can remotely control the home air conditioner by logging in to the Internet through any networked computer and mobile phone, including powering on, powering off, adjusting temperature, and so on. So how can we design such an air conditioner? One design idea is to embed a data transmitter, E-link, in the air-conditioning product, because E-link is a miniature Internet access module produced by Big Dipper Digital Information Co., Ltd., which is designed in a user-friendly secondary design. of. It can connect distributed serial devices or other various intelligent systems to the Internet, and use its internal TCP/IP, UDP and other network protocols and 10Base-T network interfaces to connect to the Ethernet to conveniently implement serial port networking. The E-link data transmitter has the advantages of compact size, low power consumption, low cost, and ease of use. Therefore, the air conditioner manufacturer only needs to embed the E-link on the original basis, and only needs to change the control part of the air conditioner slightly. This not only shortens the product development cycle for the manufacturer, but also reduces a large amount of manpower, material resources and capital investment, thereby greatly reducing the cost of the products it produces, and providing an opportunity for its products to occupy the air-conditioning market. The main functions and features of the network air conditioner embedded with E-link are as follows:
· Internet access. Home air conditioning equipment can be controlled remotely via the remote internet. Whether in the office or on a business trip, home air conditioning equipment can be controlled by computer, telephone, mobile phone, etc. Just like using OICQ to chat with friends, it's easy to talk to your home air conditioner.
· Make home air conditioning equipment interoperable. Thanks to the embedded E-link, all air conditioning units can be managed in a unified manner and decentralized.
· With new technology and era features, open network interface, with new network functions.
· Realize intelligent control of low cost, optimization, personalization and self-adaptation of air-conditioning equipment.
Since the popularity of home PCs provides the necessary conditions for home networking, this kind of network air conditioner has broad application prospects in ordinary families with the family's touch and the beginning of the family network movement in the modern sense. In addition, it can also be used in large shopping malls and intelligent communities to facilitate remote monitoring and unified management.

3.2: Internet access mode The following figure shows the block diagram of the network air conditioner accessing the Internet through the LAN. 
The following figure shows the block diagram of the network air conditioner accessing the Internet via Ethernet. 
Through several ways of accessing the network through the above network air conditioner, the user can send the instruction to the air conditioner at home without using the mobile phone or the handheld computer on hand, and the air conditioner at home will start to be in order.
In short, the air conditioner embedded in the E-link is different from the air conditioner in the traditional sense, because it is no longer an isolated appliance, has a fixed function, but can keep information sharing with the outside world at any time, and with the development of external technology Upgrade the update. E-link can be used not only in air-conditioning equipment, but also in household appliances such as refrigerators and washing machines. In this way, almost all household appliances in the family have ended the isolation of the original single function, forming a home network that is hand-in-hand, and each home network is connected to the Internet. Therefore, home appliance manufacturers can jointly set up a website, and every user of network appliances can log in to the website through any networked computer or mobile phone to remotely control the home network appliances. At the same time, it can be integrated with supermarket procurement, community service, home security, remote monitoring and other functions, making full use of the manufacturer's high-tech distribution and service network to provide consumers with various special services. Users will be able to control home appliances through the network, while manufacturers can provide better after-sales service. Therefore, E-link will set off an intelligent and networked revolution for China's home appliance industry in the new century, and bring profound changes to people's lifestyles.
