Energy Saving for mobile Iot appliances (1)

This seriesArticleThis paper introduces a set of solutions to achieve "energy saving for household appliances" based on the popular concept of "Iot. This section describes the concepts of "Iot" and "energy-saving household appliances" and provides current application scenarios.

1.Mobile Iot

Iot (The Internet of Things) Is defined by radio frequency identification (RFID (RFID), Infrared sensors, global positioning systems, laser scanners, and other information sensing devices, connect any item with the Internet for information exchange and communication according to the agreed protocol, A network that intelligently identifies, locates, tracks, monitors, and manages data."Iot"It is called the third wave of the world's information industry after the computer and Internet. Currently,USA,EU,ChinaAnd so on.

 

Iot is"Internet connected to things". There are two meanings: first, the core and foundation of the Internet of Things are still the Internet, which is an extension and expansion network based on the Internet; second, its user end extends and extends to any item and item for information exchange and communication.

Iot can be divided into three steps: 1. Identify object attributes, including static and dynamic attributes. Static attributes can be directly stored in tags, the dynamic attributes must be detected by the sensor in real time. Second, you must identify the device to read the object attributes and convert the information into a data format suitable for network transmission. Third, the object information is transmitted to the information processing center through the network (the processing center may be distributed, such as a home computer or mobile phone, or centralized, such as China Mobile'sIDC), The processing center completes Calculation of object communication.

Currently3GIn China, the mobile Internet era has arrived. In general, mobile internet is an organic combination of mobile communication and Internet. AndPCCompared with mobile devices, mobile devices have limitations in terms of screen size, processing capability, and data storage. However, mobile devices also havePCUnmatched advantages: small and lightweight, and convenient communication. Since the Internet has extended to mobile devices, mobile devices must also be part of Iot. With the development of mobile devices, their interfaces are becoming more and more abundant.USB, Wireless, suchWiFi,Bluetooth, Infrared,RFID,ZigBeeAlthough some of them require middleware support, integration already exists in the market.RFIDAnd mobile devices such as bar code scanners. With so many access technologies, mobile devices can play an important role in Iot.

 

2.Energy-saving household appliances

With the continuous progress of society and the continuous development of science and technology, people are more and more concerned about the earth on which we live. Most countries in the world have fully recognized the importance of the environment for our human development, energy conservation and emission reduction are also powerful measures being taken by most countries.

Energy Saving for household appliances is an important part of energy saving and emission reduction. Its purpose isPromote scientific electricity use and save environmental protection. Specifically,Energy Saving for household appliancesOne setAutomation solution for household power saving,Modeling and Analysis of household electricity usage can even be transplanted to industrial electricity usage,Monitors, counts, and analyzes the power supplies in the plant.

 

 

Energy-saving household appliances are part of smart home. After household appliances are embedded with sensors (temperature, humidity, power consumption, and so on), they become part of Iot. In terms of energy saving for household appliances, Microsoft has launched a solution. The address isWww.microsoft-hohm.com

,However, only users in the U.S. can enjoy free services. The process is to create your own account, and then enter some basic information about the home on the webpage, including the construction type, materials, and usage of home appliances, and thenHohmA copy is provided.EnergyThe report also provides energy-saving suggestions.Hohm communityShare your experiences with other users and learn how to save energy for other families. 

 

3.Application Scenario (User scenario)

Here we provide several application scenarios, including shopping guide, home andOfficeElectricity analysis, building andCommunityElectricity monitoring, smart grid, and so on.

3.1Shopping guide

Through a socket with a smallPadDisplays the electricity usage of electric appliances in real time, and analyzes various indicators and power-saving conditions of electric appliances used by users through charts.

3.2Family andOfficeElectricity usage analysis

By installing Smart Home sockets, collecting Electric Appliance information and uploading it to the server for analysis, you can analyze the home orOfficeUsage habits are displayed in charts and other forms.

 

3.3Building and community electricity monitoring

Take the family, eachOfficePowered by electricity analysis and the use of "cloud computing" technology, it is possible for the real-time dynamic management of hundreds of millions of electric devices.

3.4Smart grid

In the traditional power industry chain, power plants first generate electricity, then transmit it to substations through the power grid, and then to thousands of households through substations. To turn the power grid intoSmart grid, Step 1 firstSmart electric metersThis step begins. By installing Smart Home sockets, you can collect electricity usage information for household appliances, connect to the charging system of energy suppliers, and complete a series of work such as billing and payment.
