INTRODUCTION

The fast development of electrical makes our lives become more and more convenient. Social demand for power supply capacity is becoming more and more strictly. On one hand is how to save power; On the other hand is how to meet the need of the society of electricity [1],this area has being one of the most intractable problem throughout the world, under the environment of internet of things intelligent socket realizes to consume capacity and feedback to the client's function timely. Functions and designing method of every module are introduced in this article in detail. Intelligent electrical outlet is an important part of intelligent household system, it can realize the power equipment monitoring easily, control and transmit data, communication technology uses the WIFI wireless technology; the technology is very suitable for household system communication network [2]. Intelligent socket of the original concept is for the purpose of security and protection, it is on the basis of ordinary socket extending more functions, such as its several protection functions against short circuit, overvoltage and lightning. Now smart socket is on the basis of these features combined with the functions of control circuit remotely, and the statistical power of connection on the socket device, through the network it will transmit the data to the users, this data provides a basis for

users make decisions wisely, it will make appliances become more intelligent eventually. Intelligent socket sets WIFI module internally [3], the client that can perform such operations on an ordinary smart phone through the socket. Through intelligent control can switch implement control other switch remotely, operation results will also return to the remote control. It plays a switch setting’s role. Intelligent socket mainly is used for household intelligent functions, it often matches with other electrical appliances. Intelligent sockets [4] can open circuit power supply, so as to control the electrical power supply or not; And intelligent host to communicate with each other to ensure the smart home system work normally. Some of the applications build on real time utility data will serve to user; others will analyze data in aggregate and serve policy and other decision makers. As a device can switch power supply of smart home, intelligent electrical outlet is the main medium of the future smart home life. Intelligent home has emerged with the development of computer science, communications, network and automatic control technology and so on[5]. It is also a great change brought up by advancement of technology. II.

The current and voltage detection are adopted resistance of sampling and current transformer sampling mode. G. The key module Key's main function is reset the socket or restore the factory settings. While the push-button is pressed less than 3 seconds, the system will reset when the socket is released then all devices will restart. While the push-button is pressed more than 3 seconds, the outlet will restore the factory default settings. To reset the socket, it will not affect the socket's runtime patterns, connecting network name, password, IP address etc., only to restart; To restore the factory default settings, the socket outlet will work in router mode [12], the socket will generate a WIFI network automatically, through the process of the client it can be connect to the Internet, and it also can set the socket parameters. H. Other modules Protection circuit is mainly be made of resistance and fuse. When the current is larger than the rated current, the fuse will disconnect automatically in order to ensure safety. If the voltage turns to unwanted fluctuations, and the transient voltage is greater than the specified voltage, through the resistance’s short circuit effect, it will force fuse disconnected to ensure the safety of electricity.

THE SOFTWARE DESIGN OF THE SYSTEM

The intelligent socket's essence is the socket as a carrier, and it accomplishes a remote smart home system through WIFI wireless [13].That is to say, If we have a super smart socket, no matter where we go, we can control the home air conditioning, lights, television and other household appliances just only with the phone, and we also can realize monitoring of family power and getting its analysis table.

The main program flow The purpose of designing of the system software [8]that is the server mainly be responsible for receiving a serial data from the port, after parsing, according to the inventory build listening socket, the client connection is accepted, maintain the client socket connection, At the same time it will send the received binary data stream to the client. Client application then launches three threads, including connection thread, receiving data thread, data processing thread which they will complete the functions such as data receiving and parsing, displaying and so on.

C. The specific process After initialing the server which will send out the radio instruction via a serial port at regular intervals, the received instruction socket will reply their own media access control (MAC) addresses to the server. In general, the server will decode after receiving the response of the frame socket. If the server received the socket for radio command response frame, then obtained the MAC address of the socket [16], and read the output socket's order through a serial port, got the socket’s power information instruction, after receiving the order, then it would send the response frame of power information to the server. D. The design of the PC client software The PC client authentication information is divided into three parts, they are user login interface, electricity information query interface, and actual data generated interface. This system establishes log-in boundary wish to realize the identification [17].It is shown in Fig.10.

Fig. 9. The physics topology structure between the communication server and its clients

Client applications send a connection request to the server, after setting up the connection the client will send request to the server for reading data, the server processes the request and sends data, the client then starts the corresponding thread for processing. The server establishes TCP/IP connection [14] with MCU firstly, then starts receiving data thread, being responsible for receiving the corresponding data; once the thread has processed the data and displayed then stored it in the database server. To monitor the client connection thread, it is responsible for establishing user socket and listening socket connection. The system uses the way to connect client applications to the server even in the face of application, platform or network failure. Once a connection is successfully made, the next task often is to read the data thread, read correspondent datum from the buffer, then write the information to a table, avoid the loss of data. View and update data for tables and views: Show as well as update data for tables and views [15]. B. Specific details For the serial port settings section, first of all, we need to make the serial clock can be set, in APB2ENR registers' configure the serial port 1.Then configure a serial port baud rate in USART_BRR registers. After then, we can go on serial port controlling on the USART_CR1 register. Then in the USART_DR register, data can be sent and received. Of course, a serial port state of nature can be read by USART_SR register.

Fig. 10. User login interface

Before being activated, the software read the information of interface elements, and generate graphical user interface (GUI) dynamically according to the information. The socket's equipment interface can add or delete a socket for users, and it also can control the state of the socket whether open or not. The electricity information that will be displayed in the Fig.11.Show the real-time electrical appliances [18]. The curved line chart draws a full time power. One of the two lines is the actual power, measured by the meter, and the other power is through the power measurement modules which are designed in this paper, As it can be seen clearly from the Fig.12.The two approximately equal, so the feasibility and validity of the molding methods offered [19] in this paper are confirmed in this paper.

an XML aware static reporting program can read that data directly. And it is displayed on the phone’s screen of the result. The users can control the condition of the sockets and devices through the electric state interface. And it also can control the opening and closing of the corresponding socket [20]. IV.

CONCLUSION

The automatic control system realizes the automatic control for intelligent electrical outlet by WIFI wireless communication technology and Internet technology. The system has much advantages in reliability and performance, It will better realize the automation and intelligent in control process. The next further job mainly realizes the intelligent socket all the way of timing control, it also can add a leakage protection switch to regular socket, eventually it will be able to make it more practical by analyzing and improving them. Later, we can add an LED display in the smart socket further, it can make convenient for users to intuitive interact and experience intuitively. So as to solve a common problem the current socket owned: the user does not know what the current state of the socket presently. However the display screen can solve this problem. Of course, on the other hand intelligent socket also need to keep the traditional control mode, so that the user can according to own needs to choose whether to let it "smart".
