With the development of the Internet and the advent of the 3G era, cloud computing and cloud networks surging out. Big data videos can be directly downloaded to the smartphone terminals for online viewing without any delay. In such a large environment, smart home technology is also undergoing earth-shaking changes. At this stage well-known brands of intelligent control products are still mainly wired, such as Schneider's C-BUS [1], ABB's I-BUS, Honeywell's H-BUS, Emerson's M-BUS, and Legrand TCL SCS-BUS, basically all the same fieldbus technology. With the maturity of civil RF wireless communication technology, such as WiFi and ZigBee [2], compared with the cable technology easy to install and disassemble, the network structure is simple, low cost and other obvious advantages. These advantages combined with the fast and large data storage cloud network transmission, will set off a vigorous wireless intelligent control revolution in the fields of lighting , appliances, security and other fields. Since August 23, 2012 Tencent WeChat public platform officially launched, the current number of users far more than 300 million in the city penetration rate is high, basically everyone is using WeChat. WeChat's new features are especially popular among contemporary youth. Convenient voice messaging delivers minimal traffic and saves money and is more cool than calling. Image transmission and then do not have to open an additional GPRS function, do not have to worry about the picture is too big hair can not go out, everything in the fingertips it is easy to complete. The technology described in this article is an intelligent control technology grafted on the WeChat public platform and its cloud network, hereinafter referred to as WeChat Intelligent Control. WeChat intelligent control technology is powerful, covering a wide range, can be used in the vast majority of intelligent control applications. In this paper, smart home, for example, will elaborate on its basic principles and its powerful features. The basic application of WeChat smart home in the smart home As shown in Figure 1, when the user sends text, voice and pictures and other information to the application through the mobile terminal or the WeChat on the computer, the message quickly passes through the 3G network Transmit to the router near the application side. Through the network cable TCP / IP protocol, the router then transmits the information to the WeChat Intelligent Control Gateway (a gateway specially designed for WeChat intelligent communication), which performs protocol conversion while data is being stored and quickly converts the information into New instruction [3]. The new directive in smart lighting, smart appliances and smart security applications have different manifestations and transmission methods, respectively, to discuss them below. First, the wisdom of WeChat intelligent lighting 1. First acquaintance ZigBee agreement Each family needs to use lighting to lighting, and the method of controlling the lamp at this stage is still the ordinary switch-based, a small number of infrared remote control, 315MHz and 433MHz RF remote control and other means. WeChat intelligent control system uses 2.4 GHz ZigBee protocol [4], and ZigBee uses on-demand routing AODV algorithm, you can easily achieve smart networking between smart devices, intelligent way, wireless transmission of information over long distances. As shown in Fig. 2 (a), when ZigBee remote control switch (No. 1 node) instructs the table lamp of node 12, according to the AODV algorithm, the instruction will be transmitted to node 3, then node 7, node 10, and finally to the table lamp , Table lamp according to the instructions to make the appropriate action, such as on, off, dimming, timing and so on. When nodes 2 and 7 are removed from the network, as shown in Figure 2 (b), when the command from node 1 is issued, the route will be recalculated. The new route will pass through node 3, node 6 and node 11 , Finally reached the node 12 lamps. Thus, as long as every two nodes can maintain communication between the nodes increase or decrease will not affect the communication. 2. Wisdom lighting principle (1) remote control mode When you are using your mobile phone for Weixin thousands of miles away and want to control lighting in your home, you can tap the keyboard to enter text or speak directly to send instructions to your home router over the Internet. The router then transmits the command to the WeChat intelligent control gateway through the network cable. As shown in Figure 3, the WeChat Intelligent Gateway will pack the command by the ZigBee protocol and radiate it out through the ZigBee antenna. Application end ZigBee wireless transceiver module [5] built in the lamp, the two adjacent lamps can communicate with each other. A large number of lamps and lanterns can form a lighting network. The network will find the optimal transmission route according to the on-demand routing algorithm AODV, and finally send the instruction to the target lamp. The target lamp will respond immediately according to the instruction, such as on, off, Dimming, timing, or return the current working status. (2) remote control mode WeChat intelligence control lighting system not only supports remote control lamps, but also fully compatible with close-range remote control. As can be seen from Figure 3, the close-end remote control of the main Weixin main control computer, computer, cell phone and remote control four. Their control methods are as follows: The first control. Mainly for WeChat intelligent control host, computer and mobile phone design, these three machines are equipped with the appropriate APP application software, you can directly on the house for each lamp on, off, dimming and delay and other operations. These three machines are through WiFi and router interworking, they issued a directive to the router through the network cable transmission to the WeChat intelligent gateway, the gateway and then instructions through the ZigBee antenna and lighting network transmission to the target lamp, the lamp made on request The corresponding action, and can return the working condition at that time. Visible in this control method, when the command arrived at the router, and remote control is basically the same way. The second control method, that is, remote control. Each luminaire has a location button on the remote control that corresponds to it, while function keys like dimming and delay are common. For example, if the lamp is turned on and the brightness is adjusted to 50%, the operation is to press the corresponding button on the remote control and the desk lamp. At this time, the function setting behind the desk lamp is for the desk lamp, and has nothing to do with other lamps. When the lamp receives the "name" command, it will reverse the current status, that is, if the original lamp is bright, it will be turned off now; if the original lamp is off, it will now be lit. After the lamp is lit, use your finger to directly click on the continuous dimming ring 50% of the position. This is the easiest way, without the need for routers and gateways and other equipment can easily control the lighting. Second, WeChat smart home appliances 1. Remote control mode Remote control is similar to smart lighting. When you use mobile phone or computer to send command to control home air conditioner, color TV and electric home appliances via mobile phone or computer, the order will be transmitted to the router in the home through the internet soon. Then the router The instructions transmitted through the TCP / IP protocol to WeChat Intelligent Gateway. As shown in FIG. 4, the WeChat intelligent control gateway repacks the instruction and emits it through the infrared LED. The infrared light encounters the reflection on the wall and finally the signal reaches the target appliance. The target appliance will make corresponding actions according to the instruction request.
