0 Introduction the The country has proposed a "Smart grid" program and has developed a timetable for building a "strong smart grid". "Smart Grid" will achieve the "power flow, information flow, business flow," the integration of a high degree of integration. Intelligent substation is an important foundation and support of strong smart grid, it is in the center of the smart grid hub position. On the receiving of high-voltage power grid input, the next to complete the substation and the u

Modern security monitoring is increasingly being valued. It is generally composed of image acquisition, transmission and storage system. The use of high-precision cameras with advanced image processing technology and transmission technology. Although its security monitoring performance is very good, but there are large investment costs, real-time alarm performance is poor. Large amount of data, the shortcomings of concealment. In view of these shortcomings, some applications can also use infrare

(Supporting source code , software , development boards and other resources, can be the blog of the same name QQ group: Napoleon 940911) This section and the next section will tell about the low power consumption of ZigBee terminal equipment. This section focuses on the low-power theory portion of ZigBee technology based on the CC2530 chip. First, the application of the background " Power consumption " is

Writing a pleasing engineering document is a difficult task. If you want to write well, not only to use the tool (using the right tools), pay attention to writing, but also have to devote a lot of time, really is a very difficult thing. But, if really write good, also is good great Yan: can let a person understand "why so design", namely "know it more know its why", also can peel off some trivial details, let more not so much time and energy, or the background knowledge insufficient friend, to t

A project recently involved in planning requires a large amount of ZigBee (about 5000) data collection. Because of the wide-area layout and the mesh network architecture, many nodes are so-called routing nodes, which raises a problem. The routing node usually needs continuous power supply, because only batteries can be used for power supply in the field, this is in great conflict with the Requirements for battery use for one to two years. Therefore,

Wireless networks are a huge family. Various wireless technologies have different application aspects. Since its development, wireless networks are also different. In addition to Bluetooth, the short-distance wireless Branch also has a wireless ZigBee technology. Wireless ZigBee technology is a new wireless network technology with low complexity, low power consumption, low data rate, and low cost. It is a t

ZigBee defines 3 types of devices, each of which has its own functional requirements: 1. ZigBee Coordinator (Co-ordinator), is a device to start and configure the network, is the central node of the network, a ZigBee network is only allowed to have a ZigBee coordinator; 2. ZigBee
