ABSTRACT

This paper introduces the wireless intelligent central control system based on NRF and MCU and its implementation principle. It also puts forward a new resource management model, using today's relatively mature technology, a variety of sensors and user operation command to implement many practical functions such as remote control, automation, customization controls and so on.

In terms of the status quo of different methods for electrical control, differences in the actual control of the people demand, containing more electrical current situation more complicated or control of electrical appliances on the same occasion and the development of Smart Family, the intelligent central control system synthetically analyzes a variety of implementation for electrical control and intelligent control. It proposes a solution for wireless network control system based on global free 2.4GHz band and developes the corresponding peripheral circuits and supporting software. The intelligent central control system enables multi-functional intelligent central control system such as local control, intelligent control, custom control, network control, authorization control authority, optical compensation control, sensor feedback compensation control, data collection, analysis and feedback, the use of electrical support and intelligent connection.

We develop a complete wireless intelligent network control system solutions using the electronic circuit technology, computer technology, MCU technology, local area network technology, automatic control technology, optical physics and software platform.

The system mainly consists of MCU, NRF wireless module, transistor switches, data collection and feedback systems, network clock proofing system, LED display system, and computer testing procedures, etc. We use hardware and software to achieve all above functions. During the development of the system, we apply to a number of popular and traditional technologies, and the control principles and programs, draw on the results of previous studies of people or similar technology. In a word, we take full advantage of network information resources.
