Awning Intelligent Wireless Control System

There are hundreds of awning production enterprises in China, but the production performance cannot meet the overseas customers'needs and the domestic demand for high-end market,the customer can only choose the overseas advanced automatic control system production to improve the brand, quality and the performance of the awning, but the price is expensive. So it is vital significance to study the awning intelligent control technology, which has the independent intellectual property rights.According to the comprehensive analysis and research to the domestic and foreign awning intelligent control system, this thesis focuses on the analysis of the embedded control household network, the latest control method which based on the technology of wireless, and the deep research of the wireless code's anti-jamming ability has been made.lt achieves the wireless intelligent system which can be stable and reliable intelligent control and remote monitored by users at any time.The following sections will be discussed in this paper:First, combined with the domestic and foreign backgrounds of the awning control system, the general composition of the Smart Home wireless network system and the control system in the position of the Smart Home are analyzed. through the analysis of the characteristics of the traditional Smart Home, the limitations of the Smart Home system in current domestic market are expounded.Then the system framework of shading technology and related key technology are analyzed and compared, and the current development trend of awning control systems that based on wireless technology is pointed out, and wireless control of the system is comprehensive studied.Secondly the awning intelligent wireless control system and its working principles are introduced, the workflow of the wind-light sensor, the telephone remote controller, as well as remote controller are analyzed. A kind of wireless automatic control system which takes STC single chip microcomputer as its core control portion is proposed. Under each functional module's coordination, this system can automatically or hand control awning's open and close through the master-control unit's control.According to the problems of jointing of multiple devices, the satisfied equipment's code wireless launch's control and realization is proposed. the CRC check coding algorithm is improved. The wireless control to remote devices by the phone is selective analyzed. It discusses the wireless phone working principle and the key technology of coding calibration, and detailed designes the sound detection, the simulation picked electric circuits, double audio decoding, voice circuits, coding wireless data launch receiving circuits, etc.The remote control device based on wireless and PSTN combination is finally realized.Finally, it carries on jointing testing to the awning control system, analyzes the system's function and anti-jamming ability,the system debugging results are given,it makes very good reflection on experimental repetition,and the expected goals are achieved.
