Research On The Detection Technology For The Impact Force Field Of Shower Head With Wireless Transmission Technology

Speedy pace of life in today’s society, people shower heads have become increasingly demanding. In the shower process, the degree of comfort for the shower depends directly on the jet impact force field of a plurality of jet impact force on the human skin. Showerhead injector performance evaluation, the detection showerhead jet impact force and the jet impact force field is indispensable. Therefore designed a set for the nozzle jet impact force and impact force field detection system detected the shower nozzle jet impact force field distribution characteristics of the jet impact force field for the research of shower heads, get a better shower effect basis parameters; Lay the foundation for the overall performance of the better and more comprehensive evaluation showerheads; but also to provide a favorable reference for the research and development of new nozzle; to improve the showerhead design level and product quality, and even improve the quality of people’s lives.The topics in based on the understanding of the impact force and impact force field detection and wireless transmission technology research at home and abroad the status quo and development trend, the jet impingement force field detection technology based on wireless transmission showerheads. In research on showerhead jet impact force and impact force field characteristics under premise, construction of a detection system based on wireless network overall structure including the sensor detection circuit, a wireless transmitter terminal node module, single-chip system.Carried out the research on impact sensor and designing, for the shower jet splashing, multi-strand cross, temperature variations, etc the feature, and designing of an annular sensor; INA118 precision amplifiers, to achieve a detection signal conditioning. And sensor calibration method.Study and impact force field detection method based on wireless transmission. By comparison of the short-range wireless transmission technology, the study identified the ZigBee technology in wireless sensor networks. Building impact force field, the preparation of the communication rules. Impact force and impact force field detection characteristics and transmission requirements TI’s CC2530F256 as wireless communications chips designed I/O interface circuits, wireless communication protocol stack based on Z-stack programming the impact force field detection.
