Study And Developement On Intelligent Monitoring Of Clothing Based On Single Chip

The intelligent monitoring clothing (IMC) based on single chip is an importantresearch direction of body health monitoring, which has attracted researchers’ greatinterest in recent years. The IMC includes sevearl units such as data acquisition,signal processing, serial communication, client application software and clothingsubstrate. The whole system could collect the body surface signals by embeddedsensors, and monitors the physical condition with the help of computer technology.The studies of IMC involve in textile engineering, computer information system,electronics etc. Research results can be used for military defense, medical, health andother fields. In developed countries, IMC has been an important research content, butat home still in its infancy stage.The thesis’s content includes the establishment of monitoring system, design andimplementation of each sub-modules, testing the designed monitoring system in thecomputer simulation environment, using CAD software to produce the device andchecking the system’s function on human body.The designed colthing consists of hardware design, software design and systemtest. The hardware part includes signal acquisition modules, processing modules,serial communication modules and others. The signal acquisition module is based onsingle-bus digital temperature sensor DS18B20and pulse sensor HK2000-B; Theprocessing module is made up of band-pass filter circuit, A/D conversion circuit,microcontroller STC89C52, non-volatile RAM memory chips62256,8-bit latch74LS373, bidirectional bus transmitters/receivers74LS245and other relatedcomponents; The serial communication module employs voltage matching chipMAX232and RS-232interface. In addation, the software design is consist ofhardware drivers programm based on hardware design and client applicationprogramm for data analysis. The whole design should ensure that the entire systemcan work saftly, reliably and stably. Finally, this thesis takes temperature and pulse for example, compares the results of IMC with standard sensors to appraise the IMC’sworking performance in alert instructions, information temporary storage and serialcommunication.The results indicate that the IMC could exactly collect multi-pointtemperature value and pulse value, possessing temporary storage, transmission anddata analysis functions. The IMC is available to human health monitoring and remotemedical services system.
