Design of Distributed Intelligent Physiological Parameter Monitor System Based on Wireless Communication Technology

According to disadvantages of conventional artificial monitor style or wire transmission monitor style, we adopt wireless communication network between field controllers and monitor central PC to design a distributed clinic medical intelligent physiological parameter data monitor system based on sensor technology, single chip microprocessor (SCM) technology, and visual instrument (VI) technology, etc. System can realize patient healthy condition monitor in real time, such as body temperature, pulse, ECG, respiratory, and so on. Sensors complete patient physiological signal acquisition, SCM AT89C52 analyzes and processes monitoring signal and transmitting to each department of hospital by wireless network. Through connecting each department monitor controller with professor monitor central station installed VI software LabVIEW by serial interface MAX485, distributed patient physiological parameter monitor system is carried out. This paper mainly introduces system structure, sensors, and wireless communication module design in detail. System can largely reduce virus infection rate between patients and nurses each other, largely save installation cost, and medical resource, etc, which has broad application prospect.
