Objective: With the growing aging, elderly care demand is constantly increasing. In order to solve the problem of appropriate elderly care, the working principle of the monitoring system for the physiological information based on msp430 SCM and Android system is detailedly introduced in this paper. Methods: With the msp430 as the core, the collection terminal is equipped with the sensor modules, such as temperature sensor, blood oxygen sensor, and so on. Using sensor technology and embedded technology, physiological information collection terminal is designed in this paper. A fall detection is used in the design,when old people fall, the system can inform the custodial staff in time to prevent a situation that the treatment is not timely, The collection terminal uploads the collected information to the smart phone with android system by Bluetooth. Establish the physiological monitoring system for elderly by uploading data to the server through the android system. Results: The system is tested.Tests show that the system can accurately collect data. The range of temperature error is from-0.3℃ to +0.3℃, the measurement of oxygen saturation is in the normal range which is between 95% and 98%, fall detection accurately detects the fall situation. The system meets the testing standards, and achieves the desired effect. Conclusions:The system can monitor the physiological information of the elderly, for example the oxygen saturation and body temperature. The system can alarm when old people fall down, and make that the elder can be treated in time. The system has good scalability and broad application prospects.
