| Difficult to society caused by the uneven distribution of medical resources doctor the high cost of social problems, for therapeutic purposes with the social development and people’s health, the concept of change:from the gradual change for the prevention of treatment of the supplemented by the concept of health. A remote medical care model: community health care for the secondary treatment center, the family bed for terminal care environment for patients, the medical model of care. This article in respect of remote healthcare monitoring system "must haves" in the medical model are discussed, studied and implemented the key technologies of the system (wireless sensor networks). The system consists of hospitals, community health care centers and family beds of these three components, the data transmission in these two basic modules of the district health care centers and family beds section, select the zigbee network as a network to collect physiological data of patients. This paper focuses on the zigbee protocol stack in the network layer and application layer, built on the basis of the CC2530communication module zigbee network’s smallest remote medical monitoring system, the system is coordinated by the network module, network routing module, the network terminal node The four components of the module and Monitoring Software. And places for different applications and application environment, design a specific network topology, the adaptability of the system more flexible and extensive. Add a non-contact infrared temperature sensor module, which the network terminal node module zigbee network to the patient’s body temperature transmitted to the host computer monitoring software and real-time display. After the definition of a transparent serial communication protocol, making the system flexible docking with the tripartite system.Finally, the research and design of the system are summarized, and telemedicine monitoring system further outlook. |
