The smart health monitoring system with novel cache and network mechanism

A wireless portable bio-electricity signal real-time intelligent monitoring and display system supporting the free access of multiple monitoring is designed and realized, introducing wireless communication technology into the field of smart city such as smarthealth-care and smart home. A asynchronous cache mechanism is proposed to reduce the complexity and cost of the system, and it realizes the real-time collection and access to the existing wireless network. Meanwhile, the point coordinate function (PCF) is improved by bringing in priority polling and dynamical retransmission limit adjustment to ensure the orderly terminal data transmission and enhance the communication efficiency of wireless network. The results of NS2 simulation and the system test show that this design can achieve continuous wireless acquisition. Compared with the existing network using the mechanism of DCF and PCF, the transmission delay is reduced by 5% and 1% respectively. With the increase of the accessing devices, this design performs relatively better. The design can greatly improve the flexibility and practicability of the equipment and break the existing equipments out of the medical institution site due to its volume and wired connection, which is suitable for multi-user, mobile, wireless, remote diagnosis and the development record of the smart health supervision.
