[Abstract]:In order to solve the problems of wireless detection data conflict and energy consumption in baby incubator, a ZigBee heterogeneous data transmission method is proposed. By analyzing the network topology characteristics of the baby incubator wireless detection system, the data transmission cycle of each terminal node of ZigBee is assigned to different data transmission parameters and changed alternately periodically. Reduce the conflict of random data sent by multiple terminal nodes to the coordinator, and then reduce the conflict of wireless data transmission and reduce the energy consumption. The data transmission cycle parameter equation of the different period transmission method is established and derived. the design example of the data transmission method and the hardware and software design of the wireless detection system of the baby incubator and the energy consumption test of the terminal node are given to realize the temperature of the baby incubator. Humidity and other parameters detection, in practical use to verify the feasibility of the method and detection system.
