ZigBee network data transmission method for detection of baby incubator

Abstract

The invention discloses a ZigBee network data transmission method for the detection of a baby incubator, and the method comprises the steps that a coordinator builds a ZigBee network to wait for the joining of terminal nodes; the terminal nodes are powered on and joins in the ZigBee network, and the coordinator orders the terminal nodes joining in the network, and distributes different data transmission period parameters according to the serial numbers of the terminal nodes; each terminal node completes the detection of the baby incubator, and transmits the data to the coordinator through a data transmission period specified by the coordinator; the data transmission period is changed after each terminal node transmits the data for a specific number of times. According to the invention, through controlling the terminal nodes to transmit the detection data in different data transmission periods, the method can remarkably reduce the transmission conflicts caused by that the terminal nodes carry out the simultaneous transmission of data to the coordinator, and reduces the data retransmission energy consumption of the terminal nodes.

Description

technical field [0001] The invention relates to a ZigBee network data transmission method, in particular to a ZigBee network data transmission method oriented to the detection of an infant incubator. Background technique [0002] The baby incubator is one of the must-equipped equipments in the NICU ward of the hospital. It provides a mother-child womb environment for premature and critically ill babies, and its performance directly affects the life safety of the baby. The metrology department mainly tests its performance according to the "JJF 1260-2010 Calibration Specification for Infant Incubator". [0003] At present, the commercial products used for the detection of infant incubators mainly use wired methods to detect the five temperature points, and only use wireless methods during the data transmission process. On-site wiring is required, and the instrument is large and inconvenient to operate. For detection using ZigBee wireless sensor network, the problem of energy ...

Problems solved by technology

However, reducing the number of node data transmissions, the receiving end cannot obtain accurate data values, and at the same time it is difficult to judge the working status of the nodes; ZigBee network data transmission conflicts after the backoff retransmission method, but this type of algorithm focuses on the solution after the conflict, but does not start from Solve the problem of conflicts at the source; the synchronous dormancy strategy of the ZigBee network aims to achieve synchronous dormancy / wakeup of all network terminal nodes when they are idle, and reduce idle energy consumption, but its synchronous operation requires coordinated operation of the entire network, which is complex and complicated. Also significantly increases communication energy consumption

At the same time, in ZigBee network data transmission, all nodes use the same data collection and transmission cycle. When data transmission conflicts occur between nodes, the probability of conflicts in the next cycle is still random and uncontrollable.
