Abstract

The invention discloses a body temperature data acquisition and host serial port communication method based on ZigBee. The method comprises the following steps: after a ZigBee device is started and accesses a network, a host constructs a network access equipment topological graph; a ZigBee routing node periodically transmits a routing command frame to a ZigBee terminal node in a multicast manner; the ZigBee terminal node is used for measuring and packaging body temperature data frames; the ZigBee routing node generates an integrated body temperature data frame and sends the integrated body temperature data frame to the host; and the host receives and analyzes the integrated body temperature data frame. The power consumption is reduced, and the data transmission distance is long; the conversion from Zigbee to serial communication is realized; by integrating the body temperature data frames, the sending flow of the data frames can be reduced, and the processing of the host on the data frames of each ZigBee device is reduced, so that the congestion condition of the system is relieved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and more specifically relates to a ZigBee-based body temperature data collection and a serial port communication method of a host. Background technique [0002] ZigBee technology is a short-distance, low-complexity, low-power consumption, low-speed, low-cost two-way wireless communication technology, suitable for many traditional fields such as industry, agriculture, military, environment, and medical treatment. [0003] Medical testing in the traditional mode is very inconvenient for patients. Using wireless sensor network technology, through the corresponding human body electrical signal detection sensor, the data of human body signs can be measured. At the same time, through wireless data transmission technology, doctors can remotely monitor the patient through the control host The patient's physical condition can be checked at any time, and the alarm information can be accepted...
