Abstract

The invention discloses a ZigBee-based heart rate data collection and a host computer serial port communication method, ZigBee terminal nodes collect heart rate data; form a ZigBee data packet and send it to a ZigBee coordinator, encapsulate the data transmission frame and send it to the host computer; judge the data transmission frame integrity and Correctness; the host encapsulates the data response frame according to the data transmission frame; the ZigBee coordinator forwards the data response frame to the ZigBee terminal node after receiving the data response frame; the ZigBee terminal node analyzes the data response frame after receiving it, and decides whether to resend the data transmission frame to the ZigBee coordinator. The invention realizes the functions of registering, updating and canceling the node addresses of each ZigBee terminal node. Through the data checksum function field, the correctness control of the data transmitted by Zigbee and serial port is realized, and the data that fails to be transmitted is retransmitted.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and more specifically relates to a ZigBee-based heart rate 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 at an...
