Physical sign monitoring instrument based on wireless radio-frequency technology and monitoring method thereof

A physical sign monitoring instrument based on a wireless radio-frequency technology is used for acquiring human body physical sign data and transferring the data to a monitoring base station device in a radio-frequency communication mode and comprises a plurality of sensors, a sensor data acquiring module, a processor module, a Zigbee network communication module and a power module. The sensor data acquiring module is respectively connected with the sensors and the processor module and is used for sending the data acquired by the sensors to the processor module, the processor module is respectively connected with the Zigbee network communication module and the power module and used for processing, displaying and storing received data and transfers the received data to the monitoring basestation device through the Zigbee network communication module, and the power module provides power for the processor module. The physical sign monitoring instrument based on the wireless radio-frequency technology has the advantages of being low in power consumption, real-time and efficient in data transmission, strong in ad hoc network capability and high in transmission reliability.
