Embodiment

[0019] Example: attached figure 1 It is a system structure block diagram of the present invention, the system has 10 wireless scanning nodes J1, ... J10, wireless scanning node and wireless convergence node 1 are all based on the CC2520 chip design of Texas Instruments, meet the Zigbee industry standard, work in the 2.45GHz frequency band, adopt Battery powered, tripod support, height adjustable from 0.3m to 1.5m. Place 10 wireless scanning nodes on the four sides of the bed 3 used to carry the human body, with a distance of 0.6m and a height of 13cm slightly higher than the bed, so as to ensure that the wireless signal passes through the human body as much as possible. The wireless aggregation node 1 and the general PC 2 are placed 3m away from the bed, and the wireless aggregation node 1 collects all the wireless link measurement information and sends them to the general PC 2; the respiratory frequency estimation algorithm running on the general PC 2 is based on link The re...

Abstract

The invention provides a respiration monitoring method based on wireless link information, belongs to the fields of health monitoring, patient and the old caring, wireless communication and wireless networks and relates to non-contact respiration monitoring method based on the wireless link information. The respiration monitoring method comprises the steps of utilizing multiple wireless links formed by multiple wireless scanning nodes and distributed on the periphery of a bed, monitoring periodic influence of human body respiration to the signal strength of the multiple wireless links to estimate a change cycle of the signal strength of the wireless links and then estimating respiratory rate of a human body. A system adopted by the respiration monitoring method consists of N wireless scanning nodes, wireless convergence nodes, a universal personal computer (PC), a respiratory rate monitoring method and the bed for bearing a human body. The respiration monitoring method adopts non-contact monitoring, does not need any facility installed on a monitored human body, enables the monitoring system to be humanized and is suitable for monitoring of infants and postoperative patients, and a non-contact monitoring technology has wide application prospect.

Description

technical field [0001] The invention belongs to the fields of health monitoring, patient and elderly monitoring, wireless communication and wireless network, and relates to a non-contact respiratory monitoring method based on wireless link information. Background technique [0002] Respiratory frequency monitoring has very important application value in people's daily life. A notable feature of many critically ill patients is that the respiratory rate fluctuates greatly. Therefore, hospitals need to monitor the respiratory rate of critically ill patients so as to effectively monitor the occurrence of emergencies. Obstructive sleep apnea syndrome is a common chronic disease with high morbidity and great harm. Using monitoring equipment to reliably monitor the patient's respiratory rate is of great significance to the clinical prevention and treatment of this disease. Dyspnea caused by turning over is an important factor that puts the baby's life at risk. Therefore, it is nec...
