Description

Technical Field

[0001] The utility model relates to the technical field of physiological information monitoring equipment, in particular to a non-contact real-time monitoring system and device for human physiological information. Background Art

[0002] Non-contact physiological information monitoring equipment uses millimeter-wave radar to monitor changes in human breathing and heart rate and then monitor human health status. Therefore, the monitoring equipment should ensure the real-time and emergency nature of monitoring, and the processing system needs to meet the functional requirements of long-term monitoring and real-time monitoring.

[0003] In the prior art, the non-contact human physiological information monitoring system needs to be connected to a power source to achieve long-term monitoring and real-time monitoring, and the measured physiological data must be viewed on a mobile phone or PC. When the user is in a situation where it is inconvenient to charge or cannot connect to the network, the existing device is difficult to achieve continuous and stable physiological information monitoring and cannot provide a reference for disease prevention and diagnosis.

[0004] In the prior art, the utility model patent with the patent publication number CN221949799U discloses a vital signs monitoring system, including a shell, a millimeter wave transmitting unit, a millimeter wave receiving unit, a vital signs processing unit, a power supply unit and a vital signs data uploading unit are arranged in the shell, the vital signs processing unit is electrically connected to the millimeter wave transmitting unit, the millimeter wave receiving unit, the power supply unit and the vital signs data uploading unit respectively, and the vital signs data uploading unit is connected to the background server and the user terminal in communication. In this patent, the power supply unit is only a voltage conversion unit, which converts the city power into a low voltage to supply real-time power to the vital signs monitoring system. In the case of a power outage, the vital signs monitoring system cannot be used. Furthermore, the vital signs data uploading unit of this patent can only realize data transmission when the network is stable, and it cannot be used when there is no network. In addition, in this patent, the user terminal is a mobile phone or a PC computer, and it is impossible to view the vital signs data in real time on the device side. The defects of the above-mentioned existing technologies cannot guarantee the stability, real-time and emergency response of the vital signs monitoring system, and also limit the use scenarios of the vital signs monitoring system. For example, there may be no network outdoors, and it is embedded in the car computer to monitor whether the driver's heart rate and breathing are abnormal. The network is unstable while the vehicle is driving, etc. These defects are particularly unfriendly to patients with cardiovascular and cerebrovascular diseases.

[0005] There is another technical problem in the above-mentioned prior art, that is, there is no environmental monitoring data. According to medical prior knowledge, environmental temperature and humidity have a direct impact on the human body. If the environmental data is not combined, and only the results measured by the monitoring system are used for diagnosis and analysis, the results will be inaccurate. Utility Model Content
