60G Millimeterwellenradar berührungslose Wahrnehmung der Atemfrequenz und Herzfrequenz des Personals Radar, IR60BH1A
BESCHREIBUNG
Das IR60BH1A-Radarmodul ist ein Radarerkennungsmodul, das auf der Millimeterwellen-Doppler-Radartheorie basiert und die 60G-Millimeterwellen-Radartechnologie verwendet, um die berührungslose Wahrnehmung der Atemfrequenz und Herzfrequenz des Personals zu realisieren. Dieses Modul basiert auf der verbesserten Theorie der Doppler-Radarsignalverarbeitung und erreicht eine drahtlose Wahrnehmung des Status des Personals an einem bestimmten Ort durch die synchrone Erfassungstechnologie von Doppler-Parametern der Personalbewegung und physiologischen Parametern des Personals.

OPERATING MODE
The beam coverage of radar module is shown in. The radar coverage is a three-dimensional sector area with 80 ° horizontal and 80 ° pitch.
Due to the influence of radar beam characteristics, the radar operates far in the normal direction of the antenna surface, but the operating distance deviates from the normal direction of the antenna will become shorter.
When the radar is installed on the top or obliquely, the radar action range will be reduced due to the influence of the radar beam range and effective radiation space, which requires additional attention during use.
INSTALLATION METHOD
Radar detection is based on the undulating movement of the large body surface caused by respiratory rhythm and the undulation of the human chest and back will become obvious. Therefore, the radar needs to be installed facing the chest or back of the human body.
Based on the radar action mode, the following installation modes are mainly considered:
(1) Top-mounted
For people that are bedridden or with sleep needs, it is recommended to install on the top: the radar beam is vertically downward facing the human body, and the center of the radar beam is facing the human chest.
In this installation mode, the distance between the radar and the human body to be measured is required to be ≤ 2m
(2) Oblique-mounted
When the radar is installed obliquely, it needs to be fixed on the wall or beside the bed. The radar is installed obliquely: the radar beam irradiates the human body obliquely, and the center of the radar beam is facing the chest of the human body.
In this installation mode, the radial distance between the radar and the human body to be measured is required to be ≤ 2m.
(3) Horizontal-mounted
The radar is installed horizontally, and the radar is fixed on the wall or placed on the desktop: the radar beam irradiates the human body in a positive direction, and the center of the radar beam is facing the chest of the human body.
In this installation mode, the radial distance between the radar and the human body to be measured is required to be ≤ 2m.
