User Manual

5.2 Operating Mode
After statistical analysis and processing, the radar module comprehensively
evaluates the personnel status in the current detection area, and the user can
directly use the results.
◆ State Operating Mode
In this mode, the radar module periodically gives the existence status and
movement status of personnel in the current radar detection area. The main states
include:
1) Nobody；
2) Somebody, static；
3) Somebody, active；
In the state operation mode, in order to judge the accuracy of environmental
state, the logic discrimination is carried out inside the radar module, and the state
output logic of the radar module is as follows：
A. Only when the radar equipment detects the state change can the radar have the
corresponding state output; On the contrary, the radar remains silent；
B. The radar switching from unmanned state to manned state (moving,
approaching and far away))is a fast switching state, and the switching time is ≤
1s；
C. When the radar switches from manned state to unmanned state, it needs to be
confirmed for many times, and the switching time is ≥ 1 minute；
◆ Sleep Detection Mode
In this mode, the radar module periodically gives the sleep state and respiratory
rate of personnel in the current radar detection area. The main states include：
4) Sleep quality evaluation：awake, deep sleep, light sleep；
5) In bed/Out of bed judgement；
6) Respiration rate statistics；
7) Respiration signal judgement：abnormal, short of breath, normal, abnormal
movement, abnormal rapid breath
In sleep detection mode, in order to judge the accuracy of related sleep state,
the radar module has specific installation mode and installation height restrictions：
D. When you need to use the respiratory rate statistics function in the sleep
function, you can only mount the radar at the top. Installation or inclined
installation, keep the position between the radar and the chest at 0.5m ~ 1.5m
