E. For stationary human detection, different body positions will have an
impact on the radar range, and the radar does not guarantee the maximum
range in all states.
5.2 Radar module operating modes
The radar module provides a comprehensive assessment of the current
status of people in the detection area after statistical analysis and
processing, and the user can make direct use of the results.
• Status operation mode
In this mode, the radar module periodically gives the presence and
movement status of people in the current radar detection area, the
main states are
1. No person present.
2. occupied, stationary.
3. occupied, active.
State operation mode, in order to environmental state judgment
accuracy, the radar module internal logic discriminate work, the radar
module state output logic is as follows.
A, radar equipment only when a state change is detected, the radar
has the corresponding state output; conversely, the radar remains
silent.
B, switching time ≤ 1s.
C, the radar switches from manned to unmanned state, requiring
multiple state confirmations and a switching time of ≥ 1 minute.
– Fall detection mode
In this mode, the radar module detects in real time whether
there is a fall action state within the detection range and
