After start electromagnetic signals and be scanned, the electromagnetic wave echo of collection reflection is sent to receiving module 420.
In the present embodiment, handover module 490 is switched over to the view shown in display interface.Shown in display interface
Three views of generation, handover module 490 then switches the indication range of view in display interface.The response of handover module 490 is carried out
The selection operation of views browsing, obtains the view that selection operation is selected in three views.And the display model of selected view
The amplification then in display interface is enclosed, the display indication range of other two view reduces, highlights selected view, make three
Individual view can show that user wants the view of display, target body can be looked for faster in handover operation.
Second embodiment
Referring to Fig. 5, Fig. 5 shows a kind of flow for vital signs display methods that second embodiment of the invention is provided
Figure.The step of vital signs display methods, comprises the following steps：
Step S201：Receive the electromagnetic wave echo-signal for the specific region that radar 200 is gathered.
In the present embodiment, step S201 can be realized by the receiving module 420 in first embodiment.Receiving module
The electromagnetic wave echo-signal of 420 specific region for receiving the collection of radar 200.Specific region is the court of scanning plane institute of radar 200
To region.Radar 200 is by gathering the electromagnetic wave echo-signal pair that the electromagnetic wave signal itself sent is reflected through object
Detected specific region.
Step S202：Electromagnetic wave echo-signal is handled, to judge that specific region whether there is with vital signs
Human body.
In the present embodiment, step S202 can be realized by the processing module 440 in first embodiment.Due to human body life
When depositing, the electric field that heartbeat can be produced, and therefore the electromagnetic wave echo that radar 200 is collected will produce corresponding change
Change.Processing module 440 can exclude other animals different from the electric field frequency produced by human body, to the electricity of radar 200
The progress of magnetic wave echo handles the vital signs for determining whether human body.
Step S203：When judging to there are the human body of vital signs, based on the electromagnetic wave echo signal form location drawing, ripple
Shape figure and signal moire pattern.
In the present embodiment, step S203 can be realized by the generation module 460 in first embodiment.Wherein, give birth to
Use into view is：The location drawing, for characterizing the position relationship between radar 200 and target body, wherein, position relationship bag
Include distance and angle between radar 200 and target body；Oscillogram, the power of the vital signs for characterizing target body；Letter
Number moire pattern, the environment for characterizing target body region.
Step S204：Display interface is generated, the location drawing, oscillogram and signal moire pattern are shown in display interface
Show.
In the present embodiment, step S204 can be realized by the display module 480 in first embodiment.Display module
480 generate display interface in terminal device 100, and three views that generation module 460 is generated are shown in display interface.Aobvious
Show in interface, three views are shown by default order and indication range.
Referring to Fig. 6, Fig. 6 shows a kind of another stream for vital signs display methods that second embodiment of the invention is provided
Cheng Tu.
Step S200：Sign on is sent to radar 200.
In the present embodiment, step S200 can be realized by the beginning module 410 in first embodiment.Start module
410 send sign on to radar 200.Radar 200 receives beginning electromagnetic signals after sign on and is scanned, and adopts
The electromagnetic wave echo of collection reflection is sent to receiving module 420.
Step S205：The view shown in switching display interface.
In the present embodiment, step S205 can be realized by the handover module 490 in first embodiment.Handover module
