In, the human body signal that human body signal collector 105 acquires can be synchronized with the big ground of the same standard.
Fig. 3 b is a kind of night self-starting human perception card structure schematic diagram that the utility model embodiment three provides, described
Night self-starting human perception card can be used for receiving the human body signal that human body signal picker 105 acquires at night, and according to institute
It states human body signal and generates the triggering level signal for carrying out personnel's Image Acquisition for starting image capture module 106.Such as Fig. 3 b institute
Show, is provided with third human perception circuit 301b and third connector 302b, third on the night self-starting human perception card
Human perception circuit 301b includes the first human perception circuit 201 and ambient brightness aware circuit 307b.
Wherein, ambient brightness aware circuit 307b and human body signal control chip 305b are electrically connected；
Ambient brightness aware circuit 307b is sent to human body letter for generating starting control signal or closing control signal
Number control chip 305b；
Human body signal controls chip 305b, enters power-up state for controlling signal according to the starting, alternatively, according to institute
It states closing control signal and enters off-position.
Wherein, ambient brightness aware circuit 307b, which refers to, is arranged on third human perception circuit 301b, for according to ring
Border light luminance generates the circuit of starting control signal or closing control signal.Starting control signal refers to for starting human body letter
Number signal that works on power of control chip 305b, closing control signal is to be used to indicate human body signal control chip 305b power-off to close
The signal of machine.Optionally, ambient brightness aware circuit 307b is bleeder circuit, including fixed resister and photodiode, institute
It states starting control signal and closing control signal is branch pressure voltage signal；I.e. by by fixed resister and photodiode string
Connection, using the other end of fixed resister as fixed voltage input terminal, and using the other end of photodiode as branch pressure voltage
Output end, as a result, according to the light sensitive characteristic of photodiode, the voltage of the exportable different voltages value of branch pressure voltage output end is believed
Number, i.e., the described branch pressure voltage signal.Optionally, when branch pressure voltage value is lower than setting voltage value, branch pressure voltage signal is to close
Signal is controlled, human body signal control chip 305b is judged as daytime, and power-off shutdown；When branch pressure voltage value is higher than setting voltage value
When, branch pressure voltage signal is starting control signal, and human body signal control chip 305b is judged as night, and works on power.
Specifically, ambient brightness aware circuit 307b generates starting control signal or closes and controls according to ambient brightness
Signal, and it is sent to human body signal control chip 305b, human body signal controls chip 305b and is judged as according to starting control signal
Night simultaneously works on power, alternatively, being judged as daytime and power-off shutdown according to closing control signal；By human body signal collector 105
Conducting wire and human body signal input terminal 303b is cooperated to be electrically connected by third connector 302b, as a result, when human body signal controls core
When piece 305b works on power, human body signal is inputted by third human perception circuit 301b by human body signal input terminal 303b；People
Body signal controls chip 305b and receives the human body signal, and obtains the reception duration of the human body signal, meanwhile, according to delay
The delay control signal of control circuit 306b transmitting generates reference time length, then grows up when judging the reception of the human body signal
When reference time length, the triggering level signal is generated according to the human body signal；Master control chip 104 is passed through the
Three connector 302b cooperate conducting wire and triggering level output end 304b to be electrically connected, and pass through triggering level output end 304b as a result,
Triggering level signal is exported from third human perception circuit 301b, and is sent to Master control chip 104.
Illustratively, Fig. 4 b is that a kind of night self-starting human perception card circuit that the utility model embodiment three provides connects
Connect exemplary diagram.In this example, the human body signal is human infrared signal；Human body signal collector 105 is passive pyroelectric
Infrared probe；Third connector 302b is row needle J2；It is human body infrared induction IC chip that human body signal, which controls chip 305b,
AS083；Delay control circuit 306b is bleeder circuit, including slide resistor RP1 and divider resistance R2；The delays time to control letter
Number be branch pressure voltage signal, the triggering level signal be 3.3V high level；Ambient brightness aware circuit 307b is bleeder circuit,

As shown in Figure 4 b, the human body signal input terminal 303b of the night self-starting human perception circuit runs in the needle of needle J2
Foot 1 (SA1), triggering level output end 304b run in the stitch 4 (SA2) of needle J2.Filter capacitor C1 mono- terminates human body infrared induction
The PIR pin of IC chip AS083 and the stitch 1 (SA1) for arranging needle J2, another termination GND are red by passive pyroelectric to filter out
High-frequency harmonic in the human infrared signal of outer probe acquisition, keeps human infrared signal acquisition more accurate.Biasing resistor R1 connects
Meet the amplifier in human body infrared induction IC chip AS083, another termination GND, for adjusting base current.Human body infrared incudes IC
Passive pyroelectric infrared probe in the PVCC pin output 2.4V voltage supply master board 101 of chip AS083, filtered electrical
The public termination PVCC pin for holding C2, C3 guarantees the steady of power supply for filtering out the higher hamonic wave and low-order harmonic in 2.4V voltage
It is qualitative, ripple interference is filtered out, the human infrared signal for acquiring passive pyroelectric infrared probe is more accurate.Human body infrared sense
The end CD of IC chip AS083 is answered, the cathode of photodiode D1 is connected, the anode connection divider resistance R3's of photodiode D1
One end, the R3 other end connect the 2.4V signal output end of human body infrared induction IC chip AS083, i.e. PVCC pin.D1 and R3 structure
At a bleeder circuit, when the end CD incoming level is lower than 1.0V, controller does not work and (is judged as daytime), when the end CD inputs electricity
When putting down higher than 1.0V, controller works (being judged as night), to change and trigger ambient brightness corresponding to critical value out, it is only necessary to
Change the resistance value size of R3, R3 resistance value is smaller, and ambient brightness value corresponding to critical value is bigger.Divider resistance R2, sliding
Rheostat RP1 forms bleeder circuit, by adjusting RP1, can adjust the defeated of the port TCI of human body infrared induction IC chip AS083
Enter voltage, the port TCI is timing controlled input terminal, and it is raw to can adjust human body infrared induction IC chip AS083 for the end TCI voltage change
At reference time length, thus can realize, the personnel in gate inhibition's visual range, its be detained or duration of hovering reach reference time length
Afterwards, door access machine can be triggered start automatically and take pictures or camera function.Human body infrared incudes the RST pin floating of IC chip AS083,
Into use state, VSS pin meets GND, and OUT pin is triggering level signal output end, is usually low level, works as human body infrared
When induction IC chip AS083 detects that the reception duration of human body signal meets or exceeds reference time length, OUT pin exports 3.3V high
Level, and pass through the stitch 4 (SA2) of JI, 3.3V high level is transferred to the PB9 foot (Signal-IN) of Master control chip 104.
When Master control chip 104 detects 3.3V high level, camera camera function can be started, and by image data, by network interface/
WIFI is uploaded to associated monitor terminal, such as monitor backstage, cloud, monitor cell phone application end.It should be noted that entire
Human perception card circuit, it is the benchmark of human body signal acquisition, to make in circuit, human body signal that one, which is digitally GND,
The human body signal that collector 105 acquires can be synchronized with the big ground of the same standard.
