Description of the drawings
Fig. 1 is system search coverage schematic diagram；
Fig. 2 is system connection diagram.
Specific implementation mode
The present invention is described in detail With reference to embodiment.
Infrared ray domestic safety prevention system of the present invention, after Raspberry Pi is connected with human body infrared detection module by internet
Platform server, the data with alert that the stranger detected swarms into are transmitted on specified server, are transmitted after data store
To mobile phone, user is made to know family stranger.Fig. 1 is search coverage schematic diagram of the present invention.
The amplitude output signal of Thermoelectric Infrared Sensor is smaller, frequency is low, detecting distance is short, in order to make it have reality
With value, we use two measures:(1) it installs one piece of hemisphere face Fresnel Lenses before Thermoelectric Infrared Sensor additional, matches
It closes PIR and improves its receiving sensitivity.(2) cooperation amplifying circuit amplifies signal.10m even farther one can thus be measured
The activity of the people of point.
In addition after lens, due to the special construction of lens, can be generated with received signal alternate " blind area " and " highly sensitive
Area ".When someone walks out-of-date before lens, the infrared ray that human body is sent out is just constantly by " blind area " entrance " highly sensitive area ".In this way
The infra-red radiation of generation is put into Thermoelectric Infrared Sensor, to improve its receiving sensitivity, makes its command range
It is increased within 8 meters or even farther distance.The infrared heat caused by Thermoelectric Infrared Sensor detects human motion
When changing, and being transformed into electric signal, amplified by frequency-selecting, compared, delay timing, controlling the links such as pulse output, will controlled
Signal processed is sent into control circuit, then generates the sufficiently large control signal of amplitude to trigger bidirectional output port, is allowed to conducting and band
Dynamic alarm or the action of other actuators constitute complete monitoring system.
(1) parameter setting Raspberry Pi of the present invention is at wireless connection conditions；
sudo nano/etc/wpa.conf
network{
Ssid=" wireless network names "
Wep_key0=" wireless networks password "
}
(2) as shown in Figure 1, connection Raspberry Pi and the human body infrared detection modules of HC-SR501, three lines of module connect respectively+
24 foot of 5v, gpio, the Raspberry Pi interface of gnd；
By the pir sensor used, there are three pins for we：Ground connection, numeral output and 3-5Vdc inputs.When idle, if
Movement is not detected, digital output signal will stay in that low.But when detecting movement, digital output signal is by pulse height
(3.3V)。
(3) wire jumper setting to the position " L " will be generated into primary (not reproducible) triggering.It, will be when wire jumper is located at this position
Sensor events enable sensing after occurring, and can thus continue detection movement.If can't detect movement, output will be locked as
Low 3 seconds.
Wire jumper setting to the position " H " will be generated into repeatable triggering.When wire jumper is set to " H " (acquiescence) position, it will occur
(that is, once output is height) disabling sensing after sensor events.
(4) it programs：
HC-SR501Device is created to control it using equipment access API
A function for initializing and activating GPIO24 feet is created using DveiceManagerAPI and GPIOPinConfig
Device name：0
Pin numbering：GPIO 24 (specified by pinGPIO)
Direction：Only input
Pattern：Drop-down
Trigger：Rising edge
Initial value：false
Wait for that PIR is initialized Deng 3 seconds
A method is created to receive the class defined, supports infrared radiation detection to close and open, and calculate detection
Method setting is reasonable, makes point-to-point image using detection signal, then shown by the desktop of Raspberry Pi, calls Internet Server
Network interface is sent the SMS to image transmitting to Service-Port on mobile phone by network using existing technology.
(5) human body infrared wire module, adjustable sensitivity are adjusted
Adjustment sensitivity potentiometer promotes sensor distance clockwise, then shortens distance counterclockwise
Adjustment delay potentiometer increases the delay of sensor clockwise, then reduces delay (6) detection counterclockwise
When idle, if it is detecting that human motion, digital output signal will keep low level, and not send out alarm.Detection
To when human motion, digital output signal sends a warning pulse height.
This experiment is using HR-SR501 human body induction modules as sensing element.With reference to the above Raspberry Pi and HR-
The circuit diagram of SR501 human body induction modules composition.The external 5V power supplys of the sensor, inside are equipped with Fresnel lens, detection zone
For spherical shape, effectively warning distance is 3~6m, and deflection is<100 degree of obtuse angles.When the hand of human body or certain part of body are red
In outside line detection zone, the infrared ray that RPI is sent out passes through since human body hand or body block and be reflected into infrared receiver tube
The micro computer of BIOSS001 treated signal is sent to OUT signal output, according to the instruction of OUT by being edited in Raspberry Pi
Program calculates, and to send out alarm 60s on MISO pin movement orders to loudspeaker, and internet remote alarm is triggered after the 7s that is delayed
Program, mobile phone receive short message immediately；When the hand or body of human body leave infrared induction range, RIP does not receive signal, the ends H
Mouth passes through internal spring and carries out repeated trigger control.
The above is only the better embodiment to the present invention, not makees limit in any form to the present invention
System, every any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
