Pyroelectric effect refers to the electric charge release phenomenon that polarization intensity changes and shown with temperature, is macroscopically temperature
Change makes to occur voltage at the two ends of material or produces electric current.It is exactly the class sensing with pyroelectric effect that heat, which releases inductor,
Device.
Heat releases inductor and FET is introduced in structure, and its object is to complete impedance conversion.Because thermoelectricity member is exported
Be charge signal, can not directly use, thus need to be converted into voltage form with resistance.Therefore the N-channel knot introduced
Type FET should be connected into common leakage form to complete impedance conversion.Heat releases inductor by sensor measuring member, interferometric filter and field
The part of effect pipe adaptation three is constituted.High thermoelectric material should be made to certain thickness thin slice during design, and plated on its two sides
Upper metal electrode, then powers up and it is polarized, and pyroelectricity detection member has so just been made.
The infra-red radiation for detecting and receiving is transformed into faint voltage signal by detecting element, through in probe
Outwards exported after FET amplification.In order to improve the detectivity of detector to increase detection range, typically in detector
Front install a Fresnel Lenses, the lens are made of transparent plastic, and upper and lower two parts of lens are respectively divided into some etc.
Part, a kind of lens with special optical system are made, it and amplifying circuit are engaged, and can amplify signal.
Fresnel Lenses utilizes the special optical principle of lens, and side produces " blind area " alternately changed before the detectors
" highly sensitive area ", to improve its detection receiving sensitivity.When someone walks out-of-date before lens, the infrared ray that human body is sent is just
Constantly alternately from " blind area " entrance " highly sensitive area ", thus make the infrared signal received with dynamic impulse form
Input, so that its strong energy amplitude.
Connected between detection camera master control borad 201 and equipment 202 by serial ports.
Serial line interface abbreviation serial ports, also referred to as serial communication interface or serial communication interface (being often referred to com interface), are to use
The expansion interface of serial communication mode.
Serial line interface (Serial Interface) refers to that ground order of data one is transmitted, and is characterized in communication line
Simply, as long as a pair of transmission lines can just realize two-way communication (directly can be used as transmission line by the use of telephone wire), so that significantly
Cost is reduced, telecommunication is particularly suitable for use in, but transfer rate is slower.Every data of one information are by by turn in order
The communication modes of transmission are referred to as serial communication.The characteristics of serial communication is：The transmission of data bit, step-by-step order is carried out, minimum
A transmission line is needed to complete；Cost is low but transfer rate is slow.The distance of serial communication can be from several meters to several kms；According to
The direction of transfer of information, serial communication can be further divided into three kinds of either simplex, half-duplex and full duplex.
Current serial ports is used in industry control and measuring apparatus and section communication equipment.
Two kinds of most basic modes of serial communication：Synchronous serial communication mode and asynchronous serial communication mode.
Synchronous serial interface (Synchronous Serial Interface, referred to as：SSI it is) a kind of conventional industrial
Communication interface.Asynchronous serial refers to (Universal Asynchronous Receiver/Transmitter, abbreviation：UART)
Universal Asynchronous Receive/transmission.
UART is a parallel chip of the input as Serial output, is generally integrated on mainboard.UART includes Transistor-Transistor Logic level
Serial ports and RS232 level serial ports.
Serial line interface is divided including RS-232, RS-422, RS485 etc. by electrical standard and agreement.
Serial line interface RS-232 is also referred to as standard serial port, a kind of the most frequently used serial communication interface.Use at present and be reduced to 9 cores
D type sockets.
RS-232 takes uneven transmission means, i.e., so-called single-ended communication.Due to its transmission level and the difference for receiving level
Only 2V to 3V or so, so its common mode inhibition capacity is poor, along with the distribution capacity on twisted-pair feeder, its transmitting range is to the maximum
About 15 meters, flank speed is 20kb/s.RS-232 is designed for point-to-point (only using a pair of receiving and sending equipments) communication.Institute
Communication between local device is adapted to RS-232.Pass through in the present embodiment between detection camera master control borad 201 and equipment 202
Serial ports RS-232 connections.
Moving heat source 204 does linear uniform motion between two points.
Equipment 202 releases inductor in camera bellows and the different images of the induction curve of moving heat source by analyzing the heat
Quality, detect the performance of the detection camera master control borad 201.
Equipment 202 is main control computer or PC with serial ports.
When heat releases inductor and senses human motion, the intensity of sensing can be shown in equipment by the curve of change, bent
The intensity of the bigger sensing of amplitude of line is bigger, and identical range-amplitude display is bigger, and heat releases the higher of the sensitivity of inductor.Curve
Changes in amplitude embodies the sense intensity that heat releases inductor, bigger by identical range-amplitude display, and heat releases the sensitivity of inductor
Higher principle releases the induction sensitivity of inductor to test heat.
Under camera bellows environment, the sensing that test heat releases inductor is interval (i.e. ambient noise), the curve of induction change
Amplitude is more low better, under moving heat source, and test heat releases the induction sensitivity of inductor, and the profile amplitude of induction change is got over
It is high better.
