Description
Technical field
The invention belongs to detection technique field.It is specifically related to the light intensity detecting system of a kind of novel framework.
Background technology
LED, as 21 century green illumination new light sources, has the advantages such as brightness height, life-span length, energy-conserving and environment-protective；The most domestic
Form 7 National Semiconductor illuminating engineering industrialization bases, become big producing country and the big export country of world's electric lighting, as
Semiconductor lighting product is detected the importance become during testing laboratory builds by what.
Light intensity is a base attribute of light source, and it considers sense of vision factor and the optical characteristics of people, is also light source simultaneously
Attribute；Light source intensity detection is one of project of photoelectricity enterprise primary study；In the situation that China's Pressure on Energy is increasingly severe
Under, accelerate the development of new light sources industry, promote energy-saving and emission-reduction, ensure the quality of new light sources product, be the certainty of sustainable development
Select.
Summary of the invention
Technical problem: the problem existed for above-mentioned prior art, the present invention provides the light intensity of a kind of novel framework to examine
Examining system.
Technical scheme: the present invention relates to the light intensity detecting system of a kind of novel framework, including host module, intensity collection
Module, from machine core controller and display module；System host application C# programming language realizes program to programmable power supply, PLC, light
The control of strong plate and data receiver, process, and carry out light intensity demarcation and secondary calibration, it is achieved data are at polar coordinate, rectangular coordinate
Show with in data list.
The light intensity detecting system of a kind of novel framework, is characterized in that:
Described intensity collection module is made up of signal conditioning circuit, A/D converter, MCU, reset circuit and PSU power module.
The described STM32F107 chip from the employing of machine core controller with ARM CortexM3 as kernel.
The method have the advantages that
1, present system uses master-slave mode light intensity detecting system test result accurate, can be widely applied to light source and illumination
Detection field.
2, the data received are done the form that optimization processes and is converted to needs, the curve of sample test by present system
Show in polar coordinate, rectangular coordinate and data list respectively, it is simple to data analysis.
Accompanying drawing explanation
Fig. 1 is present system overall structure block diagram.
Fig. 2 is intensity collection circuit block diagram in the present invention.
Fig. 3 is flow chart of data processing figure in the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment further illustrates technical scheme.
As it is shown in figure 1, the light intensity detecting system of a kind of novel framework, including host module, intensity collection module, from machine
Core controller and display module；System host application C# programming language realizes program to programmable power supply, PLC, the control of light intensity plate
System and data receiver, process, and carry out light intensity demarcation and secondary calibration, it is achieved data arrange in polar coordinate, rectangular coordinate and data
Table shows.
As in figure 2 it is shown, described intensity collection module is by signal conditioning circuit, A/D converter, MCU, reset circuit and PSU
Power module forms；Analog to digital conversion circuit uses AD7356 chip, due to the operating characteristic of analog digital conversion, it may appear that aliasing is existing
As, and AD7356 chip itself carries frequency overlapped-resistable filter, the beneficially design of circuit；Additionally, built-in defeated of converter chip
Enter clamping protective circuit and can withstand up to ± the voltage of 16.5V, be that there is single electricity of filter function in high input impedance and sheet
Source, therefore need not additional bipolar power supply and drives operational amplifier.
The as it is shown on figure 3, during energising of light intensity plate, have dark current and noise etc. to disturb signal in circuit, if the environment of test
Not being completely black dark condition, the external world also there will be interference signal, and interference signal is filtered, and needs to carry out including dark current and making an uproar
The background detection of sound；The condition of background detection should keep consistent with the condition of conventional sense, but light source should be at closed mode, will
The background signal read preserves to configuration file；The signal subtracting background signal that conventionally test reads obtains the light intensity of light source
Signal, the light intensity signal at this moment obtained is relative value, there is certain functional relationship with actual light intensity values, it is therefore desirable to by light
The data of strong plate measurement standard lamp, then mate with the truthful data of standard lamp, calculate light intensity calibration coefficient, utilize light intensity
Calibration coefficient demarcates the light intensity value of light source to be measured.
