Description
Technical field
The present invention relates to a kind of four-sensor formula illuminometer, belong to road lighting luminance detection technical field.
Background technology
Existing illuminometer is the single-sensor illuminometer, is made up of single illuminance transducer, operational amplifier, A/D converter, single chip processing module, display module.At present, in the road lighting industry at home, all use single traditional sensor illuminometer, adopt the method for artificial point-to-point measurement to detect the data such as average illumination of street lamp illumination system.One of method of so-called artificial point-to-point measurement is about to measurement highway section between two lamp stands and is divided into several length and widths and is 1 meter equal-sized rectangular node, is located at grid element center to measurement point.Between each measurement point at a distance of 1 meter if adopt traditional single-sensor illuminometer measurements to have measured point count many (average illumination of the pavement of road between general two lamps need be measured about individual putting up to a hundred), data recording, shortcoming that the work of treatment amount is big, and the road that has been open to traffic carried out illumination photometry also have bigger traffic safety hidden danger.
Summary of the invention
The purpose of this invention is to provide a kind of four-sensor formula illuminometer, can be used for detection, the assessment of street lamp illumination system average illumination.
The objective of the invention is to realize like this: circuit is that 1 meter square frame is formed by illuminance transducer, operational amplifier, A/D converter, single chip processing module, display module and the length of side; Operational amplifier links to each other with A/D converter; A/D converter links to each other with single chip processing module; Single chip processing module links to each other with display module; It is characterized in that: two illuminance transducers link to each other with two operational amplifiers respectively, and it is on four angles of square frame of 1 meter that four illuminance transducers place the length of side respectively.Two illuminance transducers are the photodiode sensor, are the precision that guarantees measurement, its sensitivity, cosine response, spectral response, response linearity and consistent as far as possible to the parameters such as susceptibility of temperature; A/D converter adopts the chip of ADC0809 model; Single chip processing module is with the single-chip microcomputer of STC89C52 model; The length of side is that 1 meter square frame adopts transparent organic glass manufacturing.The single-chip microcomputer of the chip of ADC0809 model and STC89C52 model operating circuit commonly used is that those skilled in the art know.
Because adopt technique scheme, advantage and good effect that the present invention had are: have that detection efficiency height, measuring error are little, the workload of data recording and processing is little, traffic safety factor is high.Through site test and theoretical analysis; Adopt four-sensor formula illuminometer to measure, the illumination of four points of one-shot measurement, and get four mean value; Can work efficiency be improved about three times like this; Reduce the workload of number of times, data recording and the processing of measuring, shortened the time of measuring simultaneously, reduced the traffic hazard coefficient.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Figure of description is a circuit principle structure block diagram of the present invention.
