Abstract
An ultraviolet ray detector comprises an optical filter, an ultraviolet ray sensor, a signal amplification circuit, a photosensitive diode, a singlechip and an LED display. The optical filter is connected with the ultraviolet ray sensor; the photosensitive diode is connected with the ultraviolet ray sensor in parallel and connected with the signal amplification circuit in series; and a signal amplified through the signal amplification circuit and processed through the singlechip is output to the LED display. With the above structure, the optical filter filters out light source except the ultraviolet ray, an ultraviolet signal is detected by the ultraviolet ray sensor, amplified through the signal amplification circuit and sent to the singlechip for analysis and processing, and processed data is transmitted to the LED display for display, therefore, the value of the ultraviolet ray intensity can be seen, thereby achieving the purpose of conveniently and quickly detecting the intensity of the ultraviolet radiation of indoor lighting lamps.
Description
Technical field
The present invention relates to a kind of detector, particularly a kind of ultraviolet detector.
Background technology
The ultraviolet strong and weak data of the ultraviolet apparatus measures of existing measurement, out of true, and do not have can be at the indoor instrument that carries out the UV detection of lighting.
Summary of the invention
Purpose of the present invention is exactly that a kind of ultraviolet detector that can carry out ultraviolet security measurement to indoor illumination light fitting will be provided,
The object of the present invention is achieved like this: a kind of ultraviolet detector, comprise optical filter, UV sensor, signal amplification circuit, photodiode, single-chip microcomputer and light-emitting diode display, optical filter links to each other with UV sensor, connect with signal amplification circuit after photodiode and the UV sensor parallel connection, by the signal amplification circuit amplifying signal after single-chip microcomputer is handled to light-emitting diode display.
Owing to adopt said structure, by optical filter light source beyond the ultraviolet ray is filtered, the detected UV signal of Ultraviolet sensor, amplify through signal amplification circuit, deliver to single-chip microcomputer and carry out analyzing and processing, the data of handling well are passed to light-emitting diode display show, just can see the numerical value of uitraviolet intensity, reach the purpose that detects indoor illumination light fitting ultraviolet radiation power quickly and easily.
Description of drawings
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present invention.
Fig. 1 double as Figure of abstract.
Among the figure: 1, UV sensor, 2, signal amplification circuit, 3, photodiode, 4, single-chip microcomputer, 5, light-emitting diode display.
Embodiment
As shown in Figure 1, a kind of ultraviolet detector, comprise optical filter, UV sensor 1, signal amplification circuit 2, photodiode 3, single-chip microcomputer 4 and light-emitting diode display 5, optical filter links to each other with UV sensor 1, connect with signal amplification circuit 2 in photodiode 3 and UV sensor 1 back in parallel, by signal amplification circuit 2 amplifying signals after single-chip microcomputer 4 processing to light-emitting diode display 5.
Detect principle: houselights is by filter glass, filters the light source beyond the ultraviolet ray, and what shine Ultraviolet sensor 1 has only ultraviolet light source (100-400nm).When ultraviolet light source, the silicon photocell two ends in the Ultraviolet sensor 1 will produce electric current.
Ultraviolet light source is superpower, the electric current at the two ends of silicon photocell is just big more in the Ultraviolet sensor 1, the voltage that amplifies output through operational amplifier (HA17324) direct current in the signal amplification circuit 2 is just high more, be connected on the photodiode 3 at operational amplifier (HA17324) two ends, outside receiving during light source, operational amplifier (HA17324) is produced a negative-feedback signal, and outer light source is superpower, and negative feedback is just strong more.Make the ultraviolet source signal of output more stable.
Signal voltage after the amplification carries out AD conversion (simulating signal changes into digital signal) analyzing and processing delivering to single-chip microcomputer, the data of handling well is passed to light-emitting diode display 5 show that we just can see the numerical value of uitraviolet intensity.
During use, connect down power knob, the display screen of display 5 shows 888, and self check is aimed at ultraviolet light source dodging 888 with the present invention, and display screen shows uitraviolet intensity automatically.From 0-100, uitraviolet intensity is big more, show that numerical value is big more, surpasses 100, only shows 100.
