Description
Technical field
The utility model belongs to a kind of atmospheric environment detecting instrument, is specifically related to a kind of laser dust detector.
Background technology
In dry clean atmosphere, the composition of trace gas is inappreciable.But in the atmosphere of certain limit, occurred the micro substance that originally do not have, its quantity and duration, all likely to people, animal, plant and article, material production adverse effect and harm.In atmosphere, the concentration of polluter reaches harmful degree, so that destroy the condition of the ecosystem and mankind's normal existence and development, people or thing is worked the mischief.
In order to reduce the harm of dust to human or animal, except national and society will strengthen environment management, individual's protection is also very important, therefore, need a kind of dust investigating, at atmospheric dust, reach while being detrimental to health, remind people to carry out dust protection.
Utility model content
The purpose of this utility model is to provide a kind of laser dust detector, can the dust in atmosphere accurately be detected, and is reaching while being detrimental to health at atmospheric dust, reminds people to carry out dust protection.
For achieving the above object, the technical scheme that an embodiment of the present utility model takes is:
Comprise detector housing, in detector housing, be provided with microprocessor, microprocessor connects 40 millimeters of filter membrane online acquisition devices, storer, replaceable particle cutter, laser generator, ac-dc dual power supply, dust concentration testing circuit, under-voltage protecting circuit, self-calibration system and printer computer output interface RS232; In detector housing, being also provided with optical standard falls apart and protects air curtain; Detector housing front panel is provided with LCDs, sound ring alarm, alarm lamp, menu button and four selection buttons, and LCDs, sound ring alarm, alarm lamp, menu button are all connected with described microprocessor with selection button.
Preferably, detector housing front panel is also provided with the not enough alarm lamp of electric weight.
The beneficial effect that this laser dust detector produces is:
1, can the dust in atmosphere accurately be detected, at atmospheric dust, reaching while being detrimental to health, remind people to carry out dust protection.
2, detector adopts LASER Light Source, and mass concentration conversion coefficient is not subject to the impact of particle color.
3, there is in-built optical standard and fall apart, guarantee instrument high stability.
4, there is special protection air curtain, avoided the pollution of dust to instrument core component-optical system, guarantee instrument high reliability.
5, instrument can be set the dust concentration alarm threshold value that exceeds standard, automatic sound-light alarm during dust exceeding, or transfer signals to control center and monitor.
6, design analog output interface circuit, when air purifier is evaluated, can draw out purification efficiency appraisal curve.
Accompanying drawing explanation
Fig. 1 is the housing inner structure schematic diagram of an embodiment of laser dust detector of the present utility model.
Fig. 2 is the housing front-panel structure schematic diagram of an embodiment of laser dust detector of the present utility model.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1, Fig. 2, Fig. 1, Figure 2 shows that the structural representation of an embodiment of laser dust detector of the present utility model.In the present embodiment, laser dust detector comprises detector housing 1, in detector housing 1, be provided with microprocessor 5, microprocessor connects 40 millimeters of filter membrane online acquisition devices 2, storer 3, replaceable particle cutter 4, laser generator 6, ac-dc dual power supply 7, dust concentration testing circuit 8, under-voltage protecting circuit 9, self-calibration system 10 and printer computer output interface RS232; Detector adopts LASER Light Source, and mass concentration conversion coefficient is not subject to the impact of particle color; Can realize in continuous monitoring bug dust concentration, can collecting granules matter sample, its composition is analyzed, and obtained mass concentration at short notice, and realize PM2.5, PM.5, PM10, many kinds of cutter compatibilities of TSP; Printer and computer output interface RS232 can print result or output to and on computing machine, carry out off-line analysis; In detector housing, be also provided with optical standard and fall apart 11 and protection air curtain 12, optical standard falls apart and 11 guarantees instrument high stability, and protection air curtain 12 has been avoided the pollution of dust to instrument core component-optical system, guarantees instrument high reliability.Detector housing 1 front panel is provided with LCDs 13, sound ring alarm 14, alarm lamp 15, menu button 17 and four selection buttons 16, and LCDs 13, sound ring alarm 14, alarm lamp 15, menu button 17 and selection button 16 are all connected with described microprocessor 5.LCDs 13 can read testing result intuitively, when can surpassing the threshold value of setting in the concentration of atmospheric dust, sound ring alarm 14 and alarm lamp 15 report to the police in the mode of acousto-optic, menu button 17 arranges menu for recalling, can the setting measurement time, exceed standard alarm threshold value, concentration max-thresholds and minute etc. of unused time, preheating time, sampling number, dust concentration, can set by four selection buttons 16.
With reference to figure 1, Fig. 2, in an embodiment of the present utility model, detector housing 1 front panel is also provided with the not enough alarm lamp 18 of electric weight, reminds and when electric weight is not enough, changes in time power supply or power supply is charged.
Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model is limited; in the protection domain of spirit of the present utility model and claim, any modification and change that the utility model is made, all fall into protection domain of the present utility model.
