Description
Technical field
The utility model belongs to a kind of atmospheric environment detecting instrument, is specifically related to a kind of portable dust detector.
Background technology
In dry clean air, the composition of trace gas is inappreciable.But in the air of certain limit, there is the micro substance originally do not had, its quantity and duration, all likely people, animal, plant and article, material have been had a negative impact and endangered.When in air, the concentration of polluter reaches detrimental extent, so that destroy the condition of the ecosystem and mankind's normal existence and development, people or thing are worked the mischief.
In order to reduce the harm of dust to human or animal, except country and society will strengthen except environment management, the protection of individual is also very important, therefore, need a kind of dust investigating, atmospheric dust reach be detrimental to health time, remind people carry out dust protection.
Utility model content
The purpose of this utility model is to provide a kind of portable dust detector, accurately can detect the dust in air, reach at atmospheric dust be detrimental to health time, remind people carry out dust protection.
For achieving the above object, the technical scheme that an embodiment of the present utility model is taked is:
Comprise detector housing, microprocessor is provided with in detector housing, microprocessor connects 40 millimeters of filter membrane online acquisition devices, storer, replaceable particle cutter, constant-current controller, dust concentration testing circuit, under-voltage protecting circuit and printer and computer output interface RS232, and 40 millimeters of filter membrane online acquisition devices connect high-performance aspiration pump; Detector housing front panel is provided with LCDs, sound ring alarm, alarm lamp, menu button and four select buttons, and LCDs, sound ring alarm, alarm lamp, menu button are all connected with microprocessor with select button.
Preferably, detector housing front panel is also provided with the not enough alarm lamp of electricity.
The beneficial effect that this portable dust detector produces is: accurately can detect the dust in air, reach at atmospheric dust be detrimental to health time, remind people to carry out dust protection.
Accompanying drawing explanation
Fig. 1 is the housing inner structure schematic diagram of an embodiment of a kind of portable dust detector of the present utility model.
Fig. 2 is the housing front-panel structure schematic diagram of an embodiment of a kind of portable dust detector of the present utility model.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, 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 a kind of portable dust detector of the present utility model.In the present embodiment, portable dust detector comprises detector housing 1, be provided with microprocessor 4 in detector housing 1, microprocessor 4 connects 40 millimeters of filter membrane online acquisition devices 3, storer 5, replaceable particle cutter 6, constant-current controller 7, dust concentration testing circuit 8, under-voltage protecting circuit 9 and printer and computer output interface RS232, while can be implemented in continuously monitoring bug dust concentration, can collecting granules matter sample, its composition is analyzed, and obtains mass concentration at short notice, and realize PM2.5, PM.5, PM10, TSP many kinds of cutter compatibilities, 40 millimeters of filter membrane online acquisition devices 3 connect high-performance aspiration pump 2, can be applicable to the detection of various environment, and result can print or output on computing machine and carry out off-line analysis by printer and computer output interface RS232, detector housing 1 front panel is provided with LCDs 10, sound ring alarm 11, alarm lamp 12, menu button 14 and four select buttons 13, LCDs 10, sound ring alarm 11, alarm lamp 12, menu button 14 is all connected with microprocessor with select button 13, LCDs 10 can read testing result intuitively, sound ring alarm 11 and alarm lamp 12 can be reported to the police in the mode of acousto-optic when the concentration of atmospheric dust exceedes the threshold value of setting, menu button 14 arranges menu for recalling, can the setting measurement time, unused time, preheating time, sampling number, dust concentration exceeds standard alarm threshold value, concentration max-thresholds and minute etc., can be set by four select buttons 13.
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 15 of electricity, reminds and changes power supply in time when electricity is not enough or charges to power supply.
Above-mentioned embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
