Description

With dust detection and the bus platform of air-cleaning function

Technical field

This utility model relates to a kind of with dust detection and the bus platform of air-cleaning function, at bus platform column Detection module and cleaning module are inside installed, by detection module optics dust measuring, detect dust in air and PM2.5 granule, as Exceed setting numerical value, i.e. start cleaning module, the dust removed near bus platform in air and PM2.5 granule, and have and kill Bacterium function, it is achieved local air dedusting and purification.

Background technology

Near Present Domestic bus platform, air quality causes anxiety, and dust in air content and PM2.5 index remain high, existing Having bus platform, have no and can realize dust detection and the design of air cleaning simultaneously, this patent uses optical detection dust and quiet Electrostatic precipitation technology, the dust that can detect and remove near bus platform in air and PM2.5 granule, kill antibacterial simultaneously, it is achieved Local air dedusting and purification.

Utility model content

Its purpose of this utility model is that provides the detection of a kind of band dust and the bus platform of air-cleaning function；Our station The design of platform includes two modules: wherein detection module includes laser instrument, lens, diode, dust sensor and single-chip microcomputer system System；Cleaning module includes two-stage filter screen, inlet and outlet fan, discharge lines, collecting plate, positive high voltage DC source and control circuit； Compared with existing bus platform, our station independence for Taiwan has and integrates dust detection and the function of electrostatic precipitation module, can detect also the most clearly Except the dust in air near bus platform and PM2.5 granule, kill antibacterial, it is achieved local air dedusting and purification simultaneously, with Time to have design simple, with low cost, the feature of easy maintenance.

For realizing above-mentioned target, this patent first passes through the laser instrument in detection module as light source, sends light beam through thoroughly Mirror is received by diode, produces the electric impulse signal that is in proportion with particulate in air, photodiode as receptor, I.e. can detect that the numerical value of dust in air granule according to the change of receptor light quantity, the information of reception through Single Chip Microcomputer (SCM) system point Analysis, as the koniology collected or PM2.5 numerical value exceed setting value, i.e. starts cleaning module by single-chip microcomputer；Purifying mould In block, positive high voltage DC source generates high voltage direct current, is loaded in discharge lines by positive pole, and negative pole is loaded on collecting plate, shape Becoming corona discharge, air inlet fan is by air inspiration column to be clean, through the two-stage strainer filtering before passing through fan and after fan After, through discharge lines, make dust and PM2.5 granule positively charged, then make to be adsorbed onto on collecting plate through collecting plate, last air-out One's intention as revealed in what one says fan discharges column by purifying air, and detection module certain interval of time detects again, such as the air ash collected Dirt or PM2.5 numerical value, less than setting value, i.e. close cleaning module by single-chip microcomputer.

Compared with prior art this utility model has the following advantages.

Patent No. ZL201520114221.1 that existing Patents only completes in person, patent entitled " band dedusting and The bus platform of air-cleaning function ", only air-cleaning function, it is impossible to detection dust in air granule and PM2.5 number automatically Value, needs hand switch air-cleaning function；This patent innovates detection dust numerical value automatically on my existing Research foundation, and Numerical value can be analyzed by single-chip microcomputer, automatically turn on air-cleaning function, effectively saved manpower and resource, real with low cost Air monitering near bus platform, dedusting, purification and sterilizing function are showed.

Accompanying drawing explanation

1 pair of this utility model is further described below in conjunction with the accompanying drawings.

Accompanying drawing 1 is bus platform dust detection module and electrostatic precipitation module functional-block diagram.

Detailed description of the invention

This patent is on the basis of existing bus platform, in the one side of bus platform column, adds detection module with clean Change module.

The detection PM2.5 Fundamentals of Sensors that this patent uses are to use optics dust measuring principle, use laser PM2.5 sensing Device；Laser instrument, as light source, sends light beam and is received by diode through lens, and generation and particulate in air are in proportion Electric impulse signal, diode uses photodiode, and photodiode is as receptor, it is possible to produce according to the change of intensity of illumination Raw phase induced current, i.e. can detect that the numerical value of dust in air granule, and the information of reception is through the analysis of Single Chip Microcomputer (SCM) system, as adopted Collect to air PM2.5 numerical value exceed setting value, i.e. start cleaning module by single-chip microcomputer.

In cleaning module, described discharge lines connects the positive pole of positive high voltage DC source, and described collecting plate is just connecting The negative pole of high-voltage DC power supply, is shown in accompanying drawing, produces therebetween corona discharge so that in air, fine particle lotus is just after energising Electricity, is adsorbed by collecting plate, uses positive high voltage electric discharge to be effectively reduced ozone and produces, it is to avoid air secondary is polluted.

Described two-stage filter screen is the one-level filter screen outside air inlet fan and the secondary screen in column respectively, sees accompanying drawing, For crossing bulky grain object in air filtering.

Described control circuit connects inlet and outlet fan and positive high voltage DC source, for providing the control of necessity, sees Accompanying drawing.

The work process of this patent detection dust and purification air is as follows.

1, laser instrument sends light beam and is received by light emitting diode through lens, produces and is in proportion with particulate in air Electric impulse signal.

2, photodiode is as receptor, produces phase induced current according to the change of intensity of illumination, detects that air is mellow lime The numerical value of dirt granule.

3, the information received is through the analysis of Single Chip Microcomputer (SCM) system, sets as the koniology collected or PM2.5 numerical value exceed Definite value, i.e. starts cleaning module by single-chip microcomputer.

4, air inlet starting fan, by air to be clean in one-level filter screen sucks column.

5, air outlet starting fan, in column, negative pressure reduces so that band purifies upward motion of air.

6, band purification air is after two machine filter nets, then through discharge lines, band purifies the fine particle lotus positive electricity in air, Through collecting plate, because of electrostatic, there is a natural attraction between the sexes, can be adsorbed on collecting plate, has purified air and has continued up, air outlet has discharged Column.

7, detection module certain interval of time detects again, as the koniology collected or PM2.5 numerical value are less than Setting value, i.e. closes cleaning module by single-chip microcomputer.

The content not being described in detail in this specification belongs to the prior art well known to professional and technical personnel in the field.
