Description
Technical field
The utility model belongs to the measurement mechanism field that environmental protection is used, and relates to a kind of portable full stream opacity smoke meter, is used for detecting the pick-up unit of the visible pollutant of motorcycle engine smoke evacuation.
Background technology
Along with people more and more pay attention to environmental requirement, to the detection of the visible pollutant of motorcycle emission also standard gradually, mostly checkout equipment in the past is the detection at automobile, to the detection of motorcycle emission still seldom, but the visible pollutant of motorcycle emission brings very big harm to our life, need detect observable refuses such as the blue smoke of motorcycle emission, white cigarette, mist of oils.Present detecting instrument, when carrying out surveying work in the open air, not free demonstration can bring great inconvenience on the instrument, and in use, owing to there is not the setting of license plate number, each vehicle does not have and measurement result is set up good corresponding relation, makes to seem very chaotic when rechecking, and the pick-up unit of therefore releasing visible pollutant in a suitable motorcycle smoke evacuation is very important.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of portable full stream opacity smoke meter is provided, the demonstration time and the storage cart trade mark, and tachometric survey is accurate, makes instrument miniaturization, and portability make the user to use more convenient.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of portable full stream opacity smoke meter that provides according to the utility model, the measuring unit and the control module that comprise split-type structural, measuring unit is made up of measuring chamber in casing and the cabinet and metering circuit, control module is made up of the control circuit in casing and the cabinet, described metering circuit is by singlechip CPU, A/D converter, the signals collecting amplifying circuit, photoelectric commutator, the light source generating means, power supply and oil temperature sensor are formed, photoelectric commutator and signals collecting amplifying circuit, A/D converter and singlechip CPU input sequence connect, and the photoelectricity generating means is connected with power supply; Described control circuit is made up of signals collecting amplifying circuit, microchip control circuit, auxiliary functional circuit, digitron display screen, button, clock chip, printer, the output terminal of signals collecting amplifying circuit, auxiliary functional circuit and button are connected the input end of microchip control circuit respectively, the output terminal of microchip control circuit connects digitron display screen, the microchip control circuit is exported signal, shows measurement data through button by digitron display screen.
Aforesaid measuring chamber inner light source generating means is installed in an end of flue, and optical sensor is installed in the other end of flue, and the flue front end leaves gas inlet and is connected with exhaust gas collector.
A measuring-signal interface socket is arranged on the casing of aforesaid measuring unit, be used to connect measuring unit and control module.
The utility model compared with prior art has significant advantage and beneficial effect.
The utility model is equipped with heating plate in measuring chamber, after start to the measuring chamber preheating, thermostatically-controlled equipment can be to the measuring chamber thermostatic control, avoid the influence of temperature change measuring accuracy, owing to increased clock chip, can be on liquid crystal display the demonstration time, user-friendly, with national each province, the car plate prefix of autonomous region and municipality directly under the Central Government is stored into, when detecting vehicle, just can directly call, the input license plate number gets final product, but printer changes the paper direct control in addition, take off roller bearing as long as open printer rear cover, change new printer paper and get final product, need not to open cabinet, more simple and fast.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
