Technical field
The present invention relates to a kind of formaldehyde examination system, and in particular to the formaldehyde that avoid air velocity influences on test result is surveyed
Test system.
Background technology
Combine what is promulgated by the Ministry of Public Health, State Environmental Protection Administration and State Administration for Quality Supervision and Inspection and Quarantine《GB/T18883-
2002 Indoor Air Quality standards》The basic standard of substantially one healthy residential environment, to building developer, finishing business,
Furniture dealer does not obligate power.Promulgated by the Ministry of Construction, State Administration for Quality Supervision and Inspection and Quarantine's joint《Civil buildings work
Journey indoor environmental pollution controls specification》GB50325-2001 (2006 editions) is then in the control of civil building engineering indoor environmental pollution
Aspect, has the testing conditions of the testing conditions ratio of enforceable acceptance of work standard seriously loose builder and finishing business,
Although the former pollutant concentration limit value is slightly less than the latter, the condition closed the doors and windows before detection only has 1 hour, and the latter is 12
Hour.Therefore, the end user in vast house is pointed out, by the civil building engineering and interior decoration engineering of standard final acceptance of construction
House, be not equal to the adequate condition for reaching people's health in residential environment.If introducing furniture in house, no matter the new home or old room,
IAQ is likely to further decline, the IAQ detection carried out of considering for life and health, is only measurement
Whether house meets the fundamental basis of healthy residential environment standard.
And it is reported that, there are currently no any one detecting system can ensure to flow through detection liquid surface within the unit interval
Air mass flow, therefore, testing result are influenceed greatly by factors such as temperature, humidity and air velocitys, so as to cause larger error.
The content of the invention
The technical problems to be solved by the invention are to there are currently no any one detecting system to ensure in the unit interval
The air mass flow on detection liquid surface is inside flowed through, therefore, testing result is influenceed greatly by factors such as temperature, humidity and air velocitys,
So as to cause larger error, it is therefore intended that offer avoids the formaldehyde test system that air velocity influences on test result, solve
There are currently no any one detecting system can ensure to flow through the air mass flow on detection liquid surface, therefore, inspection within the unit interval
Survey result is influenceed greatly by factors such as temperature, humidity and air velocitys, so that the problem of causing larger error.
The present invention is achieved through the following technical solutions：
The formaldehyde test system for avoiding air velocity from influenceing test result, including formaldehyde examination device, including processor
With the flow sensor, timer and speed regulator connected on processor, blower fan is also associated with the speed regulator；
Processor：The control signal of signal input is received, the time parameter extracted in control signal is sent to timer；Connect
A control signal for the collection of letters number input, receives the gas flow rate that flow sensor is sent, and control parameter is generated after processing and is sent to tune
Fast device；
Flow sensor：The gas flow rate in formaldehyde examination device is detected, gas flow rate is sent to processor；
Signal input module：The extraneous control signal sent is received, processor is sent control signals to；
Timer：The time parameter that reception processing device is sent, according to the start and stop of time parameter control system；
Speed regulator：The control parameter that reception processing device is sent, is controlled according to control parameter to blower fan；
Blower fan：The control for receiving speed regulator is operated.The side that this programme passes through the setting blower fan on formaldehyde examination device
The flow velocity of air in formula control detection means, reduction testing result is influenceed by the factor of temperature, humidity and air velocity etc..Processing
Device is controlled using feedback control to speed regulator, and the control parameter of input is the control signal that signal input module is inputted, instead
Feedforward parameter is the gas flow rate in the detection formaldehyde examination device that flow sensor is gathered, meanwhile, controlled by timer whole
The working time of system.
Database is also associated with the processor.Database is supported for the data that processor provides big data.
Reminding module is also associated with the processor.Because the testing time also has a certain impact to test result, lead to
The mode that reminding module is set on a processor is crossed, operating personnel's collecting test result is reminded in time after the completion of test.
The test paper or reagent of the positive PARA FORMALDEHYDE PRILLS(91,95) detection means of wind direction of the blower fan, the flow sensor are located at formaldehyde examination
On the test paper of device or reagent ullage.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention avoids the formaldehyde test system that air velocity influences on test result, and test paper is controlled by adjustable speed fan
The flow velocity of superficial air, testing result reliability is high；
2nd, the present invention avoids the formaldehyde test system that air velocity influences on test result, with independent reminding module,
The timely acquisition testing result of operating personnel is pointed out upon completion of the assays.
