Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.It is understood that herein Described specific embodiment is used only for explaining the utility model, rather than the restriction to the utility model.It further needs exist for It is bright, part relevant to the utility model is illustrated only for ease of description, in attached drawing rather than entire infrastructure.
Embodiment
Fig. 1 is a kind of structural schematic diagram of ventilation cleaning control system provided by the embodiment of the utility model, be can be used for pair Air in the public places such as public lavatory is aerated bactericidal purifying.As shown in Figure 1, the ventilation cleaning control system, including：Always wave Hair property organic compound (Total Volatile Organic Compounds, TVOC) sensor 110, CO2Sensor 120, Purge module 130 and controller 140, wherein
TVOC sensor 110, for detecting the concentration scale of the total volatile organic compounds gas in public lavatory environment；
CO2Sensor 120, for detecting the CO in public lavatory environment2Concentration；
Purge module 130 is connected with controller 140, under the control of the controller 140 to gas in public lavatory environment into Row ventilation bactericidal purifying；
Controller 140, respectively with TVOC sensor 110 and CO2Sensor 120 is connected, for according to TVOC sensor 110 And CO2The testing result control purge module 130 of sensor 120 opens work and/or adjusts the Working mould of purge module 130 Formula.
TVOC sensor 110 is a kind of for detecting the sensor of TVOC gas concentration level, and output signal can be Be used to indicate TVOC gas concentration is high, in TVOC gas concentration, TVOC gas concentration is low or the level signal of pure air. TVOC is to influence more serious one kind in three kinds of influence indoor air quality pollutants, mainly includes benzene homologues, organic chloride Object, freon series, organic ketone, amine, alcohol, ether, ester, acid and petroleum hydrocarbon compound etc., can deposit in gaseous form at normal temperature It is in air, its toxicity, irritation, carcinogenicity and special odor profiles will affect skin and mucous membrane of people etc., and then right Human body generates acute lesion.Indoor TVOC concentration is usually in 0.2mg/m3To 2mg/m3Between, when indoor TVOC concentration exists 0.16mg/m3~0.3mg/m3When, it is substantially harmless to human health.So TVOC sensor 110 can detect TVOC gas After bulk concentration numerical value, corresponding TVOC gas concentration level is exported with the signal of level signal.
TVOC gas concentration level in 110 real-time detection public lavatory of TVOC sensor, and will be with TVOC gas concentration level Corresponding level signal is sent to controller 140 as testing result, so that controller 140 knows the TVOC gas in public lavatory at this time Bulk concentration grade.
Due to CO in room air2The impression of concentration and human body is closely related, and worth people enhance your vigilance.In room air CO2Concentration belongs to clean air in 700ppm or less, and people can feel very comfortable；When concentration is in 700ppm to 1000ppm Also it can be said to be normal, belong to normal air, but some can have not so good feeling than more sensitive people；Work as CO2Concentration is super 1000ppm, but in 1500ppm range, air is in critical stage, the feeling that many people may experience discomfort；Work as CO2It is dense When degree reaches 1500ppm to 2000ppm, air belongs to slight pollution, and then belonging to more than 2000ppm seriously polluted, if human body The excessively high CO of long-term inhaled concentration2When, it will cause biological clock disorder, CO2Concentration can inhibit respiratory center when high, concentration is special To respiratory center, there are also paralysis effects when not high；Work as CO2When concentration is in 3000ppm between 4000ppm, it will lead to people and exhale It inhales and deepens, the shapes such as headache, tinnitus, blood pressure increase occur.So CO in air2Concentration is also to measure whether room air cleans One of standard.
Therefore, CO is set in ventilation cleaning control system2Sensor 120 detects the CO in public lavatory environment2Concentration etc. Grade, CO2The output signal of sensor 120, which can be, is used to indicate CO2Concentration height, CO2In concentration, CO2Concentration is low or clean sky The level signal of gas.CO2CO in 120 real-time detection public lavatory of sensor2Concentration and then determining CO2Concentration scale, and will be with CO2 The corresponding level signal of concentration scale is sent to controller 140 as testing result, so that controller 140 is known in public lavatory at this time CO2Concentration scale.
Controller 140 is by CO2A kind of supplement of the testing result of sensor 120 as 110 testing result of TVOC sensor, In conjunction with 110 testing result of TVOC sensor and CO2The testing result of sensor 120 determines the air pollution of environment in current public lavatory Grade, and then purge module 130 is controlled according to determining air pollution grade, so that purge module 130 is executed to public affairs Air is aerated the operation of bactericidal purifying in lavatory.For example, in TVOC sensor 110 and CO2The testing result of sensor 120 is equal When for pure air, controller 140 controls purge module 130 and stops ventilation bactericidal purifying operation, to reduce power consumption；It is passed in TVOC Sensor 110 and CO2In the testing result of sensor 120 it is any be non-pure air when, controller 140 control purge module 130 Start bactericidal purifying operation of divulging information；In TVOC sensor 110 and CO2When any high for concentration in the testing result of sensor 120, Controller 140 controls purge module 130 and adjusts operating mode, for example control purge module 130 improves working efficiency, increases air quantity Etc..
