With the rapid development of China's economy, people's living standards have also improved rapidly. Therefore, cars are becoming more and more popular. With the popularity of cars, parking spaces on the ground have obviously been unable to accommodate, and underground garages have emerged. For example, major shopping malls, major office buildings, various high-rise communities, etc., crowded areas, the ground is not so large area can be used to build parking lots, only the development of underground garages. The underground garage does greatly alleviate the problem of parking difficulties, but it also brings other safety hazards. First of all, the underground garage is a relatively closed space, and the air circulation must be poor; then the vehicles are basically in and out of the underground garage. In the state of idling, the car exhaust discharged in this state will contain a lotCO。

AndCOIt is a kind of gas that is easy to be poisoned and poisoned in the underground garage. It is a product of incomplete combustion of carbon. When a person inhales carbon monoxide, it is absorbed into the blood by the lungs. Because carbon monoxide and hemoglobin affinity than oxygen210Times, which quickly formed carbon oxygen hemoglobin, hindered the ability of hemoglobin to transport oxygen, resulting in severe hypoxia, poisoning. According to the test: adults are allowed to beThe large concentration of carbon monoxide in the air is50ppm; reach200ppmWhen healthy adults2～3After hours, slight headache, fatigue; reach400ppmWhen healthy adults1～2forehead pain within hours,3Threat to life after hours;800ppmWhen healthy adults45Within minutes, dazzle, nausea, cramps,2Lose consciousness within hours,2～3Death within hours.

SinceCOIt is so harmful to human body that we have to find a way to solve it. General garage commonly used scheme is: online monitoringCOThe concentration. Then accordingCOConcentrated start-stop exhaust and air supply equipment (long-term start-up not only consumes large energy, but also easily overloads the equipment).AccordingCOtoxicity, it is generally recommended that the alarm value be set30ppmWhen the concentration value exceeds30ppmAt the same time, the automatic control system of the underground garage automatically prompts the alarm and starts the transmission in linkage./Exhaust fan, less30ppmAbout five minutes to stop delivery/Exhaust fan (for the consideration of frequent start-up of the equipment, the delay start-up and stop time of the equipment is adjustable) to ensure that the air quality in the underground garage area is within a safe range.

BecauseCOToo much harm to the human body, soCODetection is very important. I need a good one at this time.COsensors.Here, recommend one.COSensorTGS5141The sensor has the advantages of high sensitivity, long life and good long-term stability, and is very suitable for underground garages.COConcentration monitoring.
