Description
Technical field
This utility model belongs to environmental monitoring technology field, is specifically related to a kind of Intelligent environment monitor.
Background technology
Along with economy particularly industrial expansion, the environment that we depend on for existence receives serious pollution, to people group
Many physical and mental healths adversely affect.In order to reverse this unfavorable situation, country strengthens the dynamics of environmental improvement year by year.Environment
Monitoring is foundation and the premise of environmental improvement, therefore, and the market demand cumulative year after year to enviromental monitoring equipment in recent years.
For accurate measurements environmental aspect, administer for implementation environment and scientific basis is provided, be necessary for requiring that environmental monitoring sets
Standby detection project is extensive as far as possible, covers the main monitoring project affecting environmental quality, and testing result to have height
Accuracy.But, enviromental monitoring equipment in the market, it is difficult to meet above-mentioned requirements.It is primarily present problems with:
One is that quality is uneven.Quality includes content of both accuracy of detection and accuracy in detection, accuracy of detection master
Depend on certainty of measurement and the operational precision of computing chip of selected sensor, most of air inspection the most on the market
What measurement equipment used is all cheap sensor, and this accuracy that directly results in testing result and degree of accuracy can not reach to want
Ask.Accuracy in detection, needs the test environment of standard and calibration facility to ensure, most of air detection the most on the market set
It is standby all without the professional equipment demarcation of national standards laboratory, so accuracy of detection is difficult to be guaranteed.
Two is that detection project varies.Dragons and fishes jumbled together for air detection equipment the most on the market, and the project of detection is also
Varying, most detection equipment are all with temperature, humidity, TVOC, formaldehyde as fixed Combination or with PM2.5, temperature
Degree, humidity be fixed Combination form occur, but in the middle of our daily life we need be concerned about ambient parameter,
Never only these, also should include fuel gas, carbon monoxide, oxygen, electromagnetic radiation, these projects of ionizing radiation, Qi Zhongke
Combustion gas body is related to our household safe problem, and the concentration of fuel gas may set off an explosion after reaching certain value.One oxidation
Carbon is more known as the killer of stealth, and after indoor carbon monoxide reaches finite concentration, indoor occupant can produce moderate phenomenon
Even threat to life.The significance level of oxygen is self-evident, but the health that too high oxygen level can make people equally produces
Discomfort, so needing monitoring in real time.Electromagnetic radiation and ionizing radiation are that everybody compares two projects of care, electromagnetism spoke in recent years
Penetrating is a kind of compound electromagnetic wave, transmits energy over time with orthogonal electric field and magnetic field.Human life is lived
Moving and comprise a series of bioelectric, these bio electricities are very sensitive to the electromagnetic wave of environment, and therefore, electromagnetic radiation can be right
Human body impacts and damages.Under electric radiation effect, the extent of reaction of body depends on the kind of ionizing radiation, dosage, photograph
Penetrate the sensitivity of condition and body.Ionizing radiation can cause radiation sickness, and it is the systemic reaction of body, nearly all organ,
All there is pathological change in system, but wherein change with nervous system, hemopoietic organ and digestive system is the most obvious.Ionizing radiation
Damage to body can be divided into acute radiation injury and chronic radioactive damage.The irradiation of doses is accepted in short time, can
Cause the acute injury of body, see nuclear accident and radiation therapy patient at ordinary times.And dispersion accepts doses in the long period
Irradiation, chronic radioactive can be caused to damage, such as skin injury, hematopoietic disorders, leukopenia, impaired fertility etc..It addition,
Radiation can also carcinogenic with cause death and the deformity of fetus.So through careful analysis and research, this utility model will close
It is in the middle of 10 parameter integrations to equipment of our daily life, to guarantee to meet the need of people's daily life
Ask.
