Description
Technical Field
The invention relates to the technical field of environment detection, in particular to environment detection equipment for a micro-environment allocation system and a detection method thereof.
Background
Microenvironment generally refers to a relatively small range of environments having more localized, specific features than an overall environment. For example, in the research of plant growth, a simulated microenvironment needs to be established for plant growth, and in order to ensure effective plant growth, a blending system needs to be set to continuously adjust environmental parameters so as to control various environmental parameters in the microenvironment, such as temperature, humidity, air particulate matter concentration, illumination intensity, oxygen concentration, carbon dioxide concentration and the like.
When plants grow, if more particles in the environment are attached to the plant leaves, pores on the leaves can be blocked, transpiration is reduced, photosynthesis is reduced, and in order to further study the influence of the particles in the air on the plant growth, the concentration of the particles in the air in the microenvironment needs to be adjusted, so that in the microenvironment allocation system, a dust sensor (also called a dust sensor) is needed, and the dust concentration in the surrounding air can be detected.
The working principle of the dust sensor is developed according to the scattering principle of light, and particles and molecules can generate scattering phenomenon of light under the irradiation of light, and at the same time, the dust sensor also absorbs part of energy of the irradiated light. When a beam of parallel monochromatic light is incident on the field of the particles to be measured, the light intensity is attenuated under the influence of scattering and absorption around the particles. Thus, the relative attenuation rate of the incident light passing through the concentration field to be measured can be obtained. The relative attenuation rate can reflect the relative concentration of dust in the field to be measured basically linearly. The intensity of the light is in direct proportion to the intensity of the electric signal subjected to photoelectric conversion, and the relative attenuation rate can be obtained by measuring the electric signal, so that the concentration of dust in a field to be measured can be measured.
For small ecological environments with more plants, the number of plants in the simulated microenvironment is correspondingly increased, and when moss exists in the microenvironment, plants requiring higher humidity from tropical rain forests or humid areas (such as ferns, orchids, scindapsus aureus and the like) belong to the category, effective control of the air humidity in the microenvironment is required to ensure higher humidity in the microenvironment.

With the long-term use of the apparatus, the condensed water on the inner wall of the condensation wall 21 is more and more concentrated, and therefore, referring to fig. 4 and 8 of the specification, the bottom of the inner wall of the pretreatment cylinder 2 is provided with a water collecting tank 24, the pretreatment cylinder 2 is provided with a discharge hole at a position corresponding to the water collecting tank 24, a one-way discharge pipe 25 is installed in the discharge hole, and a one-way valve structure for one-way discharging the accumulated water in the water collecting tank 24 is provided in the one-way discharge pipe 25, thereby isolating the outside air from directly entering the pretreatment cylinder 2 from the one-way discharge pipe 25.
It should be noted that, instead of the unidirectional discharge pipe 25, a switchable discharge pipe may be used, and the discharge pipe may be opened to perform concentrated discharge when the apparatus is not in use.
In the above embodiment, if the dust particles are more and the particle size is smaller, during actual detection, some dust particles adhere to the dust filter tube 32 and cannot enter the detection channel 11, so as to affect the detection accuracy, so this embodiment also provides a technical scheme, specifically, referring to fig. 3, 4, 9 and 10 of the specification, an elastic frame 331 is fixedly installed in the top end of the fixing frame 33, a rotation driver 6 is fixedly installed in the top end of the gas adding tube 5, the elastic frame 331 is fixedly installed on the output shaft of the rotation driver 6, and the rotation driver 6 is used for driving the fixing frame 33 and the dust filter tube 32 to rotate.
It should be noted that, during actual use, the dust filter tube 32 can be driven to rotate continuously, so as to avoid the dust filter tube 32 being static, and thus the dust particles can move relative to the dust filter tube 32 all the time, and the dust particles are prevented from adhering to the dust filter tube 32.
Further, the elastic protrusions 333 are fixedly mounted on the circumferential side wall of the top of the fixing frame 33 and the position of the detector housing 1 corresponding to the circumferential side wall of the top of the fixing frame 33, and when the fixing frame 33 rotates, the elastic protrusions 333 on the fixing frame 33 and the elastic protrusions 333 on the detector housing 1 touch each other, so that the dust filter tube 32 continuously vibrates, and the dust particle adhesion preventing capability is further improved.
Further, referring to fig. 4 and 6 of the specification, a plurality of sets of cyclone blades 332 are fixedly mounted on the inner wall of the bottom of the fixing frame 33, and the cyclone blades 332 drive the air flow inside the dust filter tube 32 to rotate when the fixing frame 33 rotates, and the rotating air flow has centrifugal force, so that the speed of the gaseous water passing through the dust filter tube 32 can be improved.
Referring to fig. 11 of the specification, an environment detection method for a micro-environment deployment system includes the following steps:
step one, starting a heater 4 in a pretreatment cylinder 2 for preheating;
step two, starting a first air extraction device 12 to enable the detection channel 11 to start air extraction, enabling external air to enter the pretreatment cylinder 2, heating by the heater 4, and enabling moisture on the surfaces of dust particles to evaporate into gaseous water;
step three, separating the gaseous water in the air from dust particles through the separation structure 3, so that the dust particles enter the detection channel 11 from the dust channel and pass through a field to be detected of the dust detection sensor 13 for detection;
and step four, the dust detection sensor 13 feeds back detection information to the micro-environment allocation system, and the micro-environment allocation system adjusts the concentration of dust particles.
It should be noted that, the concentration adjustment of the dust particles can be realized together through the dust releaser and the ventilation system, when the concentration of the dust particles is increased, the ventilation system can be accelerated to replace and purify the air in the microenvironment, and when the concentration of the dust is low, the dust releaser can be utilized to release the dust into the microenvironment.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
