Description

[0001] The utility model relates to the field of environmental parameter monitoring systems, in particular to devices for monitoring air parameters in clean rooms.

[0002] A method for operating a cleanroom and a control device are known, comprising a workroom, a room ventilation system, and a control device. The control device controls and / or regulates the room ventilation system. The room ventilation system creates an air exchange rate in the workroom and a pressure difference between the workroom and the surrounding space. The control device comprises at least one sensor device that records an actual value representing an operating parameter. The control device regulates the air exchange rate such that the actual value lies within the range of a predetermined value.The actual value of the particle concentration is recorded by means of a sensor device, wherein the actual value is an operating parameter of the workroom, wherein the actual value depends on the change in the air exchange rate, wherein the actual value is adjusted in accordance with a set value, the control device selects the set value depending on the control of time and / or traffic intensity [patent RU No. 2646200C2, F24F 11 / 00, 01.03.2018].

[0003] The disadvantage of the analogue is the lack of wireless data transmission and visualization of parameters in real time, a limited set of controlled parameters, as well as the complexity of implementing a multi-loop control system.

[0004] A system is known for monitoring the aerosol parameters of the air environment of an aseptic room, containing supply air ducts, supply air distributors, a test aerosol sprayer, samplers, an aerosol generator, an aerosol particle counter, pulse pipelines, collectors with a controller, wherein the test aerosol sprayer is made in the form of a curved tube with a plugged end and with holes located along its perimeter [patent RU No. 103929U1, G01N 35 / 00, 27.04.2011].

[0005] The disadvantage of the analogue is a limited set of controlled parameters, the lack of wireless data transmission and visualization of parameters in real time, as well as narrow specialization, requiring the presence of a test aerosol generator.

[0006] A device is known for monitoring the aerosol parameters of the air environment of "clean" rooms, containing coarse and intermediate air filters, a fan, a central shaft of air ducts, a generator of the initial test aerosol, a pulse pipeline, a diluent, an aerosol particle counter, aerosol sprayers installed oppositely on the diametrical axis of the cross-section of the central shaft of the air ducts, an aerosol sampler, air distributor modules with fine filters, an air flow regulator [patent RU No. 65986U1, F04D 25 / 08, H05K, 27.08.2007].

[0007] The disadvantage of the analogue is its narrow specialization in monitoring only aerosol particles, the lack of the ability to control temperature, humidity, pressure and carbon dioxide concentration, as well as the lack of wireless data transmission and visualization of parameters in real time.

[0008] The objective of the utility model is to expand the functionality of the air parameter monitoring device, provide remote monitoring and improve the accuracy of measurements.

[0009] The technical result consists in increasing the efficiency of air environment monitoring due to an expanded set of measured parameters, automatic data processing, real-time visualization and the possibility of remote access to measurement results.

[0010] The problem is solved and the technical result is achieved by a device for monitoring the air parameters of clean rooms, which includes a housing with inlet openings for uniform air intake, inside which a parameter monitoring unit, a data processing unit, a wireless data transmission unit, a data visualization unit are located, each of which is electrically connected to a power supply unit, wherein the parameter monitoring unit contains an air humidity and temperature sensor, a pressure sensor, a carbon dioxide sensor and a dust sensor located on a common printed circuit board, each of which is electrically connected to a microcontroller located in the data processing unit, the microcontroller is electrically connected to a Wi-Fi module located in the wireless data transmission unit, with the ability to transmit data to external devices, the data visualization unit is made in the form of an LCD display with an I2C interface, electrically connected to the corresponding pins of the microcontroller.

[0011] The essence of the utility model is explained by a drawing, which shows a structural diagram of a device for monitoring air parameters.

[0012] A device for monitoring air parameters in clean rooms includes a housing 1 with inlet openings for uniform air intake, inside which a parameter monitoring unit 2 is located, wherein the parameter monitoring unit 2 contains an air humidity and temperature sensor 3, a pressure sensor 4, a carbon dioxide sensor 5 and a dust sensor 6 located on a common printed circuit board, each of which is electrically connected to a microcontroller located in a data processing unit 7. The microcontroller is electrically connected to a Wi-Fi module located in a wireless data transmission unit 8, with the ability to transmit data to external devices. The data visualization unit 9 is implemented in the form of an LCD display with an I2C interface, electrically connected to the corresponding pins of the microcontroller. The data processing unit 7, the wireless data transmission unit 8, the data visualization unit 9 are also located in the housing 1, each of which is electrically connected to the power supply unit 10.

[0013] The device for monitoring clean room air parameters operates as follows.

[0014] Humidity and temperature sensor 3, pressure sensor 4, carbon dioxide sensor 5, and dust sensor 6 continuously measure the corresponding air parameters. The signals from the sensors are sent to data processing unit 7, where they are filtered, digitized if necessary by a built-in ADC, and converted into physical units using calibration coefficients. Data processing unit 7 then sends the processed data simultaneously to wireless data transmission unit 8 for remote transmission and to data visualization unit 9 for real-time display. Wireless data transmission unit 8 transmits the data to an external server or the user's smartphone. Power supply unit 10 is electrically connected to all system components and supplies them with power. This design allows for a compact device, high measurement accuracy, clarity, and the ability to remotely monitor cleanroom parameters.

[0015] Thus, the claimed utility model ensures increased efficiency of air environment monitoring due to an expanded set of measured parameters, automatic data processing, real-time visualization and the possibility of remote access to measurement results.
