Description

Technical Field

[0001] The present invention relates to an indoor air purification system, and more particularly to an indoor air purification system in which a gas detection module is electrically connected to each air purification device to realize air pollution detection and cooperative control operations.

Background Art

[0002] Suspended particles refer to solid particles or droplets contained in a gas. Since their particle size is very small, they can easily enter the human lungs through the nasal hairs in the nasal cavity, which may cause lung inflammation, asthma, or cardiovascular diseases. If other pollutants adhere to the suspended particles, the harm to the respiratory system will be further aggravated. In recent years, the problem of gas pollution has become increasingly serious. In particular, the concentration data of fine suspended particles (e.g., PM2.5) are often too high, and the concentration monitoring of gas suspended particles has attracted attention. However, because gas changes due to wind direction and wind volume, it becomes unstable. Most of the current gas quality monitoring stations for detecting suspended particles are fixed points, so the current concentration of surrounding suspended particles cannot be confirmed.

[0003] Furthermore, modern people are exposed to, for example, carbon monoxide, carbon dioxide, volatile organic compounds (VOCs), PM2.5, nitrogen monoxide, sulfur monoxide, and other gases, and even particles contained in the gas, which will affect human health and may even endanger life in serious cases. Therefore, the quality of the surrounding gas has attracted the attention of countries around the world. In order to avoid areas with poor gas quality or stay away from areas with poor gas quality, how to detect the gas quality has become a current issue.

[0004] To confirm the gas quality, it is conceivable to use a gas sensor to detect the surrounding gas. If the detection information is provided in real time, warnings can be issued to the people around, and prevention can be carried out immediately. Using a gas sensor to detect the surrounding environment is an excellent application to avoid the impact and harm on the human body caused by gas hazards in the environment.

[0005] Furthermore, the quality of indoor air is not easy to control. In addition to the quality of outdoor air, indoor air conditioning conditions and pollution sources are also the main factors affecting the quality of indoor air. Therefore, the quality of indoor air can be detected intelligently and quickly. Effectively removing air pollution sources and indoor air pollution to form a clean and safe breathable gas state, and being able to monitor the quality of indoor air instantaneously anytime and anywhere are the focuses of current research and development. Of course, when the indoor area can strictly manage the aerosol concentration according to the "CleanRoom" standard, efforts should be made to avoid the introduction, generation, and retention of particles and control the temperature and humidity within the required range. That is, in the indoor area, the quantity of suspended particles in the air is used to distinguish its level, meeting the requirements of the clean room for a safely breathable indoor area.

[0006] The air pollution detection of the currently provided indoor air purification system detects air pollution information from a gas detector and transmits it. Through communication, it is transmitted to a cloud computing service device, and the air pollution data of the outdoor area and the indoor area are received and saved to form a database of air pollution data. Based on the air pollution data, intelligent calculations are performed and compared, and a intelligently selected control command is issued to the fan of the air purification device to activate a control operation, enabling the continuous generation of a directional air flow for internal circulation in the indoor area. Air pollution is induced multiple times and passes through a filter element for filtration and removal, so that the gas state of the indoor area can reach the clean room level.

[0007] In addition, the indoor air purification system achieves real-time monitoring, real-time filtration, and purification of indoor air quality through cooperative control via a plurality of air purification devices and a control device provided indoors, promotes indoor air pollution to zero, and forms a breathable gas state, which is the main problem of the present invention. Content of the invention

[0008] The main object of the present invention is to provide an indoor air purification system including a plurality of gas detection modules, a plurality of air purification devices, and at least one central control device. By installing and electrically connecting a gas detection module to each air purification device, an air pollution detection and cooperative control operation are realized. The central control device is connected to the gas detection module and can be transmitted and connected via a selective startup mechanism with a wired communication or wireless communication handshake communication protocol. A control command signal is provided to the gas detection module to control the startup operation, air volume, and noise of the fans of the plurality of air purification devices. Air pollution passes through the filter elements of the plurality of air purification devices and is filtered, promoting the state of air pollution gas in the indoor area to zero and meeting the requirements of the cleanroom grade.

[0009] To achieve the above object, the present invention provides an indoor air purification system including a plurality of gas detection modules, a plurality of air purification devices, and a central control device. The plurality of gas detection modules include a power conversion unit, a detection element unit, a microcontroller, a wireless communication unit, and a central communication interface unit. Here, the power conversion unit inputs AC power and converts it into the required DC power output, and provides it to the detection element unit, the microcontroller, the wireless communication unit, the central communication interface unit, and the detection element unit to detect air pollution, and the air pollution data is output to the microcontroller for arithmetic processing. The microcontroller outputs a plurality of control signals; the plurality of air purification devices are installed in the indoor area and mainly include a fan, a filter element, and a drive control unit. Here, the plurality of gas detection modules are installed in the plurality of air purification devices and are electrically connected to the fan and the drive control unit. The drive control unit receives the plurality of control signals and controls the startup operation and the wind speed of the fan based on them. The fan starts up under control to guide air pollution to the filter element and is filtered through the filter element; the central control device is connected to the central control communication interface unit of the gas detection module, provides a control command signal to the microcontroller through a communication protocol connection, controls the operation of the plurality of air purification devices, and receives and displays in real time the data signal of the air pollution detected from the gas detection module; thereby, the gas detection module electrically connected within the plurality of gas detection modules receives a control command, transmits it to the drive control unit to control the startup operation of the fan, starts the fan to induce air pollution to pass through the filter element for filtration, promotes the state of the air pollution gas in the indoor area to zero, and can meet the requirements of the clean room grade.

The detection element unit 12 is a temperature and humidity detection element 12b, which detects air pollution data due to the temperature and humidity contained in the air; the detection element unit 12 is a gas detection element 12c, which detects air pollution data due to gas molecules contained in the air.

For example, the safety value of the temperature and humidity setting in the indoor area A is to keep the temperature in the indoor area A within the range of 25°C ± 3°C and the humidity within the range of 50% ± 10%. The gas detection element 12c detects the carbon dioxide (CO2) concentration in the air. When the air pollution data caused by carbon dioxide (CO2) is detected and the safety value is set, if the microcontroller 13 receives the air pollution data caused by carbon dioxide (CO2) exceeding the set safety value, it outputs a plurality of control signals. For example, the set safety value for the carbon dioxide (CO2) air pollution data in the indoor area A needs to be kept at less than 800 PPM of the air pollution data.

[0018] The microcontroller 13 receives the air pollution data output from the detection element unit 12, calculates and processes it, and outputs a plurality of control signals. Here, the air pollution data output by the detection element unit 12 is transmitted to the microcontroller 13 in the form of a serial communication (IIC) signal via an electric circuit for reception and calculation processing. And the control signals output by the microcontroller 13 include a universal asynchronous transceiver transmission (UART) signal and a general-purpose input and output (GP I / O) signal. The universal asynchronous transceiver transmission (UART) signal is transmitted via an electric circuit to and received by the air purifying device 2, the wireless communication unit 14, and the central communication interface unit 15. The general-purpose input and output (GP I / O) signal is transmitted via an electric circuit to and received by the air purifying device 2. Incidentally, as shown in FIGS. 2A and 2B, the output of the central communication interface unit 15 is connected to a communication control line for communication protocol connection transmission and the central control device 3, and the communication protocol is a wired communication transmission of the RS485 communication protocol (the solid line transmission line part in FIG. 2A). Referring to FIGS. 4A and 4B again, the gas detection module 1 can be configured in a type with an external power supply terminal. When directly using the external power supply terminal and inserting it into the power connector of the indoor area A or the outdoor area B (the gas detection module indicated by number 1 as shown in FIGS. 1A and 1B), the operation of detecting air pollution can be activated, or it can be directly constructed and electrically connected inside the air purifying device 2 such as the module type without an external power supply terminal shown in FIG. 4C (the gas detection module shown in FIG. 2A).

Here, the gas detection module 1 is electrically connected to the fan 21 and the drive control unit 23 (shown in FIG. 3C). Referring again to FIGS. 2B and 3C, the air purifying device 2 further includes a relay 24 and a communication interface device 25. Here, the relay 24 is electrically connected according to the AC power input output by the power conversion unit 11 and is connected in cooperation with the microcontroller 13 to output a control signal (general-purpose input and output (GPIO)), output AC power, and provide it to the drive control unit 23 for power control and adjustment. The communication interface device 25 connects the input according to the required 5V DC voltage output by the power conversion unit 11 and outputs a control signal (general-purpose asynchronous transceiver transmission (UART) signal) input in cooperation with the microcontroller 13. The communication control line is used to establish a communication transmission connection with the drive control unit 23 for controlling the wind speed of the fan 21 of the air purifying device 2, start the fan 21 under control, induce air pollution, and filter it through the filter element 22. In this embodiment, the communication protocol of the communication control line output by the air purifying device 2 is the RS485 communication protocol. In this embodiment, a plurality of air purifying devices 2 can be installed in the system, and each air purifying device 2 includes an address encoder (not shown) for supply and output, which is connected to the line for outputting a control signal (general-purpose input and output (GPIO)), facilitating serial connection and control of the plurality of air purifying devices 2.

[0020] Referring back to FIGS. 2A and 2B, the central control device 3 is connected to the central communication interface unit 15 of the gas detection module 1 via a communication control line, and provides a control command signal to the microcontroller 13 via a communication protocol connection to control the operations of the plurality of air purification devices 2, and to display in real time the air pollution data signal detected by the received gas detection module 1.

[0021] Referring back to FIGS. 2B and 3C, the cloud computing service device 4 receives and stores the air pollution data signals detected and output by the gas detection modules 1 of the plurality of air purification devices 2 via the router 5 wireless communication to form a database of air pollution data. And based on the air pollution data, the cloud computing service device 4 performs intelligent calculation, comparison, intelligent selection and issuance of control commands, which are transmitted and received by the gas detection modules 1 of the plurality of air purification devices 2 through the router 5 wireless communication connection, and transmitted to the drive control unit 23 to control the starting operation of the fan 21. The fan 21 is started under control, and air pollution is induced to pass through the filter element 22 and be filtered, so as to promote the state of the air pollution gas in the indoor area A to zero and meet the requirements of the clean room grade.

[0022] In addition, the gas detection module 1 of the plurality of air purifying devices 2 can also be connected to the central control device 3 via wired communication to receive air pollution data signals. The central control device 3 transmits and receives the air pollution data signals to / from the router 5 via wireless communication. Then, the air pollution data signals received via the router 5 are transmitted to and stored in the cloud computing service device 4 to form a database of air pollution data. The cloud computing service device 4 performs intelligent calculation, comparison, intelligent selection, and issues a control command, which is communicatively connected to the central control device 3. The central control device 3 transmits and receives the control command to / from the gas detection module 1 of the plurality of air purifying devices 2 via wired communication connection, and then transmits it to the drive control unit 23 to control the starting operation of the fan 21. The fan 21 is started under control, inducing air pollution to pass through the filter element 22 for filtration, promoting the air pollution gas state in the indoor area A to zero, and meeting the requirements of the clean room grade.

[0023] Under the Handshake communication protocol, the gas detection module 1 of the plurality of air purifying devices 2 can control and select wired communication or wireless communication that can operate the transmission when the wireless communication or wired communication is disconnected, select a startup mechanism. The cloud computing service device 4 receives air pollution data through an alternative startup mechanism of wired communication or wireless communication capable of transmission operation. The cloud computing service device 4 performs intelligent calculation, comparison, intelligent selection, issues a control command, connects via an alternative startup mechanism of wired communication capable of transmission operation or the wireless communication, transmits and receives it to / from the gas detection module 1 of the plurality of air purifying devices 2, re-transmits it to the drive control unit 23 to control the starting operation of the fan 21. The fan 21 is started under control, guiding air pollution to the filter element 22 for filtration, promoting the air pollution gas state in the indoor area A to zero, and meeting the requirements of the clean room grade.

[0024] In addition, when all wireless communications or wired communications are disconnected in the Handshake communication protocol, the gas detection modules 1 of the plurality of air purifying devices 2 independently perform intelligent calculation and comparison on the output air pollution data detected by the gas detection modules 1, and transmit control commands to the drive control unit 23 to control the startup operation of the fan 21. The fan 21 is started under control, and air pollution is induced to pass through the filter element 22 and be filtered, promoting the state of the air pollution gas in the indoor area A to approach zero, and meeting the requirements of the clean room grade. Note that the intelligent calculation includes artificial intelligence (AI) computing and edge computing.

[0025] From the above description, the specific implementation of the indoor air purification system in the indoor area A according to the present invention can be understood. Hereinafter, the specific implementation of the plurality of air purifying devices 2 in the indoor field A will be described. The air purifying device 2 can be installed in the indoor area A in a Build-in manner or a Plug-in manner. When the air purifying device 2 is installed in the indoor area A in a Build-in manner (as shown in FIGS. 1A and 1B), at least one circulation and return air channel C is provided in the indoor area A, which is formed on the indoor area A side by separating the surroundings with a plurality of partitions C1, and a plurality of air inlets C2 and a plurality of return air outlets C3 are provided.

[0026] The air purifying device 2 may be a gas exchanger 2a. The gas exchanger 2a is disposed in the circulation and return air channel C of the indoor area A, corresponding to the air intake C2. Also, in the outdoor area B, ventilation is performed through channel communication (not shown). The gas detection module 1 of the gas exchanger 2a receives a control command via wireless communication or wired communication, transmits it to the drive control unit 23 to control the startup operation of the fan 21, and controls at least one gas detection module 1 installed in the outdoor area B and at least one gas detection module 1 installed in the indoor area A. And the cloud computing service device 4 receives the air pollution data of the indoor area A and the outdoor area B, stores it to form a database of air pollution data, performs intelligent calculation and comparison on the air pollution data of the indoor area A and the outdoor area B. When the air pollution data of the indoor area A is higher than the air pollution data of the outdoor area B, the cloud computing service device 4 transmits a control command to the gas detection module 1 of the gas exchanger 2a and receives the control command via wireless or wired. This signal is transmitted to the drive control unit 23, the startup operation of the fan 21 is controlled, and the gas in the outdoor area B is introduced into the indoor area A for ventilation. When the air pollution data caused by the indoor area A is higher than the air pollution data caused by the outdoor area B, the cloud computing service device 4 issues a control command. The gas detection module 1 of the gas exchanger 2a receives the control command via wireless or wired communication and transmits it to the drive control unit 23 to control the startup operation of the fan 21, and introduces the gas from the outdoor area B into the indoor area A to achieve ventilation. Here, the gas detection modules 1 in the outdoor area B and the indoor area A detect the air pollution data caused by carbon dioxide (CO2). The gas detection module 1 needs to keep the detected air pollution data caused by carbon dioxide (CO2) at the air pollution data according to the set safety value less than 800 PPM. When exceeding the air pollution data according to the set safety value, the gas exchanger 2a supplies gas from the outdoor area B to the indoor area A for ventilation. Also, the gas exchanger 2a may be a new fan or a total heat exchanger.

[0027] Referring to FIGS. 1A, 1B and 3C, the air purifying device 2 may be a circulation filtration device 2b.
