Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, according to the technology described in Patent Document 1 above, there is a certain space between the exhaust assisting device and the exhaust device, and since the contaminated air moves upward from below through this space, if there is disturbance by an air current from the side of this space, the contaminated air will flow to the side and it will be difficult to capture it by the exhaust device. For this reason, in order for the exhaust device to be able to capture the contaminated air, the exhaust assisting device always needs to operate at a predetermined air volume or more regardless of the state of the contaminated air, which may not be efficient from the viewpoint of energy saving.

[0006] The present disclosure has been made in view of the above points, and can efficiently exhaust contaminated air according to the state of the contaminated air generated from the pollution source. Arranged row An object of the present disclosure is to provide an air system.

[0011] Hereinafter, with reference to the drawings, an example of a mode for carrying out the technology of the present disclosure will be described in detail. Note that components and processes having the same functions may be given the same reference numerals throughout the drawings, and redundant explanations may be omitted as appropriate. Each drawing only schematically shows the technology of the present disclosure to the extent that it can be sufficiently understood. Therefore, the technology of the present disclosure is not limited to only the illustrated examples. In addition, in the present embodiment, descriptions of configurations not directly related to the technology of the present disclosure and well-known configurations may be omitted.

[0012] [First Embodiment] FIG. 1 is a side view schematically showing an example of the configuration of an exhaust system 100 according to the first embodiment.

[0013] As shown in FIG. 1, the production apparatus 50 is an example of a pollution source, and although not particularly limited, generates polluted air Pa containing harmful substances such as volatile organic compounds (VOCs). The exhaust system 100 is an exhaust system that exhausts the polluted air Pa generated by the production apparatus 50. The exhaust system 100 is mainly installed indoors such as in a factory. The exhaust system 100 is provided on the side and above the production apparatus 50, and includes an exhaust device 40, a blower device 20, a state detection device 30, and a control device 10.

[0014] An exhaust device 40 is provided above the production device 50, and there is a certain space between the production device 50 and the exhaust device 40. The contaminated air Pa moves through this space from the production device 50 towards the exhaust device 40.

[0015] The exhaust device 40 exhausts the contaminated air Pa generated by the production device 50. Specifically, the exhaust device 40 sucks in and exhausts the contaminated air Pa within the capture region Rt among the contaminated air Pa generated by the production device 50. The capture region Rt is a region where the exhaust device 40 can suck in the contaminated air Pa, and is determined according to the performance of the exhaust device 40. The configuration of the exhaust device 40 is not particularly limited, but as an example, as shown in FIG. 1, it is desirable to use an auxiliary jet type exhaust device that enables more efficient exhaust.

[0016] The auxiliary jet type exhaust device 40 includes an exhaust port 41, an exhaust fan 42, an exhaust duct 43, a jet air outlet 44, an auxiliary jet fan 45, and an air supply duct 46. The exhaust port 41 is connected via the exhaust fan 42 and the exhaust duct 43. By operating the exhaust fan 42, the contaminated air Pa within the capture region Rt is sucked in from the exhaust port 41. Further, the jet air outlet 44 is provided around the exhaust port 41 and is connected via the auxiliary jet fan 45 and the air supply duct 46. By operating the auxiliary jet fan 45, air in a jet state is radially sent out from the jet air outlet 44.

[0017] The jet air sent out from the jet air outlet 44 can attract the surrounding contaminated air Pa, limit the suction range of the exhaust port 41, and increase the suction wind speed on the central axis of the exhaust port 41. Therefore, compared with a general exhaust device without an auxiliary jet, the contaminated air Pa can be exhausted more efficiently.

[0018] By using the auxiliary jet type exhaust device 40, the contaminated air Pa within the capture region Rt can be exhausted more efficiently.

[0019] The state detection device 30 detects distribution data representing the distribution state of the contaminated air Pa. The state detection device 30 is, for example, at least one of a visible light camera, a thermal camera, an infrared camera, a concentration sensor, a temperature sensor, and a humidity sensor. That is, the state detection device 30 may be composed of one or more cameras such as a visible light camera, a thermal camera, and an infrared camera, or may be composed of one or more multi-point sensors such as a concentration sensor, a temperature sensor, and a humidity sensor. Further, the state detection device 30 may be configured by combining one or more cameras and multi-point sensors. Further, by using various cameras and sensors alone or in combination as the state detection device 30, the distribution state of the contaminated air Pa can be accurately detected.

[0020] As an example, as shown in FIG. 1, the state detection device 30 is provided separately from the blower device 20. Further, as will be described later, the state detection device 30 may be provided integrally with the blower device 20. The installation location of the state detection device 30 is not particularly limited, but it may be installed at a location where the entire space between the production device 50 and the exhaust device 40 can be the imaging target or the detection target, and the distribution state of the contaminated air Pa moving in the space can be detected.

[0021] The blower device 20 sends air in a jet state (hereinafter referred to as "jet air") Ar to the contaminated air Pa and guides the contaminated air Pa to the capture region Rt. The blower device 20 may be one unit or a plurality of units. When a plurality of blower devices 20 are provided, the plurality of blower devices 20 are provided so as to surround the production device 50, for example. In this case, the installation interval of the blower devices 20 does not have to be constant and may be random. By providing a plurality of blower devices 20 so as to surround the production device 50, it is possible to suppress the outflow of the contaminated air Pa outside the capture region Rt over a wide range.

[0022] The installation location of the blower device 20 is not particularly limited, but it is desirable to install it at a location where it does not affect the operation, movement, etc. of the production device 50. The blower device 20 may be configured integrally with the production device 50.

[0023] The control device 10 is a controller for the exhaust system 100 and is connected to the blower device 20, the state detection device 30, and the exhaust device 40.

[0024] FIG. 2 is a block diagram showing an example of the hardware configuration of the control device 10 according to the first embodiment.

[0025] As shown in FIG. 2, the control device 10 according to the present embodiment includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, an input / output interface (I / O) 14, a storage unit 15, a display unit 16, and a connection unit 17.

[0026] The CPU 11, ROM 12, RAM 13, and I / O 14 are each connected via a bus. To the I / O 14, each functional unit including the storage unit 15, the display unit 16, and the connection unit 17 is connected. These functional units are made to be able to communicate with each other with the CPU 11 via the I / O 14.

[0027] The control unit is constituted by the CPU 11, ROM 12, RAM 13, and I / O 14. The control unit may be configured as a sub-control unit that controls a part of the operations of the control device 10, or may be configured as a part of the main control unit that controls the overall operations of the control device 10. For a part or all of each block of the control unit, for example, an integrated circuit such as an LSI (Large Scale Integration) or an IC chip set is used. Individual circuits may be used for the above-described respective blocks, or circuits in which some or all are integrated may be used. The above-described respective blocks may be provided integrally, or some blocks may be provided separately. Also, in each of the above-described blocks, a part thereof may be provided separately. For the integration of the control unit, not only LSI but also a dedicated circuit or a general-purpose processor may be used.

[0028] As the storage unit 15, for example, an HDD (Hard Disk Drive), an SSD (Solid State Drive), a flash memory, or the like is used. The control program 15A according to the present embodiment is stored in the storage unit 15. Note that this control program 15A may be stored in the ROM 12.

[0029] The control program 15A may be, for example, pre-installed in the control device 10. The control program 15A may be stored in a non-volatile non-transitory storage medium, or distributed via a network and appropriately installed in the control device 10. Examples of the non-volatile non-transitory storage medium include a CD-ROM (Compact Disc Read Only Memory), a magneto-optical disk, an HDD, a DVD-ROM (Digital Versatile Disc Read Only Memory), a flash memory, a memory card, and the like.

[0030] The display unit 16 uses, for example, a liquid crystal display (LCD) or an organic EL (Electro Luminescence) display. The display unit 16 may integrally include a touch panel. The display unit 16 receives various instructions from the user of the control device 10. The display unit 16 displays various information such as the result of processing executed according to the instructions received from the user and notifications regarding the processing.

[0031] The connection unit 17 is an interface for connecting each of the blower device 20, the state detection device 30, and the exhaust device 40.

[0032] FIG. 3 is a block diagram showing an example of the functional configuration of the control device 10 according to the first embodiment.

[0033] As shown in FIG. 3, the CPU 11 of the control device 10 according to the present embodiment functions as an acquisition unit 11A and a control unit 11B by writing the control program 15A stored in the storage unit 15 or the ROM 12 into the RAM 13 and executing it.

[0034] The acquisition unit 11A acquires distribution data representing the distribution state of the contaminated air Pa from the state detection device 30 when the exhaust device 40 exhausts the contaminated air Pa within the capture region Rt among the contaminated air Pa generated from the production device 50.

[0035] The control unit 11B enables at least one of the air volume and the wind direction of the jet air Ar sent to the contaminated air Pa from the blower device 20 to be controllable according to the acquired distribution data so that the contaminated air Pa is efficiently guided to the capture region Rt. The control unit 11B may control either one of the air volume and the wind direction of the jet air Ar, or may control both the air volume and the wind direction of the jet air Ar. Here, the air volume and the wind direction of the jet air Ar are controlled, for example, to the minimum air volume and wind direction capable of keeping the contaminated air Pa within the capture region Rt. When controlling a plurality of blower devices 20, the air volume and the wind direction of each blower device 20 are controlled so that the total air volume obtained by summing the air volumes of the plurality of blower devices 20 becomes the minimum air volume capable of keeping the contaminated air Pa within the capture region Rt.

[0036] According to the exhaust system 100 according to the present embodiment, the state detection device 30 constantly monitors the distribution state of the contaminated air Pa, and the control device 10 controls at least one of the air volume and the wind direction of the jet air Ar sent from the blower device 20 according to the distribution data acquired from the state detection device 30. Specifically, for example, if there is an external disturbance due to an air current from the side with respect to the space between the production device 50 and the exhaust device 40, the contaminated air Pa will flow to the side, and the distribution data of the contaminated air Pa will change. Then, according to the changed distribution data, at least one of the air volume and the wind direction of the jet air Ar sent from the blower device 20 is controlled so that the contaminated air Pa is efficiently guided to the capture region Rt. That is, it is not necessary to always operate the blower device 20 at an air volume equal to or greater than a predetermined value, and the blower device 20 may be adaptively controlled according to the distribution state of the contaminated air Pa. For this reason, the power consumption of the system can be suppressed, and the exhaust of the contaminated air Pa can be efficiently performed.

[0037] For example, as shown in FIG. 1 above, when a disturbance occurs from the left to the right of the production apparatus 50, the contaminated air Pa flows from the left to the right. In this case, the air volume of the blower apparatus 20 provided on the right side of the production apparatus 50 may be increased, and the blower apparatus 20 provided on the left side of the production apparatus 50 may be stopped or its air volume may be decreased. When a plurality of blower apparatuses 20 are provided, different control contents may be set for each blower apparatus 20 based on the distribution state of the contaminated air Pa.

[0038] FIG. 4(A) is a diagram schematically showing an example of a configuration in which a state detection device 30 is integrally provided in the blower device 20. FIG. 4(B) is a plan view showing a state in which a plurality of blower devices 20 shown in FIG. 4(A) surround the production device 50 and are arranged at 90-degree intervals.

[0039] As shown in FIG. 4(A), a state detection device 30 is integrally provided at the upper end of the blower device 20. By integrally providing the state detection device 30 with the blower device 20, it is not necessary to consider the installation location of the state detection device 30. In FIG. 4(A), as an example, four blower devices 20 are shown, and each blower device 20 has the same configuration.

[0040] The blower device 20 includes a blower fan 21 that blows air, a motor 22 that rotates the blower fan 21, a nozzle 23 that defines the wind direction of the air blown by the blower fan 21, an air volume changing unit 24 that changes the air volume of the air blown by the blower fan 21, and a wind direction changing unit 25 that changes the direction of the nozzle 23.

[0041] By configuring the blower device 20 as described above, at least one of the air volume and the wind direction of the blower device 20 can be changed.

[0042] As described above, the control device 10 includes a connection part 17. The input (IN) of the connection part 17 is connected to the state detection device 30, and the output (OUT) of the connection part 17 is connected to each of the air volume changing unit 24 and the wind direction changing unit 25 of the blower device 20.

[0043] The control device 10 acquires distribution data of the contaminated air Pa from the state detection device 30, and outputs, according to the acquired distribution data, a control value for controlling the air volume of the jet air Ar of the blower device 20 to the air volume change unit 24, and outputs a control value for controlling the wind direction of the jet air Ar to the wind direction change unit 25. The air volume change unit 24 changes the air volume of the jet air Ar according to the input control value, and the wind direction change unit 25 changes the direction of the nozzle 23 according to the input control value to change the wind direction of the jet air Ar.

[0044] As shown in FIG. 4(B), as an example, four blower devices 20 are arranged around the production device 50 at intervals of 90 degrees. By arranging them in this way, it is possible to guide the contaminated air Pa to the capture region Rt even when a disturbance occurs from any direction. However, if at least three blower devices 20 are arranged, it is possible to cope with disturbances from all directions. Note that the number and arrangement location of the blower devices 20 are not particularly limited. The number and arrangement location of the blower devices 20 may be determined in consideration of the layout of the production device 50 and the ease of access for the user.

[0045] Note that the control value of the air volume may be different for each blower device 20 according to the distribution data of the contaminated air Pa. The control value of the wind direction may also be different for each blower device 20 according to the distribution data of the contaminated air Pa.

[0046] Next, with reference to FIGS. 5 to 7, the blower device control process by the control device 10 will be specifically described.

[0047] FIG. 5 shows an example of the control value screen 60 according to the present embodiment. Note that in the example of FIG. 5, the case of controlling both the air volume and the wind direction of the jet air Ar is shown, but either one of the air volume and the wind direction may be controlled.

[0048] The control unit 11B of the control device 10 calculates control values for the air volume and air direction of the jet air Ar so that the contaminated air Pa is efficiently guided to the capture region Rt based on the distribution data of the contaminated air Pa, and performs control to present the calculated control values. Specifically, the control value for the air volume of the jet air Ar is, for example, a control value corresponding to the minimum air volume capable of keeping the contaminated air Pa within the capture region Rt. As an example, the control unit 11B causes the display unit 16 to display a control value screen 60 including the control values for the air volume and air direction of the blower device 20, as shown in FIG. 5. In this case, the operator grasps the control values for the air volume and air direction of each blower device 20 from the control value screen 60, and adjusts the air volume and air direction of each blower device 20 based on the grasped control values.

[0049] According to this configuration, the operator can grasp the control values presented on the control value screen 60 and adjust at least one of the air volume and air direction of the blower device 20 by the operator.

[0050] FIG. 6 is a diagram showing an example of the data table 70 according to the present embodiment. In the example of FIG. 6, the case of controlling both the air volume and air direction of the jet air Ar is shown, but either the air volume or the air direction may be controlled.

[0051] The data table 70 shown in FIG. 6 is a data table that associates a predetermined pattern (A, B, C, D, ···) for classifying the distribution data of the contaminated air Pa with the control values for the air volume and air direction of the jet air Ar sent by the blower device 20. The data table 70 is stored in the storage unit 15. The "predetermined pattern" here means, for example, a distribution state in which the contaminated air Pa is uniformly distributed as "pattern A", a distribution state in which the contaminated air Pa is biased to the right side as "pattern B", a distribution state in which the contaminated air Pa is biased to the left side as "pattern C", etc., and the distribution state of the contaminated air Pa is determined in advance for each pattern. Also, the control values for the air volume and air direction are values necessary for efficiently guiding the contaminated air Pa to the capture region Rt for each pattern. Specifically, the control value for the air volume is, for example, a control value corresponding to the minimum air volume capable of keeping the contaminated air Pa within the capture region Rt.

[0052] The control unit 11B of the control device 10 classifies the distribution data of the contaminated air Pa for each predetermined pattern, specifies a control value corresponding to the classified predetermined pattern from the data table 70, and controls the air volume and the wind direction of the jet air Ar based on the specified control value. In this case, the air volume and the wind direction of the blower device 20 are automatically controlled by the control device 10.

[0053] According to this configuration, at least one of the air volume and the wind direction of the blower device 20 can be controlled based on the control value specified by the data table 70.

[0054] FIG. 7 is a diagram showing an example of the learned model 80 according to the present embodiment. In the example of FIG. 7, the case where both the air volume and the wind direction of the jet air Ar are controlled is shown, but either one of the air volume and the wind direction may be controlled.

[0055] The learned model 80 shown in FIG. 7 is generated by performing machine learning using teacher data in which the distribution data of the contaminated air Pa is associated with the control values for the air volume and the wind direction of the jet air Ar. The learned model 80 is not particularly limited, but for example, a neural network or the like is used. The learned model 80 outputs a control value corresponding to the input distribution data. The learned model 80 is stored in the storage unit 15. The control values of the air volume and the wind direction are output as values necessary for efficiently guiding the contaminated air Pa to the capture region Rt with respect to the input distribution data. Specifically, the control value of the air volume is, for example, a control value corresponding to the minimum air volume capable of keeping the contaminated air Pa within the capture region Rt.

[0056] The control unit 11B of the control device 10 inputs the distribution data of the contaminated air Pa to the learned model 80, and controls the air volume and the wind direction of the jet air Ar based on the control value output from the learned model 80. In this case, the air volume and the wind direction of the blower device 20 are automatically controlled by the control device 10.

[0057] Note that the removal efficiency of the contaminated air Pa with respect to the air supply amount supplied from the air blower 20 may be evaluated, and the obtained evaluation result may be reflected in machine learning. The removal efficiency of the contaminated air Pa can be calculated from the amount of pollutant exhaust / the amount of pollutant generation. The amount of pollutant exhaust can be obtained by multiplying the pollutant concentration Cex in the exhaust by the exhaust amount Qex. The amount of pollutant generation can be obtained by measuring the generation amount of the contaminated air Pa.

[0058] According to this configuration, at least one of the air volume and the air direction of the air blower 20 can be controlled based on the control value output by the learned model 80.

[0059] Further, the acquisition unit 11A of the control device 10 may further acquire environmental information including at least one of the temperature around the production device 50, the humidity around the production device 50, the moving speed of the contaminated air Pa, and the physical properties of the contaminated air Pa. In this case, the control unit 11B can control at least one of the air volume and the air direction of the jet air Ar according to the distribution data of the contaminated air Pa and the environmental information. For example, when performing machine learning of the above-mentioned learned model 80, it is conceivable to include environmental information in the learning. In this case, the learned model 80 takes the distribution data of the contaminated air Pa and the environmental information as inputs and outputs a control value for at least one of the air volume and the air direction of the jet air Ar. By adding environmental information in this way, it becomes possible to control the air blower 20 more efficiently.

[0060] According to this configuration, by considering environmental information in addition to the distribution data, at least one of the air volume and the air direction of the air blower 20 can be controlled more efficiently.

[0061] Further, the control unit 11B of the control device 10 may be capable of controlling the suction amount of the contaminated air Pa of the exhaust device 40 together with at least one of the air volume and the air direction of the jet air Ar according to the distribution data of the contaminated air Pa. That is, by controlling the suction amount of the contaminated air Pa of the exhaust device 40 according to the distribution data of the contaminated air Pa, the capture effect of the contaminated air Pa can be further enhanced. Further, by controlling the suction amount of the contaminated air Pa of the exhaust device 40, it becomes possible to reduce the air volume of the blower device 20.

[0062] According to this configuration, in addition to controlling at least one of the air volume and the air direction of the blower device 20, by controlling the suction amount of the exhaust device 40, the exhaust of the contaminated air Pa can be performed more efficiently.

[0063] Next, with reference to FIG. 8, the operation of the control device 10 according to the first embodiment will be described.

[0064] FIG. 8 is a flowchart showing an example of the flow of processing by the control program 15A according to the first embodiment.

[0065] First, when the control of the blower device 20 is instructed to the control device 10, the control program 15A is started by the CPU 11, and the following steps are executed.

[0066] In step S101, the CPU 11 acquires distribution data representing the distribution state of the contaminated air Pa from the state detection device 30.

[0067] In step S102, the CPU 11 calculates control values for the air volume and the air direction of the jet air Ar sent from the blower device 20 so that the air volume becomes the minimum air volume capable of keeping the contaminated air Pa within the capture region Rt according to the distribution data acquired in step S101. Specifically, as described above, the control value of the air volume is, for example, a control value corresponding to the minimum air volume capable of keeping the contaminated air Pa within the capture region Rt.

[0068] In step S103, as an example, the CPU 11 displays a control value screen 60 including the control value calculated in step S102 on the display unit 16 as shown in FIG. 5 described above, and ends a series of processes by this control program 15A. Instead of displaying the control value screen 60, control using the data table 70 may be performed, or control using the learned model 80 may be performed.

[0069] As described above, according to this embodiment, at least one of the air volume and the air direction of the blower is controlled according to the distribution state of the contaminated air generated from the production apparatus. Therefore, the exhausted contaminated air can be efficiently exhausted.

[0070] [Second Embodiment] In the above first embodiment, the form of one exhaust system has been described. In the second embodiment, a form in which a plurality of exhaust systems are arranged side by side will be described.

[0071] FIG. 9 is a side view schematically showing an example of a configuration in which a plurality of exhaust systems 100A and 100B according to the second embodiment are arranged side by side.

[0072] As shown in FIG. 9, the production apparatus 50A and the production apparatus 50B are provided side by side. An exhaust system 100A that exhausts the contaminated air Pa generated by the production apparatus 50A is provided on the side and above the production apparatus 50A. The exhaust system 100A includes a control device 10A, a blower 20A, a state detection device 30A, and an exhaust device 40A. In addition, an exhaust system 100B that exhausts the contaminated air Pb generated by the production apparatus 50B is provided on the side and above the production apparatus 50B. The exhaust system 100B includes a blower 20B, a state detection device 30B, and an exhaust device 40B. Since the exhaust systems 100A and 100B are arranged side by side, if a disturbance occurs in one of the systems, the other system may also be affected by the disturbance. For example, if there is a disturbance due to an air current from the side in the space between the production apparatus 50A and the exhaust device 40A, jet air Ar is sent out from the blower 20A, and this jet air Ar may affect the exhaust of the adjacent exhaust system 100B.

[0073] In this embodiment, the control device 10A of the exhaust system 100A is connected to each of the blower device 20B and the state detection device 30B of the exhaust system 100B, and when a disturbance occurs in either the exhaust system 100A or the exhaust system 100B, cooperative control can be performed including the other system. In this cooperative control, for example, the air direction of the blower device 20A may be directed toward the exhaust system 100B to control the exhaust of the exhaust system 100B.

[0074] For example, when a disturbance occurs in the exhaust system 100A, the control device 10A of the exhaust system 100A takes the lead and cooperatively controls the blower device 20A of the exhaust system 100A and the blower device 20B of the exhaust system 100B. Specifically, the control device 10A acquires the distribution data of the contaminated air Pa from the state detection device 30A and the distribution data of the contaminated air Pb from the state detection device 30B. Then, the control device 10A controls at least one of the air volume and the air direction of the jet air Ar sent out from each of the blower device 20A and the blower device 20B so that the contaminated air Pa and the contaminated air Pb are kept within their respective capture regions Rt at the minimum air volume possible.

[0075] Thus, according to this embodiment, even in a form in which a plurality of production devices are arranged side by side and a plurality of exhaust systems are arranged side by side, cooperative control is executed with the system in which the disturbance has occurred as the main body. Therefore, the exhaust of the contaminated air can be efficiently performed.
