[0003] Recently, chemical accidents such as leakage of high-concentration harmful gases or harmful chemical substances have frequently occurred at various industrial sites.

[0004] Due to the problems caused by the leakage of such harmful chemical substances, the Environmental Protection Law compulsorily requires self-determination or proxy self-determination of various environmental pollutants, and in some cases, there is also a need to measure environmental pollutants in real time on site.

[0005] However, since the occurrence of chemical accidents is not recognized or spread, there is a problem of increased damage caused by chemical accidents. In addition, due to insufficient information or inaccurate transmission of information related to chemical accidents, there is a problem of being unable to respond quickly to chemical accidents.

[0006] In order to minimize the harm of leaked chemical substances and respond quickly, it is necessary to study an alarm providing system that notifies surrounding people when harmful chemical substances or chemical substances above the leakage reference value leak at industrial sites.

[0052] - Chemical substance leakage monitoring system

[0053] Figure 1 Briefly shows an exemplary structure of a chemical substance leakage monitoring system 1 in one implementation.

[0054] Refer to Figure 1 , a chemical substance leakage monitoring system 1 in one embodiment may include: a central server 10 that manages chemical substance leakage monitoring processing; a computing device 20 that performs necessary calculations to provide a chemical substance leakage alarm; and a chemical substance leakage alarm providing system 30 that detects chemical substances and can provide a chemical substance leakage alarm. The central server 10, the computing device 20, and the chemical substance leakage alarm providing system 30 can communicate with each other through a network.

[0055] Specifically, a network refers to a connection structure that enables each node, such as the central server 10, the computing device 20, and the chemical substance leakage alarm providing system 30, to exchange information with each other. As an example of such a network, it includes a 3rd Generation Partnership Project (3GPP) network, a Long Term Evolution (LTE) network, a World Interoperability for Microwave Access (WIMAX) network, the Internet, a Local Area Network (LAN), a Wireless Local Area Network (Wireless LAN), a Wide Area Network (WAN), a Personal Area Network (PAN), a Bluetooth network, a satellite broadcast network, an analog broadcast network, a Digital Multimedia Broadcasting (DMB) network, etc., but is not limited thereto.

[0056] Furthermore, the chemical substance leakage monitoring system 1 may further include at least one fixed sensor (not shown) and at least one fixed camera (not shown).

[0057] At least one fixed sensor may include at least one of a wind direction sensor, a wind speed sensor, and a temperature sensor disposed around a monitoring target (e.g., a chemical substance processing device, a chemical substance processing plant, etc.). However, it is not limited thereto, and at least one fixed sensor may include various sensors other than the above-mentioned multiple sensors.

[0058] At least one fixed camera may include at least one of a thermal imaging camera, an RGB camera, and a depth camera disposed around a monitoring target. However, it is not limited thereto, and at least one fixed camera may include various cameras other than the above-mentioned exemplified cameras.

[0059] The central server 10 can process various physical parameters related to the monitoring target and data related to images collected by at least one fixed sensor, at least one fixed camera, and the chemical substance leakage alarm providing system 30 disposed around the monitoring target to calculate information related to an expected leakage position of the expected leakage chemical substance and store it. However, it is not limited thereto, and a separate computing device 20 or the chemical substance leakage alarm providing system 30 may also directly process various physical parameters related to the monitoring target and data related to images to perform chemical substance leakage monitoring processing.

[0060] For example, the central server 10 or the computing device 20 may detect whether a chemical substance is leaking based on an image (thermal imaging image or RGB image) of the periphery of the monitored object acquired by at least one fixed camera. In this case, the central server 10 or the computing device 20 may use a deep learning method to detect whether a chemical substance is leaking based on the image of the periphery of the monitored object.

[0061] Moreover, the central server 10 or the computing device 20 may calculate the diffusion pattern of the leaked chemical substance based on data related to the wind direction, wind speed, temperature and the image of the periphery of the monitored object, and may generate data related to the initial expected leakage position of the chemical substance by backtracking the diffusion pattern. The data related to the initial expected leakage position generated by the central server 10 or the computing device 20 may be transmitted via a network to the chemical substance leakage alarm providing system 30.

[0062] The chemical substance leakage alarm providing system 30 may provide various user alarms to the user based on various data from the central server 10 or the computing device 20 or based on at least one of environmental information such as wind direction, wind speed, temperature and chemical substance information detected by itself.

[0063] Refer to Figures 5 to 15 to illustrate the method by which the chemical substance leakage alarm providing system 30 provides various user alarms according to various leakage states.

[0064] - Chemical Substance Leakage Alarm Providing System

[0065] Figure 2 is a block diagram of the chemical substance leakage alarm providing system 30 according to an embodiment. Figure 3 For illustrating the exemplary structure of the chemical substance leakage alarm providing system 30 according to an embodiment. Figure 4 For illustrating the monitoring area MA of the chemical substance leakage alarm providing system. Figure 5 is a block diagram of the controller 100.

[0066] Refer to Figure 2 , the chemical substance leakage alarm providing system 30 according to an embodiment may include a controller 100, a chemical substance detection device 110, an environmental information collection sensor 120 and an alarm device 130.

[0067] The controller 100 may generate a plurality of alarm control signals based on various data detected by the chemical substance detection device 110 and the environmental information collection sensor 120.

[0068] The alarm device 130 may provide various user alarms to the user according to the alarm control signals transmitted from the controller 100.

[0069] Moreover, the chemical substance leakage alarm providing system 30 may further include an image camera 140 that captures images of external objects.

[0070] The controller 100 can control the operations of the chemical substance detection device 110, the environmental information collection sensor 120, the alarm device 130, and the image camera 140. Specifically, the controller 100 can control the chemical substance detection device 110 and the environmental information collection sensor 120 to detect chemical substance information and can detect environmental information.

[0071] Moreover, the controller 100 can control the postures of the chemical substance detection device 110 and the environmental information collection sensor 120.

[0072] Moreover, the controller 100 can generate an alarm control signal for controlling the alarm device 130 based on at least one of the chemical substance information and the environmental information.

[0073] The chemical substance detection device 110 can remotely detect minute chemical substances in solid, liquid, or gaseous states. Specifically, the chemical substance detection device 110 can detect the types and concentrations of chemical substances in solid, liquid, or gaseous states spreading in the air.

[0074] For example, the chemical substance detection device 110 can use an analysis device applying the FT-IR method to remotely detect minute chemical substances in solid, liquid, or gaseous states. Moreover, the chemical substance detection device 110 may further include a thermal imaging camera and can detect the characteristics of chemical substances based on the images captured by the thermal imaging camera.

[0075] However, the present invention is not limited thereto. Besides the analysis device applying the FT-IR method and the thermal imaging camera, the chemical substance detection device 110 can use various types of devices to remotely detect chemical substances.

[0076] The chemical substance information detected by the chemical substance detection device 110 can be used to generate an alarm control signal for controlling the alarm device 130.

[0077] The environmental information collection sensor 120 may include at least one of a wind speed sensor, a wind direction sensor, and a temperature sensor.

[0078] The environmental information collection sensor 120 can detect environmental information such as the wind speed, wind direction, and temperature of the surrounding environment. The environmental information detected by the environmental information collection sensor 120 can be used to predict the diffusion pattern of the leaked chemical substances.

[0079] The alarm device 130 may provide a user alarm including at least one of an alarm sound, alarm lighting, and alarm vibration according to an alarm control signal transmitted from the controller 100. For example, the alarm device 130 may include at least one of a speaker, a lighting device, and a vibration device.

[0080] Multiple leakage states of the chemical substance may be determined according to at least one of the diffusion patterns of the chemical substance predicted based on the chemical substance information detected by the chemical substance detection device 110 and the surrounding environment information detected by the environmental information collection sensor 120. The alarm device 130 may provide multiple forms of user alarms corresponding to the multiple leakage states.

[0081] For example, the alarm device 130 may provide a first user alarm corresponding to a first leakage state of the chemical substance, provide a second user alarm corresponding to a second leakage state different from the first leakage state, and provide a third user alarm corresponding to a third leakage state different from the first and second leakage states.

[0082] Among them, the first user alarm, the second user alarm, and the third user alarm may be in different forms. For example, the first user alarm may include an alarm sound in a first mode, the second user alarm may include an alarm sound in a second mode and alarm lighting in a first color, and the third user alarm may include an alarm sound in a third mode and alarm lighting in a second color.

[0083] As described above, the alarm device 130 may provide different user alarms according to the leakage states of different chemical substances. Thus, the user can quickly identify various situations and take appropriate countermeasures to suppress the spread of accidents caused by harmful chemical substances to the human body.

[0084] The image camera 140 may capture an image of an external object. The image camera 140 may include at least one of a thermal imaging camera or an RGB camera.

[0085] The image camera 140 may obtain image information of a detection object by detecting an optical signal output from a light source and reflected by the detection object. In this specification, the image camera 140 may include a light source, a pixel array, and a light detection circuit. The light source may include multiple light-emitting devices that output optical signals with wavelengths in a specific band (for example, vertical cavity surface emitting lasers (VCSELs), light-emitting diodes (LEDs), etc.). The pixel array may include multiple pixels, and each pixel may include multiple light detection devices (for example, photodiodes, etc.) and color filters (for example, RGB filters).

[0086] Moreover, the image camera 140 may further include a depth camera. The depth camera may be referred to as a distance sensor. For example, the distance sensor is a lidar device.

[0087] The image camera 140 may have a single camera structure including at least one of a thermal imaging camera and an RGB camera and a depth camera. In this case, there is an advantage of forming a compact form factor of the image camera 140.

[0088] The image captured by the image camera 140 can be used to detect the leakage of chemical substances. Specifically, the image captured in real time by the image camera 140 can be analyzed to determine whether there is a leakage of chemical substances.

[0089] Refer to Figure 3 As shown in, the chemical substance leakage alarm providing system 30 according to an embodiment may include a main housing 70 inside which a controller 100, an environmental information collection sensor 120, and an image camera 140 are provided.

[0090] The main housing 70 provides an internal space for setting the controller 100, the environmental information collection sensor 120, and the image camera 140, and can prevent the controller 100, the environmental information collection sensor 120, and the image camera 140 from being damaged by external impacts. In this case, the detection part of the environmental information collection sensor 120 and the lens part of the image camera 140 may be exposed to the outside of the main housing 70.

[0091] However, the present invention is not limited thereto, and the environmental information collection sensor 120 and the image camera 140 may also be provided outside the main housing 70.

[0092] A fixing frame 80 may be provided at the lower part of the main housing 70. The fixing frame 80 can be fixed to the position where the chemical substance leakage alarm providing system 30 is installed.

[0093] For example, the fixing frame 80 may be in the form of a tripod including a first leg 81, a second leg 82, and a third leg 83. However, the present invention is not limited thereto, and the fixing frame 80 may be in various forms other than the tripod form.

[0094] A chemical substance detection device 110 may be provided on the main housing 70. A first inclined part 90 may be provided between the main housing 70 and the chemical substance detection device 110.

[0095] The chemical substance detection device 110 may be connected to the main housing 70 through the first inclined part 90, and the driving of the first inclined part 90 may be controlled to change the posture of the chemical substance detection device 110. For example, as the first inclined part 90 is driven, the chemical substance detection device 110 can rotate up, down, left, and right.

[0096] On the other hand, a second inclined portion 91 may be provided between the fixed frame 80 and the main outer cover 70. The main outer cover 70 may be connected to the fixed frame 80 through the second inclined portion 91, and the driving of the second inclined portion 91 is controlled to change the posture of the main outer cover 70. For example, as the second inclined portion 91 is driven, the main outer cover 70 can rotate up, down, left, and right.

[0097] The alarm device 130 may be connected to the chemical substance detection device 110. For example, the alarm device 130 may be provided below the chemical substance detection device 110.

[0098] However, the present invention is not limited thereto. The alarm device 130 is not connected to the chemical substance detection device 110, but may be provided separately. For example, the alarm device 130 may be provided inside the main outer cover 70 or outside the main outer cover 70.

[0099] Refer to Figure 4 , the chemical substance leakage alarm providing system 30 can be fixed at a specific position and can observe the monitoring area MA separated by a specified distance.

[0100] For example, the chemical substance leakage alarm providing system 30 can use the image camera 140 to capture images of the monitoring area MA in real time and use the chemical substance detection device 110 to detect chemical substance information in the monitoring area MA. Among them, the monitoring area MA can be various industrial sites where chemical substances can leak, such as semiconductor factories.

[0101] Figure 5 It is a block diagram of the controller 100.

[0102] Refer to Figure 5 , the controller 100 may include a processor 101, a memory 102, a main input unit 103, and a communication unit 104. And the controller 100 may further include a main input unit 103 connected to the processor 101.

[0103] At least one program containing instructions may be stored in the memory 102. The at least one program can be run by the processor 101.

[0104] The processor 101 may perform preset work based on the input signal input from the main input unit 103. The main input unit 103 may be provided on the main outer cover 70. And the main input unit 103 may be a button type or dial type input device, but is not limited thereto. The power on / off of the controller 100 can be controlled through the main input unit 103.

[0105] The communication unit 104 can communicate with the processor 101, the chemical substance detection device 110, the environmental information collection sensor 120, the alarm device 130, and the image camera 140 by means of Bluetooth, infrared communication, RFID, WLAN, Wibro, etc. For example, data on chemical substances obtained by the chemical substance detection device 110, data on environmental information detected by the environmental information collection sensor 120, and data on images captured by the image camera 140 can be transmitted to the communication unit 104.

[0106] Moreover, the communication unit 104 can communicate with an external device to send and receive data. For example, the communication unit 104 can communicate with the central server 10 and the computing device 20.

[0107] The processor 101 can run the programs stored in the memory and generate an alarm control signal based on various data received from the chemical substance detection device 110, the environmental information collection sensor 120, and the image camera 140. Refer to Figures 6 to 15 for the method by which the processor 101 generates an alarm control signal and the alarm device 130 provides a user alarm.

[0108] - Method for providing a chemical substance leakage alarm.

[0109] Figure 6 is a flowchart of a method S100 for providing a chemical substance leakage alarm according to an embodiment. Figure 7 It is used to illustrate the alarm data set 40 in which various chemical substance leakage states stored in the memory 102 are matched with multiple alarm control signals. Figure 8 It is used to illustrate that in one embodiment, the camera 140 designates the leakage area of the chemical substance.

[0110] Refer to Figure 6 In one embodiment, the method S100 for providing a chemical substance leakage alarm can use the chemical substance leakage monitoring system 1 including the chemical substance leakage alarm providing system 30 to provide a chemical substance leakage alarm.

[0111] The method S100 for providing a chemical substance leakage alarm may include a step S110 of detecting external environmental information, a step S120 of obtaining data on chemical substances, a step S130 of predicting the diffusion pattern of chemical substances, a step S140 of detecting chemical substance information, and a step S150 of providing a user alarm.

[0112] In the step S110 of detecting external environmental information, the controller 100 can use the environmental information collection sensor 120 to detect the external environmental information of the chemical substance leakage alarm providing system 30. Among them, the environmental information may include information related to at least one of wind speed, wind direction, and temperature detected by using the environmental information collection sensor 120.

[0113] In step S120 of acquiring data of a chemical substance, the controller 100 can use the chemical substance detection device 110 to acquire data of the chemical substance. The chemical substance detection device 110 can acquire data of the chemical substance leaking from the monitoring area at a position separated from the monitoring area.

[0114] On the other hand, referring to Figure 8 , in step S120 of acquiring data of a chemical substance, the processor 101 can specify the leakage areas 51, 52 of the chemical substance by analyzing the image 50 of the monitoring area captured by the image camera 140.

[0115] For example, the processor 101 can use an artificial neural network to specify the leakage area 51 of the first chemical substance and the leakage area 52 of the second chemical substance based on the image 50 of the monitoring area. Among them, the leakage area 51 of the first chemical substance and the leakage area 52 of the second chemical substance can be areas respectively including the discharge ports discharging the chemical substances.

[0116] The processor 101 can control the posture of the chemical substance detection device 110 so that the chemical substance detection device 110 faces the leakage area 51 of the first chemical substance and the leakage area 52 of the second chemical substance. Thereby, data of the chemical substance related to the area where the chemical substance leaks can be acquired more precisely.

[0117] In step S130 of predicting the diffusion pattern of the chemical substance, the processor 101 can predict the diffusion pattern of the chemical substance leaking from the detection area based on the environmental information.

[0118] Specifically, the processor 101 can use information related to at least one of wind speed, wind direction, and temperature to calculate the diffusion pattern of the chemical substance. And the processor 101 can reverse the diffusion pattern of the chemical substance to calculate the coordinates of the expected leakage position of the chemical substance.

[0119] In this case, the processor 101 can use an artificial neural network (ANN) to calculate the diffusion pattern of the chemical substance and the coordinates of the expected leakage position.

[0120] Among them, the artificial neural network (ANN) can include a deep neural network (DNN, Deep Neural Network), a convolutional neural network (CNN, Convolutional Neural Network), a recurrent neural network (RNN, Recurrent Neural Network), or a generative adversarial network (GAN, Generative Adversarial Network), and can be formed inside the processor 101 or formed as a separate processor outside the processor 101.

[0121] In step S140 of detecting chemical substance information, the processor 101 can detect chemical substance information based on the data of the chemical substance. For example, the chemical substance information can be information related to at least one of the type or concentration of the chemical substance.

[0122] In step S150 of providing a user alert, the processor 101 can provide a user alert based on at least one of the diffusion pattern of the chemical substance and the chemical substance information.

[0123] Specifically, the processor 101 can generate a variety of alert control signals according to an alert data set 40 in which a variety of chemical substance leakage states set based on at least one of the diffusion pattern of the chemical substance and the chemical substance information are matched with a variety of alert control signals.

[0124] The alert control signals generated by the processor 101 can be transmitted to the alert device 130 through the communication unit 104. Thus, the alert device 130 can provide a variety of forms of user alerts.

[0125] Refer to Figure 7 , detect the allowable leakage chemical substances included in the list of allowable leakage chemical substances preset and stored in the memory 102. When in the first state where it is determined that the diffusion pattern of the allowable leakage chemical substance exceeds the reference diffusion pattern range, the processor 101 can generate a first alert control signal.

[0126] Moreover, detect the non-allowable leakage chemical substances that are not included in the list of allowable leakage chemical substances. When in the second state where it is determined that the diffusion pattern of the non-allowable leakage chemical substance is within the reference diffusion pattern range, the processor 101 can generate a second alert control signal.

[0127] Among them, the range of the diffusion pattern can include at least one of the diffusion speed and diffusion range of the chemical substance.

[0128] Furthermore, detect the non-allowable leakage chemical substances that are not included in the list of allowable leakage chemical substances. When in the third state where it is determined that the diffusion pattern of the non-allowable leakage chemical substance exceeds the reference diffusion pattern range, the processor 101 can generate a third alert control signal.

[0129] As described above, different user alerts are provided according to the leakage states of different chemical substances. Thus, the user can quickly identify various situations and take appropriate countermeasures to suppress the spread of accidents caused by harmful chemical substances to the human body.

[0130] Figure 9 It is a flowchart of a method S200 for providing a chemical substance leakage alert for another embodiment.

[0131] Figure 9The steps S210, S220, S230, and S240 of the chemical substance leakage alarm providing method S200 are substantially the same as Figure 6 the steps S110, S120, S130, and S140 of the chemical substance leakage alarm providing method S100.

[0132] During the description of Figure 9 the process, the content repeated with Figure 10 will be omitted.

[0133] Referring to Figure 9 , the chemical substance leakage alarm providing method S200 may include step S210 of detecting external environment information, step S220 of obtaining data of chemical substances, step S230 of predicting the diffusion pattern of chemical substances, step S240 of detecting chemical substance information, step S250 of determining whether the detected chemical substance is included in the list of allowed leakage chemical substances, step S260 of providing a first user alarm, step S270 of determining whether the range of the diffusion pattern of the detected chemical substance exceeds the range of the reference diffusion pattern, and step S280 of providing a second user alarm.

[0134] In step S250 of determining whether the detected chemical substance is included in the list of allowed leakage chemical substances, the processor 101 may determine whether the detected chemical substance is included in the list of allowed leakage chemical substances preset and stored in the memory 102. The chemical substances included in the list of allowed leakage chemical substances are the chemical substances that are generally leaked at the corresponding industrial site and may be harmful to the human body.

[0135] When it is determined that the detected chemical substance is included in the list of allowed leakage chemical substances, the processor 101 may return to step S210 again.

[0136] When it is determined that the detected chemical substance is not included in the list of allowed leakage chemical substances, the processor 101 may execute step S250.

[0137] In step S260 of providing a first user alarm, the processor 101 may generate a first alarm control signal for detecting the state of the chemical substance that is not included in the list of allowed leakage chemical substances.

[0138] The first alarm control signal may be transmitted to the alarm device 130, whereby the alarm device 130 may provide a first user alarm corresponding to the first alarm control signal.

[0139] For example, the first user alarm may include at least one of an alarm sound in a first mode and an alarm illumination in a first color.

[0140] In step S270 of determining whether the range of the diffusion pattern of the detected chemical substance exceeds the range of the reference diffusion pattern, the processor 101 may determine whether the diffusion range of the diffusion pattern of the chemical substance not included in the list of allowed leakage chemical substances exceeds the preset range of the reference diffusion pattern.

[0141] Among them, the range of the diffusion pattern may include at least one of the diffusion speed and the diffusion range of the chemical substance.

[0142] For example, in step S230, it may be determined whether the diffusion speed and the diffusion range of the chemical substance calculated based on the predicted diffusion pattern of the chemical substance exceed the range of the reference diffusion pattern preset and stored in the memory 102. The range of the reference diffusion pattern can be preset by the user or can be updated in real time by the server 10 or the computing device 20.

[0143] When it is determined that the diffusion range of the diffusion pattern of the chemical substance not included in the list of allowed leakage chemical substances does not exceed the preset range of the reference diffusion pattern, the method for providing a chemical substance leakage alarm by the processor 101 will end.

[0144] When it is determined that the diffusion range of the diffusion pattern of the chemical substance not included in the list of allowed leakage chemical substances exceeds the preset range of the reference diffusion pattern, the processor 101 may execute step S280.

[0145] In step S280 of providing the second user alarm, the processor 101 may generate a second alarm control signal corresponding to the state where the diffusion range of the diffusion pattern of the chemical substance not included in the list of allowed leakage chemical substances exceeds the preset reference diffusion pattern.

[0146] The second alarm control signal may be transmitted to the alarm device 130, whereby the alarm device 130 may provide a second user alarm corresponding to the second alarm control signal.

[0147] For example, the second user alarm may include at least one of an alarm sound of a second mode different from the first mode and an alarm illumination of a second color different from the first color.

[0148] Figure 10 Flowchart of the method S300 for providing a chemical substance leakage alarm for another embodiment. Figure 11 Used to illustrate the steps of photographing the first target detection area a1 and the second target detection area a2. Figure 12 Used to illustrate the steps of determining the first pose of the image camera 140.

[0149] Figure 10 Steps S370, S371, S380, and S381 can substantially be respectively the same as Figure 9The steps S250, S260, S270, and S280 of the chemical substance leakage alarm providing method S200 are the same.

[0150] During the description Figure 10 of Figure 9 repeated content will be omitted.

[0151] Referring to Figure 10 , the chemical substance leakage alarm providing method S300 may include: step S310 of designating a plurality of target detection areas; step S320 of photographing any first target detection area a1 and second target detection area a2 among the plurality of target detection areas; step S330 of determining a first posture of the image camera 140 for photographing in a manner that prevents the first target detection area a1 from overlapping with the second target detection area a2; step S340 of determining a second posture of the chemical substance detection device 110; step S350 of detecting chemical substance information for the first target detection area and the second target detection area; step S360 of predicting a diffusion pattern of the chemical substance; step S370 of determining whether the detected chemical substance is included in the list of allowable leakage chemical substances; step S371 of providing a first user alarm; step S380 of determining whether the range of the diffusion pattern of the detected chemical substance exceeds a reference diffusion pattern range; and step S381 of providing a second user alarm.

[0152] In step S310 of designating a plurality of target detection areas, the processor 101 may designate a plurality of target detection areas based on three-dimensional spatial modeling data of the monitoring area.

[0153] For example, referring to Figure 11 , the processor 101 may use an artificial neural network to designate a plurality of target detection areas a1, a2, a3 of chemical substances that may leak based on three-dimensional spatial modeling data related to the monitoring area provided by the central server 10 or the computing device 20.

[0154] Among them, the first target detection area a1 may be the entrance of the first discharge port k1, the second target detection area a2 is the entrance of the second discharge port k2, and the third target detection area a3 is the entrance of the third discharge port k3.

[0155] In step S320 of photographing any first target detection area a1 and second target detection area a2 among the plurality of target detection areas, the processor 101 may cause the image camera 140 to photograph the first target detection area a1 and the second target detection area a2. In this case, the processor 101 may control the operation of the second inclination part 91 so that the image camera 140 photographs the first target detection area a1 and the second target detection area a2 in various postures.

[0156] In this case, asFigure 12 As shown in part (a) thereof, the image camera 140 can capture an image of the overlapping state of the first target detection area a1 and the second target detection area a2. Thus, in fact, chemicals can be discharged from the second row of outlets k2, and the image camera 140 can capture an image showing that chemicals are discharged from the first row of outlets k1 located on the front surface of the second row of outlets k2.

[0157] Thus, in order to obtain chemical substance data related to the first row of outlets k1, the processor 101 can control the operation of the first inclined portion 90 to control the posture of the chemical substance detection device 110 so that the chemical substance detection device 110 faces the first row of outlets k1.

[0158] In this case, in fact, the first row of outlets k1 that does not discharge chemicals is detected for chemicals, so the accuracy of the method for providing an alarm based on chemical substance information may be reduced.

[0159] In step S330 of determining the first posture of the image camera 140 that captures images in a manner that prevents the first target detection area a1 from overlapping with the second target detection area a2, during the process in which the processor 101 changes the posture of the image camera 140 in real time and captures the monitoring area, the first posture of the image camera 140 that captures images in a manner that prevents the first target detection area a1 from overlapping with the second target detection area a2 can be determined.

[0160] For example, as Figure 12 shown in part (b) thereof, the processor 101 can change the posture of the image camera 140 in real time so that the image camera 140 can capture a state in which the first target detection area a1 and the second target detection area a2 do not overlap.

[0161] In step S340 of determining the second posture of the chemical substance detection device 110, the processor 101 can determine the second posture of the chemical substance detection device 110 based on the first posture of the image camera 140.

[0162] Among them, the second posture can be the posture in which the chemical substance detection device 110 faces the second target detection area a2 where chemicals actually leak.

[0163] For example, the image camera 140 can analyze an image in which the first target detection area a1 and the second target detection area a2 do not overlap captured in the first posture to control the operation of the first inclined portion 90 and change the posture of the chemical substance detection device 110 so that the chemical substance detection device 110 faces the second target detection area a2 designated as the position where chemicals leak.

[0164] In step S350 of detecting chemical substance information for the first target detection area a1 and the second target detection area a2, the processor 101 can operate the chemical substance detection device 110 to obtain data on chemical substances related to the first target detection area a1 and the second target detection area a2.

[0165] In step S360 of predicting the diffusion pattern of the chemical substance, the processor 101 can use the environmental information collection sensor 120 to detect external environmental information and predict the diffusion pattern of the chemical substance based on the environmental information.

[0166] As described above, the processor 101 can change the postures of the image camera 140 and the chemical substance detection device 110, detect the leaked chemical substance in a state where any first target detection area a1 and the second target detection area a2 among the multiple target detection areas do not overlap, and provide an appropriate user alert based on this.

[0167] Figure 13 FIG. is a flowchart of a chemical substance leakage alert providing method S400 according to still another embodiment. Figure 14 For explaining Figure 13 FIG. is a flowchart of step S440 for correcting the prediction result of the first diffusion pattern. Figure 15 For explaining Figure 14 step S440 for correcting the prediction result of the first diffusion pattern.

[0168] Figure 13 Steps S450, S460, S470, and S480 of Figure 9 are substantially the same as steps S250, S260, S270, and S280 of the chemical substance leakage alert providing method S200 of

[0169] During the description of Figure 13 the content that repeats with Figure 9 will be omitted.

[0170] Referring to Figure 13 , the chemical substance leakage alert providing method S400 may include: step S410 of designating multiple target detection areas; step S420 of obtaining data on the first chemical substance in the first target detection area a4; step S430 of predicting the first diffusion pattern of the chemical substance leaked from the first target detection area a4; step S440 of correcting the prediction result of the first diffusion pattern; step S450 of determining whether the detected chemical substance is included in the list of permitted leaked chemical substances; step S460 of providing a first user alert; step S470 of determining whether the range of the diffusion pattern of the detected chemical substance exceeds the range of the reference diffusion pattern; and step S480 of providing a second user alert.

[0171] In step S410 of specifying a plurality of target detection regions, the processor 101 may specify a plurality of target detection regions based on the three-dimensional spatial modeling data of the monitoring region.

[0172] For example, referring to Figure 15 , the processor 101 may use an artificial neural network to specify a plurality of target detection regions a4, a5, a6, a7, a8 where chemical substances may leak, based on the three-dimensional spatial modeling data related to the monitoring region provided by the central server 10 or the computing device 20.

[0173] Among them, the first target detection region a4 may be the entrance of the first discharge port k4, the second target detection region a5 may be the entrance of the second discharge port k5, the third target detection region a6 may be the entrance of the third discharge port k6, the fourth target detection region a7 may be the entrance of the fourth discharge port k7, and the fifth target detection region a8 may be the entrance of the fifth discharge port k8.

[0174] In step S420 of obtaining data on the first chemical substance related to the first target detection region a4, the processor 101 may control the chemical substance detection device 110 to obtain data on the chemical substance in any first target detection region a4 among the plurality of target detection regions a4, a5, a6, a7, a8.

[0175] In step S430 of predicting the first diffusion pattern of the chemical substance leaking from the first target detection region a4, the processor 101 may control the environmental information collection sensor 120 to predict the external environmental information and predict the first diffusion pattern of the chemical substance leaking from the first target detection region a4 based on the environmental information.

[0176] In this case, the external environmental information detected by the environmental information collection sensor 120 provides the environmental information around the chemical substance leakage alarm system 30 set at a position separated from the first target detection region a4 by a specified distance. Therefore, the first diffusion pattern predicted based on this may not be very accurate.

[0177] In step S440 of correcting the prediction result of the first diffusion pattern, the processor 101 may correct the prediction result of the first diffusion pattern based on the second diffusion pattern of the chemical substance leaking from a second target detection region different from the first target detection region.

[0178] Specifically, referring to Figure 14 , in step S440 of correcting the prediction result of the first diffusion pattern, the processor 101 may group at least one other target detection region within the critical range from the first target detection region a4 and the first target detection region a4 (step S441).

[0179] For example, the processor 101 may group a second target detection area a5 within a critical range from the first target detection area a4 into the first target detection area a4 and a first group G1. The critical range may be preset by the user or may be transmitted from the central server 10 or the computing device 20.

[0180] Moreover, in the step S440 of correcting the prediction result of the first diffusion pattern, the processor 101 may analyze an image related to the second target detection area a5 captured by the image camera 140, so as to calculate a second diffusion pattern of the chemical substance leaking from the second target detection area a5. The processor 101 may calculate a correction value of the first diffusion pattern based on the second diffusion pattern (step S442).

[0181] Furthermore, in the step S440 of correcting the prediction result of the first diffusion pattern, the processor 101 may use the correction value of the first diffusion pattern to correct the predicted first diffusion pattern.

[0182] As described above, the accuracy of the chemical substance leakage alarm providing method based on the corrected diffusion pattern can be improved by correcting the diffusion pattern of the detected chemical substance.
