[0068] Figure 1 A schematic diagram of the structure of the multi-spectral gas detection system provided in an embodiment of the present invention; Figure 1 As shown, a multi-spectral gas detection system comprises:

[0069] The case 100 is sleeved outside the movement 150, and includes a main housing 110 and a first side panel 120; an exhaust port 111 is provided at the inner bottom of the main housing 110, and a first air inlet 121, a second air inlet 123 and a hardware interface 124 are provided on the first side panel 120;

[0070] The chassis 100 further includes:

[0071] A buzzer 112, a control switch 113, an indicator light 114 and a case handle 115 are arranged on the top of the outer side of the main housing 110; and,

[0072] A fan assembly 116 and a pulley assembly 117 are disposed on the outer bottom of the main housing 110 .

[0073] The second side plate 130 and the third side plate 140 ; ​​the first side plate 120 , the second side plate 130 and the third side plate 140 are disposed around the outside of the main housing 110 to form the chassis 100 .

[0074] In a specific embodiment, Figure 2 A schematic diagram of the structure of a chassis 100 in a multi-spectral gas detection system provided by an embodiment of the present invention; see Figure 1-2For the multi-spectral gas detection system, the chassis 100 includes a main shell 110 and multiple side panels, namely a first side panel 120, a second side panel 130 and a third side panel 140. The multiple side panels are arranged around the outside of the main shell 110 to together constitute the chassis 100; in the chassis 100, the main shell 110 can be an aluminum alloy machined part designed as a desktop chassis 100 shape, and the first side panel 120, the second side panel 130 and the third side panel 140 are all sheet metal parts, one end of which is fixedly connected to the main shell 110 by screws, and the other end is detachably connected to the main shell 110 by a hinge, so that the detection system is easy to repair internal faults.

[0075] A control switch 113, an indicator light 114, and a buzzer 112 may be provided on the outer side of the top of the chassis 100, so that the user can determine the working status of the detection system during use and intuitively receive prompt information related to the gas identification results; chassis handles 115 may be symmetrically provided at both ends of the outer side of the top of the chassis 100 to facilitate carrying and moving the detection system; a pulley group 117 and a fan group 116 may be provided on the outer side of the bottom of the chassis 100, wherein the pulley group 117 may include at least two pulleys, and the fan group 116 may include at least two fans, so as to ensure the heat dissipation performance of the detection system, as well as the convenience and stability during movement.

[0076] An exhaust port 111 is also provided on the inner side of the bottom of the chassis 100 . The number of the exhaust ports 111 is the same as the number of the first air inlets 121 , and is used to connect each detection module so that the gas to be detected is discharged from the exhaust port 111 to the external environment after being identified by the detection module.

[0077] The first side panel 120 may be provided with at least a first air inlet 121, a second air inlet 123 and a hardware interface 124, wherein the first air inlet 121 is used to receive the gas to be detected, and the number of the first air inlets 121 matches the number of detection modules, that is, each first air inlet 121 may be connected to a corresponding detection module, and each first air inlet 121 is independent so that each detection module can receive the same gas to be detected; at the same time, in order to ensure the aesthetics of the detection system, a first cover plate 122 is also provided on the first air inlet 121, and the first cover plate 122 may be a sheet metal part, and is provided with a plurality of grid-like gaps, and is covered on the outside of the first air inlet 121. The second air inlet 123 is used to receive the working gas required for detection. For example, for the first detection module 161, it is necessary to combine hydrogen to realize the detection of gas components. Therefore, it is necessary to provide hydrogen for the first detection module 161 when it is working. In this case, hydrogen is the working gas, which enters the detection module through the second air inlet 123 and participates in the detection of gas components. The hardware interface 124 is used to connect the detection system with external devices, such as the connection with the host computer, display screen, etc., so that the user can control the gas detection through the host computer and intuitively view the gas detection results through the display screen.

[0078] A relay group 125 and a second cover plate 126 for protecting the relay group 125 may also be provided on the first side panel 120. The second cover plate 126 may be a sheet metal part, which is covered on the outside of the relay group 125 to protect the relay group 125. The relay group 125 is used to transmit a signal to the user so that the user can judge whether the ventilation and disinfection equipment needs to be turned on according to the signal.

[0079] In addition, the present invention does not limit the position of the first air inlet 121, the second air inlet 123, the hardware interface 124 and the relay group 125 on the first side plate 120. Figure 1-2 What is described in the specification is an exemplary configuration, and can be adaptively adjusted according to actual needs.

[0080] Figure 3 A schematic diagram of the structure of the core 150 in the multi-spectral gas detection system provided in an embodiment of the present invention; Figure 3 As shown, the detection system also includes:

[0081] The movement 150 includes a first mounting frame 151 and a second mounting frame 152;

[0082] A plurality of detection modules 160 are arranged on the first mounting frame 151 and are respectively connected to the first air inlet 121, the second air inlet 123 and the exhaust port 111; the first mounting frame 151 is a layered structure; the plurality of detection modules 160 include a first detection module 161, a second detection module 162, a third detection module 163 and a fourth detection module;

[0083] Among the multiple detection modules 160, the first detection module 161 is disposed on the top of the first mounting frame 151, the second detection module 162 is disposed on the bottom of the first mounting frame 151, the third detection module 163 is disposed between the first detection module 161 and the second detection module 162, and the fourth detection module is disposed inside the second detection module 162;

[0084] A first control module 164, disposed on the second mounting frame 152, is in communication with the plurality of detection modules 160, and is used to monitor the working status of the plurality of detection modules 160;

[0085] The second control module 165 is disposed on the first mounting bracket 151 and is connected to the first control module 164 and the hardware interface 124 .

[0086] In a specific embodiment, the main structure of the movement 150 can be considered as a mounting frame, a plurality of detection modules 160 and a second control module 165 are arranged on the first mounting frame 151, and a first control module 164 is arranged on the second mounting frame 152, and the mounting frame, the control module and the detection module together constitute the movement 150. The outer side of the movement 150 is sleeved with a chassis 100, and the movement 150 and the chassis 100 are fixedly connected by screws; in the movement 150, the first mounting frame 151 can be a layered structure composed of aluminum alloy welded parts, so that a plurality of detection modules 160 are arranged on the first mounting frame 151 in a stacked state.

[0087] For multiple detection modules 160, they can include a first detection module 161, a second detection module 162, a third detection module 163 and a fourth detection module. The first detection module 161, the second detection module 162 and the third detection module 163 correspond to a first air inlet 121 and an exhaust port 111 respectively, so that the gas to be detected enters the corresponding detection module through the first air inlet 121, thereby ensuring that each detection module works independently and discharges the gas to be detected after the detection is completed; for the fourth detection module, since it is integrated inside the second detection module 162, it can share a first air inlet 121 and an exhaust port 111 with the second detection module 162.

[0088] Among them, the first detection module 161 can be a flame photometry module, which is arranged at the top of the first mounting frame 151, the second detection module 162 can be an ion migration module, which is arranged at the bottom of the first mounting frame 151, and the third detection module 163 can be a Fourier infrared module, which is arranged in the middle of the first mounting frame 151, that is, between the first detection module 161 and the second detection module 162. The fourth detection module can be composed of a chemical sensor array and integrated inside the second detection module 162; the position setting of multiple detection modules 160 on the first mounting frame 151 can be set in combination with their working characteristics. For example, since the third detection module 163 is more sensitive to external interference, it can be set at the bottom to avoid shaking caused by the weak support force on the top of the first mounting frame 151, thereby affecting the measurement result. It can be understood that the position setting of multiple detection modules 160 on the first mounting frame 151 in the present invention is an exemplary scheme, and adaptive changes can be made in actual operation. By integrating multiple detection modules 160 in a multi-spectral gas detection system and each detection module is independent, the limitations and defects of each detection module itself can be compensated, thereby improving the comprehensiveness and accuracy of gas detection.

[0089] In addition, since the first detection module 161 needs to be combined with hydrogen during the detection process, the first detection module 161 is also connected to the second air inlet 123 so that the working gas can be input into the first detection module 161; and, since the third detection module 163 needs to evacuate the internal unknown component gas before working, the third detection module 163 is also connected to the second air inlet 123 so that the working gas, such as nitrogen, can be input into the third detection module 163; that is, in the multi-spectral gas detection system, the number of second air inlets 123 can be multiple; there is at least one second air inlet 123 corresponding to the first detection module 161, and one second air inlet 123 corresponding to the third detection module 163.

[0090] As for the control module, the detection system may be provided with two control modules, namely, a first control module 164 and a second control module 165; the first control module 164 is a main control board, which is fixed to the second mounting frame 152 by screws, such as Figure 3 As shown, the second mounting frame 152 can be fixed on the second detection module 162 by screws, and can be connected to multiple detection modules 160 for communication, so as to detect the working status of multiple detection modules 160, so as to timely judge and discover the faults inside the detection modules; the second control module 165 can be an industrial computer, or it can be set on the second detection module 162, and communicate with the first control module 164 to receive the working status information sent by the first control module 164, and output alarm information when the working status information indicates that the detection module has a fault or other problems. At the same time, the second control module 165 can also be connected to the host computer for communication, so that the gas detection data output by the detection module can be transmitted to the host computer.

[0091] Figure 4 A gas path schematic diagram corresponding to a multi-spectral gas detection system provided in an embodiment of the present invention, such as Figure 4 As shown, when the detection system is working, the gas to be detected is transmitted to the multiple detection devices through the multiple chassis air inlets, and the gas to be detected is discharged from the detection system to the external environment through the multiple chassis air outlets. Each detection module is provided with an air inlet and an air outlet corresponding to the chassis air inlet and the chassis air outlet, respectively, to realize the input and output of the gas to be detected. In addition, since the flame photometry detection module also needs to use hydrogen during operation, the flame photometry detection module is also provided with a corresponding hydrogen inlet to receive the hydrogen input through the chassis air inlet; since the Fourier infrared detection module needs to use nitrogen to exhaust the gas of unknown components in the device before working, the Fourier infrared detection module is also provided with a corresponding nitrogen inlet and a nitrogen outlet to receive and discharge the nitrogen input through the chassis air inlet.

[0092] In addition, the detection system further includes a host computer, which is connected to the second control module 165 via the hardware interface 124, and the host computer is used to execute the gas detection method. Figure 5 A system block diagram corresponding to a multi-spectral gas detection system provided in an embodiment of the present invention is shown below in conjunction with Figure 5 Describe the settings of the host computer.

[0093] like Figure 5 As shown, it can be considered that the multiple detection modules 160 are chemical monitoring alarm modules, the integrated acquisition control module is the first control module 164, and the gas acquisition and processing module is the first air inlet 121 and the second air inlet 123 on the chassis 100. Since the gas acquisition and processing module can also perform pre-processing such as dust removal and dehumidification on the collected gas, in another specific embodiment, it can also be considered that the multi-spectrum gas detection system is also provided with a module for pre-processing and detecting the gas to be detected, and is combined with the first air inlet 121 and the second air inlet 123 to jointly engineer the gas acquisition and processing module.

[0094] The host computer can be connected to the second detection module 162 (industrial computer) through the hardware interface 124, that is, the network port shown in the figure, to realize the transmission of gas detection data and the control of the gas detection method by the host computer. At the same time, the multi-spectral :0 gas detection system can also be connected to the second detection module 162 (industrial computer) through the hardware interface 124, such as Figure 5 The USB and other external cameras, display screens and other settings can be used to realize real-time monitoring of the surrounding environment corresponding to the gas to be detected, and the target recognition results corresponding to the gas to be detected can be intuitively understood through the display screen.

[0095] The following will be combined Figure 6-Figure 11 Describe how the host computer controls the multi-spectrum gas detection system to execute the gas detection method. Figure 6 A schematic diagram of a flow chart corresponding to a multi-spectral gas detection method provided in an embodiment of the present invention, the execution subject may be a host computer in a multi-spectral gas detection system, or any other terminal or mobile device capable of executing the multi-spectral gas detection method. Figure 6 As shown, a multi-spectral gas detection method comprises:

[0096] Step S601: In response to a user trigger operation, a gas detection instruction is generated; the gas detection instruction is used to trigger each gas detection module to perform gas detection on a gas to be detected;

[0097] In a specific embodiment, the user can implement the trigger operation by turning on the control switch 113 on the chassis, or after turning on the control switch 113, implement the trigger operation through interaction with the host computer; when the user's trigger operation is received and it is considered necessary to start gas detection, a gas detection instruction is generated. The gas detection instruction can be sent to each detection module in the detection system through the host computer and the second control module, so that each detection module starts working after receiving the gas detection instruction.

[0098] In another specific embodiment, before generating the gas detection instruction, the method includes:

[0099] In response to the user triggering operation, generating a module verification instruction;

[0100] Based on the module verification instruction, a working state verification is performed on each gas detection module to obtain a module verification result;

[0101] When the module verification result indicates that each of the gas detection modules is in a normal working state, the gas detection instruction is generated.

[0102] If the module verification result indicates that at least one gas detection module among the plurality of gas detection modules is in an abnormal working state, generating module abnormality information corresponding to the at least one gas detection module based on the module verification result;

[0103] Displays the module exception information.

[0104] Specifically, in order to ensure the reliability of the detection system and the timeliness of fault discovery and maintenance of the detection system, a module verification instruction can be generated after each user trigger operation is received. The module verification instruction is used to control each detection module to verify its own working status to determine whether the detection module can perform gas detection normally.

[0105] The module verification result may include the working status corresponding to each gas detection module. When all the gas detection modules correspond to the normal working status, it can be determined that the detection system is capable of detecting the gas to be detected, and a gas detection instruction is generated; if the module verification result indicates that among multiple gas detection modules, there is at least one gas detection module with an abnormal working status, module abnormality information of the corresponding abnormal detection module is generated according to the module verification result, and the module abnormality information can be displayed through an external display screen, so that the user can check the abnormality in time; different colors of indicator lights on the chassis can also be set to correspond to different detection module abnormalities, so that the user can intuitively feel the working status of the detection module through the color changes of the indicator lights.

[0106] Step S602: receiving a plurality of gas detection data corresponding to the gas to be detected; each gas detection data includes a gas detection parameter;

[0107] In a specific embodiment, after the host computer generates a gas detection instruction, it sends the gas detection instruction to multiple detection modules, so that the multiple detection modules detect the gas to be detected, and sends the gas detection data including gas detection parameters corresponding to each detection module to the host computer.

[0108] Specifically, for the Fourier infrared detection module, the detection principle is: when infrared light with a continuous wavelength irradiates the molecules of the substance being tested, infrared light with the same inherent vibration frequency of the molecule is absorbed, and an infrared absorption spectrum with wave number as the horizontal coordinate and absorbance as the vertical coordinate is obtained. Different substances absorb infrared light differently, which can be manifested as different wave numbers of characteristic absorption peaks. Fourier transform infrared spectroscopy converts the light emitted by the infrared light source into interference light through a Michelson interferometer, and then irradiates the gas sample with the interference light to obtain an infrared interference pattern, which is then processed by a computer system through Fourier transform to obtain an infrared absorption spectrum. By comparing the infrared absorption spectrum of the gas sample with the infrared absorption spectrum of the standard substance in the standard spectrum library, the sample can be qualitatively analyzed. Under certain conditions, the characteristic absorption peak intensity of the target compound in the infrared absorption spectrum and its concentration follow the Lambert-Beer law, and the target compound can be quantitatively analyzed based on the absorption peak intensity.

[0109] For the ion migration module, the detection principle is to separate and measure ions based on the difference in ion drift time. It is a normal pressure analytical chemistry method that detects and identifies different types of substances based on the mobility of gas-phase ions in a weak electric field. After the sample gas is heated and vaporized, it is brought into the ionization zone by the carrier gas. Under the action of the ion source, a series of ionization reactions and ion-molecule reactions occur between the carrier gas molecules and the sample molecules to form various product ions. Under the action of the electric field, these product ions enter the migration zone through the periodically opened ion gate. Different ion groups collide with the detector at different migration rates in the electric field, and the different ion groups are distinguished and identified due to the different arrival times.

[0110] For the chemical sensor array module, the detection principle is as follows: the chemical sensor array detection module intends to use a variety of sensors such as PID, EC, MOS, etc. to form a sensor array. Each sensor has different response levels to different types of gases. According to the different response curves of each sensor in the array, the type of gas can be determined by comparing with the existing database. The photoionization gas sensor (PID) uses an ultraviolet (UV) light source to ionize organic matter into positive and negative ions detected by the detector. The detector measures the charge of the ionized gas and converts it into a current signal. By detecting the current size, the probability concentration of toxic and harmful gases can be obtained. The electrochemical sensor (EC) realizes the identification of substances and the probability concentration determination by generating an electrochemical reaction with a specific gas to be measured and generating a current signal proportional to the gas concentration. The metal oxide semiconductor sensor (MOS) detects specific gases by using the physical properties of semiconductors such as conductivity caused by the contact between semiconductor gas sensors and gases.

[0111] For the flame photometry module, the detection principle is: the flame is used for excitation, so that the measured element emits a characteristic spectrum line, and the detector is used to measure the intensity of the characteristic spectrum line of the measured element to perform element determination and analysis. After the sample is sent into the flame for combustion, the heat energy of the flame is used to atomize the sample elements and excite the outer electrons of the atoms to a high energy state (excited state). When the atoms return from a high energy level to a low energy level, they release excess energy and produce a spectrum line with a specific wavelength, thereby determining the chemical composition of the sample.

[0112] In another specific embodiment, before receiving a plurality of gas detection data, the method includes:

[0113] Acquire preset detection data corresponding to different gas types; the preset detection data includes a preset gas type, a preset temperature, and a preset detection parameter corresponding to the preset temperature;

[0114] Performing data fitting on the preset temperature and the preset detection parameter corresponding to each preset gas type respectively to generate preset standard data corresponding to each preset gas type;

[0115] The preset gas database is constructed based on the preset standard data, and the preset gas database is stored.

[0116] Specifically, different gas types are known gas types, which are respectively input into each detection module for gas detection. The obtained gas detection data is the preset detection data. Since the gas type is known and the gas detection data may be affected by temperature changes, the preset detection data may include the preset gas type, preset temperature, and the preset detection parameters corresponding to the gas at the preset temperature.

[0117] The preset temperature and preset detection parameters corresponding to each preset gas type can be regarded as a group of data, and each group of data can be fitted to obtain preset standard data corresponding to the preset gas type; a preset gas database can be constructed based on the preset standard data. For example, it can be considered that one preset gas type can correspond to multiple preset standard data, wherein the multiple preset standard data respectively correspond to the preset standard data obtained after multiple different detection modules detect the preset gas type. The multiple preset standard data corresponding to the multiple preset gas types are integrated to construct and store the preset gas database. The preset gas database can be used as a judgment standard in the gas detection process.

[0118] Step S603: Based on the preset gas database and the gas detection parameters, the gas to be detected is identified to obtain multiple gas identification results;

[0119] Specifically, the preset gas database can be used to match the gas detection parameters corresponding to each detection module respectively, and the preset gas type corresponding to the gas detection parameters matching the preset standard data is determined, and the gas identification result of the gas to be detected is considered to be the preset gas type.

[0120] Step S604: performing data correction on the multiple gas identification results to obtain a target identification result corresponding to the gas to be detected.

[0121] In a specific embodiment, the data correction of the multiple gas identification results to obtain the target identification result corresponding to the gas to be detected includes:

[0122] Determine any one of the plurality of gas identification results as a determination reference value;

[0123] Performing data comparison based on the reference value and the plurality of gas identification results to obtain a data comparison result; the data comparison result includes data missing information and data error information;

[0124] Based on the data missing information and the data error information, data correction is performed on the multiple gas identification results to obtain the target identification result.

[0125] Since multiple detection modules in the detection system are independent of each other, and in one detection process, multiple detection modules independently verify the gas of the same composition, theoretically, the gas identification results output by each detection module should be the same; therefore, multiple gas identification results corresponding to multiple detection modules can be used to verify each other, thereby improving the accuracy and comprehensiveness of gas identification.

[0126] Specifically, first determine any one of the multiple gas identification results as the reference value, and compare the remaining gas identification results with the reference value to obtain the data comparison result, which includes data missing information and data error information; for example, for multiple detection modules, their detection capabilities, that is, the types and accuracy of gas component identification, are different, so the missing information in the gas identification result can be corrected based on the reference value to obtain a more comprehensive gas identification result. In addition, since there are differences in the identification accuracy of multiple detection modules, it is possible to determine whether there are identification errors in the remaining gas identification results based on the reference value, and correct the gas identification results based on the error information to obtain the target identification result.

[0127] Each gas identification result corresponds to a detection module information;

[0128] After obtaining the target recognition result corresponding to the gas to be detected, the method includes:

[0129] Displaying a result viewing interface; the result viewing interface at least includes the detection module information corresponding to each gas identification result;

[0130] In response to a user viewing request, jump to the gas identification result corresponding to the detection module information; the gas identification result includes a gas identification map and gas identification parameters.

[0131] In a specific embodiment, after the target identification result is obtained by performing gas identification on the gas to be detected, the target identification result can be viewed through the display interface, such as Figure 7 As shown, the result viewing interface includes multiple interactive buttons and a result display window. The interactive buttons may include "Fourier infrared", "ion migration module", "chemical sensor" and "flame photometry". The result display window may include video information and device status. The video information is the external environmental information during the gas detection process obtained through an external camera.

[0132] User viewing request can be issued by clicking any interactive button in the result display interface, such as Figure 8 As shown, when the user clicks the "Fourier Infrared" button, it jumps to the gas detection data corresponding to the Fourier Infrared detection module. The gas detection data may include a real-time spectrum, and the state parameters may include identification of substances, i.e., gas type information, wave number settings, and module status information.

[0133] like Fig. 9 As shown in the figure, for the "Ion Migration Module", the positive and negative spectra of ion migration can be displayed, and the parameters on the right include temperature, air pressure, humidity, alarm substances, module status and other information; Fig.10As shown in the figure, for the "chemical sensor array module", each sensor generates a time-value curve, and the right side displays the real-time value, offset, alarm substance, module status and other information of each sensor; Fig.11 As shown, for the "flame photometry module", the flame photometry spectrum is displayed in real time, and the parameters on the right can include information such as temperature, air pressure, humidity, alarm substances, module status, etc.

When the self-check is successful, multiple detection modules are controlled to perform gas detection, and the results are sent to the host computer for processing to output the target recognition result; when the self-check fails, the fault information is sent to the host computer, and the fault information is displayed on the display screen.

[0138] It can be seen from the embodiments provided by the present invention that in the present invention, by integrating multiple detection modules of different types in a multi-spectral gas detection system, and each detection module is independently arranged, multiple gas identification results are obtained after each detection module performs gas detection on the gas to be detected, and self-verification is performed based on the multiple gas identification results, and the gas identification result is corrected according to the verification result to obtain the target identification result, thereby improving the accuracy and reliability of the gas detection process; in addition, since each detection module is independent of each other, combining multiple detection modules can make up for the incomplete gas component identification caused by the detection module's own limitations, thereby improving the comprehensiveness of the gas identification process and results; at the same time, the multi-spectral gas detection system is externally connected to a display screen, and the gas detection results corresponding to different detection modules are intuitively displayed through the display screen, thereby improving the convenience and intuitiveness of users in viewing the detection results.
