Description

Technical Field

[0001] This utility model relates to the field of safety detection technology, and in particular to a desktop multidimensional hazardous liquid detector. Background Technology

[0002] In the current field of public safety, the detection and identification of liquid substances is a crucial task. With the increasing frequency of security incidents such as terrorist attacks and the illegal possession of dangerous goods, the ability to quickly and accurately detect and identify potential hazards in liquid substances has become an urgent problem to be solved. Traditional liquid detection methods, such as manual observation and chemical reagent testing, are not only inefficient but also carry the risk of misjudgment and missed detection, failing to meet the high requirements of modern security detection.

[0003] To address this challenge, some liquid detectors based on advanced technologies have gradually emerged in the market. However, these instruments often have limited functionality, capable of only performing simple liquid composition analysis and unable to provide crucial information such as the liquid's source and intended use, thus restricting their practical application in safety testing. Furthermore, while some instruments possess barcode scanning capabilities, these are often independent of the detection module, failing to achieve real-time information correlation and feedback, resulting in cumbersome and inefficient testing processes.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0056] The following is combined Figures 1-3 This invention describes a benchtop multidimensional hazardous liquid detector provided in an embodiment of the present invention.

[0057] In some embodiments, such as Figures 1 to 3 As shown, the desktop multidimensional hazardous liquid detector includes: a barcode scanning module 1, a detection module 2, a control module 4, and a printing module 3. The barcode scanning module 1 scans the container to generate barcode information; the detection module 2 detects the substance to be tested in the container to generate a detection signal; the control module 4 is communicatively connected to a server and electrically connected to the barcode scanning module 1 and the detection module 2, receiving the barcode information and detection signal, and sending the barcode information to the server to receive the item information fed back by the server based on the barcode information. Simultaneously, it determines the category of the substance to be tested based on the detection signal, including hazardous samples and safe samples; the printing module 3 is electrically connected to the control module 4 and / or the control module 4, and prints a label including the item information and / or category based on the signal fed back by the control module 4.

[0058] Specifically, the scanning module 1 is used to scan barcodes or QR codes on the container to generate scanning information. The scanning information typically includes basic information such as the container's unique identifier, production date, and expiration date.

[0059] Detection module 2 uses chemical, physical, or biological sensing technologies to detect the analyte in the container. The detection signal is an electrical signal generated based on the characteristics of the analyte (such as composition, density, refractive index, etc.).

[0060] Control module 4 can be an Android device or other host computer, responsible for data processing and communication. Control module 4 can send the scanned information to the server, which returns item information (such as substance name, purpose, safety level, etc.) based on information in the database. Control module 4 analyzes the detection signal according to a preset algorithm or model to determine the category (hazardous sample or safe sample) of the substance being tested.

[0061] Printing module 3, following instructions from control module 4, prints and generates labels containing item information and / or its category. The label content can be adjusted as needed, and may include, for example, the substance name, safety level, test results (hazardous / safe), and test date.

[0062] During the detection process using this desktop multidimensional hazardous liquid detector, the user places the container to be tested under the barcode scanning module 1. The scanning module 1 scans the barcode or QR code on the container and generates scan information. After obtaining the scan information, the control module 4 sends the scan information to the server. The server returns the item information to the control module 4 based on the scan information.

[0063] Simultaneously, the detection module 2 detects the substance to be tested and generates a detection signal. After receiving the detection signal, the control module 4 analyzes it and determines the category (hazardous sample or safe sample) of the substance to be tested based on the detection signal. After determining the category and item information, the control module 4 sends the item information and / or category to the printing module 3, which prints a label containing this information.

[0064] This utility model provides a desktop multi-dimensional hazardous liquid detector that integrates a barcode scanning module 1, a detection module 2, a control module 4, and a printing module 3 to achieve efficient and accurate detection and identification of liquid substances. This detector can not only quickly obtain liquid composition information but also acquire additional information such as the liquid's source and purpose through barcode scanning, thus enabling a comprehensive assessment of the liquid substance. Simultaneously, through the communication connection between the control module 4 and the server, the detector can receive feedback information from the server in real time. Based on the feedback signal from the control module 4, the printing module 3 prints a label containing item information and / or its category, facilitating subsequent safety management and traceability, further improving the accuracy and reliability of the detection.

[0065] In some embodiments, such as Figures 1 to 3As shown, the desktop multidimensional hazardous liquid detector includes a main body 8 and an interaction module 5. The interaction module 5, barcode scanning module 1, detection module 2, control module 4, and printing module 3 are all mounted on the main body 8. The interaction module 5 is electrically connected to the control module 4 and is used to transmit control signals to the control module 4 and / or output item information and / or its category.

[0066] Specifically, the body 8 includes an outer shell 81 and a base plate 82. The outer shell 81 and the base plate 82 are joined together to form a cavity for housing the barcode scanning module 1, the detection module 2, the control module 4, and the printing module 3. Some structures of the barcode scanning module 1, the detection module 2, the control module 4, and the printing module 3 are located within the cavity, while others are directly mounted on the outer shell 81. The design of the cavity fully considers the operating space requirements of each module, ensuring that each module achieves optimal performance during normal operation. The outer shell 81 is made of high-strength material, possessing excellent wear resistance, corrosion resistance, and impact resistance, effectively protecting the internal modules from external environmental influences. The base plate 82 is made of lightweight and robust material to withstand various torques and vibrations generated during equipment operation.

[0067] like Figure 1 and Figure 2 As shown, the interaction module 5 includes a display screen 51 and buttons 52. The display screen 51 is electrically connected to the control module 4 and is used to display item information and / or its category; the buttons 52 are electrically connected to the control module 4 and are used to transmit control signals to the control module 4 based on input.

[0068] In this embodiment, the display screen 51 is used to display various information, including but not limited to item information (such as substance name, purpose, safety level, etc.) and its category (hazardous sample or safe sample). The display screen 51 is electrically connected to receive data and information sent by the control module 4 and presents it to the user in a visual manner. The display screen 51 may employ technologies such as liquid crystal display (LCD) or organic light-emitting diode display (OLED) to provide a clear and easy-to-read display effect.

[0069] Button 52 serves as a user input device, used to transmit control signals to the control module 4 based on user operations. The button is also electrically connected; pressing or releasing button 52 triggers a corresponding electrical signal, which is received and interpreted by the control module 4 as a specific control command. Depending on the needs, button 52 may include function keys (such as start detection, stop detection, print label, etc.) and numeric keys (for inputting specific information or selecting options). Furthermore, button 52 is equipped with tactile feedback (such as a "click" sound or vibration when button 52 is pressed) or visual feedback (such as corresponding prompts on the display screen 51) to enhance the user experience.

[0070] Depending on the needs, the interactive module 5 may also include an alarm light and a loudspeaker 53, etc.

[0071] The alarm light is used to issue a visual alert under specific circumstances to attract the user's attention. The alarm light is connected to the control module 4, receives alarm signals sent by the control module 4, and adjusts the lighting effect according to the type and intensity of the signal. For example, when the test result indicates that the substance being tested is a hazardous sample, the alarm light can flash red or emit other conspicuous light signals to warn the user. The alarm light can also issue corresponding alarms when equipment malfunctions, has insufficient power, or requires maintenance.

[0072] The loudspeaker 53 is connected to the control module 4, receives audio signals sent by the control module 4, and converts them into audible sound. The loudspeaker 53 is used to issue sound alarms or play voice prompts to provide additional information or instructions. For example, when a hazardous sample is detected, the loudspeaker 53 can play a preset alarm sound or voice prompt, such as "Hazardous substance detected, please handle with care." The loudspeaker 53 can also issue sound prompts at critical moments such as equipment startup, completion of testing, and label printing to enhance user perception and experience.

[0073] In some embodiments, such as Figure 1 and Figure 2 As shown, the benchtop multidimensional hazardous liquid detector also includes an interface module 6, which is electrically connected to the control module 4, enabling the control module 4 to electrically connect to external devices via the interface module 6. The interface module 6 acts as a bridge between the control module 4 and external devices, allowing the control module 4 to communicate data and transmit power to external devices. For example, the interface module 6 is used for upgrading the system software of the control module 4 and exporting stored information from the control module 4.

[0074] Specifically, interface module 6 includes an audio interface, a network interface, and a USB interface. The audio interface is electrically connected to control module 4; the network interface is electrically connected to control module 4; and the USB interface is electrically connected to control module 4.

[0075] The audio interface is used to connect external audio devices, such as headphones, speakers, or microphones. The audio interface enables the transmission of audio signals between the control module 4 and the external audio devices. When the detector needs to play sound prompts or alarms, it can output through the connected speaker. When it is necessary to record voice information or conduct voice communication, the connected microphone can be used. Users can listen to the detector's prompts through headphones, avoiding missing important information in noisy environments.

[0076] The network interface is used to connect external networked devices, enabling communication between the detector and the network. The network interface is electrically connected to control module 4, supporting wired or wireless (such as Wi-Fi or Bluetooth) network connections. Through the network interface, the desktop multi-dimensional hazardous liquid detector can upload detection results to a cloud server in real time, enabling remote monitoring and data management. The detector can receive remote commands or updates via the network, enabling remote control and software upgrades. In scenarios where multiple devices work collaboratively, the network interface allows the detector to communicate and exchange data with other devices.

[0077] The USB interface is used to connect external electronic devices such as USB flash drives, mice, and keyboards. The USB interface is electrically connected to control module 4 and supports data transfer standards of USB 2.0, USB 3.0, or higher. Users can export test results to a USB flash drive via the USB interface for offline analysis and archiving. When large amounts of data need to be entered or complex operations are required, the connected keyboard and mouse can be used.

[0078] For some interfaces (such as USB interfaces), in addition to data transmission, power transmission can also be provided, allowing external devices to be charged or powered through the desktop multidimensional hazardous liquid detector.

[0079] In some embodiments, such as Figures 1 to 3 As shown, the desktop multidimensional hazardous liquid detector also includes a power supply module, which is electrically connected to the barcode scanning module 1, the detection module 2, the control module 4, and the printing module 3 to supply power to the barcode scanning module 1, the detection module 2, the control module 4, and the printing module 3.

[0080] The power supply module is responsible for providing stable and reliable power to all modules of the detector, ensuring their normal operation. The power supply module can be equipped with an energy management system to monitor battery level, charging status, and power consumption, ensuring continuous operation when needed. The power supply module is connected to the barcode scanning module 1, detection module 2, control module 4, and printing module 3 via wires or conductive traces on a circuit board, forming a complete power supply network.

[0081] The power supply module may contain one or more rechargeable batteries (such as lithium-ion batteries) to provide power when the device is moving or when there is no external power source. When the device is in a stationary location or needs to operate for extended periods, the power supply module can be charged or powered by an external power source (such as an AC power adapter).

[0082] In addition, such as Figures 1 to 3As shown, the desktop multidimensional hazardous liquid detector also includes a power conversion module. One end of the power conversion module is electrically connected to the power supply module, and the other end is electrically connected to the barcode scanning module 1, the detection module 2, the control module 4, and the printing module 3. It is used to convert the electrical energy provided by the power supply module into the working voltage and / or current required by the barcode scanning module 1, the detection module 2, the control module 4, and the printing module 3.

[0083] In this embodiment, the main function of the power conversion module is to convert the raw electrical energy (DC or AC, but the voltage and current are not suitable for all modules) provided by the power supply module into the working voltage and / or current required by the barcode scanning module 1, the detection module 2, the control module 4, and the printing module 3.

[0084] In addition to its conversion function, the power conversion module is also responsible for distributing the converted electrical energy to each module, ensuring that they can operate simultaneously and stably. To prevent damage to the equipment from abnormal conditions such as overvoltage, overcurrent, and short circuits, the power conversion module usually also includes protection circuits that can quickly cut off the power supply or adjust the output when an abnormality is detected.

[0085] When voltage conversion is required, the power conversion module uses components such as transformers and voltage regulators to increase or decrease the input voltage to meet the operating needs of different modules. When current adjustment is required, the power conversion module can control the output current by adjusting components such as resistors and inductors at the output terminal, ensuring that each module operates within a safe operating range.

[0086] Based on the above embodiments, in some embodiments, such as Figures 1 to 3 As shown, the desktop multidimensional hazardous liquid detector also includes a Raman detection module 7. The Raman detection module 7 is electrically connected to the printing module 3 and the control module 4. When the control module 4 reports that the substance to be tested is a hazardous material, the Raman detection module 7 performs laser detection on the substance to be tested to help the control module 4 determine the specific substance being tested. The printing module 3 is used to print a label containing the specific substance based on the feedback from the control module 4.

[0087] Specifically, the Raman detection module 7 utilizes laser technology for non-contact detection of the test substance. When the control module 4 indicates that the test substance is hazardous, the Raman detection module 7 emits a laser beam to irradiate the test substance. The interaction between the laser and the test substance produces scattered light. By collecting and analyzing the spectral characteristics of this scattered light, the Raman detection module 7 can identify the specific chemical composition of the test substance. The Raman detection module 7 then feeds back the analyzed spectral data to the control module 4, which further determines the specific substance type based on this data.

[0088] In actual operation, the equipment first performs preliminary screening of the substance to be tested using other detection methods (such as X-rays, millimeter waves, etc.). If it is suspected to be a hazardous material, Raman detection is triggered. After receiving the instruction from the control module 4, the Raman detection module 7 emits a laser beam to irradiate the substance to be tested. The Raman detection module 7 collects and analyzes the spectral characteristics of the scattered light. The analysis results are fed back to the control module 4, which determines the specific type of the substance to be tested based on the spectral data. The control module 4 sends the determined specific substance information to the printing module 3, which prints a label containing the specific substance based on this information.

[0089] In some embodiments, such as Figures 1 to 3 As shown, the detection module 2 has two modules: a metal container detection module 21 and a non-metal container detection module 22. The metal container detection module 21 heats and detects the substance to be tested in a metal container to generate a first detection signal. The non-metal container detection module 22 performs dielectric detection on the substance to be tested in a non-metal container to generate a second detection signal. The control module 4 is electrically connected to the metal container detection module 21 and the non-metal container detection module 22. It receives the first or second detection signal and determines the category of the substance to be tested based on the first or second detection signal. The category includes hazardous materials (e.g., flammable and explosive substances). The Raman detection module 7 is electrically connected to the control module 4. When the control module 4 reports that the substance to be tested is hazardous, the Raman detection module 7 performs laser detection on the substance to be tested to assist the control module 4 in determining the specific substance being tested.

[0090] During the testing process using this desktop multidimensional hazardous liquid detector, when the container to be tested is a metal container, the metal container detection module 21 heats and detects the substance to be tested in the metal container to generate a first detection signal, which is then sent to the control module 4. After receiving the first detection signal, the control module 4 can determine the category of the substance to be tested based on the first detection signal. For example, it can determine whether the substance to be tested is a hazardous or non-hazardous substance, and determine its major category information, such as fuel oil or soda ash.

[0091] When the container to be tested is a non-metallic container, the non-metallic container detection module 22 is used to heat and detect the substance to be tested in the non-metallic container to generate a second detection signal, and the second detection signal is sent to the control module 4. After receiving the second detection signal, the control module 4 can determine the category of the substance to be tested based on the second detection signal.

[0092] Since substances of the same category have similar physical properties and dielectric parameters, the measurement principles used by the metal container detection module 21 and the non-metal container detection module 22 can only determine their category. To specifically identify the substances within hazardous materials, when the container to be tested contains hazardous materials, the Raman detection module 7 can be used for laser detection. The Raman detection module 7 can transmit the detected signal to the control module 4, which, in conjunction with the control module 4, performs specific category identification of the hazardous materials to determine the specific substances contained within.

[0093] In other words, when using the desktop multidimensional hazardous liquid detector, you can first use the metal container detection module 21 or the non-metal container detection module 22 to perform negative detection, identify the category of the substance to be tested, and determine whether it contains hazardous materials. Then, the Raman detection module 7 can be used to further identify the specific hazardous materials.

[0094] For example, when the metal container detection module 21 or the non-metal container detection module 22 detects that the container under test contains fuel-like substances, the Raman detection module 7 can output that the fuel-like substances are specifically gasoline, kerosene, or diesel. When the metal container detection module 21 or the non-metal container detection module 22 detects that the container under test contains soda ash-like substances, the Raman detection module 7 can output that the soda ash-like substances are specifically potassium hydroxide or sodium hydroxide.

[0095] Furthermore, the Raman detection module 7 can identify and analyze substances contained in the database, including various flammable and explosive liquid hazardous chemicals such as organic and inorganic hazardous chemicals. Moreover, the Raman detection module 7 can perform chemical analysis and identification of pure liquid and solid hazardous chemicals in transparent or brown transparent containers (plastic, paper, glass, and plastic bags, etc.), and can also achieve rapid and accurate identification and proportion analysis of mixtures. However, the Raman detection module 7 cannot detect liquids or powders in thin-walled metal containers. If the container to be tested does not meet the measurement requirements of the Raman detection module 7, for example, if the container is metal, the substance inside needs to be poured into a specific volumetric flask, such as a non-metallic volumetric flask, and then further detected using the Raman detection module 7 to determine the specific substance.

[0096] The desktop multidimensional hazardous liquid detector provided by this utility model detects the substance to be tested through the metal container detection module 21 and the non-metal container detection module 22, and works with the control module 4 to determine the category of the substance to be tested. When the substance to be tested is a hazardous material, the Raman detection module 7 works with the control module 4 to determine the specific substance of the substance to be tested. It can not only determine whether the substance to be tested is hazardous, but also determine the category of the substance to be tested. Furthermore, it can analyze and identify the specific chemical name of the hazardous substance to be tested, thereby improving the accuracy and efficiency of hazardous material detection.

[0097] like Figures 2 to 4 As shown, in one embodiment of this utility model, as Figures 2 to 4 As shown, the metal container detection module 21 includes: a metal container carrier 211, a metal detection element, and a heating detection assembly 212. The first detection signal generated by the metal container detection module 21 in detecting the substance to be tested in the metal container includes a temperature change signal.

[0098] The metal container carrier 211 can be an inclined metal container detection groove used to carry the container to be tested. A metal detection element is disposed on one side of the metal container carrier 211 and is electrically connected to the control module 4. The metal detection element is used to detect whether the container to be tested is a metal container and transmits the detection result to the control module 4. The heating detection assembly 212 is electrically connected to the control module 4. When the control module 4 provides feedback that the container to be tested is a metal container, the heating detection assembly 212 heats the substance to be tested in the non-metallic container to generate a temperature change signal. The control module 4 is also used to receive the temperature change signal and determine the category of the substance to be tested based on the temperature change signal.

[0099] Specifically, when a container to be tested is placed inside the metal container carrier 211, the metal detection element detects whether the container to be tested has a metal outer shell 81. When it is detected as a metal container, the control module 4 controls the heating detection component 212 to perform heating detection based on the detection result, thereby generating a temperature change signal of the metal container and the substance to be tested within it. Since metal containers have the characteristic of rapid heat transfer, and different substances to be tested have different specific heat capacities, the category of the substance to be tested can be determined by detecting the temperature change after heating within the metal container.

[0100] Furthermore, such as Figures 4 to 6 As shown, the metal container detection module 21 also includes a metal detection light barrier 213. The metal detection light barrier 213 is disposed on one side of the metal container carrier 211. The metal detection light barrier 213 is electrically connected to the control module 4. The metal detection light barrier 213 is used to detect whether a container to be tested is placed on the metal container carrier 211, so as to generate a metal container placement signal and transmit it to the control module 4.

[0101] Generally, there are two metal detection light barriers 213. The two metal detection light barriers 213 are set on the two sides of the metal container carrier 211 symmetrically. One metal detection light barrier 213 emits a signal towards the other metal detection light barrier 213. When the container to be tested is located between the two, the container to be tested blocks the signal, and it can be determined that the container to be tested is located on the metal container carrier 211.

[0102] Alternatively, a weight detection component can be used. This component is positioned below the metal container support 211 and electrically connected to the control module 4. It measures the weight signal generated by the container under test and transmits the signal to the control module 4. This allows the control system to monitor the position and weight of the container in real time, ensuring the accuracy of the detection process.

[0103] In some embodiments, such as Figures 3 to 5 As shown, the heating detection assembly 212 includes a heating element 2121, a temperature detection element, and a first control board 2122. The heating element 2121 is mounted on the metal container support 211 and electrically connected to the control module 4, used to heat the substance to be tested according to the control module 4. The temperature detection element is mounted on the metal container support 211 and electrically connected to the control module 4. The first control board 2122 is electrically connected to the heating element 2121, the temperature detection element, and the control module 4. When it receives feedback from the control module 4 that the container to be tested is a metal container and located on the metal container support 211, it controls the heating element 2121 to heat the metal container, monitors the temperature change of the metal container through the temperature detection element, generates a temperature change signal, and transmits it to the control module 4 so that the control module 4 can determine the category of the substance to be tested.

[0104] In this embodiment, the heating element 2121 can be interconnected with a temperature sensing element so that the heating temperature of the heating element 2121 can be determined in real time through the temperature sensing element. The temperature sensing element can be a thermocouple, which is used to monitor the temperature of the heating element 2121 and also to detect the temperature of the container under test.

[0105] When the container to be tested is placed inside the metal container carrier 211, the metal detection light barrier 213 is triggered. The metal detection element then detects whether the container to be tested has a metal outer shell 81. If it is detected as a metal container, the control module 4, based on the detection result, controls the heating element 2121 to heat the metal container for a first preset time via the first control board 2122, and then stops heating. Afterwards, the first control board 2122 controls the temperature detection element to monitor the temperature change after a second preset time. Because metal containers have the characteristic of rapid heat transfer, and different substances to be tested have different specific heat capacities, the category of the substance to be tested can be determined by detecting the temperature change after heating within the metal container.

[0106] In one specific embodiment, the heating element 2121 can be a heating resistance wire, and the temperature sensing element can be a receiving resistance wire. The heating process of the liquid in the container under test by the heating resistance wire and the temperature rise received by the receiving resistance wire both rely primarily on heat conduction; therefore, the effectiveness of heat conduction becomes a crucial factor affecting detection accuracy. Furthermore, in practical applications, the temperatures that the heating and receiving resistance wires can withstand and their contact area with the container under test have a significant impact on the detection. To address this, a heating film can be added. This heating film can automatically and tightly adhere to the shape of the container under test, maximizing the contact area between the heating and receiving resistance wires and the container. This heating film heats up quickly, has a small temperature transmission error, is less prone to overheating damage, and thus accelerates detection speed, improves detection accuracy, and extends service life.

[0107] Based on the above embodiments, in one example, such as Figure 4 and Figure 6 As shown, the non-metallic container detection module 22 includes a non-metallic container carrier 221 and a microwave detection component 223. The non-metallic container carrier 221 can be an inclined non-metallic container detection slot used to carry the container to be tested; the microwave detection component 223 is electrically connected to the control module 4. The second detection signal includes a microwave detection signal.

[0108] During operation, when a non-metallic container is placed inside the non-metallic container carrier 221, the microwave detection component 223 performs microwave detection on the substance to be tested in the non-metallic container to generate a microwave detection signal; the control module 4 receives the microwave detection signal and determines the category of the substance to be tested based on the microwave detection signal.

[0109] It should be noted that the microwave detection component 223 detects substances within non-metallic containers based on the microwave free-space reflection theory. When microwaves encounter substances with different dielectric constants during transmission, the substance's ability to absorb microwaves is proportional to its dielectric constant. The magnitude of the reflected microwave energy can be used to determine the dielectric constant of the substance, thus identifying its category. Microwaves typically pass through substances in three forms: reflection, absorption, and transmission. Non-metallic containers, such as plastic, ceramic, paper cups, and glass, possess unique penetrating characteristics, with the transmitted energy being essentially equal to the incident energy. Aqueous solutions such as water and beverages have very high dielectric constants, resulting in strong microwave absorption and low reflected energy; conversely, hazardous liquids such as ethanol, ether, and benzene have low dielectric constants, weak microwave absorption, and high reflected energy. By analyzing and processing the echo signal based on information such as travel time, amplitude, waveform, and phase, a threshold can be used to determine the liquid's hazard level.

[0110] To improve the accuracy of detection, in one embodiment, such as Figures 3 to 5As shown, the non-metallic container carrier 221 is provided with a volatile gas inlet 222. The second detection signal also includes a substance detection signal. The non-metallic container detection module 22 further includes a gas detection component 227. The gas detection component 227 is disposed on the non-metallic container carrier 221, opposite to the volatile gas inlet 222, and is used to perform substance detection on the volatile gas of the non-metallic container when the container to be tested is a non-metallic container, so as to generate a substance detection signal; the control module 4 is used to receive the substance detection signal and determine the category of the substance to be tested based on the microwave detection signal and the substance detection signal.

[0111] In this embodiment, as Figure 4 and Figure 5 As shown, the volatile gas inlet 222 is located on the non-metallic container carrier 221 at the position corresponding to the mouth of the container to be tested. The gas detection component 227, as an auxiliary detection module 2, is installed on the non-metallic container carrier 221 and opposite to the volatile gas inlet 222. When there is volatile gas in the non-metallic container and it evaporates from the non-metallic container, the gas detection component 227 can detect its material properties and transmit the detection information to the control module 4. The control module 4 can determine the substance to be tested in the non-metallic container based on the received substance detection signal and microwave detection signal, and jointly determine the substance to be tested in the non-metallic container based on the detection results of both. The non-metallic container detection module 22 also includes a non-metallic detection light barrier 226, which is set on one side of the non-metallic container carrier 221 and electrically connected to the control module 4. It is used to detect whether the container to be tested is placed on the non-metallic container carrier 221, so as to generate a non-metallic container placement signal and transmit it to the control module 4.

[0112] In another embodiment, such as Figure 6 As shown, the microwave detection assembly 223 includes a microwave transceiver 224 and a second control board 225. The microwave transceiver 224 is mounted on the non-metallic container carrier 221 and is electrically connected to the control module 4 for transmitting and receiving microwaves. The second control board 225 is electrically connected to the microwave transceiver 224 and the control module 4, and is used to control the microwave transceiver 224 to perform microwave detection on the substance to be tested in the non-metallic container to generate a microwave detection signal, and transmit the microwave detection signal to the control module 4 so that the control module 4 can determine the category of the substance to be tested.

[0113] In this embodiment, the microwave transceiver 224 can be directly mounted on the non-metallic container carrier 221, thereby enabling it to directly transmit microwave signals to the container under test on the non-metallic container carrier 221. Simultaneously, the microwave transceiver 224 can receive microwave signals reflected by the substance under test within the container, thereby generating a microwave detection signal. The second control board 225 transmits the microwave detection signal to the control module 4. The control module 4 can then determine the category of the substance under test based on the microwave detection signal.

[0114] The working principle of the microwave detection component 223 is as follows: First, the microwave transceiver 224 receives the transmission command through the control module 4 and then transmits microwave signals. These microwave signals pass through the container under test and enter the container. Inside the container, the microwave signals encounter the substance under test and are reflected by it. The reflected microwave signals are received by the microwave transceiver 224 and converted into electrical signals. These electrical signals are transmitted to the control module 4 via the second control board 225. After receiving the microwave detection signals, the control module 4 analyzes and processes the signals. Through the analysis of the microwave detection signals, the control module 4 can determine the category of the substance under test. This process enables rapid and accurate detection of the substance under test.

[0115] In one embodiment, such as Figure 6 As shown, the Raman detection module 7 includes a laser detector 71, a photoelectric conversion board 72, and a third control board 73. The laser detector 71 is electrically connected to the control module 4; the photoelectric conversion board 72 is electrically connected to the control module 4; the third control board 73 is electrically connected to the laser detector 71, the photoelectric conversion board 72, and the control module 4. When the control module 4 reports that the substance to be tested is a hazardous material, the control board 73 controls the laser detector 71 to emit a laser signal towards the substance to be tested, receives the laser signal through the photoelectric conversion board 72, and transmits the received laser signal to the control module 4 so that the control module 4 can determine the specific substance to be tested.

[0116] The Raman detection module 7 is based on the frequency shift of Raman scattered light. During operation, the laser detector head 71 emits a detection laser. When this laser illuminates the substance to be tested, it causes scattering. Compared to the incident light, a small portion of photons in the scattered light have different frequencies. This frequency shift originates from the interaction between photons and molecules. This interaction causes the molecules to vibrate and rotate. Molecular vibration can increase or decrease the energy of photons, thus shifting the frequency of the scattered light. The photoelectric conversion board 72 recovers the scattered light, performs laser signal acquisition and conversion, and the third control board 73 analyzes, filters, and amplifies the signal. The final signal is then fed back to the control module 4, which determines the specific substance to be tested.

[0117] Based on the above embodiments, in some embodiments, such as Figure 1 and Figure 2 As shown, the scanning module 1 includes a barcode scanner, electrically connected to the control module 4, for scanning barcodes and / or QR codes on the container to generate scanning information; the printing module 3 includes a printer, electrically connected to the control module 4, for printing a label containing item information and / or its category based on a signal fed back from the control module 4.

[0118] In this embodiment, a barcode scanner is used to quickly and accurately scan barcodes and / or QR codes on containers. It reads the encoded information on the container and converts it into digital signals. The scanned information typically includes key information such as the container's unique identifier, item name, production date, and expiration date. The operator uses the barcode scanner to scan the barcode or QR code on the container. The scanner converts the scanned encoded information into digital signals. These digital signals are transmitted to the control module 4 via an electrical connection. The control module 4 receives and processes the scanned information, providing basic data for subsequent detection and classification. A printer is used to print labels based on signals fed back from the control module 4. These labels typically include key information such as item information, category, and detection results. The printer is electrically connected to the control module 4 to ensure that it can receive and process printing instructions and related information sent by the control module 4 in real time. According to the instructions from the control module 4, the printer prints labels including item information (such as name, specifications, quantity, etc.), category (such as hazardous materials, general goods, etc.), and the specific substance.

[0119] In some embodiments, such as Figures 1 to 6 As shown, the control module 4 includes a communication unit, a signal processing unit 41, and a processing control unit 42. The communication unit is communicatively connected to the server; the signal processing unit 41 is electrically connected to the communication unit, the barcode scanning module 1, the detection module 2, and the printing module 3, for receiving barcode scanning information and detection signals, and sending the barcode scanning information to the server to receive item information fed back by the server based on the barcode scanning information; the processing control unit 42 is electrically connected to the signal processing unit 41, for determining the category of the substance to be tested based on the detection signal, and for making judgments based on the signal processed by the signal processing unit 41, and for regulating the communication unit, the barcode scanning module 1, the detection module 2, and the printing module 3.

[0120] In this embodiment, the communication unit can reliably communicate with the remote server, upload barcode scanning information, and receive item information from the server. Although the communication unit is mainly responsible for external communication, it also maintains necessary interactions with other modules (such as the signal processing unit 41) to ensure the accuracy and integrity of the data.

[0121] The signal processing unit 41 is responsible for receiving data from the scanning module 1, the detection module 2, and external communications, and performing preliminary processing and analysis. During operation, the signal processing unit 41 obtains the barcode or QR code information of the container from the scanning module 1. The signal processing unit 41 uploads the scanned information to the server and waits for the item information returned by the server. The signal processing unit 41 obtains the detection results of the substance to be tested from the detection module 2. The signal processing unit 41 integrates the scanned information with the item information fed back by the server and the detection signal from the detection module 2, and transmits it to the processing control unit 42 for further processing.

[0122] The processing control unit 42 performs decision analysis based on the data provided by the signal processing unit 41 and issues control commands. Based on the detection signal, the processing control unit 42 can accurately determine the category of the substance to be tested using a preset algorithm or model. According to the analysis results and preset logic, the processing control unit 42 will perform real-time control of the communication unit, barcode scanning module 1, detection module 2, and printing module 3.

[0123] It should be noted that, as Figure 5 As shown, the signal processing unit 41 is communicatively connected to components such as the first control board 2122, the second control board 225, and the third control board 73. All signals transmitted are sent to the signal processing unit 41 for unified processing and feedback. The processing control unit 42 is the central processing control element, used to make judgments based on the signals processed by the signal processing unit 41, in order to regulate other components.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
