[0030] Hazardous waste warehouses or temporary storage areas typically store waste with specific hazardous properties. These hazardous wastes may include explosive waste, flammable waste, and waste that releases toxic gases. The very presence of these hazardous wastes implies a potential risk. During storage, improper control of environmental conditions in the warehouse or temporary storage area, such as excessively high or low temperatures or humidity, can affect the stability of the waste. Furthermore, the accumulation of flammable gases at a certain concentration in the air of the warehouse or temporary storage area, or the presence of diffuse smoke (usually flammable particles), all constitute clear safety hazards.

[0031] Understandably, if the aforementioned environmental conditions are abnormal or potential hazards exist, a safety accident may occur. Such accidents may manifest as explosions, fires, or large-scale leaks of toxic gases.

[0032] Based on this, this application proposes an embodiment of a hazardous waste intelligent storage management terminal device, please refer to... Figure 1 , Figure 1 This is one of the structural block diagrams of the intelligent hazardous waste storage management terminal device provided in the embodiments of this application.

[0033] In this embodiment, the hazardous waste intelligent storage management terminal device includes: a hazardous waste storage management module 10, an environmental monitoring module 20, a control module 30, and an alarm module 40.

[0034] The output of the hazardous waste storage management module 10 is connected to the first input of the control module 30; the output of the environmental monitoring module 20 is connected to the second input of the control module 30; and the input of the alarm module 40 is connected to the first output of the control module 30.

[0035] Understandably, the connections between the various modules of a system are essentially electrical signal connections. These connections may take many different forms in practice. For example, the most common method is through wires, which, as the transmission medium for electrical signals, effectively transfer signals from one module to another. In addition, circuit board traces are another important connection method. These traces, carefully designed and laid out, ensure stable signal transmission on the circuit board. Besides wires and circuit board traces, specific communication interfaces and their associated traces may also be used to accomplish signal transmission. These communication interfaces and traces typically offer higher transmission efficiency and more stable performance, making them suitable for scenarios with high signal transmission requirements. In summary, whether through wires, circuit board traces, or specific communication interfaces and traces, the ultimate goal is to ensure smooth transmission of electrical signals between modules.

[0036] It should be noted that the output of the hazardous waste storage management module 10 is connected to the first input of the control module 30. This indicates that the hazardous waste storage management module 10 is primarily responsible for collecting and processing information related to hazardous waste storage management, such as the type, weight, storage location, and entry / exit times of the hazardous waste. After this data is processed and organized internally, it is transmitted to the first input of the control module 30 through its output in the form of a specific electrical signal (such as a digital signal). Therefore, the hazardous waste storage management module 10 is used to transmit identified hazardous waste information to the control module 30.

[0037] Specifically, the hazardous waste storage management module 10 may include components such as sensors, a processor, and a communication interface. Sensors are used to monitor the status of hazardous waste in real time, such as weight changes and location movement, and convert this status information into electrical signals. The processor is responsible for receiving the sensor signals, processing and analyzing the data to extract key information, such as the type, weight, and storage location of the hazardous waste. After processing, this information is transmitted to the control module 30 via the communication interface in the form of specific electrical signals, thereby achieving intelligent monitoring and management of hazardous waste storage. This equipment design can greatly improve the efficiency and accuracy of hazardous waste management, providing strong support for environmental protection work.

[0038] In one feasible implementation, the device connection relationship between the control module 30 and the hazardous waste storage management module 10 is shown. Please refer to... Figure 2 , Figure 2 This is one of the device connection diagrams of the hazardous waste intelligent storage management terminal device provided in the embodiments of this application.

[0039] In this embodiment, the control module 30 includes an industrial control all-in-one computer 31; the hazardous waste storage management module 10 includes a weighing device 11, a label printing device 12, and a barcode scanning device 13.

[0040] The weighing device 11 has its output connected to the first input of the industrial control computer 31; the environmental monitoring module 20 has its output connected to the second input of the industrial control computer 31; the barcode scanner 13 has its output connected to the third input of the industrial control computer 31; the alarm module 40 has its input connected to the first output of the control module 30; and the label printer 12 has its input connected to the second output of the industrial control computer 31. The connection method is an electrical signal connection, as described above, and will not be repeated here.

[0041] It should be noted that the weighing device 11 can be an electronic scale or a weighbridge; the label printing device 12 can be a pre-configured small printer; and the barcode scanning device 13 can be a barcode scanner with a base that can communicate with the industrial control computer 31. The selection of these devices aims to meet the actual needs of hazardous waste storage management and ensure data accuracy and ease of management.

[0042] Understandably, electronic scales or weighbridges, acting as weighing devices 11, provide accurate hazardous waste weight information, which is crucial for the classification, storage, and measurement of hazardous waste. Small printers, acting as label printing devices 12, can quickly print labels containing hazardous waste information, facilitating their affixing to hazardous waste packaging and enabling visualized information management. Barcode scanners, acting as barcode scanning devices 13, can efficiently read the QR codes or barcodes on the labels, quickly inputting hazardous waste information into the system and improving management efficiency.

[0043] It should be noted that the output of the environmental monitoring module 20 is connected to the second input of the control module 30, meaning that the environmental monitoring module 20 is responsible for real-time monitoring of the hazardous waste storage environment, including environmental parameters such as temperature, humidity, methane concentration, and smoke concentration. After analyzing and processing the monitored environmental data, the module transmits an electrical signal representing the environmental state to the second input of the control module 30 through its output. Therefore, the environmental monitoring module 20 is used to transmit the detected environmental information to the control module 30.

[0044] Specifically, the environmental monitoring module 20 can include various sensors, such as temperature sensors, humidity sensors, methane sensors, and smoke sensors. These sensors are used to detect key parameters in the hazardous waste storage environment, such as temperature, humidity, methane concentration, and smoke concentration. By integrating these sensors, the environmental monitoring module 20 can acquire real-time and accurate status information of the storage environment, providing basic data for subsequent data processing and analysis. Furthermore, these sensors typically feature high precision, high stability, and long lifespan, ensuring the accuracy and reliability of environmental monitoring.

[0045] In one feasible implementation, the device connection relationship between the control module 30 and the environmental monitoring module 20 is given; please refer to [reference needed]. Figure 3 , Figure 3 This is the second device connection diagram of the hazardous waste intelligent storage management terminal device provided in the embodiments of this application.

[0046] In this embodiment, the environmental monitoring module 20 includes a temperature and humidity sensor 21, a methane sensor 22, and a smoke sensor 23. The output terminals of the temperature and humidity sensor 21, the methane sensor 22, and the smoke sensor 23 are all connected to the second input terminal of the control module 30. The connection method is an electrical signal connection, as described above.

[0047] Specifically, the temperature and humidity sensor 21, the methane sensor 22, and the smoke sensor 23 are all equipped with Modbus interfaces; the temperature and humidity sensor 21, the combustible gas sensor 22, and the smoke sensor 23 are all connected to the second input terminal of the control module 30 via a shared 485 bus through the Modbus interface.

[0048] Understandably, this design not only simplifies the connection between the sensor and the control module but also improves the efficiency and stability of data transmission. The Modbus interface, as a widely used communication protocol, offers excellent compatibility and reliability, meeting the needs of various industrial applications. Meanwhile, the RS-485 bus, as a differential transmission bus standard, boasts advantages such as strong anti-interference capabilities and long transmission distances, making it suitable for data communication between the sensor and the control module in this embodiment. Through this connection method, the temperature and humidity sensor 21, the methane sensor 22, and the smoke sensor 23 can transmit monitoring data to the control module 30 in real time and accurately, providing strong support for subsequent storage environment management and safety early warning.

[0049] It should be noted that after receiving hazardous waste information from the hazardous waste storage management module 10 and environmental information from the environmental monitoring module 20, the control module 30 will perform a comprehensive analysis. It may determine, based on preset rules or algorithms, whether the current storage status of the hazardous waste is safe and whether the storage environment is suitable. If the control module 30 detects that the hazardous waste is improperly stored, or that the temperature or humidity of the storage environment exceeds safe limits, it may immediately trigger the alarm module 40. Upon receiving the alarm signal from the control module 30, the alarm module 40 will immediately activate the alarm mechanism, alerting operators through sound, light, or other means so that timely measures can be taken to ensure the safe storage of the hazardous waste.

[0050] Specifically, the preset rules could involve performing an initialization operation after system startup to complete the device startup and pre-set key threshold parameters for determining whether air conditions are safe. Subsequently, the system enters a continuous monitoring cycle: collecting ambient air sample data through sensors. The collected air data is sent to the system for analysis and processing. The system compares the analyzed real-time detection data with the pre-set thresholds to determine whether the detection value exceeds the safe range.

[0051] It should be noted that if the detected value does not exceed the threshold, the system considers the current air quality to be safe and automatically returns to the sensor data acquisition and analysis step, continuously looping the monitoring task. If the detected value is determined to exceed the preset threshold, the system immediately triggers the audible and visual alarm device, issuing an audible and visual alarm signal to indicate an abnormality. After entering the alarm state, the system does not stop monitoring but continues to collect and analyze air data through the sensors. In this state, the system continuously performs a secondary comparison between the newly acquired detection data and the threshold to check whether the value has fallen back to a safe range.

[0052] It should be noted that the system will only determine that the air quality has returned to normal and execute the operation to disable the audible and visual alarms once the detection data is confirmed to have stably recovered to a safe level below the threshold. This completes the closed-loop detection and alarm process. The entire process clearly demonstrates the logical closed-loop workflow of the equipment from startup, monitoring, judgment, alarm, to alarm deactivation.

[0053] In one feasible implementation, the device connection relationship between the control module 30 and the alarm module 40 is given; please refer to [reference needed]. Figure 4 , Figure 4 This is the third device connection diagram of the hazardous waste intelligent storage management terminal device provided in the embodiments of this application.

[0054] In this embodiment, the alarm module 40 includes an alarm device 42 and a relay 41. The input terminal of the alarm device 42 is connected to the first output terminal of the control module 30 via the relay 41.

[0055] It should be noted that the alarm device 42 can be an audible and visual alarm. Upon receiving an alarm signal from the control module 30, this alarm will immediately activate, emitting a loud sound and flashing lights to quickly attract the attention of those nearby, allowing them to take timely countermeasures. Furthermore, the alarm device 42 is designed with durability and stability in mind, ensuring it maintains good working condition during long-term use and will not malfunction due to frequent use or environmental factors.

[0056] It is understood that the input terminal of the alarm device 42 is electrically connected to the relay 41. Upon receiving an alarm signal, the relay 41 quickly switches its operating state, thereby activating the input circuit of the alarm device 42 and enabling the alarm device 42 to start. This electrical connection not only ensures accurate transmission of the alarm signal but also effectively improves the response speed and reliability of the entire hazardous waste intelligent storage management terminal device. The relay 41 is electrically connected to the industrial control integrated computer 31, as described above.

[0057] Specifically, relay 41 is equipped with a Modbus interface; relay 41 is connected to the first output terminal of control module 30 via the Modbus interface and the 485 bus. It is understood that environmental monitoring module 20 and alarm module 40 can also share the 485 bus to achieve control integration. In other words, temperature and humidity sensor 21, methane sensor 22, smoke sensor 23, relay 41, and the industrial control computer adopt a Modbus device interconnection method based on RS485 bus, where the master device is the industrial control computer, and the three sensors and relay are slave devices, communicating via a shared RS485 line through a star topology of the Modbus gateway.

[0058] Understandably, data transmission and command issuance between the environmental monitoring module 20 and the alarm module 40 can be efficiently completed via the 485 bus, reducing wiring complexity and improving the overall stability and ease of maintenance of the system. The environmental monitoring module 20 is responsible for real-time monitoring of environmental parameters within the hazardous waste storage area, such as temperature, humidity, and gas concentration. Once an anomaly is detected, it immediately sends an alarm message to the control module 30 via the 485 bus. Upon receiving the alarm message, the control module 30 can not only activate the alarm device 42 via the relay 41, but also synchronize the alarm message to the industrial control computer 31 via the 485 bus for further data analysis and recording. This integrated control method not only improves the intelligence level of the hazardous waste intelligent storage management terminal device, but also enables managers to have a more comprehensive understanding of the hazardous waste storage status, take timely action, and ensure environmental safety and personnel health.

[0059] In addition, please refer to Figure 5 , Figure 5 This is a second structural block diagram of the intelligent hazardous waste storage management terminal device provided in this application embodiment. The intelligent hazardous waste storage management terminal device further includes: a data transmission module 50; the first input terminal of the data transmission module 50 is connected to the third output terminal of the control module 30; the data transmission module 50 is used to transmit hazardous waste information and environmental information received from the control module 30 to the Internet of Things information management system. The output terminal of the alarm module 40 is connected to the second input terminal of the data transmission module 50; the data transmission module 50 is also used to transmit alarm information received from the alarm module 40 to the user terminal.

[0060] Understandably, through the data transmission module 50, the intelligent hazardous waste storage management terminal device can synchronize key information to the Internet of Things (IoT) information management system in real time, achieving centralized management and remote monitoring of information. Once an anomaly occurs in the hazardous waste storage area, alarm information not only triggers a local alarm immediately but also quickly transmits it to user terminals, such as managers' mobile phones or computers, ensuring that managers can obtain alarm information and react swiftly regardless of their location. This design greatly enhances the timeliness and efficiency of hazardous waste management and reduces potential environmental risks and safety hazards.

[0061] In its implementation, the data transmission module 50 can be a module based on wireless communication technology, such as 4G, 5G, Wi-Fi, or Bluetooth. These technologies feature high-speed data transmission and wide coverage, ensuring that hazardous waste and environmental information is transmitted to the IoT information management system in real time and accurately. Simultaneously, the data transmission module 50 supports bidirectional communication, enabling it to not only send data to the management system but also receive instructions or configuration information from user terminals, thus achieving remote management and control. Furthermore, to enhance the stability and reliability of data transmission, the data transmission module 50 may also have data encryption and error checking functions to ensure the security and integrity of information during transmission.

[0062] In this embodiment, by employing a hazardous waste storage management module to transmit identified hazardous waste information to the control module, the status of hazardous waste can be monitored in real time, thus solving the problem of untimely updates to the entry and exit status of hazardous waste in existing technologies. The environmental monitoring module transmits detected environmental information from the surrounding environment to the control module, enabling immediate capture of changes in environmental parameters, thus overcoming the shortcomings of isolated monitoring of environmental factors in existing technologies. The control module converts the received hazardous waste and environmental information into alarm signals and outputs them to the alarm module, realizing intelligent analysis and judgment of potential hazardous waste spill hazards, thus eliminating the risk of delayed manual decision-making. The alarm module sounds an alarm upon receiving the alarm signal, ensuring rapid response and execution, thus solving the problem of delayed emergency measures. Overall, real-time monitoring and automatic alarm for hazardous waste management are achieved, effectively reducing the safety hazards of hazardous waste spills in the warehouse. Compared with existing technologies, this reduces the probability of safety accidents and improves management efficiency and safety.

[0063] Furthermore, this application provides an embodiment of the installation and layout of an intelligent hazardous waste storage management terminal device. Please refer to... Figure 6 , Figure 6 This is an installation layout diagram of the intelligent hazardous waste storage management terminal device provided in the embodiments of this application.

[0064] In this embodiment, the intelligent hazardous waste storage management terminal device further includes: a cabinet 60; the cabinet 60 is divided into multiple sub-cabinets; the multiple sub-cabinets are used to house each module respectively. The sub-cabinets may be equipped with heat dissipation devices to ensure the stability of each module under high load operation. The front panel of the cabinet 60 is equipped with a touch screen display and operation buttons for user operation and monitoring. In addition, the bottom of the cabinet 60 is equipped with casters to facilitate the movement and arrangement of the entire device, enhancing its practicality and flexibility. The connections between the modules adopt standardized interfaces to ensure the stability and reliability of data transmission, while also facilitating maintenance and upgrades.

[0065] Understandably, dividing the cabinet 60 into multiple sub-cabinets helps improve the overall performance and maintainability of the intelligent hazardous waste storage management terminal device. Each sub-cabinet can operate and be managed independently. When a module malfunctions, it can be quickly located, repaired, or replaced without affecting the normal operation of other modules. This modular design not only improves the reliability and stability of the equipment but also effectively reduces maintenance costs and time.

[0066] Specifically, the cabinet 60 has a relatively complex structural design with clearly defined functional zones. It consists of at least seven sub-cabinets arranged from top to bottom, and the top is equipped with an alarm light for abnormal status indication. The topmost sub-cabinet 61 houses an industrial control all-in-one computer 31, which serves as the core control device to coordinate the overall operation. The second sub-cabinet 62 below it has a built-in printer to meet label output requirements. The third sub-cabinet 63 adopts a drawer-type design, with a built-in keyboard and mouse that can be pulled out for operation when in use and stored away to save space when not in use.

[0067] Specifically, the fourth sub-cabinet 64 houses a weighing device 11, such as an electronic scale, for detecting the weight of items; the fifth sub-cabinet 65 has a more diverse configuration, integrating an RS485 to RS232 converter for signal conversion, a relay 41 for controlling the on / off state of the circuit, a surge protector to prevent power surges, a temperature and humidity sensor 21 for monitoring environmental parameters, a methane sensor for detecting methane concentration, and a smoke sensor 23 for sensing smoke. These devices work together to ensure the safety and stability of the storage environment.

[0068] Specifically, the sixth sub-cabinet 66 is mainly used to store label paper consumables, providing power to the printing equipment; the bottom seventh sub-cabinet 67 is equipped with multiple sockets, providing power interfaces for various devices within the cabinet. The overall layout, from top to bottom, covers control, output, operation, detection, environmental monitoring, consumable storage, and power supply functions, reflecting the characteristics of modular design and functional integration.

[0069] Among them, the temperature and humidity sensor 21, the methane sensor, and the smoke sensor 23 need to be installed at a height of approximately 0.7 meters above the ground; therefore, the fifth sub-cabinet 65 is a suitable choice. The temperature and humidity sensor 21, the methane sensor, and the smoke sensor 23 are each connected to an RS485 to RS232 converter via a 485 bus; the alarm light is electrically connected to the relay 41, which is connected to the RS485 to RS232 converter via a 485 bus; the RS485 to RS232 converter is connected to the industrial control all-in-one computer 31.

[0070] It should be understood that expressions such as “comprising” and “may include” used in this application indicate the existence of the disclosed functions, operations, or constituent elements, and do not limit one or more additional functions, operations, and constituent elements. In this application, terms such as “comprising” and / or “having” are to be interpreted as indicating a particular characteristic, number, operation, constituent element, component, or combination thereof, but not to exclude the existence or possibility of adding one or more other characteristics, numbers, operations, constituent elements, components, or combinations thereof.

[0071] Furthermore, in this application, the expression "and / or" includes any and all combinations of the associated listed words. For example, the expression "A and / or B" may include A, may include B, or may include both A and B.

[0072] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the components can rotate relative to each other after connection. "Sliding connection" refers to a connection where the components can slide relative to each other after connection.
