Description

Technical Field

[0001] This invention relates to the technical field of data processing and industrial control, and in particular to an intelligent terminal device for the whole-process monitoring of hazardous waste. Background Technology

[0002] Precise, end-to-end monitoring of hazardous waste is a key focus and challenge in environmental governance. With the deepening of "zero-waste city" initiatives, regulatory authorities have placed extremely high demands on the authenticity of data, operational standardization, and full-chain traceability at each stage of hazardous waste generation, temporary storage, transfer, and disposal. However, current on-site hazardous waste management equipment and control methods have the following deficiencies: Under the existing operational model, waste-generating units mostly adopt a fragmented process of "weighing on a weighbridge, manual recording, and post-event data entry": operators first read the weight data using independent weighing equipment, then manually fill in paper ledgers, and finally assign a dedicated person to enter the ledger information into the information system. In this chain, each manual transcription and entry constitutes a potential error-inducing node, such as reading errors, transcription errors, unit confusion, and identification deviations due to illegible handwriting. Especially during peak waste generation periods, the pace of operation accelerates, and the probability of errors increases significantly. As a result, the hazardous waste management data obtained by the regulatory authorities cannot accurately reflect the actual amount of hazardous waste generated, temporarily stored, and disposed of, reducing the data's supporting value for decision-making.

[0003] While some existing hazardous waste management auxiliary equipment on the market possesses basic data collection and label printing functions, it is essentially a "passive data collection tool." The equipment itself only receives and outputs data, lacking the ability to actively verify the data's validity. Specifically, existing equipment cannot determine whether weighing data falls within the normal fluctuation range for the corresponding hazardous waste category, cannot identify whether operators have mislabeled Class A hazardous waste as Class B, and cannot effectively prevent the immediate printing and reporting of data after human intervention. This "collect only, do not verify" technical architecture leaves obvious loopholes for cheating and compliance in actual operation. Summary of the Invention

[0004] In order to enable the intelligent terminal equipment for hazardous waste to automatically collect, verify in real time, and block the outflow of abnormal data at the data generation end, this application provides an intelligent terminal equipment for the whole process supervision of hazardous waste.

The process control module is used to trigger the label printing unit to print hazardous waste labels and upload data through the network communication unit when the data fit index reaches the preset qualified threshold; when the data fit index does not reach the preset qualified threshold, it refuses to execute subsequent operations and issues an abnormal prompt through the human-computer interaction unit.

[0011] Preferably, it also includes a power management unit disposed inside the terminal housing. The power management unit includes an AC / DC power adapter and a built-in rechargeable lithium battery. The built-in rechargeable lithium battery can maintain normal operation of the device for no less than 30 minutes when the external power is interrupted.

[0021] This application discloses an intelligent terminal device for the whole-process monitoring of hazardous waste. (Refer to...) Figure 1 , Figure 2 and Figure 3The intelligent terminal equipment for the whole process monitoring of hazardous waste includes a terminal housing 1. The terminal housing 1 is welded from cold-rolled steel plate and the surface is powder coated. The protection level reaches IP42, which can adapt to the harsh environment of the industrial site. The bottom of the terminal housing 1 is equipped with four universal casters 11, two of which are equipped with brake devices to facilitate the movement and fixing of the equipment in the workshop.

[0022] Inside the terminal housing 1, from top to bottom, are arranged a label printing unit 4, a main control unit 3, and a power management unit 12.

[0023] A 15.6-inch capacitive touch screen is embedded in the upper front of the terminal housing 1, serving as the human-computer interaction unit 2. It is used to display the operation interface, input user information, and display the system status. A label output port 41 is provided below the touch screen, which is connected to the internal label printing unit 4.

[0024] The main control unit 3 uses an RK3576 octa-core processor, is equipped with 4GB DDR4 RAM and 32GB eMMC non-volatile memory, and integrates a USB interface 31, an RS232 interface 32, an RS485 interface 33 and a Gigabit Ethernet interface 34. All interfaces are brought out to the side of the terminal housing 1 for easy connection of external devices.

[0025] Among them, the USB interface 31 is used as a print control interface and input interface; the RS232 interface 32 is used as a first communication interface; the Ethernet interface 34 is used as a second communication interface; and the RS485 interface 33 is used as an extended communication interface to connect external devices such as hazardous waste storage location sensors, explosion-proof alarms, and PLC controllers to realize functional expansion.

[0026] The label printing unit 4 uses an industrial-grade thermal printer, which is electrically connected to the printing control interface of the main control unit 3. It supports printing three common sizes of self-adhesive hazardous waste labels: 10×10cm, 15×15cm and 20×20cm. The printing resolution is 300DPI and the printing speed can reach 150mm / s.

[0027] The barcode scanning and identification unit includes a wireless barcode receiving module 5 and a paired wireless barcode scanner 6. The wireless barcode receiving module 5 is connected to the main control unit 3 via a USB interface 31 and adopts 2.4G wireless communication technology with a communication distance of up to 10 meters, which can meet the operational needs in the workshop. The wireless barcode scanner 6 supports fast scanning and identification of one-dimensional and two-dimensional barcodes and can read various marking information on hazardous waste packaging.

[0028] The weighing communication unit 7 is connected to the main control unit 3 via the RS232 interface 32. It also has a built-in Bluetooth 5.0 module, which supports both Bluetooth and RS232 communication methods. It can establish communication connections with most models of explosion-proof weighbridges on the market and obtain the weighing data of hazardous waste in real time.

[0029] The network communication unit 9 is connected to the main control unit 3 via a gigabit Ethernet interface 34. It also has a built-in Wi-Fi wireless communication module, which supports both wired and wireless network access. When the wired network fails, the system can automatically switch to the Wi-Fi network to ensure that data can be uploaded to the environmental monitoring platform 10 in real time.

[0030] The power management unit 12 is located at the bottom inside the terminal housing 1. It includes an AC / DC power adapter and a built-in 12V / 10Ah rechargeable lithium battery. The AC / DC power adapter has an input voltage of 100-240VAC and an output voltage of 12VDC, which powers the main control unit 3 and various functional modules. The built-in lithium battery can maintain the normal operation of the device for no less than 30 minutes when the external power is interrupted, ensuring that the ongoing operation can be completed smoothly.

[0031] The digital safety verification unit 13 runs on the processor of the main control unit 3 in the form of a software module, specifically including a hazardous waste parameter storage module 131, a data comparison module 132, and a process control module 133.

[0032] The hazardous waste parameter storage module 131 contains pre-stored information on all categories of hazardous waste in the National Hazardous Waste List, including the standard density range of each type of hazardous waste, the normal weight range of a single container, historical average weight data, and abnormal thresholds. These parameters can be updated and maintained by the administrator according to the actual situation of the enterprise.

[0033] The data comparison module 132 is used to compare the real-time weighing data obtained by the weighing communication unit 7 with the preset verification parameters of the corresponding hazardous waste type, and calculate the data fit index. The formula for calculating the fit index is: Fit = 1 - |actual weighing value - theoretical calculated value| / theoretical calculated value. Wherein, the theoretical calculated value is calculated based on the standard density of the hazardous waste type and the volume of the packaging container.

[0034] The process control module 133 is used to control subsequent operation processes based on the calculation results of the data comparison module 132: when the fitting degree index reaches the preset qualified threshold, the data is judged to be normal, the label printing unit 4 is triggered to print the hazardous waste label, and the hazardous waste information and weighing data are uploaded to the environmental protection supervision platform 10 through the network communication unit 9; otherwise, when the fitting degree index does not reach the preset qualified threshold, the data is judged to be abnormal, the subsequent label printing and data uploading operations are refused, and an abnormal prompt is issued through the touch screen and the built-in sound and light prompt unit 14, requiring the operator to check.

[0035] The workflow of an intelligent terminal device for the whole-process monitoring of hazardous waste, according to an embodiment of this application, is as follows: Step S1. System Login and Identity Verification: Operators verify their identity by entering their username and password on the touch screen. After successful system verification, they enter the main operation interface. Step S2. Hazardous waste code scanning and identification: The operator uses the wireless barcode scanner 6 to scan the barcode or QR code on the hazardous waste packaging. The scanning and identification unit transmits the identified hazardous waste code information to the main control unit 3. Step S3. Hazardous waste basic information retrieval: The main control unit 3 retrieves detailed information about the hazardous waste from the local database or the environmental supervision platform 10 based on the hazardous waste code, including the hazardous waste name, category, code, generating unit, etc. Step S4. Hazardous waste weighing data acquisition: The operator places the container containing hazardous waste on the explosion-proof weighbridge. The weighing communication unit 7 acquires the weighing data of the weighbridge in real time and transmits the data to the main control unit 3. Step S5. Weighing data safety verification: The digital safety verification unit 13 retrieves the corresponding standard density range and conventional weight range from the hazardous waste parameter storage module 131 according to the type of hazardous waste. The data comparison module 132 compares the real-time weighing data with the preset parameters and calculates the fitting index. Step S6. Verification Result Processing and Label Generation: Process control module 133 determines whether the fit index has reached the preset qualified threshold. If the threshold is reached, the system automatically generates a hazardous waste label containing hazardous waste information, weighing data, operator information, operation time, etc., and controls the label printing unit 4 to print the label. If the threshold is not reached, the system will display abnormal information on the touch screen and issue an audible and visual prompt, requiring the operator to check whether the hazardous waste category is correct and whether the weighing is accurate, and to repeat the operation after the problem is resolved. Step S7. Labeling and Operation Confirmation: The operator affixes the printed label to the hazardous waste packaging, and clicks the "Complete" button after confirming that everything is correct. Step S8. Data Encryption Upload and Warehousing Registration: The main control unit 3 encrypts and uploads all data from this operation to the environmental protection supervision platform 10 through the network communication unit 9, completing the hazardous waste warehousing registration.

[0036] This application also discloses a hazardous waste full-process monitoring system, including: the above-mentioned intelligent terminal equipment for hazardous waste full-process monitoring; an external weighing device 8, which is communicatively connected to the weighing communication unit 7 of the intelligent terminal equipment; and an external environmental protection monitoring platform 10, which is communicatively connected to the network communication unit 9 of the intelligent terminal equipment.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
