Description

Technical Field

[0001] This invention belongs to the field of quicklime sampling technology, and specifically relates to a quicklime barcode sampling risk control device and its risk control method. Background Technology

[0002] Quicklime is an important raw material in ironmaking. High-quality quicklime can provide sufficient calcium oxide, effectively remove sulfides, and regulate the alkalinity in the furnace, thereby promoting the ironmaking reaction and improving iron quality. The quality of quicklime plays a crucial role in the smooth progress of the ironmaking process and the improvement of iron quality. Currently, the specific sampling procedure for quicklime in most steel plants is as follows: After the truck enters the gate, it passes through the metering equipment to generate metering information; the truck drives to the sampling point, the driver manually connects the sampling equipment pipeline, and starts the sampling machine by pressing the start switch or swiping a card. After sampling, the relevant sampling information (license plate and manufacturer, etc.) is recorded; the sampling worker periodically removes the sample from the sampling machine, seals it, and sends it for testing.

[0003] Throughout the quicklime sampling process, the driver can start the sampler multiple times, posing a risk of sample replacement midway through the process; sampling information is filled out manually, resulting in low automation; and sensitive information about the sampled materials is relatively transparent, making it easy to leak or replace. A review of corruption cases in major steel mills in recent years reveals that many occur during the raw material receiving and inspection processes. Taking quicklime as an example, unscrupulous individuals exploit these loopholes to replace inspection samples for personal gain. This undermines the transparency, fairness, and impartiality of quicklime inspection; affects ironmaking quality; and causes significant losses to the company.

[0004] Currently, most steel mills solve this problem by adding surveillance cameras. Manual inspection is labor-intensive and cannot achieve 24-hour full-process, full-lifecycle tracking and control.

[0005] Some steel mills use card-based sampling equipment, with the following process: First, a card needs to be issued at the gate; then, the card is swiped on the sampling equipment, and vehicle information is manually registered; finally, the card is retrieved before leaving the station. This process is not only cumbersome but also cannot ensure a one-to-one correspondence between the sampling vehicle and the card. Furthermore, when cards are abnormal, damaged, or lost, manual handling is required, affecting sampling efficiency.

[0006] In existing technologies, important information in the sampling process is isolated and cannot be correlated and matched. Summary of the Invention

[0007] Purpose of the invention: To address the problems existing in the prior art, this invention provides a quicklime barcode sampling risk control device and its risk control method, which achieves full automation, reduces labor costs, and makes quicklime inspection more fair and impartial.

[0008] Technical solution: To solve the above technical problems, the present invention provides a quicklime barcode scanning sampling risk control device, including a display module, a vision module, a memory, a processor and a communication module, wherein the communication module is connected to an external camera, a sampler, a label printer and a three-level system;

[0009] The processor is connected to the display module, the vision module, the memory, and the communication module;

[0010] The vision module is used for collecting, processing, and transmitting information about vehicles and personnel.

[0011] The memory is used to store control programs and system data.

[0012] Furthermore, the display module includes a display screen and an alarm light.

[0013] Furthermore, the alarm light is divided into green, yellow, and red. A green alarm light indicates normal operation, a yellow alarm light indicates an abnormal situation, and a red alarm light indicates a device malfunction.

[0014] Furthermore, the vision module includes several internal cameras.

[0015] A risk control method for a quicklime barcode sampling risk control device as described above includes the following steps:

[0016] Step 1: Generate sampling code and weigh the vehicle: After purchasing the designated weighing plan, a sampling code is generated, and the driver uses the sampling code to weigh the vehicle.

[0017] Step 2: The driver uses the QR code scanning sampling risk control device to scan and sample: The driver scans the sampling code, and after the information is verified, the sampler starts automatically. After sampling is completed, the sample bag code is printed and the printed information is uploaded.

[0018] Step 3: The sampling worker uses the QR code scanning sampling risk control device to submit the sampling personnel information: The sampling worker periodically takes out the sample from the sampler, seals and labels it, and submits the sampling information after facial recognition.

[0019] Furthermore, the specific steps for generating the sampling code and weighing in step 1 are as follows:

[0020] Collect the weighing plan number, license plate number, unique number, and warehouse number, and convert the collected weighing plan number, license plate number, unique number, and warehouse number into sampling codes; the driver uses the converted sampling codes to weigh the vehicle.

[0021] Furthermore, the specific steps for the driver to use the QR code scanning sampling risk control device to perform QR code sampling in step 2 are as follows:

[0022] Step 2.1: The driver parks the truck at the designated location for quicklime sampling and manually connects the sampler's pipe to the discharge port at the rear of the tanker truck. After confirming that everything is correct, the driver displays the QR code for scanning the sample in front of the external barcode scanner of the barcode sampling risk control device.

[0023] Step 2.2: The quicklime scanning sampling risk control device reads the license plate number, unique number, plan number, and warehouse number information from the sampling QR code; simultaneously, it controls the external camera, i.e., the license plate recognition camera, to take a picture, perform license plate recognition, and compare it with the license plate recognized by the QR code; if the comparison fails, the alarm light in the control display module displays yellow to indicate that the QR code is abnormal, the display screen shows the abnormal information, and the abnormal information is uploaded to the alarm system; if the comparison is successful, proceed to step 2.3;

[0024] Step 2.3: If the comparison is successful, the quicklime barcode sampling risk control device will determine whether the number of samples taken by the sampler exceeds the sampling limit (e.g., 6 samples; the sampling worker must manually remove the samples before the number of samples exceeds 6). If it exceeds the limit, the alarm light will sound, and personnel will be notified to reset the sampler; if it does not exceed the limit, proceed to Step 2.4:

[0025] Step 2.4: If the maximum sampling quantity of the sampler is not exceeded, the quicklime barcode sampling risk control device checks the approval system for a second barcode scanning application based on the unique number obtained in Step 2.2. If there is no application, it is marked as a first barcode scan and a first barcode scanning sampling is performed. If there is an application, it is determined whether the application has been approved. If it has not been approved, an alarm light is used to prompt and the sampling action is stopped. If the application has been approved, it is marked as a second barcode scan and a second barcode scanning sampling is performed.

[0026] Step 2.5: The quicklime scanning and sampling risk control device checks whether the vehicle's weighing information exists in the metering system based on the unique number and sampling mark. If it does not exist, the device controls the alarm to display a yellow warning indicating an abnormality, displays the abnormal information on the interface, and uploads the abnormal information to the alarm system. If it exists, proceed to step 2.6.

[0027] Step 2.6: If present, use the quicklime barcode scanning sampling risk control device to call the random algorithm to generate a random and unique sample bag code;

[0028] Step 2.7: Control the sampler to start working. If the sampler is detected to start working, mark the sampling code as invalid (to prevent scanning the code again for sampling). The alarm indicator light will be green to show that sampling is in progress.

[0029] Step 2.8: After sampling begins, the quicklime scanning sampling risk control device controls the monitoring camera to take a picture every fixed time interval (the fixed time can be adjusted according to actual needs, and can be any time between 1 and 30 minutes), and compares the license plate with the scanned license plate to prevent vehicle switching during the sampling process; if the comparison fails, an alarm information is uploaded to the monitoring system; the quicklime scanning sampling risk control device sets an upper limit time for sampling for each vehicle (the upper limit time can be adjusted according to actual needs, and can be any time between 30 and 60 minutes), and automatically stops sampling if the sampling time exceeds the upper limit time;

[0030] Step 2.9: After receiving the completed sampling, record the sampling end time and related sampling information;

[0031] Step 2.10: The quicklime scanning and sampling risk control device controls the marking machine to print the sample bag code generated in step 2.6;

[0032] Step 2.11: After printing, the quicklime scanning and sampling risk control device will upload all sampling information to the three-level system.

[0033] Furthermore, the specific steps for the secondary barcode scanning and sampling in step 2.4 are as follows:

[0034] Step 2.4.1: After contacting the anomaly handling personnel, the truck driver scans the sampling code again on the external barcode scanner;

[0035] Step 2.4.2: The anomaly handling personnel verify the scanning information displayed on the interface of the quicklime scanning sampling risk control device with the actual license plate information on site, as well as the abnormal phenomena on site;

[0036] Step 2.4.3: The anomaly handling personnel select the information indicating an anomaly on the quicklime barcode sampling risk control device interface and click the submit application button;

[0037] Step 2.4.4: After the face verification box pops up, verify the personnel information. If the verification is successful, the approval will be initiated automatically.

[0038] Furthermore, the specific steps for generating a random and unique sample bag code in step 2.6 are as follows:

[0039] The unique sample bag code is a 12-digit random number. The first 6 digits are a time-based random number, the middle 4 digits are a 4-digit random number with the sampling location number as a fixed interval, and the last 2 digits are the sample bag location number in the sampling machine.

[0040] Furthermore, the specific steps for the sampling worker to submit sampling personnel information using the QR code scanning sampling risk control device in step 3 are as follows:

[0041] Step 3.1: After arriving at the sampling point, manually remove the sample from the sampler and put it into the sampling bag, placing it in the order of the numbers in the sequential sampler;

[0042] Step 3.2: The sampling worker goes to the printer, tears off the sample bag code label, and affixes the sample bag code label to the seal of the sample bag in the printing order;

[0043] Step 3.3: The sampling worker clicks the personnel login button on the quicklime scanning sampling risk control device to log in via facial recognition;

[0044] Step 3.4: The sampling worker scans the sample bag codes pasted in step 3.2 using the front-facing camera of the quicklime scanning sampling risk control device;

[0045] Step 3.5: The quicklime barcode scanning and sampling risk control device identifies the sample bag codes and displays the identified sample bag codes on the interface;

[0046] Step 3.6: The sampling worker clicks the confirmation button on the interface, and the quicklime scanning sampling risk control device uploads the sampling time and personnel information of the sampling worker to the three-level system;

[0047] Step 3.7: After the sampling information is uploaded, the quicklime scanning sampling risk control device sends a reset signal to the sampler to start the next round of sampling process.

[0048] Compared with the prior art, the advantages of the present invention are as follows:

[0049] (1) The entire quicklime sampling process described in this invention adopts the "one-code-pass" mode. Relying on the QR code, one-time activation of sampling is achieved, eliminating the risks of repeatedly turning on the equipment, repeatedly sampling, and changing samples midway.

[0050] (2) The sample bag code is affixed to the surface of the sample packaging bag of the present invention. The sample bag code information is a meaningless random code to avoid leakage of sensitive information.

[0051] (3) All data generated during the risk control method described in this invention can be automatically uploaded to the "Level 3 System" through this device, and all information of the system can be linked together to realize the full life cycle monitoring of the sampling process, and greatly improve the digitalization of quicklime sampling;

[0052] (4) The risk control method described in this invention can be simultaneously extended to any incoming material sampling system. Attached Figure Description

[0078] Collect the weighing plan number, license plate number, unique number, and warehouse number, and convert the collected weighing plan number, license plate number, unique number, and warehouse number into sampling codes; the driver uses the converted sampling codes to weigh the vehicle.

[0079] Step 2: The driver uses the QR code scanning sampling risk control device to scan and sample: The driver scans the sampling code, and after the information is verified, the sampler starts automatically. After sampling is completed, the sample bag code is printed and the printed information is uploaded.

[0080] Step 2.1: The driver parks the truck at the designated location for quicklime sampling and manually connects the sampler's pipe to the discharge port at the rear of the tanker truck.
