[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] This invention employs passive 900MHz radio frequency identification (RFID) technology, an automatic identification technology that uses electromagnetic fields for energy exchange. Compared to traditional active RFID, passive 900MHz RFID does not require a built-in battery, thus offering better anti-interference performance and a longer lifespan, making it suitable for harsh environments such as underground mines.

[0028] In downhole drill pipe counting, the main advantages of passive 900M RFID technology are as follows: 1. Long communication distance: Utilizing the reflection and penetration characteristics of electromagnetic waves, passive 900M RFID technology can achieve signal transmission over long distances, thereby enabling the identification and counting of drill pipes at distant locations. 2. Good anti-collision performance: Due to the high signal sensitivity of passive 900M RFID, it can effectively detect and avoid other interference signals, thus reducing misidentification and collisions when multiple devices are working simultaneously.

[0029] This invention provides a drill pipe identification and counting method based on RFID technology. The drill pipe is equipped with an RFID chip, and an RFID reader is deployed at the drill rig along the middle of the drill pipe's stroke to ensure that the reader can detect the wireless signal from the drill pipe with the RFID chip. See [link to relevant documentation]. Figure 1The diagram shows a schematic flowchart of a drill pipe identification and counting method based on RFID technology. The method includes the following steps:

[0030] S110 uses RFID technology to acquire tag information for drill pipes.

[0031] S120, update the drilling tag queue information based on the tag information.

[0032] Optionally, new tag information or incorrect tag information can be added to the drilling tag queue based on the tag information to update the drilling tag queue information.

[0033] S130, count the number of tags in the drilling tag queue information to perform drilling count.

[0034] S140, update the drill return tag queue information based on the tag information and the drill return tag queue after drilling is completed.

[0035] Optionally, based on the tag information and the drilling tag queue after drilling is completed, new tag information or erroneous tag information can be added to the drilling exit tag queue to update the information of the drilling exit tag queue.

[0036] S150, count the number of tags in the drill rejection tag queue information to perform drill rejection counting.

[0037] This invention provides a drill pipe identification and counting method based on RFID technology. The method acquires drill pipe tag information using RFID technology; updates the drilling tag queue information based on this tag information, ensuring that the drilling tag queue information accurately and promptly reflects the drill pipe's drilling progress, thereby guaranteeing the timeliness and accuracy of subsequent drilling progress counting; counts the number of tags in the drilling tag queue information for drilling progress counting; updates the drill return tag queue information based on the tag information and the drilling tag queue after drilling completion, ensuring that the drill return tag queue information accurately and promptly reflects the drill pipe's return information, thereby guaranteeing the timeliness and accuracy of subsequent drill return counting; and counts the number of tags in the drill return tag queue information for drill pipe return counting. By acquiring drill pipe tag information using RFID technology and continuously updating and counting the number of tags in the drilling tag queue and drill return tag queue, intelligent drill pipe counting is achieved. Furthermore, the reliability of intelligent drill pipe counting is improved through correct identification and accurate counting of the drill pipe.

[0038] Alternatively, as a specific implementation method, see [link to relevant documentation]. Figure 2 The diagram shown is a schematic flowchart of a drill pipe identification and counting system. Figure 3 The diagram shows a schematic flowchart for identifying and counting drill pipe that has been withdrawn from drilling.

[0039] Step S120 above includes: if the above tag information is different from the last tag information in the drilling tag queue, then the above tag information is added to the drilling tag queue as the new last tag information of the drilling tag queue.

[0040] It should be noted that if the tag information is the same as the last tag information in the drilling tag queue, the tag information will continue to be identified and the last tag information in the drilling tag queue will be obtained, indicating that the drilling rig at the drilling site is in the drilling state at this time.

[0041] Step S140 above includes: if the above tag information is the same as the last tag information in the drilling tag queue after drilling is completed, then delete the last tag information in the drilling tag queue after drilling is completed, and add the deleted last tag information in the drilling tag queue after drilling is completed to the drilling exit tag queue as the new last tag information in the drilling exit tag queue.

[0042] It should be noted that if the tag information is different from the last tag information in the drilling tag queue after drilling is completed, the tag information will continue to be identified, and the last tag information in the drilling tag queue and the last tag information in the withdrawal tag queue after drilling is completed will be obtained, indicating that the drilling rig at the drilling site is in the withdrawal state at this time.

[0043] Alternatively, as another specific implementation, see [link to relevant documentation]. Figure 4 Another schematic flowchart showing drill pipe identification and counting is shown. Figure 5 The diagram shows another schematic flowchart for identifying and counting drill pipe ejection.

[0044] Step S120 includes: if the above tag information is different from the last tag information in the drilling tag queue, then determine whether the above tag information is the same as the second-to-last tag information in the drilling tag queue; if the above tag information is the same as the second-to-last tag information in the drilling tag queue, then delete the last tag information in the drilling tag queue; if the above tag information is different from the second-to-last tag information in the drilling tag queue, then add the above tag information to the drilling tag queue as the new last tag information in the drilling tag queue. In this way, by determining whether the above tag information is the same as the second-to-last tag information in the drilling tag queue, it is possible to identify whether there is a drilling anomaly in a timely and accurate manner, so that drilling site personnel can handle the above anomaly in a timely manner.

[0045] It should be noted that if the tag information is the same as the last tag information in the drilling tag queue, the tag information will continue to be identified, and the last tag information and the second-to-last tag information in the drilling tag queue will be obtained, indicating that the drilling rig at the drilling site is in the drilling state at this time.

[0046] Step S140 includes: if the above-mentioned tag information is the same as the last tag information in the drilling tag queue after drilling is completed, then delete the last tag information in the drilling tag queue after drilling is completed, and add the deleted last tag information in the drilling tag queue after drilling is completed to the withdrawal tag queue as the new last tag information in the withdrawal tag queue; if the above-mentioned tag information is not the same as the last tag information in the drilling tag queue after drilling is completed, then determine whether the above-mentioned tag information is the same as the last tag information in the withdrawal tag queue; if the above-mentioned tag information is different from the last tag information in the withdrawal tag queue, then restore the last deleted tag information in the drilling tag queue after drilling is completed to the end of the drilling tag queue after drilling is completed, and delete the last tag information in the withdrawal tag queue. In this way, by determining whether the above-mentioned tag information is the same as the last tag information in the second withdrawal tag queue, it is possible to identify in a timely and accurate manner whether there is a withdrawal anomaly, so that the drilling site staff can handle the above-mentioned anomaly in a timely manner.

[0047] It should be noted that if the tag information is the same as the last tag information in the above-mentioned drill withdrawal tag queue, the tag information will continue to be identified, and the last tag information in the drill entry tag queue and the last tag information in the drill withdrawal queue after the drilling is completed will be obtained, indicating that the drilling rig at the drilling site is in the drill withdrawal state at this time.

[0048] This invention provides a method for handling abnormal situations. Other abnormal situations can be handled by referring to the specific implementation methods described above.

[0049] Optionally, see [link to relevant documentation] Figure 2-5 The above method also includes: continuously acquiring tag information and drilling tag queue information before the drill pipe is fully drilled; continuously acquiring tag information, drilling tag queue information after drilling is fully drilled, and drilling tag queue information before the drill pipe is fully withdrawn.

[0050] Optionally, the above method further includes: after the drill pipe is advanced, sending a drilling completion message to the monitoring system; after the drill pipe is withdrawn, sending a withdrawal completion message to the monitoring system.

[0051] It should be noted that, based on the drilling completion message received by the monitoring system, a command to end drilling or begin retraction can be issued; conversely, a command to end retraction can be issued based on the drilling completion message received by the monitoring system. The completion of drill pipe entry and exit operations can be determined manually.

[0052] This invention provides a specific method for identifying and counting drill pipes based on RFID technology, comprising the following steps:

[0053] 1. Hardware setup: Deploy an RFID reader antenna in the middle of the drill rod stroke at the drilling rig to ensure that the reader can detect the wireless signal of the drill rod with the special anti-metal tag installed;

[0054] 2. Software Algorithm Design: Based on the characteristics of passive 900M RFID technology, a corresponding identification algorithm is designed to analyze the received wireless signal of the drill pipe and determine the forward or backward state of the drill pipe.

[0055] 3. Data Acquisition and Analysis: During the drilling rig's operation, RFID signals are collected and read in real time, and the number of drill rods is identified through analysis algorithms;

[0056] 4. Results Output and Display: The analysis results are presented on the monitoring system in the form of charts or text, making it convenient for operators to view the status of the drill pipe;

[0057] 5. Optimization and Adjustment: Based on the actual application results, optimize and adjust the location, quantity, and performance parameters of the RFID readers to further improve the accuracy and efficiency of downhole drill pipe counting.

[0058] Step 1 above includes: first, drilling a 14mm diameter and 3.5mm deep hole on the drill rod (different labels require different hole diameters) to hold the ceramic label, and then pouring high-temperature and wear-resistant structural adhesive to install and fix the label.

[0059] It should be noted that the drilling rig used in this embodiment of the invention is model 4500, with a drill rod diameter of 73mm. The rated rotation speed is 75r / min, or 1.25r / s. The drilling speed with the tag applied to the drill rod is 3.43m / s. Because the anti-metal tag has a relatively short recognition distance (10-20cm) and a small recognition angle, the reader needs to have a relatively high reading speed. To prevent damage to the tag during drilling, it needs to be embedded in the circular hole, which would weaken the wireless signal. Therefore, the reader needs to have a relatively high power. Testing showed that readers with a power of 30dB or higher performed better.

[0060] See Figure 6 The diagram shows a schematic flowchart of drill pipe identification and counting. In this embodiment of the invention, two queues are used when performing RFID tag identification. One queue is the RFID tag queue during the drilling process, which stores the queue of drill pipes currently installed on the drilling rig, and is called the drilling entry tag queue. The other queue is the queue of drill pipes after the drill pipes are removed from the drilling rig after drilling, and is called the drilling exit tag queue.

[0061] Step 3 above includes: starting drilling operations, identifying RFID tags, and comparing the information of the RFID tag read with the information of the second-to-last tag in the drilling tag queue if the read tag information is different from the information of the last tag in the drilling tag queue. If the read tag information is the same as the second-to-last tag, the last tag information in the drilling tag queue is deleted, indicating that an anomaly has occurred during drilling and the previously drilled area needs to be withdrawn and drilled again; if the read RFID tag is different from the second-to-last tag, a new tag information is added to the end of the drilling tag queue. Manual intervention is used to determine whether drilling can begin. If not, drilling count continues; if so, drilling withdrawal operations begin. Drill withdrawal operations begin, RFID tags are identified, and it is determined whether the read tag information is the same as the tag information at the end of the drilling tag queue. If the read tag information is different from the tag information at the end of the drilling tag queue, it is necessary to determine whether the read tag information is consistent with the tag at the end of the drill withdrawal tag list. If the read tag information is consistent with the tag at the end of the drill withdrawal tag list, it means that the drill pipe is being withdrawn. If the read tag information is inconsistent with the tag at the end of the drill withdrawal tag list, it means that an abnormality has occurred in the drill withdrawal process and the drill withdrawal needs to be restarted. In this case, the deleted tag information needs to be restored to the drilling tag queue. If the read tag information is consistent with the tag information at the end of the drilling tag queue, the tag information at the end of the drilling tag queue is deleted, and this information is added to the drill withdrawal tag queue.

[0062] This invention, through the use of two RFID tag queues, effectively avoids situations where repeated drilling and retraction are necessary during drilling operations due to special circumstances. Conventional AI video analysis methods cannot effectively identify such situations, leading to duplicate counting or omissions. This invention provides a specific RFID-based drill pipe identification and counting method that effectively avoids this problem.
