Description

Technical Field

[0001] The present application relates to the technical field of evaluation and testing of on-site ground penetration transmission capability before the implementation of a wireless electronic detonator project, and in particular to a ground penetration testing device and testing method for wireless electronic detonators. Background Art

[0002] The wireless electronic detonator system consists of a command transmitter unit, an initiator, and wireless electronic detonators. Above ground, the initiator uses wireless signals to control the command transmitter unit to transmit a low-frequency signal. Because low-frequency signals can propagate through the ground, they transmit the command to the wireless electronic detonator in the deep hole. Upon receiving the command, the wireless electronic detonator detonates the explosives, achieving the blasting effect. The command transmitter unit comprises an above-ground communication module, a controller (including a low-frequency modulator), a power amplifier, and a transmitting antenna. It radiates the low-frequency signal (typically between 1kHz and 300kHz) via a loop antenna, providing a communication range of over 500 meters. The wireless electronic detonator consists of a low-frequency receiving antenna, a controller, a digital electronic detonator, and a battery. After the wireless electronic detonator is buried at the bottom of the deep hole and filled with explosives, the transmitter unit transmits the low-frequency command, which triggers the explosives to trigger the blasting effect.

[0003] Wireless electronic detonators present two key challenges during use: 1) Because they are battery-powered and buried between 0 and 50 meters underground, they can only passively receive commands and cannot transmit information back to the detonator. 2) Because the geology of the area in which they operate can be complex, underground water systems or mineral deposits with high magnetic flux in mining areas can attenuate the low-frequency signal emitted by the transmitter.

[0004] Based on the above two key issues, how to provide a method for evaluating the ground penetration of wireless electronic detonators before they are buried on site, so as to avoid poor communication of individual wireless electronic detonators due to site differences. Summary of the Invention

[0005] Based on this, it is necessary to provide a ground penetration test device for wireless electronic detonators to address the above technical problems.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0019] This application is mainly used to solve the problem of evaluating the reliability of through-the-ground communication during the implementation of wireless electronic detonator projects, solve the problem that wireless electronic detonators buried in deep test holes cannot exchange data with the outside world, and solve the problem of repeated testing of experimental wireless electronic detonators buried in holes, and provide guidance for the on-site engineering implementation of wireless electronic detonators.

[0020] like Figure 1 As shown, a ground penetration test device for wireless electronic detonators includes: an above-ground portion 8 and an underground portion 4, which are connected by a reinforced optical fiber 7. The above-ground portion 8 includes: a wireless communication module 15 and an optical fiber control module 16. The wireless communication module 15 is a 433MHz frequency band radio frequency module for remote command transmission. The optical fiber control module 16 includes: a battery, a controller, and an optical fiber transceiver. The optical fiber control module is used to control signal conversion and power supply. The underground portion 4 includes: a device housing 18, an optical fiber communication unit 6, a wireless electronic detonator 5, and a communication line 11. The device housing 18 is used to withstand the pressure of the earth sealing without interfering with low-frequency signals. The optical fiber communication unit 6 includes an optical fiber transceiver, a controller, and a battery. The first end of the optical communication unit 6 is connected to the optical control module 16, and the second end of the optical communication unit 6 is connected to the debugging interface of the wireless electronic detonator 5 through the communication line 11; wherein, the wireless electronic detonator 5 includes: a wireless controller 13, a low-frequency receiving antenna 14 and a test detonator 12, the wireless controller 13 is used to drive the test detonator 12 to detonate and / or receive low-frequency instructions through the low-frequency receiving antenna, the wireless controller 13 receives external signals through the low-frequency receiving antenna and converts them into signal power, receives noise signals when there is no external signal, and converts them into noise signal power, obtains ground penetration parameters based on the signal power and the noise signal power, and the wireless controller sends the ground penetration parameters to the ground part and the remote detonator 1 through the optical fiber communication unit.

[0021] Specifically, the initiator 1 of the through-the-earth performance testing device for wireless electronic detonator has a wireless antenna that can drive a low-frequency antenna 3 to send low-frequency signals to the working area 10 of the wireless electronic detonator. In engineering, deep holes are drilled every few meters or tens of meters in the working area 10 of the wireless electronic detonator, and wireless electronic detonators 5 and explosives are placed in the deep holes for blasting. To test whether the low-frequency coverage boundary of the wireless transmitting unit 2 covers the working area 10 of the wireless electronic detonator, a deep hole is drilled at the edge of the working area 10 of the wireless electronic detonator, and the underground part 4 of the through-the-earth performance testing device is placed at the bottom of the deep hole, and the enhanced optical fiber 7 is connected with the above-ground part 8 of the wireless through-the-earth performance testing device. The underground part of the wireless electronic detonator through-the-earth performance testing device amplification effect 9 is shown, which includes a wireless electronic detonator 5 and an optical fiber communication unit 4, wherein the wireless electronic detonator 5 can be selected for safety by a common electronic detonator for testing, and the wireless electronic detonator 5 can detect the signal strength and other information of the low-frequency signal, and transmit the test results to the optical fiber communication unit 6 to convert the optical fiber signal to the above-ground part 8, and the test results are transmitted to the initiator through the wireless module of the above-ground part 8 of the wireless through-the-earth performance testing device.

[0022] As Figure 2 shown, specifically, the block diagram of the wireless electronic detonator through-the-earth performance testing device. The wireless electronic detonator through-the-earth testing device includes an above-ground part 8 and an underground part 4, and the two parts are connected by an enhanced optical fiber 7. The above-ground part 8 of the wireless electronic detonator through-the-earth performance testing device includes a wireless communication module 15 and an optical fiber control module 16. The wireless control module 15 can be a 433MHz frequency band radio frequency module, such as a LORA module, etc. The optical fiber control module 16 is composed of a battery, a controller, and an optical fiber transceiver, and can also have an external display to display the test results on site. The underground part 4 of the wireless electronic detonator through-the-earth performance testing device includes a device shell 18, an optical fiber communication unit 6, a wireless electronic detonator 5, and a communication line 11. The device shell is made of an insulator with high strength and no magnetic guide characteristics, so that it can withstand the earth pressure without deformation and affect the low-frequency test, for example: glass steel material. The optical fiber communication unit 6 communicates with the optical fiber control module 16 of the above-ground part 8, and the underground part 4 includes an optical fiber transceiver, a controller, and a battery, which can be connected to the debugging interface of the wireless electronic detonator 5 through the communication line 11 for communication. The wireless electronic detonator includes a wireless controller 13, three sets of low-frequency receiving antennas 14, and a common detonator 12. The wireless electronic detonator controller 13 has the functions of driving the common detonator 12 to detonate and receiving low-frequency commands through the antenna 14. For safety, the wireless electronic detonator for testing can not install the common detonator to avoid accidental triggering during operation.

[0023] It should be noted that during the test, the wireless electronic detonator controller 13 receives external signals through the low-frequency receiving antenna 14, evaluates the signal strength, and converts it into signal power. For example, the test signal power of -60dbm represents the attenuation degree of the signal underground.

[0024] The wireless electronic detonator controller 13 receives the noise signal when there is no external signal through the low-frequency receiving antenna 14, evaluates the strength of the noise signal, and converts it into signal power. For example, the test noise signal power of -70dBm represents the noise level of the signal underground.

[0025] The wireless electronic detonator controller 13 will upload the test results step by step until they are sent to the above-ground part 8 of the device and the remote initiator 1. The initiator can calculate whether it can reliably cover the area based on the test data and the location of the ground penetration performance test device and formulate improvement measures.

[0026] like Figure 3 Specifically, the figure shows a schematic diagram of the external structure of the underground portion of the wireless electronic detonator ground penetration performance test device, including a reinforcing optical fiber 7, a bearing 17, a high-strength insulating device housing 18, and threads 19. To ensure that the wireless electronic detonator ground penetration performance test device can be used multiple times, it must be removed from the test hole to the surface after use and testing. The reinforcing optical fiber 7, woven from optical fiber and nylon, is used for communication and for dragging from the surface. While ensuring strength, the bearing 17 facilitates rotation during removal of the underground device, reducing tension. The outer side of the bearing 17 is fixed to the device housing 18, while the inner side of the bearing 17 is fixed to the optical fiber 7 and the interior. As the optical fiber is dragged, the device housing 18 rotates while the reinforcing optical fiber 7 and the internal structure remain relatively stationary.

[0027] In this embodiment, the device housing 18 is used to protect the internal structure from being damaged by the external sealing soil without affecting the normal measurement of the signal. The device housing 18 has a thread 19 on the outside, which cooperates with the bearing 17 to drag the spiral upward with less dragging force.

[0028] In this embodiment, the present application provides a ground penetration test device for wireless electronic detonators. The device is connected to the wireless electronic detonator through a wired underground connection and uses reinforced optical fiber for data upload. Buried underground, the device can test parameters such as the coverage distance and underground attenuation of low-frequency signals. After being buried underground, the ground penetration test device and the wireless electronic detonator communicate using wired optical fiber. The communication line lacks conductors, preventing induction of the conductors by the low-frequency signal and affecting the test results. The outer surface of the device housing of the underground portion 4 of the wireless electronic detonator ground penetration test device has threads 19 connected to a reinforced nylon rope, making it easy to pull the device out of a deep hole for multiple uses. The ground penetration test device for wireless electronic detonators includes an above-ground portion 8 and an underground portion 4. After the above-ground portion 8 obtains the test results from the underground portion 4 via the reinforced optical fiber 7, it communicates with the initiator via a wireless module, displaying the evaluation results on the initiator.

[0029] like Figure 4 As shown, a method for testing the earth penetration of wireless electronic detonators comprises: Set up the low-frequency transmitting unit at the test site to be tested; Obtain blasting parameters at the test site, including the size of the wireless electronic detonator's working area and the depth, number, and location of the explosive holes; According to the location of the low-frequency transmitting unit and the blasting parameters, a ground penetration test device for burying wireless electronic detonators in the test hole is selected; Obtain the ground penetration parameters of each test hole through the detonator; Adjust the low-frequency signal according to the ground penetration parameter.

[0030] In one embodiment, adjusting the low-frequency signal according to the ground penetration parameter includes: If the obtained ground penetration parameters of each test hole are less than the threshold, the power of the power amplifier inside the low-frequency transmitting unit is adjusted; If the difference between the power signals of the above-ground test and the underground test of each test hole is greater than a threshold, the carrier frequency of the modulation part of the low-frequency transmitting unit is changed; If the noise level at the site to be tested is greater than the threshold, the transmission power of the low-frequency transmitting unit is increased, thereby increasing the signal-to-noise ratio of the low-frequency signal.

[0031] Specifically, before the wireless electronic detonator is implemented on site, it is necessary to conduct an on-site ground penetration performance assessment. The main aspects of the assessment are as follows: 1) Evaluate whether the transmitting antenna direction of the low-frequency transmitting unit is at the optimal angle θ: The low-frequency transmitting unit's antenna is composed of multiple turns of coils. The low-frequency electromagnetic signal it generates is directional. To ensure maximum transmission intensity in the direction of the detonation area, the antenna's orientation must be adjusted. Furthermore, due to the influence of geomagnetic currents or mountainous terrain at the site, the actual antenna's strongest transmission direction may deviate from the theoretical transmission direction. Therefore, the simplest and most effective method is to conduct an on-site antenna orientation test to determine the antenna's actual orientation.

[0032] 2) Evaluate the boundary L between the low-frequency transmitting unit and the wireless electronic detonator working area: The low-frequency signal emitted by the low-frequency transmitting unit will be attenuated during the process of space radiation and penetration into the ground. The longer the distance and the deeper the deep hole, the more serious the signal attenuation will be. Theoretically, the spatial attenuation is proportional to the cube of the distance. Therefore, it is necessary to determine the coverage range of the transmitting unit and retain an appropriate margin to ensure that the wireless electronic detonator can receive a low-frequency command signal of sufficient strength.

[0033] 3) Evaluate the signal attenuation μ of the material in which the wireless electronic detonator is buried: The underground environment of wireless electronic detonators is complex. The attenuation of low-frequency signals transmitted through dry sand and moist soil varies significantly. The attenuation also varies significantly between ordinary sand and various metal ores. Measuring and calculating the attenuation of underground materials is nearly impossible for on-site personnel. To evaluate ground penetration performance, the most effective method is to directly measure signal attenuation.

[0034] After the on-site evaluation of the wireless electronic detonators is completed, the on-site staff can evaluate the reliability of the wireless electronic detonators and make subsequent adjustments or draw corresponding conclusions, as follows: 1) Adjust the optimal antenna orientation based on the test results; 2) Reduce the power of the wireless transmitter unit according to the transmission coverage distance of the wireless transmitter unit and the area where the wireless electronic detonator is working on site; 3) Depending on the attenuation level of the material in the working area of ​​the wireless electronic detonator, the power of the transmitting unit can be increased or the low-frequency frequency of the transmitting unit can be adjusted.

[0035] Since wireless electronic detonators are battery-powered and cannot respond to low-frequency command signals, a wireless electronic detonator ground penetration test device is required to complete on-site testing.

[0036] like Figure 4 The figure shows a flow chart of the method for testing the ground penetration performance of wireless electronic detonators. Step 1 20: Set up the low-frequency transmitting unit 2 and low-frequency transmitting antenna 3 at the test site. To maintain a safe distance between the transmitting unit and the blasting area, they are generally set up about 200 meters away from the blasting area.

[0037] The second step, step 21, is to obtain blasting parameters for the test site. These parameters include the size of the wireless electronic detonator's operating area and the depth, number, and location of the explosive holes. These blasting parameters are typically designed and determined by blasting engineers based on rock mechanics and the type of explosive.

[0038] In step 22, to evaluate the coverage of the wireless detonator's operating area 10 by the low-frequency transmitter unit 2 and antenna 3, several points within the operating area are selected for both above-ground and underground coverage measurements, as well as ground penetration performance. Typically, three to four points within the operating area, those furthest from the antenna, are selected. The noise and signal strength above ground are measured in the deep hole. The wireless detonator ground penetration performance test device is then buried within the deep hole, filled with soil, and the noise and signal strength below the deep hole are measured.

[0039] In the fourth step 23 , the ground penetration test device for wireless electronic detonators uploads the test data of each position to the initiator 1 , and the initiator evaluates the coverage of the wireless detonator working area 10 based on the positions and signal strengths of the multiple holes.

[0040] Step 5 24: Adjust the direction of the antenna based on the evaluation results. For example, if the power of the signal on both sides of the antenna is larger on one side and smaller on the other side, the direction of the antenna can be adjusted. If the received signal power of each test point is generally small, the power of the power amplifier inside the transmitting unit 2 can be adjusted; If the power signal difference between the above-ground test and the underground test at the test point is large, and there is water or high metal ore content underground in the working area, the ground penetration effect is poor. In this case, the carrier frequency of the modulation part of the transmitting unit 2 can be changed. For example, the 100kHz signal carrier can be reduced to 60kHz. Although the frequency reduction will sacrifice some communication speed, the ground penetration effect is improved. If the overall noise level in the area is too high, the staff can try to reduce the noise level nearby based on the type of noise, such as confirming whether there is any construction machinery nearby. They can also increase the transmission power of the transmitting unit 2 to increase the signal-to-noise ratio of the low-frequency signal.

[0041] After adjusting the above parameters, the detonator 1 can be operated to send instructions back to the launch unit 2 and the ground penetration performance test device at each point, and retest and reanalyze and evaluate to verify whether the effect of the adjustment is improved.

[0042] In step 6 25 , after completing the above tests and corresponding optimization adjustments, the underground testing device can be pulled out of the deep hole through the high-strength optical fiber 7 .

[0043] The seventh step 26 is to complete the area calibration of the wireless detonator working area 10, and the wireless detonator through-the-earth performance test is completed. Subsequent blasting engineers can re-evaluate the completed area to drill holes, place wireless detonators, load explosives, and perform normal blasting operations.

[0044] It should be understood that, although Figure 4 The steps in the flowchart of the method are shown in sequence according to the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other orders. Moreover, Figure 4 At least part of the steps in the method can include multiple sub-steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily sequential, but can be executed in rotation or alternation with at least part of other steps or sub-steps or stages of other steps.
