Description

Technical Field

[0001] This utility model relates to the field of electronic detonator blasting technology, specifically to an intelligent wireless blasting system for complex and multi-scenario working conditions. Background Technology

[0002] In blasting operations, traditional electronic detonator initiation methods typically employ wired connections. This approach suffers from drawbacks such as wiring difficulties, high costs, and low safety in complex terrain or long-distance blasting scenarios. With the widespread adoption of electronic detonators and the development of wireless communication technology, wireless initiation of electronic detonators has become possible. However, in complex environments such as mountainous areas and forests, signal obstruction, transmission distance limitations, and increasingly complex and demanding blasting operations often make direct wireless transmission insufficient to meet initiation requirements. Furthermore, the increasing complexity and scale of blasting operations necessitate remote wireless blasting systems and methods for complex conditions. These systems, combined with intelligent blasting systems and intelligent loading systems, can provide the industry with new mining thinking and unmanned mining models, contributing to the industry's development towards safer and more efficient future intelligent mines.

[0003] In related technologies, Chinese patent with publication number CN113781761B discloses a wireless detonation method and system, which is suitable for general open-air environments, but not applicable to some complex and large-scale environments, and also needs to be integrated with a blasting design system. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an intelligent wireless blasting system for complex and multi-scenario working conditions, which can solve the problems of unreliable initiation transmission, small scale of wireless initiation, and limited application range.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model provides an intelligent wireless blasting system for complex multi-scenario working conditions, comprising: a wireless detonation remote controller, a drone, a first relay transmitter, at least one second relay transmitter, and at least one set of electronic detonators; the wireless detonation remote controller is wirelessly connected to the first relay transmitter, the first relay transmitter and the second relay transmitter are wirelessly connected, the second relay transmitter and the electronic detonators are wiredly connected, the first relay transmitter is mounted on the drone, and the second relay transmitter is located on the ground.

[0007] By adopting the above technical solution, when remote wireless blasting is carried out under complex and large-scale conditions, if there is only one blasting zone, after the electronic detonators in the blasting zone are loaded with explosives, the on-site operator uses a wireless detonation remote controller to scan the identification information on the leads of the electronic detonators in the blasting zone to complete the registration code, so as to control the detonation delay time of each electronic detonator; at the same time, the electronic detonators are activated and put into working mode, and the second relay transmitter is connected to the electronic detonator and the power switch of the second relay transmitter is turned on. If there are multiple blasting zones, the leads of the electronic detonators in each blasting zone also need to be connected in parallel to form a network. Afterwards, personnel in the blasting zone are evacuated to a safe zone, and the drone flies to a safe position above the blasting and activates functions such as perimeter warning of the blasting zone; the on-site operator at the detonation point uses the wireless detonation remote controller to wirelessly transmit the detonation setting data, such as network detection, charging, and detonation commands, to the first relay transmitter. After receiving the detonation setting data, the first relay transmitter transmits signals such as network detection, charging, and detonation commands to the second relay transmitter connected to the electronic detonator network within the blast zone. The electronic detonators within the blast zone receive the detonation setting data through the second relay transmitter, perform zonal network detection and charging operations according to the data, and feed the results back to the wireless detonation remote controller via the first relay transmitter on the drone. Finally, the on-site operator controls the wireless detonation remote controller to issue a detonation command, which is transmitted sequentially through the first and second relay transmitters to control the electronic detonators to detonate.

[0008] In the above process, by using a drone to carry the first relay transmitter and communicate with the second relay transmitter on the ground, the effective transmission and coverage of wireless signals can be achieved. This effectively solves the problems of laying detonation lines and the difficulty of manual supervision in extremely complex environments. It can reduce the number of operation procedures, expand the scale of blasting, improve the safety and reliability of blasting construction, and meet the intelligent blasting needs of extreme and complex environments such as deep water, underground mines, and avalanches.

[0009] Optionally, the electronic detonator has a built-in electronic control module, which includes a control unit, a signal transceiver unit, and a power supply unit. The control unit is connected to the signal transceiver unit and the power supply unit, respectively, and is in contact with the ignition charge. The signal transceiver unit is wiredly connected via a double-strand detonating wire and a second relay transmitter.

[0010] By adopting the above technical solution, the control unit can ignite the ignition powder in the electronic detonator, and can also perform electronic detonator networking, charging control, and control the detonation of the electronic detonator after receiving the signal from the second relay transmitter; the signal transceiver unit can receive and send signals; and the power supply unit can supply power to the control unit and the signal transceiver unit.

[0011] Optionally, the drone has a camera, which may be an infrared camera and / or an image recognition camera.

[0012] By adopting the above technical solutions, drones can achieve functions such as safe flight, perimeter surveillance of blasting zones, intelligent early warning and expulsion, and full-process monitoring of blasting effects through cameras.

[0013] Optionally, the wireless detonation remote controller is wirelessly connected to a blasting design platform.

[0014] By adopting the above technical solution, a blasting design scheme can be generated through the blasting design platform, and on-site operators can download the blasting design scheme through wireless communication with the blasting design platform via a wireless detonation remote controller.

[0015] Optionally, the UAV is wirelessly connected to a security monitoring platform, and the security monitoring platform is wirelessly connected to a first relay transmitter.

[0016] By adopting the above technical solution, drones can send real-time information acquired by cameras to a safety monitoring platform, thereby achieving functions such as safe flight, perimeter surveillance of the blasting area, intelligent early warning and deterrence, and full-process monitoring of blasting effects. The safety monitoring platform can also acquire real-time blasting information.

[0017] In summary, this utility model has at least the following beneficial technical effects:

[0018] By using drones equipped with relay transmitters, effective transmission and coverage of wireless signals can be achieved, effectively solving problems such as the need to lay detonation lines and the difficulty of manual supervision in extremely complex environments. This reduces the number of operational procedures, expands the scale of blasting, improves the safety and reliability of blasting operations, and meets the intelligent blasting needs in extremely complex environments such as deep water, underground mines, and avalanches.

[0023] This embodiment provides an intelligent wireless blasting system for complex and multi-scenario working conditions.

[0024] refer to Figure 1 A smart wireless blasting system for complex multi-scenario working conditions includes: a wireless detonation remote controller 1, a drone 2, a first relay transmitter 3, at least one second relay transmitter 4, and at least one set of electronic detonators 5.

[0025] The wireless detonator 1 is wirelessly connected to the first relay transmitter 3, and the first relay transmitter 3 is wirelessly connected to the second relay transmitter 4. The second relay transmitter 4 is wiredly connected to the electronic detonator 5. The first relay transmitter 3 is mounted on the drone 2, and the second relay transmitter 4 is located on the ground. Both the first relay transmitter 3 and the second relay transmitter 4 have wireless transceivers to enable long-distance wireless signal transmission between the electronic detonator 5 and the wireless detonator 1.

[0026] The drone 2 has stable flight capabilities and a long endurance. Its flight path can be controlled by a remote controller or pre-programmed using a path planning algorithm. The drone 2 is equipped with a camera 21, enabling full-process monitoring and early warning / deterrence during blasting operations. The camera 21 can be an infrared camera 21 or an image recognition camera 21.

[0027] The electronic detonator 5, when processed with packaged explosives or detonators, can form a detonating charge. The electronic detonator 5 has a built-in electronic control module 51, which connects to the electronic detonator 5 only when detonation is required. The electronic control module 51 includes a control unit 511, a signal transceiver unit 512, and a power supply unit 513. The control unit 511 is used to ignite the ignition charge inside the electronic detonator 5, and is also used for networking and charging control of the electronic detonators 5; the signal transceiver unit 512 is used to receive and send signals; the power supply unit 513 is used to supply power to the control unit 511 and the signal transceiver unit 512. The control unit 511 is connected to the signal transceiver unit 512 and the power supply unit 513 respectively, and is in contact with the ignition charge; the signal transceiver unit 512 is wiredly connected via a double-strand detonating wire and a second relay transmitter 4.

[0028] The wireless detonator remote controller 1 can remotely control the electronic detonator 5 to perform network detection, charging, and setting detonation data. After the electronic detonator 5 completes the network detection, charging, and detonation data setting, it can transmit all data to the wireless detonator remote controller 1, after which remote wireless detonation can be carried out. Among them, after receiving the detonation signal, the electronic control module 51 can perform remote wireless detonation either instantaneously or with a precise delayed detonation.

[0029] When there is one blasting zone, a second relay transmitter 4 and a set of electronic detonators 5 are used, and there are multiple sets of electronic detonators 5. If there are multiple blasting zones, multiple second relay transmitters 4 and multiple sets of electronic detonators 5 are used. Each blasting zone has one second relay transmitter 4 and a set of electronic detonators 5, thereby realizing two-way communication and command transmission with the wireless detonation remote controller 1, which meets the requirements of large-scale blasting network.

[0030] refer to Figure 1 The wireless detonator remote controller 1 is also wirelessly connected to the blasting design platform 6. The wireless detonator remote controller 1 can obtain the blasting design plan in advance through the blasting design platform 6. The wireless detonator remote controller 1 scans or identifies the identification information of the electronic detonator 5 on site through manual positioning, automatic borehole positioning and other methods, such as QR code, barcode, RFID and other identification codes, to achieve matching of detonator borehole position, delay time and detonator identification information, thereby completing the efficient and safe registration coding of the electronic detonator 5.

[0031] The drone 2 is also wirelessly connected to the safety monitoring platform 7. The drone 2 can send real-time information acquired by the camera 21 to the safety monitoring platform 7, thereby realizing functions such as safe flight, perimeter warning of the blasting area, intelligent early warning and expulsion, and full-process monitoring of the blasting effect. The safety monitoring platform 7 is also wirelessly connected to the first relay transmitter 3 to realize real-time information acquisition of the blasting.

[0032] The blasting platform and the safety monitoring platform 7 can be devices such as mobile phones, tablets, PDAs, laptops, and desktop computers. They can be two separate devices or a single device.

[0033] The implementation principle of an intelligent wireless blasting system for complex multi-scenario working conditions according to an embodiment of this application is as follows:

[0034] When remote wireless blasting is carried out under complex and large-scale conditions, the blasting design scheme is first generated through the blasting design platform 6. The on-site operator downloads the blasting design scheme through wireless communication between the wireless detonation remote controller 1 and the blasting design platform 6, or the blasting design scheme is automatically set on-site.

[0035] Then, when there is only one blast zone, after the electronic detonators 5 in the blast zone are loaded with explosives, the on-site operator uses the wireless detonation remote controller 1 to scan the identification information on the leads of the electronic detonators 5 in the blast zone to complete the registration code, so as to control the detonation delay time of each electronic detonator 5; at the same time, the leads of the electronic detonators 5 are connected to the electronic control module 51, and the power switch of the electronic control module 51 is turned on to enter the working mode. Finally, the second relay transmitter 4 is connected to the electronic control module 51 through the detonation line, and the power switch of the second relay transmitter 4 is turned on. If there are multiple blast zones, the leads of the electronic detonators 5 in each blast zone also need to be connected in parallel to form a network.

[0036] Afterwards, personnel within the blast zone were evacuated to a safe area. Drone 2 flew to a safe position above the blasting site and activated functions such as perimeter surveillance. At the detonation point, on-site operators wirelessly transmitted detonation setting data, including network detection, charging, and detonation commands, to the first relay transmitter 3 via the wireless detonator remote controller 1. Upon receiving the detonation setting data, the first relay transmitter 3 transmitted the network detection, charging, and detonation command signals to the second relay transmitter 4, which was connected to the network of electronic detonators 5 within the blast zone. The electronic detonators 5 within the blast zone received the detonation setting data via the second relay transmitter 4 and performed zonal network detection and charging operations accordingly. The results were then fed back to the wireless detonator remote controller 1 and the safety monitoring platform 7 via the first relay transmitter 3 on Drone 2. Finally, the on-site operators controlled the wireless detonator remote controller 1 to issue a detonation command, which was transmitted sequentially through the first relay transmitter 3 and the second relay transmitter 4 to detonate the electronic detonators 5.

[0037] In the above process, by using a relay transmitter on the drone 2, the effective transmission and coverage of wireless signals can be achieved, effectively solving the problems of laying detonation lines and the difficulty of manual supervision in extremely complex environments. It can reduce the number of operation procedures, expand the scale of blasting, improve the safety and reliability of blasting construction, and meet the intelligent blasting needs of extreme and complex environments such as deep water, underground, and avalanches.

[0038] The above description of the embodiments is only used to provide a detailed introduction to the technical solution of this utility model. However, the description of the above embodiments is only for the purpose of helping to understand this utility model and should not be construed as a limitation of this utility model. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model should be included within the protection scope of this utility model.
