Description

Technical Field

[0001] The present invention relates to the technical field of electronic detonator blasting, and particularly relates to an intelligent wireless blasting system and method for complex multi-scenarios. Background Art

[0002] In blasting engineering, the traditional initiation method of electronic detonators usually adopts wired connection. This method has problems such as difficult wiring, high cost, and low safety in complex terrain or long-distance initiation scenarios. With the full promotion and application of electronic detonators and the development of wireless communication technology, wireless initiation of electronic detonators has become possible. However, in some complex environments, such as mountainous areas and forests, due to signal occlusion and transmission distance limitations, as well as the increasing complexity of blasting docking and higher scale requirements, directly adopting wireless transmission often fails to meet the initiation requirements. At the same time, the blasting docking is becoming more and more complex and the scale requirements are getting higher and higher. There is an urgent need for a remote wireless blasting system and method under complex conditions, combined with an intelligent blasting system, an intelligent loading system, etc., to provide a new mining thinking mode and unmanned mine mode for the industry, which is conducive to the development of the industry towards a safer and more efficient future intelligent mine.

[0003] In the related art, a Chinese patent with the publication number CN113781761B discloses a wireless initiation method and system, which meets the application scenarios with better general open-air environments, but is not applicable in some complex environments and large-scale environments, and also needs to be docked with a blasting design system. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an intelligent wireless blasting system and method for complex multi-scenarios, which can solve the problems of unreliable current initiation transmission, small scale of wireless initiation, and limited application range.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] In a first aspect, the present invention provides an intelligent wireless blasting system for complex multi-scenarios, including: a wireless initiation remote controller, a drone, a first relay transmitter, at least one second relay transmitter, and at least one group of electronic detonators; the wireless initiation remote controller is wirelessly communicatively connected to the first relay transmitter, the first relay transmitter and the second relay transmitter are wirelessly communicatively connected, the second relay transmitter and the electronic detonators are wired communicatively connected, the first relay transmitter is installed on the drone, and the second relay transmitter is arranged on the ground.

[0007] By adopting the above technical solution, when remotely wireless blasting is carried out under complex large-scale conditions, if there is only one blasting area, after the electronic detonators in the blasting area are loaded and tamped, the on-site operator holds the wireless detonator remote control to scan the identity information on the leg wires of the electronic detonators in the blasting area to complete the registration coding, so as to control the detonation delay time of each electronic detonator; at the same time, enable the electronic detonators to enter the working mode, and connect the second relay transmitter to the electronic detonators and turn on the power switch of the second relay transmitter. If there are multiple blasting areas, the leg wires of the electronic detonators in each blast area need to be connected in parallel to form a network. After that, the personnel in the blasting area are evacuated to the safe area, and the unmanned aerial vehicle (UAV) flies to a safe position above the blasting area and activates functions such as perimeter warning of the blasting area; the on-site operator wirelessly transmits and sends detonation setting data such as network detection, charging, and detonation commands to the first relay transmitter through the wireless detonator remote control at the detonation point. 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 network of electronic detonators in the blasting area; after the electronic detonators in the blasting area receive the detonation setting data through the second relay transmitter, they perform operations such as network detection and charging in the partitioned network according to the detonation setting data, and feedback the results to the wireless detonator remote control through the first relay transmitter on the UAV. Finally, the on-site operator controls the wireless detonator remote control to issue a detonation command, and the detonation command sequentially passes through the first relay transmitter and the second relay transmitter to control the electronic detonators to detonate.

[0008] In the above process, by carrying the first relay transmitter on the UAV and communicating with the second relay transmitter on the ground, effective transmission and coverage of wireless signals can be achieved, effectively solving problems such as the need to lay detonation wires and the difficulty of manual supervision in extremely complex environments, reducing the operation procedures, expanding the scale of blasting, improving the safety and reliability of blasting construction, and meeting the intelligent blasting requirements in extremely complex environments such as deep water, underground, and avalanche.

[0009] Optionally, the electronic detonator is internally provided with an electronic control module, and the electronic control module includes a control unit, a signal transceiver unit, and a power supply unit; the control unit is respectively connected to the signal transceiver unit and the power supply unit, and is in contact with the ignition charge; the signal transceiver unit is in wired communication connection with the second relay transmitter through a two-strand detonator wire.

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

[0011] Optionally, the UAV is equipped with a camera, and the camera can be an infrared camera and / or an image recognition camera.

[0012] By adopting the above technical solution, the drone can realize functions such as safe flight, perimeter warning of the blasting area, intelligent early warning and driving away, and full-process detection of blasting effects through the camera.

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

[0014] By adopting the above technical solution, a blasting design plan can be generated through the blasting design platform, and on-site operators can wirelessly communicate with the blasting design platform through the wireless detonator remote controller to download the blasting design plan.

[0015] Optionally, the drone is wirelessly communicatively connected to a safety monitoring platform, and the safety monitoring platform is wirelessly communicatively connected to a first relay transmitter.

[0016] By adopting the above technical solution, the drone can send the real-time information obtained by the camera to the safety monitoring platform, so as to realize functions such as safe flight, perimeter warning of the blasting area, intelligent early warning and driving away, and full-process detection of blasting effects. The safety monitoring platform can also obtain real-time blasting information.

[0017] In a second aspect, the present invention provides an intelligent wireless blasting method for complex multi-scenarios, which is applied to the intelligent wireless blasting system for complex multi-scenarios as described in the first aspect, and includes the following steps:

[0018] S1: Receive the detonation setting data sent by the wireless detonator remote controller, and the detonation setting data includes networking detection, charging, and detonation instructions;

[0019] S2: Send the detonation setting data to the second relay transmitter for the second relay transmitter to send the detonation setting data to the corresponding electronic control modules in each electronic detonator for detonation setting;

[0020] S3: Receive the feedback data sent back by the second relay transmitter based on the detonation setting data, and send the feedback data to the wireless detonator remote controller;

[0021] S4: Receive the detonation instruction sent by the wireless detonator remote controller;

[0022] S5: Send the detonation instruction to the second relay transmitter for the second relay transmitter to send the detonation instruction to each electronic control module to control the corresponding electronic detonators to detonate

[0023] By adopting the above technical solution, when initiating an explosion, the first relay transmitter can receive the explosion initiation setting data sent by the wireless explosion initiation remote controller and send the explosion initiation setting data to the second relay transmitter. Then, the first relay transmitter can receive the feedback data sent back by the second relay transmitter based on the explosion initiation setting data and send the feedback data to the wireless explosion initiation remote controller. Finally, the first relay transmitter can receive the explosion initiation command sent by the wireless explosion initiation remote controller and send the explosion initiation command to the second relay transmitter, thus realizing the explosion initiation. In the above process, since the second relay transmitter can be carried by a drone, the transmission distance is greatly increased, and the transmission process is not affected by the terrain, so the reliability of the explosion initiation transmission is high. And by networking, the scale of the explosion initiation can be increased, so the application range can also be effectively expanded.

[0031] An embodiment of the present invention provides an intelligent wireless blasting system for complex multi-scenarios.

[0032] Reference Figure 1 , an intelligent wireless blasting system for complex multi-scenarios, comprising: a wireless initiation 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.

[0033] The wireless initiation remote controller 1 is wirelessly communicatively connected to the first relay transmitter 3, the first relay transmitter 3 and the second relay transmitter 4 are wirelessly communicatively connected, and the second relay transmitter 4 and the electronic detonators 5 are wired communicatively connected. The first relay transmitter 3 is installed on the drone 2, and the second relay transmitter 4 is arranged on the ground. Both the first relay transmitter 3 and the second relay transmitter 4 have wireless transceiver devices for realizing long-distance wireless signal transmission between the electronic detonators 5 and the wireless initiation remote controller 1.

[0034] The drone 2 has a stable flight function and a long endurance time. The flight path of the drone 2 can be controlled by a drone 2 remote controller, or the flight path of the drone 2 can be preset by a path planning algorithm in advance. The drone 2 has a camera 21, which can realize the whole-process blasting monitoring and early warning and driving away. The camera 21 can be an infrared camera 21 and / or an image recognition camera 21.

[0035] The electronic detonator 5 can form a detonating charge package when processed with packaged explosives or primers. An electronic control module 51 is built into the electronic detonator 5, and the electronic control module 51 is connected to the electronic detonator 5 only when blasting 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 in the electronic detonator 5 and is also used for networking and charging control of the electronic detonator 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 respectively connected to the signal transceiver unit 512 and the power supply unit 513 and is in contact with the ignition charge; the signal transceiver unit 512 is connected by wire communication through a double-strand detonating wire and a second relay transmitter 4.

[0036] The wireless detonation remote controller 1 can remotely control the electronic detonator 5 to perform networking detection, charging, and setting detonation data. After the networking detection, charging, and setting of detonation data of the electronic detonator 5 are completed, each data can be transmitted to the wireless detonation remote controller 1, and then remote wireless blasting can be carried out. Among them, after the electronic control module 51 receives the detonation signal, the remote wireless blasting can be instantaneous detonation or precise delay detonation.

[0037] When there is one blasting area, one second relay transmitter 4 and a group of electronic detonators 5 are used, and a group of electronic detonators 5 is multiple. If there are multiple blasting areas, multiple second relay transmitters 4 and multiple groups of electronic detonators 5 are used. Each blasting area has one second relay transmitter 4 and a group of electronic detonators 5, so as to realize two-way communication and command transmission with the wireless detonation remote controller 1 and meet the networking requirements for large-scale blasting.

[0038] Reference Figure 1 , the wireless detonation remote controller 1 is also wirelessly connected to a blasting design platform 6. The wireless detonation remote controller 1 can obtain the blasting design plan in advance through the blasting design platform 6. The wireless detonation remote controller 1 scans or identifies the identity information of the identification codes such as two-dimensional codes, barcodes, and RFID of the on-site electronic detonators 5 through manual positioning, automatic blast hole positioning, etc., and realizes the matching of the detonator blast hole positions, delay times, and detonator identity information, so as to complete the efficient and safe registration coding of the electronic detonators 5.

[0039] The drone 2 is also wirelessly connected to a safety monitoring platform 7. The drone 2 can send the real-time information obtained by the camera 21 to the safety monitoring platform 7, so as to realize functions such as safe flight, perimeter warning of the blasting area, intelligent early warning and evacuation, and full-process detection of blasting effects. The safety monitoring platform 7 is also wirelessly connected to the first relay transmitter 3 for obtaining real-time blasting information.

[0040] Among them, the blasting platform and the safety monitoring platform 7 can be devices such as mobile phones, tablet computers, personal digital assistants, laptops, and desktop computers. They can be two separate devices or one device.

[0041] The implementation principle of an intelligent wireless blasting system for complex multi-scenarios in an embodiment of this application is as follows:

[0042] When remotely wireless blasting is realized under complex large-scale conditions, first, the blasting design platform 6 generates the blasting design plan for this time. The on-site operator downloads the blasting design plan for this time through wireless communication between the wireless initiation remote control 1 and the blasting design platform 6, or automatically sets the blasting design plan on-site.

[0043] Then, when there is only one blasting area, after the electronic detonators 5 in the blasting area complete charging and tamping, the on-site operator holds the wireless initiation remote control 1 to scan the identity information on the leg wires of the electronic detonators 5 in the blasting area to complete registration coding, so as to control the initiation delay time of each electronic detonator 5; at the same time, connect the leg wires of the electronic detonators 5 to the electronic control module 51, and turn on the power switch of the electronic control module 51 to enter the working mode. Finally, connect the second relay transmitter 4 to the electronic control module 51 through the initiation wire and turn on the power switch of the second relay transmitter 4. If there are multiple blasting areas, it is also necessary to connect the leg wires of the electronic detonators 5 in each blast area in parallel for networking.

[0044] After that, the personnel in the blasting area evacuate to the safe area, the unmanned aerial vehicle 2 flies to a safe position above the blasting area and activates functions such as perimeter warning of the blasting area; the on-site operator wirelessly transmits and sends initiation setting data such as networking detection, charging, and initiation commands to the first relay transmitter 3 at the initiation point through the wireless initiation remote control 1. After receiving the initiation setting data, the first relay transmitter 3 transmits signals such as networking detection, charging, and initiation commands to the second relay transmitter 4 connected to the networking of the electronic detonators 5 in the blasting area; after the electronic detonators 5 in the blasting area receive the initiation setting data through the second relay transmitter 4, they perform operations such as zoning networking detection and charging according to the initiation setting data, and feedback the results to the wireless initiation remote control 1 and the safety monitoring platform 7 through the first relay transmitter 3 on the unmanned aerial vehicle 2. Finally, the on-site operator controls the wireless initiation remote control 1 to issue an initiation command, and the initiation command sequentially passes through the first relay transmitter 3 and the second relay transmitter 4 to control the electronic detonators 5 to initiate.

[0045] In the above process, by carrying the relay transmitter on the unmanned aerial vehicle 2, effective transmission and coverage of wireless signals can be achieved, effectively solving problems such as the need to lay initiation wires and the high difficulty of manual supervision in extremely complex environments, reducing the number of operation processes, expanding the scale of blasting, improving the safety and reliability of blasting construction, and meeting the intelligent blasting requirements in extremely complex environments such as deep water, underground, and avalanches.

[0046] An embodiment of the present invention also provides an intelligent wireless blasting method for complex multi-scenarios.

[0048] S1: Receive the blasting setting data sent by the wireless blasting remote controller 1, and the blasting setting data includes networking detection, charging, and blasting instructions.

[0049] S2: Send the blasting setting data to the second relay transmitter 4, so that the second relay transmitter 4 sends the blasting setting data to each corresponding electronic control module 51 in each electronic detonator 5 for blasting setting.

[0051] S4: Receive the blasting instruction sent by the wireless blasting remote controller 1.

[0052] S5: Send the blasting instruction to the second relay transmitter 4, so that the second relay transmitter 4 sends the blasting instruction to each electronic control module 51 to control each corresponding electronic detonator 5 to blast.
