Electronic detonator safety initiation method

Abstract

The application discloses a safety detonation method of electronic detonator, which comprises the following steps: using a UAV to perform safety identification and confirmation on a blasting danger area; if the UAV finds that the blasting danger area has personnel or live animals, a driving-off program is started; after a detonation controller completes network inspection of the electronic detonator and transmits a delay command of the electronic detonator, the UAV sends a safety confirmation instruction to a detonator; after the detonation controller receives the safety confirmation instruction, the detonation controller is unlocked and charges and detonates the electronic detonator; after the UAV sends the safety confirmation instruction, the blasting danger area is still monitored to determine whether to perform a blasting interruption operation; and the core of the method is that the detonation controller can be unlocked and charges and detonates the electronic detonator only when it is confirmed that the blasting danger area is safe, so that the deficiency of artificial safety confirmation is made up, and the possibility that a blasting safety accident occurs due to human negligence or the difficulty of confirming safety of personnel in a complex scene is prevented.

Description

Technical Field

[0001] This invention relates to the field of civil explosives technology, specifically to a safe detonation method for electronic detonators. Background Technology

[0002] The "Regulations on the Administration of Civil Explosives of the People's Republic of China" stipulate that blasting operations must comply with blasting safety operating procedures. A designated person must be in charge of command; warning posts and signs must be set up at the boundaries of the danger zone; a signal must be given before blasting, and blasting is only permitted after all personnel in the danger zone have evacuated to a safe location.

[0003] During actual blasting operations, dedicated safety officers supervise and control the blasting danger zone. Before the blasting signal is issued, the safety officer will visually check whether there are any people in the danger zone, use loudspeaker equipment to warn people in the danger zone, and set up video equipment to monitor the danger zone.

[0004] After the blaster completes the blasting operation and prepares for detonation, he waits for the safety officer to confirm the safety of the blasting site. Upon receiving the safety officer's instructions, the blaster will detonate the explosives.

[0005] Numerous patents have provided solutions for the initiation methods and devices of electronic detonators. However, these solutions only consider the control of the detonator during the initiation process and do not organically integrate the safety control at the blasting site. This results in a separation between the blaster's operation and the safety officer's on-site safety confirmation during actual operations, which can easily lead to safety accidents. Summary of the Invention

[0006] The technical problem this invention aims to solve is to overcome existing deficiencies and provide a safe detonation method for electronic detonators. This method organically combines on-site safety management of blasting operations with the detonation process of electronic detonators. A drone is used to survey the safety situation at the site, and the survey results are fed back to the detonation controller. The detonation controller can only unlock and charge the electronic detonator and detonate it after confirming that the blasting hazard area is safe. This method compensates for the inadequacy of human safety confirmation and prevents the possibility of blasting safety accidents caused by human negligence or in complex scenarios where personnel cannot confirm safety. It can effectively solve the problems in the background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a safe detonation method for an electronic detonator, comprising the following steps:

[0008] Step 1: Use drones to safely identify and confirm the blasting hazard area;

[0009] Step 2: If the drone detects people or live animals in the blasting danger zone, it will automatically initiate the removal procedure.

[0010] Step 3: After the detonator completes the electronic detonator network check and transmits the electronic detonator delay command, if the drone passes the safety identification, the drone will send a safety confirmation command to the detonator. After receiving the safety confirmation command, the detonator will unlock and charge and detonate the electronic detonator.

[0011] Step 4: After the drone sends a safety confirmation command, it continues to monitor the blasting danger zone to determine whether to interrupt the blasting operation.

[0012] Specifically, the safety identification method in step one is a thermal imaging identification method, which uses thermal imaging sensors to perceive the heat distribution information of the blasting hazard area, and then detects whether there are active people or animals in the blasting hazard area.

[0013] Specifically, the safety identification method in step one is an image recognition method, which uses a high-definition camera in conjunction with relevant algorithms to detect whether there are active people or animals, as well as stationary human and animal silhouettes in the blasting hazard area.

[0014] Specifically, the expulsion procedure in step two is a voice expulsion procedure, in which the speaker on the drone plays a pre-set expulsion sound effect to remind or urge people or animals in the blasting danger zone to stay away from the area.

[0015] Specifically, the expulsion procedure in step two is a laser expulsion procedure, in which the laser device carried by the drone sends laser warning information to the area where people or live animals appear, reminding and expelling people or live animals from the area.

[0016] Specifically, the expulsion procedure in step two is an alarm light expulsion procedure, in which the alarm light on the drone works in conjunction with the speaker to issue an alarm reminder and expel people or live animals from the area.

[0017] Specifically, the activation scenario for the blasting interruption operation in step four is that before the detonation is completed, the drone detects that personnel or other live animals have entered the danger zone. The drone immediately sends a blasting pause command to the detonation controller. After receiving the blasting pause command, the detonation controller immediately executes commands such as pausing blasting and discharging electronic detonators. After the safety time interval is completed, the blaster needs to confirm again whether to continue blasting. After confirming blasting, the detonation controller enters a state of waiting to receive safety confirmation commands from the drone.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This safe detonation method for electronic detonators organically combines the safety management of the blasting operation site with the detonation process of the electronic detonator. The method uses a drone to investigate the safety situation at the site and feeds back the investigation results to the detonation controller. The detonation controller can only unlock and charge and detonate the electronic detonator after confirming that the blasting danger zone is safe. This method makes up for the lack of human safety confirmation and prevents the possibility of blasting safety accidents caused by human negligence or difficulty in confirming safety in complex scenarios.

[0019] This method establishes a precise communication channel between blasters and safety officers at the blasting site through the communication system between the drone and the detonator, avoiding the possibility of blasting safety accidents caused by inaccurate verbal safety confirmations or misinterpretation of safety confirmation instructions.

[0020] The thermal imaging identification method used in this method has good penetration and is not affected by weather. It plays a particularly prominent role in safety confirmation in complex scenes and blasting scenes with poor visibility. It can greatly make up for the current lack of personnel-led safety confirmation and prevent blasting safety accidents.

[0021] This method uses drones to record the on-site blasting process and links a detonation controller to manage the detonation process, thereby achieving more precise and safer control over the use of civilian explosives in my country. Attached Figure Description

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-4 This invention provides a technical solution: a safe detonation method for electronic detonators, comprising the following steps:

[0028] Step 1: Use a drone to identify and confirm the safety of the blasting hazard area. The identification method is thermal imaging. The thermal imaging sensor senses the heat distribution information of the blasting hazard area, and then detects whether there are active people or animals in the blasting hazard area. The thermal imaging identification method is as follows: quickly search for heat sources. If there is no heat source, the safety is directly confirmed. If there is a heat source, the drone randomly selects one of the identified heat sources for close-range image recognition. If it finds a person or a live animal, the removal procedure is initiated. If the image recognition does not find a person or a live animal, a second confirmation by personnel is required. After completing one personnel confirmation, the next heat source confirmation is carried out. Thermal imaging identification has good penetration and is not affected by weather. It plays a particularly prominent role in safety confirmation in complex scenes and blasting scenes with poor visibility. It can greatly make up for the current shortcomings of personnel autonomous safety confirmation and prevent blasting safety accidents. Image recognition method can also be used. High-definition cameras and related algorithms are used to detect whether there are active people or animals, as well as stationary human and animal outlines in the blasting hazard area.

[0029] Step Two: If the drone detects people or live animals in the blasting hazard area, it will autonomously initiate a evacuation procedure. The evacuation procedure can be one or more of the following: a voice evacuation procedure, a laser evacuation procedure, or an alarm light evacuation procedure. The drone will play pre-set evacuation sound effects through speakers on board or off-site, or through alarm lights, to remind or urge people or animals in the blasting hazard area to move away from the area. Alternatively, the drone can send laser warning messages to the area where people or live animals are present through laser equipment to remind and evacuate people or live animals from the area.

[0030] Step 3: After the detonator completes the electronic detonator network check and transmits the electronic detonator delay command, if the drone passes the safety identification, the drone will send a safety confirmation command to the detonator. After receiving the safety confirmation command, the detonator will unlock and charge and detonate the electronic detonator.

[0031] Step Four: After the drone sends the safety confirmation command, it continues to monitor the blasting danger zone to determine whether to interrupt the blasting operation. The blasting interruption operation is initiated when the drone detects personnel or other live animals entering the danger zone before the detonation is completed. The drone immediately sends a detonation pause command to the detonation controller. Upon receiving the detonation pause command, the detonation controller immediately executes commands such as pausing detonation and discharging the electronic detonator. After the safety time interval is completed, the blaster needs to confirm again whether to continue the detonation. After confirming the detonation, the detonation controller enters the state of waiting to receive the drone's safety confirmation command and repeats Step One. After receiving the safety confirmation command, the detonation controller starts the charging and detonation procedures for the electronic detonator to complete the detonation.
