1. 1. The safe detonation method of the electronic detonator is characterized by comprising the following steps of: step one: the unmanned aerial vehicle is used for carrying out safety recognition and confirmation on the explosion dangerous area, the recognition method is a thermal imaging recognition method, the thermal imaging sensor is used for sensing heat distribution information of the explosion dangerous area, and then whether a movable person or animal exists in the explosion dangerous area is detected, the thermal imaging recognition method comprises the following steps of quickly carrying out heat source exploration, directly confirming safety if no heat source exists, randomly selecting one from the recognized heat sources by the unmanned aerial vehicle to carry out short-range image recognition exploration if the heat source exists, starting a driving program if the heat source exists, carrying out secondary confirmation by personnel if the personnel does not exist in the image recognition, completing confirmation of entering the next heat source by the personnel, carrying out confirmation recognition by the personnel once, having better penetrability and no influence of weather, having particularly outstanding effect on safety confirmation on complex scenes and explosion scenes with poor visibility, greatly overcoming the defect of autonomous safety confirmation of the personnel in the current stage, and preventing explosion safety accidents; If the unmanned aerial vehicle finds personnel or living animals in the explosion dangerous area, automatically starting a driving program, wherein the driving program is one or more of a voice driving program, a laser driving program and an alarm lamp driving program, and reminding or prompting people or animals in the explosion dangerous area to get away from the area through a loudspeaker carried or arranged outside the unmanned aerial vehicle or an alarm lamp playing preset driving sound effect, or sending laser prompt information to the area where the people or living animals appear through laser equipment to remind and drive away the people or living animals in the area; step three, after completing the network inspection of the electronic detonator and the downloading of the delay command of the electronic detonator, if the safety identification of the unmanned aerial vehicle passes, the unmanned aerial vehicle sends a safety confirmation command to the detonator, and the detonation controller unlocks and charges and detonates the electronic detonator after receiving the safety confirmation command; And fourthly, after the unmanned aerial vehicle sends the safety confirmation instruction, the unmanned aerial vehicle still monitors the explosion dangerous area to judge whether explosion interruption operation is carried out, the starting situation of the explosion interruption operation is that before the explosion is finished, the unmanned aerial vehicle detects personnel or other living animals to intrude into the dangerous area, the unmanned aerial vehicle immediately sends an explosion suspension instruction to the explosion controller, the explosion controller immediately executes the instructions of suspending explosion, discharging the electronic detonator and the like after receiving the explosion suspension instruction, after the explosion controller receives the explosion suspension instruction, the explosion controller needs to confirm whether the explosion is continued again after the safety time interval is finished, the explosion controller enters the state of waiting to receive the safety confirmation instruction of the unmanned aerial vehicle after confirming the explosion, and the explosion controller starts the charging and explosion procedure of the electronic detonator after receiving the safety confirmation instruction to finish the explosion.

Description

Safe detonation method of electronic detonator Technical Field The invention relates to the technical field of civil explosion, in particular to a safe detonation method of an electronic detonator. Background When the explosive management regulation for people in the republic of China prescribes blasting operation, the safety operation rules of blasting must be complied with. The method comprises the steps of taking charge of command by special persons, setting guard posts and marks at the boundary of a dangerous area, sending out signals before blasting, and starting blasting after the personnel in the dangerous area are removed to a safe place. In the actual blasting process, a special safety person monitors and controls the blasting dangerous area, and before the blasting signal is sent, the safety person can visually check whether personnel exist in the dangerous area or not, warn the dangerous area through sound amplifying equipment, monitor the dangerous area through erection of camera equipment and the like. The blaster completes the blasting site operation, prepares for detonation, waits for the safety confirmation of the blasting site by the safety personnel, and completes the detonation after receiving the safety instruction of the safety personnel. The method and equipment for detonating the electronic detonator have more patents to give solutions, but the solutions only consider the control of the detonator in the detonating process, and do not organically combine the safety control of the blasting operation site, which results in the defect that in the actual operation process, the operation of a blaster and the site safety confirmation of a safety person are separated, and the safety accident is easy to occur. Disclosure of Invention The invention aims to overcome the existing defects, and provides the electronic detonator safe detonating method, which organically combines the safety control of a blasting operation site with the detonating process of the electronic detonator, probes the safety condition of the site through an unmanned plane, feeds back the probing result to a detonating controller, and enables the detonating controller to unlock and charge and detonate the electronic detonator only under the condition of confirming the safety of a blasting dangerous area. In order to achieve the purpose, the invention provides the following technical scheme that the safe detonation method of the electronic detonator comprises the following steps: The method comprises the steps that firstly, an unmanned aerial vehicle is used for carrying out safety identification and confirmation on a blasting dangerous area; step two, if the unmanned aerial vehicle finds personnel or living animals in the blasting dangerous area, the unmanned aerial vehicle automatically starts a driving-away program; step three, after completing the network inspection of the electronic detonator and the downloading of the delay command of the electronic detonator, if the safety identification of the unmanned aerial vehicle passes, the unmanned aerial vehicle sends a safety confirmation command to the detonator, and the detonation controller unlocks and charges and detonates the electronic detonator after receiving the safety confirmation command; And fourthly, after the unmanned aerial vehicle sends a safety confirmation instruction, monitoring the explosion dangerous area and judging whether explosion interruption operation is carried out. Particularly, the safety identification method in the first step is a thermal imaging identification method, and the thermal imaging sensor senses the heat distribution information of the explosion dangerous area so as to detect whether a movable person or animal exists in the explosion dangerous area. Particularly, the safety recognition method in the first step is an image recognition method, and whether a moving person or animal, a static person-shaped outline and an animal outline exist in the blasting dangerous area or not is detected through a high-definition camera and a related algorithm. Particularly, the driving-off program in the second step is a voice driving-off program, and a loudspeaker carried by the unmanned aerial vehicle plays a preset driving-off sound effect to remind or urge people or animals in the explosion dangerous area to be far away from the area.
