Description

Technical Field

[0001] The present invention relates to the technical field of industrial automation scheduling, and specifically provides a method and system for generating a startup strategy for a batch blasting program. Background Art

[0002] In recent years, with the rapid development of industrial automation, digitalization, and information processing technologies, blasting control systems are gradually transforming from traditional manual operations and fixed-program controls to intelligent and networked automatic blasting systems. In high-risk industrial fields such as mining and building demolition, traditional blasting technologies initially relied on manual setting of detonation timings and fixed delays, suffering from low operation efficiency, lagging information feedback, and significant safety hazards. Subsequently, with the application of programmable logic controllers (PLCs) and dedicated detonation controllers, blasting systems have gradually achieved partial automatic monitoring and scheduling of equipment status, environmental parameters, and detonation timings. With the help of sensor networks and real-time data processing technologies, it is possible to perform status detection and remote monitoring of on-site equipment. However, existing technologies still have deficiencies in aspects such as overall system integration, data preprocessing, dynamic scheduling optimization, and safety interlock control. For example, self-check feedback is not comprehensive, the allocation of detonation sequences and time windows is not precise enough, and the redundant verification mechanism for detonation signals is imperfect. As a result, when facing equipment failures and environmental changes, blasting operations cannot achieve sufficient real-time response and risk prevention and control.

[0003] Current blasting control systems mostly adopt fixed parameters and preset program modes. Although they achieve automatic detonation to a certain extent, they still fail to meet the strict requirements for safety and intelligent scheduling in high-risk industrial sites in key aspects such as equipment status detection, priority division of blasting areas, time window allocation, and safety verification. When some systems perform equipment self-checks, it is difficult to promptly detect problems such as poor detonator connections, abnormal power supply levels, or circuit conduction, which in turn affect the accuracy and reliability of the overall blasting strategy. At the same time, fixed timing arrangements are difficult to take into account the mutual influences between regions, easily resulting in uneven blasting effects and an increased risk of vibration superposition. Summary of the Invention

Description of the Drawings

[0045] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the drawings in the following description are only some embodiments of the present invention, and those of ordinary skill in the art can obtain other drawings based on these drawings without creative efforts.

[0046] Figure 1 It is the overall flowchart of a method for generating a startup strategy for a batch blasting program provided by the first embodiment of the present invention. Detailed Embodiments

[0047] In order to make the above-mentioned objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0048] Embodiment 1, referring to Figure 1 , which is an embodiment of the present invention, provides a method for generating a startup strategy for a batch blasting program, including:

[0049] S1: Collect blasting task data, perform preprocessing, and establish a digital model of the blasting area map.

[0050] Further, the blasting task data includes receiving blasting task information input by the user, specifically including blasting area division, the number and location of blasting points in the area, priority setting, and safety constraints.

[0051] Process the blasting task information to establish a digital model of the map; the area set is .

[0052] Through this kind of modeling, the originally chaotic blasting task information becomes structured data, which can automatically analyze the relationships between blasting points and safety constraints, greatly improving the accuracy and safety of subsequent scheduling calculations.

[0053] The blasting point information includes: \(n\) represents the number of blasting areas, which is a natural number; represents the th blasting area. If each area contains multiple blasting points, the blasting point formula is expressed as:

[0054] , ;

[0055] Among them, represents the th blasting point (blasting task node) within the area. The spatial coordinate formula of the blasting point is expressed as:

[0056] ;

[0057] Among them, represents the degree of structural influence of the blasting point on the area; represents the time window allowing initiation. Through on-site geological surveys and experimental data, the potential impact of each blasting point on the regional structure under different geological conditions can be quantified and converted into a numerical parameter .

[0058] The set of safety constraints includes the minimum safety distance , the minimum initiation interval between adjacent blasting points , and the maximum initiation delay in the same area .

[0059] Divide the blasting area , including several blasting points ; create task nodes for each blasting point, and assign identification numbers, position coordinates, expected initiation time windows, and blasting point importance priorities. Taking the blasting points as nodes, construct a task graph, and the formula is expressed as:

[0060] ;

[0061] Among them, represents all nodes in the task graph, that is, the set of all blasting points ; represents the set of edges in the task graph; each edge indicates that there are safety or timing constraints between two blasting points. If the distance between two blasting points is lower than the safety threshold, the formula is expressed as:

[0062] ;

[0063] Among them, represents the spatial coordinates of the explosion point , that is, the position of the explosion point in three-dimensional space. represents the explosion point and the Euclidean distance between them. Then create a constraint edge between the two explosion points:

[0064] ;

[0065] Among them, represents the earliest allowable detonation time, represents the latest allowable detonation time.

[0066] Obtain the on-site real-time environmental parameters and incorporate them into the blasting strategy constraint conditions; the constraint conditions include the minimum safety distance, the minimum detonation interval between adjacent explosion points, and the maximum detonation delay in the same area.

[0067] It should be noted that through the above preprocessing and parameter modeling, the original blasting task data is converted into a digital graph model, enabling the system to automatically analyze the dependency relationships and safety constraints between explosion points using computer data processing means, providing a complete and structured data basis for subsequent optimization algorithms, thereby improving the accuracy and safety of task scheduling.

[0068] S2: Check the status of the blasting unit equipment and map it to the graph digital model.

[0069] Furthermore, the received self-check command includes that the central control unit issues a self-check command to the edge control terminal, and the edge control terminal controls the blasting unit to independently perform equipment status checks.

[0070] The equipment status check includes circuit continuity detection, battery power and power status detection, and connection integrity detection with the detonator.

[0071] The edge control terminal converts the status of the blasting unit equipment into a three-dimensional binary state vector through an electronic signal , and associates the state vector with the explosion point corresponding to the graph model , and feeds back the self-check result to the central control unit.

[0072] Furthermore, each edge control terminal controls the connected blasting unit to independently perform the following status detections: circuit continuity detection: detect whether the blasting circuit is unobstructed; battery power and power status detection: ensure sufficient and stable power; detonator connection integrity detection: verify that the actual connection status is consistent with the planned information.

[0073] The detection results will be converted into a three-dimensional binary state vector. [1, 1, 1] indicates that everything is normal. If any item is 0, it means an anomaly, and then it will be fed back to the central control system.

[0074] The central system will aggregate all detection results and construct a global state matrix. If any device is found to be faulty, the system will automatically remove the corresponding blasting point from the task graph and regenerate the detonation strategy. Meanwhile, the edge terminal will also mark that the device needs to be repaired, reminding relevant personnel to intervene.

[0075] It should be noted that this self-check mechanism utilizes the independent detection and digital state feedback of the edge terminal, effectively ensuring that all devices participating in the blasting are in normal working condition. By establishing the state vector and the global state matrix, the central control unit can real-time monitor the health status of the devices, ensuring that all devices meet the safety requirements before executing the blasting instruction, greatly reducing the risk of safety accidents caused by device failures.

[0076] S3: Divide the priority of the blasting area and allocate time windows, construct a priority ranking according to the dynamic time window constraint, use the constrained greedy scheduling algorithm to optimize the priority ranking, and perform blasting task scheduling.

[0077] Furthermore, the step of dividing the priority of the blasting area and allocating time windows includes that, according to the received task information, the central control unit uses a weighted algorithm to determine the priority of each blasting area.

[0078] Let the influence degree of the blasting point position on the area be , then there is:

[0079] ;

[0080] Among them, represents the weight coefficient, and its value range is 0.5 - 2.0, set to 1.0; represents the weight coefficient, and its value range is 0.1 - 1.0, set to 0.5. represents the area the number of blasting points inside.

[0081] Allocate detonation time windows for each area to ensure that the detonation times of different areas do not interfere with each other; assume that each blasting point has a detonation time window , for the th blasting point there is .

[0082] ;

[0083] The calculation formula for the start of the area window is expressed as:

[0084] ;

[0085] Among them, represents the earliest moment when the area is ready. represents the minimum safety initiation interval between areas. represents the end moment of the previous high-priority area.

[0086] The initiation time window is affected by the dynamic time window constraint, specifically including:

[0087] Safety interval constraint, the initiation of adjacent blasting points needs to meet the minimum interval:

[0088] ;

[0089] Overall time limit of the area, all blasting points within the blasting area shall meet:

[0090] ;

[0091] External condition constraint, including wind speed, geological condition, construction progress, forms a dynamic time window constraint function:

[0092] ;

[0093] Among them, represents a function that depends on environmental factors and blasting point attributes The external condition constraint and the safety constraint condition together constitute the dynamic time window constraint.

[0094] Perform priority sorting. Assume that each blasting point has a static priority value , combined with other dynamic factors to generate a scheduling priority function, which is expressed by the formula:

[0095] ;

[0096] Among them, represents the degree of influence of the blasting point position on the regional structure; represents the average safety distance between the blasting point and its nearest neighbor. The degree of influence of the blasting point position on the regional structure is restricted by the geological condition, and the average safety distance between the blasting point and its nearest neighbor is restricted by the wind speed and construction progress.

[0097] Previous scheduling methods may only look at the task order or only focus on the safety interval. The algorithm incorporates priority, blasting importance, safety boundary, and site environment into a comprehensive sorting system, which is more comprehensive and intelligent. Score each possible time point and select the one with the lowest score as the optimal time point, rather than just making a hard judgment. This method is more flexible and can also handle complex situations.

[0098] Optimize all detonation times using a constrained minimization algorithm according to the number of detonation points, spatial layout, and safety constraints to obtain the detonation sequence and precise detonation moment for each detonation point;

[0099] Initialize the scheduling detonation time grid and set the global scheduling time grid as where represents the minimum detonation interval step size, represents the maximum allowable detonation time;

[0100] For each sorted node , obtain its time window , and generate a set of candidate time points:

[0101] ;

[0102] Traverse to find the earliest time point that satisfies the dynamic time window constraint;

[0103] For each candidate detonation time of the detonation point, the system will sequentially perform safety constraint judgments. This judgment is based on all the scheduled adjacent detonation points in the detonation point graph that have conflict edges with the current detonation point.

[0104] The system checks the time intervals between the candidate time points and the adjacent detonation points with all the already assigned detonation times. If any interval is less than the minimum safety time interval set by the system, the candidate time point will be excluded and not assigned.

[0105] Among the candidate time points, the system searches for the first time point that satisfies the safety constraints in ascending order from early to late and assigns it as the final detonation time of the detonation point.

[0106] If a qualified time point is found, the system immediately completes the time assignment for the detonation point and records the scheduling result for subsequent judgments of other detonation points.

[0107] If no qualified legal detonation time can be found among all the candidate time points, the system will mark the detonation point as not automatically schedulable and record the conflict information.

[0108] In this case, a backup processing mechanism can be triggered, including manual intervention, dynamically adjusting the time window range, or re-optimizing the previous scheduling order, to attempt to schedule the unassigned detonation points again.

[0109] After each new assignment of the detonation point time, the system checks all the already assigned detonation times within the current blasting area to ensure that the maximum detonation time difference within the area does not exceed the maximum area delay threshold set by the system.

[0110] If the overall delay of the area exceeds the limit, the system will send a readjustment signal, roll back part of the blast point allocation, and give priority to making adjustments within the area to ensure the timing coordination of the area.

[0111] For all nodes connected to it , if has been allocated, then:

[0112] ;

[0113] If all the safety interval requirements of the conflict edges are met, allocate the current time point and let .

[0114] If no appropriate time point can be found, set it to be pending and dynamically expand the time window. Output the final detonation time of each blast point , and verify whether all schedules meet the constraint conditions of execution within the time window, safety interval between adjacent blast points, and maximum delay limit of the area.

[0115] The verification of the safety of the blasting strategy includes that the central control unit generates a preliminary blasting strategy according to the blasting task scheduling result, conducts interlock status verification, sets redundant verification of the detonation signal, and communicates through the primary and backup dual channels.

[0116] The interlock status verification includes: real-time checking whether there are unevacuated personnel in the blasting area. If the evacuation is not completed, the interlock will not be released; confirming that the equipment in the blasting impact area has stopped operating and has been evacuated to a safe area. If not satisfied, the interlock will not be released; the switches of the on-site key safety facilities must be placed in the preset safe state. If not satisfied, the interlock will not be released.

[0117] The setting of redundant verification of the detonation signal includes that after receiving the detonation instructions from both the primary and backup channels, the edge control terminal will strictly compare the two instruction messages; verify whether the instruction sequence numbers are the same, verify whether the delay time parameters are the same, and verify whether the digital signature or verification code is correct.

[0118] If all the verification items match exactly, the terminal determines that the instruction is valid and enters the pending execution state; otherwise, the terminal immediately refuses to execute and feeds back the abnormal information to the central control unit, and the central system will review again or resend the instruction.

[0119] The central control unit reconfirms the status preparation of each blasting unit, generates the final strategy table, including the detonation delay parameters and detonation order of each unit, and encapsulates the strategy parameters with digital signatures and verification codes.

[0120] It should be noted that through mathematical modeling and optimization algorithms, the intelligent scheduling of the priority of the blasting area and the initiation timing of the blasting points is realized, and at the same time, a multiple safety verification mechanism is embedded. This not only ensures the efficient scheduling of blasting operations, but also ensures the absolute safety of the initiation process through measures such as interlocking and redundant verification.

[0121] S4: Use the result of the blasting task scheduling as the blasting strategy, conduct safety verification of the blasting strategy, send the blasting strategy to the edge control terminal and start the chain safety interlock control, and perform real-time initiation execution and status monitoring feedback.

[0122] The sending the blasting strategy to the edge control terminal includes that the central control unit sends an initiation instruction to each edge control terminal through the network.

[0123] After receiving the instruction, the edge terminal performs multi-channel redundant signal verification, confirms by comparing the consistency, and if the confirmation is successful, the instruction is valid.

[0124] After confirming that the instruction is valid, the edge terminal stores the initiation parameters in the local memory, updates the terminal status to the instruction has been received and waiting for initiation, and returns an instruction confirmation signal to the central control unit, informing the central that the instruction has been successfully received and passed the verification.

[0125] After receiving the information that the instruction is valid, the central control unit conducts a secondary confirmation of the on-site safety status, including the status of the safety key switch and the status of the interlock device.

[0126] If the two safety condition confirmations are successful, after the central control operator conducts dual authorization and double verification, an initiation permission signal is issued, the chain interlock is released, and the edge control terminal enters the standby initiation state.

[0127] The performing real-time initiation execution and status monitoring feedback includes that according to the blasting strategy, the edge control terminal drives the initiation device to start the detonator in a predetermined order and at a predetermined time.

[0128] Furthermore, for the first-level unlocking, the central control system confirms that all blasting units have passed the self-check.

[0129] After the on-site safety interlock conditions (such as personnel evacuation, equipment stop, key switch status) are met, the system enters the armed state.

[0130] The operator conducts the first authorization, usually electronic key or password verification.

[0131] The central control system sends an "allow arming" signal to the on-site safety relay circuit, and at this time the relay is not closed.

[0132] After each terminal executes the initiation action, it real-time monitors the initiation success status, the change of the circuit status, and the data of the vibration sensor, and feeds back the initiation execution result to the central control unit.

[0133] The central control unit displays the execution progress and status information in real time. If any abnormality is detected during the monitoring process, the safety emergency handling logic is immediately executed to urgently stop the subsequent blasting or reschedule the remaining blasting sequence.

[0134] For the second-level unlocking, the overall blasting person in charge or the safety engineer conducts a second authorization (on-site or remotely) to confirm that the blasting can be carried out safely.

[0135] The central control re-verifies the on-site safety interlock conditions for double confirmation.

[0136] After the conditions are met, the safety relay circuit is closed and the initiation circuit is powered up for preparation.

[0137] After the double unlocking is completed and all on-site status feedback is obtained, the central control system allows the final initiation instruction to be issued.

[0138] It should be noted that through the issued strategy, two-stage interlock, and multi-channel redundancy verification, it is ensured that the initiation instruction is absolutely reliable during the transmission and execution processes. The real-time status monitoring and closed-loop feedback mechanism enable the central control system to accurately grasp the on-site blasting process, and can respond quickly once any abnormality occurs, greatly improving the safety and controllability of the entire blasting process.

[0139] Embodiment 2 is an embodiment of the present invention, which provides a method for generating a start strategy for a batch blasting program. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0140] First, it is detected in real time whether there are unevacuated personnel in the blasting area, whether all equipment has stopped operating, and whether the key safety facilities are in the preset safe state; at the same time, through the main and standby dual-channel communication, the issued initiation instruction is strictly compared (verifying the sequence number, delay time, and digital signature). After confirmation, each edge terminal enters the pending execution state. Finally, the central control unit issues the final strategy to each edge control terminal through the network. The edge terminal stores the received instruction locally and performs the actual initiation action on-site, and at the same time, monitors the initiation status in real time through sensors and feeds it back to the central system. The entire process realizes the safety interlock control and real-time monitoring closed-loop feedback. The data acquisition, optimization scheduling, and safety interlock of the entire experimental process are all run on a dedicated industrial control computer, ensuring the real-time performance and reliability of the operation data.

[0141] The test subjects all had the same number of area divisions (3 areas) in the blasting task scheduling, but the number of blasting points within each area varied slightly, ranging from 12 to 20, indicating a certain degree of complexity in the actual task. The method for generating the detonation strategy adopted in this embodiment can accurately consider the priority and spatial distribution of the blasting points within each area. Therefore, the accuracy of the blasting point positions all remained above 96.8%, with an average of about 98%, demonstrating the high-precision advantage of the present invention in coordinate positioning and data modeling. The self-check passing rate index reflects the reliability of each edge control terminal in the device status detection link. The highest self-check passing rate among the test subjects reached 100%, and the lowest was 95%, indicating that even if there were a small number of device abnormalities, through automatic state matrix processing, the abnormal devices could be promptly eliminated to ensure the safety of subsequent strategy scheduling.

[0142] In addition, the detonation time error index shows that in this embodiment, the detonation time of the blasting points is optimized through a constrained minimization algorithm, so that the deviation between the actual detonation time and the ideal time is controlled between 30 and 75 milliseconds. Compared with the error of more than 200 milliseconds commonly existing in the prior art, the present invention significantly improves the timing accuracy. In terms of system response delay, the response delays of all test subjects were within the range of 110 - 150 milliseconds, proving that through the primary and backup dual-channel communication and real-time status feedback mechanism, the time interval for instruction transmission and execution was effectively shortened, thus ensuring the efficient scheduling of the entire batch blasting process.

[0143] Data comparison shows that this embodiment has obvious advantages in device self-check, blasting point positioning, detonation timing optimization, and safety interlock. Compared with traditional methods, traditional systems often have safety hazards due to unclear device status or large errors in detonation sequence. However, in this embodiment, through the construction of a graph model and an optimization algorithm, abnormal devices are accurately identified and eliminated, and strict time window allocation and redundancy check measures are used to achieve full-process safety interlock. Especially in a complex environment, the accuracy of blasting point positions is high, the self-check passing rate is stable, and the detonation time error is low.
