The existing delay time design mode of the industrial electronic detonator is generally to set the row number of blast holes, the number of each row of blast holes, the row delay time and the hole delay time, and then obtain a delay time design list of the industrial electronic detonator. The design method has great limitation, and the delay time of each industrial electronic detonator cannot be visually checked; when a certain row of blast holes are discontinuous, the delay time is designed according to the continuous time, and the final blasting result is influenced if a designer does not carefully check the delay time; when the modification is carried out, all delay time after the discontinuous blast hole needs to be modified, the workload is large, and the operation is complicated.

Detailed Description
The present invention will be described in further detail with reference to test examples and specific embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.
Example 1
As shown in fig. 1, the embodiment provides a delay time design method for an initiation network of an industrial electronic detonator, which includes the following steps:
a1, inputting the position information of the blast hole where the electronic detonator is located;
inputting the position information of blast holes in which electronic detonators are positioned in blasting construction, wherein the position information can represent the relative position of each blast hole in a real construction environment;
a2, inputting parameters such as hole pitch, row pitch, hole delay time, row delay time and the like, selecting an initiation point, and calculating and designing the delay time of each industrial electronic detonator by combining the position information of the blast holes obtained in the step A1.
After the initiation point is selected, the initiation time of the initiation point is known; and calculating the delay time of the industrial electronic detonator in a mode that the delay time of all industrial electronic detonators is calculated by combining the initiation time of initiation points and calculating the time increment between other blast holes with delay time to be solved according to the position information of the blast holes, the hole pitch, the row pitch, the hole delay time and the row pitch delay time.
As shown in fig. 4, the electronic detonators of each row have a delay time deltat between holesaDesigning delay time, wherein the interval time of blasting delay time of each row of electronic detonators needs to meet the requirement of inter-row delay time delta tb. In the existing design method, because the chip codes of the electronic detonators are only associated with the serial numbers in the rows of the electronic detonators during registration, and the positions of blast holes are not considered (namely, only the relative position relation of the blast holes in each row is considered, but the position relation of the blast holes among the rows is not considered), when the electronic detonators are irregularly distributed, errors may exist in the designed delay time. For example, the electronic detonator arrangement shown in fig. 4, wherein the black filled circle indicates that the detonator is required to be arranged at the position, and the white filled circle indicates that the detonator is not arranged at the position. If there is a delay between the holesThe time is 25s, the inter-row delay time is 65s, and if the design is adopted, the delay time of the first two rows in fig. 4 is shown in table 1:
TABLE 1 delay time Table of the existing design method
1 2 3 4 5
1 - 0s - 25s -
2 40s 65s 90s 115s 140s
In the existing design method, because the positions of blast holes are not considered, delay time is designed only according to the row internal numbers of the grouped electronic detonators, the phenomenon of hole shortage at the positions (1 and 3) cannot be well processed, the delay time at the positions can be ignored, the delay time is calculated for the blast holes at the positions (1 and 4) in sequence by input, and at the moment, the row interval delay time at the positions (1, 4) and (2 and 4) of the blast holes is 90s and is inconsistent with the preset delay time rule of the row interval delay time of 65s, so that the blasting time of the detonators is not uniformly distributed, and the blasting effect is influenced.
In the method described in this embodiment, because the position of the blast hole is considered, and the position of the missing hole is not ignored when the delay time is designed, the delay time is designed more reasonably, the delay time does not need to be modified manually, the design is simpler and more convenient, if the delay time between the holes is 25s, the delay time between the rows is 65s, and if the design method described in this embodiment is adopted, the delay time of the first two rows in fig. 4 is shown in table 2:
TABLE 2 delay timetable of the design method described in this example
Figure BDA0002557907460000061
Figure BDA0002557907460000071
The delay time design method described in this embodiment is applicable to the conventional end detonation mode and the intermediate detonation mode. When the initiation point is selected, if a middle initiation mode is selected, only any blast hole in the middle can be selected; and by selecting an end detonation mode, only any blast hole at the edge of each row can be selected.
Preferably, the parameters input in step a2 further include the firing time of the first detonating blasthole. The excitation time of the first detonation blasthole refers to the detonation time of the detonation blasthole, and the default is 0.
As shown in fig. 4, the calculation method of the delay time is explained in detail by combining the common rectangular (square) hole arrangement method, taking the upper left corner as the origin, the left-to-right direction as the X-axis direction, and the top-to-bottom direction as the Y-axis direction, and using the rectangular coordinates to represent the position of the blast hole, if a is the hole pitch, b is the row pitch, Δ t isaIs the inter-pore lag time, Δ tbFor the inter-row delay time, the hole of the initiation point is defined as K, and the coordinate thereof is (x)k，yk)，ΔtkRepresenting the initial delay time of the initiation point K; the blast hole to be solved for the delay time is marked as I, and the coordinate of the blast hole is (x)i，yi)ΔtiThe delay time of the point I is represented and is the delay time to be solved;
for any blast hole, the delay time delta tiComprises the sum of two parts, wherein the two parts are respectively the initial delay time delta t of the blast hole of the initiation pointkAnd the relative delay time of the blasthole relative to the blasthole of the initiation point; the delay time of the initiation point is set by a designer according to actual needs; the relative delay time consists of two parts of X-axis direction delay and Y-axis direction delay, and is the sum of the two parts; the delay time in the X-axis direction is determined by the actual distance between two blast holes in the X-axis direction and the set delay time delta t between the two blast holesaThe delay time in the Y-axis direction is obtained by calculation according to the actual distance between two blast holes in the Y-axis direction and the set row-to-row delay time delta tbAnd (6) calculating.
The triangular (quincunx) hole arrangement mode adopts a calculation mode of delay time when the end part and the middle part are detonated, which is similar to the square hole arrangement mode and is not described in detail herein.
And (3) for the working conditions, carrying out zero resetting on the calculation results of the delay time of all the blast holes, namely selecting the minimum numerical value if the delay time smaller than 0 appears in the calculation results of the delay time, and if the minimum numerical value is-a (a is a non-negative integer), increasing a for the delay time of all the blast holes integrally, wherein the obtained result is the final calculation result of the delay time of the blast holes.
Preferably, the position information of the blastholes in the step a1 is associated with chip codes of the electronic detonators and displayed in a graphic form to generate a blasthole position schematic diagram, and each blasthole icon in the blasthole position schematic diagram is associated with a database, and the database stores the chip codes of the electronic detonators, the positions of the blastholes, and the solved delay time of the industrial electronic detonators set for each blasthole. The database may be in the form of a list or the like. The designed delay time is displayed through the icons, so that the method is more visual, and meanwhile, the blast hole icons are associated with the database, so that the modification of the chip code delay time of the electronic detonator is more convenient.
The main purpose of this embodiment is to solve the problem that the delay time of industrial electronic detonators in large-scale open-air deep hole blasting field is inconvenient to design, not enough in practicability, not enough in flexibility, not enough in visual display and complex in operation. In the existing design method, because the chip codes of the electronic detonators are only associated with the serial numbers in the rows of the electronic detonators during registration, and the positions of blast holes are not considered (namely, only the relative position relation of the blast holes in each row is considered, but the position relation of the blast holes among the rows is not considered), when the electronic detonators are irregularly distributed, errors may exist in the designed delay time. According to the method, the position information of the blast holes is input, the relative position relation among the blast holes is comprehensively considered, the inputted hole distance, row distance, hole delay time and row delay time are combined, the initiation point is selected, the delay time of each industrial electronic detonator is accurately calculated, the design result is displayed in a mode of graphic display and list display, the design is simple and convenient, the operation is convenient, various design requirements can be met, the practicability is high, the operation time can be reduced, and the working efficiency is improved. The method can optimize the blasting effect according to the complicated and changeable field actual conditions, is simple and convenient to operate and high in practicability, and can effectively improve the working efficiency.
Example 2
The embodiment provides a method for registering an industrial electronic detonator priming circuit, so as to better realize that the chip code of the electronic detonator mentioned in the step A1 is associated with the position information of the blast hole, and the chip code is displayed in a graphic form to generate a schematic diagram of the position of the blast hole. The industrial electronic detonator priming circuit registration method comprises the following steps:
step S1, generating a blast hole position schematic diagram according to a hole arrangement mode among blast holes, and obtaining position information of each blast hole according to the blast hole position schematic diagram, wherein the position information of each blast hole is expressed in a mathematical form; the hole distribution mode among the blast holes is generally rectangular hole distribution and triangular hole distribution; the position coordinates of the blast hole can be expressed in mathematical forms such as arrays, rectangular coordinates, affine coordinates, vectors and the like;
the actual arrangement of the blast holes is often irregular due to the influence of factors such as environment, and the blast holes are represented by circles as shown in a schematic diagram of the positions of the blast holes in fig. 2; wherein the solid circular part represents the location of arranged blastholes, the four corners of which are affected by the environment, and blastholes are not arranged, thus making the arrangement of the whole blastholes irregular. And generating a regular schematic diagram of the positions of the blast holes according to the hole distribution mode among the blast holes. The regular schematic diagram of the positions of the blastholes, that is, the relative positional relationship among all blastholes in the diagram, conforms to a certain rule, for example, adjacent blastholes may form the same shape, such as a rectangle, a parallelogram or a triangle. In the diagram shown in fig. 2, the blastholes are arranged in a rectangular manner, and four corners are supplemented according to the hole arrangement manner, so that a regular blasthole position schematic diagram (i.e. a 4 × 5 rectangular blasthole position schematic diagram) is generated; and then obtaining and showing the positions of the blast holes in the blast hole position schematic diagram according to the rows of the blast holes and the number of the blast holes in each row. If the upper left corner is used as the origin, the direction is from left to right, the direction is from top to bottom, the position of each blast hole is represented in a rectangular coordinate mode, and in the schematic diagram of the position of each blast hole:
(1，1)，(1，2)，(1，3)，(1，4)，(1，5)；
(2，1)，(2，2)，(2，3)，(2，4)，(2，5)；
(3，1)，(3，2)，(3，3)，(3，4)，(3，5)；
(4，1)，(4，2)，(4，3)，(4，4)，(4，5)。
step S2, registering each industrial electronic detonator, and associating the chip code of each industrial electronic detonator with the position of the corresponding blast hole;
the schematic diagram of the positions of the blast holes generated in step S1 is a diagram generated by supplementing the arrangement manner of the blast holes, as shown in fig. 3, where the white solid circles indicate that no blast holes are arranged during actual construction. Correlating the chip code of the electronic detonator with the position information of the blast hole corresponding to the chip code; in conjunction with the blast hole arrangement diagram shown in fig. 2, this association is represented in the form of an array:
(1，1，N)，(1，2，000)，(1，3，001)，(1，4，002)，(1，5，N)；
(2，1，003)，(2，2，004)，(2，3，005)，(2，4，006)，(2，5，007)；
(3，1，008)，(3，2，009)，(3，3，010)，(3，4，011)，(3，5，012)；
(4，1，N)，(4，2，013)，(4，3，014)，(4，4，N)，(4，5，N)。
truly mapping the relative position relation between blast holes in blasting construction into a schematic diagram, selecting the mapped blast holes to be associated with the electronic detonator chip codes, and establishing the corresponding relation between blast hole position information and the electronic detonator chip codes; by establishing the relation, the subsequent delay time design is more convenient, and meanwhile, the construction condition is visually displayed, so that the later construction is convenient.
Preferably, when the electronic detonators are registered in step S2, the serial numbers in the rows of the electronic detonators, the chip codes of the electronic detonators and the positions of the corresponding blast holes can be associated with each other.
Preferably, as shown in fig. 3, the schematic diagram of the location of the blast holes is shown in the form of a graph, and each blast hole icon in the graph is associated with a database, and the database stores the chip codes of the electronic detonators and/or the serial numbers of the electronic detonators in the rows, and the location information of the blast holes. The database may be in the form of a list or the like.
Distribution conditions of the electronic detonators can be visually displayed through the graphs, and meanwhile, the blast hole icons are associated with the database, so that addition or modification of chip codes of the electronic detonators and/or serial numbers in rows of the electronic detonators, positions of the blast holes and the like is more convenient.
The existing registration method only inputs the serial number in the rows of the electronic detonators and the chip code of the electronic detonators, and does not correlate the position relationship of the blast holes, namely only the relative position relationship of the blast holes in each row is considered, but the position relationship of the blast holes among the rows is not considered. Therefore, the actual construction position of the electronic detonator cannot be well represented for the phenomenon of hole shortage. Meanwhile, the delay time of the electronic detonator needs to be designed by considering the delay time relationship between the left blast hole and the right blast hole in the row and the delay time relationship between the upper blast hole and the lower blast hole in the row, and because the relative position relationship of the blast holes is not related in the conventional registration mode, the delay time of the hole shortage phenomenon needs to be designed by later-stage manual calculation and modification, and the design process is complicated. Therefore, in the existing registration method, during actual construction, the construction condition may not accord with the design condition; and also affects the design of subsequent deferral times. In the embodiment, the position of each blast hole is obtained by generating a regular blast hole position schematic diagram, and the positions of the blast holes are represented in the forms of arrays, rectangular coordinates, affine coordinates, vectors and the like, so that the influence of gaps where electronic detonators are not arranged on subsequent construction is considered, and the registration effect is better; meanwhile, the chip code of the electronic detonator is associated with the position of the corresponding blast hole, so that the subsequent delay time design is facilitated, the construction condition is visually displayed, the construction is facilitated, and the construction efficiency is improved.

When the electronic detonator is registered, the schematic diagram of the position of the blast hole is displayed in a graph form, each blast hole icon in the graph is associated with the database, the position of the blast hole, the chip code of the electronic detonator, the chip code in the row of the electronic detonator and the delay time are stored in the database, and the purpose of modifying the delay time can be achieved by modifying the parameter of the blast hole icon or modifying the data in the database. And modifying the delay time in any one of the database or the graph, and automatically corresponding the other delay time. The method enables the modification of the delay time to be more intuitive, diversified and convenient.
