Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart illustrating an implementation of an advanced forecasting method for a digital detonator according to an embodiment of the present invention.
Referring to fig. 1, in one aspect, an embodiment of the present invention provides a method for advanced prediction of a digital detonator, where the method is applied to a control center, the control center is connected to a first line and a plurality of second lines, the first line is connected in parallel with each of the second lines, the first line is connected to a digital detonator initiator, and each of the second lines is connected to a digital detonator, and the method includes: operation 101, acquiring a detonation instruction, wherein the detonation instruction is used for indicating that the digital detonators detonate in sequence according to a preset time interval; in operation 102, controlling a digital detonator initiator to detonate the digital detonators, so that the digital detonators are detonated in sequence according to a preset time interval; and operation 103, recording vibration data corresponding to the digital detonator when the detonation of the digital detonator is detected.
The digital detonator initiation method provided by the method can be applied to geological survey, and particularly, the method is particularly suitable for advanced tunnel prediction operation. The method can be used for continuously detonating a plurality of digital detonators, the method is characterized in that the control center is connected with the first circuit, the digital detonator of the second circuit is detonated through the digital detonator initiator of the first circuit, the control center is also connected with the plurality of second circuits in parallel, and the digital detonators on each second circuit can be independently detonated, so that the purpose that the digital detonator initiator sequentially detonates the digital detonators based on preset time intervals is achieved. Compared with the traditional detonator and the old detonator, the digital detonator is detonated by the digital detonator initiator, so that the time delay caused by the digital detonator in the detonation process can be reduced, and the actual detonation time of each digital detonator can be well matched with the recorded detonation time corresponding to the vibration data. Under the condition that the detonation of the digital detonator is detected, the control center can also synchronously acquire and record corresponding automatic records with the detonation, so that the data acquisition work corresponding to the detonation is more accurate and convenient.
Specifically, the control center of the method is used for realizing the integral control of the whole digital detonator detonation method. The control center is provided with a plurality of trigger interfaces, each trigger interface is used for connecting a circuit, for example, a first circuit is connected to a first trigger interface, each second circuit is connected to each other trigger interface, and the circuit connected to each trigger interface belongs to a parallel connection mode. The first circuit is connected with a digital detonator initiator, and the digital detonator initiator is used for initiating digital detonators. Each second line is connected with a digital detonator, and it can be understood that the digital detonators on each second line are respectively arranged on initiation points needing to be initiated, for example, when a tunnel is subjected to tunnel advance forecast, a plurality of initiation points are determined on the tunnel according to measurement and calculation, then a digital detonator is arranged at each initiation point to initiate to generate vibration, so that the control center can collect and record vibration data corresponding to the vibration generated by initiation of the digital detonators. It is to be added that when the control center performs operations 101 to 103, both the first line and the second line are closed lines.
After the line connection is completed, in the method operation 101, the initiation instruction may be from an exploder, and when the exploder determines the site safety, the initiation instruction is sent out, and the exploder may send the instruction to the control center through the user terminal. The initiation instruction is used for indicating the digital detonators to be sequentially initiated according to a preset time interval, the preset time interval can be preset on an acquisition interface of a control center by an exploder, an instructor, an operator or other operating personnel, the preset time interval is based on the maximum time interval which is not more than the maximum time interval which can be set by the digital detonator initiator, the preset time interval can be 500 plus 1200ms in general, and optionally, the preset time interval is set to 1200ms when the maximum time interval which can be set by the digital detonator initiator is 1200 ms.
In the method operation 102, after the control center receives the initiation instruction, the control center controls the digital detonator initiator to initiate the digital detonator, so that the digital detonator is sequentially initiated according to the preset time interval, and therefore, after the initiation instruction is sent once, the subsequent digital detonator can be continuously initiated, the digital detonator is sequentially initiated according to the preset time interval, and the time for advanced prediction observation is greatly saved. In another case, each digital detonator can be set with detonation time corresponding to the preset interval time, the control center controls the digital detonator exploder to send instructions to the digital detonators at the same time, and the digital detonators explode after receiving the instructions under the condition of the time detonation time, so that the digital detonators explode in sequence according to the preset time interval.
In operation 103 of the method, when the control center detects that the digital detonator is detonated, the control center may detect and record vibration data corresponding to the digital detonator through the detector. The detector is in communication connection with the control center and is arranged at a preset data acquisition place. Because the first circuit and the second circuit are connected in parallel, the control center can trigger the detector to carry out data acquisition work only by detecting any signal corresponding to the detonation of the digital detonator, and record corresponding vibration data. Specifically, in one case, the control center may determine whether the digital detonator initiator sends the trigger instruction by detecting the first line to determine whether the digital detonator is detonated, and when the control center detects that the digital detonator initiator sends the trigger instruction, the control center may determine that the control center detects that the digital detonator is detonated, where the trigger instruction is used to characterize that the digital detonator initiator detonates the digital detonator. In another case, the control center may also determine whether the digital detonator detonates by detecting a voltage change of the second line, and it is understood that when the digital detonator detonates, the second line may generate a voltage change, and when the control center detects that the second line may generate a voltage change, the control center determines that the digital detonator detonates. It should be added that the control center may also preset conditions for determining the initiation of the digital detonator, where the preset conditions may be one or more. For example, any of the following may be used: in the first case, in the case when a change in the second line voltage is detected, it is determined that the digital detonator is detonated; under the second condition, when a trigger instruction sent by the digital detonator exploder is detected, the digital detonator exploder is determined to explode; and under the third condition, when the voltage change of the second line is detected and the trigger instruction sent by the digital detonator exploder is detected, the digital detonator exploder is determined to explode. And under the fourth condition, when the voltage change of the second line is detected or a trigger instruction sent by the digital detonator exploder is detected, the digital detonator exploder is determined to explode.
In one embodiment, before obtaining the detonation instruction at operation 101, the method further includes: receiving a detonation setting instruction, wherein the detonation setting instruction comprises a preset time interval and a preset detonation frequency; the preset detonation frequency corresponds to the number of the second lines; the preset detonation times are used for determining the detonation times of the digital detonator for detonating the digital detonator.
It can be understood that the method is used for continuously detonating a plurality of digital detonators, and in the scenario, the detonation time interval between adjacent digital detonators and the number of the digital detonators needing to be detonated need to be determined. Based on this, the method determines a preset time interval and a preset initiation number through an initiation setting command before operation 101.
The detonation setting instruction is set and generated on a display interface corresponding to the control center by an exploder, an instructor, an operator or other operators, or can be sent to the control center by the exploder, the instructor, the operator or other operators through the user side, so that the control center receives the detonation setting instruction. The preset time interval is used for determining the detonation time interval between adjacent digital detonators. For convenience of understanding, a specific implementation case is provided below, the digital detonator initiator does not need to involve a preset time interval when initiating a first digital detonator, the preset time interval is set to 0s, when the digital detonator initiator initiates a second digital detonator, the preset time interval is added on the basis of the time for initiating the first digital detonator to obtain the initiation time of the second digital detonator, and when the initiation time meets the requirement, a trigger instruction is sent to the second digital detonator to initiate the second digital detonator. The preset initiation times are used for determining the number of the digital detonators needing initiation, namely the initiation times are increased by 1 every time the digital detonator initiator initiates, and the digital detonator initiator stops initiating the rest digital detonators under the condition that the initiation times meet the preset initiation times. It is necessary to supplement that the digital detonator initiator also stops the initiation when the digital detonators are all initiated and the initiation times do not meet the preset initiation times. It can be understood that after the control center obtains the detonation instruction, the control center generates an instruction based on the detonation instruction, the preset time interval and the preset detonation times, and sends the instruction to the digital detonator initiator, so as to achieve the purpose of instructing the digital detonator initiator to sequentially detonate the digital detonator according to the preset time interval and the preset detonation times.
In another case, the preset time interval is realized by delayed detonation of the digital detonators, that is, the digital detonators are provided with a timed detonation function, and corresponding detonation time is set for each digital detonator according to the preset time interval, for example, when the preset time interval is 1s, the digital detonator on the first and second lines is set to receive an instruction and then detonate immediately, the digital detonator on the second line is set to receive the instruction and then detonate for 1s, the digital detonator on the third second line is set to receive the instruction and then detonate for 2s, and so on, and details are not described below.
Fig. 2 is a schematic flow chart of the implementation of the detonation permission of the advanced prediction method for the digital detonator according to the embodiment of the invention.
Referring to fig. 2, in an embodiment, before obtaining the detonation instruction at operation 101, the method further comprises: operation 201, acquiring identification information corresponding to all digital detonators through an information acquisition device, and sending the identification information to a monitoring end; operation 202, receiving a feedback notification from the supervisory end, the feedback notification including permission information to operate the digital detonator; and operation 203, setting the digital detonator as an instantaneous digital detonator according to the permission information, so as to detonate the instantaneous digital detonator according to the detonation instruction.
The digital detonator is a controlled article and can be detonated only when the supervision end permits, and therefore the method requires permission of the supervision end to be obtained before operation 101. Specifically, in operation 201, the identification information corresponding to the digital detonators may specifically be a barcode or a two-dimensional code, in actual operation, a plurality of digital detonators may correspond to one identification information, the identification information corresponding to each digital detonator may also be different, the information acquisition device may specifically be an image acquisition device, the control center acquires the identification information corresponding to all the digital detonators through an image, and sends an approval request carrying the identification information to the supervision end to request the supervision end to approve the operation approval of the digital detonators corresponding to the identification information. It can be understood that the identification information carried in the permission request may be one or more, after obtaining the permission request, the supervision terminal sends a feedback notification containing permission information to the operation center, where the permission information contained in the feedback notification at least contains a permission identification for representing that the digital detonator is allowed to be operated; the feedback notification may also contain a permitted time for allowing operation of the digital detonator; when the identification information carried in the permission request is multiple, the permission request can also contain corresponding identification information of the digital detonator allowed to operate and the like.
In operation 203, under the condition that permission information is not obtained, the digital detonator is in a locked state, detonation operation cannot be performed on the digital detonator at this time, the control center can permit the information by analyzing feedback information, the permission information can also include unlocking information for unlocking the digital detonator, the digital detonator is unlocked through the unlocking information, so that the digital detonator is in an unlocked state, the digital detonator can be set and detonated at this time, according to the function of the digital detonator, the digital detonator can also set detonation time, and the digital detonator is set as an instantaneous digital detonator, so that the digital detonator can detonate immediately under the condition that a trigger instruction of the digital detonator initiator is obtained, time delay is avoided, and synchronization between a data acquisition process and a detonation process is further ensured. After the digital detonators are set, an exploder or other operators can send detonation instructions to the control center, so that the control center detonates the instantaneous digital detonators according to the detonation instructions.
In another operation mode, the digital detonator may be subjected to initiation time setting according to the permission information and a preset time interval, so that the digital detonator sequentially initiates according to the preset time interval after receiving the instruction of the digital detonator initiator to replace the operation 203, that is, in one case, the preset time interval for initiating the digital detonator is controlled by the digital detonator initiator, and in the case that the preset time interval meets the requirement, the digital detonator initiator sends the instruction to the corresponding digital detonator, so that the digital detonator is initiated. In another case, the preset time interval of the digital detonator initiation is controlled by the digital detonator, the digital detonator initiator sends instructions to all the digital detonators, and the digital detonators are initiated under the condition that the preset initiation time is reached after the digital detonators receive the instructions.
Fig. 3 is a schematic flow chart of an implementation of the detonation test of the advanced prediction method for the digital detonator according to the embodiment of the invention.
Referring to fig. 3, in an implementation, the control center is further connected with a test line, the test line is connected in parallel with the first line, and the test line is connected with a test detonator; accordingly, before obtaining the detonation instruction at operation 101, the method further includes: operation 301, receiving a test detonation instruction, wherein the test detonation instruction is used for indicating a test detonator to detonate; operation 302, controlling a digital detonator initiator to detonate the test detonator; operation 303, recording test data corresponding to the test detonator when the test detonator is detected to detonate; and operation 304, controlling the digital detonator exploder to explode the digital detonators according to the explosion instruction under the condition that the test data are determined to be abnormal, so that the digital detonators explode in sequence according to the preset time interval.
Before the initiation instruction is carried out, the method also needs to test whether the connecting lines among the control center, the detector, the digital detonator initiator and the digital detonator meet the test requirements. To avoid undesirable vibration data being collected due to an unsatisfactory installation. The method carries out test initiation by arranging a test circuit and a test detonator. The test circuit is also a closed-loop circuit, is connected to a trigger interface of the control center and is connected in parallel with the first circuit and the second circuit, the test detonator is also a digital detonator, and further the test detonator and the digital detonator are detonators with the same model number.
In the method operation 301, an operator sends a test detonation instruction to the control center, the control center receives the test detonation instruction, and the control center detonates the test detonator through the digital detonator initiator according to the test detonation instruction.
In operation 302, the control center may detect whether the test detonator detonates by monitoring the voltage change of the first line and/or the second line, and when it is detected that the test detonator detonates, the control center may transmit a collecting and recording instruction to the geophone to instruct the geophone to collect and record test data corresponding to the test detonator.
In operation 304, the vibration data may be compared to predicted data by a human or a control center to determine whether the test data is abnormal, and the predicted data may be predicted by known parameters of the vibration wave, such as the propagation velocity of the vibration wave. When the test data are determined to be abnormal, the connecting circuit among the control center, the detector, the digital detonator initiator and the digital detonator can be considered to meet the test requirements, and a detonation instruction can be sent to the control center, so that the control center controls the digital detonator initiator to detonate the digital detonator according to the detonation instruction, and the digital detonator is sequentially detonated according to the preset time interval.
In an implementation mode, the first line is also connected with an induction trigger box in series, and the induction trigger box is used for detecting whether the voltage of the second line is abnormal or not; correspondingly, in operation 103, when the detonation of the digital detonator is detected, recording vibration data corresponding to the digital detonator, including: when the digital detonator is detonated, the induction trigger box detects that the voltage of the second line corresponding to the digital detonator is abnormal, and generates a recording instruction to instruct the control center to record vibration data corresponding to the digital detonator through the detector.
Specifically, the method includes the steps that an induction trigger box is further connected in series with a first line, an induction hole for the second line to penetrate through is formed in the induction trigger box, the induction trigger box can sense whether the second line penetrating through the induction hole changes in voltage or not through the induction hole, and when the second line penetrating through the induction hole changes in voltage or not, the induction trigger box sends a recording instruction to a control center so that the control center can determine that the digital detonator explodes, and the control center collects and records vibration data corresponding to the digital detonator through a detector. After all the digital detonators are detonated, the control center can acquire vibration data corresponding to all the digital detonators so as to perform subsequent data analysis. It should be noted that the detector may preset the acquisition time corresponding to each recording instruction, for example, the acquisition time is set to 0.4s, that is, when the detector receives an instruction to acquire and record the vibration data recorded by one of the digital detonators, the acquisition and recording time length of the detector to the vibration record is 0.4 s. It will be appreciated that the acquisition time may be set as desired.
Furthermore, the method can also adopt a circuit breaking detection mode to determine whether the digital detonator detonates, so that the test data corresponding to the test detonator is recorded when the test detonator detonates.
In an implementation manner, the control center comprises an advance forecasting host and a detonation control host, and the detonation control host is in communication connection with the digital detonator initiator to control the digital detonator initiator to detonate. The method controls the digital detonator exploder through the explosion control host, and other control parts are realized by the advanced prediction host, so that the labor division operation of the control center is realized. The advanced forecasting host is used for advanced detection.
To facilitate a general understanding of the above embodiments, a specific implementation scenario is provided below for explanation. In this implementation scenario, including the place that needs to carry out the advanced detection, according to needs, one end in this place is provided with control center 1 and the wave detector of being connected with control center 1 communication, and the wave detector is installed at the position that needs to receive the vibration signal in this place. A plurality of initiation points which need to be detonated by the digital detonators 31 are arranged in the field at the same distance in the Shanghai. The control center 1 comprises an advance forecasting host, wherein a plurality of trigger interfaces are arranged on the advance forecasting host, one of the trigger interfaces is connected with an induction trigger box 21 and a digital detonator initiator 22 through a lead, the induction trigger box 21 is connected with the digital detonator initiator 22 in series, and two ends of the lead are connected to the trigger interfaces to form a first closed circuit, namely a first circuit 2. Other triggering interfaces on the advanced forecasting host are connected with a second closed circuit, namely a second circuit 3, and the second closed circuit is arranged in the sensing hole of the sensing triggering box 21 in a penetrating mode. The number of the second closed circuits is consistent with the number of the detonation points. Each initiation point is provided with a digital detonator 31, and each initiation point can be further provided with an explosive as a seismic source according to needs, wherein the explosive quantity can be selected from 50-100 g.
