Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of 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 some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
At present, a wireless communication mode is adopted to control the triggering and the detonation of the electronic detonator, so that the synchronism of the wireless communication is poor, and the blasting effect is influenced.
In view of the foregoing, there is provided in accordance with an embodiment of the invention a wireless electronic detonator initiation control method embodiment, it being noted that the steps illustrated in the flow chart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that, although a logical sequence is illustrated in the flow chart, in some cases, the steps illustrated or described may be performed in a different order than that illustrated herein.
In this embodiment, a wireless electronic detonator initiation control method is provided, which may be used in an initiation controller to control electronic detonator initiation, and fig. 1 is a flowchart of a wireless electronic detonator initiation control method according to an embodiment of the present invention, and as shown in fig. 1, the flowchart includes the following steps:
step S101, a calibration signal is sent to a plurality of electronic detonators which are in wireless connection with the detonation controller, and the calibration signal is used for calibrating clocks of the electronic detonators.
The wireless modules are arranged in the detonation controller and the electronic detonators, and the detonation controller is simultaneously in wireless connection with a plurality of electronic detonators, namely, the wireless detonation controller simultaneously controls a plurality of wireless electronic detonators, which can be shown by referring to fig. 2.
In this embodiment, the initiation controller and the electronic detonator may be connected by a single shot test clip prior to transmitting the calibration signal. And then the detonation controller is used for sending a pulse wave of 1 second to serve as a calibration signal to the electronic detonator, and the electronic detonator automatically calibrates an external clock according to the second pulse sent by the detonation controller. By means of wired single-shot detection, all deviation of external timers of the wireless electronic detonators is corrected, and accuracy of clocks can be effectively guaranteed.
With respect to clock calibration, due to temperature or manufacturing process effects, possible deviations of the clock oscillator are difficult to eliminate, resulting in errors in clock timing of the electronic detonator. In this embodiment, the clock may be calibrated by counting, for example: the pulse wave of 1 second comprises 1000 rising edge signals, 998 rising edges are read in 1S by the electronic detonator 1, 999 rising edges are read in 1S by the electronic detonator 2, so that the timing error of the electronic detonator can be counted according to the counting of the electronic detonator by calculation, the corresponding electronic detonator clock is compensated according to the timing error, and the calibration of the electronic detonator clock is realized.
And step S102, writing reference time into the electronic detonators to synchronize clocks of all the electronic detonators and trigger the detonation controller and a timer of the electronic detonators to count, wherein the reference time is the current time of control equipment connected with the detonation controller.
In this embodiment, the reference time is also written into the electronic detonator by using a single-shot detection mode, so as to ensure the accuracy of the clock of the electronic detonator. The control device may be a short range slave unit connected to the explosion controller, the short range slave unit may be a handset, and after the external clock of the electronic detonator is calibrated, each electronic detonator may be written in with the current time of the handset as a reference time, so as to ensure that clocks of all electronic detonators are in a synchronous state. After the reference time is written, the external high-precision timer of the electronic detonator starts to count, and the power module of the electronic detonator starts to supply power. Wherein the clock of the electronic detonator may provide a more accurate time reference to ensure that the explosion occurs within a predetermined time, and an external timer may be used to set the delay time of the explosion.
Step S103, a wireless detection signal is sent to the electronic detonator so as to detect a timer value of the electronic detonator, wherein the timer value is a time difference value from a reference time to a detection time, and the detection time is the time when the electronic detonator receives the wireless detection signal.
After writing the reference time into the electronic detonator, the detonation controller sends a wireless detection signal, namely a detection instruction to the electronic detonator, the wireless electronic detonator replies the value of an external timer of the wireless electronic detonator after receiving the instruction, the wireless detonation controller can judge whether the wireless electronic detonator works normally or not and whether the timing is accurate or not according to the received timer value, and the timer value can be the time difference value from the written reference time to the wireless detection signal.
Because clock calibration and reference time writing are both carried out by adopting a single-shot detection mode, the first shot is recorded at 12 points, and the nth shot is about to be 14 points, whether the wireless electronic detonator works normally or not can be judged by sending a wireless detection signal, timing is accurate or not, and the like, so that the electronic detonator can be ensured to detonate normally.
Step S104, under the condition that the timer value of each electronic detonator is consistent with the timing time of the detonation controller, a detonation control instruction is sent to control the electronic detonators to detonate after the preset time.
After the detonation controller receives the timer value fed back by the electronic detonator, the timer value can be compared with the self-timing timer of the detonation controller, wherein the self-timing time of the detonation controller can be the time difference between the reference time and the wireless detection signal. When the phase difference between the timer value and the timing time is within a preset range, such as 0-1ms, the timer value is determined to be consistent with the timing time.
After the wireless electronic detonator timing is determined to be correct, the functions of electronic detonator detection, timing and the like can be performed, the wireless electronic detonator returns a current state value and a timing value, the detonation controller judges whether the wireless electronic detonator is normal or not according to the received state value, and next operation is performed after the wireless electronic detonator timing is correct, namely a detonation control instruction is sent to all the electronic detonators. The control instruction comprises the predicted detonation time, so that the electronic detonator can be controlled to detonate after the preset time.
In the embodiment, all the electronic detonator clocks are calibrated through the calibration signals so as to ensure the accuracy of the electronic detonator clocks; after the clock is calibrated, all the wireless electronic detonators take the same time as a reference and are detonated by appointed time, so that the method ensures that all the wireless electronic detonators can be detonated at the same time, has synchronism, further ensures blasting effect and has higher reliability.
Further, the wireless detonation avoids the wired defects, reduces wiring time, is not influenced by terrain any more, reduces bus expenditure, and reduces cost.
In some alternative embodiments, the calibration signal is sent by means of single shot detection and the reference time is written to the electronic detonator;
after writing the reference time to the electronic detonator, comprising: and confirming whether the wireless communication between the detonation controller and the electronic detonator is normal or not.
The single shot detection mode of the electronic detonator refers to that the detonation controller and the electronic detonator are connected one by one through the single shot test clamp so as to perform wired single shot test on the electronic detonator, and the clock of the electronic detonator can be calibrated and the reference time can be written into the electronic detonator through the wired single shot detection mode.
Because clock calibration and reference time writing are both performed in a single-shot detection mode, whether wireless communication between the detonation controller and the electronic detonator is normal or not needs to be confirmed in order to ensure that the electronic detonator can be detonated normally under the condition of wireless control, and detection signals are sent to the electronic detonator in a wireless mode under the condition that the wireless communication is normal so as to detect the timer value of the electronic detonator.
In this embodiment, the accuracy of the clock of the electronic detonator can be more effectively ensured by adopting the single-shot detection mode to send the calibration signal and writing the reference time into the electronic detonator. Further, whether wireless communication between the detonation controller and the electronic detonator is normal or not is determined, and reliability of the detonation controller and the electronic detonator can be ensured.
In some alternative embodiments, before sending the initiation control instruction, the method further comprises:
step S201, judging the wireless communication quality between the detonation controller and the electronic detonator;
step S202, when the wireless communication quality is good or bad, the communication frequency band is automatically switched.
The wireless electronic module which is written in can be subjected to hole filling, namely the detonation controller and the electronic detonator are filled. Before the detonation controller sends the detonation control instruction, the wireless communication quality between the wireless detonation controller and the wireless electronic detonator can be tested by utilizing the wireless electronic module, the wireless detonation controller can automatically switch the frequency band through judging the wireless communication quality, the undisturbed frequency band is selected, and the reliability of wireless communication is ensured.
In some optional embodiments, the step S201, determining the quality of wireless communication between the detonation controller and the electronic detonator includes:
step S2011, a communication test instruction of a first preset number of times is sent to the electronic detonator at a preset communication frequency.
Step S2012, receiving a communication feedback signal of the electronic detonator.
In step S2013, in the case that the number of times of the received communication feedback signal is higher than the second preset number of times, it is determined that the wireless communication quality of the corresponding preset communication frequency is excellent.
The electronic detonators may be first subjected to communication detection at an initial fixed communication frequency set by the wireless initiation controller, for example, 50 communication test instructions may be simultaneously sent to each electronic detonator. And after the electronic detonator receives the communication test instruction, feeding back a communication feedback signal to the detonation controller. And the detonation controller determines the feedback times of the received communication feedback signals, and if the feedback times of each electronic detonator are higher than 48 times, the communication frequency quality is determined to be excellent.
In some optional embodiments, the step S201, determining the quality of wireless communication between the detonation controller and the electronic detonator includes:
step S2014, when the number of times of the received communication feedback signals is within the preset range, determining that the wireless communication quality of the corresponding preset communication frequency is good, changing the preset communication frequency, and sending the communication test instruction of the first preset number of times to the electronic detonator again.
Still taking the above example as an example, if the feedback frequency of each electronic detonator is 47-40, determining that the communication frequency quality is good, recording the frequency band and the successful communication frequency, and performing frequency hopping communication with a fixed step value, for example, 10M, and the superposition value is 200M at maximum. If the period has excellent communication frequency, the communication is carried out at the frequency, if the period is not excellent, the recorded good frequency band is compared, and the communication frequency with better quality is compared.
In some optional embodiments, the step S201, determining the quality of wireless communication between the detonation controller and the electronic detonator includes:
in step S2015, if the number of times of the received communication feedback signal is less than the third preset number of times, determining that the wireless communication quality of the corresponding preset communication frequency is poor, rejecting the corresponding preset communication frequency, changing the preset communication frequency, and sending the communication test instruction of the first preset number of times to the electronic detonator again.
Still taking the above example as an example, if the feedback frequency of each electronic detonator is lower than 40, determining that the quality of the communication frequency is poor, recording the frequency band and marking to reject the communication frequency. And frequency hopping communication is performed with a fixed step value, for example, 10M, and the superimposed value is 200M at the maximum. If the period has excellent communication frequency, the communication is carried out at the frequency, if the period is not excellent, the recorded good frequency band is compared, and the communication frequency with better quality is compared. If all the signals are bad, the wireless communication quality is low, and attention is paid to the influence of surrounding environment, so that the interference of a fixed frequency band can be effectively avoided.
In this embodiment, the wireless initiation controller may determine whether the wireless communication quality is good or bad by communicating with the wireless electronic detonator, and automatically frequency-hopping, and select the frequency band communication with the best wireless communication quality, so as to ensure the reliability of the wireless communication.
In some alternative embodiments, prior to sending the initiation control instruction, comprising:
and sending a high-voltage charging instruction to the electronic detonator to charge the detonation capacitor in the electronic detonator so as to be used for detonating the explosive.
After all the electronic detonators are determined to be communicated and timed correctly, the wireless detonation controller sends a high-voltage charging instruction and enters a detonation interface so as to ensure that the electronic detonators can normally detonate explosives and improve detonation reliability.
In some alternative embodiments, the initiation control instructions comprise: the password time and the countdown time are marked.
The cipher time is the set value of the timer inside the detonation controller. For example, the password-scratching time is T0, and the wireless initiation controller counts down for 5S and initiates after password scratching. At this time, the wireless initiation controller sends out a pre-initiation command, which includes initiation time T. T=t0+5s. After receiving the instruction, the wireless electronic detonator returns to the state value and locks, no data is received any more, and the detonation of the wireless electronic detonator is ensured not to be affected by any interference. And starts to wait for the time T and detonate at the same time according to the time value of the external timer.
In the embodiment, all the wireless electronic detonators take the time of the wireless detonation controller as a reference, and the time T is contracted for detonation, so that the same time detonation of all the wireless electronic detonators is ensured, and the blasting effect is ensured.
