Description

Technical Field

[0002] At present, with the continuous development of blasting technology, the application of electronic detonators in engineering blasting is becoming more and more extensive. In order to improve the safety and reliability of electronic detonators, the new electronic detonator standard requires that electronic detonators can work in both high-pressure and low-pressure modes. This requirement is intended to adapt to different operating environments and safety requirements and improve the applicability and safety of electronic detonators. However, there are some limitations in the current detonator design. The current detonator arranges the detection tasks in high-pressure and low-pressure modes respectively. This design makes it difficult to complete some detection tasks that require secondary verification after switching between high-pressure and low-pressure modes. This situation may lead to incomplete or inaccurate detection results, thus bringing potential safety hazards. Specifically, some detection tasks completed in high-pressure mode may require secondary verification in low-pressure mode, and vice versa. However, due to the limitations of the current detonator design, this cross-mode secondary verification is difficult to achieve. This not only affects the comprehensiveness and accuracy of the detection, but may also cause some potential safety issues to be ignored or not discovered in time. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0032] It should also be understood that the terms used in this application specification are only for the purpose of describing specific embodiments and are not intended to limit the application. As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0033] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0034] See also Figure 1 , Figure 1 The embodiment of the present application also provides a schematic flow chart of a detonation control method. Figure 1 As shown, the detonation control method is applied to a detonating plate, which is used to communicate with an electronic detonator. The working mode of the detonating plate and the working mode of the electronic detonator both include: a first mode and a second mode. The specific steps of the method include: S201-S206.

[0035] S201. Based on the first mode, perform two-way communication verification with the electronic detonator.

[0036] It should be noted that the first mode is a low voltage mode, for example, the communication voltage between the detonator plate and the electronic detonator is 12V; the second mode is a high voltage mode, for example, the communication voltage between the detonator plate and the electronic detonator is 24V.

[0037] Exemplarily, in the first mode, the detonating plate matches, searches, detects, verifies, etc. the electronic detonator and establishes a communication connection with the electronic detonator.

[0038] S202: After all electronic detonators have completed the two-way communication verification, the first mode is switched to the second mode, and a mode switching instruction is sent to the electronic detonators to make the electronic detonators enter the second mode.

[0039] Exemplarily, after the detonator plate is switched to the second mode, a 24V voltage is provided to the electronic detonator, and a mode switching instruction is sent to the electronic detonator, wherein the mode switching instruction includes mode flag information. After the electronic detonator parses the mode switching instruction to obtain the mode flag information, the mode flag information is saved in the mode flag bit, and the electronic detonator is switched to the second mode corresponding to the mode flag information.

[0040] S203, switching from the second mode to the first mode, broadcasting a mode detection instruction to the electronic detonator of the second mode, and if a first confirmation response is received from the electronic detonator of the second mode, generating a first abnormal prompt and stopping detonation.

[0041] Exemplarily, the detonator immediately switches back to the first mode, broadcasts the mode detection instruction in the first mode, and does not need to return the first response confirmation if the electronic detonator receives the mode detection instruction in the second mode. If the electronic detonator is not in the second mode, the first response confirmation is returned to the detonator. If the detonator receives the first response confirmation, it proves that after switching to the second mode, at least one or more electronic detonators did not receive the instruction normally in the second mode, indicating that the high voltage detection is abnormal and the charging and detonation action is not allowed.

[0042] S204, if the first confirmation response is not received, switch from the second mode to the second mode, charge the electronic detonator in the second mode, and after the electronic detonator in the second mode is fully charged, send an identity detection instruction to make the electronic detonator in the second mode reply with identity authentication information.

[0043] Exemplarily, after detecting that the high voltage state of all electronic detonators is normal, the initiator returns to the second mode, charges the electronic detonators, and performs identity detection with each electronic detonator during the charging process to verify whether the electronic detonator sends identity authentication information normally under high voltage, thereby verifying the communication status of the electronic detonator after charging. Secondary detection of the charged electronic detonator is achieved.

[0044] S205, detecting whether the identity authentication information and the preset identity authentication information all match, if all match, sending a detonation preparation instruction, if receiving a second confirmation response from the electronic detonator of the second mode, generating a second abnormal prompt, and stopping detonation.

[0045] Exemplarily, the identity authentication information includes the identity authentication information of the electronic detonator that is allowed to participate in the detonation task. After completing the above matching. The detonator board sends a detonation preparation instruction to make the electronic detonator enter the detonation preparation state. The electronic detonator detects its own mode flag according to the mode flag information. If the mode flag information and the mode flag are different, a second confirmation response is generated to notify the detonator board of a mode abnormality. The detonator board receives the second confirmation response, stops the detonation procedure, and notifies to perform manual inspection.

[0046] S206: If the second confirmation response is not received, sending a detonation pulse to the electronic detonator of the second mode to control the electronic detonator of the second mode to detonate.

[0047] The embodiment of the present application provides a detonation control method, which is applied to a detonating plate, the detonating plate is used for communication connection with an electronic detonator, the working mode of the detonating plate and the working mode of the electronic detonator both include: a first mode and a second mode, and the method includes: based on the first mode, performing a two-way communication check with the electronic detonator; after all the electronic detonators have completed the two-way communication check, switching from the first mode to the second mode, and sending a mode switching instruction to the electronic detonator to make the electronic detonator enter the second mode; switching from the second mode to the first mode, broadcasting a mode detection instruction to the electronic detonator of the second mode, and generating a first confirmation response if a first confirmation response is received from the electronic detonator of the second mode. An abnormal prompt stops detonation; if the first confirmation response is not received, switch from the first mode to the second mode, charge the electronic detonator in the second mode, and after the electronic detonator in the second mode is charged, send an identity detection instruction to make the electronic detonator in the second mode reply identity authentication information; detect whether the identity authentication information and the preset identity authentication information are all matched, if all match, send a detonation preparation instruction, if the second confirmation response replied by the electronic detonator in the second mode is received, generate a second abnormal prompt, stop detonation; if the second confirmation response is not received, send a detonation pulse to the electronic detonator in the second mode, and control the electronic detonator in the second mode to detonate. Through the above method, flexible switching between the first mode and the second mode realizes comprehensive detection and verification of the electronic detonator, not only ensures the reliability of two-way communication, but also verifies whether the mode conversion of the electronic detonator is correct through the mode switching instruction and the detection instruction. At the same time, through the double verification of identity detection and detonation preparation instruction, the safety of the detonation process is further improved. This multiple detection and verification mechanism significantly reduces the risk of misoperation and equipment failure, effectively improves the overall reliability and safety of the electronic detonator initiation system, and provides more reliable technical support for engineering blasting operations.

[0048] In order to more clearly introduce the technical solution of the present application, the technical solution of the present application will be introduced through specific embodiments below. It should be noted that the specific embodiments are used to expand the technical solution of the present application, but are not intended to limit the present application.

[0049] See also Figure 2 , Figure 2 The schematic block diagram of the first detonation plate provided in the embodiment of the present application is shown. Figure 2 As shown, the detonation board 200 includes: a receiving circuit 100. The receiving circuit 100 includes: a pressure relief unit 11, a first operational amplifier unit 12, a second operational amplifier unit 13, a comparison unit 14 and a main control unit 15. Figure 1 The detonation control method is applied to the main control unit 15.

[0050] The first end of the pressure relief unit 11 is used to connect to the electronic detonator 300 to receive the interactive signal sent by the electronic detonator 300 and execute the detonation control method as any one of the embodiments of the present application.

[0051] It should be noted that when the main control unit 15 communicates and interacts with the electronic detonator 300, instructions or signals are sent to the electronic detonator 300 through a sending circuit, and the sending circuit is only briefly shown in the figure.

[0052] A first end of the first operational amplifier unit 12 is connected to a second end of the pressure relief unit 11 , and the first operational amplifier unit 12 is used to amplify the interactive signal to generate a primary amplified signal.

[0053] A first end of the second operational amplifier unit 13 is connected to a second end of the first operational amplifier unit 12 , and the second operational amplifier unit 13 is used to filter and amplify the primary amplified signal to generate a secondary amplified signal.

[0054] The first end of the comparison unit 14 is connected to the second end of the second operational amplifier unit 13, and the voltage input end of the comparison unit 14 is connected to the preset positive voltage signal. The comparison unit 14 is used to receive the secondary amplified signal and generate a communication signal according to the secondary amplified signal and the preset positive voltage signal (MBUS-+12V).

[0055] The main control unit 15 is connected to the second end of the comparison unit 14 and is used to communicate and interact with the electronic detonator 300 according to the communication signal.

[0056] When the detonating plate 200 switches from the second mode to the first mode, the main control unit 15 sends a conduction instruction to the pressure relief unit 11 to make the pressure relief unit 11 enter a conduction state to discharge the residual voltage at the first end of the first operational amplifier unit 12 .

[0057] By means of the receiving circuit 100 , the stability of the detonating plate 200 during the mode switching process is improved, the reaction time of the mode switching is reduced, and the probability of misdetection is also reduced.

[0058] In some embodiments, see Figure 3 , Figure 3The schematic block diagram of the second detonation plate provided in the embodiment of the present application is shown. Figure 3 As shown, the receiving circuit 100 further includes: a voltage stabilizing unit 16, the input end of the voltage stabilizing unit 16 is connected to the second end of the comparison unit 14, and the output end of the voltage stabilizing unit 16 is connected to the main control unit 15. After receiving the communication signal, the voltage stabilizing unit 16 performs voltage stabilization processing on the communication signal to obtain a communication voltage stabilization signal, and sends the communication voltage stabilization signal to the main control unit 15.

[0059] The voltage stabilizing unit is used to prevent the comparison unit from outputting an excessively large voltage, thereby preventing the main control unit from being broken down and improving the safety of the circuit.

[0060] In some embodiments, see Figure 4 , Figure 4 The circuit diagram of a pressure relief unit provided in an embodiment of the present application is shown. Figure 4 As shown, the pressure relief unit 11 includes: a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, a first diode D1, a second diode D2, a third diode D3, a first switch tube Q1, a first capacitor C1 and a second capacitor C2.

[0061] The anode of the first diode D1 is the first end of the pressure relief unit 11, the anode of the first diode D1 is used to connect to the electronic detonator 300, the second end of the first diode D1 is respectively connected to the first end of the third resistor R3, the cathode of the second diode D2, the first end of the sixth resistor R6, the first end of the first capacitor C1, and the first end of the seventh resistor R7, the second end of the third resistor R3 is connected to the first end of the first switch tube Q1, the controlled end of the first switch tube Q1 is connected to the first end of the first resistor R1, the second end of the first resistor R1 is connected to the conduction control end of the main control unit 15, the first end of the first resistor R1 is also respectively connected to the first end of the second resistor R2, and the second end of the second resistor R2 is respectively The second end of the fourth resistor R4 is connected to the second end of the first switch tube Q1, the first end of the fourth resistor R4, and the ground end. The second end of the fourth resistor R4 is respectively connected to the anode of the second diode D2, the first end of the second capacitor C2, and the first end of the fifth resistor R5. The second end of the second capacitor C2 is grounded. The second end of the fifth resistor R5 is connected to the preset positive voltage signal (MBUS-+12V). The second end of the sixth resistor R6 is grounded. The second end of the first capacitor C1 is respectively connected to the second end of the seventh resistor R7 and the first end of the eighth resistor R8. The second end of the first capacitor C1 is the second end of the pressure relief unit 11. The second end of the eighth resistor R8 is connected to the anode of the third diode D3, and the cathode of the third diode D3 is grounded.

[0062] When the conduction control terminal outputs a conduction instruction, the first switch tube Q1 enters a conduction state, so that the residual voltage of the cathode of the first diode D1 is consumed and removed by the third resistor R3.

[0063] During the test, it was found that the receiving circuit 100 could not process signals within 10s-20s after switching from the second mode to the first mode. The reason is that in the second mode, the signal fed back by the electronic detonator 300 is always a high voltage. When switching to the first mode, the residual voltage cannot be released due to the obstruction of the first diode D1, resulting in the need to wait for the residual voltage to be slowly released before correct signal processing can be performed. Therefore, the first switch tube Q1 is added, and after the mode is switched, the first switch tube Q1 is turned on, and the residual voltage is discharged through the third resistor R3, so that the second mode can be quickly switched to the first mode.

[0064] In some embodiments, see Figure 5 , Figure 5 The circuit diagram of a first operational amplifier unit provided in an embodiment of the present application is shown. Figure 5 As shown, the first operational amplifier unit 12 includes: a ninth resistor R9, a tenth resistor R10, an eleventh resistor R11, a twelfth resistor R12, a thirteenth resistor R13, a fourteenth resistor R14, a fifteenth resistor R15, a third capacitor C3, a fourth capacitor C4, a fifth capacitor C5, a sixth capacitor C6, a seventh capacitor C7, an eighth capacitor C8 and a first amplifier U1.

[0065] The first end of the ninth resistor R9 is the first end of the first operational amplifier unit 12, the first end of the ninth resistor R9 is connected to the second end of the pressure relief unit 11, the second end of the ninth resistor R9 is respectively connected to the first end of the third capacitor C3, the first end of the tenth resistor R10, and the non-inverting input end of the first amplifier U1, the inverting input end of the first amplifier U1 is respectively connected to the first end of the twelfth resistor R12, the first end of the fourteenth resistor R14, and the first end of the fourth capacitor C4, the second end of the twelfth resistor R12 is respectively connected to the first end of the fifth capacitor C5, the first end of the sixth capacitor C6, and the ground end, the second end of the fifth capacitor C5 is respectively connected to the second end of the sixth capacitor C6, the negative power input end of the first amplifier U1, the The first end of the thirteenth resistor R13 is connected, the second end of the thirteenth resistor R13 is connected to the preset negative voltage signal (MBUS--12V), the positive power input end of the first amplifier U1 is respectively connected to the first end of the eleventh resistor R11, the first end of the seventh capacitor C7, and the first end of the eighth capacitor C8, the second end of the eleventh resistor R11 is connected to the preset positive voltage signal (MBUS-+12V), the second end of the seventh capacitor C7 and the second end of the eighth capacitor C8 are both grounded, the output end of the first amplifier U1 is respectively connected to the second end of the fourth capacitor C4, the second end of the fourteenth resistor R14, and the first end of the fifteenth resistor R15, and the second end of the fifteenth resistor R15 is the second end of the first operational amplifier unit 12.

[0066] When the electronic detonator 300 sends an interactive signal to the receiving circuit 100, it is realized by pulling down the voltage of the non-inverting input terminal of the first amplifier U1. When the voltage of the non-inverting input terminal of the first amplifier U1 is less than the preset positive voltage signal (MBUS-+12V), the output terminal of the first amplifier U1 outputs a high level. Since the pulled-down voltage is small, the interactive signal of the electronic detonator 300 needs to be amplified once by the first operational amplifier unit 12.

[0069] The first amplified signal is filtered and amplified twice by the second operational amplifier unit 13 to obtain a secondary amplified signal, so as to improve the signal accuracy in the signal transmission process.
