Description

Technical Field

[0001] This application relates to the field of electronic detonator testing technology, and in particular to a testing method, apparatus and equipment for electronic detonators. Background Technology

[0002] Electronic detonators, also known as digital electronic detonators, digital detonators, or industrial digital electronic detonators, are electric detonators that use an electronic control unit to control the detonation process. Currently, after production, electronic detonators require non-destructive full inspection of the circuitry. During the R&D and testing phase, researchers also need to use single-voltage testing instruments to test the detonators. Furthermore, single-voltage testing instruments are required for certification testing in laboratories or experimental institutions. Currently, since most electronic detonators operate in a single-voltage mode, single-voltage testing instruments only need one operating voltage mode. However, the latest electronic detonator standards stipulate that electronic detonators require two operating voltages: a low voltage for communication testing and a high voltage for charging and detonation. Existing single-voltage testing instruments only have one voltage operating mode, which cannot meet the requirements for dual-voltage communication testing. Testing requires two single-voltage testing instruments with different operating voltages, significantly reducing testing efficiency. Summary of the Invention

[0015] Please see Figure 1 , Figure 1 This is a schematic block diagram of an electronic detonator detection circuit provided in an embodiment of this application. Figure 1 As shown, the detection circuit of the electronic detonator 200 includes: a main control unit 11, a communication unit 12, a current detection unit 13, a dual voltage switching unit 14, and an interface unit 15. The first end of the interface unit 15 is used to connect to the electronic detonator 200. The second end of the interface unit 15 is connected to the first end of the communication unit 12 and the first end of the current detection unit 13, respectively. The first end of the dual voltage switching unit 14 is connected to the third end of the communication unit 12 and the third end of the current detection unit 13, respectively. The third end of the current detection unit 13 is also connected to the main control unit 11. The second end of the dual voltage switching unit 14 is connected to the main control unit 11.

[0016] Please see Figure 2 , Figure 2 This is a schematic flowchart illustrating a method for detecting an electronic detonator according to an embodiment of this application. Figure 2 The detection method of the electronic detonator shown is executed by the main control unit 11 of the electronic detonator detection circuit 100. The specific steps of the method include: S101-S106.

[0017] S101, the control communication unit 12 and the dual voltage switching unit 14 operate in the first detection mode, wherein, in the first detection mode, the communication unit 12 outputs the first voltage to the electronic detonator 200.

[0018] For example, the main control unit 11 controls the dual-voltage switching unit 14 to output a first voltage, so that the electronic detonator 200 detection circuit and the electronic detonator 200 enter a first detection mode. In the first detection mode, the dual-voltage switching unit 14 outputs a first voltage of 12V to the communication unit 12. The first voltage is the default output voltage of the electronic detonator 200 detection circuit, and the communication unit 12 provides the first voltage to the electronic detonator 200 through the interface unit 15.

[0019] S102. After the current detection unit 13 detects that the electronic detonator 200 is connected, the current detection unit 13 verifies whether the positive or negative current of the electronic detonator 200 is within the normal range.

[0020] For example, the current detection unit 13 begins to detect the current change of the interface unit 15 in real time to determine whether an electronic detonator 200 is connected. The communication unit 12 enters standby mode, preparing to establish communication with the connected electronic detonator 200. The display unit displays the system ready status, awaiting further instructions from the operator. This initialization process ensures that all parts of the system are in optimal working condition, laying the foundation for subsequent multi-voltage detection.

[0021] After the current detection unit 13 detects the connection of the electronic detonator 200, it checks whether the positive or negative current of the electronic detonator 200 is within the normal range and uploads the detection data to the main control unit 11. If the main control unit 11 detects an abnormal positive or negative current, it will immediately alarm and interrupt the detection process to prevent potential damage. If the positive or negative current is normal, the main control unit 11 proceeds to the next stage of detection. Simultaneously, the main control unit 11 controls the display unit to update the display information, indicating to the operator that the electronic detonator 200 has been successfully connected and passed the initial current detection. This step not only ensures the correct connection of the electronic detonator 200 but also provides a safety guarantee for subsequent multi-voltage detection.

[0022] S103. If the verification is successful, the basic parameters of the electronic detonator 200 are obtained, and based on the basic parameters, the communication unit 12 and the current detection unit 13 are controlled to perform communication verification on the electronic detonator 200 to obtain communication verification data.

[0023] For example, if the verification is successful, the main control unit 11 generates a read command, and the communication unit 12 forwards the read command to the electronic detonator 200 to obtain the basic parameters of the electronic detonator 200, including version, ID information, and key parameter detection indicators. This information is transmitted to the main control unit 11 for recording and analysis. Subsequently, the main control unit 11 generates a communication verification command to verify the key parameters inside the electronic detonator 200, such as the MOS performance status parameters, bridge wire status parameters, and capacitor status parameters, according to the key parameter detection indicators.

[0024] During the testing process, the main control unit 11 continuously monitors the communication quality to ensure stable and reliable communication in the first testing mode. If any abnormality is detected during this process, the main control unit 11 will record detailed information and alert the operator. This step not only verifies the communication function of the electronic detonator 200 in the first testing mode but also collects important basic data to prepare for subsequent testing in the second testing mode.

[0025] S104, the control communication unit 12 and the dual voltage switching unit 14 operate in the second detection mode, wherein, in the second detection mode, the communication unit 12 outputs a second voltage to the electronic detonator 200, and the second voltage is greater than the first voltage.

[0026] For example, after completing the task in the first detection mode, the main control unit 11 prepares to switch to the second detection mode. First, the main control unit 11 sends a switching command to the dual-voltage switching unit 14. After receiving the command, the dual-voltage switching unit 14 adjusts the output voltage to the second voltage. During the voltage adjustment process, the main control unit 11 monitors the current change in real time through the current detection unit 13 to ensure a safe and stable voltage switching process. At the same time, the main control unit 11 controls the communication unit 12 to suspend communication to prevent communication errors that may occur during the voltage switching process. When the voltage stabilizes, the main control unit 11 checks the status of each unit again to ensure normal operation in the new voltage mode. The display unit updates the display information to prompt the operator that the system has successfully switched to the second detection mode. This step achieves a smooth transition from low voltage to high voltage, creating conditions for subsequent high-voltage detection.

[0027] S105. In the second detection mode, the control communication unit 12 and the current detection unit 13 perform charge and discharge verification on the electronic detonator 200 to obtain charge and discharge verification data.

[0028] For example, communication unit 12 re-establishes communication with electronic detonator 200 under the second voltage and reads the verification status of electronic detonator 200 to verify whether communication is normal in high-voltage mode. After re-establishing communication, main control unit 11 performs discharge verification. By controlling the internal circuit of electronic detonator 200, it simulates the discharge process in actual use. At the same time, the current verification unit accurately measures the discharge current to ensure that it is within the normal range. After the discharge verification is completed, main control unit 11 performs charging current verification, simulating the charging process of electronic detonator 200 and monitoring whether the charging current meets expectations. Throughout the high-voltage verification process, main control unit 11 continuously monitors various parameters, including voltage stability, current change, and communication quality, to comprehensively evaluate the performance of electronic detonator 200 in high-voltage environment. If any abnormality is detected, main control unit 11 will immediately record and alarm. This step comprehensively verifies the various performance indicators of electronic detonator 200 in high-voltage mode.

[0029] S106. Analyze the communication verification data and charge / discharge verification data according to the preset performance analysis algorithm, and output a test report.

[0030] For example, the main control unit 11 comprehensively processes all the data collected in the preceding steps, including communication verification data from the first detection mode, basic information of the electronic detonator 200, and charge / discharge verification data from the second detection mode. The main control unit 11 uses a preset performance analysis algorithm to analyze this data, evaluate the overall performance and reliability of the electronic detonator 200, and generate a detailed test report. Finally, the main control unit 11 controls the display unit to display the test results in chart or text format, including specific values ​​for each indicator, the pass / fail determination, and potential problem prompts. If a serious problem is found during the test, the main control unit 11 will issue a clear warning. This step not only provides comprehensive test results but also provides a strong basis for the quality control and subsequent improvement of the electronic detonator 200.

[0031] This application provides a method for detecting an electronic detonator, applied to the main control unit of an electronic detonator detection circuit. The electronic detonator detection circuit further includes: a communication unit, a current detection unit, and a dual-voltage switching unit. A first terminal of the interface unit is connected to the electronic detonator. A second terminal of the interface unit is connected to both the first terminal of the communication unit and the first terminal of the current detection unit. A first terminal of the dual-voltage switching unit is connected to both the third terminal of the communication unit and the third terminal of the current detection unit. The third terminal of the current detection unit is also connected to the main control unit. A second terminal of the dual-voltage switching unit is connected to the main control unit. The method includes: controlling the communication unit and the dual-voltage switching unit to operate in a first detection mode, wherein in the first detection mode, the communication unit outputs a first voltage to the electronic detonator; and when current flows through... After the detection unit detects the electronic detonator being connected, it verifies whether the positive or negative current of the electronic detonator is within the normal range through the current detection unit. If the verification is successful, it acquires the basic parameters of the electronic detonator and, based on these parameters, controls the communication unit and the current detection unit to perform communication verification on the electronic detonator, obtaining communication verification data. It then controls the communication unit and the dual-voltage switching unit to operate in the second detection mode, where the communication unit outputs a second voltage to the electronic detonator, which is greater than the first voltage. In this second detection mode, it controls the communication unit and the current detection unit to perform charge-discharge verification on the electronic detonator, obtaining charge-discharge verification data. Finally, it analyzes the communication verification data and the charge-discharge verification data according to a preset performance analysis algorithm and outputs a detection report. In the above method, the combination of the first detection mode (low voltage) and the second detection mode (high voltage) enables comprehensive testing of electronic detonators under different operating voltages, improving the comprehensiveness and accuracy of the testing. Before high-voltage testing, low-voltage testing and current verification are performed first to ensure that the detonator is correctly connected and working properly, reducing the safety risks of high-voltage testing. The entire testing process is automatically controlled by the main control unit, including voltage switching, communication verification, and charge / discharge verification, reducing human error and improving testing efficiency. Through a preset performance analysis algorithm, the acquired communication verification data and charge / discharge verification data are comprehensively analyzed to comprehensively evaluate the performance of the electronic detonator and output a test report, which allows operators to intuitively understand the test results and is beneficial for quality control and subsequent improvements.

[0032] To more clearly illustrate the technical solution of this application, the technical solution of this application will be described below through specific embodiments. It should be noted that the specific embodiments are used to expand the description of the technical solution of this application, and are not intended to limit this application.

[0033] In some embodiments, please refer to Figure 3 , Figure 3 This is a circuit diagram of an electronic detonator detection circuit provided in an embodiment of this application.

The first voltage control unit 141 includes: a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a first capacitor C1, a second capacitor C2, a third capacitor C2, a fourth capacitor C4, a fifth capacitor C5, a sixth capacitor C6, a seventh capacitor C7, an eighth capacitor C8, a ninth capacitor C9, a first inductor L1, a second inductor L2, and a third inductor L3. The VPOS pin is connected to the first terminal of the first resistor R1, the first terminal of the first capacitor C1, the first terminal of the second capacitor C2, and the first terminal of the first inductor L1. The second terminal of the first inductor L1 is connected to the first terminal of the third capacitor C2 and the first terminal of the fourth capacitor C4. The second terminal of the second capacitor C2 is grounded. The second terminal of the first inductor L1 is the positive voltage output terminal. The second terminal of the second capacitor C2 is also connected to the second terminals of the third capacitor C2 and the fourth capacitor C4. The FBP pin is connected to the first terminal VK1 of the second voltage control unit 142, the second terminal of the first resistor R1, the second terminal of the first capacitor C1, and the first terminal of the second resistor R2. The second terminal of the second resistor R2 is grounded. The VREF pin is connected to the second terminal VK2 of the second voltage control unit 142, the first terminal of the third resistor R3, and the first terminal of the fifth capacitor C5. The second terminal of the fifth capacitor C5 is grounded. The FBN pin is connected to the second terminal of the third resistor R3, the third terminal VK3 of the second voltage control unit 142, the first terminal of the sixth capacitor C6, and the first terminal of the fourth resistor R4. The second terminal of the sixth capacitor C6 is connected to the first terminal of the fifth resistor R5, and the second terminal of the fifth resistor R5 is connected to the second terminal of the fourth resistor R4. The second terminal of the fifth resistor R5 is also connected to the VNEG pin. The OUTN1 and OUTN2 pins are connected. The OUTN2 pin is connected to the first terminal of the second inductor L2 and the cathode of the first diode. The anode of the first diode is connected to the second terminal of the fifth resistor R5, the first terminal of the seventh capacitor C7, and the first terminal of the third inductor L3. The second terminal of the third inductor L3 is connected to the first terminal of the eighth capacitor C8 and the first terminal of the ninth capacitor C9. The second terminal of the third inductor L3 is the negative voltage output terminal. The second terminal of the seventh capacitor C7 is connected to the second terminals of the eighth capacitor C8 and the ninth capacitor C9. The second terminal of the seventh capacitor C7 is grounded. The MBUS_HL pin is connected to the controlled terminal of the second voltage control unit 142.

[0034] When the main control unit 11 is used to control the communication unit 12 and the dual voltage switching unit 14 to operate in the first detection mode, it specifically performs the following: outputs a disconnect control signal to the second voltage control unit 142 through the MBUS_HL pin to make the second voltage control unit 142 non-operating; controls the output voltage of the VPOS pin to gradually increase from 0V, and when the voltage of the FBP pin is detected to be a preset first comparison voltage, the output voltage of the VPOS pin is a first positive voltage; controls the common output voltage of the VNEG pin, OUTN1 pin, and OUTN2 pin to gradually decrease from 0V, and when the voltage of the FBN pin is detected to be a preset second comparison voltage, the common output voltage of the VNEG pin, OUTN1 pin, and OUTN2 pin is a first negative voltage, and the first positive voltage and the first negative voltage constitute the first voltage; wherein, when the dual voltage switching unit 14 outputs the first voltage to the communication unit 12, the communication unit 12 is in the first detection mode.

[0035] For example, the voltage detected by the FBP pin is the voltage at the first terminal of the second resistor R2, that is, the voltage division corresponding to the second resistor R2 in the first resistor R1 and the second resistor R2. The FBP pin compares the voltage at the first terminal of the second resistor R2 with a preset first comparison voltage. When the voltage at the first terminal of the second resistor R2 is less than the first comparison voltage, for example, the first comparison voltage is 1.2V, the first control chip U1 controls the output voltage of the VPOS pin to gradually increase until it detects that the voltage at the first terminal of the second resistor R2 is equal to the first comparison voltage. At this point, the increase in the output voltage of the VPOS pin stops, and the output voltage of the VPOS pin is maintained. The maintained output voltage is a first positive voltage, for example, the first positive voltage is 6V.

[0036] The output voltage of the VREF pin is 1.2V. The voltage detected by the FBN pin is the voltage at the second terminal of the third resistor R3, which is the voltage division corresponding to the third resistor R3 in the comparison between the third resistor R3 and the fourth resistor R4. The FBN pin compares the voltage at the second terminal of the third resistor R3 with a preset second comparison voltage. While comparing the voltage at the second terminal of the third resistor R3 with the preset second comparison voltage, the common output voltage of the VNEG pin, OUTN1 pin, and OUTN2 pin is controlled to gradually decrease from 0V until the voltage at the second terminal of the third resistor R3 is detected to be equal to the second comparison voltage. At this point, the decrease in the common output voltage stops, and the common output voltage is maintained. The maintained common output voltage is the first negative voltage, for example, -6V.

[0037] In some embodiments, please refer to Figure 4 , Figure 4 This is a circuit diagram of a second voltage control unit provided in an embodiment of this application. Figure 4As shown, the second voltage control unit 142 includes: a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, a tenth resistor R10, an eleventh resistor R11, a twelfth resistor R12, a thirteenth resistor R13, a first switch Q1, a second switch Q2, a third switch Q3, a fourth switch Q4, a tenth capacitor C10, and an eleventh capacitor C11. The first terminal of the first switch Q1 is the first terminal VK1 of the second voltage control unit 142. The first terminal of the first switch Q1 is connected to the FBN pin. The second terminal of the first switch Q1 is connected to the first terminal of the sixth resistor R6. The second terminal of the sixth resistor R6 is grounded. The third terminal of the first switch Q1 is connected to the first terminal of the seventh resistor R7. The second terminal of the seventh resistor R7 is connected to a preset voltage source. The fourth terminal of the first switch Q1 is connected to the first terminal of the second switch Q2. The second terminal of the second switch Q2 is grounded. The controlled terminal of the second switch Q2 is connected to the first terminal of the eighth resistor R8, the first terminal of the ninth resistor R9, and the first terminal of the tenth capacitor C10. The second terminal of the ninth resistor R9 is the controlled terminal of the second voltage control unit 142. The first terminal of the third switch Q3 is the second terminal VK2 of the second voltage control unit 142. The first terminal of the third switch Q3 is connected to the VREF pin. The second terminal of the third switch Q3 is connected to the first terminal of the tenth resistor R10. The second terminal of the tenth resistor R10 is the third terminal of the second voltage control unit 142. The third terminal of the third switch Q3 is connected to the first terminal of the eleventh resistor R11. The second terminal of the eleventh resistor R11 is connected to the preset voltage source. The fourth terminal of the third switch Q3 is connected to the first terminal of the fourth switch Q4. The second terminal of the fourth switch Q4 is grounded. The controlled terminal of the fourth switch Q4 is connected to the first terminal of the twelfth resistor R12, the first terminal of the thirteenth resistor R13, and the first terminal of the eleventh capacitor C11. The second terminal of the thirteenth resistor is the controlled terminal of the second voltage control unit 142.

[0038] When the main control unit 11 is used to control the communication unit 12 and the dual-voltage switching unit 14 to operate in the second detection mode, it specifically performs the following: It outputs a connection control signal to the second voltage control unit 142 via the MBUS_HL pin to put the second voltage control unit 142 into operation. When the second voltage control unit 142 is in operation, the first switch Q1, the second switch Q2, the third switch Q3, and the fourth switch Q4 are turned on. The output voltage of the VPOS pin is controlled to gradually increase from a first positive voltage. When the voltage of the FBP pin is detected to be a preset first comparison voltage, the output voltage of the VPOS pin becomes a second positive voltage. The common output voltage of the VNEG pin, OUTN1 pin, and OUTN2 pin is controlled to gradually decrease from a first negative voltage. When the voltage of the FBN pin is detected to be a preset second comparison voltage, the common output voltage of the VNEG pin, OUTN1 pin, and OUTN2 pin becomes a second negative voltage. The second positive voltage and the second negative voltage constitute the second voltage. When the dual-voltage switching unit 14 outputs the second voltage to the communication unit 12, the communication unit 12 is in the second detection mode.

[0039] For example, when the second voltage control unit 142 is in operation, the first resistor R1 and the sixth resistor R6 are connected in parallel, and their common resistance decreases. The FBP pin detects a decrease in the voltage at the first end of the second resistor R2. The first control chip U1 controls the output voltage of the VPOS pin to gradually increase until it detects that the voltage at the first end of the second resistor R2 equals the first comparison voltage. At this point, the increase in the output voltage of the VPOS pin stops, and the output voltage of the VPOS pin is maintained. The maintained output voltage is a second positive voltage, for example, the first positive voltage is 12V. Similarly, the common output voltage of the VNEG pin, OUTN1 pin, and OUTN2 pin is maintained as a second negative voltage, for example, the second negative voltage is -12V.

[0040] It should be noted that the first switch Q1 and the third switch Q3 are optocouplers.

[0041] It should also be noted that after using the dual-voltage switching unit 14, the electronic detonator 200 detection circuit can provide a first voltage of ±6V and a second voltage of ±12V. When the electronic detonator 200 detection circuit outputs the second voltage from the first voltage, the switching between ±6V and ±12V in the electronic detonator 200 cannot achieve optimal communication performance. Therefore, by adjusting the component parameters of the electronic detonator 200 detection circuit, the first positive voltage can be adjusted to +5.2V and the first negative voltage to -3.3V. Furthermore, the second positive voltage can be adjusted to +16V and the second negative voltage to -8V, thereby improving communication stability. In the low-voltage operating mode, the bus voltage is only 8.5V, and the electronic detonator 200 detection circuit needs to provide special voltages of +5.2V and -3.3V for communication.

The component verification data includes: MOS performance parameters, bridge wire parameters and capacitor parameters; obtain the total number of communication attempts and the number of successful communication attempts between the communication unit 12 and the electronic detonator 200, and determine the communication success rate based on the total number of communication attempts and the number of successful communication attempts.

[0043] In some embodiments, when the main control unit 11 is used to execute the second detection mode, controlling the communication unit 12 and the current detection unit 13 to perform charge-discharge verification on the electronic detonator 200 and obtain charge-discharge verification data, it specifically performs the following: sending a discharge verification command to the electronic detonator 200 through the communication unit 12 to cause the electronic detonator 200 to execute a preset discharge simulation process.

The maximum discharge current value and discharge duration are determined based on the discharge current data. Sending a charge verification command to the electronic detonator 200 through the communication unit 12 to cause the electronic detonator 200 to execute a preset charging simulation process. During the execution of the preset charging simulation process by the electronic detonator 200, the charging current data of the electronic detonator 200 is detected by the current detection unit 13, the charging rate is determined based on the charging current data, the charging voltage data of the electronic detonator 200 is obtained through the communication unit 12, the charging stability of the electronic detonator 200 is calculated based on the charging voltage data, and charge and discharge verification data is generated based on the maximum discharge current value, charging duration, charging rate and charging stability.

[0048] S201, Performance Evaluation Matrix Expansion.

[0049] For example, the original performance evaluation matrix E needs to be expanded to include more key parameters. The expanded matrix E' is defined as follows: E'=[D, ID, M, B, C, R, I dmax T d V, S, V th I th T rise T fall F noise ]; Where V is the electronic detonator version number, ID is the electronic detonator ID information, M is the MOS performance parameter, B is the bridge wire parameter, C is the capacitor state, R is the communication success rate, and I... dmax For the maximum discharge current, T d V is the charging duration, V is the charging rate, and S is the voltage stability. th To trigger the threshold voltage, I th To trigger the threshold current, T rise For the rise time, T fall For the descent time, F noise This represents the noise figure.

[0051] For example, the Z-score standardization method is used: Z(x) = (x - μ) / σ. Here, x is the raw value of each parameter, μ is the mean of each parameter, and σ is the standard deviation of each parameter. Applying this formula to each parameter in E' yields the standardized matrix Z: Z = [Z(V), Z(ID), ..., Z(F)]. noise )).

[0053] For example, a weight vector W is introduced: W = [w1, w2, ..., w15], where wi represents the weight of the i-th parameter, and satisfies: Weights can be determined using the Analytic Hierarchy Process (AHP) or expert scoring.

[0054] S204, multi-dimensional scoring.

[0055] For example, based on the multi-dimensional scoring algorithm A2, the comprehensive performance score P is calculated using the following formula: ; Where Z(i) is the i-th element in the standardized matrix Z, wi is the i-th element in the weight vector W, and Z' is the average value of all elements in Z. α, β, and γ are adjustment parameters used to balance the effects of linear combination, geometric mean, and dispersion.

[0057] For example, a performance threshold P is set based on historical data. th Compare the calculated P value with P th By comparison, the mass of an electronic detonator can be preliminarily determined: if P ≥ P th If P is qualified, then it is considered qualified. <P th If it does not meet the requirements, it will be deemed unqualified.

[0058] To achieve more precise classification, fuzzy set theory is introduced, and the membership function μ(P) is defined: The specific calculation formula for the membership function μ(P) is defined as follows: ; Where k is the slope parameter, controlling the steepness of the function. Based on the value of μ(P), electronic detonators can be classified into the following categories: High quality: μ(P) ≥ 0.9; Acceptable: 0.7 ≤ μ(P) < 0.9; Borderline: 0.3 ≤ μ(P) < 0.7; Unacceptable: μ(P) < 0.3.

[0059] S206, Batch quality assessment and identification of nonconforming products.

[0060] For example, for a batch containing n electronic detonators, the overall quality index Q of the batch is calculated using the following formula: ; Where P j This is the performance score of the j-th electronic detonator. Simultaneously, identify defective products in the batch. Define the set of defective products D: D = {j|μ(P jIf 1 ≤ j ≤ n, then the batch rejection rate R is calculated as follows: R = |D| / n, where |D| is the cardinality (number of elements) of set D.
