Terms (such as those defined in commonly used dictionaries) shall be interpreted as having the same meaning as in their contextual meaning in the relevant technical field and shall not be construed as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this application.

[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] Typically, in existing blasting processes, multiple locations need to be detonated sequentially to control the collapse direction of the blasted object. When a certain location is detonated, it can easily cause circuit breaks or abnormalities in other undetonated locations, leading to the failure of the blasting mission and potentially causing serious consequences.

[0042] Therefore, in order to enhance the reliability and stability of detonator circuits, this application proposes an electronic detonator circuit to solve the above problems.

[0043] Please refer to Figure 1 This is a schematic diagram of an electronic detonator circuit proposed in an embodiment of this application. Exemplarily, this electronic detonator circuit is applied in a detonator.

[0044] In some embodiments, the electronic detonator circuit includes: a control module 110, a voltage regulator module 120, a first conduction module 130, an energy storage module 140, a detonation module 150, and a second conduction module 160; the voltage regulator module 120 and the first conduction module 130 are connected, and both connection terminals are configured to be connected to a first power supply voltage VCC; the voltage regulator module 120 is also connected to the control module, the control module 110 is respectively connected to the first conduction module 130 and the second conduction module 160, the first conduction module 130 is also respectively connected to the energy storage module 140 and the detonation module 150, and the detonation module 150 is also connected to the energy storage module 140 and the second conduction module 160.

[0045] Specifically, the voltage regulator module 120 transmits the regulated first power supply voltage VCC to the control module 110 to power the control module 110. The control module 110 outputs a first turn-on signal and a first turn-off signal to control the first turn-on module 130 to turn on and off. The control module 110 also outputs a second turn-on signal and a second turn-off signal to control the second turn-on module 160 to turn on and off. When the first turn-on module 130 is on, the input first power supply voltage VCC is transmitted to the energy storage module 140 to charge it, and simultaneously transmitted to the detonation module 150. The energy storage module 140 is also connected to the detonation module 150. The detonation module 150 has two ends. When the signals at both ends of the detonation module 150 reach a certain value, the detonation module 150 will detonate. Since the detonation module 150 is close to the external gunpowder, when the detonation module 150 detonates, it ignites the external gunpowder.

[0046] Alternatively, the control module 110 can be selected as a 32-bit low-power microcontroller.

[0047] In some embodiments of the electronic detonator circuit, the following are also included:

[0048] When the control module 110 receives the start signal, it sends a first turn-on signal to the first turn-on module 130 to turn on the first turn-on module 130. After the first turn-on module 130 is turned on, the first power supply voltage VCC charges the energy storage module 140.

[0049] Specifically, firstly, please combine Figures 1 to 3 When the external first power supply voltage VCC is connected, it supplies power to the voltage regulator module 120. The voltage regulator module 120 adjusts the first power supply voltage VCC to obtain a second power supply voltage, and provides electrical signal energy to the control module 110 through the power supply port V_MCU, so that the control module 110 can work continuously. When the control module 110 receives an enable signal, it transmits a first conduction signal to the first conduction module 130 through the first output port GPIO1. When the first conduction module 130 is turned on, the connected first power supply voltage VCC will charge the energy storage module 140.

[0050] In some implementations of the electronic detonator circuit, the control module 110 includes a timer. When the control module 110 receives the detonation signal, it controls the timer to start timing. When the timing time reaches a preset time, it sends a second conduction signal to the second conduction module 160 to conduct the second conduction module 160.

[0051] Specifically, because demolition requires detonation at multiple locations, such as large buildings, precise calculations are needed to control the direction of collapse. This involves determining the location, sequence, and pre-set time between each detonation point. Therefore, every detonation point is crucial. An error at any point could lead to the failure of the entire demolition mission or even cause the building to collapse in a direction contrary to expectations, resulting in a serious safety accident.

[0052] Therefore, the control module 110 in this solution includes a timer, and the second conducting module 160 controlled by the control module 110 will only be turned on when the preset time is reached.

[0053] The timer includes a crystal oscillator, which can optionally provide a clock source for a 32-bit low-power microcontroller and provide precise clock timing for the delay of the electronic detonator.

[0054] For example, if the current blasting operation requires blasting three locations: location A, location B, and location C, the blasting process involves first blasting location A, then starting blasting location C three seconds after location A is blasted, and finally blasting location B five seconds after location C is blasted, thus completing the blasting task. Of course, the 3rd and 5th seconds mentioned above are preset times; the 3rd second is the preset time for blasting between locations A and C, and the 5th second is the preset time for blasting between locations C and B. The preset times in this embodiment can also be other times, and are not limited here.

[0055] In some implementations of electronic detonator circuits, such as Figure 2 As shown, the first conduction module 130 includes: a first MOSFET Q1, a transistor V, and a first resistor R1; the gate of the first MOSFET Q1 is connected to one end of the first resistor R1, the other end of the first resistor R1 is connected to the source of the first MOSFET Q1, and the source of the first MOSFET Q1 is configured to be connected to the first power supply voltage VCC; the drain of the first MOSFET Q1 is connected to the energy storage module 140 and the detonation module 150 respectively; the gate of the first MOSFET Q1 is also connected to the collector of the transistor V, the emitter of the transistor V is grounded, and the base of the transistor V is connected to the control module 110.

[0056] Specifically, the first power supply voltage VCC is applied to the source of the first MOSFET Q1 and reaches the gate of the first MOSFET Q1 through the first resistor R1. To protect the gate from excessive voltage, the first resistor R1 is connected in series for current shunting and protection. When the base of transistor V receives a high-level signal from the control module 110, transistor V conducts. At this moment, it momentarily pulls down the gate voltage of the first MOSFET Q1, creating a voltage difference between the gate and source of the first MOSFET Q1, thus turning on the first MOSFET Q1. The first MOSFET Q1 is a P-type MOSFET, because a P-type MOSFET only conducts when the source voltage is higher than the gate voltage by a certain amount, and the gate input is a low level.

[0057] In some implementations of electronic detonator circuits, such as Figure 2 As shown, the first conducting module 130 also includes: a second resistor R2, a third resistor R3 and a first capacitor C1; one end of the second resistor R2 is connected to the base of the transistor V, the other end of the second resistor R2 is grounded, and the third resistor R3 is connected in series between the base of the transistor V and the control module 110.

[0058] Specifically, since the current that transistor V can withstand in this embodiment is not large, in order to protect transistor V from breakdown, a third resistor R3 needs to be connected in series with the base of transistor V for current limiting. At the same time, considering the influence of the messy level at the base, in order to improve the conduction stability of transistor V, a second resistor R2 is also connected at the base of transistor V to pull down the electrical signal connected to the base.

[0059] In some implementations of electronic detonator circuits, such as Figure 2 As shown, the energy storage module 140 includes a second capacitor C2, a third capacitor C3, a fourth capacitor C4, and a fifth capacitor C5; one end of the second capacitor C2, the third capacitor C3, the fourth capacitor C4, and the fifth capacitor C5 are connected in parallel and respectively connected to the first conducting module 130 and the detonation module 150, and the other end of the second capacitor C2, the third capacitor C3, the fourth capacitor C4, and the fifth capacitor C5 are respectively grounded.

[0060] Specifically, during the blasting process, if the power input line is disconnected due to the blasting of other blasting points or other factors, and the first power supply voltage VCC is not connected, the energy storage module 140 will transmit the voltage in reverse to the voltage regulator module 120 through the first conduction module 130 to supply power to the control module.

[0061] It should be noted that there is a parasitic diode in the P-type MOSFET in the first conducting module 130. The reason why the energy storage module 140 can charge the voltage regulator module 120 through the unconducted first MOSFET Q1 is precisely because it uses this parasitic diode to transmit the electrical signal to the voltage regulator module 120.

[0062] Alternatively, any number of other capacitors can be connected in parallel or in a mixed manner; there are no restrictions here.

[0063] In some implementations of electronic detonator circuits, such as Figure 2 As shown, the second conduction module 160 includes a second MOSFET Q2 and a fourth resistor R4; the gate of the second MOSFET Q2 is connected to one end of the fourth resistor R4 and the control module 110, the other end of the fourth resistor R4 is grounded, the source of the second MOSFET Q2 is grounded, and the drain of the second MOSFET Q2 is connected to the detonation module 150.

[0064] Specifically, when the control module 110 transmits a high level to the gate of the second MOSFET Q2, the second MOSFET Q2 turns on, thereby transmitting a low level to the detonation module 150. When a differential voltage is generated across the detonation module 150, a detonation operation is performed. Similarly, considering the influence of gate scrambled levels, to improve the stability of the second MOSFET Q2's conduction, a fourth resistor R4 is connected at the gate of the second MOSFET Q2 to pull down the gate input level. The second MOSFET Q2 is an N-type MOSFET.

[0065] In some implementations of electronic detonator circuits, such as Figure 2 As shown, the detonation module 150 includes a bridge wire F, one end of which is connected to the energy storage module 140 and the first conduction module 130, and the other end of which is connected to the second conduction module 160.

[0066] Specifically, when one end of the bridge wire F is connected to a high level and the other end is connected to a low level, a voltage difference is generated across the two ends of the bridge wire F, causing the bridge wire F to conduct and ignite, thus igniting the externally connected gunpowder for explosion.

[0067] Alternatively, the detonation module 150 can be a bridge wire F or other ignition resistors R or other components that can ignite externally placed gunpowder; there are no restrictions here.

[0068] In some implementations of electronic detonator circuits, such as Figure 4As shown, the voltage regulator module 120 includes a voltage regulator chip 121, a sixth capacitor C6, a seventh capacitor C7, and a fifth resistor R5. The voltage regulator chip 121 includes a first pin, a second pin, a third pin, and a fourth pin. The first pin is connected to one end of the sixth capacitor C6 and the other end of the sixth capacitor C6 in the control module 110, respectively, and is grounded. The second pin is grounded. The third pin is connected to one end of the fifth resistor R5 and one end of the seventh capacitor C7, and is also configured to be connected to the first power supply voltage VCC. The other end of the fifth resistor R5 is connected to the fourth pin, and the other end of the seventh capacitor C7 is grounded.

[0069] Specifically, the sixth capacitor C6 serves as a biasing element for decoupling. The seventh capacitor C7 stores energy; when the external first power supply voltage VCC is disconnected, it discharges to power the voltage regulator chip 121 and the control module 110, providing a delayed detonation time after power failure. Since the fourth pin of the voltage regulator chip 121 is the enable pin, a fifth resistor R5 is needed in series for current limiting to protect the fourth pin from burning out.

[0070] In addition, the types of voltage regulator chips 121 include linear voltage regulator chips, switching voltage regulator chips, low dropout voltage regulator chips (LDO) and bipolar voltage regulator chips.

[0071] Linear voltage regulators use amplifiers, regulators, and other components to adjust the input voltage to a stable output voltage. The feedback circuit plays a crucial role, comparing the output voltage with a reference voltage and controlling the amplifier's gain to maintain a constant output voltage. Linear regulators offer high output voltage accuracy, but their efficiency is relatively low due to the significant heat generated by their regulating components, making them suitable for low-power and low-noise applications. Switching voltage regulators use switching transistors to control the switching, converting the input voltage into a high-frequency pulse signal, which is then filtered to output a stable voltage. The on-time and off-time of the switching transistor change according to the feedback circuit, thus controlling the stability of the output voltage. Switching regulators offer high efficiency, but require components such as filter capacitors, and their output voltage accuracy is lower than that of linear regulators. Low-dropout (LDO) voltage regulators can achieve voltage regulation when the input voltage is lower than the output voltage by controlling the on / off state of the power transistor. Internally, an error amplifier, regulator, and power transistors control the stability of the output voltage. LDOs can operate normally under low input voltages, but the input voltage must not fall below a certain threshold. Bipolar voltage regulator chips can regulate the output voltage of both positive and negative power supplies, making them suitable for circuits and devices requiring dual power supplies. Their working principle is similar to that of linear voltage regulator chips, but they require separate regulation of the output voltages of both the positive and negative power supplies, thus necessitating multiple feedback circuits and regulators.

[0072] Preferably, the voltage regulator chip 121 in the voltage regulator module 120 of this application is a low dropout voltage regulator chip (LDO), which can effectively operate normally under low input voltage and is suitable for blasting scenarios.

[0073] This application provides an electronic detonator circuit, which includes: a control module 110, a voltage regulator module 120, a first conduction module 130, an energy storage module 140, a detonation module 150, and a second conduction module 160. The voltage regulator module 120 and the first conduction module 130 are connected, and both connection terminals are configured to be connected to a first power supply voltage VCC. The voltage regulator module 120 transmits the first power supply voltage VCC to the control module 110 after adjustment. The control module 110 controls the conduction and disconnection of the first conduction module 130 and the second conduction module 160, respectively. When the first conduction module 130 is on, it transmits the input first power supply voltage VCC to the energy storage module 140 and simultaneously to the detonation module 150. The energy storage module 140 is also connected to the detonation module 150. When the external power supply voltage is disconnected, the circuit of this application is powered by the energy storage module 140, the voltage regulator module 120 and the detonation module 150. The voltage regulator module 120 powers the control module 110, enabling the control module 110 to maintain control for a delay, so as to complete the blasting task on time. This solution can enhance the reliability and stability of the detonator circuit, and also improve the safety of the workers during operation.
