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. Embodiment 1:
[0020] See also Figure 1-Figure 2As shown, the present invention is a high-voltage electronic detonator detonation control module, including a power supply module, a detonation module, a detonation control module and a blasting charge head module; A power supply module is used to connect the detonation module and the detonation control module. The power supply module receives the power supply instruction of the detonation module and generates the high-voltage power input required by the detonation control module. Among them, the power supply module is an 80V high-voltage power supply; The detonation module is used to connect the power supply module and the detonation control module. The detonation module sends a power supply instruction to the power supply module to realize the power supply to the detonation control module. The detonation module sends a control instruction to the detonation control module to complete the sending of electrical signals to the blasting charge head. The detonation control module is used to receive the high-voltage power supply from the power supply module and to receive the control command for detonation from the detonation module. After receiving the detonation control command signal, the detonation control module sends an electrical signal to the blasting charge head module; The blasting charge head module is used to receive the electrical signal from the detonation control module, causing the blasting charge head to explode. Embodiment 2:
[0021] Based on Example 1, the detonation stability of the high-voltage electronic detonator detonation control module is monitored; Specific: For the power supply module, the actual power supply response speed of the power supply module is obtained after the power supply module receives the power supply instruction from the detonation module to the detonation control module; The actual power supply response speed is the response time after the power supply module receives the power supply instruction; The actual power supply response speed of the power supply module and the preset power supply response speed of the power supply module are calculated and the absolute value is taken to obtain the power supply response deviation speed of the power supply module; Calculate the ratio of the power supply response deviation speed of the power supply module to the preset power supply response speed of the power supply module to obtain the power supply response speed deviation ratio of the power supply module; Obtaining the power supply duration of the power supply module after receiving the power supply instruction from the detonation module to the detonation control module; The power supply duration is divided into a number of power supply periods, the power supply voltage at the middle moment of each power supply period is obtained, and the power supply voltages of all power supply periods are integrated to obtain a power supply voltage group; The power supply voltage group is processed according to the variance calculation formula to obtain the voltage variance value of the power supply module; Calculate the difference between the maximum voltage value and the minimum voltage value in the power supply voltage group to obtain the power supply voltage deviation; The power supply voltage deviation is calculated by ratio with the standard value of the power supply voltage to obtain the voltage deviation ratio of the power supply module; The voltage variance value of the power supply module is multiplied by the voltage deviation ratio of the power supply module to obtain the voltage fluctuation value of the power supply module; For the detonation control module, obtaining the actual detonation response speed of the detonation control module after the detonation control module receives the detonation start instruction from the detonation module to the detonation control module; The actual response speed of detonation is the response time after the detonation control module receives the detonation start command; The actual detonation response speed of the detonation control module and the preset detonation response speed of the detonation control module are calculated and the absolute value is taken to obtain the detonation response deviation speed of the detonation control module; Calculate the ratio of the detonation response deviation speed of the detonation control module to the detonation preset response speed of the detonation control module to obtain the detonation response speed deviation ratio of the detonation control module; For the blasting charge head module, the electrical signal received by the blasting charge head module from the detonation control module is monitored; An oscilloscope adapted to the electrical signal transmitted by the detonation control module is used to monitor the electrical signal to obtain a display waveform of the electrical signal; Among them, the oscilloscope has sufficient bandwidth, sampling rate and resolution to accurately capture and display the signal waveform; Acquire the maximum amplitude of the signal and the minimum amplitude of the signal in the displayed waveform of the electrical signal; The maximum amplitude of the signal and the minimum amplitude of the signal are calculated by difference, and the obtained amplitude difference is calculated by ratio with the average amplitude of the signal to obtain the signal stability of the blasting charge head module; The average amplitude of the signal can be obtained by direct measurement or indirect calculation.
[0022] For example, direct measurement method: using an oscilloscope: Connect the input of the oscilloscope to the signal source to be measured; Adjust the time base and voltage axis scale of the oscilloscope to clearly display the signal waveform; Trigger the oscilloscope to capture the signal stably; Read multiple amplitude values of the signal on the oscilloscope and calculate the average of these values to obtain the average amplitude of the signal.
[0023] The power supply response speed deviation ratio of the power supply module is recorded as Gx; The detonation response speed deviation ratio of the detonation control module is recorded as Bx; The stability of the signal of the blasting charge module is recorded as Yw; By formula The detonation fluctuation value Bi of the high-voltage electronic detonator detonation control module is calculated, where Gf is the voltage fluctuation value of the power supply module; The larger the detonation variation value Bi of the high-voltage electronic detonator detonation control module is, the worse the operation stability of the high-voltage electronic detonator detonation control module is. If the detonation variation value of the high-voltage electronic detonator detonation control module exceeds the preset range, it means that the control stability of the high-voltage electronic detonator detonation control module is poor and the safety is low, thereby completing the effective monitoring of the stability of the high-voltage electronic detonator detonation control module; It can be seen from the above formula for obtaining the detonation abnormality value of the high-voltage electronic detonator detonation control module that the larger the power supply response speed deviation Gx of the power supply module, the larger the deviation between the execution action of the power supply module after receiving the power supply instruction of the detonation module and the preset execution action, and the larger the detonation abnormality value of the high-voltage electronic detonator detonation control module obtained, the more unstable the detonation of the high-voltage electronic detonator detonation control module; The larger the detonation response speed deviation ratio Bx of the detonation control module is, the larger the deviation between the execution action of the detonation control module after receiving the detonation start instruction of the detonation module and the preset execution action is, and the larger the detonation abnormal value of the high-voltage electronic detonator detonation control module is, and the more unstable the detonation of the high-voltage electronic detonator detonation control module is; The greater the signal stability Yw of the blasting charge head module, the higher the stability of the electrical signal transmitted by the detonation control module to the blasting charge head module, the smaller the detonation variation value of the high-voltage electronic detonator detonation control module, and the more stable the detonation of the high-voltage electronic detonator detonation control module; The larger the voltage fluctuation value Gf of the power supply module, the greater the transmission deviation of the power supply voltage after the power supply module receives the power supply instruction from the detonation module, the larger the detonation variation value of the high-voltage electronic detonator detonation control module obtained, and the more unstable the detonation of the high-voltage electronic detonator detonation control module. Embodiment 3:
[0024] like Figure 2 The figure shows the circuit connection schematic diagram of the high-voltage electronic detonator detonation control module, including the module control chip, the rectifier bridge circuit composed of the diodes D1-D4, the protection resistors R1 and R2, the current limiting protection resistors R3 and the voltage limiting Zener tube Z1, the NMOS tube Q1, the voltage stabilizing filter capacitors C1 and C2, the diodes D5 and the Zener tube Z2, the energy storage capacitors C3 and the protection resistors R4, the fuse bridge FUSE, the NMOS tube Q2 and the pull-down resistor R5, and the Schottky diode D6; Specifically: the IN port of the module control chip is connected with the protection resistor R1, the protection resistor R2 and the rectifier bridge circuit; The rectifier bridge circuit is composed of diode D1, diode D2, diode D3 and diode D4; The protection resistor R3 and the voltage-limiting Zener diode Z1 form a circuit for power input and communication input; The MOD port of the module control chip is connected to the gate of the NMOS tube Q1 to form a communication command return loop, and transmits the foul response to the power input and communication input loops; The diode D5 and the voltage-limiting Zener diode Z2 are connected to the energy storage capacitor C3 and the protection resistor R4 to form a charging circuit for the energy storage capacitor C3. At the same time, the voltage-limiting Zener diode Z2 can shield the charging of the energy storage capacitor C3 when the detonation control module communicates; The protection resistor R5 and the gate of the NMOS tube Q2 connected to the START port of the module control chip form an ignition start command execution loop; The FUSE port of the module control chip is connected to the Schottky diode D6 and then to the fuse bridge wire FUSE to form a FUSE detection instruction execution loop; The VDD12 port of the module control chip is connected to the voltage stabilizing filter capacitor C2; The module control chip V18 port is connected to the voltage stabilizing filter capacitor C1; The energy storage capacitor C3, the fuse FUSE, and the NMOS tube Q2 together constitute a discharge circuit of the energy storage capacitor C3; The GND port of the module control chip and the ground terminals of peripheral components are grounded together.
[0025] The rectifier bridge circuit composed of diode D1, diode D2, diode D3 and diode D4 enables the input of IN1 and IN2 to work normally regardless of positive or negative connection, and will not damage the detonation control module; The protection resistors R1 and R2 are current limiting protection resistors connected in series in the bridge circuit, which can effectively protect the bridge. The protection resistor R3 and the voltage-limiting Zener diode Z1 together constitute a circuit protection function, which provides overcurrent protection and overvoltage protection for the module control chip. The high-voltage input power is input into the IN port of the module control chip after voltage and current limiting.
[0026] The gate of the NMOS tube Q1 is connected to the MOD port of the module control chip. When the module control chip receives some instructions at the IN port, it promptly controls the NMOS tube Q1 to be turned on through the MOD port, and transmits the return response to the power input and communication input loops.
[0027] The diode D5, the voltage limiting Zener diode Z2, the energy storage capacitor C3 and the protection resistor R4 together constitute an energy storage capacitor charging circuit. When a high voltage electrical signal is input from the positive input end of the diode D5, it is transmitted to the energy storage capacitor C3 after passing through the voltage limiting Zener diode to realize the charging action of the energy storage capacitor.
[0028] When the energy storage capacitor is fully charged but no discharge is performed to start the ignition command, the point on the energy storage capacitor C3 will be slowly released through the protection resistor R4. The resistor R4 plays a discharging role and together with the energy storage capacitor C3 forms a discharge circuit to eliminate the safety hazard caused by the high-voltage discharge of the energy storage capacitor C3.
[0029] The Schottky diode D6 and the fuse bridge FUSE are connected to the resistor R4 to form a FUSE detection circuit. When the module control chip receives the FUSE detection instruction sent by the front-end detonator, the FUSE port of the module control chip will send out a weak current, which flows through the Schottky diode D6, flows through the FUSE and then to the resistor R4 to be grounded. When the fuse bridge FUSE does not exist or has been blown, the weak current cannot flow out, thereby realizing the FUSE detection instruction of the module control chip.
[0030] Resistor R5, NMOS tube Q2, fuse FUSE and energy storage capacitor C3 together constitute the discharge circuit of the energy storage capacitor. The START port of the module control chip is connected to the gate of the NMOS tube and one end of the resistor R5. After the module control chip is powered on, the START port cannot guarantee to work in a stable state immediately. At this time, resistor R5 can play a pull-down protection role to ensure that the NMOS tube Q2 can be in the off state when the module control chip is not in a stable state.
[0031] When the module control chip receives the start ignition command, STRAT will output a high-level signal to turn on the NMOS tube Q2, and the lower end of the fuse FUSE will be directly grounded. At this time, the fully charged energy storage capacitor C3 instantly releases a high-energy electrical signal through the fuse to the ground, guiding the fuse FUSE to generate an electric spark, triggering the detonator to complete the detonation action.
[0032] Capacitor C1 is connected to the module control chip V18 port to form a voltage stabilizing filter capacitor, so that the output voltage of the module control chip V18 port is stabilized at 1.8V; Capacitor C2 is connected to the module control chip VDD12 port to form a voltage stabilizing filter capacitor, so that the output voltage of the module control chip VDD12 port is stabilized at 12V.
