[0040] Example 1
[0041] An embodiment of the present application provides an electronic detonator initiating device.
[0042] See also Figure 1 , Figure 1 A schematic diagram of the structure of an electronic detonator 600 detonating device provided in an embodiment of the present application is shown, the device comprising: a main control module 300, a first switch module 400, a current limiting module 200, a power supply module 100, a driving module 500 and a plurality of electronic detonators 600; the main control module 300 is electrically connected to the first switch module 400, the current limiting module 200 and the power supply module 100, respectively, and is used to obtain a detected temperature value of the power supply module 100, and if the detected temperature of the power supply module 100 is less than a preset temperature threshold, the first switch module 400 is controlled to be turned on; the current limiting module 200 is electrically connected to the first switch module 400, the current limiting module 200 and the power supply module 100, respectively, and is used to obtain a detected temperature value of the power supply module 100, and if the detected temperature of the power supply module 100 is less than a preset temperature threshold, the first switch module 400 is controlled to be turned on; 00, respectively electrically connected to the power supply module 100, the main control module 300 and the first switch module 400, for reducing the power supply current of the power supply module 100; the driving module 500 is also respectively electrically connected to the main control module 300, each of the electronic detonators 600 and the first switch module 400, for obtaining an initial charging voltage from the power supply module 100 through the first switch module 400 if the power supply current is less than a preset current threshold, and obtaining a target charging voltage according to the initial charging voltage, and charging each of the electronic detonators 600 according to the target charging voltage.
[0043] It should be noted that by adding the judgment of the real-time temperature of the power supply module 100 and selecting the corresponding switch module to conduct according to the real-time temperature, the charging current of the detonator is reduced in the low temperature extreme environment, so that the electronic detonator will not shut down and restart when the detonator is charging, thereby ensuring the continuity and safety of the charging and detonation operation. Among them, the electronic detonator 600 includes a plurality of electronic detonators.
[0044] In one embodiment, see Figure 2The device also includes: a second switch module 700; the main control module 300 is also electrically connected to the second switch module 700, and is used to control the first switch module 400 to be turned on and the second switch module 700 to be turned off if the detected temperature of the power supply module 100 is less than a preset temperature threshold, and electrically connect the power supply module 100 and the driving module 500 through the first switch module 400.
[0045] In this embodiment, the main control module 300 is a micro control unit 301, which is powered by the power supply module 100. The micro control unit 301 sends a temperature detection signal to the power supply module 100. After obtaining the temperature value, the temperature value is judged. If the temperature value is less than the preset temperature threshold, the first switch control end of the micro control unit 301 becomes a high level, so that the first switch module 400 is turned on, and the second switch control end becomes a low level, so that the second switch module 700 is turned off. At this time, the current value of the power supply module 100 reduces the charging current after passing through the current limiting module 200. When the charging current is reduced to the preset current threshold, the driving module 500 obtains the power supply voltage of the power supply module 100, and the control unit 301 controls the target charging voltage to charge each electronic detonator 600.
[0046] In one embodiment, the main control module 300 also includes: a control unit 301; the control unit 301 is electrically connected to the second switch module 700, and is also used to control the second switch module 700 to be turned on and the first switch module 400 to be turned off if the detected temperature of the power supply module 100 is greater than the preset temperature threshold, and the power supply module 100 and the driving module 500 are electrically connected through the second switch module 700.
[0047] It should be noted that after the temperature value is obtained, the temperature value is judged. If the temperature value is greater than the preset temperature threshold, the first switch control terminal of the micro control unit 301 becomes a low level, so that the first switch module 400 is turned off, and the second switch control terminal becomes a high level, so that the second switch module 700 is turned on. At this time, the driving module 500 directly obtains the power supply voltage of the power supply module 100, and the micro control unit 301 controls the charging of each electronic detonator 600. Among them, the preset temperature threshold can be set according to actual conditions.
[0048] For example, when the microcontroller unit 301 detects that the battery temperature is above -20 degrees, the second switch control terminal of the microcontroller unit 301 is at a high level, turning on the second switch module 700, and the first switch control terminal is at a low level, turning off the first switch module 400. At this time, the battery 8.7V is turned on through the second switch module 700 to supply power to the drive module 500, and the microcontroller unit 301 controls each serial port to charge each electronic detonator 600 connected to the bus.
[0049] Optionally, the control unit 301 is also electrically connected to the driving module 500, the first switch module 400 and the power supply module 100. Optionally, the main control module 300 further includes: a reference unit 302; the reference unit 302 is electrically connected to the control unit 301, the power supply module 100, the second switch module 700 and the current limiting module 200, respectively, and is used to perform voltage reduction processing on the acquired voltage value of the power supply module 100 until a target voltage is obtained, and the control unit 301 is powered according to the target voltage.
[0050] In this embodiment, when the battery voltage of 8.7V is reduced to 3.3V through the reference unit 302, 3.3V is used as the power supply voltage to power the micro control unit 301. The battery temperature measurement unit 101 receives the temperature detection signal of the micro control unit 301. The micro control unit 301 detects that the battery temperature is below -20 degrees. The first switch control terminal of the micro control unit 301 outputs a high level to turn on the first switch module 400. The second switch control terminal of the micro control unit 301 is a low level to turn off the second switch module 700. At this time, the battery voltage of 8.7V passes through the current limiting module 200, and the charging current is reduced by the current limiting module 200. At this time, the battery voltage of 8.7V passes through the second switch module 700 to power the driving module 500. The micro control unit 301 controls each serial port to charge each electronic detonator 600 connected to the bus.
[0051] It should be understood that the reference unit is an LDO (Low Dropout Regulator), which converts a higher input voltage into a stable output voltage.
[0052] In one embodiment, if Figure 3 As shown, the driving module 500 includes: a boost unit 501 and a charging unit 502; the boost unit 501 is electrically connected to the main control module 300, the first switch module 400 and the second switch module 700, respectively, and is used to perform a boost process on the initial charging voltage until the target charging voltage is obtained. The charging unit 502 is electrically connected to each of the electronic detonators 600 and the boost unit 501, respectively, and is used to charge each of the electronic detonators 600 according to the target charging voltage obtained by the boost unit 501.
[0053] It should be noted that the boost unit 501 is a DCDC direct current conversion circuit. When the switch is closed, the input voltage is applied to the inductor. When the switch is opened, the inductor is magnetized and energy is released through the diode at the output end to achieve the boost function, thereby obtaining the target charging voltage and charging each of the electronic detonators 600 through the charging unit 502.
[0054] In one embodiment, the power supply module 100 includes: a temperature measuring unit 101 and a power supply unit 102; the temperature measuring unit 101 is electrically connected to the control unit 301 and the power supply unit 102, respectively, for obtaining the detected temperature value of the power supply unit 102 and sending the detected temperature value to the main control module 300; the power supply unit 102 is also electrically connected to the current limiting module 200 and the reference unit 302, respectively.
[0055] It should be noted that the temperature of the power supply unit 102 is measured by adding a thermistor, and a resistor with a fixed resistance is connected in series to form a voltage divider circuit. By measuring the voltage value at both ends of the thermistor, its resistance value can be calculated, and then the temperature value can be obtained.
[0056] In one embodiment, the current limiting module 200 includes: a current limiting resistor, which is electrically connected to the power supply module 100, the first switch module 400 and the main control module 300. Optionally, the current limiting resistor is an adjustable resistor.
[0057] It should be noted that, in other implementations, the current limiting purpose can be achieved by a current limiting IC.
[0058] An electronic detonator detonating device provided in an embodiment of the present application includes: a main control module electrically connected to a first switch module, a current limiting module and a power supply module, respectively, for obtaining a detected temperature value of the power supply module, and controlling the first switch module to be turned on if the detected temperature of the power supply module is less than a preset temperature threshold; a current limiting module electrically connected to the power supply module, the main control module and the first switch module, respectively, for reducing the power supply current of the power supply module; a driving module, also electrically connected to the main control module, each electronic detonator and the first switch module, respectively, for obtaining an initial charging voltage from the power supply module through the first switch module if the power supply current is less than a preset current threshold, and obtaining a target charging voltage according to the initial charging voltage, and charging each electronic detonator according to the target charging voltage. This solution can ensure system stability in low temperature extreme environments, avoid system shutdown or restart problems caused by too low temperature, and thus ensure the continuity and safety of charging and detonating operations.
