[0060] The 220V detonator assembly circuit further includes a crystal oscillator unit 10 for controlling timing accuracy, and the crystal oscillator unit 10 is connected to the CPU 1. Preferably, the crystal oscillator unit 10 is a conventional technology, but by connecting it to the CPU 1, the detonation of the detonator can be controlled at the microsecond level, making the detonator control more precise.

[0061] Preferably, it also includes a reset unit 11 for resetting to zero, the reset unit 11 being connected to the CPU 1.

[0062] With the above structure, the present invention can reset the control assembly through the reset unit 11. When the output control commands are disordered or incorrect, a zero reset can be achieved, allowing the CPU 1 to return to the initial state and ensuring the control safety of the detonator.

[0063] Preferably, it also includes a filtering unit 12 for filtering, which is connected to the CPU 1; therefore, the filtering unit 12 can prevent the power supply module 8 from interfering with the current of the CPU 1, making the control of the CPU 1 more precise.

Each preset signal input branch 30 represents a preset mode, such as... Figure 10 As shown, the preset mode input unit in this embodiment has a preset mode, which is a preset signal input branch 30.

[0065] Preferably, the preset signal input branch 30 includes an indicator light 20 for displaying the on / off state of the preset mode, an optocoupler 13, an adjusting resistor assembly 21 for adjusting the power supply voltage of the optocoupler 13, and a second protection resistor 22 for protecting the output signal terminal of the optocoupler 13.

[0066] The signal input terminal of the optocoupler 13 is connected in series with the regulating resistor assembly 21, and the regulating resistor assembly 21 is connected to the wiring port P2.

[0067] The power module 8 is connected to the output signal terminal of the optocoupler 13 through the second protection resistor 22;

[0068] The adjustable resistor assembly 21 includes a first adjustable resistor 210 and a second adjustable resistor 211; the first adjustable resistor 210 is connected in series with the indicator light 20 and then in parallel with the second adjustable resistor 211.

[0069] With the above structure, the present invention prevents the output terminal of the optocoupler 13 from short-circuiting through the second protection resistor 22, and adjusts the voltage and current of the preset mode through the first adjustment resistor 210 and the second adjustment resistor 211. The indicator light 20 is used to indicate whether the preset signal input branch is connected.

[0070] In the 220V detonator assembly circuit, the signal input terminal of the output discharge control branch 40 is connected to the signal output terminal of the CPU 1, and the output terminal of the output and transmission control branch is connected to the discharge wire through the output wiring port.

[0071] like Figure 11 and 12As shown, in this embodiment, the output discharge control unit 4 includes six output discharge control branches 40, thus enabling the control of six detonators for blasting. Compared to existing single-channel detonators, it can meet more detonation scenarios, resulting in more precise blasting and higher blasting efficiency.

[0072] Preferably, the output discharge control branch 40 includes an optocoupler 13, a protection resistor assembly 14 for protecting the optocoupler, a transistor 15 for signal switching, a relay 16, and a first high-voltage diode 17 for preventing reverse current.

[0073] The signal input terminal of the optocoupler 13 is connected to the signal output terminal of the CPU 1, and is connected to the power module 8 through a current-limiting resistor 19;

[0074] The output terminal of the optocoupler 13 is connected to the collector of the protection resistor assembly 14 and the transistor 15, respectively.

[0075] One end of the relay 16 is connected to the power module 8, and the other end of the relay 16 is connected to the base of the transistor 15.

[0078] Preferably, the protection resistor assembly 14 includes a third protection resistor 140 and a fourth protection resistor 141, which are connected in parallel and then connected to the output terminal of the optocoupler 13.

[0079] With the above structure, the present invention can protect the optocoupler 13 by using the protection resistor component 14 to prevent the optocoupler 13 of the power module 8 from being impacted, and can control the switching of the relay 16 by using the transistor 15, thereby making the controller's control effect better, and ensuring that the signal output by the CPU 1 is not interfered with by the discharge assembly, and has higher accuracy.

[0080] This invention utilizes CPU 1 to receive and output control signals. The preset mode input signal source unit 3 inputs a preset blasting mode and transmits it to CPU 1. CPU 1 then outputs control commands to the output discharge control unit 4, which outputs signals and controls the discharge circuit to discharge, thus achieving discharge. The output discharge control unit 4 effectively isolates the discharge circuit from interference with the CPU 1's control commands and enables output control transmission. The liquid crystal display unit 6 displays the output signals, allowing operators to understand the output control signals and control commands. Therefore, this invention enables the selection and preset of control modes and can output control signals as needed, achieving precise control. The button input signal unit 5 allows manual input of preset modes and control commands. The download program module 7 updates and modifies the control program within CPU 1, making it suitable for different blasting control scenarios. Furthermore, the output discharge control unit 4 of the present invention uses a 220V power supply as the power supply for the detonator, so the power supply is simple. Therefore, the detonator can boost the power of the lithium battery and deliver it to the high-voltage capacitor without the need for a boost circuit and a high-voltage capacitor. The high-voltage capacitor is then connected to the discharge assembly for discharge. Therefore, the overall circuit is simpler, and the power supply for blasting is convenient, as long as the 220V voltage is connected.

[0081] The above are merely preferred embodiments of the present invention, and should not be construed as limiting the scope of the present invention. It should be noted that for those skilled in the art, any modifications or equivalent substitutions to the technical solutions of the present invention without creative effort do not depart from the protection scope of the technical solutions of the present invention.
