Consequently, the existing 220V detonators have a limited blasting mode, requiring more complex construction methods and increasing the difficulty of construction. Furthermore, the blasting controller cannot detect the detonation voltage and the safety of the detonation branch before activation.

[0003] Therefore, further improvements and developments are needed for existing technologies. Summary of the Invention

Therefore, the detection feedback unit in the discharge assembly feeds back the detected data to the detection feedback input signal unit, avoiding direct connection between the discharge assembly and the CPU, which would cause interference to the CPU and result in insufficient control sensitivity and accuracy. Thus, it has stronger anti-interference capability.

[0049] To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0050] like Figure 1-17 As shown, the present invention discloses a control assembly for a blasting controller, which includes:

[0051] CPU 1 is used to receive input signals, output control signals, and process data;

[0052] Memory module 2, which is used to store data and is connected to CPU 1;

[0053] The preset mode input signal source unit 3 is used to input a preset demolition mode, and the preset mode input signal source unit 3 is connected to the CPU 1;

[0054] CPU output and control unit 4 is used to output signals and control the discharge circuit to discharge. The CPU output and control unit 4 is connected to the CPU 1.

[0055] The key input signal unit 5 is used for user input signals to the CPU 1, and the key input signal unit 5 is connected to the CPU 1;

[0056] The liquid crystal display unit 6 is used to display the output signal, and the liquid crystal display unit 6 is connected to the CPU 1;

[0057] The download program module 7 is used to input programs to the CPU 1, and the download program module 7 is connected to the CPU 1;

[0058] The system also includes a power supply module 8, which provides power to the CPU 1, memory module 2, preset mode input signal source unit 3, CPU output and control unit 4, download program module 7, and LCD display unit 6.

[0059] With the above structure, the present invention can supply power to the CPU 1 and the CPU output and control unit through the power module 8, and input a preset blasting mode to the CPU 1 through the preset mode input signal source unit 3. Therefore, the present invention can realize the switching of preset modes according to the needs of the blasting scenario. Compared with traditional blasting methods, the present invention has multiple control modes and can freely set the control mode. In addition, the present invention realizes the input and setting of preset modes through the button input signal unit 5, and simultaneously inputs control signals. The present invention realizes intelligent control of the blasting controller through the CPU 1, and can control the discharge unit to discharge according to the set blasting mode, realizing multiple blasting control methods. The CPU 1 can receive and detect in time whether the discharge voltage of the high-voltage capacitor used for discharge has reached the safe detonation voltage condition. If the safe detonation voltage has not been reached, even if the blasting input command is pressed, it will not be executed, thus ensuring the safety of blasting construction. The preset multiple blasting modes can be used in more scenarios, and make blasting construction projects simpler, more convenient, and safer. The LCD display unit 6 can display the output signals, allowing operators to understand the blasting operation. The download program module 7 can erase the existing control instruction program from a computer or USB flash drive, and can also update the control instruction program in the CPU 1. The power supply module 8 provides power to the aforementioned modules or units that require electricity.

[0060] Preferably, it also includes a detection feedback input signal unit 9 for feeding back the detection signal, the detection feedback input signal unit 9 being connected to the CPU 1.

[0061] Because the detection feedback signal input unit is connected to the CPU 1, it is possible to detect whether the high-voltage capacitor in the discharge assembly used for detonating detonators has reached the safe detonation voltage, and whether the battery in the power module 8 is fully charged to meet the requirements for safe discharge.

[0062] Preferably, the detection feedback input signal unit 9 includes multiple detection feedback branches 90, the detection feedback branches 90 are connected to the discharge assembly through input ports, and the output terminals of the detection feedback branches 90 are connected to the CPU 1.

[0063] Preferably, the detection feedback branch 90 has the same circuit as the preset signal input branch 30, but the connection pins to the CPU 1 are different.

[0064] The detection feedback input signal unit 9 is connected to the discharge assembly. Therefore, the detection feedback unit in the discharge assembly feeds back the detected data to the detection feedback input signal unit 9, avoiding direct connection between the discharge assembly and the CPU 1, which could cause interference to the CPU 1 and result in insufficient control sensitivity and accuracy. This provides stronger anti-interference capability. Preferably, the detection feedback input signal unit 9 includes 3 or 6 detection feedback branches 90.

[0065] Preferably, it also includes a crystal oscillator unit 10 for controlling timing accuracy, the crystal oscillator unit 10 being connected to the CPU 1. The crystal oscillator unit 10 is a conventional technology, but by connecting it to the CPU 1, it is possible to control the detonation of the blaster to the microsecond level.

[0066] Preferably, it also includes a reset unit 11 for resetting to zero, the reset unit 11 being connected to the CPU 1.

[0067] 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 erroneous, a zero-reset can be achieved, allowing the CPU 1 to return to the initial state.

[0068] 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.

[0069] Preferably, the preset mode input signal source unit 3 includes multiple preset signal input branches 30. The signal output terminals of the preset signal input branches 30 are connected to the CPU 1, and the preset signal input branches 30 are connected to a multi-position switch via a wiring port P2. 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 5 preset modes, which is also a 5-channel preset signal input branch 30.

[0070] 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, and a first protection resistor 22 for protecting the output signal terminal of the optocoupler; the signal input terminal of the optocoupler 13 is connected in series with the adjusting resistor assembly 21, and the adjusting resistor assembly 21 is connected to the wiring port P2.

[0071] The power module 8 is connected to the output signal terminal of the optocoupler 13 through the first protection resistor 22;

[0072] 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.

[0073] With the above structure, the present invention prevents the output terminal of the optocoupler 13 from short-circuiting through the first 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 30 is connected.

[0074] Preferably, the CPU output and control unit 4 includes a multi-channel output and control branch 40, the signal input terminal of the output and control branch 40 is connected to the signal output terminal of the CPU 1, and the output terminal of the output and control branch 40 is connected to the discharge assembly through the output wiring port 41.

[0075] like Figure 12 and 13 As shown, in this embodiment, the CPU output and control unit 4 includes six output and 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.

[0076] Preferably, the output and 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, a first high-voltage diode 17 for preventing reverse current, and a second high-voltage diode 18.

[0077] 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;

[0078] The output terminal of the optocoupler 13 is connected to the collector of the protection resistor assembly 14 and the transistor 15, respectively.

[0079] 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.

[0080] The relay 16 is connected to the discharge assembly via a switch; the emitter of the transistor 15 is grounded.

[0081] The first high-voltage diode 17 and the second high-voltage diode 18 are respectively connected in parallel with the relay 16.

[0082] Preferably, the power module 8 is connected to the output and control branch 40 via an anti-reverse diode.

[0083] The protection resistor assembly includes a second protection resistor 140 and a third protection resistor 141. The second protection resistor 140 and the third protection resistor 141 are connected in parallel, and the second protection resistor 140 is connected to the positive terminal of the output of the optocoupler 13 through a diode.

[0084] 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.

[0085] 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 CPU output and control unit 4, which outputs signals and controls the discharge circuit to discharge, thus achieving discharge. The CPU output and control unit effectively isolates the discharge circuit from interference with CPU 1's control commands and enables output control. 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.

[0086] 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.
