Description

Technical Field

[0001] The present invention relates to the technical field of electronic detonators, and in particular to a method and system for wireless through-the-ground communication to prevent static electricity interference. Background Art

[0002] In the field of modern blasting engineering, wireless ground-penetrating communication technology has been widely used in underground mining, tunnel excavation and other operations due to its advantages of no need for wiring and easy installation. Wireless electronic detonators, as the key executive components of this technology, can accurately control the detonation time and sequence, significantly improving the blasting effect and safety.

[0003] However, the actual working environment is often extremely complex, with a large number of static interference sources, such as equipment friction, air ionization, etc. These static interferences can easily have a serious impact on the detonation signal transmitted by the wireless communication module, causing signal distortion, bit errors, or even loss. Once static interference occurs, the wireless electronic detonator will stop working, resulting in explosion refusal or premature explosion.

[0004] Based on this, there is an urgent need for a wireless through-the-ground communication anti-static interference method and system, which can improve the anti-static interference capability of wireless electronic detonators, ensure the accurate reception and execution of detonation signals by wireless electronic detonators, and thus avoid the problem of blasting failure caused by electrostatic interference. Summary of the invention

[0005] One of the purposes of the present invention is to provide a wireless through-the-ground communication anti-static interference method and system, which can improve the anti-static interference capability of wireless electronic detonators, ensure the accurate reception and execution of detonation signals by wireless electronic detonators, and thus avoid the problem of blasting failure caused by static interference.

[0006] In order to achieve the above-mentioned object, a wireless through-the-ground communication anti-static interference system is provided, including an anti-static interference wireless electronic detonator, wherein the anti-static interference wireless electronic detonator includes a wireless communication module, a first anti-static interference module, a second controller, and a basic electronic detonator;

[0007] The output end of the wireless communication module is connected to the input end of the first anti-static interference module, the output end of the first anti-static interference module is connected to the input end of the second controller, and the output end of the second controller is connected to the input end of the basic electronic detonator;

[0008] The second controller is used to receive the detonation signal processed by the first anti-static interference module from the wireless communication module; the second controller is used to control the detonation of the basic electronic detonator according to the received detonation signal.

[0009] Technical principle and effect of this solution: In this solution, the wireless communication module is responsible for receiving the external detonation signal and transmitting it to the first anti-static interference module. In actual application scenarios, the signal transmission process is susceptible to static interference. The first anti-static interference module removes the static interference mixed in the detonation signal during the transmission process through its own circuit design, ensuring that the signal transmitted to the second controller is pure and accurate.

[0010] After receiving the detonation signal processed by the first anti-static interference module, the second controller analyzes, identifies and processes the signal. According to the preset detonation logic and conditions, it is determined whether the detonation requirements are met. If they are met, the corresponding control instructions are sent to the basic electronic detonator to trigger the detonation mechanism of the basic electronic detonator to achieve accurate detonation of the detonator.

[0011] Through the effective processing of electrostatic interference by the first anti-static interference module, the probability of signal error or loss caused by electrostatic interference is reduced, so that the second controller can receive accurate detonation signals, thereby improving the reliability of basic electronic detonator detonation and reducing the occurrence of abnormal situations such as explosion refusal. In complex environments with electrostatic interference (such as excavation face blasting and other scenarios), the system can effectively resist electrostatic interference, ensure the normal operation of wireless through-the-ground communication and the reliable detonation of detonators, and enhance the adaptability and stability of the system in different environments. That is, it can improve the anti-static interference capability of wireless electronic detonators, ensure the accurate reception and execution of detonation signals by wireless electronic detonators, and avoid the problem of blasting failure caused by electrostatic interference.

[0012] Further, the first anti-static interference module includes a first controller, a first current limiting resistor, a second current limiting resistor, a first diode, a second diode, a first protection capacitor and a second protection capacitor;

[0013] The input end of the first controller is connected to the wireless communication module, the anode of the first output end of the first controller is connected to the anode of the second input end of the second controller, and the cathode of the first output end of the first controller is connected to the cathode of the second input end of the second controller;

[0014] The first current limiting resistor is connected in series to the anode of the first output terminal; the second current limiting resistor is connected in series to the cathode of the first output terminal;

[0015] One end of the first diode is arranged on the line between the first current limiting resistor and the second controller, and the other end of the first diode is grounded; one end of the second diode is arranged on the line between the second current limiting resistor and the second controller, and the other end of the second diode is grounded;

[0016] One end of the first protection capacitor is arranged on the line between the first current limiting resistor and the second controller, and the other end of the first protection capacitor is grounded; one end of the second protection capacitor is arranged on the line between the second current limiting resistor and the second controller, and the other end of the second protection capacitor is grounded.

[0017] Beneficial effect: In this solution, the first current limiting resistor and the second current limiting resistor are respectively connected in series to the anode and cathode of the line connecting the first controller and the second controller. When an electrostatic high-voltage pulse occurs, the resistor plays a current limiting role, reducing the current intensity of the electrostatic high-voltage pulse, thereby reducing the risk of damage to the input end of the second controller. For example, if the electrostatic high-voltage pulse instantly generates a large current, the current limiting resistor can limit the current to the range that the second controller can withstand, avoiding faults such as chip burning due to excessive current.

[0018] The first diode and the second diode play a key role in discharging static electricity in the circuit. During normal operation, the diode is in a high-resistance state and does not affect the normal signal transmission of the circuit; once high-voltage static electricity is generated, the diode quickly turns on and is in a low-resistance state, discharging the static electricity energy directly to the ground. For example, when static electricity causes the line voltage to suddenly increase, the first diode and the second diode respectively conduct the static electricity on the anode and cathode lines to the ground, protecting the second controller connected thereto and preventing static electricity from breaking down the electronic components of the second controller.

[0019] The first protection capacitor and the second protection capacitor can effectively filter the high-frequency radiation generated by static electricity. When the first controller generates static electricity, it will be accompanied by high-frequency radiation, which may interfere with the normal operation of other circuit components, especially affect signal transmission. By utilizing its capacitance characteristics, the high-frequency radiation is bypassed and filtered, so that the high-frequency interference signal is grounded through the capacitor, reducing the electromagnetic interference to the second controller and the entire communication link, and ensuring the stability and accuracy of the detonation signal transmission.

[0020] The first anti-static interference module effectively suppresses the electrostatic interference in the detonation signal transmitted from the wireless communication module, ensuring that the detonation signal received by the second controller is complete and accurate. This is crucial for the precise detonation control of basic electronic detonators, avoiding problems such as detonation failure, premature detonation or confusion in detonation sequence caused by signal errors, and improving the reliability and safety of the entire wireless through-the-ground communication anti-static interference system.

[0021] Furthermore, a second anti-static interference module is provided between the second controller and the basic electronic detonator.

[0022] Beneficial effect: In this solution, the first anti-static interference module first purifies the signal transmitted from the wireless communication module to remove the static interference noise, so that the second controller can receive an accurate detonation signal. The second anti-static interference module further processes the signal output by the second controller, and again filters out the static interference that may be mixed in, ensuring that the detonation signal received by the basic electronic detonator is accurate. This dual anti-static interference mechanism greatly improves the accuracy of the detonation signal, effectively avoids problems such as refusal to explode and premature explosion caused by signal errors, and ensures that the blasting operation proceeds smoothly according to the predetermined plan.

[0023] Further, the second anti-static interference module includes a power-on reset module, a reset filter module, an oscillator, and an ignition control module;

[0024] One end of the power-on reset module is connected to the anode of the second input terminal of the second controller, the other end of the power-on reset module is connected to one end of the reset filter module, the other end of the reset filter module is connected to one end of the oscillator, and the other end of the oscillator is connected to the anode of the second input terminal of the second controller;

[0025] The input end of the ignition control module is connected to the output end of the second controller, and the output end of the ignition control module is connected to the input end of the basic electronic detonator.

[0026] Beneficial effects: In this scheme, the power-on reset module is connected to the anode of the second input terminal of the second controller. When the system is powered on, it can provide an initial reset signal for the entire module to ensure that the system starts working from a certain initial state. This can avoid the system from entering an uncertain state when powered on due to factors such as electrostatic interference, and ensure the stability and consistency of system startup. The reset filter module can filter the signal output by the power-on reset module, eliminate these high-frequency noises, and prevent the wrong reset signal from being transmitted to the oscillator and subsequent circuits. The oscillator is connected to the anode of the second input terminal of the second controller and receives the signal after filtering. It can generate a stable clock signal and provide an accurate time reference for the entire system. In blasting operations, accurate delay time control is crucial. The oscillator can accurately control the detonation time of the basic electronic detonator according to preset parameters to ensure that the blasting operation is carried out according to the predetermined plan. That is, there is still residual electrostatic energy entering the second controller. Through reset filtering and filtering high-frequency electrostatic interference noise, the wrong reset signal input is prevented, so that the electronic control module cannot work normally, thereby causing explosion rejection.

[0027] Furthermore, the anti-static interference wireless electronic detonator also includes a dial switch electrically connected to the first controller.

[0028] Beneficial effects: The DIP switch allows operators to personalize the detonator according to specific blasting requirements. During the production, installation and maintenance of detonators, the DIP switch provides technicians with an intuitive and convenient debugging method.

[0029] Furthermore, the wireless communication module includes a third controller, a third capacitor and a magnetic rod antenna; the magnetic rod antenna is connected to one end of the third capacitor, the other end of the third capacitor is connected to the input end of the third controller, and the output end of the third controller is connected to the input end of the first controller.

[0030] Beneficial effects: As a key component for signal reception, the magnetic rod antenna has a high sensitivity to wireless signals and can effectively capture weak detonation command signals in complex environments. For example, in underground mines, tunnels and other scenarios where there is obstruction and interference, the magnetic rod antenna can rely on its characteristics to receive as many signals as possible from external control equipment, providing the prerequisite for accurate detonation of detonators. The third capacitor plays a filtering and coupling role in the circuit. On the one hand, it can filter out high-frequency noise and interference signals mixed in the signal received by the magnetic rod antenna, making the signal transmitted to the third controller purer and improving the signal quality. On the other hand, the coupling characteristics of the capacitor help to stably transmit the signal received by the magnetic rod antenna to the third controller, ensuring the stability and reliability of signal transmission and reducing signal attenuation and distortion.

[0031] Furthermore, the reset filter module includes a delayer and a buffer, the input end of the delayer is connected to the output end of the power-on reset module, the output end of the delayer is connected to the input end of the buffer, and the output end of the buffer is connected to the input end of the oscillator.

[0032] Beneficial effect: In this scheme, the delayer is used to receive the reset signal output by the power-on reset module, delay the reset signal, and pass the delayed signal to the buffer. The buffer can isolate the mutual influence between the front and rear circuits, enhance the delayed signal, and transmit it to the oscillator.

[0033] The reset signal output by the power-on reset module may be interfered by high-frequency static electricity, resulting in instantaneous interference spikes. The delay device delays the signal for a certain period of time, allowing the signal to continue to transmit after the interference spike has passed. Because static interference is usually a short pulse, after the delay, the signal received by the subsequent circuit can avoid these interference spikes, thereby effectively reducing the impact of the interference signal on the oscillator.

[0034] After receiving the delayed signal, the buffer can further smooth the signal. It can eliminate some small fluctuations and noise in the signal and make the signal more stable. The combination of delayer and buffer can be flexibly adjusted according to the needs of different systems. By selecting delayers with different delay times and buffers with different parameters, the reset filter module can be adapted to various power-on reset modules and oscillators.

[0035] Furthermore, the ignition control module includes a fifth capacitor, a MOS switch and a third resistor; the third resistor and the MOS switch are connected to the output end of the second controller in sequence, one end of the fifth capacitor is connected to the output end of the second controller, the other end of the fifth capacitor is connected to the MOS switch, and both ends of the MOS switch are respectively connected to the ignition element of the basic electronic detonator.

[0036] Beneficial effect: The third resistor is connected in series between the output end of the second controller and the MOS switch. When the second controller outputs a signal, the third resistor plays a current limiting role. It can prevent excessive current from instantly flowing into the MOS switch and the ignition element of the basic electronic detonator, avoid damage to these elements due to excessive current, extend the service life of the elements, and also reduce the risk of accidental detonation caused by abnormal current, thereby improving the safety of the entire ignition process.

[0037] When the correct detonation signal is not received, the MOS switch is in the off state, and the ignition element of the basic electronic detonator will not be triggered. Only when the second controller outputs a signal that meets the requirements, the MOS switch will be turned on, so that the energy stored in the fifth capacitor is released to the ignition element. This control method effectively prevents mis-detonation caused by external interference or unexpected situations, and ensures the safety of blasting workers and the surrounding environment.

[0038] Furthermore, the first diode and the second diode are either transient suppression diodes or electrostatic protection diodes.

[0039] Beneficial effects: Both transient suppression diodes and electrostatic protection diodes have the ability to respond to high-voltage static electricity instantly. When working normally, they are in a high-resistance state, which hardly affects the normal signal transmission of the circuit; when high-voltage static electricity is generated, they can quickly change to a low-resistance state, quickly discharge the static electricity energy to the ground, and prevent static electricity from damaging sensitive components such as the second controller at the back end, effectively protecting key components in the circuit and ensuring the stable operation of the electronic detonator system. Two types of diodes are available, which can be flexibly configured according to different application scenarios and cost requirements.

[0043] The following is further described in detail through specific implementation methods:

[0047] The second controller IC2 is used to receive the detonation signal processed by the first anti-static interference module from the wireless communication module; the second controller IC2 is used to control the detonation of the basic electronic detonator according to the received detonation signal.

In this embodiment, the first diode B1 and the second diode B2 are transient suppression diodes and electrostatic protection diodes, respectively. When working normally, they are in a high-resistance state, which is understood as an open circuit state. When high-voltage static electricity is generated, B1 and B2 are in a low-resistance state, which is equivalent to short-circuiting the receiving control chip IC1, discharging the static electricity to the ground, and protecting the back-end electronic control module from damage.

[0054] The first protection capacitor C1 and the second protection capacitor C2 are both 1nF, and the breakdown voltage is 50V. When the first controller IC1 generates static electricity, the static electricity will generate high-frequency radiation. The high-frequency radiation is filtered by C1 and C2 to reduce the interference of electromagnetic radiation on the magnetic rod antenna.

[0055] A second anti-static interference module is also provided between the second controller IC2 and the basic electronic detonator.

[0056] The second anti-static interference module includes a power-on reset module, a reset filter module, an oscillator, and an ignition control module;

The second controller IC2 is controlled as the main control chip of the electronic detonator, which is used to receive the instructions of the first controller IC1, control the charging and discharging of the fifth capacitor C5, and feedback to the first controller IC1 for confirmation after receiving the detonation instruction. In this embodiment, the power-on reset module includes a reset resistor, a reset capacitor and a reset diode.

[0062] After the second controller IC2 is powered on normally, the power-on reset outputs the reset signal PRO to reset the chip, and the second controller IC2 is in standby state, waiting to receive instructions from the first controller IC1. The first controller IC1 performs operations such as communication networking, delay time setting, detonation password verification, and charging ignition capacitor on the second controller IC2 and confirms them. The first controller IC1 receives the detonation instruction issued by the magnetic rod antenna, and waits for detonation after confirming the status of the electronic control module. The second controller IC2 receives the detonation instruction by receiving the power supply from the foot line corresponding to the first controller IC1, and enters the oscillator countdown delay state. When the count reaches zero, the ignition control instruction is output, the MOS tube switch is turned off, the fifth capacitor C5 is discharged, and the ignition element ignites the ignition powder.
