Abstract
Description
Technical Field
[0001] This invention relates to the field of mine rockburst detection technology, and more specifically, to an intelligent triggering device and method based on the PASAT-M detection system. Background Technology
[0002] Rockburst is a dynamic disaster that occurs during coal mining. This disaster usually occurs when the strength that the coal and rock mechanical system can withstand reaches or exceeds its own strength limit. It is the instantaneous release of elastic energy accumulated in the coal and rock mass, which causes sudden and violent damage in the mine roadway or mining face, resulting in damage to the mine roadway and equipment, and even casualties.
[0003] In recent years, coal mines have gradually shifted towards deep mining, and the intensity of mining has increased, making the threat of rockburst disasters to mines increasingly serious. Several severe rockburst accidents have occurred in recent years. This severe rockburst situation has placed higher demands on the scientific nature and effectiveness of rockburst prevention and control technologies.
[0004] The PASAT-M (Impact Hazard) detection system can invert the static load stress and distribution of coal and rock mass based on the positive correlation between the stress concentration degree inside the coal body and the wave velocity of seismic waves inside the coal body, and then evaluate the impact hazard level and delineate the hazard area.
[0005] In order to obtain the initial time of seismic wave excitation during field detection, the PASAT-M detection system requires each trigger shot to be connected to the detection equipment via a signal cable before detonation, with each shot connected sequentially. As the position of the blast hole changes, the wiring personnel need to manage and lay the signal cables, which seriously affects the detection efficiency. Furthermore, the signal lines leading from the blast hole, the detonator's initiation wire, and the detonator wire all need to be connected before detonation. The signal cables are energized in the standby state, and the multiple wires are difficult to distinguish during connection, posing a safety hazard of incorrect connection. Because the signal lines need to be wound around the explosive charge, there is a possibility of signal lines coming loose during installation, causing the equipment to fail to trigger and produce invalid shots.
[0006] In view of the problems encountered in the triggering process during the use of the PASAT-M detection system, it is of great significance to design and implement an intelligent triggering device adapted to the existing PASAT-M impact hazard detection system. Summary of the Invention

[0055] Example
[0056] like Figure 1 As shown, this embodiment provides an intelligent triggering device based on the PASAT-M detection system, which includes: an electronic gun sensor, a gun mechanism sensor, a trigger sensor, a signal conditioning circuit, an analog-to-digital converter, a processor, a display module, buttons, a control output module, a storage module, a communication module, and a power supply.
[0057] The electronic gun sensor, gun mechanism sensor, and trigger sensor are used to collect electronic gun sensing signals, gun mechanism sensing signals, and trigger sensor signals and transmit them to the signal conditioning circuit. The signal conditioning circuit processes the collected signals and transmits them to the analog-to-digital converter. After processing by the analog-to-digital converter, the signals are sent to the processor. The processor performs human-machine interaction through buttons and a display module. The signals processed by the processor are transmitted through the control output module to control the acquisition of the PASAT-M detection system. The processor saves the collected signals through a storage module. The processor is connected to a communication module, which can extract the signal information. The power supply is used to provide power.

The intelligent triggering device allows for manual interaction through the display module (LCD) and buttons to establish the survey line task and survey line number, select the trigger source and set the trigger threshold corresponding to each trigger source, and set the sampling interval, sampling rate, data storage format, and trigger output signal parameters. After the settings are completed, the intelligent triggering device enters the real-time acquisition and storage state. The processor allocates the corresponding buffer and storage space according to the set parameters, and the trigger selection circuit switches the input signal of the data converter to the processor, reducing the circuit gain of the input path of the artillery sensor. By clicking the acquisition button, the time slice of the current acquisition is recorded. The signal input from the gun sensor passes through a surge protector, isolator, signal conditioner, and second filter before entering the second programmable amplifier. After passing through the second programmable amplifier, the signal is input into the analog-to-digital converter circuit. The processor drives the analog-to-digital converter, analyzes the acquired signal value after conversion, and automatically adjusts the gain of the second programmable amplifier to improve the signal accuracy. The processor compares the acquired signal value with the set threshold. If the acquired signal value is greater than or equal to the acquisition threshold, the processor will output a set trigger output signal to the trigger monitoring module MWP and save the signal waveform and corresponding time of the current acquisition.
[0064] like Figure 4 As shown, the PASAT-M detection system includes a trigger monitoring module (MWP) and multiple data acquisition substations (MPTs) connected sequentially via optical fibers. The trigger monitoring module (MWP) is connected to a trigger signal generator and to the first data acquisition substation (MPT). Each acquisition substation is connected to one substation sensor. The trigger monitoring module (MWP) is connected to a handheld controller (PDA) via Bluetooth, and the collected data can be uploaded to the handheld controller (PDA) for display in real time via Bluetooth.
[0065] The trigger end of the intelligent triggering device is connected in series with a detonator and then connected to a firing device, which includes an electronic cannon and a traditional cannon mechanism.
