Description

Technical Field

[0001] This utility model relates to the field of mining equipment control technology, specifically to a wireless remote control device for an explosion-proof mining drilling rig. Background Technology

[0002] In mining operations such as coal mining, drilling rigs are extremely important equipment used for critical tasks such as borehole decompression, gas extraction, and geological exploration. Currently, most mining drilling rigs have their control consoles located at the rear of the rig, requiring operators to work at close range. However, the underground working environment is complex and dangerous, and coal and gas outbursts, water inrushes, and other disasters frequently occur during drilling. In the event of a gas outburst or water inrush at the borehole opening, the personal safety of operators working at close range will be seriously threatened.

[0003] While some existing wireless remote controllers are used in mining drilling rigs, they suffer from numerous problems. Current mainstream wireless remote controllers primarily use radio frequency (RF) and Bluetooth communication methods as data exchange links. While RF communication offers long transmission distances and strong anti-interference capabilities, its bandwidth is low, making it difficult to meet the needs of transmitting video from the work site. Bluetooth communication has the advantage of low power consumption, but its transmission rate is low, its transmission distance is short, and its anti-interference capability is weak. These problems prevent existing wireless remote controllers from effectively meeting the diverse needs of remote control of drilling rigs in actual operations. Furthermore, existing wireless remote controllers have relatively simple functions and lack comprehensive safety measures during control, failing to fully ensure the safety of drilling operations.

After a 12V DC input, the first power supply module converts it to 5V to power the first wireless communication unit, the first data acquisition unit, and the human-machine interaction unit. The 5V voltage is then converted to 3.3V by the second power supply module to power the first controller, thus constructing a hierarchical power supply system to adapt to the voltage requirements of different units.

C5 and C6 are connected in parallel at the output terminal of the first low-dropout linear regulator chip to form an output filter network, used to further suppress high-frequency noise and transient fluctuations in the output voltage, providing a reliable 5V power supply for the subsequent circuits. The 5V output voltage is further used as the input of the second-stage voltage conversion circuit. C7 and C8 are connected in parallel at the output of the second low-dropout linear regulator chip to form the second-stage output filter circuit, which is used to decouple and filter the 3.3V output voltage, effectively reducing output ripple and improving voltage stability to meet the accuracy and stability requirements of the 3.3V power supply for low-power loads at the downstream end.

[0021] In this embodiment, the first controller within the transmitter employs an STM32F407 controller based on the ARM architecture.

This signal data includes operation command input status, battery remaining power information, wireless communication link quality, environmental sensor feedback, and operational status feedback signals such as fault codes and action confirmation signals from the drilling rig itself. The first controller converts the processed operation input signals into standardized drilling rig control commands. Furthermore, the transmitter in this embodiment also includes a scheduling module, allowing only one high-priority command to execute at a time, while other low-priority commands are temporarily stored or discarded. When the emergency stop button is detected being pressed, the system immediately interrupts all current command outputs, generates an emergency stop data frame, and sends it first, ensuring that the drilling rig's power output is cut off in the shortest possible time.

[0022] See Figure 5 In this embodiment, the human-machine interface unit adopts a serial communication type touch screen, which is connected to the first controller via a UART interface. This serial communication type touch screen provides a visual operating interface for the operator, displaying in real time information such as the current working mode, the action commands being executed, the remaining battery power, the wireless signal strength, and system faults. It also allows users to enter a settings mode via a settings button to perform functions including channel selection, control sensitivity adjustment, and dead zone configuration, thus achieving two-way interaction between the human and machine.

The second terminal of the second resistor R19 and the RGND port of the RSM485M chip are grounded. The first controller sends data to the RSM485 chip via the U1_TX port. The RSM485 chip converts the received TTL level signal into a differential signal conforming to the RS-485 standard and transmits it to the serial communication touch screen. Simultaneously, data returned from the serial communication touch screen is converted back to TTL level by the RSM485 chip and transmitted to the first controller via the U1_RX port, completing bidirectional data exchange. Furthermore, by setting the transient voltage suppression diode D3 and the terminating matching resistor R25, the anti-interference capability and transmission stability of the communication circuit can be effectively improved, making it suitable for serial communication touch screen interactive applications in various complex electromagnetic environments.

The IN10 port serves as the analog signal input terminal. R19 is used for current limiting and impedance matching to ensure signal transmission stability and suppress reflection interference. A 100nF capacitor is connected in parallel between the ADC input terminal and ground to filter out high-frequency noise and transient interference, improving the purity of the input signal. Additionally, resistors R16 (1kΩ) and R25 (300kΩ) are connected between the ADC input and ground, forming a voltage divider network to adjust the input signal amplitude and ensure it remains within the ADC's linear operating range.

At the same time, it supports a video input interface, which can be connected to a camera module to realize the on-site image acquisition and transmission during drilling operations.

[0030] During operation, the transmitter completes a self-test upon power-on. Operators generate corresponding electrical signals by manipulating buttons, joysticks, and other components on the remote transmitter. The transmitter's analog and digital acquisition units collect these signals, generate corresponding control command data, and transmit it to the receiver via wireless communication. The receiver receives the command data and drives the corresponding actuators of the drilling rig according to the command content, achieving remote control of the drilling rig's operating status. In case of an emergency, the operator presses the emergency stop button. The transmitter immediately generates an emergency stop command and transmits it to the receiver via wireless communication. Upon receiving the emergency stop command, the receiver immediately cuts off the drive signals to the actuators, stopping all drilling rig operations and enabling rapid response in emergency situations. If no valid signal is received from the transmitter within a preset time period, it is determined that the wireless communication link is interrupted or the signal is lost. The controller in the receiver automatically triggers the safety shutdown mechanism, stopping all drilling rig operations and ensuring the equipment remains safe in an uncontrolled state.
