The main issue is that operators must be in close proximity to the vehicle, which not only exposes them to higher safety risks but also creates blind spots in complex and harsh working environments such as underground or open-pit mines, hindering precise vehicle control and failing to meet the ever-increasing demands for precision and efficiency in explosive loading operations. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an industrial wireless remote control system for a medicine loading vehicle, comprising: a remote control transmitting system and a remote control receiving system;

[0004] The remote control transmitting system includes an ergonomic grip shell, a universal joystick on the top of the shell, a linear joystick on the side of the shell, a function operation switch, a feedback indicator light, a feedback display screen embedded in the front of the shell, and a control unit inside the shell, which is connected to the wireless transmitting module.

[0005] The remote control receiving system is installed in the operating console of the medicine loading vehicle and includes a wireless communication module and a decoding circuit module. The wireless communication module communicates wirelessly with the wireless transmission module of the remote control transmitting system, and the decoding circuit module is electrically connected to the PLC control module of the medicine loading vehicle through a CAN bus cable.

[0006] Both the remote control transmitting system and the remote control receiving system are equipped with wired control interfaces. The wired control interfaces are connected via a 24V power cable and a CAN bus cable, so that when the radio signal is weak, the medicine loading vehicle can be controlled via the wired control interfaces.

[0007] In one possible implementation, the wireless communication module of the remote control receiving system adopts a dual-CPU dual-decoding circuit module. The dual-CPU dual-decoding circuit module includes a first microprocessor unit and a second microprocessor unit.

[0009] In one possible implementation, the remote control transmitting system integrates a signal interference detection circuit, which is electrically connected to the control unit and triggers automatic shutdown when continuous communication interference is detected.

[0010] In one possible implementation, the feedback display screen is embedded in the front of the housing of the remote control transmitting system. The display screen is electrically connected to the control unit on the main control board of the remote control transmitting system through a signal strength detection module and a battery power detection module, and is used to display the signal strength and battery power in real time.

[0011] In one possible implementation, the housing of the remote control transmitting system is equipped with a parameter setting module and a status display module that are electrically connected to the control unit. The parameter setting module communicates with the PLC control module of the drug loading vehicle through a function operation switch to set control parameters; the status display module displays the performance parameters of the drug loading vehicle in real time through a display screen.

[0012] In one possible implementation, the remote control transmitting system adopts a modular design, including a detachable control board, a power board, and a communication board.

The remote control transmitting system is equipped with a self-test circuit module, which is connected to the communication board and the main control board via test lines. When a communication interruption or hardware failure is detected, an automatic shutdown protection function is triggered.

[0013] In one possible implementation, the wired control interface includes an RJ45 interface and an aviation connector. The RJ45 interface is connected to the PLC control module of the loading vehicle via a CAN bus cable, and the aviation connector is connected to the power module of the loading vehicle via a 24V power cable.

[0014] By employing the above-mentioned technical means, it achieves the following beneficial effects:

[0015] This utility model patent provides an industrial wireless remote control system for a drug loading vehicle. Through wireless remote control, operators can maintain a safe distance from the vehicle, effectively avoiding potential dangers caused by close contact. This improvement significantly reduces the risk of accidents during operation, ensures the safety of operators, and meets the stringent safety requirements for equipment operation in special environments such as mines and tunnels.

[0016] Operators are no longer limited by traditional close-range operation and can flexibly choose appropriate operating positions based on the actual work scenario, especially finding the location with the best field of vision for operation, thus better coping with complex work environments. This flexibility makes the operation of the loading vehicle more convenient and efficient, helping to improve overall work efficiency and quality.

[0017] Furthermore, this wireless remote control system significantly improves the operational efficiency of the loading vehicle. The remote control function reduces the number of times the vehicle needs to move and the operation time during the operation, thus accelerating the loading process. Simultaneously, the system's intelligent functions, such as automatic loading, parameter setting, and status display, enable intelligent management of the loading operation, further enhancing efficiency and accuracy.

[0021] Figure 3 This is a schematic diagram of the feedback display screen provided for an exemplary embodiment of the present invention. Detailed Implementation

[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0023] This utility model relates to an industrial wireless remote control system for explosive loading vehicles, aiming to improve the safety, flexibility, and efficiency of explosive loading vehicle operation in blasting environments such as mines and tunnels. Figures 1 to 3 As shown, the system mainly consists of a remote control transmitting system and a remote control receiving system. The remote control transmitting system is responsible for sending control commands, while the remote control receiving system is installed on the medicine loading vehicle to receive and decode the commands. The decoded signals are then transmitted to the medicine loading vehicle, thereby achieving precise control of the medicine loading vehicle.

[0024] The remote control launch system features an ergonomic grip shell design, which fully considers the operator's grip comfort and ease of operation. This allows the operator to hold the remote control launch system stably and comfortably, effectively reducing fatigue caused by prolonged operation and providing a good foundation for the remote control operation of the medicine loading vehicle.

[0025] like Figure 2 As shown, a universal rocker arm and a linear rocker arm are located on the top of the casing. The universal rocker arm is mainly used to control the direction and speed of the loading cart. Operators can flexibly push the universal rocker arm to move the loading cart in different directions and adjust its speed. The linear rocker arm is used to control the extension and retraction of the loading tube, thereby precisely adjusting the position of the loading tube to meet the needs of the loading operation. In addition, multiple function operation switches are located on the side of the casing. These switches correspond to different functions of the loading cart, such as starting loading, stopping loading, and cleaning operations. Operators can control various functions of the loading cart through simple button operations.

[0026] The remote control launch system is also equipped with feedback indicator lights and a feedback display screen embedded in the front of the housing. For example, the feedback indicator lights are LED lights, and the feedback display screen is a 3.5-inch LCD screen. The feedback indicator lights can intuitively display key status information of the loading vehicle, such as the equipment's operating status and fault alarms, allowing operators to quickly understand the basic working status of the loading vehicle when operating it remotely. The feedback display screen can display the performance parameters of the loading vehicle in real time, such as loading speed, loading amount, and loading pressure, providing operators with richer and more detailed information to help them make accurate operational decisions based on the actual situation on site.

[0027] Inside the casing of the remote control transmitting system is a control unit connected to the wireless transmitting module. The control unit receives input signals from the universal joystick, linear joystick, and function operation switches, processes and encodes them, and then transmits the control commands wirelessly via the wireless transmitting module. This process enables operators to wirelessly remotely control the medicine loading vehicle, allowing them to flexibly control various operations within a certain distance. It should be noted that the procedural operations involved in receiving, transmitting, and processing control commands in this embodiment can all employ methods known in the art and are not the subject of this patent.

[0028] In addition to wireless control, the remote control transmitting system also has a wired control interface. When in environments with weak radio signals, such as underground, operators can use a 24V power cable and a CAN bus cable to wire the remote control transmitting system to the remote control receiving system on the loading vehicle, thereby achieving stable control of the loading vehicle and ensuring the smooth progress of the loading operation.

[0029] Furthermore, the remote control receiving system is installed inside the control panel of the loading vehicle, and one of its core components is the wireless communication module. This module communicates wirelessly with the wireless transmitting module of the remote control transmitting system, receiving wireless control commands sent by the remote control transmitting system and transmitting them to the decoding circuit module. The wireless communication module employs advanced communication technology and anti-interference measures to ensure that the loading vehicle can stably and reliably receive commands from the remote control transmitting system in complex environments such as mines and tunnels, thereby achieving precise remote control.

[0030] Furthermore, the decoding circuit module in the remote control receiving system is electrically connected to the PLC control module of the loading vehicle via a CAN bus cable. To improve the accuracy of wireless communication signal reception, the decoding circuit module adopts dual-CPU dual-decoding technology, comprising a first microprocessor unit and a second microprocessor unit, which are connected in parallel through a redundant verification circuit. This design enables dual decoding and verification of the radio signal during signal reception, effectively reducing the signal error rate, improving the reliability of signal reception, and ensuring that the loading vehicle can accurately execute the instructions issued by the operator through the remote control transmitting system, thereby enhancing the safety and accuracy of the loading operation.

[0031] According to a preferred embodiment of this application, the top of the housing of the remote control launching system is equipped with an emergency stop button, which is directly connected to the emergency braking control module of the loading vehicle via hardwiring. In an emergency, when the operator presses the emergency stop button, a signal is quickly transmitted to the loading vehicle, immediately stopping all actions of the loading vehicle, including the extension and retraction of the loading tube and the movement of the loading vehicle, thereby effectively avoiding potential dangers and ensuring the safety of on-site personnel and equipment.

[0032] The remote control launch system integrates a signal interference detection circuit, which is electrically connected to the control unit. When continuous communication interference is detected, the signal interference detection circuit triggers an automatic shutdown function, causing the remote control launch system to shut down promptly. This prevents equipment malfunctions due to signal interference and further improves the safety of the explosive loading operation.

[0033] The feedback display screen of the remote control launch system is electrically connected to the control unit through a signal strength detection module and a battery level detection module, enabling real-time display of signal strength and battery level. Operators can select a location with good signal strength based on the signal strength indication, ensuring the reliability of remote control operation. Simultaneously, the battery level display function reminds operators to replace batteries in a timely manner, preventing the remote control launch system from suddenly malfunctioning due to insufficient battery power, which could disrupt the normal operation of the explosive loading process.

[0034] like Figure 3As shown, the remote control launching system's casing houses a parameter setting module and a status display module electrically connected to the control unit. The parameter setting module communicates with the PLC control module of the loading vehicle via function operation switches. Operators can set loading parameters, such as loading amount and loading speed, according to the specific requirements of the loading operation, through the function operation switches on the remote control launching system, achieving personalized control of the loading vehicle. The status display module displays the loading vehicle's performance parameters in real time on a screen, such as the pressure of the loading tube, loading speed, and the amount of loading, allowing operators to understand the loading vehicle's working status at any time, facilitating timely adjustments to operating strategies, and improving the efficiency and quality of the loading operation.

[0035] Furthermore, the remote-controlled launch system adopts a modular design, including a detachable control board, power board, and communication board. The control board is installed inside the housing via slots, the power board is fixed to the inner wall of the housing with conductive adhesive, and the communication board is connected to the wireless launch module via an RF connector. This modular design not only facilitates system maintenance and upgrades but also improves system reliability and maintainability. In addition, the remote-controlled launch system includes a self-test circuit module, which is connected to the communication board and main control board via test lines. When a communication interruption or hardware failure is detected, the self-test circuit module triggers an automatic shutdown protection function, promptly avoiding potential safety hazards caused by equipment failure and ensuring the safe operation of the dynamite loading process.

[0036] Both the remote control transmitting and receiving systems are equipped with wired control interfaces, including an RJ45 interface and an aviation connector. The RJ45 interface connects to the PLC control module of the loading vehicle via a CAN bus cable for transmitting control commands and status information. The aviation connector connects to the power module of the loading vehicle via a 24V power cable, providing a stable power supply to the remote control transmitting system. In situations where radio signals are weak or where a wired connection is required to ensure stability, operators can use these wired control interfaces to quickly and easily establish a wired connection between the remote control transmitting system and the loading vehicle, ensuring the smooth operation of the loading process.

[0037] The wireless remote control system provided by this utility model will be further described in detail below, taking into account the remote control operation process of the medicine loading vehicle.

[0038] Before starting the remote control operation of the loading vehicle, the operator needs to check the connection between the remote control transmitter and receiver systems to ensure smooth wireless communication or a secure wired control interface connection. At the same time, the operator should check whether the remote control transmitter's battery has sufficient power and whether all equipment on the loading vehicle is in normal working order, making full preparations for the loading operation.

[0039] The operator sends a start command to the loading vehicle via the control unit on the remote control transmitting system. Upon receiving the command, the control unit of the remote control transmitting system transmits it to the remote control receiving system on the loading vehicle via the wireless transmitting module. The remote control receiving system receives the command via the wireless communication module, decodes it via the decoding circuit module, and then transmits the start signal to the PLC control module of the loading vehicle. The loading vehicle then starts upon receiving the start command.

[0040] After the delivery vehicle is started, the operator can control its direction and speed using a universal joystick on the remote control system. When the operator pushes the joystick, the change in its position is detected by the control unit. The control unit calculates the direction and speed commands for the delivery vehicle based on the joystick's position change and sends them to the delivery vehicle via a wireless transmission module. Upon receiving the commands, the delivery vehicle's driving system adjusts its direction and speed accordingly, enabling flexible movement of the delivery vehicle at the work site.

[0041] During the loading operation, operators need to precisely control the loading tube. Using a linear joystick on the remote control system, operators can control the extension and retraction of the loading tube. The position signal of the linear joystick is received by the control unit, converted into an action command for the loading tube, and transmitted to the loading vehicle via the wireless transmission module. The loading vehicle's loading system, based on the received command, controls the extension and retraction of the loading tube to accurately load the explosive into the predetermined position.

[0042] Operators can set loading parameters, such as loading amount and loading speed, through the function operation switches and parameter setting module on the remote control transmitting system. The set parameters are transmitted wirelessly to the PLC control module of the loading vehicle and stored in the module. During the loading operation, the PLC control module of the loading vehicle controls the loading process according to the set parameters, while simultaneously collecting the vehicle's performance parameters in real time, such as the loaded amount, loading speed, and loading pressure, and transmitting these parameters back to the remote control receiving system via a CAN bus cable. The remote control receiving system sends the received parameter information to the remote control transmitting system, and finally displays it in real time on the feedback display screen of the remote control transmitting system, allowing operators to understand the progress of the loading operation at any time and achieve precise monitoring and management of the loading process.

[0043] In case of an emergency during the loading operation, such as a malfunction of the loading vehicle or a dangerous surrounding environment, the operator should immediately press the emergency stop button on the remote control system. The signal from the emergency stop button is transmitted directly to the emergency braking control module of the loading vehicle via hardwire. Upon receiving the emergency stop signal, the loading vehicle will immediately stop all actions, including the extension and retraction of the loading tube, the movement of the loading vehicle, and the loading operation, to ensure on-site safety.

[0044] When the loading operation is completed or needs to be paused, the operator sends a stop command via the remote control system. Upon receiving the command, the control unit of the remote control system transmits it to the loading vehicle via the wireless transmission module. The loading vehicle then stops operating upon receiving the stop command. The operator can then perform necessary checks and maintenance on the loading vehicle to ensure it is in good working order and ready for the next loading operation.

[0045] Through the above specific embodiments, the industrial wireless remote control system for explosive loading vehicles of this utility model can effectively improve the safety, flexibility and efficiency of explosive loading vehicle operation, meet the strict requirements for the operation performance of explosive loading vehicles in blasting operation environments such as mines and tunnels, and provide a reliable and efficient solution for blasting operations.
