Description
TECHNICAL FIELD
[0001] The present application generally relates to the technical field of coal mining. More particularly, the present application relates to a control system for linkage between a crusher and a shuttle car. BACKGROUND
[0002] In the mining operation, the crusher and the shuttle car are the key production equipment. The shuttle car is mainly responsible for transporting the ore and other materials to the crusher, and the crusher is used to crush the ore and other materials and then transport them to the collecting device through the conveying device. At present, the above two devices usually adopt independent operation mode, and lack effective cooperative control mechanism, which leads to the difficulty in accurately matching the time of the crusher completing the material crushing and the shuttle car reaching the material receiving position in the production process, and low work efficiency. For example, the shuttle car may arrive too early and be forced to wait until the crusher operation is completed, or the crusher may be idle for a long time after completing the crushing because the shuttle car does not arrive in time. The waiting and idling between the above devices significantly prolongs the overall process time of material crushing and transportation, and restricts the improvement of mining efficiency. Moreover, the frequent waiting, idling and unnecessary start-stop operation caused by poor device cooperation significantly increases the energy consumption of the crusher and the shuttle car. This not only increases the production and operation cost of the mine, but also causes energy consumption, which does not meet the development requirements of green mine and energy saving and emission reduction.
[0003] Therefore, there is an urgent need to provide a control system for linkage between a crusher and a shuttle car, so as to link the two to improve work efficiency and save energy consumption. CONTENT OF THE INVENTION

[0007] In some embodiments, further comprising: two direction indicators arranged at the feeding port of the crusher and the loading position of the shuttle vehicle, respectively, for indicating the driving direction of the shuttle vehicle.
[0008] In some embodiments, the controller is configured to generate a control instruction for starting the crusher when the shuttle vehicle reaches the loading position of the crusher or the distance between the two reaches a preset value, and generate a control instruction for stopping the operation of the shuttle vehicle and the crusher when the distance is less than a safety threshold.
[0009] In some embodiments, the starting mechanism comprises: a shuttle vehicle controller configured to receive the control instruction from the controller to control the start and stop of the shuttle vehicle and the driving path of the shuttle vehicle; and a crusher controller configured to receive the control instruction from the controller to control the start and stop of the crusher and the operation parameters of the crusher.

[0026] The specific embodiments of the application will be described in detail below with reference to the accompanying drawings.
[0027] As Figure 1 shown, in some embodiments, the application discloses a crusher and shuttle vehicle linkage control system 100, comprising: a positioning assembly 101 comprising an ultra-wideband (UWB) identification card fixed on the crusher and the shuttle vehicle, and an ultra-wideband (UWB) base station for communication connection with the ultra-wideband (UWB) identification card and calculation of coordinates; the positioning assembly 101 is used for detecting the position information of the crusher and the shuttle vehicle; a first material detection sensor 102 is arranged on the crusher and is used for detecting the amount of material in the crusher; a controller 103 is used for receiving the position information of the crusher and the shuttle vehicle detected by the positioning assembly 101 and the material information detected by the first material detection sensor 102, and generating a control instruction according to the information; and a starting mechanism 105 connected to the power system of the shuttle vehicle and the crusher respectively, which controls the start and stop of the shuttle vehicle and the crusher in response to the control instruction.
[0028] The control system 100 of the crusher and shuttle vehicle linkage in the scheme comprises a positioning assembly 101, a first material detection sensor 102, a controller 103 and a starting mechanism 105. Specifically, the positioning assembly 101 in the scheme comprises an ultra-wideband (UWB) identification card fixed on the crusher and the shuttle vehicle, and an ultra-wideband (UWB) base station connected with the ultra-wideband (UWB) identification card. In use, the UWB identification card emits wireless signals in real time, and the base station calculates the three-dimensional coordinates of the equipment through the time difference or phase difference of the received signals, and the positioning accuracy can reach centimeter level. That is, the positioning assembly 101 in the scheme can dynamically monitor the relative position, distance and motion trajectory of the crusher and the shuttle vehicle, and provide data for linkage control. In addition, the control system 100 in the scheme further comprises a first material detection sensor 102 arranged on the crusher, which can detect the amount of material in the crusher.
[0029] The controller 103 in the scheme is in communication connection with the positioning assembly 101 and the first material sensor, and can receive the position information sent by the positioning assembly 101 and the amount of material detected by the first material detection sensor 102, and generate control instructions according to the preset logic. In addition, the controller 103 is also in communication connection with the starting mechanism 105, the starting mechanism 105 is connected with the power system of the shuttle vehicle and the crusher respectively, and the starting mechanism 105 responds to the control instructions of the controller 103 in real time to control the start and stop of the shuttle vehicle and the crusher and other precise actions.
[0030] In use, the control system 100 of the scheme can determine whether the shuttle vehicle needs to transport material to the crusher to perform crushing operation according to the amount of material in the crusher detected by the first material detection module, and then determine the time point of starting the shuttle vehicle according to the distance between the crusher and the shuttle vehicle. Specifically, when the amount of material in the crusher is detected to be higher than the preset material amount, it means that there is a large amount of unbroken material in the crusher, which does not have space to carry new material, so the shuttle vehicle is controlled to be in a stop running state to avoid the shuttle vehicle feeding material in advance and causing material accumulation. When the amount of material in the crusher is detected to be lower than the preset material amount, it means that the crusher has enough space to carry new material, so the starting time of the shuttle vehicle is determined according to the position information of the shuttle vehicle and the crusher detected by the positioning assembly 101. For example, when the distance between the shuttle vehicle and the crusher is greater than or equal to the set distance, the shuttle vehicle is triggered to start. When the distance between the shuttle vehicle and the crusher is less than the set distance, the starting time of the shuttle vehicle is dynamically determined according to the preset material crushing completion time (such as the crushing time based on historical data or real-time calculation), so as to ensure that the crusher has just completed the previous crushing operation when the shuttle vehicle arrives.
[0031] The scheme realizes seamless connection of the crushing and transportation processes by the dual control mechanism of material quantity threshold judgment and distance dynamic matching, and significantly improves the operation efficiency and synergy of the mine exploitation.
[0032] In some embodiments, the controller is configured to generate a control instruction for starting the crusher when the shuttle vehicle reaches a material receiving position of the crusher or the distance between the two reaches a preset value, and generate a control instruction for stopping the operation of the shuttle vehicle and the crusher when the distance is less than a safety threshold.
[0033] In the scheme, the controller is configured to obtain the position information of the shuttle vehicle and the crusher in real time through the positioning assembly 101, and generate key control instructions accordingly. In a specific embodiment, when the first material detection module detects that there is no material in the crusher and the crusher is in a stopped state, the controller 103 generates a control instruction for starting the operation of the crusher when the positioning assembly detects that the shuttle vehicle reaches a preset material receiving position of the crusher feeding port or the real-time distance between the shuttle vehicle and the crusher is shortened to a first preset threshold.
[0034] In another specific embodiment, although the shuttle vehicle does not reach the precise material receiving point (the preset material receiving position of the crusher feeding port), the real-time distance between the shuttle vehicle and the crusher is shortened to a second preset threshold, at which time the controller 103 calculates the estimated arrival time of the shuttle vehicle and simultaneously starts the crusher to ensure seamless connection of the just-in-time unloading.
[0035] In addition, the scheme also sets a safety mechanism, that is, once the positioning assembly 101 detects that the real-time distance between the shuttle vehicle and the crusher is less than a preset safety threshold, the controller 103 will immediately generate an emergency stop instruction to force the shuttle vehicle and the crusher to stop running, regardless of the current working state of the equipment. It is worth noting that the safety threshold in the scheme is strictly based on the physical size of the equipment, the safety braking distance required by the braking system, and the necessary operation safety gap, and the core purpose is to ensure that even in extreme working conditions (such as sensor delay or equipment out of control), the system still has sufficient buffer space to avoid collision accidents.
[0036] In a specific embodiment, the first material detection sensor 102 is a vibration sensor, which obtains the material quantity by detecting the weight of the crusher load, and controls the shuttle vehicle to move from the loading position to the crusher when the material quantity reaches a preset value.
[0037] In the present scheme, the first material detection sensor 102 is a vibration sensor, which can be installed at the key load components of the crusher, such as the motor shaft, the crushing cavity support structure or the transmission belt pulley. In use, the vibration sensor collects the vibration signals of the crusher in real time through its built-in accelerometer or piezoelectric ceramic element to determine the amount of material in the crusher. Specifically, when the crusher is empty, the vibration frequency is high and the amplitude is small; as the amount of material increases, the load increases, the vibration frequency decreases and the amplitude increases. The vibration sensor converts the real-time vibration data into equivalent load weight through signal processing algorithms such as Fourier transform and transmits it to the controller 103. In addition, the vibration sensor in the present scheme does not need to directly contact the material, which can avoid the failure of traditional mechanical contact sensors caused by material impact and wear, effectively improving the long-term reliability.
[0038] In a specific embodiment, the starting mechanism 105 includes a shuttle car controller configured to receive control instructions from the controller 103 to control the start and stop and travel path of the shuttle car, and a crusher controller configured to receive control instructions from the controller 103 to control the start and stop and operating parameters of the crusher.
[0039] The starting mechanism 105 in the present scheme serves as the execution layer of the crusher and shuttle car linkage control system 100, which is composed of a shuttle car controller and a crusher controller. The two communicate with the controller 103 through hardware interfaces (such as relays, CAN bus) in both directions, can directly connect to the equipment power system and respond to the instructions of the controller 103, and realize the precise execution of equipment action. Specifically, the shuttle car controller, as the core controller of the shuttle car power system, mainly undertakes the tasks of start and stop control and travel path control. It not only can receive instructions from the controller 103 to control the start, stop and braking of the shuttle car motor, realize the precise start and stop of the equipment, but also can generate steering instructions through the built-in path planning algorithm to control the travel direction and trajectory of the shuttle car, ensuring that it travels to the material receiving position of the crusher or returns to the loading position according to the preset route. The crusher controller is responsible for the start and stop control and operating parameter adjustment of the crusher, where the operating parameter adjustment can be speed adjustment and crushing power adjustment.
[0040] As shown in Figure 3 In a specific embodiment, a non-contact electromagnetic induction sensor 107 is also provided on the crusher, which is used to monitor the material humidity and feed back to the controller 103 to adjust the crushing power of the crusher.
[0041] In the present scheme, the electromagnetic induction sensor 107 is arranged outside the crusher feed inlet or cavity and connected with the controller 103. The electromagnetic induction sensor 107 measures the humidity by detecting the change of the dielectric constant of the material, which can detect the material humidity without directly contacting the material, and is used to monitor the material humidity and feed back to the controller 103.
[0042] In use, the controller 103 matches the corresponding power level according to the current humidity value, and adjusts the motor frequency converter parameters or hydraulic system pressure through the crusher controller to achieve dynamic switching of crushing power. For example, when the detected humidity is in the first humidity range, the crusher is controlled to operate in low power mode; when the detected humidity is in the second humidity range, the crusher is controlled to operate in medium power mode; and when the detected humidity is in the third humidity range, the crusher is controlled to operate in high power mode.
[0043] like Figure 2 As shown, in one specific implementation, it further includes: a second material detection sensor 106, which is installed on the shuttle car to detect whether the shuttle car is loaded with material and send a status signal to the controller 103; the controller 103 is configured to control the shuttle car to stop at the feed inlet of the crusher or the loading point of the shuttle car according to the status signal. It also includes: two direction indicator lights, respectively installed at the feed inlet of the crusher and the loading point of the shuttle car, to indicate the direction of travel of the shuttle car.
[0044] In this design, a second material detection sensor 106 is installed on the shuttle car to detect whether the shuttle car is currently carrying material. This second material detection sensor 106 is connected to the controller 103 and sends the detected status signal to the controller 103. In addition, this design provides a direction indicator light at the crusher feed inlet and the shuttle car loading point to indicate the direction of the shuttle car's movement.
[0045] In operation, when the second material detection sensor 106 detects that the shuttle car is loaded, the controller 103 sends a command to guide the shuttle car to stop at the crusher's feed inlet. Simultaneously, an indicator light at the crusher's feed inlet illuminates, facilitating the shuttle car's better positioning at the crusher and ensuring timely material delivery for crushing, thus maintaining production continuity. When the second material detection sensor 106 detects that the shuttle car is unloaded, the controller 103 directs the shuttle car to the loading area to load new material. At the same time, an indicator light at the crusher's feed inlet illuminates, again facilitating the shuttle car's better positioning at the loading area. This ensures the shuttle car can efficiently participate in material transfer, reducing equipment downtime and improving overall operational efficiency.
[0046] Of course, those skilled in the art will understand that the shuttle car is equipped with a device for acquiring indicator light signals, which sends the acquired indicator light signals to the controller, and the controller sends control commands based on the signal information.
[0047] In one specific implementation, a noise sensor is installed on the crusher to monitor the operating noise of the crusher and transmit it to the controller 103; when the noise of the crusher exceeds the preset noise value, the controller 103 controls the crusher to reduce its speed.
[0048] Since the crusher will produce different degrees of noise during operation, and the intensity of the noise is often closely related to the running state of the equipment. The present scheme can monitor the running noise of the crusher in real time by setting a noise sensor on the crusher, and transmit the monitored noise data to the controller 103. The controller 103 is built-in with a preset noise value, which is set according to the noise intensity of the normal operation of the crusher and the relevant safety and environmental protection standards. When the noise data received by the controller 103 exceeds the preset noise value, the controller 103 will immediately determine that the crusher may have abnormal operation or overload and the like. At this time, the controller 103 sends an instruction to the motor control system 100 of the crusher to reduce the speed of the crusher. After reducing the speed, the running intensity of each component inside the crusher is weakened, and the speed and intensity of material crushing are relatively reduced, thereby effectively reducing the noise level.
[0049] In a specific embodiment, the control system 100 further comprises a dust sensor arranged at the inlet of the crusher for detecting the dust concentration, and a spray dust reduction device linked with the dust sensor, which automatically starts spraying when the concentration exceeds the limit and closes after reaching the standard.
[0050] Since the material will produce dust when crushing in the crusher, in order to effectively control the dust, the control system 100 in the present scheme is provided with a dust sensor and a spray dust reduction device in communication connection with the controller 103. Specifically, the dust sensor is installed at the inlet of the crusher and the shuttle car discharge port to monitor the dust concentration in real time. The spray dust reduction device includes a spray head, a water tank, a water pump and a control system 100. When the spray dust reduction device receives a start signal, the water pump sprays water to form a water mist to adsorb dust particles and make them settle. In use, the spray dust reduction device is linked with the dust sensor, and when the dust concentration exceeds the preset limit, the sensor sends a signal to the controller 103, and the controller 103 starts the spray dust reduction device to reduce the dust concentration. When the concentration decreases to the standard level, the controller 103 closes the spray device to achieve automatic control.
[0051] In a specific embodiment, a laser particle size analyzer is installed at the discharge port of the crusher to detect the particle size of the crushed material in real time and transmit it to the controller 103, and the controller 103 adjusts the operation parameters of the crusher based on the detection structure.
[0052] In this scheme, a laser particle size analyzer is installed at the discharge port of the crusher. The particle size of the crushed material can be detected in real time and transmitted to the controller 103. After receiving the data, the controller 103 automatically adjusts the operating parameters of the crusher, such as the rotation speed and crushing intensity, according to the preset particle size standard and process requirements. At the same time, the analyzer continuously monitors the particle size to ensure that the adjusted material particle size meets the requirements. This system realizes real-time monitoring and automatic control of the crushing process, improves product quality and stability, and reduces defective products.
