Description

Technical Field

[0001] This invention relates to the field of intelligent management technology, and in particular to an intelligent management system based on weighing and transporting mining vehicles. Background Technology

[0002] Vehicle weighing management is a crucial aspect of modern industrial production and logistics transportation. Accurate weighing data helps reduce transportation risks. Through a weighing management system, companies can promptly detect and address overloading situations, avoiding traffic accidents and transportation losses caused by overloading, thus safeguarding the company's safe production and economic interests.

[0003] However, for mines, the dust is high and the road surface is uneven. During transportation, the road conditions change greatly, making it difficult to predict transportation risks.

[0004] Chinese Patent Publication No. CN115358685B discloses a mine transportation management system and method, including the following steps: acquiring mine mining information and various data information of vehicles; dividing mine transportation tasks according to the various data information; allocating vehicles for transportation according to the divided transportation tasks; sending transportation tasks to vehicles, and if the vehicle confirms the allocation, the task allocation is successful; if the vehicle cancels the allocation, the next vehicle is reassigned until the vehicle confirms the allocation; continuing to allocate the next task until all tasks are fully allocated. This invention divides and allocates mine mining tasks in a way that meets practical requirements, tracks vehicle location information in real time through a positioning module, and confirms the task allocation status through the return value of a wireless transmission module, cyclically traversing and allocating transportation tasks to vehicles, thereby reducing transportation costs.

[0005] However, the above-mentioned plan does not incorporate the carrying capacity of the mine passage into the overall management. When transferring goods, it is impossible to effectively manage the transportation process, which leads to the loss of goods during transportation and reduces the management efficiency of mine vehicles. Summary of the Invention

[0006] Therefore, this invention provides an intelligent management system based on weighing and transporting mining vehicles to overcome the problem that existing technologies cannot effectively manage the transportation process during cargo transfer, resulting in cargo loss during transportation and reduced management efficiency of mining vehicles.

[0007] To achieve the above objectives, the present invention provides an intelligent management system based on weighing and transportation of mining vehicles, comprising:

[0008] A weighing module used to weigh vehicles;

[0009] A vehicle-mounted module installed on the vehicle to monitor its status;

[0010] The central control console used for vehicle dispatching;

[0011] A ground module buried in the channel to monitor the channel status;

[0012] The on-board module is also used to detect and record the vibration process during the transportation route;

[0013] The central control console responds to the vibration process and sets the attribute of the corresponding channel as either a fatigue channel or a healthy channel.

[0014] The ground module responds to the setting of the fatigue channel, records the road surface wear degree of the fatigue channel, and resets the attributes of the corresponding channel;

[0015] In response to the setting of the channel attributes, the central control console performs load change processing or frequency change processing on the weighing module;

[0016] The central control console responds to changes in the fatigue channel and the health channel to determine the self-healing performance of each channel;

[0017] The weighing module determines the load and release of each vehicle based on the self-healing performance.

[0018] Furthermore, the vehicle-mounted module is equipped with a vibration detector and a path recorder.

[0019] The vibration detector is used to record the amplitude of the vehicle, and the path recorder is used to record the process of the vehicle traveling through the channel.

[0020] For a single transport, the vibration detector records the real-time vibration amplitude of the path recorder at any position on the transport channel, and forms the vibration process of that transport.

[0021] Furthermore, the ground module is also equipped with several wear detectors on the fatigue channel to mark the degree of road surface wear;

[0022] The wear detector is installed on the road surface of the passage;

[0023] The ground module collects data on the wear and tear of a single road surface at a preset interval.

[0024] The preset cycle is calculated based on the total transport weight of the road surface.

[0025] Furthermore, for a single channel, the central control unit is set with a maximum vibration trend corresponding to the channel. If the real-time vibration amplitude of two consecutive vehicles at the same position on the single channel is not less than the maximum vibration trend, the central control unit determines that the channel is the fatigue channel.

[0026] The maximum vibration trend is related to the vehicle's load and speed, and corresponds to the maximum value of the real-time vibration amplitude in that channel.

[0027] Furthermore, for a single channel, the central control unit is set with a maximum wear trend corresponding to the channel. If the change in the degree of road surface wear of the channel is not greater than the maximum wear trend in two consecutive cycles, the central control unit determines that the channel is a healthy channel.

[0028] The maximum wear trend is related to the road surface material and the vehicle's load.

[0029] Furthermore, in response to the determination of the health channel, the central control unit determines that the weighing module maintains the release strategy;

[0030] In response to the determination of the fatigue channel, the central control console determines whether the weighing module performs the load change process or the frequency conversion process;

[0031] The release strategy includes the vehicle's load and the vehicle's departure interval.

[0032] Furthermore, for a single channel, the center console is equipped with a standard vibration interval corresponding to the channel. If no fewer than two consecutive vehicles experience the same vibration within the standard interval, the center console determines that the channel is the fatigue channel.

[0033] The standard interval is the distance along the transportation route.

[0034] Furthermore, the weighing module is equipped with a weighing scale and a fence for weighing vehicles and for controlling the departure time of vehicles that meet the weighing standard using the fence.

[0035] The weighing module is equipped with a weight change gradient. When the variable load processing is performed, the response channel attribute is the fatigue channel, and the weighing module reduces the weight change gradient by one.

[0036] During the frequency conversion process, the weighing module adjusts accordingly based on the duration of the vehicle passing through the corresponding channel.

[0037] Furthermore, the central control console is equipped with a minimum efficiency cycle. For a single channel, if the minimum efficiency cycles are all healthy channels, the central control console performs load change processing or frequency change processing on the weighing module to improve the conveying efficiency of the channel.

[0038] In improving transport efficiency, the weighing module increases the weight change gradient and / or reduces the departure interval.

[0039] Furthermore, for a single channel, the central control console monitors the number of preset cycles corresponding to the change of its channel attributes from a fatigue channel to a healthy channel and records this as the self-healing performance.

[0040] The central control panel is also equipped with a maximum fatigue cycle and a limit vibration amplitude.

[0041] If the channel's attribute is set to fatigue channel throughout the consecutive maximum fatigue cycles, the central control console determines that the channel is damaged.

[0042] If the channel experiences at least one extreme vibration amplitude during the travel of two consecutive vehicles, the central control unit determines that the channel is damaged.

[0043] If any wear detector in the channel is damaged, the central control unit determines that the channel is damaged;

[0044] In response to the channel malfunction, the weighing module stops allowing vehicles to pass.

[0045] Compared with the prior art, the beneficial effects of the present invention are that it uses a weighing module to schedule vehicle departure and load, detects the passage based on the onboard module and the ground module, and uses the central control console to integrate the detection results to schedule vehicle load and departure frequency. This effectively avoids the problem of passage damage caused by load or departure frequency issues, which in turn affects transportation efficiency. At the same time, it uses the method of judging the self-healing ability of the passage to determine the bearing capacity of the passage, thereby effectively improving the transportation management efficiency of mining vehicles.

[0046] Furthermore, by determining the road surface wear and vehicle vibration conditions corresponding to a single passage, corresponding fatigue passages and healthy passages are marked, and the fatigue passages and healthy passages are periodically adjusted, thereby dynamically monitoring the actual load-bearing capacity of the corresponding passages in use, thus further improving the transportation management efficiency of mining vehicles.

[0047] Furthermore, by using a weighing module controlled according to the channel's attributes to weigh and release mining vehicles, the risks of cargo spillage or vehicle damage caused by channel problems are effectively avoided. At the same time, the channel itself can be repaired to a certain extent due to changes in the mining environment, thus saving on channel maintenance and effectively improving the efficiency of mining vehicle transportation management.

[0048] Furthermore, by monitoring vehicles and passageways, passageways that are about to require maintenance can be identified in a timely manner and repaired in advance. This not only effectively avoids long-term transportation disruptions caused by excessive damage to passageways, but also enhances the road's resilience to risks, thereby further improving the efficiency of transportation management for mining vehicles.

This is only for the convenience of description and is not intended to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0054] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0055] Please see Figure 1 As shown, it is a schematic diagram of the structure of the intelligent management system for weighing and transporting mining vehicles according to the present invention, including:

[0056] A weighing module used to weigh vehicles;

[0057] A vehicle-mounted module installed on the vehicle to monitor its status;

[0058] The central control console used for vehicle dispatching;

[0059] A ground module buried in the channel to monitor the channel status;

[0060] The on-board module is also used to detect and record vibration processes during transportation;

[0061] The central control panel responds to the vibration process and sets the attribute of the corresponding channel as either fatigue channel or healthy channel;

[0062] The ground module responds to the fatigue path settings, records the road surface wear level of the fatigue path, and resets the corresponding path attributes;

[0063] Based on the setting of the response channel attributes, the central control console performs load change processing or frequency conversion processing on the load shearing module;

[0064] The central control panel responds to changes in the fatigue channel and the health channel, and determines the self-healing performance of each channel;

[0065] The weighing module determines the load and release of each vehicle based on its self-healing properties;

[0066] Among them, self-healing performance refers to the corresponding ability of the channel to restore its carrying capacity after damage, which is related to the mine's climate, channel structure and road surface materials;

[0067] In road monitoring scenarios, carrying capacity refers to the maximum bearing capacity of the road surface structure to maintain its integrity under dynamic loads.

[0068] The system utilizes a weighing module to schedule vehicle departures and loads, monitors the passageways based on onboard and ground modules, and integrates the monitoring results at the central control station to schedule vehicle loads and departure frequencies. This effectively prevents passageway damage caused by load or departure frequency issues, thus avoiding disruptions to transportation efficiency. Furthermore, the system assesses the passageway's self-healing capabilities to determine its load-bearing capacity, thereby significantly improving the efficiency of mine vehicle transportation management.

[0069] In practice, because mine roads are mostly temporary access roads, their condition is affected by climate, surrounding environment, human factors, and the impact of construction vehicles, which can lead to a decrease or restoration of the road's carrying capacity. For example:

[0070] Scenario: Continuous rainfall in a mining area has caused localized softening of the road surface (gravel road), resulting in increased vehicle vibration.

[0071] Self-healing process:

[0072] Three days later, the weather cleared up, and the ground module detected a decrease in humidity, indicating that the wear and tear had stabilized.

[0073] The vibration data from the onboard module has returned to the normal range.

[0074] Scenario: Due to long-term heavy-load transportation, Channel 2 (clay subgrade) has developed deep ruts and structural damage.

[0075] Self-healing process:

[0076] After manual repairs, the ground module continued to monitor the system and found that the rut depth decreased by 2 cm per week.

[0077] Twenty days later, the wear data stabilized and the vibration test passed.

[0078] Scenario: Channel 3 (concrete road surface) has developed minor cracks due to vehicle overloading, but is not completely damaged.

[0079] Self-healing process:

[0080] Due to the self-shrinkage properties of concrete, cracks gradually close under low-frequency traffic.

[0081] Fifteen days later, the ground module test showed that the cracks had stabilized and the vibration data had returned to normal.

[0082] It can be determined that channel three has completed its self-healing process and the original scheduling strategy has been restored.

[0083] Scene: Passage 4 (old dirt road) has completely collapsed due to long-term overloading and rain erosion.

[0084] Self-healing performance analysis:

[0085] Based on historical data, the system determined that the self-healing cycle of the dirt road exceeded 60 days (far exceeding the threshold), and it needed to be completely rebuilt.

[0086] It is easy to understand that the above self-healing methods all correspond to the way a road can restore its carrying capacity. Based on these different types of self-healing situations, in actual operation:

[0087] Example 1:

[0088] Scenario: Due to long-term use, some sections of a transportation route in a mine have subsided.

[0089] The on-board module detected that multiple trucks were vibrating at the same location in lane X with amplitudes exceeding the preset threshold.

[0090] After analyzing the data, the central control console marks channel X as a fatigue channel and notifies the ground module to strengthen monitoring.

[0091] The wear detector on the ground module showed accelerated wear on this section of road, and the central control unit immediately adjusted its strategy:

[0092] Load adjustment: Limit the load of subsequent vehicles (e.g., reduce from 60 tons to 50 tons).

[0093] Frequency conversion processing: Extend the departure interval (e.g., from 5 minutes / vehicle to 8 minutes / vehicle).

[0094] One week later, the ground module detected that the wear trend had stabilized (returned to healthy standards), and the center console remarked channel X as a healthy channel and restored the standard load and departure frequency.

[0095] Self-healing performance assessment: The system records that due to the "asphalt + gravel" structure, the channel only needs 7 days to self-heal in dry climates, and can be prioritized for future scheduling.

[0096] Example 2:

[0097] Scenario: Heavy rain caused the roadbed of a mine access road (Y) to soften, drastically increasing the risk to vehicle traffic.

[0098] The vehicle module continuously reports that multiple vehicles experienced extreme vibrations (such as a sudden increase in amplitude of 300%) in a certain section of channel Y.

[0099] Based on data from the ground module (sensors detected road surface cracks), the central control console determined that channel Y was damaged and immediately initiated emergency measures:

[0100] The weighing module prohibits all vehicles from entering this lane.

[0101] The dispatching system automatically plans a detour through the health channel Z.

[0102] Self-healing performance analysis:

[0103] The roadbed is made of clay, and it takes 30 days to heal itself during the rainy season, which is far beyond the system threshold (15 days).

[0104] The central control panel triggered a maintenance alarm and prompted that "the roadbed needs to be manually reinforced."

[0105] After the repairs, the ground module confirmed that the road surface had been restored, the center console reassessed the self-healing performance (optimized to 20 days), and gradually opened the road to test vehicles.

[0106] Specifically, the vehicle-mounted module is equipped with a vibration detector and a path recorder.

[0107] Vibration detectors are used to record the amplitude of vehicle vibrations, and path recorders are used to record the process of vehicle travel along the route.

[0108] For a single transport, the vibration detector records the real-time vibration amplitude of the path recorder at any position on the transport channel, thus forming the vibration process of that transport.

[0109] Understandably, in practice, to quantify the vibration amplitude, the corresponding vibration can be represented by acceleration g (N / kg).

[0110] Based on Example 1:

[0111] Vibration detector: Truck A and Truck B were detected to have vibration amplitudes of 0.8g and 0.9g respectively at the same location in channel X (e.g., coordinate point P1) (preset threshold 0.7g).

[0112] Path recorder: Records the driving trajectories of truck A and truck B, and finds that the vibration exceeds the standard at point P1, forming a vibration process curve (e.g., P1: 0.8g, P2: 0.5g, P3: 0.6g).

[0113] Center console analysis: Vibration exceeded the standard in the same position of both vehicles, triggering fatigue detection.

[0114] Based on Example 2:

[0115] Vibration detector: Truck C was detected at position Q1 in channel Y with a vibration of 3.5g (normal value 1.0g, a sudden increase of 300%).

[0116] Path recorder: Recorded abnormal vibrations at position Q1 for trucks C, D, and E (Q1: 3.5g, Q2: 1.2g).

[0117] Central console analysis: Multiple vehicles experiencing extreme vibrations + ground cracking indicates damage to passageway Y, triggering emergency detour.

[0118] Specifically, the ground module also has several wear detectors installed on the fatigue path to mark the degree of road surface wear;

[0119] Among them, wear detectors are installed on the road surface of the passage;

[0120] The ground module collects data on the wear and tear of a single road surface at a preset interval.

[0121] The preset cycle is calculated based on the total transport weight of the road surface.

[0122] It is understandable that the wear sensor can be composed of:

[0123] Piezoelectric sensors: These monitor changes in electrical signals caused by vehicle pressure through embedded piezoelectric ceramics, suitable for assessing the bearing capacity of heavy-duty pavements; Fiber optic sensors: These use distributed fiber optic gratings to detect pavement cracks and structural deformation, suitable for long-distance, high-precision monitoring; Laser rangefinders: These identify pavement potholes and settlement through 3D scanning, used for automated inspection; Strain gauges / accelerometers: These measure the dynamic strain and vibration frequency of the roadbed, specifically designed for special pavements such as tracks / runways, etc. Any method that achieves the intended purpose of this solution is sufficient and will not be elaborated further.

[0124] Based on Example 1:

[0125] Wear detector: A sensor is installed at P1 of channel X to detect wear depth increasing from 5mm (cycle 1) to 8mm (cycle 2).

[0126] Collection cycle: Calculated based on total transport weight (e.g., once every 10,000 tons of ore), accelerated wear was observed.

[0127] Central control panel adjustments: load limit (60→50 tons), departure interval extended (5→8 minutes).

[0128] Based on Example 2:

[0129] Wear detector: After heavy rain, the wear depth at Q1 of channel Y increased sharply from 10mm to 25mm (single-cycle change).

[0130] Collection period: Due to the impact of heavy rain, the collection period was shortened (based on 5,000 tons of data) to confirm the softening of the roadbed.

[0131] The control panel responded: "Passage is prohibited; manual repair is required."

[0132] Specifically, for a single channel, the center console is set with the maximum vibration trend corresponding to the channel. If the real-time vibration amplitude of two consecutive vehicles at the same position on a single channel is not less than the maximum vibration trend, the center console determines that the channel is a fatigue channel.

[0133] The maximum vibration trend is related to the vehicle's load and speed, and corresponds to the maximum real-time vibration amplitude in that channel.

[0134] Based on Example 1:

[0135] Maximum vibration trend: Threshold 0.7g at a load of 60 tons and a speed of 30km / h.

[0136] Judgment logic: Truck A (0.8g) and Truck B (0.9g) continuously exceed the limit in P1, indicating fatigue channel.

[0137] Based on Example 2:

[0138] Maximum vibration trend: After heavy rain, the threshold for clay subgrade is adjusted to 2.0g (usually 1.0g).

[0139] Judgment logic: Trucks C (3.5g) and D (3.2g) exceeded the limit continuously, and damage was determined based on ground data.

[0140] Specifically, for a single lane, the central control panel is set with a maximum wear trend corresponding to the lane. If the change in the road surface wear degree of the lane is not greater than the maximum wear trend in two consecutive cycles, the central control panel determines that the lane is a healthy lane.

[0141] The greatest wear trend is related to the road surface material and the vehicle's load.

[0142] Based on Example 1:

[0143] Maximum wear trend: Asphalt pavement is allowed to increase wear by ≤1mm per week.

[0144] Judgment logic: After repair, the wear is only 0.5mm (≤1mm) one week later, and the healthy channel is restored.

[0145] Based on Example 2:

[0146] Maximum wear trend: Clay subgrade is allowed ≤2mm / week during the rainy season, but the actual measurement is 5mm / week, indicating that it cannot self-heal.

[0147] Post-repair optimization: After manual reinforcement, the wear trend decreased to 1mm / week, and it was reassessed as passable.

[0148] Specifically, in response to the confirmation of the health channel, the central control console determines that the weighing module should maintain the release strategy;

[0149] In response to the determination of the fatigue path, the central control console determines whether the weighing module should perform load change processing or frequency conversion processing;

[0150] The release strategy includes the vehicle's load and the vehicle's departure interval.

[0151] By determining the road surface wear and vehicle vibration conditions corresponding to a single passage, corresponding fatigue passages and healthy passages are marked, and the fatigue passages and healthy passages are periodically adjusted. This allows for dynamic monitoring of the actual load-bearing capacity of the corresponding passages during use, thereby further improving the transportation management efficiency of mining vehicles.

[0152] Based on Example 1:

[0153] Health channel strategy: Restore standard load (60 tons) and departure interval (5 minutes).

[0154] Fatigue path strategy: variable load (50 tons) + frequency conversion (8 minutes).

[0155] Based on Example 2:

[0156] Damaged lane strategy: The weighing module prohibits all vehicles from entering and dispatches them to detour lane Z.

[0157] Post-repair strategy: First release unloaded test vehicles (0 tons), then gradually increase to 30 tons and 50 tons.

[0158] Specifically, for a single channel, the center console is set with a standard vibration interval corresponding to the channel. If no fewer than two consecutive vehicles experience the same vibration within the standard interval, the center console determines that the channel is a fatigue channel.

[0159] The standard interval is the distance along the transportation route.

[0160] Based on Example 1:

[0161] Standard vibration interval set: 10 meters.

[0162] Test data:

[0163] Truck A vibrates at P1 (coordinate 0m) with a force of 0.8g (threshold 0.7g), and truck B vibrates at P1' (coordinate 10m) with a force of 0.9g.

[0164] Both vehicles exceeded the limit within a 10-meter interval, and lane X was determined to be a fatigue lane.

[0165] Based on Example 2:

[0166] Standard vibration interval set: 5 meters (monitoring accuracy will be reduced after heavy rain).

[0167] Test data:

[0168] Truck C vibrates at Q1 (0m) with a force of 3.5g, and truck D vibrates at Q1' (5m) with a force of 3.2g.

[0169] The two vehicles experienced extreme vibrations within a 5-meter interval. Based on the ground cracking data, it was determined that channel Y was damaged.

[0170] Specifically, the weighing module is equipped with a weighing scale and a fence to weigh the vehicle and to control the departure time of vehicles that meet the weight standard.

[0171] The weighing module has a weight change gradient. When performing variable load processing, the response channel attribute is fatigue channel, and the weighing module reduces the weight change gradient by one.

[0172] When performing frequency conversion processing, the weighing module adjusts accordingly based on the duration of the vehicle passing through the corresponding channel.

[0173] In implementation, a weight change gradient can be set, such as 10 tons per gradient (load capacity 60 tons → 50 tons → 40 tons → 30 tons → 20 tons → 10 tons).

[0174] Frequency conversion processing: Adjust the departure interval according to the vehicle's transit time (e.g., if the transit time is extended by 20%, the departure interval will increase by 20%).

[0175] Based on Example 1:

[0176] Original parameters: load capacity 60 tons (gradient 1), departure interval 5 minutes.

[0177] Fatigue channel response:

[0178] Variable load treatment: Reduce by one level to 50 tons (gradient 2).

[0179] Frequency conversion processing: Passing time increased from 10 minutes to 12 minutes → Departure interval adjusted from 5 minutes to 6 minutes.

[0180] Based on Example 2:

[0181] Damaged channel response:

[0182] The weighing module prohibits all vehicles from entering (gradient decreases to 0 tons).

[0183] Post-repair testing:

[0184] Empty vehicle (0 tons) transit time 15 minutes → departure interval 15 minutes (extreme frequency conversion).

[0185] The capacity will be gradually increased to 30 tons (gradient 1) and 50 tons (gradient 2), with the departure interval shortened accordingly.

[0186] Specifically, the central control console has a minimum efficiency cycle. For a single channel, if the minimum efficiency cycles are all healthy channels, the central control console performs load change processing or frequency change processing on the rebalancing module to improve the channel's transmission efficiency.

[0187] In improving transport efficiency, the weighing module increases the weight change gradient and / or reduces the departure interval.

[0188] By using a weighing module controlled according to the properties of the passageway to weigh and release mining vehicles, the risks of cargo spillage or vehicle damage caused by passageway problems are effectively avoided. At the same time, the passageway itself can be repaired to a certain extent due to changes brought about by the mining environment, thereby saving on passageway maintenance and thus effectively improving the efficiency of mining vehicle transportation management.

[0189] For example: minimum efficiency period: efficiency can be optimized if the patient is in a healthy state for 7 consecutive days.

[0190] Efficiency improvement measures: Add one weight gradient or shorten the departure interval.

[0191] Based on Example 1:

[0192] Health channel assessment: Wear trend ≤1mm / week for 7 consecutive days.

[0193] Efficiency improvement:

[0194] The load capacity increases from 50 tons to 60 tons (one grade increase).

[0195] The departure interval will be reduced from 8 minutes to 6 minutes (a reduction of 25%).

[0196] Based on Example 2:

[0197] Health channel assessment: Wear and tear stabilizes for 20 consecutive days after repair (the period is longer for clay subgrade).

[0198] Efficiency improvement:

[0199] The load capacity has been increased from 30 tons to 40 tons (gradient 1 to 2), and the departure interval has been reduced from 15 minutes to 12 minutes.

[0200] Note: Due to material limitations, efficiency has not been restored to pre-rainstorm levels.

[0201] Please see Figure 2 As shown, it is a schematic diagram of the operation of the intelligent management system of the present invention. For a single channel, the central control console monitors the number of preset cycles corresponding to the change of its channel attribute from fatigue channel to healthy channel and records it as the self-healing performance.

[0202] The center console also features a maximum fatigue cycle and a limit vibration amplitude.

[0203] If the channel's attribute is set to fatigue channel throughout the consecutive maximum fatigue cycles, the central control console determines that the channel is damaged.

[0204] If the channel experiences at least one extreme vibration amplitude during the driving of two consecutive vehicles, the center console determines that the channel is damaged.

[0205] If any wear detector in the channel is damaged, the central control panel determines that the channel is damaged;

[0206] The response channel is damaged, and the weighing module stops releasing the vehicle.

[0207] By monitoring vehicles and access roads, it is possible to identify access roads that are about to require maintenance in a timely manner and carry out repairs in advance. This not only effectively avoids long-term transportation disruptions caused by excessive damage to access roads, but also enhances the road's resilience to risks, thereby further improving the efficiency of transportation management for mining vehicles.
