[0003] Traditional asphalt slope paving truck feeding systems suffer from numerous technical bottlenecks: pre-construction equipment debugging relies on manual labor, resulting in low efficiency and susceptibility to errors; poor coordination between mixture transportation and transfer often leads to "waiting for material and stopping the machine," disrupting construction continuity; lack of precise means for mixture temperature control results in rapid heat loss, easily causing quality defects such as compaction difficulties and segregation; feeding equipment often uses single-rope traction, which is prone to swaying and tilting under uneven force on slopes, and lacks effective emergency protection in case of wire rope breakage, posing a high safety risk; the connection between the feeding equipment and paving equipment relies on manual coordination, easily leading to problems such as excessive material supply causing overflow or insufficient material supply interrupting paving; paving equipment is prone to deviation due to uneven gravity and resistance, and traditional anti-deviation solutions are slow to respond and have low accuracy; each piece of equipment operates independently, resulting in poor system coordination and untimely action coordination; construction parameters are difficult to monitor in real time, and quality control relies on post-construction testing, making process control and traceability impossible.

[0019] Among them, the intelligent system construction and parameter preset unit of the construction preparation module includes preset parameters such as the optimal construction temperature range of the mixture (140℃-160℃), the full threshold of the transfer silo (75% of the silo volume), the replenishment threshold (18.75% of the silo volume), the single unloading volume setting value, the double rope traction tension difference threshold ≤5%, the paver travel deviation threshold ≤3mm / m, the paving speed (2-4m / min), the paving thickness error ≤±3mm, the hopper fullness threshold (80%), and the replenishment threshold (30%). These parameters can be modified through the human-machine interface or remote terminal. Among them, in the equipment and system joint self-inspection unit of the construction preparation module, when the system self-inspection fails, a detailed fault report is generated, the operation mode is locked, and the fault is eliminated and the self-inspection is passed again. The closed-loop control response time is ≤0.5 seconds. Among them, the mixed material buffer coordination unit of the transfer metering temperature control module has a transfer silo buffer capacity that can store 2-3 truckloads of mixed material, effectively reducing the time difference in transportation connection and eliminating "stopping the machine while waiting for materials"; In the traction emergency support unit of the precision feeding and conveying module, the system response time is ≤0.3 seconds when a single rope breaks. Through the linkage mechanism of releasing the connection structure on the broken side and pushing the elastic component on the intact side to reset, it is ensured that the point of application of traction force coincides with the geometric center of gravity of the equipment. In the smooth transfer control unit of the mixture transfer and paving module, the opening rate of the unloading gate of the feeding equipment can be adjusted according to the characteristics of the mixture, ranging from 5° to 15° / s, to ensure that the mixture falls evenly into the hopper of the paving equipment. Among them, in the hopper fullness monitoring unit of the mixed material transfer and paving module, the liquid level sensor has a detection accuracy of ≤±5mm, and provides real-time feedback of hopper material level data to ensure the balance of supply and demand in the transfer. Among them, the real-time correction adjustment unit of the anti-deviation module for paving operations has a correction response time of ≤0.8 seconds, ensuring that the paving equipment can quickly return to the preset travel trajectory and improve the paving smoothness; Among them, the data storage and traceability unit of the intelligent monitoring and control module records information such as construction location, process parameters, transmission data, and equipment status in the electronic construction log, which can accurately link quality problems with the construction process; When using it, the following steps are included: A. 1-2 hours before operation: Mark the paving track on the slope according to the construction design drawings (parallelism error ≤ ±1mm), level the transportation channel and equipment operation area, remove obstacles, plan the optimal route for transporting the mixture and the area for coordinated operation of the feeding and paving equipment; fix the transfer hopper and ensure that the support is firm, install the double rope traction feeding equipment guide rail (extending to the top of the paving equipment hopper), assemble the paving equipment and install the liquid level sensor in the hopper, conduct no-load tests on the actuators such as the drive cylinder and balance cylinder, and adjust the flexibility of the feeding equipment unloading gate. B. 1-2 hours before operation: Start the central control system, establish signal connection between the actuators and detection elements, and preset process parameters (optimal temperature of the mixture 140℃-160℃, full hopper threshold 75% / replenishment threshold 18.75%, double rope traction tension difference threshold ≤5%, paving speed 2-4m / min, hopper full threshold 80% / replenishment threshold 30%, etc., parameters can be adjusted through the human-machine interface); the system automatically detects the actuators, calibrates the detection elements, and verifies the signal link. If the self-test is qualified, it displays "ready"; if it fails, it generates a fault report. After troubleshooting, the self-test is repeated. C. 30 minutes before operation: Mix the asphalt mixture according to the preset mix ratio (mixing time 45-60 seconds), check the temperature (150℃-170℃) and viscosity of the mixture, and load it on the truck only after it meets the standards; the transport vehicle should use a double-layer rock wool insulated compartment, and monitor the temperature inside the compartment in real time (temperature loss during transportation ≤5℃ / h), and the system will issue an early warning when the temperature is abnormal. D. 30 minutes before operation to the entire operation: The central control system dynamically schedules the departure time and route of transport vehicles based on the real-time inventory of the transfer silo. When the inventory of the transfer silo approaches the replenishment threshold, it automatically sends a replenishment command. It monitors the vehicle position through GPS positioning and automatically plans alternative routes in case of congestion. E. After the operation begins (full cycle): After the transport vehicle arrives, the operator sends the unloading command, and the system controls the vehicle to unload to the transfer silo (buffer capacity of 2-3 truckloads of material); the weighing sensor collects the total weight in real time and automatically deducts the weight of the silo itself, calculates the actual inventory and displays it in real time. When the full silo threshold is reached, the vehicle is instructed to stop unloading and a prompt is given. When the inventory drops to the replenishment threshold, a replenishment alarm is issued and the dispatcher is notified. F. After the operation begins (full cycle): The temperature sensor collects the temperature of the mixture in the silo in real time. When the temperature is below 140℃, the cast aluminum electric heating plate is automatically started and stopped when the temperature reaches 160℃. The temperature is stabilized by the double protection of rock wool insulation layer and heating plate. G. After the operation begins (full cycle): Based on the displacement sensor data, the system instructs the feeding device to move precisely along the guide rail to below the discharge port of the transfer hopper (positioning accuracy ≤ ±5mm); controls the drive cylinder to open the discharge port, and the mixed material falls into the feeding device hopper. The weighing sensor monitors the unloading amount in real time. When the preset single unloading amount is reached, the system instructs the cylinder to close the discharge port (unloading accuracy error ≤ ±2%). H. After the operation begins (full cycle): The system starts the double-rope winch to synchronously wind up and unwind the traction rope. The tension sensor monitors the tension difference, and when it exceeds 5%, the winch speed is automatically adjusted to balance the tension. If a single rope breaks, the system responds within 0.3 seconds. The T-shaped slider on the broken side is discharged through the discharge hole, and the spring on the intact side pushes the corresponding slider to the center of the equipment to maintain balance. At the same time, an emergency alarm is issued. The operator can remotely control the feeding equipment to correct the direction and open and close the door. I. After the operation begins (full cycle): The system synchronizes the position data of the feeding and paving equipment in real time, plans the optimal transfer path (equipment spacing ≥ 0.5m), and dynamically adjusts the transfer speed according to the paving speed; when the feeding equipment moves above the hopper of the paving equipment, the system adjusts the opening rate of the unloading gate (5°-15° / s) according to the characteristics of the mixture, and monitors the transfer volume in real time through the weighing sensor of the feeding equipment; J. After the operation begins (full cycle): The liquid level sensor in the hopper of the paving equipment (detection accuracy ≤ ±5mm) provides real-time feedback of the material level data, which is dynamically displayed by the system; when the material level reaches 80% of the full threshold, the feeding equipment is instructed to stop unloading and return to loading; when it drops to 30% of the replenishment threshold, the transfer is started to achieve "full stop empty replenishment". K. After the operation begins (full cycle): The system sets parameters such as paving speed and paving thickness, starts the paving travel motor, and drives the double winches synchronously through the reducer to move the paving equipment; the encoder collects the speed and displacement data of the traction ropes on both sides in real time. When the deviation exceeds 3mm / m, the corresponding side balance cylinder is immediately commanded to extend and retract to correct the deviation (response time ≤0.8 seconds); when it is necessary to pause, the motor is commanded to stop running and the braking device is activated to lock the winch drum. After completing one section of paving, the next cycle begins. L. After the operation begins (full cycle): The system summarizes key data such as temperature, materials, equipment operation, transfer, and paving, compares them with preset values, and then issues tiered alarms (Level 1 anomalies trigger audible and visual alarms + emergency response + mobile phone push notifications; Level 2 anomalies issue a warning signal); Data is stored using both cloud and local backups, and electronic construction logs are automatically generated; Management personnel can remotely monitor through the cloud platform, and the system automatically fine-tunes construction parameters based on data trend analysis; M. After the operation is completed: The system commands clear the remaining mixture in the empty transfer hopper, feeding equipment and paving equipment, clean the parts of the equipment that come into contact with the material, and add lubricating oil to the rotating parts for maintenance; test the thickness, flatness and compaction of the paved surface according to the specifications, and generate a quality acceptance report by linking the system data; the system automatically generates a construction summary report (including information such as total construction volume and material consumption); shut down the equipment power and system in sequence, and archive the relevant reports and logs.
