[0027] For example, a weighbridge 1 is provided in the area where the truck is loaded with aggregates. After the truck drives onto the weighbridge 1 and is ready to be loaded, the slide rail 2 may include an electric slide rail 2 on the top and a bracket connected to the ground. The electric slide rail 2 may be an existing electric slide rail 2 and is controlled by a controller 7. The electric slide rail 2 is above the weighbridge 1 and has a certain height from the weighbridge 1 to facilitate the entry of the truck. The discharge port 3 provided on the slide rail 2 can slide left and right on the slide rail 2, and the discharge port 3 can be raised and lowered by the controller 7. The discharge port 3 is cylindrical and is used to fill the truck with aggregates. The material level switch 9 provided in the discharge port 3 transmits a signal to the controller 7. When the filled aggregates are When the material reaches a certain height, the material level switch 9 can be triggered and transmit the signal to the controller 7. The laser scanner 4 can be a 3D laser scanner 4, which is set on the bracket of the slide rail 2, located above the truck and facing the direction of the truck. It is used to scan the truck and transmit the information to the server 8 through the switch 6. The switch 6 and the server 8 can be commonly used on the market. The controller 7 can be a programmable logic controller PLC. The switch 6 can be set next to the floor scale 1. The server 8 and the control are set in the control center where the staff are located. The sensor component 5 can be used to identify the relative position of the discharge port 3 to ensure that the discharge port 3 can It can align the position of the truck compartment. After the truck drives onto the weighbridge 1, the 3D laser scanner 4 automatically scans the truck and connects to the server 8 through the switch 6. The coordinate data is transmitted to the server 8 via Ethernet. The server 8 performs 3D modeling of the truck compartment based on the data and can obtain basic data information such as the length, width and baffle height of the truck compartment. Then the controller 7 controls the slide rail 2 to move the discharge port 3 to the top of the truck compartment, and then controls the discharge port 3 to descend, and then controls the discharge port 3 to open and fill the aggregate. When the aggregate filled in the discharge port 3 reaches the specified height, the material level switch 9 is triggered, and the controller 7 closes the discharge port 3. The discharge port 3 is controlled to be lifted to the specified position, and then the server 8 controls the discharge port 3 to move to the next position through the 3D modeling of the truck compartment. After the truck is filled with aggregates many times, the controller 7 controls the discharge port 3 to be closed and return to its original position. The whole process is coordinated and cooperated by the system, with less staff participation and low labor costs, which greatly saves labor costs. The system can accurately complete the filling of aggregates in the truck compartment, and there is no need for staff to set and check the aggregates filled in the truck. The work intensity of the staff is low, the overall aggregate loading process is simple, and the efficiency of aggregate loading is effectively improved.

[0028] Furthermore, a first grating 10 and a second grating 11 are spaced apart on the side of the scale 1 , and both the first grating 10 and the second grating 11 are connected to the controller 7 by signal.

[0029] In a possible embodiment, the first grating 10 and the second grating 11 each include two gratings. The two gratings of the first grating 10 are spaced apart and arranged on the side of the scale 1 and close to the scale 1. The distance between them is greater than the width of the truck, which is convenient for the truck to pass through. The two gratings of the second grating 11 are spaced apart and arranged on the side of the first grating 10. The distance between them is also greater than the width of the truck. There is also a distance between the two gratings of the first grating 10 and the two gratings of the second grating 11. When the truck drives onto the scale 1, the tailgate of the truck is located between the first grating 10 and the second grating 11, blocking the first grating 10 while not blocking the second grating 11. The controller 7 can know that the truck has stopped in place through the signals transmitted by the first grating 10 and the second grating 11, which is convenient for controlling the next step of aggregate filling.

[0030] Furthermore, the sensor assembly 5 includes a pull-wire sensor 501, an ultrasonic sensor 502 and an inclination sensor 503. The pull-wire sensor 501 is arranged on the discharge port 3. The ultrasonic sensor 502 is arranged on the discharge port 3 and the second grating 11. The inclination sensor 503 is arranged on the discharge port 3. The pull-wire sensor 501, the ultrasonic sensor 502 and the inclination sensor 503 are all connected to the controller 7 signal.

[0031] The pull-wire sensor 501 arranged on the side of the discharge port 3 can transmit a signal to the controller 7. The controller 7 can judge the height of the discharge port 3 by the signal information transmitted by the pull-wire sensor 501, and control the discharge port 3 to drop to the system specified height through the pull-wire switch. There are two sets of ultrasonic sensors 502, one of which is installed on the nose of the discharge port 3. The controller 7 locates the position of the discharge port 3 through the ultrasonic sensor 502 and controls the discharge port 3 to run to the first discharge position. The ultrasonic sensor 502 is also used to locate the discharge port 3 and the material loaded onto the truck. The distance between the piles is determined and the signal is transmitted to the controller 7, so that the controller 7 stops filling after the filled aggregate reaches the specified height. Another set of slide rails 2 is installed above the second grating 11, which is used to locate the distance between the discharge port 3 and the tail plate of the truck and transmit the information to the controller 7, so that the controller 7 can control the discharge port 3 to repeatedly fill the aggregate to fill the entire truck compartment.

The camera 12 can monitor the situation of the truck and upload the monitored image to the display screen 13 at the control center in real time through the switch 6. The display screen 13 can be an LED display screen 13. The staff can conveniently observe the situation of multiple trucks filling aggregates through the display screen 13 without the need for close observation, which can effectively save labor costs. When the signals transmitted by the first grating 10 and the second grating 11 are abnormal, that is, the truck is not parked in place, the staff can also observe it through the display screen 13, which is convenient for reminding the driver.

[0034] Furthermore, a traffic light 14 and a voice player 15 are provided on the side of the weighing scale 1. The traffic light 14 is located above the voice player 15. The traffic light 14 is connected to the controller 7 signal, and the voice player 15 is connected to the switch 6 signal.

[0035] In one possible embodiment, a traffic light 14 is provided on the side of the weighing scale 1 and in front of the truck. When the truck is filling aggregate, the controller 7 controls the traffic light 14 to be in a red light state. When the truck has finished filling the aggregate, the controller 7 controls the discharge port 3 to be closed and return to its original position, and then the controller 7 controls the traffic light 14 to be in a green light state to remind the truck driver that the aggregate filling is completed. Since some truck drivers are not focused and cannot drive the truck out in time, a voice player 15 installed under the traffic light 14 can be used to remind them. The switch can enable the voice player 15 to emit a sound of "Loading is completed, please drive out the vehicle in time", which can better remind the driver. When the signal transmitted by the first grating 10 and the second grating 11 is abnormal, that is, the truck is not parked in place, the voice player 15 can also emit a sound to remind the driver.

[0036] Furthermore, a barrier gate 16 is provided on the side of the second grating 11 , and the barrier gate 16 is connected to the controller 7 via signals.

[0037] In one possible embodiment, a gate 16 is provided on the side of the second grating 11 and away from the weighing scale 1. When a truck needs to drive onto the weighing scale 1, the controller 7 controls the gate 16 to open to facilitate the entry of the truck. After the truck enters and is ready to start filling aggregate, the controller 7 controls the gate 16 to close to avoid the impact caused by the entry of the truck behind.

[0038] Furthermore, a card reader 17 is provided on the side of the gate 16 , and the card reader 17 is signal-connected to the switch 6 .

[0039] In one possible embodiment, a card reader 17 is provided on the side of the barrier 16 and away from the second grating 11. The card reader 17 can be a card swiping and code scanning card reader 17. The truck driver is equipped with a card. After the truck driver drives the truck onto the scale 1 and stops at the designated position, he gets off the truck and swipes the card at the card reader 17, and uploads it to the system through the switch 6. The system verifies the card information. After the verification is successful, the 3D laser scanner 4 starts to scan the truck compartment and transmits the data coordinates to the server 8.
