[0013] Specifically, the laser radars are provided in two numbers, and the two laser radars are respectively provided on both sides of the loading channel; the measurement data complement each other, one for work and one for backup.

[0014] A method for using an automatic loading system capable of switching aggregate types, comprising the following specific steps:

[0015] Step 1: The central control room sends control instructions to the control cabinet of the loading system through the host computer based on the type of material to be loaded. The control cabinet controls the double-layer rod valve and electric fan valve under the required material pile to open, and the material flow is released onto the feeding belt. The material is then transported to the distribution belt via the feeding belt. When switching the type of aggregate, the material flow detector is used to detect whether the material on the feeding belt is empty, and the video monitoring system is used to confirm that the material on the distribution belt is empty. When there is material, the material flow detector will send a pressure signal to the host computer. When there is no material, there will be no pressure signal or the signal will be very small.

[0016] Step 2: The green light at the entrance of the truck scale is on, and the vehicle enters the loading channel. The light barriers on both sides of the truck scale check whether the vehicle has completely entered the truck scale. If the two light barriers detect that the vehicle has completely entered, the truck scale will weigh the vehicle's tare weight, and the LED screen will display the weight information. The driver waits for loading. The license plate recognition integrated machine recognizes the license plate number and verifies the system's reservation registration information. If the vehicle has not completely entered, the bell will ring, prompting the driver to drive the vehicle completely onto the truck scale. If the reservation registration information is incorrect, the driver will be prompted to get off the truck scale.

[0017] Step 3: The laser radar scans the vehicle, reads the length, width, height, and position information of the vehicle compartment and the front and rear tailgates, and sends it to the host computer. The host computer determines the position of the truck bed based on the vehicle position information and sends instructions to the control cabinet to control the movement of the fabric belt, forming a closed-loop position control.

[0018] Step 4: The fabric trolley moves to the loading starting point on the fabric belt and starts loading. The driver is prompted by an audio system to start loading. The fabric trolley moves from front to back and loads slowly. When the rear of the carriage is full, the fabric belt stops. The audio system prompts the driver that loading is complete. The LED screen displays the gross weight information. The truck scale is measured and transmits the signal to the host computer through the control cabinet. The host computer sends a command to the control box. The control box controls the exit section traffic light to turn green, the barrier lifts, and the driver drives the vehicle out of the loading channel. The camera monitors the entire loading process and records it. The central control room can remotely watch the loading process and remotely operate. In special circumstances, the equipment can be shut down at any time, the operation can be stopped, and the driver can be called through the audio system.

[0019] Due to the adoption of the above technical solution, the present invention has the following advantages:

[0020] The automatic loading system capable of switching aggregate types and the use method thereof of the present invention can realize multiple operation modes including on-site, central control and fully automatic. The automatic switching of aggregate types has a wide range of applications, does not require the driver to move the vehicle, improves loading and shipping efficiency, and has a good market prospect.
