DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4 A device for detecting and placing an unmanned container truck includes an unmanned container truck body 100 and eight detection mechanisms 200. Eight mounting brackets 101 are fixedly connected to the unmanned container truck body 100. The detection mechanisms 200 are arranged on the mounting brackets 101. The detection mechanisms 200 include a fixed base 7, on which a variable-area flat-plate capacitive sensor 5 is arranged.

[0019] The top of the fixed base 7 is fixedly connected to the pressure rod support frame 3, and the front of the pressure rod support frame 3 is provided with a sensor fixing frame 4. The side of the sensor fixing frame 4 close to the pressure rod support frame 3 is in contact with the pressure rod support frame 3, and the front of the sensor fixing frame 4 is provided with four fixing bolts 9 threadedly connected to the pressure rod support frame 3. The sensor fixing frame 4 is installed on the pressure rod support frame 3 through the fixing bolts 9. The variable area type flat plate capacitive sensor 5 is installed on the front of the sensor fixing frame 4. The rear end of the variable area type flat plate capacitive sensor 5 passes through the sensor fixing frame 4 and the pressure rod support frame 3 from front to back and extends to the inside of the pressure rod support frame 3. A rubber gasket 1 is provided above the pressure rod support frame 3, and the bottom of the rubber gasket 1 is fixedly connected to the pressure rod 2. The bottom end of the pressure rod 2 passes through the pressure rod support frame 3 and Extending into its interior, a cylindrical helical compression spring 8 is sleeved on the surface of the pressure rod 2 and located at the top of the pressure rod support frame 3, a variable area hole 6 is opened on the front of the pressure rod 2 and corresponding to the position of the strain area type flat capacitive sensor 5, and the four fixed bases 7 located on the rear side are provided with a first mounting hole 10, a second mounting hole 11, a third mounting hole 12 and a fourth mounting hole 13 from right to left, and the four fixed bases 7 located on the front side are provided with a fifth mounting hole 14, a sixth mounting hole 15, a seventh mounting hole 16 and an eighth mounting hole 17 from left to right, and the eight fixed bases 7 are respectively installed on the first mounting hole 10, the second mounting hole 11, the third mounting hole 12, the fourth mounting hole 13, the fifth mounting hole 14, the sixth mounting hole 15, the seventh mounting hole 16 and the eighth mounting hole 17.

[0020] The area-type flat-plate capacitive sensor 5 does not need to be in direct contact with the container, which reduces the damage to the area-type flat-plate capacitive sensor 5 caused by the impact when loading and unloading the container, and extends the service life of the area-type flat-plate capacitive sensor 5. The variable-area flat-plate capacitive sensor 5 has high precision and can monitor the weight of each container in real time, adjust the driving speed according to the total load, and has low cost and long service life. It can also realize real-time monitoring of the status of the container loading, and can promptly detect containers that are not placed normally, and transmit signals to the vehicle ECU, give an alarm for crooked boxes, reduce the vehicle speed, and adjust the parking position of offset boxes when parking, which is convenient for subsequent grasping processing.

[0021] Furthermore, the ECU is composed of large-scale integrated circuits such as a microprocessor, memory, input / output interface, and analog-to-digital converter, and its core is a microcomputer system with a single-chip microcomputer as the main body. The ECU is electrically connected to the area-type flat-plate capacitive sensor 5.

[0022] During use, by designing the shape of the variable-area hole 6 into a circular arch, when the pressure rod 2 is squeezed by the container, the pressure rod 2 presses the cylindrical helical compression spring 8 downward, and the pressure rod 2 drives the variable-area hole 6 to move downward. The greater the downward pressure from the container, the larger the area of ​​the area-type flat-plate capacitive sensor 5 covered by the variable-area hole 6, thereby converting the pressure into an electrical signal and transmitting it to the vehicle ECU. The vehicle determines the container loading status based on the signals provided by the eight area-type flat-plate capacitive sensors 5;

[0023] When the container is placed on the unmanned container truck body 100 and comes into contact with the pressure bar 2, the vehicle controller receives a detection command. The vehicle controller determines whether the containers are consistent based on the information obtained from the area-type flat-plate capacitive sensors 5 on the first mounting hole 10, the second mounting hole 11, the third mounting hole 12 and the fourth mounting hole 13, as well as the container mission information. When the detection result is normal, the vehicle controller determines whether the containers are consistent based on the information obtained from the area-type flat-plate capacitive sensors 5 on the fifth mounting hole 14, the sixth mounting hole 15, the seventh mounting hole 16 and the eighth mounting hole 17, as well as the container mission information. When the detection results are all normal, the vehicle starts to transport according to the set trajectory and speed.
