No human intervention is required in the middle, the degree of automation is high, and it is conducive to improving work efficiency.
[0012] The automatic vehicle moving method underground is used for an operating machine. The operating machine has a rotation center and a front face and a rear face that are relatively arranged. Optionally, the operating machine includes a fuselage, a cutting part and a shovel board part. The shovel board part and the cutting part are arranged at the same end of the fuselage, and the cutting part is located above the shovel board part. The cutting part is used to fracture and cut the rock mass, after which the block materials fall, and the shovel board part is used to stack and collect the block materials that fall on the ground or directly fall on the shovel board part. Optionally, the rotation center is the geometric center of the fuselage. The rear face of the operating machine is an end face of the fuselage away from the cutting part and the shovel board part. The front face of the operating machine is an end face of the shovel board part away from the fuselage. Further, the front face has a first side edge and a second side edge that are relatively arranged. Optionally, the first side and the second side are two side edges of the shovel plate away from the body. Since the width of the shovel plate is usually greater than the width of the body, the positions of the two side edges of the shovel plate need to be considered when studying whether the working machine will collide with the side wall of the tunnel during rotation. Further, the tunnel has a first side wall and a second side wall that are arranged oppositely. Of the first side and the second side, the first side is closer to the first side wall, and the second side is closer to the second side wall. Optionally, the working machine is a tunneling machine, and of course it can also be other types of equipment.
[0013] The specific steps of the underground automatic vehicle moving method include:
[0014] In the first step, when the operating machine moves from the first position to the second position in the tunnel, the first distance, the second distance and the first angle are determined, wherein the first distance is the distance between the center of rotation and the first side wall, the second distance is the distance between the center of rotation and the first side edge, the first angle is the angle between the first plane and the second plane, the first plane is the plane passing through the center of rotation and the first side edge, the second plane is the plane symmetrical to the first side edge and the second side edge and the second plane passes through the center of rotation.

Optionally, the positioning component includes a wire displacement sensor and a gyroscope angle sensor. The second distance and the first angle are design parameters of the operating machine. The plane passing through the center of rotation and the first side edge is the first plane. The first side edge and the second side edge are symmetrical about the second plane, and the center of rotation is on the second plane.

[0016] The third step is to determine the moving path of the operating machine from the first position to the second position based on the first distance and the first current maximum rotatable angle. In the process of the operating machine moving from the first position to the second position, if the distance (first distance) between the center of rotation and the first side wall changes, the first current maximum rotatable angle will also change continuously, so as to realize automatic planning of the moving path and automatic lateral movement. Optionally, after the movement is completed, the positioning component determines the actual lateral displacement of the movement, and the inertial navigation system calculates the coordinate offset of the cutting part on the working surface, and continues the unmanned operation to cut the other half of the surface, so as to realize the unmanned operation of the complete working surface.

[0020] In this technical solution, before determining the moving path of the working machine, the steps of the underground automatic vehicle moving method also include:
[0021] During the process of the operating machinery rotating with the center of rotation as the origin, the position of the operating machinery in the tunnel is determined, and a first compensation amount is determined to correct the first distance. The underground automatic vehicle moving of the operating machinery relies on a combination of an inertial navigation system and a wire-drawing displacement sensor to determine the position change of the operating machinery in the tunnel. Optionally, the wire-drawing displacement sensor is arranged at the center of rotation of the operating machinery to more accurately obtain the distance between the center of rotation and the side wall of the tunnel. The orientation of the wire-drawing displacement sensor will change during the process of the operating machinery rotating with the center of rotation as the origin. The influence of the orientation change of the operating machinery on the wire-drawing displacement sensor can be eliminated by the following formula, , , Optionally, the inertial navigation system is used to obtain the polar coordinates P (r, , ).

Optionally, the controller determines the distance (third distance) between the rotation center and the second side wall through the positioning component.

[0026] The moving path of the working machine from the second position to the third position is determined according to the third distance and the second current maximum rotatable angle. In the process of the working machine moving from the second position to the third position, if the distance (third distance) between the rotation center and the second side wall changes, the second current maximum rotatable angle will also change continuously, thereby realizing automatic planning of the moving path and automatic lateral movement.
[0027] In some technical solutions, optionally, before determining the moving path of the working machine from the second position to the third position based on the third distance and the second current maximum rotatable angle, the underground automatic vehicle moving method also includes: during the rotation of the working machine with the rotation center as the origin, determining the position of the working machine in the tunnel, and determining the second compensation amount to correct the third distance.

The underground automatic moving of the operating machine relies on the combination of an inertial navigation system and a wire displacement sensor to determine the position change of the operating machine in the tunnel. Optionally, the wire displacement sensor is arranged at the center of rotation of the operating machine to more accurately obtain the distance between the center of rotation and the side wall of the tunnel. By continuously correcting the third distance, a more accurate second current maximum rotatable angle can be calculated.
