Patent Description:
With the development of science and technology, the field of agricultural machinery has developed rapidly, especially the harvester. More and more harvesters are being developed in the intelligence and autonomous direction, which frees people from heavy agricultural labor. At the same time, the efficiency of agricultural production is effectively improved.

Traditional harvesters usually require a driver to drive when performing agricultural operations, and the harvester driver controls the movement and operation of the harvester. During the operation of traditional harvesters, when an emergency occurs, the driver of the harvester can control the harvester to stop moving to prevent injury to the human body or property damage. In other words, the safety performance of the traditional harvester can be relatively adequately guaranteed.

Since the unmanned harvester does not involve the driver during the operation of the harvester, when the harvester encounters an emergency situation, for example, when the signal between the unmanned harvester and the remote control system is interrupted, the unmanned harvester will be out of control. At this time, if emergency braking measures cannot step in to take control of the unmanned harvester to stop it from moving, the unmanned harvester could become a great threat to human and property safety to those near it. Documents <CIT>, <CIT>, and <CIT> disclose known agricultural machines with breaking functions.

With the progress of society and the development of technology, the unmanned harvester has become an inevitable development trend. However, how to solve the huge safety hazard that exists in the signal interruption between the unmanned harvester and the remote control system during the operation of the unmanned harvester has become an urgent technical problem to be solved in the development of the unmanned harvester.

When the communication detection system <NUM> detects the communication between the wireless communication assembly <NUM> arranged in the harvester body <NUM> and the remote control system <NUM> fails, the braking system <NUM> takes emergency braking measures to control the braking of the harvester body <NUM>, thereby preventing the harvester body <NUM> from continuing to move without the control of the remote control system <NUM>. and protecting people's lives and property safety.

In at least one embodiment, the intelligent harvester with automatic braking function may further include a transmission assembly <NUM> arranged in the harvester body <NUM>. The operating state of the harvester body <NUM> can be controlled by controlling the transmission assembly <NUM> to switch between different states. For example, when the transmission assembly <NUM> is switched to a walking gear, the harvester body <NUM> can be driven to move forward, when the transmission assembly <NUM> is switched to a reverse gear, the harvester body <NUM> can be driven to move backward, and when the transmission assembly <NUM> is switched to a neutral position, the harvester body <NUM> can stop moving.

The transmission assembly <NUM> is operatively connected to the braking system <NUM>. When the communication detection system <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the braking system <NUM> can control the operation of the transmission assembly <NUM> and adjust a working state of the transmission assembly <NUM> to stop the movement of the harvester body <NUM>. Specifically, when the communication detection system <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the braking system <NUM> drives the HST to switch to the neutral position to stop the movement of the harvester body <NUM>.

Referring to <FIG>. specifically, when the communication detection system <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the communication detection system <NUM> generates a detection information <NUM>.

The first driving assembly <NUM> is connected to the transmission assembly <NUM>, and can drive the transmission assembly <NUM> to switch between different working gears. When the communication detection system <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the controller <NUM> can obtain detection information <NUM> from the communication detection system <NUM>, and control the first driving assembly <NUM> to drive the transmission assembly <NUM> to switch to the neutral position based on the detection information <NUM>, thereby stopping the movement of the harvester body <NUM>. So that the harvester body <NUM> is prevented from continuing to move in an out of control state to avoid losses to people's lives and property.

Preferably, referring to <FIG>, the first driving assembly <NUM> may be a driving motor <NUM>. The driving motor <NUM> is connected to the HST. The driving motor <NUM> can drive the HST to switch between different gear states. When the communication detection system <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the driving motor <NUM> drives the HST to switch to the neutral position to stop the movement of the harvester body <NUM>.

The driving motor <NUM> may include a motor main body <NUM> and a driving shaft <NUM> extending outward from the motor main body <NUM>. The motor main body <NUM> can drive the driving shaft <NUM> to rotate. The transmission assembly <NUM> may include a transmission main body <NUM> and a control rod <NUM> extending outward from the transmission main body <NUM>. The control rod <NUM> can be driven to make a piston movement relative to the transmission main body <NUM>. When the control rod <NUM> is driven to make the piston movement relative to the transmission main body <NUM>, a transmission ratio of the transmission main body <NUM> can be changed, thereby changing the gear of the harvester body <NUM>.

The driving shaft <NUM> of the first driving assembly <NUM> is connected to the control rod <NUM> of the transmission assembly <NUM>. When the driving shaft <NUM> of the first driving assembly <NUM> rotates, the control rod <NUM> of the transmission assembly <NUM> is driven by the driving shaft <NUM> to make a piston movement relative to the transmission main body <NUM>, thereby controlling the transmission assembly <NUM> to switch between different gear states.

Preferably, the driving shaft <NUM> of the driving motor <NUM> is perpendicular to the control rod <NUM> of the transmission assembly <NUM>, and is engaged with the control rod <NUM> of the transmission assembly <NUM>. When the driving shaft <NUM> rotates, the control rod <NUM> is driven to make a piston movement relative to the transmission main body <NUM>.

The transmission assembly <NUM> may further include a second gear assembly <NUM> arranged on the control rod <NUM>. The first gear assembly <NUM> is adapted to the second gear assembly <NUM>. The first gear assembly <NUM> is meshed with the second gear assembly <NUM>, so that the driving shaft <NUM> can drive the control rod <NUM> to make a piston movement relative to the transmission main body <NUM>. Preferably, the first gear assembly <NUM> is arranged on an end of the driving shaft <NUM> away from the motor main body <NUM>.

By controlling a rotation direction and a rotation angle of the driving motor <NUM>, the transmission assembly <NUM> can be controlled to switch between different gear states. For example, when the motor main body <NUM> of the driving motor <NUM> drives the driving shaft <NUM> to rotate counterclockwise, the driving shaft <NUM> drives the control rod <NUM> of the transmission assembly <NUM> to move in a direction away from the transmission main body <NUM>, and when the motor main body <NUM> drives the driving shaft <NUM> to rotate clockwise, the driving shaft <NUM> drives the control rod <NUM> of the transmission assembly <NUM> to move in a direction close to the transmission main body <NUM>, thereby changing the transmission ratio of the transmission main body <NUM> and controlling the transmission assembly <NUM> to switch between different gear states. In at least one embodiment, there can be other correspondences between the rotation direction of the driving shaft <NUM> and a movement direction of the control rod. That is to say, when the driving shaft <NUM> rotates counterclockwise, the driving shaft <NUM> may drive the control rod <NUM> to move in a direction close to the transmission main body <NUM>, and when the driving shaft <NUM> rotates clockwise, the driving shaft <NUM> may drive the control rod <NUM> to move in a direction away from the transmission main body <NUM>. Those skilled in the art should understand that, as long as the objective of the present invention can be achieved, the corresponding relationship between the rotation direction of the driving shaft <NUM> and the movement direction of the control rod <NUM> should not constitute a limitation to the present invention.

Referring to <FIG> and <FIG>, in at least one embodiment, the intelligent harvester with automatic braking function may further include a screw assembly <NUM> arranged between the driving shaft <NUM> of the driving motor <NUM> and the control rod <NUM> of the transmission assembly <NUM>. One end of the screw assembly <NUM> is connected to the driving shaft <NUM>, and the other end of the screw assembly <NUM> is connected to the control rod <NUM>.

Preferably, the screw assembly <NUM> may be arranged between the driving shaft <NUM> and the control rod <NUM>, and may be coaxial with the driving shaft <NUM> and the control rod <NUM>, respectively.

The screw assembly <NUM> may further include a movable groove <NUM> opening in the direction facing the control rod <NUM>, and the end of the control rod <NUM> away from the transmission main body <NUM> is movably disposed in the movable groove <NUM>. Internal threads are arranged on an inner wall defining the movable groove <NUM>, and external threads are arranged on the end of the control rod <NUM> away from the transmission main body <NUM>. The internal threads and the external threads are compatible with each other. The end of the control rod <NUM> away from the transmission main body <NUM> can rotate in the movable groove <NUM>.

The end of the screw assembly <NUM> away from the control rod <NUM> is fixed to the end of the driving shaft <NUM> of the driving motor <NUM> away from the motor main body <NUM>. In at least one embodiment, the end of the screw assembly <NUM> away from the control rod <NUM> may be integrally formed to the end of the driving shaft <NUM> away from the motor main body <NUM>.

The motor main body <NUM> of the driving motor <NUM> and the transmission main body <NUM> of the transmission assembly <NUM> are respectively fixed to the harvester body <NUM>. When the motor main body <NUM> of the drive motor <NUM> drives the drive shaft <NUM> to rotate, the screw assembly <NUM> rotates with the drive shaft <NUM> and at the same drives the control rod <NUM> of the transmission assembly <NUM> to make the piston movement relative to the transmission main body <NUM>, thereby changing the transmission ratio of the transmission main body <NUM>. For example, but not limited to, when the motor main body <NUM> of the driving motor <NUM> drives the driving shaft <NUM> to rotate clockwise, the screw assembly <NUM> drives the control rod <NUM> to move in the direction away from the transmission main body <NUM>. In other words, the control rod <NUM> moves toward the bottom of the movable groove <NUM>. When the motor main body <NUM> of the driving motor <NUM> drives the driving shaft <NUM> to rotate counterclockwise, the screw assembly <NUM> drives the control rod <NUM> to move in the direction close to the transmission main body <NUM>. In other words, the control rod <NUM> moves in a direction away from the bottom of the movable groove <NUM>. That is to say, the transmission assembly <NUM> can be controlled to switch between different gear states by controlling the rotation direction and the rotation angle of the driving motor <NUM>. When the communication detection system <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the controller <NUM> controls the operation of the driving motor <NUM>, and the driving motor <NUM> drives the control rod of the transmission assembly <NUM> to switch to the neutral position, so that the transmission assembly <NUM> is switched to the neutral state.

Referring to <FIG>, in at least one embodiment, the intelligent harvester with automatic braking function may further include a braking assembly <NUM>. The braking assembly <NUM> is operatively connected to the braking system <NUM>. When the communication detection system <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the braking system <NUM> controls the braking assembly <NUM> to brake, so that the harvester body <NUM> can stop moving.

Specifically, the braking system <NUM> may further include a second driving assembly <NUM>. The second driving assembly <NUM> is operatively connected to the controller <NUM> and the braking assembly <NUM>, respectively. When the communication detection system <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the controller <NUM> controls the second driving assembly <NUM> to drive the braking assembly <NUM> to brake, so that the harvester body <NUM> stops moving, and the harvester body <NUM> is prevented from continuing to move without the control of the remote control system <NUM>.

In at least one embodiment, when the communication detection system <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the braking system <NUM> controls the transmission assembly <NUM> to switch to the neutral state, at the same time, the braking system <NUM> can also control the braking assembly <NUM> to brake, so that the harvester body <NUM> can be quickly stopped. That is, when the communication detection system <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the controller <NUM> controls the first driving assembly <NUM> to drive the transmission assembly <NUM> to switch to the neutral state, and at the same time, the controller <NUM> controls the second driving assembly <NUM> to drive the braking assembly <NUM> to brake, so that the harvester body <NUM> can be braked quickly.

The communication detection system <NUM> includes a communication strength detection unit <NUM>, and the communication strength detection unit <NUM> is operatively connected to the wireless communication assembly <NUM> and/or the remote control system <NUM>. The communication strength detection unit <NUM> is used to detect a signal strength between the wireless communication assembly <NUM> and the remote control system <NUM>.

The communication strength detection unit <NUM> is operatively connected to the braking system <NUM>. When the signal strength between the wireless communication assembly <NUM> and the remote control system <NUM> detected the communication strength detection unit <NUM> is less than a preset signal value, the braking system <NUM> controls the harvester body <NUM> to brake.

The communication detection system <NUM> further includes a signal comparison unit <NUM>. The signal comparison unit <NUM> is operatively connected to the communication strength detection unit <NUM>. The signal comparison unit <NUM> is used to obtain a real-time signal strength between the wireless communication assembly <NUM> and the remote control system <NUM> detected by the communication strength detection unit <NUM> from the communication strength detection unit <NUM>, and compare the real-time signal strength and the preset signal value. When the real-time signal strength is less than the preset value, the braking system <NUM> controls the harvester body <NUM> to brake. When the value of the real-time signal strength is greater than the preset signal value, the braking system <NUM> does not control the braking of the harvester body <NUM>, the signal comparison unit <NUM> continues to obtain the real-time signal strength from the communication strength detection unit <NUM>, and compares the real-time signal strength with the preset signal value.

When the signal strength between the wireless communication assembly <NUM> arranged in the harvester body <NUM> and the remote control system <NUM> is less than a certain value, the communication between the wireless communication assembly <NUM> and the remote control system <NUM> will be greatly affected. For example, when the remote control system <NUM> sends a control instruction to the wireless communication assembly <NUM>, since the signal strength between the wireless communication assembly <NUM> and the remote control system <NUM> is weak, the control instruction received by the wireless communication assembly <NUM> may differ from the actual control instruction sent by the remote control system <NUM>. Therefore, the harvester body <NUM> may execute wrong instructions and affect the safety of people's lives and property.

The signal comparison unit <NUM> is operatively connected to the controller <NUM> of the braking system <NUM>. When the real-time signal strength is less than the preset signal value, the controller <NUM> controls the first driving assembly <NUM> to drive the transmission assembly <NUM> to switch to the neutral position, controls the second driving assembly <NUM> to drive the braking assembly <NUM> to brake. or controls the first driving assembly <NUM> to drive the transmission assembly <NUM> to switch to the neutral position and at the same time to drive the braking assembly <NUM> to brake. So that the harvester body <NUM> can brake urgently to prevent the harvester body <NUM> from continuing to move when the signal strength between the wireless communication assembly <NUM> and the remote control system <NUM> is weak.

In at least one embodiment, when the communication detection system <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> is interrupted, the braking system <NUM> controls the harvester body <NUM> to brake. The communication detection system <NUM> includes a communication interruption detection assembly <NUM>, the communication interruption detection assembly <NUM> is operatively connected to the braking system <NUM> and the wireless communication assembly <NUM> respectively. The communication interruption detection assembly <NUM> is used to detect the communication between the wireless communication assembly <NUM> and the remote control system <NUM>. When the communication interruption detection assembly <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> is interrupted, the braking system <NUM> controls the harvester body <NUM> to brake.

Specifically, when the communication interruption detection assembly <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> is interrupted, the controller <NUM> controls the first driving component <NUM> to drive the transmission component <NUM> to switch to the neutral position, controls the second driving assembly <NUM> to drive the braking assembly to brake, or controls the first driving assembly <NUM> to drive the transmission assembly <NUM> to switch to the neutral position and at the same time to drive the braking assembly <NUM> to brake. So that the harvester body <NUM> can brake quickly.

Referring to <FIG>, the intelligent harvester with automatic braking function may further include a positioning assembly <NUM>. The positioning assembly <NUM> is operatively connected to the wireless communication assembly <NUM>. The positioning assembly <NUM> is used to obtain a real-time position of the harvester body <NUM>, and send a position information of the harvester body <NUM> to the remote control system <NUM> through the wireless communication assembly <NUM>, so that the user can obtain the position information of the harvester body <NUM> in real time.

In at least one embodiment, the positioning assembly may be a global position system (GPS).

When the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, and the braking system <NUM> controls the harvester body <NUM> to brake in an emergency, the remote control system <NUM> can no longer obtain the position information of the harvester body <NUM> through the wireless communication assembly <NUM>. When the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the braking system <NUM> controls the harvester body <NUM> to brake, then the position information of the harvester body <NUM> last obtained by the remote control system <NUM> from the wireless communication assembly <NUM> is a position information where the wireless communication assembly <NUM> and the remote control system <NUM> have a communication failure. That is, people only need to determine the last position information of the harvester body <NUM> obtained by the remote control system <NUM> to determine the position information of the harvester body <NUM> when a communication failure occurs between the wireless communication assembly <NUM> and the remote control system <NUM>. So that the position information of the harvester body <NUM> can be quickly obtained, and the communication between the wireless communication assembly <NUM> and the remote control system <NUM> can be quickly repaired.

The intelligent harvester with automatic braking function may further include a delay detection control assembly <NUM>. The delay detection control assembly <NUM> is operatively connected to the communication detection system <NUM>. When the communication detection system <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the delay detection control assembly <NUM> can control the communication detection system <NUM> to re-detect the communication between the wireless communication assembly <NUM> and the remote control system <NUM> again after an interval of a preset time.

During the operation of the intelligent harvester with automatic braking function, the communication between the wireless communication assembly <NUM> and the remote control system <NUM> may have certain fluctuations. For example, if the signal strength between the wireless communication assembly <NUM> and the remote control system <NUM> suddenly weakens, but returns to normal in a short time, then in this case, if the braking system <NUM> controls the harvester body <NUM> to brake and the user waits for maintenance personnel to come and repair the intelligent harvester, it will take a lot of time and greatly reduces the operating efficiency of the intelligent harvester.

Preferably, when the communication detection system <NUM> detects that the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the braking system <NUM> controls the harvester body <NUM> to brake. After the braking system <NUM> controls the harvester body <NUM> to brake for a period of time, the delay detection control assembly <NUM> controls the communication detection system <NUM> to detect the communication between the wireless communication assembly <NUM> and the remote control system <NUM> again. When the communication between the wireless communication assembly <NUM> and the remote control system <NUM> detected again by the communication detection system <NUM> meets a preset condition, the braking system <NUM> controls the harvester body <NUM> to start the operation again. When the communication between the wireless communication assembly <NUM> and the remote control system <NUM> detected again by the communication detection system <NUM> is still faulty, the harvester body <NUM> is not restarted and waits to be repaired.

After the braking system <NUM> controls the harvester body <NUM> to brake, and before the harvester body <NUM> is controlled to start again, the delay detection control assembly <NUM> controls the communication detection system <NUM> to re-detect the communication between the wireless communication assembly <NUM> and the remote control system <NUM> for multiple times, so that the harvester body <NUM> is controlled to move again when the communication between the wireless communication assembly <NUM> and the remote control system <NUM> is completely normal. In other words, after the braking system <NUM> controls the harvester body <NUM> to brake, only when the communication detection system <NUM> detects the communication between the wireless communication assembly <NUM> and the remote control system <NUM> is normal multiple times, the braking system <NUM> controls the harvester body <NUM> to start again.

Referring to <FIG>, a braking method for the intelligent harvester with automatic braking function is also provided according to an embodiment of the present disclosure, which is executed by the intelligent harvester with automatic braking function. The braking method includes following steps.

Step (a): the communication between the wireless communication assembly <NUM> arranged in the harvester body <NUM> and the remote control system <NUM> is detected.

Step (b): if the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the harvester body <NUM> is controlled to brake.

In at least one embodiment, the intelligent harvester with automatic braking function further includes the braking system <NUM> and the transmission assembly <NUM>, when the communication between the wireless communication assembly <NUM> and the remote control system <NUM> fails, the braking system <NUM> controls the transmission assembly <NUM> arranged in the harvester body <NUM> to switch to the neutral position.
