[0047] It can be understood that the term “a” should be understood as “at least one” or “one or more”, that is, in one embodiment, the number of a kind of element may be one, and in another embodiment, the number of the kind of element can be more than one, and the term “one” cannot be understood as a restriction on the number.

[0048] Referring to FIGS. 1 to 7, an intelligent harvester with instantaneous stop functions is provided according to an embodiment of the present disclosure. The intelligent harvester with instantaneous stop functions can automatically complete the operation task without a driver and take emergency braking measures when an emergency occurs during the operation, to prevent injury to human body, thereby improving the safety of the harvester. Specifically, the intelligent harvester with instantaneous stop functions is a crawler type intelligent harvester, that is, the intelligent harvester with instantaneous stop functions drives a harvester body to move by contacting a crawler with the ground, so as to effectively increase the contact area with the ground. On the contrary, the intelligent harvester falls into the land when operating on a relatively soft land, which effectively improves the operation efficiency and adaptability of the intelligent harvester to the land.

[0049] The intelligent harvester with instantaneous stop functions includes a harvester body 10, a detecting system 20 arranged on the harvester body 10, and a brake system 30 arranged on the harvester body 10. The brake system 30 is operatively connected to the harvester body 10 and the detecting system 20. The detecting system 20 is configured to detect the environmental information on a traveling route. When the detecting system 20 detects an emergency on the traveling route of the harvester body 10, the brake system 30 takes braking measures to control the harvester body 10 to stop moving.

[0050] Furthermore, when the detecting system 20 detects an emergency on the traveling route of the harvester body 10, the detecting system 20 generates a first detection information 210, the brake system 30 obtains the first detection information 210 from the detecting system 20, and controls the harvester body 10 to take emergency braking measures according to the first detection information 210, so as to control the harvester body 10 to stop quickly. The emergency on the traveling route of the harvester body 10 refers to the human body on the traveling route of the harvester body 10. In other words, when the detecting system 20 detects a human body appeared on the traveling route of the intelligent harvester body 10, the detection system 20 generates the first detection information 210.

[0051] The detecting system 20 further includes at least one first infrared detector 21 arranged on the harvester body 10. The first infrared detector 21 is used to detect a human body on the traveling route of the harvester body 10 by an infrared detection manner. The first infrared detector 21 is operatively connected to the brake system 30. When the first infrared detector 21 detects a human body appeared in front of the harvester body 10 on the traveling route of the harvester body 10, the first detection information 210 is generated, the brake system 30 obtains the first detection information 210 from the first infrared detector 21 and controls the harvester body 10 to take emergency brake.

[0052] The first infrared detector 21 is arranged at a front end of the harvester body 10 and configured to detect whether a human body is present on a traveling route in front of the harvester body. During the operation of the harvester with instantaneous stop functions, when a human body suddenly appears on the traveling route in front of the harvester body 10, the first infrared detector 21 arranged at the front end of the harvester body 10 can detect the presence of the human body and generate the first detection information 210, the brake system 30 controls the harvester body 10 to take emergency braking measures based on the first detection information 210 to the harvester body 10 from moving forward, which will cause injury to the human body who suddenly appears on a forward route of the harvester body 10, thus the safety of the harvester is improved.

[0053] The first infrared detector 21 is a passive infrared detector with Fresnel lenses, which can effectively avoid the influence of small animals on the detection results. That is, the first detection information 210 generated after the first infrared detector 21 detects a human body present on a traveling route in front of the harvester body 10. When the first infrared detector 21 detects a small animal present on a traveling route in front of the harvester body 10, the first infrared detector 21 does not generate the first detection information, so that the accuracy of the detecting result of the first infrared detector 21 is improved.

[0054] The brake system 30 further includes a controller 31 and a first driving assembly 32. The controller 31 is operatively connected to the detecting system 20 and the first driving assembly 32. The controller 21 and the first driving assembly 32 are arranged on the harvester body 10, the first driving assembly 32 is driveably connected to a commission assembly 11 of the harvester body 10, and the first driving assembly 32 can drive the commission assembly 11 of the harvester body 10 to switch between different gear positions.

[0055] Specifically, the controller 31 of the brake system 30 is operatively connected to the first infrared detector 21 of the detecting system 20. The controller 30 can obtain the first detection information from the first infrared detector 21 and controls the transmission assembly 11 to switch between different gear positions based on the first detection information.

[0056] When the first infrared detector 21 detects a human body present on a traveling path in front of the harvester body 10, the first infrared detector 21 generates the first detection information 210, the controller 31 obtains the first detection information 210 from the first infrared detector 21 and controls the first driving assembly 32 according to the first detection information, the first driving assembly 32 controls the transmission assembly 11 to switch to a neutral position, so that the harvester body 10 stops moving.

[0057] Specifically, the transmission 11 arranged on the harvester body 10 is a hydro static transmission (HST), the first driving assembly 32 is operatively connected to the HST. When the first infrared detector 21 detects a human body on a traveling route in front of the harvester body 10 and generates the first detection information 210, the controller 31 controls the first driving assembly 32 according on the first detection information 210, the first driving assembly 32 drives the HST to switch to the neutral position, so that the harvester body 10 stops moving.

[0058] The first driving assembly 32 is a drive motor, which is driveably connected to the transmission assembly 11 of the harvester body 10, that is, the drive motor is driveably connected to the HST, and the drive motor can drive the HST to switch between different gear positions. When the first infrared detector 21 detects a human body on the traveling route in front of the harvester body 10, the first detection information 210 is generated, the controller 31 obtains the first detection information 210 and controls the drive motor according to the first detection information, the drive motor controls the HST to switch to the neutral position, so that the harvester body 10 stops moving, thus avoiding injuring to the human body who suddenly appears on the traveling route in front of the harvester body 10 and improving the safety of the harvester.

[0059] Referring to FIGS. 4 and 5, a detection area of the first infrared detector 21 of the intelligent harvester is provided. The first infrared detector 21 is arranged at the front end of the harvester body 10, the first infrared detector 21 can detect a human body within an area range on the traveling route in front of the harvester body 10. Preferably, a horizontal width of the detection area on the traveling route in front of the harvester body 10 that can be detected by the first infrared detector 21 is equivalent to a horizontal width of the harvester body 10, and a vertical height of the detection area on the traveling route in front of the harvester body 10 that can be detected by the first infrared detector 21 is equivalent to a vertical height of the harvester body 10. An angle of the first infrared detector 21 arranged on the harvester body 10 can be changed to change the horizontal range and vertical range of the area that can be detected by the first infrared detector 21.

[0060] Referring to FIG. 5, in some embodiments, the number of the first infrared detectors 21 arranged on the harvester body 10 can also be, but not limited to, two, three, four, five, six, etc. As long as the purpose of the disclosure can be achieved, the number of the first infrared detectors 21 arranged on the harvester body 10 should not constitute a limitation on the disclosure.

[0061] Referring to FIG. 6, an intelligent harvester with identification functions is provided according to a first variant embodiment of the present disclosure. In the intelligent harvester with identification functions of the first variant embodiment, the detecting system 20 further includes a second infrared detector 22, the second infrared detector 22 is arranged at a rear end of the harvester body 10, and the second infrared detector 22 is used to detect a human body within an area range behind the harvester body 10. The second infrared detector 22 is operatively connected to the controller 31. During the revers travel of the harvester body 10, when the second infrared detector 22 detects a human body within a certain distance from the rear end of the harvester body 10, the second infrared detector 22 generates a second detection information 220. The controller 31 can obtain the second detection information 220 from the second infrared detector 22 and controls the first driving assembly 32 according to the second detection information 220, and the first driving assembly 32 drives the transmission assembly 11 to switch to the neutral position, so that the harvester body 10 stops moving.

[0062] The second infrared detector 22 is also a passive infrared detector with Fresnel lens, which can effectively prevent the influence of small animals on the accuracy of detection results and improve the accuracy of detection results of the second infrared detector 22.

[0063] The detecting system 20 further includes a third infrared detector 23 and a fourth infrared detector 24. The third infrared detector 23 and the fourth infrared detector 24 are respectively arranged on the left and right sides of the harvester body 10, the third infrared detector 23 is used to detect a human body within an area range on the left side of the harvester body 10, and the fourth infrared detector 24 is used to detect a human body within an area range on the right side of the harvester body 10.

[0064] The third infrared detector 23 and the fourth infrared detector 24 are operatively connected to the controller 31. During the left turn of the harvester body 10, when the third infrared detector 23 detects a human body within the area range on the left of the harvester body 10, the third infrared detector 23 generates a third detection information 230. The controller 31 can obtain the third detection information 230 and controls the first driving assembly 32 according to the third detection information 230, and the first driving assembly 32 drives the transmission assembly 11 to switch to the neutral position, so that the harvester body 10 stops turning to the left, thus avoiding injuring to the human body who appears within an area range on the left of the harvester body 10. During the right turn of the harvester body 10, when the fourth infrared detector 24 detects a human body within an area range on the right of the harvester body 10, the fourth infrared detector 24 generates a fourth detection information 240. The controller 31 can obtain the fourth detection information 240 from the fourth infrared detector 24 and controls the first driving assembly 32 according to the fourth detection information, and the first driving assembly 32 drives the transmission assembly 11 to switch to the neutral position, so that the harvester body 10 stops turning to the right.

[0065] Each of the third infrared detector 23 and the fourth infrared detector 24 is a passive infrared detector with Fresnel lens, which can effectively prevent the influence of small animals on the accuracy of detection results and improve the accuracy of detection results of the third infrared detector 23 and the fourth infrared detector 24.

[0066] The detection areas formed by the first infrared detector 21, the second infrared detector 22, the third infrared detector 23 and the fourth infrared detector 24 are adjacent to each other. The detection areas of the four infrared detectors jointly surround the harvester body, thereby detecting the human bodies around the harvester body in an all direction. That is, the human body at any position around the harvester body 10 can be detected by the first infrared detector 21, the second infrared detector 22, the third infrared detector 23 or the fourth infrared detector 24, so as to ensure the safety of the human body during the operation of the harvester body 10, the safety of the harvester body is improved.

[0067] The detection range of each of the first infrared detector 21, the second infrared detector 22, the third infrared detector 23, and the fourth infrared detector 24 is 5 m, that is, when there is someone within 5 meters from the harvester body 10, at least one of the first infrared detector 21, the second infrared detector 22, the third infrared detector 23, and the fourth infrared detector 24 can detect the presence of a human body and send a corresponding detection information to the controller 31.

[0069] Specifically, when the first infrared detector 21 detects a human body who appears on the traveling path in front of the harvester body 10, the first infrared detector 21 generates the first detection information 210, the controller 31 controls the second driving assembly 33 according to the first detection information 210, and the second driving assembly 33 drives the brake assembly 12 to brake, so that the harvester body 10 stops moving, thus avoiding injuring to the human body who suddenly appears on the traveling path of the harvester body 10, the safety of the intelligent harvester is improved.

[0070] It is to be understood, while the controller 31 obtains the first detection information 210 to control the second drive assembly 33 to drive the brake assembly 12 to brake, the controller 31 simultaneously controls the first drive assembly 32 to control the transmission assembly 11 to switch to the neutral position. In other words, when the controller 31 obtains the first detection information 210, the controller 31 controls the brake assembly 12 to brake suddenly and simultaneously controls the transmission assembly 11 to switch to the neutral position, so that the harvester body 10 can be braked suddenly, thus avoiding injuring to the human body who suddenly appears on the traveling path in front of the harvester body 10, the safety of the intelligent harvester is improved.

When the infrared detectors detect a human body who appears on the traveling route of the harvester body 10, the first driving assembly 32 drives the first transmission assembly 11 arranged on the harvester body 10 to switch to the neutral position.

[0083] The intelligent harvester further includes the second driving assembly 33 operatively connected to the controller 31, the second driving assembly 33 is operatively connected to the brake assembly 12 arranged on the harvester body 10.
