[0036] The embodiment of the present application provides an operation condition monitoring method and system applied to a pineapple transplanter to solve the problem in the related art that the situation of clamping seedlings is not judged in time, resulting in missing planting and affecting the overall operation quality of the transplanter.

[0037] The duckbill planting mechanism can refer to the structural description of the duckbill planting device for a transplanter in CN209897606U.

[0038] Please refer to Figure 1 - Figure 2 , an operation condition monitoring method applied to a pineapple transplanter, which includes the following steps:

[0039] Step 100: Obtain real-time images of the transplanted seedlings in the duckbill planting mechanism within a first set time period;

[0040] Step 101: Obtain the optical signal information detected in the duckbill planting mechanism within the first set time period. The optical signal information includes the disconnection time of the optical signal.

[0041] Step 102: Based on the real-time image, determine whether there is a transplanted seedling in the duckbill planting mechanism.

[0042] Step 103: If not, continue to obtain the real-time image.

[0043] Step 104: If there is, then determine whether the disconnection time of the optical signal is greater than the designed threshold. When the disconnection time of the optical signal is greater than or equal to the designed threshold, it is determined that the seedling clamping situation occurs, and a first-level alarm is issued. At the same time, the real-time image is transmitted to the display device in the tractor cab. When the disconnection time of the optical signal is less than the designed threshold, it is determined to be normal, and the real-time image is transmitted to the display device in the tractor cab at the same time.

[0044] Since it is determined whether there is a transplanted seedling in the duckbill planting mechanism through the real-time image; if not, continue to obtain the real-time image; if there is, then determine whether the disconnection time of the optical signal is greater than the designed threshold. When the disconnection time of the optical signal is greater than or equal to the designed threshold, it is determined that the seedling clamping situation occurs, and a first-level alarm is issued. At the same time, the real-time image is transmitted to the display device in the tractor cab. When the disconnection time of the optical signal is less than the designed threshold, it is determined to be normal, and the real-time image is transmitted to the display device in the tractor cab at the same time. Through the above steps, the real-time monitoring of the seedling clamping situation can be realized, and an alarm can be issued immediately after the seedling clamping occurs. At the same time, the image is displayed, so as to promptly eliminate the seedling clamping situation for the operator in the cab and improve the operation efficiency. At the same time, the above judgment method does not require a complex calculation process, reduces the processing and analysis time, and improves the judgment accuracy.

[0045] In some preferred embodiments, since the seedling clamping situation is caused by the situation of the transplanted seedling itself, or the reason of the duckbill planting mechanism itself, or accidentally caused by the fact that the size of some transplanted seedlings does not meet the specifications. Therefore, for distinguishing the situations, there are the following settings:

[0046] If it is determined that the seedling clamping situation occurs, record one case of seedling clamping.

[0047] Obtain the number of times of seedling clamping within the second set time period. The second set time period includes a plurality of first set time periods arranged in chronological order.

[0048] Judge whether the number of times of seedling clamping within the second set time period is greater than the first designed number.

[0049] If it is greater than or equal to the first designed number, issue a shutdown inspection and maintenance prompt and issue a second-level alarm.

[0050] Such a judgment excludes the influence caused by the non - compliance of the size of some transplanted seedlings. If the number of times exceeds the first designed number, it is considered to be caused by the damage of the mechanism or the inappropriate size of most transplanted seedlings, and it is inclined to repair and replace the appropriate transplanted seedlings.

[0051] Furthermore, obtain the second designed number of times when a secondary alarm is issued within one day; the second designed number of times is greater than the first designed number of times.

[0052] If the number of times the secondary alarm is issued is greater than the second designed number of times, it is determined that the transplanted seedlings on the seedling transplanting tray are too large and do not meet the usage specifications of the duckbill planting mechanism.

[0053] In the previous step, the faults of the mechanism itself are excluded. Therefore, it can only be caused by the too large transplanted seedlings on the seedling transplanting tray, thus providing an effective judgment index for solving the problem of clamping seedlings.

[0054] Among them, the alarm sound decibel of the primary alarm is 60dB - 80dB, and the alarm time is 3 - 5s.

[0055] The alarm sound decibel of the secondary alarm is 100dB - 130dB, and the alarm time is 6 - 10s. The detection component for detecting the optical signal information includes an optical fiber signal generator 1 and an optical fiber signal receiver 2.

[0056] Reference Figure 2 , the optical fiber signal generator 1 and the optical fiber signal receiver 2 are arranged on the inner wall of the duckbill planting mechanism, and the inner wall is the inner wall of the space in the duckbill planting mechanism for passing the transplanted seedlings; the optical fiber signal generator 1 and the optical fiber signal receiver 2 are located on the same horizontal straight line, and this horizontal straight line is perpendicular to the vertical axis of the space. Such a setting can avoid false alarms when normal transplanted seedlings pass through.

[0057] Reference Figure 1 , an operation condition monitoring system applied to a pineapple transplanter, which includes:

[0058] A monitoring module, which is used to obtain real - time images of the transplanted seedlings in the duckbill planting mechanism within the first set time period.

[0059] An alarm module, which is used to obtain the optical signal information detected in the duckbill planting mechanism within the first set time period, and the optical signal information includes the disconnection time of the optical signal.

[0060] A processing and analysis module, which is used to judge whether there are transplanted seedlings in the duckbill planting mechanism based on real-time images; if not, continue to obtain real-time images, and at the same time use the monitoring module to transmit the real-time images to the display device in the tractor cab; if so, judge whether the disconnection time of the optical signal is greater than the designed threshold. When the disconnection time of the optical signal is greater than or equal to the designed threshold, it is determined that the clamping of seedlings occurs, and a first-level alarm is issued by using the alarm module. At the same time, the monitoring module is used to transmit the real-time images to the display device in the tractor cab; when the disconnection time of the optical signal is less than the designed threshold, it is determined to be normal, and at the same time the monitoring module is used to transmit the real-time images to the display device in the tractor cab; if it is determined that the clamping of seedlings occurs, record one case of clamping of seedlings.

[0061] Obtain the number of times of clamping of seedlings in the second set time period; the second set time period includes a plurality of the first set time periods arranged in chronological order.

[0062] Judge whether the number of times of clamping of seedlings in the second set time period is greater than the first designed number.

[0063] If it is greater than or equal to the first designed number, a shutdown inspection and maintenance prompt is issued, and a second-level alarm is issued; obtain the second designed number of times of issuing the second-level alarm within one day; the second designed number is greater than the first designed number; if the number of times of issuing the second-level alarm is greater than the second designed number, it is determined that the transplanted seedlings on the transplanted seedling tray are too large and do not meet the use specifications of the duckbill planting mechanism.

[0064] The monitoring module includes a camera, a network hard disk video recorder, and a display device located in the tractor cab that are signal-connected. The alarm module includes a fiber optic signal generator 1, a fiber optic signal receiver 2, a fiber optic signal amplifier, a wireless alarm transmitter, a wireless alarm receiver, and an audible and visual alarm; the wireless alarm transmitter is installed on the duckbill planting mechanism, and the wireless alarm receiver and the audible and visual alarm are installed in the tractor cab. The signal transmission between the monitoring module and the alarm module and the processing and analysis module is carried out by using the Ethernet method.

[0065] It also includes a remote controller, which is used to control the opening and closing of the audible and visual alarm of the alarm module. In this way, it can be closed immediately after the alarm, so as to avoid the continuous noise caused by the alarm sound. The remote controller can manually turn on / off the alarm.

[0066] Through the above settings, by monitoring the stagnation time of pineapple seedlings in the duckbill planting mechanism, it is judged whether there is a phenomenon of stuck seedlings for pineapple seedlings. When a certain pineapple seedling has a phenomenon of stuck seedlings, the audible and visual alarm in the cab gives an alarm reminder, and the operator can check the planting situation of the pineapple seedlings through the display device, which can assist the operator to make a judgment on the stuck seedlings in time.

[0067] Advantages of this application:

[0068] Since it is judged whether there are transplanted seedlings in the duckbill planting mechanism through real-time images; if not, continue to obtain real-time images; if so, then judge whether the disconnection time of the optical signal is greater than the designed threshold. When the disconnection time of the optical signal is greater than or equal to the designed threshold, it is determined that the seedling clamping situation occurs, and a first-level alarm is issued. At the same time, the real-time image is transmitted to the display device in the tractor cab; when the disconnection time of the optical signal is less than the designed threshold, it is determined to be normal, and the real-time image is transmitted to the display device in the tractor cab at the same time; through the above steps, the real-time monitoring of the seedling clamping situation can be realized, and an alarm can be issued immediately after the seedling clamping occurs, and the image is displayed at the same time, so as to promptly eliminate the seedling clamping situation for the operator in the cab and improve the operation efficiency. At the same time, the above judgment method does not require a complex calculation process, reduces the processing and analysis time, and improves the judgment accuracy rate.

[0069] Since the seedling clamping situation is caused by the situation of the transplanted seedlings themselves, or the reason of the duckbill planting mechanism itself, or accidentally caused by the fact that the sizes of some transplanted seedlings do not meet the specifications, in order to distinguish the situations, the following settings are made: if it is determined that the seedling clamping situation occurs, record one time of seedling clamping; obtain the number of times of seedling clamping in the second set time period; the second set time period includes a plurality of first set time periods arranged in chronological order; judge whether the number of times of seedling clamping in the second set time period is greater than the first designed number; if it is greater than or equal to the first designed number, issue a prompt for shutdown inspection and maintenance, and issue a second-level alarm.

[0070] Such a judgment excludes the influence caused by the fact that the sizes of some transplanted seedlings do not meet the specifications. If it exceeds the first designed number, it is considered to be caused by the damage of the mechanism or the inappropriate sizes of most transplanted seedlings, which is conducive to maintenance and replacement of suitable transplanted seedlings.

Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
