Problems solved by technology
[0005] At present, the trajectory tracking technology for continuous curves has reached a very mature stage and has been widely used in some fields. The precise tracking and control of the non-continuous target vertex positions on the top of several crop plants in a single row is still a technical bottleneck that needs to be tackled.

Embodiment Construction
[0040] Below in conjunction with accompanying drawing and embodiment the present invention will be further described
[0041] figure 1 The middle is the flow chart of the electro-hydraulic control system applying the trajectory tracking control method of the present invention. The working process of the system is: using the scanning delay method, the individual crops in the same row are virtualized as three-dimensional crop plants with varying vertex heights at the speed u. On the plane, the upper and lower side-by-side photoelectric sensors arranged at the front end of the system track the position P of the plant top, and send the searched position information of the plant top to the information processing module 9, and the processed information is converted into driving power by the signal amplification module 8 and transmitted to the The electromagnetic hydraulic integrated valve block 6, the integrated valve block 6 opens the corresponding hydraulic oil circuit according t...

The invention relates to the technical field of electronic control over agriculture equipment and specifically a single crop plant top locus automatic tracking control method for a corn castration machine and a cotton topping machine. The single crop plant top locus automatic tracking control method is characterized in that a plant top position object is searched via a photoelectric identification time-delay means; after collected object locus information and an expected staminate top locus are subjected to contrast amplifying operation via an information processing and amplifying module, an instruction is sent to an electromagnetic hydraulic valve block, the electromagnetic hydraulic valve block controls a telescoping direction and delay time of a tracking mechanism oil cylinder according to a position offset instruction, a tracking mechanism drives an execution mechanism which is connected below the tracking mechanism, a speed regulation support rack mechanism and a plant top position monitoring device mounted on a front end of a support rack to move simultaneously. The changed plant top position monitoring device continues to search the current plant top object at a current position, and information is sent to the information processing module. Pre-traced distance can be adjusted timely, comprehensive measures of parallel four-link mechanism tilting motion are taken, profiling offset generated via tracking lag can be compensated, and a removal omission rate can be effectively lowered.
Description
technical field [0001] The invention relates to the electronic control technology of agricultural equipment, in particular to the track tracking control of the field plant tops of corn topping machines and cotton topping machines. Background technique [0002] Field de-topping of corn seeds is usually carried out at the stage of tasseling when the plant height is 1.5-2.0 meters. The construction period is short, the environment is harsh, the task is heavy, and the quality of the de-topping operation is high. During the cotton field topping period, the construction period is short and the workload is heavy, requiring a lot of manpower. [0003] Some agricultural developed countries in Europe and the United States have realized mechanized detasseling operations, such as the detasseling spraying machine of Bourgoin in France, the 204 detasseling machine of Hagie in the United States, and the PDF752D detasseling machine of Big John in the United States. Automatic tracking funct...
