Pneumatic pollination control device and method for large row ratio hybrid rice seed production

Abstract

The invention discloses a large-row-ratio hybrid rice seed production pneumatic pollination control device and a control method thereof. The device includes a base plate, a fan, a wind speed sensor, an airflow transfer pipe, a fan driver, a processing chip, a wireless transmission module, and an electronic compass module. , integrated circuit board, upper cover, touch screen. Each fan is driven by a separate fan driver, the wireless transmission module receives the environmental natural wind speed and wind direction information, and the electronic compass module determines the direction of the pollinator. After calculating the target output wind speed through the controller, the processing chip calculates in real time according to the preset algorithm The corrected wind speed is obtained, so that the pollen falls to the target area, and the wind speed of the tuyere is detected by the wind speed sensor and sent back to the processing chip in real time to form a closed-loop control; so that the pollinator can still make the pollen to the target even when the pollinator is disturbed by the external natural wind. State movement; the overall structure is simple and compact, the interaction is simple, and the reliability is high, providing a fan control device with excellent performance for the hybrid rice pneumatic pollinator.

Description

technical field [0001] The invention relates to the field of hybrid rice seed production machinery, in particular to a dynamic airflow velocity control device applicable to pneumatic pollination of hybrid rice. Background technique [0002] Pollination is one of the important steps in the production process of hybrid rice. At present, the methods of artificial pollination of hybrid rice can be divided into manpower and mechanical methods. The flowering period of rice is short, the life span of pollen is not long, the labor intensity of manual pollination is high, and the production efficiency is low, which cannot meet the development requirements of rice seed production technology at the present stage. Mechanical pollination can be mainly divided into impact type and pneumatic type. The collision type is to collide with the male parent to achieve the purpose of pollination, but it is easy to cause damage to the plant; the pneumatic type pollination uses the airflow to blow...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the pollen of the existing pneumatic pollination machine cannot move in the target state due to the influence of external natural wind. A type pollination control device and method thereof, which can automatically adjust the airflow velocity at the outlet of the pneumatic pollination tube in real time by comprehensively integrating the wind speed and direction of the hybrid rice planting field, the forward direction of the pollinator, the shedding of pollen and the stable delivery airflow velocity, and using the wind velocity sensor to detect the airflow velocity in the pollination tube in real time And send it back to the processing chip to form a closed-loop control, so that the large-scale pneumatic pollinator can still make the pollen move in the predetermined target state even when it is disturbed by the external natural wind; the overall structure is simple and compact, the interaction is simple, and the reliability is high. Provides an airflow control device with excellent performance for hybrid rice pneumatic pollinators
