Pneumatic pollination control device and method for seed production of hybrid rice with large ration of male and female parents

Abstract

The invention discloses a pneumatic pollination control device and method for seed production of hybrid rice with a large ration of male and female parents. The device comprises a bottom plate, fans,a wind speed sensor, an airflow adapter, fan drivers, a processing chip, a wireless transmission module, an electronic compass module, an integrated circuit board, an upper cover and a touch screen, wherein each fan is driven by independent fan driver; the wireless transmission module receives environmental natural wind speed and wind direction information; the electronic compass module determinesthe advancing direction of a pollination machine; after a controller calculates a target output wind speed, the processing chip calculates in real time according to a preset algorithm to obtain a corrected wind speed, so that pollen floats to a target area; the wind speed sensor detects the wind speed of a wind outlet and transmits the wind speed back to the processing chip in real time to form closed-loop control; and the pollination machine can still enable the operating pollen to move in a target state under the condition of the disturbance of external natural wind. The pneumatic pollination control device is simple and compact in overall structure, simple in interaction and high in reliability, and a fan control device with excellent performance is provided for the pneumatic pollination machine of the hybrid rice.

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
