Wireless detection device and detection method for blooming state of rice spikelet

Abstract

The invention relates to a wireless detection device for the blooming state of rice spikelet, and the device comprises a camera which collects the image of the blooming state of the rice spikelet in real time; the image transmitting module is used for transmitting rice spikelet image information; the image transmission receiving module is used for receiving the rice spikelet image information; the video acquisition card is used for converting the analog signal output by the image transmission receiving module into a digital signal through processing; the processor is used for processing the digital images of the rice spikelet in real time and detecting the blooming state of the rice spikelet; the data transmission transmitting end is used for transmitting the rice spikelet blooming state information detected by the processor; the data transmission receiving end is connected with a flight controller of the plant protection unmanned aerial vehicle, and the plant protection unmanned aerial vehicle is controlled by the flight controller to automatically fly according to a preset route to pollinate rice spikelet. The invention further relates to a wireless detection method for the blooming state of the rice spikelet. The system can accurately detect the blooming state of glumous flowers, controls the plant protection unmanned aerial vehicle to pollinate, is high in automation degree and accuracy, and belongs to the field of agricultural condition monitoring.

Description

technical field [0001] The invention relates to the field of agricultural condition monitoring, in particular to a wireless detection device and detection method for the blooming state of rice spikelets. Background technique [0002] In general, the daily flowering amount of rice spikelets changes with time in a bell-shaped curve. When the amount of flowering on the same day reaches the maximum value, that is, when the flowers are in full bloom, rice pollination can ensure that the effect of hybrid rice seed production reaches the best. However, rice florets are small in size, and the duration of full bloom is short, so it is difficult to grasp the timing of pollination. [0003] At present, rice production is to rely on experience to judge the flowering situation of rice spikelets through farmers' visual inspection, and to arrange the time of pollination. The flowering time in a single day can last for several hours. In order not to miss the full bloom, farmers must obser...

Problems solved by technology

[0004] Although some existing surveillance cameras or plant protection drones can collect images of rice spikelets and store them in SD cards, they do not have the function of analyzing the blooming status of rice spikelets and cannot guide the pollination of plant protection drones

There are mainly the following defects: 1. The drone has a short battery life and cannot monitor rice florets for a long time

2. The surveillance camera and the PTZ camera mounted on the drone can only collect images of rice florets and store them in the SD card, but cannot analyze the blooming state of rice florets

3. The flight control of general plant protection drones does not have the ability of large-scale computing, and cannot independently analyze the collected rice floret images to determine the best time for pollination
