Embodiment Construction

[0019] A method for judging honeybee segregation behavior by using temperature changes, the method specifically includes the following steps:

[0020] Step 1: Deploy two temperature detection points in each honeycomb, obtain the 24-hour honeycomb temperature data for each month of the year through the wireless temperature acquisition device, and average the hourly data to form a daily temperature change data vector where n=24;

[0021] Step 2: Randomly select k cluster centroid points from the daily temperature change data vector set as

[0022] Step 3: For each sample x in the data vector set (i) , computing its distance to each centroid:

[0023]

[0024] Step 4: Select the minimum distance value, and the centroid T corresponding to this value j As this sample x i The class to which it belongs, namely:

[0025]

[0026] Step 5: For each class, recalculate the new centroid:

[0027]

[0028] Where m is the number of data sets, 1{c (i) =j} is an indicator fu...

Abstract

The invention discloses a method for judging swarming behavior of bees by utilizing temperature change. The method comprises the following steps: as the activity of bees in a honeycomb before swarming causes the rise of temperature of a swarm, a sensitive temperature point, namely a swarming early-warning temperature threshold, is set by utilizing the temperature rise characteristic in the design, wherein the temperature change in the honeycomb corresponding to the temperature change is most sensitive; in a plurality of honeycombs of a beehive structure, two wireless temperature sensor monitoring nodes are set corresponding to each honeycomb, so as to realize the accurate temperature detection; swarming early-warning temperature threshold is acquired by adopting honeycomb temperature change algorithm through utilizing a K-means method for clustering analysis, the temperature threshold acquired by a wireless sensing network is compared with the swarming early-warning temperature threshold, if the temperature value is greater than the swarming early-warning temperature threshold, that swarming behavior occurs in the honeycomb can be judged.

Description

technical field [0001] The invention relates to a method for judging the segregation behavior of bees, in particular to a method for judging the segregation behavior of bees by using temperature changes. Background technique [0002] After the number of individuals in the bee colony reaches a certain number, the number of worker bees is too large, resulting in crowded hives. If artificial expansion of the hive is not carried out, the bee colony can only alleviate the crowded situation of the hive by dividing the hive. Separation is a special way of reproduction. For swarming, two explanations can be put forward: insufficient honey production, more hives are used as daughter spleens, and the queen bee lays more eggs at this time, which must be solved by swarming; or due to hormones The reasons for this cause the birth of a new queen bee and force the old queen bee to leave the nest. Natural swarming is the only way for bee populations to proliferate, and beekeepers have to ...
