Problems solved by technology

However, this exclusion method is only applicable to the situation where the distance between the detection objects is relatively large. If the distance between the detection objects moving forward and backward is too small, the front and rear infrared probes will be triggered at the same time, and it will not be possible to detect non-identical objects. Efficient exclusion of detection objects

Embodiment 1

[0022] Such as figure 1 and figure 2 As shown, an exclusion-type infrared counting device for counting the attendance of Italian bee colonies includes a beehive front wall 1, a beehive bottom plate 2, a reflective infrared probe 4, an infrared temperature sensor 5 and a computing unit. The bottom of the beehive front wall 1 and the upper surface of the beehive bottom plate 2 are provided with 6 access holes 3 with a diameter of 5 mm, and the 6 access holes 3 are arranged in a row at the bottom of the beehive front wall 1 . Six reflective infrared probes 4 are respectively fixed on the front wall 1 of the beehive, and the lower bottom surface of each reflective infrared probe 4 sticks to the upper part of each access hole 3 . Six infrared temperature sensors 5 are respectively fixed on the bottom plate 1 of the beehive, and the upper ends of the infrared temperature sensors 5 are attached to the bottom of the access hole 3 . The reflective infrared probe 4 and the infrared t...

Embodiment 2

[0029] An exclusion-type infrared counting device for counting the number of attendances of middle bee colonies. The difference between this implementation and Example 1 is that the number of entrance and exit holes 3 is reduced to 3 because the general group potential of middle bees is weaker than that of bees. , and the diameter of the access hole 3 is reduced to 4.2mm, so as to limit the middle bees to pass through the access hole 3 one by one.

Abstract

The invention provides an exclusion type infrared counting device. The device comprises infrared probes, infrared temperature sensors and an operation unit, wherein the infrared probes are fixed aboveinlet-outlet channels; the infrared temperature sensors are fixed below the channels; the data output ends of the infrared probes and the infrared temperature sensors are all connected with the operation unit; and detected objects are counted by the operation unit only when the detection values of the infrared temperature sensors are within a predetermined temperature range. The exclusion type infrared counting device disclosed by the invention has the beneficial effects that the exclusion counting is carried out by using temperature parameters of objects per se moving in the forward and reverse directions; and the defect that the exclusion counting cannot be carried out on densely-arranged discontinuous objects by using a conventional infrared displacement separation method is overcome.The invention also provides an exclusion type infrared counting device for counting attendance numbers of swarms to ensure that the accurate counting of the attendance numbers of the swarms is realized by performing detection exclusion by comparing the body temperatures of bees flying in and out of hives.

Description

technical field [0001] The invention relates to an infrared detection device, in particular to an exclusion type infrared counting device. Background technique [0002] Infrared counters are widely used in the research of counting the flow of discontinuous objects, but most of the existing infrared counters cannot distinguish the flow direction of objects. As long as an object passes through the infrared detection area, the counter will be triggered to count. In practical applications, it is often necessary to obtain the one-way flow of a certain object for research, so it is necessary to exclude the reverse moving object. Chinese invention patents CN201210174190 and CN201510354813 respectively disclose an infrared counting device for one-way counting of objects. The time difference of the infrared counter to distinguish between forward moving objects and reverse moving objects. However, this exclusion method is only applicable to the situation where the distance between t...
