Background

In order to protect crops from pests, a common method is, for example, spraying pesticides. However, spraying too much pesticide not only causes cost increase, but also causes a problem of excessive pesticide residue on crops. Therefore, the current corresponding method needs to count the total number of the insects on site, thereby being used as the basis for adjusting the pesticide spraying amount.

However, to ensure that the pesticide spray dose is able to accurately suppress the remaining insects, a more efficient and accurate solution is needed for on-site counting of the total number of insects.

Another embodiment of the present invention provides a counting method of an insect catching device, comprising several steps as follows. A first photo interrupter is used for photo-sensing in a funnel element. Whether the first photo interrupter senses light reflection in the funnel element is judged.

Detailed Description

In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the present invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, these implementation details are not necessary in the embodiments of the present invention. In addition, some conventional structures and elements are shown in simplified schematic form in the drawings.

FIG. 1 shows a schematic view of an insect catching device 10 according to an embodiment of the present invention. Fig. 2 shows an exploded view of fig. 1. As shown in fig. 1 and 2, the insect catching device 10 includes a container 100, a funnel member 200, a first photo-interrupter 300 and a controller 500. The container 100 has an inlet 111 and a receiving space 130. The inlet 111 is located at the top end of the container 100, and the accommodating space 130 is located in the container 100 and connected to the inlet 111 for accommodating insects. By way of example, and not by way of limitation, the container 100 may be a can or bottle comprising a body 120 and a neck 110 interconnected, the neck 110 being narrower than the body 120, and the inlet 111 being located at one end of the neck 110 and being the only opening of the container 100. The funnel element 200, which has a light absorbing color, such as black or dark color, is disposed on the inlet 111 and extends into the accommodating space 130. For example, the funnel 200 is made of black plastic to reduce internal reflection. A first light interrupter 300 is located in the inner channel 240 of the funnel element 200 for sensing insects passing through the inner channel 240. The controller 500 is electrically connected to the first photo-interrupter 300 for counting the number of insects passing through the inner channel 240 according to the sensing of the first photo-interrupter 300. The controller 500 is configured to send the count value to an external device, such as a notebook computer or a cloud server.

However, the invention is not limited thereto, and in other embodiments all of the inner walls of the inner channel 240 of the funnel element 200 have a light absorbing coating.

For example, in the present embodiment, the funnel element 200 has an outer expanding portion 210, a narrow tube 220 and a stopping portion 230. The flaring portion 210 is suspended from the inlet 111 at the top end of the container 100. The narrow tube 220 is tapered with respect to the enlarged portion 210 and is tapered inward to be narrow. A narrow tube 220 connects the flared section 210 and extends into the container 100. One side of the narrow tube 220 includes a first opening 221, and the first opening 221 communicates with the inner passage 240. A stop 230 is located between flared portion 210 and narrow tube 220 to prevent insects from moving from narrow tube 220 into flared portion 210. The narrow tube 220, the stop portion 230 and the flared portion 210 together define the inner channel 240.

In the present embodiment, the first photo interrupter 300 includes a first board 310, a first light emitting diode 320 and a first photodiode 330. The first plate body 310 is located on the side of the narrow tube 220, covering the first opening 221. The first light emitting diode 320 is located on the first board 310, and extends into the inner channel 240 through the first opening 221, so as to emit light in the inner channel 240. The first photodiode 330 is disposed on the first board 310 and extends into the inner channel 240 through the first opening 221 for performing light sensing in the inner channel 240. For example, the first light emitting diode 320 and the first photodiode 330 are integrally packaged in an integrated device.

Thus, when the first led 320 emits light toward the other side of the narrow tube 220 in the inner channel 240 and no insect passes through, the light emitted by the first led 320 can be substantially absorbed by the inner wall of the funnel element 200, so that the first led 330 cannot sense light or can sense only low light reflection; conversely, when the first led 320 emits light toward the other side of the narrow tube 220 in the inner channel 240 and just insects pass through, the reflected light of the insects can be sensed by the first photodiode 330.

In addition, the insect catching device 10 further includes an upper cover 600. The upper cap 600 is placed over the flared portion 210 of the funnel 200 and the top end of the container 100. The cover 600 has a window 610, the window 610 being aligned with the flared portion 210 of the funnel element 200 and opening the inner channel 240 of the funnel element 200 to allow insects to enter the inner channel 240 of the funnel element 200 from the window 610.

Furthermore, the insect catching device 10 comprises an insect attracting element 700. The insect attracting element 700 is located in the accommodating space 130 to attract insects into the container 100. The insect attracting element 700 is, for example, a light emitting source or hormone.

Fig. 3 is a schematic diagram illustrating a funnel element 200 and a photo interrupter according to an embodiment of the invention. As shown in FIG. 3, the insect catching device 10 further includes a second photointerrupter 400. The second photo interrupter 400 is electrically connected to the controller 500, is disposed in the inner channel 240 of the funnel 200, and is spaced apart from the first photo interrupter 300 along the long axis direction L of the narrow tube 220, respectively, for sensing insects passing through the inner channel 240. Since the insects may swing back and forth on the first photo-interrupter 300 to cause erroneous judgment of the repeated counting, the controller 500 causes the controller 500 to count the insects passing through the inner channel 240 only when the first photo-interrupter 300 and the second photo-interrupter 400 sense the insects at the same time.

More specifically, the side of the narrow tube 220 also includes a second opening 222. The second opening 222 communicates with the inner channel 240, and is spaced from the first opening 221 along the longitudinal direction L of the inner channel 240.

The insect catching device 10 further includes a second plate 410, a second light emitting diode 420 and a second photodiode 430. The second plate 410 is located on this side of the narrow tube 220 and covers the second opening 222. The second light emitting diode 420 is disposed on the second board 410, and extends into the inner channel 240 through the second opening 222 for emitting light in the inner channel 240. The second photodiode 430 is disposed on the second board 410 and extends into the inner channel 240 through the second opening 222 for performing light sensing in the inner channel 240. For example, the second light emitting diode 420 and the second photodiode 430 are integrally packaged in an integrated device.

Thus, when the second led 420 emits light toward the other side of the narrow tube 220 in the inner channel 240 and no insect passes through, the light emitted by the second led 420 can be substantially absorbed by the inner wall of the funnel element 200, so that the second photodiode 430 cannot sense light or can sense only low light reflection; conversely, when the second led 420 emits light toward the other side of the narrow tube 220 in the inner channel 240 and just when an insect passes through, the reflected light of the insect can be sensed by the second photodiode 430.

It should be understood that the controller 500 is not limited to connecting the first photo interrupter 300 and the second photo interrupter 400 by wire or wirelessly.

Fig. 4 is a flowchart illustrating a counting method of the insect catching device 10 according to an embodiment of the present invention. As shown in fig. 1 and 4, the counting method of the insect catching device 10 includes steps 41 to 44 as follows. In step 41, the first photo interrupter 300 is photo-induced in the funnel element 200. In step 42, it is determined whether the first photo interrupter 300 senses a reflection of light in the funnel element 200, if so, go to step 43, otherwise, go back to step 41. In step 43, it is determined whether the intensity of the reflected light sensed by the first photo interrupter 300 is greater than a threshold (e.g., a predetermined value), if so, step 44 is performed, otherwise, the process returns to step 41. In step 44, the controller 500 is incremented, i.e., the current value is incremented by 1.

More specifically, there are several steps involved before step 43 as follows. When no object passes through the funnel element 200, the first photo interrupter 300 senses a first light value; when an object passes through the funnel member 200, the first photo interrupter 300 senses a second light value greater than the first light value; and setting the threshold between the first light value and the second light value.

Fig. 5 is a flow chart showing a counting method of the insect catching device 10 according to an embodiment of the present invention. As shown in fig. 1 and 5, the counting method includes steps 51 to 56 as follows. In step 51, the first photo interrupter 300 and the second photo interrupter 400 are photo-induced in the funnel element 200, and then step 52 and step 54 are performed. In step 52, it is determined whether the first photo interrupter 300 senses the reflection of an object (e.g., an insect) in the funnel element 200, if so, proceed to step 53, otherwise, go back to step 51. In step 53, it is determined whether the intensity of the reflected light sensed by the first photo interrupter 300 is greater than the threshold (e.g., a predetermined value), if so, step 54 is performed, otherwise, the process returns to step 51. In step 54, it is determined whether the second photo interrupter 400 senses the reflection of an object (e.g., an insect) in the funnel 200, if so, proceed to step 55, otherwise, go back to step 51. In step 55, it is determined whether the intensity of the reflected light sensed by the second photo interrupter 400 is greater than the threshold (e.g., a predetermined value), and then step 55 is performed. In step 56, when the light intensities of the reflected lights respectively sensed by the first photo interrupter 300 and the second photo interrupter 400 are both greater than the threshold (e.g., a predetermined value), the controller 500 performs a number accumulation, i.e., adds 1 to the current value.

In addition, in the embodiment, in order to prevent the light emission of the first photo interrupter 300 and the second photo interrupter 400 from interfering, the controller 500 controls the light emission timings (i.e., light emission sequences) of the first light emitting diode 320 and the second light emitting diode 420 to be staggered with each other, in other words, the first light emitting diode 320 emits light according to the first light emission timing; the second light emitting diode 420 emits light according to a second light emitting timing, which is different from the first light emitting timing, such that the first photodiode 330 and the second photodiode 430 can only receive the corresponding light reflection.

Thus, with the above-mentioned structure of the embodiments, the present invention can provide a more effective and precise solution for counting the total number of insects, so as to ensure that the pesticide spraying amount can accurately press the remaining insects.

Finally, the above-described embodiments are not intended to limit the invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention should be subject to the definition of the appended claims.
