Description

Technical Field

[0001] This invention belongs to the field of biological detection technology, and in particular relates to a termite detection device and method based on photoelectric sensing technology. Background Technology

[0002] In order to maintain their own moisture and suitable activity temperature, termites will use soil, wood chips, or even termite corpses to make a covering for their activity area, mainly covering their movement paths and feeding areas. This covering is also called a mud blanket, so a mud blanket is an important feature for identifying termite activity.

[0003] Under current technology, conventional termite detection methods include manual inspection, which involves manually searching for signs of termite activity. However, this is inefficient and makes it difficult to provide early warnings of termite activity. In addition, methods such as termite sound detection, gas detection, and thermal imaging can be used. However, the detection equipment for these methods is expensive, and they are subject to high requirements for sound interference, gas interference, and other biological interference in the detection environment, resulting in poor detection accuracy. Summary of the Invention

[0004] This invention provides a termite detection device and method based on photoelectric sensing technology to solve the technical problem that conventional termite detection devices and methods under the existing technology cannot efficiently and accurately achieve termite detection and quantity prediction.

[0005] To solve the above problems, the technical solution of the present invention is: a termite detection device based on photoelectric sensing technology, comprising:

[0006] The detection box has an ant bridge and an ant bridge cover inside. The ant bridge and the ant bridge cover are spliced ​​together to form a detection chamber. The bottom surface of the ant bridge has several through holes for termites to enter or leave the detection chamber. The ant bridge cover is sealed to the ant bridge and is made of transparent material.

[0007] The termite guiding component extends along the length of the termite detection device and is used to be buried in the area to be tested to attract termites to eat. The termite guiding component has several guiding channels inside, and the top openings of the several guiding channels are sequentially connected to several through holes on the bottom surface of the termite bridge.

[0008] A photoelectric detection component is used to detect changes in light intensity transmitted through the termite bridge cover inside the detection chamber after termite activity, and to calculate termite activity intensity data based on the changes in light intensity.

[0009] Preferably, the termite guiding component includes a plurality of bait sticks and a plurality of guiding sticks, wherein the bait sticks are disposed on the outer periphery of the guiding sticks, and the bait sticks and the guiding sticks are arranged side by side in the same direction;

[0010] The guide rod has a guide channel inside, which is coaxially arranged with the guide rod and extends through the top of the guide rod at only one end.

[0011] Preferably, the bait stick and guide stick are made of pine or eucalyptus wood.

[0012] Preferably, the photoelectric detection component includes a light source group and a photoelectric sensor. The light source group is located at the circumferential edge of the detection chamber or the bottom surface of the ant bridge. The light source output by the light source group faces the first side of the ant bridge cover plate.

[0013] The photoelectric sensor is located on the top of the detection box, and the light source receiving end of the photoelectric sensor faces the second side of the ant bridge cover.

[0014] The photoelectric detection component is configured such that the photoelectric sensor receives light output from the light source group that penetrates the ant bridge cover and converts the light signal into an electrical signal. When the activity intensity of termites in the detection chamber increases, the amount of mud formed on the surface of the ant bridge cover increases, and the electrical signal output by the photoelectric sensor weakens accordingly.

[0015] Preferably, the termite detection device based on photoelectric sensing technology also includes a main control box, which is equipped with a main control module and a communication module for the photoelectric detection component. The main control module is used to control the light output intensity of the light source group, receive the electrical signals output by the photoelectric sensor, and analyze the termite situation.

[0016] The communication module is wirelessly connected to the cloud server and is used to output ant population data to the cloud server.

[0017] Preferably, the main control box is also equipped with an independent power supply, which is used to continuously power the photoelectric detection component.

[0018] Preferably, the termite detection device based on photoelectric sensing technology further includes a housing, which is fitted over the detection box and the termite guiding component. The housing has several holes and slits in the horizontal circumference of the termite guiding component for termites to enter and exit.

[0019] Preferably, the height of the detection chamber is 1-10 mm.

[0020] Preferably, the detection box is made of an opaque metal material.

[0021] Based on the same concept, the present invention also provides a termite detection method based on photoelectric sensing technology, applied to a termite detection device based on photoelectric sensing technology as described in any one of the above, comprising the following steps:

[0022] S1: Completely bury one end of the termite guiding component of the termite detection device into the area to be tested;

[0023] S2: Control the light source component to output the light source, the photoelectric sensor receives the light source, and generates a detection electrical signal En based on the light intensity. The detection electrical signal En is compared with the preset threshold electrical signal Eb. When the detection electrical signal En is greater than the threshold electrical signal Eb, it is determined that mud has formed in the ant bridge cover and termite activity exists in the area to be tested.

[0024] S3: Based on the change amplitude of the detected electrical signal En within a unit of time, estimate the number of termites present in the area to be tested.

[0025] Because the present invention adopts the above technical solution, it has the following advantages and positive effects compared with the prior art:

[0026] This invention provides a termite detection device and method based on photoelectric sensing technology. The termite detection device includes a detection box, a termite guiding component, and a photoelectric detection component. The detection box contains a detection chamber. When termites are attracted into the detection chamber by the termite guiding component, they form a mud blanket on the inner wall of the chamber. The greater the termite activity, the thicker the mud blanket and the shorter the formation time. By detecting the light transmittance of the termite bridge cover using the photoelectric detection component, the presence of termite activity inside the detection chamber can be indirectly determined, and the number of termites in the test area can be estimated. Therefore, this invention enables automated detection of termite activity intensity. Furthermore, based on photoelectric sensing technology, the environmental requirements for the termite detection device are relatively low, and the detection accuracy is high, facilitating early warning of termites.

Detailed Implementation

[0033] The termite detection device and method based on photoelectric sensing technology proposed in this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this invention will become clearer from the following description and claims.

[0034] First Embodiment

[0035] See Figures 1-5 This embodiment provides a termite detection device based on photoelectric sensing technology, which is used to realize the automated detection function of termite activity intensity. The main structure includes a detection box 1, a termite guiding component and a photoelectric detection component.

[0036] See Figures 1-3 The detection box 1 is equipped with an ant bridge 2 and an ant bridge cover 3 inside. The ant bridge 2 is a structural design specifically designed to attract termites to a designated area. In this embodiment, the ant bridge 2 and the ant bridge cover 3 can be spliced ​​together. After the splicing is completed, a detection chamber 13 will be formed inside the overall structure. Several through holes 4 are provided on the bottom surface of the ant bridge 2 for termites to enter or leave the detection chamber 13. The ant bridge cover 3 and the ant bridge 2 are sealed together, that is, the detection chamber 13 is a relatively closed structure, and termites can only enter the interior of the detection chamber 13 through several through holes 4.

[0037] Furthermore, the ant bridge cover 3 is made of transparent material.

[0038] The termite guiding component extends along the length of the termite detection device and is used to attract termites by burying it in the area to be tested. The termite guiding component has several guiding channels 5 inside, and the top openings of the guiding channels 5 are sequentially connected to several through holes 4 on the bottom surface of the termite bridge 2. In this embodiment, when the termite guiding component is buried in the area to be tested, it attracts termites. After the termites enter the guiding channels 5, they will further enter the detection chamber 13 along the guiding channels 5, and re-enter different guiding channels 5 from inside the detection chamber 13 through different through holes 4. Based on the living habits of termites, in order to maintain their moisture and suitable activity temperature, termites will use soil, sawdust, or even termite corpses to create a covering material to cover their activity area, mainly covering their movement path and feeding area. This covering material is also called a mud blanket. Therefore, in this embodiment, if termites are present in the area to be tested, after the termites are attracted into the detection chamber 13 by the termite guiding component, they will inevitably form a mud blanket on the inner wall of the detection chamber 13. (See reference...) Figure 4 .

[0039] The photoelectric detection component is used to detect changes in light intensity through the transparent termite bridge cover 3 inside the detection chamber 13 after termite activity, and to calculate the termite activity intensity based on the light intensity change data. In this embodiment, if termite activity exists in the detection chamber 13, there will inevitably be mud on the bottom surface of the termite bridge cover 3, and the thickness and formation rate of the mud are directly proportional to the termite activity intensity. The photoelectric detection component can detect the light transmittance of the transparent termite bridge cover 3, and indirectly determine the thickness and formation rate of the mud based on the light transmittance, thereby determining whether termite activity exists in the test area and estimating the number of termites in the test area based on experience.

[0040] In summary, this embodiment provides a termite detection device based on photoelectric sensing technology. By utilizing the characteristic that termites form mud blankets during their activities and photoelectric sensing technology, it achieves automated detection of termite activity intensity. Furthermore, photoelectric sensing technology has low requirements for the applicable environment of the termite detection device, has high detection accuracy, and helps to realize the early warning function of termites.

[0041] The specific structure and function of the termite detection device based on photoelectric sensing technology provided in this embodiment will be described in further detail below:

[0042] Preferably, in this embodiment, the termite guiding component includes a plurality of bait sticks 6 and a plurality of guiding rods 7. The bait sticks 6 are disposed on the outer periphery of the guiding rods 7, and the bait sticks 6 and the guiding rods 7 are arranged side by side in the same direction to attract termites to gnaw on them.

[0043] The guide rod 7 has a guide channel 5 arranged coaxially with the guide rod 7 and only one end of the guide rod 7 passes through the top of the guide rod 7. That is, the guide channel 5 is not connected at the bottom inside the guide rod 7. One end of the guide channel 5 extends to the middle section of the guide rod 7, and the other end of the guide channel 5 extends through the top of the guide rod 7, forming an opening at the top of the guide rod 7. The opening at the top of the guide rod 7 is connected to the through hole 4 on the bottom surface of the ant bridge 2.

[0044] In this embodiment, after the termite guiding component attracts termites, the termites will first gnaw on the outer bait rod 6, and then gnaw on the inner guiding rod 7. After the termites gnaw through the guiding rod 7 and enter the guiding channel 5, they will enter the detection chamber 13 along the extension direction of the guiding channel 5, and will further re-enter the different guiding rods 7 into the guiding channels 5 from the inside of the detection chamber 13 through different through holes 4.

[0045] By setting up the guide channel 5, termites can be guided to move along a predetermined route, which helps to facilitate the smooth progress of subsequent mud cover formation and monitoring. Compared with open termite trapping methods, the termite guiding component provided in this embodiment uses the relatively closed guide channel 5 and detection chamber 13 to reduce the impact of external environmental factors (such as weather changes, interference from other animals, etc.) on termite behavior and mud cover formation, ensuring the stability and reliability of data detection.

[0046] Specifically, in this embodiment, both the bait stick 6 and the guide stick 7 are made of wood that termites like to eat, such as pine or eucalyptus, to increase their attractiveness to termites.

[0047] Preferably, in this embodiment, the photoelectric detection component includes a light source group 8 and a photoelectric sensor 9. The light source group 8 can be disposed on the circumferential edge of the detection chamber 13 or on the bottom surface of the ant bridge 2. The light source output by the light source group 8 faces the first side of the ant bridge cover plate 3. The photoelectric sensor 9 is disposed on the top of the detection box 1. The light source receiving end of the photoelectric sensor 9 faces the second side of the ant bridge cover plate 3, wherein the first side and the second side of the ant bridge cover plate 3 refer to the lower surface and the upper surface of the horizontally placed ant bridge cover plate 3, respectively.

[0048] In this embodiment, when the light source group 8 is activated, it outputs light towards the ant bridge cover plate 3. When there are no foreign objects covering the surface of the ant bridge cover plate 3, the light can penetrate the ant bridge cover plate 3, and the photoelectric sensor 9 can receive the light that penetrates the ant bridge cover plate 3 and convert the light signal into an electrical signal for output. When termites are present inside the detection chamber 13 and the intensity of termite activity increases, a mud cover will gradually form on the surface of the ant bridge cover plate 3. The light is blocked by the mud cover, and the light received by the photoelectric sensor 9 that penetrates the ant bridge cover plate 3 is weakened. Therefore, the electrical signal output by the photoelectric sensor 9 is correspondingly weakened. By obtaining the electrical signal output by the photoelectric sensor 9, it can be determined that there is termite activity in the area to be tested, and the number of termites in the area to be tested can be further estimated.

[0049] Specifically, in this embodiment, the photoelectric detection component also includes a main control module and a communication module. The termite detection device also includes a main control box 10. The main control module and communication module of the photoelectric detection component are located inside the main control box 10. The main control module is used to control the light output intensity of the light source group 8, receive the electrical signals output by the photoelectric sensor 9, and analyze the termite infestation. The communication module is wirelessly connected to the cloud server and is used to output termite infestation data to the cloud server, realizing the data upload function.

[0050] In one embodiment, see Figure 5The main control module includes a photoelectric detection circuit, and the photoelectric sensor 9 is a photoresistor Rn whose resistance can be adjusted based on the intensity of the received light. The resistance of the photoresistor Rn changes with the light intensity; that is, the stronger the light, the lower the resistance, and the weaker the light, the higher the resistance. A fixed resistor R0 is also included in the photoelectric detection circuit. The photoresistor Rn and the fixed resistor R0 are connected in series, and the common connection point of the photoresistor Rn and the fixed resistor R0 is the output terminal of the photoelectric detection circuit. The output terminal of the photoelectric detection circuit is equipped with an analog-to-digital converter (ADC) to convert the analog voltage signal into a digital signal for output.

[0051] Specifically, the calculation method for reading the detection signal En on the photoresistor Rn via the analog-to-digital converter (ADC) is as follows:

[0052] En = Rn / (R0 + Rn) * N

[0053] Where N is the mapping range of the analog-to-digital converter (ADC), i.e., the maximum output value.

[0054] When there is no mud inside the detection chamber 13, the light can completely penetrate the ant bridge cover 3, and the brightness is the highest. At this time, the resistance of the photoresistor Rn is the minimum value Rmin, and the detection signal En is read as the minimum value Emin. When the detection chamber 13 is completely covered by mud, the light is completely blocked by the mud in the ant bridge cover 3, and the brightness is the lowest. At this time, the resistance of the photoresistor Rn is the maximum value Rmax, and the detection signal En is read as the maximum value Emax. Therefore, in this embodiment, the value range of En is [Emin, Emax].

[0055] Based on extensive experimental findings, a threshold electrical signal Eb can be preset. When the detected electrical signal En is less than the threshold signal Eb, it is determined that there is temporarily no termite activity in the detection chamber 13. When the detected electrical signal En is greater than the threshold signal Eb, it proves that there is mud inside the detection chamber 13, and it is determined that there is termite activity in the detection chamber 13.

[0056]

[0057] Preferably, in this embodiment, the main control box 10 is also equipped with an independent power supply. The independent power supply is used to continuously power the photoelectric detection component. The independent power supply ensures that the photoelectric detection component is not limited by the external power supply, so as to realize continuous and uninterrupted monitoring of termite activities and realize the early warning function of termite activity.

[0058] In another embodiment, if long-term monitoring of the area under test is required, the operating mode of the photoelectric detection component can be set to intermittent automatic start and stop to reduce power consumption.

[0059] Preferably, in this embodiment, the termite detection device further includes a housing 11, which is fitted over the detection box 1 and the termite guiding component. The housing 11 has several holes 12 in the horizontal circumferential direction of the termite guiding component for termites to enter and exit. The housing 11 protects the detection box 1 and the termite guiding component from damage and contamination during storage, transportation, deployment, and daily operation, ensuring stable long-term operation. Furthermore, the size of the holes 12 in the housing 11 is adapted to the size of the termites, effectively guiding them into the termite guiding component from a specific location while preventing other non-target organisms or larger objects from entering, thus improving detection accuracy.

[0060] Preferably, in this embodiment, the height of the detection chamber 13 is set to 1-10 mm. A detection chamber 13 with a height in the range of 1-10 mm can ensure that the target termites can smoothly enter the detection chamber 13 and move freely, while restricting the entry of larger organisms or non-target objects, thereby improving the accuracy of detection. Moreover, the detection chamber 13, which has a limited height but a large horizontal area, makes it easier for termites to form a mud blanket on the surface of the termite bridge cover 3, thereby improving the sensitivity of detection.

[0061] Preferably, in this embodiment, the detection box 1 is made of opaque metal material and has a relatively closed structure with no other openings on its outer surface, thereby preventing external light from affecting the operation of the photoelectric detection component and preventing biological organisms from entering the detection box 1, thus improving the accuracy of the detection results.

[0062] Second Embodiment

[0063] Based on the same concept, the present invention also provides a termite detection method based on photoelectric sensing technology, applied to a termite detection device based on photoelectric sensing technology as described in any one of the first embodiments, comprising the following steps:

[0064] S1: Completely bury one end of the termite guide component of the termite detection device in the area to be tested, such as in the soil.

[0065] S2: The main control module of the photoelectric detection component controls the light source component to output a light source of a specific brightness. Then, the photoelectric sensor 9 receives the light source and generates a detection electrical signal En based on the light intensity. The main control module compares the detection electrical signal En with the preset threshold electrical signal Eb. When the detection electrical signal En is greater than the threshold electrical signal Eb, it is determined that mud has formed in the ant bridge cover 3, that is, there is termite activity in the area to be tested.

[0066] S3: Based on the change amplitude of the detected electrical signal En within a unit of time, estimate the number of termites present in the area to be tested.

[0067] Furthermore, the communication module of the photoelectric detection component uploads the termite detection results to the cloud server. When termite activity is detected in the area to be tested, the cloud server outputs an alarm.

[0068] In summary, this embodiment provides a termite detection method based on photoelectric sensing technology, which realizes automated real-time detection of termite activity in the area to be tested without human intervention, effectively improving detection efficiency. Furthermore, based on photoelectric sensing technology, it effectively enhances the accuracy and reliability of the detection data.
