Description

Technical Field

[0001] The invention relates to termite detection, and in particular to a termite detection device. Background Art

[0002] Termites are one of the five major pests in the world. Although they are small, their harm involves almost every field of the national economy. People's clothing, food, housing, transportation and daily necessities are all harmed by them. The harm to houses, reservoir dams, mountain forests and orchards, communication equipment, etc. is particularly serious. Termites damage objects in a hidden way and are not easy to be discovered. The surface of the damaged objects looks intact, but the inside is full of holes. Once discovered, it has caused significant losses, especially in some scenic spots, historical sites, important cultural relics and other areas, which need to be monitored and managed.

[0003] The existing termite monitoring system has the following problems: 1) The current traditional termite monitoring requires personnel to conduct on-site inspections, which is time-sensitive and requires the staff to have high professional and technical capabilities, and cannot achieve timely detection of termite infestations; at the same time, the lag in the traditional early warning method has caused major hidden dangers in water conservancy projects including river embankments, which is not conducive to subsequent treatment;

[0004] 2) Usually termite detection devices are buried underground, and termites like to live in a humid environment, so the detection environment is usually also a humid environment. In this case, the detector or detector is easily contaminated, and the existing detection device does not have a stable termite source, resulting in low detection accuracy. Summary of the invention

[0005] In response to the above technical problems, the present invention provides a termite detection device, in which a detection unit is arranged in a relatively closed cavity to prevent the detection unit from being contaminated. The cavity is connected through deep holes on the bait strip, and termites enter the cavity through the deep holes, forming a stable source of termites. In addition, the arrangement of the detection unit and the circuit board can also transmit data wirelessly to a cloud server, thereby realizing the solution that does not require personnel to conduct on-site inspections.

[0006] To achieve the above object, the technical solution of the present invention is:

[0007] A termite detection device, comprising a plurality of bait strips that termites like to eat, a detection unit and a circuit board, wherein the bait strip has a deep hole with a bottom that is blocked along its axial direction, a detection box is installed on the upper part of the bait strip, the detection box has a cavity inside, the cavity is connected to the deep hole, the detection unit is arranged in the inner cavity of the detection box, and the detection unit is electrically connected to the circuit board;

[0008] After termites eat the bait strips, they enter the cavity through the deep hole. The detection unit is configured to detect whether there are termites in the inner cavity. The circuit board is configured to collect detection data of the detection unit and send the detection data to a cloud server.

[0009] Preferably, the detection unit is a capacitive sensing sheet, and at least one of the capacitive sensing sheets is arranged on the upper wall of the inner cavity;

[0010] The termites form a mud blanket in the cavity, and the mud blanket or the termites touch the capacitive sensing sheet, and the capacitive sensing sheet generates capacitance.

[0011] Preferably, the height of the cavity is 2-3 cm.

[0012] Preferably, the capacitive sensing sheet is fixed to the upper wall of the inner cavity by epoxy resin glue.

[0013] Preferably, the circuit board includes a communication module and a main control module, the communication module is electrically connected to the active module, the main control module is configured to collect detection data of the detection unit, and the communication module is configured to send the detection data to a cloud server.

[0014] Preferably, the main control module is also configured to start and stop the detection device at a scheduled time.

[0015] Preferably, it further comprises a main control box, and the circuit board is arranged in the main control box.

[0016] Preferably, it also includes a base, which is fixed to the bottom of the bait strip.

[0017] Preferably, it further comprises a support column, the bottom of which is fixed on the base, and the upper part of which passes through the detection box and is fixedly connected to the main control box.

[0018] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art:

[0019] The present invention sets deep holes along the axial direction of the bait strip that termites like to eat, and sets a detection box on the bait strip. The detection box has a cavity, which is only connected to the deep hole, so the cavity is a closed space. The detection unit is set in the cavity, so that the detection unit is not polluted by the outside world; and because the deep hole is set, after the termites bite the bait strip, the termites can enter the cavity through the deep hole, forming a special "ant bridge structure", and establishing a semi-enclosed space for termite activities. The active group of termites will continue to move in the space of the ant bridge, and maintain an environment (such as temperature and humidity) inside the ant bridge that meets the survival of termites. The ant bridge structure realizes the gathering environment of termites, shields the invasion of other non-termite species, and will not detect non-termite living bodies, greatly improving the accuracy of detection.

[0020] The detection device of the present invention is also provided with a circuit board, so that the detection unit is electrically connected to the circuit board. When the detection unit detects that there are living termites or termites in the cavity, the circuit board collects the detection data of the detection unit and sends the data to the cloud server, thereby achieving the elimination of the need for manual on-site inspection. As long as the detection unit detects living termites or termites, the circuit board can transmit the data to the cloud server, and at this time, it can be known that there are a large number of termites in a certain place, and prevention can be carried out immediately. Therefore, the timeliness of the detection is guaranteed.

[0021] In a preferred embodiment of the present invention, the detection unit is preferably a capacitive sensing sheet. Due to the habit of termites themselves, and when termites gather in the cavity, they will carry soil into the cavity, and a mud blanket is formed by mixing soil, termite saliva and feces. The mud blanket has a certain humidity and air permeability, and can maintain a stable environment for termites to survive. Once the mud blanket reaches a certain height and touches the capacitive sensing sheet, the capacitive sensing sheet generates a capacitance change signal, and the capacitive sensing sheet is electrically connected to the circuit board. After the circuit board collects the signal of the capacitive sensing sheet, it sends it to the cloud server to realize automatic detection of termites. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention studies the living habits of termites, sets deep holes in the bait strip, and sets a closed detection box on the bait strip. The detection box has a closed cavity, and the cavity is connected to the deep hole to form an ant bridge structure, which is used to provide a semi-enclosed space for termite activities. In the space of the ant bridge, the colony of living termites keeps moving in the ant bridge structure, and keeps the inside of the ant bridge in a gathering environment that is suitable for termite survival. Therefore, the present invention sets a deep hole and a cavity enclosed space. Under normal circumstances, the detection unit is in a closed space and is not polluted by the outside world; after the termites gnaw the bait strip, the structure of the deep hole and the cavity provides an ant bridge structure that is suitable for termite gathering, so that the detection structure is more accurate.

[0029] The following is a further detailed description of a termite detection device proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description.

[0030] See also Figure 1-5 A termite detection device, comprising a plurality of bait strips 1 that termites like to eat, a detection unit and a circuit board, wherein the bait strip 1 has a deep hole 2 with a bottom that is blocked along its axial direction, a detection box 3 is installed on the upper part of the bait strip 1, and the detection box 3 has a cavity inside, and the cavity is connected to the deep hole 2, the detection unit is arranged in the inner cavity of the detection box 3, and the detection unit is electrically connected to the circuit board;

[0031] Under normal circumstances, the cavity provides a safe and pollution-free environment for the detection unit, and protects the detection unit in the absence of termites;

[0032] In the case of termites, after the termites gnaw the bait strip 1, they enter the cavity through the deep hole 2. The detection unit is configured to detect whether there are termites in the inner cavity. The circuit board is configured to collect detection data of the detection unit and send the detection data to the cloud server.

[0033] In this embodiment, a deep hole 2 is set along the axial direction of the bait strip 1 that termites like to eat, and a detection box 3 is set on the bait strip 1. The detection box 3 has a cavity, which is only connected to the deep hole 2, so the cavity is a closed space. The detection unit is set in the cavity, so that the detection unit is not polluted by the outside world; and because the deep hole 2 is set, after the termites bite the bait strip 1, they usually bite through part of the bait strip 1 first, enter the cavity through the deep hole 2 inside the bait strip 1 that was bitten through first, and move in the inner cavity. At the same time, they will also gnaw other bait strips 1 through the cavity. Since the inner cavity and the deep hole 2 form a relatively closed structure, it becomes a stable activity path for termites, forming a special "ant bridge structure", establishing a semi-enclosed space for termite activities, and the termite activity group will continue to maintain stable activities in the space of the ant bridge, and maintain an environment (such as temperature and humidity) inside the ant bridge that is suitable for termite survival. The ant bridge structure realizes a gathering environment for termites, shields the invasion of other non-termite species, and will not detect non-termite living bodies, greatly improving the accuracy of detection.

[0034] In specific implementation, deep holes can be set in some bait strips, and there is no need to set bait strips in all bait strips.

[0035] In one preferred embodiment, the detection unit is a capacitive sensing sheet 4, at least one of the capacitive sensing sheets 4 is arranged on the upper wall in the cavity, that is, the detection box 3 includes a detection cover 301 and a detection box body 302, the detection cover 301 and the detection box body 302 form a closed cavity, and the capacitive sensing sheet 4 is arranged on the detection cover 301, and is arranged on a side of the detection cover 301 located in the cavity;

[0036] The termites form a mud blanket in the cavity, and the mud blanket or the termites touch the capacitive sensing sheet 4, so that the capacitive sensing sheet 4 generates capacitance.

[0037] In this embodiment, due to the formation of an ant bridge structure, due to the habit of termites themselves, and when termites gather in the cavity, termites will carry soil into the cavity, and a mud blanket is formed by mixing soil, termite saliva and feces. The mud blanket has a certain humidity and air permeability, and can maintain a stable environment for termites to survive. Once the mud blanket reaches a certain height and touches the capacitive sensing sheet 4, the capacitive sensing sheet 4 generates a capacitance change signal, and the capacitive sensing sheet 4 is electrically connected to the circuit board. After the circuit board collects the signal of the capacitive sensing sheet 4, it sends it to the cloud server to realize automatic detection of termites.

[0038] Since the capacitive sensing sheet 4 is sensitive to touch, the ant bridge structure provides protection for the normal operation of the capacitive sensing sheet 4. Without the protection of the ant bridge structure, the capacitive sensing sheet 4 will be induced by the invasion of external non-termite factors (such as water drops, soil, etc.) and will not be able to work normally. However, the ant bridge structure provides an environment and space for termites to gather, so that an ant blanket can be formed. Once the ant blanket approaches the capacitive sensing sheet 4, the capacitive sensing sheet 4 produces a capacitance change, and the circuit board can collect the corresponding signal of the capacitive sensing sheet 4, thereby determining the presence of termites.

[0039] Further preferably, the height of the cavity is 2-3 cm. Due to the height of the anthill formed by the gathering of termites, in order to allow the living termites to be very close to the capacitive sensing sheet 4 in the cavity, the height of the cavity needs to be controlled.

[0040] Further preferably, the capacitive sensing sheet 4 is fixed on the detection cover 301 by epoxy resin glue.

[0041] In some other embodiments, the circuit board includes a communication module and a main control module, the communication module is electrically connected to the active module, the main control module is configured to collect detection data of the detection unit, and the communication module is configured to send the detection data to a cloud server.

[0042] The communication module and the main control module are concentrated on the circuit board. The main control module collects the sensing signal of the capacitive sensing sheet 4, and the communication module sends the sensing signal to the cloud server by wireless means. The cloud server can be provided with an alarm module. Once the cloud server receives the signal of the detection device, it can immediately check and repair the buried location of the detection device, thus realizing automatic detection.

[0043] Preferably, the main control module is also configured to start and stop the detection device at a scheduled time to achieve the purpose of low power consumption.

[0044] Preferably, it further comprises a main control box 7, and the circuit board is arranged in the main control box 7 to protect the circuit board.

[0045] In order to fix the bait strip 1 , the detection device further comprises a base 5 , wherein the base 5 is fixed to the bottom of the bait strip 1 , and the detection box 3 is fixed to the upper part of the bait strip 1 .

[0046] Preferably, it further comprises a support column 6 , the bottom of which is fixed on the base 5 , and the upper part of which passes through the detection box 3 and is fixedly connected to the main control box 7 .

[0047] Usually, the support column 6 is set at the center of the entire detection device, and multiple bait strips 1 are arranged around the support column 6. The support column 6 passes through the detection box 3 and is connected to the main control box 7, so that the bait strips 1 are exposed to the outside of the entire detection device to attract termites. The bait strips 1 are fixed, and the bait strips 1 in the detection box 3 can be connected to the circuit board in the main control box 7 via wires.

[0048] The working principle of this embodiment is:

[0049] The detection device is buried underground. Under normal circumstances, the detection box 3 and the main control box 7 protect the electrical components of the detection device from being affected by the external humid environment.

[0050] In the presence of termites, the termites gnaw on the bait strip 1, and after biting through the deep hole 2, the termites enter the cavity through the deep hole 2 to form an ant bridge structure, and a termite mud blanket is formed in the cavity. The mud blanket or the living bodies of the termites touch the capacitive sensing sheet 4, and the capacitance of the capacitive sensing sheet 4 changes. The main control module collects the signal of the capacitive sensing sheet 4, and the communication module sends the signal collected by the main control module to the cloud server via wireless mode, thereby realizing automatic detection of termites.

[0051] This embodiment is based on the ant bridge structure, and the capacitive sensing sheet 4 and the ant bridge structure are designed in an integrated manner. The ant bridge structure realizes the termite gathering environment. When termites gather, the living termite colony is large in number, forming a target that can be detected by capacitive sensing, so that the capacitive sensing based on biological living bodies can smoothly sense the existence of termites. The ant bridge structure itself, due to its characteristics that conform to the behavior of termites, shields the invasion of other non-termite species, and will not sense non-termite living bodies, greatly improving the accuracy of detection. It makes termite detection based on capacitive sensing possible.

[0052] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
