Description

Termite detection device with a lure tension system

[0001] The present invention relates to a termite prediction device using a lure tensioning method, and more specifically, to a termite prediction device using a lure tensioning method that enables a manager to remotely check for the presence of termites without having to go to the site in person to check, thereby enabling a quick response.

[0002]

[0003] In general, it is known that there are about 2,050 species of termites living on Earth, and the termites living in Korea are Kyushu termites, which are about 2.3 mm long and are known to live in one house with about 10,000 to 100,000 of them.

[0004] Termites are social insects, and live in colonies consisting of king termites, queen termites, soldier termites, and worker termites.

[0005] Worker termites make up the majority of the termite population, and are known to forage for and bring food to feed larvae and soldier termites, raise young termites, serve soldiers, clean the house, repair damaged houses, and even build nests when the house needs to be moved.

[0006] Termites mostly eat wood and leaves, and also eat dead trees and fallen leaves, and obtain nutrition by breaking down fiber to absorb glucose, and produce excrement containing various organic substances and salts.

[0007] In this way, termites are essential insects in the ecosystem because they clean trees and fallen leaves and help plants grow well with their excrement, and they play an important role in connecting predators and producers in the ecological cycle.

[0008] However, important cultural properties made of wood, that is, wooden cultural properties, are becoming a major social problem as they are damaged by termites.

[0009] For example, at Tongdosa Temple in South Korea, out of the eight pillars measuring 50cm in diameter and 3m in height in the Yaksa Hall of Tongdosa Temple, five have already been reported to have been significantly damaged by termites. One pillar, which has had its base eaten away, is making a hollow sound even up to the point where you can touch it, and there is a hole between the foundation stone and the pillar that is large enough to fit a hand.

[0010] In addition, it has been reported that the Geungnakbojeon of Muwisa Temple in Jeollanam-do, the Daeungjeon of Seonunsa Temple in Jeollabuk-do, the Yeongsanjeon of Magoksa Temple in Chungcheongnam-do, the Daeungbojeon of Beopjusa Temple in Chungcheongbuk-do, the Geojoam Hermitage and Yeongsanjeon of Eunhaesa Temple in Gyeongsangbuk-do, the Geungnakjeon and Imcheonggak of Bongjeongsa Temple, the Muryangsujeon and Josadang of Buseoksa Temple in Gunjajeong, the Gaeksamun Gate and Haewunjeong Pavilion in Gangwon-do, and Ojukheon are all being damaged by termites.

[0011] According to the National Research Institute of Cultural Heritage's 2011 report on cultural property destruction by termites, out of 57 investigations of national treasures, treasures, and important folk cultural properties, damage was reported in 39 cases, resulting in a damage rate of 68.4%.

[0012] Termites like this were known to inhabit only parts of the Korean Peninsula, including South Chungcheong Province and the western region, in the 1920s. However, as the temperature of the Korean Peninsula rises along with global warming, the population of termites that prefer hot and humid environments is also rapidly increasing. A 2004 survey confirmed that they are evenly distributed across the country. The introduction of alien species is also increasing, making termite control a major social issue.

[0013] Methods for controlling termites in wooden cultural assets include fumigation, wood preservatives, soil treatment, and baiting.

[0014] Among them, the bait method is a pest control method that simultaneously destroys individuals and colonies by luring termites and making them consume toxic substances along with food, and has the advantage of causing less contamination of the soil and human body due to the chemicals.

[0015] This termite control method using the bait method is attracting attention due to its advantage of causing less contamination to the soil and human body, and is disclosed in Korean Patent Publication No. 1994-0006459 as a prior art applying the bait method.

[0016] However, the prior art disclosed in the above-mentioned public patent document Special Publication No. 1994-0006459 has a problem in that it is not efficient in detecting, predicting, or controlling termites because the bait station having a cartridge housed in a housing must be separated and observed every time in order to periodically investigate the activity of termites.

[0017] In addition, conventional termite capture or monitoring devices required managers to periodically visit the site and personally check the devices, which was a significant burden in terms of time and manpower, and there were many problems in terms of efficiency, such as cases where they were missed during inspection.

[0018] Therefore, a method to solve these problems is required.

[0019]

[0020] The present invention is an invention devised to solve the problems of the above-described prior art, and has the purpose of enabling accurate and efficient monitoring of termites by accurately detecting the presence or absence of termites and remotely transmitting a monitoring signal to a management server.

[0021] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0022]

[0023] In order to achieve the above object, the termite prediction device of the present invention, which uses a attractant tensioning method, comprises: a body having a hollow interior and having a passage hole formed therein for allowing termites to enter and exit; a cartridge unit accommodated inside the body and containing an attractant that serves as food for termites; a cover unit coupled to the upper end of the body to prevent foreign substances from entering the interior of the body and at the same time prevent termites that have entered the interior of the body from coming out indiscriminately; and a detection unit that is linked to the cartridge unit and detects when termites that have entered the interior of the body engage in feeding activities through the attractant to determine whether termites have entered. The cartridge unit is fixed in a state where the attractant is tensioned downward, and when the attractant is lost, at least a portion thereof moves upward and is detected by the detection unit.

[0024] In addition, the cartridge unit includes a fixed rod that is partially fitted into the interior of the body and has a hollow column shape, and has through holes formed on the upper and lower surfaces, an operating rod that has a predetermined length and is formed long in the up-and-down direction, and has a flange formed with an expanded upper cross-section so that the lower portion penetrates the through hole, an extension rod that is formed long and extends downward from the fixed rod and is inserted into the body together with the fixed rod, and an elastic body that is provided between the upper flange and the fixed rod and has its own elasticity so that the operating rod moves upward according to a change in the shape of the attractant, and the attractant has a predetermined length and is formed long, one end of which is fixed to the extension rod and the other end of which is connected to the operating rod, and when a change in shape occurs due to the feeding activity of termites, the operating rod can move upward along the longitudinal direction of the fixed rod.

[0025] In addition, the cartridge unit may further include a connecting rod whose upper end is fixed to the operating rod at a position adjacent to the fixed rod and moves up and down, and whose lower end is connected to the lure and is pulled downward.

[0026] In addition, the detection unit includes a magnetic sensor provided inside the cover unit and a magnet member provided on one side of the upper flange and capable of being linked to the magnetic sensor, and the magnetic sensor can detect a change in the magnetic field according to the displacement of the magnet member when the operating rod moves upward along the length direction due to the feeding activity of termites, thereby determining whether termites have entered.

[0027] In addition, the cover unit may further include a communication unit that receives a signal detected by the detection unit and transmits it to the management server.

[0028] In addition, when the above detection unit detects a change in the magnetic field from the magnetic sensor, it can transmit a signal of termite influx to the communication unit, thereby enabling remote monitoring from the management server.

[0029] In addition, a filler plate may be further included in the space between the body and the fixed rod among the internal spaces of the body to block the inflow of termites or termite excrement.

[0030] In addition, the above-mentioned lure is formed in the form of a sheet having a certain length, and a plurality of them can be arranged in a stacked form.

[0031] Additionally, the body is made of a material containing fiber, which can serve to attract termites.

[0032] In addition, the cover unit is equipped with a separate carbon dioxide exhaust means to expand the termite attraction range.

[0033]

[0034] The termite prediction device of the present invention, which uses an attractant tension method to solve the above-mentioned problem, has the following effects.

[0035] First, even if the manager does not go to the site regularly, the monitoring signal for termites can be transmitted remotely and checked in real time through the manager server, which has the advantage of enabling efficient monitoring without the burden of manpower and time.

[0036] Second, there is an advantage in that the presence of termites can be detected through sensors rather than directly by people, enabling accurate monitoring without missing anything.

[0037] The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

[0053] The present invention relates to a termite prediction device using a bait tensioning method that enables a manager to remotely check for the presence of termites without having to go to the site in person to check, thereby enabling a rapid response. The termite prediction device using a bait tensioning method is a device that can be installed in the ground at a predetermined interval around a wooden building or structure requiring protection, and monitors whether termites appear around the wooden building or structure requiring protection, and predicts this, thereby enabling a rapid response.

[0054] Referring to FIGS. 1 to 5 below, the configuration of a termite prediction device using a lure tensioning method according to the present invention is outlined as follows.

[0055] The termite prediction device of the attractant tension type according to the present invention comprises, as illustrated, a body (100) having a hollow interior to form a space and a passage hole (110) through which termites can enter, a cartridge unit (200) that can be accommodated inside the body (100) and includes an attractant (250) that serves as food for termites, a cover unit (300) that is detachably coupled to the upper end of the body (100) to prevent foreign substances from entering the interior of the body (100) and to prevent termites that have entered the interior of the body (100) from coming out indiscriminately, and a detection unit (400) that is connected to the cartridge unit (200) to detect when termites that have entered the interior of the body (100) engage in feeding activities through the attractant (250) and determine whether termites have entered.

[0056] And it can be formed by including a communication unit (500) provided inside the cover unit (300) to receive a signal detected by the detection unit (400) and transmit it to the management server (700).

[0057] The above body (100) is preferably formed in a rounded shape at the bottom or in a pointed shape due to its nature of being buried underground, and the overall external shape is also preferably formed in the shape of a cylinder, but is not limited thereto, and may be formed in the shape of a polygonal column such as a triangular column, a square column, or a pentagonal column.

[0058] In addition, the body (100) may be made of synthetic resin such as plastic or other various materials, but it is preferable to make it of a material containing fiber, for example, wood, so as to be more effective in attracting termites.

[0059] And termites have a habit of moving through space or creating a tunnel-shaped tube using termite excrement, etc. for protection when humidity is insufficient, and moving inside the tube. Therefore, it is preferable that the passage hole (110) formed in the body (100) to allow termites to enter the interior of the body (100) be formed as a circular hole so as to have a tube-like shape like a tunnel.

[0060] Meanwhile, the cover unit (300) can be attached to the upper part of the body (100) by any of a variety of methods, such as a fitting attachment, a fastening attachment, a white paper attachment, etc., or a method in which the upper part of the body (100) can be opened. This is to prevent foreign substances from entering the interior of the body (100) from outside, to prevent termites that have entered the interior of the body (100) from escaping indiscriminately, and to facilitate replacement and management of the cartridge unit (200) and the detection unit (400) accommodated inside the body (100).

[0061] The cover unit (300) has a plate-shaped structure that can simply cover the upper part of the body (100), and is configured to have a circumference that extends from the upper part of the body (100), and is preferably configured to have a structure that prevents termites that have entered the interior of the body (100) from moving and affecting the communication unit (500) and the detection unit (400), and forms an internal space that can accommodate the communication unit (500) and the detection unit (400) so that they are protected from external force.

[0062] In this embodiment, as shown in FIG. 2, the cover unit (300) can be positioned on the ground and exposed when the body (100) is inserted into the ground, and a part of the cover unit (300) can be configured to be openable, so that the communication unit (500) and the detection unit (400) can be easily replaced or inspected.

[0063] In addition, the cover unit (300) is equipped with a PCB board or battery inside to provide power for the detection unit (400) and the communication unit (500) to operate and control them at the same time.

[0064] Additionally, the cover unit (300) is equipped with a separate carbon dioxide exhaust means on the outside to expand the termite attraction range.

[0065] Specifically, the carbon dioxide discharge means is provided detachably inside or outside the cover unit (300) and is formed in a chamber shape to inject carbon dioxide contained inside into the surroundings.

[0066] At this time, termites tend to gather in places with high carbon dioxide concentrations, and this allows the carbon dioxide to be emitted over a wider area to attract termites.

[0067] Meanwhile, the cartridge unit (200) can be connected to the detection unit (400) described below, and includes the attractant (250) that serves as food for termites that enter the interior through the passage hole (110) formed in the body (100), so that the presence or absence of termites can be confirmed in the detection unit (400) by the attractant (250) being lost due to the feeding activity of termites and a part of it being raised or lowered.

[0068] Specifically, as illustrated in FIG. 4, the cartridge unit (200) includes a fixed rod (210) that can be fitted into the interior of the body (100), an operating rod (220) that is inserted into the fixed rod (210) and moves up and down, an extension rod (240) that is formed long and extends downward from the fixed rod (210), a connecting rod (230) that is configured independently of the extension rod (240) and is connected to the lower portion of the operating rod (220), and an elastic body (260) that provides elasticity to the operating rod (220).

[0069] The above fixed rod (210) is partially fitted into the interior of the body (100), and is formed in the shape of a hollow column, with through holes formed on the upper and lower surfaces, and the upper end is formed to be extended and joined to the cover unit (300).

[0070] And the above-mentioned operating rod (220) has a certain length and is formed long in the vertical direction, and an upper flange with an expanded upper cross-section is formed so that the lower part passes through the through hole and is configured to rise and fall in the vertical direction. At this time, the above-mentioned single body is provided between the operating rod (220) and the fixed rod (210), so that when the operating rod (220) moves downward, it is compressed and a restoring force is applied upward.

[0071] The above extension rod (240) is formed to extend downward from the above fixed rod (210) and is inserted into the inside of the main body together with the above fixed rod (210).

[0072] Specifically, the extension rod (240) has a bar shape that is formed long in the vertical direction, and the upper end is connected to the lower part of the fixed rod (210) and extends downward, and is inserted into the passage hole (110).

[0073] The above elastic body (260) is provided between the upper flange and the fixed rod (210) as a configuration that provides an external force so that the operating rod (220) can move upward as described above, and allows the operating rod (220) to move upward according to a change in the shape of the attracting body (250).

[0074] Meanwhile, the connecting rod (230) is positioned adjacent to the extension rod (240) at the bottom of the fixed rod (210), and the upper end is fixed to the operating rod (220) so that it moves up and down together, and the attracting body (250) is connected to the lower end so that it is pulled downward.

[0075] Specifically, as shown, the connecting rod (230) is positioned adjacent to the extension rod (240) at the bottom of the fixed rod (210), and the upper end is connected to the operating rod (220). At this time, the lower end of the connecting rod (230) is formed in a ring shape, and the attracting body (250) is coupled thereto, and the connecting rod (230) is fixed by being pulled downward by the attracting body (250).

[0076] And when the above-mentioned lure (250) is damaged by termite feeding, it moves upward together with the operating rod (220) due to the restoring force.

[0077] Here, the elastic body (260) is provided in a compressed state between the upper flange and the fixed rod (210), and when the attractant (250) is eaten away by the feeding activity of termites and gradually disappears, causing a change in shape, the lower side of the upper flange can be pushed up so that the operating rod (220) can move upward along the length direction of the fixed rod (210).

[0078] Meanwhile, the above-mentioned lure (250) has a certain length and is formed long, with one side fixed to the extension rod (240) and the other side connected to the operating rod (220), and when a change in shape occurs due to the feeding activity of termites, the operating rod (220) is moved upward along the length direction of the fixed rod (210).

[0079] In this embodiment, the lure (250) is formed in a sheet shape having a certain length, and is fixed in a state where a plurality of them are stacked and the other side is connected to the connecting rod (230) and the other side is pulled upward while touching the lowest end of the extension rod (240).

[0080] At this time, the lure (250) may be made of various materials containing fibers such as higher plants, cotton wool, filter paper, natural fiber, wood pulp, etc., and it is preferable to shape it using pulp, paper, or sawdust so that it can be relatively easily deformed according to the feeding activities of termites.

[0081] In addition, it is preferable that the other components of the cartridge unit (200) except for the attractant (250) be made of a material that does not contain fiber so that termites do not recognize them as food, thereby preventing any disruption in operation due to the consumption of the attractant (250).

[0082] The cartridge unit (200) configured in this manner is fixed in a state where the connecting rod (230) is pulled downward by the attractant (250), and when the attractant (250) is lost due to termite feeding, the operating rod (220) moves upward, and the detection unit (400) detects this.

[0083] Meanwhile, the detection unit (400) can be linked to the cartridge unit (200) to detect movement of the operating rod (220) according to a change in shape of the attractant (250), thereby detecting the presence or absence of termites.

[0084] Specifically, the detection unit (400) may be provided inside the cover unit (300), and may include a magnetic sensor (410) that can be connected to the communication unit (500), and a magnetic member (420) that is provided on one side of the upper flange and can be connected to the magnetic sensor (410).

[0085] Here, the magnetic member (420) moves together with the operating rod (220) as it moves upward, and the magnetic sensor (410) detects this and determines whether the operating rod (220) is operating.

[0086] Through this, the detection unit (400) can determine that termites have entered the body (100), and at this time, the magnetic sensor (410) can be connected to the communication unit (500), so that information on the entry of termites detected and determined by the detection unit (400) is converted into a signal and transmitted to the management server (700) through the communication unit (500), so that the manager can remotely detect the presence or absence of termites through the management server (700) without having to go to the site periodically and inspect each one in person.

[0087] In this way, the termite prediction device of the attractant tension type according to the present invention has an outer shape that is inserted into the ground and attracts termites, a cover unit (300) that is coupled to the upper part of the body (100) to block the inflow from the outside and accommodates the communication unit (500) and the detection unit (400), a cartridge unit (200) that partially operates when the attractant (250) is deformed or lost due to the inflow of termites inside the body (100), and a detection unit (400) that detects whether the cartridge unit (200) is operating, and when the detection unit (400) operates, a signal is transmitted from the outside from the communication unit (500) to detect whether termites occur.

[0088] Additionally, the termite prediction device of the attractant tension type according to the present invention may further include a filler plate (not shown) that is installed in an internal space formed in the body (100), and is positioned in a space corresponding to the upper portion of the attractant (250) among the spaces between the body (100) and the cartridge unit (200), so as to prevent termite excrement that feeds on the attractant (250) from flowing into the interior of the body (100) or termites from moving to the upper portion of the body (100).

[0089] Specifically, the filler plate has a cylindrical shape and is configured to surround at least a portion of the cartridge unit (200) and is inserted together into the body (100). At this time, it is possible to prevent termites from moving indiscriminately inside the body (100) by blocking termites from moving upwards, and also to prevent termite excrement from flowing into the upper portion of the body (100), thereby enabling the operating rod (220) to move smoothly along the fixed rod (210) without being fixed to the inner surface of the body (100) by organic matter, etc. contained in the termite excrement.

[0090] At this time, it is preferable that the filler plate is also made of a material that does not contain fibers, such as plastic or hard rubber, so that termites do not recognize it as food, similar to the material of the cartridge unit (200) other than the attractant (250).

[0091] Next, referring to FIG. 6, the operation process of the termite prediction device using a lure tension method according to the present invention will be examined as follows.

[0092] The termite prediction device of the attractant tension type according to the present invention detects a change in the position of the upper end of the operating rod (220) and detects this in the detection unit (400) when termites engage in feeding activities through the attractant (250), and as a result, a change in the shape of the attractant (250) occurs and the operating rod (220) moves upward along the fixed rod (210).

[0093] Specifically, looking at (a) of Fig. 6, the connecting rod (230) is pulled downward by the attracting body (250), and at the same time, the operating rod (220) moves downward, and the elastic body (260) is fixed in a compressed state.

[0094] At this time, the above-mentioned lure (250) is stably fixed while maintaining its circular shape without being damaged by termites.

[0095] And, as shown in (b) of Fig. 6, when termites that have entered the body (100) ingest the attractant (250) and the attractant (250) is damaged beyond a certain level, the attractant (250) is broken by the restoring force of the elastic body (260) and the connecting rod (230) and the operating rod (220) move upward.

[0096] At this time, the magnetic member (420) located at the upper part of the operating rod (220) also rises and falls, and accordingly, the magnetic sensor (410) detects this, and the corresponding information is transmitted to the management server (700) through the communication unit (500).

[0097] In this way, the termite prediction device of the attractant tension type according to the present invention is arranged in multiple units spaced apart from each other around the object to be protected and along the perimeter, and by independently detecting the presence or absence of termites from each device, it is possible to detect the presence or absence of termites and respond quickly accordingly.

[0098] Accordingly, even if the manager does not go to the site in person periodically, the monitoring signal for termites can be transmitted remotely and checked in real time through the manager server (700), which has the advantage of enabling efficient monitoring without the burden of manpower and time.

[0099] Additionally, there is an advantage in that the presence of termites can be detected through sensors rather than directly by people, allowing for accurate monitoring without missing anything.

[0100]

[0101] As described above, preferred embodiments of the present invention have been described. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms, in addition to the embodiments described above, without departing from the spirit or scope thereof. Therefore, the above-described embodiments should be considered illustrative rather than restrictive, and accordingly, the present invention is not limited to the above description, but may be modified within the scope of the appended claims and their equivalents.
