Description

The present invention relates to a long-life pest detection and extermination device and a management system when the pest detection and extermination device is installed over a wide area.

Termites are regarded as pests because they attack mainly wood and buildings, and depending on the degree of damage, they may make buildings unusable. Pest control measures are also being promoted, and chemical spraying-type measures such as the barrier construction method have been used for a long time. Agents used in the barrier construction method, such as pyrethrod-based neonicotinoids, are said to be effective for a long period of time and to be highly safe, but they have adverse effects on people with allergies, hypersensitivity to chemicals, and pets. cases have also been reported. In Japan, there are many excellent wooden buildings such as shrines, temples and castles. Many of these buildings are managed as important cultural properties and are visited by many worshipers and tourists. Therefore, it is a big problem that the influence on humans cannot be completely ignored.

In addition, although the chemicals used in the barrier construction method have immediate effects, it is almost impossible to eradicate nests that are home to termites. The bait construction method improved this point. A chemical that inhibits the molting of termites is planted in the anthills that termites pass through and in areas that have been damaged by feeding. Then, by causing the termites that have ingested the drug to return to the nest, the drug spreads throughout the termites belonging to the nest. Since termite colonies that are unable to molt will sooner or later die out, it is possible to destroy the entire colony by installing poisonous baits. The total amount of chemicals used in the bait method is less than 1/1000th of that in the barrier method, and since it affects only molting organisms, there is no effect on humans, pets such as cats and dogs, birds and plants. .

In order to make the termites bring back the medicine before they reach the building, it is necessary to plant poisonous baits between the ground where the termites live and the building, that is, in the ground. For this purpose, an embedded poison bait installation machine has been developed, and for example, Patent Documents 1 to 3 are disclosed.

Patent Document 1 discloses a termite detection device and a termite detection device provided with a gas sensor for detecting a detection target gas, which is surrounded by a film material eaten by termites, and a gas sensor for detecting the detection target gas. A system capable of wirelessly communicating the detection status of is described. In Patent Document 2, when a termite eats a core material, a shielding plate is moved by the force of a spring, and as a result, a light-emitting element and a light-receiving element of a photodetector are cut off, thereby detecting and transmitting a signal. Techniques are disclosed. Patent Literature 3 discloses a technique for detecting metabolic gases generated when termites eat wood and transmitting signals wirelessly.

However, the inventions described in Patent Documents 1 to 3 all lack the perspective of large-scale facilities such as shrines, temples, and castles, that is, laying a large number of detection devices over a wide area and making them function as a termite detection system over a period of several years. . In the technique described in Patent Document 1, it is necessary to enclose the emission that emits the detection target gas in the artificial bait, but the gas sensor is easily affected by temperature and humidity, and high cost is required to ensure stable operation. It is necessary and costly to manufacture the emissions. Patent Document 2 requires both a light-sensing element and a light-emitting element, which is not only disadvantageous in terms of cost, but also lacks the viewpoint of power saving because it assumes continuous sensing of light. Furthermore, since the springs do not operate unless termites eat a specific part of the core material, there is a possibility that the building body will already be damaged when they operate. Patent Document 3 assumes detection of gases such as hydrogen gas, which requires high cost.

Therefore, although the systems described in these documents can be applied to a general residential level, they cannot be used for termite countermeasures in large-scale buildings, wide-ranging roadside trees, and green belts that require large-scale burial over a wide area. However, there is a problem in terms of cost.

In addition, large buildings, which often serve as tourist destinations, also require downtime to be as short as possible. More specifically, once installed, it is preferable that the function is exhibited continuously for at least several years, and if possible, for about five years. Durability, reliability, power saving, etc. are required, but no pest detection and extermination device equipped with these or a system that operates these devices in an integrated manner has not yet been provided.

Accordingly, the present invention provides a pest detection and extermination apparatus and system that can monitor the condition of termite inhabitation in the ground and has wireless notification means.

The pest detection and extermination device of the present invention employs a system that presses the bait with a sensing wire from the side of the bait, unlike the conventional system that assumes gas detection or light detection. When eaten, the bait rotates without being able to withstand the pressure of the sensing wire, the sensing wire is pushed toward the bait, and the movement is detected. Therefore, even when a small amount of termites eat any part of the bait, they can be made to move reliably.

Not only does it require no expensive gas-filled membrane or high power, but it can be expected to operate for about five years. Therefore, it is possible to keep the total cost of installing a large number of pest detection and extermination devices low, lengthen the period of burying work, and minimize downtime as a tourist spot.

As shown in FIG. 1, the pest detection and extermination system 100 of the present invention comprises a pest detection and extermination device 1000, a gateway 2000 and a center server 3000. FIG.

The pest detection and extermination device 1000 is used by being buried near buildings, houses, temples and shrines, and is used to detect and exterminate pests such as termites that live underground. The pest detection and extermination device 1000 is preferably buried in the ground with at least a portion, preferably only the zenith, visible from the outside. Preferably, at least one, and preferably more than one, pest detection and control device 1000 is used around the target building.

The pest detection and extermination device 1000 has a cylindrical shape and includes a bait chamber 1100, a power chamber 1200, a sensor chamber 1300, and a sensor substrate chamber 1400 inside. The feeding chamber 1100 occupies approximately half (a semicircular column of a cylinder, a semicylindrical shape), and is divided into an upper portion and a lower portion near the center in the height direction. The power room 1200 is located on the lower side in the height direction opposite to the food room 1100 , and the sensor room 1300 and the sensor base room 1400 are installed above the power room 1200 in the height direction. The sensor room 1300 is in contact with the bait room 1100 , and the sensor base room 1400 and antenna room 1500 are arranged so as not to contact the bait room 1100 . This is to completely eliminate the risk of insect pests entering the sensor base room 1400 and the antenna room 1500 .

The bait chamber 1100 is shaped like a fish cake by dividing a cylinder into semicircles, and is divided into two chambers, an upper bait chamber 1100A and a lower bait chamber 1100B. The upper bait chamber 1100 is designed to be 8.5 mm longer in the height direction than the lower bait chamber 1100 . The inside of the bait chamber 1100 is hollow, and is used to store a bait 1101 containing a chemical that inhibits molting of termites or the like and bait 1102 in the hollow portion. For the bait 1102, a bait material favored by the target insect pest is used. However, when targeting termites, which live in the soil and often damage buildings and the like, wood, roll paper, cardboard, and other paper materials are used. use. The bait 1101 and the bait 1102 are similar to the bait chamber 1100 and have a slightly smaller shape, and are shaped like a fish cake obtained by dividing a cylinder into semicircles.

The reason for installing two bait chambers 1100 is to accurately determine the degree of threat. When the number of baits is small, if a large number of pests rush in at once, they will be eaten up at once, and the total amount of pests cannot be determined in some cases. If there are two baits, it becomes easier to estimate the total amount of insect pests by visually checking the degree of decrease of the bait. Alternatively, part or all of the bait 1102 may be used to reduce the use of the expensive bait material 1101, and when the presence of pests is discovered, the bait 1102 may be replaced with the bait material 1101 to exterminate pests. be possible. Hereinafter, the term “bait” refers to both the bait material 1101 and the food 1102 .

The upper part of the upper food chamber 1100A is formed of a transparent monitoring glass 1104. As shown in FIG. The upper bait chamber 1100A is designed to be longer than the lower bait chamber 1100B, and the bait agent 1101 and the bait 1102 are stored and there is still room in the upper part. A styrofoam 1106 for visual recognition is inserted into this space. Pests, especially termites, cannot use styrofoam as bait, but because of its softness, they prefer to stick to styrofoam rather than bait, and it is said that styrofoam causes perforation damage. When termites invade the upper feeding chamber 1100A, they are guided to the styrofoam 1106 for visual recognition rather than to the bait, so that the activity status of the termites can be visually recognized through the transparent monitoring glass 1104.例文帳に追加

The bait chamber 1100 has an opening 1103 through which a sensing wire 1301 , which will be described later, can access the bait chamber 1100 . In the upper bait chamber 1100A, an upper opening 1103A is opened near the left end when viewed from the zenith direction, and in the lower bait chamber 1100B, conversely, a lower opening 1103B is opened near the right end when viewed from the zenith direction. . A sensing wire 1301 is installed in a sensor chamber 1300 to be described later and extends to the bait chamber 1100 via an opening 1103 . Sensing wire 1301 extending through upper opening 1103A contacts bait 1100 on the left side and urges bait 1100 to rotate clockwise. Sensing wire 1301 extending through lower opening 1103B contacts bait 1100 on the right side and urges bait 1100 to rotate counterclockwise.

A power source 1201 is installed in the power room 1200, and power from the power source is supplied to the sensor room and the sensor substrate room. As the power source 1201, a variety of batteries, such as a C battery, a D battery, a button battery, a thionyl chloride battery, and a rechargeable battery, can be used. A thionyl chloride battery, which is about the size of a AA battery, is most suitable for the power consumption of the device.

The sensing wire 1301 is installed in the sensor chamber 1300 , and part of it contacts the bait in the bait chamber 1100 through the opening 1308 and the sensing wire opening 1103 . Details of the sensing wire 1301 are shown in FIG. A recessed sensing wire fixing base 1305 is installed in the sensor chamber 1300, and a sensing wire tip connection terminal 1306 is provided at the tip, a sensing wire center connection terminal 1307 is provided at the center, and the other end is provided. there is

The sensing wire 1301 is composed of a conductive metal wire, has elasticity, and can be bent. The sensing wire tip portion 1302 is fixed by the sensing wire tip portion connection terminal 1306 in a state of being rotated around the center so as to draw a circle. It is connected to the central part connection 1307, and fixed by inserting the other end part 1303 of the sensing wire between the sensing wire fixing base and the other end of the wall 1309 that partitions the sensing wire.

By rotating the sensing wire 1301 once, a force is generated to restore the sensing wire 1301 to its original rod-like shape, and this force is used to generate the above-described urging force. Then, the density of the bait decreases as the bait is eaten by the pests. When the bait has a high density, it can resist the biasing force, but when the density becomes low and the bait becomes fragile, it can no longer resist the biasing force. As a result, the sensing wire 1301 gradually pushes into the bait chamber 1100 by its own restoring force and rotates the bait. When the sensing wire 1301 advances into the food chamber 1100 more than a certain amount, the connection between the sensing wire central portion 1304 and the sensing wire central portion connection terminal 1306 is cut off.

As a method for detecting this disconnection, the + pole of a power source 1201, which will be described later, is connected to the tip of the sensing wire, and the - pole of the power source 1202 is connected to the terminal for connecting the center of the sensing wire. Then, the presence or absence of contact between the sensing wire central portion 1304 and the sensing wire connection terminal 1306 can be easily determined based on the presence or absence of current. Many methods are known for determining the presence or absence of contact at the contact points, and other methods may be used to determine the presence or absence of contact between the sensing wire central portion 1304 and the sensing wire central portion connection terminal 1307. It is natural.

Conventional detection methods respond when the needle pierces the bait, but in many cases, they do not respond unless the pest eats the bait in close proximity to the bait. Although there were many cases where buildings were damaged, the method of the present invention can detect any part of the bait that has been eaten.

As a method for further facilitating detection, the bait was cut into a semicircular shape from a cylinder, but this may be further cut into a ginkgo-shaped column. Then, it is installed in the feed chamber 1100 so as to form a semicircular shape together with a styrofoam-made ginkgo-shaped column. Styrofoam originally has a low density and a weak force to resist the biasing of the sensing wire 1301 . Therefore, as soon as the pest eats the styrofoam, it can no longer resist the biasing of the sensing wire 1301 , the styrofoam portion is crushed, the bait rotates, and the sensing wire 1301 is drawn into the bait chamber 1100 . Pests, especially termites, which are the main pests, prefer to approach styrofoam more quickly than the bait 1102, which is useful. The bait may be of any other shape than the ginkgo biloba, and if at least part of the bait is made of polystyrene foam, the above effects can be obtained. The bait may be entirely replaced with polystyrene foam, but in that case, the biasing of the sensing wire 1301 must be adjusted so that it does not bite into the polystyrene foam without feeding damage.

A wireless device 1402 having a wireless function is installed in the sensor substrate chamber 1400, and its canopy is partitioned with transparent monitoring glass like the food chamber.

Wireless device 1402 includes transmitter 1402A, detector 1402B, timer 1402C, magnetic sensor 1402D, light emitting element 1402E, antenna 1402F, and thermometer 1402G. When the timer 1402C reaches a certain period of time, the detection unit 1402B determines whether or not the sensing wire center portion 1304 and the sensing wire center connection terminal 1307 are in contact with each other. , and transmitted to the outside through the antenna 1402F. At that time, the device ID set for each wireless device 1402 and the measurement count counted up by the timer 1402C for each cycle are also transmitted. If the numerical value of the thermometer 1402G indicates a preset abnormal value, that information is also transmitted. When the sensing wire central portion 1304 and the sensing wire central portion connection terminal 1307 are not in contact with each other, the second signal is generated by the transmitting portion 1402A and transmitted to the outside through the antenna 1402F. For example, if data is required once every 10 days, the fixed period may be less than half the period. One cycle is preferred. When another pest detection and extermination system 1000 of the present invention is communicating, transmission is not performed in order to prevent collision in wireless communication, and retransmission is performed after waiting for a while. At that time, the number of times transmission is refrained may be counted, and the counted number may be transmitted.

Although the pest detection and extermination device 1100 of the present invention is used by being buried in the ground, some vibration occurs at that time, and there is a possibility that a failure may occur. In addition, since it is expected to be buried for a long period of about five years, it is necessary to easily determine from the outside whether there is a failure due to aged deterioration. A magnetic force sensing device 1402E is used for this purpose, and senses the magnetic force by bringing a magnet or the like close to it from the outside, and the light emitting element 1402E emits light for a short period of time. It can be confirmed that the wireless device 1402 is operating by visually recognizing it through the monitoring glass of the canopy. Although the antenna 1402F needs to be installed near the surface of the ground, the temperature changes more rapidly than underground, and the possibility of dew condensation increases. Especially when dew condensation occurs, there is a risk that the wireless device may malfunction, so an antenna room is separately provided near the ground surface, only the antenna 1402F and the light emitting element 1402E are installed in the antenna room, and the remaining wireless device 1402 is installed in the sensor board room 1400. You can do it.

The first and second signals transmitted from the antenna 1402F are extremely weak due to power supply problems, and cannot be expected to reach the center server 3000 directly. Therefore, the gateway 2000 is installed near or inside the target building. If the target is a very wide range and it cannot be expected that the first signal and the second signal are reliably delivered to gateway 2000 , signal relay device 2300 may be used to relay them to gateway 2000 . The signal relay device 2300 may be appropriately installed in a place where the signal can be relayed according to the range of the pest detection and extermination device 1100 of the present invention embedded in the range. The gateway 2000 comprises a receiving device 2100 that receives the first and second signals transmitted from the antenna 1402F, and a transmitting device 2200 that transmits the first and second signals to the center server 3000 in the distance.

When the first signal is received, it means that the bait has not been eaten by pests, and that fact is transmitted to center server 3000 together with the device ID using transmission device 2200 . Since this is a normal state, the information is stored in the gateway 2000 instead of being transmitted immediately when the first signal is received, and another pest is detected at a timing such as once every 10 days or once a month. Together with the information about the first signal from the extermination device 1000, it is transmitted to the center server 3000 all at once. If gateway 2000 is expected to have abundant power, it may be configured to transmit to center server 3000 each time it receives the first signal. If the second signal is received, it means that the food is being eaten by pests, which is an emergency. Therefore, the information about the second signal and the device ID are immediately transmitted to the center server 3000 even if the transmission timing does not come. Although the transmitting device 2200 has a function capable of transmitting information using the Internet, other communication means may be used.

The center server 3000 comprises a receiving device 3100 capable of receiving information transmitted by the gateway 2000, a display device 3200 capable of displaying various information, and a notification device 3300 capable of transmitting information to the outside. When the information about the first signal is provided, the center server 3000 can record that fact and display the contents on the display device 3200 as necessary. When the information about the second signal is provided, the equipment such as a preset e-mail address, mobile phone, etc. is notified that the emergency itself has occurred. By the operation, the display device 3200 displays the name and address of the building in which the pest detection and extermination device 1000 that has issued the second signal is embedded, and a simple map showing the location where the pest detection and extermination device is embedded. It can be printed using a printing device.

Next, the installation method of the pest detection and extermination system 100, the pest detection method, and the pest extermination method will be described.

First, the presence or absence of pests is detected, and the pest detection and extermination device 1000 is buried in the soil of a location to be exterminated. Instead of the bait material 1101, an inexpensive bait 1102 is set as the bait. It is most preferable to completely bury the pest detection and extermination device 1000 so that only the monitoring glass, which is the canopy of the pest detection and extermination device 1000, can be seen from the ground. As another method, a net-like or prison-like outer shell may be buried in the ground and installed inside the outer shell. In the market, various pest control burial devices are commercially available, and they are particularly effective when they are already installed.

Once embedded, the magnet is brought close to the monitoring glass to confirm that the magnetic force sensing device 1402D functions and the light emitting element 1402E emits light. If the luminous element 1402E does not emit light, some problem has occurred, so the pest detection and extermination device 1000 is replaced. Wireless device 1402 is initially in a sleep state to reduce battery consumption. When the magnetic force sensing device 1402D senses a magnetic force, the wireless device 1402 is activated, communicates with a setting device (not shown), receives various setting information such as a communication cycle, and starts operation based on the setting information. By repeating this work, the pest detection and extermination device 1000 is buried around the target building according to its importance.

As long as the bait chamber 1100 is not infested with pests, the bait 1102 is sufficiently dense. The bait 1102 contacts while being urged by the sensing wire 1301, but the bait 1102 resists this urging and does not rotate. If this state continues, the first signal is transmitted through the antenna 1402F at a preset cycle, such as once every 10 days or once a month.

When pests invade the bait chamber 1100 and eat the bait 1102, the bait 1102 decreases in density and changes to a hollow state. Then, it becomes impossible to resist the sensing wire 1301 that is biased near the end of the bait material. When the area in contact with the sensing wire 1301 is eaten by pests, the sensing wire 1301 digs into the eaten area. Even if an area distant from the area in contact with the sensing wire 1301 is eaten, the area is crushed by the force of the sensing wire 1301, and the entire bait 1102 fills the crushed area. It acts to create a "rotational" motion and pull the sensing wire 1301 into the back of the bait chamber 1100.

As the sensing wire 1301 is pulled deeper into the bait chamber 1100, the connection between the sensing wire central portion 1304 and the sensing wire central portion connection terminal 1307 is cut off at a certain point. When the above period arrives in this state, the second signal is transmitted through the antenna 1402F. Note that the second signal may be transmitted to the outside at the moment when the sensing wire central portion 1304 and the sensing wire central portion connection terminal 1307 are disconnected. The latter configuration is useful in highly critical buildings.

Upon receiving the first signal, gateway 2000 stores it in an internal storage area together with the device ID, and transmits it to center server 3000 at regular intervals. When the second signal is received, it immediately transmits to the center server 3000 that the second signal has been received together with the device ID.

Upon receiving the first signal, center server 3000 can store the information in an internal storage area, and display the information on display device 3200 as necessary. When the center server 3000 receives the second signal, it can cause the display means 3200 to display to that effect, and can contact pre-registered devices through the notification device 3300, so that a large number of pest detection and extermination devices 1000 can be installed at multiple locations. is buried for a long period of time, when a pest is detected, it is immediately possible to know where the pest detection and extermination device 1000 in which the pest has invaded. The device ID of the pest detection and extermination device 1000 embedded and the location where the device ID is embedded may be managed in advance and displayed on a map. In this case, since the location where the pest is detected can be easily known, the initial action can be hastened.

If the pest detection and extermination device 1000 is buried for a long period of time, dust may accumulate on its surface and the position may not be immediately specified. can be identified. When viewing the pest detection and extermination device 1000 through the monitoring glass 1104, at least some of the pests that have eaten the bait 1102 also eat the Styrofoam 1105 for visual recognition, so that the situation can be observed.

When the insect pest is confirmed, the bait 1102 is replaced with the bait material 1101 and buried again. By the effect of the bait material 1101, insect pests are inhibited from moulting, and many of them can be killed in the medium term. It is more preferable to replace the bait material 1101 with the bait material 1101 not only for the pest detection and extermination device 1000 in which pests have been confirmed, but also for other pest detection and extermination devices 1000 buried around it.

Although the pest detection and control system 100 of the present invention has been described, it is not necessarily bound by this specification and can be applied in various modifications.

Although the embodiments of the present invention have been described above, part or all of the embodiments of the present invention are described as the following additional remarks.
