Abstract
Description
Technical Field
[0001] This application relates to the technical field of water conservancy projects, and particularly to a termite sound excitation acquisition device and a method for detecting termite nests in dams. Background Art
[0002] Termites are an important factor affecting the safety of earth-rock dams. Termites building nests on dams will form channels, damaging the compactness and overall structure of the dams. These nest channels can become leakage channels, and in severe cases, they will endanger the safety of the dams and cause the dams to collapse. The prevention and control of termites in earth-rock dams is crucial for ensuring the safety and normal operation of the dams. The primary problem faced is to effectively detect the location of termite nests. Since the termite nests are hidden and there is no obvious definite rule between the surface indicators of the nests and the nests, finding the nests usually relies on large-scale manual excavation, which severely damages the dam body. Therefore, there is an urgent need for a method to quickly and accurately find termite nests.
[0003] After being threatened, termites will tap their heads to emit drumming sounds to warn other termites of danger, and this sound usually spreads throughout the nest. Existing research has proven that by collecting this sound with multiple sensors and using a certain algorithm, the coordinates of the termite nest can be accurately located. However, the termites in the dam are isolated from the outside world and are not so easily threatened to emit warning sounds. To locate the termite nest through the warning sounds of termites, a device and method are needed to actively stimulate the termites in the nest to emit such sounds. Currently, such a device and method have not appeared in relevant literature and reports. Summary of the Invention

[0028] In view of the problem that the existing devices and methods for locating termite nests in dams by sound cannot actively stimulate termites in the nests to emit warning sounds, this application provides a termite sound excitation and collection device and a method for detecting termite nests in dams, which can actively stimulate termites to make sounds, shorten the waiting time required for detecting termite nests by termite sounds, and improve the efficiency of detecting termite nests in dams.
[0029] The following will further describe in detail the specific implementation manners of this application in conjunction with the drawings and embodiments. The following embodiments are used to illustrate this application, but are not used to limit the scope of this application.
[0030] An embodiment of this application provides a termite sound excitation and collection device, as Figure 1 shown, including a vibration excitation device and a collection device; the vibration excitation device is used to continuously emit multiple segments of special sound waves into the soil mass inside the dam, and the special sound waves include an excitation segment and a silent segment in chronological order; the excitation segment is an excitation signal for stimulating termites to make sounds, and the silent segment is silent; the collection device is used to collect the feedback signal of the soil mass inside the dam.
[0031] In some embodiments, the vibration excitation device and the collection device are integrated on a probe rod.
[0032] In some embodiments, the excitation signal includes various sound signals of termites, termite natural enemies, and other stimuli that can stimulate termites to make sounds.
[0033] In some embodiments, the working times of the vibration excitation device and the collection device are synchronized.
[0034] In some embodiments, the chronological feature of the special sound wave is that the excitation segment includes 0s to 10s, and the silent segment includes 11s to 26s.
[0035] In some embodiments, the burial depths of both the vibration excitation device and the collection device are at a certain position below the soil layer.
[0036] In some embodiments, the feedback signal includes the sound signal emitted by the excitation device, various environmental sound signals inside the dam, and the sound signal emitted by termites after being excited.
[0037] As Figure 1 shown, the termite sound excitation acquisition device consists of an excitation device and an acquisition device assembled on a probe rod. First, the termite sound excitation acquisition device is buried in any area to be detected on the dam, and then a special sound signal is emitted into the soil inside the dam through the excitation device of the termite excitation acquisition device. This sound signal consists of an excitation segment and a silent segment signal in sequence; the sound in the excitation segment contains various sound signals of termites, termite natural enemies, and other sounds that can stimulate termites to make sounds; the silent segment silences all the emitted sounds, and the sound feedback from the termites in the nest during the silent segment is collected by the acquisition device to determine whether there is a termite nest in the detection area.
[0038] The excitation device and the acquisition device on the probe rod are time-synchronized and work simultaneously. The burial depths of both the excitation device and the acquisition device are at a certain position below the soil layer. The function of the excitation segment is to stimulate termites inside the dam to make sounds, and the function of the silent segment is to avoid misjudgment caused by the interference of the sound collected from termites by the excitation segment. The sound in the excitation segment contains various sound signals of termites, termite natural enemies, and other sounds that can stimulate termites to make sounds. These sound signals that can stimulate termites to make sounds can be emitted simultaneously or staggeredly. The sound signal collected by the acquisition device includes the sound signal emitted by the exciter, various environmental sound signals inside the dam, and the sound signal emitted by termites after being excited. Only when the sound of termites is collected during the silent segment is it determined that the termites in the nest emit a response sound, and there is a termite nest in the detection area.
[0039] The embodiment of the present application also provides a method for detecting termite nests in a dam, which is implemented by using the above-mentioned termite sound excitation acquisition device; the method for detecting termite nests in a dam includes: inserting a plurality of termite sound excitation acquisition devices at multiple corner points of the area to be detected in the dam, so that both the excitation device and the acquisition device are at a certain depth below the soil layer; turning on the excitation device and the acquisition device, and enabling the excitation device to continuously emit multiple segments of special sound waves into the dam soil, and the acquisition device collects the feedback signal of the dam soil; only when the acquisition device collects the sound signal of termites during the silent segment, it is determined that the termites in the nest emit a response signal, and there is a termite nest in the area to be detected.
[0040] In some embodiments, the method for detecting termite nests in a dam further includes: based on the termite sound signals collected by a plurality of termite sound excitation acquisition devices, combining a positioning algorithm to locate the position of the termite nest in the area to be detected.
[0041] In some embodiments, the method for detecting termite nests in dikes further includes: if no termite sound signal is collected by each termite sound excitation and collection device during the silent period, it is determined that there is no termite nest in the area to be detected.
[0042] The method for detecting termite nests in dikes provided by the present application will be described below through specific embodiments.
[0043] Embodiment
[0044] Step 1: As Figure 1 , indicators of the presence of termites such as mud covers, mud lines, and swarming holes are found in an area on the dike. Four termite sound excitation and collection devices proposed in the present application are inserted at the square corners with a side length of Nm near this area, ensuring that both the excitation device and the collection device are 5 cm below the soil layer to avoid interference from external environmental noise.
[0045] Step 2: Turn on the excitation device and the collection device, and let the excitation device and the collection device on the probe rod work simultaneously. The excitation device emits a pre-set special sound wave, and the collection device simultaneously collects sound signals. The time-domain characteristics of the special sound wave are as Figure 1 shown, consisting of an excitation section and a silent section arranged alternately. The duration of the excitation section is 0 s to 10 s, including sound wave signals that can stimulate termites to emit response sounds; the period from 10 s to 11 s is a gap between the excitation section and the silent section, during which the excitation device does not emit any sound at all. The termite sound signal collected by the collection device may be a signal reflected by the stimulation signal emitted by the exciter during the excitation section, so it is not determined as a response signal after the termites are stimulated; the duration of the silent section is 11 s to 26 s, during which the excitation device does not emit any sound at all, and the termite sound signal collected by the collection device during the silent section is determined as a response sound signal after the termites are stimulated.
[0046] Step 3: According to the statistical data in the laboratory and on-site, different types of termites will surely emit response sounds after the excitation device emits a special sound signal Ts. Set the excitation device and the collection device to stop working after running for 1.5Ts to complete this collection. When the program algorithm detects termite sounds during the silent period, it indicates that the excitation and collection of termite sounds are successful, and there are termites in this area; based on the sound information collected by multiple termite sound excitation and collection devices located at different positions, combined with the positioning algorithm, the position of the termite nest in this area is located. If no termite sound is detected by each termite sound excitation and collection device during the silent period, it is determined that there are no termites in this area.
[0047] Step 4: Change the position of the detection square area and re-execute Step 1 to Step 3 until the entire area to be detected is traversed by the square area.
[0048] The termite sound excitation and acquisition device and the levee termite nest detection method provided by the embodiments of the present application insert a plurality of termite sound excitation and acquisition devices at multiple corner points of the area to be detected in the levee, so that both the vibration excitation device and the acquisition device are at a certain depth below the soil layer. The vibration excitation device and the acquisition device are turned on, and the vibration excitation device continuously emits multiple segments of special sound waves to the levee soil mass. The acquisition device acquires the feedback signal of the soil mass inside the levee. When and only when the acquisition device acquires the termite sound signal during the silent period, it is determined that the termites in the nest emit a response signal, and there is a termite nest in the area to be detected. The vibration excitation device can actively stimulate the termites to make sounds, which can shorten the waiting time required for detecting termite nests through termite sounds and improve the efficiency of levee termite nest detection; integrating the device for stimulating termites to make sounds and the device for acquiring termite sounds makes the technology for locating the position of levee termite nests through termite sounds easier to operate.
