[0028] Termites build nests, build roads, and reproduce on dams, which will bring major risks to the safe operation of reservoir dams, dikes and other projects. Termite nest detection is a key link in the prevention and control of dam termite damage. Existing physical detection methods such as ground penetrating radar method, high-density resistivity method and other electrical equipment and instruments are complex to deploy, and detection has high requirements for site flatness and measurement point density. In addition, the structure and materials of the nest itself are complex, and the difference between the geophysical parameters and the surrounding soil is unclear, so the final measurement accuracy is often not high.

[0029] There are examples showing that sound sensors can detect low-frequency sound pulse signals emitted by termites. The frequency of sound pulse signals emitted by termites is between 1Hz and 5000Hz. However, existing general sound detection equipment has a wide detection frequency range (20Hz to 20000Hz), poor passive noise reduction capabilities, and low accuracy in the 1Hz to 5000Hz range. High-performance sound detection equipment is expensive. At present, there is a lack of sensor probes and intelligent detection equipment with good applicability, low price, and easy promotion that can be used efficiently and accurately for the detection and positioning of termite nests on dams.

[0030] In response to the above problems, an embodiment of the present application provides an intelligent detection and positioning device for termite nests on dams, which can efficiently and accurately detect and locate termite nests on dams.

[0031] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but are not intended to limit the scope of the present application.

[0032] The intelligent detection and positioning device for termite nests on dams provided in this embodiment includes an intelligent sensor, an intelligent positioning device and a terminal; the intelligent sensor is communicatively connected to the terminal, and is used to receive a sound wave pulse signal emitted from the dam termite nest, and send the sound wave pulse signal to the terminal; the terminal is communicatively connected to the intelligent positioning device, and is used to send instructions to the intelligent positioning device according to the sound wave pulse signal; the intelligent positioning device is used to carry the intelligent sensor, and control the movement of the intelligent sensor according to the instruction, so that the intelligent sensor is close to the termite nest.

[0033] In one embodiment, Figure 1 As shown, the smart sensor 1 includes a probe 101, a wireless transmission module 102, a waterproof shell 103, and an air conduction medium 104, a sensor group 105 and a sensor fixing device 106 arranged in the waterproof shell 103; wherein the probe 101 and the wireless transmission module 102 are respectively arranged at two ends of the waterproof shell 103.

[0034] In one embodiment, the probe comprises a sound conducting membrane made of a metallic material.

[0035] In one embodiment, Figure 1 As shown, the sensor group 105 includes an acceleration sensor 1051, a pressure sensor 1052 and a velocity sensor 1053; one end of the acceleration sensor 1051 is connected to the sensor fixture 106, and the other end is connected to the probe 101; one end of the pressure sensor 1052 is connected to the sensor fixture 106, and the other end is located in the air conduction medium 104; one end of the velocity sensor 1053 is connected to the sensor fixture 106, and the other end is connected to the probe 101.

[0036] In one embodiment, the acceleration sensor 1051, the pressure sensor 1052 and the speed sensor 1053 respectively receive the sound wave pulse signal emitted from the dam termite nest, and send the sound wave pulse signal to the terminal.

[0037] In one embodiment, Figure 1 As shown, the smart sensor 1 also includes a sound insulation and shockproof ring 107 and a sound insulation and filling material 108; the sound insulation and shockproof ring 107 is used to block the vibration noise on both sides of the sensor, and the sound insulation and filling material 108 is used to block the vibration noise between the detection components.

[0038] In application, the smart sensor has the ability of passive noise reduction. The output pressure (1Hz ~ 500Hz frequency band), speed (500Hz ~ 2000Hz frequency band), acceleration (2000Hz ~ 5000Hz frequency band) three groups of signals can envelope the frequency range of low-frequency sound pulses in termite nests (1Hz ~ 5000Hz), improve the detection accuracy of each frequency band, and the received signal can be transmitted back to the terminal for analysis through the wireless transmission module. The smart positioning device is used to carry and move smart sensors. Combined with the signal detected and transmitted by the smart sensor, the terminal calculates and sends instructions to the smart positioning device, so that it automatically adjusts the position of the smart sensor on the track, so that it keeps approaching the termite nest, and achieves the purpose of quickly locating the termite nest.

[0039] In the application, the velocity sensor and the accelerometer are connected to the sound conduction membrane, and receive low-frequency sound pulse signals by metal vibration. The pressure sensor is not connected to the sound conduction membrane, but is located in a closed air conduction medium, and receives low-frequency sound pulse signals by air vibration. The intelligent sensor receives three groups of sound wave pulse signals detected by the accelerometer, pressure sensor, and velocity sensor, respectively (M0, M1, ...M n ), (N0, N1, ... N n ), (L0, L1, ... L n ), 0~n is the time sequence of the pulse signal, which is sent to the terminal through the wireless transmission module. The terminal receives three groups of sound wave pulse signals (M0, M1, ...M n ), (N0, N1, ... N n ), (L0, L1, ... L n ) and then the minimum termite sound intensity D determined by indoor test min As the threshold, the three groups of sound wave pulse signals (M0, M1, ...M n ), (N0, N1, ... N n ), (L0, L1, ... L n ), if there is a group of sound wave pulse signal strength greater than D min , which means that the intelligent sensor detects the low-frequency sound pulse signal emitted by termites. Otherwise, it means that the low-frequency sound pulse signal emitted by termites is not detected, and the conclusion is given that no termite nest is found.

[0040] In one embodiment, Figure 2 As shown, the intelligent positioning device 2 includes a horizontal moving track 201, a vertical moving track 202, a track fixing frame 203, an anchoring pile 204, a horizontal linear track slider 205, a vertical linear track slider 206 and an indicating slider 207; wherein, as Figure 3 As shown, the indicating slider 207 is connected to the smart sensor via a retractable connecting device 208 .

[0041] In one embodiment, the intelligent positioning device controls the movement of the horizontal linear rail slider 201 and the vertical linear rail slider 202 to achieve the movement of the indicating slider 207 , thereby controlling the movement of the intelligent sensor.

[0042] In application, the intelligent positioning device can realize the movement of the indicating slider and the intelligent sensor carried by it by moving the horizontal linear rail slider and the vertical linear rail slider. The position and movement distance of the linear rail slider can be controlled by the terminal. The intelligent sensor can be assembled with the indicating slider through a specific retractable connection device, which can be disassembled and separated. The terminal can control the retractable connection device on the indicating slider to make the front end of the intelligent sensor probe close to the point to be tested. After the terminal receives and analyzes the signal, if a termite nest is found, it can determine the approximate location of the termite nest based on the signal characteristics, and then send instructions to the intelligent positioning device to make the indicating slider and the intelligent sensor it carries move closer to the termite nest. After multiple detections and movements, the nest position is finally determined within a limited range.

[0043] In actual application, the intelligent detection and positioning device for termite nests on dams provided by the embodiment of the present application can first determine the dam area to be detected, fix the anchor piles of the intelligent positioning device at the four corners of the detection area, assemble the track fixing frame, horizontal moving track, vertical moving track, horizontal and vertical linear rail sliders, and indicator slider. The intelligent sensor can be placed close to the surface of the dam soil, or it can be placed as shown in the figure. Figure 4 As shown, the smart sensor is buried in a shallow hole to achieve a more stable detection effect. The specific situation depends on the flatness of the dam surface and whether there is grass or other conditions that affect the detection. If the dam surface is flat and there is no vegetation, the smart sensor can be fixed on the indicator slider, and the smart positioning device can automatically stick to the dam test point or leave the dam test point. If the dam surface is uneven or there is vegetation, the front-end probe of the smart sensor cannot stick to the dam test surface, then the smart sensor can be separated from the indicator slider on the smart positioning device, and the indicator slider is initially still directly above each smart sensor. Dig a 10cm deep cylindrical hole on the dam surface below the indicator slider, compact the bottom of the hole, and bury the smart sensor.

[0044] After the intelligent sensor detection is turned on and the signal is collected for 1 minute, the intelligent sensor obtains three sets of analog signals (M0, M1, ... M1) from the acceleration sensor, pressure sensor, and velocity sensor respectively. n ), (N0, N1, ... N n ), (L0, L1, ... L n ), which is sent to the terminal through the wireless transmission module on the intelligent sensor. The terminal uses the minimum termite sound intensity D determined by the experiment. min As the threshold, the three groups of detection signals (M0, M1, ...M n), (N0, N1, ... N n ), (L0, L1, ... L n ), if there is a group of detection signal strength greater than D min , indicating that the smart sensor detects the low-frequency sound pulse signal emitted by termites, otherwise it indicates that the smart sensor does not detect the low-frequency sound pulse signal emitted by termites. If at least one smart sensor detects the low-frequency sound pulse signal emitted by termites, the relative position of the termite nest and the smart sensor can be roughly determined. At the same time, the terminal can issue an instruction to move the indicating slider to a position closer to the termite nest. If the smart sensor and the indicating slider are in an unseparated state at this time, and the detection method is adopted to close the surface of the dam, the detection and positioning device automatically separates the front end of the smart sensor from the surface to be measured of the dam, and moves the indicating slider and the smart sensor to a new position closer to the termite nest according to the terminal instruction for re-measurement; if the smart sensor and the indicating slider are in a separated state, the indicating slider first moves to a new position closer to the termite nest according to the terminal instruction, and then the smart sensor is manually excavated, and the smart sensor is re-buried according to the new position of the corresponding indicating slider, and re-measured. Finally, by moving the indicating slider and the smart sensor carried by it a limited number of times, the nest position is determined within a limited range.

[0045] The intelligent detection and positioning device for termite nests on dams provided in the embodiment of the present application outputs high-precision analog signals of termite sound pulses in different frequency bands by taking advantage of the measurement accuracy of a group of sensors in each frequency band. The intelligent sensor is mounted on a movable track frame controlled by a terminal, and can automatically adjust the position of the sensor to keep approaching the termite nest, thereby realizing intelligent automatic positioning of detection and improving positioning efficiency and accuracy.
