Technical Field

[0001] This application relates to the field of testing and evaluation, and in particular to a method, apparatus, equipment and medium for testing and evaluating the sound insulation performance of buildings. Background Technology

[0002] With economic and urban development, population density is constantly increasing, and environmental noise is having an increasingly serious impact on human life. At present, environmental noise has become one of the biggest public hazards to human living environment. Therefore, the sound insulation performance of buildings directly affects people's living experience.

[0003] In civil buildings, standardized acceptance testing is essential to ensure consistent quality across all construction projects, which is crucial for public safety. Currently, many technologies involve a person manually emitting sound using a handheld device while another person records the sound using a separate handheld receiver. The building's sound insulation performance is assessed by measuring the decibel levels of the audio signals. However, manually evaluating the sound insulation of an entire building is inefficient and increases the workload for the personnel involved. Summary of the Invention

[0004] In order to improve the efficiency of evaluating the sound insulation performance of buildings and reduce the workload of relevant personnel when testing the sound insulation performance of buildings, this application provides, in particular, a method, apparatus, equipment and medium for testing and evaluating the sound insulation performance of buildings.

[0005] Firstly, this application provides a method for testing the sound insulation performance of a building, employing the following technical solution:

[0006] A method for testing the sound insulation performance of buildings, including

[0007] Control the sound-emitting devices in the current evaluation area to emit sound according to preset rules, including preset path, sound emission duration and sound emission decibel value;

[0008] Receive live audio transmitted by a recording device, wherein the live audio is collected by the recording device after the sound-emitting device emits sound;

[0009] Based on the on-site audio, determine the on-site decibel value of the on-site audio;

[0010] When the on-site decibel value exceeds the preset standard sound insulation decibel value, it is determined that the sound insulation performance of the area to be evaluated is abnormal and abnormal information is generated. The abnormal information includes at least the location of the area to be evaluated and the abnormal inducing factors.

[0011] By adopting the above technical solution, the sound source devices in the area to be evaluated are controlled to emit sound at a preset frequency along a pre-set moving route and at a preset decibel value, so that the sound receiving device can collect audio and transmit the collected on-site audio to the electronic device. After receiving the on-site audio sent by the sound receiving device, the electronic device determines the on-site decibel value corresponding to the on-site audio. When the on-site decibel value is higher than the preset standard sound insulation decibel value, it is determined that the sound insulation performance of the area to be evaluated is abnormal, and abnormal information is generated. By controlling the sound generating and sound receiving devices to evaluate the building sound insulation performance of the area to be evaluated, the work efficiency is improved and the workload of relevant personnel is reduced.

[0012] In one possible implementation, before determining the on-site decibel value of the on-site audio based on the on-site audio, the method further includes:

[0013] The on-site audio is subjected to noise reduction processing.

[0014] By adopting the above technical solution and performing background noise reduction on the on-site audio, the interference of other factors on the on-site audio is reduced, thereby improving the accuracy of building sound insulation testing and evaluation.

[0015] In one possible implementation, determining the on-site decibel value of the on-site audio based on the on-site audio includes:

[0016] An audio waveform diagram is generated based on the on-site audio.

[0017] Based on the audio waveform, determine the average decibel value within the preset time period;

[0018] The average decibel value is determined as the on-site decibel value.

[0019] By adopting the above technical solution, an audio waveform diagram corresponding to the on-site audio is generated from the on-site audio. The audio waveform diagram can more intuitively display the decibel value generated by the on-site audio. Based on different decibel values, the average decibel value within a preset time period is determined, and the average decibel value is determined as the on-site decibel value. By using the average decibel value to determine the on-site decibel value, the accuracy of the detection results is improved.

[0020] In one possible implementation, when the on-site decibel value exceeds a preset standard sound insulation decibel value, it is determined that the sound insulation performance of the area to be evaluated is abnormal and abnormal information is generated, including:

[0021] When the on-site decibel value exceeds the preset standard sound insulation decibel value, the thickness of the wall in the area to be evaluated is detected to obtain the wall thickness value;

[0022] Based on the wall thickness value, determine whether the wall in the area to be evaluated meets the building standards. If the wall thickness does not meet the building standards, then determine that the inducing factor in the abnormal information is abnormal wall thickness.

[0023] If the wall thickness meets the building standards, then the wall building material in the area to be evaluated is determined to meet the building standards. If the wall building material does not meet the building standards, then the inducing factor in the abnormal information is determined to be abnormal wall building material.

[0024] By adopting the above technical solution, when the on-site decibel value exceeds the preset standard sound insulation decibel value, the wall thickness and wall material in the area to be evaluated are detected to generate abnormal information, which makes it easier to intuitively show the abnormal situation in the area to be evaluated.

[0025] In one possible implementation, after the detection and evaluation of the current region to be evaluated is completed, the following steps are also included:

[0026] Acquire the first position of the sound-emitting device, the first position of the sound-receiving device, and acquire panoramic images of the current area to be evaluated and the next area to be evaluated.

[0027] The moving image is determined based on the panoramic image of the current area to be evaluated and the panoramic image of the next area to be evaluated.

[0028] A first path is obtained based on the first position of the moving image, the first position of the sound-emitting device, and the moving image;

[0029] The first path is sent to the sound-emitting device and the sound-receiving device so that the sound-emitting device and the sound-receiving device can move along the first path.

[0030] By adopting the above technical solution, a moving image is determined by acquiring panoramic images of the current area to be evaluated and the next area to be evaluated, and a first path is determined based on the first position of the sound-emitting device, the first position of the sound-receiving device, and the moving image, so that the sound-emitting device and the sound-receiving device move along the first path, thereby reducing the workload of relevant personnel in the process of testing and evaluating the sound insulation performance of buildings.

[0031] In one possible implementation, sending the first path to the sound-emitting device and the sound-receiving device to enable the sound-emitting device and the sound-receiving device to move along the first path includes:

[0032] During the movement of the sound-emitting device and the sound-receiving device, the second position, movement speed, and curvature information of the sound-emitting device and the sound-receiving device are acquired in real time to determine the movement direction of the sound-emitting device and the sound-receiving device and generate a turning command;

[0033] The turning command is sent to the sound-generating device and the sound-receiving device to control the sound-generating device and the sound-receiving device to move along the first path.

[0034] By adopting the above technical solution, the positions of the sound-emitting device and the sound-receiving device during movement are acquired in real time, and their movement speed and curvature information are determined. Based on the movement speed and curvature information, the movement direction of the sound-emitting device and the sound-receiving device is determined, and finally a turning command is generated. After the electronic device sends the generated turning command to the sound-emitting device and the sound-receiving device, it can control the sound-emitting device and the sound-receiving device to move along the first path. By controlling the movement of the sound-emitting device and the sound-receiving device through the turning command, the probability of collision between the sound-emitting device and the sound-receiving device during movement is reduced.

[0035] In one possible implementation, when the recording device reaches a set range of the target location, positioning information is acquired, which is emitted by the recording device after it has reached the set range;

[0036] Based on the positioning information, a start command is generated and sent to the sound-generating device and the sound-receiving device, so that the sound-generating device and the sound-receiving device can start working after receiving the start command.

[0037] By adopting the above technical solution, after receiving the positioning information sent by the sound-generating device and the sound-receiving device, a start command is generated to control the sound-generating device and the sound-receiving device to start working, which reduces the workload of relevant personnel in the testing and evaluation process, thereby alleviating the workload of relevant personnel.

[0038] Secondly, this application provides a device for testing and evaluating the sound insulation performance of buildings, which adopts the following technical solution:

[0039] A device for testing and evaluating the sound insulation performance of buildings, comprising:

[0040] The sound control module is used to control the sound-emitting devices in the current evaluation area to emit sound according to preset rules, which include preset path, sound duration and sound decibel value;

[0041] An audio receiving module is used to receive live audio transmitted by a recording device, wherein the live audio is the live audio collected after the sound-emitting device emits sound;

[0042] The decibel value determination module is used to determine the on-site decibel value of the on-site audio based on the on-site audio.

[0043] The anomaly detection module is used to determine that the sound insulation performance of the area to be evaluated is abnormal and generate anomaly information when the on-site decibel value exceeds the preset standard sound insulation decibel value. The anomaly information includes at least the location of the area to be evaluated and the factors that induce the anomaly.

[0044] By adopting the above technical solution, the sound source devices in the area to be evaluated are controlled to emit sound at a preset frequency along a pre-set moving route and at a preset decibel value, so that the sound receiving device can collect audio and transmit the collected on-site audio to the electronic device. After receiving the on-site audio sent by the sound receiving device, the electronic device determines the on-site decibel value corresponding to the on-site audio. When the on-site decibel value is higher than the preset standard sound insulation decibel value, it is determined that the sound insulation performance of the area to be evaluated is abnormal, and abnormal information is generated. By controlling the sound generating and sound receiving devices to evaluate the building sound insulation performance of the area to be evaluated, the work efficiency is improved and the workload of relevant personnel is reduced.

[0045] Thirdly, this application provides an electronic device that adopts the following technical solution:

[0052] In summary, this application includes at least one of the following beneficial technical effects:

[0053] 1. By controlling the sound source devices in the area to be evaluated to emit sound at a preset frequency along a pre-set movement route and at a preset decibel value, the sound receiving device can collect audio and transmit the collected on-site audio to the electronic device. After receiving the on-site audio sent by the sound receiving device, the electronic device determines the on-site decibel value corresponding to the on-site audio. When the on-site decibel value is higher than the preset standard sound insulation decibel value, it is determined that the sound insulation performance of the area to be evaluated is abnormal, and abnormal information is generated. By controlling the sound generating and sound receiving devices to evaluate the sound insulation performance of the area to be evaluated, the work efficiency is improved and the workload of relevant personnel is reduced.

[0057] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0058] After reading this specification, those skilled in the art may make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0060] To meet people's living requirements, newly built buildings are getting taller and taller. However, as buildings become taller, measures must be taken to reduce their weight for safety. This leads to the development of lightweight partition wall materials. These materials are very light and also have fireproof and soundproof properties. However, they are relatively expensive. Some developers may use inferior materials instead of lightweight partition wall materials to reduce construction costs, resulting in new buildings that do not meet building standards for sound insulation.

[0061] In related technologies, the sound insulation performance of newly built buildings is mostly assessed by manual handheld measuring instruments. However, since newly built buildings are often tall and have a large number of rooms, assessing the sound insulation performance of the entire building increases the workload of the staff.

[0062] In view of the above-mentioned technical problems, this application provides a method for testing and evaluating the sound insulation performance of buildings, which can improve the efficiency of evaluating the sound insulation performance of buildings and reduce the workload of relevant personnel when testing the sound insulation performance of buildings. By controlling the sound source device in the area to be evaluated to emit sound at a preset frequency under a preset movement route and sound emission decibel value, the sound receiving device can collect audio and transmit the collected on-site audio to the electronic device. After receiving the on-site audio sent by the sound receiving device, the electronic device determines the on-site decibel value corresponding to the on-site audio. When the on-site decibel value is higher than the preset standard sound insulation decibel value, it is determined that the sound insulation performance of the area to be evaluated is abnormal and an abnormality information is generated. By controlling the sound emitting device and the sound receiving device to evaluate the sound insulation performance of the area to be evaluated, the work efficiency is improved and the workload of relevant personnel is reduced.

[0063] For ease of understanding, the system architecture to which the technical solution of this application applies is described below, including:

[0064] At least one sound-generating device, at least one sound-receiving device, and electronic equipment.

[0065] The audio emitted by the sound-generating device can be collected by a recording device. The recording device converts the collected ambient audio into an audio signal and sends it to an electronic device. After receiving the audio signal from the recording device, the electronic device can convert the audio signal back into ambient audio and perform sound insulation performance testing and evaluation. The electronic device can communicate with the sound-generating device and control the sound-generating device to emit sound and move.

[0066] Specifically, this application provides a method for testing and evaluating the sound insulation performance of a building, executed by an electronic device. This electronic device can be a server or a terminal device. The server can be a standalone physical server, a server cluster or distributed system composed of multiple servers, or a cloud server providing cloud computing services. The terminal device can be a smartphone, tablet, laptop, desktop computer, etc., but is not limited to these. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, and this application does not impose any limitations on this.

[0067] refer to Figure 1 , Figure 1This is a flowchart illustrating a method for testing and evaluating the sound insulation performance of a building, as described in an embodiment of this application. The method includes steps S110, S120, S130, and S140, wherein:

[0068] Step S110: Control the sound-emitting devices in the area to be evaluated to emit sound according to preset rules.

[0069] The preset rules include preset paths, sound frequencies, and sound decibel values.

[0070] Specifically, the area to be evaluated can be a newly built building or a commercial premises with sound insulation requirements. The preset rules can be modified as needed. The preset path is determined based on the layout drawings of the area to be evaluated. For example, when the area to be evaluated is a newly built building, the preset path can be determined based on the building's layout drawings so that the sound-generating device can move along the preset path. When determining the preset path, the boundary walls of the area to be evaluated are first determined based on the building's layout drawings, and then the movement range of the sound-generating device is determined based on the boundary walls. For example, when determining the movement route, to reduce the probability of collisions during movement, a certain distance must be maintained between the device and the wall. The specific distance can be determined based on the specifications of the sound-generating device; this embodiment does not impose a specific limitation, as long as it reduces the probability of collisions during movement.

[0071] When evaluating the sound insulation performance of a building, the area to be evaluated is divided in advance. When evaluating the sound insulation performance of a newly built building, multiple rooms can be planned as multiple areas to be evaluated. For example, room A and room B can be divided into one area to be evaluated, and this area is named area AB. After the evaluation of area AB is completed, the sound-emitting and sound-receiving equipment will continue to evaluate area BC or area CD. Since the factor for evaluating the sound insulation performance of a building in this embodiment is the wall, the premise for dividing the area to be evaluated is that the two rooms have at least one common wall.

[0072] The preset decibel value can be determined by pre-collecting sound data from the area to be evaluated, such as collecting noise data near a newly built building, to determine the decibel value in the environment where the building is located, and then determining the decibel value for the sound emission during the evaluation based on the sound decibel value in the environment of the area to be evaluated. The preset sound emission duration can control the sound-emitting device to stop automatically. The preset sound emission duration is not specifically limited in this embodiment and can be modified according to needs.

[0073] Step S120: Receive the live audio sent by the recording device. The live audio is the live audio collected after the sound-emitting device emits sound.

[0074] Specifically, the location of the recording device and the sound-emitting device differs. For example, when evaluating the sound insulation performance of a newly built building, sound-emitting device A moves along a preset path in room one and emits sound at a preset decibel level, while recording device B records the sound in room two. The sound emitted by sound-emitting device A can be transmitted through the wall between room A and room B. The on-site audio is the audio received by the recording device in room B.

[0075] Step S130: Determine the decibel value of the on-site audio based on the on-site audio.

[0076] Specifically, when an electronic device receives the live audio sent by a recording device, it can determine the live decibel value of the live audio based on a decibel detection algorithm.

[0077] Step S140: When the on-site decibel value exceeds the preset standard sound insulation decibel value, it is determined that the sound insulation performance of the area to be evaluated is abnormal and abnormal information is generated.

[0078] The abnormal information includes at least the location of the area to be evaluated and the factors that induce the abnormality.

[0079] Specifically, according to sound insulation standards for civil and industrial buildings: a sound level between 30-40 decibels is considered a relatively quiet environment; a sound level exceeding 50 decibels can affect sleep and rest; a sound level above 70 decibels can affect speech; and prolonged exposure to environments with sound levels above 90 decibels can lead to hearing loss. The preset standard sound insulation decibel values ​​are determined based on these standards for civil and industrial building design.

[0080] If the on-site decibel value exceeds the preset standard sound insulation decibel value, it is determined that the sound insulation performance of the area to be evaluated is abnormal, and an anomaly investigation is carried out in the area to be evaluated. Anomaly information is generated based on the anomaly investigation results. When conducting anomaly investigation at the site to be evaluated, the anomaly inducing factors can be determined by detecting the wall thickness and the building material of the wall.

[0081] In this embodiment, by controlling the sound source device in the area to be evaluated to emit sound at a preset frequency along a preset movement route and at a preset decibel value, the sound receiving device can collect audio and transmit the collected on-site audio to the electronic device. After receiving the on-site audio sent by the sound receiving device, the electronic device determines the on-site decibel value corresponding to the on-site audio. When the on-site decibel value is higher than the preset standard sound insulation decibel value, it is determined that the sound insulation performance of the area to be evaluated is abnormal, and abnormal information is generated. By controlling the sound emitting device and the sound receiving device to evaluate the building sound insulation performance of the area to be evaluated, the work efficiency is improved and the workload of relevant personnel is reduced.

[0082] Furthermore, before determining the on-site decibel value of the on-site audio in step S130 based on the on-site audio, the method further includes: performing noise reduction processing on the on-site audio.

[0083] Specifically, the background noise of the live audio can be removed by spectral subtraction. As the name suggests, spectral subtraction is a signal processing method in the frequency domain. Its basic idea is to extract the spectrum of the signal itself and the spectrum of the live audio, obtain the spectrum of the denoised live audio by the difference between the two, and finally use Fourier transform to determine the denoised live audio.

[0084] In another possible implementation, the acquired live audio can be compared with the audio emitted by the sound-emitting device. Abnormal audio that does not belong to the sound-emitting device is recorded, and a canceled audio with the opposite waveform to the abnormal audio is generated. The canceled audio is used to cancel the abnormal audio in order to perform noise reduction processing on the live audio.

[0085] In this embodiment of the application, by performing noise reduction processing on the on-site audio, the interference of other factors on the on-site audio is reduced, thereby improving the accuracy of building sound insulation detection and evaluation.

[0086] Furthermore, in step S130, the on-site decibel value of the on-site audio is determined based on the on-site audio, specifically including steps S1301 (not shown in the attached figure), S1302 (not shown in the attached figure), and S1303 (not shown in the attached figure), wherein:

[0087] Step S1301: Generate an audio waveform diagram based on the on-site audio.

[0088] Specifically, the starting and ending points of the live audio are determined. Audio feature vectors are extracted and stored starting from the sound starting point. Storage ends when the ending point of the live audio is detected. Based on the extracted feature vectors, a waveform curve coordinate system is established. The coordinates of each audio point are determined on the waveform curve coordinate system, and the coordinates of each coordinate point are connected in order from left to right to form an audio waveform diagram over a period of time.

[0089] Step S1302: Determine the average decibel value within the preset time period based on the audio waveform diagram.

[0090] Step S1303: Determine the average decibel value as the on-site decibel value.

[0091] Specifically, the on-site audio is visualized to form a waveform diagram. The waveform diagram allows for a more intuitive observation of the decibel value of the on-site audio. The waveform diagram is used to determine the decibel value corresponding to different time points. The average decibel value is calculated using the decibel values ​​at different times. The average decibel value is then determined as the on-site decibel value.

[0092] Since the sound-emitting device moves within the sound-emitting time period, the position of the sound-emitting device is different at different times. When the sound-emitting device emits the same decibel value, the on-site decibel value received by the sound-receiving device at different times is also different. The position of the sound-receiving device is fixed. Therefore, using the average decibel value within a preset time period as the on-site decibel value can improve the accuracy of sound insulation performance testing and evaluation. The preset time period is the time period from the start to the end of the on-site audio.

[0093] In this embodiment, an audio waveform diagram corresponding to the on-site audio is generated through on-site audio. The audio waveform diagram can more intuitively display the decibel value generated by the on-site audio. Based on different decibel values, the average decibel value within a preset time period is determined, and the average decibel value is determined as the on-site decibel value. By using the average decibel value to determine the on-site decibel value, the accuracy of the detection results is improved.

[0094] Furthermore, in step S140, when the on-site decibel value exceeds the preset standard sound insulation decibel value, it is determined that the sound insulation performance of the area to be evaluated is abnormal and abnormal information is generated. Specifically, this may include steps S1401 (not shown in the attached figure), S1402 (not shown in the attached figure), and S1403 (not shown in the attached figure), wherein:

[0095] Step S1401: When the on-site decibel value exceeds the preset standard sound insulation decibel value, the thickness of the wall in the area to be evaluated is measured to obtain the wall thickness value.

[0096] Step S1402: Based on the wall thickness value, determine whether the wall in the area to be evaluated meets the building standards. If the wall thickness value does not meet the building standards, then determine the inducing factor in the abnormal information as abnormal wall thickness.

[0097] Specifically, when the on-site decibel value is compared with the preset standard sound insulation decibel value, if the on-site decibel value is greater than the preset standard sound insulation decibel value, a thickness measurement command is sent to the receiving device. After receiving the thickness measurement command from the electronic device, the receiving device activates the thickness gauge installed on the receiving device. The type of thickness gauge is not specifically limited in this embodiment, as long as it can measure the thickness of the wall. When the thickness gauge is an X-ray thickness gauge, the principle of the X-ray thickness gauge is based on the intensity attenuation of X-rays when penetrating the object being measured to convert and measure the thickness, that is, to measure the amount of X-rays absorbed by the wall being measured, to calculate the absorbed energy value corresponding to the absorbed X-ray amount based on the energy value of the X-rays, and to determine the thickness value of the wall being measured based on the absorbed energy value.

[0098] When the wall thickness does not meet the building standards, the abnormal wall thickness is identified as one of the inducing causes that the on-site decibel value exceeds the preset standard sound insulation decibel value, and abnormal information is generated.

[0099] When the on-site decibel value does not exceed the preset standard sound insulation decibel value, it is determined that there is no abnormality in the sound insulation performance of the area to be evaluated.

[0100] Step S1403: If the wall thickness meets the building standards, determine whether the wall building material in the area to be evaluated meets the building standards based on the wall building material. If the wall building material does not meet the building standards, determine that the inducing factor in the abnormal information is abnormal wall building material.

[0101] Specifically, the method for determining whether the wall building materials in the area to be evaluated meet the building standards is as follows: photograph the wall to be tested, record the location information of the wall to be tested, generate confirmation information, and send the confirmation information to the terminal device of relevant staff to remind them to conduct on-site sampling and wall material testing.

[0102] The terminal devices of relevant personnel can interact with electronic devices. After the test is completed, the test results are uploaded to the electronic devices. After receiving the test results sent by the terminal devices, the electronic devices determine the inducing factors in the abnormal information and then supplement the abnormal information.

[0103] In this embodiment of the application, when the on-site decibel value exceeds the preset standard sound insulation decibel value, the wall thickness and wall material in the area to be evaluated are detected to generate abnormal information, which makes it easier to intuitively show the abnormal situation in the area to be evaluated.

[0104] Furthermore, to reduce the workload of relevant staff in the testing and evaluation of building sound insulation performance, after the testing and evaluation of the current area to be evaluated is completed, steps Sa (not shown in the attached diagram), Sb (not shown in the attached diagram), Sc (not shown in the attached diagram), and Sd (not shown in the attached diagram) are also included, wherein:

[0105] Step Sa: Obtain the first position of the sound-emitting device, the first position of the sound-receiving device, and obtain panoramic images of the current evaluation area and the next evaluation area.

[0106] Step Sb: Determine the moving image based on the panoramic image of the current area to be evaluated and the panoramic image of the next area to be evaluated.

[0107] Specifically, the panoramic image of the current evaluation area must contain at least the first position of the sound-emitting device and the first position of the sound-receiving device. The moving image is determined jointly by the panoramic images of the current and next evaluation areas. The process of determining the moving image is as follows: edge extraction is performed on the panoramic images of the current and next evaluation areas, and image matching templates are established. Feature points of the two images to be stitched are identified. Based on the correspondence between the template and the feature points, the parameter values ​​in the mathematical model are calculated, thereby establishing a mathematical transformation model for the two images. Based on the established mathematical transformation model, the two images to be stitched are transformed into the coordinate system of the reference image to complete the unified coordinate transformation. The overlapping areas of the two images to be stitched are then merged to obtain a smooth, stitched moving image.

[0108] Step Sc: Obtain the first path based on the first position of the moving image, the first position of the sound-emitting device, and the moving image.

[0109] Step Sd: Send a first path to the sound-emitting device and the sound-receiving device so that the sound-emitting device and the sound-receiving device can move along the first path.

[0110] Specifically, the first path is the shortest route for the sound-emitting and sound-receiving devices to move from the current area to be evaluated to the next set range to be evaluated. The shortest route can be determined by determining two positions and then using a breadth-first search algorithm or a depth-first search algorithm. The positions can be specific coordinates or a set range.

[0111] Both the sound-generating and sound-receiving devices have positioning chips installed inside. When the sound-generating or sound-receiving device receives the first path sent by the electronic device, it can move according to the first path.

[0112] In this embodiment of the application, a moving image is determined by acquiring panoramic images of the current area to be evaluated and the next area to be evaluated, and a first path is determined based on the first position of the sound-emitting device, the first position of the sound-receiving device, and the moving image, so that the sound-emitting device and the sound-receiving device move along the first path, thereby reducing the workload of relevant personnel in the process of testing and evaluating the sound insulation performance of buildings.

[0113] Furthermore, in step Sd, a first path is sent to the sound-emitting device and the sound-receiving device so that the sound-emitting device and the sound-receiving device can move along the first path, including steps Sd1 (not shown in the figure) and Sd2 (not shown in the figure), wherein:

[0114] Step Sd1: During the movement of the sound-generating device and the sound-receiving device, the second position, movement speed and curvature information of the sound-generating device and the sound-receiving device are acquired in real time to determine the movement direction of the sound-generating device and the sound-receiving device and generate a turning command.

[0115] Step Sd2: Send a turning command to the sound-emitting device and the sound-receiving device to control the sound-emitting device and the sound-receiving device to move along the first path.

[0116] Specifically, the second position refers to the real-time position of the sound-generating and receiving devices during movement. Based on the real-time acquired second position, the movement speed of the sound-generating and receiving devices can be determined. Curvature information is used to represent the degree to which the curve deviates from a straight line; the greater the curvature, the greater the bending of the curve. The turning command of the transport equipment is formed based on the movement speed, direction, and curvature information of the sound-generating and receiving devices. The turning command is sent to the control chip in the sound-generating and receiving devices, which can then control the sound-generating / receiving devices to turn and avoid obstacles.

[0117] In this embodiment, by acquiring the positions of the sound-emitting device and the sound-receiving device in real time during the movement process, the movement speed and curvature information of the sound-emitting device and the sound-receiving device are determined, and the movement direction of the sound-emitting device and the sound-receiving device is determined based on the movement speed and curvature information. Finally, a turning command is generated. After the electronic device sends the generated turning command to the sound-emitting device and the sound-receiving device, it can control the sound-emitting device and the sound-receiving device to move along the first path. By controlling the movement of the sound-emitting device and the sound-receiving device through the turning command, the probability of collision between the sound-emitting device and the sound-receiving device during the movement is reduced.

[0118] Furthermore, this application embodiment provides a method for monitoring and evaluating the sound insulation performance of a building, which further includes: step S1 (not shown in the accompanying drawings) and step S2 (not shown in the accompanying drawings), wherein:

[0119] Step S1: After the recording device reaches the set range of the target location, the positioning information is obtained. The positioning information is emitted after the recording device reaches the set range.

[0120] Step S2: Based on the positioning information, generate a start command and send the start command to the sound-emitting device and the sound-receiving device so that the sound-emitting device and the sound-receiving device can start working after receiving the start command.

[0121] Specifically, the set range is the sound-emitting position and the sound-receiving position of the next area to be evaluated. The specific set range can be modified according to actual needs. After the sound-emitting device and the sound-receiving device reach the set range, they stop moving and generate positioning information. After receiving the positioning information from the sound-emitting device and the sound-receiving device, the electronic device generates a start command based on the positioning information and sends the generated start command decibel value to the control chip of the sound-emitting device and the sound-receiving device to start working.

[0122] In this embodiment, after receiving the positioning information sent by the sound-generating device and the sound-receiving device, a start command is generated to control the sound-generating device and the sound-receiving device to start working, which reduces the workload of relevant personnel in the testing and evaluation process, thereby alleviating the workload of relevant personnel.
