[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Combine the following Figure 1-Figure 4 The detection systems and methods of the present invention are described.

[0024] In order to facilitate a clearer understanding of the technical solutions of the embodiments of the present application, some technical contents related to the embodiments of the present application are first introduced.

[0025] Rollers are key components for the operation of magic carpets. A magic carpet will have dozens or even hundreds of rollers arranged along its route to support the operation of the magic carpet and to bear the weight of skiers (tourists for tourist magic carpets). Once a roller is damaged, the magic carpet will not run smoothly, causing riders to fall, or even causing a group of people to fall. Currently, the monitoring of rollers is mainly done manually on a regular basis. For example, one inspector needs to be responsible for multiple magic carpets, resulting in insufficient manpower and the inability to monitor the operation of rollers in real time.

[0026] The sheave assembly of the support and pressure cable is a key equipment of the passenger ropeway. It plays the role of bearing the wire rope and the sling in the operation of the ropeway. Its design, production, installation and use are subject to strict national standards. New models of wheels even need to pass type tests before they can be manufactured and used. The wheel shaft and bearing are the most vulnerable parts of the support and pressure cable wheel assembly. Once the shaft or bearing is damaged, it will cause the rope pulley to operate poorly or even get stuck, and may eventually cause the shaft to be worn off. There have been several related cases in passenger ropeways at home and abroad. At present, the monitoring of the wheel shaft is mainly carried out through manual inspections, that is, maintenance personnel take a maintenance vehicle through the wheel assembly and visually inspect the operation of the wheel assembly, or climb to the support platform regularly. The manual inspection method consumes manpower and cannot monitor the operation of the wheel assembly in real time.

[0027] Figure 1 It is a schematic diagram of the detection system provided by the present invention, such as Figure 1 As shown, the system includes the following: Calibration module, acquisition module and comparison module; The calibration module is used to calibrate the target voiceprint information of the target device under normal operation; the target device includes a transport magic carpet and / or a cableway; The acquisition module is used to collect the voiceprint information to be detected during the operation of the target device; The comparison module is used to compare the voiceprint information to be detected with the target voiceprint information to obtain the detection result of the target device.

[0035] In one embodiment, when the target device is a cableway, the acquisition module further includes: Cavity conduction amplification module: The cavity conduction amplification module is used to receive the electrical signal sent by the microphone module and amplify it.

[0036] Specifically, the acquisition module of the detection system in the embodiment of the present application also includes a cavity conduction amplification module; wherein the cavity conduction amplification module is used to amplify the electrical signal collected by the microphone module during the process of collecting the voiceprint information during the operation of the cableway, thereby making the collected voiceprint information of the cableway wheel group more accurate, effectively improving the accuracy of the voiceprint information comparison result, and timely and accurately discovering abnormal problems in the operation of the cableway wheel group.

[0037] The system of the above embodiment adds a cavity conduction amplification module to the acquisition module, thereby making the collected voiceprint information of the cableway wheel group more accurate, effectively improving the accuracy of the voiceprint information comparison result, and timely and accurately discovering abnormal problems in the cableway operation process.

[0038] In one embodiment, when the target device is a cableway, the acquisition module is fixed to a wheel set of the cableway.

[0039] Specifically, in the implementation of the present application, the acquisition module is fixed at the wheel group of the cableway, such as fixed at the end of a single wheel axle or the middle axle diameter of two wheels or the middle axle diameter of four wheels, so as to effectively improve the collection effect of the soundprint information during the operation of the cableway wheel group, and thus effectively improve the accuracy of the detection results of the operation status of the cableway wheel group. Optionally, the acquisition module can be fixed at the lower part of the magic carpet roller, so as to realize the collection of the soundprint information during the operation of the magic carpet roller.

[0042] Specifically, the detection system in the embodiment of the present application also includes an environmental noise collection module for collecting environmental noise during the operation of the magic carpet and the cableway. Optionally, when the difference between the voiceprint information to be detected and the target voiceprint information is greater than a threshold, the embodiment of the present application performs noise reduction processing on the voiceprint information to be detected, and re-compares the noise-reduced voiceprint information to be detected with the calibrated voiceprint information, so that a more accurate detection result can be obtained, effectively improving the accuracy of the detection results of the magic carpet roller and the cableway wheel group.

[0043] The system of the above embodiment performs noise reduction processing on the voiceprint information to be detected, and re-compares the noise-reduced voiceprint information to be detected with the calibrated voiceprint information, so as to obtain more accurate detection results, and effectively improve the accuracy of the detection results of the magic carpet roller and the cableway wheel group.

[0044] In one embodiment, the calibration module is further used for: According to the target instruction sent by the user end, the voiceprint information with abnormal detection results is marked as the target voiceprint information under the normal operation of the target device.

That is, when the comparison module determines that the status of the magic carpet roller and the ropeway wheel group is abnormal based on the comparison of the voiceprint information, the staff can further check whether the operating status of the magic carpet roller and the ropeway wheel group is normal; if the staff finds that the operating status of the magic carpet roller and the ropeway wheel group is normal after verification, the user terminal can instruct the calibration module to calibrate the voiceprint information with abnormal detection results as the voiceprint information under normal operation of the target device and add it to the voiceprint information library, so that in the subsequent detection process of the magic carpet roller and the ropeway wheel group, the magic carpet roller and the ropeway wheel group can be detected more accurately based on the updated voiceprint information library, effectively improving the accuracy of the detection results of the magic carpet roller and the ropeway wheel group.

[0046] In the system of the above embodiment, the calibration module calibrates the voiceprint information with abnormal detection results as the voiceprint information under normal operation of the target device according to the target instruction sent by the user terminal, so that in the subsequent detection process of the magic carpet rollers and the cableway wheel group, the magic carpet rollers and the cableway wheel group can be detected more accurately based on the updated voiceprint information library, effectively improving the accuracy of the detection results of the magic carpet rollers and the cableway wheel group.

The storage module is used to store the voiceprint information calibrated by the calibration module. The alarm module is used to send an alarm message to the user terminal when determining that the status of the magic carpet roller and the cableway wheel group is abnormal, so that the fault of the magic carpet roller and the cableway wheel group can be handled in time to improve the safety of the equipment.

[0049] The system of the above embodiment sends an alarm message to the user end when determining that the status of the magic carpet roller and the cableway wheel group is abnormal, so that the failure of the magic carpet roller and the cableway wheel group can be handled in time, effectively improving the safety of the equipment.

Optionally, if the difference between the collected voiceprint information and the calibrated voiceprint information is greater than a threshold, it is determined that the operation status of the magic carpet roller and the cableway wheel group is abnormal, thereby achieving real-time detection of the operation status of the magic carpet roller and the cableway wheel group.

[0054] The method of the above embodiment, by comparing the real-time collected soundprint information of the magic carpet rollers and the cableway wheel assembly with the calibrated soundprint information of the magic carpet rollers and the cableway wheel assembly, can accurately and quickly determine whether there is any abnormality in the operating status of the magic carpet rollers and the cableway wheel assembly, thereby realizing real-time monitoring of the magic carpet rollers and the cableway wheel assembly, effectively saving manpower and improving the detection efficiency of the magic carpet rollers and the cableway wheel assembly.

[0055] Exemplarily, a detection system is provided in the implementation of the present application, including a device end and a user end.

[0056] The device side includes: The calibration module is used to match the voiceprint parameters representing the normal operation status with the passenger ropeway (magic carpet) running speed parameters corresponding to the parameters to synthesize the voiceprint information. Multiple groups of voiceprint information are collected to form a voiceprint information library.

[0057] The voiceprint parameter collection module is composed of a microphone array, a cavity conduction amplification component, and a voiceprint analysis card. The voiceprint collection module is fixed at the sound source of the wheelset shaft by a mounting component. The sound information generated by the operation of the wheelset shaft is collected through the microphone array, and the voiceprint analysis card analyzes the sound information into voiceprint parameters such as sound amplitude and frequency.

[0058] The voiceprint information comparison module is used to compare the voiceprint information collected in real time with the voiceprint information in the voiceprint information database to see if it exceeds the threshold.

[0059] The environmental noise collection module is used to collect environmental sounds for necessary noise reduction processing.

[0060] The storage module is used to cache voiceprint parameters, real-time running speed parameters, voiceprint information, ambient sound, and voiceprint information library, etc.

[0061] The alarm module is used to send out alarm signals in abnormal situations.

[0062] The user end is mainly used to send the real-time operating parameters of the cableway, and display abnormal positions, abnormal voiceprint information, etc.

[0063] The transmission module is used to transmit the alarm signal and voiceprint information to the user end.

[0064] The receiving module is used to receive the real-time operating parameters of the cableway and the supplementary calibration instructions sent by the user end.

[0065] The installation component is used to install the above module at a location convenient for collecting wheel set soundprint parameters.

[0066] Optionally, the specific working principle of the detection system of the present application is as follows: Mechanical equipment, especially shaft equipment, often shows abnormal characteristics in sound when it is worn, unbalanced, loose, lacks lubrication, etc. The detection system of the present application can effectively identify and predict the operating status of the equipment by analyzing these sound signals, including but not limited to the sound amplitude and frequency, so as to realize the advanced fault alarm and preventive maintenance.

[0067] Exemplarily, the working process of the detection system in the implementation of this application is as follows: Figure 4 As shown, the details are as follows: 1. Installation

[0068] The device is installed at a location convenient for collecting the soundprint parameters of rollers and wheels by using mounting components. In a preferred embodiment, to ensure the collection effect, the cavity conduction amplification component of the soundprint parameter collection module is installed at the end of a single wheel axle or the middle shaft diameter portion of two wheels or the middle shaft diameter portion of four wheels.

[0069] 2. Calibration

[0070] After the initial installation, start the ropeway (magic carpet), collect voiceprint parameters at different speeds, match the voiceprint parameters with the real-time speed parameters to synthesize voiceprint information, and collect multiple sets of voiceprint information to form a voiceprint information library such as Figure 3 As shown, the voiceprint information library is stored in the storage module. A preferred embodiment is that the cableway collects voiceprint information at a step length of 1 m / s, and the magic carpet collects voiceprint information at a step length of 0.1 m / s.

[0071] 3. Real-time monitoring

[0072] When the cableway (magic carpet) is running, the voiceprint parameter collection module collects voiceprint parameters in real time and matches them with the running speed parameters. The voiceprint information corresponding to the running speed is retrieved from the voiceprint information library. Through comparison, if the difference does not exceed the threshold, it means that the status is normal and monitoring continues.

[0073] If the difference exceeds the threshold, the ambient sound collected by the ambient noise collection module in real time is retrieved, necessary noise reduction processing is performed, and the sound is compared with the corresponding voiceprint information again. If the difference does not exceed the threshold, it means that the status is normal and monitoring continues; if it still exceeds the threshold, an alarm signal is sent to the user end, and the denoised voiceprint parameters are matched with the corresponding running speed parameters to synthesize the voiceprint information and send it to the user end. All the information involved is cached in the storage module.

[0074] 4. Supplementary calibration

[0075] After receiving the alarm signal and the corresponding voiceprint information, if the user determines that the information represents a normal situation, a supplementary calibration instruction is sent to the device. After receiving the instruction, the device adds the cached voiceprint information to the voiceprint information library.

[0076] The method of the above embodiment can effectively identify and predict the operating status of the equipment by comparing the real-time collected soundprint information of the magic carpet rollers and the cableway wheel group with the calibrated soundprint information of the magic carpet rollers and the cableway wheel group, thereby realizing advanced fault alarm and preventive maintenance.
