Technical Field

[0001] This invention relates to the field of equipment testing technology, and more specifically, to a device, method, storage medium, and electronic device for determining the operating status of equipment. Background Technology

[0002] In industrial environments, it is often necessary to monitor the operating status of equipment. For example, the operating status of equipment can be determined by detecting its voiceprint data. In related technologies, voiceprint detection of the device under test mainly involves the following steps: A voiceprint acquisition module is installed near the device under test, converting the acquired voiceprint data into a digital signal, typically a network signal, and then transmitting it to a backend data center server for intelligent analysis to obtain the results. Figure 1 This is a block diagram of a voiceprint acquisition system in related technologies. Figure 1 The voiceprint acquisition module is responsible for voiceprint acquisition and converting the signal into a digital signal for transmission, resulting in a limited transmission distance. To transmit over longer distances, switching equipment is required, increasing costs and system complexity. Furthermore, the voiceprint acquisition module has many integrated circuits, which increases the failure rate in harsh industrial environments. It is evident that the reliability of the device for determining the operating status in related technologies is low. Moreover, the devices in related technologies cannot analyze the acquired data in real time.

Detailed Implementation

[0039] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0040] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0041] This embodiment provides a device for determining the operating status of a device. Figure 2 This is a structural block diagram of the device for determining the operating status of the equipment according to an embodiment of the present invention, as shown below. Figure 2 As shown, the device includes:

[0042] The first voiceprint acquisition module 202 is disposed in the first area where the first device under test is located. The first voiceprint acquisition module 202 includes a first voiceprint sensor 20202 for converting a first voiceprint signal into a first voltage signal, and a first signal conversion module 20204 for converting the first voltage signal into a first current signal. The first signal conversion module 20204 is connected to the first voiceprint sensor 20202. The first voiceprint signal is the voiceprint signal generated by the first device under test.

[0043] The data analysis module 204 is connected to the first signal conversion module 20204 via a cable. The data analysis module 204 includes a second signal conversion module 20402 for converting a first current signal into a second voltage signal, and a target processing module 20404 for determining a first analysis result based on the second voltage signal. The first analysis result represents the operating status of the first device under test.

[0044] In the above embodiments, the device for determining the operating status of the device includes a first acoustic signature acquisition module and a data analysis module. The first acoustic signature acquisition module includes a first acoustic signature sensor for converting a first acoustic signature signal generated by the first device under test into a first voltage signal, and a first signal conversion module for converting the first voltage signal into a first current signal. The first signal conversion module is connected to the data analysis module via a cable. The data analysis module includes a second signal conversion module for converting the first current signal into a second voltage signal, and a target processing module for determining the operating status of the first device under test based on the second voltage signal. In this embodiment, the first voltage signal is converted into a first current signal by the first signal conversion module and transmitted to the data analysis module via a cable, thereby avoiding the need for further processing of the acoustic signature signal in related technologies. The direct conversion of the acoustic fingerprint sensor's acquired signal into a digital signal for transmission results in a short transmission distance. This also avoids the increased cost associated with adding switching equipment for longer transmission distances, as required in related technologies. This embodiment reduces the cost of long-distance transmission. Furthermore, the acoustic fingerprint acquisition module in this embodiment has a simple circuit, making it suitable for harsh working environments. This avoids the increased failure rate and lower reliability issues common in related technologies due to the complexity of integrated circuits in harsh conditions. In addition, the target processing module in the data analysis module of this embodiment can determine the operating status of the first tested device based on the second voltage signal, achieving real-time analysis and result output after acoustic fingerprint signal acquisition. This avoids the lack of real-time data analysis in related technologies, thereby improving detection efficiency. This embodiment solves the problems of low reliability of device operating status determination devices and poor real-time data analysis in related technologies.

[0045] In an optional embodiment, the target processing module includes: an analog-to-digital sampling module connected to the second signal conversion module, the analog-to-digital sampling module being configured to sample the second voltage signal into a target digital signal; and a processor connected to the analog-to-digital sampling module, the processor being configured to determine the first analysis result based on the target digital signal.

[0046] In the above embodiment, the target processing module includes an analog-to-digital sampling module and a processor. The analog-to-digital sampling module samples the second voltage signal to obtain a target digital signal, while the processor analyzes the target digital signal to obtain a first analysis result, i.e., analyzing the target digital signal to determine the operating status of the first device under test, such as whether the first device under test is operating abnormally. This embodiment achieves the goal of sampling and analyzing the second voltage signal through the target processing module to determine the operating status of the first device under test, i.e., it achieves the goal of real-time analysis and real-time result output after acquiring the acoustic signature signal of the first device under test, avoiding the problem of insufficient real-time data analysis in related technologies, thereby improving detection efficiency.

[0047] In an optional embodiment, the processor includes a network communication component for establishing a communication connection with a data center device, wherein the first analysis result is information transmitted to the data center device through the communication connection.

[0048] In the above embodiments, the first analysis result is transmitted to the data center equipment via a network communication component, for example, the first analysis result is transmitted to the data center equipment of the safety production monitoring center via a network.

[0049] In an optional embodiment, the processor further includes: a computing unit configured to process the target digital signal through a target network model to obtain the first analysis result, wherein the target network model is a network model obtained by training an initial network model using sample voiceprint data, the sample voiceprint data includes sample digital signals obtained by sampling sample voltage signals, and the sample voltage signals include voltage signals converted from voiceprint signals generated by the first device under test when it is in different operating states.

[0050] In the above embodiments, the target network model can be a network model obtained by training the initial network model using sample voiceprint data. For example, the sample voiceprint data can be a sample digital signal obtained by sampling the voltage signal converted from the voiceprint signal generated by the first device under test when it is in different operating states. The voiceprint signal can be generated by the first device under test when it is in normal operation or by the first device under test under various abnormal states. In this way, after the first voiceprint signal generated by the first device under test is collected to obtain the first voltage signal, the first voltage signal is converted into a first current signal, the first current signal is converted into a second voltage signal, and the second voltage signal is sampled to obtain the target digital signal. By processing the target digital signal through the above target network model, the first analysis result can be obtained.

[0051] In an optional embodiment, the first signal conversion module includes a voltage-to-current module configured to linearly convert the first voltage signal into the first current signal.

[0052] In the above embodiments, the voltage-to-current module can linearly convert the first voltage signal into a first current signal. For example, assuming that the range of the first voltage signal obtained by the first voiceprint sensor is 0 to 3V, and according to the needs of actual applications, it is necessary to control the first current signal within a certain range, such as 0-20mA. The purpose of linearly converting the first voltage signal into the first current signal can be achieved by designing a voltage-to-current module.

[0053] In an optional embodiment, the system further includes: a second voiceprint acquisition module, which is disposed in a second area where the second device under test is located. The second voiceprint acquisition module includes a second voiceprint sensor for converting a second voiceprint signal into a third voltage signal, and a third signal conversion module for converting the third voltage signal into a second current signal. The third signal conversion module is connected to the second voiceprint sensor, and the second voiceprint signal is a voiceprint signal generated by the second device under test. The second area is different from the first area. The data analysis module is connected to the third signal conversion module via a cable. The data analysis module further includes a fourth signal conversion module for converting the second current signal into a fourth voltage signal. The fourth signal conversion module is connected to the target processing module. The target processing module is further configured to determine a second analysis result based on the fourth voltage signal, and the second analysis result represents the operating status of the second device under test.

[0054] In the above embodiments, the voiceprint processing device may further include a second voiceprint acquisition module. The second voiceprint acquisition module is located in the second area where the second device under test is situated. The second voiceprint acquisition module has the same module composition and working principle as the first voiceprint acquisition module in the aforementioned embodiments. Similarly, the second voiceprint acquisition module includes a second voiceprint sensor for converting the second voiceprint signal into a third voltage signal, and a third signal conversion module for converting the third voltage signal into a second current signal. The data analysis module is also connected to the third signal module via a cable. The data analysis module further includes a fourth signal conversion module for converting the second current signal into a fourth voltage signal. The target processing module can determine the operating status of the second device under test based on the fourth voltage signal. That is, when performing voiceprint signal detection on multiple devices under test, only a corresponding voiceprint acquisition module needs to be configured for each device under test, while the aforementioned target processing module can be shared. This embodiment enables the simultaneous analysis of multiple devices under test, providing convenience for deployment and construction in industrial settings.

[0055] In an optional embodiment, the system further includes: a third voiceprint acquisition module, which is disposed within the first area where the first device under test is located and at a different location from the first voiceprint acquisition module. The third voiceprint acquisition module includes a third voiceprint sensor for converting a third voiceprint signal into a fifth voltage signal, and a fifth signal conversion module for converting the fifth voltage signal into a third current signal. The fifth signal conversion module is connected to the third voiceprint sensor. The third voiceprint signal is a voiceprint signal generated by the first device under test at the location of the third voiceprint acquisition module, and the first voiceprint signal is a voiceprint signal generated by the first device under test at the location of the first voiceprint acquisition module. The data analysis module is connected to the fifth signal conversion module via a cable. The data analysis module further includes a sixth signal conversion module for converting the third current signal into a sixth voltage signal. The sixth signal conversion module is connected to the target processing module, and the target processing module is configured to determine the first analysis result based on the second voltage signal and the sixth voltage signal.

[0056] In the above embodiments, the voiceprint processing device may further include a third voiceprint acquisition module. The third voiceprint acquisition module may be set in the first area where the first device under test is located, and in a different position from the first voiceprint acquisition module. For example, the first voiceprint acquisition module and the third voiceprint acquisition module may be set in different positions of the first device under test. The third voiceprint acquisition module has the same module composition and working principle as the first voiceprint acquisition module, that is, it acquires multiple voiceprint signals for one device under test. Similarly, the third voiceprint acquisition module includes a third voiceprint sensor for converting the third voiceprint signal into a fifth voltage signal, and a fifth signal conversion module for converting the fifth voltage signal into a third current signal. The data analysis module is also connected to the fifth signal module through a cable. The data analysis module also includes a sixth signal conversion module for converting the third current signal into a sixth voltage signal. The target processing module can determine the operating status of the first device under test based on the second voltage signal and the sixth voltage signal. In other words, for a device under test that requires multiple acoustic signature acquisition modules to be set up in multiple directions, the output signal of each acoustic signature acquisition module can be connected to the same data analysis module at the same time. The aforementioned target processing module can be shared, which provides convenience for industrial site deployment and construction.

[0057] In an optional embodiment, the system further includes: a first alarm module connected to the data analysis module, the first alarm module being configured to issue an alarm signal, the alarm signal being issued when the first analysis result is received and the first analysis result indicates that the operating state of the first device under test is abnormal.

[0058] In the above embodiments, the voiceprint processing device may further include a first alarm module. The first alarm module will issue an alarm signal when it receives a first analysis result indicating that the operating state of the first device under test is abnormal. That is, in practical applications, when the first analysis result is determined and an abnormality is found in the first device under test based on the first analysis result, corresponding linkage processing can be performed, such as audible and visual alarms, or a prompt to initiate shutdown and maintenance. In practical applications, an alarm signal can also be issued at the data center device when the first analysis result is transmitted to the data center device (or server, or backend).

[0059] In an optional embodiment, the first signal conversion module includes: a first operational amplifier and a first transistor, wherein the first output terminal of the first operational amplifier is connected to the base of the first transistor through a first resistor, the first non-inverting input terminal of the first operational amplifier is connected to the output terminal of the first voiceprint sensor through a second resistor, the first inverting input terminal of the first operational amplifier is grounded through a third resistor and connected to the emitter of the first transistor through a fourth resistor, the first non-inverting input terminal of the first operational amplifier is connected to the first end of a sixth resistor through a fifth resistor, and the second end of the sixth resistor is connected to the emitter of the first transistor, and the collector of the first transistor is connected to the input power supply through a seventh resistor; the first end of the sixth resistor is the output terminal of the first signal conversion module.

[0060] In the above embodiments, the first signal conversion module can convert the acoustic voltage signal (such as the aforementioned first voltage signal, third voltage signal, or fifth voltage signal) into a current signal (such as the aforementioned first current signal, second current signal, or third current signal), and can linearly convert the voltage signal into a current signal. By using analog current signal transmission, the transmission distance can be extended and interference can be reduced. Compared with the problem of high cost caused by the need to add switching equipment to achieve long-distance transmission in related technologies, this embodiment achieves the goal of reducing the cost of long-distance transmission.

[0061] In an optional embodiment, the second signal conversion module includes: a second operational amplifier, the second non-inverting input terminal of the second operational amplifier being connected to the output terminal of the first signal conversion module via the cable and grounded via an eighth resistor; the second inverting input terminal of the second operational amplifier being grounded via a ninth resistor, connected to the output terminal of the second operational amplifier via a tenth resistor, and connected to the output terminal of the second operational amplifier via a first capacitor; the output terminal of the second operational amplifier is the output terminal of the second signal conversion module and is connected to the target processing module.

[0062] In the above embodiments, the second signal conversion module can convert the current signal into a voltage signal. For example, the first voiceprint sensor converts the collected first voiceprint signal into a first voltage signal, and then the first signal conversion module converts the first voltage signal into a first current signal. Then the second signal conversion module converts the first current signal into a second voltage signal. In practical applications, the second voltage signal is very close to the first voltage signal, which achieves the purpose of extending the transmission distance while ensuring that the signal is not distorted.

[0063] In an optional embodiment, the first voiceprint acquisition module further includes a first power supply module; the target processing module further includes a second power supply module and a current detection module; wherein the second power supply module is connected to the processor, and the second power supply module is connected to the first power supply module through the current detection module; the current detection module is configured to transmit a first feedback signal to the second power supply module when it detects that the output current of the second power supply module is greater than or equal to a predetermined threshold, wherein the first feedback signal is used to control the second power supply module to stop supplying power; the first power supply module is configured to supply power to the first voiceprint sensor and the first signal conversion module, and the second power supply module is configured to supply power to the second signal conversion module, the analog-to-digital sampling module, and the processor.

[0064] In the above embodiment, the second power module supplies power to the second signal conversion module, the analog-to-digital sampling module, and the processor. The second power module is connected to the first power module via a current detection module. The current detection module detects the output current of the second power module, and when the current detection module detects that the output current of the second power module is greater than or equal to a predetermined threshold, it transmits a first feedback signal to the second power module to control it to stop supplying power in a timely manner. Optionally, the current detection module feeds back the detected output current value of the second power module to the processor. The processor then compares the output current value of the second power module with the input current collected by the second signal conversion module. When the difference between them is greater than a preset value, the processor outputs a control signal to control the second power module to stop supplying power. Optionally, in practical applications, the processor can also output fault information. Through this embodiment, by detecting the current output of the second power module, fault alarms and power-off processing can be performed in a timely manner when abnormalities occur.

[0065] Obviously, the embodiments described above are only some embodiments of the present invention, and not all embodiments. The present invention will be specifically described below with reference to the embodiments.

[0066] Figure 3 This is an example diagram of the voiceprint acquisition and intelligent analysis system according to an embodiment of the present invention, such as... Figure 3As shown, the system includes a voiceprint acquisition module and a sampling and intelligent analysis module (corresponding to the aforementioned data analysis module). The composition of the system and the working principle of some modules are explained below.

[0067] The voiceprint acquisition module in this system (such as Figure 3 (302, 304) only includes a voiceprint sensor (such as...) Figure 3 30202 and 30402 correspond to the aforementioned first, second, or third voiceprint sensor and V / I module (such as...). Figure 3 In modules 30204 and 30404 (corresponding to the aforementioned first, third, or fifth signal conversion modules), the voiceprint sensor converts the voiceprint signal (0~150KHz signal) into a voltage signal, and the V / I module converts the voiceprint voltage signal into a current signal. During the design, the voiceprint voltage signal is limited to the range Vmin~Vmax (Vmin is the minimum value of the voiceprint voltage signal output by the voiceprint sensor, and Vmax is the maximum value). The V / I conversion module linearly converts the voiceprint voltage signal within the Vmin~Vmax range into a current signal within the Imin~Imax range (Imin is the minimum value of the voiceprint current signal output by the voiceprint sensor, and Imax is the maximum value), such as... Figure 4 As shown, Figure 4 This is a schematic diagram of voltage / current linear conversion according to an embodiment of the present invention. For example, a 0V~3V acoustic voltage signal can be converted into a 0~20mA acoustic current signal.

[0068] The principle of V / I module implementing V / I conversion is as follows: Figure 5 As shown. Vin is the voiceprint voltage signal, and Iout is the voiceprint current signal. The voiceprint acquisition module itself requires a certain current Inormal to operate normally. Therefore, when the voiceprint signal is 0V, the minimum output current of the V / I conversion module needs to be set to Inormal to ensure that the voiceprint acquisition module operates normally. In actual design, a certain margin needs to be reserved. The minimum output current is Imin > Inormal. The final V / I module conversion relationship is Iout = Vin / R + Vref / R ( Figure 5 (Vref is not shown in the image), R can be... Figure 5 R6 in the equation, where Imin = Vref / R. Figure 5The first output terminal of the first operational amplifier LM1 is connected to the base of the first transistor Q1 through the first resistor R1. The first non-inverting input terminal of the first operational amplifier is connected to the output terminal of the aforementioned first voiceprint sensor through the second resistor R2. The first inverting input terminal of the first operational amplifier is grounded through the third resistor R3 and connected to the emitter of the first transistor through the fourth resistor R4. The first non-inverting input terminal of the first operational amplifier is connected to the first end of the sixth resistor R6 through the fifth resistor R5, and the second end of the sixth resistor is connected to the emitter of the first transistor. The collector of the first transistor is connected to the input power supply through the seventh resistor R7. The first end of the sixth resistor is the output terminal of the aforementioned first signal conversion module.

[0069] The sampling and intelligent analysis module in this system (such as...) Figure 3 306, corresponding to the aforementioned data analysis module, includes I / V modules (such as...). Figure 3 30602, 30604), ADC acquisition and digitization module (such as Figure 3 30606 (corresponding to the aforementioned analog-to-digital sampling module) and processor (such as...) Figure 3 (30608), where, after the current is transmitted through the cable, the I / V module (corresponding to the aforementioned second signal conversion module, or fourth signal conversion module, or sixth signal conversion module) converts the acoustic current signal into a voltage signal, which is then sampled and digitized by the ADC (such as...). Figure 3 After (30606), the voiceprint signal is converted from an analog signal to a digital signal for the processor (such as...). Figure 3 (30608) is used for digital processing, model training, and intelligent analysis.

[0070] The principle of I / V module implementing I / V conversion is as follows: Figure 6 As shown. The second non-inverting input of the second operational amplifier LM2 is connected to the output of the aforementioned first signal conversion module via a cable and grounded through the eighth resistor R8. The second inverting input of the second operational amplifier is grounded through the ninth resistor R9, connected to the output of the second operational amplifier through the tenth resistor R10, and connected to the output of the second operational amplifier through the first capacitor C1. The output of the second operational amplifier is the output of the aforementioned second signal conversion module and is connected to the aforementioned target processing module. Figure 6 Vout=Iin R or Vout=2 Iin R (if the signal amplitude is too small, perform some multiplication on the signal), R can be... Figure 6 R8 in the middle.

[0071] When deploying equipment in an industrial setting, a single device under test may require one acoustic signature acquisition module, or acoustic signature acquisition modules may be needed in different locations. All of these modules can be simultaneously connected to the same sampling and intelligent analysis module, allowing analysis of one device under test or multiple devices under test (e.g., ...). Figure 3 (Device under test 1, Device under test n).

[0072] Figure 7 It is the power supply frame of the voiceprint acquisition system in related technologies. Figure 1 ,like Figure 7 As shown, the AC power is converted into DC power by the power adapter to power the voiceprint acquisition module. Figure 7 The diagram shows the main power supply methods in related technologies, requiring two wires for power (positive and negative), two wires for current transmission, or eight wires for network transmission. In these technologies, PoE power supply can be used for network signal transmission. For example... Figure 8 As shown, a network cable with 8 wires is also required.

[0073] Figure 9 This is an example diagram of an optional power supply scheme in an embodiment of the present invention, wherein the voiceprint acquisition module and the sampling and intelligent analysis module are both powered by separate power adapters, and the mains power is converted into DC power through the power adapter to power the voiceprint acquisition module and the sampling and intelligent analysis module.

[0074] In the power supply solutions of the aforementioned related technologies and Figure 9 In the optional power supply schemes shown in this application, the voiceprint acquisition module requires a separate power adapter or PoE power supply, which necessitates the addition of a PSE power supply module and a PD power receiving module. Using a separate adapter increases the complexity of on-site wiring, introduces more uncertainties, and fails to provide intelligent power supply and protection functions. PoE power supply requires additional modules, increasing cost and system complexity, and the voiceprint acquisition module has a large number of integrated circuits, which increases the failure rate in harsh industrial environments.

[0075] For the above power supply methods, the voiceprint acquisition module requires a minimum of 4 wires and a maximum of 10 wires.

[0076] This invention provides a power supply scheme for an intelligent voiceprint acquisition and analysis system, such as... Figure 10 As shown, Figure 10 This is a block diagram of the voiceprint acquisition and intelligent analysis system according to an embodiment of the present invention. Figure 10 The voiceprint acquisition module 302 in the middle (such as Figure 10The middle voiceprint acquisition module 1) includes a voiceprint sensor 30202, a V / I module 30204 and a first power supply module 30206 (corresponding to the aforementioned first power supply module). The first power supply module 30206 receives power from the constant voltage line and converts it into a corresponding voltage to power the voiceprint sensor and the V / I module (corresponding to the aforementioned first signal conversion module), ensuring that the voiceprint acquisition module works normally.

[0077] When the acquisition and intelligent analysis module 306 is powered on, the processor controls the power module output through the control signal. The power output passes through the current monitoring module 30612 (corresponding to the aforementioned current detection module) and then reaches the voiceprint acquisition module 302 through the cable. The current returns to the acquisition and intelligent analysis module 306 through the current line.

[0078] When the current monitoring module detects that the output current of the second power module is greater than Imax (corresponding to the aforementioned predetermined threshold), the current monitoring module hardware triggers a feedback signal to shut down the power module output (this action is completed in nanoseconds), and at the same time, it feeds back the feedback signal to the processor, displays the fault code and fault information, and also outputs a control signal to shut down the power output module; or when the current monitoring module detects that the difference between the output current of the second power module 30610 and the input current collected by the I / V module 30602 is greater than Inormal (e.g., 2mA, or 4mA, or other values), the processor outputs a fault code and fault information, and at the same time outputs a control signal to shut down the power module output.

[0079] When the aforementioned voiceprint acquisition module is functioning normally, its minimum output current is Imin (Imin > Inormal > 0), and its maximum value is Imax. After the transmitted current signal is converted by the I / V module 30602, calculated by the ADC acquisition and digitization module 30606 and the processor 30608, if its value exceeds the normal range of Imin to Imax, a system fault can be considered. For example, if the acquired current is 0, it can be considered a line break; the power output should be disconnected, and the corresponding fault code and information should be displayed. If it is within the range of 0 to Imin, the module can be considered malfunctioning; the power output should be disconnected, and the corresponding fault code and information should be displayed. If the acquired current is between Imin and Imax, the system is considered to be functioning normally and will continue to operate.

[0080] The above current conversion relationship is based on the fact that the output current of the V / I module comes directly from the constant voltage power supply. If the output current of the V / I module comes from the converted voltage power supply inside the voiceprint acquisition module, the current parameters at each judgment point need to be adjusted accordingly.

[0081] This embodiment proposes a completely different voiceprint acquisition and intelligent analysis device and solution from existing solutions. It features long transmission distance, ensures data integrity, maintains signal integrity, and is less susceptible to interference. Furthermore, the improved voiceprint acquisition module is simpler and more reliable, thus reducing subsequent maintenance costs.

[0082] In the above embodiments, the voiceprint signal is transmitted using current. The voiceprint acquisition module converts the voiceprint signal into a current signal as an independent module, and the conversion method is linear. The intelligent analysis module integrates the I / V conversion module and can analyze multiple voiceprint signals simultaneously. The voiceprint signal can correspond to multiple devices under test or the same device.

[0083] Compared with the solutions in related technologies, the embodiments of the present invention have the following advantages: 1) The voiceprint acquisition module is simple, compact, highly reliable, and easy to deploy; 2) It uses analog current signal transmission, which has a long transmission distance, is not easily interfered with, and can cover the on-site factory area; 3) It uses analog signal transmission, which is distortion-free, delay-free, and has good synchronization effect; 4) The sampling and intelligent analysis module performs real-time analysis on-site and outputs results in real time, and the results are synchronized to the data center.

[0084] This embodiment also provides a method for determining the operating status of a device. Figure 11 This is a flowchart of a method for determining the operating status of a device according to an embodiment of the present invention, such as... Figure 11 As shown, the process includes the following steps:

[0085] Step S1102: The first voiceprint sensor converts the first voiceprint signal into a first voltage signal, wherein the first voiceprint signal is the voiceprint signal generated by the first device under test.

[0086] Step S1104: The first signal conversion module converts the first voltage signal into a first current signal;

[0087] Step S1106: The second signal conversion module converts the first current signal into a second voltage signal;

[0088] In step S1108, the target processing module determines a first analysis result based on the second voltage signal, wherein the first analysis result represents the operating status of the first device under test.

[0089] Through the above steps, the acoustic signature signal generated by the first device under test is converted into a first voltage signal, then into a first current signal, and finally into a second voltage signal. The second voltage signal is then analyzed to obtain a first analysis result, which determines the operating status of the first device under test. In this embodiment, by converting the first voltage signal into a first current signal, it can be transmitted to the analysis module via cable. This avoids the problem of short transmission distance caused by directly converting the acquired signal into a digital signal for transmission in related technologies, and also avoids the problem of increased costs due to the need for additional switching equipment for longer transmission distances. This embodiment reduces the cost of long-distance transmission. It also avoids the problem of increased failure rate and low reliability in harsh working conditions caused by the complexity of the acoustic signature acquisition module due to the large number of integrated circuits in related technologies. Furthermore, this embodiment can determine the operating status of the first device under test based on the second voltage signal, achieving real-time on-site analysis and real-time result output after acquiring the acoustic signature signal. This avoids the problem of insufficient real-time data analysis in related technologies, thereby improving detection efficiency.

[0090] The entity performing the above steps can be a voiceprint acquisition and analysis system, such as a system including the first voiceprint sensor, the first signal conversion module, the second signal conversion module and the target processing module, or other devices or equipment with data acquisition and analysis functions, but not limited thereto.

[0091] In an optional embodiment, the target processing module includes an analog-to-digital sampling module and a processor. The target processing module determines a first analysis result based on the second voltage signal, including: the analog-to-digital sampling module sampling the second voltage signal into a target digital signal; and the processor determining the first analysis result based on the target digital signal. In this embodiment, the second voltage signal can be sampled first to form a target digital signal. Then, the operating state of the first device under test can be determined based on the target digital signal. For example, the above operation can be described using a voiceprint acquisition intelligent analysis system. The voiceprint acquisition intelligent analysis system may include the processor mentioned above. The processor may be configured to process the target digital signal through a target network model to obtain a first analysis result. The target network model may be a network model obtained by training an initial network model using sample voiceprint data. For example, the sample voiceprint data may be a sample digital signal obtained by sampling the voltage signal converted from the voiceprint signal generated by the first device under test when it is in different operating states. The voiceprint signal may be generated by the first device under test when it is in normal operation or when it is in various abnormal states. Thus, after the first voiceprint signal generated by the first device under test is acquired to obtain the first voltage signal, the first voltage signal is converted into a first current signal, the first current signal is converted into a second voltage signal, and the second voltage signal is sampled to obtain the target digital signal. By processing the target digital signal through the target network model, the first analysis result can be obtained.

[0092] In an optional embodiment, the first voiceprint acquisition module includes a first voiceprint sensor, a first signal conversion module, and a first power supply module; the data analysis module includes a second signal conversion module and the target processing module; the target processing module further includes a second power supply module and a current detection module; wherein the second power supply module is connected to the processor, and the second power supply module is connected to the first power supply module through the current detection module; the processor determines the first analysis result based on the target digital signal, including: when the processor determines that the output current value of the second power supply module and the sampled current value meet a predetermined condition, the processor determines the first analysis result based on the target digital signal, wherein the output current value of the second power supply module is detected by the current detection module, and the sampled current value is calculated by the processor based on the target digital signal. In this embodiment, when it is determined that the output current value of the second power supply module and the sampled current value meet a predetermined condition, the target digital signal is analyzed to determine the first analysis result. For example, the processor can obtain the output current value of the second power supply module detected by the current detection module, and can also analyze the target digital signal (such as the second voltage signal) sampled by the analog-to-digital sampling module to obtain the sampled current value, combined with... Figure 10 When the difference between the output current value of the second power module and the sampled current value is determined to be within a certain range, for example, between 0 and Inormal (e.g., Inormal is 2mA, 4mA, or other values), if it exceeds this range, a fault may exist, and in practical applications, power can be cut off in a timely manner. Through this embodiment, by monitoring the output current value of the second power module and analyzing the target digital signal when a predetermined condition is met between the output current value and the sampled current value to determine the first analysis result, the purpose of fault monitoring is achieved, thereby improving the safety of equipment operation.

[0093] In an optional embodiment, the method further includes: when the processor determines that the output current value of the second power module and the sampled current value do not meet the predetermined condition, transmitting a target control signal to the second power module to control the second power module to stop supplying power; and / or when the processor determines that the output current value of the second power module and the sampled current value do not meet the predetermined condition, issuing a prompt message, wherein the prompt message is used to indicate the fault type of the first device under test. In this embodiment, when it is determined that the output current value of the second power module and the sampled current value do not meet the predetermined condition, the processor transmits a target control signal to the second power module to stop supplying power; optionally, the processor may also issue a prompt message to indicate the possible fault type of the first device under test. Through this embodiment, the purpose of timely controlling the power module to stop supplying power and issuing fault prompt messages when an anomaly is determined is achieved, thereby improving the safety of the system.

[0094] The present invention will now be described in conjunction with specific embodiments. Figure 12 This is a flowchart example of how the processor processes voiceprint data according to an embodiment of the present invention. Figure 1 The process includes:

[0095] S1202, the processor sends a control signal to control the output of the power module (corresponding to the aforementioned second power module);

[0096] S1204, the current detection module detects the magnitude of the output current of the power supply module;

[0097] S1206, determine whether the current detection value is within the range of Imin~Imax;

[0098] S1208, if the judgment result of the above step S1206 is yes, continue to judge whether the difference between the current detection value and the I / V sampling value is greater than Inormal;

[0099] If the judgment result of step S1206 is negative, proceed to step S1212;

[0100] S1210: If the judgment result of step S1208 is negative, the processor processes the voiceprint information normally; otherwise, proceed to step S1212.

[0101] S1212, the processor shuts down the power module output and displays fault information;

[0102] S1214, then determine whether the current is greater than Imax;

[0103] S1216, if the judgment result of the above step S1214 is negative, further determine whether the number of fault timeouts has reached three (other numbers can also be set as needed); if it has not reached three, return to step S1202 to restart the power supply, that is, power on again; if it exceeds three, end directly; or, if the judgment result of the above step S1214 is positive, end directly, that is, when a current greater than Imax occurs, turn off the power supply directly.

[0104] In the above embodiments, it is first explained that when the current exceeds Imax, the power module output is directly shut off; for other fault conditions, there are more than one opportunity to power on and work again, and the power output is shut off after the timeout.

[0105] In an optional embodiment, a timeout mechanism may not be set for other faults, and power may be cut off directly when a fault occurs, such as... Figure 13 As shown, Figure 13 This is a flowchart example of how the processor processes voiceprint data according to an embodiment of the present invention. Figure 2 This process is relative to Figure 12 The process is missing steps S1214-S1216; the other steps are the same as... Figure 12 The same applies here, so I will not repeat it further.

The sampling and intelligent analysis module can be connected to multiple voiceprint acquisition modules, and each channel can independently control the power module output and current monitoring without affecting each other.

[0107] The embodiments of the present invention have the following advantages over related technologies: 1) The voiceprint acquisition module uses only two power supply wires, making installation and wiring simple; 2) It intelligently detects the voiceprint acquisition link and module working status, playing a role in diagnosis and control, making it easy to troubleshoot and maintain, and also providing protection; 3) It uses analog current signal transmission, which has a long transmission distance and is not easily affected by interference; 4) It uses analog signal transmission, which is distortion-free and delay-free; 5) The voiceprint acquisition module has fewer components, greatly reducing the failure rate.
