Description

Technical Field

[0001] This utility model relates to the field of monitoring technology, and in particular to an audio detection and early warning module, a multi-person review monitoring system and device. Background Technology

[0002] Currently, the selection of suppliers as successful bidders in public procurement bidding mainly adopts manual review. Although the review process uses video monitoring to preserve audio and video data, which can be used as evidence for later tracing, it is impossible to provide timely risk warnings and alerts during the review process. In the later tracing process, it is difficult and time-consuming to identify personal biases and opinions in the review and discussion. Moreover, by the time opinions that affect the fairness and impartiality of the procurement are discovered, it is relatively late, affecting the timeliness of the procurement activities.

[0037] Please see Figure 1-2 An audio detection and early warning module 6 provided in this embodiment of the present invention includes a voice collection component 2, an alert component 3, a shutdown component 5, and a processing component 4;

[0038] Processing component 4 includes a voice recognition unit, voice collection component 2 and warning component 3 are both connected to the voice recognition unit, and shutdown component 5 is connected to warning component 3;

[0039] The voice collection component 2 is used to collect sound data and transmit it to the voice recognition unit. The voice recognition unit is used to identify sensitive words in the sound data and output warning signals to the warning component 3 to start the warning. The shutdown component 5 is used to control the warning component 3 to stop the warning.

[0040] Understandably, in specific implementation, voice data is collected through voice collection component 2, and the voice recognition unit receives and recognizes the voice data to determine whether there are sensitive words. If there are sensitive words, an alarm signal is output to the alarm component 3 to activate the alarm. The alarm component 3 is used to remind the reviewers, so as to realize timely risk reminders and warnings during the review process, which helps to reduce the occurrence of violations. At the same time, by closing component 5, the alarm component 3 stops the alarm, and the review process can be quickly resumed after the alarm is triggered.

[0041] It should be noted that the voice recognition unit's function of identifying sensitive words in sound data and outputting warning signals to warning component 3 is existing technology. For details, please refer to publication number CN213305581U. The existing technology discloses an intelligent video surveillance system based on voice recognition that includes a voice processing and recognition module. This module can process and recognize the collected voice information. When sensitive words are identified, it will trigger an alarm through relevant modules. The alarm module drives the alarm indication module to achieve active alarm. This is consistent with the implementation principle of the voice recognition unit in this solution identifying sensitive words in sound data and outputting warning signals to the warning component. The only difference between this solution and the existing technology is the application scenario. The voice recognition unit in this solution is used for procurement review, while the existing technology is used for monitoring needs in public places.

[0042] In a more specific embodiment, the voice recognition unit outputs a warning signal to the warning component 3 to activate the warning, and the shut-off component 5 controls the warning component 3 to stop activating the warning. This can be achieved by the following implementation: the warning component 3 is connected in series with switches S1 and S2. Switch S1 is connected to the voice recognition unit. Switch S1 is normally open and closes when the voice recognition unit issues a warning signal, energizing the warning component 3 to activate the warning. Switch S2 is connected to the shut-off component 5. Switch S2 is normally closed and opens when the shut-off component 5 is operated, de-energizing the warning component 3 and stopping the warning.

[0043] In a more specific embodiment, such as Figure 2As shown, the warning component 3 includes an audible warning device 32 and a visual warning device 31. The visual warning device 31 includes a multi-color LED light module 312. The processing component 4 also includes a warning classification processing unit. The input end of the warning classification processing unit is connected to the output end of the voice recognition unit, and the output end of the warning classification processing unit is connected to the visual warning device 31. The warning classification processing unit is used to output different levels of warning signals according to the sensitive word situation to control the visual warning device 31 to light up different colors.

[0044] Understandably, in practical implementation, on the one hand, light warnings rely on visual signals, suitable for scenarios where lighting conditions permit and personnel are within sight (such as close observation or quiet environments), and can convey accurate information through color and flashing frequency. On the other hand, sound warnings rely on auditory signals, are not limited by sight, and can be promptly alerted through tone, loudness, and rhythm even if personnel have their backs to the equipment or are overly focused on the review. Combining the two can cover the "blind spots" that may exist in visual or auditory channels alone, ensuring that warning signals can be effectively received in different environments (such as noisy / quiet) and personnel states. By using the colors displayed by the multi-color LED light module 312 (such as red for severe, yellow for moderate, and blue for mild), the severity of sensitive words is directly mapped. Compared to text or sound prompts, visual signals are received faster, allowing reviewers and on-site staff to quickly determine the level of the problem without interpreting complex information. This design transforms the abstract concept of "sensitivity" into a concrete visual signal through color, which not only improves the efficiency and accuracy of information transmission, but also provides clear guidance for staff on whether to intervene in the review process (e.g., red warnings may require immediate intervention, while other lighter colors can be postponed). It is especially suitable for review scenarios that require fast response and accurate judgment.

[0045] In a more specific embodiment, the implementation scheme for the warning classification processing unit to output different level warning signals to control the light warning device 31 to light up different colors according to the sensitive word situation is as follows: When the light warning device 31 is powered on and the warning is activated, since the warning classification processing unit is connected to the light warning device 31, and the light warning device 31 is equipped with a multi-color LED light module 312, the warning classification processing unit can output different level warning signals, which can be PWM control signals with different duty cycles (or drive signals with different current distribution ratios). The multi-color LED light module can display different colors according to the brightness ratio instructions of the red, green, and blue (or other basic color) chips in these signals. For example, when the severe warning signal is activated, the signal "red light chip duty cycle 100%, green / blue light chip 0%" is output, and the module displays pure red; when the level 2 warning (minor warning signal) is activated, the signal "red light duty cycle 50%, green light duty cycle 50%" is output, and the module displays orange; when the level 3 warning (minor warning signal) is activated, the signal "green light chip duty cycle 100%" is output, and the module displays pure green.

[0046] It should be noted that the early warning and grading processing unit, which outputs different levels of warning signals based on sensitive words, is existing technology. For details, please refer to publication number CN216795178U. This existing technology discloses an intercom device including an early warning and grading unit, which is connected to a voice recognition unit and determines the corresponding sensitivity level based on the comparison information obtained from the voice recognition unit. The implementation principle of the early warning and grading processing unit in this solution, which outputs different levels of warning signals based on sensitive words, is the same. The difference between this solution and the existing technology lies in their application scenarios. The voice recognition unit in this solution is used in procurement reviews, while the existing technology is used in bank counter intercoms.

[0047] In a more specific embodiment, a fingerprint recognition component 15 is also included. The fingerprint recognition component 15 is connected to the warning component 3. The warning signals include a minor warning signal and a severe warning signal. When the light warning device 31 receives a severe warning signal, the fingerprint recognition component 15 is used to control the warning component 3 to stop the warning only when the fingerprint recognition component 15 recognizes the fingerprint of the staff member.

[0048] Understandably, in practice, this is achieved through the integration of the fingerprint recognition component 15: when the light warning device 31 receives a severe warning signal, it illuminates a color light corresponding to the severity of the sensitivity, alerting the staff. Once the staff confirms that the review process can continue, they perform fingerprint recognition and then press the light warning device 31 to stop the warning, effectively strengthening the control of the review process. Severely sensitive words typically involve high-risk content (such as violations, major errors, etc.) and must be handled by staff with appropriate permissions (such as senior reviewers or supervisors). Fingerprint recognition is performed when the staff confirms that the review process can continue, and the light warning device 31 is pressed to stop the warning, effectively strengthening the control of the review process. If serious problems arise in the review process due to sensitive words, they can be resolved promptly. As a biometric method, fingerprint recognition can accurately restrict operational permissions, preventing unauthorized or low-authority personnel from arbitrarily stopping the warning and ensuring that serious issues are handled in a standardized manner.

[0049] In a more specific embodiment, the fingerprint recognition component 15 is used to ensure that the warning component 3 stops issuing warnings only when the fingerprint recognition component 15 recognizes the employee's fingerprint when the light warning device 31 receives a severe warning signal. This can be achieved by:

[0050] The light warning device 31 is connected in series with switches S1 and S2. The voice recognition unit is connected to switch S1 and is normally open. The switch assembly is connected to S2 and is normally closed. The fingerprint recognition assembly 15 is connected to S3. S3 and S2 are connected in parallel. When the light warning device 31 receives a serious warning signal, S3 is normally closed. When the fingerprint recognition assembly 15 recognizes a specific fingerprint, switch S3 is open. When the light warning device 31 receives a minor warning signal, S3 is normally open.

[0051] This embodiment also provides a multi-person review monitoring system, such as Figure 7 As shown, there are multiple audio detection and warning modules 6 and a console 7. The processing components 4 of the multiple audio detection and warning modules 6 are all connected to the console 7, which is used to store the information data generated by the processing components 4.

[0052] Understandably, in specific implementation, the processing components 4 of multiple audio detection and early warning modules 6 are connected to the console 7. The console 7 is used to store the information data generated by the processing components 4, which can realize the centralized aggregation and unified management of information, avoid the chaos and redundancy caused by the scattered storage of data, and make the console 7 the information hub. The console 7 stores the information data generated by each processing component 4, which provides convenience for subsequent traceability and query.

[0053] In a more specific embodiment, the voice collection component 2 is connected to the voiceprint recording switch 9, and the processing component 4 includes a voiceprint feature extraction unit. The voice collection component 2 is connected to the voiceprint feature extraction unit, and the voiceprint feature extraction unit is connected to the console 7.

[0054] The voiceprint recording switch 9 is used to enable the voice collection component 2 to collect the voice signal of the personnel before the review and send the voice signal to the voiceprint feature extraction unit. The voiceprint feature extraction unit is used to output the voiceprint feature signal to the console 7 according to the voice signal. The voiceprint feature signal is used to compare with the audio containing sensitive words output by the speech recognition unit to obtain the audio detection and early warning module 6 corresponding to the audio containing the sensitive word.

[0055] Understandably, before the review, the voice collection component 2 is triggered to start recording by the voiceprint recording switch 9. The sound signal collected by the voice collection component 2 is sent to the voiceprint feature extraction unit for voiceprint feature signal extraction and stored in the console 7. When the console 7 receives audio containing sensitive words from the voice recognition unit, it compares the audio containing sensitive words with the voiceprint feature signal to know which audio detection and warning module 6 issued the audio containing sensitive words.

[0056] In a more specific embodiment, the voiceprint feature extraction unit uses the iFlytek offline voiceprint Android SDK. Following its documentation, the project is imported, the corresponding voiceprint information registration interface is called, and audio data that meets the requirements (such as 16k, 16bit, single channel, PCM audio) is input to extract the voiceprint for subsequent processing.

[0057] In a more specific embodiment, a display screen 8 is also included, which is connected to a console 7, which is used to display sensitive words and the identity information of the reviewers;

[0058] The processing component 4 includes a face recognition unit, and the multiple audio detection and early warning modules 6 include a camera component 10. The camera component 10 is connected to the face recognition unit. The camera component 10 is used to acquire the facial image of the reviewer and send it to the face recognition unit. The face recognition unit outputs the reviewer's identity information to the console 7 based on the facial image. The console 7 is used to store the reviewer's identity information and voiceprint feature signal corresponding to the same audio detection and early warning module 6.

[0059] Understandably, in specific implementation, one seat 14 corresponds to one audio detection and early warning module 6, and the seats of the reviewers are random. Before the review, the camera component 10 takes a picture of the reviewer's face and sends it to the face recognition unit. The face recognition unit has stored the identity information of the reviewer's face image set in advance. By comparing the captured face image of the reviewer with the pre-stored face image, the identity information of the captured reviewer is obtained. The console 7 simultaneously obtains the voiceprint feature information of the audio detection and early warning module 6 and the identity information of the reviewer. When the console 7 receives audio containing sensitive words from the speech recognition unit, it compares the audio containing sensitive words with the voiceprint feature signal to know which audio detection and early warning module 6 issued the audio containing sensitive words and which reviewer issued it.

[0060] Furthermore, the multi-audio detection and early warning module 6 connects to a conference console 7 and displays the expert's identity and the sensitive words on the display screen 8. This real-time display of sensitive words and their corresponding expert identities allows reviewers, moderators, and others at the conference to quickly pinpoint the source of the problem (which expert mentioned the sensitive word) and the specific content (what the sensitive word is), without repeatedly reviewing the audio or relying on memory, reducing information delays and errors. Publicly displaying the expert's identity corresponding to the sensitive word directly constrains the speaker—clearly identifying "whose speech caused the problem," prompting experts to be more cautious in avoiding sensitive content and reducing the risks of careless expression or negligence. The conference console 7 is typically operated by the moderator or on-site management personnel, and the real-time information on the display screen 8 provides them with precise control information: based on the severity of the sensitive word and the personnel involved, they can quickly decide whether to interrupt the speech, issue a reminder for correction, or communicate individually during breaks in the conference, avoiding mismanagement due to unclear information (such as wrongly blaming others or overlooking problems).

[0061] It should be noted that the method of recording the identity information and voiceprint information of the reviewers before the review is stored in console 7, and used to determine which reviewer the sensitive words came from, is existing technology. Specifically, refer to publication number CN 118714368A. In existing security processing systems, the content review auxiliary system pre-obtains the correspondence between each participant user and their voiceprint features based on the multi-channel uplink audio streams of multiple participants in the target session. After the content security review system identifies the illegal content in the mixed audio stream, the auxiliary system extracts the target audio segment containing the illegal content and matches it with the voiceprint features of each participant user to locate the target participant user corresponding to the illegal content. This solution can apply the method for locating target participants based on the illegal content disclosed in existing technology to console 7. Console 7 obtains the audio containing sensitive words from the speech recognition unit of the audio detection and warning module 6. According to existing technology, the audio containing sensitive words is matched with the stored voiceprint information to achieve the matching of sensitive word audio with reviewer information.

[0062] This embodiment provides an integrated device for audio detection and early warning in procurement activity reviews, such as... Figures 3-7 As shown, the audio detection and warning module 6, including any of the above embodiments, includes an integrated box 1, a voice collection component 2, an alert component 3, and a shutdown component 5 disposed on the surface of the integrated box 1, and a processing component 4 disposed inside the integrated box 1.

[0063] The warning component 3 includes a light warning device 31, which is disposed on the surface of the integrated box 1. The closing component 5 includes a first groove 51, a first protrusion 52, and a first elastic member 53 disposed on the opening of the integrated box 1. The first protrusion 52 is disposed in the middle of the first groove 51, located below the bottom of the light warning device 31. One end of the first elastic member 53 is connected to the bottom of the light warning device 31, and the other end is connected to the bottom of the first groove 51. The first elastic member 53 is used to support the light warning device 31 to disengage from the first protrusion 52. The first protrusion 52 is used to stop the warning component 3 from warning when it contacts the bottom of the pressed warning component 3.

[0064] Understandably, in specific implementations, by placing the light warning device 31 on the surface of the integrated box 1 and by setting the first groove 51, the first protrusion 52, and the first elastic element 53, the light warning device 31 and the switch assembly are integrated. When the light warning device 31 is pressed, the spring is compressed, and the bottom of the light warning device 31 contacts the first protrusion 52, triggering the warning assembly 3 to stop the warning. This implementation integrates the closing assembly 5 with the light warning device 31, eliminating the need for separate closing devices (such as separate buttons or switches) on the surface of the integrated box 1, reducing the number of parts and making the overall structure more compact. The action of pressing the light warning device 31 simultaneously achieves the functions of spring compression and triggering the warning assembly 3 to stop, making the operation logic more intuitive, and users do not need to learn complicated closing methods. The integrated design makes the operation points more concentrated, allowing for faster closing operations and improving efficiency.

[0065] In a more specific embodiment, the first elastic element 53 is a spring.

[0066] In a more specific embodiment, the light warning device 31 includes a transparent lampshade 311 and a multi-color LED light module 312, the multi-color LED light module 312 being disposed inside the transparent lampshade 311, the transparent lampshade 311 being an arc-shaped structure.

[0067] In the implementation, when the light warning device 31 receives a warning signal, the multi-color LED light module 312 is illuminated, alerting and warning the reviewer. The reviewer then directly presses the transparent lampshade 311, turning off the multi-color LED light module 312. The transparent lampshade 311 supports the hand pressing operation while protecting the multi-color LED light module 312, and also serves as a carrier for transmitting the warning light, ensuring the normal transmission of the multi-color LED light module 312. This helps the reviewer to directly locate the operation point (the transparent lampshade 311 is the carrier of the warning light source) visually when they see the warning from the multi-color LED light module 312, without needing to find a button. The pressing action is directly related to the logic of "turning off the warning," requiring no learning cost and omitting the intermediate steps of "finding a button → pressing." Especially in review scenarios requiring rapid response, this can shorten operation time and improve efficiency. By setting the transparent lampshade 311 into an arc-shaped structure, the comfort of pressing the hand is improved. The arc-shaped transparent lampshade 311 conforms to the natural curvature of the hand when pressing, which can distribute the pressing pressure, reduce the discomfort caused by excessive local pressure on the hand, reduce the "operational deviation" during pressing (such as uneven force caused by the displacement of the pressing position), and ensure that the extinguishing function can be stably triggered every time it is pressed.

[0068] In a more specific embodiment, the scheme for stopping the warning component 3 from issuing a warning when the first protrusion 52 contacts the bottom of the pressed warning component 3 is as follows: the warning component 3 is connected in series with switches S1 and S2. Switch S1 is connected to the voice recognition unit. Switch S1 is normally open and closes when the voice recognition unit issues a warning signal, energizing the warning component 3 and activating the warning. Switch S2 is connected to the closing component 5. Switch S2 is normally closed and opens when the closing component 5 is operated, de-energizing the warning component 3 and stopping the warning. When the first protrusion 52 contacts the bottom of the warning component 3, the closing component 5 is operated, and switch S2 changes from being normally closed to being open, de-energizing the warning component 3 and stopping the warning.

[0069] In a more specific embodiment, the fingerprint recognition component 15 is disposed on the surface of the light warning device 31. It is understood that, in practice, when the fingerprint recognition of the staff is successful, the staff can press the light warning device 31 to cancel the operation of the warning component 3 without removing their hand, thereby improving the efficiency of operation.

[0070] In a more specific embodiment, the voice collection component 2 is disposed on the surface of the integrated box 1 and is connected to the voiceprint recording switch 9. The voiceprint recording switch 9 includes a second groove 91, a second protrusion 92 and a second elastic member 93 disposed on the integrated box 1. The second protrusion 92 is disposed in the middle of the second groove 91. One end of the second elastic member 93 is connected to the bottom of the voice collection component 2 and the other end is connected to the bottom of the second groove 91. The second elastic member 93 is used to support the voice collection component 2 to disengage from the second protrusion 92.

[0071] The second protrusion 92 is used to connect with the bottom of the pressed voice collection component 2 to enable the voice collection component 2 to collect the voice signal of the personnel before the review and transmit the voice signal to the voiceprint feature extraction unit.

[0072] In practice, the voice collection component 2 stops recording before the review. When the voice collection component 2 is pressed, the second elastic element 93 springs and compresses, causing the bottom of the voice collection component 2 to contact the second protrusion 92, triggering the voice collection component 2 to start recording. This implementation integrates the voiceprint recording switch 9 with the voice collection component 2, eliminating the need for a separate voiceprint recording switch 9 (such as a separate button or switch) on the surface of the integrated box 1, reducing the number of parts and making the overall structure more compact. The action of pressing the voice collection component 2 simultaneously achieves the functions of compressing the elastic element and triggering the voice collection component 2 to record. The operation logic of recording only occurs when the voice collection component 2 is pressed is more intuitive, and users do not need to learn complicated shutdown methods. The integrated design makes the operation points more concentrated, allowing for faster shutdown operations and improving efficiency. In this embodiment, the voiceprint of the reviewer is recorded to the control panel 7 before the review, facilitating comparison with subsequent sensitive word audio to determine which reviewer the sensitive word originated from.

[0073] In a more specific embodiment, the second elastic element 93 is a spring.

[0074] In a more specific embodiment, the voice collection component 2 is a microphone.

[0075] In a more specific embodiment, the camera assembly 10 is rotatably connected to the surface of the integration box 1 via a flexible tube 11.

[0076] Understandably, in practice, the camera assembly 10 is rotatably connected to the surface of the integrated box 1 via the flexible hose 11, allowing the angle of the camera assembly 10 to be adjusted at will, facilitating the reviewers' shooting operations.

[0077] In a more specific embodiment, the hose 11 is a hollow hose that can be freely deformed.

[0078] In a more specific embodiment, one end of the hose 11 is connected to the camera assembly 10, and the other end of the hose 11 is connected to the surface of the integrated box 1 via the turntable 12.

[0079] In a more specific embodiment, a power supply component 13 is also included. The power supply component 13 is disposed in the integrated box 1 and detachably connected to the integrated box 1. The power supply component 13 is connected to the voice collection component 2, the processing component 4, the alarm component 3, the shutdown component 5, the voiceprint recording switch 9, and the camera component 10.

[0080] The power supply component 13 of the audio detection and early warning module 6 used for procurement activity review adopts a detachable design. It can flexibly cope with the situation of variable review activity duration and different site power supply conditions. By quickly replacing the backup power supply, it can ensure the continuous operation of the equipment during long review or sudden power outages, avoiding interruption of sensitive word detection. At the same time, it is easy to maintain or replace easily worn power supply components, reducing maintenance costs and time. It can also adapt to multiple power supply modes such as mains power and power supply component 13, reducing the transportation and storage volume, and even supporting future power upgrades, which greatly improves the practicality, stability and life cycle of the equipment in procurement review scenarios.

[0081] In a more specific embodiment, the sound alarm 32, processing component 4, and power supply component 13 are all housed within the integrated box 1. The power supply component 13 is positioned below the voice collection component 2, improving the space utilization of the integrated box 1. Only the camera component 10, voice collection component 2, and light alarm 31 are visible on the surface of the integrated box 1; all other components are housed within the integrated box 1. This design not only improves the space utilization of the integrated box 1 by placing the power supply component 13 below the voice collection component 2, but also significantly reduces the area occupied by the integrated box 1 by only having the camera component 10, voice collection component 2, and light alarm 31 on the surface, while concealing the remaining components. This approach emphasizes core functions, reduces interference, and makes the device more practical and convenient during procurement review activities, allowing it to flexibly adapt to the spatial environment of the review site.

[0082] In summary, the audio detection and early warning module 6 and the multi-person review monitoring system and device provided by this utility model can quickly identify personnel or statements that may affect the impartiality of procurement through real-time alerts and warnings, promptly reminding relevant personnel to correct any deviations, increasing the transparency of the procurement process, making the review stage more open, and preventing violations. This improves the efficiency of the entire procurement review process. Simultaneously, for procurement regulatory agencies, it allows for dynamic monitoring of the entire procurement review process and automatically forms a chain of evidence, greatly reducing the difficulty of on-site supervision and subsequent traceability.
