Description

Technical Field

[0001] This utility model relates to the field of industrial intelligent voice interaction technology, specifically to an intelligent voice interaction terminal for a station. Background Technology

[0002] With the continuous improvement of industrial automation and informatization, voice interaction technology has been gradually introduced into broadcasting stations, computer rooms, and various unattended sites to assist or replace manual operations, thereby improving operation and maintenance efficiency and management intelligence. However, existing voice interaction terminals are mostly derived from consumer-grade or general-purpose designs, and have many shortcomings in industrial environments.

[0003] On the one hand, industrial sites typically experience significant environmental noise, such as that from fans, air conditioners, and power supply equipment, accompanied by complex electromagnetic interference. These factors significantly impact voice acquisition quality, leading to decreased speech recognition accuracy and consequently affecting system stability and availability. On the other hand, existing voice terminals generally rely on the cloud for speech recognition and semantic analysis. When the network is unstable or interrupted, the terminal struggles to respond promptly to on-site commands and cannot execute critical control operations, posing certain safety risks.

[0004] To address the aforementioned issues, a smart voice interaction terminal is needed that can accurately recognize voice content and enable interaction in industrial environments. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a smart voice interaction terminal for a station, characterized in that it includes a body, an interaction module disposed on the surface of the body, and a main control processing module, an acoustic acquisition module, and a power management module disposed within the body. The acoustic acquisition module includes a dual microphone array, and a sound hole is provided on the surface of the body to allow sound to flow into the internal cavity. The dual microphone array is disposed within the body corresponding to the sound hole.

[0006] The acoustic acquisition module is used for acquiring sound signals, extracting noise, preprocessing sound signals, and enhancing sound signals, and sends the preprocessed sound signals to the main control processing module; it can effectively pick up speech signals in high-noise industrial environments and improve the quality of speech signals through noise reduction, echo suppression and other methods, providing reliable audio input for subsequent speech recognition processing.

[0007] The main control processing module is responsible for scheduling local speech recognition, command parsing, and execution logic.

[0008] The main control processing module includes a speech recognition package responsible for recognizing the collected acoustic information and parsing and executing commands in the speech. This module can recognize and process preset local commands without relying on an external network, and feed the execution results back to the relevant modules, thus ensuring that the terminal can still complete critical control operations in the event of network anomalies or interruptions.

[0009] Furthermore, an isolation structure is provided inside the machine body, which is located between the power management module, the main control processing module, and the acoustic acquisition module.

[0010] The internal structure of the unit is equipped with isolation structures for different functional circuits, which are used to rationally divide and arrange audio circuits, power circuits and communication circuits, thereby reducing electromagnetic coupling and mutual interference between circuits and improving the electromagnetic compatibility performance and operational stability of the whole unit.

[0011] Furthermore, the main control processing module adopts a multi-core processor and has a built-in local keyword recognition engine and TTS speech synthesis module.

[0012] Furthermore, the acoustic acquisition module includes a noise monitoring unit for acquiring noise and an audio front-end processing unit for processing the acquired raw signals.

[0013] By identifying background ambient noise through a noise monitoring unit, the noise reduction effect can be improved and the accuracy of recognizing commands in the sound signal can be enhanced. By adopting a dual-microphone array and speech noise reduction and enhancement processing methods, the speech recognition accuracy in complex noise environments has been improved.

[0014] Furthermore, it also includes a communication module, which includes an Ethernet interface and / or a 4G communication unit located at the rear of the machine body.

[0015] The communication module enables data communication between the terminal and external systems, including the exchange of voice data, command information, and status information with the cloud server. Through the communication module, the terminal can upload voice data to the cloud for semantic analysis and receive control commands or business processing results returned from the cloud, thereby achieving linkage with relevant business systems.

[0016] Furthermore, the interaction module includes buttons and / or display components, which are disposed on the body.

[0017] The display component is used to show the terminal's operating status, network status, and interactive information, and supports necessary human-computer interaction operations. Through the display component, maintenance personnel can intuitively understand the terminal's current working status, improving the convenience and maintainability of on-site use.

[0018] Furthermore, it also includes an environmental sensing module, which includes temperature and humidity sensors.

[0019] Furthermore, the main control processing module also includes a local log management module.

[0020] Beneficial effects

[0021] This invention reduces the problems of high noise and difficult speech recognition in industrial environments by processing local sound. It also combines cloud processing with local processing to achieve dual protection for voice interaction functions. It can utilize cloud computing power to complete complex semantic analysis, and rely on the local recognition mechanism to complete the execution of key commands in the event of network anomalies, significantly improving the stability and reliability of voice control. By adopting a dual-microphone array and voice noise reduction and enhancement processing, the accuracy of speech recognition in complex noise environments is improved. By setting up an internal isolation structure, the impact of electromagnetic interference on system operation is effectively reduced, improving the electromagnetic compatibility performance of the whole machine. At the same time, the terminal adopts an industrial-grade structural design, which can meet the requirements of long-term stable operation in station and unattended scenarios.
