[0034] As Figure 1 shown, the efficient voiceprint recognition tool based on the ERP system of the present application includes a wireless communication module 1, a voiceprint collector 2, a signal amplifier 3, a signal processor 4 and a power module 5. The wireless communication module 1 is used to realize wireless data transmission with the ERP system, which significantly reduces the wiring problem caused by traditional wired connection. The voiceprint collector 2 is used to collect the voice information of the user and convert it into an electrical signal, thereby providing a reliable basic signal for subsequent processing. The signal amplifier 3 is responsible for amplifying the electrical signal output by the voiceprint collector 2 to improve the quality and clarity of the signal. The signal processor 4 then processes the amplified electrical signal, extracts the key voiceprint feature information, and transmits this information to the ERP system through the wireless communication module 1. The power module 5 provides the necessary power for the entire system to ensure that each component can operate stably.

[0035] The wireless communication module 1 is a high-performance wireless communication device that can use Bluetooth, Wi-Fi, or 5G wireless transmission technology. It is usually installed at the top of the voiceprint recognition tool to ensure stable and delay-free data transmission with the ERP system. The voiceprint collector 2 is a high-precision microphone device that can be installed at the front end of the tool, directly facing the user, to collect their voice signals. The signal amplifier 3 is a small electronic amplification circuit installed behind the voiceprint collector 2, closely connected to it to ensure real-time amplification of the signal. The signal processor 4 is an advanced digital signal processor 4 installed below the amplifier, responsible for complex data processing and feature extraction of the received electrical signals. The power module 5 is usually designed in the form of an internal battery, installed at the bottom of the device, providing continuous and stable power supply for all the above components.

[0036] For example, the wireless communication module 1 can use the Wi-Fi chip of the Qualcomm Snapdragon series, supporting high-speed data transmission to ensure real-time and accuracy of data. The voiceprint collector 2 can use MEMS microphones, which have high sensitivity and low noise characteristics, suitable for complex environments. The signal amplifier 3 can use an integrated operational amplifier circuit such as LM358, which adjusts the gain to ensure moderate signal strength and avoid overload or distortion. The signal processor 4 can choose NVIDIA's Jetson nano, a high-performance edge computing platform that can complete complex data processing tasks with low power consumption. The power module 5 can be designed as a lithium battery with an intelligent charge and discharge management system to extend battery life and ensure long-term stable operation of the device.

[0037] The efficient voiceprint recognition tool of the present application solves the problem of difficult wiring in complex and variable working environments through the wireless communication module 1. Specifically, the introduction of the wireless communication module 1 eliminates the limitations of traditional cables on wiring paths, making the installation process more convenient and reducing the risk of failure due to cable damage or interference. In addition, the high reliability and low latency characteristics of the wireless communication module 1 ensure real-time and accuracy of data transmission, further improving the overall performance of the system. Through the above design scheme, the present application not only improves the efficiency of voiceprint recognition, but also significantly reduces the cost of installation and maintenance, especially suitable for working scenarios that require flexible layout and rapid deployment.

[0038] In one embodiment, the wireless communication module 1 in the ERP system-based efficient voiceprint recognition tool of the present application is provided with a pair of antennas 6, which are respectively installed on the two sides of the module. This design ensures that the antennas 6 can receive and send signals in different directions, significantly improving the coverage and strength of the signals. By arranging the antennas 6 on both sides of the module, the module can maintain stable communication performance in complex and variable environments, effectively avoiding the wiring problems caused by wired connections. This layout not only optimizes the efficiency of signal transmission, but also enhances the robustness and reliability of the system, making it more flexible and convenient to use in various environments.

[0039] For example, the wireless communication module 1 includes a pair of antennas 6 and corresponding signal processing units. Each antenna 6 is installed on the two sides of the module housing and connected to the signal processing unit through an internal connector. The signal processing unit is responsible for amplifying, demodulating and encoding the received signals to ensure accurate data transmission. This design allows the antennas 6 to have good coverage in multiple directions, thereby improving the communication performance of the overall system.

[0040] In one embodiment, as shown in Figure 2 The ERP system-based efficient voiceprint recognition tool of the present application includes a wireless communication module 1, which has a signal enhancement chip 7 integrated inside. The signal enhancement chip 7 can effectively enhance signal strength, improve data transmission efficiency, and reduce interference caused by distance and environmental factors on wireless transmission. By achieving optimal signal coupling effect in a limited space, the distance between the signal enhancement chip 7 and the antenna 6 is not more than 10 mm. This design allows them to maintain the shortest distance, thereby improving the coupling efficiency and transmission quality of the signal.

[0041] In addition, a wire 8 (see Figure 3 ) is provided between the signal enhancement chip 7 and the antenna 6, which is made of high-conductivity copper material. Specifically, copper has good electrical conductivity, which can significantly reduce energy loss during signal transmission, further improving the efficiency of data transmission. In order to further prevent interference from external electromagnetic signals, the wire 8 is wrapped with a layer of electromagnetic interference shielding layer 9, which is made of aluminum foil and magnetic material composite, ensuring that the system can still work stably in complex electromagnetic environments, improving the overall reliability.

[0042] For example, the positions for installing the signal enhancement chip 7 and the antenna 6 can be pre-designed on the circuit board of the wireless communication module 1, and the distance between the two is ensured to be no more than 10 mm through precise process. The wire 8 can be directly led out from one end of the signal enhancement chip 7, connected to the input port of the antenna 6, and wrapped with a shielding layer 9 on the entire path to ensure effective isolation of electromagnetic interference. Such layout and material selection make the signal more stable and reliable during transmission.

[0043] In one embodiment, the voiceprint collector 2 of the ERP system-based efficient voiceprint recognition tool of the present application is provided with a directional microphone array 10 comprising multiple miniature microphone units, which can automatically adjust the collection angle according to the direction of the sound source, thereby improving the accuracy and stability of the voiceprint information and avoiding the operational complexity caused by wiring. The multiple miniature microphone units are arranged in a ring structure to form a circular collection area, which can uniformly receive sound signals from different directions to ensure the acquisition of high-quality voiceprint information in complex environments. A sound pickup hole 12 is arranged at the center of the ring structure for collecting sounds within a short distance, and soundproof cotton 13 is arranged around the sound pickup hole 12 to reduce the interference of external noise and improve the clarity of voiceprint collection.

[0044] For example, the miniature microphone units 11 are evenly distributed on the outer edge of the ring structure, and each microphone unit automatically adjusts the collection angle through the built-in direction recognition module and algorithm. This design not only ensures that sound signals from all directions can be effectively captured, but also maintains high-precision voiceprint collection when the sound source moves. The soundproof cotton 13 is installed around the sound pickup hole 12 to effectively shield the interference of external environmental noise and ensure the clarity of near-field sounds.

[0045] In one embodiment, the length of the connection wire 8 between the signal amplifier 3 and the voiceprint collector 2 of the ERP system-based efficient voiceprint recognition tool of the present application is no more than 1 meter. The main purpose of this design is to minimize the attenuation of the signal during transmission, thereby improving the performance and reliability of the entire system. The length limitation of the connection wire 8 ensures the integrity of the signal, avoids interference and noise accumulation caused by long-distance transmission, and further improves the working stability and response speed of the system. The signal amplifier 3 is installed close to the voiceprint collector 2, and the connection between the two is completed through a short and sturdy wire 8, ensuring the shortest and most direct signal transmission path.

[0046] For example, the signal amplifier 3 can be installed next to or below the voiceprint collector 2, with both having high shielding, low impedance materials for the connecting wires, and a length controlled within 1 meter. This not only effectively reduces electromagnetic interference and signal loss, but also simplifies installation and maintenance processes. Through reasonable layout and material selection, the close coupling design between the signal amplifier 3 and the voiceprint collector 2 ensures high fidelity and fast transmission of voiceprint data.

[0047] In one embodiment, the ERP system-based efficient voiceprint recognition tool of the present application has a high-performance DSP chip 14 integrated inside the signal processor 4. This DSP chip has strong computing power and low power consumption characteristics, and can quickly process a large amount of voiceprint signals and convert them into transmissible digital signals. This design significantly reduces the wiring complexity caused by wired connections, thereby improving the integration and reliability of the entire system. The signal processor 4 is located at the core of the entire tool and is connected to the front-end microphone array and the back-end data transmission module through multiple interfaces. This processor not only handles signal processing, but also takes on the task of data management, ensuring the integrity and real-time nature of data during signal transmission.

[0048] The design of the high-performance DSP chip 14 enables the tool to maintain high computing power in complex working environments. For example, the chip can maintain low power consumption when processing a large number of audio signals by using advanced process technology and optimized algorithms, thereby prolonging the working time of the device. In addition, the chip has multiple built-in preprocessing functions such as filtering, noise reduction, and feature extraction, which are completed before the signal enters the processor, further improving the overall processing efficiency. Specifically, the chip uses a multi-core architecture and parallel computing technology to handle different types of audio signal processing tasks.

[0049] In one embodiment, the ERP system-based efficient voiceprint recognition tool of the present application includes a power module 5, which has an intelligent battery management system 15 inside. This intelligent battery management system 15 can monitor and automatically adjust the power supply state of each component in real time, ensuring that the system can still obtain stable power support under different workloads. The power module 5 is usually located at the bottom of the device inside to ensure good heat dissipation performance and easy installation and maintenance. The intelligent battery management system 15 is tightly integrated with the power module 5 and connected to various functional modules such as processors, memories, and input-output interfaces through a set of high-speed data lines.

[0050] The composition of the intelligent battery management system 15 includes a voltage detection unit, a current detection unit, and a temperature monitoring unit, which work together to provide comprehensive power supply monitoring. The voltage detection unit is responsible for monitoring the stability of the input and output voltages to ensure the supply of electrical energy required by each module. The current detection unit is used to monitor the current changes in the circuit to prevent overload situations. The temperature monitoring unit detects the temperature of the power module 5 to prevent damage to system components due to overheating. These units process the monitored information through the built-in data processing module and adjust the power supply strategy of each component according to the preset algorithm, thereby achieving efficient operation and reliable power supply of the system.

[0051] For example, in actual application, when the system workload suddenly increases, the intelligent battery management system 15 will automatically increase the power supply of some key components while reducing the energy consumption of non-critical components, ensuring that the entire system can smoothly cope with high load conditions, thereby effectively preventing system failures caused by unstable power supply. In addition, the system can automatically reduce energy consumption in a long-time low-power state, prolong the battery life, and improve the overall device operation efficiency and stability.

[0052] In actual operation, when the device is in use, first, the user needs to send voice information to the voiceprint collector 2. At this time, the voiceprint collector 2 is responsible for capturing the user's sound waves and converting them into corresponding electrical signals. The generated electrical signals will be transmitted to the signal amplifier 3, which will enhance these weak electrical signals to ensure the integrity and clarity of the information in the subsequent processing process. Next, the enhanced electrical signals will be sent to the signal processor 4, which will perform a series of complex operations on the signals through advanced algorithm technology to extract the voiceprint feature information. These extracted voiceprint features will be re-encoded and sent to the enterprise's ERP system through the wireless communication module 1. This process not only eliminates the wiring trouble brought by traditional wired connection, but also improves the speed and reliability of data transmission. During the entire operation of the device, the power module 5 will continuously provide the necessary power to ensure that the wireless communication module 1, the voiceprint collector 2, the signal amplifier 3, and the signal processor 4 can stably perform their respective tasks. In this way, the efficient voiceprint recognition tool based on the ERP system can greatly improve the performance of the enterprise employees' attendance efficiency, permission verification speed, and other aspects while ensuring information security, providing strong technical support for enterprise management and operation.
