Technical Field

[0001] The present invention relates to the technical field of signal monitoring, and in particular to a signal monitoring device for a video conference terminal. Background Art

[0002] With the popularity of globalization and remote work, video conferencing technology has become an important tool for corporate communication, team collaboration and cross-regional exchanges. However, with the increasing requirements for conference efficiency and interactivity, the quality of video conferencing upload signals is required to be high. However, in actual applications, due to the influence of various factors, the quality of the uploaded signal often fails to meet expectations, which in turn affects the overall effect of the meeting.

[0003] For example, the impact of network fluctuations: due to network bandwidth limitations, network congestion or network equipment failure, the signal uploaded by the video conferencing terminal may be delayed, stuck or even interrupted, which not only affects the real-time interactive experience of the participants, but may also lead to the loss or misunderstanding of conference information.

[0004] Differences in equipment performance: This will also have a significant impact on the quality of the uploaded signal. Different video conferencing terminals, such as laptops, tablets, and smartphones, have different performances of cameras, microphones, and encoders. Devices with poor performance may experience problems such as blurred images and distorted sounds when processing high-definition video and audio signals, thereby reducing the quality of the uploaded signal.

[0005] Therefore, it is particularly important to propose a device that can monitor and analyze the quality of the video conferencing terminal upload signal in real time. Summary of the invention

[0022] The accompanying drawings are used to provide a further understanding of the embodiments of the present invention and constitute a part of the specification. Together with the following specific implementations, they are used to explain the embodiments of the present invention, but do not constitute a limitation on the embodiments of the present invention. In the accompanying drawings:

[0024] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0025] See also Figure 1 FIG. 1 is a schematic diagram of a signal monitoring device for a video conferencing terminal provided by an embodiment of the present invention, comprising:

[0026] The signal receiving module 10 is used to receive signals uploaded by the video conferencing terminal.

[0027] The signal receiving module includes an antenna device and a signal demodulator, wherein the antenna device is used to receive wireless signals, and the signal demodulator is used to demodulate the received wireless signals into baseband signals.

[0028] In some implementations, the signal uploaded by the video conferencing terminal may be received through three schemes:

[0029] Solution 1: For different networks, the conference video terminal outputs audio and video signals to the conference room video matrix and audio processor to switch to the signal detection device. The conference monitoring personnel remotely log in to the web interface of the signal detection device through the self-built network to view the audio and video effects of the conference room. If you need to view the venue situation, you can access two signals to transmit the venue camera and terminal output screen to the signal detection device respectively.

[0030] Solution 1: The devices involved include: 1 RJ45 network port to realize remote login function. 2 HDMI input signal interfaces and 1 HDMI output signal interface to realize signal access and decoding inside the device, 1 audio input and output interface to realize audio signal input and output functions. 1 power module to provide power for the equipment.

[0031] Solution 2: Configure dual network ports (Lan1 and Lan2) for the same network signal detection device. Lan1 is connected to the switch used by the conference terminal to capture data packets, and Lan2 is connected to the local self-built network to achieve remote monitoring function. The device has built-in audio and video encoding and decoding functions to capture data and decode it.

[0032] The equipment involved in Solution 2 includes: 2 Rj45 network ports, connected to different networks, with built-in network coding chip, the network video data is captured and converted through the first network port, and the venue status can be viewed through the second network port. There is also a power module to provide power for the equipment.

[0033] Solution 3: The equipment is divided into two parts: main and backup. The main equipment is placed in the conference monitoring center, decodes the audio and video signals uploaded by the backup equipment, and outputs them to the monitoring screen or large screen through the HDMI signal of the main equipment. The backup equipment is placed in the conference room, completes the signal acquisition work through the audio and video matrix or captures the audio and video signals of the conference terminal through the switch, uploads them to the main terminal, and can be connected to the conference room camera (with audio acquisition function) to monitor the venue in real time.

[0034] The equipment involved in Solution 3 includes: two sets of equipment, main and sub. The main equipment is responsible for audio and video decoding and outputs the signal to the display device. It is equipped with 8 RJ45 interfaces and 8 HDMI output ports. There is 1 audio input and output port. The sub-device has dual network cards, 1 HDMI input and output interface, and 1 audio input and output interface. The equipment is connected to different networks. The first network port is connected to the conference terminal network. The conference terminal audio and video signals are captured through the conference switch, and uploaded to the main device through the second network port for decoding and output to the display device. Or the conference terminal signal is transmitted to the sub-device through the video matrix through the HDMI input interface of the sub-device, and uploaded to the main device through the second network port.

[0035] The signal analysis module 11 is connected to the signal receiving module and is used to perform real-time analysis on the received signal to obtain signal strength, signal quality and signal stability parameters.

[0036] In some implementations, the signal analysis module is further used to perform denoising and filtering preprocessing on the baseband signal to obtain a preprocessed signal.

[0037] In some implementations, the signal analysis module performs real-time analysis on the received signal to obtain the signal strength, including the following steps:

[0038] S1: Determine the target frequency band according to the frequency band configuration of the video conferencing terminal, and configure a signal analysis module accordingly to capture and analyze signals in the target frequency band simultaneously or sequentially.

[0039] S2: Use filters to isolate the signals in the target frequency band by frequency band, and use RSSI to measure the signal strength in each frequency band.

[0040] S3: Compare the detected signal strength with a preset threshold to determine whether the signal strength meets the preset requirements. If so, recommend a frequency band for video conferencing transmission to the user; if not, provide an optimization strategy for frequency bands with insufficient signal strength or interference.

[0041] It should be understood that the preset requirements can be set according to the actual application scenario and are not limited here.

[0042] Preferably, the optimization strategy may be to adjust the transmission parameters for the frequency band with interference, and to use an enhanced antenna to enhance the signal for signals with insufficient signal strength.

[0043] Specifically, consider the gain and coverage of the signal amplifier to ensure that the amplifier can meet the needs of the required signal enhancement. Install the signal amplifier in a suitable position between the area with insufficient signal strength and the router, and adjust its advanced settings such as gain and output power to maximize the coverage of the signal. After installation and configuration, use a signal detection tool (such as a WiFi analyzer) to measure signal strength and stability to ensure that the signal amplifier is working properly and achieving the expected effect. Place the router closer to the weak signal area to reduce signal attenuation and interference. Make sure the router is placed in a higher position to avoid obstacles blocking the signal. Use a WiFi analysis tool to scan the surrounding wireless signals and find the best wireless channel. According to the router's management interface, adjust settings such as transmit power and wireless frequency band to optimize signal coverage and performance. If the router supports wall penetration mode or similar settings, you can enable it to enhance the signal's penetration ability.

[0044] The output module 12 is connected to the signal analysis module and is used to output signal strength, signal quality and signal stability parameters.

[0045] In some embodiments, the output module includes a display screen and / or a sound output device; wherein the display screen is used to display a graphical interface of the signal analysis results, and the sound output device is used to emit a prompt sound to remind the user of the signal status.

[0046] In some implementations, the signal monitoring device further includes a storage module for storing historical data of signal analysis to facilitate analysis and prediction of signal quality change trends.

[0047] In some embodiments, the signal monitoring device also includes an alarm module, which is used to trigger an alarm signal when the signal analysis results show that the signal quality is lower than a preset threshold, so as to notify the user to take timely action; wherein, the method of triggering the alarm signal includes but is not limited to controlling the indicator light on the display screen to flash, the sound output device to emit an alarm, and sending text messages or emails.

[0048] The technical effects achieved by this application are as follows:

[0049] Through the signal receiving module, the device can capture the signal uploaded by the video conferencing terminal in real time, ensuring the instant perception of the signal status during the conference. The signal analysis module performs real-time analysis on the received signal, allowing the system to quickly and accurately evaluate the signal status. The device can not only obtain the signal strength information, but also analyze the signal quality and stability. The comprehensive acquisition of these parameters provides a rich data basis for subsequent signal optimization and troubleshooting. The design of the output module enables the signal strength, signal quality and signal stability parameters to be presented in an intuitive way, which is convenient for users or administrators to quickly understand the current signal status and make corresponding decisions. Through real-time monitoring and analysis of the signal, the device can issue an early warning in time when there is a problem with the signal, avoiding the interruption or quality degradation of the video conference caused by the signal problem, thereby improving the overall quality of the video conference. Through the analysis of the signal stability parameters, the use of network resources can be further understood, providing a scientific basis for network administrators to optimize resource allocation and improve the utilization rate of network resources. When a video conference fails, by viewing the signal parameters output by the signal monitoring device, the cause of the failure can be quickly located, the troubleshooting time can be shortened, and the troubleshooting efficiency can be improved.

[0050] In summary, the signal monitoring equipment solution for the video conferencing terminal effectively improves the quality and efficiency of video conferencing through real-time, comprehensive and accurate signal monitoring and analysis, and provides strong technical support for network administrators.
