[0056] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0057] Embodiment 1, Figure 1 FIG. 1 is a flow chart showing a first embodiment of a method for converting a communication protocol of the present invention, wherein the method is executed by a conversion module. Figure 1 As shown, the method comprises the following steps:

[0058] Step 110: Receive a conference data signal sent by the PLC end; the conference data signal is sent to the PLC end by one or more conference video devices.

[0059] In some embodiments of the present invention, before receiving the conference data signal sent by the PLC end, the method includes:

[0060] Setting communication parameters with the PLC end; the communication parameters include: one or more of the communication port, baud rate and address;

[0061] Based on the communication parameters, communication is established with the PLC terminal.

[0062] Specifically, the communication between the PLC end and the conversion module is established by configuring the communication parameters to ensure stable data transmission.

[0063] In some embodiments of the present invention, after receiving the conference data signal sent by the PLC end, the method further includes:

[0064] Mark the priority of each conference data signal;

[0065] According to the priority of each conference data signal, the conversion operation is performed on each conference data signal in sequence.

[0066] Preferably, QoS technology (Quality of Service) is integrated in the conversion module. QoS technology can automatically adjust the load distribution strategy to ensure the priority and stability of each conference data signal. QoS technology can reasonably allocate network resources according to the priority and requirements of the conference video system, ensure the fluency of the video conference and the clarity of the audio, and improve the stability and reliability of the system. During the protocol conversion process, QoS technology marks different priorities for data packets of different devices. In this way, when network resources are limited, high-priority data packets (such as key data packets of video conferences) can be processed by conversion operations first, thereby ensuring the quality of video conferences.

[0067] Step 120: converting the communication protocol of the conference data signal.

[0068] The conversion operation includes: parsing and converting the conference data signal according to a preset protocol format to obtain an intermediate data signal; parsing and converting the conference data signal according to a protocol format of a target terminal to obtain a converted data signal.

[0069] In some embodiments of the present invention, the conference data signal is parsed and converted according to a preset protocol format to obtain an intermediate data signal, including:

[0070] Parsing a preset field, an identifier or a feature code of a data frame of the conference data signal to obtain a communication protocol type of a conference video device corresponding to the conference data signal;

[0071] Determine the corresponding preset protocol format according to the communication protocol type;

[0072] According to the preset protocol format, the conference data signal is converted into an intermediate data signal in the preset protocol format.

[0073] In some embodiments of the present invention, converting the conference data signal into an intermediate data signal in a preset protocol format according to the preset protocol format includes:

[0074] Extracting a first preset parameter of the conference data signal, filling the first preset parameter into a data structure of a preset protocol format, and obtaining an intermediate data signal of a preset protocol format;

[0075] The first preset parameters include: one or more of device ID, data type, function code and data content.

[0076] Specifically, the conversion module parses the specific fields, identifiers or feature codes of the data frames of the conference data signal to identify the protocol type of the conference video device, such as HDMI protocol, H.264 protocol or SIP protocol. The conversion module applies the preset conversion rules according to the identified protocol type to convert the device signal into a unified intermediate protocol format. The conversion operation also includes: data decoding, encoding, verification and formatting operations to ensure the consistency and readability of the data in the conference system.

[0077] The intermediate protocol format is customized, and the intermediate protocol data structure is unified and does not depend on a specific source or target protocol.

[0078] When new devices or protocols are added, adjust the data acquisition program on the PLC side and configure new communication parameters, such as baud rate, data bits, and stop bits. Modify the preprocessing algorithm on the PLC side to perform a new format check on the received data to ensure the correctness of the new data format.

[0079] Add new protocol recognition logic in the conversion module, write new conversion rules, including data decoding, encoding, verification and formatting operations, and adjust the intermediate protocol format. Without large-scale reprogramming of the PLC, new protocols can be supported by adding or modifying the intermediate protocol format.

[0080] In some embodiments of the present invention, parsing and converting the conference data signal according to the protocol format of the target terminal to obtain the converted data signal includes:

[0081] parsing and converting the second preset parameter of the intermediate data signal according to the protocol format of the target terminal to obtain a converted data signal;

[0082] The second preset parameters include: one or more of device ID, device type, function description byte, data length and data content.

[0083] For example, taking RS-232 and USB as two communication protocols, a custom data structure is created to store basic information of the device and the data transmission format. This usually includes the device ID, device type identifier, function description byte and other necessary fields.

[0084] Receive first data from the RS-232 port, parse a first data frame under the RS-232 protocol and identify a specific command sequence as a device function identifier, fill it into a data structure of a custom intermediate protocol for encapsulation, and obtain first intermediate data.

[0085] For the second data received from the USB port, the corresponding fields of the second data frame under the USB protocol are parsed and filled into the data structure of the custom intermediate protocol for encapsulation to obtain the second intermediate data.

[0086] The data of the two protocols are converted into the same intermediate format for subsequent unified processing, such as network transmission or data analysis. For example, if the first intermediate data needs to be transmitted to a device supporting the USB protocol, the first intermediate data is converted and adjusted according to the requirements of the USB protocol and then sent to the USB port of the device.

[0087] Preferably, error handling and debugging are performed on the conversion module to ensure that the module can properly handle possible protocol anomalies, data loss or other error situations, and provide effective log and debugging information.

[0088] Step 130: Send the conversion data signal to the PLC end, so that the PLC end sends the conversion data signal to the target terminal.

[0089] In some embodiments of the present invention, before sending the converted data signal to the PLC end, the method further includes:

[0090] determining at least one routing path between the conversion module and the target terminal;

[0091] If there are at least two routing paths between the conversion module and the target terminal, determining an optimal routing path according to the network transmission parameters and the preset strategy of each of the routing paths;

[0092] The converted data signal is sent to the PLC end by using the optimal routing path, so that the PLC end sends the converted data signal to the target terminal.

[0093] Specifically, an intelligent routing algorithm is integrated in the conversion module. The intelligent routing algorithm can dynamically select the optimal routing path according to the network status to ensure the efficiency of data transmission. The conversion module monitors the network status in real time, such as bandwidth, delay, packet loss rate, etc. Based on the real-time monitoring data, it calculates all possible routing paths and selects the optimal path according to preset strategies, such as the shortest path, the least delay and the highest reliability, to reduce the delay and congestion of data transmission. When congestion or failure is detected in a routing path, the algorithm can quickly switch to an alternative path to ensure the continuity and stability of data transmission.

[0094] The present invention can automatically identify and efficiently convert the protocols of different video conferencing devices, ensuring that data is unimpeded in a complex network environment, and that video conferencing has smoother audio and video transmission and lower latency. By converting to a unified intermediate protocol format, the system can standardize the processing of data from different sources, improve the consistency and manageability of data, and ensure seamless collaboration and compatibility between different devices. PLC, as the core of data acquisition and control, combined with the efficient processing capabilities of C language, enables the system to process large amounts of data and maintain stable operation under high-load environments. The present invention separates the protocol conversion function from PLC and uses C language to write independent modules, which can make system maintenance and upgrades easier and reduce maintenance costs. The system can dynamically adjust the data transmission path and load distribution strategy according to the network conditions, ensure the priority and stability of key applications, and help maintain the continuity and quality of audio and video transmission when the network is congested.

[0095] Embodiment 2, Figure 2 FIG. 2 is a flow chart showing a second embodiment of a method for converting a communication protocol of the present invention, which is executed by a PLC terminal. Figure 2 As shown, the method comprises the following steps:

[0096] Step 210: receiving conference data signals sent by one or more conference video devices;

[0097] Step 220: Sending the conference data signal to a conversion module, so that the conversion module processes the conference data signal using the communication protocol conversion method described in Example 1;

[0098] Step 230: Receive the converted data signal sent by the conversion module, and send the converted data signal to the target terminal.

[0099] In some embodiments of the present invention, before sending the conference data signal to the conversion module, the method further includes:

[0100] Preprocessing the conference data signal;

[0101] The preprocessing includes: one or more of signal amplification, signal filtering and signal format verification.

[0102] In some embodiments of the present invention, a programming language supported by the PLC, such as ladder diagram and structured text, is used on the PLC side to write programs for data collection, preprocessing, sending and receiving.

[0103] Among them, the data acquisition program is written using ladder diagrams and is implemented by configuring input modules and reading the status of input signals.

[0104] Data preprocessing involves the use of structured text, by writing algorithms to amplify, filter, and format-check the collected data.

[0105] The data sending and receiving program needs to configure the communication parameters of the PLC and write the corresponding program to realize the sending and receiving of data. Ladder diagrams are suitable for intuitive logic control, while structured text is suitable for complex calculations and algorithm implementation. Configure the communication parameters of the PLC to ensure a stable connection with the host computer or embedded system. Set the communication port, baud rate, address and other parameters of the PLC, and perform correct communication configuration with the protocol conversion module to ensure stable data transmission.
