[0001] The utility model relates to the technical field of network accessories, in particular to a serial port adapter supporting multiple bus protocols. Background Art

[0002] With the rapid development of industrial automation, the Internet of Things, and data communication technologies, the demand for interconnection between various types of equipment is becoming increasingly urgent. Serial communication, as a traditional data transmission method, still plays an important role in many fields. However, due to the diversity of serial port protocols used by different devices, such as RS-232, RS-422, RS-485, etc., direct communication between devices becomes complicated and limited. Therefore, it is particularly important to develop a serial port adapter that can support multiple bus protocols. Traditional serial port adapters often only support a single serial port protocol, such as RS-232 or RS-485, and cannot meet the communication needs between multi-protocol devices. This causes users to purchase and install multiple adapters when facing devices with different protocols, which increases costs and complexity. Utility Model Content

Through the serial port adapter shell 10, the detachable top cover 20, the serial port interface 30, the Ethernet interface 40 and the serial port interface circuit, FPGA processor and Ethernet communication module in the internal control panel, support for multiple bus protocols and high-speed and stable network connection are realized, providing users with great convenience and efficient data transmission solutions.

[0027] In this embodiment, the FPGA processor in the internal control panel is used as the core processing unit. With its powerful programmability and high-speed processing capability, it can efficiently process the data from the serial port interface 30 and the Ethernet interface 40, and realize the rapid conversion and transmission of data. This design not only improves the efficiency of data transmission, but also ensures the accuracy and reliability of data transmission.

[0028] Furthermore, heat dissipation vents 11 are symmetrically provided at both ends of the serial port adapter housing 10, and a heat dissipation fan is installed at one set of the heat dissipation vents 11, which effectively improves the heat dissipation performance of the device. The heat dissipation fan can actively accelerate air circulation and quickly discharge the heat generated inside, ensuring that key components such as the FPGA processor, serial port interface circuit and Ethernet communication module can maintain a stable temperature during long-term operation, thereby extending the service life of the product and improving the reliability and stability of the system.

[0029] Among them, fixing ears 12 are installed at the four top corners of the serial port adapter shell 10 on the side away from the removable top cover 20, providing a convenient installation and fixing method for users. The fixing ears are not only sturdy in structure, but also reasonably designed, which is convenient for users to firmly install the adapter in the desired position through screws or other fasteners, thereby enhancing the adaptability and practicality of the product.

[0030] Specifically, the four top corners of the removable top cover 20 are connected to the top of the serial port adapter outer shell 10 through locking bolts 22, which not only ensures the stability of the top cover, but also facilitates the user to disassemble and replace it without destroying the overall structure of the product.

The power module is used to provide stable power for the entire module, receive external power input, and provide the required power voltage for each module after filtering and voltage stabilization. The power module can receive external power input, and after precise filtering and voltage stabilization, provide stable and reliable power voltage for each module.

[0033] The working principle of the serial port adapter supporting multiple bus protocols: a plurality of serial port interfaces 30 installed on one side of the serial port adapter outer shell 10 are bridges for connecting the adapter with external serial port devices (such as sensors, controllers, etc.).

Each serial port interface 30 is closely connected to the serial port interface circuit in the internal control panel to ensure the accuracy and stability of data transmission. The serial port interface circuit located in the internal control panel is the key part for processing serial port signals. It is responsible for decoding, converting and amplifying the original signal from the serial port interface 30 to meet the processing requirements of the FPGA processor. At the same time, the circuit also supports multiple bus protocols to ensure that the adapter can flexibly communicate with different types of serial port devices. FPGA processor: As the core processing unit of the entire adapter, it has a high degree of flexibility and configurability. It can further process, analyze and forward the data from the serial port interface circuit according to the needs of the user and the program settings. The powerful computing power of the FPGA processor ensures the high efficiency and real-time performance of data processing.
