These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0041] First, let me explain the terms used in this application:
[0042] A hardware interface refers to the physical or logical connection point in a computer system used to connect different hardware devices or external devices to the computer body for data transmission and communication. It includes various forms of ports, slots, buses, etc. Through these interfaces, the computer can identify, connect to, and control external devices, enabling data input, output, and interaction between devices.
[0043] A protocol library is a set of pre-written program code or instruction sets used to enable data exchange and communication between different systems, devices, or applications according to specific rules. These protocols define the format, sequence, error detection and correction mechanisms, etc., of data exchange to ensure that information can be transmitted accurately between different entities.
[0044] In the industrial sector, due to technological differences among equipment manufacturers, hardware interfaces and protocols between devices are becoming increasingly diverse. Current technology integrates the hardware interface and corresponding protocol conversion software onto the same development board to achieve protocol conversion and communication between different devices.

If the added data acquisition device is incompatible with the hardware interface of the core board in the existing development board, or if its protocol is not within the scope of the protocol conversion software supported by the core board, the system cannot establish a communication connection with the new device, limiting the system's scalability.

The dynamic protocol library storage device stores and updates protocol libraries not included in the core board. When the core board needs to connect to a new acquisition device, the protocol library required for communication with the new acquisition device can be loaded through the dynamic protocol library storage device, thereby converting the protocol and enabling communication between the core board and the acquisition device, thus improving the scalability of the system.

[0155] exist Figure 6 In the automatic protocol conversion method provided in the embodiment, when the communication connection between the conversion board and the acquisition device is disconnected, the conversion board sends a device offline signal to the core board. Based on the device offline signal, the core board deletes the protocol library corresponding to the first protocol from its memory, and also deletes the first attribute information of the acquisition device and the protocol library corresponding to the first protocol from the conversion board. This ensures that the core board has sufficient memory space for subsequent communication connections, optimizing the resource allocation of the automatic protocol conversion system. Furthermore, by only deleting the protocol library in the core board's memory, when the conversion board re-establishes a communication connection with the acquisition device, the corresponding protocol library can be directly loaded from the core board's hard drive without having to send a request to the dynamic protocol library storage device to obtain the corresponding protocol library. This improves the flexibility and speed of protocol loading in the automatic protocol conversion system.
