[0029] It should be noted that:

[0030] Interface design

[0031] External interface: ICCOM software exchanges information with users through the operating system kernel support software, providing a variety of external interfaces, such as socket, connect, send, recv and other interfaces for Socket communication; open, write, read and other interfaces for TTY communication; and a series of interfaces for redundancy modules and diagnostic modules to facilitate user configuration and operation of the system.

[0032] Internal interface: Each module exchanges data and calls functions through internal interfaces. For example, the iccom_init and iccom_start interfaces in the ICCOM core module are used for device initialization and startup, and the iccom_diagnostic_init and iccom_diagnostic_exit interfaces in the diagnostic module are used for initialization and shutdown of the diagnostic system.

[0033] Data processing and management: Strictly verify the format and content of input and output data, using methods such as format checks and data CRC checks to ensure data correctness. Define various data structures and their value ranges, and perform value range checks during program execution to ensure data validity.

[0034] Security and reliability design: For security, we conduct boundary checks to ensure data compliance and log key operations for easy tracking and auditing. For reliability, we adopt a modular design approach to reduce coupling between modules, increase code commenting and enhance code readability, provide a multi-level logging system to facilitate rapid problem identification, and use the Git version control system to manage code for easy rollbacks and fixes.

[0035] Example

[0036] Installation and Deployment

[0037] Install the ICCOM software system on the target embedded device, ensure that the device meets the hardware and software requirements for system operation, and configure various system parameters such as communication interface type, network settings, and redundant computing strategy according to the actual application scenario.

[0038] Hardware Connection

[0039] According to the selected communication interface (such as TTY, Socket, etc.), correctly establish the hardware connection between the devices. For example, for a TTY interface, connect a serial cable; for a Socket interface, ensure that the devices are on the same network.

[0040] Start the system

[0041] Start the ICCOM software system, and the system will automatically perform operations such as device initialization, driver loading, and network configuration.

[0042] Message creation and sending

[0043] On the sending end, the upper-layer application creates a message object through the API interface provided by ICCOM and specifies the message's destination, priority and other parameters. After receiving the message, the ICCOM core module selects the appropriate communication interface and routing path for transmission based on the message's destination and priority. If the redundant calculation module is enabled, the system will perform redundant encoding on the message to improve the reliability of data transmission.

[0044] Message reception and processing

[0045] At the receiving end, the ICCOM underlying communication module receives messages through the corresponding communication interface. The system decodes and verifies the received messages to ensure the integrity and correctness of the messages. If the message passes the verification, the ICCOM core module passes the message to the upper-level application for processing; otherwise, the system will discard the message and record an error message.

[0046] In addition, during system operation, the diagnostic system module monitors the system status and performance data in real time. If an anomaly or potential problem is found, the system will trigger the fault diagnosis mechanism to locate and analyze the problem. Based on the diagnostic results, the system can automatically perform recovery operations or notify the user for manual intervention. The ICCOM software system provides a detailed logging function that records key operations and error information during system operation. Users can view log information at any time through the log viewing tool provided by the system to facilitate problem troubleshooting and system maintenance.

[0047] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as illustrative and non-restrictive in all respects. The scope of the present invention is defined by the appended claims rather than the foregoing description, and all changes that come within the meaning and range of equivalents of the claims are intended to be included therein.
