The core of the IoT system lies in the interconnection between its components, which relies on stable and reliable communication protocols.

[0003] In the IoT system, the communication protocol between various components is the key to ensure accurate and timely data transmission. The communication protocol defines the format, rate, error detection and correction methods of data transmission, etc. Due to the diversity and complexity of IoT systems, there are multiple communication protocols. Existing communication protocol testing methods usually rely on specific software or hardware tools, which often only support a limited number of communication protocols. This results in the need to use multiple different test tools when testing multiple communication protocols, which increases the complexity and cost of testing. In the traditional communication protocol testing process, there are many and complex communication protocols, large workload, high cost, and difficult to ensure data reliability. In addition, existing testing methods may lack flexibility and are difficult to adapt to changing testing needs.

9. The Python-based communication protocol integrated test system according to any one of claims 5-8, characterized in that: The working process of this system testing a Modbus TCP communication protocol is as follows: The first step is to start the test software, open the communication protocol integrated test software written in Python, and operate it through the GUI interface built by the Tkinter library; Step 2: Select "Modbus TCP" as the communication protocol for the test in the protocol selection interface, and click the "Start Client" or "Start Server" button; The third step is client configuration, as follows: ①Server communication address configuration: Enter the server IP address as "192.168.1.10" and the port number as "502" in the client interface; ②Communication protocol parameter configuration: configure the parameter station number of Modbus TCP to "1" and the function code to "3"; ③Data sending configuration: Set the data address to be sent to "0x01" and the data value to "0x0A"; ④Data sending log record: automatically record the details of the sent data packet, including sending time, data content data value, and sending status "success"; If no stop signal is detected, data transmission continues; The fourth step is server configuration, as follows: ①Client communication address configuration: Enter the server IP address as "192.168.1.20" and the port number as "502" in the server interface. The server will automatically listen to all connection requests from the client. ②Communication protocol parameter configuration: The server configures the corresponding parameters according to the Modbus TCP protocol requirements; ③Data receiving configuration: The server sets the address range of receiving data to "0x01" to "0x10"; ④Data receiving log record: record the details of the received data packet, including receiving time, data value: "0x0A", receiving status "success"; If no stop signal is detected, data reception continues; The fifth step is to verify the test results, as follows: Check the data sending status through the client's log records; Verify data reception through server-side log records; If data sending and receiving are successful, it means that the Modbus TCP communication protocol works properly in the corresponding test environment.
