Method, device, program product and storage medium for adaptive recognition of fuel dispenser model and communication protocol
By extracting the data frame features of gas and fuel dispensers and using fingerprint database comparison and difference table detection, the model of the gas and fuel dispenser is automatically identified and the communication protocol is loaded. This solves the problem of communication protocol binding deviation in the networking of gas and fuel dispensers from multiple manufacturers and of multiple models, and improves the reliability and accuracy of the communication link.

AI Technical Summary
In existing technologies, the mixed networking of refueling and gas filling machines from multiple manufacturers and of multiple models in gas stations leads to deviations in communication protocol binding, resulting in communication links failing to be established correctly or abnormal business interactions, and low communication reliability.
By acquiring data frames actively transmitted by gas and refueling machines, extracting syntactic and temporal features, constructing detection commands using a preset fingerprint database and a difference table, the machine model is automatically identified and the corresponding communication protocol is loaded, ensuring the reliability of the communication link.
Without human intervention, it automatically identifies the model of the gas pump and loads the correct communication protocol, improving the reliability and accuracy of communication link establishment and adapting to mixed networking scenarios with multiple manufacturers and models, as well as firmware upgrade scenarios.
