As there are shortcomings in the prior art, the invention provides a highway intelligent charging system and a corresponding intelligent charging method. The system is based on a lane charging facility, a receipt printer, a server, a charging terminal, and other hardware equipment. Personalized charging setting can be performed according to different sections, different lanes and different areas. Rate adjustment can be performed according to different charging strategies and weight strategies. The parameters of different lanes can be configured, managed and controlled remotely or locally. Data is transmitted by data transmission middleware. The response speed of data uploading and sending control is increased. High reliability and safety of data and charge are ensured through a hot-standby strategy.
