A loose cross-connection architecture of precision time synchronous transaction device and law-enforcement device applied on electronic tolling systems

The present invention relates to a loose cross-connection architecture of precision time synchronous transaction device and law-enforcement device applied on electronic tolling systems. It is a simple, independent, highly efficient, and highly accurate matching process architecture (a type of loose cross-connection network) presented between two independent sub-systems, including a transaction device and a law-enforcement device, in which a set of communication cables is applied for data communication. Time synchronization is applied between the two devices for the matching between an input data of the transaction device and an input data of the law-execution device based on the same time base. In other words, each transaction data must be allocated correctly to a certain vehicle. The communication cables is used for data transmission as well as time synchronization.
