An intelligent virtual keyboard system for networked expressway toll collection

Abstract

The present invention proposes an intelligent virtual keyboard system for expressway networking charges, including: a biological feature recognition unit collects the user's biological features and matches them with the pre-stored user's standard biological features; the human-computer interaction interface unit presents the user operation unit interface and the virtual keyboard Unit interface; the virtual keyboard unit receives the instruction information and / or text information input by the user through the virtual keyboard, sends the instruction information and / or text information to the application layer transmission unit, and automatically inputs the text information to the corresponding option or form; the speech recognition unit recognizes the voice information entered by the operator; the application layer transmission unit forwards the instruction to the protocol conversion unit; the protocol conversion unit converts the instruction to the protocol; the interface unit sends the protocol converted instruction to the charging System control host. The invention has many characteristics such as low cost, high hardware portability, cross-platform realization, simple and fast operation, and durability.

Description

technical field [0001] The invention relates to the technical field of intelligent virtual keyboards, in particular to an intelligent virtual keyboard system for expressway networking charges.

Problems solved by technology

In addition, the customized keyboards used in the expressway networking toll collection system vary greatly due to the different needs, working methods, and toll standards of each province. Even for different toll sections or places in the same province, the toll used The keyboard is also different, which makes the existing paid keyboards intricate and complicated. Because they are all customized, the price of this special keyboard remains high, and the initial investment cost is very high. It can only be completed with a lot of cost investment, the cycle time is long, and the portability and versatility are poor

In addition, due to the special toll keyboards for expressways are now all mechanical keyboards, there are many shortcomings and deficiencies such as easy damage or keycap falling off after long-term percussion.

It has made the existing charging keyboard unable to keep up with the trend and be eliminated
