Intelligent virtual keyboard system for networked toll collection of expressway

Abstract

The invention provides an intelligent virtual keyboard system for networked toll collection of an expressway. A biological feature identification unit is used for collecting the biological feature ofa user and matching the biological feature of the user with the pre-stored standard biological feature of the user; a human-computer interaction interface unit presents a user operation unit interfaceand a virtual keyboard unit interface; a virtual keyboard unit receives the instruction information and/or text information input by the user through a virtual keyboard, sending the instruction information and/or text information to an application-layer transmission unit and making the text information automatically input into a corresponding option or table on a manual interactive interface; a voice recognition unit is used for recognizing voice information recorded by operating personnel; the application-layer transmission unit is used for transmitting a instruction to a protocol conversionunit; the protocol conversion unit is used for protocol conversion of the instruction; an interface unit is used for sending the instruction subjected to protocol conversion to a toll-collection-system control host computer. The system has the advantages of being low in cost and high in hardware portability, achieving cross-platform implementation, being easy and simple to operate, durable and the like.

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. Background technique [0002] Expressway network toll systems or parking toll plazas and other toll places generally use specially customized toll keyboards. The toll keyboard designed and produced by the expressway network toll system, in order to ensure the rapid passage of expressway toll vehicles, minimize the complicated operation process of operators, and the waiting time of drivers and passengers, the keyboards used in the expressway toll system are all adopted Special customization, the mechanical keyboard with keys generally between 38-80 keys. The metal shell is often painted and the internal silicone is waterproofed. The protection level can reach about IP65 and IK10. In addition, in order to ensure that the equipment can be used for a long time in harsh environments, cable...

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
