Description
Technical field
The present invention relates to Internet of Things field, and in particular to intelligent public transportation dispatching and data transmission system.
Background technology
In recent years, urban road infrastructure and the contradiction of transport need, it is corresponding by being provided to vehicle
Intelligent information service is one of effective important means alleviated urban transportation and blocked.
Automobile information service based on Internet of Things refers to by cordless communication network, integrate various types of communication ability, information and
Service Source, by open and abundant interface, using location-based location technology and electronic map, using car-mounted terminal as load
Body, safety, communication, navigation, amusement and the maintenance in driving are provided for human pilot, and realize the driving row to driver
For monitoring and vehicle-state management.
But scheduling of the existing public traffic management platform to vehicle is relied primarily on and be accomplished manually, intelligence degree is low, data
Efficiency of transmission is low, and public transport be transferred to management platform in-car image definition it is not high, it is impossible to well support video recording check and
Case is collected evidence.
The content of the invention
In view of the above-mentioned drawbacks of the prior art, the invention provides a kind of intelligent public transportation dispatching and data transmission system
