Description
Technical field
The present invention relates to a kind of board information terminals, and in particular to a kind of vehicle-mounted cloud service information terminal of commercialization.
Background technology
Existing board information terminal is broadly divided into two major classes by function, and one kind is to be to fill navigation equipment after passenger car
It is main, based on the another kind of monitoring positioning with commercial car.The navigation amusement equipment of passenger car have video playing, document process and trip
The functions such as play, the monitoring positioning product of commercial car mainly use its to monitor positioning function, are widely used in taxi, long-distance
On the commercial operations vehicle such as passenger traffic, fire fighting truck, police car, ambulance, Tour Bus.
Riding vehicle mounted guidance amusement equipment have the function of that music, navigation etc. are abundant, and the interface of automobile itself is relatively simple,
It is easy for installation, and equipment is integrally biased to amusement function, can provide preferable experience to the user；But the stability of this kind of equipment is owed
Good, equipment interface is not abundant enough in addition, cannot be satisfied vehicle-mounted 7*24 hours of requirement.In contrast, the monitoring of commercial vehicle
Positioning product stability is preferable, but under the limitation of existing equipment function, and the user of such product can only passively adopter
Reason, it is dull with the interaction of equipment, and then user is made to generate resentful attitudes, this kind of design right and wrong for not considering user's impression
It is often not humane, it is urgently to be resolved hurrily the problem of being short of in the interaction and experience of user.In addition, commercial car is to data transmission
It is required that it is more much higher than common passenger car, it is quite high to the signal condition requirement of communication network, especially for domestic communication
The plurality of communication schemes and communication service that operator provides differ the drawback irregular with coverage condition there is transmission rate,
Cause existing commercial board information terminal when communication network signal is second-rate, can not automatic adaptation obtain it is continual and steady
Signal transmission capabilities.
With the fast development of commercial car demand increased with exchange technology, existing commercialization board information terminal is
Actual use cannot be met, facts proved that, commercial board information terminal must follow up the demand of user, carry out further skill
Art is reformed, but is limited to the immature of standard hardware platforms and software phase lock loop, so that commercial on-vehicle information acquisition is continued steady
Fixed data signal transmission ability, and meet functional requirement and effective and hommization service is provided that user is become increasingly abundant
These problems are preferably solved not yet, also become the problem in the field always.
Invention content
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of vehicle-mounted cloud service information terminal, the terminals gram
Having taken existing commercial board information terminal automatic adaptation and can not keep continual and steady data signal transmission ability and ignorance
Man-machine user experience and use feeling, can not provide amusement and information communication facility and hardware platform for user and software is logical
With the bad problem of property.
The present invention adopts the following technical scheme that achieve the above object：A kind of vehicle-mounted cloud service information terminal of commercialization, the end
End include main control unit, automobile power source processing unit, vehicle signal detection unit, communicate positioning unit, interface unit, bluetooth/
