The vehicle remote system of checking includes that car networking subsystem and vehicle panoramic check subsystem.Car networking subsystem is used
In receiving and vehicle remote input by user forwarded to check instruction;Vehicle panoramic check subsystem for receive by car networking subsystem
The long-range of system forwarding checks instruction, and checks that vehicle panoramic video information is sent to car networking subsystem by instruction based on long-range,
Wherein, car networking subsystem is additionally operable to being sent to user after vehicle panoramic video information process.
Vehicle panoramic checks that existing 360 panoramic parking system can be used in subsystem, by be mounted on vehicle body it is forward and backward, it is left,
Right four-way CCD camera acquires image information, and to being sent to user through car networking subsystem after Image Information Processing.In this way, with
Family can be checked that subsystem is timely by car networking subsystem and vehicle panoramic, easily check that the real time panoramic of vehicle periphery regards
Frequency information.Real-time panoramic video information herein includes the real-time pictures or real-time video information of vehicle periphery.
According to one embodiment of present invention, which includes user terminal, backstage and T-BOX terminals.Its
In, user terminal for it is input by user it is long-range check instruction and receive vehicle panoramic video information, such as equipped with checking program
The mobile phone of interface APP;For remotely checking instruction and vehicle panoramic video information by data link forwarding, this is from the background on backstage
The data processing system of (telecommunication service) is serviced with Telematics;T-BOX terminals are used to receive backstage forwarding
It is long-range to check that instructing and forward it to vehicle panoramic checks subsystem, and vehicle panoramic is checked into the vehicle that subsystem is sent
Backstage is sent to after panoramic video information processing, which can be by improving the T-BOX structures on existing vehicle
It arrives.
According to one embodiment of present invention, T-BOX terminals are regarded including the first transceiver module, the second transceiver module, first
Frequency transmission module and compression module.Wherein, the first transceiver module and background communication check finger for receiving the long-range of backstage forwarding
It enables and sends vehicle panoramic video information to backstage;Second transceiver module checks that subsystem and first is received with vehicle panoramic respectively
Module communication is sent out, for checking that subsystem sent that it receives from the first transceiver module remotely checks instruction to vehicle panoramic;Pressure
Contracting module is connect with the first transceiver module and the first video transmission module respectively, the vehicle for exporting the first video transmission module
It is sent to the first transceiver module after the processing of panoramic video Information Compression.
According to one embodiment of present invention, which includes third transceiver module and decompression module, wherein the
Three transceiver modules are used to send to backstage and remotely check instruction and receive vehicle panoramic video information from backstage;Decompression module
It is communicated with third transceiver module, the vehicle panoramic video information decompression for that will receive.It can be by user terminal
Setting APP interface routines are sent to third transceiver module remotely checks instruction, and receives from decompression module and received and dispatched by third
Module receive, by the vehicle panoramic video information after decompression module decompression processing.Vehicle panoramic video letter after decompression
Breath can be shown in the user terminal with video display function.

Video broadcast signal) or LVDS (Low-Voltage Differential Signaling, low-voltage differential signal) and corresponding
Other interfaces be attached.The system further includes checking middle control screen that subsystem is connect with vehicle panoramic, for showing vehicle
Peripheral information.
According to another aspect of the present invention, the vehicle remote inspection method in a kind of car networking is additionally provided, such as Fig. 2 institutes
It is shown as method flow diagram according to an embodiment of the invention, Fig. 3 is corresponding algorithm flow chart, below with reference to Fig. 2 and Fig. 3
It is next that the present invention is described in detail.
It is step S100 first, sending vehicle remote to car networking subsystem checks instruction.For example, user can pass through hand
Machine APP forms send vehicle remote to car networking subsystem and check instruction.Specifically include following process.It is to pass through vehicle first
User terminal in Networking subsystems inputs service password;Then, it as service password is correct, is then inputted by user terminal long-range
It checks instruction, otherwise returns and re-enter;Finally, the backstage in car networking subsystem, which receives, remotely checks instruction and by its number
Remotely check instruction to T-BOX terminals according to link forwarding.
Followed by step S200, vehicle remote is checked that instruction is transmitted to vehicle panoramic and checks subsystem by car networking subsystem
System.Specifically, remotely will check that instruction is forwarded to vehicle panoramic and checks subsystem by the T-BOX terminals in car networking subsystem.
Followed by step S300, vehicle panoramic checks that subsystem checks that instruction is transferred vehicle panoramic and regarded based on vehicle remote
Vehicle panoramic video information is simultaneously sent to car networking subsystem by frequency information.Specifically, T-BOX terminals receive and compression processing vehicle
Panorama checks the vehicle real scene video information that subsystem is sent;T-BOX terminals believe the vehicle real scene video after compression processing
Breath is sent to backstage;Vehicle real scene video information after compression processing is transmitted to user terminal by backstage.
It is finally step S400, vehicle panoramic video information is forwarded to user by car networking subsystem.Specifically, user is whole
End is by the vehicle panoramic video information decompression processing after the compression processing of reception to be shown to user.
