Detailed Description
It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict, and the present invention is further described in detail with reference to the accompanying drawings and specific embodiments.
Please refer to fig. 1-10, the utility model discloses a novel on-vehicle interconnection screen casting box includes USB interface, microprocessor ARM, microcontroller MCU, storage module, power supply circuit, panorama video processing module, 4G module, bluetooth/WIFI module, navigation orientation module.
And the microprocessor ARM is communicated with the microcontroller MCU through a serial port. The microcontroller MCU is a control center of the whole box and controls switching of various sources and detection and control of the vehicle-mounted machine interface.
The USB interface is electrically connected with the microprocessor ARM and the power circuit. The storage module, the panoramic video processing module, the 4G module, the Bluetooth/WIFI module and the navigation positioning module are electrically connected with the microprocessor ARM. The utility model discloses only with USB _5V just can for novel on-vehicle interconnection throw the screen box power supply can, plug-and-play.
The power supply circuit supplies power to the panoramic video processing module, the microcontroller MCU, the microprocessor ARM, the storage module, the 4G module, the Bluetooth/WIFI module and the navigation positioning module.
The utility model discloses accessible USB interface reads USB flash disk audio frequency and video, does data processing through microprocessor ARM and decodes, transmits audio frequency and video for former car (accessible USB data line with take Carplay, Carlife, the former car of Android function is connected) through the USB data line again, and former car enlargies back drive external loudspeaker. After being processed, the panoramic video signal enters a microprocessor ARM for data processing and decoding, and is transmitted to an original vehicle host through a USB data line to display an image.
The utility model discloses accessible wiFi or bluetooth or USB link to each other with the cell-phone, can pass through the application of cell-phone the utility model discloses a novel on-vehicle interconnection throw the screen box and transmit and show on the former car screen host computer, realize that the cell-phone is used to throw the screen to the car machine.
The utility model discloses do not have the physics button, can utilize the content that the touch control box of former car screen sent according to the agreement.
In one embodiment, the panoramic video processing module employs a TP9930 panoramic chip. During specific implementation, the panoramic video input signal is transmitted to a TP9930 panoramic chip of the box in a 4-channel 720P AHD analog signal mode, the analog signal is converted into a BT1120 video digital signal to be input into a GPU of a graphics processing part of a microprocessor ARM for data processing, and after the video is processed and decoded by the GPU, the video is transmitted to an original vehicle machine through a USB for display.
