Abstract

The invention discloses a vehicle-carrying terminal based on CANBUS information gathering, distributing and control, which is characterized by the following: constructing LAN of vehicle through main control unit CAN interface; utilizing GPRS or CDMA mode to connect main control unit through RS 232 interface; interconnecting vehicle-carrying terminal and internet through wireless communicating network and PPP dial network protocol in the inserted Linux operational system; realizing the hardware combination of real-time information gathering, distributing and control. The information contains video signal, character prompting information and sensor digital signal. the video signal gathering and distribution is realized according to preset pattern or condition triggering pattern. The real-time digital gauge is distributed through memory or wireless network, which coordinates the operation through controlling the sensor in the LAN of vehicle.

Description

technical field [0001] The present invention constructs a vehicle local area network through the CAN port of the main control unit, uses GPRS or CDMA module, connects with the main control unit through the RS232 port, and uses the PPP dial-up network protocol in the embedded Linux operating system to make the vehicle-mounted terminal pass wireless The communication network and the Internet are interconnected to realize the intelligent device of information collection, release and control. Background technique [0002] At present, there is no device on the market that uses CANBUS to build a vehicle local area network for information collection, distribution and control. Contents of the invention [0003] The present invention constructs the local area network of the vehicle through the CAN port of the main control unit, utilizes GPRS or CDMA module, connects with the main control unit through the RS232 port, and in the embedded Linux operating system, through the PPP dial-u...
