Abstract

The invention discloses a vehicle-mounted terminal communication method applied to engineering machinery vehicle networking. The vehicle-mounted terminal communication method includes a method for internet access communication between a vehicle-mounted terminal unit and a remote server unit based on wireless second-generation or third-generation communication and a method for communication between the vehicle-mounted terminal unit and a local function unit. The method for communication between the vehicle-mounted terminal unit and the local function unit includes: a method for communication between the vehicle-mounted terminal unit and a detecting and maintaining computer unit; a method for communication among the vehicle-mounted terminal unit, an engine electric control unit and a vehicle electric control unit which are based on CAN (control area network); a method for communication between the vehicle-mounted terminal unit and a geographical position information detecting unit based on RS232 (recommend standard 232); a method for communication between the vehicle-mounted terminal unit and a vehicle body balance-degree or gradient detecting unit based on RS485; and a method for communication among the vehicle-mounted terminal unit and human-interactive input and output units. The vehicle-mounted terminal achieved by the methods can be applied to various engineering applied vehicles, transmission and management of vehicle state data can be realized, requirements and functions of a vehicle networking system can be met, and conditions for sharing and serving engineering vehicle data are provided.

Description

technical field [0001] The invention belongs to the fields of engineering vehicles, mining machinery and equipment manufacturing, and relates to a communication method for a vehicle-mounted terminal unit of an engineering vehicle and a terminal device for realizing the communication method. Background technique [0002] Construction machinery vehicles include excavators, rotary drilling rigs, rock drilling rigs, loaders, cranes, pile drivers, road rollers, bulldozers and other engineering vehicles, which play a huge role in major engineering construction, mining and other fields. Compared with other vehicles, it is more complex in function and has a harsher working environment. The vehicle works under heavy load for a long time, there are various potential safety hazards, and it is easy to cause production accidents. With the development of the economy and the needs of engineering construction, higher demands are put forward for the whole process of vehicle dispatching, veh...
