Application of Embedded System in Construction Machinery

Developed especially for the specific requirements and standards of construction and automotive industries for vehicles and machines to work in the field, modern controller in construction machinery is usually made up of several different electric control units (ECUs) based on the embedded system. The different ECUs configure the control area network (CAN) in construction machinery by CAN-bus. They work independently as measuring, driving or operating control device for sensor-actuator management and execute a number of tasks independently or cooperated with each other in real time. Data exchange between the ECUs or controllers could be realized via the RS232 or the CAN-Bus interface. Equipped with the embedded system in controller, in complex task of construction, machineries and vehicles will be integrated management and distribution rationalized by the remote control center using telecommunications technology via networks, so that the process could be controlled real-time and circulated in order.
