Abstract
A level controller used CAN bus for communication was designed in this paper.It used 8-bit high speed MCU C8051F040.The principle of the structure of its hardware and software flow chart were expounded,and the simulation and practical control of advanced contol algorithms used double-holding water tank for object were carried through.The results of experiment show this controller can make excellent control of level odject,and it can also communicate with other CAN nodes and PC acted as a node of CAN bus.
