Electric parameters collection and control based on CAN bus

The thesis introduced a kind of electric power parameter collecting and supervising system which is based on CAN field bus. The system is composed of host computer, CAN adapter, and intelligent nodes with networked bud interface. Each artificial intelligence controlling node is a field measuring and controlling circuit which is composed of a microcontroller 80C196KC and a electric parameter collecting CMOS t chip CS5460A. The thesis introduced the composing of the interfacial circuit of CAN field bus which is composed of a new type of independent CAN bus controller SJA1000 and the hardware designing of field controlling circuit particularly. The practices show that the system can be used to realize the high precision data collecting and the efficient controlling of ten artificial intelligence controlling node within the electricity assigning range of 5km. It will make the numeral collecting and the artificial intelligence managing of the parameter of the electricity assigning system come true , and it will improve the reliability and the efficiency of the running of the electricity assigning system.
