ABSTRACT: This paper aims to design a
MCU-based smart contactor system, which will realize functions of real time
surveillance of contactors’ work status and data exchange with host computer,
thus instantly reflect different status of the system. In case of abnormal
status such as over-current or under-voltage, the contactor will be able to
automatically cut off power supply to protect electrical load and the circuit.
Through ARINC485 bus, system computer will collect and record contactor
parameters, including contact voltage, contact current, supply frequency,
contact temperature and contact status to provide critical data to the
examination and repair of contactors.
