The invention discloses a CAN (controlled area network) communication based switching unit of redundant controllers for an emergency diesel generating set. The CAN communication based switching unit comprises a first controller and a second controller; a main relay and a first self-check relay are integrated to the first controller; each of the main relay and the first self-check relay is provided with a signal output port; a second self-check relay is integrated to the second controller and provided with a signal output port; the first controller is further provided with a first Confirm signal input port; the second controller is further provided with a detection signal input port and a second Confirm signal input port; the signal output end of the main relay is connected with the detection signal input port through a CAN bus; the signal output port of the first self-check relay is connected with the second Confirm signal input port through the CAN bus; the signal output port of the second self-check relay is connected with the first Confirm signal input port through the CAN bus.
Description
technical field [0001] The invention relates to a redundant controller switching device for an emergency diesel generator set using CAN communication in the field of diesel generator sets. Background technique [0002] Diesel generator set is a kind of power equipment that uses diesel engine as prime mover and drives synchronous generator to generate electricity. This is a power generation device with quick start, convenient operation and maintenance, low investment and strong adaptability to the environment. Diesel generator sets are mainly divided into four parts: diesel engine, generator, control system, and electrical system. The control system controls the operation of the diesel generator set according to the set working state and has functions such as alarm and shutdown in fault status. The control system of the diesel generator set can accurately and quickly adjust the operation of the diesel generator set, and keep all electrical equipment in good working condition...
