The signal output port of the second confirmation signal input port 24, second self-inspection relay 22 of the signal output port connection second controller 2 of the first self-inspection relay 12 connects the first confirmation signal input port 14 of the first controller 1.
In the present embodiment, the first controller 1 and second controller 2 are 8808 model intelligence and machine controller, produced and introduce to the market, and the first controller 1 and second controller 2 all adopt factory setting by applicant.After diesel-generator set control system energising, the first controller 1 and second controller 2 electrifying startup.The startup if the first controller 1 has taken the lead in, whether first detect the first detection signal input port 13 has pulse signal to input, as pulse-free signal triggers input, the signal output port of the first main relay 11 sends a lasting pulse signal to the second detection signal input port 23 of second controller 2, makes second controller 2 become spare controller.
After second detection signal input port 23 of second controller 2 has detected pulse signal input, second self-inspection relay 22 of second controller 2 is triggered, and the signal output port of the second self-inspection relay 22 sends a lasting pulse signal to the first confirmation signal input port 14 of the first controller 1.
First confirmation signal input port 14 of the first controller 1, after confirmation has pulse signal to input, confirms that second controller 2 exists and is in stand-by state.
If by the second detection signal input port 23, second controller 2 detects that the input of pulse signal is interrupted, then second controller 2 becomes primary controller, namely transfers parallel operation state to from stand-by state.
After diesel-generator set control system energising, the first controller 1 and second controller 2 electrifying startup.The startup if second controller 2 has taken the lead in, whether first detect the second detection signal input port 23 has pulse signal to input, as pulse-free signal triggers input, the signal output port of the second main relay 21 sends a lasting pulse signal to the first detection signal input port 13 of the first controller 1, makes the first controller 1 become spare controller.
After first detection signal input port 13 of the first controller 1 has detected pulse signal input, first self-inspection relay 12 of the first controller 1 is triggered, and the signal output port of the first self-inspection relay 12 sends a lasting pulse signal to the second confirmation signal input port 24 of second controller 2.
