If when detecting that the current level of input port is consistent with predetermined level, then perform step:
S200: the count value of counter adds 1.
S300: the output level controlling the output port corresponding with the count value of counter is high level, other output port output low levels.
Time initial, it is pre-conditioned that equipment does not reach startup, and without the need to starting device, the level exported by each output port is low level.Time initial, the count value of counter is preset as 0.Pre-conditioned when often reaching one-shot, namely when the current level of each detection input port is consistent with predetermined level, the count value of counter adds 1, and the output level controlling the output port corresponding with the count value of counter is high level, such as, when the count value of counter is 1, control the output port corresponding with 1 and export high level, other output ports export as low level, when the count value of counter is 2, control the output port corresponding with 2 and export high level, other output ports export as low level, by the output level of the above-mentioned count value control output end mouth according to counter, realize output port and export high level in turn.
S400: the high level exported according to output port, is exported by the output of correspondence and starts control signal, control corresponding device start.
