MCU (the 8bitMCU of STMicw Electronics in display module, STM8105K4 controller) UART interface and the main control module communication connection of standard, carry out data exchange, key scan and charactron or LCD shows that function allows user can arrange parameter and state is checked.
Ship type switch has manual and automatic two gears, when manual gear, directly being operated main contactor by switch lever and is connected with controlling power supply AC220V or disconnects, connecting and disjunction thus controlling major loop.
When automatic gear, having 3 kinds of control models, wherein a kind of pattern be set by main control module: 1) switch lever directly operates main contactor. AC220V power supply converts direct current to through rectifier bridge, when main control module detects handle position switch closing position, send and drive metal-oxide-semiconductor to control main contactor combined floodgate higher than the PWM ripple of 50% dutycycle, after closing position switch detects that major loop closes a floodgate, main control module sends and drives metal-oxide-semiconductor to realize the maintenance of catalyst lower than the PWM ripple of 50% dutycycle, reaches energy-conservation purpose. When fault separating brake, reclosing operation can be automatically performed after a delay.
2) on-off control is connect by the input interface in power supply and input/output module. In 1 pattern; Switch lever is when closing position, and the switching value on/off switch of main control module detection input port operates.
3) on/off switch is controlled by Remote. In 1 pattern; Switch lever is when closing position, and host computer is by the operation of RS-485 interface remote remote control on/off switch.
The priority that above control model handle position controls is the highest, it is ensured that local operation priority, status information all can be uploaded to host computer by RS-485 interface by main control module. Simultaneously by the input/output port output state in power supply and input/output module or warning.
