TYK2 is communicated, and the output voltage of communication setting TYK1 and TYK2 is passed through.
Electronic switch S1~S3 is controlled by S1ctr~S3ctr, and when carrying out rolling electricity output, the microprocessor of HDK is first closed
S1, S2 or S3 conducting of then setting out.Relay J1 is controlled by DO0, and effect is output electrical isolation, and J1 is closure under normal circumstances
State.What AIO and AUO was acquired is the electric current and voltage of HDK output, if AIO is more than setting value, J1 relay disconnects protection
Subsequent conditioning circuit and HDK.DO1~DO5 controls relay R1~R5 respectively, wherein R1~R3 be used to indicate respectively electronic switch S1~
The on or off state of S3.When corresponding electronic switch is connected in S1~S3, the corresponding relay closure of R1~R3；When
When corresponding electronic switch ends in S1~S3, the corresponding relay of R1~R3 is disconnected.Electricity output state is shaken in relay R4 instruction,
If triggered HDK (communication modes or manual mode), when output simulates and shakes electricity, relay R4 closure, shake electricity output terminates HDK
R4 is disconnected afterwards.Relay R5 be HDK indicating fault, when AIO collect output the excessive pipe of electric current break relay J1 while relay
Device R5 exports fault-signal.
HDK has 5 tunnel intakes, and wherein ST1, ST2 shake electricity output control for starting, and ST1 is to control on the spot, using by knob
Formula input, ST2 are long-range control.JDX is remote control/selection input on the spot.When JDX intake is closed state, i.e. DI3 is shape
State " 1 " i.e. high level is long-range state of a control, and ST2 receives long-range start command as starting control terminal at this time；When JDX open into
When amount is separated position, i.e. DI3 is state " 0 " i.e. low level, and for state of a control on the spot, ST1 connects as starting control terminal at this time
Receive start command on the spot.Pulse1, Pulse2 acquisition are knob output pulse, knob A, knob B as shown in figure 1, for setting
Surely it shakes the time of electricity output and shakes the voltage of electricity output.Microprocessor counts pulse by the way of edge counter
The step-length of rolling electric time and output voltage to adjust setting, are handed down to TYK1 and TYK2 by UART1 communication after setting,
The output voltage of oneself is adjusted in TYK1 and TYK2.The output time for shaking electricity is controlled by HDK.Optocoupler is opened all the way for HDK design
The rolling electricity output instruction of leakage output, shakes electricity condition for quickly exporting.The signal can quickly indicate to shake electricity output state, in group
It closes access three-phase when shaking electrical analogue output and shakes electric analog controller X4.
Tri- tunnel HDK Zhong You communicates serial ports, and UART1 is used to and TYK1, TYK2 of Regulation Control part carry out data communication；
UART2 is used to be communicated with HUM human-computer interaction module；UART3 shakes electric mould with three-phase when being combined rolling electrical analogue output
Quasi- controller X4 is communicated.
The output voltage output end of HDK is LoL, LoN, and access is devices under, is devices under as single phase power supply mode.
Shake primary control logic such as Fig. 4 of electricity output controller HDK.
In the present embodiment, shake electricity output controller HDK control method the following steps are included:
1) logic judgment first carry out it is long-range/judge judge whether DI3 is 1 on the spot, if so, being remote operation, execute step
It is rapid 2), if it is not, be then to control on the spot, execute step 3)；
2) when intake DI3 should be high level (JDX of Fig. 1), electricity output controller HDK is shaken at this time by shaking with three-phase
Electric analog controller X4 communication port UART3 reads TYK1 the output voltage U1 and TYK2 that three-phase shakes electric analog controller X4 setting
Output voltage U2, and read the rolling electricity duration T hd that three-phase shakes electric analog controller X4 setting；Then step 4) is executed；
3) when intake DI3 should be low level, the TYK2 for shaking electricity output controller HDK reading knob B setting at this time is set
Output voltage U2 and knob A setting rolling electric size time Thd；The output voltage U1 of electric adjustable pressure control module TYK1 is set
It is set to voltage rating output；Then step 4) is executed；
