Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the invention can
To be combined with each other.
The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments creates.
The present invention proposes a kind of design method, and the control of all electric motor types and excitation-type can be realized on a controller
Function processed has broken away from the maintenance of various controller product line, achievees the purpose that simplified factory products production and safeguards, while conveniently
The expansion and upgrading of subsequent product design.
The mentality of designing of the present invention is first to integrate the shared control characteristic of all dual-power transfer switch executing agencies, then
The special nature of different mechanisms is extract.
It functionally divides, software function of the invention includes：The acquisition of voltage signal, DI, DO, RTC, LED show,
LCD is shown, Modbus communicates, button and control logic.Rest part wherein other than control logic belongs to shared
Characteristic can keep preferable software conformance.
Condition judgment and driving output two parts in controller software control logic, belong to for different controllers
Special nature, then differentiation is needed to handle in the design.
The specific steps of the present invention include as follows：
First, characterization logic is shared
1st, the shared control characteristic of dual-power transfer switch controller software is designed first, on condition that there are one overall frames
Frame figure, as shown in Figure 1.Regardless of Double-power controller, its most basic software frame can be reduced to shown in Fig. 1
System-based frame, can all include parameter setting, input and output, show and haul oneself willingly into runback, haul oneself willingly into not runback and standby each other
Operating mode.
2nd, shown in Fig. 1 it is system overall framework, the control detail section not shown in figure, the present invention is individually
It sums up and, be summarized in analyzing logic control part.The part becomes control logic block diagram, as shown in Figure 2.It includes communication and controls
System, remote control, fire-fighting control are forbidden controlling and automatically control five parts.Wherein communication control, remote control, fire-fighting
It controls and control is forbidden to belong to general controls, it can be by Programming to together.And automatically control and belong to Special controlling,
It needs to realize different applications according to different ontologies, be described in detail below.
2nd, peculiar control logic
Divide from structure, dual-power transfer switch includes two positions product (main electric position, standby electric position) and the production of three positions
Product (main electric position, standby point position, double minutes positions).Divide from type of drive, dual-power transfer switch is divided into electric motor type and excitation
Formula product.The control mode that different product has its special.
1st, two positions production interchange logic chart is as shown in Figure 3.When main electric fault, controller starts transfer delay timing,
After transfer delay reaches T1 setting values, controller driving mechanism is transformed into standby electric power supply.
2nd, three position production interchange logic charts are as shown in Figure 4.When main electric fault, controller starts transfer delay timing,
