Brief description of the drawings
Constitute a part of accompanying drawing of the present utility model to be used for providing further understanding to of the present utility model, this practicality is new
The schematic description and description of type is used to explain the utility model, does not constitute to improper restriction of the present utility model.
In accompanying drawing：
Fig. 1 is the control circuit of the automatic change-over electric appliance with duplicate general purpose controller described in the utility model embodiment
Schematic diagram；
Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in figure 1, automatic change-over electric appliance with duplicate general purpose controller, including CPU processor, voltage acquisition mould
Block, conversion signal output module, the voltage acquisition module and conversion signal output module are all connected on CPU processor, institute
CPU processor is stated provided with CPU processor debugging interface, drive circuit output interface, parameter setting module input interface and people
Machine interactive module interface, for switching mechanism, different mechanisms may need different type of drive, therefore pass through drive circuit
Drive circuit needed for output interface connection switching mechanism, specific drive circuit can be designed into external interface circuit, lead to
Parameter setting module input interface Connecting quantity setup module is crossed, input circuit can be designed as dialling according to different input modes
The mode such as code or button, human-computer interaction module is connected by human-computer interaction module interface.
Software programming debugging module is connected by the CPU processor debugging interface, it is convenient to carry out subsequent development and upgrading.
The CPU processor is 32 bit processor chips, and the 32 bit processor chip has larger internal memory and wider
Addressing space, the increase of later stage function can be facilitated, and be unlikely to make software development to shrink with cold.
The CPU processor is also associated with controller power source module, failure indication module and network communication module, the control
Device power module processed is powered for controller, and the failure indication module includes LED light and buzzer warning, the net
The controller with communication function being applied to network communication module, conventional includes 485 and various industrial bus functions more.
Due to controller use 3.3V or 5V low-power consumption power supply mode, and scene often provide power frequency 220V or
380V voltages, it is therefore desirable to the controller power source module is connected at CPU by versatility stronger voltage conversion circuit
