Visual host system design and development (Halcon WinForm)

• This paper introduces the idea of how to realize a visual upper scheme configuration system , be based on C# winform, Native controls for interface design , technological process UI Interaction , And operator calls , Equipment communication, etc .
• The design idea is roughly based on the operator of visual Library , Encapsulate the operator into a single tool node , For example, image import , Color conversion , Area rendering , Threshold analysis , Result judgment and so on , You can customize the input parameters of the node according to the project situation , Operation parameters , So as to get the execution result . In addition, the device communication drives the flow of global variables , The output of the final result completes the whole detection work .
• The visual upper module is roughly divided into the following modules
  1. Program process management
  2. Process node relationship
  3. Global variable management
  4. Image drawing preview function
  5. Equipment communication control
  6. Node operator execution method
  7. Results output , Image output
• Let's start with a few renderings . Subsequent articles will analyze the functions from these blocks .
• Data objects are ： programme , technological process 、 Process nodes 、 Node basic information 、 Equipment information 、 Device event information 、 Operator matching function 、 Global variables 、 wait
