# AxiOmron.PcbCheck
|
||
|
||
基于 `.NET 8 + WPF + MVVM Toolkit + Generic Host/DI + NLog` 的 PCB 目检上位机示例工程，包含 PLC 通信、扫码枪触发、SFTP 文件校验、安灯报警和运行态监控。
|
||
|
||
## 项目结构
|
||
|
||
```text
|
||
Axi_Omron/
|
||
src/
|
||
AxiOmron.PcbCheck/
|
||
tests/
|
||
AxiOmron.PcbCheck.Tests/
|
||
docs/
|
||
AxiOmron.PcbCheck.slnx
|
||
```
|
||
|
||
主程序位于 [src/AxiOmron.PcbCheck](d:/Dev/Codes/MFD_Solution/Axi_Omron/src/AxiOmron.PcbCheck)，测试位于 [tests/AxiOmron.PcbCheck.Tests](d:/Dev/Codes/MFD_Solution/Axi_Omron/tests/AxiOmron.PcbCheck.Tests)。
|
||
|
||
## 技术栈
|
||
|
||
- `.NET 8` / `WPF`
|
||
- `CommunityToolkit.Mvvm`
|
||
- `Microsoft.Extensions.Hosting`
|
||
- `NLog`
|
||
- `IoTClient` Modbus TCP
|
||
- `SSH.NET`
|
||
- `HandyControl`
|
||
|
||
## 配置说明
|
||
|
||
主配置文件位于 [src/AxiOmron.PcbCheck/appConfig.json](d:/Dev/Codes/MFD_Solution/Axi_Omron/src/AxiOmron.PcbCheck/appConfig.json)。
|
||
|
||
当前 PLC 相关默认配置示例：
|
||
|
||
- `Plc.Host`: `127.0.0.1`
|
||
- `Plc.Port`: `502`
|
||
- `Plc.UnitId`: `1`
|
||
- `Plc.PollIntervalMs`: `200`
|
||
- `Plc.ReleasePulseMs`: `500`
|
||
- `Plc.ReleaseAckTimeoutMs`: `2000`
|
||
- `FileCheck.DeleteMatchedFileAfterPlcAck`: `false`；启用后仅在收到 PLC 放行应答时删除本次精确命中的产品 ID 文件
|
||
|
||
点位映射示例：
|
||
|
||
- 输入点位
|
||
- `PcbArrived = 0`
|
||
- `PlcReset = 1`
|
||
- `PlcAckRelease = 2`
|
||
- 输出点位
|
||
- `PcBusy = 51`
|
||
- `ReleasePermit = 52`
|
||
- 寄存器
|
||
- `ResultCode = 0`
|
||
|
||
系统设置页可修改 PLC 参数，界面入口在 [SystemSettingsPage.xaml](d:/Dev/Codes/MFD_Solution/Axi_Omron/src/AxiOmron.PcbCheck/Views/Pages/SystemSettingsPage.xaml#L58)。
|
||
|
||
注意：配置保存后会写入运行目录下的 `appConfig.json`，当前界面提示为“重启应用后完全生效”。
|
||
|
||
## 构建与运行
|
||
|
||
```powershell
|
||
dotnet restore .\src\AxiOmron.PcbCheck\AxiOmron.PcbCheck.csproj
|
||
dotnet build .\src\AxiOmron.PcbCheck\AxiOmron.PcbCheck.csproj -c Debug
|
||
dotnet run --project .\src\AxiOmron.PcbCheck\AxiOmron.PcbCheck.csproj -c Debug
|
||
dotnet test .\tests\AxiOmron.PcbCheck.Tests\AxiOmron.PcbCheck.Tests.csproj
|
||
```
