Software Signal Pulse#

相机的 Software Signal Pulse 功能可让您执行可用于多种目的的软件命令。

The feature serves as an alternative to software commands that are limited to a specific purpose, e.g., the TriggerSoftware command.

该功能的使用#

为什么使用软件信号脉冲命令#

Standard software commands can only be used for a single purpose. For example, you can use the TriggerSoftware command only to trigger the camera and the UserSetLoad command only to load a user set.

即： SoftwareSignalPulse command, however, can be used for multiple purposes. You can also use the command to control multiple camera features in a single operation.

运作原理#

支持的相机功能#

根据您的相机型号，Software Signal Pulse 功能可用于控制以下相机功能：

• 触发图像采集
  您可以在需要时触发相机。
• Sequencer (ace Classic/U/L USB)
  You can advance the sequencer, reset the sequencer, or both.
• Counter
  您可以计算特定相机事件的数量。
• Timer
  您可以配置计时器输出信号。

信号通道#

Depending on your camera model, up to three signal channels are available, e.g., SoftwareSignal1 and SoftwareSignal2.

如果要分别控制相机功能，使用不同的信号通道很有用。例如，您可以通过信号通道 1 触发相机，并通过信号通道 2 推进定序器。

使用软件信号脉冲命令#

To configure the SoftwareSignalPulse command:

1. Set the source of the desired camera feature to one of the available signal channels. For example, set the TriggerSource parameter to SoftwareSignal1.
2. 对要使用 Software Signal Pulse 功能控制的所有相机功能重复上述步骤。如果要同时控制多个功能，请为每个功能分配相同的信号通道。如果要使受控功能保持独立，请为每个功能分配不同的信号通道。

To execute a SoftwareSignalPulse command:

1. 设置 SoftwareSignalSelector parameter to one of the available signal channels, e.g., SoftwareSignal1.
2. Execute the SoftwareSignalPulse command.
   A software signal is sent. The signal uses the selected signal channel and executes the assigned action(s), e.g., advances the sequencer.

示例代码#

// Set software signal 1 as "path 0" trigger signal (sequencer reset)
camera.SequencerTriggerSource.SetValue(SequencerTriggerSource_SoftwareSignal1);
// Select software signal channel 1
camera.SoftwareSignalSelector.SetValue(SoftwareSignalSelector_SoftwareSignal1);
// Execute the command
camera.SoftwareSignalPulse.Execute();

INodeMap& nodemap = camera.GetNodeMap();
// Set software signal 1 as "path 0" trigger signal (sequencer reset)
CEnumParameter(nodemap, "SequencerTriggerSource").SetValue("SoftwareSignal1");
// Select software signal channel 1
CEnumParameter(nodemap, "SoftwareSignalSelector").SetValue("SoftwareSignal1");
// Execute the command
CCommandParameter(nodemap, "SoftwareSignalPulse").Execute();

// Set software signal 1 as "path 0" trigger signal (sequencer reset)
camera.Parameters[PLCamera.SequencerTriggerSource].SetValue(PLCamera.SequencerTriggerSource.SoftwareSignal1);
// Select software signal channel 1
camera.Parameters[PLCamera.SoftwareSignalSelector].SetValue(PLCamera.SoftwareSignalSelector.SoftwareSignal1);
// Execute the command
camera.Parameters[PLCamera.SoftwareSignalPulse].Execute();

#define CHECK(errc) if (GENAPI_E_OK != errc) printErrorAndExit(errc)

/* Set software signal 1 as "path 0" trigger signal (sequencer reset) */
errRes = PylonDeviceFeatureFromString(hdev, "SequencerTriggerSource", "SoftwareSignal1");

/* Select software signal channel 1 */
errRes = PylonDeviceFeatureFromString(hdev, "SoftwareSignalSelector", "SoftwareSignal1");
CHECK(errRes);
/* Execute the command */
errRes = PylonDeviceExecuteCommandFeature(hdev, "SoftwareSignalPulse");
CHECK(errRes);

# Set software signal 1 as "path 0" trigger signal (sequencer reset)
camera.SequencerTriggerSource.Value = "SoftwareSignal1"
# Select software signal channel 1
camera.SoftwareSignalSelector.Value = "SoftwareSignal1"
# Execute the command
camera.SoftwareSignalPulse.Execute()
