Temperature State (Stereo ace)#

The Temperature State feature indicates whether the camera's internal temperature is normal or too high.

当温度过高时，需要立即冷却。

使用 Device Temperature 功能可确定相机的当前温度。

该功能的使用#

运作原理#

有关内部温度的信息通过以下参数提供：

  • The DeviceTemperature parameter value shows the current temperature at the core board of the camera. For more information, see the Device Temperature topic.
  • 即： BslTemperatureStatus 参数值告诉您相机的当前内部温度状态：
    • OK：设备温度在正常工作温度范围内。
    • Critical：设备温度接近或达到允许的最高温度。提供冷却。
    • Error：设备温度高于允许的最高温度。立即提供冷却。

The following additional parameters are available:

  • BslTemperatureStatusErrorCount 参数指示 temperature state 更改为 Error 的频率。
  • BslTemperatureMax 参数指示相机在操作过程中达到的最高温度。

当 TemperatureState 参数值为 Critical 或 Error 时，相机会提供一套机制来提醒用户并帮助保护相机。

这些机制会在不同的 device temperature 下生效，具体取决于警报级别以及相机是在升温还是在冷却。

信息

Normal camera operation requires that the temperature state stays at Ok and the housing temperature stays within the allowed range. To ensure this, follow the guidelines set out in the "Environmental Requirements" section of your camera topic. You can find your camera topic in the Basler Stereo ace section.

在高温下，相机可能会损坏，相机的寿命会缩短，并且图像质量可能会下降。频繁的高温事故也会缩短使用寿命。

升温路径和冷却路径

加热路径#

临界温度阈值#

When the device temperature reaches the critical temperature threshold (76 °C (168.8 °F)), the camera is close to becoming too hot.

In this situation, the BslTemperatureStatus parameter value changes to Critical.

信息

仅在 device temperature 降至临界温度阈值以下至少 4°C 之后，才能发送另一个临界温度事件。

超温阈值#

When the device temperature reaches the over temperature threshold (81 °C (177.8 °F)), the camera is too hot. The camera must be cooled immediately. Otherwise, the camera may get irreversibly damaged.

在这种情况下，将发生以下情况：

  • The BslTemperatureStatus parameter value changes to Error.
  • 相机的电流消耗会降低。
  • Image acquisition stops and can't be started until the device has cooled down.
  • The camera reports an over temperature error code.
  • The BslTemperatureStatusErrorCount parameter increases by 1.

信息

仅在 device temperature 降至超温阈值以下至少 4°C 之后，才能发送另一个超温事件。

冷却路径#

超温阈值#

When the device temperature falls below the over temperature threshold (81 °C (177.8 °F)), the following happens:

  • The BslTemperatureStatus parameter value changes from Error to Critical.

当设备温度下降到低于超温阈值 4°C 时，将发生以下情况：

  • Image acquisition can be started again.
临界温度阈值#

When the device temperature falls below the critical temperature threshold (76 °C (168.8 °F)), the following happens:

  • The BslTemperatureStatus parameter value changes to Ok.

相机的温度状态和内部温度正常，因此相机可以正常工作。

确定温度状态#

  1. Get the BslTemperatureStatus parameter value.
  2. 如果参数值为 Critical 或 Error，则必须冷却相机，直到参数值为 Ok为止。
