提供散热 (blaze)#

You must provide sufficient heat dissipation to maintain a stable camera housing temperature, which is essential for reliable distance measurement.

一般准则#

由于每个安装条件都是独一无二的,因此 Basler 仅提供以下一般准则:

  • You should monitor the temperature of the camera housing using the Device Temperature (blaze) feature to make sure that the temperature doesn't exceed 50 °C.
  • Provide sufficient heat dissipation. Consider one of the following options:
    • Mounting the camera on a substantial, thermally conductive component that can act as a heat sink.
    • Using a fan to provide an air flow over the camera.

Automatic Temperature Control#

The blaze-101 camera is equipped with temperature sensors that measure the temperature of the laser board, the sensor board, and the CPU.

If temperatures at which safe operation of the camera can't be guaranteed anymore are reached, image acquisition will be stopped, which also means that the VCSELs are turned off. If this happens, try to reduce the temperature of the camera by lowering the exposure time or the frame rate or by providing more heat dissipation (see above).

Temperatures at which the image acquisition will be switched off:

  • Sensor board: 70 °C
  • Laser board: 85 °C
  • CPU: 85 °C

Restarting Image Acquisition After Automatic Acquisition Stop#

To find out when it is safe to turn image acquisition back on, follow these steps:

  1. Check the value of the TemperatureState parameter.
    If the state is Ok, the camera has cooled down sufficiently.

Alternatively, you can check the temperature at various locations in the camera:

  1. Set the DeviceTemperatureSelector parameter to the desired location.
  2. Get the value of the DeviceTemperature parameter.
    If the temperature has dropped sufficiently and is in the safe temperature range again, you can turn image acquisition back on.
  3. Execute the ClearLastError command.
  4. 开始图像采集。
