Intrinsically-safe camera arrangement for operation in potentially explosive area of underground mining, has data transmission unit with fiber optic cable, which is connected to external processing device

摘要

The arrangement (1) has a housing (2) with a housing cover (3), which includes a transparent glass plate (30). A camera (4) i.e. charge coupled device (CCD) camera, is accommodated inside the housing, where the camera is arranged on a guide rail (6). A data transmission unit transmits image data e.g. color image data, recorded by the camera to an external processing device. The data transmission unit includes a fiber optic cable, which is connected to the processing device. The cover includes a pneumatic cleaning device to clean the glass plate. A microphone is integrated in the arrangement.
