Automatic meter-reading device

Automatic meter-reading device

The device serves (1) for automatically monitoring a metering device (101) such as an electric-power meter. It comprises a first window (21) for passage of light to and from the metering device (101), and a second window (22) that allows an observer (9) to visually read the metering device (101). It...

Zusammenfassung:The device serves (1) for automatically monitoring a metering device (101) such as an electric-power meter. It comprises a first window (21) for passage of light to and from the metering device (101), and a second window (22) that allows an observer (9) to visually read the metering device (101). It further comprises an infrared-light source for illuminating the metering device (101), and an image detector (4) for detecting an image of the metering device (101). A dichroic, semi-transparent mirror (5) reflects the infrared light scattered from the metering device (101) towards the image detector (4), while it transmits visible light towards the observer (9). Thus, the image detector (4) is shielded from undesired light of environment that could disturb the image. The device (1) may further comprise anti-reflection means for preventing a direct reflection of illuminating light (30) reaching the image detector (4). The device may be mounted on an existing counting mechanism (10) for its automatic monitoring, while a visual reading is still possible.
