Description

Technical Field

[0002] The coal pile sensor is a signal acquisition unit for coal pile protection on belt conveyors. When the coal pile sensor is normal, the coal pile output terminal of the coal level sensor outputs a high level. When the coal level increases and the sensor deflects a certain angle, the universal contact inside it is connected, the coal pile output is low, and the full coal indicator light turns on. After a short delay, the host execution relay is released to realize coal pile protection and send out a voice alarm signal at the same time.

[0003] Existing coal pile sensors are all installed on conveyors. When the coal pile sensors are in working condition, a lot of dust will penetrate into the joints of the cables.

It will interfere with the signal transmission inside the sensor, making the output signal unstable or erroneous, affecting communication with the control system, and causing the control system to be unable to correctly receive the coal pile signal and take corresponding control measures.
