Recently, the Huai'an No. 2 ship lock of the North Jiangsu Canal has installed the “Automatic Alarm System for Ship Super-alarm Line Positioningâ€.
The system has been installed on the upstream of Huai'an No. 2 ship lock. Two sets of laser emitters and high-definition probes equipped with filters are installed in the super-warning line on both sides of the chamber wall. After the ship enters the gate, if it stops at the position of the super-warning line, the laser will form a contact on the ship. The high-definition probe will capture the laser contact and trigger the voice alarm device to continuously emit a voice warning, thus avoiding the ship in special weather. Next, stop by the light to the position of the super-warning line to eliminate potential safety hazards.
