Description

Technical Field

[0001] This invention relates to the field of electric heat tracing control technology, and in particular to an electric heat tracing cable monitoring system. Background Technology

[0002] With global warming, polar regions are becoming increasingly suitable for ship navigation. Ships navigating in polar or ice-covered areas are highly susceptible to icing on their exposed surfaces, particularly around bridge windows, vents, hatch covers, antennas, deck passageways, ladder handrails, open deck piping, and deck machinery. This icing negatively impacts the ship's structure, equipment, systems, and the safety of crew members. Various de-icing solutions exist, but manual or steam de-icing methods are ineffective, time-consuming, and can damage passageways and decks. Electric heating tape, a mature product, is widely used for pipe freezing, floor heating, large-scale venue heating, and snow melting in public areas such as bridges and tunnels. Therefore, using electric heating tape to prevent ship icing is a feasible and effective solution.

[0003] With the increasing application of electric heating cables, the quantity of electric heating cables used, and the number of electric heating cable circuits, the monitoring and routine maintenance of electric heating cables are becoming increasingly important. Currently, existing electric heating cable monitoring systems mainly include an electric heating control cabinet, an electric heating cable junction box, an ambient temperature sensor, and an electric heating circuit. The electric heating cable connects to the junction box, which in turn connects to the control cabinet via a power cable. The ambient temperature sensor transmits the ambient temperature to the control cabinet via a signal cable, and the control cabinet controls the power supply to or from the electric heating cable. However, this type of electric heating cable monitoring system lacks remote monitoring; it can only provide comprehensive alarms from a remote location.
