In modern urban construction, underground pipelines serve as the operational hub for the city'lifeline'Its precise detection and management are directly related to the operational efficiency and safety of municipal planning, power supply, communication networks, and other fields. Shandong Hongcheng Automation Technology Co., Ltd. launchedHCT3000The intelligent underground pipeline detector (also known as pipeline instrument, track instrument), with its multifunctional integration and high-precision detection capability, has become the core tool for industry users to solve the problem of underground pipeline detection.

1、 Core function: Trinity, precise positioning

HCT3000The intelligent underground pipeline detector integrates three core functions: pipeline path detection, cable recognition, and fault diagnosis, forming a complete solution from path positioning to fault diagnosis:

Pipeline path detection

By applying electromagnetic signals of a specific frequency to underground pipelines through a transmitter, the receiver captures the reflection characteristics of the signal using the principle of electromagnetic induction. Combined with narrowband filtering technology, it effectively suppresses interference from adjacent pipelines, achieving precise positioning of metal pipelines and non-metallic pipelines with metal marking lines. Detection depth can reach5Meter, suitable for pipeline survey and depth measurement in complex environments.

Intelligent cable recognition

In response to the identification needs of power cable engineers,HCT3000Support distinguishing between live and power-off cables. Users can pre calibrate up to at the transmitting end20A cable is used, and the receiving end automatically identifies and marks the target cable through the collaborative work of flexible current clamps and signal transmission clamps'√/×'To avoid sawing accidents. This feature significantly reduces the round-trip calibration time for engineering personnel and improves construction efficiency.

Fault location diagnosis

By combining the step voltage method and acoustic magnetic synchronization technology, the instrument can accurately locate the grounding fault point of buried cables. By analyzing the reflected waveform and impedance changes, high impedance faults, low impedance faults, and flashover faults can be distinguished, providing maintenance personnel with clear fault types and location information and shortening repair time.
