Technical Field

[0001] This invention relates to an underground pipeline network monitoring system, belonging to the fields of communication technology and underground pipeline network management technology. Background Technology

[0002] Currently, underground pipeline systems require regular monitoring to detect potential safety hazards. However, due to their deep burial, direct observation by staff is difficult. Wireless communication signals suffer from signal quality issues due to ground obstruction, severely impacting the quality and efficiency of monitoring. Furthermore, the wide coverage and complex structure of underground pipeline systems mean that traditional manual inspection methods and equipment are labor-intensive and inefficient.

[0003] Meanwhile, the current detection systems or equipment are relatively simple in structure, often only meeting the needs of monitoring the operation of underground pipe network systems of specific structural types. They also cannot keep pace with the development of underground pipe network systems, resulting in relatively poor flexibility and versatility in the use of current underground pipe network monitoring systems.

On the other hand, the monitoring data is comprehensive and the data communication capability is strong, which effectively overcomes the shortcomings of traditional underground pipe network systems, such as poor communication signal caused by the obstruction of the underground strata, making it difficult to effectively monitor underground pipe networks and the difficulty of monitoring data collection and communication.
