[0002] At present, tunnels, as an important underground transportation and infrastructure, face many challenges in their management and maintenance. With the acceleration of urbanization and the growth of transportation demand, the construction and use of tunnels are increasing. However, the uniqueness of the tunnel environment has brought a series of technical challenges, especially in wireless communication and structural health monitoring.

[0003] In tunnel environments, due to the complexity of geological structures and the influence of building materials, wireless signal transmission is often severely attenuated and interfered. Traditional wireless communication technologies (such as Wi-Fi, cellular networks, etc.) often perform poorly inside tunnels, resulting in insufficient or intermittent signal coverage, inaccurate location information of staff and equipment, and affecting the effectiveness of emergency response and daily management. The structural health of the tunnel directly affects its safety and service life, but due to the complex internal environment of the tunnel, traditional monitoring methods (such as manual inspections, fixed sensors, etc.) are difficult to achieve real-time and comprehensive monitoring. Existing tunnel management systems are often independent of each other and lack a unified data platform and management mechanism. Managers need to manually summarize data from different systems, which is inefficient and prone to information omissions or errors.

The signals in the 380-470MHz frequency band have good propagation characteristics, can cover a larger geographical range, and are less interfered with, which helps to improve the reliability and stability of communication; the main anti-interference communication network adopts the 915-920MHz frequency band. The 915MHz frequency band is relatively clean and is less interfered with by other radio services, which helps to ensure the stability and reliability of communication; the slave anti-interference communication network adopts the 868-877MHz frequency band; 868MHz~877MHz belongs to the low frequency band, and the low frequency band signals have good penetration ability and a longer propagation distance, which is suitable for occasions requiring long-distance communication or penetration of obstacles (such as buildings, trees, etc.).

[0080] Preferably, Figure 5 As shown, the interference detection unit, the interference signal judgment process is:

[0081] Receive signal data and perform pre-processing to convert it into an intermediate frequency signal;

[0084] When the number of interference values ​​is greater than the preset value, it is determined as an abnormal signal, otherwise it is a normal signal;

[0085] And perform a preset number of detections and judgments within a preset time. If the judgment results are all abnormal signals, it is determined to be interfered;

[0086] Generate and send signal abnormality information to the network switching unit, otherwise continue to detect and judge.

[0087] Preferably, the method for obtaining the envelope value is: initialize the sliding window length, traverse the intermediate frequency signal, for each sampling point, slide the window forward and backward, calculate the absolute value of the signal in the window, and take the maximum value as the envelope value of the point, and take the envelope value less than the set threshold from the forward sliding window envelope value and the backward sliding window envelope value as the final envelope value.

[0094] Preferably, the interference detection unit of the present invention can avoid unnecessary network switching caused by short-term interference or signal fluctuations by performing multiple detection and judgment within a preset time.

Based on the comparison results, the intelligent routing algorithm can dynamically adjust the data transmission path. When a path is detected to have high delay or high packet loss rate, the intelligent routing algorithm will recalculate and select a better path to transmit data, that is, select the optimal communication network and generate a corresponding network switching signal.

[0097] Preferably, the intelligent routing algorithm dynamically selects the best path according to the network status and data transmission requirements, which can effectively improve the stability and efficiency of signal transmission in the tunnel.
