Problems solved by technology

[0004] However, the essence of the early warning application is that the tunnel environment has undergone major changes, such as tunnel leakage, lining cracking, lining corrosion, etc.
In such a case, although the alarm can be issued before the accident occurs in the tunnel, due to the great changes in the environment, the probability of the tunnel accident is still relatively high, and it may still cause relatively large losses.

Embodiment 1

[0047] Such as figure 1 As shown, a tunnel monitoring entity risk early warning assessment model, including acquisition unit, transmission unit, input unit, crawling unit, storage unit, analysis unit and early warning unit. Among them, the crawling unit, the storage unit and the analysis unit are integrated with the server, and the input unit and the early warning unit are integrated at the management end.

[0048] The acquisition unit is used to collect geological data and environmental information inside and outside the tunnel; the transmission unit is used to upload the information data collected by the acquisition unit to the analysis unit according to the preset frequency; the preset frequency of uploading data by the transmission unit is 2-50min / Time, in the present embodiment, be 5min / time.

[0049] The input unit is used to input temporary impact information, which includes the location, intensity and duration of temporary construction. The crawling unit is used to...

Embodiment 2

[0054] The difference of Embodiment 1 is that in this embodiment, there are multiple tunnels, and each tunnel has its own collection unit and transmission unit, and each transmission unit has a unique number; geographic location. The acquisition unit includes a shock sensor, a camera and a pickup.

[0055] When the detection value of the vibration sensor of a certain tunnel exceeds the preset value, the corresponding transmission unit sends an abnormal vibration signal to the server and communicates with the server in real time; The transmission unit of the tunnel within the set distance sends an emergency signal; the transmission unit is also used for real-time communication with the server after receiving the emergency signal;

[0056] After the server receives the abnormal vibration signal, if the feedback data of the adjacent tunnel vibration sensor is abnormal within the preset time, the server will analyze the earthquake situation and analyze the disaster situation base...

Abstract

The invention belongs to the technical field of tunnel monitoring, and particularly relates to a tunnel monitoring entity risk early warning evaluation model which comprises an acquisition unit, a transmission unit, an input unit, a crawling unit, a storage unit and an analysis unit. The acquisition unit is used for acquiring geological data and environment information inside and outside a tunnel; the transmission unit is used for uploading the information data acquired by the acquisition unit to the analysis unit according to a preset frequency; the input unit is used for inputting temporary influence information; the crawling unit is used for acquiring meteorological information from a preset channel; a BIM model of a tunnel is stored in the storage unit; the analysis unit is used for predicting whether the risk of a tunnel accident exists or not according to the environmental data, geological data, temporary influence information and meteorological information inside and outside the tunnel; if yes, the analysis unit combines the BIM model of the tunnel to generate an accident simulation diagram. According to the method, the occurrence probability of tunnel accidents can be effectively reduced, and the situation that large losses are caused by the tunnel accidents is reduced.

Description

technical field [0001] The invention belongs to the technical field of tunnel monitoring, and in particular relates to a risk early warning evaluation model of a tunnel monitoring entity. Background technique [0002] Tunnel is a kind of traffic road dug through the mountain, and it is a form of human use of the inner space of the mountain. Reasonable development of tunnels can provide great convenience for people's travel. However, once a safety accident occurs and is not handled properly, it will cause very serious consequences. [0003] Therefore, it is necessary to detect the state of the tunnel. For example, the Chinese invention with the publication number CN107907545A discloses a tunnel rapid detection system and its control method. The image acquisition module is used to collect images of cracks in the tunnel lining in a large area and in all directions. In the machine, use image enhancement technology to improve the clarity and resolution of crack images, use imag...
