Experts’ Diagnoses for Metro Tunnel
In traditional Chinese medicine (TCM), the doctor can tell the diagnosis after using the four diagnostic methods including observing, listening, asking, and feeling the pulse of the patient. Now the question is how can one judge and tell that if the tunnel structure is in an ill condition or not? The tunnel experts have developed the sensitive and accurate sensors that can perceive the tunnel diseases. Through those temperature, humidity, acceleration, crack, deformation, and water leakage sensors, the values of all types of distress can be measured. The wireless sensor network (WSN) installed on the tunnel structure can collect and transmit the data, so that the distress information can be obtained in time.
