Integration monitoring system and method of tunnel construction and operation phase

The invention discloses an integration monitoring system of tunnel construction and an operation phase. The integration monitoring system of the tunnel construction and the operation phase comprises multiple sensors, multiple automatic collecting devices, a data transmission system, a protocol converter and a monitoring computer, wherein the multiple sensors are arranged in different section surfaces of the tunnel construction and a completed initial stage, the multiple automatic collecting devices are connected in series through buses, and a signal output end of each sensor is connected with a signal output end of a corresponding automatic collecting device, the automatic collecting devices are in communication connection with the protocol converter through the data transmission system, and a data port of the protocol converter is connected with a data port of the monitoring computer. The invention further discloses a method which is used for the integration monitoring system of the tunnel construction and the operation phase. According to the integration monitoring system and the method of the tunnel construction and the operation phase, a long-term monitoring component with good durability is arranged, and a long-term monitoring network is formed, and whole process monitoring to structural mechanics behavior characteristics in the full-life range of a tunnel from construction to tour finish is carried out.
