Abstract

The invention discloses a wireless sensory detection device and a wireless sensory detection method for a tunnel environment, relates to a detection device and a detection method for the tunnel environment, and aims at solving the problems that a conventional detection device and a conventional detection method have the disadvantages that an instrument is cumbersome, the mounting is complicated and the cost is high. The wireless sensory detection device for the tunnel environment consists of N wireless sensory transmission nodes and a wireless information collection node. The wireless sensory detection method for the tunnel environment comprises the following steps of: 1, giving a fixed-frequency pumping signal fL to a sensor to begin sweeping a frequency by using a first singlechip processing unit in the wireless sensory transmission nodes; 2, judging whether the sensor generates resonance vibration or not, and if yes, executing a step 4; 3, the sum of the fL and delta, judging that the sum of the fL and the delta is less than fm; 4, sending a detected signal to the wireless information collection node through an electromagnetic wave by using a detection circuit; and 5, receiving information for processing by using the wireless information collection node, and alarming if an environmental parameter is judged to be a dangerous value. The wireless sensory detection device and the wireless sensory detection method are applicable to the detection device and the detection method for the tunnel environment.

Description

technical field [0001] The invention relates to a tunnel environment detection device and method. Background technique [0002] Road transportation is the main artery of the national economy, and transportation safety is the top priority of road transportation. However, due to the complex terrain of our country, the tunnel in the road section is an important part of the road. The safety of the tunnel has become an important item in transportation safety, that is to say, the safety of the tunnel environment is related to the safety of transportation, and even human life is a big issue. [0003] At present, the detection of the tunnel environment in tunnel engineering generally uses wired strain gauges or string vibration detection devices to monitor the tunnel environment. However, the detection device and method have the problems of heavy equipment, complicated installation, and high cost. Especially during the construction process, the wired monitoring equipment is easily...
