Abstract

The application relates to the technical field of tunnel construction supervision, and in particular to a tunnel construction supervision alarm system and method. The system includes a monitoring module, an alarm module, a fan module, a prediction module, an air volume detection module and a control module, and the prediction module is used for real-time acquisition. Calculate the difference between the intake air volume and the exhaust air volume of the fan module, and then calculate the maximum oxygen content required for breathing by the construction workers in the tunnel and the air volume required to remove the exhaust gas of the internal combustion engine as the subtrahend, and simulate the actual intake air volume based on the calculation results. to determine whether the air volume value detected by the air volume detection module is below the characteristic curve of the actual air intake volume; when the air volume value detected by the air volume detection module is below the characteristic curve of the actual air intake volume, the control module receives the output signal of the prediction module , the alarm module responds to the control module to give an alarm. The problem of low accuracy of the existing alarm results is solved. The present application has the effect of improving the accuracy.

Description

technical field [0001] The invention relates to the technical field of tunnel construction supervision, in particular to a tunnel construction supervision alarm system and method. Background technique [0002] Construction supervision is very important to the safety of tunnel engineering projects. In particular, in the process of tunnel construction, blasting operations are frequent, and a slight accident may cause explosion and injury accidents. [0003] A large amount of dust will be generated during blasting, which will cause dust in the surrounding environment, and the construction equipment will be easily damaged; more seriously, the dust will accumulate static electricity due to mutual collision and friction during the production process. When it reaches a certain value, it will appear. Electrostatic discharge can cause fire and explosion accidents. [0004] At present, the concentration of dust is generally monitored by a dust detector. When the dust detector senses...
