Abstract
The invention relates to the tunnel excavation technical field, and especially to an anti-deflection system for the tunnel excavation. The anti-deflection system includes a power package, a laser transmitter module, a laser reception module, a filter, a single chip microcomputer, and a control console. The power package provides power for the laser transmitter module. An output end of the laser transmitter module is connected to an input end of the laser reception module. An output end of the laser reception module is connected to an input end of the filter. An output end of the filter is connected to an input end of the single chip microcomputer. An output end of the single chip microcomputer is connected to the control console. The anti-deflection system for the tunnel excavation employs the laser transmitter module and the laser reception module. Because the alignment of the laser is good, the laser is usually used as direction guidance. An excavator can excavate a tunnel in the laser direction, so that the deflection cannot generate during an excavation process. In addition an avalanche photodiode is arranged in the laser transmitter module and may be used for detecting weak light and measuring the distance. The system has simple structure and strong practicality.
