The invention relates to a tunnel safety early warning system device based on an inductance method. A tunnel safety early warning system device based on an inductance method is characterized in that measuring nodes are arranged from a tunnel entrance to a tunnel exit according to 100-meter segments along a lane, and n segments are arranged after rounding; a left rear ground sensing coil is embedded at a left lane of all measuring nodes, a left front ground sensing coil is embedded at a position 5 meters right ahead of the left rear ground sensing coil, an MCU minimum system is arranged on the left side of the lane where the left rear ground sensing coil is located, an LED electronic screen is arranged at a position 25 meters in front of the left rear ground sensing coil and on the left side of a tunnel, and a left license plate snapshot camera is installed above the LED electronic screen. The left rear ground induction coil and the left front ground induction coil are electrically connected with the MCU minimum system through a coil controller; the beneficial effects of the invention are that the installation of the ground induction coil does not affect the driving of vehicles, and the ground induction coil is low in price, strong in anti-electromagnetic interference, reliable in work, capable of working stably for a long time without maintenance, low in use cost, and especially suitable for being used in tunnels.
