The invention discloses a large vehicle right turn blind area early warning system based on a coupling ground induction coil, and relates to the technical field of road traffic safety. The large vehicle right turn blind area early warning system comprises a ground induction coil device and an alarm device. The ground induction coil device is arranged on the inner edge of the right turn blind area early warning marking line, and the alarm device is located at the crossing position of a right turn lane and a pedestrian crossing and is connected with the ground induction coil device through a cable; when a pedestrian enters the right turning blind area, the pedestrian cuts the magnetic field generated by the ground induction coil device to generate magnetic flux change, and the alarm device sends out an alarm signal. The ground induction coil device does not need to damage an original road surface, is low in construction difficulty, short in period and easy to universally apply; due to the multi-layer structural form, the damage probability of the ground induction coil device is reduced, the system stability is improved, and the system maintenance cost is reduced; the device is simple in magnetic flux detection, high in precision, low in cost, suitable for various intersections, and suitable for large-area use in medium common cities and underdeveloped areas.
