The invention discloses a system for detecting pedestrian flow by coupling ground induction coils, and relates to the field of pedestrian flow monitoring. The pedestrian flow detection system comprises a ground induction coil device, a trigger device, a detection device and an information processing device. A trigger device is connected with a pedestrian crossing signal lamp, a red lamp is turned on, the ground induction coil device is triggered to enter a working state, the working frequency is increased, a signal lamp waiting area generates a variable-frequency magnetic field harmless to human bodies, and an initial interference value X < initial > of the magnetic field is recorded; a pedestrian enters the signal lamp waiting area; before the detection device detects that a green lamp is turned on, an interference value X < tail > of the magnetic field is turned on; the ground induction coil device enters a sleep standby state; the information processing device records an average interference value X0 of pedestrians on the magnetic field and the number of pedestrians passing through the intersection in the period (N is an integer). The system is low in construction difficulty, short in period, low in maintenance cost and easy to be widely applied to medium common or underdeveloped areas; the system has strong anti-interference performance and strong stability, and is not influenced by severe weather such as rain, snow, heavy fog and the like.
