The invention relates to the technical field of parking lot lighting systems, in particular to a parking lot underground garage lamp control system which a light illumination module, an intelligent induction module and an early warning module. The light illumination module, the intelligent induction module and the early warning module are operated based on a master controller. Through cooperation of the light illumination module, the intelligent induction module and the early warning module, avoidance of pedestrians and driving and automatic compensation of illumination light can be realized. Meanwhile, aiming at special events such as water leakage, earthquakes and fire, sound prompt and light guide can be provided for vehicles and pedestrians in time. Light intensity, pedestrian signals, driving signals, vibration, smoke and ground accumulated water data information monitored by the intelligent sensing module are fed back to the master controller, the master controller formulates reasonable acousto-optic prompts according to needs, vehicles and pedestrians can avoid coming vehicles, flood, fire disasters and earthquakes in time, and a driver can quickly find a parking space when needing to park.
