The invention provides a roadside area-variable 
parking space management system with an advertising function and an operation method thereof. The 
system comprises a 
parking area, an on-site sensing execution end, a 
network communication layer and a background management center; the on-site sensing execution end comprises an MCU, a power source module, an earth 
induction coil, an earth induction device, a 
smart camera, a 
laser ranging module, a 
laser scanning module, a voice speaker, an 
LED display screen, an LED beam lamp strip, a fee charging module, a 
signal transmit-receive antenna and an advertising module; the 
network communication layer communicates based on an NB-IoT network; and the background management center is provided with an 
Internet of Things service system. According to theroadside area-variable 
parking space management system with the advertising function and the operation method thereof of the invention, a 
parking area is automatically planned according to the size of a vehicle, and the number of parked vehicles can be increased; fee charging is based on two 
modes, namely, reservation locking and model size, so that the fee charging is fair and reasonable; an advertising projection lamp is used to project an advertisement to the body of a vehicle or the ground, so that urban roadside parking spaces can be managed automatically in a standardized manner, and the 
system meets the management requirements of smart cities in the new era.
