The invention provides an over-speed vehicle detecting method and system, and aims to accurately detect whether vehicles on an integrated road exceed the speed limit or not around the clock. The system comprises electronic car license plates, at least three interconnected and synchronous base stations and a positioning server, the electronic car license plates are attached to the vehicles and used for transmitting ultra-wideband pulse signals to the base stations, the base stations are positioned road sections with speed to be measured and used for receiving the ultra-wideband pulse signals transmitted by the electronic car license plates and transmitting moments receiving the ultra-wideband pulse signals to the positioning server, and the positioning server is used for positioning the vehicles with the attached electronic car license plates according to positioning algorithms and the moments of the base stations receiving the ultra-wideband pulse signals and judging whether the vehicles with the attached electronic car license plates exceed the speed limit or not according to positioning results and the limit speed of the vehicles on the road sections with speed to be measured. The speed of the vehicles on the integrated road can be monitored, real over-speed vehicle detection is achieved, the system is high in positioning accuracy and can accurately detect whether the vehicles exceed the speed limit or not, and detecting accuracy is improved.
