The invention relates to speed limit monitoring device. An input port of a single-chip microcomputer is connected with a speed sensor, a timer and a GPS module, an output port of the single-chip microcomputer is connected with an alarm and a wireless signal transceiver, wherein the wireless signal transceiver sends vehicle overspeed data to a monitoring center server through a wireless network; and the monitoring center server sends alarm information to wireless signal transceivers of other vehicles and performs reminding through a vehicle-mounted alarm unit, distance between other vehicles that receive the alarm information and a monitored vehicle does not exceed five kilometers, and the alarm information includes the model, the license plate, the position and current speed of the vehicle. The monitoring device provided by the invention can send the vehicle overspeed information to the monitoring center, and the monitoring center can send the alarm information to the vehicles around the overspeed vehicle, so that the surrounding vehicles can evade in advance, thereby avoiding occurrence of a traffic accident.
