The invention discloses a traffic information monitoring signal acquiring device based on GMI sensors and a detecting method, relates to a traffic information monitoring signal acquiring device and a detecting method and belongs to the technical field of sensors and application. The signal acquiring device comprises a signal acquiring module, a data processing module, a radio frequency module and a power supply module. The data processing module is used for reading the real-time state of each GMI sensor, magnetic field variation information sent by a filter amplifier is acquired, data processing is performed, road automobile flow, vehicle speed and vehicle body information are calculated according to obtained information, the vehicle driving condition is judged, and the information is sent to the radio frequency module so that a road can be monitored in real time. The invention further discloses the detecting method achieved through the traffic information monitoring signal acquiring device based on the GMI sensors. The traffic information monitoring signal acquiring device based on the GMI sensors and the detecting method have the following advantages that measured information is much; electricity in use is saved; damage to a road surface is small, and cost is low; under the condition that calculating precision is guaranteed, the computational burden is little, and system real-time performance is guaranteed.
