The invention aims at providing a wireless geomagnetic vehicle flow terminal detector. The detector is characterized in that the detector is composed of a main detector body, a magnetoresistive sensor, an amplifier, an analog-to-digital conversion device, a CPU wireless processing module, a single-chip microcomputer, a battery, and a wireless signal transmitting module. The terminal detector is a product widely applied to an urban automotive vehicle detection system and the main principle is that a wireless geomagnetic vehicle detection system is involved, thereby detecting an operating state of a motor vehicle involved in the traffic. After received data are processed by an embedded type micro processor, the processed data are transmitted to an urban center communication server or a field signal controller, thereby providing traffic basic data of time headways, occupied time, vehicle velocities, and vehicle flows and the like of lanes of roads for users. The terminal detector has advantages of small size, simple and convenient installation, excellent anti-interference capability, high adaptability, eliminated environment influence and mutual interference, maintenance-free property, low cost, and low power consumption.
