Rolling sensing device and signal processing method thereof

Abstract

The invention relates to the field of intelligent traffic, in particular to a rolling sensing device and a signal processing method thereof. The rolling sensing device comprises a sensing band composed of a plurality of sensors connected in parallel, a signal processing module and a micro-control unit (MCU); the sensing band, the signal processing module and the MCU are electrically connected; thesensing band processes a collected signal and sends the signal to the signal processing module; after receiving the signal, the signal processing module processes the signal and sends the signal to the MCU; and the exterior of the sensing band is provided with a protective shell covering the sensing band. According to the device, the plurality of rolling sensors are connected in parallel, so thatthe problem of low identification precision in the prior art is solved; the protective shell is arranged on the outer layer of the sensing band, so that ground mounting can be achieved, and the problem of difficulty in laying in the prior art is solved; and the laying cost is low, so that large-area laying is facilitated.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a rolling sensor device and a signal processing method thereof. Background technique [0002] With the continuous expansion of urban areas in various countries and the escalation of traffic congestion, the construction of smart transportation has become an indispensable infrastructure project to relieve traffic pressure, and the foundation and core facilities of smart transportation construction are detection sensors. Commonly used detection sensors are generally piezoelectric films, piezoelectric coaxial sensors, etc., which are mainly used for road traffic flow detection, red light detection, parking space detection, etc. Although piezoelectric films and piezoelectric coaxial cables can monitor very subtle changes, It is generally used for fine detection, but the cost is very high. The high cost makes it impossible to lay these detection sensors on a large sc...
