Embodiment

[0027] see figure 1 , a dynamic single-mode vehicle type identification method, comprising the steps of: generating an alternating magnetic field after the ground induction coil sensor is powered on and preparing for data collection S11; the vehicle chassis absorbs the alternating magnetic field energy in S11 to generate a change in the inductance of the coil loop and Collect vehicle data S12; the inductance change data is transmitted to the CPU S13 together with other vehicle data after signal selection and signal shaping; the CPU analyzes the data to determine the vehicle type S14.

[0028] There are more than two ground coil sensors in the present invention.

[0029] The alternating magnetic field in S11 of the present invention is 60-300KHZ.

[0030] The vehicle data parameters in S12 of the present invention are vehicle speed, vehicle length, chassis and combinations thereof.

[0031] The present invention also provides a device for realizing a vehicle type identificati...

Abstract

The invention discloses a dynamic single-mode vehicle type identifying method. The method is characterized by comprising the following steps: a, an induction coil sensor after being charged with electricity generates an alternating magnetic field and prepares for collecting data; b, after energy of the alternating magnetic field in the step a is absorbed by a vehicle chassis, change of the inductance value of a coil loop is caused, and the vehicle data are collected; c, the change data of the induction value in the step b are processed through signal selecting and signal shaping and then transmitted to a CPU with the other vehicle data; d, the CPU analyzes the data and determines vehicle types. When the method is used for identifying the vehicle types, the system processes the various collected characteristic data through a CPU vehicle type data model, and then obtains the identification result, when the unusual vehicle types are met, the data model learns again with the unusual vehicle type data as samples, and the identification accuracy of the system is greatly improved through constant self-learning and self-identifying process.

Description

technical field [0001] The invention relates to a vehicle identification device, in particular to a method and a device for identifying a vehicle type in a dynamic single mode. Background technique [0002] With the rapid development of economy and society, the number of people owning cars has increased year by year, and many problems about vehicle management have emerged. For example, due to the rapid increase in the number of various vehicles, various vehicles do not follow the prescribed routes and disturb the people from time to time, resulting in disordered traffic order and inconvenient travel for the masses. Identifying vehicles by manpower to regulate the non-standard use of various vehicles is not only a waste of time, but also inefficient, far from meeting social needs, so people try to realize automatic identification of vehicle types through technology. The automatic identification of vehicle types is a confusing technical problem. Over the years, scientific and...
