Automobile overload non-stop detection system and detection method based on RFID

Abstract

The invention provides an automobile overload non-stop detection system and detection method based on RFID. The system includes a piezoelectric cable sensor, two groups of infrared grating instruments, an RFID reader, an RFID label, a computer, a DSP processor, a signal amplification circuit, a timer, and an LED display screen. A weigh-in-motion system is composed of the piezoelectric cable sensor, the signal amplification circuit, and the DSP processor, the dynamic weighing system is connected with the computer, the timer is connected with the infrared grating instruments, the infrared grating instruments are connected with the piezoelectric sensor, the RFID reader is connected with the computer, the RFID label is arranged on an automobile, and the computer is connected with the LED display screen. The weigh-in-motion system measures the weight signal during the automobile driving process and performs data processing; the timer records the automobile driving time; and the infrared grating instruments eliminate vehicle following phenomenon and are taken as the switch of the weigh-in-motion system. The system has the characteristics of high measurement precision, less damage to the pavement, and high adaptability.

Description

technical field [0001] The invention relates to a traffic intelligent control system for road vehicles, in particular to an RFID-based vehicle overload non-stop detection system and detection method. Background technique [0002] With the rapid development of the national economy, my country's traffic has also made great progress, the highway mileage is increasing, followed by the increasing traffic flow, resulting in traffic congestion, especially overloaded vehicles on the existing road surface Both bridges and bridges have brought greater damage, which in turn has brought huge harm to driving safety, and has become a "chronic disease" that endangers the sustainable development of road traffic. According to the "Administrative Measures for Highway Overrun Detection Stations" (Decree No. 7, 2011 of the Ministry of Transport of the People's Republic of China), the design and research of the non-stop overload detection system is carried out, mainly to realize the non-stop of t...

Problems solved by technology

[0007] The purpose of the present invention is to provide a detection system and detection method based on RFID-based vehicle overloading and non-stopping, which solves the problem that the existing system cannot effectively eliminate the phenomenon of following the car, and cannot identify the bicycle and trailer; The accuracy of the weighing system is greatly disturbed by the vibration of the vehicle, and it is impossible to collect the loading source information of the loading vehicle.
