More specifically, the present invention detects vehicle information by calculating a troller according to the wheel grounding position of the vehicle and calculating the tread and using the troller as a variable of the vehicle so as to obtain higher vehicle class classification accuracy. It's about the system.

현재 교통 및 도로관련 계획. 설계, 유지관리를 위한 기본자료를 수집하기 위해 전국적으로 도로 교통량 조사를 수행하고 있다. 그리고 효율적인 교통량 조사 수행을 위해 일반국도 상에는 약 440대의 상시 교통량 조사장비를 설치, 운영하고 있으며, 한국도로공사에서는 고속국도에 약 75대의 매설식 교통량 검지기를 설치, 운영하고 있는 실정이다. 상시 교통량 조사장비의 가장 중요한 구성요소는 주행하는 차량을 검지할 수 있는 센서장치이다. Current traffic and road plans. Road traffic surveys are conducted nationwide to collect basic data for design and maintenance. In order to conduct an efficient traffic survey, approximately 440 regular traffic survey equipment is installed and operated on the national highway, and the Korea Highway Corporation has installed and operated about 75 buried traffic detectors on the high-speed national highway. The most important component of the continuous traffic survey equipment is a sensor device that can detect the vehicle driving.

이를 위한 현재 AVC, WIM장비의 경우 루프(loof)센서에 피에조(piezo)센서 1개 혹은 2개를 평행하게 설치하여 주행중인 차량의 차량길이, 축의 개수, 축간거리를 산출하여 차종분류, 속도파악, 점유시간, 차량의 축별 무게 등을 산출하고 있는 실정이다.In the case of AVC and WIM equipment for this purpose, one or two piezo sensors are installed in parallel on the loop sensor to calculate the vehicle length, the number of axes, and the distance between the vehicles to calculate the vehicle classification and speed. , The occupancy time, and the weight of each vehicle axis are calculated.

도5는 본 발명에 따른 차량의 윤거 산출에 의한 차량정보 검출 시스템이 적용된 차량정보 검출 시스템을 개략적으로 나타낸 구성도이다. 도면에 나타낸 바와 같이, 본 발명에 따른 차량의 윤거 산출에 의한 차량정보 검출 시스템(200)을 차로에 매설하고, 이를 구현하기 위한 장비부는 루프검출장치, 신호증폭장치, 통신장치, 비상전원 및 충전장치, 전원공급장치, A/D변환 및 연산장치, 중앙처리장치, 및 자료저장장치를 포함한다. 5 is a block diagram schematically illustrating a vehicle information detection system to which a vehicle information detection system based on calculation of vehicle lease according to the present invention is applied. As shown in the figure, the vehicle information detection system 200 by embedding the vehicle according to the present invention buried in the lane, and the equipment for implementing this, loop detection device, signal amplifier, communication device, emergency power and charging Devices, power supplies, A / D conversion and computing units, central processing units, and data storage units.

보다 구체적으로, 차량의 윤거 산출에 의한 차량정보 검출 시스템(200) 중 루푸센서는 센서로서 사용하기 적합한 케이블을 사용하며 사각형(또는 원형)으로 회전하여 설치 후 전류를 흘려준다. 유도코일에 의해 발생되는 인덕턴스의 변화 값을 검출하기 위함으로 도로에 매설시 차량(금속물체)주행으로 인해 인덕턴스가 변화 하는 현상을 검출하여 차량의 존재유무를 확인한다.More specifically, the loop sensor in the vehicle information detection system 200 by calculating the vehicle's lubrication uses a cable suitable for use as a sensor and rotates in a square (or circular) to flow a current after installation. In order to detect the change in inductance caused by the induction coil, the presence of the vehicle is checked by detecting the phenomenon that the inductance changes when the vehicle (metal object) is driven on the road.

그리고 피에조센서는 쿼츠 또는 세라믹 소재로 만들어진 센서는 물리적인 압축시 발생되는 압전현상을 이용하여 검출되는 원리로써 빠른 응답특성 때문에 고속으로 주행하는 차량의 검출에 용이하며 가해지는 힘에 비례하는 출력으로 무게 검출에도 응용할 수 있다. 1개의 피에조센서는 평행하게 다른 한 피에조 센서는 사각으로 설치하게 된다.Piezo sensor is a sensor made of quartz or ceramic material that is detected by using piezoelectric phenomena generated during physical compression.It is easy to detect a vehicle traveling at high speed because of its fast response characteristic, and its output is proportional to the applied force. It can also be applied to detection. One piezo sensor is installed in parallel and the other piezo sensor is installed in a square.

다음으로, 장비부 중 루프검출장치는 차량이 해당 루프를 통과할 때 발생되는 인덕턴스변화를 이용 On/Off 시그널의 형태로 출력하여 차량의 존재유무 및 루프를 진입 후 벗어날 때까지의 신호로 지속하여 보내진다. 그리고 신호증폭장치는 피에조센서에서 발생되는 신호는 압전현상으로 그 신호가 매우 미약하다. 따라서 이 신호는 별도의 증폭장치가 필요하다. 신호 증폭 시에는 신호에 포함되어있는 잡음(Noise)도 함께 증폭됨으로 증폭 시에는 필터 등으로 이용하여 순수 신호만을 증폭하여야 한다. 또한 A/D변환 및 연산장치는 루프센서 및 피에조센서에서 검출된 신호를 바탕으로 연산처리과정을 거친 후 차량의 각종 파라미터(속도, 중량, 거리, 제원 등)를 산출한다.Next, the loop detection device of the equipment part outputs in the form of an on / off signal using the inductance change generated when the vehicle passes the loop, and continues as a signal until the vehicle exits and exits the vehicle after entering the loop. Is sent. In the signal amplifier, the signal generated by the piezo sensor is a piezoelectric phenomenon, and the signal is very weak. Therefore, this signal requires a separate amplifier. When amplifying a signal, the noise included in the signal is also amplified. Therefore, only a pure signal should be amplified using a filter. In addition, the A / D conversion and calculation device calculates various parameters (speed, weight, distance, specification, etc.) of the vehicle after undergoing a calculation process based on the signals detected by the loop sensor and the piezo sensor.

그리고, 중앙처리장치는 마이크로프로세서 등으로 구성된 장치는 연산처리장치를 통해 수집된 데이터를 바탕으로 통계처리를 수행한다. 또한 필요시 데이터 일부를 저장 및 보관할 수 있고, 자료저장장치는 중앙처리장치에서 최종 처리된 통계데이터를 보관하는 장치이며 설계에 따라 저장 용량을 결정할 수 있다.In addition, the central processing unit includes a microprocessor or the like performs statistical processing based on the data collected through the processing unit. In addition, some data can be stored and stored when needed, and the data storage device is a device for storing the final processed statistical data in the central processing unit, and the storage capacity can be determined according to the design.

상기 전원공급장치는 여러 가지 장치들이 작업을 수행하는데 필요한 안정적인 전원을 공급하는 장치이며 필요에따라 AC 100~220V , DC 12 ~ 24V를 선택하여 사용할 수 있고, 비상전원 및 충전장치는 장비에서 사용하고 있는 주전원이 차단되었을때 일정시간동안 시스템을 유지하기 위하여 준비해두는 비상전원 장치이며 ㅂ베터리로 구성된다. 다음으로, 통신장치는 장비에 저장된 데이터 및 파라미터등을 다운로드하거나 업로드, 다른 장치로 송신 또는 수신하기 위한 통신장치이다. The power supply is a device that supplies stable power required for various devices to perform work, and can be selected and used according to the needs of AC 100-220V, DC 12-24V, and emergency power and charging devices are used in the equipment. It is an emergency power supply which is prepared to maintain the system for a certain period of time when the main power is cut off. Next, the communication device is a communication device for downloading or uploading data, parameters, and the like stored in the equipment, and for transmitting or receiving to another device.

이와 같이 이루어짐에 따라, 도로현장에서 센서를 통한 교통량, 속도, 점유시간, 차종별 교통량의 수집이 가능하며 개별 차량에 대한 속도, 자료유시간 자료 등을 산출하고 또한 30초, 1분, 5분, 10분, 1시간등 사용자의 요구에 따라서 통계처리한 자료를 메모리에 저장하고 통신모듈을 통하여 자료수집센터로 전송할 수 있 는 기능을 보유할 수 있게 된다. In this way, it is possible to collect traffic volume, speed, occupancy time and traffic volume by sensor at the road site, calculate speed, data time data for individual vehicles, and calculate 30 seconds, 1 minute, 5 minutes, According to the user's request, such as 10 minutes, 1 hour, the statistical processing data can be stored in the memory and transferred to the data collection center through the communication module.
