High and Low Speed Dynamic Highway Supervisory Network System
主要由高速动态称重子系统、低速高精度动静态称重子系统、车牌识别子系统、车辆指示子系统和计算机管理子系统以及CCTV监控系统组成。 The high and low speed dynamic highway governance monitoring network system is mainly composed of high speed dynamic weighing subsystem, low speed high precision dynamic and static weighing subsystem, license plate recognition subsystem, vehicle instruction subsystem and computer management subsystem, and CCTV monitoring system. The basic detection process of the system is: automatic pre-inspection-low-speed precision inspection-re-inspection after unloading. The system can detect the traffic, axle type, axle (group) weight, and total weight of vehicles passing at the speed of the main road at the speed of 5 ~ 200km / h Parameters such as speed and speed can quickly identify overweight vehicles and can automatically guide suspicious overweight vehicles, and prompt overweight suspicious vehicles to enter the front detection station for fine (re) inspection and weighing.
The high and low speed dynamic highway governance monitoring network system implements a long-term mechanism for governance management, which can guide and promote the standardization of construction of inspection sites, permanent facilities, institutionalization of operations, sophisticated equipment, and network integration of governance management information systems , Data standardization, information sharing, and standardized management.
High and low speed dynamic highway governance monitoring network system is used to control overloaded vehicles on high-grade highways. In order to achieve this purpose, all vehicles must be unrestrictedly detected on the main line, and overloaded vehicles must be selected and released through the vehicle instruction system. Guide the information, guide the vehicle away from the main line and enter the law enforcement area of the inspection station, and accurately weigh and process it.
High-speed dynamic weighing system
The high-speed dynamic weighing system (WIM) is mainly used to obtain the load information of vehicles at high speed without affecting normal traffic, and to select overloaded vehicles according to the set limits, and control the vehicle guidance system to guide the vehicles to leave the main line.
Because the high-speed system is located on the main line and the vehicle is in a complicated state, this subsystem can effectively monitor and control various complex situations such as crossovers and pressure lines.
Vehicle indication system
The vehicle instruction system mainly refers to the information instruction, which is based on the control of the high-speed dynamic weighing system and manual control, and sends guidance information to the vehicle to guide the vehicle to leave the main line and enter the detection station.
The system can be designed differently according to the specific situation, and in some cases can be replaced manually.
Low-speed high-precision dynamic and static weighing system
Low-speed high-precision dynamic and static weighing system is a key subsystem in the entire system. Due to the complex situation of vehicles passing the pre-inspection system on the main line, there are many factors that affect weighing accuracy. According to this, there must be sufficient accurate weighing accuracy.
The CCTV system is designed to monitor the entire process of overloaded and illegal vehicles. Because the entire system is usually distributed in a relatively large range, in order to effectively control overloaded and illegal vehicles, this subsystem plays an important role.
High-speed weighing and data communication Low-speed weighing and data communication High-speed dynamic weighing section real-time tracking of vehicles, escape alarm license plate identification data and vehicle pictures corresponding to high-speed weighing data image capture and low-speed weighing data corresponding to over-limit vehicle license plates Display of exterior pictures and related data Automatically browse, process, and observe all vehicle data and images of pre-selected over-limit vehicles in the main lane. Low-speed review of pre-selected over-limit vehicles. Accurate display of over-limit tonnage can be uploaded via the wired network. The superior administrative office provides statistics, classification, and information storage of highway traffic flow, and provides a real-time, regular transmission interface
