specific Embodiment approach 1

[0021] Specific embodiment one: the real-time remote monitoring system of road traffic load information described in this embodiment is made up of a plurality of data acquisition terminals and a central server, and the plurality of data acquisition terminals realize data transmission through a 3G network and a central server; the data The acquisition terminal includes a 3G data transmission module, an industrial computer, a data acquisition card, a signal amplifier and a pair of dynamic weighing sensors, and the signal output ends of each of the dynamic weighing sensors are respectively connected with two signal input ends of the signal amplification circuit, The serial data output end of the signal amplifying circuit is connected to the analog signal input end of the data acquisition card, and the digital signal output end of the data acquisition card is connected to the serial data bus or the parallel data bus of the industrial computer. There is a module with 3G data transmi...

specific Embodiment approach 2

[0026] Specific embodiment two: The difference between this embodiment and the real-time remote monitoring system for road traffic load information described in specific embodiment one is that each data acquisition terminal also includes a pair of dynamic weighing sensors, and the signal amplification circuit is a multi-channel A signal amplifying circuit, the two signal output ends of the pair of dynamic weighing sensors are respectively connected to the two signal input ends of the signal amplifying circuit.

[0027] The data collection terminal of this embodiment adds a pair of dynamic weighing sensors, and the pair of dynamic weighing sensors and the other pair of dynamic weighing sensors are buried in the same traffic lane, and are respectively located in the two half lanes of the traffic lane, The distance between two dynamic load cells located in the same half lane is 5-7 meters, and all dynamic load cells are arranged parallel to each other. The distance between the ce...

specific Embodiment approach 3

[0035] Specific embodiment three: the difference between this embodiment and the real-time remote monitoring system for road traffic load information described in specific embodiment one or two is that each data acquisition terminal also includes an external weighing display screen, and the external weighing display screen is flat The display data input end of the industrial computer is connected to the display data output end of the industrial computer.

[0036] The external weighing display added in this embodiment can be realized by using LCD or LED display.

Abstract

The invention discloses a real-time remote monitoring system of highway traffic load information, which relates to the technical field of traffic and transportation engineering, and solves the problems that in the traditional highway traffic information acquisition mode, the data acquisition is not timely, the data volume is limited, and the actual traffic load information acquisition is not timely. The real-time remote monitoring system of the highway traffic load information is characterized in that data transmission is realized by multiple data acquisition ends through a 3G (The 3rd Generation) network and a central server; a signal output end of each dynamic weighing sensor in the data acquisition ends is respectively connected with two signal input ends of a signal amplifying circuit, a serial data output end of the signal amplifying circuit is connected with an analog signal input end of a data acquisition card, a digital signal output end of the data acquisition card is connected with a serial data bus or a parallel data bus of an IPC (Industrial Personal Computer), and the IPC is connected with a 3G data transmission module; and a pair of the dynamic weighing sensors is mutually and parallelly embedded at a center position of the same carriage-way. According to the real-time remote monitoring system of the highway traffic load information, disclosed by the invention, the requirement of long-time and real-time monitoring of the highway traffic integrated information can be met.

Description

technical field [0001] The invention relates to the technical field of transportation engineering. Background technique [0002] In the process of expressway construction, use and management in my country for nearly two decades, so far there is no new or expanded expressway that has accumulated long-term, complete, systematic and detailed traffic load and pavement performance after it has been put into use. data, especially traffic information data (traffic load size, quantity and distribution). If the traffic load information is unclear, any judgment on the service condition of the structure will be one-sided. When it comes to the pavement structure, if the magnitude of the load it has endured and will bear and the exact number of times are not clear, then the analysis, evaluation and prediction of the pavement condition will be unreliable, let alone perfect design. Provide a basis for modifying design specifications and determining reasonable maintenance countermeasures. ...
