Problems solved by technology

[0003] At present, there are not many intelligent transportation systems (ITS) that are truly efficient, low-cost, and interactive. The traffic command systems that have been built and are under construction have varying degrees of high cost, inconvenient installation, and difficulties in maintenance and system expansion. , poor real-time performance or poor versatility, and powerful video information traffic command systems cannot perform normal functions under conditions of poor visibility (such as heavy fog, strong wind and sand, or rainy and snowy days), and they do not have the ability to control highways. Real-time intelligent monitoring, anti-rear collision warning and assisted driving functions can be achieved in the whole railway. According to the technical requirements of modern ITS, there is still a big gap

Embodiment 1

[0039] Figure 1 shows the single-lane highway interactive intelligent road stud and its road network information system. It consists of an integrated buried or mounted interactive intelligent road stud (3), a controller (1), and an interconnected communication cable ( 4), the field bus (6) using LonWorks field bus technology, the multi-function on-board card / box (5) on the vehicle (7), and the centralized power supply for each group of interactive smart road studs (3) and controller (1) The solar battery pack (2), the traffic guidance screen / electronic signboard (8) and the central computer (9) are composed, and the interactive smart road studs (3) are arranged on the road (11) at an appropriate distance (25-50 meters). On the road, the multi-function vehicle card / box (5) is placed on the vehicle (7) driving on the road, and the interactive smart road stud (3) communicates directly or indirectly through its embedded wired or wireless data communication device. The data communi...

Embodiment 2

[0046] Figure 4 shows the two-lane interactive intelligent road stud and its road network information system. The difference between it and Embodiment 1 is that the road is a two-lane road in the same direction, and interactive intelligent road studs are arranged on each lane. The multi-function on-board card / box configured on the vehicle is identifiable. The road network information system can identify the source of receiving information or the object of information release on different lanes according to the information coding communication between the road stud and the multi-function on-board card / box. The working process is similar to that of Embodiment 1. In addition to the system functions of Embodiment 1, one-to-one question / answer dialogues can be conducted between the road stud and the multi-function vehicle card / box, and the system can also search and locate the vehicle, etc. .

Embodiment 3

[0048] Figure 5 shows the single-lane railway interactive intelligent road stud and its road network information system, which consists of an integrated road side-mounted interactive intelligent road stud (12), a controller (15), an interconnected communication cable (13), The field bus (14) adopting the LonWorks field bus technology, the multi-functional on-board card / box on the train, the input / output control signal interface module (11), the traffic signal light (16) and the central computer (17) are composed, and the interactive smart road Nails (12) are arranged on one side of the road (18) with an appropriate spacing (200-300 meters), and the controller (15) is provided with two field buses, and the twisted pair is used as the communication transmission medium of the field bus (14). And supply power to the interactive intelligent road stud (12) and I / O module (11), the two field buses are laid in the opposite direction of the railway, and the road section traffic lights (...

Abstract

An interactive smart nails and network information systems, its features is that it is formed by at least by a group of interactive intelligent nails, multifunctional vehicle card / box structure, an interactive smart nails with the appropriate spacing emplaced on the road , road side road or parking place, multifunctional vehicle card / box placed in vehicles, interactive smart nail through its embedded between the wired or wireless data communication devices direct or indirect data communication connectivity, interactive Intelligence nails passing through or near their vehicles at the multi-purpose vehicle card / box and through their respective embedded wireless data communication devices can be single / two-way information and communication. This invention has a variety of functions, high level of intelligence information, reliable performance, lower system costs, the advantages of easy installation, and system maintenance and expansion easy, round-the-clock weather conditions in the application.

Description

technical field [0001] The invention relates to an interactive intelligent road stud and its road network information system. The system can be used as an urban traffic information management system, a monitoring and anti-rear-end collision warning for high-grade highways, a road network information management system, and a monitoring and anti-rear-end collision for railway traffic. Warning and command dispatching and information management system, road intelligent electronic marking and traffic information management system, parking lot management and parking guidance information management system, and intelligent transportation system (ITS) with vehicle auxiliary driving function can also be constructed. Background technique [0002] With the development of the economy and the improvement of people's living standards, the development of land transportation is getting faster and faster, and the number of vehicles is expanding. Urban traffic and highway traffic congestion occ...
