Intelligent distributed traffic control system

Abstract

The invention discloses an intelligent distributed traffic control system. The system comprises a plurality of vehicle-mounted controllers which send corresponding train position information to a control center; the control center is connected with the intelligent traffic control box through a backbone network interface, receives the train position information and sends the train position information to the system; the intelligent traffic control box is connected with a loudspeaker, a barrier gate and a signal lamp through a special signal machine interface on the barrier gate, reads intersection information and feeds back the intersection information to the control center; and a plurality of interfaces. According to the system, a distributed architecture design is adopted, a dual-redundancy CPU is arranged in the center, the mode that the center CPU is in interface with a vehicle-mounted and center ATS system is adopted, system linkage is simplified, and scattered processing control is changed into centralized processing distribution control. The system is combined with a GPS positioning system, an intersection barrier gate machine and voice alarm equipment, an intersection is opened preferentially for the tramcar, independent release of the tramcar and social vehicles is achieved, and it is guaranteed that the tramcar passes through the level crossing preferentially, safely and efficiently.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to an intelligent distributed traffic control system. Background technique [0002] Traditional railway level crossing traffic control can only solve the problem of blocking pedestrians and vehicles passing by on the current highway, and cannot centralize and coordinate the situation of mixed road rights, that is, the situation where trams and social vehicles share road rights. The efficiency of train operation cannot be improved, and the efficiency of train-ground coordination is low. Separate interface protocols need to be designed between crossings and between crossings and trams. The docking work is cumbersome, the linkage is slow, and it is impossible to set the priority of the right of way separately. [0003] In view of the single traffic control function and complicated interface of the traditional railway level crossing, when used in the crossing control, each cro...

[0002] Traditional railway level crossing traffic control can only solve the problem of blocking pedestrians and vehicles passing by on the current highway, and cannot centralize and coordinate the situation of mixed road rights, that is, the situation where trams and social vehicles share road rights

The efficiency of train operation cannot be improved, and the efficiency of train-ground coordination is low. Separate interface protocols need to be designed between crossings and between crossings and trams. The docking work is cumbersome and the linkage is slow. It is impossible to set the priority of the right of way separately.

[0003] In view of the single traffic control function and complicated interface of the traditional railway level crossing, when used in crossing control, each crossing control box needs to communicate with the tram vehicle system separately, and the interface protocol is designed. The patent of this invention has developed an intelligent distributed traffic control system.
