Problems solved by technology

[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.

Embodiment 1

[0027] Example 1, such as figure 1 and figure 2 As shown, the framework of the intelligent distributed traffic control system is:

[0028] (1) Each intelligent traffic signal control box adopts CPU1500 series + distributed I / O module group to realize intersection logic control, and a distributed I / O module group is placed in each intersection control box, and dual-system CPU1513R is placed in the central control room to pass PROFINET communication to the distributed I / O module group, using optical fiber communication.

[0029] (2) CPU1513R uses MODBUS TCP protocol to communicate with the TPS server of the control center through the Ethernet port, collects the location information of all vehicles, and defines it in a network segment.

[0030] (3) The control architecture of dual-system CPU1513R+ distributed I / O module group is adopted, and all relevant intersections are controlled by one CPU. In order to improve the safety and stability of the system, the scheme is designed ...

Embodiment 2

[0042] Example 2, such as image 3 As shown, the intelligent traffic control box includes a box body, a fan arranged on the top of the box body, a limit switch and the lighting in the cabinet suspended from the top of the box body; the middle part of the box body is provided with a mounting plate , a knob box is placed above the mounting plate for manual / automatic control of the intelligent traffic control box;

[0043] The installation board is divided into three parts, the first part is placed with a switching power supply for providing power for the intelligent traffic control box, the second part is placed with a PLC controller, a switch and a relay socketed on the switch, The third part is placed with terminals;

[0044] A power amplifier and an optical fiber terminal box are placed at the bottom of the box body.

[0045]The intelligent traffic signal control box can work reliably under the following environmental conditions:

[0046] (1) The altitude of the installati...

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.
