Problems solved by technology

In the current domestic urban rail transit signal system, manual guarding is generally used to ensure the safe passage of trains at intersections. When a train passes through an intersection, the information exchange between the on-board controller, the operation dispatching center, and the intersection Need to rely on loop and track circuits, and no real-time communication between the three

Embodiment Construction

[0021] The present invention will be further described below in conjunction with embodiment, but protection scope of the present invention is not limited to this:

[0022] combine figure 1 The preferred embodiment is described. The on-board controller is arranged on the tram, the traffic signal controller is arranged at each intersection, and the operation dispatching center coordinates the overall traffic network. The above three facilities are all prior art. The intersection controller is set at each intersection. The intersection controller and the operation dispatching center communicate through the network port using the UDP protocol. The intersection controller and the operation dispatching center communicate through the network port using the UDP protocol. The intersection controller communicates with the traffic signal The controller achieves the control purpose through a set of relay dry contacts.

[0023] The intersection controller is composed of intersection contr...

Abstract

The invention discloses an intersection signal control method for a streetcar. Information interaction among an intersection controller, traffic signal controller, an operation dispatching center and a vehicular controller is realized, so that a train safely and preferentially passes an intersection. Compared with the prior art, manual duty is omitted, manpower investment is decreased, real-time information interaction among the vehicular controller, the operation dispatching center and the traffic signal controller can be realized, so that various devices define the state of the current intersection, the operation dispatching center has a highest priority, manual priority and manual cancel requests can be realized, an annular wire and a rail circuit are omitted, and the number and the cost of the devices are reduced.

Description

technical field [0001] The invention relates to an urban rail transit signal system, in particular to a control method for a streetcar intersection signal. Background technique [0002] With the acceleration of China's urbanization process, the urban population is increasing rapidly, and the urban rail transit system with high safety is an effective way to solve the pressure of public transportation in large and medium-sized cities. As the command center of urban rail transit operation, the traffic signal control system is an important guarantee for the safe, reliable and efficient operation of urban rail transit. In the current domestic urban rail transit signal system, manual guarding is generally used to ensure the safe passage of trains at intersections. When a train passes through an intersection, the information exchange between the on-board controller, the operation dispatching center, and the intersection Need to rely on the loop and track circuit, and real-time com...
