Problems solved by technology

[0004] With the speed increase of rail transit passenger cars and the shortening of the departure interval, the safe operation of passenger cars has a serious dependence on the dispatching command communication system. When the dispatching command center fails, it will affect the performance of the entire communication system
The current single-dispatch command center system has a serious single point of failure hidden danger

Embodiment Construction

[0045] The present invention will be further described below in conjunction with accompanying drawing:

[0046] The invention provides a method for implementing relay routing selection of dual dispatching command centers.

[0047] Set call processing module, interface management module and data management module in the dispatch command center. The call processing module is responsible for the connection and management of calls; the interface processing module is responsible for the management of terminals and trunk interfaces, and dynamically updates the interface status table (see Table 3) according to the actual interface status; the data management module is responsible for the management of call data and interface data , which includes the office routing table (see Table 1) and the relay routing table (see Table 2) data. A number table is also set in the dispatching command center switch, which contains the number of the dispatching station at this level.

Abstract

The invention discloses a implementing method of transitroute selecting for double scheduling command center. The method selects available route to establish call by setting up office direction table, transitroute table and interface state table in switch of scheduling command center, and based on route information in transitroute status and relaying call reply message. The invention implements transitroute selecting function of double scheduling command center, which can guarantee success of call scheduling to maximum limit, reduce calling process effectively, enhance reliability of the entire schedule command communication system.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a relay routing selection method for a dual dispatching command center. Background technique [0002] With the development of economy and technology, rail transit (passenger train, subway, light rail) has become an indispensable means of transportation in people's daily life, and the traffic dispatching command communication system is an effective means to ensure the safe and punctual operation of passenger cars. [0003] Figure 1 is a schematic diagram of the connection of the traditional single dispatching command center system. The dispatching command communication system has only one dispatching command center, and the dispatching communication is carried out between the center and the sub-stations under its jurisdiction through a ring relay route. When the center calls the substations, it can be made clockwise or counterclockwise, and vice versa. [0004] ...
