Problems solved by technology

[0003] ① To adopt the centralized interlocking mode, it is necessary to establish a data table that centrally describes the equipment of the whole station and their mutual relations, and contains a large number of complex and tightly coupled data tables with different attributes; the logical relationship between the software modules that realize the centralized interlocking function is complex and close Coupling increases the difficulty of software testing and security assessment certification, which may lead to serious errors and defects in the software, and the system has serious risks in terms of reliability and security.
[0004] ③The construction of the system also contains a strong research and development component. The installation and debugging of the system are highly dependent on the manufacturers of computer interlocking equipment, which seriously affects the speed of emergency system construction.
[0005] ④Centralized power supply mode, the power supply network of the system is very complicated and a large number of power supply cables need to be borrowed from the past or re-laid, which brings difficulties to the construction and rush construction
[0006] ⑤ The optional power supply types are single. If the system is severely damaged and there is no AC380V power supply or even no power supply in the station, the emergency signal system will not work

Embodiment 1

[0028] Example 1 is as figure 1 As shown in the figure, the station signal emergency computer interlocking control system consists of three layers: the human-computer interaction layer, which realizes the function of operation display; Measurement and control drive function, the unit is installed next to the outdoor trackside equipment (such as signals, turnouts and track circuits, etc.); the outdoor equipment layer, this layer is for signals, turnouts and track circuits and other equipment.

[0029] Among them, the human-computer interaction layer and the interlocking layer are connected through a redundant wired or wireless communication network; the interior of the interlocking layer is connected through a redundant wired communication network; the connection between the basic interlocking unit and the outdoor equipment is the same as the existing interlocking system . In addition, the power supply of the system adopts AC380V centralized power supply mode.

Embodiment 2

[0030] Example 2 is as figure 2 As shown, the difference from Embodiment 1 is that the power supply of this embodiment adopts the distributed battery power supply mode. In this embodiment, different types of batteries are separately powered according to the power consumption of each functional layer. Each functional layer, including the communication network part, is equipped with its own battery power supply, which is supplied to the switch, the channel and the track. The built basic interlock control and its fully electronic interface unit are each equipped with an independent battery power supply.

Abstract

The invention provides a station signal emergency interlocking control system. The system distributes the interlocking logical operation function into a basic interlocking control unit using outdoor equipments such as a signaler, a switch and a track circuit as basic observing and controlling objects by adopting a distributed interlocking mode, so that each basic interlocking control unit processes the interlocking logical operation function related with the corresponding observing and controlling object equipment independently and respectively, and the interlocking function is fixed and single. In addition, the system adopts selectable centralized or distributed power supply mode, the power supply mode is flexible and practical for emergency.

Description

technical field [0001] The invention relates to a rail transit operation control system, in particular to a rail transit station signal interlocking system. Background technique [0002] The station signal interlocking control system is a command, control and safety protection system that directs the trains to complete the technical operations in the station and ensures their safe operation. Once the system is damaged by fire, flood, war or terrorist attack, it will seriously affect the efficiency and safety of railway transportation. At present, there are two types of systems for realizing station signal interlocking at home and abroad, one is the station signal electrical centralized interlocking system; the other is the computer interlocking control system. Regardless of the type of system, once a major accident or disaster occurs, the signal interlocking system of the station will be seriously damaged, and it will take several days or even longer to complete the emergen...
