Problems solved by technology

[0003] At present, the computerized interlocking system used in urban rail transit in China is basically the system previously used in national railways. Although it can realize interlocking control under fixed blockage, it has limited support for interlocking control under moving blockage. To meet the operational needs of urban rail transit, seriously affecting operational efficiency
However, the computer interlocking system used abroad is difficult to quickly respond to the actual situation in the application

Embodiment 1

[0038] This embodiment introduces a computer interlocking system applicable to train control systems, such as figure 1 As shown, it is at least composed of an interlock control unit and an input and output unit, and HVB high-speed bus communication can be used between each unit. The functions of each part are described below.

[0039] The interlock control unit mainly receives the interlock operation command, and according to the current status information of each signal device, performs the interlock logic operation of two times two to take two for the received interlock operation command, and determines the result according to the result of the interlock logic operation Status information of the signal equipment to be controlled by the interlock operation command;

[0040] from figure 1 It can be seen that the interlocking control unit is the computing core of the system, and the interlocking control unit is connected with ATS and ZC through Ethernet for two-way, reliable ...

Embodiment 2

[0064] This embodiment introduces a method for controlling urban rail transit signals by a computer interlocking system, which can be realized by the computer interlocking system provided in Embodiment 1 above, and the method includes:

[0065] When the computer interlocking system receives the interlocking operation command, according to the current state information of each signal device, it performs an interlocking logic operation of two times two to get two for the interlocking operation command, and determines the State information of the signaling device to be controlled by the interlocking operation command, outputting driving information to the signaling device to be controlled by the interlocking operation command to control the signaling device to reach a determined state.

[0066] When the computer interlocking system receives the interlocking operation command, according to the current status information of each signal device, the interlocking logic operation of two...

Abstract

The invention claims a computer interlock system and method for controlling urban rail transit signals thereof, which relate to urban rail transit signal control field. The computer interlock system disclosed in the invention at least comprises an interlock control unit and an input and output unit, wherein the interlock control unit carries out a double two out of two interlock logical operation of according to state information of each signal device when receives an interlock operating command, and determines the state information of the signal device to be controlled by the interlock operating command according to the result of the interlock logical operation and outputs to the input and output unit; the input and output unit outputs driving information for controlling the signal device to reach the determined state to the signal device to be controlled by the interlock operating command. The example in the application can guarantee a subway system to operate safely and reliably; and the embodiment in the application is not only suitable for moving block, but also suitable for quasi moving block and fixed block, and is high in flexibility.

Description

technical field [0001] The invention relates to the field of urban rail traffic signal control, in particular to a computer interlocking system and a method for controlling urban rail traffic signals. Background technique [0002] Urban rail transit has now entered a stage of rapid development. As the basic equipment of urban rail transit signal system, computer interlocking system has become a top priority for its localization and technical problems to ensure safe, punctual, high-density and high-efficiency transportation of passengers. [0003] At present, the computerized interlocking system used in urban rail transit in China is basically the system previously used in national railways. Although it can realize interlocking control under fixed blockage, it has limited support for interlocking control under moving blockage. Satisfying the operational needs of urban rail transit seriously affects operational efficiency. However, the computer interlocking system used abroad...
