Problems solved by technology

In this implementation, the relay part and the trackside part adopt the simulation mode. Due to the simulation mode, the interface mode is different from the engineering application site, and there is a big difference from the actual connection on site.

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the drawings and specific embodiments are only exemplary, and should not be construed as limiting the protection scope of the present invention.

[0019] figure 1 The principle of the embodiment of the simulation test system for interlocking signal equipment based on field relay deployment of the present invention is shown. See figure 1 , The system of the present embodiment is formed by connecting the interlocking system, the driving and mining controller, and the relay combination rack in pairs.

[0020] The interlock system is the core control equipment responsible for railway traffic. The (computer) interlock system realizes the interlock control among the turnouts, signal machines and track circuits in the station under the operation of signal personnel. It is an indispensable gua...

Abstract

The invention discloses an interlocking signal equipment simulation test system based on-site relay deployment. Test verification equipment which replaces a trackside equipment state with a relay state is adopted; an engineering field state is restored to the maximum extent; interlocking software logic and driving and collecting hardware can be verified at the same time; and the problem that a laboratory test is incomplete is solved. According to the technical scheme, the system comprises an interlocking system, a driving and collecting controller and a relay combination frame; the interlocking system, the driving and collecting controller and the relay combination frame are electrically connected in pairs; the driving and collecting controller is used for driving and collecting a relay inthe relay combination frame; and the driving and collecting controller carries out trackside equipment fault injection by changing the state of the relay and feeds back the collected state of the relay to the interlocking system.

Description

technical field [0001] The invention relates to test verification technology, in particular to the test verification of computer interlocking systems, which can be applied to the interlocking system test verification work of urban rail transit signal systems, national railway signal systems, local railway signal systems, and enterprise railway signal systems. Background technique [0002] The computer interlocking system can be applied in the fields of railway trunk lines, urban rail transit, etc. Before the computer interlocking system is put into operation, laboratory tests and on-site tests are required. In laboratory testing, computer simulation technology is often used to test it. This method is mainly for functional testing of interlocking software, but lacks testing of driving and mining hardware, and cannot comprehensively test and verify the engineering application of interlocking systems. . [0003] The existing signal equipment simulation test system is connected...
