1. Scope
The Electronic Interlocking Equipment incorporates microcomputers to realize interlocking
functions using the hardware and software developed originally.
One of the features of this Electronic Interlocking Equipment is that it consists of Interlocking
Logic Module, Electronic Terminal Modules and Journal Module. Processing cards realize
high-speed processing and transmission using fail-safe microcomputers. The Electronic
Interlocking Equipment is highly immune to various emissions (certified for EMC by the
international standards) and other climatic conditions, provides high-quality interlocking
operation, and is highly expansible. Interlocking data of each station are created using offline
equipment. Therefore, the data can be validated off line, and collected into the Interlocking
Logic Module and Electronic Terminal Modules.
This manual describes for the maintenance personnel, basic handling methods, operation
procedures, precautions, etc. Maintenance personnel are requested to read through the manual
to ensure safety of people and equipment.
In the K5BMC system manufactured by Kyosan, external units of the points, the signals, the
level crossings, blocking work and the crank handles etc. are controlled through the relay
interfaces. The EI system, the ATP and the CTC system can be interfaced by adding more
hardware.
In case of end cabin and multi cabin operations, 2 or more CCIPs or VDU control consoles, or
both of them can be interfaced to the EI system.
The K5BMC system has been isolated from external devices electrically by the relays and it is
corresponding to in the AC electrified sections.
The K5BMC system is capable of interfacing with block instrument. Also, it is capable of
interfacing with the intermediate block signals and the automatic block signals including the
outlaying yards. This can be achieved by the relays and the logic circuits.
For large stations which cannot be processed by one EI, 2 or more EI logic modules can be
connected via signal LAN.
The signal LAN has a fail-safe feature.
For all the vital connections, the OFCs or the twisted pair cables have been applied.
