Level crossing system for demanding conditions
Mipro’s level crossing system is designed for the most demanding conditions and for a broad range of applications. Mipro’s LC system is ideal for primary and secondary lines, industry lines and marshalling yards. In addition to various environments, the modular level crossing system is adaptable to customer-specific requirements.
The reliability of Mipro’s LC system has been proven in approximately 100 installations in public railways since 1995.
FEATURES
Modularity for flexible system structure and functionality
Open interfaces to allow the use of existing equipment
Integrated or stand-alone solutions according to customer needs
Total solutions with flexible and cost-effective installations
Effective remote and local diagnostics to ensure high availability
Reliability and quality based on the SIL4 approved platform
PLC (programmable logic controller) based system with COTS components
MIPRO’S SOLUTIONS CAN BE INTEGRATED WITH OTHER SYSTEMS, WITHOUT ANY COMPATIBILITY PROBLEMS.
The high availability of Mipro’s LC is based on a redundant system architecture and modern COTS components.
MODULAR SYSTEM STRUCTURE
Mipro’s LC system provides a modular and highly scalable system structure for both hardware and software. It can therefore be flexibly adapted to various requirements and applications. Software configuration is based on the track geometry and can be easily modified in the event of alterations and extensions. Hardware configuration is fully modular which allows easy extensions to be made when needed.
Mipro’s LC controls and monitors train signals and road signals, barriers and lights, and warning bells for road traffic. It provides level crossing control for one track or several tracks and for a varying number of signals, barriers and lights according to needs.
OPEN INTERFACES
Mipro’s LC system is provided with open interfaces. It is capable of utilising existing level crossing equipment and thus allows effective level crossing modernisations in any environment. The system is connectable to various types of equipment whether they are determined by national requirements or by the application.
Open interfaces also enable the use of various techniques for line vacancy detection. Mipro’s LC system starts and stops warnings on the basis of alarms that can be initiated by track circuits, audio frequency track circuits, axle counting, local control or via remote control from the train. Moreover, any other technique in use, such as ultra sound or inductive detection, can initiate the alarm.
TOTAL SOLUTION
Mipro provides total solutions for the control of level crossings. Mipro’s LC solution covers – besides technology and equipment – design, commissioning and subsequent maintenance. When designing and implementing Mipro LC system solutions, we always take international and national standards fully into account.
Mipro’s LC system technology is based on a SIL4 certified (TÜV Süd) system platform, reliable electronics and field-proven connection principles.
Diagnostics
EFFECTIVE REMOTE AND LOCAL DIAGNOSTICS TO ENSURE HIGH AVAILABILITY
Mipro LC provides versatile remote diagnostics to facilitate system maintenance and thus ensure high availability. It is capable of utilising several wireless data transmission protocols, such as 3G, @450 and GSM-R, to transmit critical information and diagnostic data.
The system transmits failure data, including failure type and urgency level, directly to maintenance personnel: to their phones or user interfaces. Failure alarms are also transmitted to traffic controllers’ user interfaces and indicated on-site. On-site alarms are visible on the failure display located in the field cabinet or any
location where the equipment is installed.
Implementation
INTEGRATED OR A STAND-ALONE SOLUTIONS AS PER CUSTOMER NEEDS
Mipro LC can be implemented as a stand-alone system or it can be integrated into the Mipro interlocking system. When integrated into our interlocking system, all fault indications and level crossing status data are transmitted through the interlocking system.
For the stand-alone solution, Mipro LC provides a communication interface to transfer safety critical information on train routes and barrier positions from and to the interlocking system. If necessary, fault indications can be directed to other destinations – to maintenance laptops and emergency centres, for example.
SIL4 system platform
RELIABILITY AND QUALITY BASED ON A SIL4 APPROVED PLATFORM
Mipro LC is designed for demanding conditions. Hardware has a robust, solid construction and components have been tested in extreme conditions.
The LC system is approved by the Finnish Transport Infrastructure Agency. It conforms to CENELEC standards EN 50126, EN 50128 and EN 50129 on Safety Integrity Level SIL4. It also meets the requirements of the Safety Management System which means that general and branch-specific safety automation standards are fulfilled in system development work and project implementation.
ILMALA MARSHALLING YARD MODERNISATION PROJECT, 2007-2012
Mipro delivered nine level crossing systems to the Ilmala marshalling yard in its modernisation project. The level crossing systems are integrated into the interlocking system.
