Computer-based Interlocking System(iLOCK)

iLOCK computer-based interlocking system is a “2oo2×2” system developed solely by CASCO with full intellectual property rights. The system passed the safety authentication of SIL4 conducted by TÜV of Germany, an international safety certification third party on October 28th 2009, which demonstrated that the safety level of iLOCK has reached the highest level, i.e. SIL4 of CENELEC. On December 20th 2013, the generic application of iLOCK system also passed the third-party safety authentication of SIL4, proving that iLOCK has reached SIL4 of CENELEC from the product to the application.

System Advantages

Safety
  • The product as well as the application of iLOCK system has passed the SIL4 independent safety authentication by an international third party.
  • iLOCK system integrates “2oo2” and double-break stable output technology, and independent safety validation subsystem VPS is added on the basis of numerically integrated safety-assurance logic technology to ensure the safety of the system.
 
Reliability
  • iLOCK system is designed with multi-redundant structure and additional technologies like collection sharing and paralleled output control by dual systems, thus ensuring high reliability.
  • iLOCK uses multi-processors, independent computer power supply protection and partitioned filtering, so that the system has great lightening protection and anti-interference capabilities.
 
Maintainability
  • With open designing language, iLOCK system has good readability.
  • With electronic-guided diagnostic function, iLOCK can track the output or input failure to code level.
  • iLOCK boasts the function of online version validation so as to achieve process tracking and version management of system design.
  • iLOCK is designed with embedded on-site simulation test interface and vital check-out or check-in design of simulation test data is involved in application software. When the system is upgraded or under daily check, one set of equipment can be upgraded and tested while the other maintains uninterrupted running so that the upgrade of the whole station and the test of interlocking function can be completed without affecting the normal operation.
