Compute Interlocking System (VPI)
VPI is the compute interlocking system with independent fail-safe check module and NISAL technology based on the common dual system hot-standby structure, and realizes dual system parallel control.
VPI is equipped with interfaces of on-site simulation test and factory test. Its interlocking function, system reliability, maintainability, loading capacity and anti-interference capability all conform to relevant industry standards as well as actual requirements of the site. Also the lightening protection capability and EMC of both software and hardware of the system have passed the test of National Railway Administration.
In 2015, the product and application of VPI have passed international third-party SIL4 certification and got CRCC certificate in December of the same year.
The product and application of VPI system have passed independent third-party SIL4 safety certification.
VPI is the hot redundant computer interlocking system with the check CPU, and it adopts programmable safety system design technologies such as “NISAL technology”, “I/O port independent different check-word dynamic test in 50ms cycle”, “independent timer”, “double channels different software”, “inherent fail-safe”, “composite fail-safe” and “reactive fail-safe” to guarantee the system safety.
VPI applies redundant technologies such as “collection sharing” and “paralleled output” to improve system reliability.
With open design language in application software , VPI system has good readability.
With electronic-guided diagnostic functions, the output or input failure of VPI system can be tracked back to code level.
VPI is provided with the function of online version validation so as to achieve process tracking and real-time version management.
VPI is equipped with on-site simulation test interface. When the system is upgraded or under daily check, one set of equipment can be upgraded and tested while the other set maintains uninterrupted working.
