SnS Wire Fault Detection
Sital’s SnS Wire Fault Detection IP technology acts as a versatile wire fault detector applicable to all data bus interfaces. This technology provides continuous real-time detection and location of intermittent or continuous open or short circuit faults in data bus cables, bus couplers, connectors, stubs, LRUs, and bus terminators.
These include both single-wire and two-wire faults, along with short circuit faults between two data bus wires or between one data bus wire and ground.
The capability to detect and locate intermittent faults enables preventive maintenance prior to faults becoming continuous when they can render a data bus inoperative. Metrics and advanced diagnostics can be viewed on a computer screen to see how the system is running.
With Sital’s SnS Wire Fault Detection technology, a disconnected or shorted wire is registered immediately as is its location and effect on a system. Sital’s wire fault detection sensors provide the fastest fault detection and are the most accurate in registering intermittent faults during flight.
In addition to resolving many no-fault-found issues, it can distinguish between module and wire faults. The result is more accurate network prognostics and the ability to implement an effective repair strategy that resolves potentially mission-threatening failures.
Frequently Asked Questions (FAQ)
What is the SnS Wire Fault Detection System?
The SnS Wire Fault Detection system is a real-time technology designed to detect and pinpoint wiring faults (intermittent or continuous) in data bus systems, including MIL-STD-1553, CAN bus, ARINC-825-4, and ARINC-429.
What types of faults can the SnS system detect?
It detects open or short circuits in data bus cables, connectors, stubs, and terminators. It also differentiates between module and wire faults, ensuring accurate diagnostics.
How does the system support preventive maintenance?
The system detects intermittent faults early, before they become continuous, enabling preventive maintenance and reducing the risk of mission-critical failures.
Can the system handle multiple buses?
Yes, the system is scalable across multiple platforms and can be configured to monitor and protect all data buses from a single gateway or avionic unit.
Does SnS interfere with normal bus operations?
No, it operates passively, monitoring the system without transmitting on the data buses, ensuring no interference.
What protocols does the system support?
It supports MIL-STD-1553, CAN bus, CAN bus FD, ARINC-825-4, and ARINC-429 protocols.
Can SnS detect cybersecurity threats?
Yes, SnS detects cybersecurity threats like spoofing attacks through continuous real-time authentication, enhancing system security.
How does the SnS system help with “no-fault-found” issues?
By accurately identifying intermittent faults and distinguishing between wire and module issues, the system reduces unresolved diagnostic problems, improving repair accuracy.
Is SnS compatible with existing systems?
Yes, it can be easily integrated into existing systems or embedded in standalone units, providing flexibility in implementation.
What industries benefit from the SnS system?
It is designed for aerospace, automotive, and defense applications, ensuring safe and secure communication across various high-demand environments.
