Switchgear Coordinated Controller
Centralized Switchgear Coordination and Logging Controller
The Centralized Switchgear Coordination and Logging Controller is a 2 kg, 5 W unit that coordinates power distribution across 100 channels using sequence enforcement and interlocks to prevent destructive configurations. Processing authenticated commands with a 10 ms latency, it streams time-stamped event logs to L1-DVT. To survive the lunar radiation environment across a 100-year mission profile requiring durable command records, the system executes code from radiation-hardened NOR flash and dedicated FPGA logic. It achieves a 25-year service lifetime and a 300,000-hour mean time between failures, employing machine-learning anomaly detection for switch behavior to coordinate safe servicing with L1-MNT.
Centralized controller coordinating all switchgear operations with sequence enforcement, interlocks, and full event logging to L1-DVT.
Purpose
Centralized controller coordinating all switchgear operations with sequence enforcement, interlocks, and full event logging to L1-DVT.
Context
Child of L2-PDM-SWGR within the Lunar Ark system
Principles
- ▸Sequence enforcement prevents simultaneous incompatible operations
- ▸Interlocks prevent destructive configurations
- ▸Time-stamped event logging to L1-DVT
- ▸Authenticated commands per L3-COM-CRYPT-AUTH
- ▸Manual mode for maintenance with hardware override
Typical implementations
- ▸Industrial DCS switchgear control (terrestrial)
- ▸Spacecraft power-system controller heritage
- ▸NASA cFS-based control framework
Lunar considerations
- ▸100-year mission needs durable command history
- ▸Coordination with L1-MNT for safe maintenance
- ▸ML-augmented anomaly detection for switch behavior
