safety reliability issues
Safety & Reliability Issues
  • Safety –
    • Don’t want to electrocute users
    • Don’t want to harm connected appliances
  • Reliability –
    • RF Reliability Issues (interference, etc)
    • Sensor failures
components
Components
  • Linx Transceiver (TRM-315-LT)
  • Freescale Micro-Controller (MC9S12A512)
  • Fairchild Semi-ConductorVoltage Regulator (7805)
criticality levels
Criticality Levels
  • Low: The management system no longer works. The data may not be collected/displayed correctly or valid and the user may not be able to send commands.
  • Medium: The devices plugged into our adapter may not be provided correct voltage/current and they may not function.
  • High: Devices or Users may be harmed.

risk mitigation
Risk Mitigation
  • Fuses at source and at solid state relays
  • Ground body of adapters
  • SSRs offer improved system reliability because they have no moving parts or contacts to degrade
  • Checks for validity of communication
