RTS Instrumentation Architecture

The architecture for the instrumentation (sensors and actuators) subsystem of the RTS demonstrator.

RTS Instrumentation Systems Architecture

The systems architecture for the instrumentation subsystem of the RTS demonstrator. Some of the architecture is implemented in hardware, and some is implementated in software.

Instrumentation Implementation (InstImpl)

A software or hardware driver that interfaces with a sensor. In the RTS demonstrator there are two kinds of sensors: pressure and temperature.

• inherits Driver

Actuator Implementation (ActImpl)

inherit Driver A software or hardware driver that interfaces with an actuator. In the RTS demonstrator there is one kind of actuator: a solenoid.

Voting Implementation (VoteImpl)

inherit Voting A software or hardware implemenation of our voting algorithm that provides fault tolerance for decision-making based upon the attached components' inputs.

Instrumentation Software Stack (SWStack)

inherit Software The software stack associated with the instrumentation subsystem.

Instrumentation Implementation 1 (InstImpl1)

The first of four sensor drivers for the instrumentation subsystem.

Instrumentation Implementation 2 (InstImpl2)

inherit InstImpl The second of four sensor drivers for the instrumentation subsystem. There are multiple sensors in the architecture to provide fault tolerance.

Actuator Implementation 1 (ActImpl1)

inherit ActImpl The first of two actuator drivers for the instrumentation subsystem. There are multiple actuators in the architecture to provide fault tolerance.

Voting Implementation 1 (VoteImpl1)

inherit VoteImpl The first of two implementations of the voting component. Voting is used to implement redundancy of instrumentation and control in the RTS demonstrator.

Instrumentation Actuation and Voting Hardware Stack (HWStack)

The hardware implementations driving a redundant subset of sensors, actuators, and voting components.

Instrumentation Implementation 3 (InstImpl3)

inherit InstImpl The third of four sensor drivers for the instrumentation subsystem. There are multiple sensors in the architecture to provide fault tolerance.

Instrumentation Implementation 4 (InstImpl4)

inherit InstImpl The fourth of four sensor drivers for the instrumentation subsystem. There are multiple sensors in the architecture to provide fault tolerance.

Actuator Implementation 2 (ActImpl2)

inherit ActImpl The second of two actuator drivers for the instrumentation subsystem. There are multiple actuators in the architecture to provide fault tolerance.

Voting Implementation 2 (VoteImpl2)

inherit VoteImpl The second of two implementations of the voting component. Voting is used to implement redundancy of instrumentation and control in the RTS demonstrator.
