Abstract
Systems and methods involving multiplexed engine control signals are provided. In this regard, a representative engine control system for a gas turbine engine includes: a signal relay device operative to receive multiplexed signals from an engine electronic control (EEC), demultiplex the signals, and provide demultiplexed signals to corresponding ones of multiple control devices of the engine.
Claims20
A gas turbine engine system comprising:
- an engine electronic control (EEC) operative to receive and provide information corresponding to engine operating parameters such that a gas turbine engine operates in accordance with the information provided from the EEC;
- multiple control devices, each of the control devices being operative to perform at least one of:
- monitoring at least one engine operating parameter, providing information corresponding to the at least one engine operating parameter for use by the EEC, and affecting at least one engine operating parameter;
- and
- a signal relay device operative to receive multiplexed signals from the EEC, demultiplex the signals, and provide demultiplexed signals to corresponding ones of the multiple control devices.
An engine control system for a gas turbine engine having multiple control devices, said engine control system comprising:
- a signal relay device operative to receive multiplexed signals from an engine electronic control (EEC), demultiplex the signals, and provide demultiplexed signals to corresponding ones of the multiple control devices.
A method for controlling a gas turbine engine having multiple control devices, said method comprising:
- multiplexing, at a first location, engine control signals corresponding to the multiple engine control devices;
- demultiplexing the multiplexed engine control signals at second location;
- and
- providing each of the demultiplexed engine control signals to a corresponding one of the multiple control devices.
