Abstract

A control system for a machine comprising a plurality of independently replaceable machine modules comprises a controller operable to control operation of the machine. Memory stores machine data for use by the controller. Communication means are operable to provide communication for data transfer between the controller and the memory. The memory includes a plurality of memory modules associated with respective machine modules. Each of the memory modules is replaceable with the respective associated machine module and independently of other memory modules. The communication means is operable to provide communication for data transfer between the controller and a replacement memory module associated with a replacement machine module.

Claims

1. A control system for use with a machine, the system comprising:

a plurality of independently replaceable machine modules;

a controller configured to control an operation of the machine;

a non-transitory computer readable memory configured to store machine data for use by the controller, the memory including a plurality of memory modules associated with respective machine modules, each of the memory modules being configured to be replaced such that a replaced memory module of the plurality of memory modules is removed prior to a replacing memory module being installed, each of the memory modules being replaced with the respective associated machine module and independently of other memory modules; and

a communication means for communicating a data transfer between the controller and the memory, the communication means communicating a data transfer between the controller and a replacement memory module associated with a replacement machine module, wherein

data stored in the memory is updated by the controller to reflect an operational history of the machine.

2. The system according to claim 1, wherein at least one of the memory modules is mounted with the respective associated machine module such that the memory module is removable, and is replaced when the respective associated machine module is removed and replaced.

3. The system according to claim 2, wherein the memory module is carried by the respective associated machine module.

4. The system according to claim 2, wherein at least one of the memory modules is mounted independently of the respective associated machine module.

5. The system according to claim 1, wherein the controller is replaceable independently of the memory modules or machine modules, and the communication means is configured to communicate a data transfer between the memory modules and a replacement controller.

6. The system according to claim 1, wherein the controller is configured to store in the memory modules data specific to the respective associated machine module.

7. The system according to claim 6, wherein the specific data relates to the identity, type, version, history, calibration, trim or deterioration through use of the associated machine module.

8. The system according to claim 1, wherein the machine is a gas turbine engine.

9. The system according to claim 1, wherein the control of the machine by the controller is dependent, at least in part, on data retrieved by the controller from one or more memory modules.

10. The system according to claim 1, wherein the controller is configured to maintain and update the data in each memory module so that the data continues to reflect the operational history of the associated machine module.

11. A machine comprising:

a plurality of independently replaceable machine modules;

a controller configured to control an operation of the machine modules;

a plurality of memory modules associated with respective machine modules, each of the memory modules being configured to be replaced such that a replaced memory module of the plurality of memory modules is removed prior to a replacing memory module being installed, each of the memory modules being replaced with the respective associated machine module and independently of other memory modules; and

a communication means for communicating a data transfer between the controller and the memory modules of the machine modules currently forming the machine, wherein

data stored in the memory is updated by the controller to reflect an operational history of the machine.

12. The machine according to claim 11, wherein the controller is configured to maintain and update the data in each memory module so that the data continues to reflect the operational history of the associated machine module.

13. A control system for a machine comprising:

a plurality of independently replaceable machine modules;

a controller configured to control an operation of the machine;

a non-transitory computer readable memory configured to store machine data for use by the controller, the memory including a plurality of memory modules associated with respective machine modules, each of the memory modules being configured to be replaced such that a replaced memory module of the plurality of memory modules is removed prior to a replacing memory module being installed, each of the memory modules being replaced with the respective associated machine module and independently of other memory modules; and

a wired or wireless communication device configured to communicate a data transfer between the controller and the memory, the wired or wireless communication device being configured to communicate a data transfer between the controller and a replacement memory module associated with a replacement machine module, wherein

data stored in the memory is updated by the controller to reflect an operational history of the machine.

14. The system according to claim 13, wherein the controller is configured to maintain and update the data in each memory module so that the data continues to reflect the operational history of the associated machine module.
