Problems solved by technology

The downside is that RCEs - even if they have to meet certain quality regulations - all have different functional processes
This makes it difficult to find errors

Embodiment Construction

[0024] figure 1 A multi-channel control control module with two channels "channel A" and "channel B" is schematically shown. Each of "channel A" and "channel B" has a first interface with input / output functions or I / O functions, a processor "CPU" and a second interface "TC". In the first operating mode "duplex processing", the two channels "channel A" and "channel B" are connected to each other for interactive data exchange. The two channels "Channel A" and "Channel B" monitor the consistency of the data processed by each. in figure 1 The two channels "channel A" and "channel B" are separated from each other in the second operating mode "duplex simplex processing" additionally shown in. There is no data exchange between the two channels "Channel A" and "Channel B" to identify errors.

[0025] figure 2 The hardware architecture "RCE" of the multi-channel control module is schematically shown. The hardware architecture is divided into a "processing board" on which a microproces...

Abstract

The invention relates to a multichannel controller module for integrated modular avionics, having at least two channels, wherein for each of the channels at least one first interface for communicating with a control computer, a processor, at least one second interface for communicating with a peripheral device, and a first memory having an operating system are all connected to each other for data exchange, wherein a second memory is provided for selectively storing at least one application program for communicating with the peripheral device, wherein a selecting means is provided by means of which the application program can selectively be associated with a first or a second operating mode, wherein the first operating mode is a redundant duplex operating mode, wherein both channels are used for executing the application program and the two channels, in this case, are connected to each other by means of data exchange and error monitoring means, and wherein the second operating mode is a non-redundant simplex operating mode, wherein only one of the two channels is used for executing the application program and, in this case, the data exchange and error monitoring means is deactivated.

Description

Technical field [0001] The invention relates to a multi-channel control module for integrated modular avionics (IMA). Background technique [0002] According to the prior art, a multi-channel control module with two channels is known from US 5,406,702, where the interface, the processor and the first memory at each channel are connected to each other for data exchange. The two channels operate in a redundant duplex operating mode, in which both channels are used in order to run a fixed program and are connected to each other through data exchange and error monitoring devices. If it is confirmed that there is an error through this data exchange and error monitoring device, the incorrectly working channel will be closed. [0003] EP0435613A2 announced another multi-channel control module. Here, each channel has at least one interface for communicating with the control computer, a processor, at least one second interface for communicating with peripheral devices, and a memory for da...
