An aircraft control system including transducers connected by interface units to an avionics network, such as an AFDX network. Each transducer is directly connected to an interface unit local to the transducer. Each interface unit is a configurable unit and has a signal processing module converting data to a format suitable for transmission over the network. Each interface unit may be configurable, via software commands, to operate in an application session mode, a data-loading mode, or a maintenance mode. Each interface unit may be directly associated with one of the software applications of the aircraft control system. The network may include a lower bandwidth part where data communication is conducted over sampling ports only. Interface units may be configured or installed using a plug and play method.

Avionics networks

A communication network on board a vehicle is a deterministic switched Ethernet network using virtual links, including a set of subscriber devices and a set of switches in which communications are performed redundantly. To manage redundancy, each data frame transmitted on a virtual link includes a frame number in a numbering field of the frame. The transmitter and/or receiver subscriber devices on the virtual link take into account a length of the numbering field equal to a first predetermined length when the BAG value associated with the virtual link is greater than or equal to a predetermined BAG value, otherwise equal to a second predetermined length greater than the first length.

A system for broadcasting an avionics temporal reference over a set of devices () of an aircraft, the system includes a master clock () configured to broadcast the avionics temporal reference via a wireless communication network () according to at least one predetermined frequency belonging to a wireless avionics intra-communication frequency band.

System for broadcasting a temporal reference in an aircraft

A subscriber of a deterministic Ethernet communication network using virtual links including a first receiver, a first transmitter, a first memory to record a configuration table relating to a set of virtual links that the subscriber can receive and/or retransmit. A processing unit is configured to implement at least one application, a reception function to receive data frames received by the first receiver, to accept the reception only of the frames corresponding to virtual links belonging to the set of virtual links and to transmit these frames to a sorting function to transmit the data frames received to the application and/or to a transmission function to dispatch the data frames received to the first transmitter while complying with Bandwidth Allocation Gap (BAG) constraints associated with the corresponding virtual links.

Onboard communication network of a vehicle and subscriber of such a communication network

The disclosure relates to a system embedded in an airplane comprising an electronic device intended to be inserted into a frame, a frame that can accommodate the electronic device, in which system the electronic device includes a radiofrequency tag reader, a radiofrequency tag, having a configuration information item, is fixed to the frame such that the radiofrequency tag reader can read the radiofrequency tag once the electronic device is inserted into the frame and the electronic device is adapted to, in a phase of configuration of the electronic device: read the configuration information item via the radiofrequency tag reader and determine a configuration of the electronic device as a function of the configuration information item read.

Configuring an embedded electronic device by reading a radiofrequency tag

The subject matter disclosed herein relates to a frame switch of an AFDX network in which the data acquisition application is decentralized. When the switch has to acquire the data transmitted on a virtual link, the switching table contains, apart from the input port and the output port (s) taken by this link, an ID representing the MAC address of the switch. The frames of this link are then not only switched but also transmitted to the network interface of the switch and processed by a dedicated application (DDA), hosted inside the switch. This application can be interrogated by a remote server and transfer the data that it has stored locally.

Distributed method of data acquisition in an AFDX network

The invention relates to a monitoring system for an aircraft platform implementing a set of avionics functions using a plurality of heterogeneous hardware and software components, including: an acquisition module for operating parameters of the components, configured to implement a plurality of communication protocols adapted to query each the component; a storage module including a database, configured to collect and store operating parameters acquired by the acquisition module in the database, and; an interface module with a plurality of clients, including a query unit configured to query the database of the storage module and supply one or several of the parameters stored in the database in response to a request made by a client; the acquisition, storage and interface modules being arranged in a three-tier architecture.

Monitoring system for an avionics platform with three-tier architecture

The disclosure relates to reconfigurable avionics equipment, subscribed to an onboard network such as an AFDX&#xae; network. The equipment has an architecture in two portions, a functional portion which makes it possible to perform the function proper to the piece of equipment and an interfacing portion, which allows the functional portion to communicate over the network. The interfacing portion includes a configuration file separate from the one used to configure the functional portion and able to be downloaded, using the network, independently of the latter.

Reconfigurable avionics equipment and method of reconfiguring such equipment

The subject matter disclosed herein relates an on-board network with nodes linked by wired links, the on-board network being partitioned into adjacent sub-networks, mutually segregated by security elements. Each sub-network can be equipped with access points allowing mobile terminals to connect to the sub-network by wireless links. The access points of adjacent sub-networks use different communication standards or distinct sets of transmission resources in such a way that the segregation between adjacent sub-networks is preserved.

Wireless partitioned on-board telecommunication network

The present invention concerns an AFDX network which is extended by a passive optical network or PON. The AFDX network comprises an AFDX switch to which are connected a plurality of equipments. The AFDX switch constitutes the optical line termination and said equipments constitute the optical network terminations of the PON. The PON broadcasts over the downlink, to all said equipments, every AFDX frame output by said AFDX switch. It also multiplexes over the uplink the AFDX frames transmitted by the same equipments. The invention also concerns an &#x3bc;AFDX network using a PON.

AFDX network with a passive optical network

A method of transmitting data over a network, from a sending application to a receiving application, including: coding the data, by the sending application, by implementing a predefined rule; detecting alteration of at least one item of data transmitted, by the receiving application, by implementing the predefined rule; and in case an alteration of a data item is detected, restoring the altered data item. In the course of the coding, in the course of the alteration detection, and in the course of the restoration, a cyclic redundancy check or an encryption can be implemented.

Method and device for protecting the integrity of data transmitted over a network

An aircraft communication system includes primary and secondary networks. The system also includes an interconnection gateway with a filtered interface connected to only one of the primary and secondary networks, and an unfiltered interface connected to the other network. The filtered interface includes first incoming and outgoing buffers, a memory, and a selector. The unfiltered interface includes second incoming and outgoing buffers. The second incoming buffer sends all frames received from the other network to the first outgoing buffer for distribution through the only one network. The selector selects common data frames corresponding to virtual link identifiers in a stored list and copies only the selected common data frames from the first incoming buffer to the second outgoing buffer of the unfiltered interface for distribution through the other one of the networks.
