Abstract: A process for transmitting asynchronous data packets includes a step of starting a packeting operation. After receiving a message from a message composition module, the process interrupts the packeting operation based on the message. A packet formed during the packeting operation prior to the interrupting step is transmitted. The steps are repeated so as to transmit a plurality of packets.

Abstract: A system for processing asynchronous data includes a plurality of packeting modules configured to packet asynchronous data; and a message composition module connected to the plurality of packeting modules. The message composition module is configured to send a request for a packet to a packeting module of the plurality of packeting modules. The packeting module is configured to stop packeting asynchronous data in response to the request and to send to the message composition module a packet of asynchronous data formed prior to receiving the request.

Abstract: A deterministic transmission process for asynchronous data in packets stores data arriving in an asynchronous manner in registers as and when it arrives. The data is sent to one of several packeting modules, which conduct start of packeting, packeting with sorting and enhancement of data, end of the packeting, and sending of the made-up or assembled packets to a message composition module at the request of the message composition module during the realization cycle of the packet, so that a new realization cycle is commenced. The packets are recovered one after another, in a predefined order, in the message composition module. The message thus composed is set in the electrical format in the protocol used for transmission.

Abstract: A flight test installation system for collecting aircraft data includes a sensor level configured to convert aircraft physical inputs into plural measurable electrical parameters, an acquisition level configured to perform at least one of an analogue, discrete or digital bus data acquisition to acquire each of the plural measurable electrical parameters, and a concentration level configured to receive data streams from each of the analogue, discrete and digital data buses, and to switch and duplicate frames in the received data streams without modifying a content of the data streams. The flight test installation system also includes a recording and analysis level configured to record and analyze the content of each of the data streams.

Abstract: The invention relates to a switched flight test installation with an architecture based on four data levels and for which all dated parameters are transported in a single <<packet>> type format: a first level (L1), or sensor level, in which the data are converted from a physical magnitude (pressure, temperature, force . . . ) into an electrical magnitude, a second level (L2), or acquisition level, in which the analogue, discrete or digital bus acquisition is made, a third level (L3), or concentration level, carrying data streams from all second level (L2) systems to fourth level (L4) systems, a fourth level (L4), or recording and analysis level.

Abstract: A process for transmitting asynchronous data packets includes a step of starting a packeting operation. After receiving a message from a message composition module, the process interrupts the packeting operation based on the message. A packet formed during the packeting operation prior to the interrupting step is transmitted. The steps are repeated so as to transmit a plurality of packets.

Abstract: The present invention concerns a deterministic transmission process for asynchronous data in packets, in which the data arriving in asynchronous manner is stored in batteries (11) as and when it arrives, the said process comprising the following stages:
