Definitions
- the invention relates to an electromagnetic compatibility test module of a high-speed Ethernet interface embedded on an aircraft.
- the certification of an Ethernet network on aircraft involves the demonstration of the electromagnetic behavior of the equipment involved.
- a test method known in the art entitled “BuIk Current Injection” or BCI, is described in the document referenced [1] at the end of the description.
- BCI BusIk Current Injection
- a current injection simulating electromagnetic aggression, is performed using a magnetic core associated with a cable.
- the cable resonates in the useful band of the signal (below 65 MHz), resulting in "on test” zones (very large voltages peaks: greater than about 100 volts) and zones of " under test "(very low voltage dips: about 60 millivolts).
- test cable also poses a problem of sensitivity to the test installation used: the results obtained are, in fact, very sensitive in particular to the length of cable used and the manner of install this one, which prevents a reliable and reproducible implementation.
- the subject of the invention is an electromagnetic compatibility test module of a high-speed Ethernet interface embedded on an airplane which enables:
- the invention relates to an electromagnetic compatibility test module of at least one high speed Ethernet interface embedded on an aircraft, characterized in that it comprises:
- the ends of the cable are equipped with two female "quadrax" type contacts. Both connectors are RJ45 type connectors.
- the module of the invention is made in a flattened case directly on a ground plane with an adhesive copper, with a braided connection screwed onto this ground plane.
- the attenuation simulation means comprise at least one isolator connected to a filtering module.
- the module of the invention comprises an aircraft cable capable of being connected to a device under test, which comprises a pair of wires for transmitting, and a pair of wires to receive and, on the transmission path, a first isolator connected to a first filter module and, on the reception channel, a second isolator connected to a second filter module.
- test module of the invention is easy to install, easy to use, and allows reproducible results despite the high frequencies involved.
- FIG. 1 is a logarithmic curve representing a transmitted signal (in volts) as a function of frequency (in MHz), illustrating the operation of a test method of the known art.
- FIG. 2 illustrates the electromagnetic compatibility test module of the invention, in a first test configuration.
- FIG. 3 illustrates an exemplary embodiment of the test module of the invention.
- FIG. 4 is a curve in logarithmic coordinates representing a signal (in volts) as functions of the frequency (in MHz) illustrating the operation of the module of the invention.
- FIGS 5 and 6 illustrate two test configurations using the module of the invention.
- the electromagnetic compatibility test module of a embedded high speed Ethernet interface on aircraft of the invention comprises:
- This module creates an interface between the "plane world” (on the left in the figure) and the "test world” (on the right in the figure). It allows isolation between these two worlds.
- This module 10 is thus connected on the one hand to a test equipment 11 which is an airplane computer that one seeks to test, for example the flight control computer, and on the other hand to the test equipment 12 , which may be, for example, that described in the document referenced [2] (Ethernet test equipment) and [3] (service for performing a test called "Bit error rate").
- a test equipment 11 which is an airplane computer that one seeks to test, for example the flight control computer
- test equipment 12 which may be, for example, that described in the document referenced [2] (Ethernet test equipment) and [3] (service for performing a test called "Bit error rate").
- this module includes:
- a cable 13 for example of a length of about 50 cm, whose ends are equipped with two contacts of the "quadrax" type 14 (aircraft contacts) females, the equipment (or “End System ”) AFDX to be tested 11 being equipped with male contacts, on the other side of two connectors of the RJ45 type (PC type interface or "Personal Computer”) connected to the transceivers 16 of the test equipment 12, in order to be compatible with a test equipment of the trade, and
- a current injection 17 is performed on the two paths of the cable 13.
- the test equipment 12 can thus send messages (frames) numbered 1, 2 n to the equipment under test 11. The equipment under test 11 can then send back these messages. The test equipment 12 can then verify the identity between the sent messages and the received messages. If there is no identity and a message is corrupted, there is a problem on the line, and the test is not acceptable.
- the equipment under test 11 may be provided with a high speed Ethernet interface. But the test module of the invention also makes it possible to simultaneously test two high-speed Ethernet interfaces thanks to its two channels.
- FIG. 3 illustrates an exemplary embodiment of the test module of the invention 10 thus making it possible to perform signal attenuation and electromagnetic protection of the interfaces of the test equipment 12.
- This figure illustrates a single test channel, with an aircraft cable 20 capable of being connected to the equipment under test 11, which comprises a pair of son 21 for transmitting (Tx), and a pair of wires 22 for receiving (Rx), connected to two housings 23 and 24.
- an aircraft cable 20 capable of being connected to the equipment under test 11, which comprises a pair of son 21 for transmitting (Tx), and a pair of wires 22 for receiving (Rx), connected to two housings 23 and 24.
- a first isolator 25 associated with an assembly 26 of two resistors R (in parallel to be able to withstand a large current) and a capacitor C, is connected to a first filtering module 27 composed of two resistors.
- RF filtering and CF filtering capability itself connected to a housing 28.
- a second isolator 30, associated with a set 31 of two resistors R in parallel and with a capacitance C, is connected to a second filtering module 32 connected to a housing 33.
- the test equipment 12 is connected to the housings 28 and 33 by a standard Ethernet cable 35 as short as possible.
- Adjusting the RF and CF components allows you to adjust the value of the desired attenuation, depending on the length of the aircraft.
- Such a module makes it possible to obtain the signal illustrated in FIG. 4, in which the first resonances (zones on test and zones under test) are pushed back beyond 80 MHz.
- test module of the invention can be used in three different test configurations.
- the current injection is carried out on the cable 13.
- test module 10 of the invention is looped back on the equipment under test 11 by means of a cable 37, which connects an output of this module to an input of the equipment 11.
- the current injection 17 takes place on the cable 36.
- test module of the invention has its two outputs connected to each other with a connecting cable 38 as short as possible connecting the two contacts 15.
- test module of the invention has the following characteristics:
- the cable 13 used on the equipment under test side is a cable approximately 50 cm long, the ends of which are adapted with female quadrax contacts 14.
- test equipment side The connection of the test equipment side is made through connectors 15 RJ45 type.
- a robust and conductive encapsulation in a housing allows a good connection of this module.
- This housing offers two connections to the ground plane ranked in order of preference to ensure optimal connection:
