- the PCMCIA card includes a control unit 153 programmed to allow or prohibit a wireless connection being established by the communication unit 152. In other words, under certain conditions, the control unit 153 makes it possible to inhibit the transmitter of the communication unit 152.
- control unit 153 receives at least one flight data from the ACMS system. It is necessary, for security reasons, to confirm by several information the authorization of transmission.
- the communication unit 152 includes a processor programmed to manage the transfer of the flight data. Such management is the recovery of the flight data of the storage unit and a triggering of the transfer.
- the PCMCIA card is used to transfer flight data after an ACMS report is generated.
- Such an ACMS report is generated after at least one predetermined condition is verified.
- the ACMS report is generated after the aircraft has landed.
- conditions to be verified may be: the opening of the doors of the aircraft, a zero speed of the aircraft, a zero fuel flow, etc. All these conditions are configurable.
- This ACMS report includes among other things a certain number of information: the location of the aircraft, the date, the flight number, the serial number of the aircraft. This information is configurable.
- the ACMS report makes it possible to know a set of information at each landing of the aircraft.
- the storage unit 151 also includes a set of configuration data. This configuration data makes it possible to define a flight data transfer policy as well as parameters for the actual transfer of the flight data.
- This configuration data is for example:
- this generated report the communication unit detects the generation of this ACMS report. Such detection is followed by a comparison of the information contained in the ACMS report with the configuration data.
- the result of the comparison is mainly a decision on the automatic triggering of the transfer of flight data to the ground station.
- a comparison is for example, if at least one piece of information in the ACMS report is identical to a configuration data item (for example the aircraft is in an airport in which the data must be unloaded) the processor of the communication unit will unload automatically flight data in accordance with the configuration data.
- a configuration data item for example the aircraft is in an airport in which the data must be unloaded
- Another comparison may be to compare an inclusive (“logical AND”) or exclusive (“logical OR”) combination of ACMS report information against the configuration data.
- the processor will initialize the unloading of the flight data based on configuration data: choice of wireless network, compression ratio etc.
- the communication unit 152 can receive, via the wireless network 30, a request to trigger the transfer of the flight data.
- This request makes it possible to trigger the transfer of the flight data independently of the automatic unloading and may comprise transfer initialization data, for example to recover a certain type of data even if it is not provided in the configuration data stored in the data store. the storage unit.
- Triggering offloading on request ensures that flight data can be retrieved. It overcomes, for example, a human error in the creation of the configuration data. It allows more recovery Exceptional passing comparison of ACMS reports and configuration data previously described.
- Such a request can be, in the case of a cellular network, an SMS parameterized under certain conditions.
- the unloading of the flight data is only possible if the communication control unit has not inhibited the transmitter of the communication unit.
- the PCMCIA card comprises a unit 154 for managing the access to the storage unit 151, on the one hand by the processor of the communication unit 152 and on the other hand the ACMS system through the PCMCIA controller 155.
- the PCMCIA card includes a PCMCIA controller 155 for interfacing the ACMS system with the components of the PCMCIA card.
- the management unit 154 is connected to the ACMS system via the controller 155 PCMCIA.
- the connection between the management unit 154 and the controller 155 PCMCIA is performed by means of a standard "ATA" connection bus (for "Advanced Technology Attachatty”). It should be noted that this standard connection bus says “ ATA “is also known as” IDE “for” Integrated Drive Electronics. “It is also an ATA bus that connects the storage unit 151 to the management unit 154 on the one hand and to the unit 152 of communication on the other hand.
- the accesses to the storage unit 151 comply with the standard
- the unit 151 for managing the access to the storage unit 151 makes it possible to manage the access conflicts between the ACMS system and the processor of the communication unit 152.
- the access management unit 154 makes it possible to parallelize the reading and the writing of the storage unit 151. Indeed, the access management unit 154 will allow both the communication unit 152 to read the data present in the storage unit 151 without disturbing the writes by the ACMS system, writing that arrives via the PCMCIA controller 155. Indeed, in the case where, simultaneously, a write request from the PCMCIA controller 155, and a read request by the transmission unit 151, the access management unit 154, will issue and will sequence both commands, giving priority to the PCMCIA 155 controller.
- the management unit performs a context restoration of the ATA registers in the storage unit.
- ATA registers are saved and restored each time the master switches to the storage unit, the master being alternately the processor of the communication unit 152 or the ACMS system through the PCMCIA controller 155.
- registers are as follows (from the ATA standard): Feature, Sector Count, Sector Number, Cylinder Low, High Cylinder, Drive / Head, Command and Device Control.
- registers correspond to the address, type of access (read / write), that the ACMS system through the PCMCIA controller 155 or the processor of the communication unit 152 wishes to do on the storage unit.
- the ACMS system and the processor of the communication unit 152 would be obliged to provide this information before each access to put the storage unit back in the context. of the current master. To do this, a modification of the software of the ACMS and the processor of the unit 152 is essential. Otherwise the errors would be:
