Embodiment Construction
[0057] Figure 1a A first example of the architecture of a communication system for controlling and monitoring peripheral devices according to the invention is depicted.
[0058] The communication system according to the invention comprises a master communication module 100 connected to at least one slave communication module. exist Figure 1a In the example, the master communication module 100 is connected to multiple slave communication modules 120 1 to 120 N , where N is greater than 2.
[0059] Each communication module 120 1 to 120 N A port connected to the main communication module via a bidirectional link. The bi-directional link and the port are distinct from the respective ports and respective bi-directional links that connect the respective other slave communication modules to the master communication module 100 .
[0060] The bidirectional link is eg a 100Base-T Ethernet cable according to the ARINC 664 P2 standard and eg has a length of about 10 to 20 metres. ...

The present invention relates to a communication method and a communication system for controlling and monitoring at least one peripheral device, the system comprising a master communication module, the master communication module is connected to a slave communication module or each slave communication module, the slave communication module is far or not far from the master communication module, The or each slave communication module is arranged near the controlled peripheral device and connected to the port of the master communication module through a bidirectional link. The master communication module sends a data frame comprising the value of the counter, and each slave communication module reads the value of the counter included in the received data frame, updates the counter with the read value, checks whether the value of the updated counter corresponds to The time period index associated with the slave communication module, if yes, transmits the data frame to the master communication module. The master communication module selects a port coupling the master communication module to a slave communication module from a table including a time period index and an identifier, the identifier of the slave communication module being associated with the time period index corresponding to the value of the counter.
Description
technical field [0001] The invention relates to a communication method and system for controlling and monitoring at least one peripheral device in an aircraft. Background technique [0002] Traditionally, electronics for controlling and monitoring peripherals used in the braking system of an aircraft, such as for example power switches, static converters, actuators or electric motors, are located in the vicinity of the peripherals, for example. [0003] This proximity between the control and monitoring electronics and the peripherals ensures good reception of the control and monitoring signals and avoids any problems with any signal propagation time or loss of synchronization between distant or not-so-distant independent devices . [0004] Currently, there is a need for a centralization of the control and monitoring electronics that minimizes loss of synchronization and is robust to any loss of synchronization between the control and monitoring electronics and electronics p...
