摘要:
A method for monitoring the quality of a communication channel supported by a sliding contact, the method comprising the following steps: controlling (401) the application of a continuous electrical signal onto one of the elements of the sliding contact, receiving (402) a plurality of values (V(n)) of electrical signals measured on the other of the elements of the sliding contact, estimating (408) from said plurality of measured values, a variance parameter value, comparing (409) the variance parameter value with a threshold (THR) and, on the basis of the result of the comparison, generating a signal (CHANNEL_OK, CHANNEL_NOK) representative of the quality of the communication channel.
摘要:
The invention relates to a system for transmitting signals (106), including a device (601) for transmitting data between a movable portion and a stationary portion of a windmill, to be installed on the mobile portion or the stationary portion of the windmill, and including: connection means (603, 603') for connecting at least one wireline to a plurality of groups, in order to receive a plurality of respective data flows, each flow coming from a corresponding apparatus installed on the mobile portion or on the stationary portion of the windmill; means (604) for processing the received streams, configured such as to assign a priority parameter value to each received stream, and in the event of concomitant reception of multiple streams, to compare the values of the priority parameter that are associated with the received streams and transmit by priority to a module for transceiving the radiofrequency signals, with a view to a radiofrequency transmission to the other of mobile portion or the stationary portion of the windmill, the stream associated with the value of the priority parameter corresponding to the highest degree of priority.
