1995, And systems for recording and reading synchronised of deals from a plurality end of 2002

摘要

The present invention relates to the techniques of recording and replaying synchronized of data from a plurality of terminal equipment. Each terminal equipment (e1, e2, e3, e4 and e5, e6) emits datas on a communication line (l1, l2, l3, l4, l5, l6) which is clean. The transmission on this line may be a synchronous or asynchronous, in parallel or in series, according to any protocol not acknowledged. The recording system (s1) according to the invention comprises at least: (a) one or more routers (m1, m2) connected to the lines of communication, each communication line being connected to a router, in order to be sampled at a constant frequency signal (pdu1 ns) in each communication line, and this even in the absence of data transmitted, so as to each terminal corresponds to a bit flow sampled; (b) a local network (re), which are connected the routers, on which the routers emit the flows of bits sampled; (c) a central processing unit (uc) connected to the local network, to record in one or more binary files the flows of bits transmitted by the routers to said network. The present invention applies in particular to the tests of systems for managing the air traffic, the terminal equipments being in this application of the radar.
