The synchronizing technology,data storing technology,the technology of coordinated start of record- collecting units and communicating technology are key technologies to a recording system . A synchronizing method adapted to the distributed fault recording system is proposed which consists of synchronizing the sampling pulses of various record- collecting units by m eans of the pulse signals per second of GPS followed by the synchronization of the sequence of sam pled values by adopting the software auto- synchronizing algorithm.The method of starting the record- collecting unit and the effect of such a starting method on the data collecting window are discussed.It can be seen from analysis thatthe adoption of the distributed storage for recorded data can solve the problem of insufficient storing capacity of the concentrated fault recording system and the pressing time for retransm ission.It is proposed that the TCP/ IP- based network com munication should be adopted as the mode of com munication between the m aster recording station and record- collecting units. Presented in this paper are the construction of the IP addressing distributed fault- recording system and conclusions about dynam ic analog tests on a prototype.
