Fault detection and location in data networks - using software based system to examine response signals within predetermined time

摘要

The procedure for fault detection and location in data network depends upon the examination of received signals after each `normal` transmission. If not state charge indication is received within a pre-determined period of time, a fault condition is assumed. Pref. the data communication network may be based in a vehicle comprising a network (1), a serial bus (2), with attached circuit (3). The circuit (3) includes control interfaces (4) for a vehicle, a CPU (5), bus interfaces (6), an interface management processor, (7). In control register (8) and a station register (9). In the absence of a received signal at least one further attempt/transmission is made. USE/ADVANTAGE - Controller area networks esp. vehicles; software programmable system.
