Network cable transmission gives manager distant place background computer.
6. it is according to claim 5 it is a kind of possess on-line monitoring and the device of off-line test breaker function, its feature exists
In 8 tunnel intake interfaces wherein four interfaces through four signal output parts of a PS2801 types optocoupler, four signal input parts, and
On/off switch state on vacuum circuit breaker, experiment/operation working condition, a distant place/state, test point status port pass through signal on the spot
Line connects, and 8 tunnel intake interface four additional interfaces are defeated through four signal output parts of another PS2801 types optocoupler, four signals
Enter end, and on vacuum circuit breaker on the spot conjunction state, isloation state, distant place conjunction state, distant place isloation state port pass through signal wire on the spot
After connection, FPGA module can gather each on-off model simultaneously, and on-off model transmits after PS2801 type optocoupler Phototube Couplings
To FPGA module, FPGA module passes through parallel bus, by the data-signal high-speed transfer of collection to one-chip computer module, single-chip microcomputer mould
Block passes through network by the data transfer of collection to core control panel again, and core control panel is stored, calculates, leads to data after analysis
An interface in network optical port and network power port on sensor board is crossed, manager distant place background computer is given through network cable transmission,
Distant place background computer can monitor and test breaker on/off switch state, experiment/operation working condition, a distant place/state, survey on the spot
Pilot state, on the spot conjunction state, on the spot isloation state, distant place conjunction state, distant place isloation state.
