It can be unrestricted according to engineering site screen cabinet installation site freely from conjunction.
Further, each sampling board does transparent forwarding to non-board sampled data message, reduces forwarding transmission and prolongs
When；Board is sampled according to the period of setting, the sampled data message of this board is sent into looped network；In the sampled data received
In message, the sampled data message of this board is directly abandoned, is not forwarded.
Further, each sampling receives the synchronous sampling board MAC Address for allowing to send message in looped network of board, each
Sampling receives board and configures its received sampling board MAC Address of needs.
Further, the MAC Address list to E-Packet is configured by receiving in board in sampling, to inhibit unrelated message
It circulates in looped network；Sampling is mutually in step sampling board MAC Address between receiving board, and all sampling board MAC Address is made to exist
Sampling receives in board forwarding list；Sampling receiver board is stuck in the sampling board sampled data message that can not receive its needs
When, periodically send sampling board MAC logon message to looped network, other sampling plates are stuck in receive message after by board MAC
Address is added in forwarding list, realizes that all sampling board forwarding lists are synchronous, so that sampling receives the sampling that board needs
Data message circulates in looped network.
Further, the sampling receives board forwarding and handles the sampled data message received while carrying out, and reduction is adopted
Sample card E-Packets delay；It samples receiver board clamping and receives the sampling board data message that the board needs, reduce sampling and receive
Board load factor.
Further, the sampling receives board to sampling board clock synchronization, and samples receiver board card and pass through setting sampling plate
Moment occurs for card sampling, and each sampling board is made to realize synchronized sampling.
Further, sampling receiver board card snaps into the path delay of sampling board by calculating sampling receiver board, and amendment is adopted
Sample receives the clock synchronization moment that board is sent to sampling board, realizes accurate clock synchronization；Sampling receives board according to reality in sampling system
Border needs to send sampling instant to sampling board, realizes the sample-synchronous of all sampling boards of sampling system.
Sampling system may specify that a sampling receives board as clock synchronization source, send clock synchronization request to sampling board.Sampling
It receives board and the delay of board message interaction is received according to sampling board and sampling, calculate the road that sampling receiver board snaps into sampling board
Diameter delay, and the clock synchronization moment that board is sent to sampling board is received according to delay constantly amendment sampling, to guarantee all adopt
Sample card and sampling receive board time synchronization.
The beneficial effects of the present invention are:
1, sampling board is cascaded with sampling receiver board card by optical fiber head and the tail in the present invention, forms bidirectional loop network,
