基于令牌總線和工業(yè)以太網(wǎng)的控制系統(tǒng) Control System Based on Token Bus and Industrial Etherne

摘要:針對令牌總線控制系統(tǒng)中節(jié)點間數(shù)據(jù)的傳輸效率隨節(jié)點數(shù)量增加而降低的情況，采用FPGA技術(shù)結(jié)合工業(yè)以太網(wǎng)提出了一種滿足強實時要求的總線型控制系統(tǒng)。通過將整個系統(tǒng)劃分為若干個令牌總線型子網(wǎng)絡，再將子網(wǎng)絡通過工業(yè)以太網(wǎng)互聯(lián)的方法提高了整個系統(tǒng)的實時性。試驗結(jié)果表明節(jié)點間數(shù)據(jù)通信良好、實時性強，達到了預期效果。

Abstract: Aiming at the situation that the eficiency of data transmission between nodes in token bus control system decreases when the numbers of the nodes in the system increase, by combining the technologies of FPGA and industrial Ethernet, a bus-type control system which strongly meets real-time requirement is proposed. Through dividing the whole system into several token bus sub-networks, and linking the subnetworks by industrial Ethernet, the real-time performance of the whole system is enhanced. The test result shows that the data communication among nodes is wel with real-time performance and reaches predictive efects.
