AI Technical Summary

Technical Problem

The existing multi-stage lock control system is difficult to achieve real-time data acquisition, centralized control and communication control during ship lock passes, resulting in complex operations and heavy loads, and the problem that the operator station cannot take over control rights in the event of communication failure.

Method used

The double-ring network multi-level lock site control system is adopted, and the two I/O servers are hot backup for each other for data collection and instruction issuance, realizing multi-level uplink, downlink and water replenishment operations of the lock, and setting up a redundant PLC system and touch screen in the centralized control unit to ensure communication control with the gate site.

Benefits of technology

The automatic control of five-level uplink, downlink and water replenishment operations of the ship lock is realized, which reduces the load of the operator station, ensures the safety and reliability of the system, and allows the operator to manually take over the control rights in the event of communication failure.

Abstract

A double-loop network multi-stage ship lock on-site control system and method, which includes a centralized monitoring system connected to the on-site control system; multiple lockhead on-site stations of the on-site control system are connected to the double-loop network; the centralized control unit, IO server and engineer station of the centralized monitoring system are connected to the double-loop network; the two I / O servers between the on-site control system and the centralized monitoring system are mutually hot-standby, and perform data acquisition and command issuance to realize the ship lock's five-level up, five-level down, five-level water replenishment up, five-level water replenishment down, four-level up, four-level down, group synchronous lock passing, step-by-step continuous lock passing, manual lock passing, as well as emergency shutdown and emergency valve closing, reduce the load of the operator station, and at the same time, the operator station and the I / O server cooperate to complete the ship lock monitoring. The real-time process data collection, centralized control, operation and other functions of the single-line ship lock continuous lock passing operation are completed, and the communication control between the on-site control station is responsible.
