Process safety emergency protection system and method for large ship lock with high water head

Abstract

A high water head large-scale ship lock process safety emergency protection system and method, which is a system and method that can independently realize the key process safety emergency protection of the ship lock in addition to the protection function of the normal operation control of the ship lock, focusing on the lock protection and closing detection of the ship lock , High-head ship lock dynamic water closing valve and other process safety protection functions, which can effectively reduce the work intensity of operators, resist network security risks, and improve the safety of ship lock operation. By configuring the system, the redundant protection function with the control system can be realized. The principle is simple, the implementation is convenient, the effect is remarkable, and it has the advantages of double protection, emergency intervention, strong compatibility and high reliability.

Description

technical field [0001] The invention belongs to the technical field of ship lock control and monitoring, and in particular relates to a system for safety monitoring and emergency protection of key processes of ship lock operation and a method for using the same. Background technique [0002] According to relevant statistics, there are more than a thousand ship locks in the country. With the development of the industry, the demand for deep integration of ship lock operation management and control technology is increasing, and the data exchange between the operation control system and the information service system will be inevitable. The design concept and application technology of the traditional ship lock industrial control system can no longer fully cope with the increasingly severe network security risks. [0003] In addition, the existing ship lock control system is generally composed of PLC, computer and various sensing and actuator equipment. The ship lock operator op...

The design concept and application technology of the traditional ship lock industrial control system can no longer fully cope with the increasingly severe network security risks

[0003] In addition, the existing ship lock control system is generally composed of PLC, computer and various sensing and actuator equipment. The ship lock operator operates the gate / valve opening and closing according to the normal operation process of the ship lock, and the equipment status monitoring and fault automatic monitoring are carried out by collecting signals from the sensors. However, when the sensor abnormality or other reasons cause misjudgment of the key safety process signal during the operation of the lock, the control system cannot reliably realize the automatic emergency protection function, especially the emergency protection of the key process safety during the water delivery process of the high head ship lock. Operators are highly dependent, resulting in high work pressure for operators
