AI Technical Summary

Technical Problem

Existing multi-gantry crane collaborative hoisting systems lack flexibility in synchronization strategies, lack a unified data sharing platform, struggle to respond quickly to changes, and have insufficient safety fault tolerance and redundancy mechanisms, making the system prone to interruption in the event of a single point of failure.

Method used

The system adopts a distributed shared memory architecture and an event-driven control mechanism. Real-time data exchange between multiple gantry cranes is achieved through the shared memory module. Combined with the central dispatch control module and safety monitoring module, data consistency and system reliability are ensured. Atomic read/write mechanism and redundant communication channels are used to improve the system's fault tolerance.

Benefits of technology

It enables efficient and precise coordinated control of multiple gantry cranes, reduces data transmission latency and jitter, improves system flexibility and safety, and can quickly switch to safety protection mode in case of failure, ensuring the reliability and stability of operation.

Abstract

The invention provides a collaborative operation real-time data exchange system and method suitable for a collaborative hoisting scene of multiple portal cranes, and relates to the field of portal crane control. The system comprises a gantry crane control unit, a shared memory module, a central scheduling control module, a safety monitoring module and a system database. According to the method, a shared memory with partitions and a communication link are established through initialization, instructions are issued through central scheduling when tasks are executed, state synchronization and autonomous fine adjustment of all the gantry cranes are achieved based on the shared memory, the data transmission amount is reduced by combining event driving and differential synchronization, and the safety monitoring module monitors in real time and triggers the fault-tolerant process. According to the scheme, the real-time performance, the safety and the expansibility of collaborative operation are improved, and the method is suitable for multi-machine collaborative hoisting in scenes such as large ports and wharfs.
