AI Technical Summary

Technical Problem

In the Industrial Internet, the reading and writing speed of analog semaphores is relatively low, making it difficult to guarantee the timeliness of writing analog semaphores when there are a large number of concurrent requests. Existing technologies cannot effectively solve the problem of interference between read and write requests.

Method used

The reading and writing of analog semaphores are separated into different asynchronous message buffer queues. A configurable read-write load balancing algorithm is designed to utilize multiple concurrent read or write processes to achieve separation and load balancing of read and write requests, ensuring the timeliness of writing analog semaphores.

Benefits of technology

It enables timely writing of analog semaphores to the device under a large number of concurrent read and write requests, and ensures that read and write operations do not interfere with each other through a load balancing algorithm, thereby improving processing efficiency.
