This application discloses a multi-tenant task scheduling method and related apparatus, relating to the field of cloud computing technology. It receives tasks to be scheduled and their metadata, determines dynamic priority information, and sends the task to a target priority queue if the tenant corresponding to the task has an effective quota. When a tenant has a concurrent consumption token in the target priority queue, it acquires the token, executes the task, and then releases the token. This application sets different dynamic priorities for tasks to be scheduled, ensuring that tasks are distributed to resource-isolated independent queues, guaranteeing priority processing of each task, and improving resource utilization. Before task publication, sliding window rate limiting is implemented, and tenant-level concurrent consumption tokens are distributed during task consumption, isolating tasks between tenants. In complex multi-tenant, high-concurrency production scenarios, this enables intelligent task adjustment, significantly improving resource utilization and scheduling efficiency.

This utility model discloses a dual GNSS antenna cooperative positioning device for container loading and unloading operations. A first positioning antenna is positioned at the center of the lifting beam, and a second positioning antenna is positioned at the end of the lifting beam, allowing the positioning antennas to move with the lifting device. The distances from the first and second positioning antennas to the center of the lifting beam are configured differently. When the lifting beam lifts a container, the center of gravity detection component in the container overload / off-center load detection device generates rising or falling edge signals due to factors such as changes in the container's weight. This signal triggers the second positioning antenna, allowing the device to determine the container's specific location. When the lifting beam rotates, the position of the second positioning antenna relative to the first positioning antenna changes. Therefore, the positioning host can use the correspondence between the positions of the first and second positioning antennas and the container's center of gravity to obtain the container's position coordinates and center of gravity coordinates.
