[0002] As of 2024, the market holding capacity of aerial work platforms in China has broken through 600,000 units, showing a vigorous development trend of continuously expanding industry scale and increasingly rich application scenarios. However, in the actual use process of scissor-type aerial work platforms, there is still a realistic problem of low dispatching efficiency: there is currently no effective automatic calling system, which makes it difficult for workers to quickly locate the target device when facing dozens or even hundreds of scissor lifts in a single work scenario or a centralized parking yard.

[0003] Specifically, in the existing mode, whether searching for a specific scissor lift among many devices through manual methods or operating personnel walking from the work point to the device parking position and then driving the device back to the work point involves a lot of unnecessary time consumption and manpower investment, and the overall process is cumbersome and inefficient. This pain point not only reduces the on-site operation response speed, but also to some extent affects the project progress and equipment utilization. SUMMARY
