AI Technical Summary
In the current technology, waste oil collection points are numerous and scattered, relying on platform scales and manual single-bucket measurement, which is inefficient, has large errors, and is poorly managed, making it impossible to achieve real-time, accurate, and segmented oil weight measurement.
The device employs segmented, precise, and intelligent monitoring of the weight of grease transported by vehicles. It includes a housing, a control module, a high-precision pressure sensor module, a Beidou positioning module, a vision perception module, and a communication module. Combined with electronic fence technology, it monitors the location and weight changes of grease transport vehicles in real time and captures evidence of loading and unloading status through the vision module.
It enables segmented metering and identification of oil transport vehicles, automatically acquires billing data such as loading weight, unloading weight, and unloading balance, improves metering accuracy and efficiency, and helps enterprises achieve refined management and cost reduction and efficiency improvement.
