Loading operations are very frequent in refineries, chemical plants, and some small and medium-sized oil depots. Improving loading speed, accuracy, and safety, as well as preventing phenomena such as tank overflow and static grounding, has always been an important factor affecting loading operations. According to local safety supervision regulations, interlocking control is gradually implemented for loading and unloading vehicles, and data is uploaded in real-time to the backend monitoring system. On the basis of analyzing the loading needs of petrochemical enterprises and summarizing advanced experiences and lessons at home and abroad, the SNKP quantitative loading system has been developed, which can meet the quantitative loading needs of various small crane tube trucks and trains.

The system consists of an on-site control section and a remote management section. The on-site control section uses the SNKP quantitative loading control instrument to collect and control the on-site instruments, while the remote management section uses an industrial computer for centralized management. The two parts are connected through the RS485 bus to form a distributed quantitative loading system. Operators can set parameters, operate and monitor on site, and can also concentrate on remote monitoring and management in the dispatch room, achieving integrated control.

The system has a reasonable structure and complete functions, including invoicing, sales, picking up, loading to delivery, accounting, and reporting. Each link can have corresponding functional support; The system automatically alarms for errors and records operations, which can effectively prevent accidents and prevent human cheating in operations, making operations and management more comprehensive.
