The Operations and functions of our System, are divided in 2 subsystem, named Load Management and Process Control-Supervision.
The Management subsystem, establishes a relationship between external world (suppliers, service stations, ultimate customers) and the loading process on Plant, providing to Control Subsystem the data that shape the diferent operations in order to obtain, at the end, the results and emiting enclosing pappers.Their principal functions are: maintenance of general data base in the System, generation of requests and Loading orders, manual and automatic tracking of the Loading sequence, printing of enclosing documents, management of incidences, control of movements and product stocks, as well as, a whole of utilities of general purpose to management of users, global operations with files, parameter configuration, historical file of events and helps through help-windows on line.
The Control Subsystem, manages all the loading physical process, fitting it through the data recieved from Management Subsystem. Among their functions are included both the automated control of electropump, and other field equipments, and the supervision process by synoptic on screen, lists of alarm detection signals, loading management by dialoge man-machine (driver-ACCULOAD). On Islets of a Loading Point, recording of the loaded amount with its three magnitudes: gross volume at loading temperature, Net volume at reference temperature (15°C or 60°C) and equivalent weight, as well as the watch over generated data during the Load with continnous chek of comunications between all elements that form the System.
Also this Subsystem includes the display of data-state in Product Storage tanks and the monitoring with remote actioning of valves. At the same way, it can realize vigilance tasks and intrusism detection into the Plant and/ or Loading Terminal through videosensor automatic cameras of and/or high power with display on synoptic-screen of the diferent guarded zones, representation of detected alarms and other utilities such as: zoom, focusing of cameras, programed movement, video recording in alarm situations, and telecontrol from distant places (Central headquarters and others).
Both Subsystems with all functions above mentioned, are supported by a whole of equipments and integrate computer applications.
The Operation Safety and operative character of System, are extensively guaranteed by equipment of redundant configuration used and so the flexibility and exchangebility of work-stations and aplicantions.
