SPL-F Control System has the following functions: data collection, control, alarm, graphic demonstration and data demonstration
Product Introduction:
SPL-F control system is composed of three parts: weigh belt feeder, electrical control system and computer management system. The system adopts the versatile human- industrial computer interaction interface and modern configuration software. It has the following functions: data collection, control, alarm, graphic demonstration and data demonstration etc. It can not only work independently on the spot, but also can be connected to DCS to realize remote centralized control. It is applicable to metallurgy industry, mine industry, cement industry and chemical industry, where needs quantitative feeding control, and where various materials will be quantitatively fed according to proper mixture ratio. Its weighing capacity is correct, stable and reliable.
Optional measuring equipments: WFL/M/S weigh belt feeder, FB-NJG pressure-resistant gravimetric coal feeder, FB-JGC full-closed gravimetric coal feeder and FB-WCF circulating fluidized bed combustion gravimetric coal feeder.
Main Functions and Features:
Operating Mode:
Automatic mode: choose the presetting formula on IPC and then startup system after the formula is confirmed. Dosing system can control weigh feeder automatically according to presetting formula.
Semi-auto or manual mode: manually set the proportion of formula on the controller, and manually start up the controller to control VFD and weighing feeder for feeding.
Data collection and control of dosing system
The system collects the data in digital quantity mode from field device and realizes monitor and control function by operating real-time data and offers real-time data base to help monitor the production process.
The system provides equipment screen that can display updated real-time data. At the same time, it provides one big screen that can show the whole operation process to make you observe the whole technical production process easily. The data displayed includes operation mode, flow rate, total accumulation, setting point, deviation, and other similar data. The display screen of dosing system simulates the front operation board and allows the operator to monitor and control the remote instrument in control room.
Data and history record: (data log, measuring accumulation, flow rate, material position and/or other related data)
System data recorder collects the data from the equipment and keeps running accumulation and event log. The data log reserves current and history data and can run continuously and provide inquiry at any time. Statistics tab provides the chart and the alarm function based on real-time data treatment, so operator can monitor and regulate the whole production process.
Visualized Interface
The control system also has the visualized interface to make the applied system easy to develop and maintain. Some special properties and displayed feature can be chosen through extension list and placed on the screen. The data defined by the user can be displayed on the screen immediately that is to say what you see is what you get.
Alarm Control and Management:
Make continuous monitoring on production process and alarm in time for the potential problems. Users can define the demanded upper and lower limits by alarm configuration. The alarm information can be obtained by screen, printer, E-mail and other modes and forms alarming documents to be stored in data base, and the operation information will be recorded automatically. The operation display of feeding scale control system provides rapid and intuitive analyzing tool for production process. By this, operator can confirm, analyze and adjust alarm quickly and carry out the required process regulating control operation, and can directly monitor and control equipment according to the display on the computer.
Historical Trend:
Historical trend chart can display the changing data history record.; the history records and the tendency display functions provided by this control system can carry out offline data analysis. The historical trend display function can display all kinds of tend with curves, and can show the dynamic relationship between different variables. The history document formed by the history data can also be output to other management program for the detailed further analysis.
