Developing SCADA System based on Scientific Computation Software Scilab

OSSS-EA’2006

To Solve the Shortage of Traditional SCADA

We propose a method

The Design of SCADA System Based on Scilab

1. Costs, Scilab is free.

OSSS-EA’2006

Why choose Scilab? Not Matlab, etc.

2. Source, Scilab open its Code source, which allow us modify the software according to our opinion, or integrate Scilab to our own software.

3.Toolbox, Scilab provides much toolbox in control and optimization area.

4. OS, Scilab support Linux operating system.

The Key Technology

Realizing exchange data between factory and Scilab

What Should Do?

Developing Scilab Interface with Factory Device According to Some Industrial Protocol, Such as OPC, Field Bus, Industrial Ethernet, etc.

What we have done?

The OPC Foundation has established a set of standard OLE/COM interface protocols intended to foster greater interoperability between automation/control applications, field systems/devices, and business/office applications in the process control industry.

The Realization of Data Acquisition with Scilab-OPC

OPC interface

With OPC technology, we can acquisition data from different device easily.

And not need to know physical structure.

Acquisition Data

We also developed Modbus Protocol Interface, and Industrial Ethernet Protocol Interface.

They can let Scilab acquisitive data easily from device through Serial Port and Ethernet.

Also, to storage the data to database, we developed Mysql interface.

Conclusion

In the past, Scilab only can used in discrete and off-line control in laboratory. Through the SciSCADA toolbox, Scilab can exchange data with device layer and Ethernet layer convenience. It transforms Scilab from discrete and off-line control to continuous and on-line control.

OSSS-EA’2006

Conclusion

SciSCADA system is proposed based on Scilab.

It can …

Enhance the SCADA system’s scientific compute ability

Realizing control and optimization on-line
