The Design Of Boiler Water Treatment Based On The CAN Bus Control System

The boiler is one kind of production steam or the hot water heat change equipment, widely applies in the Thermal power plant and the Industrial enterprise, along with the industrial automation degree's unceasing enhancement, is also getting higher and higher to the boiler control system's request. In a sense, the boiler economical and safe operation have the pivotal function to the entire national economy.The boiler biography can medium raw material is the water. The boiler water quality, has the very tremendous influence to its safe operation and the energy consumption. When the boiler water does not gather the request, the boiler heating surface knot will live the boiler scale, will thus not only waste the massive fuels, will also be dangerous to the boiler, therefore it is more important to appeared to the boiler water treatment. At present also implements the manual control in our Country Overwhelming majority Enterprise's boiler water treatment production, the production technology is backward, the energy use factor is low, the staff labor intensity is big, the working conditions are bad, but the efficiency is very actually low, has not opened the full display energy potency, promotes the national economy rapidly expand, to realize the boiler water treatment production automatic control is inevitable tendency, therefore, designs set of securities, reliably, the effective control system to be imperative.This paper puts forward a fieldbus control system project in allusion to the steam boiler. This paper discusses software and hardware construction of boiler SHCAN2000 fieldbus, the design and realization of software and hardware in the course of practical application. Integrating boiler control computer reconstructing, the paper presents the solution of adopting SHCAN2000 system to realize auto control, including loop auto control, test data auto-collection, friendly human-machine interface, test reports auto building, etc. The function configuration realization of operation station and field control unit is discussed in this paper.This control system has successfully applied in Hengtai power area at Huludao. The system has strong function, good control effect, and generalize application value. This proves the scheme design properly and practically, which realizes boiler control by FCS. This paper makes valuable attempt for field-bus'further application on industry control field.
