Novel intelligent coal conveying control system based on FCS on-site bus technology

Abstract

The invention provides a novel intelligent coal conveying control system based on the FCS on-site bus technology. The novel intelligent coal conveying control system based on the FCS on-site bus technology comprises a coal unloading system, a digital coal filed control system, a coal feeding system, a silo mixed coal blending combustion control system and a sub-system. The purposes of reducing labor and increasing efficiency are realized for a thermal power plant. Through intelligent coal combustion management, the heat value difference loss of as-fired coal caused by management loopholes is reduced. Through the automatic selection of system processes and routes, energy increase caused by operation habits of operators is reduced, and the additionally increased fuel cost is effectively reduced. Unattended operation of a coal conveying site is realized, the labor intensity of coal conveying workers is largely relieved, and the work environment is improved. The FCS on-site bus technology has the advantages of reducing the hardware number and investment, saving installation expenses, saving maintenance expenses, realizing high system integration initiative of users, improving accuracy and reliability of the system and the like, and truly realizes a full-distribution type system with concentrated information and disperse control.

Description

technical field [0001] The invention belongs to the technical field of production scheduling of thermal power plants, and in particular relates to a novel intelligent coal handling control system based on FCS field bus technology. Background technique [0002] According to incomplete statistics, the fuel cost of the current thermal power plant has accounted for more than 70% of the operating cost of the power plant, and the operating cost of the fuel system has become the main factor related to the economic benefits of the power plant. The level of automatic control and fuel management of the system is an important means to save costs, reduce staff and increase efficiency, and it is a problem that many domestic thermal power plants need to further solve. [0003] The coal handling system of the power plant has the characteristics of complicated operating equipment, long operating time, heavy work tasks, high labor intensity of operating personnel, poor operating environm...

However, these functions can only be completed by a single module, and there is no connection between functions. Moreover, from the perspective of the overall process of the coal transportation system, there are still quite a few systems that do not participate in the control, such as the management of vehicles for incoming coal, truck scales, and truck unloading coal. , dumper unloading coal, sample collection, bucket wheel machine, silo mixed coal, point
