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.
