Electromagnetic flowmeter system based on Internet of Things and control circuit

Abstract

The invention discloses an electromagnetic flowmeter system and control circuit based on the Internet of Things, and the system comprises a power module, an electromagnetic flow sensor, an electromagnetic flow conversion control unit, and an Internet of Things module, and the electromagnetic flow conversion control unit is connected with the power module, the electromagnetic flow sensor, and the Internet of Things module. The electromagnetic flow sensor converts a flow signal of a measured fluid into a corresponding standard voltage signal and transmits the standard voltage signal to the electromagnetic flow conversion control unit for processing, and the processed data is communicated with the PC through the Internet of Things module. Accurate measurement of fluid flow velocity is realized by adopting a double-controller mode of the single-chip microcomputer and the CPLD, the system has the advantages of high precision, high adaptability, high data real-time performance and the like,remote monitoring and management of the electromagnetic flowmeter can be realized by utilizing the function of the Internet of Things, fault information of the electromagnetic flowmeter is reasonablyand effectively analyzed, the reliability analysis efficiency is improved.
