Abstract

The invention discloses an intelligent multi-loop electro-pneumatic valve positioner system which is composed of an upper supervisory system and a 16-loop positioning control system. The upper supervisory system comprises an STM32 embedded system and a touch screen; the STM32 embedded system adopts a modular design and comprises an embedded core board, a communication module, a power supply module, an AD acquisition module and an SD card recording module; the STM32 embedded system is in communication connection with the touch screen through an RS232 serial port bus; the upper supervisory system collects real-time data of a planned data collection point, sends the data to the touch screen according to a communication protocol, counts information and system state related data, and stores the data in the SD card recording module. The system has the advantages of being strong in communication function, high in intelligent level and the like, positioning operation and management of the intelligent multi-loop electro-pneumatic valve based on the field bus can be achieved, field parameter setting is simplified, control quality is improved, and networked design based on a field bus network architecture mode can be achieved.

Description

technical field [0001] The invention relates to the field of electric valve positioners, in particular to an intelligent multi-loop electric valve positioning system based on field bus. Background technique [0002] In recent years, with the development of industrial production and science and technology, there are more and more demands for intelligent electric valve positioners, especially for the upgrade of traditional mechanical positioners. The level of sophistication is getting higher and higher. The traditional mechanical positioner does not have a microprocessor, does not have intelligent conditions, and cannot realize relevant intelligent calculations. Compared with the traditional mechanical positioner, the intelligent multi-circuit electric valve positioner has unique advantages such as flexible structure, quick configuration, convenient use, modularization, strong function, expandability, and upgradeability, and has become the current intelligent electric valve p...
