Problems solved by technology

Due to the physical characteristics of the analog signal itself, there is loss in the long-distance transmission process, and there are many on-site control cables, complicated laying, and the system cannot be diagnosed online.
In addition, the existing method of using 4--20mA current signal as a remote control signal can only realize the transmission of a single variable, so the transmission of multiple signal variables requires multiple pairs of cables

Abstract

The invention relates to a full-digital remote automatic test system for an electric actuating mechanism. The system comprises a Foundation Fieldbus, a bus power supply which supplies power and a bus controller cooperating with the Foundation Fieldbus; and the bus power supply, a guard grating and the bus controller are connected with the Foundation Fieldbus, the bus controller is connected with a host computer, and the Foundation Fieldbus is further connected with bus interfaces for testing the Foundation Fieldbus type electric actuating mechanism. The full-digital remote automatic test system is compact in structure, high in automatic degree and safe and reliable, can test the electric actuating mechanism remotely, and improves the test efficiency.

Description

technical field [0001] The invention relates to a test system, in particular to an all-digital remote electric actuator automatic test system, which belongs to the technical field of automatic test. Background technique [0002] As an electric drive device used in the field of fluid process control, the electric actuator is widely used in petroleum, chemical, power station, sewage treatment and other industries due to its use of AC motor control technology and remote signal automatic control technology. [0003] At present, a large number of domestic valve electric devices adopt traditional analog control methods, that is, the remote 4-20mA current loop or 1-5V voltage signal is used as the remote control signal, and the conventional DCS control system controls the action of the electric actuator by outputting a 4-20mA current loop, and The physical position output of the valve opening connected with the valve electric device is collected in real time to realize the control ...
