The utility model discloses a gas control device based on a Profibus (process field bus) platform, which comprises a microprocessor connected with a sampling signal sensor, an electromagnetic valve and a Profibus special chip respectively. The Profibus special chip is provided with a communication interface conforming to a Profibus standard, adopts isolated RS485 physical layer design, supports Profibus protocol and adopts a knob switch for setting product addresses. The gas control device is capable of functioning in remote control, support of online fault diagnosis, flow accumulation and the like by the aid of the Profibus protocol.
Description
Technical field
The utility model relates to a kind of digital flow control system, relates in particular to a kind of gas control equipment based on the Profibus platform.
Background technology
Flow measurement and control are very important parts in the industrial circle.Flowmeter in the market can be divided into gas flow controller and liquid flow controller.Flow controller can be used for accurately measuring and control the flow by this equipment.
Flow control system of the prior art adopts simulated mode usually, and needs corresponding power supply of outfit and display instrument are observed the variation with Control Flow, and Control Flow is directly perceived inadequately like this, is unfavorable for operated from a distance, can not satisfies high level requirement.
Also have the flow control system of part to adopt the serial digital communication, for example adopt communication modes based on RS232 or RS485 standard, these modes can realize basic communication function, but communication speed is lower, poor reliability, often adopted master slave mode etc., the reliability aspect still has bigger gap during large-scale application.
The utility model content
