System and method for calculating flow

Abstract

The invention relates to a flow computing system and a flow computing method, wherein the flow computing system comprises an analog-to-digital convert device, as the data collecting interface between the flow computing system and the measured quantity; a flow computing device, including a processor, a program memory arranged with a flow computing module and an communicating interface for data communication with the analog-to-digital convert device, wherein the flow computing module furthermore includes a hardware driving module, a local data collecting module, a data processing and operating module, a system flow controlling module and a data storing module. The flow computing system has the following functions: reading the measuring signals of the flow, the pressure, the temperature and the like transmitted by the one-time measuring device; performing the analog-to-digital conversion on the obtained one-time measured signals and performing the data display and the data storage; configuring the different output signals of the one-time device through the hardware and the software, to satisfy the measuring requirement, with agile system expandability.

Description

technical field [0001] The invention relates to a flow calculation system for secondary processing of high-precision flow measurement. The flow calculation system can be widely used in petroleum, petrochemical, chemical, metallurgy, electric power, light industry, medicine, city gas, heating and other industries Flow measurement, energy measurement and the establishment of measurement data network, especially suitable for trade measurement, precious medium measurement occasions. Background technique [0002] For flow measurement, it generally consists of a primary detection element, a transmitter and a secondary display instrument. The function of the secondary instrument is to calculate the flow rate according to the standard signal output by the transmitter, corresponding to different types of detection devices, there are different specific calculation methods. If the detection devices are different, different secondary instruments need to be selected. Such secondary inst...

Problems solved by technology

In order to collect data reliably and in real time, the backbone network built by the enterprise for informatization construction should be fully utilized. However, none of the current secondary meters has an Ethernet network interface and does not support the Internet protocol (some even have no serial communication interface). To achieve collection, communication equipment must be added. On the one hand, it communicates with the secondary meter to collect data through serial communication. On the other hand, it connects to Ethernet to transmit data.
