Monitoring system and monitoring method based on flow meter

Abstract

The invention discloses a monitoring system and a monitoring method based on a flow meter, relates to the technical field of flow meter monitoring, and comprises the monitoring system and the monitoring method. The monitoring system comprises a data acquisition module, an A / D converter, a transmitter, a central processing unit, a data comparison module, a data feedback module, a storage module, anexecution module and a display module. The monitoring method comprises the steps of instrument correction, safety range numerical value setting, data acquisition and transmission, data storage and comparison, and command execution. According to the monitoring system and the monitoring method based on the flow meter provided by the invention, through the monitoring system and the monitoring method, the numerical value of the flow can be monitored in real time, and the response under the safe or dangerous condition can be made according to the set numerical value of the safe flow area, so thatthe safety is greatly improved; and the monitoring under the long-distance unmanned state is realized, so that compared with the manual monitoring of the flow meter, the working intensity of workers is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of flowmeter monitoring, in particular to a flowmeter-based monitoring system and monitoring method. Background technique [0002] A flow meter is defined as: an instrument that indicates the measured flow rate and / or the total amount of fluid within a selected time interval. Simply put, it is an instrument used to measure the flow of fluid in a pipeline or open channel. Generally, in a large factory, in order to be able to detect the flow rate in each pipeline, a flowmeter is required for detection, and in order to ensure that the flow rate of each pipeline is at a safe value, it is necessary to monitor the flowmeter at all times. [0003] However, in the prior art, most monitoring methods are manual inspection and monitoring one by one, which will not only increase the labor intensity of the staff, but also fail to achieve the function of real-time monitoring of the flow value, making it impossible for the...
