Abstract
The invention discloses an intelligent anti-leakage electromagnetic flowmeter and a control method thereof. The intelligent anti-leakage electromagnetic flowmeter comprises a data acquisition end, a preprocessing unit, a data memory, a control chip, a comparator and an alarming device, wherein the data acquisition end is connected with the preprocessing unit which is connected with the data memory; the data memory, the comparator and the alarming device are connected to the control chip; and the comparator is connected with the alarming device. The intelligent anti-leakage electromagnetic flowmeter automatically stores flow data sampling frequency set by a user, acquires flow data in real time, performs data analysis and preprocessing on the acquired data and stores the processed data into a real-time database of the system. The control chip forecasts leakage according to real-time data and a set deviation range, so that application requirements of the chemical industry, sewage treatment and special industries having severe pollutions and the like are met; therefore, the blank of the conventional anti-leakage flowmeters in China is filled.
Description
Technical field
Patent of the present invention relates to a kind of electromagnetic flowmeter, and is a kind of specifically through intelligent converter analysis, the continuous data on flows of processing, sends the electromagnetic flowmeter of leakage alarm in real time.
Background technology
Function that domestic all electromagnetic flowmeters do not possess at present has anti-leak (Realtime Alerts when the pipeline generation is leaked).For some special industries, like industries such as chemical industry, wastewater treatments, in a single day the leakage meeting takes place production safety, Environmental security is produced great harm in process pipe.Therefore, can in time report to the police to pipe leakage and just seem extremely important.The leak prevention system of this project product just is being based on this practical application request and is developing.
Summary of the invention
What patent of the present invention designed is a kind of intelligent anti-leak electromagnetic flowmeter, solves existing electromagnetic flowmeter and can not when pipeline takes place to leak, find situation and the problem of reporting to the police.
The objective of the invention is to realize through following technical scheme.
Intelligence anti-leak electromagnetic flowmeter; Comprise data acquisition end, pretreatment unit, data-carrier store, control chip, comparer and warning device; Said data acquisition end is connected with pretreatment unit, and said pretreatment unit is connected with data-carrier store, and data-carrier store, comparer and warning device are connected to control chip; Said comparer is connected with said warning device, and said comparer is connected to the data acquisition end simultaneously.
The control method of intelligence anti-leak electromagnetic flowmeter; Comprise: the data acquisition end can carry out a data acquisition at set intervals; The data on flows SF of data acquisition end is set by control chip, and the data of data acquisition end collection are through sending after the analyzing and processing of pretreatment unit and being stored in the data-carrier store the repeatedly image data of storing in the data-carrier store; And superpose by control chip and to draw the mean value in a period of time after calculating; Give the reference data of comparer with this mean value assignment simultaneously, and the data that the data acquisition end is gathered are in real time issued comparer, and compare with mean value as comparer; If error surpasses setting value, control chip can be controlled warning device and report to the police.
Intelligent anti-leak battery flowmeter provided by the invention is stored the data on flows SF that the user sets automatically, gathers data on flows in real time, after image data is carried out data analysis and pre-service, deposits the real-time data base of system in.Control chip predicts whether leak according to the deviation range of these real time datas and setting, and the application requirements that has satisfied chemical industry, wastewater treatment and had the special industry of harm such as serious pollution has been filled up domestic blank on the anti-leak flowmeter at present.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the modular structure figure of intelligent anti-leak electromagnetic flowmeter according to the invention.
Fig. 2 is the control flow chart of intelligent anti-leak electromagnetic flowmeter according to the invention.
Embodiment
As shown in Figure 1; Intelligent anti-leak electromagnetic flowmeter of the present invention comprises data acquisition end, pretreatment unit, data-carrier store, control chip, comparer and warning device, and said data acquisition end is connected with pretreatment unit; Said pretreatment unit is connected with data-carrier store; Data-carrier store, comparer and warning device are connected to control chip, and said comparer is connected with said warning device, and said comparer is connected to the data acquisition end simultaneously.
As shown in Figure 2; The control method of intelligence anti-leak electromagnetic flowmeter, comprising: the data acquisition end can carry out a data acquisition at set intervals, and the data on flows SF of data acquisition end is set by control chip; The data of data acquisition end collection are through sending after the analyzing and processing of pretreatment unit and being stored in the data-carrier store; The repeatedly image data of storing in the data-carrier store, and superpose by control chip and to draw the mean value in a period of time after calculating, the reference data of comparer given with this mean value assignment simultaneously as comparer; And the data that the data acquisition end is gathered are in real time issued comparer; And compare with mean value, if error surpasses setting value, control chip can be controlled warning device and report to the police.
Intelligent anti-leak battery flowmeter provided by the invention is stored the data on flows SF that the user sets automatically, gathers data on flows in real time, after image data is carried out data analysis and pre-service, deposits the real-time data base of system in.Control chip predicts whether leak according to the deviation range of these real time datas and setting, and the application requirements that has satisfied chemical industry, wastewater treatment and had the special industry of harm such as serious pollution has been filled up domestic blank on the anti-leak flowmeter at present.
The maximum FLASH data capacity of continuous 3 hours flow operational data is gathered and stored to leak prevention system of the present invention in real time.The user can set a traffic sampling time interval according to actual needs.After setting finished sampling time interval, the flow data storage was gathered in EEPROM in real time according to the SF that the user sets by system.Then, continuous renewal is kept at 3 hours operational data among the EEPROM, just preserves nearest 3 hours work on the spot data all the time.System is according to 3 hours up-to-date data, the data on flows that evaluation prediction is real-time, and then whether analysis conduit exists the situation of leakage to take place.
The mean value of 3 hours real time datas is got according to current 3 hours real-time traffic data by system, and deviation range can be set through the button on the working interface of electromagnetic flowmeter by the user at the scene, also can set at the Long-distance Control port.Such as setting in negative 10% the scope of mean value that deviation is 3 hour datas before this; If exceeding this scope system can think to exist and leak to take place; GPRS module through being integrated in the converter the inside is carried out SMS alarm; Through the telecommunication port, this information is presented on the interface of DCS system.
