Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, a data storage device capable of collecting flow of a flow meter in real time includes an upper computer control system 1, a flow meter 2, a flow data collector 3 and a fault alarm 4.
As shown in FIG. 1, the flowmeter 2 is connected in series to a pipe where a flow is to be detected, the flowmeter 2 is preferably an electromagnetic flowmeter, a transmitter of the electromagnetic flowmeter has a simple structure, has no movable parts, and has no throttling parts for obstructing the flow of the fluid, so that no additional pressure loss is caused when the fluid passes through, and at the same time, the transmitter does not cause problems such as abrasion and blockage, the electromagnetic flowmeter has no mechanical inertia, is sensitive in response, has an extremely wide range of measurement, can measure instantaneous pulsating flow, and has good linearity, so that a measurement signal can be directly converted into a standard signal output linearly by a converter, can be indicated on the spot, and can be transmitted remotely, and the electromagnetic flowmeter is a volume flow measuring instrument which is not influenced by the temperature, viscosity, density and conductivity (within a certain range) of a medium to be measured during measurement, therefore, the electromagnetic flowmeter can be used for measuring the flow of other conductive liquids only after water calibration, does not need to be additionally corrected, can truly and accurately reflect the real-time change condition of the flow in the pipeline, can carry out different numbers on the flowmeters 2 in different pipelines, and is convenient for rapidly knowing which pipeline flowmeter 2 fails in the follow-up process.
As shown in fig. 1, the flow data collector 3 is connected with the flow meter 2 by wireless signals, and the flow data collector 3 is electrically connected with the upper computer control system 1 through the serial server 5, wherein the serial server 5 is used as a communication bridge between the upper computer control system 1 and the flow data collector 3, the upper computer control system 1 is connected with the serial server 5 by a network cable, the plurality of serial servers 5 are respectively connected with the upper computer control system 1, the serial server 5 is powered by DC24V, a power supply mode of AC220V to DC24V is collected in the power distribution control cabinet, when the flow data in the pipeline is detected by the flow meter 2, the flow data is transmitted to the flow data collector 3 by wireless mode for storage and recording, and the flow data collector 3 collects and stores the flow data in real time, which is convenient for monitoring the staff of the upper computer control system 1 to master the change situation of the flow in the pipeline anytime and anywhere, and the upper computer control system 1 can regularly request real-time flow data information in the pipeline from the flow data collector 3 through a Modbus protocol, and the mode can be a Modbus _ TCP mode: the port of the server is 502, the default configuration of the IP address is 192.168.0.2, and the Modbus _ RTU mode can be: the device address is 1, the virtual serial port number defaults to COM1, the above specific parameters can be modified according to the actual situation, and the two modes both adopt a 03 function code mode to read the flow data with 2 bits corresponding to the holding register in the flow data collector 3.
In the two communication modes, the flow data collector 3 and the upper computer control system 1 perform real-time query on the flow data, and reliable communication is performed in a request/response mode, and the communication flow is as follows: the upper computer control system 1 sends a request query command to the flow data collector 3 at regular time, the flow data collector 3 judges the received information, and the collected flow data in the pipeline is returned to the upper computer control system 1 under the condition that the data verification is correct; in the case of a check error, the received data is discarded and a negative acknowledgement is issued.
As shown in attached figure 1, the fault alarm 4 is electrically connected with the upper computer control system 1, when the upper computer control system 1 receives a correct response, the flow of the pipeline is calibrated at a specified time point according to the flow data in the pipeline, and then the flow data of each pipeline forms an independent function diagram according to a real-time flow calibration value, so that the actual flow in the pipeline can be acquired and stored in real time, and the flow change in the pipeline can be intuitively known according to the linear change in the function diagram so as to quickly respond The maintenance improves the timeliness and accuracy of the inspection and the maintenance, and is convenient for better protecting the pipeline.
When the upper computer control system 1 does not receive the response information of the flow data collector 3, a retransmission mechanism is started, if the upper computer control system 1 does not receive the response information of the flow data collector 3 again, the communication circuit between the flow data collector 3 and the upper computer control system 1 is considered to be in fault, after the maintenance of workers is arranged to be completed in time, if the upper computer control system 1 receives correct response again, the communication circuit is completely faultless and can be continuously used, if the upper computer control system 1 receives negative response at the moment, the retransmission mechanism can be started again, if the upper computer control system 1 receives negative response, the flow meter 2 is considered to be in fault or the flow meter 2 is disconnected with the flow data collector 3, then reconnection is started between the flow meter 2 and the flow data collector 3, and if the reconnection is started for 1 minute, the updating of the flow data is not received, can judge the 2 trouble of flowmeter, owing to can not receive flow data in the function graph that this trouble communication circuit corresponds this moment, consequently its function graph linearity takes place huge change, and fault alarm 4 also can play by oneself and report to the police, and the staff of arranging of being convenient for in time quick maintains, has the characteristics of real-time collection, storage, automatic alarm.
The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
