Description
Technical field
The utility model relates to calibration equipment, specifically is a kind of flowmeter automatic check device.
Background technology
For the accurate metering of dependable flow instrument, most of flowmeters all need carry out verification before dispatching from the factory.Traditional verification work is undertaken by artificial and assisting of computing machine fully, but in the process of verification, all needs the operation of verification personnel tracking control of full process, not only take time and effort, and checking precision is difficult to guarantee.This in addition method of calibration is difficult to carry out the single-point correction in case check results is made mistakes, thereby has to verification again.Verification efficient manually lowly make it can't satisfy current fast pace, high efficiency production requirement.
The utility model content
The technical matters that the utility model will solve provides a kind of flowmeter automatic check device, solves the problem of existing flowmeter verification operation trouble, checking precision difference.
The technical scheme of the utility model is:
A kind of flowmeter automatic check device; Comprise the standard scale and the calibrated meter that are arranged on the pipeline; Described flowmeter automatic check device also includes the blower fan that is communicated with the pipeline that is provided with standard scale; The frequency converter that is connected with blower fan, switch board that is connected with frequency converter, standard scale and calibrated meter and the industrial computer that is connected with switch board.
Described be provided with the pipeline of standard scale and be provided with between the pipeline of calibrated meter be connected with first surge tank; Be provided with second surge tank between described pipeline that is provided with standard scale and the blower fan.
Described standard scale is a plurality of, is arranged at respectively on the pipeline of different tube diameters, and is provided with valve on the pipeline of different tube diameters.
Described valve is selected butterfly valve for use.
The advantage of the utility model:
The utility model is simple in structure, verification operation is convenient; Adopt industrial computer to accomplish verification work; Time saving and energy saving; Guaranteeing that checking precision requires can improve verification efficient greatly under the prerequisite, what have more advantage is can in software, merge fuzzy Judgment, self check from technology such as error correction, disposal of Redundancy, improves the intellectuality and the reliability of check system.

Embodiment
See Fig. 1; A kind of flowmeter automatic check device; Comprise that three are arranged at three standard scales 1 on the different tube diameters pipeline respectively, be arranged at the calibrated meter 2 on the air delivering pipeline, the blower fan 3 that is communicated with three pipelines that are provided with standard scale 1; The frequency converter 4 that is connected with blower fan 3 is with frequency converter 4, three switch boards 5 that standard scale 1 is connected with calibrated meter 2 and the industrial computer 6 that is connected with switch board 5; Three are provided with the pipeline of standard scale 1 and are provided with to be connected with between 2 pipelines of calibrated meter between pipeline and the blower fan 3 that 7, three of first surge tanks are provided with standard scale 1 and are provided with second surge tank 8, are provided with on the pipeline of standard scale 1 and are provided with butterfly valve 9.
See Fig. 2; Frame is sent by industrial computer 6, at first arrives the control module of switch board 5, and control module is accomplished the regeneration and the recovery of signal; And select correct communication line according to the destination address of signal, have only the slave unit identical just can receive data with destination address.In checking procedure, break down, connection line is carried out fault detect and location one by one through Hub.After self check was passed through during verification, industrial computer 6 was operated in the suitable frequency range it with frequency converter 4 communications earlier, reads the data of standard scale 1 and calibrated meter 2 then, and calibrated meter 2 is preserved and write to useful data, verifies the verification effect at last.
See Fig. 3, the processing flow chart of the utility model under self diagnostic mode.When industrial computer 6 when certain checkpoint continuous several times is read irrational data, program can automatically switch to diagnostic mode.Under this pattern, program can read the parameter in each place that possibly go wrong, and matees with standard form.At each checkpoint, the switching of valve, the frequency of operation of frequency converter, the parameter setting of instrument all is known.The method of pattern-recognition in the utilization Intelligent Information Processing, with the current state parameter of obtaining respectively with template in parameter mate, it is wrong if difference is then judged.It is wrong or the frequency converter output frequency is made mistakes or the setting of instrument parameter is not right to judge valve operation according to matching result, and various possible combination.Be that the place of makeing mistakes is revised at last, program back-checking pattern then.When making template, earlier the state parameter of each checkpoint is encoded, then the coding of all checkpoints is formed code table.When breaking down, be that index is tabled look-up, accomplish coupling fast, in time diagnose the place of ging wrong with the checkpoint.
See Fig. 4, the workflow of the utility model is:
(1), start software, prepare to carry out verification;
(2), start communication: communication modes can be selected RS485, USB, TCP/IP
(3), self check before the verification: main check valve close situation and communication link have no abnormal, if wrong information will be pointed out;
(4), carry out verification: at the checkpoint of each different in flow rate, read the data of standard scale and calibrated meter respectively, software can be sent out newer command to frequency converter when checkpoint whenever switched to next putting, and treated that the flow field begins reading of data after stable;
(5), data write: the data that obtain in the checking procedure are write calibrated meter;
(6), result verification: choose certain test point, read the flow value of standard scale and the flow value of calibrated meter, judge the effect after the calibration through error of calculation rate;
(7), report generation: after verification is accomplished, generate Excel data sheet form automatically to preserve significant data;
(8), quit a program: after all verification work were accomplished, software withdrawed from.
