Detailed Description
Referring to fig. 1, a preferred embodiment of a method for searching a string table position on a pipeline according to the present invention includes the following steps:
step S1, after a string of water meters is verified by any meter calibrating machine, the string of water meters is placed in a designated area on a production line, and meanwhile, triggering software reads the parameters of the water meters verified by the meter calibrating machine before triggering;
in step S1, the step of reading the water meter parameters verified by the meter corrector before triggering by the triggering software includes: and the triggering software reads the water meter parameters verified by the meter calibrating machine within 8-10 minutes before triggering. Because the time for the meter calibrating machine to calibrate the water meter of the whole string is about 6-8 minutes approximately, the read time is set to be 8-10 minutes before triggering in order to read the water meter parameters of the whole string of water meters conveniently. Of course, the time range set by the present invention is only used for obtaining the exact implementation effect, and in the specific implementation, the reading time can be changed according to the actual requirement.
In step S1, the read water meter parameters at least include a meter number, a flow error of three flow points (three flow points Q1-Q3), a start flow rate, and pressure test parameters. In the concrete implementation, other water meter parameters can be added according to the actual requirements.
In practical implementation, 3 meters are usually arranged on both sides of the pipeline, and their numbers are assumed to be A1-A3 and B1-B3, respectively, and each meter is correspondingly provided with a button for triggering software to read data. In the process of calibrating the meter, when a string of water meters (a string of water meters generally has 8 meters) is calibrated by the meter calibrating machine A1, the calibrated string of water meters is placed in a designated area on the production line, and a button of the meter calibrating machine A1 is pressed, so that the software can be triggered to read the parameters of the water meters calibrated by the meter calibrating machine before being triggered.
Step S2, storing the read water meter parameters to the specified position of the software, and simultaneously recording the time for triggering the software to read the water meter parameters and the stepping speed of the assembly line;
step S3, when re-checking, at least one water meter is randomly extracted from any appointed area on the production line, and the extracted water meter is placed into other meter checking machines for checking to obtain a checking result;
in step S3, the step of placing the extracted water meter into another meter calibrating machine for calibration to obtain a calibration result specifically includes:
before checking, firstly, a check code is input into other checking machines (for example, letter J is used as the check code) to trigger to enter a comparison and storage mode, then the number of the extracted water meter is input into the other checking machines, and the extracted water meter is placed into the other checking machines to be checked, so that a check result is obtained. The reason why the comparison and save mode is triggered is to avoid overwriting the previous data so as to facilitate the judgment of the verification result in the following.
Step S4, the software automatically judges whether the check result is in the qualified range value, if yes, the check result is stored to other appointed positions of the software, and the process is ended; if not, storing the check result in other specified positions of the software, controlling the pipeline to stop running, reading the stopping time of the pipeline, and then entering the step S5; in specific implementation, the qualified range value can be input by a checker according to actual requirements, when software automatically compares, flow errors, starting flow, pressure test parameters and the like of three flow points can be judged one by one, and when the flow errors of the flow points of Q1 do not fall within the set qualified range value, the stop line processing is controlled.
In step S4, when the control pipeline stops operating, the method further includes: and outputting an alarm to remind related personnel to process in time, and displaying the verification result which is not in the qualified range value to a centralized display screen.
And step S5, the software calculates the time difference according to the time for reading the parameters of the water meter and the stop time of the assembly line, calculates the walking distance of the assembly line according to the time difference and the stepping speed of the assembly line, and displays the position of the water meter to be rechecked on the assembly line according to the walking distance.
In summary, the invention has the following advantages: the method can effectively overcome the defect of the conventional mark placement, can quickly display the accurate position of the designated area of the water meter extracted from the assembly line, and is convenient for the calibration personnel to process in time.
Although specific embodiments of the invention have been described above, it will be understood by those skilled in the art that the specific embodiments described are illustrative only and are not limiting upon the scope of the invention, and that equivalent modifications and variations can be made by those skilled in the art without departing from the spirit of the invention, which is to be limited only by the appended claims.
