Abstract
The present invention provides a kind of solution for detecting the problem of instrument testing result is transient pulse, belongs to metallurgical automation control technology field.This method passes through the curve that iba checks detection instrument measured result first, if it find that measured object exists for a long time but instrument only detects an instantaneous pulse, then increases to the power supply capacity of detection instrument power supply.Using this method, electrical personnel are by checking iba curve, and replacement can be quickly by troubleshooting to the power supply of detection instrument power supply, downtime caused by reducing because of failure.
Description
Technical field
The present invention relates to metallurgical automation control technology field, particularly relating to a kind of detection instrument testing result is instantaneous arteries and veins
The solution for the problem of rushing.
Background technique
Some hot rolling mills will appear once in a while some detection instrument under certain conditions testing result be pulse the problem of, than
Such as, roughing exports pyrometer, and when rolling non-extreme trace time, pyrometer testing result is normal, but when rolling extreme trace time, Ben Ying
Milling train, which stings steel occiput arrival pyrometer to roughing mill extreme trace secondary dish out, can detect always slab this period, but practical high temperature
Meter only detects a pulse, influences second level to finish rolling and issues setting data, to influence normal production.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of solutions for detecting the problem of instrument testing result is transient pulse
Certainly method.
It is as follows that the method comprising the steps of:
(1) curve of detection instrument measured result is checked by iba；
(2) time that confirmation measured object is placed in the measurement point of the detection instrument is greater than the pulse letter that the N times of instrument detects
Number time；
(3) by the way that the power supply to detection instrument power supply is changed in the power supply settlement steps to deal (2) of 2 times of former power supply capacity
Problem.
Further, the detection instrument is one of pyrometer, hot metal detector or cold metal detector.
Further, the method that the confirmation measured object is placed in the time of the measurement point of detection instrument is moved using measured object
The length of dynamic speed and measured object calculates measured object by the time needed for the detection instrument, or checks and the detector
Epitope set the measurement result of other similar detecting elements and the movement speed confirmation measured object of measured object and meanwhile be located at this two
The time of a detection instrument.
Further, the N >=1000.
The advantageous effects of the above technical solutions of the present invention are as follows:
In above scheme, electrical personnel by checking iba curve, replacement to detection instrument power supply power supply can quickly by
Troubleshooting, downtime caused by reducing because of failure.
Detailed description of the invention
Fig. 1 is to illustrate that detection instrument testing result of the invention is instantaneous arteries and veins in the embodiment of the present invention by taking pyrometer as an example
The measured result curve synoptic diagram for the problem of rushing.
Specific embodiment
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
The present invention provides a kind of solution for detecting the problem of instrument testing result is transient pulse.
It is as follows that the method comprising the steps of:
(1) curve of detection instrument measured result is checked by iba；
(2) time that confirmation measured object is placed in the measurement point of the detection instrument is greater than the pulse letter that the N times of instrument detects
Number time；
(3) by the way that the power supply to detection instrument power supply is changed in the power supply settlement steps to deal (2) of 2 times of former power supply capacity
Problem.
In a particular application, this method is firstly the need of the history curve for checking detection instrument testing result, if measured object
The time of the measurement point of the detection instrument is placed in much larger than the time for the pulse signal that the instrument detects, this method can be used,
It is increased to the power supply capacity of detection instrument power supply.
As shown in Figure 1, pyrometer is identical with heat inspection installation site after machine after roughing mill by taking pyrometer as an example, heat inspection detection
As a result normal, but the testing result of pyrometer is rolling non-extreme trace time Shi Zhengchang, when rolling extreme trace is secondary, pyrometer is only detected
One pulse solves above-mentioned pyrometer by increasing the power supply capacity powered to pyrometer as a result, and only detects in extreme trace time
To the problem of a pulse.
This method has been successfully applied to the detection instrument issue handling of multiple hot rolling mills, the favorable comment by user.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, several improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
