Description
Technical Field
The invention relates to the field of electrical control, in particular to a method and a system for detecting the deviation degree of a rolling mill thickness gauge and a computer medium.
Background
In the production process of the cold-rolled strip steel reversible rolling mill, because of the requirement of strip steel thickness control, the automatic thickness control AGC must use a thickness gauge to measure the thickness of the strip steel in real time and send the information such as thickness deviation to a master control PLC to carry out thickness adjustment and related control.
The existing thickness gauge can provide key data for each control link of the master control PLC on line. However, whether the measurement data of the thickness gauge is accurate or not cannot be judged in time by an operator in the production process. If the deviation degree of the thickness gauge exceeds the allowable deviation range, the actual thickness of the rolled strip steel is inconsistent with the set thickness, and the product quality accident is caused.
Therefore, there is a need for a method and system for obtaining deviation of a thickness gauge in real time and timely reminding the deviation exceeding the allowable deviation range.

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth to illustrate, but are not to be construed to limit the scope of the invention.

and S06, calculating a deviation value between the downstream second flow thickness calculation value and the downstream strip steel thickness measurement value, and obtaining the deviation degree of the downstream thickness gauge according to the ratio of the deviation value to the downstream strip steel thickness measurement value.
As shown in fig. 3, further the deviation value is calculated by the following moving average method, including:
s061, taking the preset length of the strip steel as a unit length, collecting downstream strip steel thickness measurement values of a plurality of time points in the unit length, wherein intervals among the time points are equal;
s062, combining the upstream strip steel speed measurement value and the downstream strip steel speed measurement value of each time point, and calculating the second flow thickness calculation value of the downstream strip steel of the time point;

Further, the plurality of time points are 5 time points, and the unit length is 5 meters.
As shown in fig. 2, the further calculation formula of the second flow thickness calculation value of the downstream strip steel is as follows:
The calculation is based on the principle of conservation of material flow at upstream and downstream of the rolling mill, and the downstream second flow thickness calculation value can be calculated according to the principle through the upstream and downstream strip steel speed measurement values and the upstream strip steel thickness measurement value.
The speed measurement values of the upstream and downstream strip steel are obtained in real time through the rotating speeds of the left and right steering rollers and the coiling machines and the coiling diameters of the left and right coiling machines, and further the linear speeds of the strip steel rolled by the coiling machines, namely the speed measurement values of the upstream and downstream strip steel are obtained. The upstream strip thickness measurement value is determined by a left or right thickness gauge (according to the different turning directions) and the working noise of the thickness gauge.
Furthermore, the upstream thickness gauge and the downstream thickness gauge are arranged symmetrically, when the rolling direction of the strip steel is changed, the original upstream thickness gauge is changed into a new downstream thickness gauge, the original downstream thickness gauge is changed into a new upstream thickness gauge, and the calculation process of the deviation degree of the new downstream thickness gauge is the same as that of the original downstream thickness gauge. As shown in fig. 2 and 5, the turning roll, the coiler and the thickness gauge are arranged in a left-right manner, when the rolling direction is from left to right, the left side is upstream, and the right side is downstream, otherwise, the left side is downstream, and the right side is upstream. Taking the linear speeds of the left and right recoiling machines and the left and right steering rollers as the linear speed measurement value of upstream or downstream strip steel according to the rolling direction, tracking the thickness detection point of an upstream thickness gauge to a roll gap according to the speed to obtain the thickness measurement value of the upstream strip steel, calculating the thickness of the strip steel at the roll gap outlet by utilizing the upstream and downstream material flow conservation principle of the cold rolling mill, namely calculating the second flow thickness calculation value of the downstream strip steel,
as shown in fig. 4, the further method further comprises generating an alarm trigger signal when the deviation degree is greater than 2%, and triggering a thickness gauge alarm to alarm.
The alarm of the upstream thickness gauge and the alarm of the downstream thickness gauge can use the same alarm, and the same alarm generates different alarm sounds when receiving trigger signals of different thickness gauges with out-of-range deviation degrees. Or the alarm of the upstream thickness gauge and the alarm of the downstream thickness gauge are different and correspond to the upstream thickness gauge and the downstream thickness gauge one by one, and the technical scheme of the invention is not limited by the above.
Furthermore, the thickness gauge alarm is controlled by a Programmable Logic Controller (PLC), and related operation and setting are completed through a human-machine interface (HMI).
According to the embodiment, the alarm threshold is set, namely, the trigger signal is generated when the deviation degree is greater than 2%, and the alarm is triggered to alarm, so that the deviation degree of the thickness gauge is automatically monitored, and an operator can timely adjust the thickness gauge.
And further, all deviation values and corresponding deviation degrees generated by the thickness gauge on the same steel coil where the strip steel is located serve as the same group of data to be associated with the ID information of the steel coil and then stored in a database, and the method is used for tracking and counting the measurement deviation conditions of different steel coil thicknesses.
In the embodiment, the deviation value and the deviation degree of the same steel coil are stored in the database after being associated with the ID information of the steel coil as the same group of data, so that the tracking and the statistics of the thickness measurement deviation values of different steel coils can be realized, and the reference can be provided for the thickness monitoring in the subsequent rolling of other steel coils.

and the deviation degree calculation module 5 is used for obtaining the deviation degree of the downstream thickness gauge according to the ratio of the downstream strip steel thickness measurement deviation value to the downstream strip steel thickness measurement value.
