The connection between modules is shown in fig. 1.
The production information input module is used for extracting production information from a production plan, specifically comprises the current batch of rolled steel processing length, the next batch of rolled steel production specification and the next batch of rolled steel processing length, and inputs the production information into the automatic number reporting system.
The number reporting management equipment setting module is used for setting a length detection terminal on a rolling mill roller way, and setting quality detection equipment and cutting equipment at a fixed position away from a processing port, wherein the quality detection equipment comprises quality detection trigger equipment and quality detection execution equipment, the quality detection trigger equipment is arranged on a roller way surface corresponding to the fixed position, and the quality detection execution equipment is arranged on a roller way side wall corresponding to the fixed position. In particular, the fixed position should be located on a central line along the length of the roller table.
The length detection terminal is an ultrasonic sensor, the quality detection triggering device is a photoelectric sensor, and the quality detection executing device is a high-definition camera.
It should be understood that the quality detection trigger device is arranged on the roller way surface corresponding to the fixed position to emit the photoelectric signal upwards by utilizing the quality detection trigger device, when the rolled steel is processed from the processing port, the processing length of the rolled steel reaches the distance between the processing port and the fixed position, and the rolled steel is arranged above the quality detection trigger device, the emission of the photoelectric signal is blocked, and signal interruption feedback is formed, so that the apparent quality detection of the rolled steel by the quality detection execution device can be triggered.
It is further understood that the provision of the quality inspection execution device on the roller side wall corresponding to the fixed position facilitates the acquisition of the apparent image of the rolled steel on the one hand, and on the other hand, in order to avoid the blocking of the quality inspection execution device by the longer and longer rolling process.
In a specific embodiment, the following procedure is followed for setting the length detection terminal on the rolling mill roller way: the length from the processing port to the roller way end point is obtained and recorded as the roller way length, the roller way length is divided according to a set distance interval to obtain a plurality of dividing points, a length detection terminal is arranged on the side wall of the roller way corresponding to each dividing point, and the length detection terminal is numbered according to the sequence from the near to the far from the processing port.
It is to be understood that the demarcation point should be located on a centerline along the length of the roller way.
Specifically, length detection terminals are arranged on the side walls of the roller tables corresponding to the dividing points, so that the problem that the length detection terminals are directly arranged on the dividing points to block the processing length of the steel rolling is avoided.
Preferably, the setting of the number management device is as shown in fig. 2.
According to the invention, the length detection terminals are arranged on the rolling mill roller way at intervals, so that the target length detection terminals are selected from a plurality of length detection terminals arranged at intervals based on the rolling mill processing length of the current production batch, and then the target length detection terminals are started to detect the rolling mill processing length, thereby realizing the targeted detection of the rolling mill processing length.
The apparent mass detection module is used for detecting the apparent mass of a rolled steel body from a processing port to a fixed position in real time by using mass detection equipment in the current batch of rolled steel production process, and the specific implementation process is as follows: and in the current batch of steel rolling processing process, the quality detection trigger equipment is utilized to transmit signals, feedback signal induction is carried out in real time, and when the feedback signal is induced, the quality detection execution equipment is started to acquire apparent images of the steel rolling bodies.
It is to be added that the steel rolling body refers to the steel rolling when the steel rolling length is processed from 0 to a fixed position, and the apparent mass detection is performed on the steel rolling body to ensure that the processed steel rolling is only subjected to the apparent mass detection under a certain length, so that the detection frequency is too high due to the fact that the apparent mass detection is performed under the condition that the steel rolling is too short in processing, and the apparent mass detection is more reasonable and the detection cost is reduced by controlling the detection frequency of the apparent mass.
Identifying whether an apparent defect exists in the apparent image of the steel rolling body, if so, marking a defect area in the apparent image of the steel rolling body, and extracting defect indications, including defect areas and defect types.
Applied to the above embodiments, defect types include, but are not limited to, scratches, curls, ginning, rust spots, pits, waves, and the like.
And matching the defect types with the degree influence factors corresponding to the various defect types stored in the cloud management library, and matching the degree influence factors corresponding to the defect areas.
The rolling body surface area is obtained by extracting the rolling body outline from the apparent image of the rolling body.
Passing the degree influence factor corresponding to the surface area and the defect area of the steel rolling body through an expressionAnd calculating the apparent mass coefficient of the steel rolling body, wherein the smaller the defect area corresponding to the defect area is, the smaller the degree influence factor is, and the larger the apparent mass coefficient is.
The steel rolling body cutting judging and processing module is used for cutting and judging based on the apparent quality detection result of the steel rolling body, if the steel rolling body is judged to need cutting, the cutting length is obtained, and the cutting equipment cuts according to the switching length.
As a preferred implementation mode of the scheme, the cutting judging mode is to compare the apparent mass detection result of the steel rolling body with the set up standard apparent mass coefficient, and if the apparent mass detection result of the steel rolling body is greater than or equal to the standard apparent mass coefficient, the cutting is not required, otherwise the cutting is required.
In particular, in the above apparent mass coefficient calculation formula, the apparent mass coefficient has a value range ofThe standard apparent mass coefficient may be set to 0.9.
Further preferably, the cut length is obtained as follows: the rolling body profile is extracted from the rolling body surface image, and the start line and the end line are marked from the rolling body profile.
And extracting the edge contour of the defect area from the defect area marked by the apparent image of the steel rolling body.
Constructing a line parallel to the initial line of the profile of the steel rolling body as a reference line, and translating the reference line to the edge profile of the defect area until the reference line is tangent to the edge profile of the defect area.
It should be noted that the start and end lines of the profile of the rolled steel body are relative to the process orifice, the closest start line to the process orifice.
The length between the reference line and the contour stop line of the rolled steel body is referred to as a cut length, as shown in fig. 3.
The automatic control module for the steel rolling processing number report is used for detecting the steel rolling length processing standard by utilizing the length detection terminal and automatically controlling the steel rolling processing number report according to the detection result.
In the example of the scheme, the steel rolling length processing standard reaching detection is carried out by utilizing the length detection terminal, and the following process is adopted: extracting the processing length of the current batch of rolled steel from the production information, and combining the processing length with the set distance interval through a formulaObtaining the number of the target length detection terminal>In the formula->The representation is rounded up and is filled up>Expressed as the current batch rolling length, +.>Represented as a set distance interval.
Calculating a demand detection distance of the target length detection terminal based on the number of the target length detection terminalThe calculation formula is +.>In the formula->Expressed as a distance between a set position of the target length detection terminal and a dividing point corresponding to the set position,/>The representation is rounded down.
It should be understood that, because the length detection terminal is disposed on the roller side wall corresponding to the dividing point, the setting position of the target length detection terminal, the dividing point corresponding to the setting position and the rolled steel processed by the processing port form a right triangle, as shown in fig. 4.
Starting a target length detection terminal to aim at a processing port in the current batch of steel rolling processing process to detect the distance between the setting position of the target length detection terminal and steel rolling from the processing port in real time as a detection distanceComparing the detection result with the required detection distance of the target length detection terminal, and using a standard model +.>Calculating the rolled steel length processing up to the scale->，/>Expressed as a natural constant, wherein the closer the detection distance is to the required detection distance, the greater the scale of the rolled steel length process.
The principle that the length detection terminal is utilized to carry out steel rolling processing length detection is that an ultrasonic signal is sent to a processing port through the length detection terminal, when processing is not started, the sent ultrasonic signal directly reaches the processing port, the ultrasonic signal is reflected back through the processing port, the measured length is the length from the processing port to the setting position of the length detection terminal, when processing is started, the ultrasonic wave sent by the length detection terminal cannot directly reach the processing port due to the fact that steel rolling comes out from the processing port, after the steel rolling is encountered, the ultrasonic wave is reflected back, and the measured length is the length from the steel rolling to the setting position of the length detection terminal.
In still another example of the above solution, the following operations are automatically controlled according to the detection result for the steel rolling process report: comparing the rolled steel length processing reaching scale with the set qualified processing reaching scale, and if the rolled steel length processing reaching scale is 0.8, extracting the next batch of rolled steel production specification from production information, generating a number reporting mark corresponding to the next batch of production specification by utilizing an automatic number reporting system, simultaneously conveying the next batch of rolled steel production specification to a rolling mill control center, automatically adjusting a rolling mill roll gap according to the next batch of rolled steel production specification, and if the rolled steel length processing reaching scale does not meet the set qualified processing reaching scale, continuing detecting distance and calculating the rolled steel length processing reaching scale until the rolled steel length processing reaching scale meets the set qualified processing reaching scale.
It should be noted that the steel rolling production specification switching is generally diameter switching, and the production specification switching can be achieved by adjusting the roll gap of the rolling mill to conform to the next batch of steel rolling production specification.
According to the invention, the length detection terminal, the quality detection equipment and the cutting equipment are arranged on the rolling mill roller way, and the production information is input, so that the quality detection equipment is utilized to detect the apparent quality of rolled steel in real time in the current batch of rolled steel production process, the cutting equipment is utilized to carry out cutting treatment according to the detection result, and then the length detection terminal is utilized to carry out rolled steel processing length detection in the process, so that the automatic number reporting system is utilized to carry out number identification generation and specification switching according to the detection result in combination with the production information, the combination of automatic number reporting and the appearance quality detection of rolled steel in the rolled steel processing process is realized, the rolled steel processing length obtained under the automatic number reporting control can meet the production requirement to the maximum extent, and the implementation value of automatic number reporting is greatly improved.
The steel rolling processing number reporting control indication acquisition module is used for dividing transition state steel rolling from next batch of produced steel rolling after the steel rolling processing number reporting automatic control, and acquiring number reporting control indications from the transition state steel rolling, wherein the specific acquisition process is as follows: and acquiring the length of the transition state rolled steel, carrying out image scanning on the transition state rolled steel, acquiring the profile of the transition state rolled steel, and further extracting a transition curve and a central line along the length direction from the profile.
And uniformly distributing a plurality of acquisition points on the transition curve, and making a vertical line to the central line along the length direction from each acquisition point, wherein the vertical line length corresponding to each acquisition point is obtained as shown in fig. 5, and the longest vertical line length, the shortest vertical line length and the median vertical line length are extracted from the vertical line length.
The longest vertical line length, the shortest vertical line length and the median vertical line length are led into a formulaAnd calculating the transition curve smoothness, wherein the shorter the difference between the length of the longest vertical line and the length of the shortest vertical line is, the larger the transition curve smoothness is.
And taking the length of the steel rolling in the transition state and the transition curve smoothness as sign control indications.
