Apparatus and Method for Generating Integrated Quality Information of the Strip in Single Process Line}

The present invention relates to a data collection method occurring in an instrument in an intermittent process.

The measuring instrument used in the rolling, annealing and correction process of the steel industry transmits data generated from the measuring instrument to a higher process computer (P / C) 200 through Ethernet communication.

The higher process computer 200 generates quality measurement data using the data received from the instrument.

In the intermittent steps of rolling, annealing, and correcting, a plurality of measuring instrument positions are different from each other, and a difference occurs in time for measuring the same position of the raw materials.

PLC 100 according to an embodiment of the present invention is a measurement data conversion unit 110, entry material length tracking calculation unit 120, exit material length tracking calculation unit 130, process information extraction unit 140, data management unit 150 and the data transmission unit 160.

The measurement data conversion unit 110 processes the analog signal generated by each measuring device in the intermittent process and converts the analog signal into a digital signal. In other words, the measurement data conversion unit 110 receives measurement data on the material generated by each measuring device in the intermittent process.

The entrance material length tracking calculation unit 120 generates a trigger signal whenever the material supply length becomes 1M and 5M using two pulse generators (PLGs) installed at the entrance side of the intermittent process.

The exiting material length tracking calculation unit 130 generates a trigger signal whenever the material extraction length becomes 1M and 5M using two PLGs installed at the exit.

The process information extracting unit 140 generates a material tracking reset due to the characteristics of the intermittent process, and thus, whether the tracking of the material is started or not, is the end of the material for generating the last tracking information of the material. A cut signal of the outgoing shear is generated to reflect the signal to be judged and the length that changes when the sample is extracted.

The data manager 150 generates a trigger signal corresponding to a process situation through the entry material length tracking calculator 120, the exit material length tracking calculator 130, and the process information extractor 140 to measure the measurement data converter 110. Data stored in the memory) is stored in the memory unit 155.

The data management unit 150 is a one-way open ring type queue (one-way open ring type queue) of the memory unit 155 in order to effectively integrate the data generated by the measurement data conversion unit 110 (data generated by the instrument). 155a).

As shown in FIG. 4, the one-way open ring type queue 155a is a data structure in which an existing ring type queue is modified to meet data tracking purposes.

A typical ring type queue is a front end pointer (155b) representing the first index of data, a rear end pointer (155c) representing the last index of data, and a storage space for storing data. Is done.

In the ring type queue, data is inserted at the position indicated by the front and pointer 155b when data is generated, and data is extracted at the position indicated by the rear and pointer 155c when the data is extracted.

On the other hand, even if the data is full in the storage space, the one-way open ring type queue 155a deletes the last data and stores the new data when new data is generated.

An advantage of the one-way open ring type queue 155a is that the program can be simplified and data positioning accuracy can be improved by not separately managing the front and rear processes of the start and end of the material in the intermittent process.

The one-way open ring type queue 155a selects the size of the storage space in consideration of the position of the instrument, and the part cut off by the front and rear processing of the start and end of the material is automatically disappeared by the one-way open characteristic. do.

The data manager 150 is composed of a set of one-way open ring type queues 155a and stores data by assigning a queue 1: 1 for each of the instruments belonging to the measurement data converter 110. The size of a queue is a parameter that must be set when assigning a queue to an instrument. It means the amount of storage space in the queue and represents the distance between the instrument and the point where data should be extracted.

The data manager 150 extracts the measurement data from the memory unit 155 and transmits the measured data to the data transmitter 160 when the trigger signal is generated by the exit material length tracking calculator 130.

The data transmission unit 160 collects information in units of 1M and when 5M is generated, the data transmission unit 160 is transferred to the upper process computer 200 and transferred to the upper database.

The data moved to the upper database can be freely extracted using the queue and can be used as a good data for judging the quality of the material.

The measurement data converting unit 110 receives the measurement data for the material generated by each measuring device of the intermittent process and transmits the measurement data to the data management unit 150 (S100).

When the trigger signal is generated each time the material supply length becomes 1M and 5M from the entrance material length tracking calculation unit 120, the data manager 150 stores the measurement data received by the measurement data converter 110 in the memory unit 155. Store in (S102).

When the trigger signal is generated each time the material extraction length is 1M and 5M from the exit material length tracking calculation unit 130, the data manager 150 extracts the measurement data stored in the memory unit 155 and transmits the data to the data transmission unit 160. To transmit (S104).

The data transmission unit 160 receives and stores measurement data from the data management unit 150, and transmits the measured data to the upper process computer 200 when the material length is 5M, in units of 1M (S106).
