摘要： PURPOSE:To acquire systematic knowledge by generating the conclusion part of rules based on the contents of manual interposing operations, generating the condition part of rules based on plural facility signals obtained from opera tional facilities and lining the condition part and the conclusion part. CONSTITUTION:In an automatic blowing system using a controller 104, a scheduled operational value required for facility control is written in a scheduled value file 301 by an operational plan processing 201 and read by an operational facility control processing 202, and a controlled variable signal (a) is outputted to a suitable operating facility 101. A facility signal (b) from the operating facility 101 is received by a facility signal management processing 203 and written n a result value file 303. When any operational action is inputted to the controller 104 as an operation control panel signal (c) in the case of any abnormal operation, that signal is received by the facility signal management processing 203, and the control processing 202 is activated. The controlled variable signal (a) intended by the operation control panel signal is outputted to the operating facility 101 by the operating facility control processing 202.

摘要： PURPOSE:To perform mill speed control not changing a speed of a 1st stand by making the 1st stand a pivot stand and supplying a successive control amount obtained by correcting a speed of an (i)th stand to a control means for an (i+1)th and later stands. CONSTITUTION:A mass flow standard of a tandem hot strip mill 3 is determined that in the No.1 stand by making the No.1 stand as a pivot stand. A speed of the No.1 stand is kept constant so that AGC or successive control performed in a manual speed control mode are conducted for later stands than the No.1 stand as the No.1 stand is a standard. Therefore, speed synchronization between a continuous casting machine 1 and the mill 3 is easily performed and variations in tension on the inlet side of the mill 3 are prevented. At a time of changing a speed of some stand to deal with tension variance in the mill 3, a control preventing mass flow variation and not changing a speed of a 1st stand on the inlet side of the mill 3 is performed to keep a balance between the mill 3 and the casting machine 1.

摘要： PURPOSE:To perform speed reduction in the shortest time when abnormality occurs, by giving a function calculating a speed reducing rate in accordance with the load torque of each rolling stand to a speed reduction controller. CONSTITUTION:When, for example, a trouble occurs in a coiler which is the outlet side facility of a rolling mill, an emergency signal S26 is outputted from a speed commanding circuit 73 to a speed control circuit 72. From the circuit 72 a speed command signal S1 which commands the shortest speed reduction in accordance with a speed reducing rate signal S14 determined at an optimum rate determining circuit 71 is outputted to drive controllers 21-26. Namely, when, for example, rolling stands 1-6 are operated at speeds V1-V6 and an emergency stop is applied at the time T0 under a normal condition as shown in the figure, each stand 1-6 selects the maximum value tdec4 among speed reducing and stopping times tdec1-tdc4 and stops in accordance with the selected speed reducing and stopping time tdec4, while each stand has the speed reducing and stopping times tdec1-tdec4 in accordance with load torque values. AS a result, the speed of each stand is reduced in the shortest time while they maintain the same speeds at the time of emergency and bad influences to the material and facility can be suppressed to the minimum.

摘要： PURPOSE:To improve the plate thickness accuracy at the front and rear ends by obtaining a rolling load deviation of the rolled stock rear end at the (n-2) path for the final (n) path and correcting a rolling load at the (n-1) path by adding a predicted thickness deviation at the (n) path to the rolling load. CONSTITUTION:A reversible rolling mill having a servo valve 4 is provided with a load cell 10, draft position detector 2, and pulse generator 20. A rolling pressure detected by the cell 10 is compared with the set target value at the (n-2) path to obtain a deviation DELTAP to store the DELTAP in a shift register 22 and a setup computer 24 calculates a correction amount at the (n-1) path. Then, a correction amount at the final (n) path is obtained through an arithmetic circuit 23 and the above two correction amounts are added to a rolling load at the (n-1) path to correct the rolling load. In that method, plate thickness deviations of the front and rear ends are corrected at the one less path, so that the thickness accuracy at the front and rear ends is improved.

摘要： PURPOSE:To prevent continuation of runaway of a program and to prevent an erroneous output by providing a function for monitoring whether a branch destination is registered or not, in case when an instruction is executed as a nonsequential instruction. CONSTITUTION:In case when a branch or an interruption is generated at the time of memory fetch from a CPU, the fetch sequence becomes discontinuous. A branch destination and an execution start destination in case of an interruption are written in advance in an association memory 51. In case when contents of an address bus 101 at the time of fetch coincide with an address written in advance, a signal 512 is applied as a load signal 513 to a counter 52 through an output gate 57. Also, in case when a value of the counter 52 does not coincide with the address 101 at the time of fetch, it is shown that abnormality is generated in the CPU, therefore, a strobe signal 502 to a memory is inhibited by a gate 58. At the same time, an error signal 503 is generated, and the CPU starts processing for abnormality.
