摘要： PURPOSE:To prevent the malfunction of the dam control system by giving the periodical check to the gate opening and then locking the gate control part in case the variation amount of the gate opening exceeds continuously and twice the set value. CONSTITUTION:Outflow amount calculation part 4 calculates the outflow amount based on the gate opening and the data given from water level indicator 2; inflow amount calculation part 5 calculates the inflow amount based on the outflow amount and the water level change; and target discharge amount calculation part 6 calculates the target discharge amount based on the target water level and the inflow amount respectively. Based on the target discharge amount, the target opening of the gate is calculated at gate opening calculation part 7. Then gate 23 is operated via gate operation command part 8 and gate control unit 9. In such system of the fault detection, the output of gate opening meter 1 is sent to opening data comparison calculation part 3. And in case the opening deviation to the previous value exceeds continuously and twice the set value, alarm transmission device 11 displays the fault. At the same time, gate 23 is locked via gate control lock part 10.

摘要： PURPOSE:To monitor the mis-compounding when many kinds of raw materials are taken out from the raw tank such as in a sintering process etc., by means of utilizing that the bulk specific gravity of the raw material and the motor velocity use the weight of the raw material as a feedfback quantity. CONSTITUTION:The raw material in a raw material tank 1 is taken out by means of driving a motor 106, a supplying feeder 102, and a measuring feeder 103. The taken out weight is allowed the measured quantity by a belt scale 104 belonging to a measuring feeder 103 and a belt velocity to be operated by an analogue operator 105, and is calculated by means of counting the transported weight on the counting feeder. A control objetive value operator 101 is effected by a monitor controller 200. A control set value set by the operator 101 (a ton per a taken out weight per Hr. T/H) is inputted into a PID operator along with a hold operating quantity 108b of a hold circuit 108 and an actual taken out quantity 105a obtained by an operator 105, and an operator 109 gives it as an operating quantity of a velocity controller 107 via the hold circuit 108.

摘要： PURPOSE:To prevent surely and beforehand the adverse influences for the equipment, by determining the bulk specific gravity of the raw material tank by detecting the feed rate, cutting-out rate and stock level of the raw material and by detecting the erroneous intake into the tank by means of the difference of this bulk specific density. CONSTITUTION:The raw material is fed to the raw material tank 1 with the feed conveyor 4 for the raw material. The feed rate of raw material at this period is measured with the detector 6 for the feed rate. Bisides, the raw material in the raw material tank 1 is cut out with the cutting-out conveyor 5 and the rate of cutting-out is measured with the detector 7. Further, the stock level of raw material in the raw material tank 1 is detected with the detector 8. By computing the bulk specific density of the raw material which has entered into the raw material tank from these detected values and the volume DELTAV of the raw material in the raw material tank which has changed during a definite period of time and by comparing this bulk specific density with the upper and lower limit values which have been set before hand, the alarm is issued in the abnormal case.

摘要： PURPOSE:To attain high reliability and high flexibility, by controlling each part while estimating the process sensitivity in each region so as to follow interference among processes and demand change and controlling the entire processes through the set of small-sized control logics. CONSTITUTION:A control station 1 operates control devices 11, 12 and 17, a control station 2 operates control devices 13, 14, a control station 3 operates a control device 18, a control station 4 operates a control device 15 and a control station 45 operates a control device 16, and the information of a measuring device existing in an area largely effected with the control of a control device operated by a control station is taken as input information of said control station. That is, each control station collects the measuring information including the information overlapped over plural subprocesses from the subprocess controlled by the control station, and operates the control devices within the area controlled by the station. Thus, even if one control station is failed, the failure does not give any effect on the entire system and the self-control is kept with the remaining normal stations.
