摘要： In an automatic control system, controls receive an input indicative of a deviation between feedback and demand signals and produce an output which in turn is applied to a plant to control it. A diagnostic device includes a model having an equivalent characteristic to the controls and receives the deviation signal. When a noise coming into the automatic control system is detected or when a deviation between the outputs of the model and controls is sufficiently small, no model operation is performed, and the output of the controls is determined as that of the model. However, when the deviation between the outputs of the model and the controls is large, the model is supplied with an input thereby performing a model operation. A resultant output of the model is then compared with the output of the controls to produce an alarm indicative of an abnormal state of the controls in accordance with a deviation between these outputs.

摘要： A boiler/turbine plant controlling apparatus comprises a circuit for driving a turbine inlet steam flow regulator valve on the basis of a difference between a load command signal adjusted by a thermal stress value of a turbine and an actually measured output signal of a plant; a circuit for driving a boiler feed water flow regulator valve on the basis of a difference between a value which is obtained by adding a boiler feed water amount with a super heater feed water amount and a value represented by a boiler input command signal; a circuit for driving a fuel flow regulator valve in accordance with an actually measured fuel amount and a fuel command signal corrected by a difference signal between a primary steam temperature setting signal and a steam temperature signal representative of a primary steam temperature measured value; a circuit for driving a super heater water feed valve on the basis of a difference value between the primary steam temperature setting signal and the steam temperature signal; a circuit for calculating a steam temperature drop through the steam flow regulator valve on the basis of an opening degree of the steam flow regulator valve disposed at an inlet of the turbine and a temperature and pressure of steam at the inlet of said steam flow regulator valve; and a circuit for correcting the steam temperature setting signal on the basis of the calculated value of the calculating means.

摘要： The present invention relates to a method of controlling the operation of large rotary machines such as steam turbines and generators in a thermal power plant or nuclear power plant. More specifically, the invention relates to a method of controlling such operation as increasing or decreasing the speed of the rotary machines or stopping the operation of the rotary machines, by detecting vibration at the time of starting the operation or during the steady-speed operation, by analyzing the detected vibration signals to determine whether the operation is in normal condition or abnormal condition, and by detecting or forecasting the cause in case the operation is in abnormal condition.

摘要： An electromagnetic guidance system used, for example, for guiding a driverless mobile vehicle. For example, a two-core wire or cable is in the surface of a travelling course. The core conductors of the two-core wire are connected at its end so that current may circulates through the conductor. By detecting the magnetic flux induced by the circulating current by means of detecting coils mounted on the driverless mobile vehicle, the vehicle can be automatically run along the two-core wire without any change-over operation.

摘要： In a system for optically detecting with a plurality of light detecting elements a reflecting object in the form of long stripe disposed on the surface of a traveling path, the average value of the respective electric quantities derived from the light detecting elements is obtained through arithmetic operation and the reference value is automatically changed according to the degree of the surface being soiled, by multiplying the average value by a certain safety factor, so that accurate detection can be performed independent of the degree of the soil on the traveling path surface.
