摘要： PURPOSE:To execute an operation by a few operation switches against many operations and also by the same sense as that in using a conventional separate operation switch, by displaying a name of a final control element to be operated and an operation display on the operation switch, or on its vicinity. CONSTITUTION:An operation switch itself containing a name plate, too is pro vided with a display function, and a display of a name of a final control element to be operated and its operation is executed automatically, and an operation switch provided with an indicator can be realized by using, for instance, a liquid crystal indicator and combining an illumination type push-button switch to a base. When an A-BP pre-condition 36 has been formed, a break point name is displayed on a display part of an operating device 42, and when an operator confirms it and operates the switch of the operating device, an advance permitting command 35 is outputted, and after AND to the pre-condition 35 in a computer, an A-BP on-signal 37 is outputted. When a B-BP pre-condition 46 has been formed, a name of a break point B is displayed on the display part of the operating device 42, and the previous break point display is turned off.

摘要： PURPOSE:To permit a little backup controllers to cope instantaneously with a case where a normal controller is troubled by loading control mechanism programs of M-units of controllers with priority among N-units of normal ocntrollers on a backup controller. CONSTITUTION:The control system of a power plant is provided with N-units of normal controllers 19, M-units of backup controllers 26 and a program loading device 16 provided with a function loading a function program to each controller 19. The priority order of each normal controller 19 is decided in accordance with the hourly sections of operating stages from the activation, operation and stop of the power plant on the basis of the states of the plant and controller at each stage. According to the priority order, the function program of the normal controller 19 is previously loaded on the backup controller 16. Thus the backup controllers less than the normal controllers cope instantaneously with the case where the normal controller 19 is troubled, thereby executing the backup of the control function of the troubled controller.

摘要： PURPOSE: To keep a constant O
2 /coal ratio and the max. cold gas efficiency and to economically gasify coal, by controlling the amt. of O
2 necessary to gasify the coal and precedently the amt. of air serving as the raw material for the O
2 in response with varaition of a demand from gas users.
CONSTITUTION: The amt. 19A of O
2 in response with the amt. of coal is determined bymultiplying a fuel gas demand signal (coal requirement signal) 1 from gas users by an O
d /coal ratio set value with 9 multiplier 19, and then calculated in terms of the amt. of air with a function generator 20 and further calculated in terms of equivalent degree of opening of an air flow control valve 4 to form a precedent control signal 20A, which is added to an opening degree signal 15A due to oxygen perssure control in the succeeding stream of an O
2 generator 13 usign an adder 21, to precedently control an air flow rate with an air flow control valve 14. On the other hand, the flow rate of the coal is controlled with a control valve 4 and deviation between an O
2 /coal ratio set value 8 and an actual O
2 /coal ratio determined by dividing an actual amt. 12 of O
2 of an actual amt. 5 of coal by a divider 6, is operated with a subtractor 7 to control the O
2 flow rate through a PI calculator 9 with a control valve 11. The controlled amt. of O
2 is supplied to a gasifier 10 to gasify a required amt. of coal.

摘要： PURPOSE:To cope with influence on abnormality detection by a natural phenomenon and to surely detect the abnormality of equipment by setting an area for detecting the natural phenomenon for pictures grasping the state of the equipment. CONSTITUTION:In pipings 7-9, the states where abnormalities 13-15 are generated are respectively image-picked up by ITV cameras 16 and 16' and the pictures are inputted through an ITV camera controller 17 to a picture processor 18 and are displayed at a display device 21 at the same time. Then, a normality lamp 24 is lighted when a result obtained by picture processing is 'normal' and when it is 'caution', a caution lamp 25 is lighted, the condition is displayed at the display device 22 at the same time and a monitoring person is urged to confirm a screen. Also, in the case when the result is 'abnormal', an abnormality lamp 26 is lighted and at the same time, an alarm 23 is issued and displayed at the display device. In this case, differential pictures of time fluctuation are found from the picture processing of the entire area and the picture processing of the area for detecting the natural phenomenon, both pictures are combined and the abnormality is detected.

摘要： PURPOSE:To reduce a memory for storing a reference image to be a reference, and to accurately detect abnormality. CONSTITUTION:An image inputted in the case of starting sampling is defined as the reference image, and difference from current images inputted later at fixed intervals are accumulated for prescribed time. Then, the normal image of the same object is selected by a camera control part 2, transformed to an (x) projection distribution pattern and stored in a normal pattern memory 4. After the density is corrected at an illuminance correction part 5, the inputted current image is compared with a normal pattern after being transformed to the (x) projection distribution pattern, and the abnormality is judged. Thus, the memory for storing the reference image to be the reference can be reduced. Further, even when the background is complicated and the accuracy is considerably changed, the abnormality can accurately be detected.

摘要： PURPOSE:To automatically confirm the operating state of a plant by selecting a corresponding monitoring process item when abnormality or the change of an operating state is generated in an objective plant, collecting process values and automatically displaying the collected data on a trend graph. CONSTITUTION:A signal S3 indicating the operating state of each part of the plant is successively fetched into a selection means 2. Knowledge for deciding the operating state of the plant 1 based upon the signal S3 is stored in a knowledge base 3. The means 2 checks the operating state of the plant 1 based upon the signal S3 and the knowledge stored in the base 3. When any one of the parts of the plant 1 generates abnormality or the change of the operating state and necessity for monitoring the operation state of the process item is judged, the process item is selected. A signal S4 for defining the process item is outputted to a data collecting/storing means 4. The means 4 extracts a signal S5 indicating the operating state of the process item defined by the signal S4 from the plant 1, stores the signal and then displays the stored contents on a display means 5 as a trend graph.

摘要： PURPOSE:To quickly cope with the sequence delay by selecting automatically a suspected area for the factor of the delay and selecting the optimum one of plural monitor cameras and heating microphones respectively set at each place of a plant to transmit the outputs of these selected camera and microphone to a remote display device. CONSTITUTION:A camera control part 2 of a site monitor device 1 is actuated by a sequence delay information signal 10 received from a sequence master 6. Then an optimum site monitor camera 4 is selected to pick up a delay factor area and then actuated by a camera switching part 3. Then, the information on the delay area obtained by the camera 4 is projected on a remote display device 5 via a control part 2. An operating terminal 7 of the master 6 is operat ed by an operating signal 11 given from the master 6 and an operating signal 12 received from an individual operating switch 8. In other words, the visual monitor of a camera and the acoustic monitor of a microphone are secured at the important areas including the terminal 7, etc. Thus, the relevant informa tion is informed to an operator when a sequence delay occurs.
