摘要： PROBLEM TO BE SOLVED: To allow plural servers related with fault generated in one server to simultaneously execute the preserving operation of fault analysis information. SOLUTION: In a computer network constituted of a monitor terminal equipment 11 and plural servers 12A-12D, each server 12A-12D is provided with a data file 55 for storing fault analysis information for each software in a data processing process and a function for transmitting a fault communication message including the identifier of the software which is being executed to the monitoring terminal equipment 11. Moreover, the monitoring terminal equipment 11 is provided with a function for commanding the preservation of fault analysis information to one or more servers specified by the software identifier included in the fault communication message in response to one fault communication message received from any server. Thus, any artificial operation can be unnecessitated, and any information loss due to the delay of the preserving operation can be prevented.

摘要： PURPOSE:To detect the runaway of an individual program without disturbing the functions of both general and individual controls, by providing a setting part, a resetting part and a deciding part for flag bits. CONSTITUTION:A flag bit setting part 6 has a flag bit corresponding in 1:1 to each C mode individual program and sets '1' to all flag bits via a processor 2 every time an S mode general program is started. A flag bit resetting part 7 has a flag bit corresponding in 1:1 to each C mode program and produces a resetting signal when the execution is through. A flag bit deciding part 8 decides whether a flag remains or not at the part 6. If the presence of the remaining flag '1' is confirmed, the part 8 produces an alarm signal and displays a specific one of C mode programs C1-C10 that has runaway at a display part 10 including a lamp 11 and a CRT 12.

摘要： PURPOSE:To collect data effectively for a desired slave station device by selecting the data collecting cycle which is started by a telemeter device as well as the slave station device based on the part achievements. CONSTITUTION:A data processor 3 calculates the changing factor between a reception data input signal A supplied from a telemeter device 2 and the data collected and recorded in a preceding cycle and compares this changing factor with that set previously. When the changing factor calculated by the processor 3 exceeds a prescribed level, a call cycle switching signal B which changes the data collection cycle according to said changing factor is outputted to the device 2 from the processor 3 together with a slave station designating call signal C which starts a specific slave station device 1. Then the device 1 is started based on the data collection cycle of a slave station call control part 10 of the device 2 and the number of the device 1. The device 1 sends the measured 4 data to the device 2 if its own station is started.

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： PROBLEM TO BE SOLVED: To make always obtainable a water-level measured value of high reliability even when the field of view of a TV camera is blocked temporarily due to a change in weather conditions or even when the operation of a contact- type water leval gage (e.g. a float-type water level gage) is disturbed due to a foreign matter in the water of a river. SOLUTION: An image-processed water leval signal (a) which is obtained in such a way that the image output of a TV camera 4 used to image respective indicating members 5, 6, for water-level measurement, installed near the surface of the water and a water level signal (b) which is obtained in such a way that radio waves transmitted from a float-type water level gage 9 are processed by a receiver 10 and a coder 11 are input to a data processor 8. Both water level signals are compared and computed by the data processor 8 according to a program which is given in advance. Thereby, a water-level measured value of high reliability is calculated.

摘要： PROBLEM TO BE SOLVED: To obtain a liquid level by photographing a vertical staff-gage by a camera and processing an image. SOLUTION: A vertical staff-gage installed at a liquid level measuring place is photographed by a camera from a place apart from the staff-gage, and an image photographed is processed so as to obtain a liquid level position. In this case, the image of a vertical staff-gage 6 reflected from the liquid surface is cut by a filter 4 before the staff-gage 6 is photographed by the camera 2 so as to identify an actual image and a reflected image of the vertical staff-gage in the photographed image in order to obtain a liquid level position. Because the reflected image obstructing the measurement of liquid level is cut off, the actual image and reflected image of the vertical staff-gage can be identified easily from each other so as to obtain the liquid level.

摘要： PROBLEM TO BE SOLVED: To improve the safety of gate control by providing an automatic control operation time limit timer and stopping control when the entire operation time exceeds an automatic control operation limit time. SOLUTION: A gate operation amount limit timer 104 inputs the open signals of a gate control part 103 and monitors the continuous operation time of the opening operation of a gate 105. When the continuous operation time exceeds an operation amount limit time, gate stopping signals are outputted to the gate control part 103 and an alarm is simultaneously outputted. The automatic control operation time limit timer 108 inputs control state monitoring signals from a controlled variable computing part 101 and an open degree control part 102, inputs the open signals from the gate control part 103, recognizes the state of automatic control by the signals and measures the entire operation time of the automatic control. Then, when the entire operation time reaches the automatic control excessive operation limit time, stopping signals are outputted to the gate control part 103 and the gate is stopped.

摘要： PURPOSE:To easily decide the part of the equipment where the maintenance is required for an outworn pipeline, etc., by displaying the equipment diagnostic information on the pipelines, etc., shown on an equipment drawing in different patterns like the line types, the line widths, the colors, etc. CONSTITUTION:A cursor CU which moves in 1:1 with the operation of a mouse 207 is shifted to an icon area 102 of a display screen 101. Then an icon of 'drawing retrieval' is selected. The drawing retrieving jobs include the drawing No retrieval which designates directly the desired drawing No, the index retrieval which retrieves the desired drawing out of an index diagram showing the overall drawing position relation, the target retrieval which designates a target, the town name retrieval which designates a town name, etc. These different types of retrieval are properly used in accordance with each use. When this selection command is inputted to an operation input part 104 of a CPU 201, a graphic editing part 109 and a display editing part 111 edits the relevant drawing data in accordance with a drawing display area 103 and displayed on this area 103. Thus it is possible to easily select the equipments like the pipelines, etc., requiring the maintenance.
