摘要： The invention is characterized in that a remote monitoring center monitors t he combustion vibratory state of the combustor in a turbine installed in a plan t, e.g. a power plant. In order to monitor the combustion vibratory state, combustion vibratory data of the combustor is divided into first data acquir ed in real time and second data comprising representative values, in a specifie d period, determined from the first data. The second data is normally transmitted in a low-speed communication mode and monitored at the monitorin g center. When an abnormal state is predicted as a result of monitoring the second data, the first data is transmitted in a high-speed communication mod e to the monitoring center where the combustion vibratory data is monitored in detail. When a critical state is predicted, switching to a low-load operatio n is commanded to the site as required.

摘要： PROBLEM TO BE SOLVED: To quickly treat a great amount of waste produced in a river without causing traffic jam.
SOLUTION: A drainage pumping station 3 is located in a combined flow area where a branch river 2 joins with a main river 1 connecting to the sea. A port 4 placed facing the main river 1 is further located near to the drainage pumping station 3. Waste collected in the drainage pumping station 3 is stacked on a lighter 6 in the port 4 and transported via the main river 1. The drainage pumping station 3 and a waste incineration site 5 are organically joined via the lighter 6 instead of a truck, thus permitting efficient transportation of waste produced in the branch river and collected in the drainage pumping station 3 and normalizing the function of the drainage pumping station 3.

摘要： PROBLEM TO BE SOLVED: To provide a monitoring picture for facilitating the judgment and operation of an operator. SOLUTION: A plant monitoring and control device (200) for controlling a plant corresponding to the operation of an operator (100) and monitoring the monitoring signal of the plant has a display means for monitoring and a state map display control means (232) for judgement support for displaying the change locus of plural variables and the change of the operating mode of the plant or timing of equipment operation on a map corresponding to the monitoring signal while using the plural variables of the monitoring signal as an axis. The change locus of variables is displayed with plural variables of the plant as an axis and the change of the operating mode of the plant or timing of equipment operation is displayed on this map. Thus, judgement rules are displayed on the same map together with the change of variables, the judgement of the operator to the variable change is facilitated, and the selective judgement of a plurality of operation to plural variable changes can be easily and surely supported.
