摘要： PURPOSE:To keep the pressure of a terminal having no sensor within a predetermined pressure deviation by estimating each demand quantity of the demand terminals on the basis of the detected flux and pressure so as to control fluid transport in a pipeline network. CONSTITUTION:Observation data zt on flux and pressure measured at a time by a sensor 11 is input to a demand quantity estimating apparatus 2. The demand quantity estimating apparatus 2 is adapted to estimate the quantity of demand at the time (t) on the basis of the observation data zt, operation quantity deviation DELTAut, a demand estimated value yr and a target value zr and select from a table a base pattern of each demand terminal input from the outside to be output. According to the output base pattern Br and a current pattern Cr, a demand forecast apparatus 5 is adapted to make a forecast of demand of the day so as to control fluid transport in a pipeline network. Therefore, even the pressure of a demand terminal having no sensor can be kept within a predetermined pressure devication.

摘要： PURPOSE:To receive plural screen images at a time by inserting a screen recognition code EN into an unused part of the internal CAPTAIN(Character and Pattern Telephone Access Information Network system) standard protocol in a sent screen image on a center side at the time of screen information transmission. CONSTITUTION:A free line of a communication network is accessed by operating a keyboard 54. Then a user inputs a 9-digit screen image request code by operating keys 54 for a request for one kind of image. The request code signal is converted by a CAPTAIN terminal controller 52 into data format regarding CAPTAIN PLPS and sent out to the communication network 30. The information center 10 sends it to a screen editing processor 12 through a switch 20 and a computer retrieves a data base to select requested image information. The selected information with the EN code is inputted to the RAM in a terminal controller 52 through the network 30 and displayed on a display device 56 through an image conversion interface. The line is turned off after the information is stored in the RAM, and the user obtains a hard copy on a device 58 or stores the information on a floppy disk 60. This constitution enables the batch reception of only screen image information specified by the reception side.

摘要： PURPOSE:To enable the users except the program specialists to operate an information conversion system by describing the conversion drawing methods of the information and the external information source information as the knowledge. CONSTITUTION:A knowledge store part 11 stores a rule group describing the conversion method between the graphic variable information and the external information source postulate/result information and a rule group describing the conversion method between the graphic variable information. Therefore the conversion methods of the chart information and the external information source information can be freely described at the part 11 as the knowledges with no use of a program. Based on these knowledges, an information conversion part 7 serving as an inference mechanism performs the conversion of information with no malfunction. As a result, the users even if not program specialists can operate an information conversion system and also can easily and immediately produce the conversion method between the optional external information sources and the charts produced as necessary. Then the working efficiency is improved.

摘要： PURPOSE:To attain more accurate information service by using a missing data monitor means to find out the missing data if there is any missing data in the sent observed information and using a missing data interpolation input means so as to interpolate the missing information. CONSTITUTION:The observed information is subjected to reception processing at a reception processing section 18 in an information center 12 and the presence of a fault of a reception data is detected by a data detection section 20. When the data detection section 20 detects the presence of a fault in the data, the missing data monitor section 28 monitors the presence of the missing data and when the missing data is detected, the missing data is subjected to interpolation processing by a missing data interpolation processing section 30. Then a data pattern edit processing section 22 processes the observed information sent from an observing device 10 in on-line or off-line and stored in a data file 24 and required pattern information offered to a subscriber is edited from the observed information in the data file 24 and stored in the pattern file 26. Thus, the required pattern information is generated efficiently.

摘要： PURPOSE: To reduce the reproducing time of image data by successively overlapping the images related to varying plural data on the image related to beforehand received nonvarying image data and displaying them on the display of a CAPTAIN terminal. CONSTITUTION: Through a history key input on a keyboard 64 of a CAPTAIN terminal 50, a CPU 56 retrieves a RAM 60, obtains beforehand stored history screen request data and obtains the map information, which becomes a background picture, from a floppy disk 70. Then, the CPU 56 decodes a next picture request number and transmits the data related to the request number through a communication/line control interface 52. A CAPTAIN image editing and processing device 12 of an information center 10 transmits the requested picture, files the image in the disk 70, the background image is first displayed on a display 66 and then, the image related to varying plural data such as area precipitation data are successively overlapped and displayed.

摘要： PURPOSE:To reduce a danger for overflow sewage out of a waterway at the upstream side, by providing a detecting means for water levels of both upstream and downstream sides of a gate set to the waterway, a means which decides the opening/closing direction of the gate, etc. CONSTITUTION:A detecting means detects the water levels at the upstream and downstream sides of a gate set to a waterway. In addition to this detecting means, a means which detects the opening/closing directions of the gate, etc. are provided. For instance, a water level detector 201 detects the level h1 at the upstream side of a gate 203 set to a waterway 1. While, a water level detector 204 detects the level h2 at the downstream side of the waterway 1. Then a gate opening/closing direction deciding circuit 214 compares the level h2 with reference water levels H3 and H4 which should be kept under control of the gate 203 and then delivers a command signal to a gate opening/closing device 202 to control the opening/closing of the gate. A difference arithmetic circuit 212 calculates the difference between levels h1 and h2. This difference value is supplied to a gate opening/closing speed deciding circuit 211 to decide the opening/closing speeds of the gate 203. This decided speed is delivered to the device 202.
