REMOTE SUPERVISORY AND CONTROLLING DEVICE

摘要

PROBLEM TO BE SOLVED: To cause no processing delay although plural slave stations simultaneously collect data and to improve the data collection efficiency by processing the data collected by the slave stations and performing the supervisory control of the objects to be controlled based on those processed data. SOLUTION: A parameter download processing part 14b downloads the data processing parameters of slave stations 11a to 11n which are stored in a data processing parameter storage part 14a. Then the downloaded parameters are sent to the transmission modules 12a to 12n via a transmitting/receiving part 14c and a transmission line 13. The data processing parameter of the corresponding slave station is downloaded again and stored among those parameters received by the modules 12a to 12n. At the same time, the stations 11a to 11n collect the data from their corresponding objects to be controlled and process these data by the parameters stored previously. Then the processed data are outputted to a host computer 16 from a main module 14 via a network 15 and undergo the supervisory control. That is, the data are processed by the modules 12a to 12n and therefore the load on the module 14 is reduced although the data on the objects to be controlled are simultaneously collected by the modules 12a to 12n.
