Title: Remote observation system having transmission line for isolating local area network at data gathering site from remote monitoring site, and having provision for data request from remote monitoring site via the transmission line

Abstract: An remote observation system including a hypertext data transmitter for transmitting hypertext data from an observation object side to an office side through a data transmission line connecting therebetween, and a hypertext display unit for displaying at the office side the hypertext data sent from the observation object side. The hypertext data consist of a combination of fixed image data representing a plant in its entirety and status data of various portions of the plant, which are collected by a data collection device. This makes it possible to solve a problem of a conventional remote observation system in that only insufficient information is acquired at the office side because the office side is not directly connected with the observation object side, and hence the office side can acquire the information on the states of the observation object side only when the observation object side sends reports to the office side.
