<p>PROBLEM TO BE SOLVED: To grasp plant information outside the plant site by transmitting the plant information to the outside. SOLUTION: The various kinds of information (such as a process state value) of plant are inputted to a controller 1 and transmitted to a computer 2. When the information of accident occurrence is inputted to the computer 2, an accident occurring signal is transmitted from a radio wave receiver/transmitter 4 to an external radio wave receiver/transmitter 5. A person, who receives the signal of accident occurrence, requests the transmission of required data to the radio wave receiver/transmitter 4 of plant. The radio wave receiver/transmitter 4 of plant transmits data according to the request from the outside. The data to be transmitted are the process state value of computer and the image of ITV or the like. The external radio wave receiver/transmitter 5 repeats this operation and successively acquires data from the plant. In the acquired data, data to be processed are processed by a data processor 6 integrated with the radio wave receiver/transmitter 5.</p> |
