PLANT OPERATION SURVEILLANCE SYSTEM

PURPOSE:To enable early detection of abnormality indicant and improve safety by providing a sensor means to detect sound and image of components constituting a plant and indicating the operation status of the plant with the sound and a simulating image. CONSTITUTION:A means to detect images of a TV camera 5 and an infrared ray camera 6 and a means to detect sound from a microphone 7 etc. are constituted so that the operation status of a plant is indicated with the sound and a simulating image. For example, the temperature information from the infrared ray camera 6 is indicated in the screen such as CRT 20 and the like with different colors for each temperature of components, or the sound of operating components which is detected with the microphone 7 is plaied in the central control room. Thus, the operation status of the plant is expressed with presence. Then the operators can catch the operation status more precisely than before and so early finding of abnormality indicant and the like can improve safety.
