Operators must watch a plant not to fall into abnormal state and operators are required to judge quickly and properly for appropriate actions in case of an abnormal state. In this paper, a new display method of state variables using Tree Patterns is proposed as a condition monitoring tool to overcome the above difficulty, and its characteristics and experimental examples are described. As an example, applying this method to the monitoring of spatial temperature distribution of once-through steam generator, the following main results are got; (1) Tree Patterns are easy to draw and are easily programmable by a mini-computer. (2) Tree Pattern can change its form widely by six parameters, especially by an angle of branching and the characteristics can be used as a new method of condition monitoring by corresponding state variables to these parameters. (3) A wood pattern made from plural tree patterns is adequate to display the state variable distribution of a distributed parameter system. (4) Manual control tests by monitoring Tree Patterns display are assured as well as those by conventional analog indicators.
