2. Description of the Related Art A large-scale plant system such as a nuclear power plant is composed of a large number of equipments, instrumentation and systems that make up the plant. The operation is performed according to a command based on the judgment of the host system and the operator.

However, conventionally, judgment and processing functions relating to the operation of all plants are concentrated in the above-mentioned integrated system. Since the control system of this plant becomes very large-scale, and the reliability of this control system greatly affects the reliability of the entire plant, redundant measures such as duplication are usually taken. This centralized system became extremely large, and in order to avoid this as much as possible, measures were taken to siphon plant data and simplify these judgment and processing functions. Among the individual equipment, instrumentation, and system information, there are some that can monitor the processing results of the integrated monitoring system in the central control room or the like, but there are many that are dispersed in the plant. In particular, local equipment installed in a special atmosphere, monitoring of instruments, operation, preparation in advance,
Procedures were required, and a great deal of effort had to be spent on monitoring operating conditions and addressing methods and actions for signs of abnormalities or current conditions of abnormalities. Furthermore, it was not possible to manage the situation of work on the spot in detail, and it was insufficient to grasp the achievement level of the work on the spot.

Furthermore, even when the plant condition changes suddenly,
Conventionally, in order to grasp detailed information about equipment and instrumentation distributed in the plant, and to take appropriate measures and restoration operations, advance preparations and procedures are required each time in a special atmosphere.

Also, regarding the selection of instruments, devices and systems to be treated, a method of manually isolating a part of the system is carried out in order to eliminate defective parts by looking at the plant state, and a human being directly on site. There is a problem that it is difficult to take prompt measures in an environment where work cannot be performed.

The present invention has been made in view of the above circumstances, and its purpose is to provide instrumentation and equipment for constructing a plant for operation and management of the entire plant including on-site work in a large-scale system such as a nuclear power plant. In addition, by making the system highly autonomous and enabling it to be performed with a sense of realism, complex on-site work in a poor environment environment and maintenance and operation of the plant without human intervention can be performed autonomously and transparently. By providing the plant control device, the safety and reliability of the plant can be improved.
