Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation diagnosis system for diagnosing an operation state of a plant control system.

[0002]

2. Description of the Related Art In recent years, in the field of process control, so-called supply chain management (hereinafter referred to as SCM).
The concept called ") is drawing attention.

FIG. 2 shows an SCM in the field of process control.
It is a figure explaining the concept of. In FIG. 2, a manufacturing process A1, A2, A3, A4 of a product A and a manufacturing process B of a product B
1, B2, B3, B4, production process C1, C2 of product C
C3 and C4 are respectively geographically separated,
Operation control and operation data indicating operation conditions are collected by an independent process control system. Based on the operation data, each process control system is operated by a skilled operator.

[0004] Then, the SCM sequentially orders the products in each process, for example, in FIG.
In the case of distribution to the next process such as A3 → A4, information is shared among the horizontal production processes A1, A2, A3, and A4 to optimize production speed, production volume, delivery date, cost, etc. It is to try to make it.

[0005]

However, for example, when the process control systems for controlling the manufacturing processes A4, B4 and C4 of different products require common operation control knowledge, a skilled operator having the same knowledge is required. However, there is a problem that a plurality of processes are required for each manufacturing process (for each location of the manufacturing process) and it is difficult to secure human resources.

Further, the knowledge of one skilled operator is geographically restricted and cannot be effectively used globally. That is, information in the vertical direction is shared with the conventional concept of the horizontal SCM. There was a problem that there is no.

[0012]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of one embodiment of the present invention. In FIG. 1, the driving diagnosis system includes a plurality of process control systems 1, a data transmission device 2, a driving diagnosis terminal 3, and a data server 4.

The process control system 1 includes a control station 5 and an operation monitoring station 6, and the control station 5 is connected to a dedicated network 7,
The operation data indicating the operation state of the instrumentation device (not shown) is collected, and the instrumentation device is controlled (PID control and sequence control) according to a predetermined control program. still,
The instrumentation device is, for example, an industrial instrument, a control valve, or the like as a detecting end for measuring an industrial quantity of the plant such as a temperature, a pressure, and a flow rate.

The operation monitoring station 6 is connected to a dedicated network 7, and a field operator operates an instrumentation device from the operation monitoring screen of the operation monitoring station 6 (outputs an operation command signal of the instrumentation device to the control station 5). Also, operation data indicating the operation state of the instrumentation device is fetched from the control station 5 and displayed on the operation monitoring screen to monitor the operation data.

The operation monitoring station 6 is connected to a general-purpose communication network 8 corresponding to a communication protocol used for general communication.
