Abstract

PURPOSE:To cause the condition grasp of a process control system to more accurate and to increase the stability of a process control by providing a photographing device having transmitting and receiving functions, providing a transmitter-receiver to execute a communication with the photographing device to the control device of a process supervisory system, and executing the communication. CONSTITUTION:At the time of photographing a part 8 to be photographed, a photographing person 5 to mount a photographing device 6 at a head part observes the part 8 to be photographed. Consequently, the sight line of the photographing person 5 and the direction of the photographing device coincide, and a range seen by the photographing person, namely, the part 8 to be photographed is displayed through the photographing device 6, a signal cable 62, a transmitter-receiver 64, an antenna 63, a wave 9, a transmitter-receiver 4, and a control device 2 on a display 1. Thus, the photography information of the control device 2 can be displayed, the condition grasp of the control device 2 can be made more accurate, and thereby, the control device 2 can be stably operated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a monitoring system for a process control device, and particularly to a process monitoring system suitable for displaying process photographic information.

[Conventional technology]

Conventional devices were configured to input plant process values and display them on a display device, as described in Japanese Patent Publication No. 62-26469. This is the general form of a process monitoring system. A simplified diagram of this is shown in FIG. 2, which shows a conventional example. That is, input signals received from sensors 3 provided in the process are processed by the control device 2 and displayed on the display device 1 to monitor the process.

[Problem to be solved by the invention]

The process monitoring system according to the above-mentioned conventional technology mainly processes input signals received from sensors attached to the controlled object and displays them on a display device, and images the operating state of the controlled object itself and displays it on the display device. No consideration was given to this.

For this reason, there are limits to accurate understanding of on-site conditions.

In particular, there was a problem in that it was difficult to obtain the necessary information when there was a large change in the control status or a malfunction occurred.

The purpose of the present invention is to make it possible to simultaneously display photographed information from the field in addition to the display contents according to input signals received from conventional sensors, to more precisely grasp the status of the process control system, and to increase the stability of process control. It's about trying to make it happen.

[Means to solve the problem]

The above object is achieved by providing a photographing device with a transmitting/receiving function, and further providing a transmitting/receiving device for communicating with the photographing device in a control device of a process monitoring system.

[Operation] When connecting the imaging device and the control device wirelessly, there is a risk that radio waves may leak to the outside of the system and cause adverse effects.
This weakens the radio waves and allows the transmitter/receiver on the control device side to be used by the process monitoring system.

〔Example〕

Embodiments of the present invention will be described below with reference to FIG.

1 is a display device, and currently CRTs are often used.

Reference numeral 2 denotes a control device that processes human power signals from sensors 3 and the like and displays them on the display device 1.

4 is a device that communicates with the photographing device 6. 5 is the photographer, 7 is the object to be photographed, 8 is the area to be photographed by the photographing device 6, and 9 is transmitting and receiving with the photographing device 6 (a device communicates with the photographing device 6. shows.

Further, 61 is a human head-mounted helmet to which the photographing device 6 is attached, 64 is a transmitting/receiving device, 62 is a signal cable connecting the photographing device 6 and the transmitting/receiving device 64, and 63 is an antenna.

We will consider how to obtain photographic information about a certain part of the controlled object. There is an option to fix and install the photographing device at a key point, but there is a limit to the number of devices that can be installed and there are restrictions on the area to be photographed, so human photography is essential.

According to the present invention, when photographing the part 8 to be photographed, the photographer 5 wearing the photographing device 6 on the head looks at the part 8 to be photographed, thereby changing the line of sight of the photographer 5 and the direction of the photographing device. match, the range that the photographer is looking at, that is, the area to be photographed 8 includes the photographing device 6, the signal cable 62, the transmitting/receiving device 64, and the antenna 63.
, the radio wave 9, the transmitting/receiving device 4, and the display device i via the control device @2.
i1.

A feature of this process monitoring system is that it can display photographic information of the controlled object on a display device. Furthermore, the photographer can photograph any part of the controlled object.

Since the photographing device is attached to the head of the photographer, both hands of the photographer are free, and it is possible to perform photographing work and maintenance work at the same time. Further, the photographing information on the display device @1 can be monitored by a plurality of monitors, and more appropriate instructions can be given to the photographer 5.

〔Effect of the invention〕

According to the present invention, it is possible to display the photographic information of the control device, and the state of the control device can be grasped more precisely, so that the control device can be operated stably.
