Abstract

PURPOSE:To increase the monitoring efficient and to execute the suitable condition judgement when the accident occurs by selecting the prescribed place of the schematic flow diagram as a key when the screen suitable to the operation condition is selected from many screens. CONSTITUTION:The device is provided with a process 1, an industrial computer 2, a CRT displaying device 3, a screen selecting input device 4 and a touch sensor 5. The condition of the process 1 is detected by various sensors and fetched into the computer 2. Next, the necessary data are edited from a process variable to a displaying screen and the whole schematic flow diagram is displayed onto the device 3. An operator, while he watches the screen of the schematic flow diagram, touches, the place for while he wants to know the process condition in detail, in the screen, and then, the sensor 5 communicates the position to the computer 2. The computer 2 calculates the necessary data to display the equivalent place from the position information inputted by the sensor 5, and displays the detailed schematic flow diagram, etc. In such a way from the whole schematic flow diagram, the operator can retrieve the screen as a series of the flow.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a process monitoring device having a man-machine interface for monitoring and controlling plant systems.

[Conventional technology]

Conventionally, there was a device of this type as shown in Figure 3.
In the figure, (1) is the process to be monitored, (2) is the industrial computer that creates the screen to be monitored, (3) is the CRT display device that displays the screen, and (4) is the screen for selecting the screen to be monitored. This is a selection input device. CRT display device (
3) A screen like the one shown in FIG. 4, which is generated by the program of the industrial computer (2), is displayed at , h.

Next, the operation will be explained based on the above configuration.

The status of the process (1) is detected by various sensors, is imported into the industrial computer (2), and the necessary data is edited and processed on the display screen based on the process variables, and the data is displayed on the CRT in the form of numerical display, graph display, graphic display, etc. Displayed on the display device (3). The screens displayed on the CRT display device (3) are stored in the industrial computer (2), and the operator selects and displays the corresponding screen via the screen selection input device (4).

[Problem that the invention seeks to solve]

Conventional process monitoring equipment is configured as described above, so when monitoring the movement of a plant that is in a certain operating state, the operator can determine which screen displays the relevant plant movement in the current plant state. Therefore, the monitoring efficiency varies depending on the monitoring ability of the operator. Another drawback is that when it is necessary to urgently grasp the status of a predetermined plant due to the occurrence of an accident, the target screen cannot be displayed immediately.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology. The purpose is to provide a process monitoring device that allows you to select screens.

[Means for Solving the Problems] The process monitoring device according to the present invention displays the states detected by the monitoring device in a system diagram, and uses this as a search base.
Then, when the operator specifies the part of the screen that is to be monitored, the monitoring device displays a screen displaying related screens such as an enlarged view of the specific process system and diagrams and tables containing plant variables related to the process system. It is equipped with a search function for selection.

[Effect]

The search function of this invention allows an operator to select a screen from a system diagram by selecting a predetermined location on the system diagram as a key when selecting a screen suitable for the operating condition from among a large number of screens. Reduce load and prevent mistakes in accessing necessary information.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, (1) is a process, (2) is an industrial computer, (3) is a CRT display device, (4) is a screen selection input device, and (5) is a touch sensor serving as screen designation means. An industrial calculator (2) is mounted on the CRT display (3).
) A screen like the one shown in FIG. 4, which was generated by the program, is displayed.

Next, FIG. 2 shows an enlarged screen of the location indicated by the touch sensor (5).

Next, the operation will be explained. The state of the process (1) is detected by various sensors and is input into the industrial computer (2). Then, data necessary for the display screen is edited from the process variables, and the entire system diagram as shown in FIG. 4 is displayed on the CRT display device (3). While looking at the system diagram screen, the operator touches a point on the screen where he wants to know the process status in detail, and the touch sensor (5) transmits the touched position to the industrial computer (2). The industrial computer (2) calculates the data necessary to display the relevant location from the position information input by the touch sensor (5), and displays a detailed system diagram or a screen containing plant variables related to that location as shown in Figure 2. Display as shown. The operator can search the screen as a series of flows from the overall system diagram as described above. Further, in the case of a diagram or a table containing plant variables, the display is enlarged to one screen by input from the touch sensor (5) as described above.

In the above embodiment, the screen selection is performed using a touch sensor, but the screen selection may be performed using a trackball or Yauss.

Further, in the above embodiments, a CRT display device was described, but an LED display or a liquid crystal display may also be used, and the same effects as in the above embodiments can be obtained.

〔Effect of the invention〕

As described above, according to the present invention, since the screen that displays the status of the location that the operator wants to know from the overall system diagram is made removable, the 1M transferee is required to memorize the monitoring screen related to each location. It also prevents switching to unnecessary screens or overlooking necessary screens when searching, increasing monitoring efficiency and making it possible to make appropriate situational judgments in the event of an accident. There is.
