Abstract

PURPOSE:To attain a pleasant operation of a monitor control system by providing an operator file, an operator identifying means, and an environmental parameter accumulating means and using these means selectively to attain an operating environment. CONSTITUTION:An operator inputs the prescribed key data or ID number data, the fingerprint data, etc., through a data input means 1. These data are received by an operator identifying means 2 and this means 2 identifies a specific operator. An environmental parameter accumulating means 4 selects a proper guidance message group out of a data file area 3a based on the data on the level, the expertness, the operating history, etc. A monitor control part 5 reads a proper parameter out of a group of parameters of the means 4 and then reads out a necessary guidance message while deciding sequentially the conditions. Then the part 5 displays the guidance message on a display device 6 and produces an operating environment.

Description

[Detailed Description of the Invention] [Object of the Invention (Industrial Application Field) The present invention provides a security system for plants and buildings,
The present invention relates to a supervisory control system used in FA (factory automation), etc., and particularly to a supervisory control system that improves operability for operators.

(Prior Art) In this type of supervisory control system, a supervisory console equipped with a CRT display is installed in a supervisory room, and an operator can monitor various operating states of the plant, guidance messages, etc. displayed on the CRT display of the supervisory console. By sequentially operating the keyboard and switches based on the information, settings values necessary for controlling the operation of terminal devices and processes are changed.

At this time, guidance messages are provided to the operator from the system itself to alert the operator to avoid erroneous operations and settings, and to ensure smooth operation. Various operating states, guidance messages, etc. are always fixed.

(Problems to be Solved by the Invention) Therefore, in the above-described supervisory control system, operators perform operations based on guidance messages on a CRT display, but each operator has a different optimal operating environment.

For example, if the operator's level or proficiency with the system is low, it is desirable to provide detailed and kind guidance messages, but on the other hand, if the operator is sufficiently skilled, excessive guidance messages may be rather annoying. This is often disadvantageous in terms of operational speed and efficiency.

The present invention has been made in view of the above-mentioned circumstances, and aims to provide a monitoring and control system that provides a variable operating environment for each operator or according to the operator's proficiency level, and allows comfortable operation for each operator. purpose.

[Configuration of the Invention (Means for Solving the Problems) In order to solve the above problems, the present invention provides an operator file in which operator guidance ψ message groups and parameter groups are stored, and input operator identification data. operator identification means for identifying an operator from the operator; and operator response based on the operator identification signal identified by the operator identification means, or guidance message group from the operator file and the an environmental parameter accumulating means for reading a group of parameters and defining and accumulating the contents of an operating environment suitable for the operator; This configuration realizes an operating environment by selectively using a guidance message group and the parameter group.

(Function) Therefore, the present invention takes the above measures, so that when operator identification data related to key operations, ID cards, fingerprints, etc. is input, the operator identification means identifies the operator based on the operator identification data. identify Here, the environmental parameter storage means reads the guidance message group and the parameter group from the operator file for each operator based on the operator identification signal obtained by the operator identification means or based on the level, proficiency, etc. of the operator. Define and store the contents of the operating environment suitable for the operator. after that,
When this operator operates, it receives the operation data, judges various conditions from the parameter group, extracts and displays appropriate guidance messages from the accumulated contents, and displays messages that match each operator or the level of the operator. It allows for comfortable operation.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram of the system of the present invention.

In the figure, 1 is a data input means such as a keyboard, an ID card reader/writer including an ID card, or a fingerprint reader, and 2 is an operator identification means, which performs operations based on operator identification data input from the data input means 1. Identify who the operator is. Reference numeral 3 is an operator file in which data regarding operators A, B, . . . , N who may operate the system is stored. In other words, in this operator file 3, there is a file area 3 related to operator A.
a File area 3b related to operator B,...
..., a file area 3n related to operator N, etc. This data regarding the operator includes information regarding the operator's level, proficiency, operation history, privilege level, etc., as well as a group of guidance messages for the operator and a group of parameters necessary to define the operating environment. In addition, the guidance message group for beginners includes, for example, a message to confirm whether or not it is okay to start the device, and a message to confirm whether or not the set rotation speed and time are within a certain tolerance range. On the other hand, a parameter group is not something that is displayed like a message, but rather a message that indicates whether a particular message can be ignored in the process of proceeding with the operation (for example, whether it is OK to ignore a particular message (proficiency level)). ).

Alternatively, it refers to matters that will be used as basis for judgment in the process of proceeding with an operation, such as matters agreed upon by the operator in a high-risk operation.

Reference numeral 4 denotes an environmental parameter storage means for reading and storing a guidance message group and a parameter group suitable for the operation of the operator based on the operator identification signal from the operator identification means 1. Reference numeral 5 denotes a supervisory control section which, based on the operator's operation data sent through the data input means 1, sends necessary guidance messages under the parameters stored in the environmental parameter storage means 4 on a CRT display or the like. It provides a procedure for proceeding with the operation while displaying the information on the display device 6, and also executes other processes necessary for monitoring and controlling the controlled object.

Next, the operation of the system configured as above will be explained. When operating the supervisory control system, when an operator inputs predetermined key data, ID number data, fingerprint data, etc. from the data input means 1, the operator identification means 2 receives this data and identifies which operator the operator is. It is identified as A. Here, when the environmental parameter storage means 4 receives the identification signal of the operator A from the operator identification means 2, the environmental parameter storage means 4 receives the identification signal of the operator A from the operator A data file area 3a, and selects an appropriate one based on data such as the operator A's level, proficiency, operation history, privilege level, etc. Select a group of guidance messages. If there are, for example, 100 types of guidance message groups, a high-level or experienced person may select, for example, about 20 types of guidance message groups, and then select a group of parameters necessary to define the operating environment. and store it in its own memory.

In this state, when operation data is input from the data input means 1 by an operator's operation, the monitoring control unit 5 reads appropriate parameters from the parameter group of the environmental parameter storage means 4 based on a predetermined program and sequentially sets the conditions. While determining this, necessary guidance messages are read out and displayed on the display device 6 to realize an operating environment.

Incidentally, when controlling the rotation speed of a motor, for example, after identifying the operator based on the operator identification data, a group of guidance messages and a group of parameters according to the operator's level etc. are read out from the file area of the corresponding operator, and the environmental parameters are adjusted. It is stored in the storage means 4. Thereafter, when the operator starts the operation, the monitoring control section 5 displays, for example, an image necessary for controlling the motor rotation speed on the display device 6 as shown in FIG. 2 (STI).

Thereafter, when the operator inputs the rotation speed of 80% via the data input means 1, the monitoring control unit 5 (Sr2)
In the next step ST3, it is determined whether the operator is a beginner. This judgment is made using a certain parameter in the environmental parameter storage means 4, and if you are a beginner, you can read out the corresponding guidance message, for example, ``The rotational speed is appropriate, and at that motor rotational speed, the discharge flow rate is 64%.'' (Sr4)
. Here, when the operator confirms the guidance message and inputs a "YES" response via the data input means 1 (Sr1), the supervisory control system responds with "YES".
After confirming the response "S", a command corresponding to 80% of the rotation speed is output (Sr1).If it is determined that the operator is an expert in step ST3, Sr4. It outputs a command equivalent to several 80%.

Next, FIG. 3 is a diagram showing a specific hardware configuration. In the figure, reference numeral 11 denotes an IC card reader/writer, which has a function of reading or writing the contents of the IC card 12. One IC card 12 is distributed to each operator, and in addition to an ID number for identifying the operator, data regarding the operator is stored as necessary. Therefore, in this case I
The C card 12 also serves as a part of the operator's file 3.

Reference numeral 13 denotes an auxiliary storage device which, in place of the IC card 12, stores data related to the operator as well as necessary program data, guidance messages, and parameters. Therefore, the CPU 1 serving as the monitoring control unit 5
4 identifies the operator from the ID number of the IC card 12, reads out a guidance message group and a parameter group from the auxiliary storage device 13 based on the identification signal, and stores them in the main storage device 15 as the environmental parameter storage means 4, for example. . 16 is a display device such as a CRT display for displaying plant status and messages; 17 is a process input/output device having an interface function with the plant 18;

Therefore, in the supervisory control system shown in FIG. 3 having the above configuration, when the operator inserts his own IC card 12 into the IC card reader 1 writer 11 at the start of operation, this IC card The reader/writer 11 reads the contents of the IC card 12. Here, C.P.
The U 14 reads out the ID number for identifying the operator, which is the contents of the IC card 12, as well as data related to the operator, such as the operator's level, proficiency, operation history, privilege level, etc. A guidance message group suitable for the operator is selected from the auxiliary storage device 13, an editing operation is performed to connect necessary messages of the guidance message group as necessary, and the edited message group is stored in the main storage device 15. The CPU 14 also reads out a group of parameters for defining the operating environment from the auxiliary storage device 13 and stores them in the main storage device 13.
Store in 5.

Therefore, after that, when the operator performs an operation necessary for control, the CPU 14 performs various judgments based on the program data stored in the auxiliary storage device 13 or the main storage device 15, while The guidance message group is read from the storage device 15, the monitoring control function is executed, and the processing results are displayed on the display device 16. Further, the CPU 14 can also collect the contents of the operator's operations as needed, and update the contents of the IC card 12 via the IC card reader/writer 11 as an operation history.

Next, FIG. 4 shows another embodiment of the same hardware configuration, in which a fingerprint reader 21 is used to identify the operator. In this case, data regarding the operator is stored in the auxiliary storage device 13. The other configurations and operations are as described above.

According to this embodiment, the operator is identified by taking a fingerprint, and the ID card 12 is stolen.

It is also effective in case of loss or miscarrying.

Note that in the above embodiment, files are filed separately for each operator in the operator file 3, but for example, guidance message groups and parameter groups may be filed without being separated for each operator, and messages can be stored based on operator identification signals or operator levels. The configuration may be such that the guidance message group and the parameter group are obtained by selectively extracting them as appropriate and editing them as necessary. Alternatively, a configuration may be adopted in which the guidance message group and the parameter group are simply selected depending on the operator, without considering the level of the operator. In addition, the present invention can be implemented with various modifications without departing from the gist thereof.

[Effect of the invention] As explained above, according to the present invention, each operator
Alternatively, you can proceed with the operation by creating an appropriate operating environment and dialogue environment depending on the level of the operator, proficiency of the system, etc.
be able to. As a result, for beginners, a wealth of helpful guidance messages are displayed, allowing them to perform safe and proper operations through multiple checks and confirmation steps.
On the other hand, in the case of an experienced user, the user can proceed with the operation by omitting operations that may be considered troublesome as much as possible, or by limiting the number of check and confirmation steps to a minimum, thereby realizing a speedy operating environment.
