Description
Technical Field
The present invention relates to an operation support system for an industrial plant.
Background
Industrial plants (plants) (steel plants, power plants, petroleum plants, chemical plants, etc.) are known which produce raw materials or resources required for industrial activities.

Disclosure of Invention
Problems to be solved by the invention
However, in the integrated diagnostic system of patent document 1, there is a possibility that the guidance displayed on the screen may be overlooked in a situation where the material state needs to be watched. As a result, it is possible that the malfunction is not noticed. Therefore, the operator is not sufficiently assisted by the guidance display alone.
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an operation support system for an industrial plant, which enables an operator with less experience to simulate an appropriate operation by a skilled person even in a situation where attention must be paid to the state of a material.
Means for solving the problems
In order to achieve the above object, an operation support system for an industrial plant according to the present invention is configured as follows.
An operation assistance system for an industrial plant is provided with an operation switch, a programmable logic controller, an assistance device, and a ring-type wearable device.
The operation switch transmits an input signal including an input value input by an operator.
The programmable logic controller is connected with the operation switch. The programmable logic controller controls the industrial plant based on the input signal. The programmable logic controller continuously transmits an operation signal concerning an operation state of the industrial plant to the auxiliary device.
The ring-shaped wearable device worn by the operator is wirelessly connected with the auxiliary device. The ring-type wearable device vibrates based on the auxiliary signal.
The auxiliary device is connected with the operation switch and the programmable logic controller. The auxiliary device has skilled operation information for associating the operation state of the industrial plant with an appropriate input value range of the operation switch. The auxiliary device calculates the current operation state of the industrial plant based on at least 1 operation signal. The auxiliary device extracts the appropriate input value range associated with the current operation state from the skilled operation information. In the case where the input value included in the input signal received from the operation switch is not included in the appropriate input value range, the auxiliary device transmits an abnormality signal as the auxiliary signal to the ring-type wearable device.
Effects of the invention
According to the industrial plant operation support system according to the present invention, when the operator performs an operation deviating from the appropriate input value range corresponding to the current operation state, the ring-shaped wearable device can be vibrated. By such force feedback, the operator can be more interactively and intuitively assisted by transmitting a stimulus to a tactile sensitive finger in a situation where the operator must be focused on the material state than in the case of transmitting the stimulus visually alone. In addition, it is also possible to transmit various information to the operator by wearing a ring-type wearable device having different actions on a plurality of fingers.
According to the present invention, an operator with little experience can simulate an appropriate operation corresponding to the current work state based on the default knowledge (intuition, gateway, and recipe) grasped by the skilled person. As a result, the product quality of the production line can be improved, the productivity can be improved, and the number of work accidents can be reduced.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, in the embodiments described below, when the number, the amount, the range, and the like of each element are referred to, the present invention is not limited to the number unless otherwise explicitly indicated or clearly determined as such in principle. Note that the structure and the like described in the embodiments shown below are not necessarily essential to the present invention, unless otherwise explicitly indicated or clearly determined in principle. In addition, the same reference numerals are given to the common elements in the drawings, and redundant description is omitted.
Embodiment 1.
(System constitution)
Fig. 1 is a configuration diagram of an operation support system for an industrial plant according to embodiment 1 of the present invention.
A plant monitoring and control system 1 of an industrial plant includes an actuator 2, an input/output device 3, a programmable logic controller 4 (hereinafter referred to as PLC 4), a computer network 5 (hereinafter referred to as network 5), an operation device 6, an auxiliary device 7, and a ring-type wearable device 8.
The connection relationship between the devices will be described. The actuator 2 is connected to the PLC4 via the input/output device 3. The PLC4 is connected to an operation device 6 and an auxiliary device 7 via a network 5. The operation device 6 is connected to the PLC4 and the auxiliary device 7 via the network 5. The auxiliary device 7 is connected to the PLC4, the operation device 6, and the ring-type wearable device 8 via the network 5. In particular, the auxiliary device 7 and the ring-type wearable apparatus 8 are connected wirelessly.
The actuator 2 is a motor, an electromagnetic valve, a hydraulic device, or the like constituting an industrial plant (for example, a steel plant).
The PLC4 receives an input signal 12 from the operation device 6, and controls the actuator 2 based on the input signal 12. The PLC4 continuously transmits an operation signal 11 concerning the operation state of the industrial plant to the auxiliary device 7.
The operation device 6 includes at least 1 of an operation panel 61 and a Human Machine Interface (HMI) device 62. The operation panel 61 includes an operation switch 60 as hardware. The HMI device 62 includes the operation switch 60 as software operatively displayed on the monitor. The operation switch 60 transmits an input signal 12 including an input value input by an operator operating in the industrial plant to the PLC4 and the auxiliary device 7.
The auxiliary device 7 receives the input signal 12 of the operation switch 60 and the operation signal 11 of the PLC 4. The auxiliary device 7 transmits an auxiliary signal 13 to the ring-type wearable apparatus 8 based on the input signal 12 and the job signal 11.
The ring-type wearable device 8 is a device for an operator to wear on the body, preferably a smart ring (smart ring) to be worn on a finger. The ring-type wearable device 8 receives the auxiliary signal 13 from the auxiliary apparatus 7, and vibrates based on the auxiliary signal 13.
The operation support system 10 for an industrial plant is realized mainly by cooperation of the PLC4, the operation switch 60, the support device 7, and the ring-shaped wearable device 8.
The support device 7 includes skilled operation information 70, a work state calculation unit 71, and a support processing unit 72, which will be described later. The skilled operation information 70 of the assisting device 7, the operation state calculating unit 71, and the assisting processing unit 72 function in cooperation with each other to transmit an assisting signal determined based on the skilled operation information 70 according to the current operation state to the ring-type wearable device 8. The auxiliary device 7 is realized by an expert system or a machine learning system, for example. For example, the expert system includes a knowledge base for converting professional knowledge into data, and an inference engine for deriving data that is considered to be a correct solution from data obtained from the knowledge base. Here, the knowledge base corresponds to the skilled operation information 70, and the inference engine corresponds to the work state calculation unit 71 and the support processing unit 72.
The assisting apparatus 7 of the present embodiment realizes 2 assisting functions. The 1 st assist function warns of an inappropriate operation of the operation switch 60 by the operator through force feedback. The No. 2 assist function urges the operator to start the operation of the operation switch 60 when the operation state of the industrial plant is close to the abnormal state.
(1 st auxiliary function)
First, a pair of configurations for realizing the above-described 1 st auxiliary function will be described.
The skilled operation information 70 is a set of information in which the operation state of the industrial plant is associated with an appropriate input value range of the operation switch 60. The skilled operation information 70 is information obtained by converting the knowledge of the skilled operator into data. The knowledge includes past actual data and operation history (operation timing and operation amount) that are considered to be high in stability and quality of the operation. That is, the appropriate input value range is data on the operation state of the operation switch 60 by a skilled operator corresponding to the operation state of the industrial plant. The skilled operation information 70 is used to calculate an appropriate input value range for each job status. The skilled operation information 70 is, for example, a knowledge base of an expert system in which knowledge of a skilled operator is stored, data obtained by machine learning using the operation of the skilled operator as teacher data, table data in which an operation state is associated with the knowledge of the skilled operator corresponding to the operation state, or the like.
The operation state calculation unit 71 calculates the current operation state of the industrial plant based on at least 1 operation signal.
The support processing unit 72 extracts an appropriate input value range associated with the current operation state from the skilled operation information 70. Next, the auxiliary processing unit 72 determines whether or not the input value included in the input signal received from the operation switch 60 is included in an appropriate input value range. Next, when the input value included in the input signal received from the operation switch 60 is not included in the appropriate input value range, the assist processing unit 72 transmits an abnormality signal as an assist signal to the ring-type wearable device 8. The ring-type wearable device 8 vibrates in response to the abnormal signal, stimulating the operator's sense of touch.
With this configuration, it is possible to determine whether or not the operation by the operator is appropriate in real time. When the operation switch 60 is operated beyond the appropriate input value range corresponding to the current operation state, it is possible to warn the operator of an excessive operation of the operation switch 60 by force feedback to the operator's sense of touch. In particular, in a situation where the guidance display is likely to be overlooked because the operator needs to be aware of the state of the material, it is possible to assist the operator with little experience in simulating the behavior of the appropriate operation by the skilled worker.
(auxiliary function 2)
Next, a configuration for realizing the 2 nd auxiliary function will be described with reference to fig. 1 and 2. The 1 st assist function described above assists the operator who is operating the operation switch 60. However, even in a situation where the operation switch 60 is not operated, it is desirable to call the operator attention to the start of the operation when the current working state is close to the abnormal state. Therefore, the 2 nd auxiliary function urges the operator to start the operation of the operation switch 60 when the operation state of the industrial plant is close to the abnormal state.
The skilled operation information 70 includes information (temporal change tendency of the work state, threshold value of a predetermined parameter) capable of determining whether or not the current work state is close to an abnormal state based on the stored work signal.
When the input signal is not received from the operation switch 60 for a predetermined time or more, the auxiliary processing unit 72 determines whether or not the current operation state of the industrial plant is close to the abnormal state.
For example, whether or not the current work state is close to the abnormal state can be determined based on whether or not a temporal trend based on the work state reaches the abnormal state within a predetermined time, whether or not a predetermined parameter exceeds a threshold value, or the like. When it is determined that the current working state is close to the abnormal state, the assist processing unit 72 transmits an abnormality prediction signal for prompting the operator to input to the operation switch 60 as an assist signal. The ring-type wearable device 8 vibrates in response to the abnormal prediction signal, stimulating the operator's sense of touch. In addition, the vibration pattern of the 2 nd auxiliary function is preferably a period different from that of the vibration pattern of the 1 st auxiliary function to distinguish the meaning of the vibration.
With such a configuration, as shown in fig. 2, even when the operator is in the non-operation state, the operator can analyze the trend of the change in the work state and transmit an assist signal for urging the start of the operation at a timing when the operation of the operation switch 60 is required. The assisting device 7 calls attention to the operator that the operation needs to be started by causing the ring-type wearable apparatus 8 to vibrate in a vibration mode corresponding to the 2 nd assisting function. In this way, the 2 nd assist function can assist a less experienced operator based on the knowledge of a skilled operator.
(treatment procedure)
The flow of processing for realizing the 1 st and 2 nd support functions will be described with reference to the flowchart of fig. 3. The 1 st auxiliary function is realized by the processing of step S100 to step S130. The 2 nd support function is realized by the processing of step S100, step S110, and step S140 to step S160. The process flow of fig. 3 is repeatedly executed.
The auxiliary device 7 continuously receives the operation signal from the PLC 4. In step S100, the auxiliary device 7 calculates the current operation state of the industrial plant based on the received operation signal and the operation state calculated in the past.
In step S110, the assist device 7 determines whether or not the operation switch 60 is operated by the operator. If the determination condition is satisfied, the process of step S120 is executed.
In step S120, the assist device 7 determines whether or not the input value included in the input signal received from the operation switch 60 deviates from an appropriate input value range. Specifically, first, the support processing unit 72 extracts an appropriate input value range associated with the current work state from the skilled operation information 70. Next, the auxiliary processing unit 72 determines whether the input value is out of the appropriate input value range. If the determination condition is satisfied, the process of step S130 is executed.
In step S130, the auxiliary device 7 transmits the abnormality signal 14 as the auxiliary signal 13 to the ring-type wearable apparatus 8 (fig. 4). The ring-type wearable device 8 receives the anomaly signal 14 from the auxiliary apparatus 7. The ring-type wearable device 8, upon receiving the abnormality signal 14, vibrates in the alert mode 15 (1 st mode) (fig. 4). Then, the process of step S100 is executed again.
When the determination condition in step S120 is not satisfied, the operation by the operator is appropriate. In this case, the auxiliary signal is not transmitted, and the process of step S100 is performed again.
On the other hand, if the determination condition in step S110 is not satisfied, the process in step S140 is executed.
In step S140, the assist device 7 determines whether or not there is no input by the operator for N seconds or longer. When no input signal is received from the operation switch 60 for N seconds or longer, the auxiliary processing unit 72 executes the processing of step S150. If the determination condition in step S140 is not satisfied, the process in step S100 is executed again.
In step S150, the support device 7 determines whether or not it is necessary to urge the operator to start the operation. The support processing unit 72 determines whether or not the current operation state of the industrial plant is close to an abnormal state based on the skilled operation information 70. If the determination condition is satisfied, the process of step S160 is executed.
In step S160, the assist device 7 transmits the abnormality prediction signal 16 (fig. 4) urging the operator to input to the operation switch 60 to the ring-type wearable device 8 as the assist signal 13. The ring-type wearable device 8 receives the abnormality prediction signal 16 from the auxiliary apparatus 7. The ring-type wearable device 8, upon receiving the abnormality prediction signal 16, vibrates in the notification mode 17 (2 nd mode of a cycle different from that of 1 st mode) (fig. 4).
When the determination condition in step S150 is not satisfied, the assist signal is not transmitted, and the routine is once ended and executed again in the next control cycle.
As described above, according to the operation support system 10 for an industrial plant of the present embodiment, it is possible to support an operator with little experience based on the knowledge of a skilled operator by the 1 st support function and the 2 nd support function described above. Therefore, even an operator with little experience can simulate an appropriate operation of a skilled person according to the current work state. As a result, the product quality of the production line can be improved, the productivity can be improved, and the number of work accidents can be reduced.
(modification example)
In the present embodiment, both the 1 st auxiliary function and the 2 nd auxiliary function are provided, but only one of the functions may be provided.
(Rotary switch)
The system of the present embodiment is basically the same as embodiment 1 except for the following configurations of the operation switch 60 and the auxiliary device 7 shown in fig. 1.
In the present embodiment, the operation switch 60 is the rotary switch 20, and the input value of the operation switch 60 is a rotation angle value. The rotary switch 20 transmits an input signal 12 including a rotation angle value corresponding to an operation by an operator.
The appropriate input value range 21 of the skilled operation information 70 described above includes the rotation angle threshold value 22 of the rotary switch 20. That is, the skilled operation information 70 includes a set of information in which the operation state of the industrial plant is associated with the rotation angle threshold 22 of the rotary switch 20.
The support processing unit 72 of the support device 7 extracts the rotation angle threshold 22 associated with the current work state from the skilled operation information 70.
Next, the assist processing unit 72 determines whether or not the rotation angle value included in the input signal 12 received from the rotary switch 20 is within the rotation angle threshold value 22.
Next, when the rotation angle value included in the input signal 12 received from the rotary switch 20 exceeds the rotation angle threshold, the assist processing unit 72 transmits the abnormality signal 14 (fig. 4) to the ring-type wearable device 8 as the assist signal 13. The ring-type wearable device 8 vibrates according to the abnormality signal 14, stimulating the tactile sensation of the operator.
For example, as shown in fig. 5, in a case where the rotation angle value of the rotary switch 20 is included in the appropriate input value range 21, the ring-type wearable device 8 does not vibrate. On the other hand, the ring-type wearable device 8 vibrates from the time when the rotation angle value of the rotation switch 20 exceeds the rotation angle threshold 22. Thus, the force feedback is used to alert the operator of improper operation. Therefore, the rotary switch 20 can be suppressed from being operated out of the appropriate operation range.
Embodiment 3.
(momentary switch)
Embodiment 3 of the present invention will be described with reference to fig. 1 and 6. Fig. 6 is a diagram for explaining an example of operation assistance of the push-push type momentary switch by the ring-type wearable device according to embodiment 3 of the present invention.
The system of the present embodiment is basically the same as that of embodiment 1 except for the following configurations of the operation switch 60 and the auxiliary device 7 shown in fig. 1.
In the present embodiment, the operation switch 60 is a push-type momentary switch 30, and the input value of the operation switch 60 is an ON value. The push-type momentary switch 30 transmits an input signal 12 containing an ON value during the period of depression by the operator.
The appropriate input value range of the above-described skilled operation information 70 includes the ON value duration allowance period of the push type momentary switch 30. That is, the skilled operation information 70 includes a set of information in which the operation state of the industrial plant is associated with the ON value continuation permission period of the push-type momentary switch 30.
The support processing unit 72 of the support device 7 extracts the ON value continuation permission period associated with the current work state from the skilled operation information 70. In the example shown in fig. 6, the ON value continuation permission period is a period from time T1 to time T2.
Next, the auxiliary processing unit 72 determines whether the input signal 12 including the ON value has been continuously input from the push-type momentary switch 30 over the ON value continuation permission period.
When the input signal 12 including the ON value is continuously input from the push-type momentary switch 30 during the ON value continuation permission period, the auxiliary processing unit 72 transmits the abnormality signal 14 (fig. 4) to the ring-type wearable device 8 as the auxiliary signal 13.
For example, in the example shown in fig. 6, the ON value continuation permission period is a period from time T1 to time T2. When the input signal 12 including the ON value is continuously input beyond the time T2, the ring-type wearable device 8 vibrates from the time exceeding the time T2. Thus, force feedback is used to alert the operator of improper operation. Therefore, the push-type momentary switch 30 can be suppressed from being operated out of the appropriate operation range.
(modification example)
Incidentally, in the system of embodiment 3 described above, the push-push type momentary switch 30 is used as the operation switch 60. However, as shown in fig. 7, a toggle momentary switch 31 may be used as the operation switch 60.
Embodiment 4.
(alternating switch)
Embodiment 4 of the present invention will be described with reference to fig. 1 and 8. Fig. 8 is a diagram for explaining an example of operation assistance of the push-type alternation switch by the ring-type wearable device according to embodiment 4 of the present invention.
The system of the present embodiment is basically the same as embodiment 1 except for the following configurations of the operation switch 60 and the auxiliary device 7 shown in fig. 1.
In the present embodiment, the operation switch 60 is a push-type alternating switch 40, and the push-type alternating switch 40 alternately transmits the input signal 12 including an ON value and the input signal 12 including an OFF value every time the operator presses it.
The appropriate input value range (appropriate input value data) of the above-described skilled operation information 70 includes an appropriate state value (ON value or OFF value) of the push type alternate switch 40. That is, the skilled operation information 70 includes a set of information that associates the operation state of the industrial plant with an appropriate state value (ON value or OFF value) of the push-type alternation switch 40.
The support processing unit 72 of the support device 7 extracts an appropriate state value (ON value or OFF value) associated with the current work state from the skilled operation information 70. In the example shown in fig. 8, the appropriate state value of the push-type alternate switch 40 is the OFF value before and after time T3.
Next, the assist processing unit 72 determines whether or not the state value (ON value or OFF value) included in the input signal 12 received from the push-type alternating switch 40 matches an appropriate state value.
Next, when the input signal 12 received from the push-type ac switch 40 contains an ON value and the appropriate state value is an OFF value, the assist processing unit 72 transmits the abnormality signal 14 as the assist signal 13 to the ring-type wearable device 8 (fig. 4). Further, when the input signal 12 received from the push-type alternation switch 40 includes an OFF value and the appropriate state value is an ON value, the assist processing unit 72 transmits the abnormality signal 14 to the ring-type wearable device 8 as the assist signal 13.
For example, in the example shown in fig. 8, the push-type alternate switch 40 is pushed by the operator at time T3 and outputs the input signal 12 including the ON value. On the other hand, at time T3, the appropriate state value is an OFF value. That is, the operation by the operator at time T3 is inappropriate. Therefore, the ring-type wearable device 8 vibrates from the time T3. This warns the operator of inappropriate operation using force feedback. Therefore, the push-type momentary switch 30 can be suppressed from being operated out of the appropriate operation range.
(modification example)
In the system according to embodiment 4 described above, the push-type alternate switch 40 is used as the operation switch 60. However, as shown in fig. 9, a toggle type alternate switch 41 may be used as the operation switch 60.
(executive switch)
The system of the present embodiment is basically the same as that of embodiment 1, except that the operation device 6 shown in fig. 1 includes the setting switch 51, and the following configuration regarding the operation switch 60 and the auxiliary device 7.
The setting switch 51 can input a setting value. In the present embodiment, the operation switch 60 is the execution switch 50. The execution switch 50 is pressed by the operator, and transmits an input signal 12 including a set value input to the setting switch.
The appropriate input value range (appropriate input value data) of the skilled operation information 70 includes an appropriate value range of the set value input to the setting switch 51. That is, the skilled operation information 70 includes a set of information in which the operation state of the industrial plant is associated with the appropriate value range of the set value input to the setting switch 51.
The support processing unit 72 of the support device 7 extracts an appropriate value range associated with the current work state from the skilled operation information 70.
Next, the auxiliary processing unit 72 determines whether or not the set value included in the input signal 12 received from the execution switch 50 is included in the appropriate value range.
Next, the auxiliary processing unit 72 transmits the abnormality signal 14 as the auxiliary signal 13 to the ring-type wearable device 8 when the set value included in the input signal 12 received from the execution switch 50 is not included in the appropriate value range (fig. 4).
Fig. 10 shows an example in which the execution switch 50 is pressed at time T4 although the setting value input to the setting switch 51 is not appropriate. In this case, the operation by the operator at time T4 is inappropriate. Therefore, the ring-type wearable device 8 vibrates from the time T4. This warns the operator of an inappropriate operation using the force feedback. Therefore, it is possible to suppress the execution switch 50 from being continuously operated in a state where the set value is inappropriate.
