Description

A device and method for visual display of module status in the control system {APPARATUS AND METHOD FOR DISPLAYING THE STATE OF MODULES VISUALLY IN THE CONTROL SYSTEM}

The present invention relates to an apparatus and method for visually displaying the state of each module of a controlled object in a control system that manages and controls electronic, mechanical, or architectural civil purpose devices and facilities through a network, and more specifically, within the target device In response to the result of performing the status diagnosis for each of the plurality of modules, the status diagnosis screen is a combination of a plurality of status images that have a shape and location similar to that of each module, but display corresponding to the level corresponding to the diagnosis status of each module. It relates to a module status visual display device and method in the control system for displaying.

With the development of electronic technology and communication technology, products, equipment and facilities used in the whole society, furthermore, the entire building, transportation means such as vehicles, railroads, ships, aircraft, or various safety facilities such as elevators and escalators, Built-in self-diagnosis system is installed, and through wired or various wireless networks such as directly connected data lines or network lines, it predicts or diagnoses the failure of the relevant equipment, and if a failure is predicted or a failure occurs, wired or There is a trend of widespread use of a fault diagnosis system that generates a fault warning in a control center connected by wireless and a control system that includes it.

For example, in the case of a factory with large mechanical facilities such as various manufacturing facilities and transport facilities, such as a factory that produces products, or a large building with a huge number of various equipment or facilities built into the building, in order to manage the whole with a limited number of people, Control devices such as PLC (Programmable Logic Controller) or DDC (Direct Digital Controller) to control the facility are becoming essential elements.

In addition, control devices for various facilities such as air conditioning (HAVC; Heating, Ventilation, Air-Condition), power, lighting, elevators, escalators, and fire alarms are essential elements. This is an integral part of the entire building for efficient management. The integrated control system that can be managed in is widely used.

In this regard, thanks to the development of various electronic devices and network communication, the number of control points installed in devices or facilities is increasing tremendously, and as the automation of factories is also expanded, the installation of various equipment necessary for automation facilities is increasing. , The control point is increasing remarkably, and the importance of the control is also increasing.

Therefore, in order to easily manage and control the subject of control, which is becoming more complex and diversified, it is very important to increase the visibility of the manager, but in the existing control system, data is appropriately visualized by focusing on data visualization and analysis (Pie Chart, Line Chart, Gauge, etc.), and has been developed with a focus on display and analysis, and WYSIWYG (What You See Is What: What You See Is What) can visualize the location of equipment in the factory or intuitively grasp the location of IOT equipment and equipment in the farm. The control screen with the effect of You Get) was relatively poorly developed.

In addition, in the control screen display stage, the control screen must be able to control the situation by controlling the terminal equipment through commands such as clicking a visual element, manipulating a switch, or selecting a list, or executing a specific query. This should be expandable by allowing the expansion of commands and accompanying actions to be set arbitrarily. For example, you should be able to start or stop certain equipment at the push of a button, and you should be able to take action when a failure occurs and then end the failure situation.

However, most data visualization tools do not take into account the function for control. In the case of a tool that interlocks and controls devices, it is limited to compatible devices or provided in the form of a list, so it does not deal with the creation of the control screen. In addition, as the demand for the proliferation of mobile devices, remote monitoring, and immediate response in the event of a failure from static screens with an exhibition purpose, such as a factory dashboard or a dashboard in the field of infrastructure resource monitoring, is increasing, the display of the control screen is limited in place. It should be able to be used without this.

Referring to the prior art document cited in the present application as a prior art, that is, Patent Publication 10-2018-0012613 (published on February 6, 2018) "Smart Factory Work Environment Control System", smart factory work according to the prior art As shown in FIG. 1, which is a configuration diagram of the environment control system, the entrance and exit of an object to the surveillance area can be detected using a lighting sensor 300, a motion detection sensor 200, etc., and a surveillance camera installed in the surveillance area (100) discloses a technology for controlling the illuminance of lighting located around an object in real time through object tracking so that a surveillance image can be collected when an object is detected. In addition, in the prior art literature, it is said that system errors or equipment failures in factories and production facilities can be identified through intelligent image processing, and thus, in the case of system errors or equipment failures, the cause can be quickly diagnosed to prevent loss of sales.

That is, referring to FIG. 2, which is an exemplary diagram of a control screen used in a smart factory work environment control system according to the prior art, while selecting and controlling a monitoring camera to be monitored with a monitoring camera selection button and a monitoring camera control button, monitoring the monitoring camera It is to check the image collected from the surveillance camera 100 through the screen.

However, the above-described conventional technology collects surveillance images taken by a plurality of cameras installed in a fixed place, and it is not possible to visually check the abnormality of a module in which a failure or error occurred, and the image is checked by a surveillance camera. Even so, it is difficult to visually and easily check in which module an error has occurred. That is, even if the camera can refer to the image taken outside, it is not possible to intuitively grasp the failure of a component built into the external cable by the shape of the faulty component.

In addition, the prior art 1 above collects surveillance images when an object is detected, and even if a device in which a malfunction occurs is checked with a surveillance camera, it is difficult to prevent a malfunction because it only deals with the process after the malfunction occurs. .

In addition, if there are other parts related to the failure in connection with the part where the actual failure occurred, only the repaired part will be repaired and the related parts will not be inspected. Therefore, even after repair, there is a possibility that the failure may recur, but there is no way to prevent this.

First, the control device 1100 is provided in a separate space located remotely from the target device 1300 and controls the overall operation of the target device 1300 through the network 1200, and includes a desktop PC, a tablet PC, and a smart device. It may include phones, notebooks, laptop computers, monitors, TVs, and the like.

The operator input unit 1110 of the control device 1100 is composed of an input device known in existing computers or mobile-based electronic systems such as a keyboard, a mouse, a touch pad, a touch pen, and a touch screen, and data corresponding to each key of the keyboard , Data corresponding to the amount of movement and direction of movement according to mouse operation, data corresponding to the contact position or contact strength or the direction of movement after contact by a touch pen or a touch pad are input in the form of an electrical signal and converted into a corresponding data code. , Applied to the control control unit 1120.

For example, when the manager of the control device 1100 inputs a command for condition diagnosis through the operator input unit 1110, the operator input unit 1110 transmits command data corresponding to the command to the control control unit 1120 in the form of an electrical signal. do.

In addition, when the manager of the control device 1100 selects a status image in the status display screen through the operator input unit 1110, a link connection command corresponding to the status image is transmitted to the control control unit 1120.

In addition, the control control unit 1120 provides a procedure corresponding to the command or data input through the operator input unit 1110 or the control communication module 1150 in a pre-stored command set in the form of a program or application in the data storage unit 1130.

From the plurality of levels of module status information stored in the module, the status level for each module is determined, and the status image data corresponding to the determined status level is retrieved from the control data storage unit 1130, corresponding to each of the plurality of modules. A plurality of state images are combined to form a state display screen. Then, the display unit 1140 is controlled to display the status display screen.

In this case, the control control unit 1120 may place the state image at an accurate location by using canvas-based X and Y coordinates. The control control unit 1120 supports a zoom function and may be displayed while maintaining a ratio even if the resolution is different from the produced resolution.

Each of the plurality of module agents 1330a, 1330b, ..., 1330n may include a sensor (not shown) for diagnosing a condition for each corresponding module 1340a, 1340b, ..., 1340n, for example, a temperature sensor , Rotation detection sensor, moisture detection sensor, contact failure detection sensor, fuel detection sensor, voltage/current detection sensor, oxygen sensor, people counting sensor, GPS sensor, infrared sensor, geomagnetic sensor, and the like. In addition, the type of sensor is not necessarily limited thereto.

In addition, in some embodiments of the present invention, at least one of the plurality of module agents 1330a, 1330b, ..., 1330n resides in a local area rather than a public network section, so that equipment and DB connection information are not exposed to the network section. It is processed as a resource and can be exchanged in a secure section without exposing the format, thereby improving security. In addition, the agent can simultaneously perform a role as a data collection unit and a control unit. First, the role of the data collection unit accesses the DB through a registered action command to perform a query or retrieves data through CLI script execution, and processes it into a resource of a consistent format to utilize it. The role of the control unit is to execute an execution command (Action) through a registered trigger processing module according to the resource value update, and perform equipment control through a database update method such as script execution.

The module 1340 is referred to as a "module" for convenience, but may be various devices or facilities such as escalators, elevators, air conditioning systems, lighting, fire alarms, gas alarms, or electrical or mechanical equipment constituting each device or facility. In this case, each module is preferably a module that can be replaced and repaired when a failure occurs. In this case, the control operator can easily check the corresponding module, check the part model number, etc., and have the effect of being able to easily and quickly replace the faulty part.

Hereinafter, a method of visually displaying a module status in a control system according to a preferred embodiment of the present invention will be described with reference to FIG. 4.

4 is a detailed flowchart of a method for visually displaying a module status in a control system according to an embodiment of the present invention.

In this embodiment, as a table shown in FIG. 5 to aid understanding of the present application, examples of the state level and the aging standard range are given, but this is a simplified example for explanation, and the types of devices and parts, design intention It can be set in various ways based on various factors, such as the precision of management requirements.

A method for visually displaying module status in a control system according to a preferred embodiment of the present invention is a program or application composed of a set of pre-organized electronic data that can be recognized by computers, smartphones, and other electromechanical devices. , A PC, a server, a smartphone, or other electronic device, and the like, can visually or aurally output a corresponding result through data processing based on input commands and data according to a preset procedure.

First, a preset status display screen is displayed on the display unit 1140. In this case, the status display screen displayed on the display unit 1140 may be a status display screen configured in a previous step, that is, a status display screen configured by a result of a previous status diagnosis (S110).

On the other hand, the device control unit 320 of the target device 1300 diagnoses the status of the corresponding module among the plurality of modules 1340a, 1340b, …, 1340n, each of the plurality of module agents 1330a, 1330b, …, 1330n. It waits for whether a predetermined time interval for this has arrived or whether a condition diagnosis command from the control device 1100 is received (S10).

In step S10, when a predetermined time interval for diagnosing a condition arrives, or when a condition diagnosis command from the control device 1100 is received, the device control unit 1320 includes a plurality of modules 1340a, 1340b, ..., 1340n. A plurality of module agents 1330a, 1330b, ..., 1330n are controlled to perform a state diagnosis on the.

The plurality of module agents 1330a, 1330b, ..., 1330n, under the control of the device controller 1320, have a temperature sensor, a rotation detection sensor, a moisture detection sensor, a contact failure detection sensor, a fuel detection sensor, and voltage/ Using at least one or a combination of two or more of sensors such as a current detection sensor, an oxygen sensor, a people counting sensor, a GPS sensor, an infrared sensor, a geomagnetic sensor, etc., for a plurality of modules 1340a, 1340b, ..., 1340n. Perform a condition diagnosis. And, when the condition diagnosis result is transmitted to the device control unit 1320, the device control unit 1320 converts the different diagnosis results of each of the plurality of modules 1340a, 1340b, ..., 1340n into condition diagnosis data in a common standard data format. Then, it is transmitted to the device communication module 1310. The device communication module 1310 standardizes the condition diagnosis data from the device control unit 1320 according to the standard of the network 1200, and then communicates to the control communication module 1150 in the control device 1100 through the network 1200. It transmits (S20).

The control communication module 1150 restores the condition diagnosis data received from the target device 1300 through the network 1200 to the condition diagnosis data before communication standardization, and then transmits it to the control control unit 1120.

The control control unit 1120 stores condition diagnosis data for each of the plurality of modules 1340a, 1340b, ..., 1340n, based on the condition diagnosis data received from the control communication module 1150, in the control data storage unit 1130. Retrieve status information. For example, the condition diagnosis data for each of the plurality of modules 1340a, 1340b, ..., 1340n is searched from the table shown in FIG. 5, and the status diagnosis data is in which module state. In this embodiment, the control control unit 1120 first determines whether the condition diagnosis data is in an abnormal state. That is, taking the module A 1330a as an example, it is determined whether the condition diagnosis data is equal to or greater than f (f≦status diagnosis data) (S120).

In step S120, if the condition diagnosis data of the module A 1330a is f or more (f≦status diagnosis data), the control control unit 1120 stores the abnormal condition image data for the module A 1330a into the control data storage unit 1130. From, the abnormal state image corresponding to the data searched for the module A 1330a is mapped (S130).

In this case, the abnormal state image may have the same shape as the module A, but may be a state image that is emphasized in red, and in the case of black and white, it may be filled with black with the highest shade. Such an abnormal state image can be variously modified according to the designer. In addition, when there is a module in an abnormal state, the control control unit 1120 may be configured to control the control device 1100 that generates a warning sound from an unillustrated voice output unit when a status display screen is output.

Accordingly, due to the abnormal state image displayed in the same shape and highlighted color (or pattern), the manager of the control device 100 can intuitively and easily identify the occurrence of the abnormality and take a quick action. As a result, there is an effect of minimizing damage cost and loss for an abnormality that has already occurred.

Steps S120 and S130 described above are repeatedly performed for all modules 1340a, 1340b, ..., 1340n in the target device 1300. In another embodiment of the present invention, not only step S130, but also the entire process from step S130 to S180 to be described later may be configured to be repeatedly performed for all modules 1340a, 1340b, ..., 1340n in the target device 1300. have.

On the other hand, in step S120, if the condition diagnosis data of the module A 1330a is smaller than f (status diagnosis data <f), the control control unit 1120 determines whether the condition diagnosis data of the module A 1330a is between e and f. (e≦status diagnosis data<f) is determined (S140). That is, it is determined whether the module A 1330a is in the state of the warning level (S140).

In step S140, if the condition diagnosis data of the module A 1330a is not between e and f (e> condition diagnosis data), the control control unit 1120 stores the steady state image data for the module A 1330a into the control data storage unit. By searching from 1130, a steady state image corresponding to the data searched for module A 1330a is mapped (S150). At this time, since it has already been determined that the state diagnosis data is not larger than f in step S120, the state image of the module A 1330a is specified to be smaller than e and is determined to be in a normal state, and further explanation is omitted, but in FIG. As in the illustrated example, the normal state may also be classified into a plurality of levels and displayed more finely. It can be subdivided into one or more levels depending on the required control precision.

In addition, similar to S120 and S130 described above, steps S140 and S150 may be repeatedly performed for all modules 1340a, 1340b, ..., 1340n in the target device 1300. In addition, not only steps S140 and S150, but also the entire process from step S130 to S180 to be described later may be repeatedly performed for all modules 1340a, 1340b, ..., 1340n in the target device 1300.

On the other hand, in step S140, if the condition diagnosis data of the module A 1330a is between e and f (e ≤ condition diagnosis data <f), the control control unit 1120 again attenuates the condition diagnosis data of the module A 1330a. It is determined whether the deviation is greater than or equal to a preset threshold. That is, it is determined whether the condition diagnosis data of module A 1330a is within the standard attenuation range over time of module A 1330a (S160). For example, some of the devices subject to control of the control system deteriorate in performance depending on the usage period.For example, if the usage period of the module A 1330a is over 1 year, a warning set between e and f The state range may be between e1 and f1 deteriorated by a predetermined ratio (eg, 10%). In this case, e1=2×0.9 and f1=f×0/9, which are examples only to help understanding, and since the deterioration characteristics of each module are different, the standard range of aging reduction is set to an appropriate value for each module. Can be.

As a result of the determination in S160 described above, if the attenuation deviation of the condition diagnosis data of the module A 1330a is equal to or greater than a preset threshold, that is, if it is not within the standard attenuation range over time of the module A 1330a (e.g., f1<state Diagnostic data), the control control unit 1120 determines that the module A 1330a is in a warning state out of deterioration due to natural deterioration, that is, an abnormality such as a failure has not occurred, but is a warning state in which an abnormality is expected. , The abnormal predicted warning state image data for the module A 1330a is retrieved from the control data storage unit 1130, and an abnormal predictive warning state image corresponding to the data retrieved for the module A 1330a is mapped (S170). In this case, the control control unit 1120 may be configured to control the control device 1100 that generates a warning sound from an unillustrated voice output unit when outputting a status display screen, similar to the case where there is a module in an abnormal state. As a result, it is possible to take preliminary measures for modules displaying an abnormal warning state image before a failure occurs, ensuring safety compared to follow-up measures after an abnormality occurs, and management cost of the control target device. And labor can be significantly reduced. In addition, since such an abnormality predictive warning state is not expected to occur naturally due to deterioration, an abnormality occurs in the associated module according to the warning state, or such a warning state occurs in the module associated with the module in which a specific abnormality has occurred. As a result, there is a remarkable effect in preventing recurrence of a faulty module in advance.

As a result of the determination in S160 described above, if the attenuation deviation of the condition diagnosis data of the module A 1330a is less than a preset threshold, that is, in the standard attenuation range over time of the module A 1330a (e.g., e1≤state If diagnostic data <f1), the control control unit 1120 determines that the module A 1330a is in a deteriorated state due to natural deterioration, and stores the image data of the old warning state for the module A 1330a to the control data storage unit 1130. From, the old warning state image corresponding to the data searched for the module A 1330a is mapped (S180). In this case, as described in step S150, as in the example shown in FIG. 5, the old warning state may also be classified into a plurality of levels and displayed in more detail. It can be subdivided into one or more levels depending on the required control precision. As a result, for example, non-business hours, non-operating hours of equipment, inspection, repair, replacement, etc. are easy, and no cost is incurred, that is, non-operating, non-operating, non-operating, non-operating hours Proactive action can be taken during operating time.

Therefore, compared to taking follow-up measures after a module failure, it is possible to take preliminary measures in a spare time while securing certain safety, thereby enabling optimal maintenance and control in terms of cost and efficiency.

When the above-described process for all of the plurality of modules 1340a, 1340b, ..., 1340n in the target device 1300 is completed, the control control unit 91120 is all modules mapped to any one of the above-described steps S130, S150, S170, and S180. The display unit 1140 is controlled to configure the entire status display screen by combining the status images of and to display the configured status display screen.

As a result, the display unit 1140 displays the module status display visually expressed in an intuitive shape and color, and optionally a pattern, for each of the modules 1340a, 1340b, ..., 1340n in the target device 1300 ( S190).

In some embodiments of the present invention, when configuring the status display screen, the control control unit 1120 includes a control data storage unit in the status information corresponding to each module, in particular, in the status display image of the module in abnormal status or warning status. 1130), when the link display with the link activated is included in the detailed table, and when the corresponding link display is selected from the operator input unit 1110, the display unit 1140 is controlled to display information corresponding to the link. May be. In this case, there is an effect that the manager can accurately and easily grasp the action for the state of each module and respond accurately and quickly.
