1 is a diagram for conceptually explaining a system to which a general-purpose controller for control and measurement according to an embodiment is applied.

As shown in FIG. 1, the system of one embodiment basically monitors several management targets (facility or device), and the manager device 100 and Since measurement service is performed in conjunction with each other, the management target is maintained.

In this case, the system of one embodiment integrally collects the state data of the management target from the general-purpose controller 300 for control and measurement, for example, pressure or temperature from various types of analog and digital sensor devices, generates measurement results, This is done because it is provided to the manager device 100 .

In addition, when the measurement results are generated, these systems integrally and differently perform control according to the measurement results for various types of analog and digital control devices, so the measurement controller itself provides an integrated control service.

At this time, since the control controls, for example, the operation of the fine dust reduction device according to the fine dust measurement result or the operation of the blower according to the temperature measurement result, the control service is directly provided by the measurement controller using the measurement result. It is done.

Additionally, the system pre-registers corresponding signal interface information for each control type for each different control device and for each data type for each sensor device, and integrally processes I/O with the signal interface information for each different device.

And, at this time, since the signal interface with various sensor devices is switched for each of a number of different measurement services, for example, a service for measuring physical quantities of pressure or temperature, or a service for measuring electrical quantities, etc., I/O is diversified in a kind of network method. .

In addition, when I/O is diversified in this way, since signal interface information is extracted from an I/O port table in which signal interface information is mapped for each of a number of different control devices and sensor devices, control and measurement are integrated for general purpose. .

Additionally, a basic configuration applied to the system of this embodiment will be described below.

First, the system largely includes a manager device 100, a network switch 200, and a general-purpose controller 300 for control and measurement.

Here, when the manager device 100 monitors the management target, the operation of the control device connected to the general-purpose controller 300 for control and measurement is different from event information (eg, high pressure) based on schedule information or measurement results Since it is controlled indirectly, the facility environment is maintained in a normal state.

In addition, when the measurement result is received from the general-purpose controller 300 for control and measurement, the network switch 200 switches and relays the corresponding signal to the manager device 100 based on pre-registered network information. In addition, when the network switch 200 receives a control signal from the manager device 100, it switches the corresponding signal through the network information and relays it to the general-purpose controller 300 for control and measurement.

In addition, when the control signal is transmitted through the network switch 200, the general-purpose controller 300 for control and measurement directly and differently controls the operation of the control device in charge according to the control signal, so that the measurement According to the result, that is, the control device is driven according to the current state.

On the other hand, in addition, when the measurement result is transmitted from the general-purpose controller 300 for control and measurement, the system of one embodiment wirelessly provides the corresponding signal to the mobile terminal as another example of the manager device, so that the manager who travels to various places can measure smoothly. Include the WiFi AP for which the results are provided.

So, through this, when the system according to one embodiment monitors the management target, by controlling the operation of the control device differently from the above wireless configuration at a remote location, the manager can conveniently control according to the measurement results in various time zones and places. perform smoothly

2 is a diagram showing a system as a whole to which a universal controller for control and measurement according to an embodiment is applied.

As shown in FIG. 2, the system of one embodiment includes a plurality of general-purpose controllers for control and measurement (300-1 to 300-n) for measuring the state of a management target having a plurality of different types, and signals according to each measurement result. and a network switch 200 for switching and a manager device 100 at a remote location.

For example, when the measured pressure is higher than a preset reference pressure, the rotational operation of the compressor is lowered according to the difference between the two pressures, so the management target is self-maintained. In addition, in this case, the plurality of general-purpose controllers 300-1 to 300-n register signal interface information corresponding to control types for each of a plurality of different control devices and data types for each sensor device in advance. , I/O is processed integrally with signal interface information for each different device. And, at this time, since the signal interface with various sensor devices is switched for each of a number of different measurement services, for example, a service for measuring physical quantities of pressure or temperature, or a service for measuring electrical quantities, etc., I/O is diversified in a kind of network method. . In addition, when I/O is diversified in this way, since signal interface information is extracted from an I/O port table in which signal interface information is mapped for each of a number of different control devices and sensor devices, control and measurement are integrated for general purpose. .

When the manager device 100 receives measurement results from the plurality of general-purpose controllers 300-1 to 300-n through its own network, it is based on the control information for each state of the management target set in advance as a reference value. As it checks the status of the current management target, it monitors the management target. For example, when the pressure values provided from the plurality of general-purpose controllers 300-1 to 300-n are higher than the preset reference pressure value of the management target, it is confirmed that there is an abnormality in the management target. In this case, the manager device 100 controls the operation of the control device connected to the corresponding universal controller for control and measurement differently according to the state of the current management object, thereby maintaining the management object as a whole.

In addition, the DO module also integrally outputs digital control signals according to each of the measurement data collected by the AI module and the DI module to a plurality of different digital control devices under the control of the CPU module (S404, S407). In this case, the DO module outputs in the same way as the operation of the AO module.

On the other hand, when analog measurement data is collected from the AI module, for signal operation, etc., the A/D module converts the analog signal including the analog measurement data from the AI module into a digital integral under the control of the CPU module. convert to signal

To this end, the CPU module performs the following operations.

a) First, the CPU module extracts each measurement pattern based on the corresponding measurement characteristics for each of a plurality of different sensor devices, predicts measurement data in advance for each of a plurality of different measurement patterns, and registers matching.

b) Next, when the measurement data is collected, a measurement pattern is extracted based on a change in actual measurement data.

c) Therefore, the extracted measurement pattern is compared with the corresponding pre-registered measurement pattern.

d) As a result of the comparison, when the difference between the extracted measurement pattern and the pre-registered measurement pattern falls within a preset range, an alarm is not provided to the pre-registered management device, and when it does not fall within the preset range, provide an alert.

Additionally, when an alarm is provided in this way, the CPU module secures a real-time connection with the management device, so that related information is quickly and easily delivered to the manager.

To this end, the CPU module concurrently performs the following operations.

Then, the preprocessed result is stored.

Then, the measurement data is learned for each of a plurality of different management objects, and the required time and measurement data for each unit measurement task are predicted for each different model from the learning results to generate a predictive data model.

In this case, the predictive data model is made as follows.

a) First, the prediction data model is divided into a data period and a holding period for each of a plurality of different management objects, and a required time and measurement data learning model are defined.

d) Then, determine the required time and properties of the measurement data for a number of different models.

e) So, normalization data is generated from the determined result.

f) Next, set independent and dependent variables by setting the time required for each unit measurement task and measurement data for each model.

h) Then, learning and training data are generated for the set result.

i) Therefore, a data prediction model is created as a deep learning-based learning model from the result generated in this way.

In this state, state data is collected as a whole for each different management subject, and the required time and measurement data are confirmed.

Next, the required time and measurement data are compared with the previously predicted required time and measurement data of the model.

As a result of the comparison, for example, when the difference between the two values is between a preset lower limit threshold and an upper limit threshold, the difference from the previous value is displayed as normal.

On the other hand, if the difference between the two values is out of a value corresponding to the range between the preset lower limit threshold and the upper limit threshold, the management object has an abnormality and the difference from the previous value is displayed.

As another example, when the comparison result, for example, the difference between the two values is greater than a preset difference value, it is detected that there is something wrong with the management target.

On the other hand, if the difference between the two values is less than the preset difference value, it is detected that the management target operates normally.

Therefore, through this, when an abnormal phenomenon of a management target, for example, a sudden increase in gas usage, a quick end of work, or non-collection of data occurs, an abnormal phenomenon notification is provided.
