1 is a block diagram of a control system through an integrated environment monitoring according to a preferred embodiment of the present invention.

Referring to FIG. 1, the present invention includes a field controller 100 and a control server 200 that collects and manages data of the field controller 100 and analyzes the data to determine the situation of each site.

The field controller 100 can use the IP camera module 300 and the IoT gateway module 400 in a detachable manner.

The control server 200 includes a data management unit 210 that stores the received data in the database 220, and an analysis capable of identifying the situation of each site by receiving and analyzing the data received from the data management unit 210 A data analysis unit 230 for generating data, a situation determination unit 250 for determining the situation of each site using the analysis data, and a situation determination unit while monitoring the data of the data management unit 210 It includes a monitoring unit 240 for displaying the determination result of 250, and an emergency notification unit 260 for transmitting an emergency notification to the on-site controller 100 according to the determination result of the situation determination unit 250.

The field controller 100 is installed in an industrial site to be monitored, and changes and controls the data collection format according to the load of data received from the detachable IP camera module 300 and the IoT gateway module 400. A load control unit 110, a data packet control unit 120 that receives the load analysis data analyzed by the load control unit 110 and adjusts the total packet data of the transmission data according to the load, and the data packet control unit 120 The main control unit 140 that transmits the data of the data to the control server 200 through the wired communication module 150 or controls the wireless communication module 130, and the environment monitoring sensor unit 160 that detects dangerous environment information. Include.

The IoT gateway module 400 receives signals sensed by a plurality of IoT devices 410 and provides them to the field controller 100.

Hereinafter, the configuration and operation of the integrated environment monitoring system according to a preferred embodiment of the present invention configured as described above will be described in more detail.

First, although not shown in the drawings, the field controller 100 may be installed in a number of different sites. That is, it is assumed that one control server 200 receives and manages data of a plurality of field controllers 100.

It is assumed that the on-site controller 100 has a plurality of module coupling units, and functional modules conforming to the method of the on-site controller 100 can be attached and detached.

For example, it is assumed that the manufacturer of the field controller 100 can manufacture and sell the IP camera module 300 and the IoT gateway module 400 that can be selectively combined with the field controller 100 to be used.

1 shows a state in which one IP camera module 300 and one IoT gateway module 400 are combined in order to describe the characteristic configuration of the present invention, but a plurality of IP camera modules 300 and a plurality of IoT The gateway module 400 may be combined and used at the same time, and only the IP camera module 300 or the IOT gateway module 400 may be selectively used.

This has the effect of making it possible to easily implement a monitoring control system that meets the requirements of the site where the field controller 100 is installed.

The IP camera module 300 acquires a surveillance image at an installation location and provides the acquired surveillance image to the field controller 100.

In addition, the IoT gateway module 400 may serve to collect data of various IoT devices 410 and provide it to the field controller 100.

At this time, the IoT devices 410 may be facilities installed on the site, and in this case, operation information and sensing information of the facilities may be collected. In addition, in recent years, it may be a variety of devices such as a wearable device worn by an individual worker, a smartphone, and a camera having a separately manufactured communication function to prevent the occurrence of personal safety accidents and to immediately check whether a safety accident has occurred. Bio-signal information of an individual worker or information of an environment surrounding an individual worker may be collected through the IoT gateway module 400 and provided to the field controller 100.

That is, the data collected using one field controller 100 may be very variable depending on the situation of the field, and at this time, the field controller 100 must control the collected data of the field controller 100 to ensure smooth operation. It can prevent the deterioration of the reliability of

The load control unit 110 checks the amount of total data received through the IoT gateway module 400 from the data of the IP camera module 300 and the data transmitted through the IoT gateway module 400 The number of IoT devices (terminals) connected to the gateway module 400 is checked, and a ratio of the data of the IoT gateway module 400 is calculated from the total data.

Then, when the data ratio of the IoT gateway module 400 to the total amount of data is greater than or equal to the reference value, a load diagram is generated according to the degree, and then the IP camera module 300 and the IoT Controls the gateway module 400.

2 is a block diagram of the load control unit 110.

Referring to FIG. 2, the load control unit 110 obtains a load information collection unit 111 that collects load information, and obtains a ratio of data received through the IoT gateway module 400 to the total load, and calculates a load diagram. It may be configured to include a load amount analysis unit 112 to determine, and a module control unit 113 that controls the IP camera module 300 and the IoT gateway module 400 according to the load.

The load information collection unit 111 receives data from the IP camera module 300 and the IoT gateway module 400, determines the type of the module, and checks the information of the data.

Then, the load analysis unit 112 obtains a ratio of the data of the IoT gateway module 400 or the data of the IP camera module 300 to the total data checked by the load information collection unit 111. In addition, the load analysis unit 112 calculates a load degree according to the calculated ratio.

In order to calculate the load, the concept of a reference value and an increase value is introduced. When the ratio of the data of the IoT gateway module 400 or the IP camera module 300 to the total amount of data is greater than or equal to the reference value, the result of dividing by the increase value is a value that increases by the amount of increase in the load.

For example, if the reference value is 20%, the increase value is 5%, and the load increase amount is 1, the IoT gateway module 400 or IP camera module for the total amount of data calculated by the current load analysis unit 112 When the data ratio of (300) is 31%, the difference from the reference value is 11%, and the value obtained by dividing 11% by the increase value 5% is 2.2. At this time, since the amount of increase in the load is 1, the load is also 3.

In addition, when the currently detected ratio is 36%, the difference from the reference value is 16%, and the value divided by the increase value 5% is 3.2. The load degree at this time is 4.

In this way, the load analysis unit 112 calculates a load degree, and the module control unit 113 controls the IP camera module 300 and the IoT gateway module 400 according to the load degree.

For example, the module control unit 113 may have a plurality of reference values for the load degree, and the IP camera module 300 controls the IP camera module 300 according to the range of the load degree to increase the load degree. ) To reduce the resolution of the video being shot. In addition, it is possible to reduce the total load by reducing the amount of data in the IP camera module 300 by adjusting the number of frames photographed per second.

This is assuming that the load of the IP camera module 300 increases, and when the load of the IoT gateway module 400 increases, appropriate control to reduce data received through the IoT gateway module 400 is performed. Alternatively, the total amount of data may be reduced by controlling the resolution or the number of frames of an image captured through the IP camera module 300 regardless of the load level.

In this way, the present invention can adjust the acquired data according to the load of the data collected in the field controller 100.

The calculation of the load degree is selectively used only when the total amount of data received from the IP camera module 300 and the IoT gateway module 400 exceeds a reference amount.

The data packet control unit 120 may substantially be a buffer memory, and may adjust the speed of data transmitted through the wired communication module 150 using an internal buffer.

For example, when the load is high, it is provided to the main control unit 140 according to the criterion to adjust the transmission speed of the data transmitted through the wired communication module 150 so that the load of the transmitted data can be directly adjusted. .

The environment monitoring sensor unit 160 includes an earthquake sensor, a gas sensor, and the like, and detects a dangerous environment. The data detected by the environment monitoring sensor unit 160 is directly provided to the main control unit 140 so as not to be affected by the data control according to the load described above.

In this way, the data of the field controller 100 whose load is adjusted is transmitted to the control server 200, and the control server 200 analyzes the received data to analyze the situation of the field, and take measures to respond according to the analysis result. Take it.

Specifically, the data management unit 210 stores the received data in the database 220 and provides the data to the data analysis unit 230 and the monitoring unit 240.

The data analysis unit 230 analyzes the received data of the field controller 100 to generate analysis data.

3 is a block diagram of the data analysis unit 230.

The data analysis unit 230 includes a data analysis module 231 for analyzing data of the IoT device 410, an image data processing module 232 for processing data of the IP camera module 300, and the image data processing. An image analysis module 234 that analyzes the processing results of the module 232, a mapping module 233 that maps the analysis results of the data analysis module 231 and the image analysis module 234, and a mapping module 233 A situation analysis module 235 that analyzes a situation using data mapped in, a generation module 236 that generates analysis data according to the analysis result of the situation analysis module 235, and analysis data that stores the analysis data It includes a database 237.

The data analysis module 231 of the data analysis unit 230 analyzes various sensing data detected by the IoT device 410.

For example, when the data detected by the IoT device 410 is a gas concentration, the data analysis unit 230 may analyze the risk by comparing the reference value of the corresponding gas concentration with the measured gas concentration.

In addition, if the data detected by the IoT device 410 is an acceleration sensor that detects and transmits the worker's acceleration, the acceleration direction and speed are checked to analyze whether an accident such as a fall occurs.

At the same time, the image data processing module 232 processes image data photographed by the IP camera module 300. Processing at this time means processing in a state in which it is easy to acquire specific information from the image.

Then, the image analysis module 234 extracts and recognizes object tracking, fire detection, and facial recognition information from the image processed by the image data processing module 232.

Then, the mapping module 233 maps the analysis data of the data analysis module 231 and the analysis result of the image analysis module 234 according to time and location. The occurrence of a specific accident can be clearly judged by this mapping result.

Then, the situation analysis module 235 checks the mapping result, tracks whether there is an abnormal situation pattern at a specific time and location, and analyzes the situation.

Then, the generation module 236 generates analysis data according to the analysis result of the situation analysis module 235. The analysis data consists of location information, time information, accident status, and accident type.

The analysis data is provided to the situation determination unit 250, and the situation determination unit 250 controls the emergency notification unit 260 to recognize the occurrence of an emergency situation in response to reception of analysis data indicating whether an accident is an accident. . The emergency notification unit 260 may provide emergency notification data to the on-site controller 100, and the on-site controller 100 may generate an alarm according to reception of the emergency notification data.

In addition, the determination result of the situation determination unit 250 is assumed to be displayed on the monitoring unit 240.

Through this process, the present invention can accurately determine whether an accident has occurred by processing the data detected by the field controller 100, and provide the result of the determination to the field controller 100 so that the situation can be corrected. I can.

4 is a flowchart illustrating a data control method of the field controller 100.

4, as in step S41, the load information collection unit 111 of the load control unit 110 checks the received data to see if both the IP camera module 300 and the IoT gateway module 400 are currently connected. Confirm.

Then, as in step S42, if both the IP camera module 300 and the IoT gateway module 400 are connected, whether the total amount of data received from the IP camera module 300 and the IoT gateway module 400 is equal to or greater than the set reference amount. Confirm.

As a result of the determination in step S42, if the total amount of received data is less than the reference amount, it is determined that the data load is low, and the subsequent process is not performed.

In step S43, as a result of the determination in step S42, if the total amount of data received from the IP camera module 300 and the IoT gateway module 400 is greater than or equal to the reference amount, it is determined that the load has increased and control to reduce it is performed.

As described above, the load analysis unit 112 calculates a data ratio representing the ratio of the IP camera module 300 and the IoT gateway module 400 to the total amount of received data.

Then, in step S44, the load amount analysis unit 112 calculates the data ratio as a load degree according to a reference value, an increase unit, and an increase value.

The reason for calculating the load degree is that the data ratio has a wide range and is difficult to use directly for control.

Then, in step S45, the module control unit 113 performs data reduction control determined according to the calculated load level.

The data reduction control at this time may be a reduction in the resolution of the IP camera module 300 or the number of frames taken per second, as described above, and in the case of the IoT gateway module 400, the connection of the IoT device of low importance is disconnected to save data. You can use a blocking method.

In this way, the present invention considers the load of transmission data and processes the collected data when the load is large to prevent a decrease in transmission speed or transmission failure, thereby preventing a decrease in the reliability of the product felt by consumers. I can.
