1 is a configuration diagram of a control system through integrated environmental 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 data to determine the situation of each site.

The on-site controller 100 can detachably use the IP camera module 300 and the IoT gateway module 400.

The control server 200, the data management unit 210 for storing the received data in the database 220, and receives and analyzes the data received from the data management unit 210, analysis that can grasp the situation of each site The data analysis unit 230 for generating data, the situation determination unit 250 for determining the situation of each site using the analysis data, and the data management unit 210 while monitoring the data and the situation determination unit ( 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 field controller 100 according to the determination result of the situation determination unit 250.

Includes.

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

Hereinafter, the configuration and operation of the integrated environmental 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 drawing, the site 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 multiple field controllers 100.

The on-site controller 100 has a plurality of module coupling parts, and it is assumed that function modules conforming to the method of the on-site controller 100 can be detached.

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

1 illustrates a state in which one IP camera module 300 and one IoT gateway module 400 are combined 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 can be used in combination at the same time, and only the IP camera module 300 or the IOT gateway module 400 can be selectively used.

This has the effect of making it easy to 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 obtained 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, recently, it can be a variety of devices, such as wearable devices, smartphones, and cameras with separately manufactured communication functions, to prevent the occurrence of safety accidents by workers, and to immediately check whether a safety accident has occurred. The biosignal information of the individual worker or the surrounding environment information of the 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 site, and at this time, the collected data of the field controller 100 must be controlled to operate smoothly, and the field controller 100 It can prevent a decrease in reliability.

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

Next, 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 the IP camera module 300 and the IoT are performed by performing control set according to the load diagram. The gateway module 400 is controlled.

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

Referring to FIG. 2, the load control unit 110 obtains a ratio of the load information collection unit 111 for collecting load information and the data received through the IoT gateway module 400 with respect to the total load, and the load diagram It may be configured to include a module controller 113 for controlling the IP camera module 300 and the IoT gateway module 400 in accordance with the load analysis unit 112 to determine, and the load diagram.

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

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

The calculation of the load diagram is a value that increases in a predetermined unit 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 a reference value.

For example, if the reference value is 20%, the predetermined unit is 5%, and the load increase amount is 1, the IoT gateway module 400 or IP camera for the total amount of data calculated by the current load analysis unit 112 When the data ratio of the module 300 is 31%, the load degree is 3.

In addition, when the currently detected ratio is 36, the load degree is increased by 1 and becomes 4.

As described above, the load analysis unit 112 calculates a load diagram, and the module control unit 113 controls the IP camera module 300 and the IoT gateway module 400 according to the load diagram.

For example, the module control unit 113 may have a plurality of reference values for the load diagram, and the IP camera module 300 increases as the load increases by controlling the IP camera module 300 according to the range of the load diagram. ) To reduce the resolution of the video. In addition, by controlling the number of frames taken per second, the data amount of the IP camera module 300 can be reduced to lower the total load.

This assumes when the load of the IP camera module 300 increases, and when the load of the IoT gateway module 400 increases, it performs appropriate control to reduce data received through the IoT gateway module 400. Alternatively, regardless of the load diagram, the total amount of data can be reduced by controlling the resolution or the number of frames of the image captured through the IP camera module 300.

As described above, the present invention can control data acquired according to the load of data collected in the field controller 100.

The calculation of the load diagram 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 be substantially a buffer memory, and an internal buffer may be used to control the speed of data transmitted through the wired communication module 150.

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

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

The data of the field controller 100 in which the load is adjusted as described above is transmitted to the control server 200, and the control server 200 analyzes the received data to analyze the situation in the field and take measures to respond according to the analysis result. To take.

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

The data analysis unit 230 analyzes data of the received 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 result 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 for analyzing the situation using the data mapped from the, a generation module 236 for generating analysis data according to the analysis results of the situation analysis module 235, and analysis data for storing the analysis data 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 gas concentration with the measured gas concentration.

In addition, if the data detected by the IoT device 410 is an acceleration sensor, and detects and transmits an operator'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 captured by the IP camera module 300. The processing at this time means processing in a state in which it is easy to acquire specific information from an image.

Next, 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.

Next, the mapping module 233 maps analysis data of the data analysis module 231 and analysis results of the image analysis module 234 according to time and location. The occurrence of a specific accident can be clearly determined based on the mapping result.

Next, the situation analysis module 235 checks the mapping result to track whether there is an abnormality pattern at a specific time and location, and analyzes the situation.

Then, according to the analysis result of the situation analysis module 235, the generation module 236 generates analysis data. The analysis data shall consist 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 according to reception of analysis data indicating whether an accident is an accident to recognize the occurrence of an emergency. . 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 upon 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 the above process, the present invention can accurately determine whether an accident has occurred by processing data detected by the field controller 100, and provide a determination result to the field controller 100 so that the situation can be corrected. Can.

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

Referring to FIG. 4, as in step S41, the load information collecting unit 111 of the load control unit 110 checks the received data to see whether the current IP camera module 300 and the IoT gateway module 400 are all connected. To confirm.

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

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

In step S43, 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 a reference amount as a result of the determination in step S42, it is determined that the load is increased and performs control to reduce it.

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 data received as described above.

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

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

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

At this time, the data reduction control 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 having low importance is released and the data is removed. You can use the blocking method.

As described above, the present invention processes the collected data when the load is large in consideration of the load of the transmission data, and prevents a decrease in transmission speed or a case of transmission failure, thereby preventing a decrease in reliability of products felt by consumers. Can.
