Description

IoT-based river disaster monitoring and facility autonomous inspection system using intelligent remote terminal device

The present invention relates to an IoT-based river disaster monitoring and facility autonomous inspection system using an intelligent remote terminal device, and more specifically, an intelligent remote terminal device (RTU) 200 is installed in each river disaster management facility to control water level. Takes autonomous measures, and autonomously checks the operation status of the inspection objects installed in the river disaster management facility, generates autonomous action event information and failure information for each inspection object, and sends it to the central management server 400 through the IoT communication network. By providing, it relates to an IoT-based river disaster monitoring and facility autonomous inspection system using an intelligent remote terminal device that enables effective and efficient river management by preemptive initial response when an event required for river management occurs.

When controlling facilities at the point of occurrence of rain due to environmental changes due to global warming, it shows a large amount of rainfall for a short period of time, which exceeds the equivalent of drainage, so the solution is the existing remote measurement monitoring (TM/TC) system method. It was not found, and it reached the limit of structural response such as pump capacity increase and drainage remodeling.

In the remote management system of the existing disaster management facility in the river, when the inflow level rises when a rainfall occurs and reaches the management level set by the administrator, the system automatically operates the river disaster management facility's water gate or pump in sequence to drain, but the drainage In case of heavy rains in a short period of time exceeding the amount, it was forced to suffer from flooding.

Therefore, it is necessary to reduce the flood damage by installing a step-by-step autonomous adjustment program according to the water level change in the system based on the discharge amount information of the sluice gate or pump and the flow rate information flowing into the inflow tank before reaching the management level in the event of rainfall.

In addition, it is a difficult reality for limited personnel to manage concurrent machine, communication problems, and on-site variable occurrences in multiple facilities in an urgent situation such as localized heavy rain.

In other words, in the case of a monitoring and measurement control system that is remotely managed by manpower, it is impossible to remotely control due to a failure due to an overload of the machine or communication loss. It can't be done, leading to human and property damage.

The method of operating the drainage system in the river was to appoint a local resident as a civilian sluice manager, and operate it by hand (manual or electric) by a private sluice manager.

However, this method had problems such as aging of the floodgate manager, lack of expertise, and unclear liability in the event of damage, and there has been a risk of safety accidents that may occur during the field trip process, especially during nighttime or bad weather.

Therefore, it is necessary to establish a smart river management system using the fourth industrial technology.

With the advent of artificial intelligence and the intelligentization of objects in the era of the 4th Industrial Revolution, things are becoming unmanned autonomy beyond automation as they think and decide for themselves such as data collection, comparison, analysis, judgment, and action.

As in the era of the 3rd Industrial Revolution, a system in which human resources compare, analyze, judge, and act on data is inefficient and culminated.

In other words, it is a passive Internet of Things technology by manpower that measures, collects and transmits the state of a river disaster management facility, and compares, analyzes, and judges it to remotely control it. This has a limit to be judged remotely by manpower when problems such as communication loss, water gates, motors installed in pumps, or measuring instruments occur.

At the Gartner Symposium/IT Expo held in Orlando, Florida, USA on February 18, 2019, Autonomous Things were presented as ``Top 10 Strategic Technology Trends of 2019'' and things that operate autonomously throughout the future industry This trend is going to be rapidly spreading.

Therefore, an intelligent remote terminal device (RTU) equipped with an operating system (OS) is connected to an object to autonomously collect, compare, analyze, judge, and autonomously control data and quickly deliver the results to the manager or related organizations. Conversion is required.

On the other hand, the river disaster management facility in preparation for the heavy rains of the locality must maintain the safety state of the facility so that it can respond to the 24/7 situation.

In the case of regular inspections, weather forecasts, or weather forecasts, emergency checks are conducted to conduct emergency checks. Even if problems are found, there is a time limit to receive and respond to A/S.

In addition, many river disaster management facilities are insured by fire insurance due to a decrease in insulation resistance between the windings of the motor and a failure when the pump starts or leads to a fire.

In addition, measurement equipment such as water level gauges and open water gauges frequently cause malfunctions due to lightning, water gates, or pulses generated when the pump is running, leading to civil complaints and flood damage, so it is urgent to solve these problems.

Due to the increase in the number of disaster management facilities in the river, the existing administrator applies the automation system to the site for remote management in a manual control method of the water gate or pump in the field, but most remote management systems are equipped with their own fault diagnosis function. The technology for determining the presence or absence of a malfunction by grasping the operation status of motors and measurement sensors, which are facilities that have been installed, has not been introduced. Since it is not possible to respond, it is always exposed to disasters.

Although many measurement sensors are installed at the repair facility site for remote river management, in the river disaster management automation system, the fault diagnosis function of its own system is applied, but it is possible to determine the presence or absence of a fault by grasping the operation status of the measurement sensors, which are connected facilities. Despite the fact that the measurement sensor has failed due to the introduction of the technology, it is not always possible to promptly respond to the flood due to malfunctions and incorrect judgments due to improper action.

Therefore, it is very necessary to build a system that monitors the operational state of the measurement sensor for river disaster management in real time, prepares for a failure situation, and can quickly propagate it to the manager.

The Ministry of Land, Infrastructure and Transport strengthened penalties for institutions that performed poor safety inspections of facilities, and as part of the Act on the Amendment of the Special Act on the Safety and Maintenance of Facilities (hereinafter referred to as the Facility Safety Act), promulgated the permission for subcontracting of new technologies, It will be implemented from April. (Excerpt from press release by Ministry of Land, Infrastructure and Transport on January 6, 2020)

The Ministry of Land, Transport and Maritime Affairs expects that the revision of this Enforcement Decree will prevent insolvency inspections, and that the 4th industrial technology will be activated in the field of safety inspections of facilities to enhance and enhance the safety inspections of facilities. He said that he would continue to discover system improvements to enhance the safety of facilities.

Recently, government departments and local governments have established and operated an integrated control room in the government building to manage and manage the facilities scattered in the building.

These on-site facilities are diverse, such as water supply facilities, disaster preparedness facilities, environmental management facilities, and road facilities.

In order to operate facilities in various fields in one integrated control room, personnel in each field must reside and monitor 24 hours a day, 365 days a year, and find and act on the problem.

The HMI program in the integrated management room, which is currently in operation, receives various data and displays them on the operation screen, and the administrator is operating in the form of viewing, comparing, analyzing, judging, and remotely controlling the measurement screen.

Therefore, many operating personnel are deployed in each area within the integrated control room to monitor the facilities 24 hours a day and night.

In the case of local governments, the person in charge of the relevant department performs various tasks. If monitoring is performed in the integrated control room, difficulties arise that cannot see other tasks.

In addition, it takes from minutes to tens of minutes to find the data stored in the database, and frequent data deficits occur due to communication loss.

In addition, the data of the object is collected and transmitted through the Internet of Things, and the subject to perform this is the remote terminal device (RTU), which is not connected to the object and transmits error data. If it does, there is a problem with various complaints and initial responses because proper judgment and action cannot be made.

Therefore, an intelligent remote terminal device (RTU) equipped with an operating system (OS) checks the collected data to detect errors, saves the data itself when communication is lost, and automatically recovers the communication restart data after saving itself. A method that can transmit seamlessly should be applied.

The autonomous operating platform installed in the integrated control room compares, analyzes, and judges the data received from the site with the management manual, informs the relevant managers of the necessary information, separates and stores the information in the database, and responds and measures by notifying the connected remote terminal devices. It should be done.

Systems and systems, systems and administrators, related organizations, and city residents need a disaster management autonomous program using big data.

The detection means 100 is installed for each river disaster management facility 10, and performs a function of transmitting detection information for each sensing factor necessary for water level management to the intelligent remote terminal device (RTU) 200.

The river disaster management facility 10 described in the present invention may be, for example, a dam management facility, a reservoir management facility, a beam management facility, a drainage management facility, a rainwater pumping station management facility, a river gate management facility, a drainage gate management facility. In addition, the detection means 100 is installed in a river disaster management facility to perform the function of real-time sensing the status of various auxiliary facilities to manage the water level.

Specifically, the detection means 100, as shown in Figure 2,

Water level detection means (110) is installed for each water gate that is a water level response means (300) to detect the water level inside the water gate, and transmit the water level detection information to an intelligent remote terminal device (RTU) (200),

It is installed in the water passage to detect the flow rate, and the flow rate sensor 140 for transmitting the flow rate detection information to the intelligent remote terminal device (RTU) (200),

A pressure sensor 150 installed in a water passage to detect water pressure and transmit pressure sensing information to an intelligent remote terminal device (RTU) 200;

At least one current sensing sensor 170 that senses a current value of a motor installed for each water gate 310 which is a water level response means 300 and transmits current sensing information to an intelligent remote terminal device (RTU) 200.

Specifically, the water level detection sensor 110 is installed for each water gate that is a water level response means 300 to detect the water level inside the water gate, and the detected water level detection information to the intelligent remote terminal device (RTU) 200 Will be sent.

The external water level sensor 120 is installed for each water gate, which is a water level countermeasure 300, to sense the external water level outside the water gate and transmit the external water level detection information to the intelligent remote terminal device (RTU) 200.

For example, the information of the inner water level of 2.83M and the outer water level of 2.65M is transmitted to the remote terminal device (RTU) 200.

The opening rate detection sensor 130 is installed for each water gate which is a water level response means 300 to detect the opening rate of the water gate and transmit the opening rate detection information to the intelligent remote terminal device (RTU) 200.

For example, it is installed on the water gate of the dam and provides information of an opening rate of 15%, which is an open state of the water gate, so that the manager can check the current opening rate state in real time.

The flow rate sensor 140 is installed in the water passage to detect the flow rate, and transmits the flow rate detection information to the intelligent remote terminal device (RTU) 200.

For example, it is installed in a water pipe to calculate the water level, structure, and speed to calculate the flow rate, so that the manager can check in real time how much the flow rate is in the water pipe.

The pressure sensor 150 is installed in the water passage to detect the pressure of the water, and transmits the pressure detection information to the intelligent remote terminal device (RTU) (200).

The vibration detection sensor unit 160 detects the vibration value of a motor installed for each water gate 310 which is a water level response means 300, and transmits vibration detection information to an intelligent remote terminal device (RTU) 200.

The current detection sensor unit 170 senses the current value of the motor installed for each water gate 310, which is the water level response means 300, and transmits the current detection information to the intelligent remote terminal device (RTU) 200.

For example, by providing information of a current value of 5 mA of a water gate opening/closing motor configured in the water gate of the dam, the administrator can check the current current state in real time.

It is characterized in that the above-mentioned detection information transmitted by each sensor includes unique identification information and a detection value of the corresponding sensor. The unique identification information of the sensor included in the detection information is used as basic data for confirming the position of the sensor, and the sensor value included in the detection information is used as the basic data for determining whether or not the corresponding sensor has failed.

The camera 101 is installed around the water level response means 300, and transmits the image information of the operation state of the water level response means 300 to the intelligent remote terminal device (RTU) 200.

For example, the water gate of the dam is photographed so that the current status of the water gate can be checked in real time by the administrator.

The intelligent remote terminal device (RTU) 200 is installed in each river disaster management facility 10, and the water level control means 300 is operated by using the sensing information for each sensing factor transmitted by the sensing means 100. After taking autonomous action, it generates autonomous action event information and transmits it to the central management server 400, autonomously checks the operation status of the inspected objects, generates fault information for each inspected object according to the inspection results, and then communicates with the IoT network. Through this, the function provided to the central management server 400 is performed.

In other words, the intelligent remote terminal device (RTU) 200 of the present invention is a core configuration for autonomous inspection and autonomous operation of a river disaster management facility, and in general, an intelligent remote terminal device (RTU) that is various facilities installed in a river disaster management facility. (200) The self and the detection means 100 and the water level response means 300 are checked at any time, and in the event of an accident, initial handling is performed according to the accident handling manual.

In particular, the present invention-based river disaster monitoring and facility autonomous inspection system, which includes an intelligent remote terminal device having an autonomous inspection function, addresses the problem of delayed and false detection of the existing sensor detection, the Internet of Things (IoT), the fourth industrial revolution technology. And by applying intelligent technology, it is possible to implement a highly reliable river disaster monitoring system by autonomously inspecting and operating the sensor's status and data errors to inform the administrator.

In the conventional technology, many measurement sensors are installed at the repair facility site for remote river management, but in the river disaster management automation system, the fault diagnosis function of its own system is applied, but the operation status of the measurement sensors, which are connected facilities, is identified and broken. Despite the fact that the measurement sensor has failed because the technology for determining the presence or absence has not been implemented, it is not possible to promptly respond due to malfunctions and incorrect judgments due to malfunctions and incorrect judgments. That is true.

However, according to the present invention, by quickly operating the water level response means according to the situation, autonomous measures are taken without an administrator's command from the management agency, so that the rapid river disaster response is performed before reaching the management level, and the operation state of the inspection objects By autonomous inspection to exert the effect of preparing for accidents 24 hours a day, 365 days a week through real-time safety inspection or daily safety inspection, it is possible to solve the problems of the prior art described above.

Features of the intelligent remote terminal device 200 will be described in detail with reference to FIGS. 2 to 3.

The intelligent remote terminal device 200, the water level response means autonomous inspection unit 210, detection means autonomous inspection unit 220, RTU autonomous inspection unit 230, central control unit 240, autonomous action unit 250, It will be configured to include the Internet of Things wireless communication unit 260.

In detail, the water level response means autonomous check unit 210 periodically checks automatically with the water level response means 300 in accordance with preset autonomous inspection schedule information in order to autonomously check the operation state of the water level response means 300. When the signal is transmitted, and when the response signal for the autonomous check signal is obtained from the water level response means 300, it is determined as normal, and the unique identification information of the water level response means 300 that has not obtained the response signal is extracted, and the extracted unique identification It generates a failure information for each water level response means including information, and transmits the generated failure information for each water level response means to the central management server 400 through the IoT wireless communication unit 260.

That is, after sending the autonomous check signal to the water level response means (water gate, motor for opening and closing the hydro gate, broadcasting device, drone, etc.) periodically, it is judged as normal when acquiring the response signal to the autonomous check signal. do. However, when the response signal is not obtained, failure information for the corresponding water level response means is generated.

For example, if an autonomous check signal is transmitted to a motor for opening and closing a sluice gate, and a response signal cannot be obtained, the unique identification information of the motor for opening and closing the sluice gate is extracted, and the sluice opening and closing gate including the unique identification information of the motor for opening and closing the sluice gate It is to generate failure information of the motor and transmit it to the central management server 400 through the IoT wireless communication unit 260.

The detection means autonomous inspection unit 220 receives the detection value information from the detection means 100 periodically in order to autonomously check the operation state of the detection means 100, and the detection means ( 100) to determine whether or not the failure, and extracts the unique identification information of the detection means 100 determined to be a failure, and generates failure information for each detection means including the extracted unique identification information, and then generates the failure information for each detection means To the central management server 400 through the IoT wireless communication unit 260.

In order to perform the above functions, the sensing means autonomous inspection unit 220,

A sensing value receiving module 221 for receiving an analog current sensing value or an analog voltage sensing value from the sensing means 100,

Digital conversion module 222 for converting the received analog detection value to a digital value,

A failure determination module 223 for determining whether the detection means 100 has failed using the change characteristic of the converted digital value;

After extracting the unique identification information of the detection means 100 determined as a failure, and generating the failure information for each detection means including the extracted unique identification information, the failure information for each detection means is generated by the IoT wireless communication unit 260. It includes a detection means failure information generation module 224 to be transmitted to the central management server 400 through.

Specifically, the detection value receiving module 221 receives an analog current detection value or an analog voltage detection value from the detection means 100, and provides the received analog detection value to the digital conversion module 222 to detect the received analog. The value is converted to a digital value.

At this time, the normal range of the analog detection value received by the detection value receiving module 221 is current (4mA to 24mA) or voltage (1v to 5v), and the normal range of digital values converted by the digital conversion module 222 Characterized in that (13107 ~ 65535).

For example, the sensing means for providing an analog detection value is different in kind, such as a water level sensor, an external water level sensor, an opening degree sensor, a flow rate sensor, a pressure sensor, a vibration sensor, a current sensor, etc. In this case, the analog current sensing values provided by the sensing means are in the range (4mA to 24mA), and the analog voltage sensing values are in the range (1v to 5v).

In addition, the digital value obtained by converting the analog detection value into a digital value is in the range (13107 to 65535).

That is, the digital conversion module 222 converts the analog current detection value 4mA or analog voltage detection value 1v to a digital value of 13107, and converts the analog current detection value 20mA or analog voltage detection value 5v to a digital value of 65535.

Of course, the analog current detection value between (4mA ~ 24mA) or the analog voltage detection value between (1v ~ 5v) is converted to a digital value between (13107 ~ 65535).

The fault determination module 223 does not have a converted digital value, the converted digital value is fixed, or the converted digital value is fluctuating outside the normal range (13107 to 65535), or the converted digital value If only two digital values are fluctuating, it is judged as a failure.

For example, if the converted digital value does not exist, it means that the analog sense value is not sensed, which can be judged as a failure.

And, if the digital value is in the normal range or out of the normal range, it is judged as a failure if it is a constant fixed value without moving.

For example, the digital value is normal only when there is a slight difference in every moment, but it is fluctuating, and the digital value that does not change is judged to be abnormal.

Then, if the digital value fluctuates outside the normal range (13107 to 65535), it is determined as a failure.

For example, the normal digital value should be changed within the range of (13107 ~ 65535), and if it is within the range of the digital value (66545 ~ 67777) that is outside the normal range, it is judged as a failure.

In addition, when the converted digital value fluctuates only in two digital values (called a hunting phenomenon), it is also judged as a failure.

For example, if the converted digital value of the vibration sensor switches between two values of 14100 and 59000, it detects 1 m/s ^{2 and} then detects 9 m/s ² , and then detects 1 m/s ² again. Then, it detects 9 m/s ^2, and it is common sense that such a detection is not possible, so it is judged as a failure.

The fluctuation of the digital value described above will be described in detail.

The sensing means 100 is different in kind, but if it is normal, the analog current detection value must fluctuate slightly every moment within the range of 4mA to 24mA, so the converted digital value must fluctuate slightly every moment within the range (13107 to 65535).

For example, when a vibration detection sensor capable of detecting vibrations from 1 m/s ² to 10 m/s ² detects 1 m/s ² vibrations, the digital value fluctuates frequently from the lowest digital value of 13107 (13107, 13110, 13108, 13109...) is normal, and when 10 m/s ² vibration is detected, the digital value should fluctuate (65535, 65530, 65527, 65529...) from around 65535, the highest digital value.

That is, if the sensing means 100 having different detection targets and types are normal, all of the digital values obtained by converting the detection values to digital are normally changed slightly every moment within the range (13107 to 65535).

The RTU autonomous inspection unit 230 periodically transmits an RTU autonomous inspection signal to the central control unit 240 in accordance with preset RTU autonomous inspection schedule information to autonomously check the operation state of the intelligent remote terminal device itself, and the RTU autonomy If the response signal of the central control unit 240 is obtained for the check signal, it is determined as normal. If the response signal is not obtained, the unique identification information of the intelligent remote terminal device is extracted, and RTU failure information including the extracted unique identification information is generated. Then, the generated RTU failure information is transmitted to the central management server 400 through the IoT wireless communication unit 260.

For example, an RTU autonomous check signal called'AUTO_REQUEST#ID:1-RTU#POWER#2020-03-03-09:01' is generated and transmitted to the central control unit 240, and the response signal is'ID: If the 1-RTU#POWER#OK#2020-03-03-09:01' signal is obtained from the central control unit, it is judged to be normal, but if the response signal for the autonomous check signal is not obtained, its own identification information Generates RTU failure information of'ID:1-RTU#POWER-ERROR#2020-03-03-09:01', which includes'ID:1-RTU', and the generated RTU failure information is generated by the Internet of Things Wireless Communication Department. It is to be transmitted to the central management server 400 through (260).

The central control unit 240 controls the operation of each component constituting the intelligent remote terminal device, and upon receiving the RTU autonomous check signal, checks the operation state of each component constituting the intelligent remote terminal device, and the inspection result If all the components are normal, the RTU autonomous checker 230 provides a response signal, and if any of the components is abnormal, the RTU autonomous checker 230 provides a response signal.

For example, when receiving the RTU autonomous check signal'AUTO_REQUEST#ID:1-RTU#POWER#2020-03-03-09:01' to check the operation state of the power supply from the RTU autonomous check unit 230 , Check the operation status of the power supply, which is a component constituting the intelligent remote terminal device, and provide a response signal for the RTU autonomous check signal to the RTU autonomous check unit 230 if there is no abnormality as a result of the inspection, and if there is an abnormality, respond to It will not be provided to the RTU autonomous inspection unit 230.

In the above example, the operation of the power supply, which is a component constituting the intelligent remote terminal device, was exemplified, but the operation check is performed on all components constituting the intelligent remote terminal device, and a response is made if there is more than one. The signal is not provided to the RTU autonomous checker 230.

In particular, if the central control unit 240 does not provide a response signal to the RTU autonomous check unit 230 (as a result of operation check for all components constituting the intelligent remote terminal device, if there is more than one), it is abnormal. Provides information about the components.

In this case, the RTU autonomous checking unit 230 is characterized in that when the information on the abnormal component is provided instead of the response signal from the central control unit 240, the information on the abnormal component is included in the RTU failure information.

In the present invention, it is possible to accurately analyze even the failure of the intelligent remote terminal device 200 by configuring the RTU autonomous inspection unit 230 and the central control unit 240 as described above.

That is, the RTU autonomous checking unit 230 generates failure information when the response signal is not obtained from the central control unit 240, and generates failure information even when obtaining information about an abnormal component instead of the response signal, but generates failure information. To include information about non-normal components.

The autonomous action unit 250 operates the water level countermeasures 300 by using the sensing information for each sensing factor transmitted by the sensing means 100, takes autonomous measures for water level adjustment, and uniquely identifies the intelligent remote terminal device. The autonomous action event information including information, autonomous action content information, and video information transmitted by the camera 101 is generated and transmitted to the central management server 400.

Through the autonomous action event information, it is possible to check the river disaster management facility, autonomous action, and the current status of autonomous action.

Specifically, the autonomous action unit 250,

A management information storage module 251 for storing management information including hourly leakage capacity information and management level information for each water gate of the water gates 310 which are water level countermeasures 300;

Management that determines whether the water level has reached the management level by using the water level information obtained from the internal water level sensor 110 and the external water level sensor 120, which are the detection means 100, and the management water level information stored in the management information storage module. Water level determination module 252,

As a result of the determination of the management water level determination module 252, when the inner water level reaches the control water level and the inner water level is higher than the outer water level, the speed and the management information of the water level rise by the water level information provided by the water level detection sensor 110 A water level correspondence means determination module 253 for determining water level 310, which is a water level correspondence means 300 to be operated by using the hourly leakage capacity information for each water gate stored in the storage module,

When the water gates 310 to be operated by the water level response means determination module 253 are determined, an action signal is transmitted to the determined water gates, autonomous measures are taken, and autonomous action event information is generated and transmitted to the central management server 400 The water level response means autonomous measure module 254 is included.

Specifically, the management information storage module 251 stores management information including hourly leakage capacity information and management level information for each water gate of the water gates 310 that are water level countermeasures 300.

For example, the management information may include the outflow capacity of the water gate per hour: 100 m ³ /min, the management water level: 20 m, and the like.

The management water level determination module 252 uses the water level information obtained from the internal water level sensor 110 and the external water level sensor 120, which are detection means 100, and the management water level information stored in the management information storage module. Will determine if the management level has been reached.

The stored management water level is a value that can be regularly set and changed by an administrator according to the site situation.

For example, when the management water level is 20m, when the water level value transmitted from the water level sensor does not exceed 20m, it is normal.

At this time, as a result of the judgment of the management water level determination module, when the inner water level reaches the management water level (for example, when it reaches 20 m), and the inner water level is higher than the outer water level, the water gate is opened.

The water level response means determination module 253 is determined by the management level determination module 252, and when the internal water level reaches the management water level and the internal water level is higher than the external water level, the water level detection sensor 110 provides the internal water level. The function of determining the water level 310 which is the water level response means 300 to operate by using the information on the rate of rise of the water level by the information and the hourly outflow capacity information for each water gate stored in the management information storage module.

For example, the inflow of water per hour according to the rate of rise of the water level by the water level information is calculated according to the following formula.

<Calculation formula>

Domestic water inflow per hour according to the rate of rise in the domestic water level = Domestic water inflow per unit water level × Water level increase per unit time

For example, if the water level rise per unit time (min) is 2 cm and the inflow of water per unit water level is 300 m ³ /cm, the inflow of water per hour according to the rate of water rise is calculated as 600 m ³ /min.

The number of gates to be opened is determined by dividing the inflow of water per hour by the calculated rate of rising water level by the flow rate per hour.

For example, the hourly flow rate of the domestic water level rising speed is 600m ³ / min and determining the number, contact number is water gate 1 hour to discharge opening is 100m ³ / min 6 dogs.

When the water level response means autonomous action module 254 determines the water gates 310 to be operated by the water level response means determination module 253, it sends an operation signal to the determined water gates to take autonomous action and then autonomous action event information Creates and transmits to the central management server 400.

That is, when the number of gates to be opened is determined, an open signal is transmitted to the switch of the gate to be opened to take autonomous action.

And, after taking autonomous action, autonomous action event information is generated and transmitted to the central management server 400, so that the manager of the management institution can confirm this and take follow-up actions.

The autonomous action event information includes unique identification information of the intelligent remote terminal device, autonomous action content information (control level reached), and on-site video information.

For example, #ID:1-RTU#ID:1-Water level SENSOR#Management level reached#6ea_water gate_auto_event#Broadcasting_auto_event#2020-03-03-09:01' is generated and generated by autonomous action event information. Will be sent to

On the other hand, when the water level response means autonomous action module 254 takes an autonomous action to open all water gates, and the rate of rise in the water level exceeds the allowable value by the water level detection information provided by the water level detection sensor 110. , Provides flight command information to the drone 700 and generates river flooding event information including field image information provided by the drone and its own identification information and provides it to the central management server 400. Details will be described in the autonomous action event processing unit 410, which will be described later.

The IoT wireless communication unit 260 is generated by the failure information and the autonomous action unit 250 generated by the water level countermeasures autonomous checker 210, the detection means autonomous checker 220, and the RTU autonomous checker 230. The autonomous action event information is transmitted to the central management server 400 through the IoT network.

The Internet of Things (IoT) network is an advantageous communication network for transmitting small measurement and monitoring information with a small data capacity. Since the communication cost is only about 1,200 won/month, the communication cost is much lower than that of a general communication network, thereby providing the advantage of service.

Currently, manufacturing and monitoring devices are inexpensive to manufacture, but monthly maintenance costs are incurred in the monitoring service field, which requires the management of numerous branches because monthly communication costs are required. It is hesitant to introduce the system. However, in the present invention, since the Internet of Things method is used, communication costs can be significantly reduced, and thus it is expected to be widely used in the field of monitoring services.

On the other hand, the intelligent remote terminal device (RTU) 200 of the present invention may further include an automatic communication loss data recovery unit 270, the automatic communication loss data recovery unit 270, as shown in FIG.

It sends a response request signal to the IP address of the central management server 400 and checks whether it receives an answer signal, but if it does not receive an answer signal, it determines that it is a communication error and counts a predetermined number of counts. If not, the connection communication monitoring module 271 for sending a reset command signal to the communication power reset command module:

Communication power reset command module 272 for resetting the power of the IoT wireless communication unit 260:

Upon reset, the response signal check module (273) after resetting is sent to the central management server's IP address again to check if the response signal is received.

Even if the answer signal is checked again by the answer signal check module after the reset, if the answer signal is not received, it is determined to be a communication failure and responds to the continuous operation command information to continuously perform autonomous check according to the set scenario after the point of communication failure. Sudan autonomous inspection unit 210, detection means autonomous inspection unit 220, RTU autonomous inspection unit 230 for continuous operation command signal transmission module for sending out:

The continuous operation result storage processing module 275 for storing and processing the autonomous check result information processed according to the continuous operation command information into the continuous operation result storage module:

The continuous operation result storage module 276 that stores the autonomous inspection result information provided by the continuous operation result storage processing module:

Communication recovery check module (277) that periodically checks whether an answer signal is received by sending an answer request signal to the IP address of the central management server:

When receiving an answer signal from the central management server, it characterized in that it comprises a continuous operation result information transmission module (278): to transmit the autonomous check result information stored in the continuous operation result storage module to the central management server.

Specifically, the access communication monitoring module 271 checks whether an answer signal is received by sending an answer request signal to the IP address of the central management server 400. If the count is performed as many as the number of counts and the answer signal is not continuously received afterwards, a function for transmitting a reset command signal to the communication power reset command module is performed.

For example, according to the set time, the current IP address is sent to the DDNS server located in the central management room, and the DDNS server determines the normal communication state when an ACK signal is sent to the access communication monitoring module.

However, when there is a communication failure, the access communication monitoring module cannot receive an ACK signal even if the IP address is sent to the DDNS server.

If it is judged that the communication is in an abnormal state, for example, if it is set for a predetermined number of counts for 5 seconds, if an answer signal is not received within 5 seconds, a reset command signal is sent to the communication power reset command module.

At this time, the communication power reset command module 272 resets the power of the IoT wireless communication unit 260.

Thereafter, after reset, the response signal check module 273 checks whether the response signal is received by re-sending the response request signal to the IP address of the central management server upon reset.

This is to increase the accuracy of communication disconnection determination through duplication check, and since a communication disconnection may occur due to an error in the communication unit, an answer request signal is sent again after reset.

Further, the continuous operation command signal transmission module 274, if the answer signal is not received even if the answer signal is checked again by the answer signal check module after the reset, it is determined as a communication failure and performs an autonomous check according to the set scenario after the point of communication failure. The continuous operation command information to be continuously performed is transmitted to the water level corresponding means autonomous inspection unit 210, the detection means autonomous inspection unit 220, and the RTU autonomous inspection unit 230.

In this case, the autonomous check of the water level corresponding means autonomous checker 210, the sensing means autonomous checker 220, and the RTU autonomous checker 230 is performed according to the predetermined scenario regardless of the communication disconnection state.

In the related art, in addition to the flow of notifying the administrator when a communication loss occurs, the system does not perform a subsequent operation, thereby causing secondary damage.

However, in the case of the present invention, it is possible to prevent the secondary damage from occurring in advance, thereby preventing serious damage to the system.

On the other hand, in the present invention, the normal operating state and the operating state from the time of communication interruption to the resumption time are separately stored and the operation state information from the time of communication interruption to resumption time is defined as continuous operation result information.

The continuous operation result storage processing module 275 stores the autonomous check result information processed according to the continuous operation command information as a continuous operation result storage module.

The continuous operation result storage module 276 stores the autonomous check result information provided by the continuous operation result storage processing module 275. Normally, operation result information is not stored, and communication is restarted from the time of communication interruption. The storage process is dualized so that only the result of the operation until is stored.

Then, the communication recovery check module 277 periodically sends an answer request signal to the IP address of the central management server to check whether the answer signal is received.

In addition, when receiving a response signal from the central management server, the continuous operation result information transmission module 278 transmits the autonomous inspection result information stored in the continuous operation result storage module to the central management server.

Therefore, it is possible to prevent information omission by automatically providing auto-checked information during communication inactivity when communication is restarted.
