Description

IoT-based embedded monitoring system {IoT based embedded monitoring system}

The present invention relates to an IoT-based embedded type monitoring system, and more specifically, the data of the instrument from various instruments such as water level, water quality, salinity, and air quality at various sites through DI, PI, AI, LAN, and serial communication methods. Collect, transmit data to a cloud server at a specified time or in real time, accumulate data, and display data on separate mobile and PC, allowing users to remotely monitor field data quickly and conveniently anytime, anywhere. It relates to an IoT-based embedded monitoring system that enables remote control of various machines such as pumps.

In general, the Internet of Things (IoT for abbreviation) means a technology that connects to the Internet by embedding sensors and communication functions in various objects.

Here, objects are various embedded systems such as home appliances, mobile equipment, wearable computers, and various sensors.

Things connected to the Internet of Things must be connected to the Internet with the only IP that can distinguish them, and sensors can be built in to acquire data from external environments.

Since all things can be targeted for hacking, the development of the Internet of Things and the development of security are bound to go together.

According to a survey by the information technology research and advisory company Gartner among the surveys on the Internet of Things, the number of objects using IoT technology was estimated to be 900 million by 2009, but this number will reach 26 billion by 2020.

When many objects are connected in this way, a large amount of data is collected through the Internet, and the collected data becomes vast enough to be difficult to analyze using existing technologies.

This is called big data.

Therefore, it is said that the necessity of technology to develop efficient algorithms for analyzing big data is emerging along with the emergence of the Internet of Things.

And, according to a survey by foreign Cisco systems, the Internet of Things is expected to generate $ 14.4 trillion in economic value for 10 years from 2013 to 2022.

The Internet of Things is an evolutionary step compared to the existing Internet or mobile Internet based on wired communication, and devices connected to the Internet take care of each other without human intervention and process information.

It is similar to the existing ubiquitous or M2M (Machine to Machine) in that things communicate with each other without relying on humans, but it extends the concept of M2M, which aims primarily at communication between communication equipment and people, to the Internet. Therefore, it can be said that it has evolved into the concept of interacting with all information in the real world and virtual world as well as things.

As such, the Internet of Things can be briefly expressed as Internet of Things (IoE)> Internet of Things (IoT)> Internet of Things (M2M), where the Internet of Things is a method created by a specific company, and the Internet of Things comes into the realm of the Internet It is a way, and the thing communication means the way that it cannot enter the realm of the Internet.

The technical settings for using the Internet of Things can be largely divided into identification of objects, establishment of a network capable of communication, imparting sensation to objects, and controllability.

And each entity used in the Internet of Things needs an identity that allows other entities to identify themselves.

Although the technology for identifying the identity of an object located at a short distance is RFID technology, in order to confirm the identity of an individual object on a wider range of networks, an IP address must be assigned to the individual object.

As a result, demand for IP addresses has increased, and there has been a limitation that the existing 32-bit IPv4 system has difficulties in allocating addresses of increasing objects.

As a result, the necessity of the 128-bit IPv6 system is emerging.

In addition, objects for network construction must be able to create new information by exchanging and collecting information collected by themselves with other objects as needed.

MQTT to replace HTTP to establish a consistent way of communicating between things

A protocol has been proposed and MQTT is used as the standard protocol for the Internet of Things in the Advanced Open Standards for the Information Society (OASIS).

And, in terms of the industrial sector, as an example, the process is analyzed and facilities are monitored to improve work efficiency and safety.

It improves productivity and secures safety distribution system by integrating Internet of Things technology into production, processing, and distribution.

The Internet of Things is put into nearby living products to produce high value-added service products.

Also, in the public sector, for example, CCTV and elderly Internet of Things (IoT) information such as GPS is used to prevent disasters or disasters.

Minimize environmental pollution by receiving information such as air condition and amount of waste.

Increase energy management efficiency by receiving energy-related information.

The monitoring and control system by remote measurement according to the prior art cannot diagnose and judge the sensor's own measurement and control management by itself, and has limited problems due to the control and control of the central control system. By providing the function to measure the bay, it is impossible to judge the surroundings of the measurement environment, and there is a problem that there is no ability to respond to the crisis.

On the other hand, an embedded device accepts this signal in the form of an analog input when it contains an amplifier function or creates a standardized voltage and current signal.

The signal received by the embedded device is converted into a digital signal, and the computer function of the embedded device generates valid data that affects the quality and performance of the machine, and analyzes the data according to the algorithm. Therefore, the result is transmitted to the upper computer system.

Informatization requires sensor technology, embedded device technology, amplification technology, protocol implementation technology, communication and network technology, intelligent software development technology, and sensor-based embedded device technology.

Synergy through such information technology provides new business opportunities to companies that apply informatization in various forms and companies that build informatization.

Information and communication technology refers to a technology in which existing general-purpose information and communication technologies are fused as contents in areas where information has not been made, rather than technologies for creating new ones.

The information technology through the sensor-based embedded device is the commercialization of the gateway for information integration through the sensor and the embedded device and related firmware, and the commercialization of the embedded device, New business opportunities are created by enabling the commercialization of various products such as the commercialization of information and communication technologies in connection with mobile devices and the commercialization of amplifier technology for fine signals such as pressure and temperature.

In addition, the ICT Solution refers to information technology for a method of collecting and processing data and communication technologies such as various communication, network, and interface.

On the other hand, the method of the Internet terminal is interlocked with M2M (Merchine to Merchine) equipment 1: 1 to acquire information of all measuring instruments, and the information created through the necessary processing through any smartphone, PAD, or other mobile device. It is a method of monitoring and controlling contents.

Therefore, in the present invention, the Internet of Things and an embedded-based monitoring system are proposed, and through this, an embedded or sensor-based measurement, data judgment and diagnosis, and control process can be exchanged in real time by an administrator or user, or abnormal. It is possible to provide a system that can reduce the error in measurement by quickly managing the response procedure by the administrator or the user in a specific situation, and by thoroughly monitoring the measurement environment.

Hereinafter, preferred embodiments of the IoT-based embedded monitoring system according to the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall configuration diagram of an IoT-based embedded monitoring system according to a first embodiment of the present invention.

As shown in FIG. 1, the IoT-based embedded monitoring system according to the first embodiment of the present invention includes a field detection sensor unit 100, an embedded IOT transmission terminal 200, an IOT display device 300, and an embedded controller ( 400), a mechanical equipment 500, and a cloud server 600.

Specifically, the on-site detection sensor unit 100 is configured to be installed in the field and performs a function for transmitting communication packet data packetized in the form of a communication protocol to the embedded IOT transmission terminal 200.

To this end, the on-site detection sensor unit 100 may configure a communication packet data generation module to generate communication packet data.

That is, the communication packet data generation module is configured to generate communication packet data including a header field, an ID field, a block field, a tail field, and a MC field.

In addition, the field detection sensor unit 100,

It is characterized in that it includes at least one or more of a flow meter, an ammeter, a water level meter, a voltmeter, a water level meter, a sound sensor, a vibration sensor, a temperature sensor, a water quality sensor, a salinity sensor, and an air quality sensor.

The flow meter is a sensor for measuring the flow rate, the ammeter is a sensor for measuring the current, the water meter is a sensor for measuring the water level, the voltmeter is a sensor for measuring the voltage, and the open water meter is a sensor for measuring the opening degree , And the temperature sensor is a sensor for measuring temperature, the water quality sensor is a sensor for measuring water quality, the salinity sensor is a sensor for measuring salinity, and the air quality sensor means a sensor for measuring air quality.

In addition, the sound sensor is a sensor for measuring the ambient sound, for example, to measure the sound generated in the water gate or pump.

The vibration sensor is a sensor for measuring vibration, for example, to measure vibration generated in a water gate or a pump.

The causes of vibration are representative of the most common causes of vibration in repair facilities, such as vibration due to poor balance, vibration caused by friction, vibration caused by misalignment, self-excited vibration, nonlinear vibration, and thermal characteristics. And vibration due to piping or foundation.

Therefore, it is possible to check the presence or absence of an abnormality in the repair facility through the introduction of the vibration sensor, so that the operating state is always checked before the failure occurs.

In addition, the embedded IOT transmission terminal 200 collects communication packet data periodically transmitted from the field detection sensor unit.

For example, if the flow sensor, ammeter, water level meter, sound sensor, vibration sensor, and temperature sensor are configured as the field detection sensor unit 100, communication packet data periodically transmitted from them are collected.

In the present invention, by configuring the communication packet data to include a header field, an ID field, a block field, a tail field, and a CC field, it is possible to prevent loss and hacking of raw data transmitted from sensor units, and embedded IOT. In the transmitting terminal, it is possible to determine from which sensor unit the data is transmitted through the ID field, and to check the data information through the block field.

Through this, because the embedded IOT transmission terminal stores and manages device ID information of the field detection sensor unit 100 in its jurisdiction, it does not store and process detection information provided by other sensor units other than the device ID information. In the same way, since the cloud server stores and manages device ID information of the embedded IOT transmission terminal under its control, it does not store and process detection information provided by other embedded IOT transmission terminals other than the device ID information. do.

In addition, the embedded IOT transmission terminal 200 interprets and classifies communication packet data, converts it into digital values, stores it, and transmits the communication packet data to a cloud server.

That is, the communication packet data is analyzed and classified according to each device ID, and the measured value in the classified data is converted into a digital value and stored, and the communication packet data is transmitted to the cloud server at the same time.

In addition, when the converted digital value and the preset measurement range are out of range, it is determined as an abnormal signal and an alarm flag is processed in the corresponding communication packet data to be transmitted to the cloud server.

For example, in the case of a water gauge, measurement range range information of 'water level 1M-1V to water level 10M-5V' is set and stored.

At this time, if the measured value is 0V or 6V, it can be judged as an abnormal state because it is outside the measurement range range value.

In this case, if an alarm flag is processed in the communication packet data and transmitted to the cloud server, the alarm flag exists when the communication server interprets the communication packet data. It is possible to display a pop-up window on the display screen so that prompt action can be taken, or to inform the current status to the person in charge.

In addition, the stored communication packet data or the alarm flag-processed communication packet data is transmitted to the IOT display device, through which the current status is notified to the person in charge at the site or the people in the vicinity, so that follow-up actions can be taken. It is to be.

In addition, the control communication packet data matching the control signal to the alarm flag-processed communication packet data is transmitted to the embedded controller. For example, a control communication packet data generated by generating an operation signal for a hydrogate switch and matching it to the communication packet data By transmitting the to the embedded controller, the embedded controller provides an operation signal to the hydro gate switch to operate accordingly.

In addition, when the user generates a remote control signal according to the current water level, the cloud server acquires it to generate remote control communication packet data, transmits it, and embeds the remote control communication packet data transmitted from the cloud server. It is transmitted to the controller, and the embedded controller operates the hydrogate switch, which is the corresponding mechanical equipment, with reference to this.

Then, the IOT display device 300 interprets and classifies the communication packet data or the alarm flag processed communication packet data transmitted from the embedded IOT transmission terminal 200, and then displays them through a display panel. To perform the function.

Through this, it is possible to inform the current status to the person in charge at the site or those located in the vicinity so that follow-up actions can be taken.

For example, the measurement values included in the communication packet data are interpreted, and the measurement values such as temperature-25 degrees, water level-15 meters, etc. are displayed through the display panel, or the communication packet data processed with the alarm flag is analyzed. Water level-30 meters of measurement value and follow-up information according to the processing of the alarm flag are generated and displayed on the display panel by generating information such as the operation of the water gate switch and warning broadcast wind to the general public.

Then, the embedded controller 400 receives the control communication packet data transmitted from the embedded IOT transmission terminal 200, analyzes and classifies it, and then transmits any one of DO, AO, and serial signals to the mechanical equipment 500. A function for transmitting and controlling a signal is performed.

That is, since the control signal is included in the control communication packet data, the embedded controller determines whether a control signal exists when interpreting the control communication packet data.

At this time, if a control signal is present, it determines the mechanical equipment corresponding to the control signal and transmits any one of DO, AO, and serial signals corresponding to the control signals of the corresponding mechanical equipment.

For example, in the case of a water gate switch, the AO signal is generated and provided to the water gate switch to open the water gate.

In addition, the cloud server 600 collects communication packet data or communication packet data processed by an alarm flag periodically transmitted from the embedded IOT transmission terminal 200, and collects the communication packet data or communication signal data processed by the alarm flag. After analysis and classification, it is stored in the cloud storage.

That is, since communication packet data periodically acquired in real time includes a header field, an ID field, a block field, a tail field, and a CLC field, when interpreting it, it is possible to classify which field is provided from a sensor unit installed and configured. There will be.

Accordingly, the classified communication packet data is stored and processed in a data field provided for each site or sensor unit.

In addition, since a separate remote program is installed and configured, when the administrator loads the remote program and performs control for a specific machine, the remote control communication packet data matching the control signal input by the administrator is generated to generate the corresponding embedded IOT. By transmitting to the transmission terminal 200, it is possible to perform remote control.

As described above, in the present invention, the communication packet data packetized in the form of a protocol is configured to be exchanged.

At this time, as shown in Figure 4, the communication packet data,

It is characterized by including a header field, an ID field, a block field, a tail field, and a MC field.

Specifically, the header field includes STX indicating a protocol start and Code information indicating a protocol classification code,

The ID field includes ID length indicating the ID length and ID information indicating the device ID,

The block field includes block length indicating block length, CMD indicating command classification, type indicating detailed command classification, AK / NK indicating data status, data information including Json data and bytes data,

The tail field includes a code indicating a protocol end code and ETX information indicating a protocol end,

The CC field is characterized by including CRC information indicating the SUM value from the header field to the tail field.

Since the header field includes STX indicating a protocol start and Code information indicating a protocol classification code, the embedded IOT transmission terminal 200, the IOT display device 300, the embedded controller 400, and the cloud server 600 should be interpreted. It is possible to know the start of the protocol to be performed, and when interpreting, it can be accurately and quickly analyzed, and it is possible to provide the convenience of classification because the protocol classification code is known.

In addition, since the ID field includes ID length indicating the ID length and ID information indicating the device ID, the measurement data can be stored or updated based on the device ID using the device ID as an identifier.

In addition, the block field includes block length indicating block length, CMD indicating command classification, type indicating detailed command classification, AK / NK indicating data status, data information including Json data and bytes data. It is possible to include information such as various measurement data, control data, and alarm flags.

In addition, the tail field includes a code indicating a protocol end code and ETX information indicating a protocol end.

Therefore, it is possible to know the end of the communication packet data so that it is possible to determine the start of the significant data and the position of the last byte.

In addition, since the CR field includes CRC information informing the SUM value from the header field to the tail field, it is possible to confirm an error or modification of communication packet data.

2 is a block diagram of an embedded IOT transmission terminal 200 of an IoT-based embedded monitoring system according to a first embodiment of the present invention.

As shown in FIG. 2, the embedded IOT transmission terminal 200 includes a data collection unit 210, a data processing unit 220, a data storage unit 230, an alarm flag processing unit 240, and an IOT communication packet data transmission unit. It will be configured to include 250.

In detail, the data collection unit 210 collects communication packet data periodically transmitted from the field detection sensor unit, and the data processing unit 220 analyzes the collected communication packet data to classify the data. Thereafter, the classified data is converted into digital values and stored in a data storage unit, and the collected communication packet data is transmitted to a cloud server.

For example, by checking the ID, it interprets whether it is the on-site sensor unit managed by the corresponding embedded IOT transmission terminal, checks what kind of data is stored in the block field, converts it to a digital value, and stores it. It is stored in the department.

In general, the classified data is sampled every 1 ms period, and the peak value from which 100 values are extracted is detected, and the average and frequency of the detected peak value are used to process the signal as a constant size.

Thereafter, the signal processed with the input analog voltage (DC 1-5V) and current (4-20mA) is converted into a digital value that can be determined by the data processing unit.

Accordingly, the data storage unit 230 stores communication packet data and converted digital values provided by the data processing unit, and stores alarm flag processed communication packet data processed by the alarm flag processing unit.

In addition, the alarm flag processing unit 240 determines an abnormal signal when the digital value converted by the processing of the data processing unit and a preset measurement range are out of order and processes an alarm flag in the corresponding communication packet data to be transmitted to the cloud server. do.

For example, in order to set the measurement range, a selection icon is provided to select either an output value in the DC 1V to 5V range or an output value in the 4mA to 20mA range.

At this time, when the administrator selects an output value within the range of DC 1V to 5V, the minimum measurement value to be matched to DC 1V, which is the minimum value of the selected output value, is set. In the case of a water level meter, the level 1M is input.

In addition, the maximum measurement value to be matched to the maximum value of 5V, which is the selected output value, is set, and the water level 10M is input.

That is, by providing an input page for setting the measurement range range for each sensor, the measurement range range for each sensor is set.

Therefore, if the measured value is 0V or 6V, it can be determined as an abnormal state because it is out of the measurement range value, and an alarm flag is processed in the corresponding communication packet data and transmitted to the cloud server.

The alarm flag processing is a method of processing to notify that the communication packet data includes an event signal, and the terminal of the receiving side that receives it provides a pop-up window when interpreting it.

Then, the IOT communication packet data transmission unit 250 is a first mode, an alarm flag for transmitting the communication packet data or the alarm flag processed communication packet data stored in the data storage unit to the IOT display device using the Internet of Things wireless communication method One or more of the second mode of transmitting the control communication packet data matching the control signal to the processed communication packet data to the embedded controller, and the third mode of transmitting the remote control communication packet data transmitted from the cloud server to the embedded controller. The function to perform is performed.

For example, in order to perform the first mode, the IOT communication packet data transmission unit 250 displays IOT communication packet data or alarm flag processed communication packet data stored in the data storage unit using the IoT wireless communication method. Will be transmitted.

That is, as described above, the communication network can be used more and more advanced and inexpensive, but various control systems do not currently use the advanced and inexpensive communication method, so users are expensive, and there are limitations inevitably to use a dedicated line communication network that is difficult to build. .

To solve this, the IOT communication packet data transmission unit 250 of the present invention is an embedded method capable of interfacing with the LTE-M wireless network communication unit of the LTE-M communication method or the NB-IoT wireless network communication unit of the NB-IoT communication method. The platform will be loaded.

Accordingly, the embedded IoT communication terminal 200 and the cloud server are packaged by packetizing data in the form of a communication protocol through the Internet of Things (IoT) wireless communication unit (LTE-M, NB-IoT). 600).

3 is a block diagram of a cloud server 600 of an IoT-based embedded monitoring system according to a first embodiment of the present invention.

As shown in FIG. 3, the cloud server 600 includes a cloud server data collection unit 610, a cloud server data processing unit 620, a cloud storage unit 630, a cloud server communication packet data transmission unit 640, and a cloud It is configured to include a server screen display unit 650, an alarm processing unit 660.

In detail, the cloud server data collection unit 610 collects communication packet data periodically transmitted from the embedded IOT transmission terminal 200 or communication packet data processed by an alarm flag, and the cloud server data processing unit 620 After classifying the collected communication packet data or the alarm flag-processed communication packet data, the classified data is converted into a digital value and stored in a cloud storage unit.

The process of classifying the communication packet data and converting the classified data into digital values has been described in detail in the embedded IOT transmission terminal 200, so a detailed description thereof will be omitted.

The cloud storage unit 630 stores communication packet data provided by the cloud server data processing unit and converted digital values, and stores communication packet data processed by an alarm flag.

In addition, the cloud server communication packet data transmission unit 640 generates a remote control communication packet data matching the control signal when obtaining a control signal input by the administrator to transmit to the embedded IOT transmission terminal 200. .

For example, by generating an operation signal of the hydrogate switch, and transmitting the remote control communication packet data matched to the communication packet data to the embedded IOT transmission terminal 200, the embedded IOT transmission terminal 200 analyzes this to analyze the embedded controller. The control signal for the corresponding machine is transmitted.

Accordingly, an operation signal is provided to the gate switch to operate.

In addition, even if it is not an abnormal signal, if the user normally generates a remote control signal according to the current water level, the cloud server communication packet data transmission unit 640 acquires this to generate remote control communication packet data, and embeds it. It is transmitted to the transmission terminal 200, and the embedded IOT transmission terminal 200 interprets this to provide a control signal to the embedded controller, and the embedded controller refers to this to operate the corresponding mechanical facility, the hydrogate switch.

In addition, the cloud server screen display unit 650 displays the location information for each field detection sensor unit on the screen, and displays communication status, power status, and measurement values on the screen according to data for each field detection sensor unit stored in the cloud storage unit. Ordered.

For example, the location information of the temperature sensor installation called 'Nakdong River estuary bank first drainage gate' is displayed on the screen, and the communication status of the sensor (for example, the communication status is good) and the power status (for example, the power status is good). , The measured value (for example, temperature 28 degrees) is displayed on the screen.

In addition, the alarm processing unit 660 analyzes the alarm packet-processed communication packet data, pops up the location information and measurement values of the corresponding field detection sensor unit on the screen, and generates an alarm with the person in charge terminal 700 in charge of the relevant field detection sensor unit It performs the function of sending information and enabling rapid processing.

For example, when the temperature value is higher than the normal temperature value, the information of the location detection sensor unit information such as 'Nakdong River Estuary Bank 1st Drain Gate Gate', 'Pump Temperature 40 °', and 'Person-010-123-4567' is displayed. And the location information and measurement values are transmitted to the corresponding person in charge.

On the other hand, in the alarm occurrence information sent to the person in charge,

It is characterized by including the type information of the site detection sensor unit, the measurement range range information of the site detection sensor unit, and the installation location information of the site detection sensor unit.

That is, it will include information such as 'pump temperature sensor', 'temperature range 25 degrees to 38 degrees', and 'the first drain gate of the Nakdong River estuary bank'.

On the other hand, according to another additional aspect, the embedded IOT transmission terminal 200,

When the communication packet data including the communication automatic recovery event signal is obtained from the cloud server 600, the communication packet data existing between the communication disconnection time and the communication resume time is extracted from the data storage unit 230, and then extracted. It may be configured to further include; monitoring information generation unit within the communication interruption range for providing the communication packet data to the cloud server 600.

Specifically, in the case where the monitoring information generation unit within the communication disconnection range acquires the communication automatic recovery event information from the cloud server 600, between the communication disconnection time and the communication restart time included in the communication packet data including the communication automatic recovery event signal. Existing communication packet data is extracted from the data storage unit 230.

For example, if the communication disconnection time is 9 am on July 21, 2019, and the communication resume time is 10 am on July 21, 2019, the communication packet data existing between the communication disconnection time and the communication resume time is displayed. It is extracted from the data storage unit 230.

On the other hand, according to another additional aspect, the cloud server 600,

A sensor map map DB storing sensor map map information;

A sensor for obtaining sensor map map information from the sensor map map DB, extracting location information through the device ID of the corresponding facility from data stored in the cloud storage unit 630, mapping it on the sensor map map DB, and displaying it on the screen It can be configured to include; map map location display unit.

Specifically, the sensor map map DB stores sensor map map information, and the sensor map map location display unit acquires sensor map map information from the sensor map map DB and corresponds to data stored in the cloud storage unit 630. The location information through the device ID of the facility is extracted and mapped onto the sensor map map to be displayed on the screen.

For example, after extracting the location information through the device ID of the facility for recycling the rainwater, it is mapped to the corresponding location on the sensor map map.

In addition, if necessary, the alarm occurrence history may be popped up on the screen, and configured to promptly notify the administrator through a warning sound or SMS (text service).

On the other hand, according to another additional aspect, the cloud server 600,

When obtaining the selection information for any one facility, it may be configured to further include; a selected facility detection information display unit for extracting the detection information for the facility from the cloud storage unit 630 to display on the screen.

For example, when the facility is a storage tank, when an administrator selects a storage tank that is a facility having an ID: 1 -Storage tank, the unique ID of the storage tank is extracted, and the detection data using the unique ID as the cloud storage unit It is extracted from (630).

Therefore, it is possible to check the current sensing state information.

If, as a monitoring means, a video camera unit is configured, it is possible to check the current state of the storage tank as a video.

On the other hand, according to another additional aspect, the cloud server 600,

If it is not possible to obtain a response signal for the check signal from the embedded IOT transmission terminal 200, it is determined as a communication loss, and extracts the time at which the check signal is transmitted after receiving the final response signal, and periodically provides a check signal. After extracting the time to receive the response signal for the check signal, the detection information for each of the field sensor units is present in the section from the time when the check signal is transmitted after receiving the final response signal to the time when the response signal for the check signal is received. It may be configured to generate a communication packet data including the communication automatic recovery event data requesting, and to provide the generated communication packet data to the embedded IOT transmission terminal;

Specifically, the automatic recovery processing unit for the missing detection information acquires a response signal to the check signal periodically with the embedded IOT transmission terminal.

For example, a check signal is transmitted in increments of 5 minutes, and a response signal is obtained, so that the communication is in a normal operating state.

However, when communication is lost, after the final response signal is received, the time at which the check signal is transmitted is extracted, and periodically the check signal is provided, but after the time at which the response signal for the check signal is received is extracted, the final response signal is extracted. It generates communication packet data including communication auto-recovery event data requesting monitoring information for each monitoring means existing in a section from the time when the check signal is transmitted to the time after receiving the check signal and the response signal response time.

For example, if a check signal is sent at 9 am on July 21, 2019, and a response signal cannot be obtained, it is determined as a communication loss, and the start time of communication loss is July 20, 2019 You will judge at 9 o'clock.

Thereafter, a check signal is periodically provided in units of 5 minutes, and a time for receiving a response signal for the check signal is extracted.

For example, if a response signal for a check signal is received at 10 am on July 20, 2019, it is determined as a communication resumption time.

Therefore, by generating communication packet data including communication auto-recovery event data requesting detection information for each field detection sensor unit existing in the time period from 9:00 AM on July 20, 2019 to 10:00 AM on July 20, 2019, This is to be provided to the corresponding embedded IOT transmission terminal 200.

At this time, the embedded IOT transmission terminal 200 extracts the detection information for each field detection sensor unit existing between the corresponding communication disconnection time and the communication resume time from the data storage unit 230.

That is, the detection information for each field detection sensor unit such as water level 1-5CM, water level 2-3CM, etc. is extracted and transmitted to the cloud server 600 to update and process the data field having the unique ID of the corresponding facility stored in the cloud storage unit 630. Is done.

As described above, by configuring the embedded IoT transmission terminal 200 and applying IoT and CPS (Cyber Physical Systems) technology, sensing, comparison, analysis, judgment, autonomous control, and when an event occurs, wired Internet or IoT By sending the alarm flag-processed communication packet data to the cloud server 600 through a communication network (LTE-M or NB-IoT), an administrator who resides in the integrated monitoring center can monitor the current status of the facility. Will be exerted.

In addition, it is expected to advance the technology to ensure intelligent automatic setting, autonomous control, and optimal operation by sensing and analyzing the system itself without the administrator, away from the operation by the experience of the existing administrator.
