Environmental radiation data transmission system using science roller {DATA TRANSMISSION SYSTEM FOR ENVIRONMENTAL RADIATION USING THE ScienceLoRa}

The present invention relates to a system for transmitting environmental radiation data using ScienceLoRa.

Specifically, by using Science Roller, the IoT Network of the National Science and Technology Research Network (KREONet) provided by the Korea Institute of Science and Technology Information (KISTI), the IoT network is the primary communication network, and the existing CDMA The network is a secondary communication network, which increases the availability by redundant networks, enables enhanced security communication provided by ScienceLoRa, and provides low-cost communication through the use of ScienceLoRa, a national network, to an environmental radiation data transmission system.

The Korea Institute of Nuclear Safety and Technology (KINS) is operating 206 environmental radiation monitors (HPIC, NaI and LaBr3) at 171 environmental radiation monitoring stations nationwide as of June 2020, starting with 4 branches around the nuclear power plant in 1992. The pressurized ionizer-type monitor (hereinafter referred to as “HPIC”), which is performing the monitoring role, is currently in operation with the 3rd generation RSDetection model through the 1st and 2nd generations.

The existing environmental radiation monitoring system consists of a monitor corresponding to a data sensor, a communication modem that transmits the data received by the data sensor, a communication company base station, a communication company relay server, and KINS’s National Environmental Radiation Automatic Monitoring Network (IERNet) server. Consists of.

However, since the monitor and the communication modem (1st, 2nd, or 3rd generation monitor) are configured in the form of a communication modem and the section between the monitor and the communication modem uses the serial communication (RS-232C) method, the communication between the 1st and 2nd generation monitors In the case of modem, there is no problem in terms of data collection and monitor management, but the communication modem of the 3rd generation monitor is operated in a compatible mode with the 1st and 2nd generation monitors, so there are many problems in terms of data collection and monitoring device management when a problem occurs.

This is the engine that the 3rd generation monitor stores data, and the default is TCP/IP, which is equipped with a SQL database and guarantees communication performance, but operates in a backward compatibility mode for mixed operation with the 1st and 2nd generation monitors. Because.

In addition, due to the recent investment in 2G communication base station infrastructure and delays in service of related telecommunication companies, there is a great difficulty in collecting IERNet data. Recently, Sejong ('18.5.29 ~ 31) including the Samcheok branch ('18.6.25 ~ 6.29) , Hebuk ('18.4.20 ~ 27), Wondeok ('17.9.15 ~ 26), Pocheon ('17.9.12 ~ 20) had serious obstacles to data collection. Considering the previous cases, it is difficult to expect stable service in the future. , Among the IERNet collection errors in 2017, 142 cases such as modem and communication company failures are up to 46% of the total (311 cases).

For the above reasons, to solve the current communication problems for IERNet, and to promote public safety by actively using it for public information disclosure through securing communication network availability, strengthening security, and improving data collection rate by applying IoT-based new technology. ScienceLoRa technology application feasibility evaluation (Project Feasibility Evaluation) was completed in May-June, and in December, past communication failure points such as Samcheok and Sejong were conducted through a lab-test on the 3rd generation monitor in collaboration with KISTI, an IoT-based technology cooperation organization. The stress-test was also completed, and the development of the environmental radiation data transmission system using ScienceLoRa was completed in '19, and the test has been operated at 21 branches nationwide since '20.

Terms or words used in this specification and claims should not be construed as being limited to their usual or dictionary meanings, and that the inventor can appropriately define the concept of terms in order to describe his own invention in the best way. Based on the principle, it should be interpreted as a meaning and concept consistent with the technical idea of the present invention.

Therefore, the embodiments described in the present specification and the matters shown in the drawings are only the most preferred embodiments of the present invention, and do not represent all the technical spirit of the present invention. It should be understood that there may be water and variations.

Hereinafter, prior to description with reference to the drawings, matters that are not necessary to reveal the gist of the present invention, that is, known configurations that can be obviously added by those skilled in the art are not shown or specifically described. Make the note clear.

The present invention relates to an environmental radiation data transmission system using a science roller.

Specifically, by using Science Roller, the IoT Network of the National Science and Technology Research Network (KREONet) provided by the Korea Institute of Science and Technology Information (KISTI), the IoT network is the primary communication network, and the existing CDMA The network is a secondary communication network, which increases the availability by redundant networks, enables enhanced security communication provided by ScienceLoRa, and provides low-cost communication through the use of ScienceLoRa, a national network, to an environmental radiation data transmission system.

1 shows a system for transmitting environmental radiation data using a science roller according to the present invention.

The environmental radiation data transmission system using a science roller according to the present invention according to FIG. 1 of the accompanying drawings comprises: a plurality of monitors for collecting environmental information on radiation from a remote location; A plurality of communication units performing a communication function so that each monitor can communicate with the server; A gateway that manages a plurality of communication units as a group and functions to transmit information of the communication unit to a server; And a server that collects environmental information of the monitor and performs a function of monitoring the status of the monitoring site and remote control.

In this case, a plurality of gateways that communicate while managing a plurality of communication units may be provided according to the number of communication units.

That is, assuming that one gateway manages, for example, five communication units as a group, if there are 20 monitors including the communication unit, four gateways may be configured. Alternatively, one gateway may have 5 communication units as a group, but manage 4 groups.

The server is configured as shown in FIG. 2 of the accompanying drawings for the above-described functions.

2 is a block diagram showing a server configuration of an environmental radiation data transmission system using a science roller according to the present invention.

The communication module of the server performs the function of allowing the server to communicate with the gateway. At this time, the communication module enables the identification of the monitor by using the identification information included in the environmental information received from the monitor, and for this purpose, the communication module may be configured to include a monitoring device determination unit. Or, it is possible to implement the monitoring board judgment module separately in the server.

The information of the monitor determined through the identification information of the monitor is household information, and it is determined whether the monitor is a first-generation monitor, a second-generation monitor, or a third-generation monitor.

The monitor for monitoring environmental information related to radiation includes: an HPIC for monitoring ion ionization chamber type radiation; There are LaBr3 and NaI, which perform high-resolution monitoring and scintillation radiation monitoring, and each of them is classified into first to third generations according to the time of manufacture.

In general, the 1st and 2nd generation monitors communicate using only the RS-232C communication method, and the 3rd generation monitor communicates using the RS-232C and TCP/IP communication methods. In addition, these monitors perform communication using a 2G communication modem using a base station. In the case of the first and second generation monitors, there is no problem in terms of data collection and monitor management, but the third generation is in a compatible mode with the previous generation monitor. As it works, there are many problems in terms of data collection and management of the monitor. This is because the 3rd generation monitor has a SQL database as an engine that stores information and uses TCP/IP as the default communication method.

In addition, due to the existing 2G communication base station-based facilities, difficulties have arisen in data collection, especially in areas where communication is insufficient.

When the server's generation is determined by the above-described monitoring device determination function, the 1st and 2nd generation monitors communicate with the existing RS-232C communication method, and the 3rd generation monitors are RJ-45, UTP5, etc. Let communication take place.

To this end, the communication module may include a conventional communication connection unit and a network communication connection unit, and the conventional communication connection unit functions to allow the first and second generation monitors to communicate with the conventional RS-232C communication method, and the The network communication connection unit functions to enable the household monitor to communicate such as RJ-45·UTP5 or higher. At this time, since the expression of UTP5 or higher means an abnormality in the communication standard, it will be clearly understood by those of ordinary skill in the art.

In addition, when the monitor status check module of the server receives environmental information including radiation information, identification information, and monitor status information transmitted by the monitor through the communication module, the status of the monitor is based on the monitor status information among the environmental information. Performs the function of checking.

At this time, the monitor status information is to include all information required to check the monitor predicted by a person skilled in the art.

At this time, the monitor status check module stores information about when the inspection target is in a normal state in order to check the status of the monitor based on the monitor status information of the received environmental information, and includes a normal status information storage unit for this purpose. Can be configured to

In addition, the monitoring module of the server performs a function of outputting monitoring information to a terminal accessible to the server based on the environmental information received from the monitor.

In this case, the monitoring information includes information based on radiation information of environmental information; It may be information based on the monitor status information, and these information may be continuously output and monitored at a certain period or in real time.

In addition, the interlocking module of the server functions so that the instrument axis server used before the system according to the present invention was constructed and the server according to the present invention can be interlocked. It may be interlocked, or a physical element such as hardware of a mechanical axis server may be combined with the server according to the present invention to be interlocked. This can be implemented by a person skilled in the art, and is configured based on the technology that can be implemented at the time of filing of the present invention.

In addition, the server's monitor remote management module functions to remotely control and manage all monitors communicated with the server. At this time, as an example of control management, there may be a reset (reboot) of the monitor, which is to use the existing RJ-45 interface for the first and second generation monitors according to the generation of the monitor determined by the communication module, and the third generation. In the case of a monitor, it can be implemented to issue a control command to the monitor in a serial communication method from the server using the SQL engine.

To this end, the above-described communication module is preferably implemented to enable RS-45 communication for serial communication and communication for use of the SQL engine in addition to the above-described communication method for receiving information from the monitor.

In addition, the server may further include a firmware access module as shown in FIG. 2 of the accompanying drawings. The firmware access module functions to allow the server to access the firmware of the monitor through the serial communication and modify the firmware. That is, the manager (or operator) located at the site where the server is built can modify the firmware of the monitor through the server.

In addition, the monitoring device event information inquiry module of the server functions to allow the administrator to inquire the status (event) of a specific monitoring device during a certain period based on the monitoring device status information among the environmental information received from the monitoring device.

For example, when an administrator sets a predetermined period through a terminal connected to the server and sets a monitor to be inquired, it functions to inquire event information during the period of the monitor.

Meanwhile, depending on design conditions, a gateway for managing a plurality of communication units as a group may be configured as follows for smooth communication with communication units provided at different locations based on the gateway.

That is, even if the communication unit is managed as one group, there may be a difference in communication speed depending on the distance from each communication unit, and even if the environment information is received and transmitted to the server in real time, it is omitted due to the continuously transmitted information. Since there may be environmental information that cannot be transmitted to the server, a predetermined rule is set so that environmental information can be transmitted to the server without omission.

Hereinafter, a case where the gateway manages five communication units as one group will be described as an example. At this time, it is emphasized that if there are fewer than 5 communication units per group or more than 5 communication units per group, there is room for interpretation to correspond thereto.

First, the gateway is not shown in the drawing, but the communication module; Distance weight application module; Time weight application module; Table production module; And a small value priority transmission module.

The communication module performs a function of transmitting the environmental information received from the communication unit to the server. At this time, the communication module functions for each cycle (cycle) when transmitting the environment information received per group and the received environment information.

For example, if one cycle is not finished, the next environment information is not transmitted to the server in a state that can be received. When one cycle is completely finished, a cycle is formed again based on the next environment information and information is processed.

The distance weight application module performs a function of applying a weight based on a distance separated from the gateway to each communication unit (or monitor).

At this time, since the distance to each communication unit does not change in the distance of the communication unit, it may be input based on the initially designed information.

As for the weight by distance by the distance weight application module, a weight of 10% is sequentially applied from the farthest distance to the nearest distance.

The time-weighted value application module performs a function of applying a weight for each communication unit to the environmental information received through the gateway by time.

At this time, the weight for each time is to apply a weight of 20% for each time.

The table production module performs a function of producing a table for environmental information for 1 cycle to which weights are applied by the distance weight application module and the time weight value application module.

For example, an example of manufacturing a table is shown in [Table 1].

※ The vertical axis in [Table 1] increases the distance downward.

※ The horizontal axis in [Table 1] shows that the reception time is later as it goes to the right.

Referring to [Table 1], in the table, a weight of 10-50% for each distance is applied to the environmental information received in the first time zone. And for the environmental information received in the next time zone, the environmental information received from the communication unit located at the farthest distance is applied as 30%, 20% added to the 10% in the previous time zone, and after that, a weight of 10% is applied again. In other words, for the environmental information of the same communication unit in the previous time period, the table is created to increase the weight by 20%.

[Table 1] defines 1Cycle to receive environmental information for a total of 4 time zones.

When a table is produced as shown in [Table 1], the small value priority transmission module functions to transmit the environmental information of the small value to the server through the communication module in order.

By functioning in this way, it is possible to solve the problem of omission even if the environmental information received from the communication unit is continuously received.

What has been described with reference to the drawings above is a description of only the main matters of the present invention, and it is obvious that the present invention is not limited to the configuration of the drawings as various designs are possible within the technical scope.
