Description

Method for managing device location information in LPWAN (Low Power Wide Area Network) environment, system and non-transitory computer-readable recording medium (METHOD, SYSTEM AND NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM FOR MANAGING POSITION INFORMATION OF DEVICE BASED) ON LPWAN}

The present invention relates to a method, a system, and a non-transitory computer-readable recording medium for managing location information of a device in a Low Power Wide Area Network (LPWAN) environment.

In recent years, as various industries related to autonomous driving (flying) such as autonomous vehicles and drones emerge, interest in high-precision positioning technology is increasing.

Location information based on GNSS (Global Navigation Satellite System), which is generally used in such positioning technology, has some error due to refractive effects and delay effects occurring in the ionosphere and convective layers, so for high-precision positioning. There is a need to minimize errors.

Accordingly, in Korea, the National Geographic Information Service operates a reference station that generates position correction information based on the accurate position information of the reference station, and supports high-precision positioning by providing such position correction information.

When LPWAN is used to provide such position correction information to a moving object (autonomous vehicle, drone, etc.), high-precision positioning is possible on a moving object within a wide coverage, so it can be used for various purposes such as autonomous driving, drone swarm flight, and precision landing. It is possible.

As an example of the prior art for this, the technology disclosed in Korean Patent Publication No. 10-1885612 may be exemplified. According to this, the location error information for each reference station is received from the DGPS web server and provided by the wide area communication network provider. It is characterized by including a management server that provides to a lower class terminal device through a paid public LPWAN and collects and manages facility information and positioning information from the lower class terminal device.

However, according to the techniques introduced so far, including the prior art described above, a fee for use of position correction information must be paid to the organization operating the reference station, or the distance between the reference station and the mobile body (or mobile station (rover)) is long. In this case, there is a problem that a relatively less precise positioning result is caused as the positioning error increases.

In addition, since the location correction information in the form of RTCM (Radio Technical Commission for Maritime) generated by the reference station generally reaches 50 to 100 bytes (maximum 1023 bytes), it is not necessary to set a separate communication channel. In the case of transmission using the basic communication channel of, there is a problem that communication of other terminals (eg, reporting of sensing results) is disturbed.

Here, RTCM is a DGNSS (Differential GNSS) message format determined by RTCM SC (Special Committee)-104, and means a binary data protocol including position correction information.

Accordingly, the present inventor(s) is a method for managing location information of a device in an LPWAN environment, and when GNSS-based reference location information is determined based on the location of a gateway, the location of the above gateway is based on the reference location information. This is to propose a technology for generating correction information, transmitting the position correction information to the device through a communication channel by the gateway, and managing the communication channel.

An object of the present invention is to solve all the problems of the prior art described above.

Another object is to determine a gateway for transmitting position correction information to the above device and a communication channel of the gateway for transmitting the position correction information based on at least one.

A typical configuration of the present invention for achieving the above object is as follows.

According to an aspect of the present invention, when reference location information based on a Global Navigation Satellite System (GNSS) is determined based on the location of the gateway, the gateway generating location correction information based on the reference location information, the gateway A method is provided that includes transmitting the location correction information to a device through a communication channel, and reporting, by the gateway, first status information regarding the gateway to a management server.

Gateway configuration

Hereinafter, the internal configuration of the gateway 300 performing important functions for the implementation of the present invention and the functions of each component will be described.

According to an embodiment of the present invention, the location information management unit 310, the location correction information transmission unit 320, the status information report unit 330, the communication unit 340, and the control unit 350 are It may be a program module that communicates with the system. Such a program module may be included in the gateway 300 in the form of an operating system, an application program module, or other program module, and may be physically stored in various known storage devices. Also, such a program module may be stored in a remote storage device capable of communicating with the gateway 300. Meanwhile, such a program module includes routines, subroutines, programs, objects, components, data structures, etc. that perform specific tasks or execute specific abstract data types according to the present invention, but is not limited thereto.

Meanwhile, although the gateway 300 has been described as above, this description is exemplary, and at least some of the functions or components required for the gateway 300 are realized or included in an external system (not shown) as necessary. It is obvious to a person skilled in the art that it may be possible.

First, the location information management unit 310 according to an embodiment of the present invention, when GNSS-based reference location information is determined based on the location of the gateway 300, generates location correction information based on the reference location information. Function can be performed.

Specifically, the gateway 300 according to an embodiment of the present invention may be equipped with a GNSS antenna to serve as a base station in the entire system for managing location information of devices. have. In addition, the location information management unit 310 according to an embodiment of the present invention may determine reference location information indicating an accurate location of the gateway 300 above. Such reference location information may be determined by accurately measuring the location using the GNSS antenna above, or by accurately measuring the location of the gateway 300 using other positioning equipment and then inputting the location to the gateway 300. I can.

Next, the location information management unit 310 according to an embodiment of the present invention compares the location of the gateway 300 periodically measured by the GNSS antenna and the reference location information of the gateway 300 with each other. Position correction information indicating an antenna positioning error may be generated at a predetermined period. Such position correction information may follow the RTCM format described above, but is not limited thereto.

Meanwhile, the GNSS antenna may be configured as a separate device and connected to the gateway 300, but it may be possible to be embedded in the gateway 300.

Next, the position correction information transmission unit 320 according to an embodiment of the present invention may perform a function of transmitting position correction information to the device 500 through a communication channel.

Specifically, the position correction information transmission unit 320 according to an embodiment of the present invention, when the position correction information is generated by the position information management unit 310, the position correction information through the communication channel of the LPWAN Information may be transmitted to the device 500. Here, the transmission method of the position correction information is preferably a multicast method, but is not limited thereto.

Meanwhile, the above communication channel may be determined by the gateway 300 or may be determined by the management server 400.

For example, referring to FIG. 4, the gateway 300a may transmit position correction information to the devices 500a and 500c in the coverage 301a in RTCM format. At this time, the communication channel used to transmit the above position correction information is arbitrarily selected by the gateway 300a, or a channel having the best communication state (ie, not congested) is selected through monitoring of the communication channel, or This may be determined by selecting a channel that is not used (or is unlikely to be used) by the other device so as not to interfere with the communication of the other device (eg, a sensor). Here, even if the above communication channel is once determined by the gateway 300a, it can be changed by the management server 400 according to the communication state, the state of the devices 500a, 500c, etc., as will be described later. It is also possible to be determined by the management server 400 other than (300a).

For another example, referring to FIG. 4, another gateway (not shown) exists in the coverage 301a of the gateway 300a, and the above other gateway uses communication channel A to transmit position correction information. It can be assumed that there is. In this case, the gateway 300a may determine a communication channel for transmitting position correction information as B so that communication of the other gateways above is not disturbed.

On the other hand, the position correction information transmission unit 320 according to an embodiment of the present invention, when the gateway 300 receives downlink data from the management server 400, instead of the position correction information It may perform a function of transmitting the received downlink data of the device 500 to the device 500.

For example, referring to FIG. 6, the gateway 300 receives 710 downlink data from a network server (included in the management server), and transmits the downlink data to the device through a communication channel through which position correction information is transmitted. It can be assumed that the transmission should be made to 500. In this case, the position correction information transmission unit 320 may first transmit the downlink data instead of the position correction information by setting the priority of the downlink data above the position correction information. Accordingly, it is possible to prevent the location correction information from being transmitted to the device 500 during the time when the downlink data is transmitted. Even if some of the position correction information generated in this way is not transmitted, the position correction information is continuously generated at a predetermined period, so it does not significantly affect the positioning accuracy and does not interfere with other communication, so that a stable positioning service can be provided.

Next, the status information reporting unit 330 according to an embodiment of the present invention may perform a function of reporting the first status information about the gateway 300 to the management server.

Specifically, in the first state information regarding the gateway 300 according to an embodiment of the present invention, the identifier of the gateway 300, reference position information, a communication channel transmitting position correction information, and a transmission state of position correction information (Statistics on the generated position correction information and the transmitted position correction information, statistics on the position correction information not transmitted due to channel congestion or downlink data, etc.), etc. may be included, but is not limited thereto. In addition, the status information reporting unit 330 according to an embodiment of the present invention may report the first status information on the gateway 300 to the management server 400 at a predetermined period.

Next, the communication unit 340 according to an embodiment of the present invention is a function that enables data transmission and reception from/to the location information management unit 310, the position correction information transmission unit 320, and the status information report unit 330. Can be done.

Finally, the control unit 350 according to an embodiment of the present invention controls the flow of data between the location information management unit 310, the position correction information transmission unit 320, the status information report unit 330, and the communication unit 340. Can perform the function That is, the control unit 350 according to the present invention controls the data flow from/to the outside of the gateway 300 or between each component of the gateway 300, thereby transmitting the location information management unit 310, position correction information. The unit 320, the status information reporting unit 330, and the communication unit 340 may be controlled to perform their own functions, respectively.

3 is a diagram showing in detail the internal configuration of the management server 400 according to an embodiment of the present invention.

As shown in FIG. 3, the management server 400 according to an embodiment of the present invention includes a status information management unit 410, a communication channel management unit 420, a communication unit 430, and a control unit 440. Can be. According to an embodiment of the present invention, the state information management unit 410, the communication channel management unit 420, the communication unit 430, and the control unit 440 may be program modules in which at least some of them communicate with an external system. Such a program module may be included in the management server 400 in the form of an operating system, an application program module, or other program module, and may be physically stored in various known storage devices. Also, such a program module may be stored in a remote storage device capable of communicating with the management server 400. Meanwhile, such a program module includes routines, subroutines, programs, objects, components, data structures, etc. that perform specific tasks or execute specific abstract data types according to the present invention, but is not limited thereto.

On the other hand, the management server 400 has been described as above, but this description is illustrative, and at least some of the functions or components required for the management server 400 are realized within an external system (not shown) as necessary. It is obvious to those skilled in the art that it may be included or included.

First, the status information management unit 410 according to an embodiment of the present invention may perform a function of acquiring at least one of first status information about the gateway 300 and second status information about the device 500. have.

Specifically, the second state information about the device 500 according to an embodiment of the present invention includes an identifier of the device 500, a current location, a communication channel receiving position correction information, a reception state of the position correction information, etc. May be included, but is not limited thereto. In addition, the status information management unit 410 according to an embodiment of the present invention may acquire at least one of first status information about the gateway 300 and second status information about the device 500 at a predetermined period. .

Next, the communication channel management unit 420 according to an embodiment of the present invention, based on at least one of the first state information on the gateway 300 and the second state information on the device 500 ( 500) may perform a function of determining a gateway for transmitting position correction information and a communication channel of the gateway transmitting the position correction information.

In this case, the gateway for transmitting the position correction information to the device 500 and the communication channel of the gateway for transmitting the position correction information do not necessarily need to be changed, and may be maintained without change or only one of the two may be changed.

For example, referring to FIG. 4, it may be assumed that the device 500c exists in an area where the coverages 301a and 301b of the two gateways 300a and 300b partially overlap. In this case, since each of the two gateways 300a and 300b does not know each other's communication channel, a case may occur that uses the same communication channel for transmission of position correction information, and as a result, the device 500c performs position correction. You may not be able to receive information. Accordingly, the communication channel management unit 420 according to an embodiment of the present invention determines in advance which one of the two gateways 300a and 300b through which communication channel to transmit the location correction information to the device 500c, It is possible to prevent a case in which the device 500c is unable to receive the location correction information.

For another example, referring to FIG. 4, another gateway (not shown) exists in the coverage 301a of the gateway 300a, and in order to transmit the position correction information, the other gateway uses a communication channel A and a gateway (300a) may assume a case in which communication channel B is used. In this case, the communication channel management unit 420 according to an embodiment of the present invention may determine a gateway to transmit the position correction information in consideration of the distance between the gateway and the device, communication states of communication channels A and B, and the like.

On the other hand, the positioning accuracy increases as the distance between the gateway and the device is close, and the communication state of the gateway is good. Therefore, the communication channel management unit 420 according to an embodiment of the present invention, in determining a gateway for transmitting the location correction information to the device 500, a weight between the gateway and the device and the communication state of the gateway. By assigning and determining the score of each gateway based on the weight, it can also be used to determine a gateway that transmits location correction information to the device.
