Description

{Method and Apparatus for providing and monitoring real time space information}

The present invention relates to a method and apparatus for tracking real-time spatial information provision and use, and it is possible to quickly provide and utilize a spatial information page requested by a user among a vast amount of spatial information, while tracking the usage form of spatial information by each user. It relates to a technology that monitors and calculates utilization statistics to enable more efficient use of spatial information.

With the recent development of information technology, the life cycle of software such as hardware and GIS is getting shorter. Accordingly, spatial information should be constructed so that it can be used regardless of the type of GIS engine. And there are many difficulties in using it.

Meanwhile, with the National Spatial Data Infrastructure (NSD) construction project, the amount of domestic spatial information continues to increase, creating new added value. Viewers who want an easy spatial information service rather than software requiring complex functions The market potential is growing. While the provision of remote civil service and administrative services using spatial information such as topographic maps, subject maps, and cadastral maps is required, it is also necessary to provide services of spatial information verified and refined by digital map producers through distribution agencies.

However, spatial information based on a distributed environment is not only vast, but also very complex, and is used in different hardware or software environments, so it is difficult to provide or utilize information in a standardized form.

In addition, in the provision and utilization of spatial information, in a network system such as a web server or a wap server, if a large number of users suddenly run into a connection within a short period of time, connection processing is delayed or even the system is down. A problem arises.

In order to solve this problem, products such as solutions or switches that cope with traffic congestion allow the administrator to set the threshold directly, but in this case, there is a difficulty in calculating the actual system threshold, and also real-time application is not possible or incorrect. In case of calculation and setting, the whole system is adversely affected.

On the other hand, when providing and utilizing spatial information, places that do not use traffic control products are solving the problem by adding servers to handle users' access. However, although expanding the server can accommodate the user's request, there is a limit to the processing power of equipment that uses limited resources such as DB (Database) or WAS (Web Application Server), so the user's request exceeds a certain level. If this happens, there is a problem that it can no longer be processed.

In addition, if the user's request is above a certain level, it affects all services related to limited resources other than the processing of the request, making it impossible to provide the entire service smoothly. There is this.

In order to solve such difficulties, Korean Patent Application Laid-Open No. 2016-0073893 measures the service quality of the user accessing the service server, determines whether to adjust the number of allowed entries to the service server according to the measured service quality, and adjusts the allowed number of entries. Disclosed are a user service quality-based real-time allowed entry management apparatus and method for controlling a user's access to a service server by adjusting the allowed entry number of a service server according to information.

Although the load on the network system is different for each page provided by the network system, in the conventional system to which the automatic access sequence control function is applied, it does not consider the characteristics of each page of spatial information, and simply allows sequential access according to the waiting sequence. Even for requests that place a light load on the system, there was a problem that a lot of waiting time was required to deliver the page.

In addition, most of the geographic information-related data being developed so far is specialized to operate only on the GIS engine or geographic information service engine of a specific provider. is required Therefore, there is a need for a technology that can be used regardless of the type of geographic information service engine, and thus can receive spatial information quickly and freely utilize it.

1 is a block diagram illustrating an apparatus for providing and tracking real-time spatial information according to an embodiment of the present invention.

Referring to FIG. 1 , the spatial information service engine 100 according to the present invention may manage a session connection between the user terminals 200a, 200b, 200c, ..., 200n and the spatial information system 300 .

The spatial information service engine 100 may be connected to the user terminals 200a, 200b, 200c, ..., 200n and the geographic information system 300 through the communication network 10 to exchange various types of information and data.

The communication network 10 includes various data including a local area network (LAN), a wide area network (WAN), the Internet, 3G, 4G, 5G mobile communication networks, Wi-Fi, or Long Term Evolution (LTE). It may include a communication network, and may be applied as long as it is a communication network capable of transmitting and receiving data regardless of wired or wireless.

The user terminals 200a, 200b, 200c, ..., 200n are information communication terminals used to use the services provided by the geographic information system 300 , and include computers, notebook computers, smartphones, tablet PCs, and PDA's. Any type of terminal will be applicable as long as it is equipped with a memory means such as (Personal Digital Assistant) or a Web Pad, and is equipped with a microprocessor and has arithmetic capability.

The geographic information system 300 may provide a page of geographic information stored therein at the request of the user terminals 200a, 200b, 200c, ..., 200n. Here, the page may be a web page, which is a file in which content and specifications for the location of images, sounds, videos or other multimedia files are annotated in Hypertext Generation Language (HTML).

The geographic information system 300 may perform a function of providing a page of corresponding geographic information in response to a specific geographic information request from the user terminals 200a, 200b, 200c, ..., 200n, and according to the needs of the invention, One or more web applications may be applied to the server device in a built-up form.

The spatial information service engine 100 checks whether the user terminals 200a, 200b, 200c, ..., 200n are accessible to the geographic information system 300 registered as a management target, and determines whether the user terminals 200a, 200b, 200c, ..., 200n) and the geographic information system 300 may manage a session connection.

The spatial information service engine 100 may determine in real time whether to apply the automatic access sequence control function to each page of spatial information provided by the geographic information system 300 .

i) The spatial information service engine 100 registers a user terminal that has made an access request to the access waiting queue for the page for which the automatic access sequence control function application is turned on, and delivers the waiting page ii) In addition, the spatial information service engine 100 directly sends the user terminal requesting access to the geographic information system 300 for the page to which the automatic access sequence control function application is turned off. can be connected.

2 is a detailed configuration diagram of an apparatus for providing and tracking real-time spatial information according to an embodiment of the present invention.

The spatial information service engine 100 may include a policy management unit 110 , a page delivery time measurement unit 130 , a policy application unit 150 , and a connection management unit 170 .

The policy management unit 110 may be provided with a policy in which an automatic access sequence control application standard is set for each page of spatial information provided by the spatial information system 300 . For example, if the pages provided by the target network system 300 have pages A, B, C, and D, as illustrated in Table 1 below, automatic access sequence control application standard for each page of A, B, C, and D spatial information This can be set.

Page Automatic connection sequence control application standard time A T1 B T2 C Not applicable D T1

Here, page A and page D indicate that the automatic access sequence control function is applied when the real-time average page delivery time exceeds the application reference time 'T1'. In addition, page B indicates that the automatic access sequence control function is applied when the real-time average page delivery time exceeds the application reference time 'T2', and page C indicates that the automatic access sequence control function is not applied.

The automatic access sequence control application reference time may be set for all pages or only for some pages according to the necessity of the invention. In addition, the reference time for applying the automatic access sequence control may be set to be the same for each page, the same only partially, or all differently.

Here, the page delivery time (Td) is the difference between the page delivery time (T _RES ) of the geographic information system 300 from the page request time (T _REQ ) of the user terminals 200a, 200b, 200c, ..., 200n (T _RES - T _REQ ).

The real-time average page delivery time T _AV may be obtained for each page of each spatial information in real time in a predetermined time unit. For example, as illustrated in Table 1 above, if the real-time average page delivery time is obtained in units of 1 minute in a state in which the policy is set, the real-time average page delivery time ( _TAV ) for pages A, B, and D every minute can be obtained Since the automatic access sequence control function is not applied to page C, it will not be necessary to calculate the real-time average page delivery time ( _TAV ).

Meanwhile, the reference time for applying automatic access sequence control may be obtained by multiplying the average page delivery time obtained for each page during the predetermined learning period by a predetermined ratio.

For example, assuming that the average page delivery time of page A is T' _AV and the predetermined ratio (R) is 130%, for a predetermined learning period after the geographic information system 300 is built and started operation, The standard time for automatic connection sequence control application can be set as “1.3× _T'AV ”.

Of course, whenever there is a need or change in the page content provided by the geographic information system 300 , the average page delivery time ( _T'AV ) may be obtained again, and the automatic access sequence control application reference time may be changed based on this. In this case, the policy provided by the spatial information system 300 may be a predetermined ratio R for each page of spatial information as illustrated in Table 2 below.

Page Predetermined Ratio (R) A 130% B 120% C 130% D 110%

For page A and page C, the time obtained by multiplying the average page delivery time ( _T'AV ) respectively obtained during the predetermined learning period by 1.3 may be determined as the automatic access sequence control application reference time. That is, even if the predetermined ratio is the same for page A and page C, if the average page delivery time (T' _AV ) obtained during the learning time is different from each other, the automatic access sequence control application reference time may also be different.

Similarly, for page B and page D, the time obtained by multiplying the average page delivery time (T' _AV ) obtained respectively during the predetermined learning period by 1.2 and 1.1, respectively, may be determined as the reference time for applying the automatic access sequence control.

The policy management unit 110 may receive a policy in which the automatic access sequence control application standard is set from an operator who operates the spatial information service engine 100 or an operator who operates the spatial information system 300 .

The page delivery time measurement unit 130 may measure a real-time average page delivery time for each page of spatial information provided by the spatial information system 300 . As described above, the average page delivery time for each page of spatial information may be measured in real time in a preset time unit.

Meanwhile, for pages to which automatic access sequence control is applied, the average page delivery time can be measured for user terminals registered in the access waiting queue. For example, the user terminals 200a, 200b, 200c, ..., 200n are registered in the access waiting queue, receive the waiting page, and then retry access to the spatial information system 300 after a preset time to transmit the page request again. can For pages to which automatic access sequence control is applied, the page delivery time measurement unit 130 measures the average page delivery time in the case of page delivery of the geographic information system 300 according to the page request of the user terminal that has retryed access can do.

To this end, the standby page delivered to the user terminals 200a, 200b, 200c, ..., 200n may include a script written to request access again after a preset time. According to the needs of the present invention, a script written for the user terminal to request access again at a preset time interval may be included in the standby page.

The policy application unit 150 may automatically turn on the automatic access sequence control function for pages provided by the spatial information system 300 for which the real-time average page delivery time is equal to or greater than the automatic access sequence control application standard. . In addition, the policy application unit 150 may automatically turn off the automatic access sequence control function for pages whose real-time average page delivery time is less than the automatic access sequence control application criterion among the pages on which the automatic access sequence control function is turned on.

The automatic access sequence control application standard may be predetermined for each page of spatial information according to a provided policy. As described above, the reference time for applying automatic access sequence control for each page of spatial information is set immediately, or it is determined as the reference delivery time obtained by multiplying the average page delivery time obtained for a predetermined period by a preset ratio for each page of spatial information. can

When the access management unit 170 receives a page request from the spatial information system 300 from the user terminals 200a, 200b, 200c, ..., 200n, whether the automatic access sequence control function of the corresponding page is On can be treated differently depending on

Upon receiving a request for a page on which the automatic access sequence control function is turned on from the user terminals 200a, 200b, 200c, ..., 200n, the access management unit 170 controls the corresponding user terminals 200a, 200b, 200c, ..., 200n), the user terminals 200a, 200b, 200c, ..., 200n may be registered in the connection waiting queue corresponding to the requested page, and the waiting page may be delivered.

The access management unit 170 maintains the number of concurrently connected sessions at the time when the automatic access sequence control function is turned on or less, and maintains the number of sessions connected to the page on which the automatic access sequence control function is turned on. 200a, 200b, 200c, ..., 200n) can be sequentially connected.

For example, assuming that the number of sessions connected to page A is 15 when the automatic access sequence control function is turned on, the spatial information system 300 and user terminals 200a, 200b, 200c, ..., 200n for page A The user terminals 200a, 200b, 200c, ..., 200n may be sequentially connected to page A while maintaining the number of session connections of 15 or less.

On the other hand, when receiving a request for a page in which the automatic access sequence control function is turned off from the user terminals 200a, 200b, 200c, ..., 200n, the access management unit 170 is the corresponding user terminals 200a, 200b, 200c, ..., 200n) and the spatial information system 300 may connect a session and transmit the corresponding page to the spatial information system 300 .

3 is a flowchart illustrating an on-off operation of an automatic access sequence control function of a method for providing and tracking real-time spatial information according to an embodiment of the present invention.

1 to 3 , first, the spatial information service engine 100 may be provided with a policy in which an automatic access sequence control application standard is set for each page of spatial information ( S300 ). In step S300 , the policy may be received from the geographic information system 300 or provided from the operator server (not shown) of the spatial information service engine 100 according to the needs of the invention.

Thereafter, the spatial information service engine 100 measures the page request time of the spatial information transmitted from the user terminals 200a, 200b, 200c, ..., 200n and the page transmission time of the spatial information from the spatial information system 300 while measuring the A real-time average page delivery time may be measured for each page of spatial information (S310).

Then, the spatial information service engine 100, among the pages provided by the spatial information system 300, if there is a page whose real-time average page delivery time ( _TAV ) is equal to or greater than the automatic access sequence control application standard (S320-Y), it is added to the page. It is possible to turn on (ON) the automatic connection sequence control function for the (S330).

In addition, the spatial information service engine 100 can sequentially connect the user terminals 200a, 200b, 200c, ..., 200n by applying the automatic access sequence control function to the page on which the automatic access sequence control function is turned on ( S340).

Next, if there is a page whose real-time average page delivery time (T _AV ) is less than the automatic access sequence control application standard among the pages on which the automatic access sequence control function is turned on (S350-Y), the spatial information service engine 100 responds to the corresponding page. It is possible to turn off the automatic connection sequence control function (S360).

4 is a flowchart of a method for providing and tracking real-time spatial information according to an embodiment of the present invention.

1, 2 and 4, when a page request for specific spatial information is transmitted from the user terminal (S405), the spatial information service engine 100 performs an automatic access sequence control function for the requested spatial information page. It is checked whether this is on (S410).

When the automatic access sequence control function is turned off (S410-N), the spatial information service engine 100 connects a session between the user terminal and the spatial information system 300 and transfers the requested spatial information page to the spatial information system 300 ) to (S415).

Then, the spatial information service engine 100 receives the spatial information page from the spatial information system 300 (S455), transmits it to the user terminal (S460), and displays the spatial information page on the user terminal so that the user can use it. becomes (S465).

At this time, the spatial information service engine 100 generates a log matching the requested spatial information page (S470), mixes the received spatial information to process the log (S475), and then processes the processed log (S475). The log data (S475) is transferred back to the spatial information system 300, so that the operator or manager of the spatial information system 300 tracks and monitors the utilization aspect of the spatial information (S480).

Here, the log matching the requested spatial information page may include user information of the user terminal, an IP address, an area of use, and the like. In addition, the received spatial information to be mixed may include a tagging value with spatial information for each region and spatial information for each type.

The geospatial information by region may be geospatial information about local governments in large areas such as Seoul, Daejeon, Daegu, Busan, and Gwangju, or geospatial information about each city, county, gu, or each county, eup, myeon, and ri, and the spatial information for each type is It can be spatial information related to underground facilities (water supply pipelines, sewage pipelines, buried high-voltage lines, etc.), land facilities (buildings, houses, forests, farmland, roads, etc.) or marine-related (submarine topography, coastlines, etc.).

The spatial information for each type may include various types of survey information, aerial photography information, image processing information, image mapping information, numerical map information, and MMS (Mobile Mapping System) information among underground facilities, land facilities, or marine related spatial information.

When the processed log is input to the spatial information system 300 in this way, the operator or manager monitors spatial information for each region and type of spatial information provided to each user terminal in real time or periodically using the processed log information. Thus, the system can be operated to provide more efficient spatial information by calculating the statistics.

The monitoring of the spatial information may be displayed so that it is convenient to check the indicators for the use of spatial information through the display of a dashboard or a screen for each detailed analysis indicator in the terminal of the operator or manager.

For example, when the frequency of use of users residing in Gangwon-do increases during a predetermined period and page requests for subsea topography related spatial information increase, the spatial information system 300 prioritizes the provision of subsea topography related spatial information in Gangwon-do. By setting this setting, it will be possible to provide more rapid and efficient spatial information by lowering the rate at which the user terminal is registered in the connection waiting queue.

That is, the spatial information system 300 inputs a policy for providing spatial information applied after calculating the above statistics into the spatial information service engine 100 in advance (S400), and a page request for spatial information with priority is inputted. When it is (S405), the page request of the user terminal is not registered in the access waiting queue but is directly input to the spatial information system 300 (S415), and then the page for the corresponding spatial information is delivered to the user terminal (S460) to prompt spatial information It can be operated so that it can be provided.

On the other hand, if the automatic access sequence control function is turned on (S410-Y), the spatial information service engine 100 registers the user terminal in the access waiting queue (S420), and transmits the waiting page to the user terminal (S425). Next, when a preset time has elapsed in the waiting page, the user terminal attempts to access the spatial information system 300 again (S430). Then, the user terminal retransmits a request for a page of spatial information to the spatial information service engine 100 (S435).

When the spatial information service engine 100 receives a request for a page of spatial information from the user terminal again, it checks whether access is possible (S440). If the user terminal cannot access (S440-N), the spatial information service engine 100 may deliver the standby page back to the user terminal (S450). Thereafter, when the preset time elapses as described above, the user terminal retryes access to the spatial information system 300 (S430).

On the other hand, if the user terminal is accessible (S440-Y), the spatial information service engine 100 connects a session between the user terminal and the spatial information system 300 and delivers the requested spatial information page to the spatial information system 300 . do (S445). Then, the spatial information service engine 100 receives a page of spatial information corresponding thereto from the spatial information system 300 (S455) and transmits it to the user terminal 200a (S460).

Embodiments of the present invention may include a computer-readable medium including program instructions for performing various computer-implemented operations. This medium may record a program for executing the method described above, and may include program instructions, data files, data structures, etc. alone or in combination.
