Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote terminal having a data backup function,

The present invention relates to a remote terminal having a data backup function and a method thereof, and more particularly, to a remote terminal having a data backup function for backing up data on a transmission lost time period in which data is not received from a remote terminal in a server, And a method thereof.

In general, the remote terminal obtains sensing data such as pressure, flow rate, temperature, and the like, and transmits sensing data to a monitoring server connected to the network. At this time, the transmission is performed at intervals of several seconds to several minutes at the request of the monitoring server. Since the remote terminal transmits data to the monitoring server through the network, data transmission may fail if a network failure occurs inevitably. In addition, the surveillance server may not receive data from the remote terminal due to its own problems. When a data loss interval occurs in the monitoring server according to such a situation, data of an accumulated value such as a flow rate can be restored by interpolation even if data is partially missing in the middle of the attribute data. However, Or a variation thereof may cause various problems due to data omission during a certain period of time.

On the other hand, in storing remote sensing data as time series data, a large memory capacity is required, but a limited capacity is used due to cost and physical factors. In order to solve the limitation of the memory capacity, there is a method of storing time series data based on a time sliding window. For example, if the size of the time sliding window is set to 1 hour, data within 1 hour is stored and data after 1 hour is sequentially deleted. As a result, only data from 1 hour before the current time is stored. It is necessary to take time sliding window value of time series data to a large value because the data communication disconnection with the remote place is recovered in a short time but sometimes it is not. However, as pointed out, it is difficult to unconditionally increase it because of the limitation of memory capacity. As a result, there is a need for a method for effectively controlling the memory capacity occupied by the time series data.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

1 is a block diagram schematically illustrating a configuration of a remote terminal having a plurality of data backup functions connected to a plurality of servers according to an embodiment of the present invention

As shown in FIG. 1, a remote terminal 200 having a data backup function according to an embodiment of the present invention communicates with a plurality of servers 100 through a communication network. At this time, the remote terminal 200 having the data backup function and the server 100 may be configured as one to one, one to many, many to many, or many to many.

In this configuration, when the server 100 requests data to the remote terminal 200, the remote terminal 200 having the data backup function can transmit the requested data to the server 100 through the communication network. Here, the data request is classified into the periodic request and the interval request. The periodic request is a data request that is periodically performed at regular intervals by the server 100 to acquire the data acquired by the remote terminal 200 having the data backup function. The interval request is a data request for a lost interval if data is lost due to an external factor such as an error of the server 100 or a communication network or an internal factor and the data transmission fails due to a regular request.

2 is a block diagram illustrating a detailed configuration of a remote terminal having a data backup function according to an embodiment of the present invention.

2, the remote terminal 200 having a data backup function includes a sensor unit 210, a data management unit 230, a data storage unit 250, a request processing unit 270, and a communication unit 290 .

The sensor unit 210 may include at least one sensor and may acquire data at predetermined time intervals through the corresponding sensor. For example, the sensor unit 210 may acquire data such as pressure, temperature, wind direction, and wind speed.

The data management unit 230 temporarily stores the data acquired by the sensor unit 210, and can manage the data to be backed up and stored as necessary. That is, the data management unit 230 may temporarily store the data in the first storage unit 251. If the data management unit 230 determines that the data request has not been received within the time limit, the data management unit 230 stores the data in the second storage unit 253. Here, the time limit is a time period when a data request is not received from the monitoring server 100 because the period of the periodic request exceeds the period of the periodic request. As a criterion for backing up the data acquired by the sensor unit 210, And the time factor may be set in consideration of the capacity of the first storage unit 251 and the stability of the backup. For example, it is desirable that the time limit is at least two times greater than the period of the regular request, so the time factor may be two or more. At this time, the data management unit 230 may store, in the second storage unit 253, data not transmitted to the server among the data of the first storage unit 251 as backup data.

Also, the data management unit 230 can set the acquisition time and the data storage lifetime according to the data acquisition interval. For example, when the data acquisition is performed in units of seconds, the data management unit 230 manages the data as a key representing the data acquisition time in year / month / day / hour / minute, and sets the storage life to several hours have. In addition, when data acquisition is performed in units of minutes, the data management unit 230 manages the data as a key indicating the data acquisition time at year / month / day / hour, and can set the storage life to several days. Here, the data management unit 230 may set the data lifetime of the second storage unit 253 to be longer than the data lifetime of the first storage unit 251.

The data storage unit 250 includes a first storage unit 251 and a second storage unit 253. The first storage unit 251 of the data storage unit 250 temporarily stores the acquired data, and the second storage unit 253 may store the data for backup. At this time, the first storage unit 251 and the second storage unit 253 may store data in the form of a time sliding window according to the data lifetime setting. Here, the first storage unit 251 and the second storage unit 253 may be set for each data type acquired by the sensor unit 210.

The request processing unit 270 may process the data of any one of the first storage unit 251 and the second storage unit 253 to the monitoring server according to the request received from the monitoring server. That is, the request processing unit 270 may transmit data of the first storage unit 251 when the data request received from the monitoring server is a regular request. If the data request is a period request, the request processing unit 270 determines whether the period request is within the time limit. If the request is within the time limit, the request processing unit 270 transmits the data of the first storage unit 251, Data of the second storage unit 253 can be transmitted. In this case, the interval request may be transmitted to the first storage unit 251 because the surveillance server is performed for the data loss interval, but before the data backup is started within the limit time.

The request processing unit 270 may calculate a periodic request period of data for setting a time limit. That is, the request processing unit 270 may calculate the regular request period by averaging the request time of the data periodically received from the monitoring server 100. [ At this time, when the remote terminal 200 is interworked with the plurality of the monitoring servers 100, the regular request period of each of the monitoring servers 100 may be averaged and calculated as a periodic request period for setting the time limit.

In addition, the request processing unit 270 may adjust the time factor according to whether or not the interval request is received within the time limit. For example, when the interval request is made within the time limit, the request processing unit 270 may reduce the time count so as to shorten the time limit so that the backup can be stably performed. In addition, when the interval request is made over the time limit, the request processing unit 270 may increase the time count so as to lengthen the time limit to prevent unnecessary backups.

In addition, when the request processing unit 270 transmits the data of the second storage unit 253 to the monitoring server 100, the life of the backup data can be shortened. In addition, when the data of the second storage unit 253 is transmitted to the monitoring server, the request processing unit 270 may shorten the data life so as to increase the storage efficiency of the second storage unit 253. [ That is, when the backup data is transmitted to the monitoring server 100, the monitoring server 100 can recover the data loss interval, so that the request processing unit 270 can quickly delete the data having low storage necessity, The life of the data can be shortened in order to secure the capacity of the memory cells 253 and 253. At this time, when the remote terminal 200 is interlocked with the plurality of the monitoring servers 100, since the disconnection interval data transmitted to one of the monitoring servers 100 can be requested from the other monitoring servers 100, 100), the life of the data can be shortened. For example, the request processing unit can halve the lifetime of each data request from one monitoring server.

The communication unit 290 can communicate with the monitoring server 100 through a wired / wireless communication network. Here, the communication between the communication unit 290 and the monitoring server 100 may be performed in XML or SQL format. The communication unit 290 may communicate with the monitoring server 100 through a private network (VPN) to enhance the security of the XML or SQL method.

With this configuration, the remote terminal 200 having the data backup function according to the embodiment of the present invention can recover the data in the lost section, thereby improving the stability and reliability of data storage, The limited capacity can be efficiently used by controlling according to the situation.

Hereinafter, a data backup method according to an embodiment of the present invention will be described in detail with reference to FIGS. 3 to 5. FIG.

3 is a flowchart illustrating a data backup method according to an embodiment of the present invention. 4 is a flowchart showing a data storing method of FIG. 5 is a flowchart showing a data request processing method of FIG.

The data backup method 300 includes a step S301 of calculating a data periodicity request period, a step S302 of storing data, and a step S303 of processing a data request.

More specifically, first, a data period request period can be calculated to set a time limit (step S301). As described above, the backup start of data is determined as the time limit, and the periodic request period can be calculated as a criterion for determining the time limit. For example, when the request time of data periodically received from the monitoring server 100 is averaged or when the remote terminal 200 interlocks with a plurality of the monitoring servers 100, As a periodic request period for setting the time limit.

Next, the data acquired by the remote terminal 200 may be temporarily stored, and may be backed up and stored as needed (step S302). At this time, the acquisition time and the data storage life according to the data acquisition interval can be set and stored. For example, the data acquired every second is stored together with the key representing the data acquisition time in year / month / day / hour / minute and the storage life of several hours, / Day / hour, and a storage life of several days.

Next, in response to the data request from the monitoring server 100, the temporary storage data or the backup data may be transmitted to the monitoring server (step S303). At this time, if the data request received from the monitoring server 100 is a periodic request, the temporary storage data can be transmitted. In addition, if the data request is a period request, the temporary storage data may be transmitted if the interval request is within the time limit, or the backup data may be transmitted if the interval request is not within the time limit. Here, the interval request is transmitted to the monitoring server during the data loss interval, but since the data backup is not started within the limit time, the temporary storage data can be transmitted in this case.

The data storage step of step S302 of FIG. 3 will be described in more detail with reference to FIG.

The data storage method 400 includes a step S401 of obtaining data, a step S402 of storing data in the first storage unit, a step S403 of determining whether a data request is received within a time limit, (Step S404).

More specifically, data can be acquired at predetermined time intervals through the corresponding sensor (step S401).

Next, the acquired data may be stored in the first storage unit 251 of the data storage unit 250 (step S402). At this time, the first storage unit 251 stores temporary data, and stores data in a time sliding window method.

Next, it is determined whether or not the data request is received within the time limit (step S403). If it is determined that the data request is received within the time limit, the process returns to step S401 and data acquisition and storage in steps S401 and S402 can be repeatedly performed .

If it is determined in step S403 that the data request is not received within the time limit, the backup data may be stored in the second storage unit 253 (step S404). After the start of the backup data, the process returns to step S401 to repeatedly perform the data acquisition and data storage in steps S401 to S403.

The data request processing step of step S303 of FIG. 3 will be described in more detail with reference to FIG.

The data request processing method 500 includes a step S501 of receiving a data request, a step S502 of determining whether it is a periodical request, a step of transmitting temporarily stored data S503, (S504), and transmitting the temporary storage data or the backup data to the monitoring server according to the determination result (S505 to S509).

First, a data request can be received from the monitoring server 100 (step S501). At this time, the data request can be received periodically or temporarily.

Next, it is determined whether the data request received from the monitoring server 100 is a regular request (step S502). If it is determined that the data request is a regular request, data temporarily stored in the first storage unit 251 may be transmitted to the monitoring server Step S503).

If it is determined in step S502 that the data request received from the monitoring server is not a regular request, that is, if the received data request is a section request, it is determined whether the received section request is received within a time limit (step S504) If it is determined that the interval request is received within the time limit, the temporary data stored in the first storage unit 251 may be transmitted to the monitoring server 100 (step S505). At this time, the interval request is made for the data loss interval of the monitoring server 100, but since the data backup is not started within the time limit, the temporary data can be transmitted in this case.

Next, the time count can be reduced to shorten the backup start time (step S506). That is, since there is an interval data request for the lost section before the backup, shortening the backup start can improve the stability of the backup. Therefore, the time factor can be reduced to shorten the time limit. After the time count is decreased as described above, the process returns to step S501 to wait for the next data request.

If it is determined in step S504 that the interval request has not been received within the time limit, the backup data stored in the second storage unit may be transmitted to the monitoring server 100 (step S507).

Next, the time factor may be increased to increase the backup time (step S508). In other words, if the interval request is made beyond the time limit, it is possible to prevent unnecessary backups from extending the backup start. Therefore, the time factor can be increased to increase the time limit. Next, the service life of the backup data transmitted to the monitoring server 100 can be shortened (step S509). That is, when the backup data is transmitted to the monitoring server 100, the monitoring server 100 can recover the data loss period, thereby shortening the data life to secure the backup capacity by deleting the data with low storage necessity early . In this case, when the remote terminal 200 is interlocked with the plurality of the monitoring servers 100, since the disconnection interval data transmitted to one of the monitoring servers 100 can be requested from the other monitoring servers 100, 100), the life of the data can be shortened. For example, the request processing unit 270 may halve the lifetime of each data request from one monitoring server 100. [

After the lifetime of the backup data is shortened as described above, the process returns to step S501 to wait for the next data request.

According to this method, the backup data storing method according to the embodiment of the present invention can recover the data in the disappearance interval, thereby improving the stability and reliability of data storage, controlling the memory storage capacity according to the situation, Can be efficiently used.

Such methods may be implemented by a remote terminal 200 as shown in FIG. 1, and in particular as a software program that performs these steps, in which case such programs may be stored in a computer- Or by a computer data signal coupled with a carrier wave in a transmission medium or a communication network.

At this time, the computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. For example, ROM, RAM, CD-ROM, DVD-ROM, DVD- , A floppy disk, a hard disk, an optical data storage device, or the like.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
