It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout the specification and claims. The description will be omitted.

1 is a block diagram schematically illustrating an entire system for collecting data of a plurality of devices using a mobile communication network according to an embodiment of the present invention.

Referring to FIG. 1, the overall system according to the present embodiment includes a plurality of management apparatuses 10-1, 10-2, ..., 10-n, collectively referred to as 10, a communication network 30, 50 and a monitoring system 70.

The management device 10 may be various input / output devices such as sensors. For example, assuming that the system according to the present embodiment is applied to a water quality management system, the management device 10 is installed in each block (a sensing point to be managed) And the like may be the management equipment 10. Data collected from the management device 10 may be divided into report data for monitoring the sensing information and the like and alarms and event signals. For example, an event signal may include an error signal.

The data collecting device 50 collects the reporting data and the event / alarm data from the management equipment 10 and provides the collected data to the monitoring system 70 which is an upper system. For example, the reporting data is stored in the database (DB, 72) of the monitoring system 70 and an alarm / event signal is provided to the management / operation PC 74 to enable the administrator to check this in real time. Of course, it is natural that the administrator can check the data stored in the database 72 at any time using the management / operation PC 74. Accordingly, the manager using the present system can monitor the management equipment 10 in real time through the monitoring system 70. [

In particular, the management device 10 according to the present embodiment transmits and receives data through the mobile communication network 34. [ As a result, the communication line is used only when data is actually transmitted and received. Therefore, the efficiency of line utilization can be improved compared with the conventional method using a dedicated line.

The data collection device 50 collects data from the management devices 10 through the mobile communication network 34 and the Internet network 32. For example, the data collection device 50 may be implemented as a gateway . Particularly, the data collecting apparatus 50 according to the present embodiment is capable of collecting data at a time when each management equipment 10 transmits report data in order to reduce processing load in case data from each management equipment 10 is simultaneously pushed And provides the data transmission schedule to each management equipment 10. The management server 10 is connected to the management apparatus 10 via a network. In other words, the management equipment 10 transmits report data at a time allocated to each of them according to a set data transmission schedule. According to an example, the alarm / event signal other than the report data may be transmitted in real time regardless of the transmission schedule. The data transmission schedule and reporting data will be described in detail later.

Hereinafter, the function of the data collecting apparatus 50 will be described in detail.

FIG. 2 is a block diagram showing the configuration of a data collecting apparatus 50 according to an embodiment of the present invention, and FIG. 3 is a block diagram showing a format of report data according to an embodiment of the present invention.

2, the data collecting apparatus 50 includes a communication unit 210, a storage unit 230, and a control unit 250. The storage unit 230 includes a first storage unit 232 And a second storage unit 234. The control unit 250 may include a schedule management unit 252 and a data management unit 254. [

Communication through the communication network 30 such as the Internet network 32 and the mobile communication network 34 will be apparent to those skilled in the art. Therefore, the communication unit 210 is a communication unit for transmitting / Will not be described in detail. The data collecting apparatus 50 may communicate with the monitoring system 70 through a network (for example, LAN, Ethernet, etc.) And performs communication with the monitoring system 70.

The control unit 250 generates a data transmission schedule containing information on when the management equipment 10 transmits data, and classifies the report data received from the management equipment 10 according to a specific criterion.

The schedule management unit 252 of the control unit 250 generates and manages a data transmission schedule, and according to an example, generates a data transmission schedule according to a specific criterion. For example, a data transmission schedule can be created corresponding to the priority set in each management equipment 10, and the priority can be set in advance by the administrator or can be set according to the reporting data transmission history of the management equipment 10 May be set. As an easy example, it is preferable to collect frequent report data as the amount of change in the sensing information according to the report data previously received from the management equipment 10 increases. In this case, the priority of the management equipment 10 is high Can be set. Of course, this is only an example, and it is natural that various criteria for determining the priority can be used. Accordingly, by setting the transmission schedule in the data collection device 50, it is possible to manage the number of times of sensing and transmission time of each management equipment 10 at the center.

As another criterion for setting a data transmission schedule in addition to the above-described priority order, the amount of report data transmitted by each management equipment 10 may be used. For example, by using the data amount of the average report data of each of the management equipments 10 to be collected, a schedule can be created so that the report data having a high data amount is not received at the same time. As an easy example, if the average data amount of the management equipment 1 to 3 is 100 bytes and the average data amount of the management equipment 4 to the management equipment 6 is 50 bytes, each of the management equipment 1 to management equipment 3 is managed by the management equipment 4 to management equipment The data transmission schedule may be set so as to transmit the report data at the same time or at a time similar to any one of the management apparatuses 1 and 6 (see management equipment 2 and 4 in FIG. 5).

According to another example, each management device 10 generates and provides a sensing schedule for the time information for generating the sensing data for a day to the data collection device 50, and the data collection device 50 The data transmission schedule can be generated using the sensing schedule. For example, a data transmission schedule is generated so that more transmission time is allocated to management equipment that frequently generates sensing data.

According to another embodiment, the schedule management unit 252 can generate a plurality of data transmission schedules. A priority data transmission schedule is generated as a first schedule and provided to each management equipment 10, and a sub schedule is generated if necessary, and the management schedule is provided to the management equipment 10 again. As an easy example, the schedule management unit 252 analyzes the report data received for a predetermined time (for example, one hour) after transmitting the data transmission schedule according to the first schedule to the management equipment 10, Efficiency can be measured, and sub-schedules which are different schedules can be generated and provided when the measured efficiency is equal to or less than a predetermined standard. Therefore, the management apparatuses 10 transmit the report data according to the sub-schedules thereafter. Of course, efficiency may also be determined for the sub-schedules, and according to one example, the management devices 10 may send the report data to another schedule (or previous schedule) if the efficiency is less.

The criterion of efficiency mentioned above may be how efficient the network is used, how accurate and fast the data is received, and so on.

Also, the sub-schedule is not provided only when necessary, but may be provided to the management equipment 10 in advance so that each management equipment 10 may store the corresponding sub-schedule. So that the management equipment 10 can use the sub-schedule when it is determined that the efficiency according to the sub-schedule is low.

According to another embodiment using a sub-schedule, a sub-schedule is used in case a failure occurs in any management equipment 10. In other words, if the management device A fails, each management device transmits the reporting data to the corresponding sub-schedule A. According to an example, the number of sub-schedules may be as many as the number of management equipment 10, or the management equipment 10 may be divided into groups and sub-schedules for each group may be used.

If a change in the data transmission schedule is required, the schedule management unit 252 changes the schedule and provides change schedule information only to the management equipment 10 related to the changed schedule. For example, if the urgent acquisition of the sensing information of the management apparatus 10 is required according to the alarm or event information received from the arbitrary management apparatus 10, the data transmission schedule may be adjusted accordingly, And transmits the changed contents to the related management equipment 10 through a message transmission service provided by the mobile communication network 34 such as SMS (short message service). The management device 10 receiving the SMS receives characters of the SMS and recognizes the changed schedule, and transmits the report data to the data collection device 50 according to the changed schedule.

In summary, the schedule management unit 252 sets a data transmission schedule for a reporting data transmission time point of each management equipment 10 according to a preset standard, and adjusts a data transmission schedule when a schedule change is required to provide related information And only a part thereof is changed, the changed contents are provided to the related management equipment 10 only by using the message transmission service provided in the mobile communication network 34. [

The data management unit 254 functions to sort the report data collected from the management equipment 10 according to a predetermined criterion. The classification criteria of the report data uses the sensing time of the sensing information according to the report data. That is, report data based on sensing information measured at the same or a similar level or more are grouped and processed, and the report data is classified according to the sensing time zone.

The reason for this is that management equipment 10 senses the sensing information and transmits the report data to the data collection device 50 immediately instead of sending the report data to the data collection device 50 , The data collection device 50 must classify the report data according to the sensing time (i.e., measurement time) for accurate monitoring.

Therefore, the management equipment 10 should generate the report data so as to include information on the measurement time.

3, the report data includes a measurement time field 310 for measurement time, an identification information field 320 for identifying the management device 10, and a measurement value field 330 in which measurement values are recorded do.

Also, as shown in the figure, according to an example, the report data may further include a transmission time field 300 having information on a transmission time of transmitting the report data. The transmission time information according to the transmission time field 300 may be used for creating or modifying a data transmission schedule. For example, although the management equipment 10 transmits the report data at the correct time according to the data transmission schedule, the report data is not transmitted to the mobile communication network 34 due to some problem, such as the occurrence of a problem in the communication network 30, This is because the data collecting apparatus 50 may advance the transmission timing of the next reporting data from the management apparatus 10 when the collecting apparatus 50 arrives late. Therefore, the transmission time field 300 may be needed since it is necessary to know whether the management equipment 10 has performed accurate transmission according to the data transmission schedule.

It should be apparent to those skilled in the art that although not shown in the drawings, the report data may further include related information that allows report data such as address information for the data collection device 50 to be transmitted to the data collection device.

Referring again to FIG. 2, in the storage unit 230 of the data collection device 50, report data and alarm / event information collected from the management equipment 10 are stored. Particularly, according to the present embodiment, the data collecting apparatus 50 uses two physical or logically divided storage means as shown in the figure, and transmits raw data And the data classified into the specific criteria as described above are stored in the respective storage units 230. [ For example, the first storage unit 232 stores data classified according to a measurement time period, and the second storage unit 234 stores data according to a received time. The first storage unit 232 stores only the classified report data and the second storage unit 234 stores not only the unclassified report data but also the alarm / Information is also stored.

The data stored in the first storage 232 may be provided to the database 72 of the monitoring system 70 and the data stored in the second storage 234 may be provided to the monitoring / And can be provided to the PC 74.

Hereinafter, a process of collecting data from the management equipment 10 by the data collection device 50 will be briefly described.

FIG. 4 is a flowchart illustrating a process of collecting report data from management equipment by a data collection device 50 according to an embodiment of the present invention. FIG. 5 illustrates another data transfer schedule according to an embodiment of the present invention. It is a table.

Referring to FIG. 4, the data collecting apparatus 50 generates a data transmission schedule (S410) and transmits it to each of the management apparatuses 10-1,..., 10-n (S420). Since the method of generating the data transmission schedule has been described above, redundant description is omitted.

However, according to an example, the data transmission schedule may be transmitted to all the management apparatuses 10-1 to 10-n as information including the schedules of all the management apparatuses 10-1 to 10-n. According to another example, different data transmission schedules may be provided to the respective management equipments 10-1, ..., 10-n as information on the schedule of only the management equipment. In the latter case, a data transmission schedule may be provided to the management equipments 10-1, ..., 10-n through a message transmission service such as SMS provided by the mobile communication network 34. [

Referring to FIG. 5 illustrating another data transmission schedule when all management equipments 10 are provided with the same data transmission schedule, the data transmission schedule includes information on the transmission time and management information Information about the equipment is included. According to the present embodiment, only one management device transmits report data at a certain transmission time, or a plurality of management devices transmit data at a specific transmission time. This may be determined according to the data amount of the report data received from the management equipment as described above.

Referring again to FIG. 4, the management devices 10-1 to 10-n store the received data transmission schedules and generate report data including sensed information periodically measured (S430 and S435) (S440, S445). As described with reference to Fig. 3, the report data includes information on the measurement time.

The management equipments 10-1 to 10-n check the schedule according to the data transmission schedule at step S450 and transmit the report data to the data collection device 50 at the transmission time allocated to the management devices 10-1 to 10- (S460, S470).

The data collection device 50 classifies the received report data according to the measurement time period (S480). The classified report data can be stored in the database 72 of the monitoring system 70, which is an upper system.

Here, although not shown in the drawing, the data collecting apparatus 50 further judges whether or not the report data is properly collected from each of the management equipments 10-1, ..., 10-n according to the data transmission schedule And can perform the sorting operation if the collection of the report data is normally completed for a predetermined period (for example, a period during which the report data is collected one by one from all the management apparatuses according to the schedule). Alternatively, if the reporting data is not normally collected according to the data transmission schedule from some management equipment (for example, when the reporting data is transmitted at a time different from the time according to the schedule), the next transmission schedule of the management equipment Or perform error processing or fault reporting processing.

The method of collecting data of a plurality of devices using the mobile communication network according to the present invention can be implemented as a computer-readable code on a computer-readable recording medium. The computer-readable recording medium includes all kinds of recording media storing data that can be decoded by a computer system. For example, it may be a ROM (Read Only Memory), a RAM (Random Access Memory), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, or the like. In addition, the computer-readable recording medium may be distributed and executed in a computer system connected to a computer network, and may be stored and executed as a code readable in a distributed manner.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that various modifications and changes may be made.
