The management device 20 is a device managed by the control server 30 and may be called, for example, an RTU (Remote Terminal Unit), and is a variety of input / output devices including sensors and the like. As an easy example, assuming that the system according to the present embodiment is applied to the water quality management system, the management equipment 20 may be a device installed in each block (a sensing point to be managed) to measure and report the flow rate.

The control server 30 collects data from the management equipments 20 and provides them to a monitoring device (not shown) of the control room, which is an upper system. For example, the administrator can check the collected data from each management equipment 20 at any time using the monitoring device.

The 3G modem 10 is connected to the management equipment 20 and provides data requested by the control server 30 such as sensing data by the management equipment 20 to the control server 30 through the WCDMA network 40 .

That is, the 3G modem 10 according to the present embodiment accesses the control server 30 through the WCDMA network 40 to transmit and receive data. Accordingly, the communication line is used only when data is actually transmitted and received, It is possible to improve the efficiency of line utilization as compared with a method using a leased line.

The use of the 3G modem 10 allows the control server 20 to transmit data as it is connected to the management equipment 20 as it is. It is not necessary to have a separate program for controlling the program.

Referring to FIG. 2 showing a second generation communication network, in the existing second generation communication network, the management equipment 20 and the control server 30 communicate using a CDMA modem. The data on the site is converted into a voice signal by a CDMA modem Transmitted to the base station, and then converted into a data signal through the IWF. For reference, the IWF (interworking function) is a boundary gateway device that converts digital to analog between a multimedia terminal (MMT) and analog STU-III. That is, in the case of using the second generation communication network of the circuit communication method, since the 1: 1 data transmission is performed between the site (i.e., management equipment 20) and the control server 30, A modem is required as many as the number of management equipments 20.

3, which shows a packet communication mode WCDMA network 40, the data of the management equipment 20 is transmitted to the control server 20 through a SGSN (Serving GPRS Support Node) that handles / controls packet information, (30). According to this, the control server 30 can perform 1: n data communication using one Internet-dedicated line by transmitting and receiving data through the packet network. Also, in the WCDMA network 40, the communication cost is charged according to the actual size of the data to be transmitted / received, so that the charge is lower than the modem of the conventional CDMA method under the same condition.

The control server 30 generates a schedule for when the 3G modems 10 connected to the respective management equipments 20 are to be connected to the WCDMA network 40 And the like. In other words, the 3G modems 10 are connected to the WCDMA network 40 at a time assigned to them according to the set schedule, and are assigned IP addresses to attempt connection to the control server 30. As described above, the schedule for the connection time may be generated in the control server 30 or may be generated in the 3G modem 10 itself according to a predetermined rule.

Hereinafter, the configuration of the 3G modem 10 and the control server 30 connected to the management equipment 20 using the WCDMA network 40 shown in FIG. 1 and the process for controlling the management equipment 20 will be described .

FIG. 4 is a block diagram illustrating a configuration of a 3G modem 10 for a WCDMA network 40 according to an exemplary embodiment of the present invention. FIG. 5 is a flowchart illustrating a process in an overall system according to an exemplary embodiment of the present invention. 6 is a flowchart illustrating a connection management process to a WCDMA network 40 that is processed in a 3G modem 10 according to an embodiment of the present invention. Is a table showing connection schedule information according to the connection schedule information.

5, the 3G modem 10 accesses the WCDMA network 40 from time to time according to predetermined rules or schedules and reports the information to the control server 30 so that the 3G modem 10 and the control server 30 ) Performs communication. The 3G modem 10 accesses the WCDMA network 40 to acquire an IP address when it is recognized that the connection time to be connected to the WCDMA network 40 is present in step S510 ), And reports to the control server 30 that the current communication is possible by accessing the control server 30 using the corresponding IP address (S530).

Although not shown in the drawing, the control server 30 can generate and provide a schedule for the time when the 3G modem 10 is connected to the WCDMA network 40, as described above. Accordingly, the 3G modems 10 access the control server 30 via the WCDMA network 40 in accordance with the received schedule.

The control server 30 can identify the management apparatus 20 through the identification information (e.g., telephone number) of the corresponding 3G modem 10 and can acquire data to be acquired from the management apparatuses 20 To the 3G modem 10 (S540). A plurality of 3G modems 10 may be connected to the control server 30 at the same time. The control server 30 allows each of the 3G modems 10 to connect to different ports, Or to allow each of the 3G modems 10 to transmit their own phone number when accessing, thereby distinguishing each.

When the request data is received, the 3G modem 10 transmits the request data to the management device 20 (S550). When the response data is received from the management device 20 (S560), the 3G modem 10 transmits the request data to the management server 20 S570). For example, when the 3G modem 10 accesses the control server 30, the control server 30 recognizes that the management equipment 20 is connected, transmits a data collection request and a control command, And transmits it to the management equipment 20 after the 3G modem 10 receives it. If there is data to be sent to the control server 30 by the management device 20, when the management device 20 transmits the corresponding data to the 3G modem 10, the 3G modem transmits the data to the control server 30 . That is, the 3G modem 10 performs a function of intermediating data between the management equipment 20 and the control server 30.

In the conventional processing system in the control system using the second-generation communication network, the control server 30 calls the CDMA modem connected to the management equipment 20 via the CDMA modem connected thereto and acquires necessary data by connecting to the management equipment It was a way to go. According to the present embodiment, similar to the processing method in the above-described conventional system, the control server 30 can be processed in the same manner as the control server 30 connects to the management equipment 20 by the 3G modem 10 that intermediates the data Therefore, even if the configuration of the existing management equipment 20 and the control server 30 and the related programs are not largely changed, the present invention can be applied as it is, and the cost for implementing a new system can be minimized.

The control server 30 categorizes and manages the received data by each management equipment 20. According to an example, when the response data is transmitted to the control server 30, the 3G modem 10 may generate and provide transmission time information, which is information on the transmission time. In addition, the management equipment 20 scattered in various sites transmits data to the control server 30 according to the set time. In the conventional exclusive line and second generation CDMA communication, since the data is transferred sequentially, data collection time In the case of the WCDMA network 40 using the TCP / IP communication method, although the time for transmitting the packet may be delayed according to the state of the communication network, according to the present embodiment, even if the response data is received late, Since the transmission time can be known by the information, it is possible to easily recognize when the data is transmitted. Therefore, the control server 30 can classify and manage the data from the respective management equipments 20 according to the transmitted time zone, and it is possible to monitor each time period.

4, the 3G modem 10 according to the present embodiment includes a communication unit 410, an interface unit 420, a message receiving unit 430, a storage unit 440, And a control unit 450. The control unit 450 may include a connection control unit 451, a data mediation unit 453, and a connection holding unit 455. [ It is to be noted that some components (for example, a message receiver) including each component of the controller 450 need not necessarily be implemented in hardware but may be implemented in software like a program that performs the function Will become more apparent to those skilled in the art from the description.

The communication unit 410 is a component for communication through the WCDMA network 40. Since the communication through the WCDMA network 40 is still performed in various devices (e.g., a smart phone, etc.) .

The interface unit 420 may be implemented as a wired communication module such as a cable or a wireless communication module using a local communication technology such as bluetooth, for connection with and communication with the management equipment 20.

The message receiver 430 is for receiving a message by a message transmission service such as a short message service (SMS) transmitted from a management server. According to an example, the 3G modem 10 receives a SMS message from a management server, The connection to the network 40 can be attempted. As will be described later, the 3G modem 10 periodically connects to the WCDMA network 40 according to the established connection schedule, and the connection to the WCDMA network 40 is performed depending on whether the SMS message is received regardless of the connection schedule It can be.

The storage unit 440 may store information necessary for each constituent unit of the 3G modem 10 to perform each function such as connection address information of the control server 30 and information on the connection schedule as described above .

The control unit 450 performs overall control of each component of the 3G modem 10 and connects to the control server 30 through the WCDMA network 40 in accordance with the connection schedule and is connected to the control server 30 Management equipment 20 and performs a function of allowing the connection to the WCDMA network 40 to be maintained so as not to be disconnected for a predetermined time (hereinafter referred to as " holding time ").

The data intermediation unit 453 of the control unit 450 exchanges data between the control server 30 connected through the WCDMA network 40 by the communication unit 410 and the management equipment 20 connected by the interface unit 420, . As described above, the data intermediation unit 453 can transmit the transmission time information together with the data from the management equipment 20 to the control server 30, and the control server 30 can use the transmission time information And sort the data received from each management equipment 20 by transmission time.

The connection control unit 451 of the control unit 450 controls the communication unit 410 according to the set connection schedule and allocates IP from the WCDMA network 40 to access the control server 30. According to an example, the connection control unit 451 is provided with a function of setting information on the control server 30 to be connected, and can designate the IP and the connection port (PORT) of the control server 30.

According to an example, the connection schedule described above can be received from the control server 30, for example, the connection schedule of the day can be provided to each management equipment 20 once a day.

The connection control unit 451 basically tries to connect to the WCDMA network 40 in accordance with the set connection schedule and controls the connection between the control server 45 and the management equipment 20 in accordance with the amount of data transmitted and received between the control server 30 and the management equipment 20. [ . For example, the connection control unit 451 can adjust the next connection schedule with reference to the amount of data transmitted and received by the data intermediation unit 453. As an easy example, if the amount of data mediated so far is more than 50 megabytes (Mbyte), an alarm is sent to the administrator via SMS to determine whether or not to connect next time.

According to another example, the connection control unit 451 may measure the amount of communication packets transmitted and received with the control server 30 for a predetermined period of time, and adjust the connection schedule by referring to the available communication amount and the communication packet amount.

7, assuming that a connection schedule for connecting to the WCDMA network 40 is set every 10 minutes, the amount of communication packets transmitted and received using the WCDMA network 40 so far is summed up , It is determined whether or not to connect next time (for example, 10:00 o'clock time) using the sum of the summed communication packet and the available packet amount. As an easy example, if the amount of available packets is low, the connection schedule may be adjusted to reduce the number of connections.

The connection holding unit 455 functions to prevent the connection to the WCDMA network 40 from being released during a predetermined holding time (for example, 1 to 300 seconds, etc.). Generally, in a third generation network such as the WCDMA network 40, a connected session is released if there is no packet to be transmitted or received. In order to prevent this, in order to maintain a session connected with the control server 30 during a preset holding time, the connection holding unit 455 may not transmit / receive data for a certain period of time (shorter time than the session is released) , And directly transmits data to the control server 30 through the WCDMA network 40. The data may be dummy data having no meaning in the control server 30. [ The dummy data in this embodiment is merely the data transmitted to the control server 30 in order to maintain the connection. In the control server 30, The term " unused " means data that is not used, and the form and contents thereof can be variously set without being limited to the term.

According to this, by maintaining the connection using the minimum data in the 3G modem 10, there is no need to continuously transmit data from the lower management apparatus 20 or the higher-level control server 30 in order to maintain communication So that unnecessary data transmission / reception can be prevented in each of the devices, and a wasted communication cost can be prevented.

Referring to FIG. 6 illustrating the embodiment, the 3G modem 10 accesses the WCDMA network 40 and starts counting time (S610). That is, the time is counted so that the dummy data can be transmitted before the time at which the connection is released (for example, the time T) elapses, and also the time at which the holding time (for example, the time C) The time is also counted.

Then, the 3G modem 10 checks whether data transmission / reception exists (S620), and counts T time again if it exists.

If it is determined in step S630 that the T time has not elapsed without data transmission / reception, the process proceeds to step S620. In step S620, it is determined whether the T time has elapsed.

If the retention time has elapsed, the connection to the WCDMA network 40 is released (S660). If the retention time has not yet elapsed, the dummy data is transmitted (S650) to prevent the connection session from being automatically released from the WCDMA network.

According to the present embodiment, the 3G modem 10 itself is provided with a function of allowing the connection to be maintained during the maintenance time, so that the control server 30 and the management equipment 20 are not required to maintain the connection It is not necessary to perform transmission of the data.

Although not shown in FIG. 4 showing the configuration of the 3G modem 10, according to another example, the 3G modem 10 may further include an event monitoring unit. Since the 3G modem 10 has a communication function through the WCDMA network, the 3G modem 10 can transmit specific event information using a message transmission service such as SMS to the administrator (or the control server 30) by using this communication function. According to an example, the 3G modem 10 is connected to the intrusion detection system provided in the area where the management equipment 20 is installed, by a separate signal line. When the event for intrusion is received from the intrusion detection system, And transmits event information about the event to the terminal of the administrator or the control server 30 using the SMS. According to the present embodiment, in a separate system such as the above-described intrusion management system for the management device 20, by using the communication function of the 3G modem 10 connected to the management device 20, , A WCDMA network). Therefore, it is possible to reduce the cost of constructing the whole system. According to the present embodiment, it is important that an intrusion of an intruder is grasped in real time. Therefore, without access to the management server 30 by the 3G modem 10, event information is transmitted in real time using a message transmission service such as SMS You can do it.

Hereinafter, the configuration of the control server will be described.

8 is a block diagram illustrating the configuration of a control server according to an embodiment of the present invention.

8, the management server 30 includes a communication module 810, a storage module 830 and a control module 850. The storage module 830 includes a first storage unit 832 and a second storage unit 834 and the control module 850 may include a schedule management unit 852 and a data management unit 854. [

The communication module 810 is a communication means for transmitting / receiving data to / from the 3G modems 10, and the communication through the WCDMA network 40 will be obvious to those skilled in the art, so that a detailed description of the communication module 810 will be omitted.

The control module 850 generates a connection schedule containing information on connection times to be connected to the 3G modems 10 and collects necessary data from the corresponding management equipment 20 through the connected 3G modem 10.

The schedule management unit 852 of the control module 850 generates and manages connection schedules, and according to an example, generates a connection schedule according to a specific criterion. For example, a connection schedule may be created corresponding to the priority set in each 3G modem 10 or the corresponding management equipment 20, and the priority may be preset by the administrator, or the priority of the 3G modem 10 But may be set differently depending on the connection history or the data acquired from the management equipment 20. [ As an easy example, it may be preferable to perform collection of frequent data as the amount of change in sensing information according to previously acquired data from an optional management device 20 increases. In this case, the priority order of the management device 10 is Can be set high. In other words, if the number of management devices 20 to be managed becomes large, it is necessary to select the priorities and acquire data from the management devices more frequently. In this case, The higher the ranking, the higher the number of connections of the 3G modem 10 connected to the management equipment 10. Of course, this is only an example, and it is natural that various criteria for determining the priority can be used.

As another criterion for setting the connection schedule in addition to the above-described priority, the amount of data transmitted / received by each 3G modem 10 can be used. For example, if it is assumed that the amount of data previously transmitted and received by any 3G modem 10 is higher than a certain level, a connection schedule can be generated so that the number of connections is smaller for efficient use of communication charges.

According to another example, each management device 20 generates a sensing schedule related to time information for generating sensing data during a day, provides the sensing schedule to the control server 30 via the 3G modem 10, 30) can generate a connection schedule using the respective sensing schedules. For example, a connection schedule is generated so that the 3G modem 10 according to the management equipment 20, which frequently generates sensing data, accesses more frequently.

According to another embodiment, the schedule management unit 852 may generate a plurality of connection schedules. A priority scheduling schedule is generated as a first schedule to be provided to each 3G modem 10, a sub schedule is generated if necessary, and the schedule is provided to the 3G modems 10 again. As an easy example, the schedule management unit 852 analyzes data collected from the management equipment 20 for a predetermined time (for example, one hour) after transmitting the connection schedule according to the first schedule to the 3G modem 10 And the efficiency of the schedule is measured. If the measured efficiency is equal to or less than a predetermined standard, a subschedule can be generated and provided as the second schedule. Accordingly, the 3G modems 10 are connected in accordance with the sub-schedules. Of course, efficiency may also be determined for the sub-schedules, and according to one example, 3G modems 10 may be allowed to connect according to another schedule (or previous schedule) if efficiency is less.

The criterion of the above-mentioned efficiency may be determined depending on, for example, how much required data is acquired.

Also, the sub-schedule may not be provided only when necessary, but may be provided in advance to the 3G modems 10 so that the 3G modem 10 may store the sub-schedule, The 3G modems 10 may use the sub-schedule when it is determined that the sub-schedule is dropped.

In summary, the schedule management unit 852 sets a connection schedule for connection time points of the 3G modems 10 according to a preset reference, and when a schedule change is required, the connection schedule is adjusted to transmit relevant information via SMS or the like to provide.

The data management unit 854 functions to sort the data collected from the management equipments 20 according to preset criteria. The classification criteria of the data use the sensing time of the sensing information according to the data. That is to say, data is grouped according to sensing information measured at the same or a similar level or more at a similar time.

This is because the management equipment 20 senses the sensing information and transmits the data to the control server 30 at a time point when the corresponding 3G modem 10 is connected according to the connection schedule, The control server 30 classifies the collected data according to the sensing time (i.e., measurement time) for accurate monitoring.

The storage module 830 stores data collected from the management equipments 20, and alarm / event information. Particularly, according to the present embodiment, the control server 30 uses two physical or logically divided storage means as shown in the figure to store raw data received from the management equipment 10 And stores the data classified into the specific criteria into each of the storage means 832 and 834). For example, the first storage unit 832 stores data classified by the measurement time period, and the second storage unit 834 stores the data in the order of the received time. The first storage unit 832 stores only the classified data and the second storage unit 834 stores not only the unclassified data but also the alarm / event information from the management equipment 20 Are stored together.

The processing method in the control system using the WCDMA network according to the present invention described above 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.
