In addition, the failure processing unit 230 generates the failure information in which the identification information of the place where the failure has occurred and the failure facility 110-N is recorded, and transmits the generated failure information to the terminal 500 of the administrator. In addition, the failure processing unit 230 instructs the data management apparatus 300 to provide the status data of the failure facility collected later to the administrator terminal 500. Thereafter, when receiving the job completion information indicating that the failure processing is completed from the data management apparatus 300, the failure processing unit 230 stores the job completion information in the database 400 and outputs the job completion information to the large monitor to monitor that the failure has been normally recovered Recognize to employees.

The authentication unit 240 performs a function of authenticating an administrator in progress of the failure processing. Upon receiving the authentication information of the administrator from the data management apparatus 300, the authentication unit 240 determines whether the authentication information is correct and whether the authentication information is authentication information having full control authority or authentication information having limited control authority On the basis of the manager-specific authentication information stored in the database 400, thereby authenticating the manager. Here, the limited control authority is an authority to control only the failed facility 110-N, and the overall control authority is not limited to the facility 110-N, Lt; RTI ID = 0.0 > 110-N. ≪ / RTI > When the authentication of the administrator is successful, the authentication unit 240 transmits an authentication success message including the limited control authority or the entire control authority to the data management apparatus 300.

3 is a diagram showing a configuration of a data management apparatus according to an embodiment of the present invention.

3, the data management apparatus 300 includes a data collecting unit 310, a plurality of communication modules 321, 322, and 323, a storage unit 330, and a control unit 340 according to an embodiment of the present invention. , And these components may be implemented in hardware or software, or in a combination of hardware and software.

The data collecting unit 310 collects data by performing the object Internet with each facility 110-N. That is, the data collecting unit 310 performs wired or short-range wireless communication with each facility 110-N and collects status data of each facility 110-N.

The status data includes data indicating identification information and status of facilities. If a failure occurs in the facility 110-N, the corresponding failure code is included in the status data.

Each of the communication modules 321, 322, and 323 functions to communicate with different types of communication networks 610, 620, and 630. For example, the first communication module 321 may communicate with the LTE network 610, the second communication module 322 may communicate with the WCDMA network 620, and the third communication module 323 may communicate with the WiFi network 630 ). ≪ / RTI >

The storage unit 330 is a storage unit such as a memory or a disk unit, and can temporarily store facility state data collected by the data collection unit 310. Also, the storage unit 330 stores the failure code of each facility 110-N, and also stores maintenance information of each facility 110-N. The maintenance information includes at least one of a model name of the facility, a construction time, a manufacturer, a manufacturing date, a failure history, and wiring information. In addition, the storage unit 330 stores the facility information related to the specific facility by the facilities 110-N. For example, when the facility is an IP camera, the storage unit 330 may store a switch hub and an uninterruptible power supply (UPS) as facility information associated with the IP camera.

The control unit 340 controls each component of the data management apparatus 300. Specifically, when the data collector 310 collects status data from the facility 110-N, the control unit 340 transmits the collected status data to one of the plurality of communication modules 321, 322, and 323 And transmits it to the control server 200 by using it. At this time, the control unit 340 confirms the communication network set in the main communication network, and transmits the collected state data to the control server 200 using the communication modules 321, 322, and 323 communicating with the communication network.

Meanwhile, the control unit 340 continuously monitors the failure status of each of the communication networks 610, 620, and 630 and temporarily suspends status data transmission if it is determined that a failure has occurred in the main communication network. At this time, if it is determined that the collected status data is the main status data, the control unit 340 may selectively transmit the status data collected using the communication modules 321, 322, and 323 communicating with the sub- 200).

In addition, the control unit 340 can continuously provide status data of the specific facility 110-N that has failed to the designated administrator terminal 500, in accordance with an instruction from the control server 200. [ Upon receiving the failure processing information from the administrator terminal 500, the control unit 340 transmits the failure processing information to the control server 200, and reports to the control server 200 that the failure processing is completed.

In addition to the maintenance information of the faulty facility 110-N, the control unit 340 controls the other facilities 110-N associated with the faulty facility 110-N, May be extracted from the storage unit 330 and provided to the administrator terminal 500. In addition, the control unit 340 selectively permits the control of the facility 110-N based on the control authority of the administrator.

4 and 5, it is assumed that the main communication network is the WiFi network 630, and the communication module communicating with the main communication network is the third communication module 323. FIG.

4 is a flowchart illustrating a method for collecting status data and recognizing a situation in an intelligent facility management system according to an embodiment of the present invention.

4, the data collection unit 310 of the data management apparatus 300 performs object-to-object communication with each facility 110-N, Data is collected (S401). The status data is transmitted to the control server 200 in real time through the WiFi network 630, which is the main communication network, by using the third communication module 323 communicating with the main communication network 630 of the data management apparatus 300 (S403).

Then, the data receiving unit 210 of the control server 200 stores the received state data in the database 400, and the state recognition unit 220 analyzes the state data to determine whether the facilities 110-N are installed The state of the building or the moving means is recognized (S405, S407). That is, the situation recognition unit 220 may analyze at least one of the received state data to recognize at least one of a temperature, a moving state, a number of persons, a power consumption, a fault, and the like. For example, if the received state data is state data indicating the temperature, the situation recognition unit 220 can recognize the temperature of the place where the facilities 110-N are installed, and if the received state data is state data , It is possible to recognize the speed and current position of the moving means by analyzing the previously collected position information and the current position information. As another example, if the received state data is state data indicating the amount of power, the state recognition unit 220 can recognize the current used power. If the received state data is state data indicating a failure, It is possible to recognize that a failure has occurred in the place where the apparatus is installed.

Next, the context recognition unit 220 of the control server 200 determines whether the recognized status is a fault (S409), and outputs the currently recognized status information to the large monitor (S411). On the other hand, the context recognition unit 220 of the control server 200 outputs the failure notification information to the large monitor if the recognized status indicates the failure, and instructs the failure processing unit 230 to process the failure.

Then, the failure processing unit 230 confirms the terminal information (e.g., telephone number, IP address) responsible for the failed facility 110-N in the database 400 (S413). Then, the fault handling unit 230 confirms the faulty area information (i.e., the administrative address where the facility is installed) in the database 400 when the place where the facility is installed is a building. If the place where the facility 110-N is installed is the moving means, the fault processing unit 230 confirms the position information of the moving means from the status data and also identifies the moving means (e.g., vehicle number or train identification information Is confirmed in the database 400. Next, the failure processing unit 230 generates failure information in which information on the place where the failure has occurred, information on the movement means, and facility information of the failure is recorded (S415), and transmits the generated failure information to the terminal 500 of the administrator (S417).

The failure processing unit 230 provides identification information (e.g., a phone number or an IP address) of the administrator terminal 500 to the data management apparatus 300 and transmits status data of the collected failure facility to the administrator terminal 500) to the data management apparatus 300 (S419).

The control unit 340 of the data management apparatus 300 then transmits the status data obtained through the failed facility 110-N to the administrator terminal 500 as well as the control server 200 ), And let the manager who is dispatched to the disability site know the information related to the disability.

When the administrator who has received the failure information visits the obstacle site, he / she establishes a short-range wireless session with the data management apparatus 300 by activating the local wireless communication function of the terminal 500 owned by the user, And forms a wired connection with the data management apparatus 300 via a cable. Then, the manager terminal 500 transmits a control authority request message including control authority authentication information of the manager to the data management apparatus 300 (S423). That is, the administrator terminal 500 transmits a message requesting the right to control the facilities 110-N to the data management apparatus 300.

Then, the control unit 340 of the data management apparatus 300 confirms the authentication information included in the control authorization request message and requests authentication of the authentication information to the control server 200 (S425).

Next, the authentication unit 240 of the control server 200 determines whether the received authentication information is correct and whether the authentication information is authentication information having full control authority or authentication information having limited control authority to the database 400 Based on the stored manager-specific authentication information, the manager is authenticated (S427). That is, the authentication unit 240 authenticates whether the authentication information is correct. If the authentication is successful, the authentication unit 240 determines whether the authentication information is the authentication information having the entire control authority or the authentication information having the limited control authority. Here, the limited control authority is an authority for the administrator to control only the faulty facility 110-N through the data management apparatus 300, and the entire control authority can be granted to all the facilities connected to the data management apparatus 300 It is the controllable authority of the waters 110-N.

Next, when the authentication of the administrator is successful, the authentication unit 240 transmits an authentication success message including the limited control authority or the entire control authority to the data management apparatus 300 (S429).

The control unit 340 of the data management apparatus 300 transmits a message for permitting the control of the facility to the administrator terminal 200 based on the control authority (i.e., the limited control authority or the entire control authority) received from the control server 200 500) (S431).

The administrator terminal 500 outputs the message to the screen, and confirms that the administrator can control the facilities (110-N) through the data management device (300). The manager terminal 500 may request maintenance management information related to the failed facility 110-N to the data management apparatus 300 according to the operation of the manager (S433). That is, when the administrator needs maintenance information related to the facility 110-N in which the failure occurs, the maintenance information can be requested to the data management apparatus 300 using the administrator terminal 500. [

Then, the control unit 340 of the data management apparatus 300 determines whether the manager is an administrator having full control authority. If the manager is a manager having limited control authority, From the storage unit 330 and transmits it to the administrator terminal 500 (S435). The maintenance information includes at least one of a model name of the facility, a construction time, a manufacturer, a manufacturing date, a failure history, and wiring information.

The controller 340 of the data management apparatus 300 may be configured to manage the failed facility 110-N in addition to the maintenance information of the failed facility 110-N if the administrator is an administrator having full control authority The maintenance information of the other facility 110-N is further extracted from the storage unit 330 and the maintenance information of the extracted facility 110-N and maintenance of the other facility 110- And transmits the maintenance information to the administrator terminal 500 (S435). The control unit 340 of the data management apparatus 300 may notify the administrator that the administrator has full control authority because the failure of the specific facility 110- The maintenance information of the faulty facility 110-N and the maintenance information of the other facility 110-N associated with the faulty facility are extracted from the storage unit 330 and transmitted to the administrator terminal 500 do. For example, when the failed device is an IP camera, the control unit 340 extracts maintenance information of a network device (e.g., a hub) associated with the IP camera in addition to the maintenance information of the IP camera, and transmits the maintenance information to the administrator terminal 500 .

The control unit 340 may collect status data of the facility 110-N in real time and provide it to the administrator terminal 500 when the controller 340 receives the facility status data from the administrator terminal 500. In this case, the control unit 340 may selectively provide status data of the other facility 110-N associated with the failed facility 110-N to the administrator terminal 500 according to the control authority of the administrator .

Next, the administrator identifies the cause of the failure of the facility 110-N based on the information acquired through the manager terminal 500, and transmits a control message to the data management apparatus 500 via the manager terminal 500, (S437). The control message includes identification information of a facility to be controlled and a control value (e.g., parameter setting value).

Then, the data management apparatus 300 confirms the identification information of the facility included in the control message, and transmits the control message to the facility 110-N corresponding to the identification information, ) Causes the setting state or parameter to be changed according to the control message (S439). At this time, if the administrator terminal 500 has the limited control authority, the data management apparatus 300 controls only the failed facility 110-N to be controlled through the control message, whereas the administrator terminal 500 controls the entire control authority If so, all the facilities 110-N can be controlled via the control message.

The data collector 310 of the data management apparatus 300 acquires the state data of the facility 110-N that has failed and the controller 340 transmits the state data to the administrator terminal 500. Then, the administrator terminal 500 outputs the status data to the screen and notifies the administrator whether the failure status has been restored.

If it is determined that the failure has been restored, the manager transmits the job completion information including the authentication information to the data management apparatus 300 (S441).

Then, the control unit 340 of the data management apparatus 300 transmits the job completion information to the control server 200. At this time, the control unit 340 determines whether or not the fault related state data is no longer collected in the faulty facility 110-N. If the fault related state data is not collected, the controller 340 determines that the fault processing is normally completed, Information to the control server 200 (S443). In addition, the control unit 340 records the data from the occurrence of the failure to the recovery of the failure in the failure history information of the facility, and updates the maintenance information of the failed facility 110-N.

Next, the failure processing unit 230 of the control server 200 stores the job completion information in the database 400 and outputs the completed information to the large monitor so that the monitoring staff can recognize that the failure has been normally recovered.

On the other hand, the administrator accesses the data management apparatus 300 remotely via the network 600 to proceed with the authentication of the control authority. If the authentication is successful, the administrator changes the setting value of the one or more facilities 110- It can also remotely handle facility faults. In addition, the manager may cope with the failure by replacing the parts due to a physical failure in the facility 110-N. In this case, the manager terminal 500 transmits the job completion information to the data management apparatus 300 when it is confirmed that the parts 110-N are normally operated by replacing the parts.

5 is a flowchart illustrating a method of processing status data in a data network management apparatus in a network failure according to an embodiment of the present invention.

5, the control unit 340 of the data management apparatus 300 monitors status of each of the communication networks 610, 620, and 630 using the respective communication modules 321, 322, and 323 (S501) . In this case, the control unit 340 can monitor the status of each communication network based on the sensitivity of the wireless signal received from the communication module in the case of a communication network performing wireless communication. For the communication network performing wired communication, (E.g., ping) may be used to monitor the status of the network.

The control unit 340 of the data management apparatus 300 determines whether a failure has occurred in the main communication network 630 in step S503. If it is determined in step S503 that a failure has occurred in the main communication network 630, (S505). The signal sensitivity of each of the other communication networks 610 and 620 is checked. Next, the data management apparatus 300 selects a communication network having the best signal sensitivity among the other communication networks 610 and 620 as the subordinate communication network (S507).

The control unit 340 then collects the status data of the facility 110-N from the data collection unit 310 (S509), and the collected status data is stored in the status data (i.e., the general status data ) Or status data indicating a failure (S511).

If it is determined that the collected state data is general state data, the control unit 340 maps the state data to the state data collection time and stores the collected state data in the storage unit 330 (S513). The control unit 340 checks whether the failure of the main communication network 630 is restored through the third communication module 323 communicating with the main communication network 630 in step S515. If the failure is restored, the third communication module 323 Sets up a session with the main communication network 630 and transmits the stored status data stored in the storage unit 330 to the control server 200 at step S517.

On the other hand, if it is determined that the failure of the main communication network 630 has not been restored, the control unit 340 determines whether or not a predetermined period (for example, five minutes) A plurality of status data is selected from the data (S519). At this time, the controller 340 selects the first stored state data from the state data for each facility 110-N stored in the storage unit 330, for each facility 110-N. That is, the control unit 340 selects the first stored status data among the status data collected through the same facility 110-N as transmission target data of the facility 110-N, N) by one for each facility 110-N.

Next, the control unit 340 transmits the selected plurality of state data to the control server 200 (S521) using the communication module 321 or 322 communicating with the selected sub communication network (S521) To be aware of the status and status of each facility 110-N. In addition, the control unit 340 deletes the state data transmitted to the control server 200 to the storage unit 330.

On the other hand, if it is determined that the collected state data is faulty data, the control unit 340 uses the communication module 321 or 322 communicating with the selected sub-communication network in step S507 to transmit the state data to the control server 200 (S523).

The description with reference to FIG. 5 corresponds to one cycle. If the failure of the main communication network 330 continues, the steps after S509 may be continuously repeated.
