Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an apartment complex home network installed with a local server adopting a remote management system of a home network according to the present invention.

Referring to Figure 1, the apartment complex home network, the home network 10 is installed for each household of the apartment, the home network (10, 20) for each household remotely by each building or common entrance server 40 Local server 30 is installed to manage from. An internet network 50 is connected to the local server 30, and a security company server (eg, S1 server) and external client terminals 70 may be connected to the local network 30.

The home network 10 installed by generations may be connected to an information terminal such as a home server 11 or a home pad 12, and a portable computer 13 capable of controlling home appliances through the home server 11. In addition, various detectors 14 and various home appliance terminals 15 may be connected. Here, the information terminal is used when collectively referred to as home server and home pad.

The home server 11 is a main device of the home network, and all sub devices (home pads, detectors, and extension phones) are connected and managed.

The home pad 12 may be a type of SHN-810 or SHN-815 as an interface terminal for a user to use a home network product.

The local server 30 is a system for remotely managing a home server and a home pad. The local server 30 downloads the software of the home server and the home pad, monitors the normal operation of the information terminal, and analyzes and manages statistical data on the information terminal. It is a server that can perform such functions.

The local server 30 is configured by mounting a database and a web server on a commercial server and implementing and mounting software for remotely managing a home server.

FIG. 2 shows a functional module of the local server shown in FIG. 1. Referring to FIG. 2, the local server 30 includes a home server and home pad automatic authentication module 31, a home server and home pad parameter management module 32, and a home server and home pad S / W upgrade module 33. ), A monitoring module 34, a statistics module 35, a home server management module 36, and a user management module 37.

When the home server 11 or the home pad 12 of the home network is connected using the network, the home server and the home pad automatic authentication module 31 receive the authentication information of the corresponding information terminal and perform authentication. Store information in the home network and provide the home network information to each information terminal.

When the home server 11 is installed and supplied with power for each household in the cyber apartment complex, the home server 11 is booted and the local server 30 has its own information (its serial number, IP address, user ID, password). Transport, apartment building, apartment lake, apartment type).

The home server and home pad automatic authentication module 31 receives this information, stores it in a database, and lowers parameter values (environmental setting values) that should be set in common to each home server. The common parameters may include security server IP, main server IP, security office IP, common entrance IP, internal / external gatekeeper IP, LONWORKS server IP, access control server IP, parking control server IP, and the like.

The home server receives this parameter information and stores it in its database. This authentication process is automatically performed every time the home server is booted, and even if the authentication information of the home server is changed, the authentication process occurs and the database of the local server is changed.

Homepad also goes through the same procedure, homepad sends the serial number, its own IP address, and home server IP address to the local server, the home server and home pad automatic authentication module 31 is responsible for Save it to your database and pass the parameter values to Homepad as you would on a home server.

When normal authentication is performed on the home server and the home pad, a log file is automatically generated so that each information terminal can check when authentication has occurred.

If the home server and home pad parameter management module 32 changes the parameter values used by the home server and home pad, the parameter value is set for the entire information terminal instead of directly visiting the household and modifying the set value. Performs the function of lowering.

You can change the parameter value of the selected home server list by selecting the home server list to be changed in the UI (User Interface) of the local server and executing the "Terminal Parameter Push" menu. In addition, if a normal parameter change is made, a log file is automatically generated so that each information terminal can check when the parameter change has been performed. If the parameter change fails, a failure list is stored in the database.

The server and home pad software upgrade module 33 can download the changed software online from the remote when the home server 11 and home pad 12 have been upgraded or a bug is found in the system. have.

In case of the home server 11, if there is S / W to be upgraded, a method of pushing from the local server to the corresponding home server is used. For the smooth operation of the home server, the automatic push is performed from 12 am to 6 am. You can also design a so that the download occurs at this time by running an auto push server.

On the other hand, the home pad 12 checks whether there is a S / W to upgrade to the local server once a day in each home pad, and if there is a corresponding S / W to download the S / W.

That is, when performing the installation or version upgrade of the software, it is possible to perform the installation and version upgrade of the software by determining whether the installation and version upgrade of the software is necessary by sending and receiving software information with each information terminal periodically or at any time. Can be.

In addition, whether a normal download is performed or a download is unsuccessful, a log file is automatically generated so that the download time, download file name, and download success can be checked.

In addition, by generating history information on software installation and version upgrade of the corresponding information terminals, it is possible to provide statistical information for each period, terminal, software for each request.

The monitoring module 34 largely performs system monitoring and terminal monitoring (home server, home pad, subphone).

System monitoring is performed on the local server, Oracle Server, File Push Server, Terminal S / W Download Server, ID Check Server, HS Authentication Server, HS Push Server, HS Log Server, HS Monitor Server, Terminal Authentication Server, Terminal Parameter Modification By monitoring the status of Server, Logger Server, and Time Server every 2 minutes, you can check the server that does not operate normally and take action to correct the error.

On the other hand, the terminal monitoring for the home server, home pad, subphone, etc. can monitor the status of the information terminal and the HA terminal (subphone). It is possible to monitor the status of 500 home servers managed by local server and subphones and home pads managed by the local server with true / false value at specific time interval (ex. 10 minutes).

The statistical module 35 calculates traffic related statistics and data on terminal distribution statistics.

Traffic related statistics can check the downloaded capacity by period, time and terminal type based on the information downloaded by the information terminal. The terminal distribution statistics is a function that can confirm the increase trend of the entire terminal system, and can grasp the status of terminals distributed by OS version.

The home server management module 36 performs home server time management and home server user ID duplication check.

Since home server time management cannot have a clock on its own, it functions to download time information from the local server to the home server once a day.

The duplicate check of home server user IDs does not allow duplicate home IDs to be registered in the local server.

The user management module 37 checks the power line on / off / dimming state of the home network through the information terminal and performs a function of controlling the power line of the home network using the network remotely. In addition, the outgoing crime prevention function that can query and set the "going out / security" setting status of the home, and visitor image information search to support the visitor visiting the home from the outside (school or company etc.) when going out Function can be performed.

FIG. 3 is a diagram illustrating a connection relationship between a local server, a home server, and a home pad in FIG. 1.

As shown, the local server 30 is connected to the home server 11 and the home pad 12 by Ethernet to communicate with the TCP / IP socket, and the operation of all functions of the local server 30 is performed as described above. Implemented via TCP / IP communication with terminals.

In order to perform TCP / IP communication, it is possible to define a communication protocol that can be shared between the local server 30, the home server 11, and the home pad 12, and to program and implement the protocol to operate.

If an error occurs when exchanging packets between the local server 30, the home server 11, and the home pad 12, the number of retries is set to 7 times, and all packets are encrypted by an authorized encryption algorithm to enhance security. do.

The local server 30 uses a database to store information about the home server 11 and the home pad 12, software and software download-related information, and all the data for the convenience of the local server administrator in a web browser. Implement as GUI (Graphic User Interface) environment to check.

The software download performed by the home server and the home pad software upgrade module 33 will be described in more detail.

In the case of the home server 11, a download-related signal (download push signal) is provided by the local server 30 whenever necessary, so that the relevant software can be downloaded and upgraded. A software download related signal (polling) is sent to the server to check whether there is software to download.

If there is software to be downloaded, the local server 30 is connected to the local server 30 at the download scheme time indicated by the local server 30 so as to download the software and implement it to be restarted.

To this end, the following communication protocols should be promised for software download of information terminal and local server.

Table 1 shows the protocol between local server and home server.

Interlocking transmission direction Interlocking format Local Server-> Home Server FROM_LS_FILE_UPGRADE_REQ Home Server-> Local Server TO_LS_FILE_UPGRADE + SN [6] + TER_TYPE [1] + TIME_STAMP [12] Local Server-> Home Server FROM_LS_FILE_INFO + TIME_STAMP [12] + FILE_NAME [20] (FILE_NAME: blank means no file to download Home Server-> Local Server TO_LS_UPGRADE_RESULT + STATE [1] (STATE: 0 is success, 1 is failure)

Referring to Table 1, we look at the protocol between local server and home server.

1. The local server issues a file upgrade signal to the home server.

2. The home server receives the file upgrade signal and returns the local server's serial number, terminal type, and time of last download (timestamp).

3. The local server, which receives the serial number, terminal type, and time stamp information from the home server, finds a file list that is newer than the received time stamp, and returns the file's time stamp and file list to the home server.

4. The home server takes the information received from the local server and connects to the local server via the tftp protocol to download the list of files passed in from 3. Throw 0 if the file downloads successfully, or 1 if the file fails to download.

At this time, the local server leaves the log information of the download as a log file based on the ack signal received from the home server.

Table 2 shows the protocol between local server and home server.

Interlocking direction Interlocking format Homepad-> Local Server TO_LS_FILE_UPGRADE + SN [6] + TER_TYPE [1] + TIME_STAMP [12] Local Server-> Homepad FROM_LS_FILE_INFO + TIME_STAMP [12] + FILE_NAME [20] (FILE_NAME: blank means no file to download Homepad-> Local Server TO_LS_UPGRADE_RESULT + STATE [1] (STATE: 0 is success, 1 is failure)

Referring to Table 2, we look at the protocol between the local server and homepad.

1. HomePad is a local server once a day (random time set by the local server) that sends HomePad's own serial number, terminal type, and timestamp to send an upgrade signal to check if there are any files to be upgraded.

2. Upon receiving this signal, the local server checks if there is a file list that is newer than the time stamp of the received home pad and throws the file list and time stamp to the home pad.

3. Homepad downloads the file list by ftp to local server based on the file list and time stamp information. If the file is downloaded successfully, 0 (success) is returned. If the file fails to download, 1 (fail) is thrown to the local server.

At this time, the local server leaves the log information of the download as a log file based on the ack signal received from the home pad.

4 shows a procedure in which the local server 30 upgrades the software of the home server 11 by the home server and the home pad software upgrade module 33 in the state where such a communication protocol is premised.

As illustrated in FIG. 4, the software download function is performed by exchanging packets for TCP / IP communication between the local server and the home server.

First, the software upgrade push message is transmitted from the local server 30 to the home server 11 (S1). The home server 11 transmits the time stamp for the software maintained at the present time to the local server 30 (S2). The local server 30 compares the time stamp received from the home server 11, extracts a file name and a time stamp to be downloaded by the home server, and transmits the file name to the home server (S3).

The home server 11 accesses the local server 30 by TFTP (S4), downloads the corresponding file (S5), and passes the download result (SUCCESS / FAIL) to the local server 30 (S6).

5 shows a procedure in which the local server 30 upgrades the software of the home pad 12 by the home server and the home pad S / W upgrade module 33.

The home pad 12 transmits a time stamp for the software held by the home pad 12 to the local server 30 at the present time (S11). The local server 30 compares the received time stamp and transmits the file name and time stamp to be downloaded to the home pad (S12).

The home pad 12 connects to the local server 30 by FTP (S13), downloads a file (S14), and passes the download result (SUCCESS / FAIL) to the local server (S15).

Information about software downloads can be checked by accessing the web-based interface provided by the local server.

Let's look at the monitoring performed by the monitoring module 34 in more detail.

In order to monitor the terminal, first, mapping information such as apartment building / house number, home server serial number, terminal serial number, and IP address of the information terminal in the household is built in the DB. You can monitor the current status of various terminals controlled by the home server.
