Description

Integrated failure management device and method using dedicated line modem in digital-frequency common communication FM system

The present invention relates to a digital-trunk radio system (D-TRS) that can be utilized in all systems capable of system failure management by using a terminal server and a dedicated line modem, and more particularly, in operating a D-TRS FHMA system. D-TRS FHMA system enables local operators to collect system failures and provide technical support in a centralized center using dedicated lines, enabling more stable, continuous and efficient local operator management than using dial lines. The present invention relates to an integrated fault management apparatus and method using a dedicated line modem.

In general, in the use of a TRS terminal that provides distribution and logistics services using a vehicle, the user of the TRS terminal usually communicates with the headquarters or the commanding station when moving in the vehicle.

At this time, the vehicle TRS terminal is mounted inside the vehicle and its use is limited to or inside the vehicle.

Currently, the failure management system using a dedicated line of the D-TRS FHMA system is largely composed of a local operator FHMA system 10, a PSTN 20, and a failure management center 30 as shown in FIG.

The local operator FHMA system 10 includes a modem server 1 and a terminal server 2 connected to the modem 1 through an internal port and connecting all data received through the modem 1 from the outside to the FHMA system. A data computer (4) that manages the modem (1) and the terminal server (2) and processes all information relating to data communications, a database server (5) and other system controllers (6) that manage system-wide parameter information. And a switching server 3 connected between the terminal server 2 and the data computer 4, the data server 5, and other system controllers 6.

And the problem management center 30 is composed of a personal computer 31 having a built-in modem (32).

In the conventional D-TRS FHMA system configured as described above, the failure management center 30 uses the dial-up network in the personal computer 31 equipped with the failure management operation software and the internal modem 32 to obtain each local operator system Internet address. The system was connected to each local operator's FHMA system 10, which had a dial-line configuration setup, to collect the system's fault status and provide technical support.

However, since the conventional D-TRS local operator FHMA system 10 is not provided with a dedicated line modem interworking itself, it is not possible to establish a failure management center using a dedicated line.

In case of constructing a trouble management center using a conventional dial line modem 1, when a user of a dial line number is used by another user, the trouble management center 30 cannot access each local operator FHMA system 10. There was a problem that management was unstable and inconsistent, and the technical support for the operators could not be performed smoothly.

The present invention has been made to solve such a conventional problem, the object of the present invention, each local operators in the operation of the D-TRS FHMA system centralized center using a dedicated line to collect system failure situation and technical support The present invention relates to an integrated fault management apparatus and method using a dedicated line modem in a digital-frequency common communication FHMA system that enables local operators to be more stable, continuous and efficient than using a dial line.

The local operator FHMA system 10, the main block in each local operator FHMA system is a four-wire dedicated line modem (1) using a dedicated line, connected to the modem (1) through an internal port and the modem (1) A terminal server (2) that connects all incoming data to the FHMA system, a data computer (4) that manages the modem (1) and the terminal server (2) and processes all information related to data communications; A switching hub which is connected to the database server 5 and other system controller 6 managing parameter information and the data computer 4 and the database server 5 and other system controller 6 to switch signals ( 3) consists of.

The failure management center 40 is composed of a personal computer 42 with built-in failure management operating software and a four-wire dedicated line modem 41 using a dedicated line.

Referring to the operation of the present invention configured as described above is as follows.

Refer to the structure of the integrated fault management center configured using the leased line and refer to the method of interlocking the leased line modem which is not supported by the FHMA system to the system and the algorithm used to manage the failure by accessing each local operator's system from the integrated fault management center. Explain.

First, in the procedure of interworking a dedicated line modem to the FHMA system, as shown in FIG. 3, a terminal server number operating as a service in a database in charge of managing all parameters is inputted, and a terminal server to be used for a dedicated line. Define the port number (step S1).

In addition, the protocol used by the dedicated line modem when connecting to the system from outside is defined as a one-to-one access protocol (step S2).

In the data computer 4 which manages the leased line modem 1 and the terminal server 2 and processes all information related to data communication, the data computer 4 and the system internal internet address of the terminal server 2 are defined. It performs a TCP / IP connection with the terminal server (2), and defines a local Internet address that can log in to the data computer (4) when performing an external system connection (step S3).

In addition, the terminal server (2), which connects to the modem through the internal port and connects all data coming from the modem to the FHMA system, defines the leased line modem speed used, and the terminal server (2) Designate the system internal Internet address that can communicate with the system through (S4 step).

Next, the connection between the dedicated line modem and the terminal server 2 to be used is set as a point to point protocol (step S5).

When this protocol is set, the system can be accessed from the outside and the failure management operation program can be performed in the failure management center 40 to collect failures generated in each operator system.

And by defining a system Internet address automatically assigned by the terminal server (2) when connecting to the system from the outside, the user does not need to enter the system Internet address when accessing the system from the outside (step S6).

Finally, when the terminal server 2 is initialized, a newly connected dedicated line modem configuration is added to the system and interlocked with each other (step S7).

In the four-wire full-duplex dedicated line modem 41 used in the fault management center 40 and connected to the terminal server 2, the asynchronous method is selected as the terminal communication method, the data bit is 8 bits, and the parity bit is no. Set the low stop bit to 1 bit, save it, reset the modem, and initialize it.

Hereinafter, an operation algorithm for accessing each operator system in an integrated fault management center configured by interlocking a dedicated line modem to a system will be described with reference to FIG. 4.

In the four-wire full-duplex dedicated line modem 41 connected to the personal computer 42 with the fault management operating software in the fault management center 40, the asynchronous method is selected as the terminal communication method, and the data bits are set to 8 bits and parity. Set the bit to No and the stop bit to 1 bit, save it, and reset the modem to initialize it.

When the installation of the modem is completed, the personal computer 42 executes a dial-up network, selects an NT-direction connection as the type of modem, and attempts to dial up.

Next, the terminal server 2 performs one-to-one connection protocol (ppp) connection with the leased line modem 41 that is externally connected (step S10).

When the one-to-one connection protocol (ppp) is set, the terminal server 2 assigns a system internet address to the dedicated line modem 41 which attempts to connect from the outside (step S12).

Next, a login and password of a dedicated line modem attempting to connect from the connection unit are input (step S13).

In addition, the login and password input is checked in the database to allow the system access when valid, and to be input again in the case of failure (steps S14 and S15).

If the system is authorized to access the system, it connects to the system using the system internet address assigned by the terminal server.

In addition, when the TCP / IP connection is established, the integrated failure management center 40 performs a failure management program to collect the failure of the system (step S16).

In addition, if you want to terminate the connection in the failure management center, terminate the failure management program and release the established TCP / IP connection (step S17).

In another embodiment of the present invention, it is applicable to all systems for network management using the dedicated line modem 41 and the terminal server 2.

As described above, the present invention can interlock a dedicated line modem that was not interlocked in the D-TRS FHMA system, and can provide more stable, continuous and efficient fault management and technical support by using a dedicated line modem. have.

In addition, there is a reduction in the number of people and equipment required by supporting centers in the way of supporting local operators individually.
