The present invention relates to a relay module monitoring apparatus in a repeater system, and more particularly, the plurality of relay modules using a main controller configured on a separate circuit board from a relay module controller equipped with a plurality of relay modules. It relates to a device for controlling and monitoring.

Recently, commercially available mobile communication methods include cellular, PCS, WCDMA, WiBro. Such a conventional mobile communication system provides communication services to a plurality of mobile communication terminals by base stations installed one by one in a predetermined cell unit. At this time, each base station is fixedly installed, but the terminal is changed according to the location of the users, it may be located in the shaded area of the mobile communication radio waves. The radio shadow area may be an interior of an underground building such as a subway station or an underground shopping mall, or an area that is far from the base station so that radio waves cannot reach it.

Therefore, in order to eliminate the radio wave shadow area, a plurality of repeaters are separately installed in the radio wave shadow area to provide a smooth call service.

In addition, the repeater system currently in use is equipped with various repeater modules using RF or light and the repeater module for controlling wired and wireless communication with a plurality of mobile communication terminals, or communication with a base station or another repeater system behind the repeater system. It consists of a main controller including a relay module controller capable of controlling and the main CPU for controlling the relay module controller.

However, such a repeater system is located at a remote location from the base station due to the nature of its use, and is usually operated unattended. Therefore, the failure that occurred in the plurality of relay modules installed in the repeater system could not be immediately confirmed at the base station.

Therefore, in order to detect a failure of the relay module, a separate sub-CPU for automatic monitoring of the repeater is installed in the relay module controller, and when the failure is detected in the at least one relay module mounted on the relay module controller, Remote monitoring methods and apparatus have been used to transmit information about the relay to the administrator for the repeater.

In the communication module monitoring apparatus described above, the mounting unit on which the relay module is mounted is provided with a sub-CPU designed specifically for each relay module. The sub CPU monitors the current state of the relay module mounted in the mounting unit and transmits the result to the main controller.

As described above, the sub-CPU of the relay module controller is provided for the relay module controller specialized for each relay module of each manufacturer, and therefore, there are many limitations in the selection of the relay module that can be mounted on the relay module controller.

In addition, such a configuration problem of the repeater system has caused a problem that it can not dynamically respond to the upgrade of the recent mobile communication system. More specifically, in the conventional repeater system, a predetermined sub-CPU that grasps the current state including the failure of the relay module is integrally formed in the relay module controller, and the sub-CPU of the relay module controller having such a structure Since it is specialized for one relay module, when the relay module is upgraded or replaced, it is inevitable to replace the upgraded sub-CPU accordingly, so that both the sub-CPU and the main controller integrated with the relay module controller are inevitable. There was a problem that needs to be replaced.

In order to solve the above problems, the present invention, by forming a main controller on a circuit board separate from the relay module controller, by allowing the function of the sub-CPU of the relay module controller to be integrated in the CPU of the main controller, It is possible to effectively cope with the upgrade of the repeater system according to the upgrade and replacement of the relay module.

In order to achieve the above object, the present invention includes a relay module controller equipped with at least one relay module and communicating a signal transmitted from a predetermined main controller with the relay module; A main controller configured to control operations of the relay module mounted on the relay module controller and the relay module controller; A relay module monitoring device comprising: the main controller provides a relay module monitoring device in a repeater system configured on a circuit board separate from the relay module controller device.

The information transmitted to control the relay module from the main controller may include predetermined identification information for identifying the at least one relay module.

Therefore, the control signal for the at least one relay module and the response to the control signal are identified by the identification information, thereby enabling proper control operation.

In addition, a signal communicated through each pin of the parallel communication device may transmit a signal relating to a predetermined control state individually assigned to each pin, and further, by designating each pin to transmit a TX / RX signal. Certain data may be communicated.

In addition, the communication between the relay module controller and the relay module is preferably performed by a predetermined standardized communication protocol. Therefore, even when the relay module is upgraded or replaced, by using a standardized protocol between the relay module controller and the main controller and the relay module, an operation such as conversion of additional protocols is unnecessary, thus making it compatible with various relay modules. It becomes possible.
