Field of the Invention The present invention relates to a system of a cable television (CAV) (CATV), and in particular, in an unmanned base station (RT) of an optical cable television, an unmanned base station operates regardless of various environmental changes of attention and automatically according to a set condition. The present invention relates to an unmanned base station (RT) having an unmanned base station automatic control device that is adjusted to remotely transmit / receive state information and a control method thereof.

In general, a cable television system is composed of a network management unit, a distribution center, and a subscriber device, and a passive optical subscriber network (PON) in which 155 Mbps optical signals transmitted from the distribution center to the subscriber device are simultaneously transmitted to three subscribers under the control of the network management unit. : Provides service with Possive Optic Network structure.

The unmanned base station is to control the device to send a variety of information to the host, under the control of the host to operate in conjunction with the remote maintenance center to optimize the system.

However, since the unmanned base station is poor in various environments and no human can reside, in order to transmit the repair history to the network management unit of the optical cable television system when there is an error in the subscriber device, a separate document on the repair history must be prepared or repaired. There was a problem that a separate person is needed to collect historical data.

The present invention is to solve such a conventional problem by adding an automatic control device to the unmanned base station, so that it is possible to remotely transmit and receive status information regardless of environmental changes, and to receive appropriate measures for the alarm history. It is characterized by.

In other words, the values collected from each sensor are converted by the analog / digital converter, the appropriate action is taken according to the set conditions, and the alarm details are sent to the host for action.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

The present invention will be described with reference to FIG. 1 which is a block diagram of an unmanned base station to which an unmanned base station automatic control apparatus is added.

The operation of the unmanned base station automatic control apparatus of the present invention configured as described above is as follows.

The automatic control device in the unmanned base station changes the analog values of temperature and humidity in the analog / digital converter 5 into digital values, stores various error values generated after self-test in the buffer 6, and in the controller 7 Controlled state values are inputted from the microprocessor 11 in the unmanned base station through the parallel processing interface unit 8 to divide various types of information into emergency, major, and general alarms, and the divided alarms are generated at this time. It transmits the information to the host through the Ethernet interface (3), and receives the information of the host through the Ethernet interface (3) and changes the set value and maintains the proper system. Testing and fault handling are possible.

The operation of the microprocessor in the automatic base station automatic control apparatus configured and operated as described above will be described in detail with reference to FIG.

First, the operation of the microprocessor is started by the reset circuit, and the first step (S1) for vaporizing each port; A second step (S2) of determining whether there is a remote control command of the host or a self test after the vaporization is completed in the first step (S1); A third step (S3) of inputting command information of a host if there is a remote control command after the determination of the second step (S2); In the third step (S3), it is determined whether the command content of the host is a setting value change request or various state information requests of the unmanned base station, and if the setting value change request is changed, the setting value is changed, and the status information request, temperature, A fourth step S4 of transmitting a state of humidity, voltage, etc .; If the self test after the determination of the second step (S2), the value of each port is input (S5-1), and the input value is read and compared with the set value of the unmanned base station to determine whether to input temperature information or state information request.
