Field of the Invention The present invention relates to a method for notifying the occurrence of a state change between a supervisory control device and base stations such as a plurality of portable terminals, and obtaining and obtaining the state of each base station. The present invention relates to a system for controlling each base station. 2. Description of the Related Art FIG. 3 shows an example of the configuration of a conventional base station monitoring and control system. The conventional base station monitoring and control system is divided into a monitoring system side and each base station side. The monitoring system includes a monitoring console (personal computer) 1 that monitors the status of each base station. Each base station comprises an amplifying device 2 for amplifying an input signal at each base station, and a modulation / demodulation device 3 for modulating / demodulating a signal input to the amplifying device 2. The amplifying device 2 includes a plurality of amplifiers 21 and a device cooling fan 22.

One port of the modem 3 corresponding to the state change is controlled (for example, from OFF to ON). The modulation / demodulation device 3 controls the device cooling FAN 2 by the above control.
2 recognizes that the state has changed, and performs corresponding signal conversion. A cooling fan FAN 22 is connected to the monitoring console 1 via the dedicated line 7.
Is notified that the status has changed. The monitoring console 1 determines which base station and which port the signal is coming from, and determines the device cooling F of the base station.
The state change of the AN 22 is displayed on the screen of the monitoring console 1. [0003] In such a conventional base station monitoring and control system, when there is a new development of a constituent unit or the like, the notification content may change from the state of the existing device. That is, a request for addition or change occurs, and as a result, a sufficient port corresponding to each component unit cannot be prepared. In addition, existing conversion units must be used together after conversion.Therefore, there are ports that will not be needed in the future but must be kept at the time of equipment change. There are limits to continuing. [0004] An object of the present invention is to provide a system in which, when a status change of a base station cannot be dealt with only by an existing port notification due to a new development of a constituent unit or the like, only a change in status of one of the units is achieved with a small number of ports. It is another object of the present invention to provide a base station monitoring and control system that can notify a user via a dedicated line, obtain detailed information by another system, and display the information on a screen in a manner that is easy to understand. [0005] In order to achieve this object, a portable terminal base station monitoring and control system according to the present invention comprises an amplifying apparatus having a plurality of monitored parts provided in a plurality of base stations.

The monitoring console is transmitted to the monitoring console via the device and the dedicated line, and the monitoring control device is configured to control the amplification device based on the monitoring data. Configuration. FIG. 1 shows an example of the configuration of a base station monitoring and control system according to the present invention. The monitoring system side of the base station monitoring and control system of the present invention obtains information such as the status of the amplification device 2 in addition to the monitoring console 1 (personal computer) that monitors the status of each base station, and operates the amplification device by remote operation. And a monitor / control device (personal computer) 4 dedicated to the amplification device having a function of performing reset control on. In addition, each base station side includes, as an additional component of the amplifying device 2, in addition to the amplifying device 2 that amplifies an input signal at each base station and the modem device 3 that modulates and demodulates a signal input to the amplifying device 2. A monitoring and control panel having a function of monitoring the states (normal operation, occurrence of alarms, etc.) of the plurality of amplifiers 21 and the cooling fan FAN 22 and notifying the modem 3 when a change in state occurs in any of the units. There are 23. In the configuration example of the present invention, between the monitoring system side and each base station, in addition to the dedicated line (eg, optical fiber cable) 7 used in the prior art, an amplifying device dedicated monitoring control device (personal computer) 4 Since the general telephone line 8 is used between the monitoring control panel 23 and each base station, the modem 5 on the monitoring system side is used.
And the modem 6 of each base station are also included in the components. Further, the monitoring control panel 23 has a function for performing communication by a modem. In the prior art, a number of signal lines (ports) for notifying the modulator / demodulator 3 of a state change from each of the constituent units of the amplifier 2 are output. The information of each component unit of the device 2 is acquired, and if any one of them has a status change, one signal line (port) is controlled (eg, OFF →
ON) alone notifies that a state change has occurred. FIG. 2 shows an example of a screen display for acquiring information by the monitoring device 4 dedicated to the amplifier, and the "name" column displays the base stations A, B, C,. The "Status" column is normal, or "Not acquired", "Connection failed", "Retrying", "Implementation mismatch", "Alarm"
Indicates the state of the base station in the abnormal state. Hereinafter, “FAN” indicates the state of the cooling fan, and “1”, “2”,..., “12” are numbers indicating the types of alarms exemplified in the “alarm details” at the bottom. “SV” indicates a supply voltage ((Supply Voltage), and “Poll” indicates whether or not polling (ON) (O
FF). In the display column, “○” indicates normal, and “△” indicates mounting mismatch, respectively.
“01” and “02” indicate the type of alarm. The type of the alarm is determined as needed, and for example, the following types can be adopted. a) Gain fluctuation: This alarm is activated when the level difference between the input power and the output power of the amplifier is equal to or more than a certain value. b) Power failure: This alarm is triggered when the voltage of the power supplied to the amplifier drops. c) IM failure: Distortion control of the amplifier is performed for a certain time (for example, 6
If this is not completed within 0 seconds), this alarm will be activated. d) Over output: This alarm is activated when the output power from the amplifier exceeds a certain value. e) Temperature abnormality: This alarm is activated when the temperature inside the amplifier exceeds a certain value. f) Distortion compensation control failure: PLL (Phase Lock) inside the amplifier
Loop) When the frequency synthesizer is unlocked,
This alarm is triggered. g) FAN failure device If the cooling fan is operating at a specified rotation speed or less, or is not rotating, this alarm is issued. h) FAN POWER OFF When the amplifier cooling power is on and the cooling fan is off,
This alarm is triggered. i) USP alarm This alarm is issued when either of the two power supplies supplied to the DC / AC converter is NG. Next, the operation of notifying the occurrence of a state change of the base station constituting unit and the operation of acquiring information such as the state of the base station in the present invention will be described. The operation when a state change (normal → abnormal) occurs in the device cooling FAN 22 is as follows. The monitoring control panel 23 recognizes that this state change has occurred. 1 corresponding to any state change occurrence in the amplification device 2
One port 3-1 is controlled (for example, OFF → ON). The modem 3 recognizes that any state change has occurred in the amplifier 2 by the above control. The process enters a process of notifying the monitoring console 1 via the dedicated line 7 that any state change has occurred in the amplifier 2. In the console 1, which signal line (port) of which base station
The process enters a process of recognizing that any state change has occurred in the amplification device 2 of the base station by determining whether the signal is a signal from the base station. The monitor and control unit 4 dedicated to the amplifier connects to the monitor and control panel 23 via the modem 5 and the modem 6 of the base station. The monitoring control panel 23 acquires detailed information of the amplification device 2 of the base station by data transmission / reception (data communication), and displays the obtained result on the screen of the amplification device dedicated monitoring control device 4. If necessary, reset control is performed on the amplification device 2 of the base station by the monitoring and control device 4 dedicated to the amplification device. An example of reset control for the amplifier will be described. B) For the amplifier of the base station where the alarm is occurring,
In some cases, resetting may be attempted to return to normal, and the state may be temporarily observed, so that this operation is prepared. B) Based on the monitoring data obtained through the public line, the originating base station, the originating amplification device number, and the alarm content can be grasped. C) For the base station, by selecting a device to be reset by the monitoring control device and executing the process,
Signals are exchanged with the monitoring control panel of the base station via the public line. D) In the monitoring control panel, the amplifier is reset by controlling the reset signal of the amplifier from Low to High to Low in accordance with the signal (reset request) received from the monitoring and control device. E) However, if a device that does not generate an alarm is selected as a device to be reset, it is determined on the monitoring control panel side, and the reset signal is not controlled so that there is no problem in base station operation. As described above, according to the present invention, the following effects can be obtained. Since a single port for state change detection for a newly-developed amplifier is sufficient, the scale of changes relating to the state change monitoring of the modem 3 and the monitor 1 can be reduced. Since the system can be operated with a configuration in which a new monitoring control device is added while the conventional monitoring system is maintained, an amplification device having a conventional configuration and a newly created amplification device can be mixed. Therefore, since there is no need to renew the system in a short time, capital investment can be suppressed. The visualization of information acquisition by the new supervisory control unit makes it easy to grasp the state of the amplifier.
