DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio base station controller for train radio.

[0002]

2. Description of the Related Art A block diagram of a conventional radio base station for train radio is shown in FIG. The radio base station 201 has a radio unit 211 for the first operation channel and a radio control unit (C-CONT).
207, a radio unit 212 for the operation channel of the second system, a radio control unit 208, a radio unit 213 for the maintenance channel of the first system, a radio control unit (M-CONT) 209, and a radio unit 214 for the maintenance channel of the second system. There is a wireless control unit 210, and the power supply is 1
Each device of the system is supplied with power from the power supply of the first system, and each device of the second system is supplied with power from the power supply of the second system. When one of the devices of the system 1 and the system 2 is operating and being used for an operation call and a maintenance call, the other is in a state of performing only monitoring as a spare. An operating device is called active, and a device that only monitors is called standby. The first-system wireless controller 207 and the second-system wireless controller 208 are directly connected by a control line 231, and the first-system wireless controller 209 and the second-system wireless controller 210 are directly connected by a control line 232. You can monitor the status of each other. Now, it is assumed that the first-system wireless control unit 207 and the wireless unit 211 are in operation, and the second-system wireless control unit 208 and the wireless unit 212 are on standby.
When the wireless control unit 208 detects this abnormality through the line 231, the wireless control unit 208 and the wireless unit 212 are put into operation, and the wireless control unit 207 and the wireless unit 211 are put on standby. Also, the wireless control unit 207 which is set as the active system
Detects an abnormality in its own device or the wireless unit 211, the wireless control unit 207 notifies the abnormality to the standby wireless control unit 208, and the system is switched. This is called system switching. This system switching is performed in the same manner even when the maintenance channel is active / standby. Then, basically, the apparatus in which the abnormality has occurred holds the standby state. The radio control units 207 and 208 for the operation channel and the radio control units 209 and 210 for the maintenance channel are independent from each other. Even if the control unit 208 and the radio unit 212 are in service, the maintenance channel is maintained in the first radio control unit 209.
And the wireless unit 213 may be in use.

[0003] The operating channels are the radio control units 207 and 208.
Is connected to the central control unit (CCE) 218, and the maintenance channel is connected from the radio control units 209 and 210 to the telephone connection unit (TIU) 219, so that it is possible to talk on the active operation channel and the maintenance channel, respectively. It has become. The base station control panel (BSCP) 204, which operates the main functions of the radio base station, includes radio control units 207 and 20.
8, 209 and 210, but only the operation of the active wireless control unit is possible. The main console (ICP) 220 installed along the train track and the operating console (YCP) 221 installed in the operating field are also connected to the wireless control units 207 and 208. It is possible to operate only the working system in the working channel wireless control unit.

One of the problems of the conventional maintenance device is that the base station operation panel 204 has two radio control units 207 and 20 for the operation channel and the maintenance channel of the first and second systems.
8, 209 and 210, and a main line console 220 is connected to both radio units 207 and 208. These consoles 204 and console 220 are used for the current operation channel and maintenance channel. Therefore, the operation from the operation panel 204 and the operation console 220 can be performed only for the active system, and the operation of the standby device cannot be performed. For this reason, when a device in the wireless base station fails, the failed device is placed in a standby state, and the failed device is replaced, but the operation of the replaced device is checked from the operation panel or console as described above. It was necessary to check the operation after suspending the operation. If the operation could not be interrupted, the operation was confirmed after the operation was completed.

[0005] Further, since the radio control unit of the operation channel and the radio control unit of the maintenance channel operate independently, for example, if a failure occurs in the radio unit 211 of the working first operation channel, the radio control unit is in standby until now. The wireless unit 212 and the wireless control unit 208 of the second operation channel become active, but the wireless unit and the wireless control unit for the maintenance channel remain active while the wireless control unit 209 and the wireless unit 213 of the first maintenance channel remain active. It is.
However, in the power supply system, the system 1 and the system 2 are independent of each other, so that both the system 1 and the system 2 supply power to the working system. For this reason, when it is desired to turn off the power for repair or the like, there has been a case in which the power for the active system must be turned off regardless of which power is turned off.
