Embodiments of the present invention will be described below in detail. FIG. 1 is a block diagram showing a configuration example of the operation panel device according to the present invention. In FIG. 1, the radio base station 3 and the operation control panel device 7 are connected to the central control device 6. The radio base station 3 includes a base station control board 1 and a base station control board 2. The operation control panel device 7 includes a display panel 8, a control unit 9 and an operable number flag 10, an operation base station control board number flag 11, an operation state flag 12 of the base station control board 1, and an operation state of the base station control board 2. Flag 1
3. There is a monitoring timer 14 for the base station control board 1 and a monitoring timer 15 for the base station control board 2. Operable number flag 10
Represents the number of base station control boards operable in the wireless base station, including those currently in use and those on standby. The operation base station control board number flag 11 indicates the number of the base station control board that is currently connected to the operation control panel device and is in a state that can be monitored and controlled. The operation status flag 12 of the base station control board 1 and the operation status flag 13 of the base station control board 2 are flags indicating whether the base station control board is in use, on standby, or inoperable. The train station 4 uses the transceiver 5 (T / RX) of one of the base station control boards 1 and 2 from the antenna 5 of the wireless base station 3 to make a call via the central control device 6. A communication line from the transceiver (T / RX) of the base station control boards 1 and 2 to the central control device 6 is transmitted from the control section of the base station control boards 1 and 2 via the central control device 6 to the operation control panel. A control line extends to the control unit of the device 7. In FIG. 1, independent lines are respectively drawn from the base station control boards 1 and 2, but one line can be shared by both control units.

FIG. 2 is an example of an external view of the display panel 8 of the operation control panel device. In this example, a case where there are two base station control boards is shown. The handset 21 has a normal telephone function together with the dial key 23. In the display lamp section 22, the upper three lamps are T-SQ lamps indicating the state of the radio wave received by the base station control board 1. The next stage is a lamp indicating the radio wave state of the base station control board 2. The third row is a display section using seven-segment light-emitting diodes, which is not directly related to the present invention, but displays a device number or the like as necessary. On the fourth row, from the left, READY and alarm lamps ALM1 and ALM2 are arranged. RE
The ADY lamp is a lamp indicating whether the operation control panel device 7 is operating normally. ALM1 and ALM2 are
Lights when the base station control boards 1 and 2 are inoperable. When both lamps are turned on at the same time, the active and standby base station control boards of the wireless base station are in an inoperative state, the wireless base station is not functioning in an emergency state, and an emergency buzzer (not shown) is activated. Let it ring.

The operation status switch lamps 24 indicate whether the base station control board is currently in operation or on standby, and there are two corresponding to the base station control boards 1 and 2. The lit base station control board is in use, and if turned off, it is on standby. During standby, if the base station control board becomes inoperable, the corresponding ALM lamp of the display lamp unit 22 is turned on. The operation state switch lamp 25 also corresponds to the base station control boards 1 and 2, and indicates that the lit base station control board is in a state where it can be controlled under the operation of the operation control panel device 7. The operation state switch lamp 24 and the operation state switch lamp 25 are push-button switches together with the state display by the lamps, and when pressed, can control the base station control board. That is, for example, when the base station control board 1 is to be used, the OPI of the operation state switch lamp 25 is pressed to make the base station control board 1 operable from the operation control panel device 7 and the operation state switch lamp I This is done by pressing. Although not directly related to the present invention, the lower switch 26 controls the base station control board and is used for selecting a radio channel used by the radio base station. Of course, the base station control board to be controlled is the base station control board selected by the operation state switch lamp 25.

A mode change command to work, a mode change command to standby, and a periodic command are sent from the base station control boards 1 and 2 to the operation control panel device 7 using a control line. The mode change command to the active mode is sent when the base station control board that has been waiting until now becomes active, and the mode change command to the standby mode is issued when the base station control board that is currently active is in standby mode. Sent when becomes. Working refers to the state of the radio base station used for calls with the train station. Standby means that it is not used for calls with the train station,
This is a state in which the active base station control board is on standby as a backup when a failure occurs. In both the active state and the standby state, a periodic command is transmitted to the operation control panel device 7 at regular intervals to notify that each base station control board is operating or operable. These commands include a command code indicating the content of the command and a base station control board number. The command to change to active or standby is automatically detected by the radio base station when the base station control board has failed, and is automatically transmitted by automatic switching. It is transmitted from the base station control board when the state of the base station control board is changed or when the state is changed by the operation control panel device.

FIGS. 3, 4, 5, 6, and 7 show a control flow of the present invention. Hereinafter, the operation will be described in detail based on the control flow. The operation control panel device 7 constantly checks whether a mode change command for working, a mode change command for standby, and a regular command come (STEPs 30, 32, and 34).
First, when a change command to the working is received (YE in STEP30)
S), the active mode change processing (STEP 31) is performed. Details are shown in FIG. As an example, from the base station control board 1 of FIG.
When a mode change command to work is received, the base station control board number 1 included in the change command to work is registered in the operation base station control board number flag 11 of FIG. 1 and the flag is updated (STEP 41). . Next, the lamp I of the operation state switch lamp 24 corresponding to the base station control board 1 is turned on (STEP 42), and the lamp OPI of the operation state switch lamp 25 corresponding to the base station control board 1 is turned on (step 4).
3) The operation control panel device 7 can monitor and control the base station control board 1. Next, the operation status flag 12 of the base station control board 1 is set to working (STEP 44), and the monitoring timer 14 of the base station control board 1 is started (STEP 45). Next, it is checked whether another base station control board is operable (ST
EP46). Here, the state of the base station control board 2 is viewed from the operation status flag of the base station control board 2. If the base station control board 2 is not operating (NO in STEP 46), STEP 31 ends and the state becomes STEP 32. If the operation is in progress (YES in STEP 46), the lamps II and OPII of the operation state switch lamp 24 and the operation state switch lamp 25 corresponding to the base station control board 2 are turned off (STEP 46).
47, 48), the operation control flag 13 of the base station control board 2
(STEP 49), the monitoring timer 15 of the base station control board 2 is started (STEP 50), and STEP 31 ends.
When the monitoring timer 15 is started, its value is reset to 0.

If STEP 31 ends or if the change command to the active mode is not received in STEP 30 (NO in STEP 30), it is determined whether the mode change command to standby is received (STEP 32). If the change command to standby is received (YES in STEP32),
A standby mode change process is performed (STEP 33). The details are shown in FIG. For example, when a change command to the standby mode is received from the base station control board 2, the operation state flag 13 of the base station control board 2 is set to the standby state (STEP 51), and the base station control board 2
(Step 52), the operation status switch lamp 24 of the lamp II corresponding to the base station control board 2
Is turned off (STEP 53). STEP33 ends or STEP
32, if the change command to standby is not received (STEP 32
NO), it is checked whether a periodic command is received (STEP 34). If a periodic command is received (YES in STEP 34), the monitoring timer of the base station control board is restarted (STEP 35), and the ST
It proceeds to the timer monitoring process of EP36. If the command is not a regular command in STEP 34 (NO in STEP 34), a timer monitoring process is directly performed (STEP 36). 6 and 7 show details of the timer monitoring process.

In FIG. 6, first, the value of the operable number flag 10 is stored and stored in a memory. Here, it is assumed that the data is stored in the area A (STEP 60). Next, the monitoring timer 14 of the base station control board 1 is checked to see if it is running (STEP 61).
If it is not running (NO in STEP 61), the process proceeds to STEP 71 in FIG. If the monitoring timer 14 is running (YE in STEP 61)
S), it is checked whether a timeout has occurred (STEP 62). The monitoring timer is always started when the operation status flags 12 and 13 indicate that the base station control boards 1 and 2 are operating or waiting. The value of the monitoring timer is reset to 0 when activated, and thereafter, the value is increased by the automatic timer. If the value exceeds a predetermined value, it is determined that a timeout has occurred. If the timeout has not occurred in STEP62 (in STEP62,
NO), proceeding to STEP 71 in FIG. If a timeout has occurred (YES in STEP 62), 1 is subtracted from the value of the operable number flag 10 (STEP 63), and ALM1 of the display lamp unit 22 is subtracted.
Is turned on (STEP 64), and whether the base station control board 1 is currently in use is checked by the operation status flag 12 of the base station control board 1 (STEP 65). If it is not in use (NO in STEP 65), the process proceeds to STEP 71 in FIG. If it is currently in use (YES in STEP 65), the operation status switch lamp 2
The I and OPI corresponding to the base station control board 1 of 4 and the operation state switch lamp 25, and the T-SQ lamp of the base station control board 1 of the display lamp section 22 are turned off (STEP 66). Next, the operation status flag 12 of the base station control board 1 is deactivated (STEP 67), and the operation status flag 1 of the base station control board 2 is turned off.
3 and checks whether the base station control board 2 is on standby (STEP 68). If not waiting (N in STEP68
O), proceed to STEP 71 in FIG. If it is on standby, the base station control board 2 is made active (STEP 69). To make the base station control board 2 active, an active request command is sent to the base station control board 2. The base station control board 2 that has received the working request command switches to the working mode and returns the working mode change command to the operation control panel device 7.
The data is received in STEP 30, and the active mode change processing (STEP 31) is performed.

Next, the monitoring timer 15 of the base station control board 2
To see if it is running (STEP 71). If it is not running (NO in STEP 71), the process proceeds to STEP 80. If the monitoring timer is running (YES in STEP 71), it is checked whether a timeout has occurred (STEP 72). If not time out (STEP
(NO at 72), proceed to STEP80. If a timeout has occurred (YES in STEP 72), 1 is subtracted from the value of the operable number flag 10 (STEP 73), and ALM2 of the display lamp unit 22 is subtracted.
Is turned on (STEP 74), and whether the base station control board 2 is currently in use is checked by the operation status flag 13 of the base station control board 2 (STEP 75). If it is not in use (NO in STEP75), the process proceeds to STEP80. If it is currently in use (YES in STEP 75), II and OPII corresponding to the base station control board 2 of the operation state switch lamp 24 and the operation state switch lamp 25, and T of the base station control board 2 of the display lamp unit 22
-Turn off the SQ lamp (STEP 76). Next, the operation status flag 13 of the base station control board 2 is deactivated (STEP 7).
7), looking at the operation state flag 12 of the base station control board 1,
Check whether the base station control board 1 is on standby (ST
EP78). If not waiting (NO in STEP78), STEP8
Go to 0. If it is on standby, the base station control board 1 is made active (STEP 79).

When the timers of the base station control board 1 and the base station control board 2 are monitored, the value of the operable number flag 10 and A
The old operable number stored in the area is compared with the value (STEP 80). If they are the same (YE in STEP80)
S), this flow ends. If they are different (S
(NO in TEP80), it is checked whether the value of the operable number flag 10 is zero (STEP81). If the value is not zero (ST
If NO in EP81), this flow ends. If the value is zero (YES in STEP 81), since all the base station control boards 1 and 2 are inoperative, an alarm such as an emergency buzzer is sounded and the maintenance person is notified (STEP 82).

In the flow of FIG. 3, the mode change command and the periodical command are targeted as commands, but the base station control board also issues other commands for transmitting the state of the received radio wave at the base station control board, Although there is a response command to the setting of the wireless channel on the base station control board in the lower switch 26, it is omitted because it is not directly related to the control of the present invention. In the flow of FIG. 3, a loop is formed and a mode change command and a regular command come (STEP 30,
32, 34) and the timer monitoring process (STEP 36) is described as being performed constantly, but it is also possible to perform it in an interrupt format. That is, when a command is received, an interrupt occurs, and the command receiving process operates (STEP 30 to ST 30).
It is also possible to adopt a method in which a timer monitoring process (STEP 36) is executed by a timer interrupt started at a predetermined time interval (EP35).

Both the active mode change processing in FIG. 4 and the standby mode change processing in FIG. 5 are mode change processing in the active or standby base station control board. It is not the mode change processing from. In order to make the inactive base station control board active, it is put on standby once and then made active. To put the inactive base station control board in the standby state, replace or repair the inactive base station control board, send a standby request command from the operation control panel device, and receive the received base station control board. Sends a standby response command. The operation control panel device that has received the standby response command changes the operation state flag of the corresponding base station control board to standby, adds 1 to the value of the operable number flag 10, turns off the alarm lamp, and sets the monitoring timer. to start.

As described above in detail, according to the present invention, two base station control boards can be monitored and controlled by one operation control panel device. There is no need to use two units, and three or more units can be used. In this case, additional flags required for each base station control board such as an operation state flag and a monitoring timer provided on the operation control panel device 7 are provided, and a lamp or switch lamp corresponding to the base station control board provided on the display panel 22 is provided. It is necessary to provide for each base station control board.

The present invention has the following advantages. (1) Even when there are a plurality of base station control boards in the wireless base station, it is possible to determine on the display panel whether all the base station control boards are in operation, standby, or non-operation. (2) The number of the base station control board that is currently selected and connected to the operation control panel device and can be monitored and controlled can be displayed on the display panel. (3) The operation control panel device automatically responds to changes during use or standby of the base station control board, and the related lamps can be turned on and off automatically.
