[Problems to be solved by the invention]
However, in this type of communication control device, it is necessary to notify the maintenance person at the same time as the end of the high impedance state that the extraction operation is disabled. For this reason, it takes a little time for the maintenance person to recognize the state and perform the operation, and even if it is in the high impedance state at the time of confirming the lamp state, the high impedance is required until the card removal operation is started. The state may end. If the card is removed after completion of such a high-impedance state, the card may be physically damaged or the service being operated may be damaged. There is a need to prevent.
[0005]
In addition, it is necessary to have unified control for lighting of all lamps. However, lighting at the same time as other lamps directly connected to hardware such as transmission lamps and reception lamps may increase circuit design and increase costs. There is.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0028]
FIG. 1 is a block diagram showing a main configuration of a communication control apparatus according to Embodiment 1 of the present invention. In FIG. 1, in the communication control device 100, an explanation target card 110 that is an object and other cards 120, 130, and 140 are connected to a common bus 150 by a bidirectional bus.
[0029]
The explanation target card 110 is connected to the common bus 150 via a bidirectional bus and controls the common bus 150, and the explanation target card 110 is connected to the common bus control section 111 via a bidirectional bus. A card control unit (object control means) 112 for controlling the display, a display operation unit (operation means) 114 for performing a display (notification) operation connected to the card control unit 112 via a bidirectional bus, and a bus connection to the card control unit 112. And a timer unit (time setting means) 113 for setting a predetermined time.
[0030]
With this configuration, when the common bus 150 is controlled to the explanation target card 110 connected to the common bus 150, the common bus 150 is connected to the explanation target card 110. When there is an erroneous operation, a predetermined time is set by the common bus 150 and a notification operation is performed, and the maintenance person turns on the main lamp without removing the card that is the explanation target card 110 after completion of the high impedance state. It is possible to quickly notify the maintenance person of the erroneous operation.
[0031]
The operation of the communication control apparatus 100 configured as described above will be described. First, when a reset switch (not shown) of the explanation target card 110 is pressed, the card control unit 112 is notified of the reset switch being pressed.
[0032]
The card control unit 112 starts the high impedance state by instructing the common bus control unit 111 to close the common bus 150. At the same time, the card control unit 112 sets a timer for, for example, 9 seconds for the timer unit 113.
[0033]
When the card control unit 112 receives a notification of the completion of the blocking process from the common bus control unit 111, the card control unit 112 instructs the display operation unit 114 to turn on all the lamps. At the same time, a timer for 200 milliseconds is set for the timer unit 113. After 200 milliseconds have elapsed, the timer unit 113 notifies the card control unit 112 that the timer has expired, and instructs the card control unit 112 to turn off all the lamps.
[0034]
When the 9-second timer expires, the timer unit 113 notifies the card control unit 112 that the timer has expired. The card control unit 112 instructs the display operation unit 114 to turn on all the lamps. At the same time, the card control unit 112 sets a one-second timer for the timer unit 113.
[0035]
The timer unit 113 notifies the card control unit 112 that the timer has expired after 1 second. The card control unit 112 instructs the display operation unit 114 to turn off all the lamps. At the same time, the common bus control unit 111 is instructed to release the block of the common bus 150, and the high impedance state is terminated.
[0036]
Thereafter, the card control unit 112 performs control so that the card to be described is incorporated into the system operation after the initialization of the explanation target card 110 again. As described above, it is possible to notify the maintenance person one second before the start and end of the high impedance state.
[0037]
The timer unit 113 has appropriate setting times of 200 milliseconds, 1 second, and 9 seconds as the setting time, but it goes without saying that other values may be used. It is also possible to set the lighting time of all lamps that indicate the start of high impedance and the lighting time of all lamps that announce the end to the same time, but it is better to start or end with some difference in time This is effective because it is possible to further prevent such a misrecognition of the maintenance person.
[0038]
Further, the relationship between the time set for the timer unit 113 and other processing is assumed to be simultaneous for convenience in the description so far, but it is not necessary to be simultaneous in a strict sense, and the setting time of the timer unit 113 is 2000 mm. Needless to say, the processing may be changed before and after the second, 1 second, and 9 seconds.
[0039]
In this embodiment, all lamps are turned off at the end of the high impedance. However, after the maintenance person is informed of the end of the high impedance, if the time sufficient for the maintenance person to recognize has passed, It goes without saying that the lamp can be turned off before or after the high impedance ends.
[0040]
Furthermore, in this embodiment, all lamps are turned on, but it is sufficient that the maintenance person knows that the high-impedance state will be terminated, and it is sufficient that all lamps are turned on and off. It is also conceivable to turn the lamp on or off. It is also possible to use flashing lamps.
[0041]
As described above, in this embodiment, the end of high impedance can be displayed in advance on the front of the card. Also, when removing the card, the maintenance person can recognize the start and end of the high-impedance state, and a communication control device excellent in preventing erroneous operation can be provided.
[0042]
The communication control apparatus of the above embodiment can be applied to a base station communication control apparatus used for a base station apparatus, a mobile station communication control apparatus used for a mobile station apparatus, or a control station communication control apparatus used for a control station apparatus.
[0043]
