Abstract

PROBLEM TO BE SOLVED: To provide a monitoring controller which never causes a system down when a monitoring control panel has its on fault. SOLUTION: If a bus interface panel BINT15-1 has a fault, a message signal is sent to a central control panel CP11-1. When the fault is recognized, the panel CP11-1 switches the control of a front panel to a bus interface panel BINT15-2. The panel BINT15-2 uses the slot state information on every shelf stored in a standby area instead of the data stored in a RAM and carries on the monitoring and control of a system. The panel BINT15-1 serves as a standby panel. At the same time, the addresses of the standby area and the RAM area are dynamically switched to each other. A local memory 15a-1 of the panel BINT15-1 and a local memory 15a-2 of the panel BINT15-2 share a memory area which stores the state information data.

Is a standby system for the bus interface panel BINT15-1.

The active BINT 15-1 is provided for each mounting panel stored in the slot number order (# 0 to $ 1F) in the area of the shelf number 0 in the panel control table in the storage area of the global memory 14a-1. The status change is monitored in a slot number order (# 0 to $ 1F) for a predetermined time, for example, every 2 ms, and each panel status is stored in the corresponding storage area in the panel control table. When the processing of shelf number 0 is completed,
Subsequently, the same processing is repeated for shelf numbers 1 to n. This operation is performed for all panels.

For example, when the operation system is the bus interface panel BINT15-1, the bus interface panel BINT15-1 is the global memory 14a-1.
The old panel state information corresponding to shelf number 0 and slot number $ 0 is extracted from the old state table shown in FIG. Next, from the area of the panel control table of the global memory 14-1, the bus interface panel BI

The status change of each slot mounted on the corresponding shelf is stored.

At the same time, the central control panel CP11-
1, the same data as the status information data of each shelf slot stored in the local memory 15a-1 is stored in the corresponding area of the local memory 15a-2 of the spare bus interface panel shown in FIG. Will be overwritten. Here, in FIG. 3, the active local memory 15a-1 corresponds to the dual port RAM area, and the local memory 15a-2 corresponds to the standby area.

At this time, the bus interface panel BI
The NT 15-2 uses the status information of each shelf slot stored in the spare area having the same data instead of the data stored in the dual port RAM, and continues monitoring and controlling the system. At this point, the bus interface panel BINT15-1 becomes a standby system. That is, when the control subject is switched, the spare area becomes a dual-port RAM area, and the dual-port RAM area is dynamically switched to the spare area.

For this purpose, the bus interface panel B

It is mounted on a card in another slot.

That is, when the area segment to be accessed by each bus interface panel is dynamically switched depending on the operation / standby state, both storage areas can be accessed. While the bus interface panel BINT 15-1 is operating, when the bus interface panel BINT 15-1 writes the current state of each shelf to the dual port RAM, the same is applied to the standby system area which is the local memory 14a-2 area of the standby system. The data is written so that the information data of the two always match.

At this time, the standby bus interface panel BINT15-2 does not monitor the status of each card mounted in the slot. While the bus interface panel BINT15-1 is operating normally, the bus interface panel BINT15-2 monitors the port in the panel state for detecting its own operation state, standby state, closed state, and the like, and confirms normal operation. The watchdog timer reset process that periodically checks the operation status is repeatedly performed.

According to the present invention, there is provided a monitoring and control apparatus for monitoring and controlling a device installed in a radio base station for controlling a radio channel between a radio base station and a mobile radio station. A plurality of panels divided and mounted on a shelf inside the device, and a first monitoring panel for monitoring the operating states of the plurality of panels and the operating state of the panel itself,
A second monitoring panel that monitors the operating states of the plurality of panels and its own operating state; and a control unit that controls the plurality of panels, the first monitoring panel, and the second monitoring panel. When the controller detects a failure in either the first monitoring panel or the second monitoring panel, the control panel activates the other monitoring panel. Therefore, even if the card is suddenly switched from the active card to the spare card, all the cards operated by the spare card hold the same state in real time, and there is no change after switching the control system compared to before the switch. The effect is that the system can be operated with no monitoring and control.

According to the present invention, in the monitoring and control device according to claim 1 or 2, data stored in the first storage means and data stored in the second storage means are stored. Since the first monitoring panel and the second monitoring panel each control the storage means so that the data always has the same contents, the data stored in the active and standby memories are the same. Even if the card is suddenly switched from the active to the spare, the data on the operation information of all the cards in each operating shelf is held in the spare card in the same way. And the system can be operated in the same state after switching as before switching.
