Abstract

PURPOSE:To able to communicate a signal with a communication request simultaneously independently of the operating system or the nonoperating system by connecting duplicated maintenance operation management equipments and a centralized management equipment via a time division multiplexer. CONSTITUTION:When a time division multiplexer 103 detects a carrier signal of a maintenance operation management equipment 104, a signal with a form shown in figure B is sent to a communication control section 200 in a centralized management equipment 102 and the control section 200 uses a signal format with a form shown in figure A to inform it to a state management section 201 in the equipment 102. The management section 201 analyzing the signal sends a status notice request to the management equipment 104 through the control section 200 and the equipment 104 sends a reply signal information its own operating state (whether in operation or not in operation). The similar transmission and reception is applied to the management equipment 105 and then the management section 201 recognizes which of the equipments 104, 105 is in operation. Thus, any of the equipments 104, 105 is selected by a notice from the management section 201.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a maintenance operation management device centralized management system.

[Conventional technology]

Conventionally, a central management device is connected to a duplex maintenance and operation management device via a switch circuit, and the central management device performs switching control of the switch circuit in order to transmit signals from the central management device.

[Problem to be solved by the invention]

The conventional centralized control equipment mentioned above is connected via a switch circuit, so it can only communicate with one of the redundant maintenance operation management equipment, and cannot receive signals from other maintenance operation management equipment. It's impossible. Therefore, even when both maintenance operation management devices are in an operable state, the state of only one device can be managed.

[Means to solve the problem]

The maintenance operation management device central management method of the present invention is a maintenance operation management device in which a carrier signal is detected by the time division multiplexing device from a central management device connected to a maintenance operation management device with a duplex configuration via a time division multiplexing device. A signal requesting notification of the operational state is transmitted to the central control device, and in response to this signal, a response signal notifying the operational state sent from the maintenance operation management device is analyzed by the central control device and transmitted to the time division multiplexing device. This configuration controls the signals.

[Effect]

In the present invention, the central management device includes a communication control section that communicates with a time division multiplexing device connected to the duplexed maintenance operation management device, and a duplexed system that analyzes signals received by this communication control section. It consists of a status management unit that manages the status of the active and non-operational systems of the maintenance operation management device, and an execution management unit that controls the communication control unit and the status management unit and controls signal transmission. ing.

The communication control section receives the signal sent from the time division multiplexing device, edits it into a format that can be easily processed within the central management device, and notifies the execution management section and the state management section. When the communication control section receives a carrier signal on the communication line with each maintenance operation management device detected by the time division multiplexing device, it notifies the state management section of a change in the line state. When a line carrier signal is detected, the status management unit transmits a signal requesting the maintenance operation management device connected to the line to notify the operation status. In response to this signal, each maintenance operation management device sends a response signal notifying the operating status of its own device, and the status management unit that receives this response signal can confirm which maintenance operation management device is in operation. On the other hand, when sending a signal from the central management device to each maintenance operation management device, whether it is a normal request to the active system or a request to the non-active system in special cases, the state management unit recognizes the active system and non-active system. The status management unit notifies the execution management unit and communication control unit of the status of the active system and non-operational system so that it can be transmitted to the active system.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a configuration diagram of an embodiment of the present invention, in which maintenance management devices 104 and 105 with a duplex configuration connected to a data communication network 106 are connected to a central management device 102 via a time division multiplexing device 103. are doing. When the time division multiplexing device 103 detects a carrier signal on the connection line with the maintenance and operation management devices 104 and 105, it transmits this signal to the central management device 102. The central management device 102 issues a status notification request to the maintenance operation management device in which the carrier signal has been detected. Based on the response signal to the request, the central management device 102 manages the status of the active system and the non-active system.

Next, the functions of the central management device 102 will be explained in detail. FIG. 2 shows the internal configuration of the central management device 102 shown in FIG. The communication control unit 200 controls transmission and reception of signals between the central management device 102 and the time division multiplexing device 103. The status management unit 201 issues a status notification request to each maintenance operation management device according to the communication line status between the time division multiplexing device 103 and each maintenance operation management device notified by the communication control unit 200, and performs execution management. It has the function of notifying the status of the active system and non-active system when a signal transmission request is received through the system. The execution management unit 202 uses the communication control unit 200 to send input signals from the central management device terminal 101 to each maintenance operation management device.
and has a function of controlling the state management unit 201.

between the time division multiplexing device 103 and the maintenance operation management device 1
The signal format between 04 and 105 is shown. The communication control section 200 shown in FIG. 2 edits the received signal in the format shown in FIG. 3(B) into the format shown in FIG.

Conversely, request signals from the execution management section 202 and the state management section 201 are passed to the communication control section 200 in the format shown in FIG. It is transmitted to multiplexer 103. The sequence diagram in FIG. 4 shows the above signal flow. In FIG. 4, when the time division multiplexing device 103 detects the carrier signal of the maintenance operation management device 104, it sends the signal in the format shown in FIG. 3(B) to the communication control unit 200 of the central management device 102. Communication control unit 2
00 notifies the state management unit 201 of this in the signal format shown in FIG. 3(A). The status management unit 201 that has analyzed this signal issues a status notification request to the maintenance operation management device 104 through the communication control unit 200. Maintenance operation management device 1
04 transmits a response signal to notify that its own operating status is poor (in operation or in non-operation). Similar signals are transmitted and received to the maintenance operation management device 105 as well. Thereby, the state management unit 201 can recognize which of the maintenance and operation management devices 104 and 105 is in the operating state.

Furthermore, when there is a signal transmission request from the central control unit 102, if the active system is aware of this, the signal to be sent to the active system and the signal not to be sent to the non-active system can be sent for maintenance and operation by notification from the management unit 201. Any of the management devices 104 and 105 can be selected.

〔Effect of the invention〕

As explained above, according to the present invention, by connecting the redundant maintenance operation management device and the central management device via the time division multiplexing device, a signal requested to be transmitted can be transmitted regardless of whether it is in the active system or not. It can be sent at the same time even if it is an operational system.
