Background technique

At present, optical transmission equipment is mainly remotely managed through a fiber-optic DCC (Data Communication Channel) connection. However, in the relevant standard recommendations, there is no special equipment power-off alarm. Therefore, if the transmission equipment is interrupted, the central network management only It can report alarms related to service interruption and alarms such as DCC connection failure. It is impossible to distinguish whether the transmission equipment is caused by a power failure or other line. In this case, if the service interruption caused by the power failure of the device occurs, the user will think that it is the cause of the device itself, and directly complain to the customer service center; if there is a short interruption, it is more difficult to determine that the root cause is short break. If the short-term operation of the device or the device is not normal, it may cause unnecessary maintenance costs. Therefore, a method is needed to directly report the abnormal power-off of the transmission device to the network management system and present it to the user. Summary of the invention

The method for implementing the power failure alarm of the transmission device provided by the present invention specifically includes the following steps: Step 1: When the external power supply of the transmission device is powered off, the internal power supply module provides a power supply maintenance function, and generates a power failure alarm signal to notify the device. Control module.

Among them, the internal power module has power-off detection and continuous power supply.

The power supply function of the internal power module can be maintained for a short period of time, or it can be maintained for a long time. The maintenance time of the power supply can ensure that the alarm packets are sent to the network management system.

The power module of the transmission device can notify the control module of the transmission device of the power failure alarm signal in the highest priority task mode, or can be used in other manners, such as generating alarms, interrupts, and the like.

Step 2: After the power supply module of the transmission device maintains the power supply, the control module of the transmission device receives the power failure alarm signal, and forwards the pre-defined power failure alarm message to the access network through the DCC connection of the optical interface module. The transmission device of the element transmits a power-off alarm message to the network element management module and the optical interface module of the transmission device. When the transmission device sends a power failure alarm message, it can be repeated multiple times until the transmission device loses power.

Step 3: After receiving the power-off alarm message, the transmission device that is the access network element is processed by the control module and reported to the network management system by the network element management module.

Because the interrupted electrical alarm message is sent to the network element management unit of the transmission device itself, if the power transmission device that is powered off is the access network element, it is directly reported by the network element management module of the transmission device itself. The electrical alarm packet is sent to the network management system.

Step 4: After receiving the power-off alarm packet, the network management system parses the packet and reports the power-off alarm information to the user.

Step 5: When the transmission device resumes external power supply, an alarm recovery signal and an alarm recovery message are generated to the network management system, which specifically includes the following steps:

1 10, When the transmission device resumes external power supply, the internal power module generates an alarm recovery signal to inform the control module of the device.

After receiving the power failure alarm recovery signal, the control module of the transmission device forwards the pre-defined alarm recovery text to the transmission device that is the access network element through the DCC connection of the optical interface module, and manages the network element of the device at the same time. The module and the optical interface module send alarm recovery packets.

After receiving the alarm recovery packet, the transmission device that is the access network element is processed by the control module and reported to the network management system by the network element management module.

The main function of the control module is to receive alarm recovery packets and forward them to both the optical interface module and the NE management module.

Because the alarm recovery message in step 120 is sent to the network element management unit of the transmission device itself, if the transmission device that recovers from power failure is the access network element, it reports directly through the network element management module of the transmission device itself. The police resume the message to the network management system.

After receiving the alarm recovery packet, the network management system parses the packet and cancels the power failure alarm report.

Notify the control module E of itself;

Step 2: When the control module E receives the power failure alarm signal J, writes the power failure alarm message K to the optical interface module F and the network element management module G through the communication bus, and the optical interface module F disconnects the power supply. The electrical alarm packet K is transmitted to the adjacent transmission device B whose power source is working normally through the DCC channel H, where B is the access network element of the network management system;

Step 3: After receiving the power-off alarm message K of the transmission device A, the optical interface module F of the transmission device B forwards the packet to the network management system C through the network element management module G through the control module E. Step 4: After receiving the power failure alarm message of the transmission device A, the system C reports the power failure alarm on the network management system.

After receiving the power failure alarm message, the network management system C reports the power failure alarm. When the alarm recovery message is not received, the power failure alarm is not reported.

As shown in FIG. 2, the flow of the method for implementing the alarm recovery of the transmission device in the embodiment of the present invention is as follows: Step 1: The transmission device A restores the external power supply, and after the device works normally, the power failure alarm recovery signal J is generated to notify the control module E of itself;
