In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, fig. 1 is a schematic structural diagram of an OLT protection early warning device adopted in the prior art, and as shown in fig. 1, a mode (not shown in the base station) of sharing a power supply with a base station or providing a power supply independent of the OLT is adopted for the OLT in the prior art, and when the commercial power supply stops, the power supply is switched to a battery of the base station power supply to supply power or is switched to a battery of the OLT independent power supply to provide power supply protection. Meanwhile, the early warning mechanism of the device adopts the dynamic ring warning of the associated base station, the warning information is uploaded to the wireless main equipment in a dry contact mode, and the wireless main equipment sends the warning information to the wireless network manager, so that the warning is generated in the background of the wireless network manager.
It can be understood that the device provided by the prior art is very easily influenced by objective conditions due to a single mode on power supply guarantee and early warning, for example, when an OLT power supply fails or a battery is aged, the OLT power supply cannot be used as a backup power supply to supply power, so that service interruption is caused due to insufficient subsequent navigation capacity of the OLT in power failure.
To solve the above problem, fig. 2 is a structural diagram of an optical line terminal power supply guaranteeing system according to an embodiment of the present invention, and as shown in fig. 2, the optical line terminal power supply guaranteeing system includes:
an optical line terminal OLT201, an independent power supply module 202 and a base station switch power supply module 203;
the optical line terminal is provided with a first power input port 204 and a second power input port 205, the first power input port 204 is connected to the base station switch power module 203, and the second power input port 205 is connected to the independent power module 202.
As shown in fig. 2, the OLT protection system provided in the embodiment of the present invention adopts a dual backup manner, that is, two power input ports are provided on an OLT201, which are a first power input port 204 and a second power input port 205, where the first power input port 204 is connected to a base station switch power module 203, and the second power input port 205 is connected to an independent power module 202. It is understood that the base station switch power module 203 and the independent power module 202 each include a battery that can supply current to the OLT201 as a backup power source when the OLT201 is not powered by the base station. Moreover, since the different power input ports are connected in parallel, the first power input port 204 and the second power input port 205 will not interfere with each other when carrying out current transmission.
It can be understood that, by adopting the manner provided by the embodiment of the present invention, a dual backup manner of the independent power supply module 202 and the base station switch power supply module 203 can be provided to provide power supply guarantee for the OLT201, and even if one of the power supply modules fails, the other power supply module can also complete the work of backing up the power supply. For example: when the base station is in a power failure condition, the base station mains supply of the OLT201 is stopped, then current can be input from the first power input port 204 and/or the second power input port 205, and at this time, the base station switch power supply module 203 and the independent power supply module 202 are simultaneously used as backup power supplies of the OLT201, so that the endurance time of the OLT201 is increased, and meanwhile, the emergency repair time is also prolonged.

It will be appreciated that the base station switching power supply module is typically a stand-alone larger cabinet installation and includes a greater number of equipment modules, and thus preferably takes the form of a modular power supply 401. The combined power supply 401 is stable in power supply and can adapt to various occasions. The lead-acid battery 402 has the excellent characteristics of long service life, large capacity, stable quality, high reliability and the like, and can provide enough electric energy for a larger charging system.

On the basis of the foregoing embodiment, fig. 6 is a schematic structural diagram of an optical line terminal early warning apparatus according to an embodiment of the present invention, and as shown in fig. 6, the optical line terminal early warning apparatus includes an optical line terminal power supply guarantee system 601, a first alarm module 602, and a second alarm module 603;
the first alarm module 602 is connected to a base station switch power supply module in the optical line terminal power supply support system 601, and the second alarm module 603 is connected to an optical line terminal in the optical line terminal power supply support system 601.
As can be seen from the content of the above embodiment, the optical line terminal power supply guarantee system provided by the embodiment of the present invention adopts a dual backup mode to guarantee the power supply of the OLT, so that the system has excellent power supply guarantee capability in various fault scenarios, and can greatly reduce the fault efficiency. On the basis, the early warning device of the optical line terminal provided by the embodiment of the invention can automatically monitor the fault information, and when the fault occurs, the early warning device can generate the warning information in time and send the warning information to the service background, so that a user can carry out emergency repair according to the content of the warning information in time.
Specifically, the optical line terminal early warning apparatus provided in the embodiment of the present invention includes an optical line terminal power supply guarantee system 601, a first warning module 602, and a second warning module 603. It can be understood that the alarm reporting mode adopted in the embodiment of the present invention is also a dual backup mode, and the first alarm module 602 and the second alarm module 603 are simultaneously configured to perform alarm monitoring on the optical line terminal power supply guarantee system 601. The base station switch power supply module reports alarm information through the first alarm module 602, the OLT independent power supply reports alarm information through the second alarm module 603, and the second alarm module 603 is directly connected with the OLT, so that the power-on condition of the power board of the OLT device can be directly monitored, and when one of the power terminals is used, the alarm information can be directly uploaded to the second alarm module 603, for example: when the power board in the monitoring OLT device finds that the independent power module is powered off, the alarm information indicating that the independent power module fails is sent to the second alarm module 603 in time.
The double-backup alarm mode provided by the embodiment of the invention can improve the active alarm monitoring rate and reduce the failure rate. Even if a certain section of monitoring line has a fault or the moving ring equipment has a fault, the fault information can still be normally uploaded to the background.
On the basis of the foregoing embodiment, fig. 7 is a schematic structural diagram of a first alarm module provided in the embodiment of the present invention, and as shown in fig. 7, the first alarm module includes a wireless master device 701 and a wireless network manager 702.
Preferably, the first alarm module provided in the embodiment of the present invention employs a wireless master device 701 and a wireless network manager 702. It can be understood that the first alarm module is connected to the base station switch power module, specifically, the base station switch power module is connected to the wireless master device 701 through an alarm line, and when alarm information is generated, the alarm information is uploaded to the wireless network manager 702 through the wireless master device, so that the wireless side monitoring alarm is realized, and the alarm uploading mode is stable and reliable.
On the basis of the foregoing embodiment, fig. 8 is a schematic diagram illustrating a connection between a second alarm module and an optical line terminal power supply guarantee system according to an embodiment of the present invention, and as shown in fig. 8, the second alarm module is a transmission GPON network management 801. The transmission GPON network manager 801 is directly connected with the OLT, the independent power module is connected with the OLT through the warning line 802 besides being connected to the power board of the OLT through the second power input port, and when the independent power module generates corresponding warning information, the independent power module firstly sends the warning information to the OLT through the warning line 802 and then sends the warning information to the transmission GPON network manager 801 through the OLT.
The bandwidth of a network management pipe for transmitting the GPON (Gigabit-Capable PON) is higher, so that the uploading speed of the alarm information is very high, and the situation that the alarm cannot be uploaded due to insufficient cruising ability of the independent power supply module can be avoided by adopting the network management pipe for transmitting the GPON.
On the basis of the foregoing embodiment, fig. 9 is a schematic flowchart of a method for guaranteeing a power supply of an optical line terminal according to an embodiment of the present invention, and as shown in fig. 9, the method includes:
901. acquiring fault detection information of an optical line terminal power supply guarantee system;
902. and if the fault of the base station switch power supply module is obtained according to the fault detection information, receiving the standby current transmitted by the independent power supply module.
It should be noted that, the execution main body of the embodiment of the present invention is the OLT, and the OLT is powered by the main and standby power supplies when operating normally. The implementation scenario of the embodiment of the invention is how to continue to ensure normal supply of the power supply of the OLT through the standby power supply when the main power supply fails or the main power supply conveying current cannot be normally acquired due to other reasons.
Specifically, in step 901, when power supply provisioning is required, the OLT may automatically obtain fault detection information of the entire optical line terminal power supply provisioning system, where the fault detection information is detected by a detection device disposed outside or inside the optical line terminal power supply provisioning system, and a main detection object is whether current is input to the first power input port and the second power input port, and if no current is input, it is determined that a fault occurs in a power module correspondingly connected to the first power input port, for example: if the first power supply input port is detected to have no current input within a period of time, the base station switch power supply module connected with the first power supply input port is judged to have a fault.
Further, in step 902, if it is known that the base station switch power supply module has a fault according to the fault detection information, at this time, the OLT may only use the independent power supply module as a unique backup power supply, and a current delivered by the independent power supply module at this time is a backup current in the embodiment of the present invention. When the main power supply cannot supply current, receiving standby current can also ensure that the OLT cannot quit service and leave management.
On the basis of the foregoing embodiment, fig. 10 is a schematic flowchart of a method for guaranteeing power supply of an optical line terminal according to another embodiment of the present invention, and as shown in fig. 10, the method includes:
1001. acquiring fault detection information of an optical line terminal power supply guarantee system;
1002. and if the fault of the independent power supply module is obtained according to the fault detection information, receiving the standby current transmitted by the base station switch power supply module. Similarly, the execution main body of the embodiment of the invention is the OLT, and the OLT can be powered by the main power supply and the standby power supply at the same time when working normally. The implementation scenario of the embodiment of the invention is how to continue to ensure normal supply of the power supply of the OLT through the standby power supply when the main power supply fails or the main power supply conveying current cannot be normally acquired due to other reasons.
Specifically, in step 1001, when power supply provisioning is required, the OLT may automatically obtain fault detection information of the entire optical line terminal power supply provisioning system, where the fault detection information is detected by a detection device disposed outside or inside the optical line terminal power supply provisioning system, and a main detection object is whether current is input to the first power input port and the second power input port, and if no current is input, it is determined that a fault occurs in a power module correspondingly connected to the first power input port, for example: and if the second power supply input port is detected to have no current input within a period of time, judging that the independent power supply module connected with the second power supply input port has a fault.
Further, in step 1002, if it is known that the independent power supply module has a fault according to the fault detection information, at this time, the OLT may only use the base station switch power supply module as a sole backup power supply, and the current transmitted by the base station switch power supply module is the backup current in the embodiment of the present invention. When the main power supply cannot supply current, receiving standby current can also ensure that the OLT cannot quit service and leave management.
It can be understood that if the detection result is that independent power supply module and base station switch power supply module do not break down, if the base station stops supplying power this moment, then can carry out current input through first power input port and second power input port simultaneously, base station switch power supply module and independent power supply module are as back-up source simultaneously this moment to the back-up current mutual noninterference of the two input, and then can increase duration of OLT, the time is salvageed in the extension.
On the basis of the foregoing embodiment, fig. 11 is a schematic flow chart of an optical line terminal early warning method provided in an embodiment of the present invention, and as shown in fig. 11, the method includes:
1101. acquiring alarm information;
1102. and if the acquired alarm information comes from the base station switching power supply module, sending the alarm information to the first alarm module.
As can be seen from the content of the foregoing embodiments, the embodiment of the present invention provides an early warning device for an optical line terminal to perform monitoring and early warning, and when a fault is monitored, corresponding warning information is generated and sent to a corresponding warning module, so that a backend person can process the fault in time according to the warning information.
Specifically, in step 1101, the OLT may automatically detect a fault, and when a fault occurs, alarm information corresponding to a fault cause is generated, and generally, the dry contact alarm information of the power module includes four paths of information, which are a main power alarm, a low voltage alarm, a rectification alarm, and a fuse alarm. According to the position and the generation characteristics of the alarm information, the source of the alarm information can be judged. For example: when no commercial power is input into the base station switch power supply module, generating a main power alarm of the base station switch power supply module; when the battery of the base station switch power supply module supplies power to low voltage, generating a low voltage alarm of the base station switch power supply module; when a rectification module of the base station switch power supply module has a fault, generating a rectification alarm of the base station switch power supply module; and when the fuse wire appears in the base station switch power supply module, generating a fuse wire alarm of the base station switch power supply module.
Further, in step 1102, when any one of the four paths of alarm information is generated, if it is determined that the alarm information is from the base station switching power supply module, the alarm information is sent to the first alarm module, and specifically, the base station switching power supply module uploads the alarm information to the wireless network manager through the wireless master device.
On the basis of the foregoing embodiment, fig. 12 is a schematic flowchart of a further optical line terminal early warning method provided in an embodiment of the present invention, and as shown in fig. 12, the method includes:
1201. acquiring alarm information;
1202. and if the acquired alarm information comes from the independent power supply module and/or the optical line terminal, sending the alarm information to the second alarm module.
As can be seen from the content of the foregoing embodiments, the embodiment of the present invention provides an early warning device for an optical line terminal to perform monitoring and early warning, and when a fault is monitored, corresponding warning information is generated and sent to a corresponding warning module, so that a backend person can process the fault in time according to the warning information.
Specifically, in step 1201, the OLT may automatically detect a fault, and when a fault occurs, alarm information corresponding to a fault cause is generated, and generally, the dry contact alarm information of the power supply module includes four paths of information, which are a main power alarm, a low voltage alarm, a rectification alarm, and a fuse alarm. According to the position and the generation characteristics of the alarm information, the source of the alarm information can be judged. For example: when the independent power supply module has no commercial power input, generating a main power alarm of the independent power supply module; when the battery of the independent power supply module supplies power to low voltage, generating low voltage alarm of the independent power supply module; when the rectifying module of the independent power supply module fails, generating a rectifying alarm of the independent power supply module; and when the fuse occurs in the independent power supply module, generating a fuse alarm of the independent power supply module.
Further, in step 1202, when any one of the four paths of alarm information is generated, if it is determined that the alarm information is from the independent power module, the alarm information is sent to the second alarm module, specifically, the independent power module sends the alarm information to the OLT through the alarm line, and then the alarm information is uploaded to the GPON network manager through the OLT.
Meanwhile, in step 1202, the embodiment of the present invention further detects the power board of the OLT device, and if the power board of the OLT device fails, an alarm message is also generated, that is, the alarm message is originated from the OLT, and a specific detection method is to detect a power-on condition of the power board to determine whether the power module is powered normally. If the alarm information comes from the OLT, the alarm information is directly sent to the second alarm module, and specifically, the OLT directly uploads the alarm information to the GPON network management system.
The alarm mode provided by the embodiment of the invention has the advantages that the alarm information uploading speed is high and stable, the alarm process adopts a double backup mode, any set of power supply is interrupted, and the power supply can be directly uploaded to the transmission GPON network management by the OLT, so that the alarm active monitoring rate is improved, and the failure rate is reduced.
