Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a flowchart of a passive optical network alarm management method according to an embodiment of the present invention, and as shown in fig. 1, the flowchart includes the following steps:
s100, the optical line terminal OLT receives a power failure alarm sent by the optical network terminal ONU.
S102, calculating the number of the ONUs with the power failure alarm under the PON port of the passive optical network to which the ONUs belong, comparing the number of the ONUs with the number of the ONUs under the corresponding PON port, and outputting a first comparison result.
And S104, if the first comparison result accords with a first preset threshold range, judging that the position of the PON is powered off.
S106, calculating the number of the PON ports which are in line with the same geographic area and are judged to be powered off, comparing the number of the PON ports which are judged to be powered off with the total number of the PON ports in line with the same geographic area, and outputting a second comparison result.
And S108, if the second comparison result accords with the second preset threshold range, judging that the area has power failure.
Specifically, a power failure alarm sent by an optical network unit ONU refers to that when a power failure occurs, a CPU of the ONU can still operate for a time period T1, so as to report a power failure alarm message to an OLT, the time of T1 is generally about 4ms, the principle mainly refers to a relationship between the power failure alarm time T1, a capacitor C and a board power consumption P, during the power failure, during the time period T1, the ONU operates normally, although the input voltage of a port decreases continuously, during a period of switching a power supply and the like, a voltage required by a chip remains constant, and during the time period, the power of the ONU remains constant, that is, a model of the ONU during the time period T1 is a device in which the voltage decreases continuously but the power consumption does not change.
In one example, a cell or a large community comprises 10 buildings, each floor has 64 households, each OLT is provided with 2 PON ports, each PON port is connected into one building, and the splitting ratio meets the splitting requirement. When one of the ONU equipment is powered off, the power-off reason can be that no person is in a long-time business home and the power is off due to insufficient payment or the power is overhauled and powered off, and the OLT normally receives the power-off alarm sent by the ONU at the moment.
And when 64 ONUs of the building have power failure or 62 ONUs (each having a standby power supply or an external power supply) or all power failure, reporting all the ONU power failure alarms to the OLT in a short time, according to the step S102, calculating the number of ONUs reporting the power failure alarms under the same PON port, comparing the number of ONUs with the total number under the PON port, and outputting a first comparison result, and if the first comparison result is within a preset threshold range, determining that the building has power failure.
Such a determination can basically indicate that the power failure of the whole building exists, and certainly, an extremely individual situation exists, for example, only 10 residents in the whole building normally use the power, and other residents are in a normal use state, and once 5 of the 10 residents are in the power failure, when the output first comparison result meets a first preset threshold range, the power failure of the whole building is easily misjudged, so in an actual working condition, comprehensive judgment needs to be performed by combining feedback of a user site, and an operator needs to perform pre-statistics on the situations, so that the accuracy of judging whether the power failure exists can be further improved.
In addition, as described in steps S104 and S106, the number of PON ports where power failure occurs may be calculated and tabulated with the total number of PON ports in the cell, and a second comparison result is output, and if the second comparison result is within a preset threshold range, it is determined that the entire cell is powered off. Certainly, all the OLT devices corresponding to all PON ports, and corresponding building numbers and cell names may be marked and associated in advance, and the marking and the associating manner are the same as the manner for defining and monitoring different areas in the related monitoring system, and are known, and are not described herein again.
Through the steps, the comprehensive judgment of the power failure alarm can provide decision basis for the network center so as to enable the network center to make a reasonable decision, and whether operation and maintenance personnel are discharged for field maintenance is determined, so that the user experience is improved.
Further, the first comparison result includes a ratio of the number of ONUs with power failure alarm to the total number of ONUs under the corresponding PON port;
the second comparison result includes a ratio of the number of PON ports that have been determined to have been powered off to the total number of PON ports.
The first preset threshold range may be set autonomously, for example, the first preset threshold range is 90% to 100%, if the total number of ONUs at the same PON port is 64, and if 60 ONUs at the PON port have power failure alarms, the ratio of the total number of ONUs is 60/64=94%, and the ratio belongs to the first preset threshold range, it is determined that the building where the PON is located has power failure, and the network center may not need to dispatch operation and maintenance personnel.
Similarly, the second preset threshold range may be set autonomously, for example, the second preset threshold range is 70-100%, if the total number of PONs belonging to the same cell is 10, if 8 PON ports in the cell are powered off, the ratio thereof is 8/10=80%, and if the ratio falls within the second preset threshold range, it is determined that the cell is powered off, and the network center may not need to dispatch operation and maintenance personnel.
Fig. 2 is a further flowchart of a passive optical network alarm management method according to an embodiment of the present invention. As shown in fig. 2, based on steps S100-S108, the method further comprises:
s200, the network management server stores the power failure plan uploaded in the controlled area in advance.
S202, analyzing the power failure plan to obtain geographic position information and time information.
S204, the network management server receives power-off information sent by the position where the PON is located, wherein the power-off information comprises power-off position information and power-off time information;
s206, comparing the geographical position information and the time information obtained by analyzing the power failure plan with the received power failure position information and the power failure time information sent by the position of the PON correspondingly.
S208, if the comparison result is consistent, judging that the power is cut off according to the plan, and dispatching operation and maintenance personnel is not needed; if the comparison result is not consistent, the equipment is judged to be in fault power failure, and operation and maintenance personnel need to be dispatched.
Specifically, under actual working conditions, the accuracy of the fault judgment is related to the operation and maintenance efficiency and the use experience of the customer, so that a certain misjudgment condition still exists only by the reported power failure alarm, and even if the network center judges that the power is off, operation and maintenance personnel are not dispatched, the reason of the network disconnection still needs to be explained for the user.
In step S200, the network management server can establish a connection with the property and/or the power department in the controlled area, can store the power failure plan in the controlled area in advance, and can analyze the geographic position information and the time information in the power failure plan; after receiving the power failure information of the PON, the network management server can compare the position information and the power failure time information of the PON with the geographical position information and the time information summarized by the power failure plan obtained through analysis.
Illustratively, the network management server receives the power failure alarm: the method comprises the steps of ' X month X day X minute X second in 201X year, X minute of light district, No. 109 building power failure ' in a network management server, then searching a power failure plan of corresponding time in a network management server, finding that the power failure plan ' 201X year X month X day X minute-201X year X day X minute, south mountain streets are stored, electric power debugging/maintenance is carried out on the light district, No. 109 building and the like in a coverage street range, and if the time ' 201X year X month X day X minute X second ' in power failure warning is consistent with the time ' 201X year X month X day X minute-201X year X day X minute ' in power failure plan or is in the time range of the power failure plan, and the geographic positions ' light district, No. 109 building ' are consistent, determining and recording the power failure as the plan, reporting to a network center, wherein operation and maintenance personnel do not need to be dispatched by the network center, and the user can be guaranteed to reply.
If the comparison result of the time and the geographic position is inconsistent, the equipment fault is determined and recorded, and the equipment fault is reported to the network center, and the network center needs to send operation and maintenance personnel to the location of the fault for operation and maintenance guarantee. The failure of the device typically occurs due to the disconnection of the ONU caused by a break in the optical cable, a failure during the power module of the device, etc.
By means of automatic network judgment and combination of power failure messages issued by the power department or/and the property department, the power failure messages can be judged more accurately, and accordingly accurate guidance of dispatching work of operation and maintenance personnel is facilitated.
Furthermore, the network management server receives the power-off information sent by the area; if the area sending the power failure information is judged to be power failure or planned power failure, operation and maintenance personnel do not need to be dispatched.
Specifically, the network management server receives power-off information sent out in a controlled area, namely, a plurality of PON ports in the area all send power-off alarms, and the plurality of PON ports in the area refer to a plurality of PON ports between the same OLT in the area and PON ports between different OLTs; once it is determined that the area, for example, the entire cell is powered off, there is almost no network outage due to equipment failure, and therefore, the network center does not need to send operation and maintenance personnel to reach the powered off area.
