for example, when the performance parameter exceeds the performance threshold and continues for a period of time (e.g., 4 hours may be set, specifically, preset by the system depending on the nature of the parameter), the base operating parameter is considered abnormal.
S230, if the deviation between the basic operation parameter and the reference value is not greater than a preset deviation value and the periodic variation of the basic operation parameter is not greater than a variation threshold, judging that the basic operation parameter is normal.
It should be noted that the periodic variation of the basic operation parameter may be understood as a fluctuation variation value of the basic operation parameter, and the calculation of the fluctuation variation value of the basic operation parameter is well known to those skilled in the art, and will not be described herein.
After the basic operation parameters are judged to be normal, whether the online record and the offline record are normal or not is judged.
S300, if the basic operation parameters are normal, analyzing whether the online record and the offline record are normal;
it should be understood that the determination may be specifically performed according to the frequency of the on-line and off-line in the on-line and off-line records, for example, by determining whether the ONU has multiple on-line and off-line records in a preset time, that is, if the on-line and off-line records in the preset time exceed a preset normal value, the on-line and off-line records are considered to be abnormal.
Specifically, the upper and lower line records are shown in table 3 below.

Further specifically, as shown in fig. 6, determining the fault point location according to the ONU offline reason includes:
s421, judging whether the ONU offline reasons are batched ONU abnormal offline;
s422, if the ONU is offline abnormally, determining the fault point location as the PON terminal equipment fault;

and if the difference value calculation result is larger than a preset threshold value, determining that the ODN has faults.
In the embodiment of the invention, the ODN line information of the ONU is acquired through ODN resource management and management, and whether the performance degradation of the ODN occurs is judged through analyzing the optical link loss. As shown in fig. 8, a complete link diagram of the ODN is shown.
The optical link loss of the onu=pon port transmission optical power-ONU reception optical power.
The optical link loss of an ONU generally does not change much, and for example, an average value of 1 month in the initial system may be used as a reference value of the optical link loss. The ONU optical link loss reference value is an ODN line preset value.
1 month average = average of current optical link loss of ONU calculated, if 1 month average deviates from the reference value by about 20%, this indicates that ODN quality changes, and an active operation and maintenance work order is sent out.
It should be understood that if the basic operation parameters are normal and the on-line and off-line records are normal, no fault is considered, and no operation and maintenance work order is required to be generated.
S500, generating an operation and maintenance work order according to the fault point position of the ONU, and sending the operation and maintenance work order to a work order system.
