Difficulties in maintaining such private networks are:
1. the fault can not be positioned quickly and accurately: the maintenance process of the project is generally that a platform video monitoring party monitors that a certain point has no picture or has poor page quality, then reports to a network operator to perform network fault troubleshooting, the network operator dispatches maintenance personnel to reach a specified monitoring point to check the power receiving and data signal receiving conditions of the access point network access terminal, if the situation is that the situation is not a network problem, the maintenance personnel feeds back the situation to a camera integration party to perform camera fault processing, and if the situation is that the situation is a network problem but is not the problem in the current section, other professionals are scheduled to perform barrier processing. Although the above processing flow is completed, the efficiency is extremely low and the labor cost is high.
2. Network failure cannot be actively discovered: at present, fault initiation is mainly declared, a tool for actively patrolling network equipment is lacked, fault troubleshooting cannot be actively carried out, fault processing is passive, processing can be carried out after a user reports faults, the online rate is not rapidly promoted and maintained, and the satisfaction degree of the user to a network operator is not promoted.
3. The obstacle reporting process information sharing mechanism is insufficient: the video monitoring party knows the video picture condition of the point location, the network operator knows the related information of the network, and the languages of the two parties are different, so that the timeliness of obstacle processing is influenced.
4. The monitoring points of the project are mainly located in outdoor scenes such as roads and cells, the monitoring of the current outdoor installation is very much, and the accurate finding of the specific monitoring points during fault processing is also one of the difficulties in maintenance.

step a2, according to the ID of the access service of the access point and the IP address of the access point camera, the obstacle positioning module (106) calls a PING interface of the OLT through the network management platform (105), the IP address of the PING camera, if the PING is on, no fault is fed back, and if the PING is not on, the step a3 is entered;
step a3, according to the ID of the access point access service, the obstacle location module (106) obtains the service full-range state information through the network management platform (105), including: the method comprises the following steps that ONU power failure, ONU equipment failure, branch link failure, main optical cable failure and OLT PON port failure are carried out, if no failure is displayed in the fed back whole-process state information, the final result is fed back to be camera failure, and if the fed back whole-process state information has failure, the final result is fed back to be corresponding failure information;
for an EPON private network, the system realizes the positioning of a specific fault section by executing the following steps:
step b1, acquiring two attributes of an IP address and a broadband account of one camera;
b2, calling a PING interface through the IP address of the camera, judging whether the camera can PING, if so, indicating that a camera link is normal, and directly feeding back that the camera is normal; for the condition that PING is not communicated, a network fault interface in the routing inspection module is requested, fault information is obtained through the network fault interface, judgment is sequentially carried out from top to bottom according to two modes of an OLT-ODN-ONU or an OLT-ODN1-ODN2-ONU of a networking structure of an EPON, if OLT2ODN =0& & oltdevestate =0, an OLT equipment fault is prompted, and an OLT icon is changed into red;
if OLT2ODN =0& oltdevestate =1& (oltponadminstate = 0| | oltpopertrostate = 0), alerting the OLT device to fail and changing the OLT icon to red;
if the OLT2ODN =0& oltdevestate =1& (oltponadminstate =1& & oltpoperiostat = 1), a trunk link failure is declared and the OLT icon is changed to red, the connecting line between the OLT and the ODN indicates red;
for the case of OLT2ODN =1, indicating that the trunk link is normal, confirmation of primary splitting or secondary splitting is performed:
when the ODN2ODN =0, it indicates that only the first-order light splitting is performed, and the system continues to perform the fault determination at the ONU downward;
if the ODN2ODN =1, indicating that secondary light splitting is performed, searching all ONU of the ODN downstream through the ODN2 by the system, and judging the ONU fault, if all the ONU downstream cameras IP are ping-out and the ONU states are normal, indicating that faults between primary and secondary light splitters are performed;
if the distance between the optical splitter and the optical splitter is not a null value, secondary light splitting is confirmed, in the secondary light splitting, ODN2ODN =0 shows that a secondary light splitting link fails, the failure of the secondary light splitting link is prompted, and a connecting line between the optical splitter and the optical splitter is displayed in red;
ODN2ODN =1 indicates no fault between the secondary beamsplitters;
ODN2ONU =0 shows that the branch link between ODN and ONU is in fault, the system prompts the fault of the branch link, the fault of the branch link is divided into three conditions of fault of the optical splitter, broken branch optical fiber and problem of the fused fiber at the tail end of the ONU, and the specific reason needs to be checked on site;
when ODN2ONU =1, indicating that the whole link has no fault, executing step b3, and judging the fault on the ONU;
b3, if the ONU equipment is not powered, indicating that the ONU is powered off, and prompting the ONU fault or the ONU power off by the system;
if ONUdevicestate =0, indicating that the ONU equipment is abnormal in operation, and prompting the ONU by the system to have a fault or the ONU equipment is abnormal in operation;
if ONUdevicestate =1, it is determined that the camera has a failure.
