step S12: acquiring abnormal overhaul record information of a first distribution bit, and extracting target characteristics about a target and action time periods corresponding to the target characteristics in the abnormal overhaul record information;
corresponding monitoring equipment is arranged in the plurality of distribution bits and used for collecting local overhaul record information of the distribution bits; in the normal overhaul process of some non-first distribution positions, due to intentional or unintentional reasons of related personnel, the first distribution positions are abnormal, such as the process of connecting the non-first distribution wires into the electric energy meter, the first distribution positions are carelessly damaged, the first distribution positions are abnormal in the branch meter wiring, and the system detects the electricity metering abnormality, so that the power failure is caused; at this time, by recording target characteristics of related personnel, such as face information, wearing information with a work card and the like, and a time stamp of maintenance operation, the method mainly comprises an action period corresponding to abnormality of a first distribution bit, such as detecting related operation of the related personnel on the first distribution bit in a first time period (actually, the intention of the operation may not be based on the first distribution bit but on non-first distribution bit), and then detecting abnormality of the first distribution bit, thereby taking the first time period as the action period;
Step S13: generating a first monitoring query instruction according to an action time period, and issuing the first monitoring query instruction to a second distribution bit to acquire a third distribution bit which is returned by the second distribution bit and accords with the action time period, wherein the second distribution bit comprises a distribution bit which is in a set distance range with the first distribution bit in an associated distribution sub-area; firstly, positioning distribution bits in a set distance range between the distribution bits and the first distribution bits through a first monitoring query instruction, wherein the distribution bits are in maximum suspicion in the associated distribution subareas due to the close range of the positions, so that first, a third distribution bit related to the existence of the first distribution bit can be determined in time, and the action time periods are coincident, wherein the coincidence of the action time periods corresponding to the first distribution bit and the third distribution bit is included; monitoring equipment in the second distribution bit can monitor based on the local overhaul record information of the monitoring equipment, and screening a third distribution bit conforming to the action time period, and if the third distribution bit conforms to the action time period, feeding back the identification of the third distribution bit, such as the equipment identification of the monitoring equipment in the third distribution bit;
step S14: when the third distribution bit is at least one, generating a second monitoring query instruction according to the target feature, and issuing the second monitoring query instruction to the third distribution bit to acquire suspicious maintenance record information which is returned by the third distribution bit and accords with the target feature; the third distribution bit is determined, and only the second monitoring query instruction is directly sent to the third distribution bit based on the third distribution bit, after the monitoring equipment of the third distribution bit receives the target feature, the third distribution bit is identified again to judge whether the local overhaul record information of the third distribution bit accords with the target feature, namely whether the local overhaul record information contains the same target feature, if so, the monitoring equipment of the corresponding third distribution bit feeds back suspicious overhaul record information which accords with the target feature; suspicious service log information is generally more comprehensive and complete than abnormal service log information because its primary purpose is to service non-first distributed bits;
Step S15: and associating the suspicious maintenance record information with the power abnormal event. According to the returned suspicious maintenance record information, the suspicious maintenance record information can be correlated with the power abnormal event so as to facilitate maintenance correlation operation and responsibility.
When the method is applied, the abnormal distribution positions corresponding to a certain subarea in the associated distribution subarea of the centralized use area are identified based on the power abnormal event of the certain subarea, so that the first distribution bit is positioned, the abnormal maintenance record information of the first distribution bit is further obtained, and the target characteristics about the target and the action time periods corresponding to the target characteristics in the abnormal maintenance record information are extracted; and generating a first monitoring query instruction and a second monitoring query instruction according to the action time period and the target characteristics respectively, finally acquiring suspicious maintenance record information which is returned by the third distribution bit and accords with the target characteristics, and generating the first query instruction and the second query instruction, so that the monitoring analysis efficiency of the third distribution bit is improved, the time of association analysis can be effectively shortened, the data transmission quantity of the maintenance record information can be reduced, the determined suspicious maintenance record information can be further determined, and maintenance reference and responsibility tracking reference can be provided for operation association damage in the electric power maintenance process.
As shown in fig. 2, as a preferred embodiment of the present invention, the identifying the abnormal distribution position according to the distribution line of the concentrated use area includes:
step S101: positioning an electric power distribution circuit of a centralized use area; the power distribution circuit integrates power distribution circuits of a plurality of subareas and connecting circuits of the centralized use areas;
step S102: specifically, as shown in fig. 3, based on step S102, identifying the abnormal distribution position specifically includes:
step S1021: positioning interval detection nodes at two ends of the power distribution line, wherein the interval detection nodes at two ends of the power distribution line are a first node and a second node respectively; the first node and the second node generally refer to a current departure point and a current sink point of the power distribution circuit, and can correspond to the positive and negative poles of a power supply of a loop where the power distribution circuit is located, and are generally located at a position far from a centralized use area, so that the power supply is generally good;
step S1022: acquiring a first communication detection signal between a node to be selected and an intermediate node, wherein the node to be selected is a first node or a second node, and the intermediate node is a node positioned at a central position between the node to be selected and a certain sub-region; the intermediate node is provided with an automatic detection function and is used for detecting a first communication detection signal, and the first communication detection signal is sent out from the first node or the second node;
Step S1023: judging whether the first communication detection signal is qualified or not; whether the first communication detection signal is qualified or not can be used for detecting whether transmission of the communication detection signal sent from the node to be selected is complete or not, namely whether the communication detection signal reaches the intermediate node or not through line transmission between the node to be selected and the intermediate node;
step S1024: if yes, positioning a first line between the intermediate node and a certain subarea, and judging that the abnormal distribution position is in the first line; for example, when the detected attenuation value of the communication detection signal is within the loss range of the set signal strength of the first line (related to factors such as line length), it should be determined that the first communication detection signal is qualified, that is, the second line between the node to be selected and the intermediate node is complete, and the first line between the intermediate node and a certain sub-area is abnormal; at this time, the high probability is that the abnormal distribution position is abnormal, because the abnormal distribution position is overhauled, the first distribution position of the centralized use area is most likely to be failed, and the method is applicable to the condition that the first distribution position is positioned on a first circuit;
step S1025: if not, a second line between the node to be selected and the intermediate node is positioned, the abnormal distribution position is judged to be in the second line, and the first line and the second line are contained in the centralized use area. The situation is similar to the situation in step S1024, in which the probability is that the abnormal distribution position is abnormal, because there is maintenance on the abnormal distribution position, it is highly likely that the first distribution position of the central usage area is faulty, and the situation that the first distribution position is in the second line is applicable;
In this embodiment, through the detection cooperation between the intermediate node and the node to be selected, the detection efficiency of the fault site can be improved, the point-by-point detection in the first line and the second line is not required, and the line including the abnormal distribution position can be rapidly located. Compared with the prior art, the method has the advantages that the first node or the second node is replaced by the node to be selected, the detection flow is replaceable, and the steps are simple.
In combination with the above embodiment, as a preferred embodiment of the present invention, the method further includes:
step S20: and positioning a corresponding line of the associated distribution sub-area, acquiring a shot image of the corresponding line, judging whether the non-area position of the corresponding line has abnormal connection according to the shot image, if not, judging that the abnormal distribution position is in the associated distribution sub-area of the centralized use area, wherein the corresponding line comprises a first line or a second line. The shot image is generally shot by shooting equipment of a corresponding line, and as the corresponding line is generally a first line or a second line and only comprises non-area positions (non-associated distribution sub-area positions) in the first line or the second line, whether the non-area positions have abnormal connection or not can be identified through image detection; when no connection abnormality exists, the connection of the non-area position is recovered, whether the first distribution position is abnormal or not is judged, and if so, the abnormal distribution position can be judged to be in the associated distribution subarea of the centralized use area;
Specifically, judging whether the non-area position of the corresponding line has abnormal connection or not, comparing the similarity between the image of the non-area position of the corresponding line and the line image of the abnormal connection, and judging that the non-area position has no abnormal connection when the image of the non-area position of the corresponding line and the line image of the abnormal connection do not meet a set similarity threshold; therefore, the detection method provided by the embodiment can locate whether the abnormal distribution position is in the associated distribution subarea of the centralized use area.
As shown in fig. 4, as a preferred embodiment of the present invention, the obtaining the abnormal maintenance record information of the first distribution bit includes:
step S121: sending an acquisition instruction to the central equipment of the associated distribution subarea so as to acquire feedback information returned by the central equipment;
for the associated distribution subareas, a central device is generally arranged, the central device is arranged at a position where the key is protected, the position of the central device is important, and the central device can provide the issuing of related instructions, the interaction of the instructions and the like for each distribution position;
step S122: when the feedback information comprises a local image and an equipment identifier of central monitoring equipment, judging that first monitoring equipment with a first distribution bit fails, acquiring a global image acquired by the central monitoring equipment according to the equipment identifier, wherein the global image covers the first distribution bit, and the abnormal maintenance record information comprises a global image and/or a local image;
The central equipment can acquire a local image, if the local image is detected, the first monitoring equipment starts an emergency program to send the emergency program to the central equipment, and the first monitoring equipment fails, if the first monitoring equipment directly tries to interact with the first monitoring equipment, if the first monitoring equipment does not respond, whether the first monitoring equipment has specific failure or not can not be known, and the interaction is limited; after the central equipment receives the local image, detecting a fault emergency starting mark in the local image, directly retrieving central monitoring equipment corresponding to the first monitoring equipment at the moment, and controlling the central monitoring equipment to acquire a global image covering the first distribution bit; the first distribution bit may be monitored from a global perspective;
from the above, because of the preset program, the interaction with the central device can be simplified, and the specific preset program will be described below;

In the preset program, for the first monitoring device, before the first monitoring device fails, the first monitoring device collects a local image of the first distribution bit and performs self-checking, and when the first monitoring device detects that the first monitoring device changes from a non-failure state to a failure state, the first local image collected at least at the end moment of a frame is sent to the central device. At least one frame of local image, generally a certain frame or a plurality of frames of images with faults caused by non-faults are detected; and at the end, generally reflecting the scene that the overhaul action of the detection personnel causes the state of the first distribution bit to change; the local image at the moment is provided with a fault emergency starting mark; the failed emergency start means that when the self-body changes from a non-failed state to a failed state, an emergency (standby) program is started, for example, a standby power supply, a standby network and the like are started, and the local image is sent to the central equipment;
when the method is applied, the situation that the abnormal overhaul record information is directly obtained through interaction with the first monitoring equipment is fully considered, and the first monitoring equipment possibly changes the state of the first distribution bit from a non-fault state to a fault state due to overhaul actions of detection personnel, so that the step of obtaining the abnormal overhaul record information of the first distribution bit, which is provided by the embodiment, ensures that local images are stored, even if the first monitoring equipment is faulty, at least one frame of local image reflecting the overhaul actions of the detection personnel can be obtained, and in addition, through interaction between the central equipment and the first monitoring equipment and the central monitoring equipment, the switching from the local image to the global image in an emergency state can be ensured, so that the integrity of the abnormal overhaul record information is ensured.

When the method is applied, the qualified overhaul record information is generated by combining the overhaul request and the local image, the qualified overhaul record information has strict distribution bit correspondence, and the correlation and the distribution among the distribution bits in the set distance in the correlation distribution subarea are considered, so that effective reference can be provided for monitoring analysis of the first distribution bit.
As a preferred embodiment of the present invention, the method further comprises:
step S50: and when the number of the third distribution bits is smaller than one, the second distribution bits are redetermined, and the redetermined second distribution bits comprise distribution bits which are in a non-set distance range between the first distribution bits and the associated distribution sub-area.
