When the intelligent terminal equipment breaks down, a customer usually reports the repair to an equipment manufacturer in a repair reporting mode of dialing a customer service hotline telephone, the description of the problem by the customer is mostly strong in subjectivity, and context information of fault information is lacked, so that the fault positioning is not accurate enough, and the problems of high equipment operation and maintenance cost, low maintenance efficiency, low customer satisfaction degree and the like are caused. For a traditional IT operation and maintenance system or monitoring, the early warning is carried out on the state of equipment in real time at present, an automatic fault recognition mechanism is simple in strategy, filtering is not carried out on module instantaneous faults, communication transient faults or faults which can be automatically recovered by a module, the problem that the fault report of a work order generated directly is easy to cause false alarm, the generated work order elimination rate is high and the like is solved; in addition, the engineer is also lack of necessary fault diagnosis data and field auxiliary tools for maintenance, the automation degree of the diagnosis means is low, the remote problem solving rate is low, and the maintenance efficiency is not high.

In one aspect, the present invention provides a method for identifying a local fault of a terminal device, including the following steps:

step 1: acquiring a state feature code of each module in the terminal equipment in real time, monitoring whether the state of the module changes or not according to the state feature code, if so, executing the step 2, and if not, repeating the step 1;

step 2: carrying out stability detection on the module with the changed state;

judging whether the state of the changed module lasts for more than one stability detection period, if so, passing the detection and executing the step 3; if not, the detection is failed, and the step 2 is repeated;

and step 3: judging the filtering state of each module detected in the step 2 according to a preset fault filtering table, a fault grading table and a single module identification strategy;

the filtering state comprises a normal state, a fault state to be confirmed, a fault state and a fault state to be recovered;

and 4, step 4: identifying the superposition state of the terminal equipment according to a preset multi-module superposition fault strategy and the module with the detected state of normal state and fault state in the step 3, and acquiring fault field information according to the superposition state of the terminal equipment to generate fault reporting information or eliminate currently stored fault reporting information;

the method comprises the following steps that all modules in normal states and fault states are overlapped in the overlapping state of the terminal equipment, the obtained overlapping state of the terminal is identified and converted by detecting the state of the module according to step 3 based on the latest recorded overlapping state of the terminal equipment on the basis of the preset multi-module overlapping fault strategy, and the type of the overlapping state is divided into: a non-fault state, a first superposition fault state A, a second superposition fault state B, a superposition fault recovery state and a superposition fault normal preparation state;

Detailed Description

The present invention will be further described with reference to the following examples.

Example 1

As shown in fig. 1, the present invention provides a method for identifying a local fault of a terminal device, including the following steps:

step 2: carrying out stability detection on the module with the changed state;

and step 3: judging the filtering state of each module detected in the step 2 according to a preset fault filtering table, a fault grading table and a single module identification strategy; specifically, the filtering state includes a normal state, a state to be confirmed for a fault, a fault state, and a state to be recovered for a fault;

and 4, step 4: and (3) identifying the superposition state of the terminal equipment according to a preset multi-module superposition fault strategy and the module with the detected state of normal state and fault state in the step (3), and acquiring fault field information according to the superposition state of the terminal equipment to generate fault reporting information or eliminate currently stored fault reporting information.

It should be noted that the purpose of step 4 is to centrally arrange the module information of the fault status so that failure can be centrally reported. Since the module state is changed at any time, when the module state changes, that is, a part of modules is changed from normal to abnormal or from abnormal to normal, the superposition state of the terminal device changes accordingly, and therefore the latest recorded superposition state of the terminal device changes according to the module state detected in step 3.

In step 4, the process of acquiring the fault site information according to the superposition state of the terminal device to generate fault reporting information or eliminate pre-stored fault reporting information is as follows:

f 1: when the superposition state of the terminal equipment is the first superposition fault state A or the second superposition fault state B, the execution process is as follows:

firstly, judging whether fault reporting information is stored at present, if not, acquiring fault site information associated with a fault module in a first superposition fault state A or a second superposition fault state B, and generating fault reporting information according to the fault site information and the fault module in the first superposition fault state A or the second superposition fault state B;

if the fault reporting information does not cover all the fault modules in the first superposition fault state A or the second superposition fault state B, acquiring fault site information of the fault modules which are not covered, and generating new fault reporting information according to the acquired fault site information and the fault modules which are not covered; if covering, reserving the stored guarantee information;

f 2: when the superposition state of the terminal equipment is a non-fault state, eliminating currently stored fault reporting information;

In this embodiment, when generating failure reporting information, the failure field information and the failure module information are processed and executed according to the data capacity limiting policy and the module priority policy.

In this embodiment, after the failure reporting information is generated, the failure reporting two-dimensional code is generated according to the failure reporting information, and the failure reporting two-dimensional code is displayed according to a preset failure information presentation strategy, for example, a two-dimensional code picture is stored and displayed on a system desktop. And generating a two-dimensional code picture by adopting a QRCode algorithm. The display position configuration rule is that the fault two-dimensional code is dynamically configured to be displayed on a screen, the service busy and idle configuration rule is that the fault code is allowed to be displayed when the service of the equipment main application program is idle, the fault code is not allowed to be displayed when the service is busy, the display rule in different time periods is that the two-dimensional code is allowed to be displayed in a specified (configurable) time period, the temporary hidden configuration rule triggers a temporary hidden two-dimensional code for a user, the temporary hidden two-dimensional code is displayed after a period of time, and the hidden time is available.

In this embodiment, after the fault reporting information is generated, a fault reporting message is generated according to the fault reporting information, and the fault reporting message is sent to the operation and maintenance server. When fault reporting data are generated, assembling fault reporting messages and sending the fault reporting messages to an operation and maintenance background; and when the equipment state is changed into a non-fault state or the superposition fault is recovered to a normal preparation state, assembling a fault recovery message and sending an operation and maintenance background to inform operation and maintenance.

In this embodiment, the single module identification policy includes the following g1-g4 rules, the preset fault filtering table is provided with status feature codes corresponding to filterable module statuses, the fault classification table is provided with fault levels of the status feature codes, and each fault level is set to be a level which does not need to be reported or a level which needs to be reported, for example, the fault level is a fault which identifies a normal status, can automatically recover a fault, can be recovered through self-test reset of the device, or cannot be recovered.

g1 rule: and when the state feature code of the module is in a preset fault filtering table or the state feature code of the module corresponds to a fault level which does not need to be reported in a fault grading table, the module is in a normal state.

g2 rule: when the module passing the stability detection in the step 2 is converted from the normal state, the module is in a state of failure to be confirmed.

g3 rule: and when the state feature code of the module is not in a preset fault filtering table and corresponds to the fault level needing reporting in the fault grading table, the module is in a fault state.

g4 rule: when the module passing the stability detection in the step 2 is converted from the fault state, the module is in a fault to-be-recovered state.

When the filtering state of the module detected in the step 3 is a state to be confirmed by a fault or a state to be recovered by a fault, asynchronously waiting for a stability detection period, and judging whether the state to be confirmed by the fault or the state to be recovered by the fault of the module in the stability detection period is kept unchanged, if so, converting the filtering state of the module into a normal state or a fault state by the identification rule of the normal state and the identification rule of the fault state; if not, continuing to wait until the stability is satisfied and is kept unchanged in a stability detection period.

From the above, it can be seen that the filtering state of the module passing the stability detection will eventually become the normal state or the fault state according to the rule g1-g4, and the filtering state of the module is related to the aforementioned state of the same module. Based on the above g1-g4 rules, the following explanations are made for the state change rules of the same module:

as shown in fig. 2, the module initial state is a normal state, and when a change in the module state is detected, the module state changes to a fault to be confirmed state. Performing state stability filtering detection in a module fault state to be confirmed, and if the module state changes instantaneously during detection, continuing the stability filtering detection until the detection is passed; and after the diagnosis is carried out according to the rules of g1 and g3, the module state meeting the fault reporting condition is diagnosed as a fault state, and the module state not meeting the fault reporting condition is still in a completely normal state.

When the module is in a fault state, once the module state is detected to be changed and the stability detection is passed, the module state is changed into a fault to-be-recovered state. And performing state stability filtering detection in a fault to-be-recovered state, if the module state changes instantaneously during detection, continuing the stability filtering detection until the detection is passed, and diagnosing according to rules g1 and g3 after the module state passes the detection, wherein the module state which does not meet the fault reporting condition is diagnosed as a completely normal state, and the module state which meets the fault reporting condition is still in a fault state.

In this embodiment, a stacking state identification policy is set in the multi-module stacking fault policy, where the stacking state identification policy includes the following a-e rules:

a rule: and if the a1 or a2 condition is met, recording that the terminal equipment is in a no-fault state:

a 1: the terminal device never fails; a 2: the latest recorded superposition state of the terminal equipment is a superposition fault normal preparation state, and a fault module is not obtained in the step 3 in a period of completely recovering a normal detection period;

b, rule:

b 1: when the latest recorded superposition state of the terminal equipment is a no-fault state, if the module in the step 3 is in a fault state, recording that the terminal equipment is in a first superposition fault state A; b 2: when the latest recorded superposition state of the terminal equipment is a first superposition fault state A, if the state of a part of modules in the first superposition fault state A is detected to be a normal state by the step 3 and no module in the step 3 is in a fault state, recording that the terminal equipment is a new first superposition fault state A; b 3: when the latest recorded superposition state of the terminal equipment is a superposition fault recovery state or a superposition fault normal preparation state, and the superposition fault recovery state or the superposition fault normal preparation state is converted from a first fault superposition state A, if the first fault superposition state A covers the fault states of all the modules in the step 3, the terminal equipment is recorded as the first fault superposition state A;

c, rule:

c 1: when the latest recorded superposition state of the terminal equipment is a first superposition fault state A, if the first superposition fault state A does not completely contain the fault states of all the modules detected in the step 3, recording the terminal equipment as a second superposition fault state B; c 2: when the latest recorded superposition state of the terminal equipment is a second superposition fault state B, if the partial module is detected to be converted into the normal state by the step 3 when the second superposition fault state B is detected, recording that the terminal equipment is a new second superposition fault state B; c 3: when the latest recorded superposition state of the terminal equipment is a superposition fault recovery state or a superposition fault normal preparation state, if the module in the step 3 is in a fault state and does not meet the condition of B3, recording that the terminal equipment is a new second superposition fault state B;

d, rule:

d 1: when the latest recorded superposition state of the terminal equipment is a first superposition fault state A or a second superposition fault state B, if the fault module in the first superposition fault state A or the second superposition fault state B is detected to be in a normal state by the step 3, the terminal equipment is in a superposition fault recovery state;

e, rule:

e 1: and when the latest recorded superposition state of the terminal equipment is a superposition fault recovery state, if a fault module is not obtained in the step 3 in a superposition fault recovery detection period, recording that the terminal equipment is in a superposition fault normal preparation state.

According to the above a-e rule, the superimposition state of the terminal device is changed based on the superimposition state. Based on the above-described g1-g4 rule, the following change rule of the superimposition state of the terminal device is specifically explained for the state change of the plurality of modules:

as shown in fig. 3, in the present embodiment, fault reporting information corresponding to the first overlay fault state a is denoted by Qi, and fault reporting information corresponding to the second overlay fault state B is denoted by Pi;

when the terminal equipment is started for the first time, the state of the terminal equipment is initially default to a non-fault state, and fault reporting information is not generated; when any module is detected to be in fault, the superposition state of the terminal equipment is changed into a first superposition fault state A, and fault reporting information Q1 is generated; if partial modules included in the first superimposed fault state A detect that the fault state is temporarily changed to be normal, but the states of all the modules are not changed to be normal and no new fault module is added, the equipment state is still in the superimposed fault state A, and meanwhile, new fault report information Q2 is generated, wherein the new fault report information Q2 includes the fault state of the modules which are not changed to be normal;

when the equipment state is in a first superposition fault state A, any module fails, the fault state is not included in the first superposition fault state A, the terminal equipment is converted into a second superposition fault state B, and new fault reporting information P1 is generated, so that the new fault reporting information P1 includes module faults in the original fault reporting information and newly added module faults; if some modules included in the second superimposed fault state B detect that the fault state is temporarily changed to normal, but the states of all modules are not changed to normal, the equipment state is kept in the second superimposed fault state B, and meanwhile, new fault reporting information P2 is generated;

when the terminal equipment is in a first superposition fault state A, detecting that the states of all modules are temporarily changed into normal states, changing the state of the terminal equipment into a superposition fault recovery state, wherein the state lasts for one 'superposition fault recovery detection' period for the longest time, and keeping fault reporting information Q unchanged during the state duration;

when the equipment is in a superposition fault recovery state (directly converted from a first superposition fault state A), detecting that any module has a fault (the state existing in the first superposition fault state A), converting the equipment state into a superposition fault state A, and keeping original storage fault reporting information Q unchanged;

when the equipment is in a second superposition fault state B, detecting that the states of all modules are temporarily changed into normal states, and the state of the terminal equipment is changed into a superposition fault recovery state, wherein the state lasts for one superposition fault recovery detection period for the longest time; keeping the fault reporting information P unchanged during the state duration;

when the equipment is in a superposition fault recovery state and the following three scenes are a-c, the detection module is in fault, and the equipment state is changed into a new superposition fault state;

a) the superposition failure recovery state is changed from the first superposition failure state A to generate new fault reporting information P;

b) the superposition failure recovery state is changed from a second superposition failure state B, and if the module failure exists in the failure reporting information P, the failure reporting information P is kept unchanged;

c) the superposition failure recovery state is changed from a second superposition failure state B, and the module failure does not exist in the failure fault report information P,

generating fault reporting information P3;

when the equipment is in a superposition failure recovery state and the states of all modules in the equipment are normal after a superposition failure recovery detection period continues, the equipment state is changed into a superposition failure normal preparation state;

when the equipment is in a normal standby state of the superposition fault (a state which is converted from a first superposition fault state A into a superposition fault recovery state and then converted into the normal standby state), detecting that any module has a fault (a state which exists in the first superposition fault state A), and converting the equipment state into a first superposition fault state A; keeping the failure reporting information Q unchanged;

when the equipment is in a normal preparation state of the superposition fault and has the following three scenes of a-c, detecting that any module has a fault, and converting the equipment state into a second superposition fault state B;

a) if the superposition failure recovery state is changed from the superposition failure state A to the superposition failure recovery state and then to the state, generating failure fault reporting information P;

b) if the superposition failure recovery state at the moment is changed into the superposition failure recovery state from the second superposition failure state B and then is changed into the state, and the module failure exists in the failure reporting information B, the failure reporting information P is kept unchanged;

c) if the superposition failure recovery state at the moment is changed into the superposition failure recovery state from the second superposition failure state B and then is changed into the state, and the module failure does not exist in the failure reporting information B, generating failure reporting information P4;

when the terminal equipment state is in the normal preparation state of the superposition fault, and the states of all modules in the equipment are normal after a period of 'completely recovering normal detection', the equipment state is changed into a fault-free state, and the fault-reporting information is eliminated.

As can be seen from the above, the superimposition state of the terminal device changes based on the latest description of the superimposition state.
