Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Figure 1 shows that the process flow diagram of the distribution terminal self-diagnosing method in an embodiment, comprise the following steps:
S110, detects the running status of distribution terminal, and generates state indieating variable according to the running status of distribution terminal.
Constantly the running status of the trouble spot of easily breaking down in distribution terminal detected thus state indieating variable can be generated according to the running status detected.State indieating variable is used for whether there is fault to the fault type of distribution terminal and the fault type of correspondence and carries out record.In the present embodiment, state indieating variable is binary number, its each corresponding a kind of fault type, and each has two state values i.e. the first state value and the second state value.Wherein, there is the fault of this fault type for representing in the first state value, the second state value then for representing the fault that there is not this fault type, i.e. this trouble shooting.Particularly, place value represents the first state value for " 1 ", and place value " 0 " then represents the second state value, namely when the place value of a certain position inquiring state indieating variable is " 1 ", then can judge that distribution terminal exists the fault of the type.In the present embodiment, state indieating variable can change with the change of the running status of distribution terminal.Particularly, when some trouble spots of distribution terminal break down or trouble shooting time system all can the abnormality alarming interface function of this fault point of Automatically invoked to state indieating variable in represent the binary digit of this fault type position change, thus the state indieating variable of making can reflect the running status that distribution terminal is current.
S120, obtains state indieating variable and is stored in the first buffer zone by state indieating variable.
The state indieating variable got is stored in the first buffer zone temporarily, to call it in follow-up self diagnosis process.
S130, judges that whether the content of the first buffer zone is identical with the content of the second buffer zone.
The state indieating variable generated during one-time detection before second buffer zone is used for interim storage.Therefore can judge whether the running status of distribution terminal there occurs change, namely whether has occurred new fault or has had Failure elimination by judging that whether the content of the first buffer zone is identical with the content of the second buffer zone.When the content of the first buffer zone is identical with the content of the second buffer zone, then returns and perform the self diagnosis process that step S110 enters next round.When the content of the first buffer zone is not identical with the content of the second buffer zone, then represent that the running status of distribution terminal there occurs change, then execution step S140 and thereafter step.In the present embodiment, before execution step S110, also can carry out initialization to the first buffer zone and the second buffer zone, the two is set to have identical content, the value being about to the state indieating variable stored in the two is set to identical (being 0).
S140, stores the current operating condition of distribution terminal and forms operating mode daily record.
Because the running status of distribution terminal there occurs change, therefore need current operating condition to be carried out storage and form operating mode daily record, so that staff checks, comprehensively understand the running status of distribution terminal in time, thus corresponding operational processes can be carried out according to its state, guarantee the normal operation of equipment to greatest extent.Traditional distribution terminal is only when equipment breaks down, still the operating condition after Failure elimination can't be stored in operating mode daily record by it operating condition during fault to be carried out storing the daily record of formation operating mode, therefore it can not show fault and eliminates in operating mode daily record, still show fault, be not easy to the true operation conditions that staff understands equipment.Operating condition, when trouble shooting or fault cause the running status change of distribution terminal, all can be stored in operating mode daily record, thus can be good at solving this problem by this method.
In the present embodiment, the operating mode journal file of preservation adopts CSV format, and it can be checked by a lot of program, thus facilitates staff's checking operating mode daily record.Its operating mode journal file of traditional distribution terminal adopts dat form, only checks by specific program.In the present embodiment, the operating condition stored is needed to comprise the contents such as the task ID of operating mode, operating mode date, operating mode time, operating mode type and operating mode description occur.In the present embodiment, the idiographic flow of step S140 as shown in Figure 2, comprises the following steps.
S210, obtains the first file size.
First file is for storing the operating condition record of distribution terminal.
S220, judges whether the size of the first file is more than or equal to preset value.
In traditional distribution terminal, the file preserving operating mode daily record has threshold limit value, can not continue to preserve when exceeding this threshold limit value, stores after needing file to empty again.In the present embodiment, the size of preset value can set as required, can adopt traditional file threshold limit value.When judging that the size of the first file is more than or equal to preset value, performing step S230 and S240, otherwise then performing direct step S240.
S230, carries out rename as the first file newly-built after the second file to the first file.
When the size of the first file is more than or equal to preset value, when namely the first file storage has been expired, rename is carried out as the second file and newly-built first file to the first file.Such as, by the first file A RNTO B, more newly-built first file A, thus guarantee that operating condition record can carry out strict storage according to the sequencing of generation time, be convenient to checking of staff.
S240, is stored in operating condition current for distribution terminal in the first file.
Operating condition storing process is stored in one by one from top to bottom in the first file according to the sequencing of its generation time.
In one embodiment, when the first file stores full, can using the first file rename after the second file again by newly-built first file, thus new operating condition record to be stored in the first file.Therefore, when memory block exists the second file, the time that the operating condition record in the second file produces, the signal of its storage direction as shown in Figure 3 early than the operating condition record in the first file.
In the present embodiment, when reading operating condition record, first obtain the total number n that the first file is current, in case after clicking, the first file continues to preserve working state recording, affects the reading of data.Can read successively, until read whole data of the first file from a record of up-to-date preservation in file reading process.If there is the second file, need the total number of acquisition first file and the second file, then first read the data of the first file, after the first file runs through, then read the data of the second file, until read the data of full needs.
In the present embodiment, also can show by the operating condition current to distribution terminal.System can by the display of operating condition record on the display panel.Procedure for displaying shows according to the sequencing of time, and override shows emerging operating condition record, thus is convenient to staff and grasps the up-to-date operation conditions of distribution terminal.
S150, compares the state indieating variable in the first buffer zone and the second buffer zone thus the fault type determining to cause the running status of distribution terminal to change determine the fault level of this fault type.
In the present embodiment, the state indieating variable compared in the first buffer zone and the second buffer zone compares each in state indieating variable successively, thus orient the fault type that place value changes, namely determine the fault type causing the running status of distribution terminal to change.By only operating the fault type that there is change, can avoid carrying out repetitive operation to those in the fault that repeatedly self diagnosis process all exists and causing operating mistake.Further, only the fault that emerging fault or new explanation are removed is processed accordingly, the operating efficiency of self diagnosis can be improved.
The fault level that fault type is corresponding be people for presetting, it is stored in advance in distribution terminal by the form of form.Therefore, after determining the fault type that the running status that causes distribution terminal changes namely by inquiry fault type grade classification form to determine the fault level of this fault type.Wherein, fault type grade classification form is as shown in table 1, and in the present embodiment, fault level comprises the first estate, the second grade, the tertiary gradient and the fourth estate, and its fault severity level increases successively.In other examples,
The own situation of bonding apparatus can carry out grade classification.
Table 1: fault type grade classification table
S160, the fault level according to fault type processes accordingly to distribution terminal.
After determining the fault level that fault type is corresponding, according to its fault level, distribution terminal is processed accordingly.In the present embodiment; fault level comprises four; therefore different operations can be carried out according to four grades; fault for especially severe just carries out latch-up protection output; then alarm prompt is provided for other faults; thus ensure that the normal operation of equipment to greatest extent, ensure people life and produce normally carry out.The idiographic flow of step S160 as shown in Figure 4, comprises the following steps.
S410, whether the fault level of failure judgement type is greater than the first estate.
If the fault level of fault type is the first estate, then returns and perform step S110, start next round self diagnosis process.Staff by checking that operating mode daily record can judge to occur which kind of fault distribution terminal exists, thus processes accordingly to fault, makes equipment return to normal operating condition.
If the fault level of fault type is more than the second grade, then perform step S420.
S420, stores this Reflector after the place value representing this fault type is assigned to zone bit corresponding with this fault type in Reflector in state indieating variable.
When fault level is more than the second grade, when namely fault level is the second grade, the tertiary gradient or the fourth estate, the position representing this fault type in state indieating variable is assigned to zone bit corresponding with this fault type in Reflector.Reflector is used for carrying out record to the fault type of fault level more than the second grade.In the present embodiment, state indieating variable only stores with buffer zone temporarily, can't form the output of remote measurement value and check for staff; Reflector then can form remote measurement value and export and carry out checking for staff and position fault fast and carry out the operations such as maintenance to fault afterwards.
In the present embodiment, Reflector adopts the binary number of 32 to store, its each represent a kind of fault type, each has two state values equally, i.e. the first state value and the second state value.It wherein represents when the first state value is " 1 " and breaks down, and the second state value is that " 0 " then represents do not have fault, and the corresponding relation of each zone bit and fault type is as shown in table 1.Therefore, when a failure occurs it, staff only needs to check that who zone bit becomes " 1 " and can find trouble spot by the table of comparisons 1, thus realizes the quick position to trouble spot, improves maintenance efficiency.
S430, whether the fault level of failure judgement type is greater than the second grade.
If when the fault level of fault type is greater than the fault of the second grade, perform step S440, otherwise then return execution step S110, re-execute the self diagnosis process of next round.
S440, whether the place value of zone bit corresponding with this fault type in failure judgement mark is the first state value.
When judging that fault type is greater than the second grade, namely fault type be the tertiary gradient or the fourth estate time, whether the place value representing the zone bit of this fault type in further failure judgement mark is the first state value (whether there is fault), if then perform step S450, as otherwise perform step S455.In other examples, this step also can by judging whether the position of the binary digit that state indieating variable is corresponding with this fault type is that the first state value judges whether to there is fault.
S450, lights alarm indicator.
In the present embodiment, system panel is provided with an alarm indicator.When occurring the fault type being greater than the second grade, and when the place value of zone bit corresponding with this fault type in Reflector is the first variable, representing the fault occurring the type, lighting alarm indicator, send prompting warning to staff.
S455, extinguishes alarm indicator.
When occurring the fault type being greater than the second grade, and when the place value of zone bit corresponding with this fault type in Reflector is the second variable, representing the trouble shooting of this fault type, therefore extinguishing alarm indicator, this trouble shooting of prompting staff.
S460, whether the fault level of failure judgement type is greater than the tertiary gradient.
In the present embodiment, also need to perform step S460 and subsequent step after execution of step S450 or S455.Due in the fault type being greater than the second grade, also may have the fault type of the fourth estate except the fault type of the tertiary gradient, therefore need the fault type judging whether further to there is the fourth estate.
If there is not the fault that fault level is greater than the tertiary gradient, when namely there is not the fault type of the fourth estate, return and perform step S110, re-execute the self diagnosis process of next round.If there is the fault that fault level is greater than the tertiary gradient, when namely there is the fault of the fourth estate, also need to perform step S470 or step S475 further.
S470, latch-up protection exports.
When fault level is greater than the tertiary gradient and the place value of zone bit corresponding with this fault type in Reflector is the first state value, when namely the fault of the fourth estate occurs, needs to carry out latch-up protection output, distribution terminal is protected.
S475, terminates latch-up protection.
When fault level is greater than the tertiary gradient and the place value of zone bit corresponding with this fault type in Reflector is the second state value, i.e. the trouble shooting of the fourth estate, need to carry out end latch-up protection, thus ensure the normal operation of equipment to greatest extent.
S170, is assigned to the second buffer zone by the content of the first buffer zone.
After execution of step S470 and S475, the content of the first buffer zone is assigned to the second buffer zone, thus in the self diagnosis process of next round, new state indieating variable can be stored in the first buffer zone.Complete S170 and namely complete epicycle self diagnosis process, return the self diagnosis process that step S110 reenters next round.
Above-mentioned distribution terminal self-diagnosing method running status change namely break down and trouble shooting time all can carry out storages formation operating mode daily record to status condition, therefore can demonstrate fault whether to eliminate in operating mode daily record, be convenient to staff and understand the operation conditions of distribution terminal thus carry out the normal operation that corresponding operating ensures equipment.Said method can also process distribution terminal according to fault level automatically accordingly according to after fault type determination fault level simultaneously, thus ensures the normal operation of distribution terminal to greatest extent.
