Before new improved AFF automatic fault finding according to the present invention mechanism is described in detail, it should be noted that the associated database systems that focuses on information processing subsystem wherein and adopt with the monitoring program in the hand held computer unit of the present invention by above-mentioned skilled worker.One of these databases are knowledge or " experience " database, wherein contain rule and the static parameter of information processing subsystem for determining that its characteristic and behavior are adopted.Second database is shared database, wherein stores the initial parameter data relevant with circuit to be measured.Therefore, information processing subsystem of the present invention can constitute a kind of artificial intelligence type trouble shoot machine effectively, knowledge and experience rule in this machinery utilization knowledge data base is estimated the data that are stored in the shared database, thereby reach the action route of being recommended, this action can make the skilled worker solve the problem of pointing out in the Trouble ticket.
The present invention that accompanying drawing is drawn only demonstrates those specific detail in the function group easily.
Fig. 2 illustrates the fundamental system structure, and it comprises information processing subsystem, trouble shoot applied for machines 41 and relevant database 43 and 45.Database 43 is knowledge or " experience " database, and it contains the characteristic of definite machine 41 and the rule and the static parameter of behavior.
The algorithm and the information that are stored in the database 45 are to be application-specific, here formulate for telephone line trouble shoot purposes is special, the foundation of formulation is: the potential origin of the accurate DE of issuable all possible problem, these problems and the program for repairing circuit and therefore fixing a breakdown and recommended on the circuit.In addition, when new problem characteristic and the handling procedure relevant with these problems were known in system, knowledge data base will be changed, and comprising these information, sought applied for machines and can make more accurately when recommendation trouble shooting countermeasure and determining thereby make.
Knowledge and experience in the machine 41 employing knowledge data bases 43 is estimated the initial data in the shared database 45, solves the problem that indicates on the Trouble ticket to arrive the action route of recommending to the skilled worker.For this reason, machine 41 comprises one by (the PaloAlto of Stanford university, Cal.) applied for machines of " large program module (the Coarse Program Model) " by name that produces, this machine adopts the rule and the parameter of knowledge data base 43, set up possible fault candidate item scope, the critical point of these fault candidate item and one group of Control Parameter is relevant.Candidate item in the given range is those items that present the one or more signs that disclosed by the test parameter value.Thereafter, the testing parameter data of employing from the shared database 45 that the external source such as line test console is drawn, perhaps for example by the testing parameter data of serving expert's input, machine 41 reduces the scope of quantity to those gradually with the scope of candidate item is selected, until definite most probable candidate item that causes problem.
This process schematically is shown among Fig. 3, and this illustrates candidate point P1, P2, P3 ... the scope of Pn, these points are relevant with the various potential abnormality or the fault candidate item of the problem pointed out in the Trouble ticket that causes given circuit to be measured.In the non-limitative example of Fig. 3, P1 is relevant with earth fault for point, and P2 is relevant with right the intersecting of work (Cross toaWorking Pair) for point, and P3 is relevant with open circuit for point.
When the database of applied for machines employing is upgraded by more current information, especially, when the test result information of shared database 45 by the test result information of circuit being measured generation or application system generation, when for example the Data Dynamic that is produced by portable testing equipment is changed, machine 41 is according to this information of rule process of knowledge data base, and according to from the candidate item scope, remove those and the no longer abundant closely-related point in control point by the relation of control model regulation.At last, scope shortens single most probable fault candidate point Pm into, and machine 41 adopts this point to send treatment Countermeasures information by computer display to the skilled worker.
Fig. 4 illustrates the operating process that is used for producing according to information and feedback test the mechanism of trouble shoot countermeasure according to one embodiment of the invention.When the user to the service of sending of automation services repair systems when asking for instructions, the manager of repair systems confirms request and preparation Trouble ticket.The skilled worker is sent to ad-hoc location subsequently, will test and repair the circuit of the problem that existence reported in this position.
When arriving the job site and by being located at hand held computer unit and the wireless-wire communication subsystem in the servicer when setting up with the communicating by letter of the distant place system (central office and related data center) of necessity, as described in the people's such as Horton of above-mentioned reference the application, in step 401, the expert pack into (download) can be used for the information of Trouble ticket.
This initial program relates generally to and adopts process management application examples such as above-mentioned CAS application software, and require the technical operation testing equipment, for example SASS transmits regulating system or direct access test cell (DATU), think that the circuit that will serve provides the initial parameter data, these data can make the cause of applied for machines suspected fault.
The initial testing result of the initial information that is provided by Trouble ticket determines that for applied for machines the fault cause is enough, so can produce position and maintenance status information.Applied for machines is by carrying out external testing function and analysis subsequently and by to observation and the measurement of circuit to the response of performed program, adjusting data acquisition.For example, applied for machines can produce an instruction, asks DATU35 for instructions and opens subscriber's line 16.The response of portable testing equipment (testboard 14) to the excitation that provided by DATU is provided for it subsequently.For the example of opening subscriber's line, the voltage of portable testing equipment 14 output reading should be zero.Applied for machines subsequently according to the PTE output that monitors make next step this make and so on decision.
In step 402, the measurement data that is produced by testing equipment is packed in the shared database 45.What follow parameter testing data itself is the VER sign indicating number of being scheduled to, and this yard is relevant with the test that algorithm in adopting knowledge data base is undertaken by the mechanical type testing equipment.In case thermometrically and data are loaded program and finished, the user can see the display screen that contains choice menus, wherein may comprise other test or other function of circuit.Because applied for machines 41 produces the trouble shooting countermeasure according to the DE to effective measurement data of storing in Trouble ticket and the shared database, it is to realize the successful selection of target to menu item that technician's experience or known level will can not hinder.Although the skilled worker of different experience level can be the suitable test function menu item of Trouble ticket selection at hand easily, the setting of trouble shoot applied for machines allows that less experience person obtains guiding by the problem correction program.
For this reason, each menu screen comprises " help " an image.In step 403, when using the help image, (press pen facing to the touch screen of computer unit) by the skilled worker, applied for machines is pointed out it to the current result that obtainable information is analyzed in knowledge and shared database to user's display message, and what next step should do to recommend the expert.For this reason, use " help " image in response to the technician, in step 404, applied for machines is taken out the VER sign indicating number in the shared database of having packed into.Next step, in step 405, its explanation will be carried out any method according to the VER sign indicating number.According to institute's choosing method, will show that the indication user should do and so on information.
Especially, in step 406, the indication information relevant with the institute choosing method is shown to the user.For example, if the result that initial information that is provided by Trouble ticket and initial MLT measure be enough to the cause that is out of order, can produce position and maintenance status information this moment, on the other hand, if must further test circuit, shown information can indicate the user to implement one or more additional testings once more.That is, if desired, help/indication information screen can produce continuously, and the indication user obtains additional information by for example operational testing platform, until applied for machines with potential cause scope selected be single possible origin.
For example, suppose rising because of earth fault of the definite line fault of above-mentioned duplicate measurements and evaluation process, then may show following information: " MLT has confirmed that earth fault exists.This fault most probable occurs in the embedding cable.Adopt earth fault locator and earth gradient system (earth gradient frame) to fault location.Make the cable exposure of fault point and repair it." this information is not only represented the result that machine is analyzed Trouble ticket and test and supplemental characteristic, and is used for providing practical information (by the selection of confirming that experienced skilled worker makes, or job training is provided to less experience person) to the technician.After this, the skilled worker can implement the correction program of being advised, to remove fault.After finishing this operation, can test once more circuit, to examine maintenance status.
As can be seen from the above description, by adding in the hand held computer unit of telephone service technician according to trouble shoot of the present invention mechanism, strengthen the ability of the problem of pointing out on skilled worker's fast processing Trouble ticket of being sent to service location, and needn't consider the technical merit of service technician.By analyzing the source of multiple information, comprise that the user who comes from the skilled worker imports, dispatches the supplemental characteristic, test data and the distant place test data (by obtaining such as mechanical type go-and-return test (MLT) system) by carrying out the local test acquisition that contain in (Trouble ticket), trouble shooting of the present invention mechanism can find apace and solve countermeasure to technician's suggestion problem, and this countermeasure promptly accurately has directiveness again.
This trouble shoot mechanism is filled in telephone service expert's the hand held computer unit, makes the skilled worker can be subjected to the scheduling of Trouble ticket.By analyzing multiple information source, comprise supplemental characteristic contained in skilled worker's the user input, Trouble ticket, by carrying out test data and the remote test data that local test obtains, trouble shoot mechanism finds out and advises that problem solves countermeasure accurately.System construction comprises fault applied for machines and relevant Database Systems, and one of database is a knowledge data base, and another is shared parameter database.Knowledge data base contains the characteristic of definite applied for machines and the rule and the static parameter of behavior.These rules and information are exclusively used in the telephone line trouble shoot.
