First embodiment
Fig. 1 is the block schematic diagram of the elevator 100 with abnormity diagnosis function represented involved by the first embodiment of the present invention, shows the example being arranged on the elevator diagnosis function part 101 that the elevator control gear in elevator 100 has.
Elevator diagnosis function part 101 has unmanned test section 10, abnormity diagnosis part 20, diagnosis operation reduction part 30 and diagnosis operating instruction part 40, it is from the various sensor input sensor signal S10 of each component part being arranged on elevator, and exports diagnosis run signal S20.Elevator diagnosis function part 101 is described above, can concentrated setting on elevator control gear, and also can by the part of functions involved by each component part of elevator in whole or in part scattering device in each component part of the elevators such as lift car, governor, winch and air conditioner.
One example of the abnormity diagnosis function of elevator diagnosis function part 101 is below described.
Unmanned test section 10 is at usual run duration, and the load cell signal according to the lift car in the various sensor signal S10 of elevator detects in lift car whether be in unmanned state.At usual run duration, when being in unmanned state in lift car, abnormity diagnosis part 20 judges that the various sensor signal S10 of elevator have without exception.Diagnosis runs during the diagnosis of cutting down when part 30 is created on periodic inspection runs list and the checkup item list of carrying out the checkup item diagnosed.Specifically, diagnosis runs reduction part 30 from checkup item table (also referred to as checkup item list), deletes the checkup item being diagnosed as normal sensor signal by abnormity diagnosis part 20, or the mark deleted is set for these checkup items, its result, only be left to be diagnosed as abnormal checkup item by abnormity diagnosis part 20, so stored in advance as checkup item list by these checkup items in checkup item table.Diagnosis operating instruction part 40, when periodic inspection, send the instruction that only execution remains in the diagnosis of the checkup item in the checkup item list diagnosing operation reduction part 30 to generate, and run signal S20 is diagnosed in output.
The sensor signal S10 of elevator is the signal for controlling elevator and the signal for detecting state of elevator.As the signal for controlling elevator, in the electrical motor of winch, such as, be current value and torque value etc., in lift car, being such as load cell value etc., in elevator door, such as, is elevator door position and speed value etc.As the signal for detecting state of elevator, such as, it is the signal of sound transducer, acceleration pick-up, imageing sensor and temperature sensor etc.
In unmanned test section 10, detect in described lift car whether be in unmanned state by the combination being arranged on any one sensor in load cell, sound transducer and the imageing sensor in lift car or these sensors.When being in unmanned state, sending to abnormity diagnosis part and starting abnormality diagnostic energizing signal.
In abnormity diagnosis part 20, using from the energizing signal of unmanned test section 10 and the sensor signal S10 of elevator as input, carry out abnormity diagnosis and the result of output abnormality diagnosis.As the sensor signal S10 of elevator, in the abnormity diagnosis of winch, such as, be the torque value of the electrical motor of winch, when input value is greater than or less than the threshold value predetermined, be judged as exception.Or can adopt when carrying out the abnormity diagnosis of elevator door, in order to whether the action detecting elevator door is normal, the acceleration signal of elevator door or aud. snl. and the threshold value that predetermines are compared, when these signals are greater than or less than threshold value, be judged as abnormal method, and frequency analysis carried out to sensor values and with the statistical such as cluster or principal component analysis, the abnormal method judged is carried out to frequency values.
Diagnosis runs cuts down the abnormity diagnosis result that part 30 inputs abnormity diagnosis part 20, and has checkup item table, exports the checkup item list carrying out when periodic inspection diagnosing.
Fig. 2 represents an example of the checkup item table of the elevator 100 with abnormity diagnosis function involved by the first embodiment of the present invention.Checkup item table laterally has multiple checkup item, and these projects are by the title of object-based device, place, sensor signal and these four target configurations of diagnostic result.Diagnostic result item resets when periodic inspection, in the abnormity diagnosis carried out when nobody of usual run duration, to get beat up hook (in the table in storage area, mark is set) being diagnosed as the normal checkup item of sensor signal by abnormity diagnosis part 20.When upper once periodic inspection, the checkup item not having to tick is outputted to diagnosis operating instruction part 40 as checkup item list, diagnoses again thus.That is, tick on the diagnostic result hurdle of checkup item table, equal to delete this checkup item from checkup item list.In addition, also can not tick in diagnostic result hurdle, and it is deleted from checkup item table.
In fig. 2, the sound transducer signal of such as 1 layer of elevator door is normal, so beaten hook in the diagnostic result of the checkup item shown in this row, because this project is deleted from checkup item list, so do not diagnose this project when periodic inspection again.On the other hand, in fig. 2, the sound transducer signal of the elevator door of such as 2 layers there occurs exception, so tick in the diagnostic result of the checkup item shown in this row, because this project is still stayed in checkup item list, so diagnose again this project when periodic inspection.
During the diagnosis carried out when periodic inspection runs, omit the diagnosis that all sensor signal S10 in abnormity diagnosis are diagnosed as normal checkup item, and be only diagnosed as abnormal checkup item to sensor signal S10 in abnormity diagnosis to diagnose again, thereby, it is possible to significantly shorten the time of diagnosis operation when periodic inspection.In addition, such as, after occurring that abnormity diagnosis is carried out repeatedly to same checkup item sometimes, its diagnostic result remain sometimes for normal sometimes for abnormal situation etc., be the situation that normal checkup item is also thought to diagnose again for sensor signal S10, so also can be arranged to be diagnosed as diagnosing again at least partially of normal checkup item to sensor signal S10 in abnormity diagnosis.
At usual run duration, at nobody time, repeatedly abnormal checkup item is diagnosed as to sensor signal S10 carries out abnormity diagnosis, and during the diagnosis carried out when periodic inspection runs, be omitted in sensor signal S10 in abnormity diagnosis and become the diagnosis of normal checkup item from exception, thus, momentary exception can be got rid of, the time that diagnosis runs can be shortened when periodic inspection.
In addition, at usual run duration, part or all being repeatedly diagnosed as normal checkup item to sensor signal S10 at nobody time carries out abnormity diagnosis, and during the diagnosis carried out when periodic inspection runs, sensor signal S10 in abnormity diagnosis is diagnosed from normally becoming abnormal checkup item again, diagnose again thereby, it is possible to change abnormal checkup item into midway, can note abnormalities early.Now, the ticking cancelled from the diagnostic result normally becoming abnormal checkup item can be such as arranged in the checkup item table of Fig. 2.
As long as also can be arranged to checkup item once in abnormity diagnosis sensor signal S10 be diagnosed as normally, then this checkup item is directly deleted from checkup item list.Now, even if this checkup item is transformed into exception in midway, also diagnosis is not carried out to this checkup item when periodic inspection and run.But, after periodic inspection, need to re-start setting to checkup item list (checkup item table), so to during periodic inspection next time, if this exception exists always, then this checkup item will remain in checkup item list, so now can diagnose this checkup item again.In the case, then will postpone the period diagnosed, but if do not need the checkup item of emergency treatment, then adopt this method to set up also no problem.
Diagnosis operating instruction part 40 inputs runs the checkup item list of cutting down and generating in part 30 in diagnosis, and export diagnosis run signal S20 when periodic inspection according to this checkup item list, the diagnosis implementing elevator runs.When there occurs the exception needing emergency treatment, exporting alarm or circulating a notice of to central monitoring position.
The diagnosis carried out when periodic inspection is diagnosed the checkup item in checkup item list in running again.This is diagnosed and also carries out in elevator diagnosis function part 101.This is diagnosed and also can be held a concurrent post by abnormity diagnosis part 20, or also can be arranged to obtain sensor signal S10 by not shown diagnosis of partial again to diagnose again, or also can be obtained sensor signal S10 to hold a concurrent post by diagnosis operating instruction part 40 function of diagnosis of partial again.
Fig. 3 is the diagram of circuit of the example that the diagnosis of the elevator 100 with abnormity diagnosis function represented involved by the first embodiment of the present invention runs.
After diagnosis starts, in lift sensor signal acquisition step F 1, obtain sensor signal, and generate sensing data.
In unmanned detecting step F2, the sensing data generated and the threshold value predetermined are compared, judge whether be in unmanned state in lift car thus in step F 1.When being in unmanned state, entering abnormity diagnosis step F 3, when not being in unmanned state, returning step F 1.
In abnormity diagnosis step F 3, be used in the sensing data generated in step F 1 or the sensing data obtaining during F3 is judged as being in unmanned state in lift car and generate, carry out the abnormity diagnosis of elevator.As diagnostic method, can adopt and in abnormity diagnosis part 20, sensing data and the threshold value predetermined be compared, when these data are greater than or less than threshold value, be judged as abnormal method, and frequency analysis carried out to sensor values and with the statistical such as cluster or principal component analysis, the abnormal method judged is carried out to frequency values.
Run in reduction step F4 in diagnosis, from storage area, read checkup item table, run reduction part 30 by diagnosis and tick (mark is set) being judged as normal checkup item in step F 3.After this, return step F 1 according to necessity and repeatedly identical process is carried out to other checkup item.
When periodic inspection, when have input the energizing signal making periodic inspection start, exporting removing by diagnosis operation reduction part 30 in diagnosis before runs, having beaten the checkup item list S30 after the checkup item hooked.
