Description

  The present invention relates to a portable abnormality diagnosis device, an elevator abnormality diagnosis system, and an abnormality diagnosis method thereof, which are used in elevators and escalators, for example, to diagnose vibration and noise abnormalities.

  Generally, elevators such as elevators and escalators may generate vibration and noise during operation. Such vibration and noise not only make passengers uncomfortable, but often include some kind of failure factor. Therefore, continuing the operation of the elevator may lead to a serious failure.

  Usually, when installation of the elevator is completed, vibration and noise are measured in order to verify whether or not the installation specification conditions of the elevator are satisfied. If it is found that no vibration or noise occurs at this stage, the measurement is generally not performed thereafter. For this reason, the initial abnormalities such as vibration and noise are often overlooked. And the abnormality of a specific part may spread to other parts, and it may lead to the serious failure of an elevator.

  Therefore, in recent years, a remote maintenance system that collects elevator state data and monitors the elevator abnormality from the state data has been proposed (for example, see Patent Document 1).

  FIG. 5 shows a configuration example of a conventional elevator remote maintenance system.

  A rope 52 is stretched over the hoist 51 and a car 53 is attached to one end thereof, and a counterweight 58 is attached to the other end. The car 53 moves up and down via the rope 52 by driving the hoisting machine 51.

  Here, an acceleration sensor 54 for detecting vibration data during traveling is installed on the floor surface of the car 53. The vibration data detected by the acceleration sensor 54 is sent to the control panel 56 via the tail code 55 and then transmitted from the control panel 56 to the service center 57 via the telephone line.

The service center 57 includes a main computer 59. The main computer 59 analyzes the vibration data of the car 53 and determines whether there is an abnormality in the elevator based on the analysis result.
Japanese Patent Laid-Open No. 2001-341156 (FIG. 3)

  As described above, in the conventional remote maintenance system, the acceleration sensor 54 is permanently installed on the car floor of the car 53. For this reason, the vibration state of the car 53 can be constantly monitored.

  However, when some abnormality occurs, that is, when a large vibration is detected by the acceleration sensor 54, the cause cannot be determined only by the vibration detection location. In this case, if the acceleration sensor 54 is installed in each part of the elevator including the car 53, the cause can be determined accurately, but there is a problem that the price of the whole elevator is increased.

  The maintenance service center 10 comprehensively manages the work schedule and work results of workers. A maintenance service management DB (database) 21 is connected to the maintenance service center 10.

  The maintenance service management DB 21 includes a work schedule data unit 21a and a work result history data unit 21b. The work schedule data section 21a stores, for example, data such as work date and time, worker name and ID, and building ID. In addition, data such as the machine ID, presence / absence of abnormality, and date and time of completion of maintenance may be added. In the work result history data section 21b, data such as a machine ID, an abnormality occurrence measurement date and time, an abnormal part, a part, and the presence / absence of a part are stored for each building.

  In addition, when the data recording part 23 receives the data with replacement parts, it records the data to that effect in the parts presence / absence area of the work result history data part 21b.

  Next, the operation of the elevator abnormality diagnosis system of the present invention will be described.

  FIG. 4 is a flowchart showing a processing procedure of the elevator abnormality diagnosis system of the present invention.

  At the time of regular inspection or when there is a report of an abnormality from the elevator manager, the worker goes to the elevator installation site with the portable abnormality diagnosis device 12. At the elevator installation site, the maintenance worker connects the acceleration sensor 13 to the portable abnormality diagnosis device 12. The acceleration sensor 13 is installed on the floor surface of the car 3, for example, so that the car 3 runs.

  At this time, a measurement location is input to the portable abnormality diagnosis device 12 by a predetermined operation. For example, when the acceleration sensor 13 is installed on the floor surface of the car 3, “car floor” is input as the measurement location. Thereby, the portable abnormality diagnosis device 12 executes the following process.

  That is, the portable abnormality diagnosis device 12 takes in vibration data of the measurement location from the acceleration sensor 13, and performs a high-speed Fourier transform or wavelet transform in the measurement data analysis unit 15 to analyze the frequency component of the vibration data (S1: Data analysis step).

  Next, the portable abnormality diagnosis device 12 provides the abnormality diagnosis unit 16 with the frequency component of the vibration data obtained as an analysis result by the measurement data analysis unit 15. The abnormality diagnosis unit 16 refers to the abnormality diagnosis data storage unit 14 to determine whether or not the frequency component of the vibration data obtained as the analysis result is within the range of the abnormal frequency at the measurement location ( S2: Abnormal diagnosis step). More preferably, it is determined whether or not the car 3 is within the range of the abnormal frequency in consideration of the driving state.

  When the frequency component of the vibration data obtained as a result of the analysis is within the range of the abnormal frequency, the abnormality diagnosis unit 16 diagnoses that there is an abnormality. When there is an abnormality, the abnormality diagnosis unit 16 searches the abnormality diagnosis data storage unit 14 for the part or location that caused the occurrence of the abnormality corresponding to the abnormal frequency range. The searched cause component or location of the occurrence of the abnormality is displayed on the display unit 19 through the diagnosis result output unit 17 (S3: diagnosis result output step).

  In this way, simply by installing the acceleration sensor 13 connected to the portable abnormality diagnosis device 12 at an arbitrary location such as a car floor, the presence or absence of abnormality can be easily determined from the traveling vibration waveform measured by the acceleration sensor 13. Diagnosis is possible, and furthermore, the part or location that caused the abnormality can be quickly clarified.

  Moreover, even if the worker does not have special knowledge or experience to analyze the traveling vibration waveform of the elevator, it is possible to reliably detect abnormal parts and abnormal parts of the elevator.

  In addition, when there is an abnormality, a part or a part estimated as the cause of the abnormality is displayed on the display unit 19. Therefore, if the acceleration sensor 13 is installed at the displayed part or location and the vibration waveform is measured using the portable abnormality diagnosis device 12 in the same manner as described above, a more accurate abnormality determination can be performed. As a result, depending on the degree of abnormality, for example, the abnormality can be easily resolved at that place only by simple adjustment such as retightening the screw.

  Further, when replacement of parts is necessary, the maintenance service center 10 can be inquired for replacement parts by connecting the portable abnormality diagnosis device 12 to the control panel connection terminal 6.

  In this case, according to the operation of the worker, data for inquiring whether or not there is a replacement part is transmitted from the transmission / reception unit 18 of the portable abnormality diagnosis device 12 together with the abnormal part data including the worker ID, the building ID, and the machine ID. The data transmitted from the transmission / reception unit 18 is given to the control panel 7 via the tail code 8 and then transmitted from the control panel 7 to the maintenance service center 10 via the transmission line 9.

  When the maintenance service center 10 receives the inquiry data on the presence / absence of replacement parts accompanied by abnormal part data via the transmission / reception unit 22, the maintenance service center 10 performs the following processing.

  That is, the maintenance service center 10 first compares the worker ID stored in the work schedule data unit 21a of the maintenance service management DB 21 with the worker ID included in the received data through the data recording unit 23, and creates a regular one. Check if the inquiry is from a worker. If it is an inquiry from a regular worker, data is recorded in each item of the machine ID, abnormality occurrence measurement date and time, and parts / location in the work result history data portion 21b of the corresponding building ID.

  Next, the maintenance service center 10 executes the part presence / absence confirmation unit 24. The part presence / absence confirmation unit 24 confirms the presence / absence of a replacement part by transmitting inquiry data about the presence / absence of a replacement part including the building ID and the machine ID to the part center 11 via the transmission / reception unit 25 (S4: Part presence / absence confirmation). Step).

  The parts center 11 stores parts inventory list data. The parts center 11 checks the inventory status of the parts using the parts inventory list data, and notifies the maintenance service center 10 of the result. In addition, if there is a stock of parts, it is decided whether to deliver to the site by the normal route, the emergency route, or to delegate the parts delivery to the maintenance service center 10 based on the building ID and the unit ID. The result is transmitted to the maintenance service center 10.

  Here, when the maintenance service center 10 receives data from the component center 11 via the transmission / reception unit 25 and the component presence / absence confirmation unit 24, the component-related data creation unit 26 creates the component-related data and the portable abnormality diagnosis device 12. (S5: component-related data creation step). This part-related data includes, for example, parts replacement work procedure data obtained from the maintenance service management DB 21 in addition to replacement parts inventory data and delivery status data (normal delivery / emergency carry-in / part arrangement, etc.).

  When the portable abnormality diagnosis device 12 receives the component-related data from the maintenance service center 10, it displays it on the display unit 19 (S6: component-related data display step). From this display content, it is possible to confirm the presence / absence of replacement parts, delivery status, part replacement procedure, and the like.

  As described above, when the parts need to be replaced, the portable abnormality diagnosis device 12 is connected to the control panel connection terminal 6 and inquiry data on the presence / absence of replacement parts is transmitted to the maintenance service center 10 by a predetermined operation. The maintenance service center 10 checks the inventory status of the parts center 11 and returns data such as the presence / absence of the replacement parts, delivery status, and replacement work procedure to the portable abnormality diagnosis device 12.

  Therefore, the worker at the site can check the presence or absence of replacement parts on the spot. In the case of urgent necessity, if the data to that effect is transmitted to the maintenance service center 10, the parts can be received and replaced at the site.

  Further, since the worker obtains the data of the replacement work procedure for the part, the part can be replaced smoothly and without error. Note that the data of the replacement work procedure includes not only a part replacement work but also data related to an abnormal part adjustment work.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  (1) In the above embodiment, since the minimum data for performing abnormality diagnosis is set in the abnormality diagnosis data storage unit 14, for example, even when abnormal vibration occurs, the abnormality diagnosis data is stored in the abnormality diagnosis data storage unit 14. Not applicable.

  Therefore, if the cause of the abnormality cannot be identified, put a putty if the vibration measurement method (for example, indication of measurement position, selection of a different conversion method, etc.) or the inspection method for the abnormal part (for example, SHEAVE) is unbalanced. It is also possible to provide a guidance function relating to a method for adjusting an abnormal point (for example, increasing or decreasing the control gain of the control panel). In this way, the abnormality diagnosis result can be further improved, and the abnormality can be quickly resolved on site.

  (2) In the above embodiment, a dedicated device is used as the portable abnormality diagnosis device 12. However, a general-purpose notebook computer having the same software function as in FIG. 2 may be used. That is, in recent years, portable notebook personal computers have become mainstream as personal computers and can be used as the portable abnormality diagnosis device 12.

  (3) Furthermore, although the said embodiment connected the acceleration sensor 13 to the portable abnormality diagnosis apparatus 12, and measured the vibration data in the arbitrary places of an elevator, it replaces with the acceleration sensor 13 and the sensor which measures noise is used, for example. A configuration may be employed in which abnormality diagnosis is performed by measuring noise data at an arbitrary location of the elevator in the same manner.

  Further, if an abnormality diagnosis is performed by alternately or simultaneously connecting an acceleration sensor 13 and a noise sensor (not shown) to the portable abnormality diagnosis device 12, an abnormal part or an abnormal part can be specified more accurately. .

(4) Furthermore, it goes without saying that the present invention can be easily applied not only to elevator abnormality diagnosis, but also to escalator abnormality diagnosis.
