FIG. 2 is a flowchart showing processing of the maintenance work support system according to the embodiment. FIG. 3 is a block diagram of a maintenance work support system according to a modification of the present invention.

Hereinafter, a maintenance work support system (hereinafter simply referred to as a maintenance work support system) for a lifting apparatus according to the present invention will be described. The maintenance work support system is a system that supports maintenance work of the lifting device using a technician portable terminal (hereinafter simply referred to as a portable terminal) by a technician. This maintenance work support system is performed as a stage before the maintenance work of the lifting device using the portable terminal is started by a technician. In the maintenance work support system, when a failure signal is output from the lifting device, the mobile terminal outputs maintenance work information corresponding to the event code. Thereby, the technician who possesses a portable terminal can perform the maintenance work of the lifting device based on the maintenance work information.
In addition, although there exist an elevator, an escalator, etc. in a raising / lowering apparatus, below, the maintenance work assistance system containing the portable terminal which maintains an elevator is demonstrated. The maintenance work of the elevator includes, for example, maintenance support such as inspection of the guide rail and maintenance of the car door and failure response such as repair of the car door.

  As shown in FIG. 1, the maintenance work support system includes an elevator 2 having a control microcomputer 21 that outputs an event code, a server 4 connected to the control microcomputer 21, and a portable terminal 3 that can be connected to the server 4. . In the maintenance work support system 1 of this embodiment, the server 4 includes a first server 5 and a second server 6 that is connected to the first server 5 and includes a storage unit 60.

  The elevator 2 includes an operation unit 20 having a car or the like that moves in a hoistway, a control microcomputer 21 that outputs a failure signal and an event code, and a photographing machine 22 such as a camera that photographs the inside of the car.

  Specifically, the failure signal output from the control microcomputer 21 is a signal output from the control microcomputer 21 and indicating the failure when a failure occurs in the elevator 2. The failure of the elevator 2 here is a failure of a car door or a landing door, a life of a car illumination, or the like. Hereinafter, the elevator 2 that has output the failure signal is referred to as a warning elevator.

  The event code output from the control microcomputer 21 is a code associated with the operation status of the elevator 2 itself. Specifically, the event code indicates car position information, car door opening / closing information, motor drive information, and the like. In the maintenance work support system 1 of the present embodiment, event codes output according to the status of the operation unit 20 are stored in a memory in the control microcomputer 21. The accumulated event code can be acquired by the mobile terminal 3 or the server 4.

  The control microcomputer 21 is connected to the server 4 via the communication system R1. For example, the communication system R1 can communicate with the server 4 via the remote monitoring unit 7 and the telephone line in order from the control microcomputer 21, and conversely from the server 4 via the telephone line and the remote monitoring unit 7. This is a communication system that can communicate with the microcomputer 21. The control microcomputer 21 outputs a failure signal and an event code to the server 4 via the communication system R1.

  In the maintenance work support system 1 of the present embodiment, the photographing machine 22 is connected to the server 4 via a telephone line. The photographing machine 22 outputs, for example, image information in the car or the like to the server 4 as one piece of status information of the elevator 2. For example, the control microcomputer 21 outputs various log data to the server 4 as one of the status information of the elevator 2.

  The portable terminal 3 is, for example, a PDA (Personal Digital Assistant), a notebook personal computer, or the like. Specifically, the portable terminal 3 is used when maintenance work of the elevator 2 is performed by a technician. In addition, the technician who possesses the portable terminal 3 stays in the vicinity of the elevator 2 that is a target of the maintenance work when the maintenance work of the elevator 2 is performed. In FIG. 1, mobile terminals 3 </ b> A and 3 </ b> B are shown as two mobile terminals 3, but only one mobile terminal 3 may exist, or three or more mobile terminals 3 may exist. Good.

  The portable terminal 3 can be connected to the server 4 (for example, the first server 5) via the communication system R2. The communication system R2 can communicate with the server 4 (for example, the first server 5) from the portable terminal 3 via the Internet, for example, and the portable terminal from the server 4 (for example, the first server 5) via the Internet. 3 is a communication system capable of communication.

  The portable terminal 3 includes an output unit 30 that outputs information output from the server 4 or information stored in the server 4 (for example, maintenance work information 601 and a check list 602) in a state where communication with the server 4 is possible. . In the maintenance work support system 1 of the present embodiment, the output unit 30 is a display unit such as a display for outputting image information.

  The server 4 includes the first server 5 and the second server 6 as described above. The server 4 is installed in, for example, a monitoring center that is a building apart from the elevator 2.

  The second server 6 includes a storage unit 60 that stores a database 600, maintenance work information 601, and a check list 602. The second server 6 is connected to the first server 5 by wire, for example, P2P. The second server 6 is connected to the mobile terminal 3 via the communication system R3. For example, the communication system R3 can communicate with the mobile terminal 3 sequentially from the second server 6 via the first server 5 and the Internet, and conversely from the mobile terminal 3 via the Internet and the first server 5. This is a communication system capable of communicating with the second server 6.

  The maintenance work information 601 here is a procedure manual that sequentially shows work to be performed when one maintenance work (for example, maintenance of a car door) is performed. The check list 602 corresponds to the maintenance work information 601 and is a check list for preventing work leakage during maintenance work. Specifically, the check list 602 is a check list that is checked each time the work described in the maintenance work information 601 is performed when the maintenance work of the elevator 2 is performed. Although only one maintenance work information 601 is shown in FIG. 1, the actual storage unit 60 stores a plurality of maintenance work information 601. The same applies to the check list 602, and the actual storage unit 60 stores a plurality of check lists 602.

  In the maintenance work support system 1 of the present embodiment, the database 600 is a database related to information in which event codes are associated with maintenance work information. For example, the database 600 stores the address of the maintenance work information 601 corresponding to the event code in the storage unit 60 and the addresses of a plurality of checklists 602 corresponding to the event code in the storage unit 60. The address of the maintenance work information 601 is an address where the maintenance work information 601 is stored in the storage unit 60, that is, a storage destination address of the maintenance work information 601. Similarly, the address of the check list 602 is a storage destination address of the check list 602 in the storage unit 60.

  For example, since at least one maintenance work information 601 corresponds to one event code, and one address corresponds to one maintenance work information 601, in the database 600, at least one maintenance code 601 corresponds to one event code. The address of the maintenance work information 601 corresponds. In addition, since one check list 602 corresponds to one maintenance work information 601 and one address corresponds to one check list 602, in the database 600, at least one check is included in one event code. The addresses in the list 602 correspond to each other.

  Further, the database 600 applies the information regarding the priority order to which the at least one maintenance work information 601 corresponding to one event code is applied and the at least one check list 602 corresponding to one event code. Information on priority order to be stored is stored.

  The first server 5 includes a CPU (Central Processing Unit) and the like. In the first server 5, the processing unit 50 is functionally formed by the CPU executing a predetermined program.

  The processing unit 50 constantly checks whether or not a failure signal is output from the control microcomputer 21. When the processing unit 50 confirms that the failure signal has been output, the processing unit 50 acquires an event code when the failure signal is output (at the time of reporting) from the control microcomputer 21. In the maintenance work support system 1 of the present embodiment, the processing unit 50 acquires the status information of the elevator 2 together with the event code. The situation information is, for example, image information photographed by the photographing machine 22 or log data acquired by the control microcomputer 21.

  The processing unit 50 estimates the cause of the event code based on the acquired event code and the status information (for example, image information and log data) of the elevator 2. Therefore, the estimated cause of the event code is an estimated cause based on the event code, an estimated cause based on the image information, and an estimated cause based on the log data.

  Specifically, the processing unit 50 acquires image information such as in the car as the status information of the elevator 2 from the photographing machine 22. By performing image recognition on image information in the car or the like, for example, the presence or absence of a person in the car can be determined. When the car is manned, it may be estimated that the cause of the event code is artificial. Specifically, if the person who can open the car door can be confirmed by performing image recognition on the image information in the car, it is estimated that the cause of the event code is the artificial car door opening. Can do.

  The log data acquired by the control microcomputer 21 is, for example, data such as a car speed, car acceleration, car brake timing, a motor torque command provided in a hoistway, and a power source relay. . For example, when the log data is the speed of the car, if the waveform indicating the change in the car speed over time deviates more than a certain amount from the range of the regular waveform (normal waveform), the cause of the event code is It can be estimated that the speed of the car is abnormal. If the log data is the acceleration of the car, and the waveform indicating the change in the acceleration of the car over time is not gentle, it can be estimated that the cause of the event code is an abnormality in the acceleration of the car.

  The processing unit 50 extracts information related to the maintenance work information 601 corresponding to the event code acquired from the control microcomputer 21 and information related to the check list 602 based on the database 600. Specifically, the processing unit 50 extracts the address of the maintenance work information 601 corresponding to the acquired event code and the address of the check list 602 from the database 600 of the storage unit 60. Further, the processing unit 50 outputs these addresses to the mobile terminal 3A.

  The processing unit 50 designates the portable terminal 3 corresponding to the notification elevator. In the maintenance work support system 1 of the present embodiment, since the engineer in charge of the maintenance work of the reporting elevator has the portable terminal 3A, the processing unit 50 can change the portable terminal 3A (mobile station 3A (reporting elevator maintenance work) from the portable terminals 3A and 3B. The portable terminal 3A) possessed by the technician in charge is designated. Specifically, in the first server 5, information on a technician in charge of maintenance work of the elevator 2 and information on the portable terminal 3 possessed by the technician are stored, and the processing unit 50 stores information on the portable terminal 3A. Extraction is possible. In the maintenance work support system 1 of the present embodiment, since the server 4 and the mobile terminal 3 are connected via the Internet, the information of the mobile terminal 3 is, for example, the IP address of the mobile terminal 3.

  The processing unit 50 applies the event code, the estimated cause of occurrence, the address of the maintenance work information 601, the priority for applying the maintenance work information 601, the address of the check list 602, and the check list 602 to the designated mobile terminal 3 </ b> A. Various information such as priority and status information (for example, image information and log data) is output.

  The communication systems R1, R2, R3, and the other communication systems are each a communication system having a general configuration (a communication system including a part or all of a modem, a DSU (Digital Service Unit), a wired line, a wireless line, etc.). is there. In the maintenance work support system 1 of the present embodiment, a part of the communication systems R2 and R3 (Internet) is common, but the communication systems R2 and R3 are other communication systems in which neither part is at all common. There may be.

  Hereinafter, the flow of processing in the maintenance work support system 1 will be described with reference to the flowchart of FIG.

  The processing unit 50 constantly monitors the output of the failure signal from the control microcomputer 21 (reporting of the elevator 2), and when there is no failure signal from the control microcomputer 21 (No in S01), the processing unit 50 is in a standby state until the failure signal is confirmed. It has become.

  When there is a failure signal from the control microcomputer 21 (Yes in S01), the processing unit 50 obtains an event code from the control microcomputer 21, and as the status information of the elevator 2, image information such as the car interior from the photographing machine 22 is acquired. The log data is acquired from the control microcomputer 21 (S02). The processing unit 50 estimates the cause of occurrence of the event code from the event code and status information (for example, image information and log data) (S03).

  When the estimation of the cause of occurrence of the event code is completed, the processing unit 50 extracts information on the maintenance work information 601 and information on the check list 602 using the database 600 (S04). Specifically, the processing unit 50 extracts, from the database 600, the address of the area in the storage unit 60 in which the maintenance work information 601 corresponding to the event code and the check list 602 are stored.

  The processing unit 50 designates the portable terminal 3A corresponding to the notification elevator (S05), and assigns an event code, an estimated cause of occurrence, an address of the maintenance work information 601, an address of the check list 602, and status information to the portable terminal 3A. (For example, image information acquired from the camera 22 and log data acquired by the control microcomputer 21) are output. The portable terminal 3A receives the output of the maintenance work information 601 and the address of the checklist 602 from the processing unit 50, and corresponds to the output address in the storage unit 60 of the second server 6 via the communication system R3. The maintenance work information 601 and the check list 602 to be referred to are referred to. The output unit 30 of the portable terminal 3A includes an event code output from the processing unit 50, an estimated cause of occurrence, status information, a priority order to apply the maintenance work information 601, and a priority order to apply the check list 602. The reference destination maintenance work information 601 and the check list 602 are output.

  As described above, in the maintenance work support system 1, the storage unit 60 stores the maintenance work information 601 corresponding to the event code, and the portable terminal 3 </ b> A maintains the maintenance work information corresponding to the event code output from the control microcomputer 21. 601 is output. Therefore, a technician who possesses the mobile terminal 3A can perform maintenance work of the elevator 2 appropriately and quickly based on the output maintenance work information 601 regardless of the skill level of the technician.

  Further, in the maintenance work support system 1, the storage unit 60 stores a database 600 related to information in which event codes and maintenance work information 601 are associated with each other, and the mobile terminal 3 </ b> A stores the database 600 stored in the storage unit 60. Is used to extract the maintenance work information 601 corresponding to the event code from the control microcomputer 21 and output the extraction result. Therefore, it is not necessary for the mobile terminal 3A to store the maintenance work information 601, and the memory capacity of the mobile terminal 3A can be suppressed.

  In the maintenance work support system 1, the first server 5 acquires an event code corresponding to the time of issue from the control microcomputer 21. Therefore, a technician who possesses the mobile terminal 3A can check the maintenance work information 601 corresponding to the event code at the time of failure of the elevator 2 (at the time of reporting). As a result, this technician can perform maintenance work on the elevator 2 based on the maintenance work information 601 suitable for the failure of the elevator 2.

  In the maintenance work support system 1, the server 4 acquires the event code and the status information of the elevator 2 (for example, image information output from the photographing machine 22 and log data acquired by the control microcomputer 21), The cause of the event code obtained based on these is estimated. The portable terminal 3A outputs the cause of occurrence of the event code estimated by this server, so that the technician who possesses the portable terminal 3A can confirm the cause of occurrence of the event code estimated by the server. Therefore, this technician can perform the maintenance work of the elevator 2 based on the cause of the event code in addition to the maintenance work information 601.

  In the maintenance work support system 1, the portable terminal 3 </ b> A is acquired by the status information of the elevator 2 (for example, image information output from the photographing machine 22 and the control microcomputer 21) together with the cause of the event code estimated by the server 4. Output log data), the technician who possesses the mobile terminal 3A can confirm the status information of the elevator 2 together with the cause of the event code estimated by the server 4. Therefore, a technician who possesses the mobile terminal 3 </ b> A can confirm the cause of the event code estimated by the first server 5. As a result, this technician can perform maintenance work on the elevator 2 based on the cause of occurrence in addition to the maintenance work information 601.

  In the maintenance work support system 1, the storage unit 60 stores the check list 602 corresponding to the maintenance work information 601, and the portable terminal 3A outputs the check list 602 corresponding to the maintenance work information 601 together with the maintenance work information 601. The technician who possesses the portable terminal 3A can check the check list 602 corresponding to the maintenance work information 601. Therefore, this technician can perform maintenance work on the elevator 2 based on the check list 602 in addition to the maintenance work information 601. As a result, work leakage during maintenance work can be prevented.

  In the maintenance work support system 1 of the present embodiment, the technician who possesses the mobile terminal 3A can confirm the priority order to apply the maintenance work information 601 and the priority order to apply the checklist 602. Based on the maintenance work information 601 and the check list 602, the maintenance work of the elevator 2 can be performed.

  The maintenance work support system of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention. For example, the configuration of another embodiment can be added to the configuration of a certain embodiment, and a part of the configuration of a certain embodiment can be replaced with the configuration of another embodiment. Furthermore, a part of the configuration of an embodiment can be deleted.

  For example, although the storage unit 60 is provided in the server 4, it may be provided in the mobile terminal 3 or another terminal. That is, the mobile terminal 3 or another terminal may have the maintenance work information 601 and the like.

  The communication system R1 includes a telephone line, but may include the Internet instead of the telephone line. In this case, a part (Internet) of the communication systems R1, R2, and R3 may be common. For example, as shown in FIG. 3, the communication system R1 is a communication system that can communicate from the elevator 2 to the server 4 via the Internet, and a communication system that can communicate from the server 4 to the elevator 2 via the Internet. There may be. In FIG. 3, the elevator 2 is directly connected to the Internet. However, the elevator 2 may be connected to the Internet via a repeater such as a remote monitoring unit.

  In the maintenance work support system 1 of the above embodiment, the processing unit 50 outputs the address of the maintenance work information 601 and the address of the check list 602 to the mobile terminal 3A. Maintenance work information 601 and check list 602 corresponding to these addresses may be extracted, and the extracted maintenance work information 601 and check list 602 may be output to mobile terminal 3A.

  Further, the processing unit 50 may extract the maintenance work information 601 corresponding to the event code without using the database 600. Specifically, if the maintenance work information 601 corresponding to the event code is stored in the storage unit 60, the processing unit 50 does not use the database 600, but performs the maintenance work corresponding to the event code acquired from the control microcomputer 21. Information 601 and the like can be extracted. In this case, the storage unit 60 may not have the database 600.

  When the failure signal is output from the control microcomputer 21 (when there is a report), the first server 5 reads out the event code and outputs it to the mobile terminal 3A. The mobile terminal 3 may acquire an event code or the like by operating the mobile terminal 3 at the timing. In this case, the engineer operates the mobile terminal 3 and inputs the acquired event code or the like to the first server 5, so that the first server 5 extracts the maintenance work information 601 from the storage unit 60 and extracts the mobile terminal. 3, as a result, the portable terminal 3 can output the maintenance work information 601.

Even in this case, the mobile terminal 3A can output the maintenance work information 601 and the like.

  In the maintenance work support system 1 of the above embodiment, the maintenance work information 601 and the check list 602 are extracted after the estimation of the cause of occurrence of the event code (S03 in FIG. 2) (S04), but S03 and S04. May be performed simultaneously. Note that it is not necessary to estimate the cause of the event code.

  Furthermore, in the maintenance work support system 1 of the above embodiment, the first server 5 has acquired the status information of the elevator 2 together with the event code, but may acquire only the event code. Even in this case, the first server 5 can extract the maintenance work information 601 from the storage unit 60, and the portable terminal 3 can output the maintenance work information 601.

  In the maintenance work support system 1 of the above embodiment, the mobile terminal 3 outputs the check list 602 in addition to the maintenance work information 601, but may output only the maintenance work information 601.

  In addition to the processing of the maintenance work support system 1 of the above embodiment, the control microcomputer 21 determines whether the elevator 2 is abnormal, the first server 5 acquires the result of the abnormality determination by the control microcomputer 21, and the portable terminal You may output to 3A. Specifically, the control microcomputer 21 acquires the related memory value of the elevator 2, determines that there is no abnormality in the elevator 2 when this memory value is normal, and determines that there is an abnormality in the elevator 2 when this memory value is abnormal. Judge that there is. As this memory value, for example, there is a memory value in which the car speed and the car acceleration are stored. In this case, since the first server 5 acquires the determination result about the presence or absence of the abnormality of the elevator 2 from the control microcomputer 21 and the portable terminal 3 outputs the result of this determination, the technician who owns the portable terminal 3 Maintenance work of the elevator 2 can be performed based on the result of the determination of whether there is any abnormality.

  In the maintenance work support system 1, the elevator 2 is maintained by the technician using the portable terminal 3, but in addition, even if the operation state of the elevator 2 is remotely monitored by a terminal different from the portable terminal 3. Good. In this case, the communication system R1 may be a part of a communication network that remotely monitors the elevator 2.

  The output unit 30 of the mobile terminal 3 is a display unit such as a display, but may be a speaker or the like when outputting audio information such as an audio announcement. The mobile terminal 3 may have both a display and a speaker as the output unit 30.

  Although the server 4 includes the first server 5 and the second server 6, the first server 5 and the second server 6 may be separate or integrated.
