  Therefore, the present invention provides a lifting device maintenance system that enables early response to minor troubles that can be solved by simple work.

  The lifting / lowering apparatus maintenance system of the present invention includes a lifting / lowering apparatus having an information output unit that outputs output information related to an event requiring maintenance work, a first terminal capable of communicating with the information output unit of the lifting / lowering apparatus, and the first A second terminal communicable with the terminal, wherein the first terminal is informed that a maintenance is requested when the difficulty of maintenance work obtained from the output information from the information output unit is low. While transmission to the second terminal is permitted, transmission of a notification requesting maintenance to the second terminal is prohibited when the maintenance work obtained from the output information from the information output unit is difficult. It is characterized by that.

  In the lifting device maintenance system, when the difficulty of maintenance work is low, a notification requesting maintenance is sent to the second terminal, so the person who owns the second terminal confirms this notification. Maintenance work with low difficulty can be performed. Therefore, for example, by having a person in the vicinity of a lifting device such as a manager of a building in which the lifting device is installed possess a second terminal, such a person has a low difficulty level of maintenance work ( Minor troubles that can be solved with simple operations) can be quickly dealt with.

  The lifting device maintenance system includes a storage unit in which a database is stored, output information from the information output unit includes an output event code, and the database requires maintenance work and the degree of difficulty of the maintenance work. A notification of requesting maintenance when the output event code from the information output unit and the first registration event code in the database match in the first terminal, including a low first registration event code May be permitted to be transmitted to the second terminal.

  According to such a configuration, the first registration event that includes the output event code and the database that includes the output event code and the notification that the maintenance request is required, and that requires maintenance work and low maintenance work difficulty.

Based on the information, it is judged whether or not the output of the output information is caused by a human event, and a notification to the effect that a maintenance is requested when it is caused by a human event is prohibited from being sent to the second terminal. May be.

  According to this configuration, based on information from at least one of the control microcomputer and the imaging device, it is determined whether the output of the information output unit is caused by an artificial event, and this output is caused by an artificial event. Since the notification of requesting maintenance to the second terminal is prohibited, the person who owns the second terminal against the output of the error code due to human mischief (human artifact) There is no need to respond.

  In the lifting device maintenance system, when the output information from the information output section is related to an event that requires no maintenance and can be restored in the first terminal, the second terminal is notified that maintenance is requested. Transmission to may be prohibited.

  According to such a configuration, when an event that does not require maintenance and can be restored occurs, a notification to the effect that maintenance is requested is prohibited from being transmitted to the second terminal. The person who owns the terminal does not need to respond.

  In another lifting device maintenance system according to the present invention, a lifting device having an information output unit that outputs a plurality of output information related to an event requiring maintenance work, and a first terminal capable of communicating with the information output unit of the lifting device And a second terminal communicable with the first terminal, and the first terminal requests maintenance when the difficulty level of maintenance work corresponding to all output information from the information output unit is low. While transmission of the notification to the effect to the second terminal is permitted, when the difficulty level of maintenance work corresponding to at least one output information from the information output unit is high, or at least from the information output unit When the difficulty level of maintenance work corresponding to one piece of output information is low, and the remaining output information is related to an event that requires no maintenance and can be recovered, a notification to the effect of requesting maintenance is sent to the second terminal. Transmission is inhibited, characterized in that.

  In the lifting device maintenance system, when the difficulty level of maintenance work corresponding to all output information is low, a notification requesting maintenance is sent to the second terminal. The maintenance work with a low difficulty level can be performed by confirming this notification. Therefore, for example, by having a person in the vicinity of a lifting device such as a manager of a building in which the lifting device is installed possess a second terminal, such a person has a low difficulty level of maintenance work ( Minor troubles that can be solved with simple work) can be quickly dealt with.

  The lifting device maintenance system includes a storage unit in which a database is stored, a plurality of output information from the information output unit includes an output event code, and the database requires maintenance work and is difficult to perform maintenance work.

FIG. 7 is a block diagram of a maintenance system for a lifting device according to a modification of the present invention.

  Hereinafter, a lifting system maintenance system (hereinafter simply referred to as a maintenance system) according to the present invention will be described. The maintenance system is a system for maintaining the lifting device when an abnormality or the like occurs in the lifting device. In general, maintenance of the lifting device is performed by a technician who possesses a technician portable terminal, but if the difficulty of maintenance work is low, a person other than the technician (advanced knowledge about the lifting device like a technician) is required. A person who does not have it (for example, a manager of a building where a lift value is installed) can also perform maintenance work. In this maintenance system, when the difficulty level of the maintenance work is low, a notification requesting maintenance is transmitted to the information terminal possessed by the administrator, and the administrator performs maintenance of the lifting device based on this notification. be able to.

  In addition, although there exist an elevator, an escalator, etc. in an raising / lowering apparatus, the maintenance system of an elevator is demonstrated below. Further, the maintenance of the elevator includes, for example, a maintenance response such as maintenance of a car door and a failure response such as repair of the car door.

  As shown in FIG. 1, the maintenance system includes an elevator 2, a server (first terminal) 3 that can communicate with the elevator 2, and an information terminal (second terminal) 4 that can communicate with the server 3. In the maintenance system 1 of the present embodiment, the server 3 includes a first server 31 and a second server (storage unit) 32 connected to the first server 31. A remote monitoring unit 5 connected between the elevator 2 and the server 3 is also provided.

  Although one elevator 2 is shown in FIG. 1, the maintenance system 1 of the present embodiment includes a plurality of elevators. Further, although one information terminal 4 is shown in FIG. 1, the maintenance system 1 of the present embodiment includes a plurality of information terminals.

  The elevator 2 includes an operation unit 20 that includes a car or the like that moves up and down the hoistway, and an information output unit 21 that outputs output information related to an event that requires maintenance work. The elevator 2 is connected to the server 3 via a communication system R1. For example, the communication system R1 can communicate with the server 3 via the remote monitoring unit 5 and the telephone line in order from the elevator 2, and conversely from the server 3 via the telephone line and the remote monitoring unit 5, the elevator 2 It is a communication system that can communicate with.

  The information output unit 21 outputs, for example, an event code as output information related to an event requiring maintenance work. That is, the output information from the information output unit 21 includes an output event code. In the maintenance system 1 of the present embodiment, the information output unit 21 includes a control microcomputer 22 that outputs an event code and log data as output information, a camera that captures the inside of the car and outputs a captured image in the car as output information, and the like. And a sound collector 24 such as a microphone that collects sound in the car and outputs sound information as output information. The information output unit 21 stores a history of output information (for example, a history of output event codes).

  The event code output from the control microcomputer 22 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, power failure, and the like. The event code includes information on the event code occurrence date and time.

  In the maintenance system 1 of this embodiment, when an event code is output from the control microcomputer 22, additional information such as load information, car speed information, control stage information, and operation mode information is output simultaneously. For this reason, the information output unit 21 stores a history of additional information together with a history of output event codes. The control stage information that is one of the additional information indicates, for example, that the elevator 2 is under inspection work.

  The log data output from the control microcomputer 22 is, for example, traveling characteristics of the car. Specifically, the log data indicates a speed command for the motor that moves the car, a motor speed feedback, a motor torque command, and other input / output information. When the abnormality indicated by the log data is caused by a power failure or human action, the log data relates to an event that requires no maintenance and can be recovered.

  The captured image output from the camera 23 is a captured image in the car as described above. Therefore, when it can be determined from the captured image that the car is unmanned, it can be determined that the output of the output information (for example, the output of the event code) is not caused by an artificial event. Further, when the photographed image includes an artificial action such as door opening or jumping that causes an abnormality, the photographed image relates to an event that requires no maintenance and can be restored.

  The sound information output from the sound collector 24 is the sound in the car as described above. Therefore, when it can be determined from the voice information that the car is unmanned, it can be determined that the output of the output information (for example, the output of the event code) is not caused by an artificial event.

  The server 3 includes the first server 31 and the second server 32 as described above. In the maintenance system 1 of the present embodiment, the server 3 can communicate with the information terminal 4 via the communication system R2. The communication system R2 is a communication system that can communicate with the information terminal 4 from the server 3 via the Internet and can communicate with the server 3 from the information terminal 4 via the Internet, for example. Specifically, the server 3 can communicate with the information output unit 21 of the elevator 2.

  The second server 31 stores a database 34. The second server 32 is connected to the first server 31 by, for example, a wired line, and is connected by, for example, P2P (Peer to Peer).

  The database 34 includes, for example, a first registered event code that requires maintenance work and has a low difficulty level for maintenance work, and a second registered event code related to an event that does not require maintenance work and can be restored. Specifically, the database 34 includes a combination of a first registered event code that requires maintenance work and has a low difficulty level for maintenance work, and a second registered event code related to a recoverable event that does not require maintenance work. Including. The database 34 of the present embodiment includes a table 1 (see FIG. 2) having information related to event codes with low difficulty of maintenance work and information related to treatment procedures set for each reference event code, the previous determination date and time, and A table 2 having information related to the previous notification date and time, a table 3 having information related to the combination of event codes (see FIG. 3), and a table 4 indicating information related to the notification destination corresponding to each elevator are included.

  In the maintenance system 1 of the present embodiment, the first registered event code is the reference event code in Table 1. The second registered event code is an event code when status information (for example, a captured image or log data) relates to an event that requires no maintenance work and can be restored. Note that the database 34 includes treatment procedures in addition to various tables.

  Specifically, as shown in FIG. 2, the table 1 includes data on a reference event code, reference additional information, image necessity, log data necessity, and treatment procedure (treatment procedure number). In the maintenance system 1 of the present embodiment, as described above, the reference event code of the table 1 is the first registered event code with a low difficulty level of maintenance work. It is assumed that the maintenance work for the elevator is necessary even when the difficulty level of the maintenance work is low or the difficulty level of the maintenance work is high.

  An event with a low level of difficulty in maintenance work (an event in which the level of difficulty in maintenance work is equal to or less than a predetermined level of difficulty) is, for example, clogged door sill, an obstacle in the door opening / closing path, or out of lighting. An event with a high degree of difficulty in maintenance work (an event in which the difficulty level of maintenance work exceeds a predetermined difficulty level) is an event other than the above-described event with a low degree of difficulty in maintenance work.

  When the image necessity item is set to 1, when determining whether or not the photographed image output from the information output unit 21 is related to an event that requires no maintenance and can be restored, and the information output unit 21 In at least one of the determinations as to whether the output is caused by an artificial event, it is necessary to check the captured image in the cage output from the camera 23, and 0 is entered in the item of necessity of image. In this case, it is not necessary to confirm the captured image in the car when making the above-described determination on the output of the information output unit 21.

  When 1 is included in the log data necessity item, when determining whether the log data output from the information output unit 21 relates to an event that requires no maintenance and can be restored, and the information output unit 21 Log data output from the control microcomputer 22 must be confirmed at least when determining whether or not the output is an event caused by an artificial factor, and 0 is entered in the log data necessity item If this is the case, the log data need not be confirmed when making the above-described determination regarding the output of the information output unit 21.

  As an event that requires both image confirmation and log data confirmation, there is, for example, car vibration. As an event that requires confirmation of an image, for example, there is the presence or absence of shaking. As an event that requires confirmation of log data, for example, there is an abnormality in the traveling speed of the car. As an event in which neither image confirmation nor log data confirmation is necessary, for example, there is a brake abnormality.

  In the maintenance system 1 of the present embodiment, the data indicating the procedure is set for each combination of the reference event code and the reference additional information. In the procedure, information related to the maintenance work of the elevator 2 is described. For example, an instruction about maintenance work for an event corresponding to a combination of the reference event code and the reference additional information is described. Specifically, in the procedure, an instruction “Please remove the deacyl waste” is described. The number of the treatment procedure indicates which part of the treatment procedure should be referred to.

  Table 2 includes elevator identification number (machine number), event code, additional information, previous determination date and time (date and time when the difficulty level of maintenance work was determined), previous notification date and time (last time) Of the notification date and time, that is, the date and time when the first server 31 sent the number of the procedure procedure to the information terminal 4 last time).

  Table 3 is data about the reference event code, the reference additional information, the combination event code, the combination additional information, the target period (target period of the combination event code), and whether to notify (notify / not notify). Respectively. The combination event code and combination additional information indicate a combination event code and additional information that can be generated in accordance with the combination of the reference event code and the reference additional information. The combination event code corresponding to each combination of the reference event code and the reference additional information may be one or plural.

  When 1 is entered in the target period item, the target period is the day of occurrence of the combination event code. When 7 is included in the item of the target period, the target period is within one week (seven days) from the occurrence of the combination event code. Whether or not there is a combination event code in the table 3 is determined by, for example, confirming whether or not the same event code as the combination event code is generated within the target period of the combination event code. Here, although the target period is a period in days, the target period may be a period in hours, minutes, and the like.

  As a combination of a reference event code (reference event code and reference additional information in the maintenance system 1 of this embodiment) and a combination event code (combination event code and combination additional information in the maintenance system 1 of this embodiment), for example, When the combination event code is an event code caused by a power reset of the elevator 2 (power off of the control panel of the elevator 2), these event codes are not notified regardless of the reference event code. Further, when the combination additional information indicates that the elevator 2 is under inspection work, these event codes are not notified regardless of the reference event code. Furthermore, when the standard event code is an event code caused by a power failure (power off of the building where the elevator 2 is installed) and the combined event code is an event code caused by a sudden stop, these event codes are notified. Not. The combination of the main reference event code and the combination event code is a combination of event codes that are related in terms of operation (caused by factors that directly affect each other).

  Table 4 includes an elevator identification number and notification destination information corresponding to the elevator identification number. The notification destination information is, for example, information on the information terminal 4 possessed by the manager of each elevator. In the maintenance system 1 of the present embodiment, communication from the first server 31 to the information terminal 4 is possible via the Internet, so the notification destination information in the table 4 is the IP address of the information terminal 4.

  The first server 31 has a CPU (Central Processing Unit) and the like. In the first server 31, the determination unit 33 is functionally formed by the CPU executing a desired program. The first server 31 is connected to the second server 32 by wire, for example, P2P (Peer to Peer).

  The determination unit 33 permits transmission to the information terminal 4 to request maintenance when the difficulty level of maintenance work obtained from the output information from the information output unit 21 is low. On the other hand, the determination unit 33 relates to an event where the maintenance work obtained from the output information from the information output unit 21 has a high difficulty level, or the output information from the information output unit requires no maintenance and can be recovered. In some cases, the notification to the information terminal 4 for requesting maintenance is prohibited. Hereinafter, the process of the determination part 33 is demonstrated in detail.

  The determination unit 33 acquires, for example, an event code and a history of additional information from the information output unit 21 at regular intervals or at an arbitrary timing, and determines the level of difficulty of maintenance work from the history of the event code and the like. To extract the target record. For example, the determination unit 33 extracts a record that is output from the control microcomputer 22 within a predetermined time and for which the determination of the difficulty level of the maintenance work has not yet been performed. Whether or not the record is output from the control microcomputer 22 within a predetermined time can be determined from the information on the occurrence date and time of the event code included in the event code described above. Whether the maintenance work difficulty level is determined in the record can be determined by referring to the previous determination date and time for the row corresponding to the event code and the additional information of the record in the table 2.

  The determination unit 33 compares the extracted target event code and the like with the table 1. Specifically, the determination unit 33 compares the target event code and the target additional information with the reference event code and the reference additional information in Table 1.

  When the target event code and the target additional information match the reference event code and the reference additional information in Table 1, the determination unit 33 uses Table 3 to determine whether or not the target event code and the target additional information are notification targets based on the combination of event codes. to decide. The determination unit 33 compares the target event code and the like with the table 1 because the reference event code and the reference additional information in Table 1 correspond to the event code and the additional information with a low difficulty level of the maintenance work. For the event code and the target additional information, the difficulty level of the maintenance work can be determined.

  The determination unit 33 determines that the target event code and the target additional information do not match the standard event code and the standard additional information in Table 1 (when the maintenance level of the target event code and the target additional information is high). If there is a target event code that has not been compared with Table 1 yet, the target event code is compared with Table 1. If there is no target event code that has not yet been compared with Table 1, the previous judgment date and time of Table 2 is set. Update and end the process.

  In the maintenance system 1 of the present embodiment, for example, the determination unit 33 compares the target event code and the target additional information with the reference event code and the reference additional information of the table 3 in order to make a determination using the table 3. Thus, it is determined whether or not there is a combination in Table 3. Further, when there is a combination in the table 3, the determination unit 33 reads the combination event code in the table 3, and extracts a record having the same event code as the combination event code from the event code and additional information history records. Then, it is determined whether or not the event code occurrence date is within the target period of the combination event code. Moreover, the determination part 33 determines whether there exists a combination notified to the table 3 by confirming the item about whether it is a notification object, when there exists such a record.

  The determination unit 33 compares the target event code with the table 1 if there is a target event code that has not been compared with the table 1 if there is a combination in the table 3 and there is no combination to be notified. If there is no target event code that has not yet been compared with Table 1, the previous determination date and time in Table 2 is updated, and the process ends.

  In the maintenance system 1 according to the present embodiment, when the determination unit 33 has no combination in the table 3 or when there is a combination in the table 3 and no combination to be notified, the table 1 includes the target event code and the target additional information. For records that match the reference event code and the reference additional information, it is determined whether there is status information related to an event that requires no maintenance and can be restored based on the status information, as necessary. Therefore, the table 1 includes a first registration event code (reference event code in the table 1) that requires maintenance work and has a low difficulty level, and a second registration event related to an event that does not require maintenance and can be restored. When a combination of the target event code and the combination of the event code including the second registered event code is matched In addition, the determination unit 33 determines that it is not a notification target.

  For example, the determination unit 33 refers to a record in the table 1 in which the reference event code and the reference additional information match the target event code and the target additional information, and whether or not to acquire the status information of this record (image acquisition) And whether or not log data needs to be acquired). If status information needs to be acquired, status information is acquired to determine whether there is status information related to an event that requires no maintenance and can be recovered. .

  Specifically, when acquiring a captured image from the camera 23, the determination unit 33 is not a notification target if the acquired captured image is dark and is status information regarding a power failure (an event that requires no maintenance and can be recovered). to decide. Note that the analysis of the captured image is performed by image recognition, for example. Further, when acquiring log data from the control microcomputer 22, the determination unit 33 determines that the acquired log data is not a notification target if it includes information about a power failure (an event that does not require maintenance and can be recovered).

  In the maintenance system 1 of the present embodiment, when the determination unit 33 determines that there is no situation information regarding an event that requires no maintenance and can be restored based on the situation information, whether the output of the situation information is caused by an artificial event. Judging.

  For example, the determination unit 33 refers to a record in which the reference event code and the reference additional information match the target event code and the target additional information among the records in Table 1, and determines whether or not to acquire the situation information (whether or not to acquire the image) If it is necessary to acquire the status information, the status information is acquired to determine whether the output of the status information is caused by an artificial event.

  Specifically, when acquiring a captured image from the camera 23, the determination unit 33 is not a notification target if the acquired captured image includes information on an artificial event (artificial abnormality) such as a jump. Judge. Further, when the determination unit 33 acquires log data from the control microcomputer 22, it is not a notification target if the acquired log data similarly includes information on an artificial event (human error) such as jumping. Judge.

  In the maintenance system 1 of the present embodiment, when the determination unit 33 does not require acquisition of the situation information and when it is determined to be a notification target based on the situation information, a predetermined time has elapsed from the previous notification date. The procedure is extracted when a predetermined time has elapsed. Specifically, the determination unit 33 confirms the previous notification date and time for the record including the event code and the additional information that matches the target event code and the target additional information from the table 2, and determines the current processing date and time from the previous notification date and time. When the period until the time exceeds a predetermined time, the number of the procedure point used for maintenance is extracted with reference to Table 1, and this target record (target event code and target additional information) is set as a transmission target.

  Thereafter, if there is a target event code that has not been compared with Table 1, the determination unit 33 compares this target event code with Table 1, and if there is no target event code that has not yet been compared with Table 1 ( If the target event code has been compared with all cases table 1), the previous determination date and time in table 2 is updated, and the process is terminated. For example, when the determination unit 33 extracts the treatment procedure number, the determination unit 33 obtains the treatment procedure number from the record in the table 1 in which the reference event code and the reference additional information match the target event code and the target additional information. Extract.

  Note that the determination unit 33, for a record including an event code and additional information that matches the target event code and target additional information, if the period from the previous notification date and time to the current processing date and time is equal to or shorter than a predetermined time, The previous determination date is updated and the process is terminated.

  When there is a transmission target, the determination unit 33 transmits a notification requesting maintenance (in the maintenance system 1 of the present embodiment, the number of procedure points extracted in addition to the notification requesting maintenance). The notification destination information to be used (for example, the IP address of the information terminal 4) is extracted. For example, the determination unit 33 refers to the table 4 when extracting the notification destination information, and determines the notification destination from the record in which the elevator identification number (hereinafter referred to as the target elevator identification number) in which the target event code is generated matches the elevator identification number. Extract information. In the maintenance system of the present embodiment, the determination unit 33 acquires the IP address of the information terminal 4 as notification destination information. In addition, the determination unit 33 updates the previous determination date and time and the previous notification date and time in the table 2 after transmitting the notification of requesting maintenance for the transmission target and the number of the treatment procedure, and other than the transmission target (not the transmission target) The previous determination date and time is updated for the target event code and target additional information), and the process ends.

  When there is no transmission target, the determination unit 33 updates the previous determination date and time in Table 2 and ends the process.

  The information terminal 4 is a portable terminal such as a PDA (Personal Digital Assistant) or a notebook personal computer. The information terminal 4 according to the present embodiment is possessed by a person who has less knowledge about the maintenance work of the elevator than a technician, such as an administrator who manages the elevator 2. In addition, the information terminal 4 may be possessed by a person who has knowledge about the maintenance work of the elevator, like the technician.

  In the maintenance system 1 of the present embodiment, the information terminal 4 has an output unit 40 as shown in FIG. The output unit 40 of the information terminal 4 outputs information received by the information terminal 4. The output unit 40 is a display when the output information is image information or text information, and is a speaker when the output information is audio information.

  Hereinafter, the flow of processing in the maintenance system 1 will be described with reference to the flowcharts of FIGS. Note that the processing flow shown in these flowcharts is repeated every predetermined time.

  When the determination unit 33 acquires an event code history (for example, event code and additional information history) from the information output unit 21 (S01), the determination unit 33 becomes a target for determining the difficulty level of the maintenance work from the history such as the event code. The target record is extracted (S02), and it is determined whether all the target records have been compared with reference to the previous determination date and time in Table 2 (S03). When all the target records are not compared (No in S03), the determination unit 33 compares the target event code and the target additional information with the reference event code and the reference additional information in Table 1 (S04).

  Note that when all the target records are compared (Yes in S03), the determination unit 33 proceeds to S18 in FIG. 6, and when there is a transmission target (Yes in S18), a notification destination (for example, based on Table 4) The IP address of the information terminal 4 is extracted (S19), the transmission target is transmitted to the information terminal 4 (S20), the table 2 is updated (S21), and the process is terminated. Further, when there is no transmission target (No in S18), the determination unit 33 updates the table 2 (S21) and ends the process.

  The determination unit 33 compares the target event code and the target additional information with the reference event code and the reference additional information in Table 1 (S04). If they match (Yes in S05), the determination unit 33 displays the target event code and the target additional information. The reference event code and the reference additional information in Table 3 are compared (S06).

  When the combination corresponding to the target event code and the target additional information is in the table 3 (Yes in S07) and this combination is a combination to be notified (Yes in S08), the determination unit 33 and the target event code and When there is no combination corresponding to the target additional information in the table 3 (No in S07), it is determined whether or not the situation information needs to be acquired with reference to the table 1 (S09).

  Note that the determination unit 33 compares the target event code and target additional information with the reference event code and reference additional information in Table 1 and if they do not match (No in S05), the determination unit 33 returns to S03 and is still in Table 1 If there is a target event code that is not compared with (No in S03), the target event code is compared with Table 1 (S04), and if there is no target event code that is not yet compared with Table 1 (S03) (Yes), it progresses to S18 of FIG. 6, and it transmits to the information terminal 4 as needed (S19-S20), updates the table 2, (S21), and complete | finishes a process.

  Even if the combination is in Table 3 (Yes in S07) and this combination is not the notified combination (No in S08), if there is a target event code that has not yet been compared with Table 1, the process returns to S03 ( No in S03), the target event code is compared with Table 1 (S04). If there is no target event code that has not been compared with Table 1 yet (Yes in S03), the process proceeds to S18 in FIG. Accordingly, transmission is performed to the information terminal 4 (S19 to S20), the table 2 is updated (S21), and the process is terminated.

  The determination unit 33 refers to a record in which the reference event code and the reference additional information match the target event code and the target additional information among the records in the table 1, and when the situation information needs to be acquired (Yes in S09 in FIG. 5). ), Status information is acquired from the information output unit 21 (S10), and this information is analyzed (S11). As a result of this analysis, the determination unit 33 has no situation information regarding an event requiring no maintenance and can be recovered (No in S12), and the output of the situation information is not caused by an artificial event (No in S13), or When acquisition of situation information is not necessary (No in S09), the target event code and target additional information are compared with the reference event code and reference additional information in Table 2 (S14).

  As a result of the comparison in S14, the determination unit 33 has a record including a matching event code and additional information (Yes in S15), and the period from the previous notification date to the current determination date exceeds a predetermined time (Yes in S16), or if there is no record including a matching event code and additional information as a result of the comparison in S14 (No in S15), refer to Table 1 and extract the number of the treatment procedure used for maintenance Then, this target record (target event code and target additional information) is set as a transmission target (S17).

  The determination unit 33 sets the target record as a transmission target (S17), or as a result of analysis of the status information (S11), when there is status information related to a maintenance-free and recoverable event (Yes in S12), or When it is determined that the output of the situation information is caused by an artificial event (Yes in S13), or when the period from the previous notification date to the current determination date is equal to or less than a predetermined time (No in S16), S03 If there is a target event code that has not been compared with Table 1 yet (No in S03), this target event code is compared with Table 1 (S04), and the target event code that has not yet been compared with Table 1 If there is no (Yes in S03), the process proceeds to S18.

  When there is a transmission target (Yes in S18), the determination unit 33 refers to the table 4, and obtains notification destination information (for example, the IP address of the information terminal 4) from a record in which the target elevator identification number and the elevator identification number match. Extract (S19), send a notification to the information terminal 4 for requesting maintenance and the number of procedure (S20), update the previous determination date and time and the previous notification date and time in Table 2 (S21), and end the process. . If there is no transmission target (No in S18), the determination unit 33 updates the previous determination date and time in Table 2 (S21) and ends the process.

  In the maintenance system 1 described above, when the difficulty level of maintenance work corresponding to the output event code (output information) is high, or when the output event code (output information) relates to an event that requires no maintenance and can be recovered, Is not permitted to be transmitted to the information terminal 4. When the difficulty level of the maintenance work is low for the output event code, the determination unit 33 sends a notification to the effect that the maintenance is requested to the information terminal 4, so that the manager who owns the information terminal 4 (the elevator compared to the technician) Who have little knowledge about maintenance work) can perform maintenance work with low difficulty. As a result, the manager who possesses the information terminal 4 can take an early response to a trouble with a low difficulty level of maintenance work (a minor trouble that can be solved with a simple work).

  That is, the maintenance system 1 has a high degree of knowledge about maintenance work such as a technician, and the difficulty level of maintenance work that does not need to be dealt with by a person who is likely to be away from the elevator 2 such as another site. Is notified to the information terminal 4 possessed by a manager or the like in the vicinity of the elevator 2 that the maintenance is requested, thereby enabling early response to the trouble.

  Further, in the maintenance system 1, the transmission of the notification requesting the maintenance to the information terminal 4 is included in the output event code and the database 34, and a combination event that requires maintenance work and has low difficulty in maintenance work. Since it is permitted when the code (first registered event code) matches, the output event code that causes the notification is uniquely determined as the first registered event code.

  Further, in the maintenance system 1, based on the output information from the control microcomputer 22 and the photographing machine 23, it is determined whether or not the output of the information output unit 21 is caused by an artificial event, and this output becomes an artificial event. Management of possessing the information terminal 4 for error code output due to human mischief or the like (artificial event) is prohibited because transmission to the information terminal 4 of requesting maintenance when it is caused is prohibited No longer need to be addressed.

  The maintenance system of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes 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, the determination unit 33 permits transmission to the information terminal 4 to request maintenance when the difficulty level of maintenance work obtained from the output information from the information output unit 21 is low, while from the information output unit 21 When the maintenance work obtained from the output information is difficult, or when the output information relates to an event that requires no maintenance and can be recovered, a notification to the effect that maintenance is requested is sent to the information terminal 4 Was prohibited. However, the present invention is not limited to this, and the determination unit 33 permits transmission of a notification requesting maintenance to the information terminal 4 when the difficulty level of maintenance work obtained from the output information from the information output unit 21 is low. On the other hand, when the difficulty level of the maintenance work obtained from the output information from the information output unit 21 is high, transmission of a notification requesting maintenance to the information terminal 4 may be prohibited. That is, it is not necessary to determine whether the output information relates to an event that requires no maintenance and can be recovered (S12). Further, it is not necessary to determine whether the output of the situation information is caused by an artificial event (S13). Furthermore, the determination unit 33 itself does not permit or prohibit transmission of a notification requesting maintenance to the information terminal 4, but a configuration other than the determination unit 33 permits or prohibits this transmission. May be. In this case, the database 34 only needs to include the first registered event code.

  Even in such a case, when the difficulty level of the maintenance work is low, a notification to request maintenance is transmitted to the information terminal 4, so that the administrator who owns the information terminal 4 (elevator maintenance compared to the technician) Those who lack knowledge about the work) can perform maintenance work with low difficulty. Therefore, such an administrator can take an early response to a trouble (a minor trouble that can be solved by a simple work) with a low degree of maintenance work difficulty.

  In the maintenance system 1 of the above embodiment, the reference event code of the table 1 is the first registered event code with a low difficulty level of the maintenance work, but the table 1 is the first registered event code and the difficulty level of the maintenance work. May contain high event codes. Even in this case, if the event code output from the control microcomputer 22 matches the first registered event code in Table 1, it is determined that the output event code has a low level of maintenance work difficulty. can do.

  Moreover, in the maintenance system 1 of the said embodiment, although the server 3 containing the 1st server 31 and the 2nd server 32 was used as a 1st terminal which can communicate with the information output part 21, a technician is a 1st terminal. It may be a technician portable terminal or a monitoring terminal. The monitoring terminal is a terminal for remotely monitoring the elevator 2 in the building as well as being installed in a building away from the elevator 2. Note that the server 3 may be composed of one server.

  The information output unit 21 includes the control microcomputer 22, the photographing machine 23, and the sound collector 24. However, the information output unit 21 only needs to include at least one of the control microcomputer and the photographing machine. Even in this case, based on information from at least one of the control microcomputer and the photographing machine, it is determined whether the output of the output information is caused by a human event, and the output of the output information is a human event. If it is caused by this, it is possible to prohibit transmission of a notification requesting maintenance to the information terminal 4. Therefore, when the occurrence of the situation information is caused by an artificial event, it is possible to prevent the manager from requesting a useless response.

  In the maintenance system 1 of the above embodiment, when the output of the output information is caused by an artificial event, no information is transmitted to the information terminal 4. The administrator may be alerted by transmitting the occurrence of the occurrence (for example, the occurrence of mischief).

  Further, in the maintenance system 1 of the above-described embodiment, the determination unit 33 determines whether or not the difficulty level of the maintenance work has been determined based on the previous determination date / time in the table 2 when extracting the target event code. However, it may be determined based on the previous notification date and time in Table 2. In addition, for example, when the determination unit 33 updates the table 2, a flag signal is set for the record of the event code for which the difficulty level of the maintenance work is determined, and the difficulty of the maintenance work is extracted when the target event code is extracted. It may be determined based on this flag signal whether or not the degree is determined.

  In the maintenance system 1 of the above-described embodiment, it is determined whether or not each output event code is a transmission target. In addition to this determination, whether or not all output event codes (all target event codes) are transmission targets. It may be determined whether or not. In this case, for example, when the difficulty level of maintenance work corresponding to at least one output event code (output information) is high, or the difficulty level of maintenance work corresponding to at least one output event code (output information) is low and When the remaining output event code (output information) relates to an event that does not require maintenance and can be recovered, the notification to the information terminal 4 that requests maintenance may be prohibited.

  Specifically, if the target record includes a target event code and target additional information with a high degree of difficulty of the corresponding maintenance work, a flag signal is set (for example, when No in S05 in FIG. 4) A flag signal is set), and the presence or absence of this flag is determined between S18 and S19 in FIG. 6, and when the flag is set (the target record includes an event code with high maintenance difficulty and target additional information) In the case where it is, the table in S21 is updated without performing transmission, and the process is terminated.

  If the table 1 includes a reference event code having a high degree of maintenance work difficulty and information on the difficulty level of the maintenance work associated with each reference event code, the maintenance work of the table 1 is again performed in S19. With reference to the difficulty level, it may be determined whether or not the target record includes a target event code having a high level of maintenance work difficulty.

  In this way, when the difficulty level of maintenance work is low for all output event codes, the determination unit 33 transmits a notification requesting maintenance to the information terminal 4, so that the administrator who owns the information terminal 4 (Those who have less knowledge about elevator maintenance work than technicians) can perform maintenance work with low difficulty. As a result, the manager who possesses the information terminal 4 can take an early response to a trouble with a low difficulty level of maintenance work (a minor trouble that can be solved with a simple work).

  The database 34 includes a combination of the first registered event code and the second registered event code, but may include only the first registered event code. Even in this case, when the output event code matches the first registered event code, the server 3 is permitted to send a notification requesting maintenance to the information terminal 4 and manage the information terminal 4. A person (who has less knowledge about elevator maintenance work than a technician) can perform maintenance work with a low difficulty level. Therefore, such an administrator can take an early response to a trouble (a minor trouble that can be solved by a simple work) with a low degree of maintenance work difficulty.

  In addition to the various tables, the database 34 includes treatment procedures, but the various tables and treatment procedures may be included in, for example, separate servers. Further, the server 3 stores, in the information terminal 4, a document describing a part of the maintenance work corresponding to the requested maintenance work among the plurality of maintenance works described in the treatment procedure instead of the number of the treatment procedure. You may send it.

  Although the maintenance system 1 of the above embodiment includes a plurality of elevators, the maintenance system 1 may include a single elevator. In this case, the table 2 and the table 4 may not have information on the elevator identification number. Moreover, although the maintenance system 1 includes a plurality of information terminals, the maintenance system 1 may include a single information terminal. In this case, the notification destination information included in the table 4 is one.

  The communication system R1 may include the Internet instead of the telephone line. For example, as shown in FIG. 7, the communication system R1 can communicate with the server 3 sequentially from the elevator 2 via the remote monitoring unit 5 and the Internet, and conversely from the server 3 to the Internet and the remote monitoring unit 5. It may be a communication system capable of communicating with the elevator 2 via In this case, the communication systems R1 and R2 are common in part (Internet). Moreover, although communication system R1 included the remote monitoring unit 5, it does not need to include this. In this case, the elevator 2 is connected to the first server 31 via the Internet.

  In the maintenance system 1 of the above embodiment, the server 3 acquires the output information from the information output unit 21, but instead, the information terminal 4 acquires the output information from the information output unit 21 by the operation of the administrator. The acquired output information may be transmitted to the server 3. In this case, the information terminal 4 may acquire output information from the information output unit 21 at regular intervals in addition to the operation timing of the technician (that is, any timing).

  The information terminal 4 is a terminal possessed by an administrator, but may be a terminal such as a mobile phone possessed by a person other than the administrator, for example, a user of the elevator 2.

  The maintenance system 1 of the above embodiment is targeted for an elevator as an elevating device, but may be targeted for an escalator. In this case, the maintenance system 1 includes a PLC unit (Programmable Logic Controller) as an information output unit instead of the control microcomputer 22, and an event code is output in the same manner as the control microcomputer 22. Further, the maintenance work with a low difficulty level is, for example, removal of foreign matter on the step, and the maintenance work with a high difficulty level is, for example, a step chain replacement.
