  The above-described remote diagnostic operation is temporarily interrupted when an elevator call is generated by the user during its operation. Then, when the response to the call is completed, the remote diagnosis operation is restarted from the beginning.

  As described above, if the remote diagnosis operation is suspended temporarily and re-executed from the beginning again, the processing efficiency deteriorates. Therefore, it is ideal to execute the remote diagnosis operation without interruption as much as possible. However, when the number of floors increases due to the increase in the number of floors of the building, the execution time of the remote diagnosis operation becomes longer, the probability that the user calls an elevator and the remote diagnosis operation is interrupted increases, and in some cases, the predetermined time There may also be cases where it can not be completed within.

  The present invention has been made in view of the above circumstances, and an elevator remote diagnosis operation method and elevator control apparatus for efficiently performing remote diagnosis operation on the elevator while minimizing the convenience of the elevator user. And a program for remote diagnostic operation of an elevator.

  According to the embodiment for achieving the above object, the elevator control device travels the elevator car at a low speed during execution of the remote diagnostic operation for remotely diagnosing the operating condition of the elevator equipment. A data acquisition process is performed to acquire moving distance data of a car at intervals. During the data acquisition process, when an elevator call occurs, the data acquisition process is interrupted, information on the space between the floors for which movement distance data has already been acquired is stored, and a response to the call is executed, When the response is completed, the data acquisition process resumes from the next floor between the stored floors. Then, based on the movement distance data for each floor acquired in the data acquisition process, it is remotely diagnosed whether or not the car is landed at the appropriate position on each floor, and remote diagnosis result information is generated.

There is. The winding machine 3 is provided with a pulse generator 31 that generates a pulse signal according to the rotation of the winding machine 3. Further, in the car 5, an in-car operation panel 51 is provided for the user to designate and operate the destination floor. Further, at the bottom of the car 5, a landing position detection sensor 52 for detecting landing detection plates (hereinafter referred to as "receiving plates") 72-1 to 72-10 in the hoistway 2 described later is set up.

  On each floor in building X, there is a landing for elevator E (1st landing 7-1 to 10 landing 7-10), and in landings 7-1 to 7-10, the user performs the landing call registration operation, respectively. There are landing control panels 71-1 to 71-10 for the operation. Further, landing plates 72-1 to 72-10 are installed at positions corresponding to the respective landings 7-1 to 7-10 in the hoistway 2. When the landing plates 72-1 to 72-10 are detected by the landing position detection sensor 52 of the car 5, respectively, the car 5 arrives at an appropriate position at each of the landings 7-1 to 7-10. It is installed to be on the floor.

  In the upper part of the hoistway 2, the elevator control device 30A connected to the hall control panel 71-1 to 71-10 and the winding machine 3 by a signal line and connected to the car 5 via the tail cord 8 is provided. is set up. The detailed configurations of the elevator control device 30A and the remote monitoring center device 10A will be described with reference to FIG.

  The remote monitoring center device 10A includes a first transmission / reception unit 101, a remote diagnosis schedule management unit 102, and a diagnosis result output unit 103. The first transmission / reception unit 101 transmits / receives information to / from the elevator control device 30A. The remote diagnosis schedule management unit 102 holds remote diagnosis schedule information for executing remote diagnosis of the elevator E to be monitored, and transmits the remote diagnosis schedule information from the first transmission / reception unit 101 to the elevator control device 30A. The diagnosis result output unit 103 receives the result of the remote diagnosis executed by the elevator control device 30A from the first transmission / reception unit 101 and outputs the result.

  The elevator control device 30A includes a clock unit 301, a second transmission / reception unit 302, a remote diagnosis operation command unit 303, a call registration unit 304, an operation control unit 305, a pulse data acquisition unit 306, and an implemented information storage unit. A pulse data storage unit 308, a landing position diagnosis unit 309, and a diagnosis result acquisition unit 310 are included.

  The clock unit 301 is an internal clock in the elevator control device 30A, and clocks current time information. The second transmission / reception unit 302 transmits / receives information to / from the remote monitoring center device 10A. Based on the remote diagnosis schedule information transmitted from the remote monitoring center device 10A and the current time information clocked by the clock unit 301, the remote diagnosis operation command unit 303 determines whether the execution start time of the remote diagnosis operation has arrived. To monitor Then, when it is determined that the execution start time of the remote diagnosis operation has come, the remote diagnosis operation command is output to the operation control unit 305. When the call registration unit 304 acquires the operation information of the landing consoles 71-1 to 71-10 by the user, the call registration unit 304 registers the landing call regarding the corresponding floor and direction. When the call registration unit 304 acquires the operation information on the in-car operation panel 51 by the user, the call registration unit 304 registers a car call whose destination floor is the corresponding floor.

  The operation control unit 305 includes a normal operation control unit 305a that executes normal operation of the elevator, and a remote diagnosis operation control unit 305b that executes remote diagnosis operation. The normal operation control unit 305a performs a normal operation by controlling equipment in the elevator such as the hoisting machine 3 so as to respond to the hall call or the car call registered in the call registration unit 304. When the remote diagnosis operation control unit 305b detects the remote diagnosis operation command output from the remote diagnosis operation command unit 303 during normal operation, the remote diagnosis operation control unit 305b starts remote diagnosis operation. Further, when the remote diagnosis operation control unit 305 b detects that the call registration unit 304 has registered the hall call or the car call during the remote diagnosis operation, the remote diagnosis operation is interrupted. After the interruption, when the response to the call is completed, the remote diagnosis operation is resumed from the next floor between the floors stored in the executed information storage unit 307 described later.

  The pulse data acquisition unit 306 detects each floor interval based on the detection information of the landing plates 72-1 to 72-10 by the landing position detection sensor 52 and the pulse signal generated from the pulse generator 31 of the winding machine 3. Pulse data indicated by the number of generated pulses of The executed information storage unit 307 stores, by the pulse data acquisition unit 306, information on the floor where acquisition of pulse data has already been performed.

  The pulse data storage unit 308 stores pulse data for each floor acquired by the pulse data acquisition unit 306. The landing position diagnosis unit 309 compares the total value for all floors of the latest pulse data stored in the pulse data storage unit 308 with the total value for all floors of the past pulse data. Then, it is diagnosed whether the landing position of each floor is appropriate. The diagnosis result acquisition unit 310 acquires the result diagnosed by the landing position diagnosis unit 309 and causes the second transmission / reception unit 302 to transmit the result to the remote monitoring center device 10A.

<Operation of Remote Diagnosis System for Elevator according to First Embodiment>
Next, the operation of the elevator remote diagnosis system 1A according to the present embodiment will be described with reference to the flowchart of FIG. In the present embodiment, the remote diagnosis schedule information of the elevator E held in the remote diagnosis schedule management unit 102 of the remote monitoring center device 10A is transmitted in advance from the first transmission / reception unit 101 to the elevator control device 30A. The transmitted remote diagnosis schedule information of the elevator E is received by the second transmission / reception unit 302 in the elevator control device 30A, and acquired by the remote diagnosis operation command unit 303.

  In the elevator E, during normal operation (S1), the hoisting machine responds to the hall call or car call registered in the call registration unit 304 by the normal operation control unit 305a of the operation control unit 305 of the elevator control device 30A. The equipment in the elevator E such as 3rd grade is controlled. In the meantime, the remote diagnosis operation command unit 303 determines whether the execution start time of the remote diagnosis operation has arrived based on the acquired remote diagnosis schedule information of the elevator E and the current time information clocked by the clock unit 301. It is monitored (S2). Then, when it is determined that the execution start time of the remote diagnosis operation has come ("YES" in S2), a remote diagnosis operation command is output to the operation control unit 305.

  In the operation control unit 305, when the remote diagnosis operation command is obtained, the remote diagnosis operation control unit 305b determines whether the call registration unit 304 is currently registered with a call (S3). As a result of the determination, when the call is registered, the normal operation is continued until the response to the call is completed ("YES" in S3).

  When the execution time of the remote diagnosis operation comes and the call is not registered, or when the response to the call ends ("NO" in S3), the remote diagnosis operation control unit 305b starts the remote diagnosis operation (S4). In remote diagnosis operation, ON / OFF operation diagnosis of the limit switch installed in the hoistway 2, operation diagnosis of the brake provided on the hoist, landing position diagnosis on each floor, diagnosis of the opening / closing operation of the door, etc. It is executed in a predetermined order. Among these, when it is time to execute landing position diagnosis on each floor ("YES" in S5), pulse data which is movement distance data of the car 5 for each floor is acquired for all floors. A process is implemented (S6).

  A specific process of acquiring pulse data for all floors will be described with reference to the flowchart of FIG. Here, it is assumed that pulse data is acquired in order from the floor between the first floor and the second floor, which is the lower floor, to the floor between the ninth floor and the tenth floor, which is the uppermost floor. First, from the state (S21) in which the car 5 is at the landing position of the first floor landing 7-1 and the landing plate 72-1 is detected by the landing position detection sensor 52 (S21), the rated speed during normal operation Also at low speed, upward movement is started (S22). When the movement of the car 5 is started, the pulse generator 31 of the hoisting machine 3 generates a pulse signal generated according to the rotation of the hoisting machine 3. The generated pulse signal is acquired by the pulse data acquisition unit 306.

  During movement, when the car 5 passes the landing position of the second floor landing 7-2, the landing plate detection sensor 52 detects the landing plate 72-2 ("YES" in S23). When the detection plate 72-2 is detected, the number of pulse signals generated from when the detection plate 72-1 is not detected to when the detection plate 72-2 is detected in the pulse data acquisition unit 306 Is counted. Since the number of pulse signals corresponds to the movement distance of the car 5, the number of pulse signals counted here is information indicating the distance between the first floor and the second floor. The counted pulse signal number is acquired by the pulse data acquisition unit 306 as pulse data between the first floor and the second floor (S24).

  When pulse data between the first floor and the second floor is acquired, information indicating that acquisition of pulse data between the floors has been performed is stored in the implemented information storage unit 307 (S25). Also, the acquired pulse data between the first floor and the second floor is stored in the pulse data storage unit 308 (S26). The above-described processing of steps S23 to S26 is performed until the landing plate detection sensor 52 detects the landing plate 72-10 on the tenth floor which is the uppermost floor and pulse data between the ninth floor and the tenth floor is acquired It is repeated ("NO" in S27).

  Returning to the flowchart of FIG. 3, the case where a call occurs in the elevator E during execution of the above-described pulse data acquisition process will be described. For example, during acquisition processing of pulse data, information indicating that acquisition processing of pulse data between the second floor and the third floor has already been performed when the car 5 reaches the third floor is in the implemented information storage unit 307. It is assumed that the call is registered in the call registration unit 304 in a state where the pulse data is stored and stored in the pulse data storage unit 308 ("YES" in S7).

  In this case, when a call is generated, the remote diagnosis operation under execution is interrupted by the remote diagnosis operation control unit 305b, and the normal operation control unit 305a executes a normal operation for responding to the call (S8). When the response to the call is completed ("YES" in S9), pulse data acquisition processing is resumed for the floors that have not been implemented before the interruption (S10).

  The specific process of acquisition of pulse data for unimplemented floors will be described with reference to the flowchart of FIG. When acquisition processing of pulse data is started for the unimplemented floors, first, between the floors for which acquisition of pulse data has been performed, which is stored in the implemented information storage unit 307 by the remote diagnosis operation control unit 305b. The latest information indicating is acquired (S31). Here, information indicating that acquisition of pulse data between the second floor and the third floor has been performed is acquired.

  When the information between the floors is acquired, the car 5 is moved to the lower floor between the next third floor and the fourth floor, that is, the third floor (S32). When the car 5 reaches the third floor and the landing plate detection sensor 52 detects the landing plate 72-3 ("YES" in S33), the movement is started upward at a low speed (S34).

  During movement, when landing plate detection sensor 52 detects landing plate 72-4 of the next floor (fourth floor) ("YES" in S35), pulse data acquisition unit 306 detects landing plate 72-3. The number of pulse signals generated between the time when the detection plate 72-4 is not detected and the detection of the attachment plate 72-4 is counted (S36). The counted number of pulse signals is acquired by the pulse data acquiring unit 306 as pulse data between the third floor and the fourth floor (S36).

  When pulse data between the third floor and the fourth floor is acquired, information indicating that acquisition of pulse data between the floors has been performed is stored in the implemented information storage unit 307 and acquired. The pulse data between the third and fourth floors are stored in the pulse data storage unit 308 (S37, S38). The above-described processes of steps S35 to S38 are performed until the landing plate detection sensor 52 detects the landing plate 72-10 on the tenth floor, which is the top floor, and pulse data between the ninth floor and the tenth floor is acquired It is repeated ("NO" in S39). If a call occurs again during that time, the process returns to step S8 in FIG. 3, the process proceeds in the order of “YES” in step S9 → S10, and the process shown in the flowchart of FIG. 5 is executed.

  When pulse data between all floors are stored in the pulse data storage unit 308 in a state where a call is not generated ("NO" in S7, "YES" in S11), storage in the landing position diagnosis unit 309 The pulse data between all the floors that have been added are added. Then, it is compared with pulse data for all the floors in the past. Here, if the difference between the pulse data for the first floor acquired this time and the pulse data for all the floors in the past is equal to or less than a predetermined value, the detection plates 72-1 to 72-10 are respectively accurate. In each floor, it is diagnosed that the car 5 can be landed at an appropriate position. In this case, the diagnosis result is "normal", and information on the landing position diagnosis result is generated. In addition, if the difference between the pulse data for all floors acquired this time and the pulse data for all floors in the past exceeds a predetermined value, the position of the car 5 on any floor is appropriate. It is diagnosed that it may not be possible to arrive at the hospital. In this case, the diagnosis result is "abnormal", and information on the landing position diagnosis result is generated (S12).

  Information on the generated landing position diagnosis result is acquired by the diagnosis result acquisition unit 310. Further, information on the results generated for diagnoses other than the landing position diagnosis is also acquired by the diagnosis result acquisition unit 310. When all remote diagnosis is completed ("YES" in S13), the normal operation control unit 305a returns to the normal operation. When the remote diagnosis operation ends, the information between the floors for which acquisition processing of pulse data has been performed, which is stored in the implemented information storage unit 307, is reset. Further, the diagnosis result of the remote diagnosis acquired by the diagnosis result acquisition unit 310 is transmitted from the second transmission / reception unit 302 to the remote monitoring center device 10A. In the remote monitoring center device 10A, the diagnosis result of the remote diagnosis transmitted from the elevator control device 30A is received from the first transmission / reception unit 101, and output from the diagnosis result output unit 103 by display or voice.

  According to the first embodiment described above, for the landing position diagnostic process of the remote diagnostic operation of the elevator, the process to acquire pulse data of the hoist generated during the movement of the car between the floors is called the generated call. If acquisition processing is interrupted for a response, remote diagnosis operation can be efficiently performed by resuming the processing to the floor where pulse data can not be acquired after the response.

Second Embodiment
<Configuration of Remote Diagnosis System for Elevator according to Second Embodiment>
The configuration of the elevator remote diagnosis system according to the second embodiment of the present invention will be described with reference to FIG. The elevator remote diagnosis system 1B according to the present embodiment has the same function as the configuration of the remote diagnosis system 1A described in the first embodiment, except that the elevator control device 30B includes the restart position determination unit 311. The detailed description of the part having the is omitted.

  In the present embodiment, the restart position determination unit 311 of the elevator control device 30B responds to the occurrence of a call after generation of a call during processing for acquiring pulse data for each floor and processing is interrupted for the landing position diagnosis. Based on the information on the floor between which the data acquisition processing has been performed and the current position information of the car 5, the restart position of the pulse data acquisition processing is determined. The remote diagnosis operation control unit 305b resumes the pulse data acquisition process from the position determined by the restart position determination unit 311 when the response to the call is completed after the interruption of the remote diagnosis operation.

<Operation of Remote Diagnosis System for Elevator according to Second Embodiment>
Next, the operation of the elevator remote diagnosis system 1B according to the present embodiment will be described with reference to the flowchart of FIG. In FIG. 7, the processes performed in steps S1 to S9 are the same as the processes described in the first embodiment, and thus detailed description will be omitted.

  In step S9, when the process for responding to the call executed while interrupting the remote diagnosis operation is completed ("YES" in S9), the restart position determination unit 311 determines the restart position of the pulse data acquisition process (S14) .

  The determination process of the restart position of the pulse data acquisition process will be described with reference to the flowchart of FIG. First, the information on the floor between which the pulse data acquisition process has been performed and the current position information of the current car 5 (information on the position where the call was abandoned after the call response) stored in the executed information storage unit 307 is acquired. (S41). Here, information on “the space between the second floor and the third floor” is acquired as the space between which the pulse data acquisition processing has been performed, and “the fifth floor” is acquired as the current position information of the car 5. Do. Since the pulse data acquisition process is performed by moving the car 5 upward from the first floor, if the interval between the implemented floors is “the floor between the second floor and the third floor”, the interval between the unimplemented floors is not performed. Is between the 3rd and 4th floors, between the 4th and 5th floors ... between the 9th and 10th floors.

  Next, it is determined whether the acquired current position of the car 5 corresponds to the lower floor between the unimplemented floors (S42). Here, the current position "fifth floor" of the car 5 corresponds to the lower floor "fifth floor" between "the fifth floor and the sixth floor" which is one of the floors for which acquisition processing of pulse data has not been performed. Then, it is determined ("YES" in S42), and the current position "5th floor" of the car 5 is determined as the resumption position of the pulse data acquisition process (S43). In addition, if it is determined that the current position of the car 5 does not correspond to the lower floor between the floors for which the acquisition process of pulse data has not been performed (“NO” in S42), the lower floor between the lowermost unimplemented floors ( Here, "3rd floor" is determined as the restart position (S44).

  Referring back to FIG. 7, the car 5 is moved upward at a low speed from the determined restart position, and the remote diagnosis operation control unit 305b resumes the pulse data acquisition process (S15). If another call is generated before the car 5 reaches the 10th floor which is the top floor after being resumed ("NO" in S16, "YES" in S7), the processing in steps S8, S9, S14, and S15 is repeated. Be

  When the car 5 reaches the top floor ("YES" in S16), it is determined whether there is a floor space for which the pulse data acquisition process has not been performed (S17). As in the example above, when pulse data between the 2nd and 3rd floors are acquired and you answer the call, and then restart the pulse data acquisition process from the 5th floor, “3rd and 4th floors The acquisition process of the pulse data of "the floor between floor" and "the floor between the fourth floor and the fifth floor" is not performed yet ("YES" in S17). Therefore, the process returns to step S14, the restart position is determined to be "3rd floor" according to the flowchart of FIG. 8 (S14), and the pulse data acquisition process is restarted from the determined position (S15).

  Then, when the car 5 has reached the top floor ("YES" in S16), if there is no space between the floors for which the pulse data acquisition process has not been performed ("NO" in S17), the process proceeds to step S12. As in the one embodiment, information on the landing position diagnosis result is generated (S12).

  Information on the generated landing position diagnosis result is acquired by the diagnosis result acquisition unit 310. Further, information on the results generated for diagnoses other than the landing position diagnosis is also acquired by the diagnosis result acquisition unit 310. When all remote diagnosis is completed ("YES" in S13), the normal operation control unit 305a returns to the normal operation.

  According to the above-described second embodiment, for the landing position diagnostic process of the remote diagnostic operation of the elevator, the process for acquiring pulse data of the hoist generated during the movement of the car between the floors is called the generated call. If the acquisition process is interrupted for a response, the remote diagnosis operation can be performed more efficiently by resuming the pulse data acquisition process from the position where the car was abandoned after the response.

If it is determined that it occurs, the pulse data between the corresponding floors is corrected to correct to the proper landing position. The correction data storage unit 313 stores the pulse data corrected by the pulse data correction unit 312 as pulse correction data. When the remote diagnosis operation control unit 305b of the operation control unit 305 executes landing position diagnosis in remote diagnosis, pulse data between floors in which the pulse correction data stored in the correction data storage unit 313 is equal to or more than a predetermined value To get And about the floor where pulse correction data more than a predetermined value was not stored at the time of normal operation, about the floor where pulse correction data more than a predetermined value was stored at the time of normal operation using pulse data acquired at the time of normal operation. The terminal diagnosis processing is executed using the pulse data acquired by the remote diagnosis operation control unit 305b.

<Operation of Remote Diagnosis System for Elevator according to Fourth Embodiment>
Next, the operation of the elevator remote diagnosis system 1D according to the present embodiment will be described with reference to the flowchart of FIG. In the present embodiment, even during normal operation (S1), based on the information of the landing plates 72-1 to 72-10 of each floor detected by the landing position detection sensor 52 when the car 5 moves up and down. The pulse data for each floor is acquired by the pulse data acquisition unit 306. Then, based on the acquired pulse data for each floor, the normal operation control unit 305a performs landing position correction processing for causing the car 5 to be landed at an appropriate position on each floor. . In the landing position correction process, when the pulse data between the floors acquired during the normal operation is different from the reference value of the pulse data between the floors held in advance, the pulse data correction unit 312 performs the reference value of the pulse data. Is corrected. Since the reference value of the pulse data is used to control the landing position of the car 5, the deviation is eliminated and the car 5 is landed at an appropriate position by correcting it with the actual measurement value acquired during the normal operation. It can be done. When the reference value of pulse data is corrected, the corresponding pulse correction data is stored in the correction data storage unit 313. Because the car 5 is running at rated speed during normal operation, the pulse data acquisition accuracy is slightly lower than during low-speed travel during remote diagnosis operation, but it should be effectively used for landing position correction processing. it can.

  Assuming that the remote diagnosis operation execution start time arrives ("YES" in S2) on the assumption that the operation is performed in this way during normal operation ("NO" in S3), the remote diagnosis Driving is started (S4).

  When the remote diagnosis operation is started, the remote diagnosis operation control unit 305b determines whether pulse correction data is stored in the correction data storage unit 313 (S51). If it is determined that the pulse correction data is stored ("YES" in S51), it is further determined whether or not there is data corrected by a predetermined value or more in the stored pulse correction data. (S52). When there is data corrected by a predetermined value or more, it is determined by the landing diagnosis processing that it is necessary to acquire pulse data between corresponding floors.

  After it is determined that there is a floor area where pulse data acquisition is required ("YES" in S52), when the execution timing of landing position diagnosis comes ("YES" in S5), it is determined necessary in step S52 A process of acquiring pulse data at low speed traveling is performed on the floor as a target (S53).

  A call is generated during pulse data acquisition processing ("YES" in S7), the processing is interrupted, and after the response to the call is performed (S8), when the response to the call is completed (S9) “YES”), the restart position determination unit 311 determines the restart position of the pulse data acquisition process (S14). At this time, the restart position is determined based on the floor determined to be necessary in step S52. The processes executed until the landing position diagnosis result is generated thereafter are the same as the processes described in the second embodiment, and thus detailed description will be omitted.

  When the target floor pulse data acquisition process is completed, the landing position diagnosis unit 309 acquires pulse data acquired during the normal operation for the floor during which the pulse correction data of the predetermined value or more is not stored during the normal operation. Is used, and pulse data acquired by the remote diagnosis operation control unit 305b is used between floors in which pulse correction data of a predetermined value or more is stored during normal operation, and pulse data for all floors is calculated. Be done. Then, information on the landing diagnosis result is generated from the difference between the calculated pulse data of all the floors and the pulse data of all the past floors (S12).

  According to the fourth embodiment described above, pulse data is acquired only for the floors that may have an abnormality, using the result information of the pulse data correction process being performed during normal operation. Since the landing position diagnosis is performed, the remote diagnosis operation can be performed more efficiently.
