The diagnostic operation method of the elevator in the present embodiment is implemented under the control of the elevator control device 30. Moreover, the diagnostic driving program of the elevator in this embodiment is implemented by being installed in the elevator control device 30.

  The elevator 2 to be diagnosed includes a hoistway 3, a car 4 traveling up and down in the hoistway 3, and a counterweight 6 connected to the car 4 via a main rope 5. In the machine room 7 of the elevator 2, a hoisting machine 8 for rotationally driving the main rope 5 and a deflecting sheave 9 are installed. The hoisting machine 8 is provided with a brake Br to be diagnosed.

  Further, in the hoistway 3, the lower limit switch 3LS is installed near the lower floor BF, which is one end floor, and the uppermost floor limit switch 4LS is installed near the uppermost floor TF, which is the other end floor. It is done. The lower floor limit switch 3LS is a switch operated to decelerate the car 4 when the car 4 passes the lower floor BF. The top floor limit switch 4LS is a switch operated to decelerate the car 4 when the car 4 passes the top floor TF.

  Further, six hoistway limit switches 5LS, 6LS,..., 10LS are installed in the hoistway 3. The hoistway limit switches 5LS, 6LS,..., 10LS are switches for detecting the position of the car 4. Although the number of installed limit switches in the hoistway is six in the present embodiment, it is not limited to this, and may be increased or decreased according to the length of the hoistway 3 and the number of floors. Detection signals of the limit switches 3LS to 10LS are output to the car control device 40.

  The monitoring center 10 configuring the remote diagnosis system 1 transmits remote diagnosis schedule data for performing remote diagnosis of the elevator 2 to the remote monitoring device 20. The remote monitoring device 20 outputs a diagnosis command to the elevator control device 30 in accordance with the remote diagnosis schedule data received from the monitoring center 10. The elevator control device 30 performs diagnostic operation control of the elevator 2 when receiving the diagnosis command. The car control device 40 is installed in the car 4, and in the present embodiment, in particular, is used to control the door open / close diagnosis of the car 4.

  Next, referring to FIG. 2, functions of the respective devices constituting the remote diagnosis system 1 will be described.

  The monitoring center 10 includes a schedule registration unit 11 that registers a schedule for performing remote diagnosis, and a communication unit 12 that can communicate via a public line or other wireless or wired communication line. Then, schedule data for the elevator 2 to carry out the remote diagnosis operation, for example, when the remote diagnosis is performed every month, is transmitted to the remote monitoring device 20, starting designated date and start time data for each month.

  The remote monitoring device 20 includes a communication unit 21 that communicates with the monitoring center 10 and the elevator control device 30, and a schedule storage unit 22 that stores remote diagnosis schedule data. The remote monitoring device 20 transmits a diagnosis command to the elevator control device 30 via the communication unit 21 when the schedule date and time comes according to the remote diagnosis schedule data stored in the schedule storage unit 22.

  The elevator control device 30 includes a communication control unit 31, an operation control unit 32, a car position determination unit 33, a diagnosis progress management unit 34, a program execution unit 35, a diagnosis result storage unit 36, and a data editing unit 37. , And restart operation pattern determination unit 38.

  The communication control unit 31 is connected to the communication unit 21 of the remote monitoring device 20, and receives a diagnostic command from the remote monitoring device 20, and transmits the diagnosis result to the monitoring center 10 via the remote monitoring device 20. Further, the communication control unit 31 is connected to the car control device 40, and receives the detection result of the car control device 40.

  The operation control unit 32 controls the basic operation of the elevator 2, for example, the car 4 performs the up operation when the user presses the up button in the elevator hall, and the remote control used for the remote diagnosis operation A diagnostic program is stored.

  The car position determination unit 33 determines the current car position at the start of the remote diagnosis operation. In addition, it is determined whether the diagnosis operation can be performed more efficiently if traveling in the direction of the uppermost floor TF or the lowermost floor BF.

  The diagnosis progress management unit 34 stores the time when the elevator remote diagnosis is interrupted and how far the diagnostic block (remote diagnosis item) to be diagnosed has been implemented.

  The program execution unit 35 determines from which diagnostic block to be described later the remote diagnostic program is to be implemented.

  The diagnosis result storage unit 36 has an area for storing the diagnosis result of each diagnosis item in block units, and stores the diagnosis result when the diagnosis of one diagnosis block is completed.

  When the diagnosis of all the diagnosis blocks is completed, the data editing unit 37 edits the diagnosis result as diagnosis result data.

  In the resumption operation pattern determination unit 38, a combination of diagnosis blocks capable of resuming diagnosis in the shortest time when diagnosis is interrupted when a call is generated is preset as a diagnosis operation pattern. When the diagnosis restarts, the diagnosis is performed by selecting the optimal diagnosis operation pattern.

<Diagnostic operation method in the embodiment>
In the driving method in the embodiment, it is assumed that the diagnosis target item is divided into predetermined diagnosis blocks. The diagnostic operation is performed in units of diagnostic blocks, and the diagnostic result is stored in the diagnostic result storage unit 36 each time the diagnosis of one diagnostic block is completed. Then, when a car call occurs before the diagnosis of one diagnostic block is completed, the diagnosis of the diagnostic block is performed to the end, the diagnosis result is stored in the diagnosis result storage unit 36, and the diagnosis is temporarily suspended. And answer the car call.

<Block division>
When the elevator control device 30 receives the remote diagnosis start information from the remote monitoring device 20, the diagnostic operation performed by the remote diagnostic program provided in the operation control unit 32 is, as shown in FIG. Composed of blocks.

  The first block B1 uses the lowermost floor limit switch diagnosis processing B11, the rising rated speed diagnosis processing B12, the rising hoistway limit switch diagnosis processing B13, and the data storage processing B14 as processing items.

  The lower floor limit switch diagnosis process B11 is activated when the car 4 passes the lower floor BF to diagnose whether or not the lower floor limit switch 3LS for decelerating the car 4 operates normally.

  The rising rated speed diagnosis process B12 diagnoses whether the rated speed comes out at the rising of the car 4 and whether the shaking or vibration of the car 4 is normal when rising at the rated speed.

  The as-lifted hoistway limit switch diagnostic processing B13 diagnoses whether or not the limit switches 5LS to 10LS in the hoistway normally operate during the ascent operation of the car 4.

  When the diagnosis of the first block B4 is completed, the data storage process B12 stores the diagnosis result up to that point in the diagnosis result storage unit 36.

  The second block B2 sets top floor limit switch diagnosis processing B21, brake state diagnosis processing B22, and data storage processing B23 as processing items.

  The top floor limit switch diagnostic process B21 is activated when the car 4 goes over the top floor TF to diagnose whether the top floor limit switch 4LS for decelerating the car 4 operates normally.

  In the brake state diagnosis process B22, a predetermined torque is applied to the hoisting machine 8 while the car 4 is stopped without releasing the brake Br installed in the hoisting machine 8, and the holding power of the brake is normal. Conduct the confirmation of

  When the diagnosis of the second block B2 is completed, the data storage process B23 stores the diagnosis result up to that point in the diagnosis result storage unit 36.

  The third block B3 uses the descending rated speed diagnosis process B31, the descending hoistway limit switch diagnosis process B32, and the data storage process B33 as process items.

  The descending rated speed diagnosis processing B31 diagnoses whether or not the rated speed comes out when the car 4 descends, and whether the shaking or vibration of the car 4 is normal when the car falls at the rated speed. In addition, since shaking and diagnosis may differ between the raising and lowering of the hand basket, the rated speed diagnosis is performed once at the rising and falling times.

  When the car 4 is in the descent operation, the in-liftway limit switch diagnosis process B32 diagnoses whether or not the limit switches 10LS to 5LS in the hoistway operate normally.

  When the diagnosis of the third block B3 is completed, the data storage process B33 stores the diagnosis result up to that point in the diagnosis result storage unit 36.

  The fourth block B4 uses the car door diagnosis process B41, the low-level floor hall door diagnosis process B42, and the data storage process B43 as process items.

  The car door diagnostic process B41 is a process for diagnosing whether the opening and closing of the car door is normal, and is performed only once prior to the landing door diagnosis. In the car door diagnosis and the landing door diagnosis of each floor, it is confirmed that the data such as the opening and closing time of the door, the opening and closing speed, and the torque are normal.

  The lower floor landing door diagnostic processing B 42 stops at each floor of the lower floor, opens and closes the landing door, and diagnoses the operating state.

  When the diagnosis of the fourth block B4 is completed, the data storage process B43 stores the diagnosis result up to that point in the diagnosis result storage unit 36.

  The fifth block B5 uses the middle floor hall door diagnosis process B51 and the data storage process B52 as process items.

  The middle floor landing door diagnosis process B51 stops at each floor of the middle floor, opens and closes the landing door, and diagnoses the operating state.

  When the diagnosis of the fifth block B5 is completed, the data storage process B52 stores the diagnosis result up to that point in the diagnosis result storage unit 36.

  The sixth block B4 sets the upper floor hall door diagnosis process B61 and the data storage process B62 as process items.

  The high floor landing door diagnosis process B61 stops at each floor of the high floor, opens and closes the landing door, and diagnoses the operating state.

  When the diagnosis of the sixth block B6 is completed, the data storage process B62 stores the diagnosis result so far in the diagnosis result storage unit 36.

  FIG. 4 is a flowchart showing the procedure of the diagnostic operation method according to the embodiment.

  When the diagnostic cycle comes and a diagnostic command is input, the diagnostic program operates and the flowchart shown in FIG. 4 is started.

  According to the remote diagnosis operation schedule registered in the schedule registration unit 11 of the monitoring center 10, when the diagnosis command from the remote monitoring device 20 is transmitted to the elevator control device 30, the operation control unit 32 can execute the remote diagnosis operation It is determined whether the state is "n" (ST1). Here, "a state in which the remote diagnosis operation can be performed" means a state in which all the car calls of the elevator 2 are not present, and a state in which 10 seconds have elapsed since the diagnosis command is output. In the "operable state", the car light is turned off and the door open button light and the power failure light are turned on (automatic diagnosis operation start condition).

  When the automatic diagnosis operation start condition is satisfied, the operation control unit 32 determines that the diagnosis can be performed (ST1 YES). Next, the car position determination unit 33 confirms the current car position (ST2). Next, based on the current car position, it is determined which one of the top floor TF and the bottom floor BF is closer to travel (ST3).

  If the current car position is close to the lower floor BF, travel to the lower floor BF is performed. On the other hand, if the current car position is close to the top floor TF, the traveling to the top floor TF is performed.

  When the current position of the car 4 is close to the lower floor BF and the car 4 travels to the lower floor BF (ST4), as shown in FIG. 3, starting from the diagnosis and storage process of the first block, in order, Diagnosis / storage processing of the second block (ST6) → diagnosis / storage processing of the third block (ST7) → diagnosis / storage processing of the fourth block (ST8) → diagnosis / storage processing of the fifth block (ST9) → sixth Block diagnosis / storage processing (ST10) is executed. When the diagnosis of all the diagnostic blocks is completed, the diagnostic result is edited by the data editing unit 37 and collectively transmitted to the monitoring center 10 as diagnostic result data (ST11).

  On the other hand, when the car position is close to the top floor TF, the car travels to the top floor TF (ST12). Then, the second block diagnostic / storage processing (ST13) → the third block diagnostic / storage processing (ST14) → the first block diagnostic / storage processing (ST15) → the sixth block diagnostic / storage processing (ST16) → The diagnosis is executed in the order of the diagnosis and storage process of the fifth block (ST17) → the diagnosis and storage process of the fourth block (ST18). When the diagnosis of all the diagnostic blocks is completed, the diagnostic result is edited by the data editing unit 37 and transmitted to the monitoring center 10 as diagnostic result data (ST11).

<Limit switch diagnosis>
The limit switch diagnosis will be described with reference to FIG.

  The limit switch diagnosis is roughly divided into the bottom floor limit switch diagnosis, the top floor limit switch diagnosis, and the in-shaft limit switch diagnosis. It is desirable that diagnosis of the limit switch be performed twice, at the time of rising and lowering of the car 4.

  Specifically, as shown in FIG. 5, when the car 4 is lowered to the lower floor and the lower floor limit switch 3LS is operated, the contact state is turned on. When rising from this state, the contact state turns from on to off if normal. Similarly, it is possible to determine that the limit switches 5LS to 10LS in the hoistway and the uppermost floor limit switch 4LS are normal by shifting from the on state to the off state.

  In the limit switch diagnosis at the time of lowering, when the car 4 ascends to the uppermost floor and the uppermost floor limit switch 4LS is actuated, the contact state is shifted from the on state to the off state. When it descends from this state, the contact state turns from off to on if normal. Similarly, in the hoistway limit switches 10LS to 5LS and the lowermost floor limit switch 3LS as well, it can be determined as normal by shifting from the off state to the on state.

<Diagnostic operation pattern at restart (restart pattern)>
A diagnostic operation pattern at the time of resumption will be described with reference to FIG. 6 taking as an example a case where a diagnostic call is interrupted and a diagnostic operation is resumed after the diagnostic operation is interrupted in order to respond to the car call when a car call is generated at landing car diagnosis. . The patterns P1 to P4 shown below are stored in the resumption operation pattern determination unit 38, and are called to realize optimal resumption of diagnosis when an interruption event such as a car call occurs at the time of diagnosis. In FIG. 6, a hatched car 4 indicates a car position when a car call occurs during diagnosis. The white car 4 indicates the car 4 that moves when a car call occurs, and indicates the moving order by connecting arrows. The black-painted car 4 indicates the car position at the time of diagnosis resumption after the car call is completed.

  For example, although the fourth block B4 shown in FIG. 3 described above is a diagnostic block that sequentially executes a car door diagnosis and a lower floor landing door diagnosis, it is assumed that a car call is generated during the landing door diagnosis of the sixth floor . In this case, after the landing door diagnosis on the sixth floor is finished, the car call is not answered immediately, and the diagnosis of the fourth block B4 is completed, and the diagnosis result is stored in the diagnosis result storage unit 36, and then the car call is made. Respond to That is, it responds to the car call after the landing door diagnosis on the 7th and 6th floors is finished.

  Several restart patterns can be considered depending on the generation floor of the car call and the disused floor of the car 4 after the use of the user.

<Pattern P1>
It is assumed that a car call occurs on the 18th floor and the user gets off on the first floor (a landing floor). Since the landing door diagnosis from the first floor to the sixth floor is completed, the landing door diagnosis to the eighth floor is performed, and the diagnosis result of the diagnosis block of the fourth block B4 is stored in the diagnosis result storage unit 36. Thereafter, in response to the landing call, the car goes straight to the 18th floor, and when the user gets off on the first floor (a landing floor), the car 4 is made to go straight to the 9th floor and the diagnosis block of the fifth block B5 is implemented. After the diagnosis of the fifth block is completed, the diagnosis result is stored.

<Pattern P2>
It is assumed that a car call occurs on the 4th floor and the user gets off on the 10th floor. Also in this case, the landing door diagnosis up to the eighth floor is performed, and the diagnosis result of the diagnosis block of the fourth block B4 is stored in the diagnosis result storage unit 36. After that, in response to the hall call, the car 4 is made to go straight from the eighth floor to the fourth floor, and after carrying the user and operating to the 10th floor (riding floor), it descends from the 10th floor to the 8th floor, and the fifth block B5 Start the diagnostic block of

<Pattern P3>
It is assumed that a car call occurs on the 18th floor and the user gets off on the 25th floor (a abandoned floor).
It is not efficient to go down to the 8th floor and resume from the diagnosis block of the fifth block B5 after the diagnosis of the fourth block B4 is finished and the car call is answered. In this case, the upper floor landing door diagnosis of the sixth block B6 starting from the 21st floor is started. In the landing door diagnosis of the high floor, the floor door diagnosis is performed by sequentially rising from the 21st floor to the 35th floor.

<Pattern P4>
It is assumed that a car call occurs on the 18th floor and the user gets off on the 30th floor (a abandoned floor). In this case, the floor closest to the 30th floor, which is the abandoned floor, is the 35th floor to resume the diagnosis block. From the 35th floor, carry out a high floor entrance door diagnosis of the 6th block B6 to the 21st floor. After the high-rise floor landing door diagnosis of the sixth block B6 is finished, the mid-story floor landing door diagnosis of the fifth block B5 is subsequently performed.

  In the patterns P1 to P4, it was assumed that a car call occurred during the landing car diagnosis on the sixth floor, which is the end stage of the diagnosis of the fourth block B4. However, for example, if a car call occurs during landing door diagnosis on the second floor, after answering the car call after finishing landing door diagnosis up to the eighth floor, it takes a long time to respond. , Leading to the service degradation to the user. Therefore, in all patterns, it is determined whether diagnosis of one block is completed within a predetermined time (for example, 30 seconds to 1 minute), and if diagnosis can not be completed, car calls are prioritized and car calls are made. After completion, try again from the beginning of the block. As described above, by setting the diagnostic operation pattern in consideration of the influence on the user, it is possible to perform the efficient diagnostic operation while avoiding the service decrease to the user.

  As described above, according to the present embodiment, it is possible to reduce useless diagnostic operation of the elevator 2 as much as possible without impairing the convenience of the elevator user.
