Description

  Embodiments of the present invention relate to an elevator remote diagnosis operation method, an elevator controller, and an elevator remote diagnosis operation program.

  The conventional remote diagnosis for elevators is provided in the elevator control device by transmitting a remote automatic diagnostic operation signal from the monitoring center to the property on which the remote maintenance terminal (remote monitoring device) is installed via the communication network. The automatic diagnosis operation of the elevator is performed by starting the diagnostic program. When the diagnostic operation is finished, the diagnostic result data is transmitted to the monitoring center.

  Conventionally, when performing elevator remote diagnosis operation and transmitting diagnosis result data to a monitoring center, all diagnosis result data are transmitted after all the remote diagnosis operations are completed.

JP-A-6-48665 Unexamined-Japanese-Patent No. 5-270760

  However, the conventional transmission method of collectively transmitting all diagnostic result data after all remote diagnostic operations are completed has the following problems. That is, a part of the diagnostic items can not be completed for some reason, and the retry setting time of the corresponding diagnostic item, the number of times of setting the retries, etc. may be exceeded, resulting in failure of the remote diagnostic operation. Also, remote diagnosis may be interrupted frequently due to the operation of the elevator user during diagnostic operation, resulting in failure. As described above, when the remote diagnosis operation is stopped, the entire diagnosis data can not be transmitted, and therefore, the remote diagnosis result may not be obtained at all. In addition, since batch transmission is performed, if the data volume to be transmitted at one time is too large, transmission may not be possible during communication due to a communication failure. Furthermore, if a communication failure occurs in the middle of communication, communication occurs a plurality of times, and the communication cost also increases.

  In view of the above circumstances, the embodiment of the present invention makes it possible to reliably acquire the diagnosis result of the remote diagnosis operation by suppressing the occurrence of the above-mentioned failure, and quickly and efficiently collecting the diagnosis result data at the monitoring center It is an object of the present invention to provide an elevator remote diagnosis operation method, an elevator control device, and an elevator remote diagnosis operation program that can be performed.

  In an aspect for achieving the above object, an elevator control device having received a diagnostic command output on a monitoring center or a remote monitoring device provided on the elevator side at a preset date and time is installed in a hoistway A remote diagnosis operation method of an elevator for traveling a car of an elevator and performing a remote diagnosis operation on an article constituting the elevator, wherein the article to be diagnosed is divided into predetermined diagnosis block units, and each diagnosis block Is composed of one or more diagnostic items, and the diagnostic operation is performed in units of diagnostic blocks, and the diagnostic result is stored in the storage unit each time the diagnosis of one diagnostic item constituting the diagnostic block is completed, and one diagnostic is performed. When the diagnosis of the block is completed, the diagnosis result stored in the storage unit is edited and transmitted to the monitoring center as diagnosis result data. That is a remote diagnostic method for operating the elevator.

  In addition, the present invention is an elevator control device that executes the above-described remote diagnosis operation method.

  Furthermore, it is a remote diagnosis operation program of an elevator for making an elevator control device perform the remote diagnosis operation method mentioned above.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, an elevator to which the diagnostic operation method in the embodiment is applied will be described with reference to FIG.

  As shown in FIG. 1, the remote diagnosis system 1 for performing remote diagnosis includes a monitoring center 10, a remote monitoring device 20, an elevator control device 30, and a car control device 40. 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.

  The monitoring center 10 constituting the remote diagnosis system 1 transmits remote diagnosis schedule data for performing remote diagnosis of the elevator to the remote monitoring device 20. The remote monitoring device 20 outputs a diagnosis command to the elevator control device 30 when the diagnosis operation start time set in advance is reached according to 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 for detecting the operation of each limit switch 3LS to 10LS and controlling the 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 with a public line or other wireless or wired communication. Then, schedule data for the elevator 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 of 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 according to the remote diagnosis schedule data stored in the schedule storage unit 22 when the schedule date and time (diagnosis operation start time) comes.

  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. Is equipped.

  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 executes control of basic operation of the elevator, for example, when the user presses the up button in the elevator hall, the car performs an up operation, and a remote diagnosis program used for remote diagnosis operation Is stored.

  The car position determination unit 33 determines the current car position at the start of the remote diagnosis operation, and determines in the direction of the top floor TF or the bottom floor BF whether the diagnostic operation can be efficiently performed.

  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.

  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 constituted of, for example, the following three diagnostic blocks: . Here, the diagnostic block refers to one group when performing remote diagnosis.

  For example, the first diagnostic block causes the car 4 of the elevator 2 to travel at a normal traveling speed, and the detection unit 42 of the car control device 40 performs switches necessary for the elevator 2 to travel safely when traveling, for example End floor limit switch diagnosis to confirm that the position of the switch is not shifted when the car 4 is traveling by turning on and off the limit switch installed near the end floor to detect the speed of the car 4 and the hoistway 2 In the hoistway limit switch diagnosis which is performed at the predetermined position of the upper case to check the operation of the hoistway limit switches 5LS to 10LS.

  The second diagnostic block does not release the brake Br provided on the hoisting machine 8 at the position of the top floor TF of the car 4 in the hoistway 3 and allows torque to be applied to the hoisting machine 8 with the car 4 stopped. It is a block constituted by "brake diagnosis" which applies and confirms and confirms that the holding power of a brake is normal.

  The third diagnosis block is a block constituted by “door open / close diagnosis” in which the car 4 is moved to each floor and the door control unit 41 of the car control device 40 opens and closes the door and confirms the open / closed state when stopped. . In the "door open / close diagnosis", it is confirmed that data such as the open / close time of the door, the open / close speed, and the torque are normal.

  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 one diagnosis item is completed.

  When the diagnosis of one diagnostic block is completed, the data editing unit 37 reads the diagnostic result stored in the diagnostic result storage unit 36 and edits the diagnostic result data in block units.

  The car control device 40 includes a door control unit 41 and a detection unit 42. The door control unit 41 executes control of a car door and control of a landing door of each floor. While traveling in the hoistway, the detection unit 42 checks on / off of the lowermost floor limit switch 3LS, the uppermost floor limit switch 4LS, and each intra-highpass limit switch 5LS, 6LS,. Detects whether the limit switch operates properly. Then, the detection result of the car door inspection by the door control unit 41 and the diagnosis result of the limit switch by the detection unit 42 are transmitted to the elevator control unit 30 by communication between the elevator control unit 30 and the car control unit 40 It is stored in the diagnostic result storage unit 36 provided in the device 30. The result of the remote diagnosis operation is transmitted from the communication control unit 31 to the monitoring center 10 via the communication unit 21 of the remote monitoring apparatus 20 and the communication unit 12 of the monitoring center 10 as diagnosis result data.

<Diagnostic operation method>
Below, the procedure of the remote diagnostic driving | operation in this embodiment is demonstrated.

  As shown in FIG. 3A, the remote diagnosis implementation content of the present embodiment is composed of a first diagnosis block, a second diagnosis block,..., And an Nth diagnosis block. In the following description and drawings, "diagnosis block" may be simply described as "block".

  Each block is composed of n diagnostic items (diagnostic item 1, diagnostic item 2,..., Diagnostic item n.) Further, as shown in FIG. The result is stored when the diagnostic item in each block is finished, and the diagnostic result data is edited by the data editor 37 when the diagnosis for one block is finished, as shown in FIG. And sent to the monitoring center 10.

  FIG. 4 is a flowchart showing the procedure of the diagnosis process.

  When the remote diagnosis operation command from the remote monitoring device 20 is transmitted to the elevator control device 30 in accordance with the remote diagnosis operation schedule registered in the schedule registration unit 11 of the monitoring center 10, the operation control unit 32 establishes a diagnosis condition. It is determined whether or not (ST1). Here, the "state in which the diagnosis condition is established" refers to the "executable state" of the remote diagnosis operation. For example, it is in a state where there are no car calls of the elevator 2 and in which 10 seconds have elapsed since the diagnostic command was 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, it is determined that the diagnosis can be performed (ST1 YES).

  Next, the diagnosis block N = 1 and the diagnosis item n = 1 are set (ST2), and the diagnosis for the diagnosis item 1 of the first block is started (ST3). If the diagnosis of the diagnosis item 1 ends within a predetermined time, the diagnosis result is stored in the diagnosis result storage unit 36 (ST4 YES, ST7).

  If the diagnosis item 1 does not end within a predetermined time, that is, if a plurality of try times end (retry time over) (ST 5 YES), the diagnosis result is stored in the diagnosis result storage unit 36. In this case, the result of diagnosis failure is stored. Alternatively, the storage field of the diagnostic result of the diagnostic item is left blank and nothing is stored.

  In the case where the number of retries is over for the diagnosis item 1 (ST6 YES), the diagnosis result of diagnosis failure is similarly stored in the diagnosis result storage unit 36 (ST7). Or, the diagnostic item is left blank and nothing is stored.

  When the diagnosis of the diagnosis item 1 ends, the diagnosis of the next diagnosis item 2 is performed (ST9).

  When the diagnosis of all the diagnostic items n in the first block is completed, the data editing unit 37 reads out and edits the diagnostic result of each diagnostic item stored in the diagnostic result storage unit 36 (ST10). It transmits to the monitoring center 10 via the remote diagnosis device 20 as diagnosis result data (ST11). In addition, while the diagnosis of the first block is finished, the diagnosis result is read out and edited, and the diagnosis result data is transmitted to the monitoring center 10 in parallel while the diagnosis of the next second block is performed. carry out.

When there is a diagnostic block (ST12 YES), N = N + 1 is set to start diagnosis of the next diagnostic block, and diagnosis of diagnostic item 1 of the second diagnostic block is started (ST13).
When all the diagnosis of the diagnosis block is finished (ST12 NO), the diagnosis process is finished.

  According to the present embodiment, the remote diagnosis operation is composed of a plurality of blocks, and one block is composed of a plurality of diagnostic items. A transmission point is provided for each block unit, and the diagnostic result is transmitted to the monitoring center 10 when the diagnosis for one block diagnostic item is all completed.

  Thus, the diagnosis result of the remote diagnosis can be transmitted to the monitoring center 10 block by block. That is, for some reason, diagnosis can not be performed on the diagnosis item in the middle of the remote diagnosis operation, and the corresponding diagnosis item fails to be diagnosed. As a result, the remote diagnosis operation is canceled or the remote diagnosis is performed by the elevator user's operation. Even when the remote diagnosis operation is stopped due to frequent interruption, etc., data until the interruption is transmitted. Thus, even when the remote diagnosis operation is performed again, the diagnosis can be resumed from the portion where the diagnosis could not be performed, and efficient remote diagnosis operation can be provided. In addition, as for the diagnosis result, there is also a situation where the diagnosis results in failure if the diagnosis times out in some circumstances or the number of retries exceeds, and the diagnosis results can not be acquired.

  In addition, when transmitting diagnostic results in block units, diagnostic items for which a diagnostic result could not be obtained for some reason may be diagnosed more efficiently by making it a diagnosis failure or transmitting without including it in the transmission content. It is possible to transmit the result to the monitoring center 10.

<Example>
Next, the present invention will be described as a more specific example with reference to FIG.

  In the above description, for example, three diagnosis blocks of “limit switch diagnosis in hoistway”, “brake diagnosis”, and “door open / close diagnosis” are assumed as diagnosis blocks. In this embodiment, the diagnostic operation of the elevator 2 is performed by a first block that diagnoses a shaft limit switch (including a lower floor limit switch) when the car moves up, and a second block that performs a brake diagnosis, The car is divided into four blocks, the third block that diagnoses the hoistway limit switch (including the top floor limit switch) when the car goes down, and the fourth block that diagnoses the landing door on each floor. .

  Each block is composed of a diagnostic item that makes a diagnosis in accordance with the respective block. For example, the first block includes diagnostic items such as "operation and position confirmation of lower floor limit switch" and "operation and position confirmation of each floor limit switch".

  When the diagnostic command is output from the remote monitoring device 20, the remote diagnostic operation is started (ST21). First, the car 4 is pulled back to the lower floor BF (ST22), and diagnosis of the diagnosis item 1 of the first block is started. As this diagnostic content, the load is checked after the car 4 has stopped at the lower floor BF. This is a check whether there is a user in the car 4 (D1). If it is confirmed that the interior of the car 4 is unmanned, diagnosis of the shaft limit switch which is the first block is carried out. As the diagnosis item 1, operation and position confirmation of the lowermost floor limit switch 3LS are executed (ST23). The lowermost floor limit switch 3LS is a limit switch for forcibly decelerating so that the car 4 does not move below the predetermined position, and it is diagnosed whether the on / off operation is correctly performed and the position confirmation is accurate. Do (D2). When the diagnosis item 1 is completed, the diagnosis result is stored in the diagnosis result storage unit 36.

  Next, as the diagnosis item 2 of the first block, confirmation of the limit switch installed on each floor is carried out while ascending operation to the uppermost floor TF (ST24). In this diagnosis, it is judged whether or not the hoistway limit switch of each floor is correctly turned on and off, and whether the position confirmation is correct (D3). In this case, since the diagnosis of the hoistway limit switch of each floor constitutes one diagnostic item, the diagnosis result is stored in the diagnosis result storage unit 36 each time the diagnosis of one limit switch is completed.

  Next, when the car 4 arrives at the top floor TF, operation and position confirmation of the top floor limit switch 4LS are performed (ST25). In this diagnosis, the top floor limit switch 4LS is a limit switch for forcibly decelerating so that the car 4 does not move above the predetermined position, and whether or not the on / off operation is accurately performed, the position confirmation is accurate To diagnose (D4). The diagnosis of the shaft limit switch at the time of rising from the lower floor BF to the uppermost floor TF is the first diagnostic block. The diagnosis result is stored in the diagnosis result storage unit 36 each time the shaft limit switch is diagnosed.

  Then, when the diagnosis of the first block is completed, the diagnosis result data is created by the data editing unit 37 and transmitted to the monitoring center 10.

  Also, while the diagnosis result is read from the diagnosis result storage unit 36 and diagnosis result data is created and transmitted to the monitoring center 10, diagnosis of the next second block is performed in parallel. In this way, the diagnostic items of all blocks constituting the remote diagnostic operation are completed.

  In step ST26, a brake diagnosis that is a diagnosis of the second block is performed. In the brake diagnosis, without releasing the brake Br installed in the hoisting machine 8, torque is applied to the hoisting machine 8 while the car 4 is stopped, and confirmation processing that the holding power of the brake is normal is carried out Be done (D5).

  Then, when the diagnosis of the second block is completed, the diagnosis result data is created by the data editing unit 37 and transmitted to the monitoring center 10. The diagnosis item of the second block is a brake diagnosis and there is only one diagnosis item. While the diagnosis result is read from the diagnosis result storage unit 36 and the diagnosis result data is created and transmitted to the monitoring center 10, the diagnosis of the next third block is performed in parallel.

  In the next step ST27, processing for confirming the operation of the hoistway limit switch (descent), which is the third diagnostic block, is performed. In this process, diagnosis and position confirmation are carried out as to whether or not the limit switch of each floor operates normally while traveling the car 4 to the lower floor BF (D6). As with the first diagnosis block, the diagnosis of the shaft limit switch of each floor constitutes one diagnosis item, so that the diagnosis result is stored in the diagnosis result storage unit 36 each time the diagnosis of one limit switch is completed.

  When the diagnosis of the third block is completed, the diagnosis result data is created by the data editing unit 37 and transmitted to the monitoring center 10. While the diagnosis result is read from the diagnosis result storage unit 36 and the diagnosis result data is created and transmitted to the monitoring center 10, the diagnosis of the next fourth block is performed in parallel.

  In step ST28, diagnosis of the fourth block, which is the last diagnostic block, is performed. In this diagnosis, the car 4 is stopped at each floor, and it is confirmed whether each floor door operates normally. That is, in each floor door diagnosis, confirmation of the door open / close state, door torque confirmation, and each door switch operation position confirmation processing are performed (D7). The diagnosis result is stored in the diagnosis result storage unit 36.

  Then, when the diagnosis of the fourth block is completed, the diagnosis result data is created by the data editing unit 37 and transmitted to the monitoring center 10. When door confirmation of all floors is completed, all the diagnostic operations are completed and the normal operation is restored (ST 29).

  If the user presses the elevator hall call button in an attempt to use the elevator during diagnosis of a diagnosis item, the remote diagnosis operation is interrupted and the call is answered, and then the remote diagnosis operation is started from the interrupted diagnosis item. Resume However, when the number of times the call button is pressed is large, the remote diagnosis operation is stopped. In this case, since diagnostic data of a block which has been completed up to that point is transmitted, when retrying remote diagnosis operation, it may be performed from the canceled block, and efficient diagnosis can be performed.

  Moreover, although the diagnostic block was comprised by four of the 1st-4th block in a present Example, it is not restricted to this. For example, the rated speed diagnosis may be performed while the car is moving up.

<Division edit of diagnosis result>
In the embodiment described above, diagnosis of the hoistway limit switch is performed in the first block and the third block. In the case where the number of installed shaft limit switches is large, if diagnosis result data is transmitted to the monitoring center 10 after diagnosis of one block is completed, the transmission capacity increases and the transmission time becomes long.

  In this case, the data editing unit 37 divides one block into a plurality of blocks, and transmits diagnostic result data to the monitoring center 10 in units of divided blocks. Thereby, shortening of transmission time can be achieved and reliable transmission is possible. In addition, the number of retries can be reduced, and transmission costs can be reduced.

  In the above embodiment, although the first, second and fourth blocks are composed of a plurality of diagnostic items and the diagnostic result is transmitted, one block is composed of one diagnostic item like the brake diagnosis of the third block. The diagnostic result data may be transmitted to the monitoring center 10 in diagnostic item units.
