JP 2007-84245 A

  The present inventors examined maintenance work in an elevator system in which a plurality of elevator apparatuses are installed side by side. Hereinafter, when the term “maintenance” is used in the present specification, it means both maintenance and / or inspection of the elevator apparatus.

  One of the elevator maintenance work is called a car work. A handrail or the like is provided on the elevator car. When necessary, maintenance personnel get on the car and perform work on the car.

  Among the work performed on the car, there are maintenance such as inspection of the elevator cooler, inspection of the outer frame of the car, loose tightening of the handrail inside the car, and in this case, the maintenance staff is on the side of the adjacent elevator system on the car. It is necessary to work slightly outside the body. Such work is particularly called “overhanging work”.

  On the other hand, when performing maintenance of an elevator system in which a plurality of elevator apparatuses are installed in parallel, it is desirable that the maintenance target car is in the maintenance mode and the adjacent car is maintained in the normal operation mode. This is because at least the service of the user is continued by the adjacent unit. However, when performing an overhang operation, it is necessary to stop the operation of the adjacent unit in order to ensure the safety of maintenance personnel.

  Inventors of the present application give priority to ensuring the safety of maintenance personnel, and if there is an overhanging work on the menu of maintenance work, it is considered that adjacent units that are not subject to maintenance are also interrupted during the maintenance work did.

  Since it was necessary to access the hall on the first floor and the control panel of each elevator to interrupt the operation of the adjacent unit, temporarily interrupting the operation of the adjacent unit during maintenance work is rather efficient for the overall maintenance work. This is because of lowering. For this reason, during the maintenance work over several hours, the maintenance target machine and the adjacent car cannot be used, and there is a problem that the service for the user, that is, the user during the maintenance work is deteriorated.

  In addition, if the service drop for users on business days cannot be tolerated, maintenance work is performed with the date and time restricted, which causes problems such as reduced maintenance efficiency and increased maintenance costs. It was.

  In addition, when the operating range is limited as described in Patent Document 1, there is a concern that the counterweight and rope of the adjacent machine are operating, and in order to ensure the safety of maintenance personnel by the overhanging work It is desirable to stop the operation of the adjacent unit. The prior art described in Patent Document 1 requires detection means, and providing the detection means only for maintenance in this way is problematic in terms of cost.

  The present invention has been made based on the above-described situation in the prior art, and an object of the present invention is to provide an elevator system capable of interrupting the operation of the adjacent unit without reducing the service to the user as much as possible, and a maintenance method thereof. is there.

  To achieve the above object, an elevator system according to the present invention includes a first car, a first control panel for controlling the operation of the first car, and a first communication for accessing the first control panel from the outside. A first elevator device having an interface; a second car; a second control panel for controlling the operation of the second car; and a second communication interface for accessing the second control panel from the outside. A second elevator device adjacent to one elevator device, and a maintenance terminal accessible to the first and second communication interfaces on the first car or the car of the second car, the maintenance terminal comprising: An operation interruption command for accessing the second control panel via the second communication interface and interrupting the operation of the second elevator apparatus to stop the second car at a predetermined floor. It is characterized by having a command.

  In the elevator system maintenance method of the present invention, the operation of the second elevator apparatus is interrupted with respect to the second control panel that controls the operation of the second car of the second elevator apparatus, and the second elevator panel is operated. The operation stop command for stopping the car at the predetermined floor is transmitted from the maintenance terminal, and the second elevator apparatus that has received the operation stop command confirms that there are no people in the second car, The second car on the predetermined floor is stopped, and the maintenance terminal receives the information indicating that the second car is stopped transmitted from the second elevator device, and receives the information indicating that the second car has been stopped. An input means for allowing maintenance personnel to input that the stoppage of the apparatus has been confirmed is displayed on the screen, and the maintenance staff inputs via the input means that the operation interruption of the second elevator apparatus has been confirmed. After Tsu, it is characterized by carrying out the protruding work performed protrude the body from the first elevator device of the first car on-car.

  The elevator system and the maintenance method thereof according to the present invention can interrupt the operation of an adjacent elevator device from the top of the car by the operation interruption command of the maintenance terminal at the timing when the operation of the elevator device to be maintained is performed on the car. it can. Thereby, the operation interruption time of an adjacent elevator apparatus can be shortened. That is, according to the present invention, it is possible to interrupt the operation of the adjacent car without reducing the service to the user as much as possible.

  Further, according to the present invention, since the adjacent elevator apparatus can be stopped and the protruding work can be performed, the safety of maintenance personnel can be ensured. Problems, configurations, and effects other than those described above will become apparent from the following description of embodiments.

It is a figure showing the whole elevator system composition of Example 1 concerning the present invention. 1 is a logical connection diagram of an entire elevator system according to a first embodiment of the present invention. It is a flowchart which shows the procedure of the preparation of the overhang | projection operation | work of Example 1 which concerns on this invention. It is a flowchart which shows the procedure of the withdrawal operation | work of Example 1 which concerns on this invention. It is a figure which shows the state of the inspection object number machine in the elevator system of 3 parallel and 4 parallel of Example 2 which concerns on this invention.

  Embodiments of an elevator system and a maintenance method thereof according to the present invention will be described below with reference to the drawings.

[Example 1]
First, an elevator system in which two elevator apparatuses are installed in parallel in one elevator hall will be described as an example. In the first embodiment, when the maintenance worker 103 performs a projecting operation from the first elevator apparatus, for example, the first car of the A-unit 101A, that is, the car 110A, the second elevator apparatus is used by using the maintenance terminal 102. For example, a case where the operation of the second car of the B machine 101B, that is, the operation of the car 110B is interrupted will be described.

  FIG. 1 is a diagram showing an overall configuration of an elevator system according to a first embodiment of the present invention. As shown in FIG. 1, in the elevator system 100 of the first embodiment, two units, an A-unit 101A and a B-unit 101B, which constitute an elevator apparatus, are arranged in parallel. Reference numerals A and B in FIG. 1 and FIG. 2 to be described later identify the A machine 101A and the B machine 101B, respectively. Or both. In this case, the A machine 101A and the B machine 101B are described as an elevator apparatus 101 as necessary.

  The elevator apparatus 101 shown in FIG. 1 employs, as an example, a balance raising / lowering method in which a car 110 is raised and lowered in a hoistway by a balance of a counterweight 113 by a hoisting machine 112 via a main rope.

  The car 110 includes a monitoring camera 111 installed near the ceiling of the car 110 and a load sensor 117 installed under the floor of the car 110 to detect a load load.

  Further, the elevator apparatus 101 includes a control panel 115 that controls the operation of the car 110, and a driving apparatus 116 that drives the hoisting machine 112 in accordance with a control signal from the control panel 115.

  A first communication interface, for example, a wireless module 114A is connected to the control panel 115A, and a second communication interface, for example, a wireless module 114B is connected to the control panel 115B, and an external device is connected via these wireless modules 114A, 114B. Information can be transmitted and received between the wireless terminal and the control panels 115A and 115B.

  The first embodiment shows a case where maintenance of the A-unit 101A is performed. A maintenance staff 103 is present on the cage 110A of the A-unit 101A and has a maintenance terminal 102 which is a kind of wireless terminal. .

  The maintenance terminal 102 is connected to the wireless module 114A of the No. A machine 101A and the wireless module 114B of the No. B machine 101B according to a known standard such as a wireless LAN, and can transmit and receive information. Although the maintenance terminal 102 is not particularly limited, it is a maintenance-dedicated device, and communication has special security protection.

  As an example, the wireless module 114 of the first embodiment is provided in the elevator operation panel of the first floor elevator hall. Although the installation location of the wireless module 114 is not particularly limited, it is assumed that the car 110 can be transmitted to and received from the maintenance terminal 102 anywhere in the hoistway. In some cases, a plurality of wireless modules 114 and boosters may be provided in the hoistway.

  As described above, the maintenance terminal 102 can access the wireless module 114 in the hoistway.

  FIG. 2 is a logical connection diagram of the entire elevator system according to the first embodiment of the present invention. In FIG. 2, solid arrows connecting the components indicate wired signal paths, and dotted arrows indicate wireless signal paths. In FIG. 1, some wirings are omitted so as not to complicate the figure, but are clarified in FIG.

  As shown in FIG. 2, the control panel 115 includes an input / output unit (I / O) 201, a calculation unit (CPU) 202, and a storage unit (MEM) 203.

  The input / output unit 201 typically includes an electrical input / output circuit for connecting to the wireless module (WM) 114, the monitoring camera 111, the load sensor 117, the driving device 116 of the hoisting machine 112, and the like. It is out. In accordance with a signal input via the input / output unit 201, the calculation unit 202 performs a predetermined process using a predetermined program stored in the storage unit 203.

The operation of each part will be described below with an elevator during normal operation as an example.
First, when a button on an elevator operation panel (not shown) (elevator call button in the elevator hall, destination floor button in the car 110, etc.) is pressed, the instruction of the button is controlled via one circuit of the input / output unit 201. It is transmitted to the board 115.

  The calculation unit 202 of the control panel 115 generates a signal necessary for the operation of the car 110 based on the button instruction and the current position of the car 110, and again through another circuit of the input / output unit 201. The drive unit 116 of the hoisting machine 112 is instructed.

  The driving device 116 transmits a signal for driving the motor of the hoisting machine 112, so that the car 110 of the elevator apparatus 101 moves up and down to a predetermined floor according to a button on the operation panel.

  The maintenance terminal 102 according to the first embodiment includes a wireless module (WM) 204, an input / output unit (I / O) 205, a calculation unit (CPU) 206, a storage unit (MEM) 207, and a display unit (LCD) such as a liquid crystal display. 208, including an input means, that is, an input unit (IN) 209.

  The input unit 209 may be a mouse, a trackball, or a keyboard, and a touch interface using buttons and a keyboard displayed on the display unit 208 is one of particularly preferable modes. The wireless module 204 is wirelessly connected to the No. A machine 101A and the No. B machine 101B according to a known standard such as a wireless LAN. Note that the wireless module 204 can also be called a communication interface as a more general function. A well-known tablet terminal is a typical example of means for realizing the maintenance terminal 102.

  The maintenance terminal 102 stores a predetermined program in the storage unit 207 and displays on the display unit 208 a graphic user interface (GUI) for issuing a command for controlling the operation of the No. A machine 101A and the No. B machine 101B.

  When the maintenance staff 103 makes a predetermined input to the input unit 209, a command signal is issued from the maintenance terminal 102 to the control panel 115 via the wireless module 114 of the elevator apparatus 101.

  In response to the command signal, the arithmetic unit 202 of the control panel 115 executes a predetermined program in the storage unit 203 to perform a predetermined operation.

  For example, as will be described later, when the maintenance terminal 102 issues an “operation interruption command” to Unit B 101B, the control panel 115B executes the operation interruption program stored in the storage unit 203b, and there is no one in the car 110B. After confirming this, the car 110B is stopped on the predetermined floor.

  Further, the maintenance terminal 102 sends a predetermined command signal to the elevator apparatus 101 to acquire internal information of the elevator apparatus 101 (the floor where the car 110 exists, video information of the monitoring camera 111, etc.) from the control panel 115. Are displayed on the display unit 208, and the maintenance staff 103 can use them for maintenance work.

  FIG. 3 is a flowchart showing a preparation procedure for the overhang work according to the first embodiment of the present invention. The procedure shown in FIG. 3 is a situation in which the machine A 101A is in the maintenance mode and the maintenance staff 103 occupies it for maintenance and cannot be used by the user, and the machine B 101B continues the service to the user in the normal operation mode. Has been started from.

  The maintenance staff 103 calls a setting screen for preparation of the overhanging work in the No. A machine 101A to the display unit 208 of the maintenance terminal 102, and preparation for the overhanging work in the No. A machine 101A is started (S301).

  In this setting screen, the maintenance staff 103 issues an “operation prohibition command” to the A machine 101A and issues an “operation interruption command” to the B machine 101B from the maintenance terminal 102 (S302).

  Here, the “operation prohibition command” is an instruction for prohibiting the reception of a command related to the operation of the car 110A, and the “operation interruption command” is the details of the car 110B which will be described later in S304 to S309. This is an instruction to stop the floor

  Receiving the “operation prohibition command”, Unit A 101A prohibits acceptance of commands related to the operation of Unit A 101A until certain conditions are met so that Unit A 101A is not erroneously operated before Unit B 101B stops. The No. A machine 101A is set in the “operation disabled” state (S303).

  It should be noted that even in the “operation disabled” state, it is possible to execute a command for reading the internal data of the operation panel of the No. A machine 101A that is not related to the operation of the car 110A.

  The “operation disable” of the No. A machine 101A is an interlock for the safety of the maintenance staff 103.

  Furthermore, Unit B 101B determines whether or not there is a person in the car 110B based on the image processing of the monitoring camera 11B (difference video for each of the empty car video standard and the person) and the load value signal of the load sensor 117B. (S307).

  When prohibiting a new car call reservation, it is preferable to indicate to the user that the elevator has become unusable by displaying “inspection” or the like on the elevator hall indicator. If there is no person in the car 110B in S305, it is confirmed whether there is a call reservation for the car 110B of the No. B machine 101B (S306). If there is a reservation for a car call, S307 described above is executed.

  When there is no car call reservation in S306 and when execution of S307 is completed, the car 110B of Unit B 101B is stopped at the nearest floor, that is, a predetermined floor, and the operation interruption routine of Unit B 101B is completed (S308). ).

  Further, after the end of S308, the B machine 101B notifies the maintenance terminal 102 that the interruption of the operation of the B machine 101B has been completed (S309). As a result, the maintenance staff 103 is notified that the preparation for the overhanging work has been completed.

  The maintenance terminal 102 displays a screen for inputting confirmation of operation interruption of the No. B machine 101B (S310). More specifically, a button for inputting that the maintenance staff 103 has confirmed that the operation of the Unit B 101B has been interrupted is displayed on the display unit 208 of the maintenance terminal 102 to prompt the maintenance staff 103 to confirm.

  Further, in order to indicate to the maintenance staff 103 that there is no person in the car 110B of the Unit B 101B, the maintenance terminal 103 may receive the video of the monitoring camera 111B of the Unit B 101B and display it on the display unit 208. This is a more desirable configuration to inform the situation.

  Furthermore, it is also desirable to generate a predetermined sound or chime from the maintenance terminal 102 or the like in order to notify the maintenance staff 103 that the preparation for the overhanging work has been completed in a timely manner.

  When the maintenance person 103 presses the confirmation button for stopping the operation of Unit B 101B in S310, the maintenance terminal 102 issues a “cancel command” of the operation prohibition command to Unit A 101A, and issues an “operation prohibition command to Unit B 101B. Is issued (S311).

  Receiving the “release command”, Unit A 101A releases “Operation Disable” to release the safety interlock, while Unit B 101B receiving the “Operation Disable Command” “Disable” is set, and the interlock is applied to the B machine 101B (S312).

After this, the maintenance staff 103 starts the overhanging operation in the Unit A 101A, but if the maintenance staff 103 accidentally issues a command that causes the car 110B of the Unit B 101B to operate, the Unit B 101B Since it is locked, it does not operate and the safety of the maintenance staff 103 is further increased. Thus, the preparation for the protruding operation of the No. A machine 101A is completed (S313).

  Although the above-described preparation for the overhanging operation depends on the situation such as the car call reservation of the No. B machine 101B, if there is no person in the No. B machine 101B and there is no car call reservation, the preparation is completed in a short time within one minute.

  FIG. 4 is a flowchart showing a procedure for withdrawing the protruding work of the first embodiment according to the present invention. FIG. 4 shows a procedure for restarting the operation of the No. B machine 101B that has been suspended until the completion of the overhanging operation of the No. A machine 101A.

  First, the maintenance staff 103 calls a setting screen for withdrawing the protruding work in the A-unit 101A to the display unit 203 of the maintenance terminal 102, and starts this work (S401).

  There is a predetermined button on the setting screen, and an operation prohibition command “cancel command” is issued from the maintenance terminal 102 to Unit B 101B by the sled button (S402).

  Receiving the “cancel command”, Unit B 101B cancels “operation disable” and resumes operation, and shifts to the normal operation mode (S403). As described above, the withdrawal of the protruding work of the No. A machine 101A is completed.

  The procedure for resuming the operation of Unit B 101B, which has been interrupted as described above, is completed in about one minute because there is no particular factor to change.

  The time for the overhanging operation to be performed while restarting the operation after stopping the Unit B 101B is about 10 minutes. Therefore, the operation interruption time can be greatly reduced and the service degradation of the user can be minimized as compared with the operation interruption of the adjacent B machine 101B for several hours for maintenance of the A machine 101A. Can do.

The effects obtained in Example 1 are as follows.
(1) Since the operation of the adjacent B machine 101B can be interrupted by the operation interruption command of the maintenance terminal 102 from the car of the A machine 101A at the timing when the maintenance target projecting operation is performed. The operation interruption time of 101B can be shortened. That is, the operation of the adjacent No. B machine 101B can be interrupted without reducing the service to the user as much as possible. Moreover, since the adjacent B machine 101B can be stopped and the protrusion work can be performed, the safety of the maintenance staff 103 is ensured.

(2) When the maintenance terminal 102 issues an operation interruption command, an operation prohibition command for prohibiting the operation of the car 110A of the maintenance target A machine 101A is issued in parallel to interrupt the operation of the adjacent B machine 101B. It is possible to eliminate the danger caused by accidentally operating the machine A 101A to be maintained before the completion of.

(3) When the adjacent Unit B 101B is interrupted and stopped at the predetermined floor, the maintenance terminal 102 is notified of this, so the maintenance staff 103 knows when the overhanging operation can be started safely in the shortest time. be able to.

(4) When the adjacent Unit B 101B suspends operation and stops at a predetermined floor, input means for allowing the maintenance staff 103 to confirm the situation is displayed on the maintenance terminal 102, and the fact that the maintenance staff 103 has confirmed is entered. Thus, the operation prohibit command set in the maintenance target machine A 101A can be canceled, so that the interlock can be released in the shortest time and the maintenance target protrusion work can be started.

[Example 2]
In the first embodiment, the case where the two elevator apparatuses A 101A and B 101B are arranged in parallel is shown, but the case where the number of elevator apparatuses is further increased will be described in the second embodiment. Basically, stopping the adjacent elevator apparatus is the same, but the procedure from S305 to S307 in FIG. 3 can be simplified and shortened depending on the situation, and is different from the first embodiment.

  FIG. 5 (a) shows a case where three elevator apparatuses, that is, No. A, No. B, and No. C are installed in a line while sharing one elevator hall.

  When inspecting Unit A, adjacent Unit B must be stopped during the overhanging operation as in Example 1, but Unit C, which is not adjacent, can always operate.

  In such a situation, since the car call reservation before the operation interruption may be shared by the Unit C, S306 for processing the car call reservation becomes unnecessary. In addition, the operation for the reservation in S307 is shared by Unit C.

  For this reason, if it operates so that there may be no person in a cage | basket | car, S308 can be performed, Therefore The time until the driving | operation interruption of the B machine can be shortened. The above situation is the same when checking Unit C from the adjacent relationship.

  On the other hand, when inspecting Unit B, since the operation of Units A and C adjacent on both sides must be interrupted, the same procedure as in FIG. 3 is required.

  There are also cases where two rows in parallel (No. A and No. B) and one (No. C) are installed via one elevator hall. At this time, since there are units that are not always adjacent, S306 is unnecessary, and the operation for the reservation in S307 is also unnecessary, so the time until the operation is interrupted can be shortened.

  FIG. 5B shows a case where four elevator apparatuses, that is, No. A, No. B, No. C, and No. D machines are installed in a line while sharing one elevator hall. In such a situation, when checking any of Unit A to Unit D, there is a unit that is not adjacent, so S306 in FIG. 3 is not necessary, and there is no need to operate the car call reservation in S307. .

  There are cases where two units are installed in parallel (No. A and B) and two in parallel (No. C and No. D) with one elevator hall in between. At this time, since there are units that are not always adjacent, S360 is unnecessary, and the operation for the reservation in S307 is also unnecessary, so the time until the operation is interrupted can be shortened.

  From the above example, if there are 5 or more elevator devices, S306 is similarly unnecessary, and the operation for the reservation in S307 is also unnecessary, so the time until operation interruption is similarly reduced. Can be made.

  In summary, when three or more elevator devices are arranged, it is often possible to shorten the time until the operation is interrupted as compared to the two-unit arrangement.

  A building or the like where many elevator devices are installed has a large number of elevators, and it is better to shorten the operation interruption as much as possible. In that sense, the invention described in the first embodiment is useful even when there are three or more elevator apparatuses.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.

  Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.

  The specific operation description of the first embodiment is that any one elevator apparatus when there are two or more elevator apparatuses is the first elevator apparatus to be maintained, and the elevator apparatus adjacent to the first elevator apparatus is the first one. Of course, this is applied to the case of a two-elevator device.

  In the first embodiment, the maintenance terminal 102 accesses the wireless module 114 wirelessly, but this may be wired. That is, the wireless modules 114A, 114B, and 204 may be replaced with wired LAN interface circuits, and for example, a star network may be configured in which the three locations of the maintenance terminal 102, the control panel 115A, and the control panel 115B are communicated in a wired manner.

  In this case, a connector as a cable end for connecting the maintenance terminal 102 to the wired LAN is prepared on the car 110. In this sense, an interface circuit in the case of using the wireless modules 114A, 114B, and 204 or a wired LAN can be called a “communication interface” in a broad concept. However, a wired LAN is expensive in order to lay a wired cable in an existing elevator apparatus. In that respect, the wireless configuration of the first embodiment is advantageous.

  Note that the wireless communication interface between the maintenance terminal 102 and the control panel 115 according to the first embodiment is employed with various other merits, and is not performed only to enable “overhanging work”. . For this reason, wireless is not a bottleneck in cost.

  In the first embodiment, the operation interruption command issued by the maintenance terminal 102 is an instruction for starting the operation interruption routine program (S304 to S309 in FIG. 3) stored in the storage unit 203A in the control panel 115A of the No. A machine 101A. . However, as a method for implementing the operation interruption command, the maintenance terminal 102 has an operation interruption routine program. When necessary, the maintenance terminal 102 transfers the program to the control panel 115, or the maintenance terminal 102 executes the program to execute individual programs. A method of sending a command for performing a specific operation corresponding to S304 to S309 to the control panel 115 is also possible.

  However, since the program including the instruction related to the elevator control needs to detect the actual car position information, as described in the first embodiment, the control panel 115 has the operation interruption routine program as the control separation. Is reasonable.
