Description

  The present invention relates to an elevator that performs group management control and has a function of specifying a car to be maintained.

  Conventionally, when an elevator maintenance worker tries to secure a car subject to maintenance by registering at the hall call to perform car maintenance, the group management elevator does not know which unit will respond. The unit may respond. In this case, the hall call must be registered again, which may reduce maintenance efficiency and service to customers.

In order to improve this problem, as disclosed in, for example, Patent Document 1, there is one that designates a car to be maintained by performing a different operation on a hall call button installed at a hall. In addition, as disclosed in, for example, Patent Document 2, an arrival car designating device is newly provided at the landing, and a car to be maintained is designated by the arrival car designating device and responds to the floor where the elevator maintenance staff is located. There is.
Japanese Patent Laid-Open No. 7-10399 Japanese Patent Laid-Open No. 9-156842

  However, as described above, the method of designating the car to be maintained by operating the hall call button is different from the normal operation because only the UP button or DN button is installed on the top floor or the bottom floor. It is difficult to specify a car by performing an operation, and it is not possible to determine whether or not the car has been registered.

  In addition, as described above, when the arrival car designating device is provided at the landing, it is necessary to newly provide an operation device at the landing, so that it is considered that there is an adverse effect in terms of cost and landing design.

  Accordingly, an object of the present invention is to secure a maintenance target car among the cars subject to group management control without requiring a new operation device without lowering maintenance efficiency and lowering service to customers. Is to provide an elevator to become.

  That is, the elevator according to the present invention has different maintenance inspection targets depending on the car provided with the destination call button operated according to the operation of the destination call button of any of the plurality of cars that are moved up and down according to the group management control. A car is designated, and the designated car is caused to respond to a predetermined floor.

  According to the present invention, it is possible to secure a maintenance target car among the cars subject to group management control without requiring a new operating device without lowering maintenance efficiency and lowering service to customers.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram illustrating a configuration example of an elevator according to an embodiment of the present invention. In FIG. 1, the configurations existing in each unit are distinguished by adding subscripts a and b.

  As shown in FIG. 1, an elevator according to an embodiment of the present invention includes a group management control panel 1, a single control panel 2 for each car, and a car 3. In the car 3, an in-car operation panel 4 and a maintenance BOX 5 are provided.

The car 3 ascends and descends in the opposite direction with the counterweight as the sheave rotates by driving the hoisting machine. The driving system of the car 3 may be another system such as a hydraulic system.

  The single control panel 2 of each unit includes a car control unit 11 that controls the car 3 of the own unit. The car control unit 11 includes a dispatch car registration unit 19. The in-car operation panel 4 of each car is provided with a destination call button 12 for registering the destination of the car 3 and a door opening / closing button 13 for opening and closing the door. The operation of the button 13 causes the car 3 to travel to the destination floor and to open and close the door.

  A hall call button 15 and a lantern 16 are installed at the hall 6 of each floor. The group management control panel 1 includes a group management control unit 14 that performs assignment control for assigning the optimal car 3 to the hall call registered by operating the hall call button 15. The group management control unit 14 includes a group management separation control unit 18 and a dispatch car control unit 20.

  The car control unit 11 in the single control panel 2 is connected to the group management control unit 14, the hall call button 15 and the lantern 16 on each floor. The maintenance box 5 in the car 3 is provided with a maintenance mode switch 17 for switching the operation mode of the car 3 between the normal operation mode and the maintenance mode.

  When the switch is operated to switch to an on state or an off state, a signal indicating that the switch has been performed is output to the group management disconnection control unit 18 of the group management control unit 14. The group management control unit 14 sets the operation mode of the operating car 3 to the normal operation mode when the maintenance mode changeover switch 17 is in the off state, and when the maintenance mode changeover switch 17 is in the on state. Set the operation mode to maintenance mode.

  In addition, the car allocation unit 19 of the car control unit 11 has a predetermined number for designating a maintenance target car for the destination call button 12 or the door opening / closing button 13 when the operation mode is switched to the maintenance mode as described above. When an operation is performed, the car information and floor information, which are the car information of the maintenance target car associated in advance with the operation, are registered.

  The car information of the car information indicates the type of the car to be maintained, and the floor information indicates the floor to which the car is assigned. The car 3 corresponding to the registered number information is different depending on the car provided with the operated destination call button 12 and the like.

  Then, when the maintenance mode changeover switch 17 in the car 3 of the own car is returned to the OFF state by the operation of the maintenance staff, the dispatch car registration unit 19 stores the registered car information as described above. 14 to output.

  The car allocation control unit 20 of the group management control unit 14 instructs to exclude the car 3 corresponding to the car information indicated by the car information from the car allocation unit 19 of the car control unit 11 from the assignment target of the hall call. Is output to the group management separation control unit 18 in the group management control unit 14, and a vehicle dispatch command for dispatching to the floor indicated by the floor information of the car information is a single control panel corresponding to the above-mentioned unit information 2 to the car control unit 11.

Next, a series of operations until the maintenance staff of the elevator having the configuration shown in FIG. 1 secures a car to be maintained will be described. In the elevator according to the present embodiment, it is assumed that there are four passenger cars 3 from No. A to No. D, and the building configuration is B1F to 10F.
FIG. 2 is a flowchart showing an example (part 1) of a process related to a response of the elevator maintenance target car in the embodiment of the present invention.
In FIG. 2, a procedure from when the car information of the maintenance target car is registered by the elevator maintenance staff until the registered information is output to the group management control unit 14 is described.

FIG. 3 is a flowchart showing an example (part 2) of the processing relating to the response of the elevator maintenance target car in the embodiment of the present invention.
FIG. 3 illustrates a flow until the car 3 of the maintenance target car responds to the elevator maintenance staff with respect to the registered car information.

  First, the maintenance mode switch 17 is off in the initial state. In order to register the car information, the elevator maintenance person gets on any car 3 and switches the maintenance mode switch 17 to the on state.

  A signal indicating this switching is output from the maintenance mode changeover switch 17 to the group management disconnection control unit 18 of the group management control unit 14 via the car control unit 11. This signal includes information on the installed machine number of the operated maintenance mode changeover switch 17.

  When the signal from the maintenance mode changeover switch 17 is input, the group management disconnection control unit 18 determines that the operation mode of the unit indicated by the input signal is in the maintenance mode (YES in step S1), and the unit is disconnected. Excluded from assignment of hall call. Further, when the mode is not switched to the maintenance mode, subsequent car information registration processing cannot be performed (NO in step S1).

  In accordance with the operation of the destination call button 12 and the door opening / closing button 13 by the maintenance staff, the car of a different car number from the own car by the dispatch car registration part 19 of the car control part 11 of the car mode control part 11 installed in the maintenance mode change switch 17 operated as described above. When the information is registered (step S2) and the maintenance mode changeover switch 17 is returned to the off state (step S3), the dispatched car registration unit 19 determines the existence of the car information (step S4).

  When the car information is registered (YES in step S4), the dispatched car registration unit 19 performs group management control together with the information on the car number, that is, the installed car number of the operated maintenance mode changeover switch 17. It outputs to the part 14 (step S5).

  Then, the group management disconnection control unit 18 of the group management control unit 14 cancels the exclusion from the assignment target of the hall call set for the car indicated by the information on the installed car from the allocation car registration part 19, It is determined that the maintenance mode has been released and the unit is returned to normal operation (step S6).

  Further, the dispatched car registration unit 19 determines that the car information is not registered as a result of the process of step S4, that is, the maintenance mode changeover switch 17 is returned to the OFF state without the car information being registered by the process of step S2. If it is determined (NO in step S4), a signal indicating the name of the own machine is output to the group management control unit 14. After this process, the process proceeds to step S6.

Details of the car information registration process, which is the process of step S2, will be described.
There are two methods for registering the car information: a method of registering only the unit information of the maintenance target unit, and a method of individually registering the unit information and floor information of the maintenance target unit.
First, as a first example, a method for registering only unit information of a maintenance target unit will be described with reference to FIG. FIG. 4 is a flowchart showing a first example of the car information registration process for the elevator maintenance target in the embodiment of the present invention.
As described above, the elevator maintenance staff presses the door close button while pressing the door open button of the door open / close button 13 of the in-car operation panel 4 of the car number on the maintenance mode switching switch 17 switched to the ON state, and presses the door close button. When the dispatched car registration unit 19 of the car control unit 11 detects the pressing (step S31), the dispatched car registration unit 19 sets the operation mode to a mode in which car information can be registered according to the operation of the in-car operation panel 4. The operated door open button is turned on (step S32). As a result, the maintenance staff can visually recognize that the car information of the maintenance target car can be registered.

FIG. 5 is a diagram showing a relationship between a destination call button of an elevator car in the embodiment of the present invention and a car name designated as a maintenance target when the button is operated.
The dispatch car registration unit 19 of each car holds information indicating the association between the destination call button 12 and the car name shown in FIG. However, the car occupancy registration unit 19 of each car separately holds information that the relation between the car number and the destination call button 12 is invalid among the relations shown in FIG.

The maintenance staff grasps the information indicating the relation, and presses the destination call button 12 corresponding to the maintenance target car different from the car on which the car is riding. When the dispatched car registration unit 19 of the car control unit 11 of the installed car number control unit 11 of the pressed destination call button 12 detects the press (step S33), the association between the destination call button 12 and the car name shown in FIG. Based on the information shown, the name of the car related to the pressed destination call button 12 is held in the internal memory as the selected car to be maintained, and the pressed destination call button 12 is turned on (step S34). Thus, the maintenance staff can visually recognize that the maintenance target machine has been selected.
Note that the number of units that can be simultaneously selected as maintenance target units may be single or plural. When selecting a plurality of maintenance target machines, the maintenance staff may press the destination call buttons 12 corresponding to the respective cars.

  When it is determined that there is no selection mistake (YES in step S35), the maintenance staff presses the door open button in the car 3. When the car dispatching car registration unit 19 of the own car detects the pressing (step S36), the car information registration part 19 registers car information in the internal memory (step S37).

  The car information described here is machine information and floor information. The machine number information is information indicating the selected number of maintenance machines held in the process of step S34. The floor information is information that indicates the floor at which the car 3 that has performed the operation for registering the car information is currently stopped, and is uniquely determined. Further, the floor information may be fixed information such as the top floor or the bottom floor.

  When the car allocation register 19 performs the car information registration process, it turns off the door open button that was lit in the process of step S32 and the destination call button 12 that was lit in the process of step S34 (step S38).

  If the maintenance person judges that the registered content is incorrect after registration of the car information, that is, after the lit door open button is turned off (NO in step S39), the door opening / closing of the operation panel 4 in the car is opened and closed. While pressing the door open button of the button 13, the door close button is pressed (step S39 → S31). When the dispatched car registration unit 19 detects the pressing, the car information registered in the process of step S37 is deleted. After erasing the car information, the process proceeds to step S32.

  Also, the maintenance staff cancels the selection when it is determined that there is an error in the operation of the destination call button 12 for selecting the maintenance target machine before registration is completed, that is, when the door open button is lit. If desired (NO in step S35), the door close button is pressed.

  When the dispatching car registration unit 19 detects pressing of the door closing button (step S40), the door opening button lit in the process of step S32 and the destination call button 12 lit in the process of step S34 are turned off and held. The selected car information is deleted, and the car information registration mode in the own car is released (step S41).

Next, as a second example of the car information registration method, a method of individually registering the maintenance target car information and floor information will be described with reference to FIG. FIG. 6 is a flowchart showing a second example of the car information registration process of the elevator maintenance target car in the embodiment of the present invention.
The elevator maintenance staff presses the door close button while pressing the door open button of the door open / close button 13 of the car operation panel 4 of the car number installed on the maintenance mode changeover switch 17 switched to the ON state as described above, and the own machine When the vehicle dispatching car registration unit 19 detects the pressing (step S51), the car dispatching car registration unit 19 sets the operation mode to a mode in which car information can be registered according to the operation of the in-car operation panel 4, and is operated. The door open button is turned on (step S52).

  The maintenance staff presses the destination call button 12 corresponding to the maintenance target car according to the relationship shown in FIG. When the dispatching car registration unit 19 of the own car detects the press (step S53), the name of the car related to the pressed destination call button 12 is selected as the selected car based on the information shown in FIG. And the pressed destination call button 12 is turned on (step S54).

  In this car information registration process, it is necessary to further operate the destination call button 12 to select floor information. Therefore, the number of destination call buttons 12 that can be operated for selecting the number machine is single.

When it is determined that there is no selection mistake (YES in step S55), the maintenance staff presses the door open button in the car 3. When the car dispatching car registration unit 19 of the own car detects the pressing (step S56), the information of the selected car held in the internal memory as described above is registered in the internal memory as car information of car information.
When the car assignment car registration unit 19 performs the car information registration process, it turns off the destination call button 12 that was turned on in step S54 (step S57).

  Here, the floor information can be continuously registered. The dispatch car registration unit 19 holds information indicating the relationship between the floor to be dispatched of the maintenance target car and the destination call button 12.

  The maintenance staff grasps the information indicating the relationship, and presses the destination call button 12 corresponding to the floor where the maintenance target car is dispatched among B1F to 10F. The number of destination call buttons 12 that can be operated by maintenance personnel for designating the floor is single.

When the dispatched car registration unit 19 of the car control unit 11 of the own machine detects the press (step S58), the destination car that has been pressed is determined based on the information indicating the relation between the destination call button 12 and the floor. The floor associated with the call button 12 is held in the internal memory as the selected floor, and the pressed destination call button 12 is turned on (step S59).
As a result, the maintenance staff can visually recognize that the floor to be dispatched of the maintenance target car has been selected.

  When it is determined that there is no selection mistake (YES in step S60), the maintenance staff presses the door open button in the car 3. When the car dispatching car registration unit 19 of the own machine detects the pressing (step S61), the information on the selected floor held in the internal memory is registered in the internal memory as the floor information of the car information (step S62).

  When the car allocation register 19 performs the car information registration process, the car dispatching car registration unit 19 turns off the door opening button that is lit in the process of step S52 and the destination call button 12 that is lit in the process of step S59 (step S63).

  When the maintenance staff determines that there is an error in the registered car information such as the car information and the floor information after the floor information is registered, that is, after the lit door open button is turned off, In step S64, the door closing button is pressed while the door opening / closing button 13 of the car operating panel 4 is being pressed (step S64 → S51).

  When the dispatched car registration unit 19 detects the press, the car allocation car 19 deletes the car information registered in the process of step S57 and the floor information that is the car information registered in the process of step S62, and then performs the process of step S52. Migrate to

  The maintenance staff also determined that there was an error in the operation of the destination call button 12 for selecting the maintenance target machine or floor before the registration of the floor information was completed, that is, the door open button was lit. If the user wants to cancel the selection (NO in step S55, NO in step S60), the door close button is pressed.

  When the dispatching car registration unit 19 detects pressing of the door closing button (step S65), the door opening button lit in the process of step S52 and the destination call button 12 lit in the process of step S54 or the process of step S59 are turned off. Let Furthermore, the dispatched car registration unit 19 deletes the information on the selected or registered car and the information on the selected floor, and cancels the mode in which car information can be registered (step S66).

The above is the details of the car information registration process. Next, the process until the car 3 responds to the elevator maintenance staff after the car information is registered will be described with reference to FIG.
When the group management control unit 14 inputs the car information output from the dispatched car registration unit 19 (YES in step S7), the dispatched car control unit 20 excludes the car indicated by the car information from the assignment target of the hall call. Is output to the group management separation control unit 18 (step S8).
The group management separation control unit 18 excludes the car indicated by the car information from the dispatch car registration part 19, that is, the maintenance target car from the assignment target of the new hall call.

  If there is already a hall call assignment or destination call registration for the maintenance target car (YES in step S9), the dispatch car control unit 20 responds to all calls (step S10), and the final destination call. When the door is opened after a response to registration (YES in step S11), a vehicle dispatch command is output to the car control unit 11 of the car to be maintained, that is, the car information of the car information (step S12).

  Further, the car control unit 11 of the maintenance target car has a landing call assignment or a destination call registration for the maintenance target car, and at the timing when the car 3 opens in response to the final destination call, the landing 6 In order to prevent new elevator users from getting on the car 3, an announcement to the effect that it is a maintenance target is output from the car 3 or the speaker at the hall 6 to turn off the car lighting. In this way, it is possible to limit the passenger ride and further improve convenience.

  On the other hand, if there is no hall call assignment or destination call registration for the maintenance target car (NO in step S9), the dispatch car control unit 20 maintains a dispatch command to the floor indicated by the floor information of the car information. It outputs to the car control part 11 of a target number machine (step S9-> S12).

  The dispatching command from the dispatching car control unit 20 includes floor information for making the maintenance target car respond, that is, floor information in the car information. The car controller 11 that is the output destination of the dispatch command causes the car 3 to travel to the floor indicated by the floor information of the dispatch command (step S13).

  In addition, when the car 3 responds to the floor indicated by the floor information, the car control unit 11 sets the lantern 16 corresponding to the own car at the landing 6 so that it can be visually recognized that the car has responded by the dispatch command. Flashes (step S14).

  The car control unit 11 maintains the door open state until the car operating panel 4 or the maintenance mode changeover switch 17 is operated or a certain time elapses from the response for the car 3 responding to the dispatch command (Step S1). S15).

  The car control unit 11 operates the in-car operation panel 4 (YES in step S16), operates the maintenance mode changeover switch 17 (YES in step S17), or when a certain time has elapsed from the response (step S18). YES), the door-open state holding is canceled (step S19), and a release command for canceling allocation of the landing call of the own machine is output to the group management disconnection control unit 18 of the group management control unit 14.

  The group management disconnection control unit 18 cancels the exclusion of the maintenance target car from the landing call set in the process of step S8 in accordance with the cancellation command from the car control unit 11 (step S20). As a result, the maintenance target machine returns to normal operation (step S21).

  As described above, in the elevator according to the embodiment of the present invention, the maintenance mode changeover switch 7 in the maintenance box 5 in the middle car BOX 5 among the cars that perform group management control and the various buttons on the operation panel 4 in the car 4 By performing a predetermined operation, it is possible to specify the number of the maintenance target unit and the response floor of the unit.

  Therefore, it is not necessary to add a new device for the maintenance personnel to select the maintenance target machine. As a result, the maintenance staff can secure a passenger car to be maintained while preventing a decrease in maintenance efficiency and a decrease in service to customers.

  Further, in this elevator, the car 3 to be maintained is specified by performing a predetermined operation on the destination call button or door opening / closing button in an arbitrary car, and then the car is uniquely determined. Therefore, the button operation for designating the response floor of the car 3 to be maintained can be omitted.

  In addition, the car allocating control unit 20 of the group management control unit 14 receives car information from the car allocating car registration unit 19, and if there is already a destination call registration or hall call assignment in the car 3 that outputs the car allocation command. After answering all calls, the dispatching command for dispatching the car 3 is output to the car control unit 11, so that all the passengers in the car 3 get off and the designated car 3 is the maintenance staff. Respond to the floor where there is. Therefore, it is possible to avoid passengers' discomfort due to passengers and maintenance personnel getting on.

  Further, the car control unit 11 of the maintenance target car assigns the door open state and the hall call until a certain time elapses after the response of the car 3 to the floor specified by the dispatch command from the dispatch car control unit 20. By maintaining the exclusion from the target, it is possible to secure time until the maintenance staff moves to the response machine. In addition, even when the maintenance staff mistakenly performs an operation for registering the car information, an effect of automatically returning to normal operation after a predetermined time has been obtained.

  In addition, the car control unit 11 of the maintenance target car keeps the door open until the destination call button or the door open / close button is operated after responding to the floor specified by the dispatch command from the dispatch car control unit 20. Thus, it is possible to limit the departure of the response machine until the maintenance staff moves to the response machine.

  In addition, when the car control unit 11 of the maintenance target car receives a dispatch command from the dispatch car control unit 20, an announcement is made so that general passengers do not get on the car when responding to the final destination call, and the dispatch command is issued. By preventing the passenger from getting on the receiving car, the car 3 can respond to the floor where the maintenance staff is present as soon as possible.

  In addition, when the car control unit 11 of the maintenance target car receives a dispatch command from the dispatch car control unit 20, the car lighting is turned off when responding to the final destination call, and the car receiving the dispatch command is used by the customer. It is possible to make the car 3 respond as quickly as possible to the floor where the maintenance staff is present by preventing the new boarding.

  In the above-described embodiment, if there is a hall call assignment for the maintenance target car as a result of the process of step S9, the dispatch car control part 20 of the group management control part 14 determines the assignment to the other car 3. Changes may be made. By performing such processing, it becomes possible to make the designated car 3 respond to the floor where the maintenance staff is present as soon as possible. In changing the assignment when there are three or more cars 3, the car that operated the destination call button 12 for registering car information may be excluded from the assignment change target.

  Further, in the above-described embodiment, the car allocating car control unit 20 is described as outputting a car dispatch command after responding to all registered calls. However, the present invention is not limited to this. For example, steps S9 to S11 are performed. Without processing, the dispatch command is output simultaneously with the exclusion from the assignment target in step S8, and the car 3 to be maintained is made to respond in a state where normal landing call, destination call and dispatch command are mixed. Also good.

  Further, in the maintenance mode, it has been described that the door closing button is operated while pressing the door opening button so that the car information can be registered. However, the present invention is not limited to this, and the specific first button of the destination call button You may substitute by operation of a 2nd button.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be omitted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
