Background technique

In the past, when an elevator maintenance worker wanted to secure a car to be repaired by calling and registering an elevator in the elevator hall in order to perform car maintenance, the elevator in the group management did not know which car responded, so sometimes it was not the car to be repaired. number machine to respond. At this time, it is necessary to register the call of the elevator in the elevator hall again, which has the possibility of reducing maintenance efficiency and service to customers.

In order to improve this problem, for example, as disclosed in JP-A-7-10399, a car to be maintained is designated by operating a hall elevator call button provided in a hall differently than usual. In addition, as disclosed in Japanese Unexamined Patent Application Publication No. 9-156842, an arrival car specifying device is additionally provided in the elevator hall, and the car designated as the maintenance object is designated by the arriving car specifying device, so that the car is opposite to where the elevator maintenance personnel are located. floor to respond.

However, in the method of specifying the car to be maintained by operating the elevator calling button in the hall as described above, only one of the uppermost floor and the lowermost floor is provided with an operation button in the uppermost floor button and the lowermost floor button, so it is difficult to perform maintenance. Even if a car is designated by an operation different from the usual one, it cannot be judged whether it has been registered or not.

In addition, when the arrival car specifying device is installed in the hall as described above, it is necessary to separately install equipment for operation in the hall, so it is considered that there is a bad influence on the cost and the appearance of the hall.

Contents of the invention

Therefore, an object of the present invention is to provide an elevator capable of securing maintenance-targeted cars among group-management-controlled cars without requiring additional operating equipment and without causing a drop in maintenance efficiency and service to customers.

That is, the elevator related to the present invention is characterized in that: according to the operation of the elevator call button for the destination floor of any one of the plurality of cars, wherein the plurality of cars are raised and lowered according to the group management control, corresponding to the operated The car that is different from the car set by the elevator call button of the destination floor is registered, so that the registered car responds to the predetermined floor.

Fig. 2 is a flowchart showing an example (Part 1) of processing related to the response of the elevator maintenance target car in the embodiment of the present invention.

In FIG. 2 , the process from registration of the car information of the maintenance target car by an elevator maintenance worker to output of the registered information to the group supervisory control unit 14 will be described.

Fig. 3 is a flowchart showing an example (No. 2) of processing related to the response of the maintenance-target car of the elevator in the embodiment of the present invention.

In FIG. 3 , the flow until the car 3 of the maintenance target car responds to the elevator maintenance personnel with respect to the registered car information will be described.

First, the maintenance mode changeover switch 17 is in an OFF state in an initial state. In order to register the car information, an elevator maintenance worker gets on an arbitrary car 3 and switches the maintenance mode switching switch 17 to an on state.

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

When a signal from the maintenance mode changeover switch 17 is input, the group management disconnection control unit 18 determines that the operation mode of the car indicated by the input signal has changed to the maintenance mode (Yes in step S1), and the car is removed from the boarding mode. Removed from the allocation object for the hall elevator call. In addition, when switching to the maintenance mode is not performed, the registration process of the car information after that is not performed (No in step S1).

According to the operation of the destination floor elevator call button 12 and the door switch button 13 carried out by the maintenance personnel, the registration of the car information of the number machine different from the number machine carried out by the allocation car registration part 19 is carried out (step S2), wherein This allocating car registration part 19 is the allocating car registering part of the car control part 11 of the installed car control part 11 of the maintenance mode switch 17 operated as mentioned above, when the maintenance mode switch 17 returns to the cut-off state (step S3), the allocated car registration unit 19 determines that there is car information (step S4).

When car information is registered in the car registration section 19 (step S4 is yes), the information of this number machine is combined with the information of the set number machine of the operated maintenance mode switching switch 17 of this number machine, and sent to the group management control. Section 14 outputs (step S5).

Then, the group management cut-off control unit 18 of the group management control unit 14 removes the operation of removing the number machine from the allocation target of the hall elevator call, which is set with respect to the number machine indicated by the information of the set number machine. Release, wherein the information of the set car comes from the allocation car registration unit 19, and this car is judged as the car whose maintenance mode is to be released, and it returns to normal operation (step S6).

In addition, when the allocating car registration unit 19 determines that the result of the processing in step S4 is that the car information is not registered, that is, the registration of the car information by the processing in step S2 is not performed, the maintenance mode switching switch 17 is returned to the off state ( No in step S4), a signal indicating the machine name of the own machine is output to the group supervisory control unit 14. After this process, it goes to the process of step S6.

Here, the details of the registration process of the car information which is the process of step S2 are demonstrated.

Regarding the registration method of the car information, there are a method of registering only the car information of the maintenance-targeted car and a method of separately registering the car information of the maintenance-targeted car and the floor information.

First, as a first example, a method of registering only the machine number information of the maintenance target machine will be described with reference to FIG. 4 . Fig. 4 is a flowchart showing a first example of car information registration processing of a maintenance-target car of an elevator in the embodiment of the present invention.

When the elevator maintainer presses the door-opening button of the door switch button 13 of the operating panel 4 in the car and simultaneously presses the door-closing button, the allocation car registration part 19 of the car control part 11 of the car of this number machine detects the pressing operation ( Step S31), wherein the operation panel 4 in the car is the operation panel in the car of the set number car of the maintenance mode switching switch 17 that is switched to the on state as described above, and the car registration unit 19 is allocated according to the car operation panel. The operation mode of the inner operation panel 4 is set to a mode enabling registration of car information, and the operated door opening button is lit (step S32). Thereby, the maintenance worker can visually recognize that the car information of the car to be maintained can be registered.

5 is a diagram showing a relationship between a destination floor elevator call button of an elevator car and a machine number designated as a maintenance target when the button is operated in the embodiment of the present invention.

The assigned car registration unit 19 of each car holds information indicating the association between the destination floor elevator call button 12 and the car name shown in FIG. 5 . However, the assigned car registration unit 19 of each car separately holds information that the association between the own car and the elevator call button 12 of the destination floor is invalid among the associations shown in FIG. 5 .

The maintenance worker grasps the information indicating this association, and presses the destination floor elevator call button 12 corresponding to the maintenance target car different from the number car the maintenance worker is on. The allocation car registration part 19 of the car control part 11 of the car control part 11 of the set number machine of the pressed destination floor elevator call button 12 detects the pressing operation (step S33), based on the indication purpose shown in Fig. 5 The associated information of the floor elevator call button 12 and the number machine name, the number machine name associated with the pressed destination floor elevator call button 12 is kept in the internal memory as the selected number machine of the maintenance object, and the The pressed destination floor elevator call button 12 lights up (step S34). Thereby, the maintenance worker can visually recognize that the maintenance target number machine has been selected.

In addition, the number of cars that can be simultaneously selected as a maintenance target car may be singular or plural. When a maintenance worker selects a plurality of machines to be maintained, he only needs to press the destination floor elevator calling button 12 corresponding to each machine.

When the maintenance person judges that there is no selection error (Yes in step S35), he presses the door-opening button in the car 3 . When the assigned car registration unit 19 of the own car detects the pressing operation (step S36), it performs registration processing of the car information in the internal memory (step S37).

The car information mentioned here is car number information and floor information. The car information is information indicating the selected car of the maintenance car held in the process of step S34. In addition, the floor information is uniquely identified as information indicating the floor where the car 3 that has performed the operation for the car information currently stops. In addition, the floor information may be fixed information called the uppermost floor and the lowermost floor.

The allocated car registration unit 19 turns off the door open button lit in the process of step S32 and the destination floor elevator call button 12 lit in the process of step S34 after performing the car information registration process (step S38).

After the registration of the car information, after the door-opening button that is lighted is extinguished, the maintainer is judged to have an error in the content of the registration (no in step S39), and presses the button of the door switch button 13 of the operating panel 4 in the car. Press the door-closing button simultaneously with the door-opening button (step S39→S31). When the assigned car registration unit 19 detects the pressing operation, it deletes the car information registered in the process of step S37. After the erasure of the car information, go to the processing of step S32.

In addition, when the maintenance worker is in the state where the door-opening button is on before the registration is completed, when it is judged that the operation of the destination floor elevator call button 12 for the selection of the maintenance target car is wrong or when the selection is intended to be canceled (step S35 No), press the door close button.

Allocating the car registration section 19 when detecting the pressing of the door closing button (step S40), the door opening button lighted in the processing of step S32 and the destination floor elevator call button 12 lighted in the processing of step S34 are extinguished, The held information of the selected car is deleted, and the mode in which the car information of the own car can be registered is released (step S41).

Next, as a second example of the registration method of car information, a method of separately registering car number information and floor information of a maintenance target will be described with reference to FIG. 6 . 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.

When the elevator maintainer presses the door-opening button of the door switch button 13 of the operating panel 4 in the car and simultaneously presses the door-closing button, the allocation car registration part 19 of the car of this number detects the pressing operation (step S51), wherein The operation panel 4 in the car is the operation panel in the car of the installed car of the maintenance mode switching switch 17 that is switched to the ON state as described above, and the allocation car registration unit 19 will The operation mode is set to a mode in which car information can be registered, and the operated door opening button is lit (step S52).

According to the relationship shown in Fig. 5, the maintenance worker presses the elevator calling button 12 of the destination floor corresponding to the maintenance target machine. When the allocation car registration unit 19 of the own machine detects the pressing operation (step S53), based on the information shown in FIG. It is held in the internal memory as the selected car, and at the same time, the pressed destination floor elevator call button 12 is lit (step S54).

In this car information registration process, in order to select floor information, it is necessary to further operate the destination floor elevator call button 12 . Therefore, the number of objects of the operable destination floor elevator call button 12 for the selection of the car is an odd number.

When the maintenance person judges that there is no selection error (Yes in step S55), he presses the door-opening button in the car 3 . When the allocated car registration unit 19 of the own car detects the pressing operation (step S56), it registers the information of the selected car stored in the internal memory as the car information of the car information in the same manner as above. in memory.

The allocated car registration unit 19 turns off the destination floor elevator call button 12 that was lit in the process of step S54 after performing the process of registering the number car information of the car information (step S57).

Here, next, it becomes a state where floor information can be registered. The allocation car registration unit 19 holds information indicating the association between the allocation target floor of the maintenance target car and the elevator call button 12 of the destination floor.

The maintenance worker grasps the information indicating this association, and presses the destination floor elevator call button 12 corresponding to the floor to which the maintenance target car is dispatched among B1F to 10F. The number of objects of the destination floor elevator call buttons 12 that can be operated by the maintenance personnel for designation of the floor is an odd number.

When the dispatching car registration part 19 of the car control part 11 of this number machine detects this pressing operation (step S58), based on the information of the association between the elevator call button 12 and the floor of the expression destination floor, the corresponding The floor associated with the pressed destination floor elevator call button 12 is held in the internal memory as a selected floor, and the pressed destination floor elevator call button 12 is illuminated (step S59).

Thereby, the maintenance worker can visually recognize the allocation target floor of which the maintenance target number machine has been selected.

When the maintenance worker judges that there is no wrong selection (Yes in step S60), he presses the door-opening button in the car 3 . When the allocation car registration part 19 of the own number car detects this pressing operation (step S61), the information of the selected floor kept in the internal memory is registered in the internal memory as the floor information of the car information (step S62) .

After the registration process of the car information, the allocation car registration unit 19 turns off the door open button lit in the process of step S52 and the destination floor elevator call button 12 lit in the process of step S59 (step S63).

After the registration of the floor information, after the door-opening button that is lighted is extinguished, the maintenance personnel will press the button when it is judged as the number car information and the floor information of the registered car information that there is an error (no in step S64) as described above. The door-opening button of the door switch button 13 of the operating panel 4 in the lower car presses the door-closing button simultaneously (step S64→S51).

When the allocation car registration section 19 detects the pressing operation, the number car information registered as the car information in the process of step S57 and the floor information registered as the car information in the process of step S62 are deleted, Then go to the process of step S52.

In addition, when the maintenance worker judges that the operation of the destination floor elevator call button 12 for selection of the maintenance target car and floor is wrong or wants to cancel the operation of the door open button before the registration of the floor information is completed, the door open button is lit. When selecting (No in step S55, No in step S60), press the door close button.

When the car registration section 19 detects that the door-closing button is pressed (step S65), the door-opening button lighted in the process of step S52 and the destination floor elevator lighted in the process of step S54 and the process of step S59 are The call button 12 goes out. Furthermore, the assigned car registration unit 19 deletes the selected or registered car number information and the information of the selected floor, and also cancels the mode in which the car information can be registered (step S66).

The above is the details of the car information registration process. Next, the process from the registration of the car information to the response of the car 3 to the elevator maintenance personnel will be described with reference to FIG. 3 .

When the group management control unit 14 inputs the car information output from the allocated car registration unit 19 (Yes in step S7), the allocated car control unit 20 outputs to the group management cut-off control unit 18 for indicating the car information. The instruction to remove the No. car from the allocation object called by the hall elevator (step S8).

The group management cut-off control unit 18 removes the car indicated by the car information from the allocated car registration unit 19, that is, the car to be maintained, from the allocation targets of new hall elevator calls.

When allocating the car control unit 20 with the elevator hall elevator call allocation related to the maintenance object number machine or the destination floor elevator call registration has been completed (step S9 is yes), this number machine responds to all elevator calls (step S10), in When the door is opened in response to the call registration of the final destination floor elevator (yes in step S11), the car control section 11 of the number machine indicated by the number machine information of the car information to the maintenance object number machine outputs an allocation command (step S12) .

In addition, when the car control unit 11 of the maintenance target car has completed the allocation of hall elevator calls or the registration of destination floor elevator calls related to the maintenance target car, when the car 3 responds to the final destination floor elevator call and opens the door Timing, in order to make no new elevator users in the elevator hall 6 take the car 3, the loudspeaker output of the elevator hall 6 in the car 3 indicates that the car is the broadcast of the maintenance object, and the car in the car The lighting is off. In this way, it is possible to limit the user's riding, and further improve the convenience.

On the other hand, when there is no hall elevator call allocation or destination floor elevator call registration related to the maintenance target car (No in step S9), the dispatching car control unit 20 sends a report to the car control unit 11 of the maintenance target car. An allocation command for allocation to the floor indicated by the floor information of the car information is output (step S9→S12).

The dispatch command from the dispatch car control unit 20 includes the floor information to which the car to be maintained responds, that is, the floor information in the car information. The output destination car control unit 11 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 blinks the indicator light 16 corresponding to the own car of the hall 6 in order to visually recognize the response by the allocation command ( Step S14).

The car control unit 11 operates the car operating panel 4 and the maintenance mode changeover switch 17 for the car 3 that responds to the deployment command, or keeps the door open until a certain time elapses from the response (step S15).

When the car control unit 11 operates the operating panel 4 in the car (yes of step S16), operates the maintenance mode switch 17 (yes of step S17), or passes through a certain period of time from the response (yes of step S18), the door will be kept open. The state operation is released (step S19), and a release command is output to the group management cut-off control unit 18 of the group management control unit 14 to cancel the operation of removing the own car from the allocation object of hall elevator calls.

Group management cuts off the control section 18 according to the release command from the car control section 11, cancels the operation set in the process of step S8 that the maintenance object number car is removed from the distribution object of the hall elevator call (step S20 ). Thereby, the machine to be maintained returns to normal operation (step S21).

As described above, in the elevator in the embodiment of the present invention, the maintenance mode selector switch 7 in the maintenance box 5 in the maintenance box 5 in any car 3 in each number car that performs group supervisory control and the operation panel in the car The various buttons of 4 can be operated in advance, whereby the car of the car to be maintained and the corresponding floor of the car can be designated.

Therefore, there is no need to add additional equipment for the maintenance worker to select the machine to be maintained. Thereby, the maintenance worker can secure the maintenance-targeted car while preventing a decrease in maintenance efficiency and a decrease in service to customers.

In addition, in this elevator, when the designation of the maintenance target car 3 is performed by performing a predetermined operation on the destination floor elevator call button or the door switch button in an arbitrary car, the car 3 can be uniquely paired. Since the specified floor responds, the button operation for specifying the response floor of the car 3 to be maintained can be omitted.

In addition, the dispatching car control part 20 of the group management control part 14 receives the car information from the dispatching car registration part 19, and the car 3 that outputs the dispatching command has already registered the elevator call of the destination floor or the elevator call of the hall. When allocating the elevator, respond to all elevator calls, and then output to the car control unit 11 an allocation command for allocating the car 3, so that the designated car 3 is after all the passengers in the car 3 get off the elevator Respond to the floor where the maintenance man is. Therefore, it is possible to avoid passenger's discomfort caused by the passenger and the maintenance worker getting on the elevator at the same time.

In addition, the car control unit 11 of the car to be maintained keeps the door open and the car 3 in the open state until a certain time elapses after the car 3 responds to the floor designated by the dispatch command from the dispatch car control unit 20 . Removal of the allocation object called from the hall elevator ensures time until the maintenance worker moves to the responding car. In addition, even if a maintenance worker performs an operation for registering car information by mistake, normal operation is automatically restored after a certain period of time has elapsed.

In addition, after the car control unit 11 of the car to be maintained responds to the floor designated by the dispatch command from the dispatch car control unit 20, the door is kept open until the elevator call button or the door switch button of the destination floor is operated. , thereby being able to limit the departure of the response machine until the maintenance personnel move to the response machine.

In addition, when the car control unit 11 of the car to be maintained receives the dispatch command from the dispatch car control unit 20 and responds to the elevator call of the final destination floor, in order to prevent ordinary users from taking the car 3 , to broadcast to prevent the user from taking the car that has received the deployment command, thereby enabling the car 3 to respond to the floor where the maintenance worker is located as soon as possible.

In addition, when the car control unit 11 of the car to be maintained receives the allocation command from the allocation car control unit 20, when responding to the call of the elevator at the final destination floor, the lighting in the car is turned off to prevent new use. The operator rides on the car that has received the deployment command, thereby enabling the car 3 to respond to the floor where the maintenance worker is located as soon as possible.

In the above-mentioned embodiment, when the dispatching car control unit 20 of the group management control unit 14 finds that there is a hall elevator call allocation related to the maintenance target car as a result of the processing in step S9, the allocation can also be made to other elevators. Change of car 3. When such processing is performed, the designated car 3 can be made to respond to the floor where the maintenance worker is present as quickly as possible. When changing the allocation when there are three or more cars 3, the car on which the destination floor elevator call button 12 for registration of the car information has been operated may be excluded from the change object of the allocation.

In addition, in the above-mentioned embodiment, it has been described that the dispatching car control unit 20 responds to all the registered elevator calls and then outputs the dispatching command, but it is not limited to this, and steps S9 to S11, for example, may not be performed. In the process of step S8, that is, to remove from the allocation target and simultaneously output the allocation command, the maintenance target car 3 is made to respond in a state where the normal hall elevator call, the destination floor elevator call, and the allocation command are mixed.

In addition, the operation of pressing the door-close button while pressing the door-open button in order to make it possible to register the car information in the maintenance mode has been described, but it is not limited thereto. 1 button and 2 button operation instead.
