Abstract

PROBLEM TO BE SOLVED: To secure a smooth operation by causing landing call registration to be canceled in an unnecessary situation where a user is not present, even when buttons in the same direction are depressed in a landing button for a single-operation elevator and a landing button for a group-management operation elevator at the same floor.SOLUTION: A user detection means 10 installed in each floor of a building and detecting the presence of a user at a landing is provided. When a landing button 4 for a single-operation elevator and a landing button 5 for a group-management operation elevator on the same floor are depressed and when the depressed buttons are in the same direction, the user detection means 10 is started, and it is determined whether or not the user gets on a car arriving at the landing first. Further, when it is determined that the user has left the landing after the car has moved, the landing call registration of the elevator in which the registration remains is canceled.

Description

  Embodiments of the present invention relate to an elevator control device having a single operation elevator and a group management operation elevator landing button on the same floor.

  In the building where the elevator is installed, the elevator platform on each floor is provided with a platform button for calling a car. When this landing button is pressed, the elevator control device performs landing call registration and stops the car on the registered floor. Even if the hall button of the elevator hall is accidentally pressed or tampered with, the car will stop even though it is not necessary for that hall.

  Also in the conventional elevator system, if the hall call registration is made once and the operation of the hall button satisfies a certain condition, it is determined that the operation is a mischief and the hall call registration is canceled. Some have a function (for example, Patent Document 1).

JP 2002-348054 A

  In a building where a plurality of elevators are operated, a user who wants to get on the elevator car quickly pushes all the landing buttons on the same floor and gets into the car that has arrived first. In that case, if each elevator is in group management operation, the landing call registration will not remain after the user has entered the car, so there will be no trouble in operation.

  However, depending on the building, an elevator for single operation for personnel cargo and an elevator for group management operation may be provided. In that case, a hall button for a single operation elevator and a hall button for a group management operation elevator coexist on the same floor.

  In a situation where a user who wants to get into the elevator car as soon as possible has pushed the button in the same direction with the landing button on the same floor, even after the user gets in the car that arrived first, Of the group management operation elevators, one hall call registration remains valid. Under this circumstance, another car will stop at this floor even though there are no users. From the viewpoint of a user who is already in the stopped car, the user feels that the service has been delayed because the user does not get in.

  In addition, the same operation delay problem occurs when a landing button on the same floor is pressed due to mischief.

  Therefore, an object of the present invention is to solve the above-mentioned problems, and even when a button in the same direction is pressed by a hall button for a single operation elevator and a hall button for a group management operation elevator on the same floor, the user can It is an object of the present invention to provide an elevator control device that can ensure smooth operation by canceling the hall call registration in a situation that is not necessary as in the case where the vehicle does not exist.

  In order to achieve the above object, according to the present invention, a building is provided with a single operation elevator and a group management operation elevator, and each floor of the building has a landing button for the single operation elevator and the group management. In an elevator control device in which a landing button for an elevator for driving is installed, a user detecting means that is installed on each floor of the building and detects the presence or absence of a user at the landing, and the single operation on the same floor When the elevator hall button for the elevator and the elevator hall button for the group management operation are pressed and the button is pressed in the same direction, the user detection means is activated and the elevator If it is determined whether or not the user has entered the car that has arrived at, and if it is determined that there are no more users at the boarding place after the car has moved, the registration will remain. , And the landing call registration canceling means for canceling the hall call registration of the elevator has is characterized in that it comprises a.

Embodiments of an elevator control apparatus according to the present invention will be described below with reference to the accompanying drawings.
First embodiment
FIG. 1 is a diagram showing an elevator hall to which an elevator control apparatus according to a first embodiment of the present invention is applied.
The building has a total of four elevators from Unit 1 to Unit 4. Unit 1 is a single-operated elevator, and Units 2, 3, and 4 are elevators that are operated in groups. The elevator hall is assumed to be provided on each floor from the first floor to the fifth floor, for the sake of simplicity.

In FIG. 1, reference numeral 2 is a No. 1 controller that controls the operation of an independently operated No. 1 elevator. Reference numeral 3 is a group management control device that manages the group management operation of the second machine, the third machine, and the fourth machine.
On each floor floor, there is a hall button 4 that calls the car of the first car that is an elevator operating alone, and a hall that calls one of the cars of the second, third, and fourth cars that are elevators for group management operation. Button 5 is installed. The landing buttons 5 are provided at two places between the second and third machines and between the third and fourth machines. The landing buttons 4 and 5 are respectively provided with an up button and a down button. When the hall button 4 is operated, a hall call is registered in the No. 1 controller 2 and the car of No. 1 arrives at the hall. On the other hand, when the hall button 5 is operated, the hall call is registered in the group management control device 3, and the group management control device 3 selects the optimum machine from the No. 2, No. 3, and No. 4 machines. It is supposed to be directed to.

A monitoring camera 10 used as means for detecting the presence or absence of a user at the landing is installed at the landing on each floor. The video data of the monitoring camera 10 is transmitted to a computer constituting the hall call registration cancellation unit 8. In addition, the hall call registration cancellation unit 8 is connected to hall buttons 4 and 5 on each floor via communication lines 11 and 12.
The hall call deregistration unit 8 has a function of performing image processing such as binarization on the video data transmitted from the surveillance camera 10 to determine the presence or absence of a user, and operates according to the flowchart of FIG. It has the function of canceling the hall call.

  Next, the processing content of the hall call registration cancellation unit 8 will be described with reference to the flowchart of FIG.

  First, in FIG. 1, for example, it is assumed that a user at a landing on the third floor is going to get down to the first floor. In order to get on the car as soon as possible, the user not only presses the lowering button of the landing button 4 that calls the first machine that is the elevator of the single operation, but also the elevators of the second and third machines that are the elevators of the group management operation. Assume that the descent button is pressed for the landing buttons 5 and 5 for group management operation that call any one of the cars of No. 4.

  When the user operates the landing buttons 4 and 5 (yes in step S10), the signals from the landing buttons 4 and 5 are the first unit control device 2 that controls the operation of the first unit in the single operation, and the group management operation. Are transmitted to the group management control device 3 for controlling No. 2 to No. 4 and landing call registration is performed (step S11).

  In addition, signals from the landing buttons 4 and 5 in the third floor hall are also transmitted to the hall call registration cancellation unit 8. The hall call registration cancellation unit 8 determines from the received signal from the hall button whether or not it is a hall button in the same direction (step S12).

  Since both of the landing buttons 4 and 5 were pressed at the landing on the third floor (yes in step S12), the process proceeds to the subsequent step S13, and the landing call deregistration unit 8 is installed in the third floor landing. The monitored surveillance camera 10 is activated (step S13). Thereafter, video data from the monitoring camera 10 is transmitted to the hall call deregistration unit 8, and by processing this video data, the hall call deregistration unit 8 detects that there is a user at the hall on the third floor. can do.

  Thereafter, the group management control device 3 responds to the hall call, for example, assigns No. 2 among No. 2, No. 3, No. 4, and No. 2, and the car of No. 2 quickly enters the 3rd floor hall where the user waits. Suppose you arrive.

  During this time, at the hall on the third floor, monitoring by the monitoring camera 10 continues, and it is detected that the user has entered the car that has arrived (yes in step S14). After all the users who were on the 3rd floor boarding boarded the second car, the second car will move toward the first floor.

  On the other hand, at this point, the elevator call registration on the third floor is still valid for the first-operated elevator for the first operation, so the elevator car for the first elevator will arrive on the third floor following the second one. ing. Therefore, even if the first car arrives, there is a possibility that no one gets in.

  Therefore, in step S15, the hall call deregistration unit 8 determines whether there is no user at the hall on the third floor based on the video data from the monitoring camera 10.

  When it is determined that all the users have entered the car of the preceding Unit 2 and no one is left (Yes in Step S15), the process proceeds to Step 16, and the hall call deregistration unit 8 performs the independent operation. The hall call registration registered in the control device 2 of the first elevator is cancelled.

  As described above, the registration of the 3rd floor hall call is canceled in the subsequent elevator of Unit 1 so that it will not stop at the 3rd floor hall even if there are no users. When a passenger is on the bus, the inconvenience that the operation is delayed can be surely prevented.

Second embodiment
Next, FIG. 3 is a flowchart showing a processing procedure for canceling the hall call registration of the control device according to the second embodiment of the present invention.

  This second embodiment is an embodiment characterized in that processing corresponding to a situation in which a user who presses the landing button leaves the landing without waiting for the arrival of the car as it is is performed.

  First, in FIG. 1, for example, it is assumed that a user at a landing on the third floor is going to get down to the first floor. In order to get on the car as soon as possible, the user not only presses the lowering button of the landing button 4 that calls the first machine that is the elevator of the single operation, but also the elevators of the second and third machines that are the elevators of the group management operation. It is assumed that the descent button is also pressed for the hall button 5 for group management operation that calls any one of the cars of Unit 4.

  By the operation of such a landing button by the user (yes in step S20), the first unit control device 2 that controls the operation of the first unit of the single operation, and the group management control device that controls the second unit to the fourth unit of the group management operation 3, the hall call registration is performed (step S21).

  In addition, signals from the landing buttons 4 and 5 in the third floor hall are also transmitted to the hall call registration cancellation unit 8. The hall call registration cancellation unit 8 determines from the received signal from the hall button whether or not it is a hall button in the same direction (step S22).

  In the hall on the third floor, since both the hall buttons 4 and 5 are pressed down (yes in step S22), the process proceeds to the next step S23, and the hall call deregistration unit 8 is installed in the hall on the third floor. The monitored surveillance camera 10 is activated (step S23). Thereafter, video data from the monitoring camera 10 is transmitted to the hall call deregistration unit 8, and by processing this video data, the hall call deregistration unit 8 detects that there is a user at the hall on the third floor. can do.

  In this way, monitoring by the surveillance camera 10 continues at the 3rd floor hall, but the user waiting for the arrival of the car presses the hall buttons 4 and 5 for some reason, There is a possibility of leaving.

  Therefore, when it is detected that there is no user at the third-floor hall (step S24: yes), in the following step 25, use is made within a preset time, for example, 30 seconds, 1 minute. It is determined whether the person returns. When it is detected that the user has returned to the landing on the third floor (yes in step S25), the hall call registration is continued so that the returning user can use the elevator (step S26). Therefore, the user who has returned does not need to press the hall button 4 or the hall button 5 again to call the hall.

  During this time, the group management control device 3 responds to the hall call and, for example, assigns No. 2 among No. 2, No. 3, No. 4, and No. 2, and the No. 2 elevator is waiting for the user on the third floor. Suppose you arrive early.

  At the third floor hall, monitoring by the surveillance camera 10 continues, and it is detected that the user has entered the arrival car (yes in step S27). After that, the car of Unit 2 will move toward the first floor.

  On the other hand, at this point, the stand-up registration on the 3rd floor is still valid for the first-operated elevator of Unit 1, so the elevator car for the 1st elevator is scheduled to arrive on the 3rd floor following the 2nd floor. ing. Therefore, even if the first car arrives, there is a possibility that no one gets in.

  Therefore, in step S28, the hall call deregistration unit 8 determines whether there is no user at the hall on the third floor based on the video data from the surveillance camera 10.

  If it is determined that the user has entered the car of the preceding Unit 2 and no one has left (Yes in Step S28), the process proceeds to Step S29, where the landing call deregistration unit 8 The hall call registration registered in the elevator control device 2 is canceled.

  In this way, the registration of the 3rd floor hall call is canceled in the subsequent elevator of Unit 1, so that there will be no stoppage at the 3rd floor hall even if there are no users, and passengers get on the 1st car. In such a case, the inconvenience that the operation is delayed can be surely prevented.

  The above is the processing when the user returns to the landing immediately in step S25. However, when the user does not return to the landing, the following processing is performed.

  That is, if the user does not return to the landing (NO in step S25), the process proceeds to step S30, and the landing call deregistration unit 8 registers the landing call registered in the control device 2 of the first-unit elevator for single operation. All registrations and hall call registrations registered in the group management control unit 3 that manages Units 2 to 4 are canceled.

  As a result of all the hall call registration being canceled, even if the hall call registration is performed by the hall button operations 4 and 5 due to mischief or the like, it is not necessary to stop the elevator, so that the delay of the elevator operation can be surely prevented.

Third embodiment
Next, FIG. 4 is a flowchart showing a processing procedure for canceling the hall call registration of the control device according to the third embodiment of the present invention.

  In this third embodiment, the attendance time zone where the necessity of the hall call registration cancellation process of the first embodiment is high, for example, the time zone from 7 am to 10 am, and other time zones where the necessity is low In this embodiment, a normal elevator operation is performed without a hall call cancellation process.

  In FIG. 4, the elevator is normally operated early in the morning, during the daytime, and at night (step S32). This is because there are fewer elevator users in this time zone than in the work hours, so there is no problem in operation even if you do not cancel the registration of the hall call remaining in the hall where there is no user.

  Therefore, for example, when a time zone in which the number of attendees increases such as 7:00 am to 10:00 pm (yes in step S <b> 33), the hall call registration cancellation processing in steps S <b> 10 to S <b> 16 is performed. Become. Since the processing content of this hall call registration cancellation is the same as steps S10 to S16 shown in the flowchart of FIG. 2 of the first embodiment, the description thereof is omitted.

  When the attendance hours end (Yes in step S34), the operation is switched to the normal elevator operation without the hall call registration cancellation process (step S35).

  As described above, passengers are concentrated like time attendance hours, so there is no need to stop at the landing even when there is no user, so it is urgent. The elevator can be operated according to the needs of passengers who are traveling, and it is not necessary to activate the surveillance camera 10 every time the same direction of the landing button is pressed at the same landing at other times when passengers are not concentrated. Control can be saved.

  In this embodiment, the hall call registration cancellation performed in the working hours is performed according to the process shown in the flowchart of FIG. 2 of the first embodiment. You may make it implement the process of the content shown.

Fourth embodiment
Next, FIG. 5 shows a floor landing to which the fourth embodiment of the present invention is applied. FIG. 6 is a flowchart showing a hall call registration release processing procedure according to the fourth embodiment of the present invention.

  In the fourth embodiment, as shown in FIG. 6, in addition to the landing buttons 4 and 5, a voice guidance device 12 that guides the user at the landing by voice is installed at the landing on each floor. Yes.

  Hereinafter, the processing details of the hall call registration cancellation will be described with reference to FIG.

  First, in FIG. 5, for example, it is assumed that there is only one user at the hall on the third floor. In order to get on the car as soon as possible, the user not only presses the lowering button of the landing button 4 that calls the first machine that is the elevator of the single operation, but also the elevators of the second and third machines that are the elevators of the group management operation. It is assumed that the descent button is also pressed for the hall button 5 for group management operation that calls any one of the cars of Unit 4.

  By the operation of the landing buttons 4 and 5 by the user (yes in step S40), the first unit control device 2 that controls the operation of the first unit for single operation, the second group to the fourth unit for group management operation In the management control device 3, hall call registration is performed (step S41).

  In addition, signals from the landing buttons 4 and 5 in the third floor hall are also transmitted to the hall call registration cancellation unit 8. The hall call deregistration unit 8 determines from the received signals from the hall buttons 4 and 5 whether or not it is a hall button in the same direction (step S42).

  In the hall on the third floor, both of the pressed hall buttons 4 and 5 are descending buttons (yes in step S42), so the process proceeds to the subsequent step S43, and the hall call registration canceling unit 8 is installed in the hall on the third floor. The monitoring camera 10 is activated (step S43). Thereafter, video data from the monitoring camera 10 is transmitted to the hall call deregistration unit 8, and by processing this video data, the hall call deregistration unit 8 detects that there is a user at the hall on the third floor. can do.

  In this embodiment, the hall call deregistration unit 8 also determines how many users are (step S44). At this time, if it is determined that there is only one user, in the subsequent step S45, the voice guidance device 12 will guide the user to the contents that call attention. For example, if one person presses a plurality of landing buttons, the voice may be delayed such that the elevator operation may be delayed.

  Thereafter, in response to the hall call, for example, the group management control device 3 assigns No. 2 among the No. 2, No. 3, No. 4 and No. 2 cars, and the car of No. 2 is promptly placed at the 3rd floor hall where the user waits. Suppose you arrive.

  During this time, at the hall on the third floor, monitoring by the monitoring camera 10 continues, and it is detected that the user has entered the car that has arrived (yes in step S46). After all the users who were on the 3rd floor boarding boarded the second car, the second car will move toward the first floor.

  On the other hand, at this time, the stand-up registration on the third floor is still valid for the first-operated elevator for the first operation, so the elevator car for the first elevator will arrive on the third floor following the second one. ing. Therefore, even if the first car arrives, there will be no one getting in.

  Therefore, in step S47, the hall call registration cancellation unit 8 confirms whether there is no user at the hall on the third floor based on the video data from the surveillance camera 10.

  If it is determined that the user has entered the car of the preceding No. 2 car and no one has been left (yes in step S47), the process proceeds to step 48, where the hall call deregistration unit 8 performs the independent operation 1 The hall call registration registered in the control device 2 of the elevator is cancelled.

  As described above, the registration of the 3rd floor hall call is canceled in the subsequent elevator of Unit 1 so that it will not stop at the 3rd floor hall even if there are no users. When a passenger is on the bus, the inconvenience that the operation is delayed can be surely prevented.

  In addition, if a single user on the hall presses multiple hall buttons at the same time, it can be alerted that it may cause a delay in the operation of the elevator. It becomes possible to make the user know that the operation leads to a delay in operation, which is useful for gradually reducing the number of users who press a plurality of landing buttons at once.

  Although the embodiments have been described above, these embodiments are given as examples and are not intended to limit the scope of the invention. Various omissions, substitutions, and changes are possible without departing from the spirit of the present invention. The claims and their equivalents are intended to cover the embodiments or improvements thereof within the spirit of the invention.
