(Embodiment)
Hereinafter, the elevator control device according to the present embodiment will be described with reference to the accompanying drawings.

FIG. 1 is a schematic configuration diagram showing an example of an elevator according to the present embodiment. The elevator shown in FIG. 1 is for transporting a user by raising and lowering the car 1 between the 1st floor and the 5th floor of the building, and the car 1 and the balanced weight 2 are connected by a main rope 3. The main rope 3 is laid over the drive sheave 4 and the deflector 5 connected to the electric motor M, and the frictional force between the drive sheave 4 driven by the electric motor M and the main rope 3 is used to drive the car. It is a so-called traction type elevator that raises and lowers 1 in the hoistway 6.

Hall call buttons 7a to 7e are installed at the landings (halls) H1 to H5 on each floor from the first floor to the fifth floor of the building. These hall call buttons 7a to 7e are buttons operated by the user to call the hall in a designated direction in the hall on each floor. Therefore, the hall call button 7a installed in the hall H1 on the first floor, which is the lowest floor of the building, is composed only of a button for calling the hall in the upward direction because the direction of the user's destination is only upward. The hall call button 7e installed in the hall H5 on the 5th floor, which is the top floor of the building, is composed only of a button for calling the hall in the downward direction because the direction of the user's destination is only downward. In addition, the hall call buttons 7b to 7d installed in the halls H2 to H4 on the second to fourth floors, which are the intermediate floors, are a button for calling the hall in the upward direction and a button for calling the hall in the downward direction. It is composed of a combination of and.

Inside the car 1, a car call button 8 is installed, which is operated by a user who gets into the car 1 to call the car. The car call button 8 is configured by combining buttons corresponding to each floor of the 1st to 5th floors so that a user who gets into the car 1 can call a car with a designated destination floor. Further, the car 1 is provided with a load sensor 9 for detecting the load of the car 1 and a position detector 10 for detecting the current position of the car 1. The position detector 10 is, for example, a detector that detects the position of the car 1 based on a pulse output from the encoder in response to the rotation of a roller that rolls along a guide rail (not shown). Any known detector for detecting the position can be used. Further, the car 1 may further be provided with a buzzer or a display device for notifying the fact when the car is full.

A machine room 11 is provided in the upper part of the hoistway 6 where the car 1 moves up and down. In the machine room 11, an elevator control panel 12 is installed together with the above-mentioned electric motor M, a drive sheave 4, a deflecting wheel 5, and the like. The elevator control panel 12 comprehensively controls the operation of the entire elevator, and the above-mentioned hall call buttons 7a to 7e, the car call button 8, the load sensor 9, and the position detector 10 are attached to the elevator control panel 12. It is connected. The elevator control device according to the present embodiment is realized as one function of the elevator control panel 12.

FIG. 2 is a block diagram showing a functional configuration of the elevator control device 100 according to the present embodiment. As shown in FIG. 2, the elevator control device 100 according to the present embodiment has a nominal setting unit 101, a load information acquisition unit 102, a car position / direction recognition unit 103, an operation control unit 104, and a resident number information acquisition unit 105. Each function configuration is provided. These functional configurations are realized, for example, by reading a program stored in a program ROM of the elevator control panel 12 by an arithmetic unit (CPU) and loading it onto the main memory of the elevator control panel 12.

When any one of the hole call buttons 7a to 7e is operated by the user, the call setting unit 101 receives and sets the hole call corresponding to the operated hole call button, and sets the operated hole call button. By turning it on, control is performed to notify the user that the hall call has been registered. Further, when the car 1 lands on the floor where the hall call is made in response to the hall call, the call setting unit 101 controls to turn off the operated hall call button on the floor. In this way, the call setting unit 101 sets the hole call by inputting the hole call button.

Further, the call setting unit 101 accepts and sets the car call when the car call button 8 is operated by the user who got into the car 1, and also lights the car call button 8 to call the car. Controls to notify the user that is registered. Further, the call setting unit 101 controls to turn off the car call button 8 when the car 1 lands on the floor designated by the car call in response to the car call.

Further, the call setting unit 101 sets the hole call each time the hole call corresponding to the user's button operation on the hole call button 7 is input. Further, the call setting unit 101 sets the car call each time a car call corresponding to the user's button operation on the car call button 8 is input. Here, the setting of a hall call or a car call means a process of memorizing the floor and the direction of the call in the case of a hall call, and the designated destination floor in the case of a car call. Further, the response to the call means that the car 1 is landed on the floor where the hall call was made or the destination floor designated by the car call. The hole call and the car call set by the call setting unit 101 are deleted when the call is answered.

Further, the call setting unit 101 stores the set registration order of the hole calls, that is, the order in which the hole calls in the unanswered state are input.

The load information acquisition unit 102 acquires the load of the car 1 detected by the load sensor 9. The load information acquisition unit 102 outputs the load of the car 1 to the operation control unit 104.

Based on the output from the position detector 10, the car position / direction recognition unit 103 recognizes which floor from the 1st floor to the 5th floor of the building the car 1 is currently on, and immediately before that. The moving direction of the car 1 is recognized based on the positional relationship between the landing floor and the current landing floor and the presence or absence of an unanswered call. The car position / direction recognition unit 103 outputs the recognized information such as the current landing floor to the operation control unit 104.

The operation control unit 104 controls the electric motor M and the car 1. Specifically, the operation control unit 104 determines the response floor based on the hall call / car call set by the call setting unit 101, and corresponds to the distance from the current position of the car 1 to the response floor. Then, the acceleration and deceleration of the car 1 and the maximum speed of the car 1 are determined. Then, a movement pattern determined from the acceleration, deceleration, maximum speed, and movement distance of the car 1 is obtained, and the vehicle M is moved from the current position to the response floor according to this movement pattern. Output a control command.

Further, the operation control unit 104 compares the load information of the car 1 acquired from the load information acquisition unit 102 with a predetermined threshold value, and determines whether or not the car 1 is in a full state. When the operation control unit 104 determines that the car is full when the floor is on the floor, the operation control unit 104 notifies the car 1 that the car is full. In response to the notification, the car 1 outputs a buzzer notifying that the car is full, or displays that the car is full on the display device.

Further, when the operation control unit 104 determines that the car 1 is full, the operation control unit 104 notifies the car 1 that the car 1 is full. Further, the operation control unit 104 indicates that the load capacity at the time when the car 1 lands on a predetermined intermediate floor is full, and after the vehicle 1 departs from the intermediate floor, the call setting unit 101 determines. When the hall call on the middle floor is set, the threshold value of the load load indicating the full capacity when the floor is landed on the floor before the middle floor in the next lap is lowered to determine whether or not the hall is full.

For example, when the operation control unit 104 departs downward on the third floor, which is a certain intermediate floor, with the load indicating full, the call setting unit 101 moves downward on the intermediate floor within a predetermined time. When the hall call is set, the threshold value of the load capacity indicating the fullness when landing on the 5th and 4th floors in the next lap is lowered to determine whether or not the hall is full. Here, the next lap means the next movement in the same direction as when the threshold value is lowered. Therefore, when the threshold value is lowered during the downward movement, the operation control unit 104 applies the threshold value changed at the time of the next downward movement, when the floor above the middle floor is determined to be full.

Here, an example of operation control of the car 1 based on the change of the threshold value will be described with reference to FIGS. 3A and 3B. First, FIG. 3A is a diagram showing an example of changing the threshold value after passing through an intermediate floor. Here, the standard threshold value is a load capacity equivalent to 5 people.

First, it is assumed that five people can ride in the car 1 on the top floor. Then, it becomes full, and in this state, it moves downward. In addition, on the top floor, there are leftovers of 4 people. It is also full when the car 1 departs after landing on the 3rd floor of the middle floor. On the 3rd floor, there are 5 people left unloaded. Here, when the call setting unit 101 sets a downward hall call on the third floor, the operation control unit 104 indicates a full load when landing on the fifth and fourth floors in the next lap. Let the threshold value of be the value of the load capacity equivalent to two people.

FIG. 3B is a diagram showing an example of operation control of the car 1 in the next lap of FIG. 3A. As explained in FIG. 3A, the threshold value of the load capacity indicating the full capacity when landing on the 5th and 4th floors is the value of the load capacity equivalent to 2 people. , Notify that it is full. Then, the car 1 departs from the top floor when two people get on board. Then, on the 3rd floor, 3 people can get on the car 1. At this point, two people are left unloaded on the third floor.

In this way, the operation control unit 104 departs from the middle floor in a full state, and when the hall call in the same direction is set on the middle floor, the operation control unit 104 is full on the floor before the middle floor in the next lap. By lowering the threshold value indicating that, in the next lap, the passengers can get on the middle floor without actually filling up the top floor, so that the passenger rate on the middle floor can be increased and controlled.

Further, when the operation control unit 104 lands on the intermediate floor and departs from the intermediate floor in the next lap after the above-mentioned threshold value change, the load capacity at the time of departure indicates that the intermediate floor is full. Driving control is performed with the floors above the floor as the passing floor. For example, in the example of FIG. 3B, when departing from the third floor, the operation control unit 104 passes through the second floor and lands on the entrance floor if there is no hall call on the second floor.

As described above, when the operation control unit 104 controls the traveling with the floors prior to the intermediate floor as the passing floor, the operation control unit 104 preferentially lands the floor as the passing floor in the next round. For example, in the example of FIG. 3B, although there is a hall call on the 2nd floor, when leaving the 3rd floor, the operation control unit 104 passes through the 2nd floor and lands on the entrance floor because it is full. In the next lap, the changed threshold is maintained, and after leaving the 5th floor, the aircraft passes through the 4th and 3rd floors and is landed on the 2nd floor.

In addition, the operation control unit 104 will be cleared from the full state when leaving the intermediate floor on the intermediate floor that triggered the change of the threshold value, or the hall call in the same direction will not be set on the intermediate floor. If so, the changed threshold is returned to the original threshold.

It should be noted that the operation control unit 104 changes the threshold value based on the number of staying people in the middle floor that triggered the change of the threshold value among the number of staying people on each floor acquired from the staying person number information acquisition unit 105. You may do it. For example, if the number of people staying on the middle floor is only one, the operation control unit 104 may change the threshold value to a load reduced by one person. In this way, the operation control unit 104 may lower the threshold value based on the number of resident persons at the time of landing on the intermediate floor.

The staying person number information acquisition unit 105 acquires image pickup data from an image pickup device installed near the door of the car 1 on each floor, analyzes the image pickup data, and identifies the number of people on each floor. Get the number of people staying in. Further, the staying person number information acquisition unit 105 may acquire the staying person number from a sensor such as a motion sensor installed near the door of the car 1 on each floor.

Subsequently, the procedure of the threshold value change processing will be described with reference to FIG. FIG. 4 is a flowchart illustrating the procedure of the threshold value change process.

First, the operation control unit 104 determines whether or not the load state indicates fullness when the car 1 departs from the middle floor (step S1). In step S1, when the seat is full (step S1: Yes) and the call setting unit 101 sets the hall call on the intermediate floor within a predetermined time after leaving the intermediate floor (step S2: Yes). The operation control unit 104 changes the threshold value of the floor before the middle floor in the next lap (step S3). If the conditions of step S1 and step S2 are not satisfied (step S1 or step S2: No), the process ends without changing the threshold value.

When the threshold value change condition is satisfied on the middle floor in the next lap (step S4: Yes), the threshold value is maintained, and when the threshold value change condition is not satisfied on the middle floor in the next lap (step S4: No), the operation is performed. The control unit 104 returns the threshold value to the original value (step S5), and ends the process.

In the elevator control device 100 according to the present embodiment, the load information acquisition unit 102 acquires the load information of the car 1, and the call setting unit 101 sets the hall call by inputting the hole call button. The operation control unit 104 departs from the middle floor in a full state, and when a hall call in the same direction is set on the middle floor, the threshold value indicating the fullness of the floors before the middle floor in the next lap is set. Lower.

In this way, the elevator control device 100 departs on the middle floor in a full state, and when the condition that the hall call in the same direction is set on the middle floor is satisfied, the elevator control device 100 lowers the threshold value indicating the fullness to the next time. In the lap of the above, it is possible to increase the boarding efficiency of the middle floor and control it with only one elevator because the seat that can be boarded on the middle floor is secured without making the top floor actually full.

Further, if the load capacity at the time of landing on the intermediate floor and departing from the intermediate floor in the next lap indicates that the load is full, the operation control unit 104 passes through the floors ahead of the intermediate floor. Run control as a floor. In this case, the elevator control device 100 can prevent deterioration of operating efficiency because it is possible to omit unnecessary stop / departure control on the floors beyond the middle floor.

Further, when the operation control unit 104 controls the traveling with the floors prior to the intermediate floor as the passing floor, the operation control unit 104 preferentially lands the floor as the passing floor in the next round. In this way, the operation control unit 104 can prevent the boarding efficiency of the passing floor from deteriorating by preferentially landing the floor once passed on the next lap.

Further, the operation control unit 104 changes the threshold value based on the number of resident people on the middle floor that triggered the change of the threshold value. In this way, the operation control unit 104 can prevent the threshold value from being unnecessarily lowered by changing the threshold value based on the number of resident people on the middle floor.

The program executed by the elevator control device 100 described above has a modular configuration including functional blocks that can be realized by the program among the functional blocks of the elevator control device 100 of FIG. 2 described above.
