Description

[Technical field]

[0001] The present invention relates to a hall call control device, and more particularly to a control device when a hall user passes a car. [Background technology]

[0002] Generally, each elevator hall is equipped with a hall call button for making hall calls. Elevator users can register an elevator hall call by operating the hall call button for the direction they wish to go. However, if a user misses a car when it arrives at a hall, the hall call registration is erased, and the elevator user must operate the hall call button again to register a hall call.

[0003] When the elevator car is full, the elevator may perform a "full pass-through" operation in which the elevator passes through the hall where the call is registered without stopping, and prioritizes the transportation of passengers. For example, Patent Document 1 discloses an elevator operation method in which, when the elevator performs a full pass-through operation, after the transportation of passengers is completed, the elevator automatically performs a hall call registration for the floor that the elevator passed through, thereby providing priority service.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of a hall call control device according to the present invention will be described in detail with reference to the drawings. The embodiment described below is merely an example, and the present invention is not limited to the following embodiment. In addition, the present invention includes a form obtained by selectively combining multiple embodiments and modified examples described below.

[0010] The overall configuration of an elevator 1, which is an example of an embodiment of the present invention, will be described in detail with reference to Figure 1. Hereinafter, a person riding in the car 10 will be referred to as a passenger 100, and a person located at the hall 20 who wishes to use the elevator 1 will be referred to as a user 200.

[0011] Fig. 1 is a diagram showing the overall configuration of an elevator 1. The elevator 1 is an elevator device that includes a car 10 for carrying people and objects, and that transports people and objects by moving the car 10 up and down in a hoistway 5 and stopping at landings 20 on each floor. The elevator 1 includes a hoist 2 as a drive device for moving the car 10 up and down. In the hoistway 5, there are installed a wire rope 3 that is wound around the hoist 2 and has one end connected to the top of the car 10, and a counterweight 4 that is connected to the other end of the wire rope 3.

[0012] The elevator 1 is equipped with a control device 30 installed at the top of the hoistway 5. The control device 30 receives signals from hall call buttons 21, which are provided at the halls 20 of each floor and are used to call the car 10, and from car buttons 13, which are provided inside the car 10 and register the destination floor. The control device 30 controls the rotation direction and speed of the motor of the hoisting machine 2 based on these signals, causing the car 10 to rise and fall.

[0013] The elevator 1 is equipped with a landing device (not shown) on the car 10, and a landing plate (not shown) in the hoistway 5. The landing device detects the landing plate, allowing the car 10 to stop at the landing platform 20 on each floor without any steps. When the control device 30 receives a signal that the landing device has detected the landing plate, it controls the door drive motor 11 to open the car door 14, and the landing platform door 22 opens in conjunction with the opening movement of the car door 14, allowing people to get on and off the car 10.

[0014] The configurations of the car 10 and the hall 20 will be described in detail with reference to Figs.

[0015] The car 10 includes a door drive motor 11 for opening and closing the car door 14. The door drive motor 11 is a drive device that is controlled by the control device 30 and opens and closes the car door 14 and the hall door 22.

[0016] The car 10 is equipped with a scale device 12 that measures the weight inside the car 10 and a car button 13 that registers the destination floor of the car 10. As will be described in detail later, the scale device 12 detects the weight of the passenger 100 inside the car 10 and transmits it to the control device 30. This detects if a user 200 has passed by. The car button 13 is installed inside the car 10, and by pressing it, the destination floor of the car 10 can be registered.

[0017] FIG. 2 is a diagram showing a configuration of a hall 20 of an elevator 1 as an example of an embodiment. The hall 20 of the elevator 1 includes a hall call button 21 for registering a call for the car 10. The hall call button 21 is preferably installed near a hall door 22. The hall call button 21 is connected to a control device 30, and when the hall call button 21 is pressed, the control unit 31 of the control device 30 registers a hall call for the hall 20 in the registration unit 32. This allows a user 200 to make a hall call for the direction he or she wants to go by pressing the hall call button 21. The hall 20 includes a camera 25 for taking an image of the hall 20 and detecting the user 200, which will be described in detail later. In addition, the hall 20 includes a display unit 23 and a sound notification unit 24 for notifying the user 200 that the hall call has been registered, which will be described in detail later.

[0018] The control device 30 of the elevator 1 will be described in detail with reference to FIG.

[0019] 4 is a block diagram of a control device 30 of an elevator 1 according to an embodiment of the present invention. The control device 30 is connected to the landings 20 on each floor, the hoist 2 that raises and lowers the car 10, and the car 10.

[0020] The control device 30 includes a registration unit 32 for registering the destination floor or hall call of the car 10 by pressing the car button 13 or the hall call button 21, etc. The control device 30 includes an operation control unit 33 for controlling the hoisting machine 2 based on the destination floor and hall call of the car 10 registered in the registration unit 32. The operation control unit 33 controls the rotation direction and speed of the motor of the hoisting machine 2, so that the car 10 can rise and fall and stop at the hall 20.

[0021] The control device 30 includes a determination unit 34 that determines whether the user 200 has passed on the basis of the information acquired by the pass-by detection unit. Although details will be described later, when the determination unit 34 determines that a pass has occurred based on the information acquired by the pass-by detection unit, the hall call for the hall 20 is re-registered in the registration unit 32 by the control unit 31. The re-registered hall call may be such that the car 10 is moved to the hall 20 with the highest priority, ignoring hall calls for other floors. Also, the car 10 may be moved to the re-registered floor while stopping in response to hall calls for other floors, in the same way as for normal hall calls.

[0022] When the hall call is re-registered in the registration unit 32, the operation control unit 33 transports the passenger 100 based on the destination floor registration of the passenger 100, and then moves the elevator car 10 to the hall 20 based on the re-registered hall call. In addition, when the elevator car 10 stops at the hall 20 in response to the re-registered hall call, if the passing-by detection unit cannot detect the user 200, the operation control unit 33 cancels the registration of the hall call at the hall 20.

[0023] The control device 30 includes an alarm control unit 35 that controls the display unit 23 and sound alarm unit 24 for notifying the user 200 that a hall call has been registered in the registration unit 32. The alarm control unit 35 controls the display unit 23 and sound alarm unit 24 installed at the hall 20 to notify the user 200 of guidance information when the destination floor and hall call are re-registered in the registration unit 32 by the control unit 31. When the hall call is re-registered in the registration unit 32, the alarm control unit 35 causes the display unit 23 and sound alarm unit 24 to notify the user 200 that the hall call has been re-registered.

[0024] The passing-through according to the present invention will be described in detail with reference to FIG.

[0025] FIG. 3 is a diagram showing a situation in which the user 200 may pass the car 10 when the car 10 arrives at the hall 20 of the elevator 1, which is an example of an embodiment. In the elevator 1, the user 200 registers a hall call, and the car 10 arrives at the hall 20 in response to the registration. Usually, the user 200 gets on the car 10 and moves to a floor. However, when the car 10 arrives at the hall 20, the user 200 may pass the car 10 and wait for the next car 10. The reason for the user 200 passing the car 10 includes a case where the user 200 has large luggage or a case where the user wants to avoid crowding in the car 10. The passing of the user 200 is detected by a passing detection unit, which will be described in detail later.

[0026] The hall call re-registration process will be described in detail with reference to Fig. 5. The description will also be made with reference to Figs. 1 to 4 and Figs. 6 to 8 as appropriate.

[0027] Fig. 5 is a flow chart for explaining the re-registration process of a hall call. When a user 200 at a hall 20 presses a hall call button 21, the hall call is registered in the registration unit 32 (step S1). When the car 10 arrives at the hall 20 for which a hall call has been made, the determination unit 34 determines whether or not the user 200 at the hall 20 has passed on the floor based on information acquired from the pass-by detection unit when the door is opened and closed (step S2). When the determination unit 34 determines that a pass-by has occurred (YES in step S3), the control unit 31 re-registers the hall call in the registration unit 32 (step S5). The pass-by determination in step S2 is a pass-by determination process by the pass-by detection unit, which is shown in Figs. 6 to 8 described later.

[0028] The pass-by detection unit will be described in detail with reference to FIGS.

[0029] The passing-over detection unit detects a so-called passing-over, which is when a user 200 registers a hall call and, when the car 10 arrives at the hall 20, waits for the next car 10 without getting on the car 10. The pass-by detection unit transmits the acquired information to the determination unit 34, and the determination unit 34 determines whether or not an object has been passed over. The pass-by detection unit is at least one of the scale device 12 and the camera 25.

[0030] The weighing device 12 is installed under the car 10, detects a change in weight inside the car 10, and transmits the weight data to a judgment unit 34 of the control device 30. The judgment unit 34 judges the weight change every time the weight inside the car 10 changes while the car 10 is stopped at the landing 20. The weight change is judged as no change, an increase, or a decrease.

[0031] The determination unit 34 determines that the user 200 has passed if there is no change or only a decrease in weight change when the door is opened or closed. For example, if two people get off the car 10 while the door is opened and closed, the weight change detected by the scale device 12 is only a decrease, so the determination unit 34 determines that the user has passed. On the other hand, if two people get off the car 10 and one person gets on the car 10 while the door is opened and closed, the weight change detected by the scale device 12 is a decrease and an increase, so the determination unit 34 determines that the user has not passed.

[0032] When determining whether or not there is a weight change, the determination unit 34 may set a certain threshold value since minute changes in weight may occur due to the movement of the passenger 100, etc. In this case, an increase or decrease in weight within the certain threshold value may be determined as no weight change. For example, if the threshold value is 5 kg, a decrease or increase of 3 kg is determined as no weight change.

[0033] The control device 30 may set a reference value for the occupancy rate in the car 10. In this case, the judgment unit 34 may calculate the occupancy rate in the car 10 from the weight data acquired from the scale device 12. When the occupancy rate in the car 10 is high, the user 200 is likely to pass the car 10. On the other hand, when the occupancy rate in the car 10 is low and there is space for the user 200 to board, the user 200 is unlikely to pass the car 10. Therefore, the judgment unit 34 may perform a pass-by judgment when the calculated occupancy rate is higher than the reference value. On the other hand, the judgment unit 34 may not perform a pass-by judgment when the calculated occupancy rate is lower than the reference value. In this way, by limiting the conditions for re-registration of hall calls, it is possible to reduce unnecessary re-registration of hall calls and improve operation efficiency.

[0034] The pass-by detection by the scale device 12 will be described in detail with reference to FIG.

[0035] 6 is a flowchart explaining the pass-by judgment process when the pass-by detection unit is the weighing device 12. The judgment unit 34 judges the weight change every time the weight inside the car 10 changes while the car 10 is stopped at the hall 20. The weight change is judged as an increase or decrease, and a certain threshold may be set, and a weight change within the threshold may be judged as no weight change.

[0036] If the weight inside the car 10 does not change (NO in step S21) when the door is opened or closed (step S20), the judgment unit 34 judges that an overshoot has occurred (step S24). Also, if the weight inside the car 10 has changed (YES in step S21) and no increase in weight is detected in the weight change during the opening and closing of the door (NO in step S22), the judgment unit 34 judges that an overshoot has occurred (step S24). On the other hand, if an increase in weight change inside the car 10 is detected during the opening and closing of the door (YES in step S22), the judgment unit 34 judges that an overshoot has not occurred (step S23).

[0037] The camera 25 is installed at the landing 20, captures an image of a certain range of the landing 20, and detects the user 200 within the certain range of the landing 20. The camera 25 transmits the captured image data to the determination unit 34 of the control device 30. The determination unit 34 determines whether or not the user 200 has passed by from the image data acquired from the camera 25. When the determination unit 34 detects the user 200 at the landing 20 when the doors are opened or closed, it determines that the user 200 has passed by.

[0038] Using FIG. 7, the passing-by detection by the camera 25 will be described in detail.

[0039] Fig. 7 is a flowchart for explaining the pass-by determination process when the pass-by detection unit is the camera 25. The same reference numerals are used for the same processes as in Fig. 6. When the camera 25 detects the user 200 at the landing 20 when the door is opened or closed (step S20) (NO in step S30), the determination unit 34 determines that there has been a pass-by (step S24). On the other hand, when the camera 25 does not detect the user 200 at the landing 20 (YES in step S30), the determination unit 34 determines that there has been no pass-by (step S23).

[0040] In the case where the elevator 1 is equipped with the weighing device 12 and the camera 25, the determination unit 34 determines that a pass-through has occurred when data from at least one of the data acquired from the weighing device 12 and the camera 25 is obtained that indicates that a pass-through has occurred. For example, even if the weighing device 12 detects an increase in weight while the door is opening or closing, if the camera 25 detects the user 200 at the landing 20 when the door is opening or closing, it determines that a pass-through has occurred. On the other hand, if neither the weighing device 12 nor the camera 25 can detect a pass-through, it determines that a pass-through has not occurred.

[0041] Using FIG. 8, the passing-by detection by the scale device 12 and the camera 25 will be described in detail.

[0042] Fig. 8 is a flowchart explaining the pass-by judgment process when the pass-by detection unit is the scale device 12 and the camera 25. At this time, the judgment unit 34 judges that there has been no pass-by only if the scale device 12 and the camera 25 do not detect the user 200 passing by when the door is opened or closed. Moreover, the pass-by judgment process shown in Fig. 8 is a combination of the pass-by judgment processes shown in Fig. 6 and Fig. 7. Moreover, the same reference numerals are used for processes similar to those in Fig. 6 and Fig. 7.

[0043] When the weighing device 12 does not detect a weight change in the car 10 when the door is opened or closed (step S20) (NO in step S21), the judgment unit 34 judges that an overshoot has occurred (step S24). Also, when there is a weight change in the car 10 (YES in step S21) and the weight change is only a decrease (NO in step S22), the judgment unit 34 judges that an overshoot has occurred (step S24). Even if the weight change in the car 10 is an increase, when the camera 25 detects the user 200 at the hall 20 (NO in step S30), the judgment unit 34 judges that an overshoot has occurred (step S24).

[0044] On the other hand, when the door is opened or closed (step S20), if the weighing device 12 detects a change in weight inside the car 10 (YES in step S21), an increase in the weight change is detected (YES in step S22), and the camera 25 does not detect the user 200 at the landing 20 (YES in step S30), the judgment unit 34 judges that there is no passing (step S23).

[0045] When the determination unit 34 determines that a missed train has occurred based on the data acquired by the missed train detection unit, the control unit 31 re-registers the hall call for the hall 20 in the registration unit 32. This eliminates the need for the user 200 to register the hall call by pressing the hall call button 21 again. When the hall call is re-registered, at least one of the display unit 23 and the sound notification unit 24 notifies the user 200 that the hall call has been re-registered.

[0046] The missed detection unit detects the presence or absence of the user 200 when the car 10 arrives at the hall 20 based on the re-registered hall call. The control unit 31 cancels the hall call for the hall 20 on the condition that the user 200 is not detected. This makes it possible to prevent the re-registration of a hall call for a hall 20 where the user 200 is not present when the user 200 who originally made the hall call leaves the hall 20 after re-registering the hall call. This makes it possible to improve the operating efficiency of the elevator 1.

[0047] When the elevator car 10 arrives at the hall 20 for which the hall call has been re-registered, in the case where the weighing device 12 detects the presence or absence of the user 200, the determination unit 34 determines that the user 200 has not been detected if the weight change is only a decrease when the door is opened and closed. On the condition that the determination unit 34 determines that the user 200 has not been detected, the control unit 31 cancels the hall call for that hall 20.

[0048] When the elevator car 10 arrives at the hall 20 for which the hall call has been re-registered, in the case where the presence or absence of the user 200 is detected by the camera 25, the determination unit 34 determines that the user 200 has not been detected if the user 200 is not detected at the hall 20 before the doors are opened or closed. On the condition that the determination unit 34 determines that the user 200 has not been detected, the control unit 31 cancels the hall call for that hall 20.

[0049] When the hall call is re-registered, the display unit 23 and the sound notification unit 24 of the hall 20 notify the user 200 that the hall call has been re-registered (step S6). The operation control unit 33 transports the passenger 100 in accordance with the destination floor registration of the passenger 100 in the car 10 (step S7). After transporting the passenger 100, when the car arrives at the floor where the hall call was re-registered (step S8), if the user 200 is not detected (YES in step S9), the hall call of the hall 20 is cancelled (step S10). When the user 200 is detected (NO in step S9) and the user 200 gets on the car 10 and registers the destination floor registration by the car button 13, the user 200 is transported to the registered destination floor (step S11). On the other hand, if the determination unit 34 determines that there is no overtaking (NO in step S3), the passenger 100 is transported based on the destination floor registration of the passenger 100 (step S4).

[0050] The display unit 23 and the sound notification unit 24 will be described in detail with reference to FIGS.

[0051] As shown in FIG. 2, the display unit 23 is installed near the landing door 22 of the landing 20, and displays guidance information to the user 200. A sound notification unit 24 is installed near the display unit 23 to notify the user 200 of information by sound. The display unit 23 may be, for example, an indicator that displays the position of the elevator car 10, or may be an indicator light. Also, it is preferably a liquid crystal display. The indicator light may be, for example, an arrow shape that indicates the up and down directions of landing calls. The sound notification unit 24 is, for example, a speaker, etc.

[0052] When a platform call is registered in the registration unit 32 by, for example, pressing the platform call button 21 of the platform 20, the display unit 23 displays guidance information to the user 200 so that the user can recognize that the platform call has been registered. Here, the guidance information is, for example, platform call information, which indicates that a platform call has been registered in the registration unit 32. The display method is, for example, text, images, videos, etc. These may also be displayed simultaneously. The display unit 23 may display an image of the inside of the car 10 captured by an in-car camera (not shown) installed in the car 10.

[0053] When a call registration is registered in the registration unit 32 by pressing the hall call button 21 of the hall 20, for example, the sound notification unit 24 notifies the user 200 of the registration by sound. In addition, when a hall call is re-registered, the sound notification unit 24 notifies the user 200 of the re-registration by sound, for example. The notification method is, for example, an announcement, a touch sound, etc. The touch sound is, for example, the sound made when the hall call button 21 is pressed. In addition, the sound notification unit 24 may notify the user 200 of information by sound in accordance with the information displayed on the display unit 23. For example, the sound notification unit 24 may read out the guidance information displayed on the display unit 23. [Explanation of symbols]
