Description

Technical Field

[0001] The present invention relates to a control device, a control method and an elevator having a non-contact operating panel in a car or a landing. Background Art

[0002] In recent years, more and more elevators have non-contact operating panels in the car or at the landing. In addition to the buttons for specifying the destination floor as in the past, the non-contact operating panel also has a non-contact sensor that detects the destination floor in a non-contact manner when a part of a human body approaches, and performs elevator control based on the detection from either the button or the non-contact sensor.

[0003] As an example, for example, in Patent Document 1, in an elevator including an operating panel capable of detecting contact operation and non-contact operation, in order to reduce erroneous detection of non-contact operation, the elevator is configured as follows: "The elevator includes: an operating panel having a contact operation detection unit capable of detecting contact operation and a non-contact operation detection unit capable of detecting non-contact operation; and an operation acceptance determination unit that determines whether to accept the non-contact operation, and when the contact operation detection unit detects a contact operation, if the non-contact operation detection unit detects a non-contact operation within at least one of a first period from a predetermined time earlier than the time point when the contact operation is detected to the time point and a second period from the time point to a predetermined time later, the operation acceptance determination unit does not accept the non-contact operation." Prior art literature Patent Literature

[0004] Patent Document 1: Japanese Patent No. 7006758 Summary of the invention Technical problem to be solved by the invention

[0005] According to Patent Document 1, the contactless operation can be prevented by invalidating the contactless operation in the period before and after the contact operation. However, in order to determine whether there are multiple call inputs within a certain period of time, monitoring for a certain period of time is required, and a time lag (deterioration of responsiveness) occurs from the user's operation to the lighting, thereby deteriorating the user's operating feeling (because it does not respond immediately, it gives the impression of inconvenience in use), which is a problem.

[0006] Therefore, the object of the present invention is to provide a control device, a control method and an elevator of a contactless operating panel, which can perform processing from receiving a user's operation to executing a lighting control of the received operation in a short time, and can solve the problem of unnecessary call registration detected by multiple sensors.

[0007] In order to achieve the above-mentioned purpose, in the present invention, it is set as "a control device of a non-contact operating panel, which is arranged in the elevator car or the floor station, including buttons for the destination floor or the up and down directions and a non-contact sensor. The control device of the non-contact operating panel is characterized in that it includes: an input processing unit, which inputs and processes the detection signal from the non-contact sensor; and a destination floor registration processing unit, which lights up the button according to the detection signal, and when a plurality of detection signals from the non-contact sensor are generated within a specific period, the button that is lit within the specific period is extinguished. "

[0008] In the present invention, it is set as "a control method of a non-contact operating panel, which is arranged in the elevator car or floor station, including buttons for the destination floor or up and down directions and a non-contact sensor. The control method of the non-contact operating panel is characterized in that the button is lit according to the detection signal from the non-contact sensor, and when a plurality of detection signals from the non-contact sensor are generated within a specific time limit, the buttons generated within the specific time limit are extinguished."

[0009] In addition, in the present invention, it is set as "an elevator including buttons for destination floors or up and down directions and non-contact sensors arranged in a car or a floor station, and the elevator is characterized in that the buttons are lit according to the detection signals from the non-contact sensors, and when multiple detection signals from the non-contact sensors are generated within a specific time limit, the buttons generated within the specific time limit are extinguished."

[0012] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Example 1

[0013] First, use Figure 1 The following is a structural example of an elevator according to an embodiment of the present invention. Figure 1 As shown, the elevator 100 moves up and down in a hoistway 110 formed in a building structure. The elevator 100 includes a car 1 for loading people and goods, a main rope 3, a counterweight 2, and a traction machine 4. In addition, the elevator 100 includes an in-car operating panel 7 (equivalent to the elevator operating panel of the present invention) arranged inside the car 1 and a landing operating panel 8 arranged at the landing.

[0014] The hoistway 110 is a space for the car 1 to rise and fall, and is arranged to penetrate each floor inside the building in the up-down direction. A guide rail (not shown) for guiding the rise and fall of the car 1 is installed on the inner wall surface of the hoistway 110. In addition, a landing door 111 leading to each floor is arranged at a height position corresponding to each floor on the wall surface of the hoistway 110. In addition, a machine room 160 is arranged at the top of the hoistway 110, and a pit 180 is arranged at the bottom of the hoistway 110.

[0015] The car 1 is formed in a hollow substantially rectangular parallelepiped shape. The car 1 is connected to the counterweight 2 by a main rope 3 and is raised and lowered in a hoistway 110. The car 1 is guided by a guide rail provided on a wall surface in the hoistway 110 and is raised and lowered in the hoistway 110 in an up-and-down direction. A car door (not shown) is provided on the side of the car 1 at a position corresponding to the landing door 111. When the car 1 stops at each floor, the car door and the landing door 111 are opened, so that people and goods can enter and leave the car 1.

[0016] One axial end of the main rope 3 is connected to the upper part of the car 1, and the other end is connected to the upper part of the counterweight 2. In addition, the middle part of the main rope 3 is wound on the traction machine 4 installed in the machine room 160, and is installed on a return pulley (not shown) installed near the traction machine 4.

[0017] The counterweight 2 is stored in the hoistway 110 in a state of being suspended from the other end of the main rope 3. The counterweight 2 is raised and lowered in the hoistway 110 along the counterweight side guide rail (not shown). The traction machine 4 is set on a machine beam (not shown), which is set in the machine room 160 of the hoistway 110. In addition, the traction machine 4 has a traction sheave around which the main rope 3 is wound. Moreover, the traction machine 4 is driven to rotate under the control of the traction machine drive control unit 21 described later, so that the car 1 and the counterweight 2 are raised and lowered in a bucket manner through the main rope 3.

[0018] The landing operation panel 8 is arranged near the landing door 111 of each landing, and a button indicating the destination direction (hall button) is arranged on the landing operation panel 8. In the present embodiment, the landing operation panel 8 is composed of push-type buttons indicating the destination direction of the upward direction and the downward direction, but it can also be a non-contact operation panel like the in-car operation panel 7. In addition, the landing operation panel 8 arranged at the landing on the uppermost floor is only provided with a button indicating the downward direction, and the landing operation panel 8 arranged at the landing on the lowermost floor is only provided with a button indicating the upward direction.

[0019] The in-car operating panel 7 (equivalent to the elevator operating panel of the present invention) is provided near the car door inside the car 1 . Figure 2 1 is a schematic diagram of the structure of the car operating panel 7 according to the embodiment of the present invention. The car operating panel 7 includes an input unit 70 (71 to 75) for the user to input a predetermined destination floor, an opening and closing button 80 for inputting an opening and closing operation of the car door, and a display unit 76 for displaying the travel floor and the stop floor of the car 1. The car operating panel 7 is electrically connected to the elevator control device 20 installed in the machine room 160 through a connection unit 9 that connects the car operating panel 7 to the connection unit 9.

[0020] The input unit 70 (71 to 75) is provided with a predetermined number of floors (five floors in this embodiment) according to the stop floor of the elevator 100. The input units 71 to 75 include push-button units 50 (51 to 55), sensor units 60 (61 to 65) provided on the surface of the button units 50 (51 to 55), and response lamps 40 provided for each button unit 50 (51 to 55). In the following description, when the input units 71 to 75 are not particularly distinguished, the input units 71 to 75 are simply referred to as the input unit 70. In addition, when the button units 51 to 55 are not particularly distinguished, the button units 51 to 55 are simply referred to as the button unit 50. In addition, when the sensor units 61 to 65 are not particularly distinguished, the sensor units 61 to 65 are simply referred to as the sensor unit 60.

[0021] The button unit 50 is circular in shape, and a number indicating a destination floor is displayed on the surface of each button unit 51 to 55 (in Figure 2 , "1", "2", "3", "4", "5" in the figure). The button portion 50 is operated by being pressed by the user. When the button portion 50 is pressed, a button input signal is generated by the button input detection portion 33 described below, and the generated button input signal is sent to the input processing portion 25. In addition, the shape of the button portion 50 is not limited to a circle, and may be various other shapes such as a quadrilateral or an ellipse.

[0022] On the other hand, the sensor unit 60 is composed of, for example, an infrared sensor or an electrostatic sensor, and is provided, for example, on the upper side of the button unit 50. The sensor unit 60 is a sensor that detects an object such as a finger or a hand approaching the sensor unit 60 in a non-contact state, and is configured to detect an object within a range of, for example, about 10 mm to 30 mm from the input unit 70. By detecting the object in the sensor unit 60, a sensor input signal is generated in the sensor input detection unit 34 described later, and the generated sensor input signal is sent to the input processing unit 25 (see Figure 3 ).

[0023] The response lamp 40 is provided on each push button unit 50, and is lit according to the registered destination floor information sent from the destination floor registration processing unit 24 described later. For example, the response lamp 40 may be provided around the button unit 50 and a part of the button unit 50 may be lit, or the response lamp 40 may be provided on the back side of the button unit 50 and the entire button unit 50 may be lit. The lighting of the response lamp 40 notifies the user of the registered destination floor.

[0024] The display unit 76 displays the floor through which the car 1 passes, the next stop floor, etc., on a monitor constituted by, for example, an LCD (Liquid Crystal Display) or the like. In addition, the display unit 76 can display various information such as date and weather.

[0025] Figure 3 1 is a diagram showing an example of the overall structure of an elevator control. The elevator control is composed of an elevator control device 20, an in-car operating panel 7, and a landing operating panel 8. The in-car operating panel 7 and the landing operating panel 8 include a response lamp 40, a button unit 50, and a sensor unit 60. In addition, in the following description, an example in which the landing operating panel 8 is also a non-contact operating panel is shown.

[0026] The operation control unit 24 in the elevator control device 20 inputs the detection signals from the button unit 50 and the sensor unit 60 in the car operating panel 7 and the landing operating panel 8 to the input processing unit 25, and the destination floor registration processing unit 23 in the car and the destination floor registration processing unit 22 at the landing process respectively process the signals to register the call, and provide an output command to the traction machine drive control unit 21, thereby controlling the elevator car 1 to run to a specified floor. In addition, in the destination floor registration processing unit 23 in the car and the destination floor registration processing unit 22 at the landing in the operation control unit 24, the lighting of the response lamp 40 in the car operating panel 7 and the landing operating panel 8 corresponding to the call registration is appropriately controlled.

[0027] The present invention achieves a response to the following situation: in an elevator equipped with the above-mentioned equipment, for example, due to approaching or luggage approaching, the plurality of sensors of the sensor unit 60 of the in-car operating panel 7 detects and thus call registration is performed unnecessarily. Figure 4 This shows an example in which a human hand approaches the sensor portion 60 due to an accidental bounce, and the sensors on the 5th, 6th, 15th, and 16th layers perform detection actions almost simultaneously.

[0028] In order to cope with such an event, in the embodiment of the present invention, the destination floor registration processing unit 23 in the car and the destination floor registration processing unit 22 at the landing are as follows: Figure 5 However, this processing is a processing in the destination floor registration processing section corresponding to the non-contact operation panel.

[0029] Assume that Figure 5 After the processing is started in the processing step S11, the sensor detection is performed in the processing step S12. In addition, in the processing step S13, the call registration is performed upon receiving the detection, and the lighting of the response lamp 40 in the car operating panel 7 is controlled. In addition, here, an example of implementing the processing by the destination floor registration processing unit 23 in the car is described with the non-contact operating panel 7 in the car as the object.

[0030] In the sensor detection at this time, there is a situation where a floor is designated and it is considered to be a normal operation, and Figure 4 In the illustrated case where multiple floors are designated in a short period of time and considered as abnormal operation, in processing step S14, it is determined whether there are two or more sensors detecting and performing call registration. In the case of a single detection ("No" in processing step S14), it is determined to be a normal operation, and the process is transferred to processing step S17 to maintain the call registration operation.

[0031] In the case where multiple calls are detected ("Yes" in processing step S14), in processing step S15, normal and abnormal discrimination based on time width is further performed. Specifically, in processing step S15, after the first sensor is activated, it is determined whether there are call registrations of more than a specified number within a specific time limit. As a result of this judgment, if there are no call registrations of more than a specified number within a specific time limit ("No" in processing step S15), it is determined that it is an event in which multiple people sequentially specify different floors at sufficient time intervals, and it is determined as an event of normal operation, and the process is transferred to processing step S17 to maintain the call registration action. In addition, the operation of the elevator can be started after a sufficient time has passed to confirm the passage of the specific time limit.

[0032] On the other hand, when there are more than a certain number of call registrations within a certain time period ("Yes" in processing step S15), it is determined that such a call has indeed occurred. Figure 4 In the event shown, the processing of processing step S16 is executed. In processing step S16, all call registrations registered during the specific time limit are cancelled, and the response lamp 40 in the car operating panel 7 is controlled to be turned off. In addition, in this case, a guidance broadcast or display indicating that it is an error display can also be performed.

[0033] In addition, although the above-mentioned embodiment is described using the control device of a contactless operating panel installed in the elevator car or in the floor station and equipped with a contactless sensor for each destination floor as an example, this is also applicable to the contactless sensors corresponding to the up and down buttons, and can deal with the erroneous display caused by the simultaneous response of the contactless sensors of the up button and the down button.

[0034] Furthermore, the configuration may include a selection unit that selects one of the plurality of detection signals when the detection signals are input from the plurality of non-contact sensors due to a user's erroneous operation or the like. In this case, the destination floor registration processing unit 23 in the car or the destination floor registration processing unit 22 at the landing may also be configured to keep the button corresponding to the detection signal selected by the selection unit lit, and to turn off the button that is lit during a specific time period other than that. In addition, it is preferable to keep the destination floor registration of the lit button and cancel the destination floor registration of the turned-off button. Furthermore, the selection unit may also be configured to be included in the input processing unit, or to be included in the destination floor registration processing unit in the car or the destination floor registration processing unit at the landing.

[0035] Furthermore, the detection signal selected by the selection unit may be, for example, a detection signal corresponding to the destination floor expected by the user, which is inferred by the selection unit or an external device. With this structure, the destination floor registration of the destination floor selected by the selection unit is maintained without being cancelled, thereby saving the user the trouble of selecting the destination floor again after an erroneous operation occurs, and improving the convenience of the user compared to a structure that deletes all call registrations of buttons that are lit within a specific time limit.

[0036] According to the first embodiment, the process from receiving the user's operation to executing the lighting control in response to the received operation can be performed in a short time, and the problem of unnecessary call registration due to detection by a plurality of sensors can be solved. Example 2

[0037] In Example 1 Figure 5In the processing flow of , call registration is performed first, and then the process of maintaining call registration or canceling all call registration is determined. In contrast, in embodiment 2, the following process is adopted: it is determined whether to perform temporary registration first and then change the temporary registration to call registration, or to cancel the temporary registration after a specified time.

[0038] In summary, whether in Example 1 or Example 2, it is sufficient to prevent the following situation: due to the proximity of the non-contact operating panel or the approach of a bag, multiple sensors detect it, thereby unnecessarily registering a call and starting the operation of the elevator.

[0039] In the first embodiment, an event occurs in which the response lamp 40 in the in-car operating panel 7 flashes, but in the second embodiment, the response lamp 40 does not flash, thereby providing a sense of security.

[0040] Proceed as follows Figure 6 The process of Example 2 of . Assume that Figure 6 After the processing is started in the processing step S11, the sensor detection is performed in the processing step S12. In addition, in the processing step S13A, the temporary registration is performed upon receiving the detection, and the response lamp 40 in the in-car operating panel 7 is controlled to light up. However, as described below, the temporary registration is canceled by the call registration or after a certain period of time. In addition, here, the example of the in-car destination floor registration processing unit 23 implementing the processing is described with the non-contact operating panel 7 in the car as the object.

[0041] In the sensor detection at this time, there is a situation where it is considered to be normal operation because there is a designated floor, and Figure 4 As shown in the figure, multiple floors are designated in a short time and it is considered as an abnormal operation. Therefore, in the processing step S14A, it is determined whether it is in a state of temporary registration due to detection by two or more sensors. In the case of a single detection ("No" in the processing step S14), it is determined to be a normal operation, and the process is transferred to the processing step S17A, and the temporary registration is changed to the call registration, and the response lamp 40 is displayed for the first time. In addition, the operation of the elevator can be started after a sufficient time has passed to confirm the passage of a specific time limit.

[0042] In the case of multiple detections ("Yes" in processing step S14A), in processing step S15A, normal and abnormal discrimination based on time width is further performed. Specifically, in processing step S15A, after the first sensor is activated, it is determined whether there are more than a specific number of temporary registrations within a specific time limit. As a result of this judgment, if there are no more than a specific number of temporary registrations within a specific time limit ("No" in processing step S15A), it is determined that it is an event in which multiple people sequentially specify different floors at sufficient time intervals; it is determined that it is an event caused by normal action, and the process is transferred to processing step S17A to perform the action of call registration and display of the response light 40.
