Description

  The present invention relates to an elevator, and more particularly, to an elevator provided with a non-contact type operation panel.

  A car operation panel is installed in the elevator car. The car operation panel includes a destination floor button displaying a number of the destination floor. The passenger operates the destination floor button to register the destination floor of the car moving on the hoistway. As the destination floor button, a contact type such as a push button or a graphical user interface (GUI) of a touch panel is widely adopted.

  In recent years, elevators installed in public facilities and the like have also introduced non-contact type car operation panels that can perform non-contact operation for registering a destination floor of a car in consideration of hygiene. . In this type of car operation panel, a destination floor registration operation by a passenger is detected in a non-contact manner by a distance sensor or a photoelectric sensor (for example, Patent Documents 1-3).

  In the non-contact type car operation panel described above, the following measures are taken in order to prevent erroneous registration of the destination floor unintended by the passenger. For example, by setting the detection distance of the sensor within a specific range close to the car operation panel, an operation at a position away from the sensor is not detected. In addition, by setting a certain threshold time until it is determined that the operation is detected, the detection of an accidental event such as something that causes the detection area of the sensor to glaze for a moment is eliminated.

  By the way, in a time zone where passengers using the elevator are crowded, the car may become full. In that case, a situation is assumed in which the passenger is forced to stand in a position close to the car operation panel. In addition, even if the car is not full, a situation may occur in which the passenger suddenly leans against the car operation panel, or the passenger's baggage is approaching the car operation panel without knowing it. In such a situation, there is a possibility that erroneous registration of the destination floor may occur even if the above measures are taken.

  In addition, when the hall operation panel installed in the elevator hall is a non-contact type, it is considered that the same situation can occur in the hall. Therefore, the above-mentioned problem is common not only to the car operation panel but also to the hall operation panel.

  In view of the above-described problems, an object of the present invention is to provide an elevator that can prevent erroneous registration of a destination floor unintended by a passenger even in the above situation.

  In order to achieve the above object, an elevator according to the present invention detects a non-contact type operation panel having a plurality of sensors that detect, in a non-contact manner, an operation for determining a destination floor of a car moving on a hoistway. And a control device that controls whether or not to register the destination floor based on a detection condition for performing, wherein the control device has a destination floor sensor corresponding to the destination floor of the plurality of sensors. If the operation is detected until the first threshold time, the destination floor is registered, and when the operation is detected until the second threshold time, a process for notifying that is executed and the registration is canceled. It is characterized by doing.

  Further, the plurality of sensors include an adjacent sensor adjacent to the destination floor sensor, and the control device allows both the destination floor sensor and the adjacent sensor to perform the operation before the first threshold time elapses. If detected, the destination floor is unregistered.

  Furthermore, when the third threshold time elapses after both the destination floor sensor and the adjacent sensor detect the operation, the control device performs a process of warning that both the operations are detected. It is characterized by doing.

  According to the elevator according to the present invention, even if the destination floor sensor of the non-contact type operation panel continuously detects the destination floor of the car until the first threshold time and the destination floor is registered, When the control device detects the operation continuously until the second threshold time, the control device executes a process for notifying the fact and cancels the registration, so that the erroneous registration may occur. The situation can be recognized by the passengers and re-registration operations on the destination floor can be prompted. Thereby, even if it becomes the above situations, the erroneous registration of the destination floor which a passenger does not intend can be prevented.

  Hereinafter, an embodiment of an elevator according to the present invention will be described with reference to the drawings.

<First Embodiment>
As shown in FIG. 1, an elevator 10 according to the first embodiment is a traction type elevator having a machine room 14 at the top of a hoistway 12 and is installed in a public building such as a hospital or a nursing facility, for example. . A main rope 20 is hung on a driving sheave 18 of the hoisting machine 16 installed in the machine room 14, a car 22 is connected to one end of the main rope 20, and a counterweight 24 is connected to the other end. Has been.

  Rotational power from a motor (not shown) of the hoisting machine 16 is transmitted to the drive sheave 18 via a power transmission mechanism (not shown), and when the drive sheave 18 is driven to rotate, the main rope 20 is accompanied accordingly. The car 22 suspended from the main rope 20 is guided by a guide rail (not shown) and moves up and down the hoistway.

  In the building where the elevator 10 is installed, the landings 26A, 26B, and 26C are provided for the different floors. During the operation of the elevator 10, the car 22 is on the floor where the floor is currently landing (in FIG. 1). , The landing 26C) to the next destination floor landing (for example, landing 26A) is repeated.

  A car operation panel 28 (FIG. 2) is installed in the car 22. The car operation panel 28 is provided on either one of the left and right sleeve walls on the left and right sides of the doorway (not shown) on the halls 26A, 26B, and 26C side of the car 22. A passenger who uses the elevator 10 operates the car operation panel 28 to determine the destination floor of the car 22.

  As illustrated in FIG. 2, the car operation panel 28 includes a destination floor operation unit 30 that performs an operation in which a passenger determines a destination floor of the car 22. The destination floor operation unit 30 is provided with a plurality of sensors 32A, 32B,... 32C that detect the operation in a non-contact manner. Each of the sensors 32A, 32B, ... 32C corresponds to each floor where the landings 26A, 26B, 26C are located. In this example, the first to fourth floors and the sixth and tenth floors can be destination floors. For example, the sensor 32B detects an operation for determining the second floor as the destination floor.

  In the destination floor operation unit 30, as each of the sensors 32A, 32B,... 32C, a reflective photoelectric sensor in which a projector and a light receiver are integrated is used. This reflective photoelectric sensor irradiates light from a projector and detects the presence or absence of an object based on the amount of reflected light from the object received by the light receiver. In this example, the light reception amount (sensor sensitivity) on the light receiver side is adjusted, and the detection distance of the sensor is set within a range of about 5 cm from the destination floor operation unit 30. When the reflective photoelectric sensor detects an object, a detection signal is transmitted to the control device 46 (FIG. 1) described later.

  The destination floor operation unit 30 includes a panel portion 34 having a rectangular shape, and sensors 32A, 32B,... 32C are arranged at intervals in the longitudinal direction of the panel portion 34. In the panel portion 34, rectangular holes are formed at the positions where the sensors 32A, 32B,. The reflective photoelectric sensor is housed in the back side of each rectangular hole, and each rectangular hole is covered with a protective plate 36A, 36B,. Each of the protection plates 36A, 36B,... 36C is provided with a mark for guiding a passenger's operation.

  Among the sensors 32A, 32B,... 32C, adjacent sensors have an interval of about 10 cm (generally about one fistula). By arranging each of the sensors 32A, 32B,... 32C whose detection distance is set within the above range with such an interval, the passenger stands in front of the destination floor operation unit 30 and puts their fingers and palms. Even if an operation for determining a destination floor is performed over a specific sensor, a situation in which the sensor corresponding to the adjacent floor erroneously detects the operation can be prevented as much as possible.

  On the panel portion 34, numbers indicating the corresponding floors are displayed on the left side of each of the sensors 32A, 32B,... 32C. Further, the panel portion 34 displays L-shaped separating lines 37A, 37B,... 37C for separating the combinations of the sensors 32A, 32B,. Each of these numbers and separator lines 37A, 37B,... 37C is a translucent part formed of a translucent member, and when a lamp (not shown) stored on the back side emits light, the numerals and separator lines 37A, 37B,... 37C are lit (FIG. 2 shows a state in which the translucent part corresponding to the second floor is lit).

  An opening button 38 and a closing button 40 for opening and closing a car door (not shown) are arranged in parallel at the lower part of the destination floor operation unit 30. A contact button 42 for making contact with the outside is provided on the upper part of the destination floor operation unit 30. These buttons 38, 40, and 42 are all conventionally known push buttons, but may adopt a non-contact type similarly to the destination floor operation unit 30 described above.

  The car operation panel 28 further includes a display unit 44. The display part 44 consists of a liquid crystal display, for example, and displays the information notified to a passenger, for example, the moving direction of the car 22, the passing floor of the car 22, and other passengers. The display unit 44 is provided at a position that is easier to see from passengers above the destination floor operation unit 30. The car operation panel 28 also has a built-in speaker (not shown) for outputting sound.

  The destination floor operation unit 30 of the car operation panel 28 includes the above-described protection plates 36A, 36B,... 36C and the translucent parts (numerals, separator lines 37A, 37B,. It has a flat shape provided flush with the main surface (not shown). The display unit 44 is provided flush with the flat main surface on the cab side of the destination floor operation unit 30, and the open button 38, the close button 40, and the contact button 42 are provided substantially flush. ing. Therefore, the car operation panel 28 has a flat appearance as a whole.

  The non-contact type car operation panel 28 having the above configuration is electrically connected to a control device 46 installed in the machine room 14 (FIG. 1). The control device 46 is a computer that performs overall operation control of the elevator 10 and has a timer function in addition to a basic configuration such as a CPU and a memory. In the memory, for example, various control programs for performing drive control of the hoist 16 and opening / closing control of a car door (not shown) are stored. When the CPU reads out these programs from the memory and executes them, smooth operation of the elevator 10 by the control device 46 is realized.

  In the elevator 10 having the above configuration, control related to destination floor registration of the car 22 is also performed by the control device 46. A control program related to destination floor registration of the car 22 is stored in the memory of the control device 46. In the control device 46, the CPU reads out the control program from the memory and executes a series of determination / processing shown in FIG. 3 to control the destination floor registration of the car 22.

  Here, the control device 46 controls the destination floor registration of the car 22 based on the detection signal transmitted from the sensors 32A, 32B,... 32C of the car operation panel 28, but immediately upon receiving the detection signal. Instead of registering as a destination floor, a detection condition for detecting an operation for determining the destination floor is set. Specifically, while monitoring the duration of the detection signal with a timer, according to the situation, it is determined whether the duration has passed the first to third threshold times, and based on the result, the destination floor Is configured to control whether or not to register.

  Hereinafter, the control of the destination floor registration of the car 22 in the elevator 10 will be specifically described with reference to FIG. 3, taking as an example the case where the second floor is registered as the destination floor. It is assumed that the car 22 is currently on the 10th floor hall 26C (FIG. 1), which is the top floor, and the car door (not shown) is open.

  The control device 46 (CPU) first checks whether or not the second floor can be registered (S1). The state where the second floor cannot be registered includes, for example, a state where the elevator 10 is not operating, a state where the second floor is landed, a state where the second floor is already registered as the destination floor, and the like.

  When it is not in a state where the second floor can be registered (S1: NO), it waits until it becomes a state where the second floor can be registered. On the other hand, when the second floor can be registered (S1: YES), the presence or absence of a detection signal from the sensor 32B that detects an operation for determining the second floor as the destination floor is confirmed and adjacent to the sensor 32B. The presence or absence of a detection signal from the adjacent sensor is confirmed (S2).

  The “adjacent sensor” here refers to the sensor 32A corresponding to the first floor which is the adjacent floor of the second floor as the destination floor and the sensor corresponding to the third floor. In this example, there are two adjacent sensors. However, when the destination floor is the lowest floor (first floor) or the highest floor (10th floor), there is one adjacent sensor.

  When there is a detection signal from the sensor 32B and no detection signal from the adjacent sensor (S2: YES), it is determined whether the duration of the detection signal from the sensor 32B has passed the first threshold time. (S3). When the first threshold time elapses (S3: YES), the second floor is registered as the destination floor (S4). Specifically, the control device 46 turns on the destination floor registration flag on the second floor, and lights the number “2” displayed on the destination floor operation unit 30 of the car operation panel 28 and the separation line 37B corresponding thereto. And a process of outputting a simple registered sound from the speaker.

  On the other hand, when the duration of the detection signal from the sensor 32B has not passed the first threshold time (S3: NO), even if there is a detection signal from the sensor 32B, the second floor is registered as the destination floor. No transition is made to the standby state.

  The first threshold time described above is, for example, about 0.3 seconds. By setting the first threshold time in this manner, the elevator 10 causes the destination floor operation unit 30 of the car operation panel 28 to detect any object including a part of the passenger's body as a sensor 32A, 32B, ... 32C. This prevents accidental events such as grazing each detection area for a moment as an operation for determining the destination floor of the car 22.

  At this point, the second floor has already been registered as the destination floor. In the elevator 10, the control device 46 continues to monitor the detection signal from the sensor 32B and confirms whether the detection signal continues. (S5). If the detection signal from the sensor 32B is not continued (S5: NO), the determination / processing is ended there and the destination floor registration of the car 22 to the second floor is completed.

  On the other hand, when the detection signal from the sensor 32B continues (S5: YES), the control device 46 determines whether or not the second threshold time has passed after the first threshold time has passed (S6). . If the detection signal from the sensor 32B does not continue until the second threshold time elapses (S6: NO), it is confirmed after confirming that the detection signal is not continued again (S5: NO). The process is terminated and the destination floor registration to the second floor of the car 22 is completed.

  However, when the detection signal from the sensor 32B continues until the second threshold time elapses (S6: YES), the control device 46 cancels the already completed second floor destination floor registration (S4) ( S7). Specifically, the control device 46 turns off the numeral “2” displayed on the destination floor operation unit 30 of the car operation panel 28 and the separation line 37B corresponding thereto, and outputs a notification sound from the speaker. Alternatively, by displaying a notification image on the display unit 44, a process of notifying the passenger that the second floor destination floor registration is to be canceled is executed, and the second floor destination floor registration flag is returned from ON to OFF. When the destination floor registration on the second floor is cancelled, the control device 46 ends the determination / processing.

  The second threshold time described above is, for example, about 5 seconds. By setting such a second threshold time and incorporating a destination floor registration cancellation process, in the elevator 10, in the destination floor operation unit 30 of the car operation panel 28, for example, any of the sensors 32A, 32B,. One of them continues to detect a part of the passenger's body, baggage, etc., or the sensor itself malfunctions, so these events are falsely detected as operations for destination floor registration. Control that can prevent erroneous registration of a destination floor is realized.

  In addition, even if the already completed destination floor registration is canceled, the fact is notified to the passenger, so the passenger can be prompted to re-register the destination floor. For this reason, it is difficult for a passenger who uses the elevator 10 to be confused.

  By the way, in the above-described car operation panel 28, it is assumed that both the sensor 32B and the adjacent sensor simultaneously detect operations in the destination floor operation unit 30. At this time, in the control device 46, there is a detection signal from the sensor 32B and a detection signal from the adjacent sensor (S2: NO). In this case, the control device 46 confirms that there is a detection signal from the sensor 32B corresponding to the second floor serving as the destination floor (S8).

  At this time, if the detection signal from the sensor 32B cannot be confirmed (S8: NO), a transition is made to a standby state. On the other hand, if the detection signal from the sensor 32B can be confirmed (S8: YES), has the third threshold time elapsed since the detection signal from the sensor 32B and the detection signal from the adjacent sensor are also present? It is determined whether or not (S9).

  If this state (the state in which there is a detection signal from each of the sensor 32B and the adjacent sensor) does not continue until the third threshold time has elapsed (S9: NO), the state shifts to a standby state. On the other hand, when this state continues until the third threshold time elapses (S9: YES), the control device 46 warns that both the sensor 32B and the adjacent sensor detect an operation (S10). Specifically, the control device 46 executes a warning process such as outputting a warning sound from a speaker of the car operation panel 28 or displaying a warning image on the display unit 44. When the warning process is executed, the control device 46 ends the determination / process.

  The above-described third threshold time is, for example, about 3 seconds. By setting such a third threshold time for the duration of the state in which there is a detection signal from each of the sensor 32B and the adjacent sensor, the elevator 10 has a situation in which erroneous registration of the destination floor may occur. It can be recognized. For example, the passenger standing position or baggage in the car 22 is too close to the car operation panel 28, or the passenger leans against the car operation panel 28. And since the warning with respect to such a situation is made, the passenger can recognize that. As a result, not only will this situation be resolved, it will also help prevent recurrence.

  Moreover, in the elevator 10 of this embodiment, the said judgment in case both the sensor 32B and an adjacent sensor detect operation is performed at the timing until the 1st threshold time passes, and both sensors detected operation. In such a case, control that does not register the destination floor is adopted. Thereby, even if the said situation generate | occur | produces in the cage | basket | car 22, the erroneous registration of the destination floor which a passenger does not intend can be prevented reliably.

Second Embodiment
In the first embodiment, when the destination floor (second floor) is registered, only the detection signal from the sensor (sensor 32B) corresponding to the destination floor is monitored, and the presence or absence of the detection signal from the adjacent sensor is confirmed. The destination floor registration of the car 22 is to be controlled. On the other hand, in the elevator according to the second embodiment, not only the detection signal from the sensor (sensor 32B) corresponding to the destination floor but also the detection from the adjacent sensor after the destination floor (second floor) is registered. The car will continue to monitor the destination floor while controlling the destination floor registration.

  The basic configuration of the elevator according to the second embodiment is the same as that of the elevator 10 according to the first embodiment, except that the control related to the registration of the destination floor of the car is different. Therefore, the schematic configuration diagram of the elevator according to the second embodiment will refer to the elevator 10 shown in FIG. 1, and will be described below with the same reference numerals as the components of the elevator 10.

  In the elevator according to the second embodiment, the control until the destination floor of the car 22 is registered is substantially the same as that in the first embodiment. Therefore, regarding the control related to the destination floor registration of the elevator car 22 according to the second embodiment, the description of the control part common to the first embodiment will be made only when necessary with reference to FIG. A description will be given centering on a control part different from the first embodiment.

  As shown in FIG. 4, when the second floor is registered as the destination floor (S4), the control device 46 confirms whether or not the detection signal from the sensor 32B is continued as in the first embodiment (S5). If the detection signal from the sensor 32B is not continued (S5: NO), the determination / processing is ended there and the destination floor registration of the car 22 to the second floor is completed.

  On the other hand, when the detection signal from the sensor 32B continues (S5: YES), the control device 46 further confirms the presence or absence of the detection signal from the adjacent sensor (S11). If there is no detection signal from the adjacent sensor (S11: YES), the controller 46 determines whether or not the second threshold time has passed after the first threshold time has passed (S6).

  Here, when there is a detection signal from the adjacent sensor (S11: NO), the control device 46 determines that the duration of the state in which there is the detection signal from the sensor 32B and also the detection signal from the adjacent sensor is the third time. It is determined whether the threshold time has elapsed (S12). If this state does not continue until the third threshold time has elapsed (S12: NO), the controller 46 continues to monitor detection signals from the sensor 32B and the adjacent sensors.

  On the other hand, when this state continues until the third threshold time elapses (S12: YES), the control device 46 warns that both the sensor 32B and the adjacent sensor detect an operation (S10), The judgment / processing is terminated.

  As described above, in the second embodiment, even after the destination floor (second floor) is registered, the control device 46 monitors the detection signals from the sensor (sensor 32B) corresponding to the destination floor and the adjacent sensors. The system is configured to recognize the above-described situation where erroneous registration of the destination floor may occur and to issue a warning to the passengers.

  As mentioned above, although the elevator which concerns on this invention has been demonstrated based on embodiment, of course, this invention is not restricted to an above-described form, For example, you may implement with the following forms.

<Modification>
(1) In the above embodiment, each of the sensors 32A, 32B,... 32C for detecting the operation of determining the destination floor of the car 22 in a non-contact manner by the passenger in the destination floor operation section 30 of the car operation panel 28 is vertically oriented. However, it may be arranged in a horizontal row with a spacing in the horizontal direction. As such a car operation panel, for example, a sub-car operation panel installed at a height that can be easily operated by a passenger using a wheelchair can be cited.

  (2) In the above-described embodiment and modification, each of the non-contact sensors is arranged in a line at intervals, but these sensor lines may be arranged in two lines.

  For example, in the destination floor operation unit 50 shown in FIG. 5A, the first sensor array C1 including the sensors 52A, 52B,... 52C corresponding to the first to fifth floors and the sixth to tenth floors are supported. The second sensor row C2 including the sensors 52D, 52E,... 52F is arranged in parallel on the left and right. A non-contact type switching sensor 54 is provided above each of the first sensor array C1 and the second sensor array C2. Each time the switching sensor 54 detects a switching operation, the sensor column capable of detecting an operation for determining the destination floor is switched between the first sensor column C1 and the second sensor column C2. On the upper side of the switching sensor 54, a switching display unit 56 is provided. The switching display unit 56 includes left and right indicator lamps 56A and 56B, and there is an indicator lamp on the side having a sensor column that can detect an operation for determining a destination floor (in FIG. 5A, there is a first sensor column C1). The side indicator lamp 56A) is lit.

  Even in the configuration like the destination floor operation unit 50 described above, if the destination floor registration control on the first sensor column C1 side and the destination floor registration control on the second sensor column C2 side are performed independently, Similarly to the above embodiment, it is possible to control the destination floor registration on each of the first sensor column C1 side and the second sensor column C2 side. Note that even if the switching sensor 54 detects a sensor row switching operation, the already completed destination floor registration is not canceled.

  The destination floor operation unit 50 configured as described above is effective in preventing erroneous registration in the following scenes, for example. When the passenger who uses the elevator is right-handed, when operating the first sensor row C1 on the left side, the right arm portion of the passenger has sensors 52D, 52E,... 52F that constitute the second sensor row C2 on the right side. There is a possibility that the destination floor corresponding to the sensor is erroneously registered. However, the destination floor operation unit 50 operates the first sensor column C1 on the left side in a state where each sensor 52D, 52E,... 52F of the second sensor column C2 on the right side is invalid (undetectable). Therefore, erroneous registration on the second sensor column C2 side does not occur.

  Alternatively, in the destination floor operation unit 60 shown in FIG. 5B, the third sensor row C3 including the sensors 62A, 62B,... 62C corresponding to the odd floors and the sensors 62D, 62E,. Each of the fourth sensor rows C4 is arranged in parallel on the left and right sides with different heights between the adjacent sensors on the left and right. Therefore, the sensors 62A,... 62F corresponding to the floors are alternately arranged in a staggered pattern on the left and right.

  In the destination floor operation unit 60 described above, for example, when registering the second floor as the destination floor, the sensor 62A corresponding to the first floor and the sensor 62B corresponding to the third floor, which are adjacent to the second floor as the destination floor, and Three sensors of the sensor 62E corresponding to the fourth floor arranged adjacent to the sensor 62D corresponding to the second floor are “adjacent sensors”. When the third floor is registered as the destination floor, the sensor 62D corresponding to the second floor, which is the adjacent floor of the third floor serving as the destination floor, the sensor 62E corresponding to the fourth floor, and the sensor 62B corresponding to the third floor. The four sensors, the sensor 62A corresponding to the first floor and the sensor corresponding to the fifth floor, which are arranged adjacent to each other, are “adjacent sensors”. As described above, in the above-described destination floor operation unit 60, the number of adjacent sensors whose detection signals should be monitored increases, but it is possible to control destination floor registration as in the above embodiment.

  The destination floor operation unit 60 having the above-described configuration is arranged in a zigzag pattern by arranging the sensors 62A,... 62F corresponding to the respective floors, as compared with the above-described destination floor operation unit 50 (FIG. 5A). The distance between the left and right sensors is wide. As a result, the possibility that the left and right sensors detect the operation at the same time is reduced, and as a result, the occurrence of erroneous registration can be reduced as much as possible without providing the switching sensor 54. Further, since no other sensor is arranged directly beside each sensor 62A,... 62F, it is possible to prevent the occurrence of erroneous registration due to the above-described scene, that is, the dominant arm of the passenger as much as possible.

  (3) In the above embodiment, the car operation panel 28 installed in the car 22 is a non-contact type, but is installed in each of the landings 26A, 26B, 26C (FIG. 1) provided on different floors. The hall operation panel (not shown) may be a non-contact type.

  The hall operation panel is usually provided with a call button. The call buttons include an upper call button and a lower call button, which are generally arranged adjacent to each other in the vertical direction or the left and right directions. The call registration operation by the upper call button or the lower call button is detected in a non-contact manner by the upper call sensor or the lower call sensor.

  In this case, for example, when registering an upper call, the upper call sensor is a destination floor sensor and the lower call sensor is an adjacent sensor. On the other hand, when registering a lower call, the lower call sensor becomes a destination floor sensor and the upper call sensor becomes an adjacent sensor. Regardless of which call registration operation is performed with any sensor, the operation is an operation of determining the destination floor of the car 22 moving on the hoistway 12 as the floor of the landing where the landing operation panel is installed. There is no change.

  In addition, as long as it is an operation panel for performing destination floor registration, it may be applied not only to the landing operation panel but also to an operation panel installed at a place away from the landing such as a building entrance or a passage. Absent.

  (4) In the above embodiment, there is one car operation panel 28 installed in the car 22, but a plurality of car operation panels may be installed in the car. In this case, by controlling the destination floor registration on each car operation panel independently of each other, it is possible to control the destination floor registration of the car as in the above embodiment.
