  According to the elevator voice destination floor registration device according to the present invention, the registration means registers only the destination floor first recognized by the voice recognition means among the destination floor instructions by the voice uttered by the passenger. It is possible to prevent the destination floor registration for minutes.

  In addition, the elevator voice destination floor registration device according to the present invention enables destination floor voice registration when only one passenger has entered the car, so only when the destination floor voice registration function is really needed. Can effectively exhibit the anti-tampering effect.

  Embodiments according to the present invention will be described below in detail with reference to the accompanying drawings. In this description, specific shapes, materials, numerical values, directions, and the like are examples for facilitating the understanding of the present invention, and can be appropriately changed according to the application, purpose, specification, and the like.

  FIG. 1 is a schematic configuration diagram showing an elevator car 12 including an elevator voice destination floor registration device 10 according to an embodiment of the present invention. Three ropes 14 are connected to the upper part of the car 12 arranged in the hoistway. When these ropes 14 are wound up or down by a hoisting machine (not shown), the car 12 moves up and down in the hoistway.

  An in-car scale device 16 that measures the weight of passengers in the car 12 is installed on the car 12. When the passenger weight measured by the car scale device 16 exceeds the total number of passengers by multiplying the preset number of passengers by the weight of about 65 kg per adult, a warning sound for overriding by a buzzer will sound in the car 12 It is supposed to be. In addition, the car scale device 16 constitutes a detecting unit that detects that the number of passengers in the car 12 is one, together with a control unit described later.

  A control device 18 is further installed on the car 12. The control device 18 has a function for controlling the elevator voice destination floor registration device 10. The control device 18 may be incorporated in an elevator control panel (not shown) that controls the entire elevator system.

  A front door in the car 12 is provided with a double-open or single-open car door 20 that opens the door when the car 12 reaches each floor and opens the car 12. A car operation panel 22 is installed on a car side wall located next to the car door 20 in the car 12. The car operation panel 22 includes a maintenance switch storage unit 24, a door opening / closing button 26, a destination floor registration button 28, an emergency intercom 30 and a floor indicator 32 in order from the bottom. A plurality of destination floor registration buttons 28 corresponding to the number of floors at which the car 12 stops are provided. In normal times, a destination floor is registered by a passenger entering the car 12 pressing a destination floor registration button on the destination floor. The button that was pressed to display the registration status is lit.

  On the side wall of the car located above the car operation panel 22, a microphone 34 constituting a part of the voice recognition means and a display 36 constituting the notification means are installed. The indicator 36 is for notifying the passengers in the car 12 that the destination floor voice registration is possible, and is illuminated with a lamp or the like so that “the destination floor can be registered by voice. "Is displayed. The indicator 36 may be of any type such as a lamp type, a liquid crystal, and an organic EL as long as it can display a message for the passenger.

  FIG. 2 is a block diagram showing a control system of the elevator voice destination floor registration device 10. The control device 18 includes a voice recognition unit 38 that constitutes a voice recognition unit together with the microphone 34, and a control unit 40 that constitutes a registration unit. The voice recognition unit 38 has a function of receiving and recognizing a destination floor instruction by a voice uttered by a passenger input via the microphone 34. Specifically, the voice recognition unit 38 stores a plurality of voice data corresponding to the number of floors in advance, and indicates destination floor instructions by collating these voice data with voice data input from the microphone 34. It can be recognized.

  The control unit 40 includes a CPU 42 that executes a control program, a ROM 44 that stores the control program, and a RAM 46 that stores, in a readable and writable manner, weight threshold data for determining whether or not there is one passenger. The The control unit 40 constitutes a part of detection means for detecting that the number of passengers in the car 12 is one, and only the destination floor recognized first among the destination floor instructions recognized by the voice recognition unit 38. Has the function of registering.

  In the elevator system to which the elevator voice destination floor registration device 10 of the present embodiment is applied, a voice car call registration device is installed at the landing of each floor, and this voice car call registration device is described in the background section above. As described above, conventionally known ones can be used.

  Next, functions of the elevator voice destination floor registration device 10 having the above-described configuration will be described. In this case, as shown in FIG. 1, a person who cannot carry out the car call operation at the landing and the destination floor registration operation in the car without first taking the baggage down to the floor is held by the passenger of the elevator. Description will be made assuming that the number is 1.

  For example, the passenger 1 who has arrived at the landing utters “up” or “done” to perform car call registration by voice, and the car call push button installed on the landing wall lights up. When the car 12 arrives at the floor where the passenger 1 waits, the car door 20 and the landing door (not shown) are opened to allow the passenger 1 to get into the car 12.

  At this time, the control unit 40 of the control device 18 executes the control as shown in FIG. First, when the passenger 1 gets into the car 12, it is determined whether or not the car passenger weight W measured by the car scale device 16 is less than 130 kg (step S10). The weight threshold of 130 kg here corresponds to twice the weight of 65 kg per adult, which is conventionally used as a standard for the number of elevator cars, that is, equivalent to two adults. However, this weight threshold value is merely an example, and can be set by changing to another numerical value suitable for detecting that there is one passenger.

  If it is determined that the passenger weight W in the car is less than 130 kg (YES in step S10), it is detected that the number of passengers is one. In this case, the microphone 34 and the voice recognition unit 38 in the car 12 are operated so that a voice destination floor instruction by the passenger 1 can be accepted, and the voice destination floor registration can be performed by turning on the display 36. (Step S12). This makes it possible for only one passenger 1 to recognize that the elevator system can perform voice destination floor registration. It should be noted that a voice announcement having the same content as the display by the display 36 may be made in the car 12 instead of or in combination with the notification by turning on the display 36.

  On the other hand, when the passenger weight W in the car is 130 kg or more (NO in step S10), it is detected that there are two or more passengers in the car 12, and the control flow is finished as it is.

  In addition, even if the number of passengers is two or more, such as one adult, one child, two women, three children, etc., the passenger weight in the car may be less than 130 kg. In this case, there is no problem because the destination floor registration is possible without using the voice by pressing the destination floor registration button 28 on the car operation panel 22 as usual.

  For example, the microphone 34 and the voice recognition unit 38 maintain a state in which a destination floor instruction can be received by voice until the door closing operation is started, for example. During this time, when the passenger 1 gives a voice to the destination floor such as “san” or “sankai” (YES in step S13), the third floor recognized by the voice recognition unit 38 is automatically registered as the destination floor, The pushbutton 28 for the third floor of the car operation panel 22 is turned on. At this time, even if the passenger 1 is mischievous, for example, “San, Yon, Go, Roku”, the destination floors of a plurality of floors are called by mischief, only the third floor first recognized by the voice recognition unit 38 is (Step S14). As a result, it is possible to prevent destination floor registration for a plurality of floors from being mischievous.

  When the registration of the destination floor by voice is completed, the display 36 is turned off (step S16), and the control flow ends. Similarly, when there is no voice destination floor instruction before the door closing operation is started (NO in step S13), the display 36 is similarly turned off (step S16), and the control flow is ended.

  As described above, according to the elevator voice destination floor registration device 10 of this embodiment, in order to register only the destination floor first recognized by the voice recognition unit 38 in the destination floor instruction by the voice uttered by the passenger 1, It is possible to prevent destination floor registration for multiple floors due to mischief.

  In addition, since the destination floor voice registration is enabled only when it is detected that only one passenger has entered the car 12, the destination floor voice registration function is effective only when it is really needed. This also improves the effect of preventing tampering.

  Furthermore, since the car scale device 16 normally installed in the car 12 is used to detect that the number of passengers in the car is one, a special sensor or camera for detecting the number of passengers is used. Cost can be suppressed compared with the case where it provides.
