Fig. 1 is a schematic view of the structure of a non-contact elevator. As shown in fig. 1, the contactless elevator includes an elevator control system 10, a drive motor 20, and a plurality of contactless hall-call panels 30. The non-contact hall call panels 30 are provided in plural numbers, respectively, in the vicinity of the elevator hatchway of each floor, and are connected to the elevator control system 10 through a bus. The elevator control system 10 is connected to a drive motor 20 for controlling the raising, lowering, and stopping positions of the car and the like by controlling the rotation speed, the rotation direction, and the like of the drive motor 20. When a user needs to take an elevator, a call command is input through the non-contact type hall call panel 30, and the elevator control system 10 enables the car to respond to the call command by controlling the operation of the driving motor 20.

Fig. 2 is a schematic circuit diagram of the contactless outbound panel 30, and fig. 3 is a schematic structural diagram of the contactless outbound panel 30. As shown in fig. 2 and 3, the contactless outbound panel 30 includes a mounting board 35, an elevator control display board 32, and two contactless keys and a control circuit 31. One of the non-contact keys is an up key 33, and the other is a down key 34. In some floors, the contactless outbound panel 30 may also have only the up button 33 or only the down button 34.

The mounting plate 35 is generally flat and is typically mounted to the landing gear attachment for carrying other components of the non-contact hall panel 30. The elevator control display panel 32, which may be an LED display panel, an LCD display panel, or another type of display panel 337, is disposed on the mounting plate 35 for displaying information about the car of the elevator. The control circuit 31 is connected to the ladder control display panel 32, the up button 33 and the down button 34. In this embodiment, the control circuit 31 includes a controller 311 and a watchdog circuit 312. The Controller 311 is used to execute written computer code, including but not limited to a Central Processing Unit (CPU), a Micro Control Unit (MCU), and other devices for interpreting computer instructions and Processing data in computer software. The elevator control display panel 32 is connected to the controller 311 for displaying information related to the elevator. The watchdog circuit 312 is essentially a timer circuit including an input coupled to the controller 311 and an output coupled to a reset of another controller 311. The function of the watchdog circuit 312 is to periodically monitor the operation of the controller 311 and to issue a restart signal to the controller 311 in the event of an error.

The up button 33 and down button 34 are of the same construction, with the difference that the up button 33 triggers an up call command and the down button 34 triggers a down call command. The structure and function of the non-contact elevator key will be described in detail below by taking the upper key 33 as an example. As shown in fig. 3, the up button 33 includes a panel 337, a button housing 336, and a circuit board 333. The panel 337 has a generally disc shape and is provided with one or more markings 3371 on its outer side to identify the function of the non-contact key. For example, for up button 33, the designation 3371 of panel 337 may be the upward arrow shown in FIG. 3; for the down key 34, the designation 3371 of the panel 337 may be a downward arrow. In addition, a region of the panel 337 is provided with a light-transmitting portion 3372 that transmits at least some of the light.

The key shell 336 is annular, the inner side of one end surface of the key shell 336 is provided with threads for being connected to the mounting plate 35 through the threads, and the other end surface (relative to the end surface of the mounting plate 35) is provided with a necking so that the cross section of the end surface is gradually reduced along the direction away from the mounting plate 35. Thus, the face plate 337 can be embedded in the other end surface of the key casing 336 and form a closed cavity with the key casing 336 and the mounting plate 35.

The circuit board 333 is substantially flat and disposed in a closed cavity formed by the face plate 337, the key case 336, and the mounting plate 35, and is parallel to the face plate 337. The circuit board 333 may be a printed circuit board 333, a flexible circuit board 333, or the like, to which electronic components are connected, and between which signals are transferred or power is supplied through conductive metal connections. In this embodiment, the circuit board 333 is provided with a two-in-one sensor 334, a key switch 332, and four light emitters 335. The two-in-one sensor 334 integrates an infrared proximity sensor 331 and an ambient light sensor (not shown in the figure). The infrared proximity sensor 331 transmits light through the light-transmitting portion 3372 of the panel 337 to be triggered by a detection object. In some embodiments, the infrared proximity sensor 331 can perform object detection in the range of 100mm, and the proximity detection function works well from bright to dark environments. The ambient light sensor preferably uses a dual photodiode to approximate the human visual response of low lumen performance under 0.01lux illumination for detecting ambient light brightness, providing high sensitivity detection capability, allowing the two-in-one sensor 334 to operate behind the dark light-transmissive portion 3372, such that the light-transmissive portion 3372 is barely visible, improving the aesthetics of the panel 337.

The key switch 332 is also called a light touch key switch or a light touch switch, and when the switch is used, the switch is closed and switched on by applying pressure to the switch operation direction under the condition of meeting the operation force, and when the pressure is relieved, the switch is switched off, and the internal structure of the switch is switched on and off by the stress change of the metal elastic sheet. The pins of the key switch 332 are connected to the circuit board 333 and face the panel 337, and when the panel 337 is pressed by a force, the pins contact the key switch 332 to trigger the key switch 332. The light emitter 335 is preferably an LED (light emitting diode) that illuminates the indicator 3371 of the panel 337 when the infrared proximity sensor 331 or the key switch 332 is activated. In this embodiment, in order to prevent erroneous determination, when the up button 33 and the down button 34 are simultaneously activated, the control circuit 31 may determine that an up command is issued to the elevator control system 10. In the present embodiment, since the key switch 332 and the infrared proximity sensor 331 are connected to the controller 311 in parallel in the up key 33 or the down key 34, one of the key switch 332 and the infrared proximity sensor 331 of the up key 33 is triggered, that is, an up command is triggered. Similarly, one of the key switches and the infrared proximity sensor of the down key 34 is activated to trigger the down command.

The non-contact elevator key can simply replace the operation key (the up key 33 or the down key 34) of the original elevator without changing the structure of the original outbound panel. During installation, the key case 336 of the original operation key is opened, the elevator key is removed, and the connecting wire originally connected to the elevator key is connected to the control circuit 31.

When the device is used, a user can suspend in the air within 5cm of the panel 337 to perform induction triggering or gesture triggering key instruction on the non-contact type outbound panel 30. When the finger is close to the call panel 337 and reaches the preset distance, the infrared proximity sensor 331 judges the user's operation intention by monitoring the external brightness and the signal of human infrared reflection in real time, and the pixels of the sensor internal array can intelligently identify some actions such as the air-spaced super-doing and gesture operation of the user, and avoid the bacterial infection brought by the direct contact of the personnel with the keys.

The non-contact type outbound panel 30 and the elevator are characterized in that the transparent part 3372 is arranged on the panel 337 of the non-contact type press key of the non-contact type outbound panel 30, the infrared proximity sensor 331 is arranged on the circuit board 333, so that light emitted by the infrared proximity sensor 331 can be triggered by a detected object through the transparent part 3372 of the panel 337, and thus a user can trigger the non-contact type press key to give a call command when an object such as a finger is close to the non-contact type press key, non-contact elevator riding is realized, and the probability of cross infection of germs is reduced.

Further, the above-mentioned non-contact call-out panel 30 and the elevator also have a key switch 332, so that the user can also touch the key switch 332 to activate the up key 33 or the down key 34 by touch operation. And the non-contact key is simple to install, can be transformed based on the existing elevator system, is plug-and-play, and can be added with a non-contact operation function through simple operation.
