[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention, and the embodiments described are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] In the various embodiments of the present invention, for the convenience of description and not to limit the present invention, the term "connection" used in the patent application specification and claims of the present invention is not limited to physical or mechanical connection, but may include electrical connection, whether direct or indirect. "Up", "down", "below", "left", "right", etc. are only used to indicate relative position relationship. When the absolute position of the described object changes, the relative position relationship also changes accordingly.

[0029] Figure 1 It is a schematic diagram of the structure of a contactless elevator. Figure 1 As shown, the contactless elevator includes an elevator control system 10, a drive motor 20 and a plurality of contactless outbound call panels 30. There are a plurality of contactless outbound call panels 30, which are respectively arranged near the elevator entrance of each floor and connected to the elevator control system 10 through a bus. The elevator control system 10 is connected to the drive motor 20, and is used to control the rise, descent and parking position of the car by controlling the speed and direction of the drive motor 20. When a user needs to take the elevator, the call command is input through the contactless outbound call panel 30, and the elevator control system 10 controls the operation of the drive motor 20 so that the car can respond to the call command.

[0030] Figure 2 is a schematic diagram of the circuit structure of the contactless outbound call panel 30, Figure 3 Schematic diagram of the structure of the contactless outbound call panel 30. Figure 2 and Figure 3As shown, the contactless outbound call panel 30 includes a mounting plate 35, a ladder control display panel 32, two contactless buttons and a control circuit 31. Among them, one contactless button is an up button 33, and the other is a down button 34. On some floors, the contactless outbound call panel 30 may also have only an up button 33 or only a down button 34.

[0031] The mounting plate 35 is generally in the shape of a flat plate, and is generally installed near the elevator entrance, and is used to carry other components of the non-contact outbound call panel 30. The elevator control display panel 32 can be an LED display panel, an LCD display panel or other types of display panels 337, which are arranged on the mounting plate 35 to display the relevant information of the elevator car. The control circuit 31 is connected to the elevator 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 the written computer code, including but not limited to a processor (Central Processing Unit, CPU), a microcontroller unit (Micro Controller 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 to display the relevant information of the elevator. The watchdog circuit 312 is essentially a timer circuit, including an input end and an output end, wherein the input end is connected to the controller 311, and the output end is generally connected to the reset end of another controller 311. The function of the watchdog circuit 312 is to regularly monitor the working condition of the controller 311 and send a restart signal to the controller 311 once an error occurs.

[0032] The structures of the up button 33 and the down button 34 are the same, except that the up button 33 triggers an up call, while the down button 34 triggers a down call. The structure and function of the contactless elevator button are described in detail below, taking the up button 33 as an example. Figure 3 As shown, the up button 33 includes a panel 337, a button shell 336 and a circuit board 333. The panel 337 is generally in the shape of a disc, and one or more marks 3371 are arranged on the outside to identify the function of the non-contact button. For example, for the up button 33, the mark 3371 of the panel 337 can be Figure 3 for the down button 34, the mark 3371 of the panel 337 may be a downward arrow. In addition, a region of the panel 337 is further provided with a light-transmitting portion 3372, which can transmit at least part of the light.

[0033] The button shell 336 is in a circular shape, and a thread is provided on the inner side of one end surface of the button shell 336 for connecting to the mounting plate 35 through the thread, and a constriction is provided on the other end surface (the end surface relative to the mounting plate 35) so that the cross section of the end surface gradually decreases in the direction away from the mounting plate 35. In this way, the panel 337 can be embedded in the other end surface of the button shell 336 and form a closed cavity with the button shell 336 and the mounting plate 35.

[0034] The circuit board 333 is generally in the shape of a plate, and is arranged in a closed cavity formed by the panel 337, the button shell 336, and the mounting plate 35, and is parallel to the panel 337. The circuit board 333 can be a printed circuit board 333, a flexible circuit board 333, etc., on which electronic components are connected, and the electronic components are connected by conductive metal to transmit signals or power. In this embodiment, the circuit board 333 is provided with a two-in-one sensor 334, a button switch 332 and four light emitters 335. The two-in-one sensor 334 integrates an infrared proximity sensor 331 and an ambient brightness 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 the detected object. In some embodiments, the infrared proximity sensor 331 can detect objects within a range of 100 mm, and the proximity detection function can work well in environments from bright to dark. The ambient brightness sensor preferably uses a dual photodiode to approximate the human eye's visual response to low lumen performance under an illumination of 0.01 lux, and is used to detect the ambient light brightness, providing a high-sensitivity detection capability, so that the two-in-one sensor 334 can operate behind the dark light-transmitting portion 3372, so that the light-transmitting portion 3372 is almost invisible, thereby improving the aesthetics of the panel 337.

[0035] The key switch 332 is also called a touch key switch or a touch switch. When in use, the switch function is closed and connected by applying pressure in the switch operation direction under the condition of the operating force. When the pressure is removed, the switch is disconnected. Its internal structure relies on the change of the force of the metal spring to achieve on and off. The pin of the key switch 332 is connected to the circuit board 333 and faces the panel 337. When the panel 337 is pressed by force, it contacts the key switch 332 to trigger the key switch 332. The light emitter 335 is preferably an LED (light emitting diode), which lights up the mark 3371 of the panel 337 when the infrared proximity sensor 331 or the key switch 332 is triggered. In this embodiment, in order to prevent misjudgment, when the up button 33 and the down button 34 are triggered at the same time, the control circuit 31 can be judged as sending an up command to the elevator control system 10. In this embodiment, for the up button 33 or the down button 34, the button switch 332 and the infrared proximity sensor 331 are connected in parallel to the controller 311, so that when one of the button switch 332 and the infrared proximity sensor 331 of the up button 33 is triggered, the up instruction is triggered. Similarly, when one of the button switch and the infrared proximity sensor of the down button 34 is triggered, the down instruction is triggered.

[0036] The above-mentioned non-contact elevator button can simply replace the original elevator operation button (up button 33 or down button 34) without changing the structure of the original outbound call panel. During installation, the button shell 336 of the original operation button is opened, the elevator button is removed, and the connection line originally connected to the elevator button is connected to the control circuit 31.

[0037] When in use, the user can hover within 5cm of the panel 337 to perform induction triggering or gesture triggering of the non-contact outbound call panel 30. When the finger approaches the elevator call panel 337 to a preset distance, the infrared proximity sensor 331 determines the user's operation intention by real-time monitoring of the external brightness and the infrared reflection signal of the human body, and the pixels in the array inside the sensor can intelligently identify the user's remote operation and gesture operation and other actions to avoid bacterial infection caused by direct contact with the buttons.

[0038] The above-mentioned contactless outbound call panel 30 and elevator are configured with a light-transmitting portion 3372 on the panel 337 of the contactless button of the contactless outbound call panel 30, and an infrared proximity sensor 331 on the circuit board 333, so that the light emitted by the infrared proximity sensor 331 can be transmitted through the light-transmitting portion 3372 of the panel 337 to be triggered by the detected object. In this way, the user can use an object such as a finger to trigger the contactless button to issue an elevator call command when approaching the contactless button, thereby realizing contactless elevator riding and reducing the chance of cross-infection of germs.

[0039] Furthermore, the non-contact outbound call panel 30 and the elevator also retain a key switch 332, so that the user can also touch the key switch 332 to trigger the up button 33 or the down button 34. Moreover, the non-contact key is easy to install and can be modified based on the existing elevator system, plug and play, and a non-contact operation function can be added with simple operation.
