Description

Technical Field

[0001] This utility model relates to the field of elevator equipment, and in particular to a split-type elevator external call device. Background Technology

[0002] With the acceleration of urbanization and the increasing number of high-rise buildings, elevators have become an indispensable means of transportation in people's daily lives. Elevator external call systems, as an important component of the elevator system, allow passengers to conveniently select their desired floors and send commands to the elevator control system from outside the elevator. Traditional elevator external call systems mainly use contact-based operation methods such as buttons or touchscreens. However, existing contact-based operation methods for elevator external call systems have several problems. First, buttons and touchscreens are easily contaminated and damaged, requiring regular cleaning and maintenance, increasing usage costs and maintenance difficulty. Second, during special periods such as pandemics, contact-based operation methods pose a risk of cross-infection, which is detrimental to the health and safety of passengers.

[0003] Existing patent CN111362083B discloses a contactless external call panel and an elevator. This contactless external call panel includes a mounting plate and a contactless button connected to the mounting plate. The contactless button includes: a panel with a light-transmitting portion; and a circuit board with an infrared proximity sensor. The infrared proximity sensor transmits light through the light-transmitting portion of the panel to be triggered by a detected object. This contactless external call panel and elevator, by providing a light-transmitting portion to the contactless button's panel and an infrared proximity sensor on the circuit board, allows light emitted by the infrared proximity sensor to be transmitted through the light-transmitting portion of the panel to be triggered by a detected object. This allows users to trigger the contactless button by bringing an object such as a finger near it to issue an elevator call command, achieving contactless elevator access and reducing the chance of cross-infection of germs.

[0004] Existing contactless call devices are often in the form of panels. However, elevator call devices in commercial elevators, large home elevators, or villa elevators may need to be integrated with large figurines or sculptures to enhance the overall aesthetics of the interior design. Furthermore, existing panel-type contactless call devices lack means to optimize the user experience through intelligent voice interaction and personalized services. In addition, in application scenarios such as hotel lobbies, to prevent unauthorized access, elevators often require designated operators to use access cards or other authentication methods to make calls. These operators cannot always remain at the elevator door to operate the elevator; therefore, a remote elevator call device is needed for convenient operation. Utility Model Content

[0005] Existing elevator call panels fail to enhance the aesthetics of the overall interior layout and lack means to optimize the user experience through intelligent voice interaction and personalized services. They also lack both contact and contactless call methods and the means to remotely call the elevator.

[0006] To address the aforementioned technical problems, the present invention provides the following technical solution: a split-type elevator external call device, installed in an external ornament independent of the elevator, including a signal conversion board wirelessly connected to the elevator control circuit. The signal conversion board is connected to an external call sensing module, a feedback buzzer, and a signal feedback light. The external call sensing module includes a touch sensor, a contactless sensing module, and an access control module. The external ornament includes, but is not limited to, large figurines, sculptures, and other large decorative items. Large figurines are generally half-body height, i.e., three-dimensional collectible models approximately 1m-1.5m in size. Using large figurines as the carrier of the elevator external call device can increase aesthetics and enhance the user experience.

[0007] Specifically, the outbound call sensing module includes a main control chip, which is connected to a touch sensor and a contactless sensing module. The touch sensor determines touch actions through capacitive sensing, and the main control chip samples the capacitance change signal in real time. When a touch action is detected, it transmits the communication signal to the signal conversion board.

[0008] Specifically, the contactless sensing module includes a distance sensor and a touchless sensor. When powered on, it generates an alternating magnetic field. When a metal object and a human body approach each other, the resulting eddy currents generate a reverse magnetic field. This reverse magnetic field changes the inductance value of the induction coil inside the distance sensor.

[0009] Specifically, changes in the inductance of the induction coil inside the distance sensor affect the frequency and amplitude of the oscillation circuit inside the touchless sensor; the detection circuit of the main control chip amplifies the signal change of the oscillation circuit through the amplification circuit, and transmits the communication signal to the signal conversion board when an effective change in inductance is detected.

[0010] Specifically, the outbound call sensor module also includes an access control module. This module authenticates the user using fingerprints or access cards. Once authentication is complete, it can force external control of the elevator in special circumstances. After authentication, the outbound call device has higher-level control over the elevator system, enabling functions such as forcibly starting or stopping the elevator. This is used to force elevator control in special situations or accidents, such as fires, earthquakes, children trapped in the elevator, or accidental activation of the emergency stop button. In these situations, after authentication, the outbound call device can force the elevator to stop and open the doors.

[0011] Specifically, the signal conversion board can also be wired to the elevator control circuit. After receiving the paging signal from the external call sensor module, the signal conversion board decodes the encrypted shaft signal in the elevator control cable and converts it into a plaintext indication signal. It then analyzes and processes these indication signals to generate a specific floor command, which is transmitted to the elevator control circuit to complete the elevator paging process. The elevator paging will then summon the elevator to the user's floor. After entering the elevator, the user can control the elevator to go to the desired floor using buttons or voice commands inside the elevator.

[0012] Specifically, after receiving the paging signal from the outbound call sensor module, the signal conversion board controls the buzzer to turn on and triggers the buzzer to sound.

[0013] Specifically, the control signal feedback light illuminates after the signal conversion board receives the paging signal from the outbound call sensor module, and turns off after the elevator arrives at the station.

[0014] Specifically, the elevator control circuit has an elevator call module inside. After receiving a specific floor command generated by the signal conversion board, the elevator call module will call the elevator to the designated floor.

[0015] Specifically, the signal conversion board, outbound call sensor module, feedback buzzer, and signal feedback light are separately and independently installed in different parts of the external ornament.

[0016] The beneficial effects of this utility model are: 1. Improved efficiency: The contactless outbound calling can automatically dial and interact with voice, which greatly improves the efficiency of outbound calling and reduces the time and cost of manual operation; at the same time, the outbound calling device can be wirelessly connected to the elevator control system, and remote operation can facilitate the use of elevator operators.

[0017] 2. Increased reach: Compared to traditional manual outbound calling, contactless outbound calling can reach more potential customers more quickly, increasing reach and sales opportunities;

[0018] 3. Enhance customer experience: Through intelligent voice interaction and personalized services, contactless outbound calling can provide a more convenient and efficient customer experience, enhancing customer satisfaction and loyalty;

[0019] 4. Risk Reduction: During special periods such as the pandemic, contactless outbound calling can avoid direct contact between people, reduce the risk of transmission, and protect the health and safety of employees and customers; at the same time, the identity authentication of the access control module, and the high-level emergency control of the elevator after authentication, can ensure the safety of elevator users in special circumstances.

[0021] Figure 2This is a schematic diagram of the internal structure of this utility model.

[0022] In the diagram, 1 is the elevator control circuit, 2 is the signal conversion board, 3.1 is the touch sensor, 3.2 is the distance sensor, 3.3 is the non-touch sensor, 4 is the feedback buzzer, 5 is the signal feedback light, and 6 is the elevator call module. Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Example 1: As Figure 2 As shown, this embodiment provides a split-type elevator call device, including a signal conversion board 2 connected to the elevator control circuit 1. The signal conversion board 2 is connected to a call sensor module, a feedback buzzer 4, and a signal feedback light 5. The call sensor module, feedback buzzer 4, and signal feedback light 5 are respectively placed on different parts of a large figurine. The call sensor module can sense the user's touch to call the elevator, or it can sense the user's non-contact outstretched hand to call the elevator. After detecting the user's elevator call action, the signal conversion board 2 sends a specific floor command to the elevator control circuit 1, calling the elevator to the user's floor. Large figurines are generally half-body height, i.e., three-dimensional collectible models of about 1m-1.5m in size. Using large figurines as the carrier of the elevator call device can increase the aesthetics and enhance the user experience.

[0025] like Figure 1 As shown, the outbound call sensing module includes a main control chip, which connects to a touch sensor 3.1 and a contactless sensing module. The touch sensor 3.1 detects touch actions through capacitive sensing. The main control chip samples the capacitance change signal in real time and transmits the communication signal to the signal conversion board 2 when a touch action is detected. The sensing electrodes on the internal circuit board of the touch sensor 3.1 form a capacitive circuit with the human body. The electrical characteristics of the human body change the capacitance value of the sensing electrodes. The main control chip samples the capacitance change signal in real time through its internal analog-to-digital converter (ADC) module, analyzes and judges the touch action (such as touching or swiping) based on the capacitance change, triggers the internal logic circuit, and finally drives the switching execution circuit (such as a MOSFET) to achieve on / off control.

[0026] The contactless sensing module includes a distance sensor 3.2 and a touchless sensor 3.3. When powered on, it generates an alternating magnetic field. When a metal object and a human body approach each other, the resulting eddy currents generate a reverse magnetic field. The reverse magnetic field changes the inductance value of the induction coil inside the distance sensor 3.2.

[0027] The change in inductance of the induction coil inside the distance sensor 3.2 will affect the frequency and amplitude of the oscillation circuit inside the non-touch sensor 3.3; the detection circuit of the main control chip amplifies the signal change of the oscillation circuit through the amplification circuit, and transmits the communication signal to the signal conversion board 2 when an effective change in inductance is detected.

[0028] The distance sensor 3.2 and the non-touch sensor 3.3 generate an alternating magnetic field when powered on. When a metal object or human body approaches the magnetic field area, eddy currents are generated inside the metal. The reverse magnetic field generated by these eddy currents changes the inductance value of the induction coil. This change in inductance value affects the frequency or amplitude of the oscillation circuit containing the coil. The main control chip captures this changing signal in real time through the detection circuit, oscillation circuit, and amplification circuit. After amplification and filtering, it analyzes and determines whether an object is approaching. After the non-touch sensor 3.3 receives the signal, the main control chip detects the effective inductance change. After matching the preset command, it drives the back-end execution circuit to switch the thyristor, changing the circuit state and realizing the circuit switching, thus completing the non-touch triggered switch control.

[0029] After receiving the paging signal from the external call sensor module, the signal conversion board 2 decodes the encrypted shaft signal in the elevator control cable and converts it into a plain text indication signal. Then, it analyzes and processes these indication signals and generates a specific floor instruction to be transmitted to the elevator control circuit 1 to complete the elevator paging process.

[0030] After receiving the paging signal from the outbound call sensor module, the signal conversion board 2 controls the buzzer to turn on and triggers the buzzer to sound.

[0031] After the signal conversion board 2 receives the paging signal from the outbound call sensor module, the control signal feedback light 5 lights up. After the elevator arrives at the station, the control signal feedback light 5 turns off.

[0032] Example 2: This example provides a split-type elevator call device, including a signal conversion board 2 connected to the elevator control circuit 1. The signal conversion board 2 is connected to the call sensor module, the feedback buzzer 4, and the signal feedback light 5, respectively. The call sensor module, the feedback buzzer 4, and the signal feedback light 5 are placed in different parts of a large collectible figure. Large collectible figures are generally half-body height, i.e., three-dimensional collectible models about 1m-1.5m in size. Using large collectible figures as the carrier of the elevator call device can increase aesthetics and enhance the user experience.

[0033] The external call sensor module can detect a user's touch to make an elevator call, or it can detect a user's non-contact hand gesture to make an elevator call. After detecting the user's elevator call action, the signal conversion board 2 sends a specific floor command to the elevator control circuit 1, which then calls the elevator to the user's floor.

[0034] In this embodiment, a voice broadcast module is also provided. Upon detecting a user's call, the voice broadcast module emits a built-in interactive voice message, and the corresponding built-in voice message will also be broadcast when the elevator arrives at a station. Through intelligent voice interaction and personalized service, contactless outbound calling can provide a more convenient and efficient customer experience, enhancing customer satisfaction and loyalty. The built-in voice messages of the voice broadcast module can be customized according to the application scenario. Different character voices can be set for different figurines to attract customers and enhance the customer's user experience.

[0035] The outbound call sensing module includes a main control chip, which connects to a touch sensor 3.1 and a contactless sensing module. The touch sensor 3.1 detects touch actions through capacitive sensing. The main control chip samples the capacitance change signal in real time and transmits the communication signal to the signal conversion board 2 when a touch action is detected. The sensing electrodes on the internal circuit board of the touch sensor 3.1 form a capacitive circuit with the human body; the electrical characteristics of the human body change the capacitance value of the sensing electrodes. The main control chip samples the capacitance change signal in real time through its internal analog-to-digital converter (ADC) module, analyzes the capacitance change to determine the touch action (such as touching or swiping), triggers the internal logic circuit, and ultimately drives the switching execution circuit (such as a MOSFET) to achieve on / off control.

[0036] The contactless sensing module includes a distance sensor 3.2 and a touchless sensor 3.3. When powered on, it generates an alternating magnetic field. When a metal object and a human body approach each other, the resulting eddy currents generate a reverse magnetic field. The reverse magnetic field changes the inductance value of the induction coil inside the distance sensor 3.2.

[0037] The change in inductance of the induction coil inside the distance sensor 3.2 will affect the frequency and amplitude of the oscillation circuit inside the non-touch sensor 3.3; the detection circuit of the main control chip amplifies the signal change of the oscillation circuit through the amplification circuit, and transmits the communication signal to the signal conversion board 2 when an effective change in inductance is detected.

[0038] The distance sensor 3.2 and the non-touch sensor 3.3 generate an alternating magnetic field when powered on.

[0040] After receiving the paging signal from the outbound call sensor module, the signal conversion board 2 controls the buzzer to turn on and triggers the buzzer to sound.

[0041] After the signal conversion board 2 receives the paging signal from the outbound call sensor module, the control signal feedback light 5 lights up. After the elevator arrives at the station, the control signal feedback light 5 turns off.

[0042] Example 3: This example provides a split-type elevator call device, including a signal conversion board 2 connected to the elevator control circuit 1. The signal conversion board 2 is connected to the call sensor module, the feedback buzzer 4, and the signal feedback light 5, respectively. The call sensor module, the feedback buzzer 4, and the signal feedback light 5 are placed in different parts of a large collectible figure. Large collectible figures are generally half-body height, i.e., three-dimensional collectible models of about 1m-1.5m in size. Using large collectible figures as the carrier of the elevator call device can increase aesthetics and enhance the user experience.

After detecting the user's elevator call action, the signal conversion board 2 sends a specific floor command to the elevator control circuit 1, which then calls the elevator to the user's floor.

[0044] In this embodiment, a voice broadcast module is also provided.

[0049] By employing both contact and contactless sensing methods, it adapts to a wider range of application scenarios. During pandemics or in special settings such as hospitals, contactless elevator call systems avoid direct contact between passengers and the elevator's call device, reducing the risk of cross-infection and protecting passenger health and safety. Furthermore, contactless sensors are less susceptible to contamination and damage, have a long lifespan, and reduce maintenance costs and repair frequency.

[0053] The elevator control circuit 1 contains an elevator call module 6. Upon receiving a specific floor command generated by the signal conversion board 2, the elevator call module 6 calls the elevator to the designated floor. For the safety of the elevator control system, the communication signal within the elevator control circuit 1 is an encrypted shaft signal. Therefore, the elevator call module 6 and the signal conversion board are used for encryption and decryption to ensure the safety of the elevator system. Meanwhile, the signal conversion board 2 is not directly connected to the elevator system; it functions as a separate external system, facilitating retrofitting and independent maintenance of existing elevators.
