Technical Field

[0001] The embodiments of the present invention relate to the field of intelligent building control technology, and in particular to a global IoT control system and method based on the central control screen of an elevator car. Background Technology

[0002] In modern society, elevators, as an important means of vertical transportation, are widely used in various buildings and public places. Currently, smart homes are becoming an integral part of our daily lives; from smart refrigerators to automatic curtains, various smart devices are gradually changing our lifestyles.

[0003] Among these smart home devices, elevators, as a vital means of transportation connecting different floors, are gradually being integrated into this transformation. Better integration of elevators into smart homes not only improves living comfort and convenience but also effectively enhances safety and energy efficiency. Therefore, developing an intelligent elevator control system for smart home linkage, which can provide both safety and emergency guidance while enabling the interconnection of various home appliances, has significant practical implications and market demand. Summary of the Invention

[0004] This invention provides a global IoT control system and method based on the central control screen of an elevator car. Through multi-protocol fusion and spatial perception algorithms, it realizes centralized control of elevator operation status, floor public equipment and user's whole-house smart terminals.

[0005] In a first aspect, embodiments of the present invention provide a global IoT control system based on an elevator car central control screen, comprising:

[0006] The elevator car's central control screen, elevator control system, cloud platform, and user terminal;

[0007] The car center control screen integrates a multi-protocol gateway, and the car center control screen is connected to the elevator control system through the multi-protocol gateway to control and obtain the elevator's operating status;

[0008] The car's central control screen is connected to the floor public equipment and the user's whole-house smart terminal via a multi-protocol gateway, and is used to control the floor public equipment and the user's whole-house smart terminal;

[0009] The car's central control screen is connected to the cloud platform via a multi-protocol gateway. The cloud platform is connected to the user terminal. The cloud platform is used to send user commands received by the user terminal to the car's central control screen so that the user commands can be executed through the car's central control system.

[0010] Optionally, the system also includes a voice recognition module for receiving user voice commands and, when the elevator malfunctions, enabling real-time voice communication between trapped personnel and the outside world, as well as broadcasting self-rescue guidance information.

[0011] Optionally, the system also includes an Internet of Things (IoT) module for enabling data exchange between elevators, floor public facilities, and users' smart terminals throughout the house.

[0012] Optionally, the car control screen also integrates a space perception module, which is used to automatically associate the physical space where the car is located through elevator signals and positioning signals, and determine the target control domain based on the physical space.

[0013] Optionally, by using elevator signals and positioning signals, the physical space of the car can be automatically associated, and the target control domain can be determined based on the physical space, including:

[0014] If the elevator is in operation or not at a floor level, the physical space where the elevator car is located is the elevator shaft.

[0015] Otherwise, the target control domain is determined as the private domain of the target floor or the public area of ​​the floor based on the strength of the elevator leveling signal, elevator door operator signal, and positioning signal.

[0016] Optionally, the car's central control screen provides a smart device operation interface for the user based on the floor where the target control domain is located.

[0017] Optionally, the car control screen can simultaneously support direct connection between cloud HTTP commands and local CAN bus, and switch to low power mode when the elevator is detected to be in sleep mode.

[0018] Secondly, the present invention also provides a global IoT control method based on the central control screen of an elevator car, implemented by any of the methods described in the above embodiments, including:

[0019] Receive scene commands initiated by users through user terminals or through the car's central control screen;

[0020] The user's target control domain is detected through the spatial perception module;

[0025] Figure 2 This is a control principle diagram of a global IoT control system based on the central control screen of an elevator car, provided as an embodiment of the present invention. Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures. Example

[0027] Figure 1 This invention provides a framework diagram of a global IoT control system based on an elevator car central control screen. The system includes: a car central control screen, an elevator control system, a cloud platform, and a user terminal.

[0028] Furthermore, the car's central control screen integrates a multi-protocol gateway for connecting to the elevator, cloud platform, and various smart devices. (See also...) Figure 2 The multi-protocol gateway interconnects with devices in the public device layer via CAN bus / PoE power supply and with devices in the home device layer via WiFi / Zigbee / Matter. For example, it can control a range of smart home products such as door access control, curtains, televisions, home appliances, and smoke detectors using Bluetooth or ZigBee chip networking, enabling various interactive control methods and compatibility with multiple devices. It allows for individual control, group control, and customized scene control; furthermore, power amplifier chips can be used to enhance communication distance and ensure communication quality.

[0029] For example, the car's central control screen is connected to the elevator control system via a CAN bus to control and acquire the elevator's operating status, such as collecting various information including faults and elevator signals (e.g., light curtain, weighing, door locks, door opening and closing). The car's central control screen is connected to smart lighting fixtures via a ZigBee gateway and to the central air conditioning system via a KNX bus.

[0030] Furthermore, the car's central control screen is connected to the cloud platform via Wi-Fi, and the cloud platform is connected to the user terminal. The cloud platform is used to send user commands received by the user terminal to the car's central control screen so that the user commands can be executed through the car's central control system.

[0031] Based on the above embodiments, the system also includes a voice recognition module for receiving user voice commands, allowing users to directly issue commands to the elevator without manually operating the buttons.

[0032] Furthermore, in the event of an elevator malfunction, real-time voice communication and self-rescue guidance information broadcasts are provided between trapped individuals and the outside world to offer necessary information and guidance, helping trapped individuals understand the malfunction and take appropriate self-rescue actions. For example, when the elevator malfunctions, the system will automatically broadcast malfunction information and prompt trapped individuals to try pressing the door open button to rescue themselves. This self-rescue prompt function can increase the chances of trapped individuals escaping and improve self-rescue efficiency. This embodiment also enables the elevator, based on Internet of Things (IoT) technology, to exchange data with other smart home devices.

[0033] Furthermore, the car's central control screen also integrates a spatial perception module, which is used to automatically associate the physical space where the car is located through elevator signals and positioning signals, and determine the target control domain based on the physical space.

[0034] Specifically, if the elevator is in operation or not at a floor level, the physical space where the car is located is the elevator shaft, and the control target of the car's central control screen is the elevator itself.

[0035] Otherwise, the target control domain is determined as the private domain of the target floor or the public area of ​​the floor based on the strength of the elevator leveling signal, elevator door operator signal, and positioning signal.

[0036] The elevator leveling signal determines the floor the elevator car is on, and the door operator signal determines the elevator's opening and closing. These positioning signals can be BLE (Bluetooth Low Energy) signals. If the detected positioning signal from a resident on the target floor is weak, it means the elevator has not yet entered the home's private domain, and the target control domain of the elevator car's central control screen is the public area of ​​the target floor. If the detected positioning signal from a resident on the target floor is strong, the target control domain of the elevator car's central control screen is switched to the smart devices within the target floor's home's private domain.

[0037] Multiple intelligent control scenarios can be achieved through the car central control screen, and the control scenarios can be customized according to personal habits or preferences. For example, home mode, meeting mode, rest mode, etc. Different modes correspond to different preset control logics, and the linkage effect of commands is achieved according to the preset control logic. The status of this elevator and the preview of the target floor are displayed through the scene setting on the central control screen (such as "The lighting on the 3rd floor has been pre-activated"), and a whole-house home appliance aggregation panel will automatically pop up on the docking floor to control the smart home appliances connected to the platform on the arriving floor.

[0038] In addition, this embodiment also provides a global Internet of Things control method based on the elevator car central control screen, which specifically includes:

[0039] Receiving the scene instructions initiated by the user through the user terminal or through the car central control screen;

[0040] Detecting the user's target control area through the space perception module;

[0041] Sending control instructions to the target devices through the multi-protocol gateway according to the scene instructions and the target control area; the target devices include the elevator itself, floor public devices, and the user's whole-house smart terminal;

[0042] Feeding back the elevator operation status and the preview of the target floor during the execution of the control instructions to the user interface.

[0043] The car central control screen in this application synchronously supports cloud HTTP instructions and direct connection to the local CAN bus. When the elevator is detected to be in the sleep state, the car central control screen switches to the LORA low-power mode.

[0044] This invention takes the "home mode" as the preset scene and introduces the execution steps of issuing scene instructions directly through the car central control screen and through the mobile phone APP respectively:

[0045] Scene: The scenario of taking the elevator home from work

[0046] Step 1: Click the "Home Mode" (which can be customized) on the central control screen in the car → The system schedules the elevator in advance through the reservation call technology.

[0047] Step 2: During the elevator's upward movement → Automatically turn on the aisle lights on the target floor + the living room air conditioner (executed through the PoE-powered relay).

[0048] Step 3: At the moment when the elevator stops at the floor of the home door → The central control screen switches to the home control interface and issues commands: The smart door lock releases the security mode, the curtains automatically unfold to the preset angle, and the floor sweeping robot returns to the charging dock.

[0049] The user sends the command "Turn off all devices on the 3rd floor" through the APP → The cloud verifies the user's permissions and device status → Forwards the command to the central control screen → The central control screen turns off the lights / air conditioner on the 3rd floor through the ZigBee gateway → Lowers the electric curtains through the KNX gateway → Feedback of the execution result is sent to the APP.

[0050] Elevator linkage logic: When the mobile app initiates "Home Mode":

[0051] ① The elevator responds to the call command and goes to the 1st floor;

[0052] ② After the car arrives at the first floor, the central control screen automatically turns on the entrance light and unlocks the front door;

[0053] ③ During the elevator's ascent, the living room air conditioning is turned on on different floors (based on user location prediction).

[0054] This invention connects the car's central control screen to the elevator control system, collecting various information such as faults, operation, and elevator signals (e.g., light curtain, weighing, door lock, door opening and closing). It provides multi-protocol gateways, spatial perception modules, and other access to smart home devices, sets various scenarios, and enables one-click control of smart homes. This solves the limitations of traditional elevator control systems, creates a seamless "space shuttle" control experience, and improves the level of smart home integration in home elevators.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
