Referring to Fig. 1, the present invention provides a kind of contactless elevator control method, comprises the following steps:
S1: Obtain the elevator control interface of the mobile terminal and determine that the camera and Bluetooth module of the mobile terminal are turned on;
S2: Control the camera to scan the two-dimensional code set outside the car of the elevator and extract the current floor value from the two-dimensional code, or search for an authorized elevator to enter the elevator, and connect the mobile terminal to the controlled terminal of the elevator through the Bluetooth module;
S3: Generate operation information according to the current floor value and the floor where the elevator is located and display it on the operation interface of the mobile terminal, and obtain the user's gesture track on the operation interface to generate an operation instruction;
S4: Send the operation instruction to the controlled end to control the elevator.

In this embodiment, a main control box is installed in the elevator to operate any buttons and door-close button in the elevator. A five-pin wire is used to connect the power supply and the elevator fire signal or other devices. The main control box is provided with a key for manual switching. The controlled end can be a small control box for operating one or more wall buttons. The mobile terminal can be a mobile phone or a tablet computer with a camera or image acquisition. The elevator control interface is an application applet or a mobile phone application. Taking the mobile terminal as an example, when the camera and Bluetooth of the mobile phone are turned on, it is convenient to scan the QR code and establish a Bluetooth connection. The communication connection between the mobile phone and the controlled terminal is convenient for remote operation. The preset distance between the communication unit of the controlled terminal and the mobile phone is set at five meters, so that a strong wireless signal can be obtained and the sensitivity of wireless control can be improved. QR codes are suitable for public places, such as shopping malls, and also for fixed places such as residences and commercial buildings. On floors where there is no QR code posted, you can directly open the mobile app interface and perform gesture sliding operations to automatically search for nearby authorized lifts. When the lift arrives and the user enters the lift, the mobile app will automatically identify the floor button of the lift according to the data in the existing database and display it on the mobile app operation interface.

It should be noted that if the user’s mobile phone stores the scanned QR code and establishes a communication connection with the controlled terminal, the controlled terminal can be connected to the controlled terminal via Bluetooth within ten meters. As the user approaches the elevator, the Bluetooth signal strength gradually increases. Only when the distance between the mobile phone and the controlled terminal is detected within five meters is the operation information displayed on the mobile application interface. The operation information is matched, and the operation instruction is generated after the matching is successful, and then the operation area of the optional floor is illuminated. If there is a corresponding current floor, operation information and target floor in the historical data stored in the database, then the previous ride information is directly sorted in chronological order. The user only needs to click the confirmation button or slide operation on the elevator operation interface, which is convenient for quick operation and does not require a network connection, saving time. When there is no corresponding current floor in the database, it is necessary to scan the QR code to enter the elevator control interface, bind the user identity information, terminal identification and the elevator control interface to store the authorization information, so that there is no need to log in again or scan the QR code again, and store the authorization information and the process of riding the elevator in the database as new ride information.

In addition, when there are many people in the elevator, the user can independently select the floor with the help of the mobile application of the mobile phone. The mobile application can display the floor number of the elevator and the floor number that can be reached, and can control the buttons of the floors reached without contact. Users operate on their personal mobile phones without touching public facilities such as elevator buttons, which greatly reduces the risk of contact transmission and cross-infection, which is of great significance to the current normalized epidemic prevention and control, and improves the flexibility and experience of users using elevators.

Optionally, the acquiring the gesture trajectory of the user on the operation interface to generate an operation instruction includes:
Obtaining identification information of the mobile terminal, the identification information including user identity information and a target floor;
judging whether the identification information exists in a preset database;
If yes, an operation instruction is directly generated within a preset time and sent to the controlled terminal.

In this embodiment, the gesture trajectory of the user on the operation interface can be a top-down gesture parallel to the display screen of the mobile phone, or a bottom-up gesture, or a click operation or a sliding track on the display screen. The user identity information includes the user's mobile phone number, age, etc., and the identification information is stored in the preset database.

Optionally, the sending the operation instruction to the controlled end to control the lift includes:
When there is at least one elevator reaching the current floor, select the controlled terminal to obtain the target elevator corresponding to the maximum Bluetooth signal strength connected to the mobile terminal;
The selection button information corresponding to the floor in the target elevator is displayed on the operation interface.

In this embodiment, when there is at least one elevator on the same floor, the controlled terminal and the elevator are set in one-to-one correspondence. The ID numbers of the communication units of each controlled terminal are different, the positions of the mobile phone and the controlled terminals of each elevator are different, and the Bluetooth signal strength is also different. Select the controlled terminal with the highest Bluetooth signal strength, which is convenient for quickly establishing a stable connection and improving the control accuracy of the elevator.

Optionally, when it is judged that there are multiple mobile terminals in the selection button information, the received operation instructions are displayed in chronological order on the corresponding floor buttons of the elevator.

In this embodiment, when multiple mobile phones need to be connected to the controlled terminal, the operation instructions can be generated in sequence. Similarly, the floors to be reached are displayed in the elevator. The operation instructions include door opening, closing, buttons, etc. The user can also select a floor on the elevator operation interface after entering the elevator.

It should be noted that the operation instructions include ascending control and descending control. The two-dimensional code is loaded with one or more of the key certificate, device identifier, device parameter or identification number. The mobile phone scans the two-dimensional code posted on the wall and interprets it into a bunch of strings, and the strings are some encrypted data. The controlled end includes a non-control mode, a control mode and a residential mode. The non-control mode is used for elevators in shopping malls and public spaces without time control, and the control mode is used for commercial buildings and elevators in public spaces with time control. Taking the residential model as an example, when registering, the property management enters the information of residents or tenants in the background and distributes electronic keys. The system will generate system user accounts and QR codes based on different user information. The property management will notify the user of the QR code of the downloaded application, the QR code of the user account and how to use it by letter. After receiving the letter, the user downloads the application according to the instructions. Make sure that the camera and Bluetooth functions of the mobile phone are turned on. within the app. When in use, the user takes out the mobile phone to open the app and confirms that the camera and Bluetooth functions are enabled, selects the call elevator, enters the elevator to display the reachable floors, selects the floor, and then presses the button of the floor to light up, and the elevator follows the operation instructions to go to the selected floor. Among them, the mobile phone continuously searches for the devices in the elevator, and determines and locks the elevator with the strongest signal. If there is at least one person calling the elevator at the same time, the signal from the first user will light up the button light, and the mobile phone will also change the screen to wait for the elevator. Execute ten instructions to use the lift to provide convenient operation in different scenarios.
