[0017] In the description of the present invention, it should be noted that, for directional words, such as the terms "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific protection scope of the present invention.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Therefore, the terms "first" and "second" may explicitly or implicitly refer to one or more of these features. In the description of this utility model, "several" and "a number" mean two or more, unless otherwise specifically defined.

[0019] See the accompanying drawings. The floor wireless call device described in this embodiment includes a host module and multiple extension modules. The host module is installed in the elevator, and the extension modules are installed on each floor. The host module is also connected to a four-position DIP switch (SW_I3, SW_I4, SW_I5, SW_I6) for setting the communication signal, host, and extensions.

[0020] The host module includes a main control MCU, a display screen and a wireless communication module. The main control MCU is a single-chip microcomputer U4, model STM32L051C8. The main control MCU includes a floor door status receiving unit, a floor call information receiving unit, a display control unit and an elevator control unit. The display control unit is used to control the display screen, and the display screen can display the floor number where the faulty floor door is located; the elevator control unit controls the operation of the elevator.

[0021] The extension module includes a floor caller, a landing door trigger, and a landing door detection circuit. The landing door detection circuit is used to receive the door opening signal from the landing door trigger, detect the opening and closing status of the landing door, and transmit the door opening signal to the main control MCU via the wireless communication module. The main control MCU transmits the door opening signal and the corresponding floor number to the display screen for display. The floor caller transmits floor call information to the main control MCU.

[0022] The extension module also includes a power collection circuit for collecting power information of the extension module and sending the power information to the single-chip microcomputer U4, which then sends the power information to the display screen.

[0023] In actual use, the extension needs to be bound first:

[0024] After the host module's single-chip microcomputer U4 is powered on, the wireless communication module is driven through the SPI1 interface (SPI1_CSN, SPI1_SCK, SPI1_MISO, SPI1_MOSI) to receive binding command data. When the floor call button of the extension module is pressed, the signal passes through the IO detection circuit (SW_IO), turns on the IO_VCC interface power supply, and powers on the single-chip microcomputer through the VCC_MCU port. At the same time, the pressing signal data is processed, and the battery power is collected through the ADC interface (BAT_MON). Then, the wireless communication module is driven through the SPI1 interface (SPI1_CSN, SPI1_SCK, SPI1_MISO, SPI1_MOSI) to send the floor binding data and power data. The corresponding sending indicator red light (LED_RED) lights up for one second and then goes out. After the host module receives the command through the wireless communication module, the corresponding receiving indicator green light (LED_GRN) lights up for one second and then goes out, and the binding data and power data are sent to the display screen through the UART2 serial port (RXD2, TXD2) for binding processing.

[0025] When a floor call is made: the floor call button of the extension module is pressed, and the signal passes through the IO detection circuit (BOTTON_IO), turning on the power supply, and powering on the microcontroller U4 through the VCC_MCU port. At the same time, the pressing signal data is processed, and then the wireless communication module is driven to send the floor call data through the SPI1 interface (SPI1_CSN, SPI1_SCK, SPI1_MISO, SPI1_MOSI). The corresponding sending indicator red light (LED_RED) lights up for one second and then goes out; after the host module receives the instruction through the wireless communication module, the corresponding receiving indicator green light (LED_GRN) lights up for one second and then goes out, and sends the call data to the display screen through the UART2 serial port (RXD2, TXD2) for call data processing.

[0026] During floor door monitoring: after the extension module detects that the floor door is opened through the port (GATE_IO) of the floor door detection circuit, it drives the microcontroller U4 to power on through the MOS tube, and drives the wireless communication module to send the floor door open / close data through the SPI1 interface (SPI1_CSN, SPI1_SCK, SPI1_MISO, SPI1_MOSI). The corresponding sending indicator red light (LED_RED) lights up for one second and then goes out; after the host module receives the instruction through the wireless communication module, the corresponding receiving indicator green light (LED_GRN) lights up for one second and then goes out, and sends the call data to the display screen through the UART2 serial port (RXD2, TXD2) for call data processing.

[0027] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
