Description

Technical Field

[0001] This utility model relates to the field of elevator accessories technology, and in particular to a floor announcer control system. Background Technology

[0002] As society pays more attention to accessible facilities, elevator floor announcers have become a basic component of some elevators, but some older elevators still do not have this function.

[0003] To accurately determine the current floor, existing elevator announcement systems typically require one announcement per elevator. The announcement is installed inside the elevator and is equipped with a floor reading module. It can remotely connect to the elevator's lifting and lowering control structure via a wireless connection module to determine the current floor based on the elevator's lifting and lowering value.

[0004] When blind people travel, if they encounter old elevators without floor announcers, or if they arrive at an unfamiliar building, they will have difficulty operating the elevator because they are unsure of the location and configuration of the announcer. This causes inconvenience for blind people when taking elevators. Utility Model Content

[0005] The main purpose of this utility model is to provide a floor announcement controller, which is easy to carry, provides accurate announcements, and ensures precise and reliable elevator floor positioning.

[0006] To achieve the above objectives, this utility model proposes a floor announcement controller, including a housing, wherein the housing is connected to:

[0007] A button module is provided for blind people to operate the elevator to set the floor they want to go to;

[0008] Floor positioning sensor assembly, used to determine the current floor based on changes in the environment;

[0009] The main control unit is electrically connected to the button module and the floor positioning sensor assembly. The main control unit is equipped with a clock circuit to ensure the accurate timing of the system.

[0010] The broadcast module is electrically connected to the button module, the floor positioning sensor component, and the main control unit. When the floor positioning sensor component detects that the current floor is the elevator floor set by the button module, the broadcast module broadcasts the current floor information.

[0011] In one embodiment of this application, the main control unit is configured with a power management module to ensure the safety and stability of battery charging;

[0012] The power management module is equipped with a Type-C interface, which enables the internal charging chip to be connected to an external power source.

[0013] In one embodiment of this application, the power management module is configured with a first power conversion unit and a second power conversion unit. The first power conversion unit is electrically connected to the floor positioning sensor assembly and the broadcast module, and is used to convert the 5V input voltage into a 3.6V output voltage.

[0014] The second power conversion unit is electrically connected to the main control unit and is used to convert the 5V input voltage into a 3.3V output voltage.

[0015] In one embodiment of this application, the main control unit is further connected to a human-computer interaction module. The human-computer interaction module is equipped with an LCD display screen and a voice input module. The voice module is connected to a microphone and is used to receive voice information input by the user and send it to the main control unit for processing.

[0016] The LCD display shows the corresponding floor information based on the floor positioning sensor component, and the main control unit provides feedback on the elevator's floor location.

[0017] In one embodiment of this application, the human-computer interaction module is further configured with a broadcasting unit, which is configured with voice broadcasting function and / or vibration broadcasting function.

[0018] In one embodiment of this application, the broadcasting module is configured with a storage and communication module, which communicates with the main control unit via an SPI interface to read and write voice files, floor data, and system configuration.

[0019] In one embodiment of this application, the floor positioning sensor assembly includes:

[0020] Temperature sensor is used to determine the air pressure difference value corresponding to real-time floor switching based on ambient temperature;

[0021] A horizontal height sensor is used to determine the current floor by comparing the real-time collected air pressure value with the corresponding air pressure difference value when switching floors.

[0022] By adopting the above technical solution, this utility model has the following advantages:

[0023] 1. The control circuit is equipped with a button module, allowing blind users to select their desired floor at any time. Pressing the button sends a first control signal to the main control unit, which records this signal. This allows the floor locator to identify the desired floor and provide timely reminders. Upon receiving the first control signal, the main control unit sends a corresponding adjustment command to the broadcast module, which includes a microphone and a voice IC. The broadcast module repeatedly announces the desired floor to prevent accidental selection. This structure enhances elevator control intelligence, effectively assists blind users, and demonstrates high reliability.

[0024] 2. The control circuit also includes a floor positioning sensor assembly. This assembly uses a sensor module that only requires power to operate. The sensor module and the announcer can be directly connected or configured with a wireless connection module for external input, allowing the control circuit to receive transmitted external physical information to determine the current floor. The most noticeable change in data during elevator ascent and descent is generally air pressure. The air pressure change within the elevator is significant and objective. The sensor module uses both a pressure sensor and a temperature sensor. The pressure sensor collects air pressure data and determines the current floor based on the pressure difference. Because air pressure often changes uniformly due to temperature variations, the control circuit can determine the pressure difference that indicates a floor has risen or fallen based on the data from the temperature sensor. Furthermore, the connection to the pressure sensor enables the control circuit to determine the current floor. Since these sensors collect objective physical data and only require power to operate, they can function normally in enclosed environments where satellite signals are unavailable, such as elevators. This avoids reliance on traditional wireless signal positioning, improving positioning accuracy and reliability.

[0025] 3. The floor positioning sensor component will output a second control signal to the main control unit. After receiving the second control signal, the main control unit will first compare it with the signal input by the button module, and then send corresponding control commands to the broadcast module. The control commands include ordinary floor broadcast signals, ready broadcast signals, and arrival broadcast signals. The broadcast module can broadcast floor prompts and reminder voices according to different signals to ensure that blind users can use the elevator at their own pace, which is conducive to assisting blind users in their normal work and life.

[0026] 4. The main control unit has a built-in clock circuit. The clock circuit uses a 32.768kHz crystal to provide accurate timing signals to the main control unit, ensuring system clock synchronization. This is beneficial for realizing the intelligence of the elevator positioner control system and improving the reliability of the entire system. Attached Figure Description

[0039] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] Reference Figures 1 to 9 To achieve the above objectives, this utility model proposes a floor announcer control system, including a housing, a button module 1 for blind people to operate to set the elevator floor to be reached, and a floor positioning sensor component 2 for determining the floor according to environmental changes.

[0042] It is also connected to the main control unit 3 and the broadcast module 4. The main control unit 3 is electrically connected to the button module 1 and the floor positioning sensor component 2. The main control unit 3 is equipped with a clock circuit 31 to ensure the accurate timing of the system.

[0043] The broadcast module 4 is electrically connected to the button module 1, the floor positioning sensor component 2, and the main control unit 3. When the floor positioning sensor component 2 detects that the current floor is the elevator floor set by the button module 1, the broadcast module 4 broadcasts the current floor information.

[0044] This application relates to the internal circuitry and control system of a floor announcement controller. Both the circuitry and control system are protected by a housing. The circuitry and control system includes various functional circuits and units, as well as control hardware. This control hardware is connected to the functional circuits and units via electrical signals. The housing protects the entire control circuitry and can also be equipped with a connection structure, allowing users to attach a lanyard to the housing. The housing carries the entire announcer, making it easy for users to carry and preventing loss. This makes it more convenient for blind users to use and can effectively facilitate their travel.

[0045] The control circuit includes a button module 1, allowing blind users to select their desired floor at any time. Pressing the button sends a first control signal to the main control unit 3, which records this signal. This allows the floor locator to identify the desired floor. The button circuit enables the floor locator to know the user's floor and provide timely reminders. Upon receiving the first control signal, the main control unit 3 sends a corresponding adjustment command to the broadcast module 4. The broadcast module 4, consisting of a microphone and a voice IC, repeatedly announces the desired floor to prevent accidental selection. This structure enhances elevator control intelligence, effectively assists blind users, and demonstrates high reliability.

[0046] The control circuit also includes a floor positioning sensor assembly 2. This assembly uses a sensor module that only requires power to operate. The sensor module and the announcer can be directly connected or configured with a wireless connection module for external input, allowing the control circuit to receive transmitted external physical information to determine the current floor. The most noticeable change in data during elevator ascent and descent is generally air pressure. When the elevator rises or falls, the change in air pressure inside the elevator is obvious and objective. The sensor module uses an air pressure sensor and a temperature sensor. The air pressure sensor collects air pressure and determines the current floor based on the air pressure difference. Because of temperature differences, air pressure often changes uniformly. Therefore, the control circuit can determine how much air pressure difference represents a floor rise or fall based on the data transmitted from the temperature sensor. Furthermore, because the control circuit is also connected to an air pressure sensor, it can determine the current floor. Since these sensors collect objective physical data and only require power to operate, they can operate normally in enclosed environments where satellite signals cannot be accessed, such as in an elevator.

[0047] In this application, the barometric pressure sensor is a BMP280 barometric pressure sensor. Other sensors that can achieve similar functions are also within the scope of this application. The BMP280 communicates with the MCU through the I2C interface and determines the floor of the elevator by measuring the pressure difference. It is suitable for closed environments where satellite signals cannot be accessed, avoiding reliance on traditional wireless signal positioning and improving the accuracy and reliability of positioning.

[0048] The floor positioning sensor component 2 will output a second control signal to the main control unit 3. After receiving the second control signal, the main control unit 3 will first compare it with the signal content input by the button module 1, and then send corresponding control commands to the broadcast module 4. The control commands include ordinary floor broadcast signals, ready broadcast signals, and arrival broadcast signals. The broadcast module 4 can broadcast floor prompts and reminder voices according to different signals to ensure that blind users can use the elevator at their own pace according to their needs, which is conducive to assisting blind users in their normal work and life.

[0049] The main control unit 3 has a built-in clock circuit 31. The clock circuit 31 uses a 32.768kHz crystal to provide accurate timing signals to the main control unit 3, ensuring the clock synchronization of the system. This is beneficial for realizing the intelligence of the elevator positioner control system and improving the reliability of the entire system.

[0050] The control system is also equipped with an anti-static protection structure, including multiple TVS diodes. By using TVS diodes at key system interfaces, such as external interfaces, displays, and keypad lights, comprehensive electrostatic protection is provided to prevent electrostatic damage to the circuits and ensure stable system operation.

[0051] The circuit design reserves multiple unconnected pins (NC), providing a hardware expansion interface for future functional upgrades (such as wireless modules). Continuous upgrades will improve the user experience.

[0052] See also Figures 5 to 7 The main control unit 3 is equipped with a power management module 5 to ensure the safety and stability of battery charging;

[0053] The power management module 5 is equipped with a Type-C interface, which enables the internal charging chip to be connected to an external power source.

[0054] The control system of this application comes with a built-in power management module 5, which can charge the entire circuit. The Type-C interface is connected to an external power source, and the charging chip (U3) controls the charging of the lithium battery to ensure the safety and stability of the battery during the charging process.

[0055] See also Figures 6 to 7 The power management module 5 is equipped with a first power conversion unit 51 and a second power conversion unit 52. The first power conversion unit 51 is electrically connected to the floor positioning sensor assembly 2 and the broadcast module 4, and is used to convert the 5V input voltage into a 3.6V output voltage.

[0056] The second power conversion unit is electrically connected to the main control unit 3 and is used to convert the 5V input voltage to the 3.3V output voltage.

[0057] In this application, the working chip of the first power conversion unit 51 is the voltage conversion chip LN1152, which can stably convert the 5V input voltage to 3.6V, mainly used to supply the sensors and display screen so that they can work stably; the working chip of the second power conversion unit 52 is DS8561, which converts the voltage to 3.3V to supply the MCU (main control unit 3) and other circuits. Through the power conversion module, the safe and stable operation of the entire control system can be guaranteed, which can effectively improve the user experience.

[0058] See also Figures 8 to 9 The main control unit 3 is also connected to a human-computer interaction module 6. The human-computer interaction module 6 is equipped with an LCD display screen 61 and a voice input module 62. The voice module is connected to a microphone and is used to receive the voice information input by the user and send it to the main control unit 3 for processing.

[0059] The LCD display screen 61 displays the corresponding floor information based on the floor positioning sensor component 2, and provides feedback on the elevator's current floor based on the main control unit 3.

[0060] Selecting the desired floor via button module 1 is cumbersome and cannot be done quickly. To make the elevator control system more intelligent and more reliable, a human-machine interaction module 6 is set up to achieve the above purpose. The human-machine interaction module 6 includes an LCD display 61 and a voice input module 62. The voice module receives the voice information input by the user through a microphone (MIC1), the operational amplifier chip amplifies the signal and sends it to the MCU for processing; and the floor prompt voice is played through a pre-recorded voice IC.

[0061] The LCD display 61 is used to display floor information, providing real-time feedback on the elevator's current floor. This allows non-blind users to also have a good interactive experience.

[0062] See also Figures 8 to 9 The human-computer interaction module 6 is also equipped with a broadcasting unit, which has voice broadcasting function and / or vibration broadcasting function.

[0063] The floor announcement controller is mainly used to determine the current floor using a special sensor in the absence of external signals. It compares the floor with the floor the user initially inputs. When the user approaches the desired floor, the announcement unit reminds the user to get off the elevator in time, making it easier for blind users to use the elevator. Since the main users of the floor announcement controller are blind people, the most effective reminder method is voice announcement or vibration announcement, so that the user can determine whether they need to get off the elevator, making it more convenient for blind users to travel.

[0064] See also Figure 4In one embodiment of this application, the broadcast module 4 is configured with a storage and communication module 41. The storage and communication module 41 communicates with the main control unit 3 through the SPI interface and is used to read and write voice files, floor data and system configuration.

[0065] The TRA1313BE memory chip stores voice files, floor data, and system configuration. This memory chip communicates with the MCU via an SPI interface to read and write data.

[0066] See also Figures 1 to 3 The floor positioning sensor assembly 2 includes a temperature sensor for determining the air pressure difference corresponding to the real-time floor switching based on the ambient temperature, and a sensor for determining the current floor level by comparing the real-time collected air pressure value with the air pressure difference corresponding to the floor switching.

[0067] Because the signal quality in elevator lobbies is generally poor, the broadcast controller is prone to malfunctions such as travel delays. Blind users often find it difficult to determine the cause of the malfunction, making it inconvenient to use. Therefore, in this application, the floor positioning sensor component 2 determines the current floor through external physical information. The most significant data change during elevator ascent and descent is generally air pressure. When the elevator rises or falls, the air pressure change inside the elevator is obvious and objective. The horizontal height sensor collects air pressure and determines the current floor based on the air pressure difference. Because of different temperatures, air pressure often changes uniformly. Therefore, the floor positioning sensor component 2 can determine how much air pressure difference represents a floor rise or fall based on the data transmitted from the set temperature sensor. Furthermore, because the control circuit is also connected to an air pressure sensor, the control circuit can determine the current floor. Since these sensors collect objective physical data and only need to be powered on to work, they can work normally in enclosed environments where satellite signals cannot be accessed, such as in elevators.
