The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] In the description of this utility model, it should be understood that the terms "length," "upper," "lower," "front," "rear," "left," "right," "top," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The terms used in this application include: The COP (Car Operating Panel) is the control panel inside the elevator car, which includes floor buttons, door open / close buttons, alarm buttons, etc., for passengers to operate the elevator.

[0021] CLL is a safety signal in elevator door systems, indicating that the car doors are fully closed and mechanically locked. It is typically generated by electrical contacts (or sensors) of the door lock device to ensure that the doors are in a safe locked state before operation.

[0022] In traditional elevator control systems, door lock control is usually driven by signals directly output from the main board, including: manual door lock control (such as electric bolt locks and mechanical locks); electric door opener control (such as automatic swing doors and center-opening doors); and door lock status detection (whether the door is closed properly).

[0023] Traditional solutions typically employ independent wiring, meaning that each floor's electric bolt lock requires a separate control cable and floor switch signal line; electric door operators (such as automatic doors) require additional shaft cables and door operator controllers; and manually operated doors can usually only control a single door (such as the car door), requiring additional circuitry for multi-door control. This architecture leads to complex wiring, high costs, and difficult maintenance, especially in high-rise or multi-door elevators.

[0024] Existing elevator door control systems have the following defects: 1. Manual door control only supports single door; additional wiring is required for expansion to multiple doors. 2. Electric bolt locks and electric doors require independent control cables and floor switches, resulting in complex wiring in the shaft; 3. The motherboard directly outputs the door lock signal, resulting in poor anti-interference capability and insufficient expandability; Therefore, it is necessary to conduct research to address the aforementioned deficiencies in the existing technology and provide a lock control system solution that optimizes the shortcomings of the existing technology.

It communicates with the outside world through a communication module, and the main control boards on different floors also communicate with each other through the communication module. The input module collects input signals, including forward / reverse limit signals, safety circuit signals, etc. The input signals are transmitted to the microprocessor module through the input module, which performs logical judgment based on the signals to determine the action to be executed, and drives the motor / door through the output module.

[0037] Furthermore, in one embodiment of this utility model, the system further includes a display module; the display module is connected to the microprocessor module, and the display module is used to display the unlocking status and the unlocking plate address.

[0038] This application also includes a power supply module for supplying power to the various modules.

[0039] The elevator unlocking integrated system provided in this application will be described in detail below with specific embodiments: To address the problems in the aforementioned technologies, this invention provides an integrated elevator unlocking control system.

[0040] This integrated unlocking control system is based on the existing external call communication structure and is used to control the elevator's unlocking mechanism and the opening and closing of the electric door operator. It replaces the traditional manual door lock output, electric swing door output, and electric swing door output. It eliminates the need for unnecessary electric bolt lock control cables and corresponding floor switches, as well as electric swing door shaft cables and corresponding floor switches.

[0041] It mainly includes the following modules: main control module, electric gate operator drive module, power supply module, detection module, display module, button module, input module, output module, and communication module. Figure 1 ).

[0042] The communication module is compatible with existing outbound call communication systems and communicates with the main control system. Unlocking panels can also exchange information via the communication module. By reusing the outbound call communication bus, dedicated control lines are reduced, saving on wiring and installation costs. Using the communication bus, the control of manual doors can be expanded from single-door to three-door control.

[0043] The display module is used to display the control board address, unlocking status, stepper motor running speed, and output status of the electric door opener; the control board address can also be set via the button module.

[0044] The detection module is used to detect whether the stepper motor is malfunctioning in real time during operation.

[0045] The optocoupler input module receives external signals, identifies the forward or reverse limit signal, and controls the stepper motor to unlock or lock via the motor drive module.

[0046] The relay module outputs electric swing door opening and closing signals, and the external electric door opener receives the corresponding signals to execute the door opening and closing actions.

[0047] This utility model is designed to optimize traditional door lock control systems and provides an integrated elevator unlocking control system.

[0048] It mainly includes the following modules: main control module / microprocessor module ( Figure 2 ), Electric door operator drive module ( Figure 3 ), power module ( Figure 4 ), detection module ( Figure 5 ), display module ( Figure 6 ), button module ( Figure 7 ), input module ( Figure 8 ), output module ( Figure 9 ), communication module ( Figure 10 ).

[0049] The communication module uses the RS485 communication protocol to build a communication circuit for communication with the external main control system. The unlocking boards also exchange information via the RS485 communication protocol. Utilizing the communication bus, only two communication lines and a power line are needed for connection, optimizing the problems of complex traditional wiring, large wire consumption in high-rise elevators, and congested shafts.

[0050] The current detection module is equipped with a current sampling circuit to detect the current status of the motor drive chip in the unlocking control system in real time. It can interact with the elevator main control system in a timely manner, report motor abnormalities, and help to quickly locate the fault.

[0051] The display module uses an 8-bit shift register 74HC595 with tri-state output, saving main control resources, to control the display content of the digital tube, which is used to display the control board address, unlocking status and output status of the electric door opener.

[0052] The button module allows setting the control board addresses for different floors. An address ID is set, and after setting, the information is input into the main control system. The control board address is set via button trigger time. Pressing and holding the setting button for 5 seconds displays the current address on the digital display. Each press increments the address by 1. After 5 seconds of inactivity, the address display remains lit, indicating the address is saved. The button module can also be used to adjust the motor speed. A short press of the button for 1 second sets the current motor speed. Each press increments the speed by 1, up to the set maximum speed, and then returns to the minimum speed.

[0053] Each floor is equipped with an unlocking control board with a unique address ID. All floor unlocking control boards interact with the main control system in the elevator control cabinet via RS485 communication, identifying the corresponding floor information through the address ID.

[0054] Unlocking Instructions: For manual doors, the door must be pushed to the fully closed position to trigger the mechanical lock hook or latch, activating the electrical circuit. Upon receiving the electrical signal, the main control system will output an elevator door unlocking signal. For automatic doors, sensors determine that the door is fully closed and transmit a signal to the main control system. Upon receiving the electrical signal, the main control system will output an elevator door unlocking signal.

[0055] When the elevator door unlock signal is output, the communication module of the unlocking control system on each physical floor receives the signal via the RS485 communication protocol. The MCU controls the motor drive module, instructing the stepper motor to rotate forward to unlock and release the door lock restriction. When the motor rotates to the set limit position, it triggers a mechanical switch or sensor, outputting a forward limit signal. When the forward limit signal is input to the unlocking control board, it is received by the optocoupler input module. After obtaining the signal, the MCU controls the motor drive module, instructing the stepper motor to stop rotating. Here, the stepper motor rotates to the set limit position, then triggers the signal to stop the motor; at this point, it is in the unlocked state, allowing subsequent electric door opener operation.

[0056] When the stepper motor is in forward rotation unlocking mode and the optocoupler input module receives the forward rotation limit input signal, the unlocking control board outputs an electric swing door signal through the control relay output module 1, triggering the external electric door opener to push open the car door. When the elevator is leveled and in a safe state, the unlocking control board receives the unlocking command, outputs a signal to drive the stepper motor, and releases the door lock (allowing door opening); then the unlocking control board outputs a signal to the external door operator system, triggering the external electric door opener to open the car door.

[0057] Lockout Instructions: When the elevator comes to a stop at a level floor, the elevator main control system will output an elevator door lockout signal after verifying the leveling and confirming that the door opening conditions are met.

[0058] When the elevator door lock signal is output and CLL is established, the communication module of the unlocking control system on the physical floor where the car is located receives the RS485 communication signal from the main control cabinet. Then, the MCU controls the motor drive module to instruct the stepper motor to reverse and lock, entering the door lock restriction state. When the motor reverses to the set limit position, it will trigger a mechanical switch or sensor to output a reverse limit signal. When the reverse limit signal is input to the unlocking control board, it receives the signal through the optocoupler input module. After the MCU obtains the signal, the unlocking control board drives the motor to stop rotating.

[0059] The system is configured with two lock settings: an external call lock time (the time from when a passenger presses the external call button to when the door lock is fully unlocked) and an internal call lock time (the time from when a passenger presses the target floor button inside the car to when the door lock is fully unlocked). Once the external or internal call lock times are met, or when the COP (Continuous Opening Control) issues a closing command, the unlocking control board controls relay module 1 to stop outputting the electric swing door signal for 0.5 seconds. Then, it controls relay module 2 to output the electric swing door closing signal, instructing the electric door opener to close the car door. After closing and confirming that the CLL (Continuous Opening Control) is active, the unlocking control board sends a signal to instruct the stepper motor to reverse and lock. When the stepper motor reverses to its limit position, it triggers a mechanical switch or sensor, outputting a reverse limit signal. Upon receiving the reverse limit signal, the unlocking control board instructs the stepper motor to stop rotating, and the unlocking control board controls relay module 2 to stop outputting the electric swing door closing signal. The overall system is as follows: Figure 11 As shown.

[0060] On the other hand, this application provides an elevator that includes the aforementioned elevator unlocking integrated system.

[0061] As described above, the system provided in this application simplifies wiring and reduces costs. Traditional solutions require independent cables for each floor's electric bolt lock and electric door operator, resulting in complex parallel wiring. The unlocking control system reuses the external call communication bus, reducing dedicated control lines and saving on wiring and installation costs. The unlocking control system adopts digital communication and a modular design, reducing the risk of poor contact, enabling remote diagnostics and modular replacement, and facilitating maintenance. The unlocking control system can be expanded to control up to three doors, suitable for scenarios such as freight elevators and medical elevators. It can integrate fault detection (such as abnormal current) and report to the system, improving security.
