Description

Technical Field

[0001] This invention relates to the field of electric lock control technology, and in particular to an electric lock control system and method based on elevators. Background Technology

[0002] The elevator door opening and closing system is the first line of defense for elevator safety. It mainly consists of the car door installed on the elevator car and the landing door installed on the floor. These two doors must work together. Only when the elevator car is precisely stopped in the leveling area of ​​the designated floor can the car door and the landing door be opened in unison to ensure that passengers do not accidentally enter the shaft and fall.

[0003] Based on this safety principle, the most basic operational requirement for elevator doors is that the elevator doors must remain closed during elevator operation and when the elevator is stopped but no opening command has been executed. The door system will only be authorized to open when the passenger manually operates the opening button after the elevator has come to a smooth stop.

[0004] Application No. 202010248121.3 discloses an elevator operation control method, system, electronic safety controller, and elevator main controller. The method includes: acquiring an elevator door lock circuit status signal, which includes whether the elevator door lock circuit is open or closed; if the elevator door lock circuit is open, acquiring a door lock area signal and a door-sealing command; when the door lock area signal is valid, controlling the on / off state of a safety relay according to the door-sealing command, wherein the safety relay is connected in series in the power supply circuit of the elevator braking control device. The above-mentioned embodiment acquires the safety circuit status signal and door lock area signal through an electronic safety device, and the electronic safety device controls the safety relay according to the signal from the elevator main controller indicating entry into the door-sealing state. This facilitates the elevator controller in enabling early door opening or re-leveling without the need for an additional early door opening panel, saving on traveling cables and reducing costs.

[0005] The existing technical solutions mentioned above have the following drawbacks: 1. When there is a slight but misalignment between the car door and the landing door due to mechanical wear, installation errors or system failures, the traditional mechanical interlocking mechanism cannot be fully effective, resulting in frequent elevator door failures; 2. When the elevator starts unexpectedly, the passenger's body or belongings may be trapped between the moving car and the stationary landing door, causing serious injury, and the passenger may fall from the gap between the car and the shaft wall to the bottom of the deep elevator shaft. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the objective of this invention is achieved through the following technical solution: An elevator-based electric lock control system; comprising: The locking module, whose input end is connected to the output end of the execution module, is used to lock or unlock the elevator door; The execution module has its input end connected to the output end of the control module, and is used to control the circuit on and off of the locking module according to the door lock control signal; The control module has a first input terminal connected to the output terminal of the leveling detection module and a second input terminal connected to the output terminal of the safety verification module. It is used to determine the elevator operating status based on the leveling sensing signal, generate the door lock control signal, determine the elevator door status, and control the elevator operating status based on the safety closing signal. The leveling detection module is used to detect and determine the running position of the elevator car, generate the leveling sensing signal, and transmit it to the control module. The safety verification module is used to detect and verify the locking status of the elevator door, generate the safety closing signal, and transmit it to the control module. The locking module is a bistable permanent magnet lock or a monostable permanent magnet lock; the locking module includes a permanent magnet and an electromagnetic coil; the permanent magnet is used to generate permanent magnetic force to lock the elevator door; the electromagnetic coil is used to generate a magnetic field to overcome the permanent magnetic force and unlock the elevator door after being energized; The leveling detection module includes a magnetic sensor and a signal feedback device; the leveling sensing signal includes an elevator arrival signal; if the elevator car moves to the leveling position, the magnetic sensor aligns with the electromagnetic coil of the locking module to generate a magnetic pole sensing signal; the signal feedback device feeds back the elevator arrival signal to the control module based on the magnetic pole sensing signal. The safety verification module includes an independent electrical contact and a safety circuit; the independent electrical contact is connected in series with the safety circuit; if the elevator door is locked to the limit position, the independent electrical contact is triggered to close, generating a safety closing signal, which is then transmitted to the control module. The control module includes: The signal receiving unit is used to receive elevator arrival signals and safety closing signals; The signal processing unit is used to generate an opening command based on the elevator arrival signal, and to determine that the elevator door has been locked based on the safety closing signal, and generate an elevator running command. The instruction distribution unit is used to convert the door opening instruction and the elevator operation instruction into a small current signal and transmit it to the execution module.

[0007] By adopting the above technical solution, based on the state machine control algorithm, the magnetic pole induction signal generated when the magnetic sensor of the leveling detection module aligns with the electromagnetic coil of the locking module is used to generate an elevator arrival signal via a signal feedback device and transmitted to the control module. The signal processing unit generates an opening command based on this signal, which is then converted into a small current signal by the command distribution unit to drive the execution module. This controls the electromagnetic coil of the locking module to be energized to generate a magnetic field that overcomes the permanent magnet force and unlocks the door. During the closing process, the independent electrical contacts of the safety verification module physically close as the door is locked to the limit position, generating a safety closing signal that triggers the signal processing unit of the control module to verify the door status and generate an elevator operation command, thus making the safety circuit conductive. This ultimately achieves a safety closed loop of "no unlocking without precise leveling and no operation without reliable locking." Through multi-module collaboration and algorithmic decision-making, intelligent judgment and linkage of the entire process from leveling detection and door lock control to safety verification are realized, ensuring operational safety while improving system response efficiency and reliability.

[0008] Secondly, the present invention also provides an elevator-based electric lock control method, which adopts the following technical solution: An elevator-based electric lock control method, applied to the aforementioned electric lock control system, includes: When the elevator is running, the magnetic sensor in the elevator car continuously detects the electromagnetic coil of the lock body until the two are aligned, generating an elevator arrival signal. The control module generates an opening command based on the elevator arrival signal and converts it into a small current signal, which is then transmitted to the execution module. The execution module generates a contact closing action based on a small current signal, generates a large current signal, controls the electromagnetic coil to generate a magnetic field, and cancels or overcomes the permanent magnetic force generated by the permanent magnet in the lock body. Once the permanent magnet force is completely counteracted or overcome, the elevator door latch retracts, the locking module is released, the control module starts the door operator motor to open the elevator door, and disconnects the independent electrical contacts; According to the door closing command or after the delay ends, the control module disconnects or the reverse pulse controls the execution module, the electromagnetic coil is de-energized or generates a reverse magnetic field, and the permanent magnet in the lock body generates permanent magnetic force. The permanent magnet forces push out the latch of the elevator door, activating the locking module. The control module then starts the door operator motor to close the elevator door and triggers the independent electrical contacts. When the independent electrical contacts close, the safety circuit is activated, the safety relay engages, the main running contactor engages, the elevator's control module and braking module are activated, and the elevator begins to run.

[0009] When the elevator is running, the magnetic sensor in the elevator car continuously detects the electromagnetic coil of the lock body until the two are aligned, generating an elevator arrival signal. The specific steps include: When the elevator is running, the magnetic sensor in the elevator car scans the shaft space according to the preset sampling frequency to sense the original magnetic field signal. The original magnetic field signal is filtered and denoised to obtain a stable magnetic field strength, and the rate of change of the magnetic field gradient is calculated. The judgment is made by comparing the magnetic field strength and the magnetic field gradient change rate during elevator operation with the preset intensity range and gradient change range; If both are within the corresponding interval, it is determined that the current elevator is running to the magnetic field space generated by the electromagnetic coil of the lock body, and the elevator is controlled according to the preset stepped speed regulation mechanism until the magnetic sensor and the electromagnetic coil are aligned, generating an elevator arrival signal; The stepped speed regulation mechanism includes: The intensity range and gradient change range are correlated and classified to obtain several levels of intensity thresholds and gradient evolution curves; Based on the elevator's operating speed and the strength difference between the strength thresholds, a layered speed is generated. The rate of change of the stage speed is planned based on the elevator load and the preset running time to obtain the stage acceleration. The elevator position is determined based on the staged acceleration and the gradient evolution curve. If the rate of change of the magnetic field gradient conforms to the gradient evolution curve and the staged acceleration is zero, then the magnetic sensor and the electromagnetic coil are determined to be aligned.

[0010] By adopting the above technical solution, based on state machine control and closed-loop feedback algorithm, the elevator continuously detects the relative position of the lock body electromagnetic coil through the car magnetic sensor during operation. When the two are precisely aligned, an elevator arrival signal is generated. The control module generates an opening command based on this signal and converts it into a small current signal to drive the execution module. The execution module generates a large current through contact closure to control the electromagnetic coil to generate a reverse magnetic field, which precisely counteracts the locking force of the permanent magnet and retracts the latch. Subsequently, the control module starts the door motor to open the door and disconnects the independent electrical contacts. During the closing phase, the control module disconnects the power supply to the execution module according to the command or delay mechanism. An electrical pulse or a reverse pulse is applied to demagnetize the electromagnetic coil, causing the permanent magnet to regain its dominant locking force and push out the latch to complete the mechanical locking. At the same time, it triggers the closure of an independent electrical contact. This contact, as a key node in the safety circuit, directly drives the safety relay and the main operating contactor to engage sequentially, ultimately energizing the control module and the braking module to allow the elevator to run. A state machine algorithm is used to achieve a closed-loop control of the entire chain, including leveling detection, magnetic unlocking, mechanical locking, and safety verification, ensuring the rigid safety logic of "no unlocking if not leveled, no operation if not locked." A current-graded control mechanism reduces energy consumption and improves system reliability.

[0011] Thirdly, the present invention also provides a storage medium storing at least one instruction, at least one program, code set, or instruction set, wherein the at least one instruction, the at least one program, the code set, or instruction set is loaded and executed by a processor to implement the electric lock control method as described above.

[0012] In summary, the beneficial technical effects of the present invention are as follows: By accurately determining the leveling status through electromagnetic induction and combining it with door lock status verification and safety circuit linkage, the elevator is ensured to not operate when the leveling is not accurate from both electrical and mechanical dimensions, which significantly improves the system safety. By coordinating the control module with the control execution module and the door operator motor, an automated process from unlocking, opening to locking is achieved, improving operational efficiency and stability, while simplifying the mechanical structure and enhancing reliability.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Reference Figure 1 The present invention discloses an elevator-based electric lock control system, comprising: The locking module, whose input end is connected to the output end of the execution module, is used to lock or unlock the elevator door; The execution module has its input end connected to the output end of the control module, and is used to control the circuit on and off of the locking module according to the door lock control signal; The control module has a first input terminal connected to the output terminal of the leveling detection module and a second input terminal connected to the output terminal of the safety verification module. It is used to determine the elevator operating status based on the leveling sensing signal, generate the door lock control signal, determine the elevator door status, and control the elevator operating status based on the safety closing signal. The leveling detection module is used to detect and determine the running position of the elevator car, generate the leveling sensing signal, and transmit it to the control module. The safety verification module is used to detect and verify the locking status of the elevator door, generate the safety closing signal, and transmit it to the control module. The locking module is a bistable permanent magnet lock or a monostable permanent magnet lock; the locking module includes a permanent magnet and an electromagnetic coil; the permanent magnet is used to generate permanent magnetic force to lock the elevator door; the electromagnetic coil is used to generate a magnetic field to overcome the permanent magnetic force and unlock the elevator door after being energized; The leveling detection module includes a magnetic sensor and a signal feedback device; the leveling sensing signal includes an elevator arrival signal; if the elevator car moves to the leveling position, the magnetic sensor aligns with the electromagnetic coil of the locking module to generate a magnetic pole sensing signal; the signal feedback device feeds back the elevator arrival signal to the control module based on the magnetic pole sensing signal. The safety verification module includes an independent electrical contact and a safety circuit; the independent electrical contact is connected in series with the safety circuit; if the elevator door is locked to the limit position, the independent electrical contact is triggered to close, generating a safety closing signal, which is then transmitted to the control module. The control module includes: The signal receiving unit is used to receive elevator arrival signals and safety closing signals; The signal processing unit is used to generate an opening command based on the elevator arrival signal, and to determine that the elevator door has been locked based on the safety closing signal, and generate an elevator running command. The instruction distribution unit is used to convert the door opening instruction and the elevator operation instruction into a small current signal and transmit it to the execution module.

[0016] Reference Figure 2 Example 1: The locking module, or locking mechanism, is a mechanical part; it typically includes a lock body consisting of a permanent magnet and an electromagnetic coil. The permanent magnet provides the default locking force (fail-safe), and the magnetic field generated when the electromagnetic coil is energized is used to overcome the permanent magnet force, thus unlocking the lock. This is a "bistable" or "monostable" permanent magnet lock design.

[0017] The leveling detection module, also known as a leveling sensor or magnetic sensor, is installed on the elevator car. When the elevator car reaches the leveling position, this sensor aligns with the electromagnetic coil of the locking mechanism, induces magnetic poles, and sends an "arrival" signal to the elevator controller.

[0018] The safety verification module, or independent electrical contact, is a completely independent electrical contact (usually a microswitch) connected in series in the safety circuit. This contact is only physically triggered to close when the door is mechanically fully locked in place. This is the cornerstone of a reliable safety circuit.

[0019] The control module is an elevator controller used to receive signals from the leveling sensor to determine if the elevator has stopped accurately. It controls the relays that supply power to the door lock solenoid coils based on the direction of travel (open or closed).

[0020] The execution module includes relays / contaminators; it receives small current signals from the controller to control the on / off state of the high-current circuit leading to the door lock solenoid coil.

[0021] The "leveling magnetic pole induction" is merely a trigger signal, informing the controller that "it is time to operate the door lock." The actual locking and unlocking actions are accomplished by the controller energizing the electromagnetic coil via a relay. Whether the door is truly locked is verified by independent electrical contacts.

[0022] The implementation principle of this embodiment is as follows: During elevator operation, the magnetic sensor of the leveling detection module continuously monitors the car's position. When the car reaches the leveling area, the magnetic sensor and the electromagnetic coil of the locking module are precisely aligned to generate a magnetic pole induction signal. The signal feedback device then sends an elevator arrival signal to the control module. After receiving the signal, the signal processing unit of the control module performs logical judgment through a state machine algorithm, generates an opening command, and converts it into a small current control signal transmitted to the execution module by the command distribution unit. The relay of the execution module is activated according to the signal, connecting a large current circuit to generate a reverse magnetic field in the electromagnetic coil of the locking module, precisely counteracting the inherent locking force of the permanent magnet, thus realizing the retraction of the latch and the release of the door lock. Subsequently, the control module starts the door motor to complete the door opening action, while the independent electrical circuit of the safety verification module is activated. The pneumatic contacts disconnect due to mechanical separation. During the door closing phase, the control module disconnects the power supply to the execution module (monostable state) or applies a reverse pulse (bistable state) according to the instruction or delay setting, causing the electromagnetic coil to demagnetize. The permanent magnet regains its dominant position and pushes the latch to complete the mechanical locking. This process simultaneously triggers the closure of independent electrical contacts, generating a safety closing signal that is fed back to the control module. After verifying the signal, the control module generates an elevator operation instruction, making the independent electrical contacts connected in series in the safety circuit the key to conduction. Ultimately, this drives the safety relay and the main running contactor to engage sequentially, achieving rigid safety protection of "no unlocking without precise alignment at non-leveling floors and no connection of the safety circuit without mechanical locking in place." The entire system ensures high reliability and fault-tolerant characteristics of elevator start-stop and door lock operation through multi-module collaboration and closed-loop control.

[0023] Reference Figure 3 An elevator-based electric lock control method, applied to the elevator-based electric lock control system, includes: When the elevator is running, the magnetic sensor in the elevator car continuously detects the electromagnetic coil of the lock body until the two are aligned, generating an elevator arrival signal. The control module generates an opening command based on the elevator arrival signal and converts it into a small current signal, which is then transmitted to the execution module. The execution module generates a contact closing action based on a small current signal, generates a large current signal, controls the electromagnetic coil to generate a magnetic field, and cancels or overcomes the permanent magnetic force generated by the permanent magnet in the lock body. Once the permanent magnet force is completely counteracted or overcome, the elevator door latch retracts, the locking module is released, the control module starts the door operator motor to open the elevator door, and disconnects the independent electrical contacts; According to the door closing command or after the delay ends, the control module disconnects or the reverse pulse controls the execution module, the electromagnetic coil is de-energized or generates a reverse magnetic field, and the permanent magnet in the lock body generates permanent magnetic force. The permanent magnet forces push out the latch of the elevator door, activating the locking module. The control module then starts the door operator motor to close the elevator door and triggers the independent electrical contacts. When the independent electrical contacts close, the safety circuit is activated, the safety relay engages, the main running contactor engages, the elevator's control module and braking module are activated, and the elevator begins to run.

[0024] In this embodiment, when the elevator is running, the magnetic sensor of the elevator car continuously detects the electromagnetic coil of the lock body until the two are aligned, and the specific steps for generating an elevator arrival signal include: When the elevator is running, the magnetic sensor in the elevator car scans the shaft space according to the preset sampling frequency to sense the original magnetic field signal. The original magnetic field signal is filtered and denoised to obtain a stable magnetic field strength, and the rate of change of the magnetic field gradient is calculated. The judgment is made by comparing the magnetic field strength and the magnetic field gradient change rate during elevator operation with the preset intensity range and gradient change range; If both are within the corresponding interval, it is determined that the current elevator is running to the magnetic field space generated by the electromagnetic coil of the lock body, and the elevator is controlled according to the preset stepped speed regulation mechanism until the magnetic sensor and the electromagnetic coil are aligned, generating an elevator arrival signal; The stepped speed regulation mechanism includes: The intensity range and gradient change range are correlated and classified to obtain several levels of intensity thresholds and gradient evolution curves; Based on the elevator's operating speed and the strength difference between the strength thresholds, a layered speed is generated. The rate of change of the stage speed is planned based on the elevator load and the preset running time to obtain the stage acceleration. The elevator position is determined based on the staged acceleration and the gradient evolution curve. If the rate of change of the magnetic field gradient conforms to the gradient evolution curve and the staged acceleration is zero, then the magnetic sensor and the electromagnetic coil are determined to be aligned.

[0025] The implementation principle of this embodiment is as follows: When the elevator is running, the car magnetic sensor scans the shaft space at a preset frequency and collects the original magnetic field signal. After filtering and noise reduction, the stable magnetic field strength and gradient change rate are extracted and compared in real time with the preset strength range and gradient change range. When the signal parameters simultaneously meet the dual range conditions, the system determines that the elevator has entered the effective magnetic field space of the electromagnetic coil and then starts the stepped speed regulation mechanism. This mechanism dynamically generates a step-by-step speed and corresponding step-by-step acceleration by associating the graded strength threshold and gradient evolution curve with the current running speed and load, driving the elevator to perform progressive and precise positioning. Finally, when the magnetic field gradient change rate completely matches the preset evolution curve and the step-by-step acceleration returns to zero, the system confirms that the magnetic sensor and the electromagnetic coil have reached a spatial alignment state and generates a highly reliable elevator arrival signal, thereby realizing the full-process adaptive closed-loop control from coarse positioning to fine alignment. Example

[0026] When the elevator is running, the car's magnetic sensor approaches the door lock's electromagnetic coil (usually installed on the door device); when the two are aligned, the electromagnetic coil's magnetic poles are induced, and a signal is sent to the elevator controller (MCU); the MCU determines that the elevator has leveled and stopped. After the MCU confirms that the door has stopped and there is no fault, it issues an "open door" command; the door opening relay (KOpen) coil is energized and engages. When the contacts of KOpen close, power is supplied to the electromagnetic coils of all door locks with a specific polarity; the magnetic field generated by the electromagnetic coils cancels or overcomes the locking force of the permanent magnet, the latch retracts, and the door lock is released from mechanical locking. The MCU simultaneously starts the door motor to open the door; after the door is opened, the mechanical structure disconnects the door status verification contact. Upon receiving the door closing command or after the delay period, the MCU starts the door motor to close the door, and the door moves into position. The MCU disconnects the door open relay (KOpen) and may briefly energize the door close relay (KClose) (by providing a reverse pulse or simply de-energizing, depending on the lock design). When the electromagnetic coil is de-energized (or generates a reverse magnetic field), the magnetic force of the permanent magnet dominates, pushing out the latch to complete the mechanical locking. The mechanical action of locking the door leaf physically triggers the door status verification contact (normally open → closed). The closure of an independent electrical contact is a prerequisite for the conduction of a safety circuit, and this contact is connected in series with all other safety switches (emergency stop, speed limiter, etc.) to form a safety circuit; The entire safety circuit is activated, energizing the coil of the safety relay (KAS); the contacts of the KAS control the coil circuit of the main operating contactor.

[0027] When the main operating contactor engages, the elevator drive unit and brake are energized, and the elevator is allowed to run.

[0028] The implementation principle of this embodiment is as follows: During elevator operation, the car's magnetic sensor continuously detects the position of the door lock electromagnetic coil. When the two are precisely aligned, a magnetic pole induction signal is generated and sent to the MCU. Based on this, the MCU determines that the elevator has leveled and stopped, and then issues an opening command, causing the door opening relay KOpen coil to be energized and attracted. After its contacts close, a power supply of a specific polarity is connected to the door lock electromagnetic coil. The generated magnetic field precisely counteracts the locking force of the permanent magnet, retracting the latch and releasing the mechanical lock. At the same time, the MCU starts the door motor to complete the door opening action and opens the door status verification contact. During the closing phase, the MCU starts according to the command or delay setting. The door operator motor drives the door to close completely. Then, KOpen is disconnected, and depending on the lock type, a reverse pulse is sent to the closing relay KClose to de-energize the electromagnetic coil or generate a reverse magnetic field. The permanent magnet then drives the latch to complete the mechanical locking. This mechanical action physically triggers the door status verification contact to change from normally open to closed. The closure of this contact is the core prerequisite for the safety circuit to be connected. It is connected in series with safety switches such as emergency stop and speed governor to form a complete circuit. Its conduction energizes the safety relay KAS coil, which in turn controls the main running contactor to engage through the KAS contact, ultimately energizing the elevator drive unit and brake.

[0029] The present invention also provides a storage medium storing at least one instruction, at least one program, code set, or instruction set, wherein the at least one instruction, the at least one program, the code set, or the instruction set is loaded and executed by a processor to implement the electric lock control method as described above.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
