Description

Technical Field

[0001] The present invention relates to the technical field of elevator shaft lighting, and in particular to a shaft lighting system based on group control & parallel SCL communication control. Background Art

[0002] In the field of elevator shaft lighting control technology, traditional technologies have many defects that need to be solved. First, when the power supply fails, the existing communication device for controlling shaft lighting will consume additional backup battery power due to the lack of an effective power management strategy. In order to maintain its normal operation, it is necessary to add power detection and control devices, or increase the capacity of the backup battery, which undoubtedly directly leads to a significant increase in costs. Second, in the scenario where the power supply is restored after a power outage, the shaft lighting cannot remember the state before the power outage. In particular, when it is off before the power outage, it may light up automatically after the power is restored. This uncontrollability brings great inconvenience to engineering maintenance operations, and during the frequent operation of the elevator, unnecessary lighting will increase the power consumption of the elevator to a certain extent, which is not conducive to the overall energy-saving operation of the elevator. Third, the traditional five-party intercom communication device has inherent disadvantages in signal transmission. It generally uses analog signal transmission, or needs to decode the analog audio signal into a digital signal. In this process, the analog signal transmission link and the decoding conversion link are very susceptible to power interference, which in turn causes the shaft lighting to malfunction, seriously affecting the accuracy and reliability of the shaft lighting control. Fourth, the communication transmission distance of the five-party intercom communication device is relatively limited. When the elevator is lifted to a large height (for example, more than 300 meters), communication failures often occur, making it impossible to effectively control the shaft lighting, which greatly limits its application in high-rise elevators. Fifth, the traditional operation method requires the operator to open the first floor door and touch the operating device to operate the shaft lighting. This operation mode is not only extremely inconvenient, but also when the operator opens the floor door to operate, there is a high risk of falling, which poses a serious threat to the personal safety of the operator. Sixth, the failure rate of the five-party intercom communication device itself is relatively high. Frequent failures will inevitably lead to an increase in the maintenance frequency of the elevator shaft lighting, thereby significantly increasing the maintenance cost and bringing a heavy burden to the maintenance and management of the elevator. Summary of the invention

[0003] The purpose of the present invention is to provide a shaft lighting system based on group control & parallel SCL communication control, to build a complete and coordinated shaft lighting control system architecture, to achieve centralized and intelligent control of shaft lighting through the organic integration of key components, to lay the foundation for the stable operation of the entire system, and to improve the convenience and efficiency of elevator shaft lighting management; the reasonable layout of the operation unit outside the hall and the operation unit inside the car enables the operator to conveniently control the shaft lighting whether preparing to enter the shaft for operation outside the elevator or performing maintenance work in the car, which greatly improves the operational flexibility and reduces the operation delays caused by inconvenient operation. The SCL communication devices of the control system and the group management system are interconnected, ensuring that the shaft lighting can still be effectively controlled in different elevator operating states and fault conditions, enhancing the reliability and fault tolerance of the entire system, and reducing the risk of lighting out of control due to local faults.

[0004] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a shaft lighting system based on group control & parallel SCL communication control, mainly composed of a power supply, a group management system power supply unit, an elevator control system power supply unit, a group management system, an elevator control system, an SCL communication device, a shaft lighting device, an outside hall operation unit, an inside car operation unit and a control unit.

[0005] The outside hall operation unit is installed outside the elevator stop hall to facilitate the operator to perform lighting operations before entering the hoistway or exiting the pit.

[0006] The in-car operating unit is located in the elevator car, which makes it easy for people in the car to collaborate with people in other locations to control the shaft lighting.

[0007] The SCL communication device undertakes the key task of transmitting signals between the operating unit outside the hall, the operating unit inside the car and the control system or group management system to ensure the accurate transmission of information.

[0008] The control unit is independently arranged near the control system, group management system and power supply unit. This layout is conducive to simplifying the circuit and facilitating the wiring of the control circuit, thereby improving the stability and maintainability of the system.

[0009] The SCL communication devices of the control system and the group management system are interconnected. As long as the control system or group management system of any elevator works normally, the SCL communication device can ensure the normal control of the shaft lighting, greatly improving the fault tolerance and reliability of the system.

[0010] As a further improvement of the technical solution of the present invention, the SCL communication device includes a group management system communication device and an elevator control system communication device. The group management system communication device can coordinate the shaft lighting related information of multiple elevators to achieve optimal allocation and centralized management of resources; the elevator control system communication device focuses on the lighting control details of a single elevator. The two work together to improve the coordination and accuracy of the entire system.

[0011] Wired transmission or wireless transmission can be used. Wired transmission uses high-quality shielded cables to connect various components according to a carefully planned line layout, which can provide stable and reliable signal transmission and is suitable for scenarios with extremely high requirements for signal stability; wireless transmission uses advanced wireless communication technologies, such as Bluetooth low energy, ZigBee or wireless radio frequency technology in a specific frequency band, to build a flexible communication network in the complex environment of the elevator shaft, reducing wiring costs and difficulties, and giving the system greater scalability.

[0012] It has powerful signal interference shielding and isolation capabilities. By combining hardware circuit design (such as filters, shielding covers, etc.) with software algorithms (such as signal error correction, encrypted transmission, etc.), it can effectively resist power supply interference and interference from other complex electromagnetic environments in the shaft, ensure the accurate transmission of shaft lighting control signals, eliminate lighting malfunctions caused by interference, and ensure the accuracy and stability of elevator shaft lighting control. Its communication transmission distance can reach 1,000 meters, which is enough to meet the requirements of various elevator lifting heights. Whether it is ordinary high-rise buildings or super high-rise buildings, elevator shaft lighting control can achieve stable and efficient signal transmission, which greatly broadens the scope of application of the present invention.

[0013] Outside hall operation unit and inside car operation unit:

[0014] The operation units outside the hall and inside the car have various forms. They can be in the form of traditional buttons and switches, which are simple and intuitive to operate, easy to understand and use; they can also be touch-type and inductive devices, with rich and diverse signal categories, including but not limited to pulse, waveform, voice, sound and other induction, touch, QR code and other forms. For example, the inductive device can adopt the proximity sensing principle, and automatically activate the operation interface when the maintenance personnel approach, which is convenient and fast; in the voice control mode, the operator only needs to say a specific command, such as "turn on the shaft lighting", and the operation unit can quickly capture the voice signal and send the corresponding operation signal through the SCL communication terminal, which greatly improves the convenience and intelligence of the operation, is suitable for different scenarios and user habits, and improves the human-computer interaction friendliness and applicability of the system.

[0015] Control unit:

[0016] The control unit can be an I / O port, a transistor, a thyristor, or a control circuit or control device built for this purpose. The I / O port is simple to use and low cost, suitable for scenes with low control requirements; transistors and thyristors have fast switching characteristics and high control accuracy, which can meet complex lighting control requirements; and customized control circuits or control devices can be optimized according to the special requirements of the specific elevator shaft lighting system, improving the overall performance and adaptability of the system and reducing the cost of system construction and maintenance difficulty.

[0017] As a further improvement of the technical solution of the present invention, the control principle of the present invention is:

[0018] As the components of hall call and car call, the hall operation unit and car operation unit send hall operation signals and car operation signals through the SCL communication terminal. For example, when the operator presses the button of the hall operation unit or triggers the inductive device of the car operation unit, the corresponding operation signal is generated and transmitted.

[0019] The SCL communication device receives the above signal and transmits it to the control system or group management system for processing. During the transmission process, the SCL communication device uses its strong anti-interference ability to ensure the integrity and accuracy of the signal.

[0020] After the control system or group management system processes the operation signal, the drive component outputs the control signal to drive the control unit. This process involves complex logical judgment and signal conversion, such as determining whether to turn on or off the lighting unit based on the current operating status of the elevator, lighting requirements, and preset control strategies.

[0021] The control unit controls the lighting and extinguishing of the lighting unit according to the received signal. Taking transistor control as an example, when a signal to light up the lighting unit is received, the transistor is quickly turned on to provide a stable current path for the lighting unit, making it light up instantly; and when a signal to turn off is received, the transistor is quickly turned off to cut off the current supply.

[0022] Power supply circuit & control circuit solution:

[0023] The power supply supplies power to the shaft lighting device, the elevator control system power supply unit, and the group management system power supply unit, providing stable power support for the entire system.

[0024] The elevator control system power supply unit supplies power to the elevator control system independently; the group management system power supply unit supplies power to the group management system independently. This independent power supply method helps to improve the stability and maintainability of the system.

[0025] When the elevator control system power supply unit ① is powered normally, the SCL communication device is powered by the elevator control system ①. After operating the operation unit ① outside the hall or the operation unit ① inside the car, the SCL communication device transmits a signal, the elevator control system ① outputs a drive control unit ① signal, and the control unit executes the action of component ①, thereby controlling the lighting unit ① to light up or go out.

[0026] When the elevator control system power supply unit ② is powered normally, the SCL communication device is powered by the elevator control system No. ②. After operating the operation unit ② outside the hall or the operation unit ② inside the car, the SCL communication device transmits a signal, the elevator control system ② outputs a drive control unit ② signal, and the control unit executes the action of component ②, thereby controlling the lighting unit ② to light up or go out.

[0027] When the power supply unit ① of the elevator control system is powered off, the SCL communication device is powered by the elevator control system ② or the group management system. After operating the operation unit ① outside the hall or the operation unit ① inside the car, the SCL communication device transmits a signal, the elevator control system ② outputs a signal to drive the control unit ①, and the control unit executes the action of component ①, thereby controlling the lighting unit ① to light up or go out.

[0028] When the power supply unit ② of the elevator control system is powered off, the SCL communication device is powered by the elevator control system No. ① or the group management system. After operating the operation unit ② outside the hall or the operation unit ② inside the car, the SCL communication device transmits a signal, and the elevator control system ① outputs a signal to drive the control unit ②, and the control unit executes the action of component ②, thereby controlling the lighting unit ② to light up or go out.

[0029] When the elevator control system power supply units ① and ② are powered off at the same time, the SCL communication device is powered by the group management system. After operating the operation units ① and ② outside the hall or the operation units ① and ② inside the car, the SCL communication device transmits signals, and the elevator control system ① and ② output drive control unit ① and ② signals, and the control unit executes the actions of components ① and ②, thereby controlling the lighting units ① and ② to light up or go out. This design of the power supply circuit and control circuit realizes redundant backup and intelligent switching of the power supply, ensuring that the shaft lighting can work normally under various power supply conditions, and improving the power supply reliability and stability of the entire system.

[0030] As a further improvement of the technical solution of the present invention, the system configuration flexibility of the present invention is:

[0031] In the system of the present invention, two elevators in parallel are a basic and necessary configuration. In this configuration, the control systems and SCL communication devices of the two elevators cooperate with each other, which can give full play to the advantages of parallel elevators in resource sharing and improved operating efficiency. For example, when one elevator is idle and the other elevator is running and its shaft lighting is operated, the resources of the idle elevator can be shared, such as the SCL communication device can help share the signal transmission task, improve the response speed and reliability of the entire system, while reducing system costs and energy consumption, and facilitate unified management and scheduling in multi-elevator scenarios.

[0032] Or a configuration of one elevator and a similar group management system can be used. In this alternative configuration, the group management system assumes the role of overall coordination and performs refined management of the shaft lighting control of a single elevator, which can also achieve the functional effects of the above-mentioned system, that is, to achieve functional characteristics such as control of shaft lighting based on group control & parallel SCL communication, ensure the stability and reliability of lighting control, and cope with lighting needs under various working conditions. This flexible configuration method provides a variety of solutions for elevator shaft lighting systems of different scales and needs, improves the applicability and scalability of the invention, and can find suitable configuration solutions for both small elevator projects and large and complex elevator groups, reducing system construction and maintenance costs.

[0033] Compared with the traditional technology, the present invention has the following significant beneficial effects:

[0034] When the power supply fails, the communication device that controls the shaft lighting also loses power, effectively avoiding the extra consumption of the backup battery. There is no need to add complex control circuits and additional power detection and control devices, which significantly reduces costs.

[0035] With the help of the power-off holding device in the elevator control system, when the power supply is restored after a power outage, the shaft lighting can be accurately maintained in the state before the power outage, which greatly facilitates engineering maintenance operations, reduces unnecessary lighting energy consumption, and effectively promotes energy saving of elevators.

[0036] The elevator SCL communication device used is specially designed for elevator communication. It has powerful signal interference shielding and isolation capabilities, effectively resists power supply interference, and prevents the occurrence of misoperation of shaft lighting, greatly improving product performance and control accuracy.

[0037] The SCL communication device has a communication transmission distance of up to 1,000 meters, which is sufficient to meet the lifting height requirements of various types of elevators. Whether it is a high-rise elevator or an ultra-high-rise elevator, it can ensure stable control of the shaft lighting, significantly broadening the application scope of the product.

[0038] Operators can conveniently operate the shaft lighting outside the hall or inside the car without opening the first-floor door to access the operating device, completely eliminating the risk of falling caused by opening the floor door, greatly improving the convenience and safety of operation.

[0039] The SCL communication device has the characteristics of long life cycle, high stability and is not easy to damage. It effectively reduces the maintenance frequency and maintenance cost of elevator shaft lighting, and reduces the difficulty and cost of elevator maintenance management.

[0040] The SCL communication device has good scalability and can more conveniently realize the diversified expansion of shaft lighting control functions. It does not require complex architecture adjustments during the design process and is low-cost, providing strong support for the upgrade and optimization of elevator shaft lighting systems.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0051] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0052] See also Figures 1 to 5 , the present invention provides a technical solution: a shaft lighting system based on group control & parallel SCL communication control, including a power supply, a group management system power supply unit, an elevator control system power supply unit, a group management system, an elevator control system, an SCL communication device, a shaft lighting device, an outside hall operation unit, an inside car operation unit and a control unit;

[0053] The power supply is electrically connected to the group management system through the group management system power supply unit; the power supply is electrically connected to the elevator control system through the elevator control system power supply unit; the power supply is electrically connected to the shaft lighting device;

[0054] The hall operation unit is arranged outside the hall of the elevator stop station, and the car operation unit is arranged inside the elevator car. The SCL communication device transmits the signals of the hall operation unit and the car operation unit to the elevator control system or the group management system; the control unit is independently arranged near the control system, the group management system, and the power supply unit to simplify the circuit and facilitate the control circuit wiring; the elevator control system or the group management system performs signal processing and outputs the signal driving the control unit; the control unit controls the lighting and extinguishing of the shaft lighting device;

[0055] The SCL communication device of the elevator control system and the SCL communication device of the group management system are interconnected, so that when the control system or the group management system of any elevator is working normally, the SCL communication device can normally control the shaft lighting.

[0056] The present invention constructs a complete and coordinated shaft lighting control system architecture. Through the organic integration of key components (power supply, group management system power supply unit, elevator control system power supply unit, group management system, elevator control system, SCL communication device, shaft lighting device, outside hall operation unit, inside car operation unit and control unit), the centralized and intelligent control of shaft lighting is realized, which lays the foundation for the stable operation of the whole system and improves the convenience and efficiency of elevator shaft lighting management.

[0057] The reasonable layout of the operating unit outside the hall and inside the car enables the operator to conveniently control the shaft lighting whether he is preparing to enter the shaft for operation outside the elevator or performing maintenance work in the car, which greatly improves the operational flexibility and reduces the operation delays caused by inconvenient operation.

[0058] The interconnection of the SCL communication devices of the control system and the group management system ensures that the shaft lighting can still be effectively controlled in different elevator operating states and fault conditions, enhancing the reliability and fault tolerance of the entire system and reducing the risk of lighting out of control due to local faults.

[0059] Specifically, in this embodiment, the SCL communication device includes a group management system communication device and an elevator control system communication device. It should be noted that the SCL communication device clearly includes a group management system communication device and an elevator control system communication device, which realizes accurate and fast interaction of information between different system levels. The group management system communication device can coordinate the shaft lighting requirements and status information of multiple elevators, while the elevator control system communication device focuses on the fine control of a single elevator. The two work together to improve the coordination and accuracy of the shaft lighting control of the entire elevator group, optimize the allocation of lighting resources, and avoid energy waste.

[0060] Specifically, in this embodiment, the shaft lighting device includes a machine room operation unit and a lighting unit. It should be noted that the shaft lighting device is subdivided into a machine room operation unit and a lighting unit. The machine room operation unit facilitates centralized management and monitoring of the shaft lighting at the machine room end, and timely discovers and handles problems such as lighting failures; the lighting unit focuses on providing effective lighting in the shaft. This subdivision helps to improve the maintenance convenience and operation stability of the shaft lighting system, reduce maintenance costs and time, ensure that the elevator shaft is always in a good lighting environment, and improve the safety of elevator operation.

[0061] Specifically, in this embodiment, the hall operation unit and the car operation unit are components of hall call and car call, and the hall operation signal and the car operation signal are sent through the SCL communication terminal of the SCL communication device; the SCL communication device receives the hall operation signal and the car operation signal and transmits them to the elevator control system or group management system for processing; the elevator control system or group management system processes the operation signal, and then the driving component outputs a control signal to drive the control unit; the control unit controls the lighting and extinguishing of the lighting unit according to the received signal. It should be noted that based on the control principle of group control & parallel SCL communication, the hall operation unit and the car operation unit are used as components of hall call and car call to send operation signals, which are transmitted to the control system or group management system for processing by the SCL communication device, and then the driving component outputs a control signal to drive the control unit, and finally realizes the lighting and extinguishing control of the lighting unit. This hierarchical and multi-link control process design makes the shaft lighting control more accurate and reliable, and can be intelligently adjusted according to different operation requirements and elevator operation status, improve the automation degree and energy utilization efficiency of the lighting system, and reduce the risk of human error.

[0062] Specifically, in the present embodiment, the power supply supplies power to the shaft lighting device, the elevator control system power supply unit, and the group management system power supply unit;

[0063] The elevator control system power supply unit supplies power to the elevator control system alone, and the group management system power supply unit supplies power to the group management system alone;

[0064] When the power supply unit ① of the elevator control system is powered normally, the SCL communication device is powered by the elevator control system ①. After operating the operation unit ① outside the hall or the operation unit ① inside the car, the SCL communication device transmits a signal, the elevator control system ① outputs a signal to drive the control unit ①, and the control unit executes the action of component ①, thereby controlling the lighting unit ① to light up or go out;

[0065] When the elevator control system power supply unit ② is powered normally, the SCL communication device is powered by the elevator control system ②. After operating the operation unit ② outside the hall or the operation unit ② inside the car, the SCL communication device transmits a signal, the elevator control system ② outputs a signal to drive the control unit ②, and the control unit executes the action of component ②, thereby controlling the lighting unit ② to light up or go out;

[0066] When the power supply unit ① of the elevator control system is powered off, the SCL communication device is powered by the elevator control system ② or the group management system. After operating the operation unit ① outside the hall or the operation unit ① inside the car, the SCL communication device transmits a signal, the elevator control system ② outputs a signal to drive the control unit ①, and the control unit executes the action of component ①, thereby controlling the lighting unit ① to light up or go out;

[0067] When the power supply unit ② of the elevator control system is powered off, the SCL communication device is powered by the elevator control system ① or the group management system. After operating the operation unit ② outside the hall or the operation unit ② inside the car, the SCL communication device transmits a signal, the elevator control system ① outputs a signal to drive the control unit ②, and the control unit executes the action of component ②, thereby controlling the lighting unit ② to light up or go out;

[0068] When the power supply units ① and ② of the elevator control system are powered off at the same time, the SCL communication device is powered by the group management system. After operating the operation units ① and ② outside the hall or the operation units ① and ② inside the car, the SCL communication device transmits a signal, and the elevator control system ① and ② outputs the drive control unit ① and ② signal, and the control unit executes the action of components ① and ②, thereby controlling the lighting units ① and ② to light up or go out. It should be noted that the carefully designed power supply circuit & control circuit scheme can ensure the coordinated work between the SCL communication device, the control unit and the lighting unit under the power supply status (normal power supply, power off) of different elevator control system power supply units. For example, when a power supply unit of an elevator control system is powered off, it can automatically switch to another elevator control system or group management system for power supply, ensuring that the shaft lighting operation is not affected, realizing redundant backup and intelligent switching of the power supply, improving the power supply reliability and stability of the entire system, reducing the probability of lighting out of control due to power supply failure, and ensuring the continuous availability of elevator shaft lighting under various working conditions.

[0069] Specifically, in the present embodiment, the system adopts a configuration of two elevators in parallel, which is a basic and necessary structural form. Under this configuration, the various components work together to achieve effective control of the shaft lighting; or a combination of one elevator and a similar group management system is adopted. Under this alternative configuration, the functional effects of the above system can also be achieved, that is, the control of the shaft lighting based on group control & parallel SCL communication, the stability and reliability of the lighting control, and the lighting requirements under various working conditions can be achieved. It should be noted that the system adopts a configuration of two elevators in parallel, which is a basic and necessary structural form. Under this configuration, the various components work together to achieve effective control of the shaft lighting, which can give full play to the advantages of parallel elevators in resource sharing and operation efficiency improvement, reduce system costs and energy consumption, improve the response speed and stability of shaft lighting control, and facilitate unified management and scheduling in multi-elevator scenarios. Or a combination of an elevator and a similar group management system can be used. Under this alternative configuration, the functional effects of the above system can also be achieved, that is, the control of shaft lighting based on group control & parallel SCL communication, the stability and reliability of lighting control, and the lighting requirements under various working conditions can be achieved. This flexible configuration method provides a variety of solutions for elevator shaft lighting systems of different scales and needs, improves the applicability and scalability of the invention, and can find suitable configuration solutions for both small elevator projects and large and complex elevator groups, reducing system construction and maintenance costs.

[0070] Specifically, in this embodiment, the operation unit outside the hall and the operation unit inside the car are one or more of a button, a switch, a pulse generator, a waveform generator, a voice recognition device, a sound sensor, a sensing device, a touch device or a QR code scanning device. It should be noted that the diversified forms of the operation unit outside the hall and the operation unit inside the car (which can be a button, a switch, or a touch-type, inductive device, and the signal categories include but are not limited to pulses, waveforms, voices, sounds, etc., inductive, touch, QR code, etc.) provide the operator with a wealth of operation options. Different forms are suitable for different scenarios and user habits. For example, in special environments or emergency situations, inductive devices can realize non-contact fast operation, improve operation efficiency and safety; and multiple signal categories can expand the operation function, such as voice control can be convenient for special groups to use, and improve the human-computer interaction friendliness and applicability of the system.

[0071] Specifically, in this embodiment, the SCL communication device is one or more of an elevator status detection communication device, a monitoring communication device, an elevator debugging communication tool, a remote monitoring communication system, or a wireless connection terminal device.

[0072] Specifically, in this embodiment, the SCL communication device adopts wired transmission or wireless transmission; the communication transmission distance is at least 1000 meters. It should be noted that the elevator SCL communication device can adopt wired transmission or wireless transmission. Wired transmission ensures the stability and reliability of signal transmission, and is suitable for scenes with high requirements for signal interference or short transmission distance; wireless transmission gives the system greater flexibility and scalability, which is convenient for equipment layout and system upgrade in the complex environment of the elevator shaft, reducing wiring costs and difficulties. Its signal interference shielding and isolation measures can effectively resist power supply interference and other complex electromagnetic environments in the shaft, ensure the accurate transmission of shaft lighting control signals, eliminate lighting malfunctions caused by interference, ensure the accuracy and stability of elevator shaft lighting control, and improve the safety and reliability of the overall operation of the elevator. The communication transmission distance of up to 1000 meters can meet the requirements of most elevator lifting heights. Whether it is an ordinary high-rise building or a super high-rise building, the elevator shaft lighting control can achieve stable and efficient signal transmission, which greatly broadens the scope of application of the present invention and enhances the versatility and adaptability of the product.

[0073] Specifically, in the present embodiment, the control unit is one or more of an I / O port, a transistor, a thyristor, a control circuit or a control device for this purpose. It should be noted that the control unit can be in various forms (I / O port, transistor, thyristor, or a control circuit or control device built for this purpose), and different forms of control units have their own advantages in terms of cost, response speed, control accuracy, etc. For example, the I / O port is simple and easy to use, low cost, and suitable for scenarios with low control requirements; transistors and thyristors have fast switching characteristics and high control accuracy, which can meet complex lighting control requirements; and customized control circuits or control devices can be optimized according to the special requirements of the specific elevator shaft lighting system, so as to improve the overall performance and adaptability of the system and reduce the cost of system construction and maintenance difficulty.

[0074] Specifically, in the actual application of the shaft lighting system based on group control & parallel SCL communication control, the components work together to achieve efficient and stable shaft lighting control.

[0075] First of all, the off-hall operation unit is precisely placed in a prominent position outside the hall of each elevator stop, and its design fully considers ergonomics and ease of operation. Whether it is a button, switch, or touch-type or inductive device (such as the inductive type can use the proximity sensing principle to automatically activate the operation interface when the maintenance personnel approach), it allows maintenance personnel to easily pre-control the shaft lighting before entering the shaft. The in-car operation unit is cleverly arranged in an easily accessible place in the elevator car, such as setting a special lighting control area in a conspicuous corner of the car operation panel. Its various operation forms (including pulse, waveform, voice, sound, etc., touch, QR code, etc.) enable maintenance personnel or passengers in the car to easily cooperate with personnel in other positions (such as the top of the car, outside the hall without an operation unit) to control the shaft lighting under specific needs. For example, in voice control mode, passengers only need to say a specific command, such as "turn on the shaft lighting", and the in-car operation unit can quickly capture the voice signal and send the corresponding operation signal through the SCL communication terminal.

[0076] As the key bridge for signal transmission of the entire system, the SCL communication device can flexibly choose wired or wireless transmission methods according to the actual elevator shaft environment and needs. In wired transmission, high-quality shielded cables are used to accurately connect the operation unit outside the hall, the operation unit inside the car and the control system or group management system according to the pre-planned line layout to ensure the stability and anti-interference of signal transmission. If wireless transmission is used, advanced wireless communication technologies such as Bluetooth low energy, ZigBee or wireless radio frequency technology in a specific frequency band are used to build a reliable wireless communication network in the limited space of the elevator shaft. Its powerful signal interference shielding and isolation measures are achieved by combining hardware circuit design (such as filters, shielding covers, etc.) with software algorithms (such as signal error correction, encrypted transmission, etc.). When encountering power fluctuations or other electromagnetic interference, it can effectively filter out clutter to ensure that the operation signal is accurately transmitted to the control system or group management system.

[0077] The control unit can take different forms (I / O port, transistor, thyristor or customized control circuit, control device), and after receiving the control signal output by the driving component from the control system or group management system, it can quickly and accurately perform the corresponding action. Taking transistor control as an example, when receiving the signal to light up the lighting unit, the transistor quickly turns on, providing a stable current path for the lighting unit, making it light up instantly; and when receiving the extinguishing signal, the transistor quickly turns off, cutting off the current supply.

[0078] For the power supply circuit & control circuit, the power supply stably supplies power to the shaft lighting device, the elevator control system power supply unit, and the group management system power supply unit. During normal operation, if the elevator control system power supply unit ① is powered normally, the SCL communication device is powered by the elevator control system No. ①. At this time, if the operation unit ① outside the hall or the operation unit ① inside the car is triggered, the operation signal is quickly transmitted to the elevator control system ① through the SCL communication device. After the internal logic processing of the elevator control system ①, the drive component outputs the signal of the drive control unit ①, and the control unit ① executes the action of component ①, thereby accurately controlling the lighting unit ① to light up or go out. When the elevator control system power supply unit ① loses power, the system automatically switches to the power supply of the elevator control system No. ② or the group management system. The subsequent operation process is similar to that of normal power supply, except that the power supply source changes. The whole process is seamlessly connected to ensure that the shaft lighting is not affected by the failure of the power supply unit.

[0079] In the configuration of two elevators in parallel, the control systems and SCL communication devices of the two elevators cooperate with each other. For example, when one elevator is idle and the other elevator is running and its shaft lighting is operated, the resources of the idle elevator can be shared, such as the SCL communication device can help share the signal transmission task, improving the response speed and reliability of the entire system. In the configuration of one elevator and a similar group management system, the group management system assumes the role of overall coordination and performs refined management of the shaft lighting control of a single elevator. It can also achieve similar functional effects as the parallel configuration, ensuring that the shaft lighting can be effectively controlled under various working conditions, meeting the needs of different elevator application scenarios, and providing a stable, intelligent and energy-saving solution for elevator shaft lighting.

[0080] In summary, the shaft lighting system based on group control & parallel SCL communication control of the present invention targets the pain points of traditional technologies, and comprehensively overcomes many difficulties in traditional elevator shaft lighting control technology through innovative system architecture, unique component design, scientific control principles and circuits, and flexible configuration methods. It not only effectively improves the stability, reliability, and energy saving of shaft lighting control, but also greatly reduces costs, significantly improves applicability and scalability, and brings a revolutionary change to the field of elevator shaft lighting. It is expected to be widely used in various elevator shaft lighting needs, leading elevator shaft lighting technology into a brand new future.
