Description

Technical Field

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

[0002] The existing elevator shaft lighting adopts the method of laying through the elevator shaft, which is mainly composed of 220V power supply, circuit breaker, circuit protection (FUSE), cables / wires, wire ducts, lamps, rocker switches and other devices. The lighting is controlled by the rocker switch. Figure 6 Among them, ① is 220V power supply, ② is circuit breaker, ③ is FUSE, ④ is cable / wire, ⑤ is wire duct, ⑥ is shaft light, and ⑦ is rocker switch; shaft lighting must meet the requirements of GB / T 7588.1: "It can be controlled in both the elevator machine room and the pit, and the control device can be a switch or its equivalent device", so the existing circuit needs to add serial number ④ cable / wire and ⑦ rocker switch to achieve shaft lighting in "both the elevator machine room and the pit can be controlled". However, this traditional shaft lighting technology has many defects:

[0003] First, when realizing dual control of lighting in both the machine room and the pit, additional cables and switches are required, which directly leads to a significant increase in material and installation costs. Secondly, its control method is extremely simple, relying only on simple rocker switches, which is difficult to adapt to the development trend of modern elevator intelligent control and cannot meet the needs of intelligent buildings for diversified elevator functions. Summary of the invention

[0004] The purpose of the present invention is to provide a shaft lighting system based on communication channel control, which multiplexes the communication channel with the shaft lighting circuit and integrates cables to achieve dual / multi-link control. Compared with the traditional dual-link control method that requires the addition of cables and switches, it effectively reduces costs; during the elevator installation stage or when the communication device is abnormal, the pit can still control the shaft lighting. During the elevator installation process, there is no need to wait for the communication device to be fully debugged and normal before operating the pit lighting, which is convenient for construction personnel; when the communication device fails, maintenance personnel can directly control the lighting through the pit operation unit in the pit, which improves the convenience and efficiency of engineering installation and maintenance.

[0021] As a further improvement of the technical solution of the present invention, when the power supply unit of the elevator control system is normally powered, the machine room communication device and the pit communication device are both powered by the elevator control system, the machine room communication detection drive component and the pit communication detection drive component are energized and activated at the same time, so that the machine room communication detection execution component and the pit communication detection drive component are activated at the same time, the machine room forward action mechanism and the pit forward action mechanism are closed at the same time, the machine room reverse action mechanism and the pit reverse action mechanism are disconnected at the same time, the channel of the pit communication device is connected, the loop of the pit operation unit is disconnected, the personnel operate the communication operation unit to activate, and transmit the signal to the elevator control system through the communication channel. After the elevator control system performs logical operation processing, the control unit drives the drive component to activate, the control unit executes the component to activate, and the lighting unit is lit or extinguished.

[0022] As a further improvement of the technical solution of the present invention, when the power supply unit of the elevator control system is powered off, the machine room communication device and the pit communication device both lose power, and the machine room communication detection drive component and the pit communication detection drive component lose power and disconnect at the same time, so that the machine room communication detection execution component and the pit communication detection drive component act at the same time, the machine room forward action mechanism and the pit forward action mechanism are disconnected at the same time, the machine room reverse action mechanism and the pit reverse action mechanism are closed at the same time, the channel of the pit communication device is disconnected, the loop of the pit operation unit is connected, the personnel operate the pit operation unit to act, and the lighting unit is lit or extinguished.

[0044] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0045] See also Figures 1 to 5 The present invention provides a technical solution: a shaft lighting system based on communication channel control, comprising:

[0046] Elevator control system, used to process communication signals and output control signals;

[0047] An elevator control system power supply unit, connected to the elevator control system and supplying power to it;

[0048] A lighting unit is arranged in the elevator shaft to provide lighting;

[0049] A shaft lighting power supply unit, providing power to the lighting unit;

[0050] A power supply, used to separate two circuits to supply power to the elevator control system power supply unit and the shaft lighting power supply unit respectively;

[0051] A machine room operation unit, arranged in the machine room, for operating the lighting unit;

[0052] Computer room communication device, used for communication on the computer room side;

[0053] a machine room communication detection unit, electrically connected to the elevator control system via the machine room communication device;

[0054] A pit communication device for communicating on the pit side;

[0057] A pit operation unit, arranged in the pit, for controlling the lighting unit and having a control circuit multiplexed with a communication channel of the pit communication device, the two being mutually exclusive and reversely self-locking;

[0058] A control unit, through which the elevator control system is electrically connected to the lighting unit.

[0059] The present invention constructs an overall architecture of a shaft lighting system based on communication channel control. Through the coordinated work of various components, multi-position and multi-mode control of the elevator shaft lighting is realized, which solves the problems of inconvenient control and low intelligence of traditional lighting systems, improves the flexibility and reliability of elevator shaft lighting control, ensures the effective operation of elevator shaft lighting under different working conditions, and provides basic support for the safety and convenience of the overall operation of the elevator.

[0060] Specifically, in the present embodiment, the machine room communication detection unit includes a machine room communication detection drive component and a machine room communication detection execution component, and the machine room communication detection execution component includes a machine room forward action mechanism and a machine room reverse action mechanism; the machine room forward action mechanism and the machine room reverse action mechanism act simultaneously. It should be noted that the specific structural design of the machine room communication detection unit can accurately monitor the connection status between the machine room communication device and the elevator control system and the transmission of the communication signal. Through the coordinated action of the machine room forward action mechanism and the machine room reverse action mechanism, the on and off of the machine room communication related circuits are adjusted in time to ensure the stability and reliability of the communication, avoid the failure of the shaft lighting control due to communication failure, and improve the overall robustness and fault tolerance of the system.

[0061] Specifically, in the present embodiment, the pit communication detection unit includes a pit communication detection drive component and a pit communication detection execution component, and the pit communication detection execution component includes a pit forward action mechanism and a pit reverse action mechanism; the pit forward action mechanism and the pit reverse action mechanism act simultaneously. It should be noted that the specific structural design of the pit communication detection unit enables it to play the same key role on the pit side. In the pit environment, the communication link between the pit communication device and the elevator control system is effectively monitored, and the simultaneous action of the pit forward action mechanism and the pit reverse action mechanism is utilized to reasonably switch the working mode of the pit operation unit and the communication channel according to the communication status, ensuring that the shaft lighting can be reliably controlled regardless of whether the communication in the pit is normal or abnormal, which greatly facilitates the maintenance and inspection of the elevator pit and improves the efficiency and safety of engineering operations.

[0062] Specifically, in the present embodiment, when the power supply unit of the elevator control system is normally powered, the machine room communication device and the pit communication device are both powered by the elevator control system, the machine room communication detection drive component and the pit communication detection drive component are powered at the same time, so that the machine room communication detection execution component and the pit communication detection drive component are simultaneously activated, the machine room forward action mechanism and the pit forward action mechanism are simultaneously closed, the machine room reverse action mechanism and the pit reverse action mechanism are simultaneously disconnected, the channel of the pit communication device is connected, the loop of the pit operation unit is disconnected, the personnel operate the communication operation unit to operate, and the signal is transmitted to the elevator control system through the communication channel. After the elevator control system performs logical operation processing, the control unit drives the drive component to operate, the control unit executes the component to operate, and the lighting unit is lit or extinguished. It should be noted that in the conventional operation scenario where the power supply unit of the elevator control system is normally powered, the workflow of the present invention ensures the intelligence and convenience of the shaft lighting control. Through the coordination of the actions of the machine room and the pit communication detection components, the communication channel is preferentially used for lighting control, and personnel can flexibly remotely control the lighting unit at different locations with the help of the communication operation unit. This method reduces the reliance on traditional cable connection control, integrates resources, improves system response speed and control accuracy, facilitates intelligent management and monitoring of elevators, and reduces costs and failure risks caused by laying a large number of cables.

[0063] Specifically, in the present embodiment, when the power supply unit of the elevator control system is powered off, the machine room communication device and the pit communication device are both powered off, the machine room communication detection drive component and the pit communication detection drive component are powered off and disconnected at the same time, so that the machine room communication detection execution component and the pit communication detection drive component are simultaneously actuated, the machine room forward action mechanism and the pit forward action mechanism are simultaneously disconnected, the machine room reverse action mechanism and the pit reverse action mechanism are simultaneously closed, the channel of the pit communication device is disconnected, the loop of the pit operation unit is connected, the personnel operate the pit operation unit to operate, and the lighting unit is lit or extinguished. It should be noted that when the special situation of the power supply unit of the elevator control system being powered off occurs, the mechanism of the present invention can automatically switch the control mode of the pit operation unit. The loop of the pit operation unit is connected in time, so that the pit staff can directly operate the pit operation unit to realize the control of the shaft lighting without relying on the normal operation of the elevator control system power supply and communication device. This effectively solves the problem of the pit lighting being unable to be controlled when the elevator loses power or the system fails, ensuring that pit maintenance and emergency response work can be carried out smoothly under lighting conditions, and improving the overall emergency response capabilities and safety of the elevator.

[0064] Specifically, in the present embodiment, the communication operation unit, the machine room operation unit and the pit operation unit are all 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 various types of communication operation units, machine room operation units and pit operation units greatly enrich the way users interact with the shaft lighting system. Whether it is traditional button and switch operation, or advanced pulse, waveform, voice recognition, sensing, touch, QR code scanning and other methods, they can meet the operating habits and needs of different users in different scenarios. This not only improves the user experience, but also provides a broad space for the expansion of intelligent elevator control, so that shaft lighting control can be better integrated into the overall ecosystem of modern intelligent buildings, and promote the intelligent development and innovative application of elevator technology.

[0065] Specifically, in the present embodiment, the machine room communication device and the pit communication device are one or more of a five-party intercom device, a calling device, an elevator status detection device or an elevator master control device. It should be noted that the selection of diversified machine room communication devices and pit communication devices enables the system to be flexibly adapted according to the specific configuration, functional requirements and overall communication architecture of the elevator. Whether it is to use a five-party intercom device to realize lighting control communication in an emergency, or to use a calling device, an elevator status detection device or an elevator master control device to transmit lighting control signals for daily or specific functions, it can ensure close cooperation and information sharing between the shaft lighting control and other functional modules of the elevator. This improves the compatibility and scalability of the system, reduces the difficulty and cost of system integration caused by the limitations of the communication device selection, and is conducive to the optimization and improvement of the overall performance of the elevator system. It should be noted that a variety of types of control units are available, which can be adapted according to the scale, complexity and cost budget of different elevator projects. Control units such as I / O ports, transistors, thyristors or specially designed control circuits, control devices, etc., while meeting the precise control of the lighting unit, each has different performance characteristics and cost advantages. This enables the system to strike a balance between control performance and cost during design and implementation, ensuring that while achieving efficient and stable lighting control, the overall construction and maintenance costs of the system are reduced, thereby improving the market competitiveness and applicability of the product.

[0066] Specifically, in this 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.

[0067] Specifically, in the present embodiment, the communication channel includes one or more of the five-party intercom device communication channel, the calling device communication channel, the elevator status detection device communication channel, and the elevator master control device communication channel, and any group of communication channels can be used for the control of the shaft lighting, and multiple groups of channels can be used together for the control of the shaft lighting. It should be noted that the application of multiple types of communication channels provides redundant and flexible communication paths for shaft lighting control. Whether it is the five-party intercom device communication channel, the calling device communication channel, the elevator status detection device communication channel or the elevator master control device communication channel, they can all undertake the task of transmitting lighting control signals individually or in combination. This enhances the reliability of system communication. When a communication channel fails, other channels can take over the work in time to ensure that the shaft lighting control is not affected. At the same time, the use of multiple channels is also conducive to the performance optimization and resource allocation of the system under different functional requirements and communication loads, and improves the communication efficiency and stability of the entire elevator system.

[0068] Specifically, in the present embodiment, the elevator control system power supply unit does not affect the control of the machine room operation unit regardless of whether it is powered off or powered normally. It should be noted that the independence of the control of the machine room operation unit is ensured, and the machine room personnel can directly control the shaft lighting at any time regardless of how the power supply status of the elevator control system power supply unit changes. This is particularly important in some special scenarios, such as when the shaft lighting near the machine room needs to be controlled separately during elevator maintenance, or when there is a local failure in the elevator control system but the machine room still needs lighting protection. The autonomy and flexibility of the machine room operation are improved, the risk of failure of the machine room lighting control due to failure of the overall elevator system is reduced, and the safety and maintainability of the elevator system are further improved.

[0069] Specifically, the specific working principle of the present invention is:

[0070] 1. When power supply and communication are normal

[0071] Initial state:

[0072] The power supply provides power for the entire system. One of the circuits is supplied to the elevator control system power supply unit, which provides power for the normal operation of the elevator control system. Another circuit is supplied to the shaft lighting power supply unit, which provides basic power support for the shaft lighting system. However, whether the lighting is on depends on the control signal.

[0073] The normal power supply of the elevator control system power supply unit enables the machine room communication device to be powered, and then the machine room communication detection drive component and the pit communication detection drive component are powered and activated at the same time.

[0074] Under the action of the driving assembly, the forward action mechanism of the room communication detection actuator is closed and the reverse action mechanism is disconnected; the forward action mechanism of the pit communication detection actuator is also closed and the reverse action mechanism is disconnected. This action connects the communication device and channel, while the pit operation unit and circuit are in a disconnected and invalid state.

[0075] Lighting control process:

[0076] When a person operates in a machine room or other location where a communication operation unit can be operated (such as through an operation panel of a five-party intercom device, etc.), the operation unit generates a control signal.

[0077] The signal is sent to the elevator control system via a communication terminal (such as a signal transceiver module of a corresponding communication device).

[0078] After receiving the signal, the elevator control system processes the signal according to the preset logic operation program and analyzes whether the signal corresponds to an instruction such as turning on or off the shaft lighting.

[0079] After the processing is completed, the elevator control system outputs a control signal to drive the control unit. The control unit drives its driving component to act according to the received signal, and then the control unit executes the component action, and finally realizes the lighting unit to light up or turn off. For example, if it is a lighting instruction, the control unit execution component will close the circuit, so that the current passes through the lighting unit, thereby realizing lighting.

[0080] 2. When the power supply unit of the elevator control system is powered off

[0081] State switching:

[0082] Once the elevator control system power supply unit is powered off, the communication device loses power supply.

[0083] The computer room communication detection drive component and the pit communication detection drive component lose power and are disconnected at the same time.

[0084] At this time, the forward action mechanism of the communication detection actuator in the machine room is disconnected, and the reverse action mechanism is closed; the forward action mechanism of the communication detection actuator in the pit is disconnected, and the reverse action mechanism is closed. This causes the communication device and channel to be disconnected, while the pit operation unit and loop are connected.

[0085] Manual pit control:

[0086] When in this state, personnel operate the pit operating unit (such as a rocker switch of the pit) in the pit.

[0087] The action of the pit operating unit directly controls the on-off of the lighting circuit, thereby turning the lighting unit on or off. For example, when the pit operating unit is operated to close the circuit, current will flow to the lighting unit, and the shaft light will light up, providing lighting for maintenance or repair work in the pit.

[0088] 3. Independence of the computer room operation unit

[0089] During the whole process, no matter whether the elevator control system power supply unit is powered off or powered normally, the machine room operation unit can independently control the shaft lighting. This is because its control circuit is relatively independent of the control logic of the pit operation unit and the communication device. When the machine room personnel need to operate the lighting, they can directly perform the corresponding lighting or extinguishing operation through the machine room operation unit without excessive interference from the power supply or communication status of other parts, ensuring the effective control ability of the machine room over the shaft lighting under different circumstances.

[0090] Through the above-mentioned work processes under different power supply and communication conditions, the shaft lighting system can flexibly and reliably realize multi-location (machine room, pit, etc.) and multi-mode (communication control and local operation unit control) control of elevator shaft lighting, meeting the needs of elevator shaft lighting in various scenarios, and has obvious advantages in cost control and system integration.

[0091] Specifically, in actual application scenarios, the power supply serves as the power source for the entire shaft lighting system controlled based on the communication channel. Its two independent outputs accurately provide stable power to the elevator control system power supply unit and the shaft lighting power supply unit, laying a solid foundation for the normal operation of the system.

[0092] In the initial stage of elevator installation, the pit operation unit plays a key role because the communication system is often not fully built or is in an abnormal state of unstable debugging. If the pit workers need to turn on the shaft lighting to assist in construction, they only need to conveniently operate the pit operation unit. Thanks to the unique multiplexing design of the pit operation unit control circuit and the communication channel of the communication device, as well as the mutual exclusion and reverse self-locking mechanism between the two, in this case, the pit operation unit and the circuit are automatically connected, and the current flows smoothly to the lighting unit, quickly realizing the lighting of the shaft lighting, which greatly facilitates the elevator installation and construction process, improves work efficiency and ensures construction safety.

[0093] When the elevator enters the stage of normal operation and the communication function is normal, the control method of the shaft lighting becomes more diverse and intelligent. Assuming that the operator is in the machine room, if a button-type operating unit is used, when the corresponding lighting control button is pressed, the operation signal will immediately pass through the communication terminal connected to it (such as the signal transmission module in the machine room communication device) and transmit the signal to the elevator control system at an efficient communication rate. With its powerful signal processing capabilities and preset logical operation programs, the elevator control system accurately analyzes and judges the received signals, and then outputs the adapted control signal to drive the control unit. After the control unit receives the instruction, its internal drive component quickly acts, thereby driving the execution component to accurately control the on and off of the lighting circuit, and finally realizes the lighting or extinguishing of the lighting unit. The whole process responds quickly and is stable and reliable.

[0094] If the operator chooses the novel operation mode of voice control, a clear voice command such as "turn on the shaft lighting" or "turn off the shaft lighting" is issued through the voice recognition device. The voice recognition device quickly converts the voice signal into an electrical signal and transmits it to the elevator control system through the communication channel. The elevator control system intelligently recognizes and processes the voice command, and the subsequent control process is similar to the button operation, which can also accurately realize the control of the lighting unit, fully demonstrating the advantages and charm of the intelligent control of the present invention.

[0095] In the scene outside the hall, when passengers find that the elevator shaft lighting needs to be adjusted, if the calling device is used as a communication device and integrated with the lighting control function, the passengers can find the corresponding lighting control function key on the calling device operation panel to operate. The operation signal will be quickly transmitted to the elevator control system along the communication channel to which the calling device belongs. The elevator control system processes it according to the established control logic, thereby realizing remote control of the shaft lighting, further improving the user experience and the convenience of the elevator system.

[0096] During the operation of the entire system, the machine room communication detection unit and the pit communication detection unit are like loyal guards, always monitoring the working status of the communication device and the communication channel. For example, when the power supply status of the elevator control system power supply unit fluctuates, such as when the normal power supply switches to a power-off state, the machine room communication detection drive component and the pit communication detection drive component will be disconnected synchronously. This change triggers the machine room communication detection execution component and the pit communication detection execution component to act simultaneously, with their forward mechanisms disconnected and their reverse mechanisms closed, causing the communication device and channel to be disconnected, and the pit operation unit and the loop to be connected, achieving seamless switching of the control status, ensuring that the shaft lighting can be effectively controlled under various circumstances, and also reflecting the high reliability and stability of the system.

[0097] Whether in the installation and commissioning of the elevator, normal operation or special working conditions, this shaft lighting system based on communication channel control can achieve precise control of shaft lighting flexibly, stably and intelligently with its unique design and advanced technical means, providing all-round and powerful support for the safe operation, efficient maintenance and intelligent development of the elevator.

[0098] In summary, the shaft lighting system based on communication channel control of the present invention effectively overcomes many defects of traditional shaft lighting technology through innovative design and technical means, and has significant advantages in reducing costs, improving the level of intelligent control, facilitating engineering installation and maintenance, and solving various specific design engineering problems. It has high innovation and practicality, and provides strong support and guarantee for the development of elevator shaft lighting technology.

Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
