Description

Technical Field

[0001] The invention relates to the technical field of elevator shaft lighting, in particular to an elevator communication type shaft lighting system. Background Art

[0002] The existing elevator shaft lighting is laid throughout the elevator shaft, which includes 220V power supply, circuit breaker, circuit protection (FUSE), cables / wires, wire ducts, lamps, control switches and other devices. The lighting (light on / off) is controlled by a 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 it is necessary to add serial number ④ cable / wire and ⑦ rocker switch to the existing circuit to realize shaft lighting that "can be controlled in both the elevator machine room and the pit".

[0003] There are many defects in the existing shaft lighting technology. On the one hand, there are many control devices, and cables and switches need to be added when realizing dual control, which directly leads to a significant increase in cost. On the other hand, the power supply line is often too long, and it needs to go from the machine room to the bottom pit and then return to the machine room. Such a long line causes serious voltage loss, resulting in a significant decline in the performance of the shaft lamp. When the shaft is high, in order to reduce the voltage loss, the cross-sectional area of ​​the cable conductor has to be increased, which will undoubtedly greatly increase the cable cost. Furthermore, traditional installation and maintenance are extremely inconvenient, and the cable laying and control devices are scattered everywhere, making the installation and maintenance workload huge and inefficient. In addition, in the face of special needs, such as adding control points in the car, car top, outside the hall, and monitoring room to realize triple control, more cables and control devices are required, the cost will rise sharply, and the voltage loss will also double. Finally, its control method is too single, and it can only be controlled by the rocker switch in the machine room or the bottom pit, which seriously hinders the development of intelligent elevator control. Summary of the invention

[0004] The purpose of the present invention is to provide an efficient, intelligent, low-cost and easy-to-install and maintain elevator communication shaft lighting system, which integrates the operation unit, communication unit and control unit into the existing communication device of the elevator (such as a five-party intercom device, a calling device, etc.), and uses its internal devices to build operation and control functions, reducing the need for additional control devices and reducing hardware procurement costs. The elevator communication device and its cables are used as communication units for signal transmission, which reduces the laying of additional cables required for dual or multi-link control, reducing both the cost of cable materials and the labor cost caused by cable laying. Especially in complex scenarios where the shaft is high or multiple control points are required, the cost reduction effect is more prominent.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: an elevator communication type shaft lighting system, comprising an operating unit, a communication unit, a control unit and a lighting unit, the communication unit is used to transmit the signal generated by the operating unit to the control unit, the control unit controls the lighting and extinguishing states of the lighting unit according to the signal sent by the communication unit, and a connection relationship for signal transmission and processing is formed among the operating unit, the communication unit and the control unit, and a control connection relationship is formed between the control unit and the lighting unit.

[0006] As a further improvement of the technical solution of the present invention, the operating unit, communication unit, and control unit are all integrated inside the five-party intercom device, calling device, elevator status detection device, and elevator master control device of the elevator communication device. The operating unit and the communication unit form a direct signal transmission connection inside the elevator communication device, the communication unit and the control unit form a direct signal transmission connection inside the elevator communication device, and the control unit forms an interactive connection with related devices inside the elevator communication device to achieve linkage or independent operation with the elevator control system.

[0007] As a further improvement of the technical solution of the present invention, the five-party intercom device, calling device, elevator status detection device, and elevator master control device of the elevator communication device can all work independently, and have the ability to establish a data interactive connection with the elevator control system to realize linkage work. When working in linkage, a two-way data transmission connection relationship is formed between the elevator control system and the control unit in the communication device. The elevator control system can send a control command signal to the control unit, and the control unit can feedback the relevant status signal of the shaft lighting system to the elevator control system.

[0008] As a further improvement of the technical solution of the present invention, the internal components of the elevator communication device (such as buttons, input I / O ports, output I / O ports, etc.) are used to construct an operating unit and a control unit. The internal components of the operating unit form a trigger signal connection relationship with the communication unit. When the internal components of the operating unit are triggered, a corresponding signal is generated and transmitted to the communication unit. The internal components of the control unit form a signal connection relationship for receiving and processing with the communication unit. The control unit performs logical operation processing based on the signal transmitted by the communication unit and generates a control signal for controlling the lighting unit, thereby reducing the number of operating components and forming an efficient signal processing connection mechanism.

[0009] As a further improvement of the technical solution of the present invention, an elevator communication device and its cables are used to construct a communication unit, and the communication unit forms a signal transmission channel connection relationship between the elevator communication devices through its cables to perform signal transmission between the operating unit and the control unit, thereby reducing the layout of double or multiple cables. The cables of the communication unit form an adaptive connection relationship with the signal transmission module inside the elevator communication device to ensure stable and efficient signal transmission; after receiving the signal generated by the operating unit, the communication unit transmits it to the control unit; the control unit generates a control signal through logical operation processing, and then transmits the control signal to the lighting unit through the control connection relationship with the lighting unit, thereby realizing the control of the shaft lighting. During the whole process, a close signal and control flow connection relationship is formed between the units.

[0010] As a further improvement of the technical solution of the present invention, the implementation methods of the operating unit include but are not limited to buttons / switch, pulses, waveforms, voice, sound, induction, touch and QR code. Corresponding signal sensing and transmission connection relationships are formed between the operating units of different implementation methods and the communication units respectively. When the operating unit is triggered, it can generate a signal in a specific form according to its own characteristics and transmit it to the communication unit.

[0011] As a further improvement of the technical solution of the present invention, the communication unit adopts wired transmission or wireless transmission, and adopts elevator-specific communication technology to construct a signal transmission connection architecture between it and the operating unit and the control unit. During wired transmission, the cable forms a physical connection relationship with each related interface to ensure signal transmission. During wireless transmission, a wireless signal connection relationship is formed with the operating unit and the control unit through a wireless signal transmitting and receiving module to realize the transmission of the operating unit signal to the control unit.

[0012] As a further improvement of the technical solution of the present invention, the control unit receives the operation unit signal and outputs a control signal to control the lighting and extinguishing of the lighting lamp after performing logic operation processing. The control signal is one of an I / O port, a transistor, a thyristor, or a control circuit or control device constructed for this purpose. An electrical connection relationship is formed between the control unit and the lighting lamp unit through a control line, and the control signal is transmitted to the lighting lamp unit through the connection relationship to drive the change of its working state.

[0013] As a further improvement of the technical solution of the present invention, the power supply circuit of the lighting lamp unit has only two power lines, and the light control signal of the control unit is connected in series to the positive pole of the power supply. A series control connection relationship is formed between the control unit and the power supply circuit. The control unit controls the light control signal to realize the control of the on and off of the power supply of the lighting lamp unit, thereby controlling the lighting and off of the lighting lamp.

[0014] As a further improvement of the technical solution of the present invention, the control process of the elevator communication type shaft lighting system includes:

[0015] Lighting process: After the power is supplied, the switch of the operating unit is turned on, the signal connection between the operating unit and the communication unit is triggered, and the communication unit transmits the switch signal to the control unit. The control unit receives the signal and processes it through logical operations, then outputs the light control signal through the control connection relationship with the lighting unit, so that the lighting unit lights up;

[0016] Lighting off process: the switch of the operating unit is turned off, the signal connection between the operating unit and the communication unit is triggered, the communication unit transmits the switch signal to the control unit, the control unit receives the signal and processes it through logical operation, then outputs the light control signal through the control connection relationship with the lighting unit, so that the lighting unit is turned off;

[0017] Control system linkage lighting process: operate the elevator maintenance button, the maintenance signal is transmitted to the elevator control system through the connection relationship between the communication device and the elevator control system, the elevator control system performs logical operation processing and transmits the signal to the control unit through the connection relationship with the control unit in the communication device, the control unit receives the signal and performs logical operation processing and outputs the light control signal through the control connection relationship with the lighting unit, so that the lighting unit lights up;

[0018] Control system linkage light-off process: When the elevator returns to normal operation, the elevator control system transmits the normal status signal to the control unit through the connection relationship with the control unit in the communication device. After receiving the signal and processing it through logical operations, the control unit outputs the light control signal through the control connection relationship with the lighting unit to turn off the lighting unit.

[0019] The present invention has the following beneficial effects:

[0020] Significantly improved cost-effectiveness:

[0021] By integrating the operating unit, communication unit and control unit inside the existing communication device of the elevator (such as five-party intercom device, calling device, etc.), and using its internal devices to build operation and control functions, the demand for additional control devices is reduced and the hardware procurement cost is reduced.

[0022] The use of elevator communication devices and their cables as communication units for signal transmission reduces the need for additional cable laying for dual or multi-link control, which reduces both the cost of cable materials and the labor cost associated with cable laying. This is especially true in complex scenarios where the shaft is high or multiple control points are required, where the cost reduction effect is more significant.

[0023] Improved convenience of installation and maintenance:

[0024] Since each functional unit is integrated into the elevator communication device, the cable layout is simplified by reusing the communication device cables, so there is no need to deal with a large number of scattered control components and complex cable connections during the installation process, which greatly shortens the installation time and improves the installation efficiency.

[0025] During maintenance, technicians can use the regular inspection channels and tools of the elevator communication device to more conveniently troubleshoot and repair the operation, communication and control units of the shaft lighting system, reducing downtime caused by difficult fault location and inconvenient maintenance, reducing maintenance costs and improving the overall operational reliability of the elevator.

[0026] Improved control flexibility and scalability:

[0027] The various implementation methods of the operating unit (such as buttons / switches, pulses, voice, etc.) provide users with a wealth of control options, which can meet the personalized operation needs of different scenarios and personnel, and improve the user experience and applicability of the system.

[0028] Based on the linkage capability of the elevator communication device and the elevator control system, the shaft lighting can easily realize the intelligent association with the elevator operation status, such as automatically lighting the lighting during maintenance, which not only facilitates maintenance work, but also provides protection for personnel safety. At the same time, this linkage architecture also lays the foundation for further expanding the intelligent functions of elevators in the future, facilitating integration with other elevator intelligent control systems or external monitoring equipment to adapt to the evolving elevator technology needs.

[0029] Performance optimization and stability improvements:

[0030] The lighting unit power circuit has only two power lines and the control unit light control signal is connected in series with the positive pole of the power supply, which simplifies the power line structure, reduces line failure points, and improves the stability and reliability of the power supply.

[0031] The communication unit uses elevator-specific communication technology for signal transmission. Whether wired or wireless, it can ensure the accuracy and timeliness of signal transmission between the operating unit and the control unit, effectively avoiding lighting control errors caused by signal interference or transmission delays, thereby ensuring the stable and efficient operation of the shaft lighting system and improving the overall performance of the shaft lighting.

[0032] Energy saving and environmental protection benefits:

[0033] The precise control unit logic operation processing combined with a variety of operating unit triggering methods can achieve more precise lighting and extinguishing control of the lighting unit, avoiding unnecessary long-term lighting, reducing energy consumption, complying with the development concept of modern energy conservation and environmental protection, and helping to reduce energy consumption costs and environmental impact during elevator operation.

[0047] Specifically, in the present embodiment, the operation unit, communication unit, and control unit are all integrated and arranged inside the five-party intercom device, the calling device, the elevator state detection device, and the elevator master control device of the elevator communication device. The operation unit and the communication unit form a direct signal transmission connection inside the elevator communication device, and the communication unit and the control unit form a direct signal transmission connection inside the elevator communication device, and the control unit forms an interactive connection with the relevant devices inside the elevator communication device to realize linkage or independent work with the elevator control system.

[0048] Specifically, in this embodiment, the five-party intercom device, calling device, elevator status detection device, and elevator master control device of the elevator communication device can all work independently, and have the ability to establish a data interactive connection with the elevator control system to achieve linkage work. When working in linkage, a two-way data transmission connection relationship is formed between the elevator control system and the control unit in the communication device. The elevator control system can send a control command signal to the control unit, and the control unit can feedback the relevant status signal of the shaft lighting system to the elevator control system.

At the same time, this linkage architecture also lays the foundation for further expanding the intelligent functions of elevators in the future, and is convenient for integration with other elevator intelligent control systems or external monitoring equipment to adapt to the ever-evolving elevator technology needs.

[0049] Specifically, in the present embodiment, the internal components of the elevator communication device (such as buttons, input I / O ports, output I / O ports, etc.) are used to construct an operating unit and a control unit. The internal components of the operating unit form a trigger signal connection relationship with the communication unit.

The internal components of the control unit form a signal connection relationship for receiving and processing with the communication unit. The control unit performs logical operations based on the signal transmitted by the communication unit and generates a control signal for controlling the lighting unit, thereby reducing the number of operating components and forming an efficient signal processing connection mechanism.

[0050] Specifically, in this embodiment, the communication unit is constructed by using the elevator communication device and its cable. The communication unit forms a signal transmission channel connection relationship between the elevator communication device through its cable to perform signal transmission between the operating unit and the control unit, reducing the layout of double or multiple cables.

Especially in complex scenarios where the shaft is high or multiple control points are required, the cost reduction effect is more prominent.

[0051] Specifically, in this embodiment, the implementation methods of the operating unit include but are not limited to buttons / switches, pulses, waveforms, voices, sounds, induction, touch and QR codes. The operating units of different implementation methods respectively form corresponding signal induction and transmission connection relationships with the communication unit. When the operating unit is triggered, it can generate a specific form of signal according to its own characteristics and transmit it to the communication unit. It should be noted that the various implementation methods of the operating unit (such as buttons / switches, pulses, voices, etc.) provide users with a wealth of control options, which can meet the personalized operation needs of different scenarios and personnel, and improve the user experience and the applicability of the system.

[0052] Specifically, in the present embodiment, the communication unit adopts wired transmission or wireless transmission, and uses elevator-specific communication technology to construct a signal transmission connection architecture between it and the operating unit and the control unit. In wired transmission, the cable forms a physical connection relationship with each related interface to ensure signal transmission. In wireless transmission, a wireless signal connection relationship is formed with the operating unit and the control unit through a wireless signal transmitting and receiving module to realize the transmission of the operating unit signal to the control unit. It should be noted that the communication unit adopts elevator-specific communication technology for signal transmission. Whether it is wired or wireless, it can ensure the accuracy and timeliness of signal transmission between the operating unit and the control unit, effectively avoiding lighting control errors caused by signal interference or transmission delays, thereby ensuring the stable and efficient operation of the shaft lighting system and improving the overall performance of the shaft lighting.

[0053] Specifically, in this embodiment, the control unit receives the signal from the operating unit and outputs a control signal to control the lighting and extinguishing of the lighting lamp after performing logic operation processing. The control signal is one of an I / O port, a transistor, a thyristor, or a control circuit or control device constructed for this purpose. The control unit and the lighting lamp unit are electrically connected through a control line, and the control signal is transmitted to the lighting lamp unit through the connection relationship to drive the change of its working state.

[0054] Specifically, in this embodiment, the power supply circuit of the lighting lamp unit has only two power lines, and the control signal of the control unit is connected in series to the positive pole of the power supply. A series control connection relationship is formed between the control unit and the power supply circuit, and the control unit controls the control signal to realize the control of the power supply of the lighting lamp unit, thereby controlling the lighting and extinguishing of the lighting lamp. It should be noted that the design that the power supply circuit of the lighting lamp unit has only two power lines and the control signal of the control unit is connected in series to the positive pole of the power supply simplifies the power supply line structure, reduces line fault points, and improves the stability and reliability of the power supply.

[0055] Specifically, in this embodiment, the control process of the elevator communication type shaft lighting system includes:

[0056] Lighting process: After the power is supplied, the switch of the operating unit is turned on, the signal connection between the operating unit and the communication unit is triggered, and the communication unit transmits the switch signal to the control unit. The control unit receives the signal and processes it through logical operations, then outputs the light control signal through the control connection relationship with the lighting unit, so that the lighting unit lights up;

[0057] Lighting off process: the switch of the operating unit is turned off, the signal connection between the operating unit and the communication unit is triggered, the communication unit transmits the switch signal to the control unit, the control unit receives the signal and processes it through logical operation, then outputs the light control signal through the control connection relationship with the lighting unit, so that the lighting unit is turned off;

[0058] Control system linkage lighting process: operate the elevator maintenance button, the maintenance signal is transmitted to the elevator control system through the connection relationship between the communication device and the elevator control system, the elevator control system performs logical operation processing and transmits the signal to the control unit through the connection relationship with the control unit in the communication device, the control unit receives the signal and performs logical operation processing and outputs the light control signal through the control connection relationship with the lighting unit, so that the lighting unit lights up;

[0059] Control system linkage light-off process: When the elevator returns to normal operation, the elevator control system transmits the normal status signal to the control unit through the connection relationship with the control unit in the communication device. After receiving the signal and processing it through logical operations, the control unit outputs the light control signal through the control connection relationship with the lighting unit to turn off the lighting unit.

[0060] Specifically, in actual application scenarios, the elevator communication shaft lighting system demonstrates excellent performance and convenience.

[0061] In the machine room, when maintenance personnel need to operate the shaft lighting, they can directly use the operating unit integrated in the elevator master control device in the machine room, such as pressing a special button (a form of operating unit) set on its panel. This operation instantly triggers the signal connection between the operating unit and the communication unit, and the switch ON signal generated by the button is quickly transmitted to the control unit through the communication unit (with the help of the signal transmission line and related communication module inside the master control device). After receiving the signal, the control unit processes it according to its built-in logical operation rules and then generates a corresponding light control signal. Since the control unit and the lighting unit are electrically connected through a specific control line, the light control signal can be accurately transmitted to the lighting unit, thereby prompting the lighting unit in the shaft to be successfully lit, providing sufficient lighting for related operations from the machine room to the shaft.

[0062] In the pit area, if there are staff members performing maintenance work, they can control the lighting through the operating unit contained in the pit calling device. For example, the operation is triggered by a voice command (the voice form of the operating unit). The voice recognition module (part of the operating unit) generates a corresponding signal after recognizing the voice command, and the signal is transmitted to the control unit via the communication unit inside the calling device (using its built-in voice signal transmission line and communication chip and other components). After the control unit analyzes and processes the voice signal, it outputs a light control signal to light up the lighting unit, ensuring that the pit working environment is bright and safe.

[0063] The shaft lighting can also be conveniently controlled in places such as outside the hall, inside the car, on the car roof, and in the monitoring center. Taking the outside of the hall as an example, passengers or staff can operate through the touch operation unit (such as a touch sensing panel) on the outside hall call device. When a finger touches the panel to trigger a specific touch command, the operation unit generates a touch signal, which is transmitted to the control unit along the communication cable between the call device and other elevator communication devices (the wired transmission part of the communication unit). After calculation, the control unit outputs a light control signal to realize the lighting or extinguishing control of the lighting unit.

[0064] When the elevator is in maintenance status, the operator presses the elevator maintenance button, and the maintenance signal is first transmitted to the elevator control system through the elevator's communication line. After the elevator control system processes according to the preset logic, it transmits the relevant signal to the control unit through the linkage connection relationship with the control unit in each communication device. After receiving the signal, the control unit performs logical operation processing again, and finally outputs the light control signal to light up the lighting unit, providing all-round lighting guarantee for the maintenance personnel working in the shaft, effectively improving the safety and convenience of maintenance operations. When the maintenance is completed, the elevator is operated to resume normal operation, and the elevator control system generates a normal status signal and transmits it to the control unit. The control unit outputs the light control signal after logical operation processing to turn off the lighting unit, realizing the intelligent linkage between lighting and elevator operation status.

[0065] Regardless of the triggering form of the operating unit, the communication unit can accurately transmit the operating signal between the elevator communication devices with its efficient and stable transmission mechanism, ensuring that the control unit receives the signal in time and generates the correct light control signal, thereby achieving accurate and reliable control of the lighting unit. This shaft lighting system based on the elevator communication device effectively overcomes many drawbacks of traditional shaft lighting technology through the close cooperative connection relationship and interaction mechanism between the units, and provides an intelligent, efficient and low-cost solution for elevator shaft lighting, greatly improving the safety, comfort and energy saving of the overall operation of the elevator.

The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention.
