Description

Technical Field

[0001] The present invention relates to the technical field of elevator guiding devices, and in particular to an intelligent elevator passenger flow guiding device based on multi-source information fusion. Background Art

[0002] In modern commercial complexes, the scale of shopping malls is becoming increasingly large. As the main vertical transportation facility, the efficient guidance of passenger flow is crucial. Traditional elevator passenger flow guidance devices have exposed many problems in actual use, which seriously affect the operating efficiency of shopping malls and customers' shopping experience. Traditional elevator passenger flow guidance often relies on simple signs and manual guidance. Signs are usually fixed in specific locations, and information is not updated in a timely manner, making it difficult to reflect the passenger flow of each elevator room in real time. For example, during the peak hours of shopping malls, some elevator rooms may be crowded due to their proximity to popular stores or promotional areas, while other elevator rooms are relatively idle. However, the signs cannot dynamically convey this information to customers, resulting in customers still queuing in front of popular elevators, causing unnecessary waiting time and greatly reducing the efficiency of passenger flow guidance. From the perspective of pedestrian visual perception, traditional guidance methods lack innovation and appeal. Simple text signs are not very useful in complex shopping mall environments. In addition, it is difficult for traditional devices to directly guide passenger flow to an idle elevator room through visual guidance, resulting in the gathering of pedestrians in the corridors of the shopping mall. When there are too many people in a certain elevator room, there is a lack of effective means to quickly and intuitively guide the crowd to other idle elevator rooms. Customers often need to search in the shopping mall by themselves or ask staff, which not only increases the troubles of customers, but also increases the burden on shopping mall staff. Moreover, since it is impossible to timely and accurately understand the real-time passenger flow status of each elevator room, customers are very blind when choosing elevators, which further aggravates the imbalance of elevator use and reduces the operating efficiency of the entire shopping mall. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides an intelligent elevator passenger flow guiding device based on multi-source information fusion, which solves the problems of low passenger flow guidance efficiency, poor pedestrian visual perception and difficulty in directly guiding passenger flow to an idle elevator room through visual guidance in traditional elevator passenger flow guiding devices.

[0004] To achieve the above-mentioned object, the present invention provides an intelligent elevator passenger flow guiding device based on multi-source information fusion, comprising a coordinating module for calculating and counting the elevator passenger flow of a shopping mall, a ground guiding module for communicating with the coordinating module to guide the passenger flow of the shopping mall to an idle elevator room, a wall indication module for being installed on the wall of the shopping mall elevator room for visual guidance, and a display module for being suspended on the ceiling of the shopping mall for visual guidance; The overall planning module includes a calculation module for calculating the passenger flow of each elevator room in the shopping mall to generate passenger flow data, an analysis module for analyzing the passenger flow data, a signal transceiver module for signal transmission and reception, and a control module for issuing an opening and closing signal. The signal transceiver module is respectively connected to the calculation module and the analysis module for communication to transmit the passenger flow data to the analysis module, the analysis module is connected to the signal transceiver module for communication to receive the passenger flow data for analysis and transmit the opening and closing signal to the control module according to the analysis result, and the control module is respectively connected to the wall guidance module, the wall indication module and the calculation and analysis module for communication to control the wall indication module and the ground guidance module to perform opening and closing operations according to the opening and closing signals; The ground guidance module includes a laying module for laying on the mall corridor, a light display module for displaying light of different colors, and an opening and closing module. The light display module cooperates with the laying module to make the laying module transmit light of the current color to achieve passenger flow guidance. The opening and closing module is connected to the control module in communication to receive the opening and closing signal to control the color change of the light display module. The wall indication module includes a plurality of mounting plates for being respectively mounted on the walls of different elevator rooms in the shopping mall and a driving module for controlling the mounting plates to perform flipping operations. The driving module is communicatively connected with the control module to receive the opening and closing signals to control the mounting plates to perform flipping movements. The front wall and the rear wall of the mounting plate are coated with guide characters. The display module comprises a plurality of display modules for being respectively suspended at different ceiling positions of a shopping mall and a transmission module for being communicated with a calculation module to display passenger flow data on the display module.

[0005] The advantages of adopting the above technical solution are as follows: the initial operation process of adopting the above technical solution is as follows: the calculation module in the overall planning module starts to work, and the passenger flow of each elevator room in the shopping mall is calculated in real time (the information of personnel entry and exit can be collected through the sensors provided by the elevators, etc.), so as to generate accurate passenger flow data, such as the number of people entering and leaving each elevator room per unit time, etc. The generated passenger flow data is transmitted to the analysis module through the signal transceiver module, and the analysis module uses the data analysis algorithm to conduct in-depth analysis of the passenger flow data (for example, analyze the passenger flow change trend of each elevator room, compare the passenger flow differences of elevator rooms at different time periods and on different floors, and judge which elevator rooms are busy and which are relatively idle. Based on these analyses, As a result, the analysis module transmits the corresponding opening and closing signals to the control module). After the control module receives the opening and closing signals, if the passenger flow in a certain elevator room is too large, the control module sends instructions to the opening and closing module in the ground guidance module. The opening and closing module controls the light display module according to the instructions, so that the laying module laid on the mall corridor transmits light of a specific color (such as displaying the path to the idle elevator room as green light to guide the flow of people). The light display module cooperates with the laying module to flexibly change the color of the light according to the instructions to achieve dynamic passenger flow guidance. At the same time, the control module also sends opening and closing signals to the drive module in the wall indication module. For elevator rooms with large passenger flow, the drive module controls the mounting plate to flip after receiving the signal. Since the front and rear walls of the mounting plate are coated with guiding fonts, when it is flipped, the guiding fonts on the rear wall will be displayed, thereby providing visual guidance to pedestrians; at the same time, the transmission module is communicated with the calculation module, and the passenger flow data generated by the calculation module is transmitted in real time to the display module hung at different ceiling positions of the shopping mall. The display module displays the passenger flow of each elevator room to pedestrians in the form of intuitive numbers, charts, etc., so that pedestrians can clearly understand the passenger flow situation of each elevator room from a long distance, and thus choose to go to an idle elevator room on their own.

[0006] Through the above simple operation process, by real-time calculation and analysis of the passenger flow of each elevator room, the passenger flow can be timely and accurately guided to the idle elevator room. For example, during the peak period of the shopping mall, the crowd originally concentrated in front of the popular elevator can be quickly dispersed to other relatively idle elevator rooms, which greatly reduces the waiting time of customers and improves the personnel flow efficiency of the entire shopping mall. Compared with the traditional method, it can transport more passengers per unit time, thus improving the efficiency of elevator use. At the same time, the display module of the ground guidance module cooperates with the laying module to present different colors of light, forming a striking guidance path on the mall corridor, which can attract more attention of pedestrians than traditional signboards. The flip design of the mounting plate of the wall indication module and the intuitive data display of the display module provide pedestrians with diversified and novel visual guidance methods, so that pedestrians can find suitable elevators in the mall more easily and pleasantly, improving the movement experience of pedestrians in the mall. Through the light guidance of the ground guidance module, the guidance font of the wall indication module and the passenger flow display of the display module, they cooperate with each other to form a comprehensive visual guidance system. Whether pedestrians are walking on the ground of the mall, near the elevator room, or at a long distance, they can clearly understand the passenger flow of each elevator room through different visual guidance methods and be directly guided to the vacant elevator room. Through precise visual guidance methods, the problem that traditional devices are difficult to directly guide passenger flow to vacant elevator rooms is effectively solved, thus improving the operation and management level of the mall.

[0007] The present invention is further configured as follows: the calculation module includes a weight measuring structure for installation in a shopping mall elevator and a number measuring structure for installation at the entrance and exit of a shopping mall elevator room; the signal transceiver module includes a wireless communication module; the wireless communication module is communicatively connected with the number measuring structure and the weight measuring structure to receive and transmit elevator room passenger flow data sent by the number measuring structure and elevator passenger flow weight data sent by the weight measuring structure; the analysis module includes an industrial control unit and a server; the industrial control unit is communicatively connected with the wireless communication module to receive elevator room passenger flow data and elevator passenger flow weight data; the industrial control unit pre-stores comparison data; The comparison data includes standard elevator room passenger flow threshold data and standard elevator passenger flow threshold data. The industrial control unit analyzes the elevator room passenger flow data and the elevator passenger flow weight data and compares them with the comparison data and generates a start and close signal according to the comparison result. The server is communicatively connected with the industrial control unit to transmit and store the elevator room passenger flow data and the elevator passenger flow weight data. The control module includes a programmable logic controller, and the programmable logic controller is respectively communicatively connected with the ground guidance module and the wall indication module to control the ground guidance module and the wall indication module to perform start and close operations according to the start and close signal.

[0008] The benefits of adopting the above technical solution are: the calculation module in the above technology integrates the weight measuring structure installed in the shopping mall elevator and the number measuring structure at the entrance and exit of the elevator room. The number measuring structure uses the infrared sensor array to accurately capture the number of people entering and exiting the elevator room and generate detailed elevator room passenger flow data. The weight measuring structure uses the strain gauge pressure sensor to accurately measure the weight of the passengers in the elevator and output the elevator passenger flow weight data. The data is efficiently transmitted to the subsequent modules through the wireless communication module, providing the system with rich and comprehensive original information. Compared with the single data collection method, the integrity and accuracy of the data are greatly improved, laying a solid foundation for subsequent analysis and decision-making; after the industrial control unit in the analysis module receives the elevator room passenger flow data and the elevator passenger flow weight data, it conducts in-depth comparison and analysis with the pre-stored comparison data (including standard elevator room passenger flow threshold data and standard elevator passenger flow threshold data), and accurately judges the passenger flow conditions of each elevator room through scientific algorithms, such as whether it exceeds the load standard, the difference from the normal passenger flow level, etc., and then generates reasonable opening and closing signals; the programmable logic controller of the control module in the above technology According to the opening and closing signals generated by the industrial control unit, the working status of the ground guidance module and the wall indication module is accurately controlled. When the passenger flow in a certain elevator room is too large or overweight, the programmable logic controller responds quickly, and changes the light indication through the display module of the ground guidance module to guide pedestrians to the vacant elevator room; at the same time, the mounting plate of the wall indication module is controlled to flip to display the corresponding guidance information. The precise control mechanism can guide the passenger flow to a reasonable position in a timely and effective manner, significantly improving the efficiency and accuracy of passenger flow guidance and optimizing the operation order of the vertical transportation of the shopping mall; and the server is connected to the industrial control unit for communication, and undertakes the important task of transmitting and storing the passenger flow data of the elevator room and the weight data of the elevator passenger flow. On the one hand, the real-time transmission of data ensures that the industrial control unit can obtain the latest information at any time for analysis and decision-making; on the other hand, long-term and stable data storage provides historical data reference for the operation and management of the shopping mall, which is convenient for trend analysis and strategy adjustment. The whole system architecture is reasonably designed, and the modules work together, which greatly enhances the stability and reliability of the system operation and reduces system failures caused by data loss or transmission interruption. The above technology improves the efficiency of elevator use and reduces the waiting time of passengers through accurate passenger flow guidance, which indirectly improves the operating efficiency of shopping malls. At the same time, each module of the system adopts common and mature equipment and technologies, such as wireless communication modules, programmable logic controllers, etc. These devices are widely available in the market and reasonably priced, which reduces the cost of equipment procurement. In addition, stable and reliable system operation reduces maintenance costs and losses caused by failures. Overall, it has significant cost-effectiveness advantages and is conducive to large-scale promotion and application in shopping malls and other places. The industrial control units, servers and other intelligent devices in the above technology are all existing devices in the prior art, so their structure and functions will not be described in detail.

[0009] The present invention is further provided that: the weighing structure includes a weighing plate for installation at the bottom of the elevator car and a weighing device group for installation between the weighing plate and the elevator car, the weighing device group includes a first data acquisition module and a plurality of strain type pressure sensors, the plurality of strain type pressure sensors are distributed on the surface of the weighing plate, the plurality of strain type pressure sensors are communicatively connected with the first data acquisition module to transmit the weight difference data detected by the strain type pressure sensor to the first data acquisition module for analysis and to generate elevator passenger flow weight data according to the results, the first data acquisition module is communicatively connected with the wireless communication module to transmit the elevator passenger flow weight data to the industrial control unit.

[0010] The benefits of adopting the above technical solution are: in the above technology, a weighing plate is installed at the bottom of the elevator car, and a weighing device group including multiple strain gauge pressure sensors is set between the weighing plate and the elevator car, so that the weight of the passengers in the elevator can be accurately measured. The multiple strain gauge pressure sensors are evenly distributed on the surface of the weighing plate, ensuring a comprehensive perception of the weight changes at various positions in the car, and transmitting the detected slight weight difference data to the first data acquisition module, which generates extremely accurate elevator passenger flow weight data. Compared with the traditional single weighing method, this weighing structure greatly improves the accuracy of the data, and provides a solid and reliable data foundation for subsequent passenger flow analysis and elevator operation decisions; in the above technology, the first data acquisition module transmits the generated elevator passenger flow weight data through the wireless communication module The data is transmitted to the industrial control unit, so that the mall managers can obtain the weight information in the elevator in real time. Combined with other passenger flow data, such as passenger flow and passenger flow distribution in different time periods, the mall can have a more comprehensive understanding of the use of the elevator. For example, during the mall promotion activities, by analyzing the elevator passenger flow weight data, the elevator maintenance time can be reasonably arranged, the elevator operation strategy can be optimized, the elevator utilization efficiency can be improved, and customers can be provided with a better service experience, thereby improving the overall operation and management level of the mall; accurate elevator passenger flow weight data is crucial for the safe and stable operation of the elevator. When the weight of the passengers in the elevator is close to or exceeds the rated load, the elevator control system can respond in time based on the data obtained by the weight measurement structure, such as issuing an overweight alarm to prevent the elevator from causing safety accidents due to overload operation. At the same time, continuous monitoring of the elevator passenger flow weight data helps maintenance personnel to promptly discover abnormal load conditions during the operation of the elevator, perform maintenance and repairs on the elevator in advance, extend the service life of the elevator, and ensure the safety and stability of the elevator in the daily high-intensity operation environment of the mall. The strain type pressure sensor in the above technology is a prior art, so there is no need to elaborate on how to collect and transmit data. At the same time, the first data acquisition module is also a prior art, and the way it integrates and analyzes data is a prior art (for example, integrating weight information, comparing the weight information with the maximum load-bearing value of the elevator, and reversely deducing the approximate range of the number of people in the elevator through the difference, that is, taking the average of the standard weight of men and the standard weight of women as the basic value, and dividing the weight information by the basic value to obtain the corresponding number of people. The corresponding number of people ±1 is the elevator passenger flow data. The derivation method and calculation method are both prior art and can be programmed to obtain an algorithm and added to the first data acquisition module or analysis module), so there is no need to elaborate on it.

[0011] The present invention is further provided that: the measuring structure includes an infrared sensor array for installation at the entrance and exit of the elevator room of the shopping mall, the infrared sensor array is composed of a second data acquisition module and a plurality of infrared sensors, the plurality of infrared sensors are communicatively connected to the second data acquisition module to transmit the infrared signal collected by the infrared sensor to the second data acquisition module so that the second data acquisition module analyzes the infrared signal and generates elevator room passenger flow data according to the analysis result, the second data acquisition module is communicatively connected to the wireless communication module to transmit the elevator room passenger flow data to the industrial control unit.

[0012] The benefits of adopting the above technical solution are: in the above technology, an infrared sensor array composed of multiple infrared sensors is installed at the entrance and exit of the shopping mall elevator room, which can realize accurate monitoring of people entering and exiting the elevator. Each infrared sensor performs its own function and captures the changes in blocking or reflecting infrared signals when people enter and exit from different angles. The infrared signal is transmitted to the second data acquisition module. This module processes massive signals with its powerful analysis ability to generate extremely accurate elevator room passenger flow data. Compared with traditional simple counting methods, such as relying solely on a single infrared sensor or manual counting, this counting structure can comprehensively and accurately record each entry and exit behavior of people, effectively avoiding data errors caused by factors such as occlusion and crowded people, and provides a solid foundation for subsequent various analyses and decisions based on passenger flow data. Reliable data foundation; through the collaborative work of the second data acquisition module and the wireless communication module, the generated elevator room passenger flow data can be transmitted to the industrial control unit in real time, so that the intelligent elevator passenger flow guidance device can quickly adjust the guidance strategy based on the latest passenger flow data. When the passenger flow of a certain elevator room surges, the system can promptly guide the crowd to other relatively idle elevator rooms through the ground guidance module, wall indication module and display module, etc., to achieve dynamic and balanced distribution of passenger flow. The dynamic guidance mechanism based on real-time and accurate data greatly improves the efficiency of elevator passenger flow guidance, reduces passenger waiting time, optimizes passengers' travel experience in the mall, and also improves the overall operation efficiency of the mall's vertical transportation system; the infrared sensor in the above technology is an existing technology, so its function and structure will not be described in detail.

[0013] The present invention further provides that: a plurality of the infrared sensors are arranged in a staggered manner.

[0014] The benefits of adopting the above technical solution are: in the above technology, several infrared sensors are staggered at the entrances and exits of the shopping mall elevator room, building a more meticulous monitoring network. Sensors at different positions can capture changes in infrared signals when people enter and exit from a unique perspective. Compared with regular arrangement, the staggered layout fills the monitoring blind spots, so that the entire entrance and exit area is within the monitoring range without omission. For example, in a scenario where people enter and exit frequently and there are complex behaviors such as pushing, shoving, and leaning, the staggered sensors can still track each person's movement trajectory in all directions, ensuring that there will be no missed detection due to changes in people's posture or deviations in the movement path, laying a solid foundation for the subsequent generation of accurate elevator room passenger flow data and ensuring the comprehensiveness and integrity of data collection.

[0015] The present invention is further provided that: the paving module includes an embedded groove preset on the shopping mall corridor along the opening direction of the shopping mall corridor, the embedded groove is divided into a main road and a plurality of branch roads, and the plurality of branch roads are connected to the main road; a plurality of light-transmitting glass plates are laid at the opening of the embedded groove, and the plurality of light-transmitting glass plates are arranged in sequence along the opening direction of the embedded groove; step surfaces for supporting and supporting the bottom walls of the light-transmitting glass plates on both sides are formed on the inner walls on both sides of the opening of the embedded groove; notches are formed at both ends of the plurality of light-transmitting glass plates for facilitating outside maintenance personnel to lift up the light-transmitting glass plates when the display module needs to be repaired or maintained; the radial cross-section of the notch is arc-shaped, and a flexible light-transmitting film is attached to the surface of the light-transmitting glass plate.

[0016] The benefits of adopting the above technical solution are: in the above technology, the embedded groove is opened along the shopping mall corridor, dividing it into the main road and branch road, which meets the complex pedestrian flow guidance needs of the shopping mall. When installing the relevant lines and equipment of the light display module, the wiring can be arranged in an orderly manner according to the planning of different branch roads leading to different elevator rooms, which greatly improves the installation efficiency, that is, each branch road corresponds to an elevator room; in the above technology, a number of light-transmitting glass plates are arranged in sequence at the opening of the embedded groove, and cooperate with the light display module to evenly transmit light to form a clear and continuous guiding path. The layout of the main road and the branch road can control the display of light in different areas through the light display module according to the passenger flow conditions of different elevator rooms, and accurately guide the direction of pedestrian flow. For example, during the peak period of the shopping mall, the light on the main road is brightened to guide most of the pedestrian flow, and the branch road corresponding to the idle elevator room is used to attract the crowd with unique color light to achieve efficient diversion; the light-transmitting glass plate is supported by the step surface and is firmly installed It is also easy to operate. When the display module needs repair or maintenance, the arc-shaped notches at both ends of the translucent glass plate provide a fulcrum for maintenance personnel, making it easy to lift the glass plate and quickly and conveniently access the equipment in the embedded groove, reducing maintenance time and labor costs, and effectively ensuring the normal operation of the ground guidance module. At the same time, the flexible translucent film affixed to the surface of the translucent glass plate can not only enhance the softness and uniformity of the light and avoid glare, but also diffusely reflect the light to a certain extent, so that the guiding light is still clearly visible in the complex lighting environment of the shopping mall, thereby comprehensively improving the guidance effect. In the above-mentioned technology, the step surface supports the translucent glass plate, disperses the pressure on the glass plate, and effectively prevents the glass plate from breaking due to pedestrian trampling, heavy objects crushing, etc. The flexible translucent film has good wear resistance and scratch resistance, can protect the surface of the translucent glass plate, reduce damage caused by friction and collision in daily use, and extend the service life of the laying module. In addition, the arc-shaped notch design avoids the risk of breakage due to concentrated force on the right-angle edges, further enhancing the structural stability of the light-transmitting glass panel, allowing the entire laying module to play a long-term and stable role in guiding passenger flow under the high-intensity use environment of the shopping mall, reducing the subsequent replacement and maintenance costs.

[0017] The present invention further provides that: the light display module includes an LED light strip arranged in a pre-buried groove, the opening and closing module is a relay control circuit group, and the relay control circuit group is composed of a relay, a control chip and a drive circuit.

[0018] The above technical solution is beneficial in that: the above technology uses LED light strips as the core components of the light display module. The LED light strips have low power consumption characteristics and can significantly reduce energy consumption compared to traditional lighting sources, which meets the needs of shopping malls for energy saving. With the relay control circuit group composed of relays, control chips and drive circuits as the opening and closing module, the control chip can accurately control the opening and closing of the relay according to the instructions from the overall module, and efficiently adjust the on and off and light-emitting state of the LED light strip through the drive circuit; at the same time, the LED light strip can be programmed to achieve a variety of colors, brightness and flashing mode changes, combined with the precise control of the relay control circuit group by the control chip, it can provide diversified guidance effects for different scenes. For example, for emergency evacuation scenes, it can be set to a fast flashing red light to attract the attention of the crowd; in daily passenger flow guidance, according to the status of different elevator rooms, green is used to indicate an idle elevator channel, and yellow is used to remind crowded elevator channels, which greatly enhances the intuitiveness and recognizability of the guidance information and optimizes the overall guidance effect; the relays, control chips and drive circuits in the above technology are all existing technologies, so they will not be described in detail.

[0019] The present invention is further provided that: the outer wall of the mounting plate is formed by a spraying process with a first font for visually guiding the flow of people to indicate that the elevator room is in a busy state, the inner wall of the mounting plate is formed by a spraying process with a second font for visually guiding the flow of people to indicate that the elevator room is in an idle state, the driving module includes a flip groove preset on the wall of the shopping mall elevator room, a driving motor installed in the wall of the shopping mall elevator room and a motor driver for controlling the opening and closing of the driving motor, the mounting plate is movably arranged in the flip groove, the output end of the driving motor is connected to the side wall of the mounting plate, a rotating shaft is rotatably connected between the mounting plate and the flip groove, and the motor driver is communicatively connected to the control module to control the opening and closing of the driving motor.

[0020] The advantages of adopting the above technical solution are: the outer wall and inner wall of the installation plate in the above technology are respectively sprayed with the first font indicating the busy state of the elevator room and the second font indicating the idle state, which can convey the real-time passenger flow information of the elevator room to pedestrians in an intuitive and eye-catching way. Whether approaching the elevator room from the front or passing by from the side, pedestrians can quickly obtain clear guidance information without complicated interpretation, which greatly improves the efficiency of information transmission. The intuitive visual guidance method helps pedestrians make decisions quickly and choose the appropriate elevator, reducing blind waiting and congestion caused by unclear information; through the drive module, the installation plate can be flexibly rotated in the flip groove. When the control module judges that the elevator room is in a busy state according to the data analysis of the overall planning module, the motor driver receives the instruction, controls the drive motor to start, and drives the installation plate to rotate, so that the side of the outer wall with the first font faces the flow of people, reminding pedestrians that the elevator room is busy. On the contrary, when the elevator room is idle, the installation plate flips and the second font on the inner wall is displayed to pedestrians. This design, which can switch guidance information in real time according to actual customer flow status, effectively improves the practicality and flexibility of the wall indication module, and better meets the dynamically changing customer flow guidance needs of shopping malls.

[0021] The present invention is further configured as follows: the display module includes an LED display screen, the transmission module includes a digital signage controller, several of the LED display screens are communicatively connected to the digital signage controller so that the digital signage controller projects the data transmitted by the computing module onto the LED display screen, and the digital signage controller is communicatively connected to the computing module to realize data transmission and reception.

[0022] The advantages of adopting the above technical solution are as follows: the LED display screen used in the above technology as the core component of the display module has high brightness, high contrast and clear image display effects. Whether in the bright ambient light of the shopping mall or in the darker light area, the data transmitted by the digital signage controller can be clearly presented to pedestrians. For example, the real-time passenger flow of each elevator room is displayed in the form of eye-catching numbers and intuitive charts. Pedestrians can easily obtain information at a long distance without the need for laborious interpretation, which greatly improves the visibility and readability of the information and facilitates pedestrians to quickly understand the passenger flow conditions of each elevator room and make reasonable choices; the digital signage controller, as the key to the transmission module, communicates with the calculation module to realize data transmission and reception, can quickly receive the latest passenger flow data generated by the calculation module, and timely project these data onto each LED display screen. In the process of dynamic changes in the passenger flow of the shopping mall, the display content can be updated in real time to ensure that pedestrians always obtain the latest and most accurate elevator room passenger flow information. The digital signage controller has strong versatility and compatibility and can be well adapted to the LED display screen and the calculation module. The digital signage controller in the above technology is an existing technology, so its structure and function will not be described in detail. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The overall operation process of the above technical solution is as follows: 1. Data collection stage: The infrared sensor array installed at the entrance and exit of the shopping mall elevator room starts working. Several staggered infrared sensors capture the changes in infrared signals when people enter and exit the elevator room, and transmit these signals to the second data acquisition module. The second data acquisition module analyzes the infrared signals to generate elevator room passenger flow data, and then transmits the data to the industrial control unit through the wireless communication module; at the bottom of the elevator car, the weighing device group between the weighing plate and the elevator car operates, and several strain gauge pressure sensors evenly distributed on the surface of the weighing plate detect the difference data generated by the weight of the passengers in the elevator, and transmit it to the first data acquisition module. The first data acquisition module analyzes these data to generate elevator passenger flow weight data, and also transmits the data to the industrial control unit through the wireless communication module.

[0035] 2. Data analysis stage: The industrial control unit receives the elevator room passenger flow data and elevator passenger flow weight data transmitted from the wireless communication module. The industrial control unit pre-stores standard elevator room passenger flow threshold data and standard elevator passenger flow weight threshold data. Through scientific algorithms, the received data is deeply compared and analyzed with the comparison data to accurately judge the passenger flow conditions of each elevator room, such as whether it exceeds the carrying standard, the difference from the normal passenger flow level, etc., and generates a start and close signal based on the comparison results. The server is connected to the industrial control unit for communication, and the elevator room passenger flow data and elevator passenger flow weight data are transmitted and stored in real time to provide data support for subsequent trend analysis and strategy adjustments.

[0036] 3. Guided execution stage: The programmable logic controller of the control module receives the start-stop signal from the industrial control unit. When the passenger flow in a certain elevator room is too large or overweight, the programmable logic controller controls the relay control circuit group (start-stop module), and then controls the color change of the LED light strip (display module) in the embedded groove. The LED light strip cooperates with the light-transmitting glass plate (laying module) laid on the embedded groove of the mall corridor to guide the flow of people to the idle elevator room by transmitting light of a specific color. For example, the path to the idle elevator room can be displayed as green light; at the same time, the programmable logic controller controls the motor driver according to the start-stop signal, and the motor driver controls the drive motor installed in the wall of the mall elevator room to start, and the output end of the drive motor drives the installation plate installed in the flip groove to flip. The outer wall of the mounting plate is sprayed with a first font indicating the busy state of the elevator room, and the inner wall is sprayed with a second font indicating the idle state. By flipping the corresponding font to display, visual guidance is provided to the flow of people; the digital signage controller (transmission module) is connected to the computing module for communication and receives information such as passenger flow data of the elevator room. The digital signage controller projects this data onto the LED display screen (display module) hanging at different ceiling positions of the shopping mall, and displays it to pedestrians in the form of intuitive numbers, charts, etc., so that pedestrians can understand the passenger flow of each elevator room from a distance and choose the appropriate elevator independently.
