Description

Technical Field

[0001] This invention belongs to the field of energy conservation and consumption reduction technology, and in particular relates to an energy conservation and consumption reduction system and method for airport display screens. Background Technology

[0002] Airport display screens are mainly categorized by service type, including check-in counter displays, departure guidance screens, boarding gate displays, security checkpoint displays, baggage sorting carousel displays, and baggage claim carousel displays. These screens display different service information at different times according to the needs of the business systems, such as flight departure information, flight arrival information, baggage transfer information, and baggage claim information. Currently, due to business needs and technical limitations, airport display screens are essentially on 24 / 7, even during off-peak hours, resulting in significant waste of power and a greatly shortened lifespan. However, given a fixed display power consumption and area, longer display durations lead to greater power consumption. Therefore, optimizing the on / off process of display screens based on different service content, reducing the duration of ineffective on / off states, and thus lowering power consumption and extending screen lifespan, while meeting the daily display service needs of airports, is a key issue that green airport initiatives are focusing on.

[0003] Chinese Patent (Publication No. CN112017588B, Publication Date August 31, 2020) discloses an energy-saving method and related apparatus for an LED display screen. The method includes: a terminal device receiving a start command, the start command instructing the terminal device to start the LED display device; sending a first control signal to a sending card device, the first control signal instructing the sending card device to start the sending card device; and, upon receiving a feedback signal, sending a second control signal to the LED display device, the second control signal instructing the sending card device to complete the start-up. The method and apparatus provided by the aforementioned patent, by adding a power management module to control the power-on sequence of the sending card and the LED display screen in start-up mode, and by shutting down the power supply of the display module of the LED display screen in standby mode through the power management module, greatly reduces resource waste in start-up and standby modes. However, this method cannot optimize the display screen switching process according to different business content of the airport, thereby reducing the power consumption of the display screen.

[0004] Chinese Patent (Publication No. CN112951150B, Publication Date 2021.01.29) discloses an energy-saving method, apparatus, device, and storage medium for an LED display screen. The method includes: collecting display data; updating the display data for the next row when the row scanning cycle enters the extinction time; calculating the signal pulse width of the display data in each column drive signal of the next row during the extinction time; the extinction time being the time interval between row scanning pulses of adjacent row scanning signals; determining the operating mode of the drive circuit of the column drive module corresponding to each column drive signal based on the signal pulse width, and adjusting the drive circuit of the column drive module corresponding to each column drive signal according to the operating mode. This patent increases the number of times the energy-saving mode of the column drive module is activated within the row scanning cycle by determining the signal pulse width of the display data in each column drive signal during the extinction time, thereby improving the energy efficiency of the LED display screen. However, it also optimizes the on / off process of the display screen according to the airport's business content, thus reducing the power consumption of the display screen and extending its service life. Summary of the Invention

[0005] To overcome the problems existing in related technologies, the present invention discloses an energy-saving and consumption-reducing system and method for airport display screens.

[0006] The technical solution is as follows: An energy-saving and consumption-reducing method for airport display screens includes the following steps: S1, the screen control terminal receives instructions from the switch control server in the background server, uses the serial port protocol to control the switch of the display screen, and at the same time feeds back the switch status of the display screen to the background server. S2, the management client receives data from the backend server and monitors the on / off status information of the display screen; according to the airport's business needs, the management client can change the rules for automatic on / off switching of the switch control server or manually turn the display screen on or off. S3, the backend server, is used to obtain business information stored in the database. This business information includes flight status information, security checkpoint opening and closing information, baggage carousel operation information, and boarding gate allocation information. The backend server generates different types of display screen on / off rule instructions and sends them to the screen control terminal to control the display screen to turn on or off. The backend server receives manual instructions, display screen information, and information transmitted from external systems, performs data processing and statistical analysis, and displays the data to users through the management client.

[0007] Furthermore, the backend server also includes an interface server, an application server, a database server, and a disk array; The control client connects to the application server via a network and is used for manual operation and data viewing; The application server connects to the interface server and the switch control server via a network to realize the uploading, distribution and processing of data. The switch control server is connected to the screen control terminal via the network to issue switch commands and upload status; the application server is connected to the database server; the database server (304) is connected to the disk array (305) to store data.

[0008] Furthermore, the interface server connects to the airport's production and operation system, integration system, and security inspection information system to obtain business information and send it to the application server; The interface server connects to the airport's production and operation system / integration system to obtain dynamic flight information, enabling the switch control server to calculate rules based on the automatic control mode and automatically control the check-in display screen, departure guidance screen, and boarding gate display screen. The interface server interfaces with the airport production and operation system / integration system and is also used to obtain usage information of baggage sorting carousel and baggage claim carousel, so that the switch control server can calculate rules according to the automatic control mode and automatically control the switch of baggage sorting carousel display screen and baggage claim carousel display screen. The interface server connects to the security inspection information system to obtain the switch information of the security inspection channel, enabling the switch control server to calculate rules and automatically control the switch of the security inspection channel display screen.

[0009] Furthermore, the application server publishes information through a message middleware, and the switch control server and multiple management clients receive the same set of messages; The application server receives business information transmitted by the interface server, processes it, stores it in the database server, and sends the processed business data to the management client and the switch control server.

[0010] Furthermore, the switch control server includes a rule engine, which obtains dynamic flight information, security checkpoint switch information, baggage carousel operation information, and flight gate allocation information stored in the database through the application server to generate different types of display screen switch rule instructions, which are then sent to the screen control terminal to control the display screen to turn on or off; the display screen switch rule instructions include power off instructions and power on instructions. The disk array is assembled into a disk system using multiple independent disks to store the business information of the database server.

[0011] Furthermore, the rule engine extracts frequently changing business rules from the program and places them in a rule base for management and modification; The rule engine includes two automatic control modes: The first mode sets a uniform on / off time based on the type of display screen; The second mode dynamically controls the on / off time of the display screen by connecting to external system business data, depending on the different airport display services.

[0012] In the first mode, setting uniform on and off times based on display screen type includes: setting uniform on and off times; users set uniform on and off times for the display screen in the management client, and the corresponding type of display screen will be turned on and off at the corresponding time each day.

[0013] In the second mode, the on / off time of the display screen is dynamically controlled based on the different airport display services and the business data from the external system. Specifically, this includes: (a) Flight information display systems, including check-in displays, departure guidance displays, and gate displays, are controlled according to the following rules: Check-in display screens: Connect to the airport's production and operation system or integrated system to obtain dynamic flight information for the day, calculate the check-in counter display screens one hour before the earliest departing flight's check-in begins, and turn them off one hour after the latest departing flight's check-in ends; Departure Guidance Screen: Connects to the airport's production and operation system or integrated system to obtain dynamic flight information for the day, calculates the departure guidance screen to be turned on one hour before the earliest departure flight's check-in begins, and turned off one hour after the latest departure flight's check-in ends; Gate Display Screen: Connects to the airport's production and operation system or integrated system to obtain dynamic flight information for the day, calculates the time period for the current gate to be used, and turns off the gate display screen if there are no flights within one hour before or after the current time; otherwise, turns on the gate display screen.

[0018] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Example 1, such as Figures 1-2 As shown, an embodiment of the present invention provides an energy-saving and consumption-reducing system for airport displays, comprising: Screen control terminal 1 is deployed on the industrial computer of the display screen. It is used to connect to the switch control server 302, receive instructions sent by the back-end server 3, control the switch of the display screen using the serial port protocol, and at the same time, report the switch status of the display screen to the back-end server 3. The management client 2 is used to monitor the on / off status information of the display screen; according to the airport's business needs, the management client 2 can be used to change the rules for automatic on / off switching of the switch control server 302 or manually turn the display screen on or off. The backend server 3 is used to obtain business information stored in the database, including flight status information, security checkpoint opening and closing information, baggage carousel operation information, and boarding gate allocation information. The backend server 3 generates different types of display screen opening and closing rule instructions and sends them to the screen control terminal 1 to control the opening or closing of the display screen. The backend server 3 receives manual instructions, display screen information and information transmitted from external systems, performs data processing and statistical analysis, and displays the data to users through the management client 2.

[0020] The backend server 3 includes an interface server 301, a switch control server 302, an application server 303, a database server 304, and a disk array 305. The control client 2 is connected to the application server 303 via the network and is used for manual operation and viewing of various data. The application server 303 is connected to the interface server 301 and the switch control server 302 via a network to realize the uploading, distribution and processing of data. The switch control server 302 is connected to the screen control terminal 1 via a network to issue switch commands and upload status; the application server 303 is connected to the database server 304; the database server 304 is connected to the disk array 305 to store data.

[0021] The interface server 301 connects to the airport production and operation system / integration system and the security inspection information system to obtain business information and send it to the application server 303.

[0022] Specifically, the interface server 301 connects to the airport production and operation system or integrated system to obtain dynamic flight information, so that the switch control server 302 calculates rules according to the automatic control mode and automatically controls the check-in display screen, departure guidance screen and boarding gate display screen. The automatic control mode includes the following two types: The first mode sets a uniform on / off time based on the type of display screen; The second mode dynamically controls the on / off time of the display screen by connecting to external system business data, depending on the different airport display services.

[0023] The first mode, which sets uniform on and off times according to the display screen type, includes: setting uniform on and off times. The user sets a uniform on time and a uniform off time for the display screen in the management client 2, so that the display screen of the corresponding type will be turned on and off at the corresponding time every day.

[0024] The second mode dynamically controls the on / off time of the display screen based on the different airport display services and connects to external system business data. Specifically, this includes: (a) Flight information display systems, including check-in displays, departure guidance displays, and gate displays, are controlled according to the following rules: Check-in display screens: Connect to the airport's production and operation system or integrated system to obtain dynamic flight information for the day, calculate the check-in counter display screens one hour before the earliest departing flight's check-in begins, and turn them off one hour after the latest departing flight's check-in ends; Departure Guidance Screen: Connects to the airport's production and operation system or integrated system to obtain dynamic flight information for the day, calculates the departure guidance screen to be turned on one hour before the earliest departure flight's check-in begins, and turned off one hour after the latest departure flight's check-in ends; Gate Display Screen: Connects to the airport's production and operation system or integrated system to obtain dynamic flight information for the day, calculates the time period for the current gate to be used, and turns off the gate display screen if there are no flights within one hour before or after the current time; otherwise, turns on the gate display screen. (b) Baggage display screens, including baggage claim carousel displays and baggage sorting carousel displays, are controlled according to the following rules: Baggage claim carousel display screen: Connects to the airport's production and operation system or integrated system to obtain dynamic flight information for the day, calculates the time when the earliest arriving flight of the day will be turned on, and turns off the display screen one hour after the latest arriving flight of the day will be turned off. Baggage sorting carousel display screen: It connects to the airport's production and operation system or integrated system to obtain the allocation and usage information of baggage sorting carousels, calculates that the display screen will be turned on one hour before the start of the baggage sorting task for the flight using the baggage sorting carousel display screen; and turned off the display screen half an hour after the end of the sorting task for the last flight. (c) The rules for controlling the security checkpoint display screen are as follows: Connect to the security check information system to obtain the open and closed status of the security checkpoint. When the security checkpoint is open, turn on the display screen of the current security checkpoint; when the security checkpoint is closed, turn off the display screen of the current checkpoint.

[0025] The interface server 301 is also used to connect to the airport production and operation system or integrated system to obtain the usage information of the baggage sorting carousel and the baggage claim carousel, so that the switch control server 302 can calculate the rules and automatically control the switch of the baggage sorting carousel display screen and the baggage claim carousel display screen. The interface server 301 is also used to connect to the security inspection information system to obtain the switch information of the security inspection channel, so that the switch control server 302 can calculate the rules according to the automatic control mode and automatically control the switch of the security inspection channel display screen.

[0026] The application server 303 publishes information through a message middleware, and the switch control server 302 and multiple management clients 2 receive the same set of messages.

[0027] The switch control server 302 includes a rule engine, which obtains dynamic flight information, security checkpoint switch information, baggage carousel operation information, and flight gate allocation information stored in the database through the application server 303 to generate different types of display screen switch rule instructions, which are then sent to the screen control terminal 1 to control the display screen to turn on or off.

[0028] The display screen switch rule commands sent by the switch control server 302 include power-off commands and power-on commands. The power-off commands are shown in Table 1 below.

[0029] Table 1 Power-off Command List

[0030] The power-on instructions are shown in Table 2 below.

[0031] Table 2 Power-on Command Table

[0032] The screen control terminal 1 can also obtain the on / off information of the display screen and transmit it to the management client 2 through the message middleware in the application server 303. Airport management personnel can view the on / off status of the display screen through the management client 2, and can also directly send on / off commands to the display screen when airport operations require it; these commands are transmitted to the screen control terminal 1 through the message middleware in the application server 303 to directly control the on / off status of the display screen.

[0033] The disk array 305, officially known as Redundant Array of Independent Disks (RAID), is a disk system assembled from multiple independent disks to store the business information of the database server 304, thereby achieving better storage performance and higher reliability than a single disk.

[0034] Through the above embodiments, the present invention, while meeting the daily display business needs of airports, intelligently controls the opening and closing of check-in displays, departure guidance displays, boarding gate displays, baggage claim carousel displays, baggage sorting carousel displays, and security checkpoint displays, optimizes the display screen switching process, saves airports a lot of electricity, extends the expected service life of the displays, reduces airport operating costs, and helps airports achieve green development by saving costs.

[0035] For example, such as Figure 2 As shown in the embodiment of the present invention, the airport display screen energy-saving and consumption-reducing system has an interface server 301 that interfaces with the airport production and operation system or integration system and security inspection information system to obtain different business information. This information is then transmitted to the switch control server 302 via the message middleware of the application server 303. The switch server 302 calculates the on / off state commands for different displays based on the selected automatic control mode. The screen control terminal 1 on the display screen industrial control computer receives the commands from the switch control server 302 and uses the RS232 serial port protocol to control the on / off state of the display screen. Simultaneously, the status of the display screen is fed back to the management client 2 via the message middleware of the application server 303. Users can view the on / off status of different airport displays on the management client 2 and switch the automatic control mode of the automatic on / off switch on the switch control server 302 as needed, or manually turn the display screen on / off.

[0036] Example 2, as Figure 3 As shown in the figure, this invention also provides a method for energy saving and consumption reduction of airport display screens, including the following steps: S1, the screen control terminal 1 receives the instruction from the switch control server 302 in the background server 3, uses the serial port protocol to control the switch of the display screen, and at the same time feeds back the switch status of the display screen to the background server 3. S2, the management client 2 receives data from the backend server 3 and monitors the on / off status information of the display screen; according to the airport's business needs, the management client 2 can change the rules for automatic on / off switching of the switch control server 302 or manually turn the display screen on or off. S3, the backend server 3, is used to obtain business information stored in the database. The business information includes flight status information, security checkpoint opening and closing information, baggage carousel operation information, and boarding gate allocation information. The backend server 3 generates different types of display screen opening and closing rule instructions and sends them to the screen control terminal 1 to control the opening or closing of the display screen. The backend server 3 receives manual instructions, display screen information and information transmitted from external systems, performs data processing and statistical analysis, and displays the data to the user through the management client 2.

[0037] In step S3 of this embodiment of the invention, the background server 3 includes an interface server 301, a switch control server 302, an application server 303, a database server 304, and a disk array 305. The management client 2 connects to the application server 303 via the network for manual operation and viewing of various data; the application server 303 connects to the interface server 301 and the switch control server 302 via the network to upload, distribute, and process data; the switch control server 302 connects to the screen control terminal 1 via the network to distribute switch commands and upload status; the application server 303 connects to the database server 304.

[0038] The interface server 301 interfaces with the airport production and operation system or integrated system and the security check information system to obtain business information and send it to the application server 303. Specifically, the interface server 301 interfaces with the airport production and operation system or integrated system to obtain dynamic flight information, enabling the switch control server 302 to calculate rules and automatically control the check-in display screen, departure guidance screen, and boarding gate display screen; it interfaces with the airport production and operation system or integrated system to obtain usage information of baggage sorting carousels and baggage claim carousels, enabling the switch control server 302 to calculate rules and automatically control the switching of baggage sorting carousel display screens and baggage claim carousel display screens; and it interfaces with the security check information system to obtain the switching information of security check lanes, enabling the switch control server 302 to calculate rules and automatically control the switching of security check lane display screens.

[0039] The application server 303 publishes information through a message middleware, and the switch control server 302 and multiple management clients 2 receive the same set of messages.

[0040] The application server 303 receives the business information transmitted by the interface server 301, processes it, stores it in the database server 304, and sends the processed business data to the management client 2 and the switch control server 302.

[0041] The management client 2 receives business data and displays it to the user through the user interface.

[0042] The switch control server 302 includes a rule engine, which obtains dynamic flight information, security checkpoint switch information, baggage carousel operation information, and flight gate allocation information stored in the database through the application server 303 to generate different types of display screen switch rule instructions, which are then sent to the screen control terminal 1 to control the display screen to turn on or off.

[0043] Specifically, the rule engine is a component embedded in an information system that extracts frequently changing business rules from the program and places them in a rule base for management and modification.

[0044] Specifically, it includes: The rule engine involves two automatic control modes: one is to set uniform on and off times based on the type of display screen, and the other is to dynamically control the on / off time of the display screen by connecting to external system business data according to the different airport display services.

[0045] For the first mode, set a unified start and stop time: users can set the unified start time of the display screen to 4:00 AM every day and the unified stop time to 0:00 AM every day in the management client 2. Then the corresponding type of display screen will be turned on and off at the corresponding time every day.

[0046] For the second mode, based on the different airport display services, the on / off time of the display screen is dynamically controlled by connecting to external system business data, specifically including: (a) Flight information display system displays, which are further divided into check-in displays, departure guidance displays, and boarding gate displays, etc., are controlled according to the following rules: Check-in display screens: Connect to the airport's production and operation system or integrated system to obtain dynamic flight information for the day, calculate the check-in counter display screens one hour before the earliest departing flight begins check-in, and turn them off one hour after the latest departing flight ends check-in.

[0047] Departure Guidance Screen: Connects to the airport's production and operation system or integrated system to obtain dynamic flight information for the day, calculates the departure guidance screen to be turned on one hour before the earliest departure flight's check-in begins, and turned off one hour after the latest departure flight's check-in ends.

[0048] Gate Display Screen: Connects to the airport's production and operation system or integrated system to obtain dynamic flight information for the day, calculates the time period for the current gate to be used, and turns off the gate display screen if there are no flights within one hour before or after the current time; otherwise, turns on the gate display screen.

[0049] (b) Baggage display screens, which are further divided into baggage claim carousel displays and baggage sorting carousel displays, are controlled according to the following rules: Baggage claim carousel display screen: It connects to the airport's production and operation system or integrated system to obtain dynamic flight information for the day, calculates that the display screen will be turned on half an hour before the arrival of the earliest arriving flight of the day, and turned off one hour after the arrival of the latest arriving flight of the day.

[0050] Baggage sorting carousel display screen: It connects to the airport's production and operation system or integrated system to obtain the allocation and usage information of baggage sorting carousels, calculates that the display screen will be turned on one hour before the start of the baggage sorting task for the flight using the baggage sorting carousel display screen, and turned off half an hour after the end of the sorting task for the last flight.

[0051] (c) The rules for controlling the security checkpoint display screens are as follows: Connect to the security check information system to obtain the open and closed status of the security check lanes. When a security check lane is open, turn on the display screen of the current security check lane; when a security check lane is closed, turn off the display screen of the current lane.

[0052] Users can configure the automatic control mode of the display screen in the rule engine on the switch control server 302 through the management client 2. This mode information can be sent to the switch control server 302 through the message middleware on the application server 303.

[0053] The switch control server 302 synchronizes basic information of all displays through the application server 303, including display number, display type, industrial control computer IP, and bound physical location points (such as check-in counter number, boarding gate number, security checkpoint number, baggage carousel number, etc.). Based on the user-selected display switch mode and the business information sent by the application server 303, the switch control server 302 calculates the switch status information (including industrial control computer IP, display status, etc.) of the corresponding type of display and sends this switch information to the screen control terminal 1 of the corresponding industrial control computer.

[0054] For example, the second mode, such as Figure 4 As shown, the method for automatically controlling the check-in display screen includes: Interface server 301 connects to the production and operation system to obtain flight dynamic information. Whenever there is a change in flight duty information, including check-in time and check-in counter information, the switch control server 302 receives this information and can group the flights according to the check-in counter numbers in the flight information. It then calculates the time one hour before the start of check-in for the earliest departing flight and the time one hour after the end of check-in for the latest departing flight for each check-in counter number. By combining this with the physical location point bound to the display screen information to the corresponding check-in counter number, the server can obtain the opening and closing times of the check-in display screen.

[0055] After receiving the time information for the display screen to turn on and off, the screen control terminal 1 installed on the industrial computer of the display screen first compares whether the IP address in the information is the IP address of the industrial computer. If not, the screen control terminal 1 does not perform any processing. If the IP address in the information is the IP address of the industrial computer, the screen control terminal 1 sends an RS232 serial port command according to the display screen status in the information to control the display screen to turn on or off.

[0056] The above method can be further understood as follows: Interface server 301 connects to the airport's production and operation system or integrated system and security check information system to obtain business information and sends it to application server 303. Application server 303 receives the business information, processes it, stores it in database server 304, and sends the processed business data to management client 2 and switch control server 302. Management client 2 receives the business data and displays it to the user through the user interface. The user can configure the automatic control mode of the display screen in the rule engine on switch control server 302 through management client 2. This mode information can be sent to switch control server 302 through message middleware on application server 303. Switch control server 302 synchronizes the basic information of all display screens through application server 303, including display screen type, industrial control computer IP, and bound physical location points (such as boarding gate number, security check channel number, baggage carousel number, etc.). The switch control server 302 calculates the on / off status information (including the industrial control computer IP, display status, etc.) of the corresponding type of display screen based on the user-selected display screen on / off mode and the business information sent by the application server 303, and sends this on / off information to the screen control terminal 1 of the industrial control computer corresponding to the display screen. After receiving the information, the screen control terminal 1 compares whether the IP in the information is the IP of the industrial control computer. If not, the screen control terminal 1 does not process it; if the IP in the comparison information is the IP of the industrial control computer, the screen control terminal 1 sends an RS232 serial port command according to the display status in the information to control the display screen to turn on or off.

[0057] For example, screen control terminal 1 can obtain the on / off information of the display screen and transmit it to management client 2 through the message middleware in application server 303. Airport management personnel can view the on / off status of each display screen through management client 2. When airport operations require it, they can also directly send on / off commands to the display screen, which are transmitted to screen control terminal 1 through the message middleware in application server 303 to directly control the display screen's on / off status.

[0058] As can be seen from the above embodiments, the airport display screen energy-saving and consumption-reducing system and method of the present invention can significantly reduce the duration of the display screen being on while meeting the daily display business needs of the airport. This reduces power consumption and extends the lifespan of the display screen, thereby reducing airport operating costs to a certain extent and possessing significant commercial value. Traditional display screen energy-saving solutions focus on the display screen itself, optimizing component composition and brightness to achieve energy saving. The airport display screen energy-saving and consumption-reducing system and method of the present invention optimizes the on / off business process of the external display screen, further reducing power consumption and extending the lifespan of the display screen.

[0059] Existing airport display screens are distributed across various areas of the airport, covering a large area. Manual switching and maintenance are very inconvenient and require a great deal of manpower. Often, the screens are kept on 24 hours a day, which consumes a lot of electricity. The technical solution of this invention allows for manual remote control of the display screens to be turned on and off. In automatic mode, the display screens can be turned on and off automatically according to set rules, effectively solving the above problems.
