Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning system control, and in particular to a method, device and equipment for controlling an air-conditioning system of an airport terminal. Background Art

[0002] As the core area for passenger gathering and distribution, the environmental comfort of airport terminals directly affects passengers' travel experience. As key equipment for terminal environmental control, air conditioning systems consume a significant proportion of the entire terminal's energy consumption.

[0003] In related technologies, air conditioning systems in airport terminals are typically controlled based on a fixed timeline of passenger flow distribution within the terminal building. Alternatively, sensors are used to detect passenger flow distribution within local areas of the terminal building to control the air conditioning system. Flight delays or cancellations can cause changes in passenger flow within the airport building. Controlling the air conditioning system based on fixed timeline passenger flow distribution cannot adapt to flight fluctuations and, when passenger flow increases, cannot meet passenger comfort requirements. Detecting passenger flow distribution in local areas of the terminal building cannot accurately measure the overall passenger flow distribution, resulting in inaccurate air conditioning system control.

[0004] Therefore, the above control methods lack accurate prediction and response to the dynamic behavior of passengers, which may easily lead to energy waste of the air conditioning system of the airport terminal or insufficient comfort for passengers. Summary of the Invention

[0057] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0058] According to an embodiment of the present invention, an embodiment of a method for controlling an airport terminal air conditioning system is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0059] In this embodiment, a method for controlling an airport terminal air conditioning system is provided, which can be used for computer devices such as mobile phones, tablet computers, desktop computers, portable notebooks, servers, etc. Figure 1 As shown, the airport terminal includes: a check-in hall 11, a security check area 12 and a waiting hall 13, wherein the waiting hall 13 includes n sub-areas 131, the nth sub-area includes m boarding gates 1311, and the mth boarding gate includes i passengers waiting for boarding, n≥1, i≥1, m≥1, Figure 2 is a flow chart of a method according to an embodiment of the present invention, such as Figure 2 As shown, the process includes the following steps:

[0060] Step S201: Obtain the number of passengers in the check-in hall within a preset time period, the number of passengers in the security inspection area within a preset time period, and the number of passengers in the nth sub-area of the terminal hall within a preset time period.

[0061] Specifically, the check-in hall is the area where passengers undergo check-in procedures, baggage collection, and other passenger services. The security check area is where passengers undergo baggage and body checks before entering the terminal. The departure lounge is where passengers go through various formalities and take a short break before and after their flight. A preset time period is a pre-set time period that facilitates passenger flow statistics within a specific timeframe. This preset time period can be flexibly applied based on actual circumstances.

[0062] In some specific examples, the number of passengers in the nth sub-area of the check-in hall, security area, or waiting hall within a preset time period includes but is not limited to calculations through high-definition cameras, infrared thermal imaging sensors, Wi-Fi positioning devices, mathematical formulas, etc.

[0063] In some optional implementations, the number of passengers in the check-in hall during a preset time period is calculated using the following formula (1):

[0064]

[0065] Among them, N checkin is the number of passengers in the check-in hall during the preset time period, V checkin is the number of passengers who complete check-in per unit time, t stay is the average length of time passengers spend in the check-in hall. is the passenger's companionship coefficient, S checkin is the staff density in the check-in hall, S checkin It is the area of the check-in hall.

[0066] In the above formula (1), V checkin Can be obtained from the airport check-in system; stay It can be calculated from the difference between the passenger's check-in time and security check time. The check-in time and security check time can be obtained from the check-in system and the security check system; The general value is 1.2, which can also be modified through on-site investigation; S checkin This can be obtained through airport staff on duty.

[0067] In some other optional implementations, the number of passengers in the security inspection area within a preset time period is calculated using the following formula (2):

[0068] The number of passengers in the security inspection area during the preset period is calculated using the following formula:

[0069]

[0070] Among them, N security is the number of passengers in the security inspection area during the preset period, V chekcin is the passenger check-in rate, V security is the passenger screening rate, S security is the number of employees in the security inspection area, t is the cumulative time, t1 is the lower limit time, and t2 is the upper limit time.

[0071] In the above formula (2), V chekcin Can be obtained from the passenger check-in system, V security Can be obtained from the passenger security system, S security This information can be obtained from the airport security schedule.

[0072] In some other optional implementations, obtaining the number of passengers in the nth sub-area of the terminal hall within a preset time period includes:

[0073] Step a1: Obtain the time when the i-th passenger arrives at the m-th boarding gate in the n-th sub-area.

[0074] In some specific examples, the time when the i-th passenger arrives at the m-th boarding gate of the n-th sub-area includes, but is not limited to, being obtained by timing with a timing device or being calculated using a mathematical formula.

[0075] In some optional implementations, the time when the i-th passenger arrives at the m-th boarding gate in the n-th sub-area is obtained by the following formula (3):

[0076]

[0077] In the above formula (3), t m,i,arrive is the time when the i-th passenger arrives at the m-th boarding gate, t i,security is the time when the i-th passenger passes through the security inspection area, which can be obtained from the security inspection system. m is the walking distance from the security check area exit to the mth boarding gate, which can be obtained from drawings or on-site measurements; v is the baseline walking speed, usually 1-1.2 m / s; is the age-adjusted coefficient for walking speed, which is 1 for those under 45 years old, 0.8 for those aged 45-60 years old, and 0.6 for those aged 60 years and above; The luggage adjustment coefficient for the travel speed is 1 for no luggage, 0.9 for one piece of luggage, 0.8 for two pieces of luggage, and 0.6 for three or more pieces of luggage. The amount of luggage carried by the passenger can be obtained through the check-in system and the security inspection system.

[0078] Step a2: Get the departure time of the flight at the mth boarding gate.

[0079] Specifically, the flight departure time for gate m can be obtained from the airport server. When the flight forecast changes (such as flight delays or cancellations), the backend server automatically adjusts the flight departure time to ensure that the number of passengers in the corresponding area is correctly calculated.

[0080] Step a3: Based on the arrival time of the i-th passenger at the m-th boarding gate in the n-th sub-area and the departure time of the flight at the m-th boarding gate, the number of passengers in the n-th sub-area of the terminal hall during a preset time period is counted. When the flight boarded by the i-th passenger takes off, the number of passengers at the m-th boarding gate is reset to zero.

[0081] For example, the number of passengers in the nth sub-area of the terminal hall during the preset time period is represented by N gate,i (t) is represented by the following formula (4).

[0082]

[0083] in, is an indicator function (1 if the condition is met, 0 otherwise)

[0084] Clear condition, when the flight takes off (t a =t m，depart ), all passengers at the mth gate are cleared, that is, N gate,i (t)=0, when t a >t m，depart .

[0085] In the above formula (4), t m，i,arrive is the time when passenger i arrives at the mth gate, t m，depart The departure time of the flight at gate m, N gate,i (t) is the number of passengers in the nth sub-area of the terminal hall during the preset time period.

[0086] In some optional implementations, detection equipment is installed at key locations in the target area to detect the number of passengers at the key locations, and the number of passengers in the target area within a preset time period is corrected.

[0087] In order to prevent errors in the calculation results of the above formula, passenger flow monitoring equipment such as high-definition cameras, infrared thermal imaging sensors, and Wi-Fi positioning devices can be deployed at key locations in the terminal to collect real-time passenger flow data for calibration and correction of the above calculation results.

[0088] Step S202: Obtain basic climate parameters and basic load parameters.

[0089] In some specific examples, the basic climate parameters include: outdoor temperature influence coefficient, outdoor temperature, and indoor temperature.

[0090] The outdoor temperature influence coefficient can be expressed as k w It can be measured, for example, by field testing or simulated using the simulation software EnergyPlus. The outdoor temperature and indoor temperature can be detected by temperature sensors. The outdoor temperature can be measured using T out Indoor temperature can be expressed as T set express.

[0091] In some specific examples, the basic load parameters include: basic air-conditioning load, average passenger load, and basic number of passengers corresponding to the basic load.

[0092] The basic air conditioning load can be expressed as Q base The average passenger load can be expressed as C p The number of basic passengers under the basic load can be expressed as N base Indicates the average passenger load C p It can also be measured through on-site testing or simulated through the simulation software EnergyPlus.

[0093] Step S203, obtaining the load demand parameters of the air conditioning system of the target area within the preset time period according to the number of passengers in any target area among the check-in hall, security inspection area and nth sub-area of the waiting hall within the preset time period, as well as the basic climate parameters and basic load parameters.

[0094] For example, when the target area is the check-in hall, the load demand parameter Q of the air conditioning system of the check-in hall during the preset period is obtained according to the number of passengers in the check-in hall during the preset period, the basic climate parameters and the basic load parameters. t1 .

[0095] When the target area is the security inspection area, the load demand parameter Q of the air conditioning system in the security inspection area during the preset period is obtained according to the number of passengers in the security inspection area during the preset period, the basic climate parameters and the basic load parameters. t2 .

[0096] When the target area is the nth sub-area of the terminal hall, the load demand parameter Q of the air conditioning system of the security inspection area in the preset period is obtained according to the number of passengers in the nth sub-area of the terminal hall during the preset period, the basic climate parameters and the basic load parameters. t3 .

[0097] In some optional implementations, the load demand parameter of the air-conditioning system in the target area within a preset period is obtained by the following formula (5):

[0098] Q t =Q base +C p ×(N t -N base )+k w ×(T out -T set )(5)

[0099] Among them, Q t is the load demand parameter of the air conditioning system in the target area during the preset period, Q base is the basic air conditioning load, C p is the average passenger load, k w is the outdoor temperature influence coefficient, N t is the number of passengers in the target area during the preset time period, N base is the basic number of passengers corresponding to the basic load, T out is the outdoor temperature, T set It is the indoor temperature.

[0100] In other optional implementations, the load demand parameters of the air-conditioning system in the target area within a preset time period are predicted using a pre-trained load demand prediction model.

[0101] In other optional implementations, the load demand parameters of the air-conditioning system in the target area within a preset time period may also be simulated by simulation software.

[0102] Step S204, regulating the air conditioning system of the target area according to the number of passengers in any target area among the check-in hall, security inspection area and nth sub-area of the waiting hall within the preset time period and the load demand parameter of the air conditioning system of the target area within the preset time period.

[0103] Because traditional methods typically control air conditioning systems based on fixed, timed passenger flow patterns within airport terminals, they are unable to adapt to flight fluctuations and, when passenger traffic increases, fail to meet passenger comfort requirements. Furthermore, they only monitor passenger flow patterns in local areas of the terminal, failing to capture the overall distribution of passenger flow within the terminal, resulting in inaccurate air conditioning system control. Traditional methods lack the ability to accurately predict and respond to passenger dynamic behavior, which can lead to wasted energy in the airport terminal's air conditioning system and inadequate passenger comfort.

[0104] Therefore, the embodiment of the present disclosure combines the number of passengers in any target area of the check-in hall, security area and nth sub-area of the waiting hall within a preset time period, and the load demand parameters of the air-conditioning system of the target area within the preset time period, and can flexibly adapt to changes in passenger flow in the airport terminal, and adapt the corresponding control method of the corresponding air-conditioning system, thereby realizing precise control of the air-conditioning system of the target area, and ultimately saving energy consumption of the air-conditioning system of the airport terminal.

[0105] In some optional embodiments, step S204, regulating the air conditioning system of any target area among the check-in hall, the security inspection area, and the nth sub-area of the terminal hall, based on the number of passengers in a preset time period and the load demand parameter of the air conditioning system of the target area in the preset time period, includes:

[0106] When Q t >Q base And N t >N base When the target area is in the hot and cold zone, the air supply volume and fresh air volume of the air conditioning system are increased;

[0107] Heat transfer typically refers to the amount of heat transferred. In summer, passengers place greater demand on the air conditioning system for cooling, resulting in a lower heat transfer rate. In winter, passengers place greater demand on the air conditioning system for heating, resulting in a higher heat transfer rate. Fresh air volume refers to the amount of fresh air introduced into a specific space per unit time and is often used to measure the ventilation capacity of a ventilation system.

[0108] Under this control condition, the increase in the number of passengers in the target area during the preset time period has exceeded the base passenger number corresponding to the base load. Simultaneously, the load demand parameters of the target area's air conditioning system during the preset time period also exceed the base air conditioning load. Passengers in the target area have increased their demand for the cooling and heating capacity, supply air volume, and fresh air volume of the target area's air conditioning system. To meet passenger comfort requirements, the cooling and heating capacity, supply air volume, and fresh air volume of the target area's air conditioning system are increased.

[0109] Or, when Q t base And N t <N base When the target area is affected, reduce the cooling and heating capacity, supply air volume and fresh air volume of the air conditioning system.

[0110] Under this control condition, the number of passengers in the target area during the preset time period has decreased, falling below the baseline passenger number corresponding to the base load. Simultaneously, the load demand parameters for the target area's air conditioning system during the preset time period are also lower than the base air conditioning load. This also indicates that passengers in the target area are demanding less cooling and heating capacity, supply air volume, and fresh air volume for the air conditioning system. To conserve energy consumption in the target area's air conditioning system, these cooling and heating capacity, supply air volume, and fresh air volume are reduced.

[0111] Or, when Q t =Q base And N t =N base When the target area is controlled, the cooling and heating capacity, supply air volume and fresh air volume of the air conditioning system remain unchanged;

[0112] Under this control condition, the target area's passenger count fluctuates minimally during the preset time period, remaining constant relative to the baseline passenger count under the base load. Furthermore, the target area's air conditioning system load demand parameters during the preset time period are equal to the base air conditioning load. This also indicates that passengers within the target area maintain constant demands for cooling, heating, air flow, and fresh air volume from the air conditioning system. In this scenario, it's crucial to conserve energy consumption within the target area's air conditioning system while also meeting the comfort requirements of passengers within the target area. Therefore, the cooling, heating, air flow, and fresh air volume of the target area's air conditioning system remain constant.

[0113] Or, when Q t >Q base And N t =N base When the target area is in the cold zone, the cooling and heating capacity and air supply volume of the air conditioning system are increased and the fresh air volume of the air conditioning system in the target area is controlled to remain unchanged; or

[0114] ​Under this control condition, the number of passengers in the target area during the preset time period is the same as the base passenger number under the base load. However, the load demand parameter for the target area's air conditioning system during the preset time period is greater than the base air conditioning load. This also indicates that although the number of passengers in the target area during the preset time period has not fluctuated, the load demand on the target area's air conditioning system during the preset time period has increased. In this case, it is necessary to both conserve the energy consumption of the target area's air conditioning system and meet the comfort requirements of the target area's passengers. Therefore, the cooling and heating capacity and air supply volume of the target area's air conditioning system are increased, while the fresh air volume of the target area's air conditioning system is kept constant.

[0115] Or, when Q t base And N t =N base When the target area is in the cold zone, the cooling and heating capacity and air supply volume of the air conditioning system in the target area are reduced, and the fresh air volume of the air conditioning system in the target area is controlled to remain unchanged.

[0116] Under this control condition, the number of passengers in the target area during the preset time period is the same as the base passenger number under the base load. However, the load demand parameter for the target area's air conditioning system during the preset time period is less than the base air conditioning load. This also indicates that although the number of passengers in the target area during the preset time period has not fluctuated, the load demand on the target area's air conditioning system during the preset time period has decreased. In this case, it is necessary to both conserve the energy consumption of the target area's air conditioning system and meet the comfort requirements of the target area's passengers. Therefore, the cooling and heating capacity and air supply volume of the target area's air conditioning system are reduced, while the fresh air volume of the target area's air conditioning system is maintained constant.

[0117] Or, when Q t =Q base And N t >N base When the target area is in the hot zone, the fresh air volume of the air conditioning system is increased, and the cooling and heating volume and air supply volume of the air conditioning system in the target area are controlled to remain unchanged.

[0118] Under this control condition, the target area's passenger count fluctuates more during the preset time period, and the load demand parameter for the target area's air conditioning system during the preset time period exceeds the base air conditioning load. This also indicates that while the passenger load demand for the target area's air conditioning system remains unchanged during the preset time period, the number of passengers in the target area during the preset time period has increased. In this case, it is necessary to both conserve the target area's air conditioning system's energy consumption and meet the comfort requirements of its passengers. Therefore, the target area's air conditioning system's fresh air volume is increased, while the cooling, heating, and supply air volumes are maintained constant.

[0119] Or, when Q t =Q​base And N y <N base When the target area is in the hot zone, the fresh air volume of the air conditioning system is reduced, and the cooling and heating volume and air supply volume of the air conditioning system in the target area are controlled to remain unchanged.

[0120] Under this control condition, the number of passengers in the target area during the preset time period decreased, but the load demand parameter for the target area's air conditioning system during the preset time period remained equal to the base air conditioning load. This also indicates that while the passenger load demand for the target area's air conditioning system during the preset time period remained unchanged, the number of passengers in the target area during the preset time period decreased. In this case, it is necessary to both conserve the target area's air conditioning system's energy consumption and meet the comfort requirements of passengers in the target area. Therefore, the fresh air volume of the target area's air conditioning system is reduced, while the cooling, heating, and supply air volumes of the target area's air conditioning system remain constant.

[0121] In other optional implementations, the air-conditioning system of the target area may also be regulated by PID control.
