Description

Technical Field

[0001] The present application relates to the technical field of airport material transportation, and in particular to an energy-saving method, system, device and storage medium for airport baggage transportation. Background Art

[0002] At present, the airport baggage transportation system is a system that provides services for checked baggage of passengers on civil aviation aircraft. Fig. 9 As shown, when passengers check in their luggage, the airport baggage transportation system needs to weigh the luggage, read the luggage tag information, and conduct a luggage security check. The luggage will be transported from the check-in area of ​​the terminal to the security inspection area, the tray sorting processing area, and then to the outbound carousel via a belt conveyor. At the outbound carousel, the luggage will be moved to the luggage trailer by ground service personnel and then transported and carried to the aircraft cargo hold.

[0003] In large hub airports, there are more than 7,000 belt conveyors. The belt conveyors in traditional airport baggage transportation systems need to run all the time until the airport's business for the day is over, which results in high electricity consumption.

[0004] The existing energy-saving technology for electromechanical equipment such as belt conveyors mainly uses PLC (Programmable Logic Controller) to achieve automatic energy-saving stop technology when the set time is exceeded. Fig.10 As shown, the specific steps include: The photoelectric sensor installed at the end of the belt conveyor detects whether there is luggage passing through. When there is luggage passing through, the photoelectric sensor is blocked and outputs a "0" signal; when there is no luggage passing through, the photoelectric sensor is not blocked and outputs a "1" signal. The output signal of the photoelectric sensor is collected through PLC. When the signal is "1", the timing starts. When the signal is "0", the timing stops. When the signal becomes "1" again, the timing starts again, and so on. The timing data is compared with the energy-saving stop time previously set manually through PLC. When the timing data is less than the energy-saving stop time previously set manually, the belt conveyor operates normally; when the timing data is greater than or equal to the energy-saving stop time previously set manually, the PLC controls the belt conveyor to stop automatically.

[0005] When the front baggage enters the belt conveyor at a small flow rate, the belt conveyor cannot enter the energy-saving stop state because the photoelectric sensor signal frequently changes between "0" and "1". If similar situations occur on multiple conveyor lines, the conveyor line capacity cannot be fully utilized.

[0006] In the above method, energy saving is only considered from the perspective of a section of belt conveyor, and energy saving is not considered from the perspective of the overall operation of the airport baggage transportation system. There is still a technical problem of long idling time of belt conveyor, and the degree of energy consumption reduction is limited. Summary of the invention

[0007] The present invention aims to solve the technical problem in the related art that the conveyor will not enter the energy-saving stop state until a period of time has passed after all the luggage has passed through the conveyor, and the degree of energy consumption reduction is limited.

[0013] Passengers place their checked baggage on the check-in weighing conveyor. After the baggage is weighed and barcoded, it passes through an X-ray flaw detector for security inspection and then enters the check-in sending conveyor to wait. When there is free space on the check-in collecting conveyor, the baggage enters the check-in collecting conveyor.

[0017] In this technical solution, the smallest value is selected from the first deviation, the second deviation and the third deviation as the correction coefficient, so that the predicted value of the luggage quantity is infinitely close to the actual value.

[0018] In any of the above technical solutions, further, determining a first correction coefficient and a first deviation according to the second luggage quantity, the first luggage quantity and a preset algorithm specifically includes: According to the formula Generate the first correction coefficient, According to the formula Generate the first deviation, Wherein, m1 represents the first correction coefficient; P1 represents the first deviation; B represents the first quantity of baggage arriving at the horizontal diverter from the check-in counter; A1 represents the second quantity of baggage after checking in at the check-in counter within the process time.

After calculation, it can be known that the first deviation of the second luggage quantity collected by the check-in counter within 1 minute is .

[0020] In any of the above technical solutions, further, determining a second correction coefficient and a second deviation according to the third luggage quantity, the first luggage quantity and a preset algorithm specifically includes: According to the formula Generate the second correction factor, According to the formula Generate the second deviation, Among them, m2 represents the second correction coefficient; P2 represents the second deviation; B represents the first number of luggage arriving at the horizontal diverter from the check-in counter; A2 represents the third number of luggage after the check-in counter scans the barcode gun and RFID antenna to complete the check-in procedures within the process time.

[0021] In this technical solution, for example, the number of third luggage after check-in collected by the barcode scanner and RFID antenna at the check-in counter within 1 minute is A2. After calculation, it can be known that the second deviation of the number of third luggage collected by the barcode scanner and RFID antenna at the check-in counter within 1 minute is .

[0025] The energy-saving system for airport baggage transportation provided by the present invention comprises the following steps: a sensor signal acquisition module acquires input signals of photoelectric switches at the check-in conveyor position, and when the identification signal is "1", it indicates that there is no baggage, and when the identification signal is "0", it indicates that there is baggage; a baggage flow statistics module summarizes and adds the number of signals "0" identified by the sensor signal acquisition module within a unit time; a data correction module compares the number of baggage counted by the baggage flow statistics module with the number of checked baggage messages in the checked baggage message system, and calculates the corrected number of baggage after check-in by using the correction coefficient m; a data comparison module compares the corrected number of baggage after check-in The quantity Pb ​​is compared with the baggage transport capacity N of the conveyor line to determine whether the number of baggage in the next period exceeds the baggage transport capacity N of the conveyor line; the routing control module is used to issue a "close" or "open" command to the horizontal diverter. When the number of baggage in the next period does not exceed the baggage transport capacity N of the conveyor line, the routing control module issues a "close" command to the horizontal diverter, the horizontal diverter swings its arm to the closed position, and all baggage converges to one of the conveyor lines; when the number of baggage in the next period exceeds the baggage transport capacity N of the conveyor line, the routing control module issues an "open" command to the horizontal diverter, the horizontal diverter swings its arm to the open position, and the baggage is transported by two conveyor lines respectively.

[0026] According to a third aspect of the present invention, an energy-saving device for airport baggage transportation is proposed, comprising: a memory and a processor, the memory storing an energy-saving program for airport baggage transportation; the energy-saving program for airport baggage transportation, when executed by the processor, is used to implement the operation of the energy-saving method for airport baggage transportation of the first aspect.

DETAILED DESCRIPTION

[0033] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0035] The airport baggage transportation system refers to the equipment assembly used for the transportation, storage, sorting and security inspection of passengers' checked baggage at the airport. With the continuous improvement of the modernization of the airport baggage transportation system and the increase in the types of equipment, the power consumption of the airport baggage transportation system has also gradually increased.

[0036] In order to solve the problem that in the related art, energy saving is only considered from the perspective of a section of belt conveyor, but energy saving is not considered from the perspective of the overall operation of the airport baggage transportation system, and there is still a technical problem that the belt conveyor has a long idling time and the degree of energy consumption reduction is limited, this embodiment provides an energy-saving method, system, device and storage medium for airport baggage transportation, specifically, Figures 1 to 8 shown.

[0037] According to the first aspect of this embodiment, Figure 1 As shown, an energy-saving method for airport baggage transportation is proposed. The energy-saving method is applied to an airport baggage transportation system. The airport baggage transportation system at least includes a horizontal diverter 40, a baggage flow sensing subsystem, a routing decision subsystem and multiple conveyor lines, and specifically includes the following steps: Step S102: Acquire the quantity of baggage introduced into the airport baggage transportation system within a unit time; Step S104: obtaining a correction coefficient, and correcting the luggage quantity according to the correction coefficient to obtain a corrected luggage quantity; Step S106: opening the horizontal diverter based on the fact that the corrected baggage quantity is greater than the maximum baggage quantity of the conveyor line; Step S108: closing the horizontal diverter based on the fact that the corrected baggage quantity is less than or equal to the maximum baggage quantity of the conveying line.

[0038] In step S102, the number of luggage after check-in is obtained by acquiring sensor signals of various conveyors on the conveyor line and the number of checked baggage messages.

[0039] In step S104, the amount of luggage after check-in is corrected by setting a correction coefficient to obtain a corrected amount of luggage after check-in.

[0040] Before implementing step S106 and step S108, it is necessary to obtain the maximum baggage conveying volume on the conveying line to obtain a baggage conveying threshold.

[0041] In step S106 and step S108, the revised number of baggage after check-in is compared with the baggage delivery threshold; if the revised number of baggage after check-in is greater than the baggage delivery threshold, the horizontal diverter 40 on the conveyor line opens multiple conveyor line branches; if the revised number of baggage after check-in is less than or equal to the baggage delivery threshold, the horizontal diverter 40 on the conveyor line only opens one conveyor line branch.

[0042] like Figure 7 As shown in the figure, when the corrected number of baggage after check-in is less than or equal to the baggage conveying threshold, the horizontal diverter 40 on the conveyor line only opens one conveyor line branch and closes the other conveyor line branches. The horizontal diverter 40 changes the conveying direction of the baggage in the horizontal direction, that is, the horizontal diverter 40 diverts the baggage from one conveyor line to any one of the two conveyor lines. By predicting and analyzing the front-end baggage flow and adjusting the baggage routing, the conveyor line capacity of the airport baggage transportation system can be fully utilized, so that the conveyor line with a small baggage flow can be emptied in time, and the conveying equipment enters the energy-saving stop mode, achieving a full energy-saving effect.

[0043] Under the conditions of the same equipment and the same amount of luggage, compared with the energy-saving methods in the related art, the energy-saving method for airport luggage transportation provided by this embodiment reduces electricity consumption by more than 5%, thereby significantly reducing electricity consumption.

[0044] The baggage flow sensing subsystem counts the number of baggage passing on the conveyor through photoelectric sensors.

[0045] The routing decision subsystem issues the action instruction of the horizontal diverter 40 to the motor, and controls the opening and closing of the horizontal diverter 40 through the motor.

[0046] like Figure 4 As shown, the airport baggage transportation system also includes a check-in weighing conveyor 310, a check-in sending conveyor 320 and a check-in collecting conveyor 330, wherein an X-ray flaw detector 340 is connected between the check-in weighing conveyor 310 and the check-in sending conveyor 320, and a check-in collecting conveyor 330 is provided on the side of the check-in sending conveyor 320 away from the X-ray flaw detector 340.

[0047] The passenger places the checked baggage on the check-in weighing conveyor 310. After the baggage is weighed and the baggage barcode is affixed, the baggage passes through the X-ray flaw detector 340 for security inspection, and then enters the check-in sending conveyor 320 to wait. When there is a vacant position on the check-in collecting conveyor 330, the baggage enters the check-in collecting conveyor 330. It should be noted that each check-in island is equipped with one check-in weighing conveyor 310, one X-ray flaw detector 340, and one check-in sending conveyor 320, and each check-in collecting conveyor 330 is usually connected to 7-16 check-in sending conveyors 320.

[0048] In step S102, the following steps are specifically included: Step S1021: Collecting photoelectric sensor signals of the check-in weighing conveyor, the check-in sending conveyor and the check-in collecting conveyor; Step S1022: The amount of luggage introduced into the airport luggage transportation system per unit time is obtained based on the change in the photoelectric sensor signal.

[0049] It should be noted that the photoelectric sensor is used to detect the number of luggage in transit after check-in procedures. The photoelectric sensor signal is connected to the PLC input point of the nearby check-in equipment. The nearby check-in equipment can be one of the check-in weighing conveyor 310, the X-ray flaw detector 340, the check-in sending conveyor 320 and the check-in collecting conveyor 330. The PLC is only suitable for a single check-in equipment to receive the photoelectric sensor signal, and the PLC counts the number of luggage transported by the conveyors of each check-in counter within a period of time.

[0050] For example, the PLC of a check-in device collects 10 photoelectric sensor input signals within 3 minutes, which change from "1" to "0" and then to "1", indicating that 10 pieces of luggage were checked in at the check-in counter and imported into the airport luggage transportation system within these 3 minutes. That is, P = 10 pieces / 3 minutes.

[0051] The airport baggage transportation system also includes a check-in counter, a barcode scanner and RFID antenna at the check-in counter, and a checked baggage message system. The number of baggage imported into the airport baggage transportation system per unit time is obtained. In step S102, the following steps are specifically included: Step S1023: Acquire the first quantity and flow time of the luggage arriving at the horizontal diverter from the check-in counter; Step S1024: collecting the number of second luggage after checking in at the check-in counter within the process time, the number of third luggage after checking in at the check-in counter using the barcode scanner gun and RFID antenna, and the number of checked luggage messages in the checked luggage message system; Step S1025: determining a correction coefficient according to the first baggage quantity, the second baggage quantity, the third baggage quantity and the number of checked baggage messages, the correction coefficient being used to correct the number of baggage introduced into the airport baggage transportation system per unit time.

[0052] Considering the factors that oversized baggage is delivered from another oversized baggage check-in place, the photoelectric sensor signal is triggered incorrectly, and passengers do not put their baggage into the airport baggage transportation system after checking in, it is necessary to correct the baggage quantity Pa obtained in step S102, and the correction coefficient is m (m>0). The corrected baggage quantity after check-in is Pb, Pb=mPa.

[0053] The value of the correction coefficient m is calculated using a deviation algorithm with a period of 3 minutes.

[0054] A correction coefficient is set based on the number of checked-in luggage arriving at the horizontal diverter 40 from the check-in counter within a unit time, the number of checked-in luggage obtained by the barcode scanner and RFID antenna (Radio Frequency Identification, transponder antenna) at the check-in counter within a unit time, and the number of checked baggage messages obtained within a unit time. Through the correction, the obtained number of checked-in luggage is made close to the actual number of transported luggage.

[0055] In step S1025, determining the correction coefficient according to the first luggage quantity, the second luggage quantity, the third luggage quantity and the number of checked baggage messages specifically includes the following steps: Step S1025a: determining a first correction coefficient and a first deviation according to the second luggage quantity, the first luggage quantity and a preset algorithm; Step S1025b: determining a second correction coefficient and a second deviation according to the third luggage quantity, the first luggage quantity and a preset algorithm; Step S1025c: determining a third correction coefficient and a third deviation according to the number of checked baggage messages, the first number of baggage and a preset algorithm; Step S1025d: Determine a correction coefficient according to the minimum deviation among the first deviation, the second deviation and the third deviation.

[0056] In step S1025a, determining the first correction coefficient and the first deviation according to the second luggage quantity, the first luggage quantity and a preset algorithm specifically includes: According to the formula Generate the first correction coefficient, According to the formula Generate the first deviation, Wherein, m1 represents the first correction coefficient; P1 represents the first deviation; B represents the first number of luggage arriving at the horizontal diverter 40 from the check-in counter, which can also be understood as the actual number of luggage arriving at the horizontal diverter 40 from the check-in counter; A1 represents the second number of luggage after checking in at the check-in counter within the process time.

[0057] For example, the second luggage quantity that takes 1 minute to reach the horizontal diverter 40 from the check-in counter is A1. After calculation, it can be known that the first deviation degree of the second luggage quantity collected by the check-in counter within 1 minute .

[0058] In step S1025b, determining the second correction coefficient and the second deviation according to the third luggage quantity, the first luggage quantity and a preset algorithm specifically includes: According to the formula Generate the second correction factor, According to the formula Generate the second deviation, Among them, m2 represents the second correction coefficient; P2 represents the second deviation; B represents the first number of luggage arriving at the horizontal diverter 40 from the check-in counter; A2 represents the third number of luggage after the check-in counter scans the barcode gun and RFID antenna to complete the check-in procedures within the process time.

[0059] For example, the number of third luggage after check-in collected by the barcode scanner and RFID antenna at the check-in counter within 1 minute is A2. After calculation, it can be known that the second deviation of the number of third luggage collected by the barcode scanner and RFID antenna at the check-in counter within 1 minute .

[0060] In step S1025c, determining the third correction coefficient and the third deviation according to the number of checked baggage messages, the first number of baggage and a preset algorithm specifically includes: According to the formula Generate the third correction factor, According to the formula Generate the third deviation, Among them, m3 represents the third correction coefficient; P3 represents the third deviation; B represents the first amount of baggage arriving at the horizontal diverter 40 from the check-in counter; A3 represents the number of checked baggage messages in the checked baggage message system within the process time.

[0061] For example, the number of checked baggage messages obtained within 1 minute is A3. After calculation, it can be known that the third deviation degree of the number of checked baggage messages in 1 minute predicts the number of baggage .

[0062] The correction coefficient with the smallest deviation is set to correct the number of baggage after check-in. The function expression of the correction coefficient with the smallest deviation is: P(x) = min{P1, P2, P3}, Among them, P1 represents the first deviation of the second luggage quantity collected by the check-in counter within a unit time; P2 represents the second deviation of the third luggage quantity collected by the barcode scanner and RFID antenna at the check-in counter within a unit time; P3 represents the third deviation of the luggage quantity predicted by the number of checked baggage messages within a unit time.

[0063] In step S1025d, the smallest value among P1, P2 and P3 is selected as the correction coefficient.

[0064] The value of the next time period m is the m value of the prediction method with the smallest deviation, that is, m min .

[0065] The m value of each time period is made to adopt the value selection method with the minimum deviation from the actual baggage quantity data verified in the previous time period, so that the predicted value Pa is infinitely close to the actual value Pb.

[0066] In order to collect the luggage quantity of A1, A2, and A3, Figure 5 As shown, the baggage flow sensing subsystem establishes a field bus interface, a baggage full-process tracking system interface, and a checked baggage message system interface to realize the functions of collecting baggage quantity data in the above three ways.

[0067] Before implementing step S106 and step S108, the baggage transport capacity of each conveyor line, also known as the maximum baggage flow of the conveyor line, needs to be set in advance. For example, the maximum baggage flow of a conveyor line is N. The actual value Pb of the baggage quantity is compared with the maximum baggage flow N of the conveyor line.

[0068] In step S108, Figure 6 As shown, if Pb>N, the horizontal diverter 40 is opened, and the luggage is transported using two conveyor lines; if Pb≤N, the horizontal diverter 40 is closed, and the luggage is transported using one conveyor line.

[0069] Specifically, step 108 also includes the following steps: Step S1081: The baggage flow sensing subsystem obtains the baggage flow Pa of the decision point; Step S1082: perform luggage flow correction to obtain Pb=mPa; When Pb>N, step S1083 and step S1084 are executed: Step S1083: the horizontal diverter is opened, and the baggage is transported using two conveyor lines; Step S1084: Both conveyor lines are running; When Pb≤N, step S1085 and step S1086 are executed: Step S1085: the horizontal diverter is closed, and the baggage is merged into one conveyor line for transmission; Step S1086: All conveyor lines without luggage are stopped to save energy.

[0070] Please continue to refer to Figure 8 ,The white lines in the figure represent the conveyor lines where energy saving is stopped.

[0071] Compared with the related art, the energy-saving method for airport luggage transportation provided by this embodiment has at least the following beneficial effects: (1) By predicting and analyzing the front-end baggage flow and adjusting the baggage routing, the conveyor line capacity of the airport baggage transportation system can be fully utilized, so that the conveyor line with less baggage flow can be emptied in time and the conveying equipment enters the energy-saving stop mode, achieving the effect of full energy saving; (2) Under the conditions of the same equipment and the same amount of luggage, compared with the energy-saving methods in related technologies, the power consumption is reduced by more than 5%, which greatly reduces the power consumption; (3) Reduce the idling time of the conveyor and reduce energy consumption; (4) No new hardware is required, and the transformation is easy and fast.

[0072] This embodiment selects energy consumption data of an airport baggage transportation system under different baggage quantities to verify the proposed energy-saving method for airport baggage transportation.

[0073] Since the power consumption of the airport baggage transportation system is mainly affected by two factors: the amount of equipment in operation and the amount of baggage, under the condition of the same amount of equipment, the greater the amount of baggage, the greater the output of the conveyor and the greater the energy consumption. Therefore, it is necessary to compare the power consumption before and after adopting this energy-saving method under the condition of the same amount of baggage.

[0074] Table 1 shows a comparison of the average daily power consumption before and after the energy-saving method is adopted when the average daily number of luggage is the same. It can be seen that under the condition of the same number of luggage, the energy-saving method can reduce the energy consumption of the airport baggage transportation system by more than 5%.

[0075] Table 1 is a comparison of the average daily electricity consumption before and after the adoption of this energy-saving method.

[0076] Taking the construction of large hub airport H as an example, the construction overview of the terminal area is that the preliminary design target year is 2025, and the annual passenger throughput is 72 million. In this phase, a centralized terminal building will be built to meet the annual passenger throughput of 45 million and the capacity demand of 12,600 people entering and leaving the airport during peak hours. The civil engineering conditions for connecting the satellite finger pier of the APM (Automated People Mover System) and the expansion space of the facilities in the building will be reserved. Subsequently, the satellite hall will be expanded on the south side to meet the demand of 72 million annual passenger throughput. The specific instructions are as follows: The terminal's arrival and departure facilities have an annual passenger handling capacity of 72 million; The arrival and departure facilities in the terminal's main concourse have an annual passenger handling capacity of 45 million; The satellite terminal's arrival and departure facilities have an annual passenger handling capacity of 27 million.

[0077] The peak hour passenger volume corresponding to the annual passenger throughput is shown in Table 2: Table 2 is the data table of peak hour passenger volume corresponding to annual passenger throughput

[0078] Table 3 shows the forecast data of airport H's traffic volume and design parameters.

[0079] Table 3 is the forecast data table of airport H traffic scale and design parameters

[0080] The design of the airport baggage transportation system is based on the predicted data of the airport's peak hour passenger flow parameters, which should be fully considered when designing the scheme. The details are shown in Table 4: Table 4 is a table showing the predicted data based on the peak hour passenger flow parameters of Airport H

[0081] The passenger checked baggage factor is: 0.65 pieces / person for domestic and 1.05 pieces / person for international. The baggage factor is the average number of checked baggage per passenger.

[0082] The lines that need to be configured for the airport baggage transportation system are shown in Table 5.

[0083] Table 5 is a data table of the routes that need to be configured for the airport baggage transportation system

[0084] In Table 5, ATR+OCR is a combination of automatic laser reader (ATR) and optical character recognition (OCR).

[0085] The system processing capacity of the airport baggage transportation system must meet the requirements of the peak hour baggage flow in the following table. The specific requirements are shown in Table 6: Table 6 is a data table of baggage flow in peak hours at the airport

[0086] There are more specific processing capacity indicators for each conveyor line. For example, the check-in island must be able to meet the average baggage flow requirements of each collection conveyor line of the check-in island in the table below. The specific requirements are shown in Table 7: Table 7 is a data table of the average baggage flow of each collection and conveying line

[0087] According to the second aspect of this embodiment, Figure 2 As shown, an energy-saving system 10 for airport baggage transportation is proposed, which includes a sensor signal acquisition module 110, a baggage flow statistics module 120, a data correction module 130, a data comparison module 140 and a routing control module 150. Among them, the sensor signal acquisition module 110 is used to obtain sensor signals on the conveyor line and identify baggage according to the sensor signals; the baggage flow statistics module 120 is used to accumulate and sum the baggage identified by the sensor signal acquisition module 110 within a unit time; the data correction module 130 is used to correct the baggage quantity according to the correction coefficient to obtain the corrected baggage quantity; the data comparison module 140 is used to compare the corrected baggage quantity with the maximum baggage quantity of the conveyor line; the routing control module 150 is used to open the horizontal diverter 40 when the corrected baggage quantity is greater than the maximum baggage quantity of the conveyor line; and close the horizontal diverter 40 when the corrected baggage quantity is less than or equal to the maximum baggage quantity of the conveyor line.

[0088] Specifically, the sensor signal acquisition module 110 acquires the input signal of the photoelectric switch at the check-in conveyor position, and when the identification signal is "1", it indicates that there is no luggage, and when the identification signal is "0", it indicates that there is luggage; the luggage flow statistics module 120 summarizes and adds the number of signals "0" identified by the sensor signal acquisition module 110 per unit time; the data correction module 130 compares the number of luggage counted by the luggage flow statistics module 120 with the number of checked luggage messages in the checked luggage message system, and calculates the corrected number of luggage after check-in procedures Pb through the correction coefficient m; the data comparison module 140 compares the corrected number of luggage after check-in procedures Pb with the number of checked luggage messages of the conveyor line The routing control module 150 is used to issue a "close" or "open" instruction to the horizontal diverter 40. When the number of luggage in the next period does not exceed the luggage transportation capacity N of the conveyor line, the routing control module 150 issues a "close" instruction to the horizontal diverter 40, and the horizontal diverter 40 swings to the closed position, and all the luggage is converged to one of the conveyor lines; when the number of luggage in the next period exceeds the luggage transportation capacity N of the conveyor line, the routing control module 150 issues an "open" instruction to the horizontal diverter 40, and the horizontal diverter 40 swings to the open position, and the luggage is transported by two conveyor lines respectively.
