Description
Technical Field
The invention relates to the field of airport management, in particular to a parking control method and system for an airport, control equipment and a computer readable storage medium.
Background
With the rapid development of traffic systems and the obvious increase of travel frequency, the demands of people on travel in terms of efficiency and convenience become clearer. In the case of taking an airplane out, a combined travel mode of taking a car from home to an airport and then taking the airplane to a destination by self-driving has become a common travel mode. Accordingly, airports are equipped with parking lots for providing parking services for vehicles prior to the return trip of travelers. Due to the complexity of traffic systems, objectively there are usually the following problems:
1) a traveler is not familiar with the parking lot, which will affect the efficiency of the traveler's vehicle to reach the airport configured parking lot to some extent, for example, situations may arise: because travelers are not familiar with the parking lot, the travelers may rotate around the extensive parking lot pocket, so that the problems of low efficiency and long time consumption for finding the parking space occur;
2) after parking is finished, a traveler mostly adopts ways of recording typical signs of a parking area and the like to determine the parking position of the vehicle, the way of finding the vehicle by memory can increase the time of finding the vehicle reversely to a certain extent, and particularly under the condition that the traveler is not familiar with the structure of a parking lot, the traveler experience which shows that the burden of traveling is increased is obviously brought;
3) for the parking lot charging service of the airport, problems such as difficult fee payment and low efficiency may be encountered, which may cause phenomena such as jam at the fee payment entrance to a certain extent, which may be accompanied with a problem of a certain decline in traveler experience.
In order to solve the above problems, means such as setting a reverse car searching terminal machine in a parking lot, setting a display screen for displaying an empty parking space in an area, and using etc. at an exit of the parking lot have appeared. These approaches solve, to some extent or in some part, the above problems, but suffer from at least the following disadvantages: improvements are often directed to local problems. Therefore, for a single specific traveler, when the traveler adopts a combined travel mode of traveling from home to an airport by a self-driving mode and then traveling to a destination by an airplane, a refinement scheme capable of obviously improving the experience of the traveler is provided for the traveler so as to meet the demand and improve the experience of the traveler, and the combined travel mode has very definite practical significance.

Obviously, the parking control method for the airport of the present invention can also be implemented by APP on a mobile phone, vehicle-mounted equipment, other terminals, etc.
Referring to fig. 1, fig. 1 is a flow chart illustrating a parking control method for an airport according to an embodiment of the present invention. As shown in fig. 1, the parking control method for an airport of the present invention mainly includes the steps of:
s101, a luggage reservation step:
this step is mainly to send the baggage corresponding to the traveler to the airport in a manner separated from the current vehicle so as to complete the consignment of the baggage.
In one possible embodiment, the consignment of the property is done with the baggage corresponding to the traveler being individually sent to the airport. The completion of the step mainly comprises two parts of a luggage consignment function and a consignment fee settlement function, specifically:
and the traveler inputs the traveler information such as the flight date, flight number, take-off place, landing place and home address of the journey corresponding to the traveler, the time for getting express at home and the like on the interactive interface of the small program. Through the cooperation of the airport and a third party such as an express company, on the premise that the information of the travelers has safety guarantee, the airport transfers the information of the travelers to the express company to realize information exchange, and the express company assigns employees of the express company through the information of the travelers.
According to the appointed time for getting the express delivery at home and the location determined based on the home address, if the luggage of the travelers is taken in the mode of getting the goods at home, if the number of the luggage is checked, whether the luggage contains the goods prohibited from being shipped or not is checked, and the luggage is guaranteed to be completely packaged, the express company can guarantee to transport the luggage to the airport in advance and handle the luggage shipment procedures and the like on the airport as much as possible.
In addition, the luggage checking process also comprises the following steps: uploading the weight of the luggage to a background according to the airport consignment result, if the weight of the luggage exceeds the free consignment limit, calculating the cost required to be paid by the traveler and sending the information related to the cost to the traveler, for example, providing a payment interface capable of directly performing payment operation for the traveler, for example, skipping to the payment interface capable of directly performing payment operation by a small program.
S103, parking space reservation step:
the step is mainly used for reserving the target parking space to which the current vehicle is about to arrive.
Preferably, the parking space reservation step specifically includes:
and S1031, the small program receives the alternative parking spaces recommended by the airport and determined according to the information of the travelers and the parking space information of the airport.
In a possible embodiment, S1031 is specifically:
the recommendation of the alternative parking space is done by the flight information of the travelers including but not limited to, the current vehicle information, the individual needs of the travelers, the expected parking time of the vehicle, etc. and the parking space information of the airport like the parking space occupation information as acquired by including but not limited to a high definition camera, the parking space which is determined/predicted from parking data, etc. to be free at the expected parking time, etc.
It can be understood that, those skilled in the art can make rules that the parking spaces can belong to alternative parking spaces according to actual conditions. Such as may be: the alternative parking spaces can comprise one or more; for travelers (such as SVIP, VIP and common travelers) with different grades, the number of recommended parking spaces and specific parking spaces can be different; and the like.
For example, the flight information of the traveler is obtained by the flight number, departure date, and departure and landing place of the airplane, and the airport parking lot closest to the terminal of the airport from which the traveler departed is locked by the flight information filled by the traveler; if the current vehicle information can comprise the vehicle type, the license plate number and the like of the vehicle, and the parking space suitable for the vehicle type is screened out in the airport parking lot closest to the airport terminal through the vehicle information; the individual needs of the traveler may include, but are not limited to: the traveler selects long-term parking or short-term parking, if the traveler selects long-term parking, the traveler recommends a long-term parking area, and if the traveler selects short-term parking, the traveler recommends a short-term parking area; the traveler selects fee priority or timeliness priority, if the traveler selects fee priority, the parking space far away from the exit is recommended, and if the traveler selects timeliness priority, the parking space near the exit is recommended; and the like. The parking space occupation information acquired by the high definition camera can be as follows: the method comprises the steps of capturing a currently parked vehicle through a high-definition camera, identifying the license plate number of the currently parked vehicle through an image identification technology (for example, positioning a license plate area in the vehicle, carrying out image preprocessing on the license plate area, and outputting the license plate number of the license plate area through character segmentation and identification), outputting the identified license plate number to related data, and obtaining real-time occupation information of each parking space.
And S1033, according to the alternative parking spaces, determining a target parking space to which the current vehicle is about to arrive by the traveler in an interactive interface of the small program.
And S1035, reserving the target parking space by the traveler in a mode of operating an interactive interface of the small program.
In a possible embodiment, S1031 and S1035 are specifically:
if the recommended alternative parking spaces comprise a plurality of alternative parking spaces and the traveler receives the alternative parking spaces, the traveler needs to select one of the alternative parking spaces as a target parking space on the interactive interface, and then clicks for reservation, so that reservation of the target parking space can be completed;
if the recommended alternative parking spaces comprise one parking space and the traveler receives the alternative parking space, directly clicking on an interactive interface to determine and reserve, namely, completing reservation of the target parking space;
if the traveler does not accept the recommended alternative parking spaces (no matter the alternative parking spaces include one or more parking spaces), the traveler can click the option of the parking space allowed to be selected on the interactive interface and jump to a parking space selection interface;
on this basis, the passerby can select out the target parking stall voluntarily, if can be: calling flight information of a traveler to display a plan view of an airport parking lot closest to an airport terminal of an airport from which the traveler departs; displaying the occupation information of each parking space in the airport parking lot (dynamically displaying the occupation state of the parking space at the moment in real time; displaying gray occupied parking spaces to indicate that the parking spaces are not selectable, and displaying green unoccupied parking spaces to indicate that the parking spaces are selectable); a traveler selects one of the vacant parking spaces displaying green according to the parking condition as a target parking space, and then clicks the reservation to finish the reservation of the target parking space;
s105, parking space navigation:
this step includes at least an indoor navigation function enabling navigation of a traveler driving a vehicle from a set position (e.g., a parking lot) entering an airport to a route of a target parking space.
Preferably, this step further includes an outdoor navigation function enabling a traveler to navigate the vehicle from the location of his vehicle (e.g., a parking garage corresponding to the traveler's home address) to a set location at the airport (e.g., the aforementioned parking garage).
In one possible implementation manner, the outdoor navigation function is implemented as follows:
the mode of jumping to outdoor navigation can be two types: the first mode is that the traveler clicks and selects the outdoor navigation on a page where parking space reservation is successful, the second mode is that the outdoor navigation is directly selected on a home page of an interactive interface, and the system plans out the current optimal path (default path) according to the current reservation order of the traveler and automatically starts the outdoor navigation. The outdoor navigation function may be implemented, for example, by invoking a grand map, an Tencent map, a Baidu map, etc. to navigate to a parking lot at a selected airport. Of course, the system may also plan another driving route according to other requirements of the traveler, that is, the default route is replaced with another planned driving route.
In one possible implementation, the indoor navigation function is implemented as follows:
the mode of jumping to indoor navigation can be two types: the first mode is to seamlessly switch from outdoor navigation to indoor navigation after a traveler enters an airport parking lot, the second mode is to select indoor navigation on the home page of an interactive interface, and the system starts indoor navigation based on a target parking space in an existing reservation order of the traveler.
In a preferred embodiment, the indoor navigation function is realized by the following steps:
the method comprises the steps of adopting Bluetooth with low power consumption, carrying out position calibration on travelers through a Kalman filtering algorithm and an RSSI-distance algorithm, adopting a Floyd shortest path algorithm to carry out optimal path planning of indoor navigation, and carrying out Animation rendering of navigation on a front-end interface of a small program through an Animation component of a deep development small program. Specifically, the method comprises the following steps:
s1051, calibrating the position of a traveler, wherein the steps specifically comprise:
s10511, the traveler turns on the Bluetooth function and is used for receiving the RSSI value of the Bluetooth beacon iBeacon module arranged in the airport parking lot.
S10513, RSSI denoising processing based on Kalman filtering: in practical application, the RSSI value is a time-varying signal, and the environment and the measurement distance are fixed, the RSSI value of the bluetooth low energy has a certain system error, and meanwhile, since the RSSI value received by the mobile phone has a certain observation error, the invention defines a kalman filter to perform noise reduction processing on the RSSI value of the signal, and the specific equation involved in the noise reduction processing is as follows:
(1) prediction covariance equation: the estimated covariance of the time instant system (p-1) + the estimated covariance of the time instant system + the noise covariance in the process between the two time instants;
(2) kalman gain equation: the kalman gain is the estimated covariance of the system at time p/(the estimated covariance of the system at time p + the observed noise covariance);
(3) updating an optimal value equation: the optimal value of the state variable at the time p is the predicted value of the state variable + Kalman gain (the measured value of the state variable-the predicted value of the state variable);
(4) updating the covariance equation: and (3) transferring the covariance of the system (the estimated covariance of the system at the moment p) to the next operation, namely (p +1) operation.
And S10515, after Kalman filtering denoising treatment, calculating the distance value according to a formula.
In a specific embodiment, the distance value is calculated by:
in an actual environment, signals of the iBeacon module can continuously weaken on a propagation path, and specifically, the farther the mobile phone is away from the iBeacon module, the weaker the measured signals are, and the smaller the RSSI value is. Moreover, the RSSI value has great fluctuation, therefore, in the invention, a regression type mathematical model (for example, the formula can be obtained by using a fit function in Matlab to realize log function fitting, the mathematical principle of the formula is a least square method polynomial curve, and the like) is adopted to collect a large number of RSSI values at any position of the beacon equipment (iBeacon module), and a more accurate distance value is obtained through the form of function fitting.
Such as may be: and characterizing the relation between the distance and the RSSI through a shadow fading model. In actual environment, radio signals are not unobstructed in a propagation path, and when obstacles are met, the signals are reflected or absorbed, so that a shadow effect is caused. In an actual indoor environment, there are many obstacles around the receiver, and the shadow effect caused by these obstacles causes the median value of the field intensity at the receiving antenna to change, and the fading caused by this cause becomes shadow fading. Also, the value of the field strength is also called slow fading because it changes slowly due to the physical environment.
Research observation shows that the median value of the field intensity of the received signal approximately follows the log-normal distribution. The relationship of shadow fading to propagation distance and shadow loss can be expressed as the formula:
RSSI＝-10αlog 10 (d/d 0 )+K (1)
in formula (1), α represents a path loss exponent that varies according to ambient environmental conditions, d represents a distance between the bluetooth beacon and the handset, and d 0 Is the reference distance between the Bluetooth beacon and the mobile phone, generally takes a value of less than or equal to 3m, such as about 1m, and K is d 0 The average of the RSSI values at (a).
And (3) changing the base of the formula to obtain a fitting function as the formula:
RSSI＝C*ln(d)+m (2)
in the formula (2), C is equal to (-10) × α in value, m is equal to (K-10) in value, C and m have different values in different environments, and RSSI test needs to be performed for each parking lot, so that specific parameter setting is performed.
And calculating the distance value of the iBeacon module from the traveler by combining the fitting function with the obtained RSSI value.
S10517, after the distance value is calculated according to the formula, the position of the traveler in the parking lot of the airport is estimated through the indoor positioning algorithm (estimating the maximum likelihood value) based on the maximum likelihood method.
Because of the instability of the signal of the iBeacon module, the distance value obtained by calculating the RSSI value inevitably has an error in an objective level, and therefore on the basis, the maximum likelihood value is estimated by adopting a maximum likelihood method, so that the position of a traveler in a parking lot of an airport is positioned. The positioning principle of the maximum likelihood method is as follows:
assuming that an unknown node to be measured and n known nodes exist in a region, when the measured distances from the unknown node to be measured to all the known nodes are known, a distance equation between the known node and the unknown node to be measured can be obtained. Specifically, the method comprises the following steps:
let the coordinates of n known nodes be (x) respectively 1 ，y 1 )，(x 2 ，y 2 )，(x 3 ，y 3 )…(x n ，y n ) These have already beenThe distances between the known node and any unknown node (x, y) to be measured are d 1 ，d 2 ，d 3 …d n Then there is the following system of equations (containing n equations, each being the distance between two points in the two-dimensional coordinate system):
starting with the first (top-down) equation, subtracting the last equation in turn, the system of equations can be expressed as AX ═ B, where A, X, B are:
the standard least square method in the form of matrix is adopted for estimation, and the coordinate solution of the unknown node to be measured can be obtained as follows:
X＝(A T A) -1 A T B# (7)
s10517, based on the above coordinate solution (the current position of the traveler (vehicle corresponding to the traveler)) and the target parking space (the position to which the vehicle needs to reach), perform the optimal path planning for indoor navigation.
In a possible implementation mode, a Floyd shortest parking space path algorithm based on a BRP function is adopted to carry out optimal path planning. The core idea of the Floyd algorithm is as follows:
(1) the shortest path from node i to j has two possibilities: directly from i to j and from i to j through several nodes k to j;
(2) using map (i, j) to represent the distance of the shortest path between nodes i and j, and checking whether map (i, k) + map (k, j) < map (i, j) is established for each node k;
(3) if true, make map (i, j) ═ map (i, k) + map (k, j); each k is traversed and each update is divided by the number (distance) of the k row and the k column.
In this way, under the condition that the position of the target parking space reserved by the traveler is known, the optimal path corresponding to indoor navigation is planned based on the determined current position of the traveler, and the real-time indoor navigation function is realized based on the optimal path.

in the formula (8), t l Actual travel time, t, required for passing a vehicle through a section l in a parking lot l0 The time required for free running of the vehicle when the road section is in the empty static state is different, because the path parameters with different lengths and widths are different, and even though the road sections are all parking lots, the parking lots are different, therefore, the empty static state of the road section needs to be reasonably set according to specific road sections and maps for specific parking lots, Q is the actual traffic volume passing through the road section, the unit is pcu/h, C is the actual traffic capacity of the road section, namely the number of vehicles actually passing through the road section in unit time, the unit is pcu/h, alpha/beta is a model undetermined parameter, and exemplarily, the reference values of alpha and beta are 0.15 and 4 respectively.
S107, reverse vehicle searching:
the step is mainly used for searching the current vehicle parked in the target parking space after a traveler arrives on a return journey and needs to take the vehicle.
If the applet can respond to the click of the traveler on the display/interactive interface to start the reverse car-finding function, after the start, if the user can input information such as the license plate number of the car in the display/interactive interface, the parking space of the parked car can be defined as the target position based on the information, and the position of the traveler can be calibrated and a car-finding path can be planned based on the position in a manner similar to the indoor navigation function.
S109, automatic payment:
this step is mainly used to pay the costs associated with parking actions in the case of a traveler taking the car. If the traveler drives the vehicle away from the target parking space, the traveler can jump to the interface for automatic payment after clicking the display/interactive interface of the small program (for example, displaying to immediately take the vehicle).
