The embodiment of the invention provides a parking management method and a parking management system, which are used for parking management through more than one positioning mode, so that parking space management is more perfect.
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Referring to fig. 1, a specific process in an embodiment of the present invention is described below, where an embodiment of a parking management method in an embodiment of the present invention includes:
101. monitoring whether vehicles with vehicle state changes exist in a parking area or not through a first positioning mode and a second positioning mode; if so, acquiring the position information of the vehicle in a positioning mode of monitoring the state change of the vehicle;
the parking management system can monitor whether a vehicle with a changed vehicle state exists in a parking area through a first positioning mode and a second positioning mode, the first positioning mode is different from the second positioning mode, when the vehicle with the changed vehicle state is monitored through the first positioning mode, first position information of the vehicle or first position information of a parking space where the vehicle is located is obtained through the first positioning mode, when the vehicle with the changed vehicle state is monitored through the second positioning mode, second position information of the vehicle is obtained through the second positioning mode, and the two positioning modes are mutually independent and do not influence each other. The state change of the vehicle includes that the vehicle enters the parking area, the vehicle leaves the parking area, the position of the vehicle in the parking area is changed, and the like. In practical applications, when roadside parking is performed, the parking area may be the whole street, may also be an area including a plurality of parking spaces, and may also be a single parking space. In the case of a parking lot, the parking area may be the entire parking lot, may be a plurality of parking spaces, or may be a single parking space. When the parking area is the whole street or the whole parking lot, the parking management system monitors the vehicles in the whole area including the parking area and the non-parking area through two positioning modes and judges whether the vehicle state changes. When the parking area is a plurality of parking spaces or a single parking space, only the state of the vehicle in the parking space area needs to be monitored whether to change, and the vehicle state in the non-parking area is not monitored any more. And the system performs further management operation according to the monitoring result. And if the state change of the vehicle does not exist in the parking area, no other operation is carried out, and the monitoring is continued.
102. When first position information of the vehicle or the parking space is acquired through a first positioning mode, judging whether second position information of any vehicle corresponding to the first position information is acquired through a second positioning mode; if not, executing step 103, if yes, executing step 104;
after the state change of the vehicle in the parking area is judged through the first positioning mode, the first position information of the vehicle or the parking space where the vehicle is located is obtained through the first positioning mode. The two positioning modes are independent, when one positioning mode monitors that the state of the vehicle in the parking area changes, the position information of the vehicle or the parking space can be independently obtained, then the system can automatically search whether the position information of the same position exists in the other positioning mode, and if the state of the same vehicle is monitored in the other positioning mode, namely the second position information corresponding to the first position information exists, the two positioning modes are judged to monitor the same vehicle.
It should be noted that the first position information and the second position information correspond to the same position, and are not strictly limited to the first position information being completely the same as the second position information, and as long as the difference between the first position information and the second position information is smaller than the difference threshold, the first position information and the second position information can be considered to correspond to the same position. For example, the difference threshold is set to the length of one vehicle body, and the position of the same vehicle is determined as long as the first position information and the second position information are different by the distance of one vehicle body.
103. Carrying out charging management on the vehicle through a first positioning mode;
and if the first position information and the second position information are judged not to correspond to the same vehicle, carrying out charging management on the vehicle through a first positioning mode.
104. And carrying out charging management on the vehicle through a second positioning mode.
And if the first position information and the second position information are judged to correspond to the same vehicle, carrying out charging management on the vehicle through a second positioning mode.
The method comprises the steps of judging whether the state change of the vehicle exists in a parking area through a first positioning mode and a second positioning mode, and judging whether second position information of any vehicle corresponding to first position information is acquired through the second positioning mode when the first position information of the vehicle or a parking space is acquired through the first positioning mode; when the first position information and the second position information do not correspond to the same position, namely the same vehicle, the vehicle is subjected to charging management through the first positioning mode, and when the first position information and the second position information correspond to the same position, the vehicle is subjected to charging management through the second positioning mode. Like this, carry out parking management through first locate mode and second locate mode, compare with prior art, can perfect parking stall management.
In practical use, the first positioning mode may be a radar positioning mode, and the second positioning mode may be a UWB positioning mode.
The UWB antenna and the UWB electronic tag can be applied to parking management, and when a vehicle provided with the UWB electronic tag enters an antenna coverage area, the UWB technology can be used for positioning the vehicle with high precision. In order to reduce the power consumption of the UWB electronic tag, two ways can be used to reduce the power consumption in practical process. 1) Wireless wake-up mode: the UWB electronic tag uses wake-up signals of a base station, the frequency range of the wake-up signals is not limited to 433MHz, 900MHz, 2.4GHz, 5.8GHz and the like, when a vehicle provided with the UWB electronic tag enters a parking area in a road, the UWB electronic tag is woken up and enters a working mode by receiving periodic wake-up signals sent by the roadside base station through a wake-up link, UWB signals are periodically transmitted (such as at an interval of 1s), a UWB antenna receives the UWB signals, and the UWB electronic tag is positioned in real time through a UWB communication link. 2) A motion awakening mode: an acceleration sensor is used in the UWB electronic tag, when the vehicle stops, the acceleration sensor has no signal, and the UWB electronic tag is in a dormant state; when the vehicle starts, the acceleration sensor activates the UWB electronic tag to enable the UWB electronic tag to emit UWB signals, the UWB antenna receives the UWB signals, and the UWB electronic tag is located in real time through the UWB communication link. The time when the vehicle with the UWB electronic tag enters and exits the parking space is compared, the parking time of the vehicle can be determined, and fee deduction is carried out through a background. When the UWB electronic tag is installed on a vehicle, the UWB electronic tag is generally bound with vehicle information and monthly card/bank card information, so that background fee deduction is facilitated.
Radar positioning can also be used for parking management, and the specific process is generally as follows:
1) the radar antenna periodically sends radar pulse signals;
the radar signal is not limited to use in a certain frequency band (e.g., 24GHz, 77GHz, etc.), or a lidar is used.
2) Receiving a radar echo signal by a radar antenna;
the radar processor may perform signal processing on the radar echo signal, such as clutter rejection, and eliminate the ground reflection signal by obtaining the proximity difference.
3) Acquiring a current vehicle position;
the arrival angle of the vehicle can be obtained according to the echo signal intensity of the two same beams, the distance of the vehicle can be obtained according to the echo time, and the position of the vehicle can be obtained according to the arrival angle and the distance.
4) Distinguishing the specific vehicle length through the frequency spectrum width of the radar echo or the continuity of the radar echo;
the radar sensor module sends FSK (Frequency-shift keying) or LFM (linear Frequency modulation) modulation signals to each position of the vehicle body, and the vehicle length is judged according to the continuity conditions of echo signals at different vehicle body positions: for example, if the vehicle body distance information carried in the echo signal is L, judging that the vehicle body distance information is a person or other non-motor vehicles when the L is less than 0.6m, and informing a parking lot management center to use and manage the parking spaces according to the echo information; judging the car as a small car when the L is more than 0.6m and less than 5m, and informing a car owner and a parking lot management center to use and manage the parking space according to the car type information; judging the vehicle as a large vehicle when L is more than 6m and less than Xm, wherein Xm represents the maximum vehicle type length allowed to stop in the parking lot, and informing a vehicle owner and a parking lot management center to use and manage the parking space according to the vehicle type information; and when Xm is less than L, judging the parking place as a wall or other large obstacles, and informing a parking lot management center to use and manage the parking places according to the echo information.
For vehicle length identification, the identification can be carried out by judging the width of the frequency spectrum. Echoes of different distances produce different spectral lines in the baseband spectrum. The distance resolution of this item is 0.6m (B)n250 MHz). The distance resolution is related to the bandwidth of the signal, i.e. a 4.8 meter car may produce 8 lines, and a 10 meter car will necessarily produce more lines. Therefore, the width of the continuous frequency spectrum can be judged to judge which type of vehicle.
5) And carrying out charging management on the vehicle according to the vehicle position information and the vehicle length information.
The specific process of parking management through radar positioning and UWB positioning in the embodiment of the present invention is described below, the embodiment of the method is based on a parking management system, the parking management system at least includes a server, a radar positioning device and a UWB positioning device, a radar antenna in the radar positioning device can periodically send a radar pulse signal and receive an echo signal, a UWB antenna in the UWB positioning device can detect a UWB signal sent by a UWB electronic tag in real time, and the server can obtain position information of a vehicle and detect a state change of the vehicle through the radar positioning device and the UWB positioning device. Referring to fig. 2, an embodiment of a parking management method according to an embodiment of the present invention includes:
201. monitoring whether a vehicle with a vehicle state change exists in a parking area through a radar positioning mode and a UWB positioning mode, and if so, acquiring the position information of the vehicle through the positioning mode of monitoring the vehicle state change;
the parking management system can judge whether the state of the vehicle changes in the parking area through a radar positioning mode and a UWB positioning mode, when the radar positioning mode monitors the vehicle with the changed state of the vehicle, first position information of the vehicle or a parking place where the vehicle is located is obtained through the radar positioning mode, and when the UWB positioning mode monitors the vehicle with the changed state of the vehicle, second position information of the vehicle is obtained through the UWB positioning mode. The state change of the vehicle includes that the vehicle enters the parking area, the vehicle leaves the parking area, the position of the vehicle in the parking area is changed, and the like. The condition change of the vehicle in the parking area includes that the server only obtains the condition change of the vehicle obtained through radar positioning, or obtains the condition change of the vehicle obtained through radar positioning and UWB positioning at the same time. Because the coverage area of radar is bigger, under the ordinary condition, if the region that sets up radar and UWB monitoring includes that the parking stall is regional and not the parking stall is regional, when the vehicle drives into the within range that the radar monitored from the further distance, the radar can monitor vehicle state change earlier, and UWB monitoring has certain delay, and the position of system real time monitoring vehicle this moment. If the areas monitored by the radar positioning mode and the UWB positioning mode only comprise parking space areas, non-parking space areas are not monitored, the coverage areas of the radar and the UWB are the same, and the state change of the vehicle can be monitored by the radar positioning mode and the UWB positioning mode at the same time under the general condition. Whether the state change of the vehicle is monitored by only a radar or the state change of the vehicle acquired by a radar positioning mode and a UWB positioning mode is acquired simultaneously, the position information is acquired by respectively and independently adopting corresponding positioning modes.
In another case, if only the UWB monitors the vehicle status change, the UWB can directly manage the vehicle without considering whether the radar monitors the vehicle status.
For convenience of understanding, it is assumed that three vehicles (a vehicle, B vehicle, and C vehicle) in the parking area have changed their states, wherein the C vehicle is not equipped with the UWB electronic tag. Therefore, the state changes of the vehicles A, B and C are detected through radar positioning, and the state changes of the vehicles A and B are detected through UWB positioning.
202. When first position information of the vehicle or the parking space is acquired in a radar positioning mode, judging whether second position information of any vehicle corresponding to the first position information is acquired in a UWB positioning mode; if not, go to step 203, if yes, go to step 204;
if the state change of the vehicle in the parking area is judged through the radar positioning mode and the UWB positioning mode, first position information of the vehicle or the parking space, namely the first position information of the vehicle A, the first position information of the vehicle B and the first position information of the vehicle C, is obtained through radar positioning, and second position information of the vehicle, namely the second position information of the vehicle A and the second position information of the vehicle B, is obtained through UWB positioning. In practical use, the first position information and the second position information may correspond to two-dimensional or three-dimensional coordinates in the same coordinate system. The radar positioning mode can judge whether a vehicle and a specific position of the vehicle exist or not through analysis of radar echoes, in another application mode, a coverage area of the radar positioning device is set to be a plurality of parking spaces or a single parking space, the positions of the parking spaces are set in the system, and when the fact that the vehicle exists in the corresponding parking space is monitored, the position of the corresponding parking space is obtained to serve as first position information.
After first position information of a vehicle or a parking space is acquired through radar positioning and second position information of the vehicle is acquired through UWB positioning, it may be determined whether the first position information and the second position information correspond to the same position. The first location information of the car a and the second location information of the car a correspond to the same location, and the first location information of the car B and the second location information of the car B correspond to the same location, but the second location information corresponding to the same location as the first location information of the car C cannot be matched, that is, the first location information and the second location information of the car C do not correspond to the same location. It is understood that since the accuracy of the radar positioning and the UWB positioning is different, the position coordinates corresponding to the first position information and the second position information of the same vehicle are difficult to be completely the same, and therefore, as long as the difference between the position coordinates corresponding to the first position information and the second position information is smaller than the difference threshold, the first position information and the second position information can be considered to correspond to the same position.
203. The vehicle is subjected to charging management in a radar positioning mode;
if the first position information and the second position information are judged not to correspond to the same position, the UWB antenna does not detect the UWB signal of the vehicle at the moment, namely the UWB electronic tag is not installed on the vehicle, and the vehicle can be subjected to charging management through radar positioning at the moment. In the embodiment of the invention, the charging management is carried out on the vehicle C through radar positioning. Optionally, the charging management mode may record the parking time of the vehicle for the radar system, that is, when the vehicle is parked in the parking space, the time counting is triggered to start, and when the vehicle leaves the parking space, the time counting is triggered to end, and the parking fee is notified to charge manually.
204. And carrying out charging management on the vehicle in a UWB positioning mode.
If the first position information and the second position information are judged to correspond to the same position, the fact that the UWB electronic tag is installed on the vehicle is indicated, and the UWB antenna detects a UWB signal sent by the UWB electronic tag, and at the moment, the vehicle can be subjected to charging management through UWB positioning. In the embodiment of the invention, the vehicles A and B are subjected to charging management through UWB positioning. The UWB electronic tag is stored with vehicle information and is bound with a payment account number of a user in the background, and the parking fee can be automatically collected from the background.
The radar positioning and the UWB positioning can be used for parking management, wherein the positioning accuracy of the UWB positioning is high, but a vehicle without a UWB electronic tag cannot be detected, the radar positioning can almost detect all vehicles in a coverage range, but the accuracy is lower than that of the UWB positioning.
